  • Time :

Abstract

Computational molecular modeling, i.e., density functional theory-based molecular modelling (DFT B3LYP/6-31-G*) (DFT/MM) verifies equilibrium geometry and surface electron energy structures of van der Waals force (vdW) molecular aggregates. What should be noted for the energy structures is that DFT/MM-predicted UV/Vis spectra are in good agreement with measured spectra of the aggregates.1) With these viewpoints, effective photoelectrochemical water splitting using mesoporous TiO2 anode and platinum cathode2), and effective water photo-splitting to HOOH and H2 on Pt-loaded TiO2 photocatalysts3) are reinvestigated by DFT/MM. DFT/MM-based UV/Vis spectrum analysis verifies that the anatase Yamashita & Jono’s model of HOTi9O18H has no absorption in the UV region, giving visible absorption spectrum with max=536 nm (strength 0.005). Then, DFT/MM was extended to vdW aggregates of smaller-size TiO2 clusters, (TiO2)n (n=1, 2, 4). Interestingly, DFT/MM-derived UV/Vis spectrum of (TiO2)4 shows max at 377 nm (strength 0.003), and the vdW aggregates of (TiO2)4 with H2O and with platinum triangle pole cluster of Pt6 validates that the molecular-structured TiO2 clusters, (TiO2)1~4 work as effective UV-induced photocatalysts2), and work as a UV-sensitizer in photoelectrochemical water splitting on biased TiO2 anode3).

  • Title: A Circular Economy Approach to Green Energy: Wind Turbine, Waste, and Material Recovery
  • Time :

Abstract

Wind energy has been considered as one of the greenest renewable energy
sources over the last two decades. However, attention is turning to reducing the possible environmental impacts from this sector. We argue that wind energy would not be effectively ‘‘green” if anthropogenic materials are not given attention in a responsible manner. Using the concept of the circular economy, this paper considers how anthropogenic materials in the form of carbon fibers can reenter the circular economy system at the highest possible quality.b This paper first investigates the viability of a carbon-fiber-reinforced polymer extraction process using thermal pyrolysis to recalibrate the maximum carbon fiber value by examining the effect of (a) heating rate, (b) temperature, and (c) inert gas flow rate on char yield. With cleaner and higher quality recovered carbon fibers, this paper discusses the economic preconditions for the takeoff and growth of the industry and recommends the reuse of extracted carbon fibers to close the circular economy loop.

Abstract

An integral ingredient to the operation of industrial or engineering systems, including cooperative robotics, sensor networks, and grid computing, is that its control architecture consisting of hardware and software protocols for exchanging system status and control signals. Current trends to control and monitor the operation of industrial or engineering systems are moving toward the use of an automated agent technology or distributed networked systems (DNS). A distributed networked system is a combination of several units working in collaboration pursuing assigned tasks to achieve the overall goal of the system.
In this presentation, we focus control strategies pertaining to DNS. Specifically, we address the issue of event-triggered feedback strategy in which the unit (local) control is equipped with additional information from neighbors (unit-to-unit communication) to achieve the global motion-coordination task. Our main goal is illuminate the merits/demerits of the foregoing strategy as well as the potential applications.

  • Title:Improvement of Fermentation From Hydrolysate of Green Macroalgae for Bioethanol Production on a Lab- Scale and on a Pilot-Scale
  • Time :

Abstract

The aim of this work was to examine the feasibility of ethanol bioproduction from hydrolysate of macroalgea. Firstly, experiments were carried out with a synthetic medium adjusted on algal hydrolysate composition with four yeast strains: Saccharomyces cerevisiae, Pichia stipitis, Candida guilliermondii and Kluyveromyces marxianus. Nitrogen source, inoculum size and salt contents were examined.
Secondly, the study focused on the fermentation of hydrolysate from the green macroalgae Ulva rigida, confirming the possibility of converting algal hydrolysate into bioethanol, without nitrogen enrichment and sterilization. It was observed that pH regulation and aeration were not essential for the ethanol production. In these conditions, the experiment gave a concentration of 12 g L-1 and the conversion rate of glucose into bioethanol reached 82%. For the lab-scale assays, the media volume varied between 250 to 1 500 mL.
Finally, the scale up process was examined on a pilot scale (77 L) using S. cerevisiae growing on a hydrolysate of Chaetomorpha sp. This experiment gave a concentration of 5.6 g L-1 (lower than the results obtained during previous tests because of the limited hydrolysis yield), but with an efficiency of 97%.

  • Title:An Enolate-Mediated Regioselective Synthesis of 1,2,3-Triazoles via Azide-Aldehydes or Ketones [3+2]- Cycloaddition Reactions in Aqueous Phase
  • Time :

Abstract

Objectives: We present a ‘greener’ synthesis for the direct conversion of arylazides into the corresponding trizoles
via phase transfer catalyst-assisted [3+2] cycloaddition in aqueous phase.
Methods: The synthesis of triazoles were approached (Figure 1) based on previously published methods for azide- aldehyde [1] and azide-ketone [2]. In an ordinary glass tube equipped with a magnetic stirring bar, to aldehydes or ketones (0.21 mmol), TBAHS (0.042 mmol) and KOH (0.42 mmol) were added successively in Milli-Q water (1 mL) at RT. Finally, corresponding arylazide (0.21 mmol) was added to above RM. This RM was stirred at RT for 2 minutes which was subsequently heated for 24 h to 48 h at 100 °C. The reaction progress was monitored by TLC and after consumption of starting aldehyde/ketone, RM was cooled to RT. The crude RM was extracted with ethyl acetate and it was dried over Na2SO4, filtered and concentrated. Product 3 was obtained by column chromatography and characterized by using NMR and MS.
Results: Present synthetic approach covering a structurally diverse group of aryl azides 1(a-e) and aldehydes 2(a-b) or ketones 2(g–n) to obtain high yields of varieties of triazoles. In addition, the excellent yields are even more impressive considering that water was the only solvent. Overall, our methodology has proven robust and demonstrated by the preparation of twenty-seven different triazoles, fourteen of them reported for the first time.

Conclusions: We have developed a simple, versatile, and green route for enolate-mediated azide-aldehyde or ketone [3+2]-cycloaddition reaction which enables the synthesis of triazoles containing a variety of functional groups with excellent regioselectivity using water as the only solvent. This water-compatible and phase transfer catalyst- assisted catalytic synthetic approach which provides a stepping stone towards a greener organic synthesis in pharmaceutical industries.

  • Title:Quality Reference Values for Heavy Metals In Soils Developed from Basic Rocks under Tropical Conditions.
  • Time :

Abstract

Soil Quality Reference Values (QRV) refer to the natural heavy metal concentrations that is not influenced or is minimally influenced by anthropogenic activities. Such values are unique of each environment, and their extrapolation to different locations becomes inadequate. This research aimed to determine the natural concentrations of metals in soils (QRV) developed on essentially basaltic lithology and tropical conditions in the south of Brazil. Seventy-two soil samples from the Forest Conservation Areas in the west of the state of Paraná, Brazil, were obtained. The extraction and dosage of Ag, As, Ba, Cd, Cr, Cu, Mo, Ni, Pb, Sb, V, and Zn were carried out employing methods USEPA 3051a and ICP-OES. The QRV was set to 75th percentile of each element, from the detection and exclusion of the outliers. The natural concentration of all heavy metals was related to the geological context of the basaltic area in Brazil. There was no influence of the pedogenetic degree of soils on the natural heavy metal concentration. The only relevant process for reducing the natural heavy metal levels was the Fe and Mn oxide solubility promoted by hydromorphic conditions. Fe oxides had a significant role in the maintenance of structural and adsorbed heavy metal forms in soils. The results may help the research and monitoring of environmental heavy metals in soils developed from basalt under tropical conditions.

  • Title:Terpenes in Conifers Under Developmental and Environmental Stimuli
  • Time :

Abstract

Among a wide variety of natural compounds synthesized by conifer trees, terpenes seem to be the most important group of secondary metabolites. They are a vital part of constitutive or induced defense mechanisms to protect the plant from invading pathogens and herbivore. Furthermore, they can take part in chemo-ecological interactions with co-evolved insects, e.g. bark beetles. Some of terpenes are known to manifest antioxidant properties which may contribute to their role in overcoming oxidative stress. It has been also suggested that
volatile compounds such as terpenes can be involved in interplant signaling, especially concerning biotic or mechanical stress. Numerous studies have shown that abiotic and biotic stress factors such as drought, temperature fluctuations, air and soil pollution or pathogen attack may affect the biosynthesis and emission of terpenes, and the response may depend on the stressor type and stress intensity. Although the general composition of terpenes is characteristic for each species, it has been shown that it can even differ between two individual trees, depending on tree chemotype. Despite many comprehensive studies in this area, the role of terpenes in plants is not completely understood. Some of the available results are contradictory. Here we present an overview of recent literature in this area to systematize the observed changes in terpene quantity and quality in conifer trees. The study is focused on three most important forest-forming conifer genera of European temperate climate zone – pine (Pinus sp.), spruce (Picea sp.) and fir (Abies sp.) due to their high utility and wide range of occurrence. Moreover, we tried to shed light on a complex function of these interesting compounds in view of progressive climate change.

  • Time :

Abstract
Phthalates are the most common plasticizer compounds worldwide, providing flexibility to a wide array of plastic products. The inadequate disposal of these chemical residues causes their absorption and accumulation by plant species in contaminated environments. The absorption and accumulation of phthalates in the mangrove species Avicennia schaueriana (Acanthaceae) were monitored over one year. A total of 30 fresh and dried leaf extract samples were collected through the “serapilheira system”, in the Guaratiba Biological Reserve in the state of Rio de Janeiro, Brazil, in three different regions of the Guaratiba mangrove forest: A (fringe), C (basin), and E (transition). Samples were analyzed by gas chromatography coupled to mass spectrometry (GC-MS). Bis-tridecyl phthalate was the main contaminant detected, and bis- isobutyl phthalate and bis-2-ethylhexyl phthalate were the major metabolites of the butanolic fraction obtained from the liquid-liquid partition of the ethanolic leaf extract. The observed chemical profile was rich in secondary metabolites, predominantly lupeol and 𝛼-amyrin. Exposure to these contaminants presents several risks to human health. This is the first work to confirm how the mangrove pollution process, through the accumulation of plastic contaminants in sediments and water, can directly affect the plant species and their biosynthesis.

  • Title:On the Dynamic Mechanisms of Intense Rainfall Events in the Central Andes of Peru, Mantaro Valley
  • Time :

Abstract
The present study was aimed at analyzing the main atmospheric dynamic mechanisms associated with the occurrence of intense rainfall events above the Huancayo observatory (12.05°S, 75.32°W, 3313 m asl) in the central Andes of Perú (Mantaro valley) from January 2018 to April 2019. To identify the rainfall events, we used a set of instruments from the laboratory of physics, microphysics and radiation (LAMAR) composed by in-situ pluviometric observations, satellite remote sensing data (GPM), Cloud Radar (MIRA- 35c), Boundary Layer Tropospheric Radar (BLTR) and downscaling model simulations with WRF (resolutions: 18 km, 6 km and 2 km) and ARPS (0.5 km) models to analyze the dynamics of the atmosphere for the synoptic, meso and local processes that control the occurrence of these rainfall events. The results showed that all intense rainfall events are associated with the presence of thermal meso-scale circulations that transport moisture fluxes through passes with gentle slopes along both sides of the Andes. The easterly moisture fluxes come in from the South America Low Level Jet (SALLJ) and the westerly moisture fluxes from the Pacific Ocean. The arrival of these moisture flows to regions within the Mantaro valley depends on their coupling with the circulations at medium and high levels of the atmosphere. At the synoptic scale, the results show that the rainfall events can be separated into two groups: the first one associated with westerly circulations (WC) at the mid and upper levels of the atmosphere, generated by the weakening and eastern displacement of the anticyclonic Bolivian high-North east low (BH-NE) system, and the second associated with easterly circulations (EC) at the mid and upper levels of the atmosphere, generated by the intensification of the BH-NE system. The observed and simulated results showed that multicell convective systems of WC events are more extensive and deeper than EC events. This situation can be explained as the convergence of moisture fluxes from opposite directions occurred within the Mantaro basin for WC events. In contrast, for EC events, the convergence develops at the east Andes mountain range, following which the multicell storm system propagates westward, driven by easterly circulations. The EC events occur mostly in the summer months, while the WC events occur mostly in the autumn and spring months. Moreover, apparently the inertia gravity waves (IGWs) formed in the Amazon basin transport moisture and energy to the central Andes plateau and intensify the convection processes.

  • Title:On the Development Of a Simplified Model For Thermal Comfort Control of Split Systems
  • Time :

ABSTRACT
Despite split-type systems for cooling purposes became popular in countries such as China, Japan. India, Indonesia and Brazil, their use commonly promote high gradients of both temperature and air velocity in rooms which may cause considerable thermal discomfort. Hence, this work aims at developing a simplified thermal comfort index, based on temperature and air speed, in order to develop controllers for those types of air conditioning systems, replacing the traditional on-off temperature set-point control by an effective and inexpensive thermal-comfort based control. The work is focused on the assessment of comfort in classrooms by carrying out measurements according to ISO 7730 and ASHRAE 55 Standards, which defines the thermal satisfaction in occupied environments based on the PMV index. Specifically, the speed, temperature and relative humidity of the air and the mean radiant temperature of the room were measured at eight positions within the space. The field experiments were performed considering two 10.5-kW cooling capacity appliances installed in different positions relatively to the layout of the room, considering three levels of supply airflow (high, medium and low) and three set-point temperatures (23, 24 and 25 °C). An analysis of uncertainties is presented for PMV measurements and a regression analysis was applied to the measured data to determine a simplified correlation between thermal comfort (by means of the PMV index) air temperature and air velocity, aiming at developing afterwards a control device based on thermal comfort instead of temperature setpoint only. Results are shown in terms of distribution of air speed, air temperature and PMV index for the two configurations of equipment installation, as well as the resulting empirical model correlating thermal comfort index with both temperature and air speed. In addition, thermal comfort opinions from a survey are contrasted with the simplified thermal comfort model.

  • Title:The Self-assembly of Sepiolite and Silica fillers for Advanced Rubber Materials: The Role of Collaborative Filler Network
  • Time :

Abstract
SiO2-based nanofillers, commonly used to enhance the mechanical properties in tyres, favor a low hysteresis while maintaining sufficient reinforcement respect to the carbon black. However, a need remains to further reduce the rolling resistance of the tyres, and so to identify new fillers that allow a further improvement in the balance between hysteresis and reinforcement of materials. In this context, the present work aims at studying the self-assembly of two different white nanofillers, such as sepiolite and silica, and the role of collaborative filler network in rubber nanocomposites (NCs), considering that clay/silica hybrid systems could be a possible strategy to reduce the hysteresis of rubber materials, thanks to the potential synergistic effect between isotropic and anisotropic fillers.
Thus, rubber NCs containing silica and different kind of sepiolite were prepared by combining latex compounding technique (LCT) and melt blending. Highly filled NR masterbatches (MBs) were firstly prepared by coagulating natural rubber (NR) latex and sepiolite aqueous suspension, and then mixed with NR rubber matrix together with silica filler, silane coupling agent, vulcanizing agents, and antioxidants. An exhaustive morphological, rheological, and dynamic-mechanical analysis demonstrates that the use of double white fillers, having different aspect ratios, allows to obtain a good trade-off between efficient reinforcement and low Payne effect. These results have been ascribed to the formation of a cooperative filler network, deriving from the remarkable interaction of both fillers with the polymer, as assessed by morphological and spectroscopic investigations.
This study, even if referred to clay/silica double fillers, provides clear evidence of the significant role of self-assembly of hybrid nanofillers to produce a collaborative filler network and thus advanced rubber materials.

  • Title:Biodiversity of Collembola on Green Roofs: A case Study of Three Cities in Belgium
  • Time :

Abstract
Green roofs are often promoted as a mean to counter the negative environmental effects of urbanization on nature and to increase the amount of green space in cities. Green roofs often enhance aboveground biodiversity, especially herbivores and pollinators. However, if and in what way they support belowground biodiversity, and more specifically soil fauna, is rarely studied. Therefore, we evaluated the diversity of a dominant group of soil fauna, Collembola (springtails), on twelve extensive green roofs in three cities in Belgium (Antwerp, Ghent and Hasselt), over a one year period. The roofs differed in height above the ground, surface area, vegetation type, and age, i.e. time since construction. We analysed if these roof characteristics influenced species richness, abundance or diversity of Collembola. In total we found ten species of Collembola. Species richness was not higher on roofs that were larger (habitat area) or closer to the ground (isolation to surrounding soil), indicating that island-biogeographic theory is not applicable to species richness in our study system. However, significant differences in the mean number of individuals (abundance) were found between different months. Collembola taxonomical composition also varied between the roofs, but this variation could not be related to any of the measured roof variables. Roof communities were characterised by hemiedaphic life forms, preferring neutral to semi-moist conditions. Apart from the age of the roof that showed a positive significant impact on the abundance of Collembola present, our results suggested that the collembolan fauna showed no significant differences in abundance, species richness or diversity between roofs with different characteristics. However, we suggest that future studies are needed to investigate whether our findings are applicable to other groups of soil-living arthropods on green roofs.

Dr Jeffrey Jacobs Master of science: evolution en behavioural-biology
PhD Research project: Biodiversity on urban green roofs: a focus on macro-invertebrates
Hisresearch focuses on assessing the biodiversity on green roofs. Green roofs have potential for providing substantial habitat to plants, birds, and arthropod species that are not well supported by other urban habitats. Whereas the plants on a typical green roof are chosen and planted by people, the arthropods that colonize it can serve as an indicator of the ability of this novel habitat to support a diverse community of organisms.
In the first part of my PhD he focussed on belowground biodiversity, which was assessed for a deliberately chosen group of soil arthropods: the springtails (Collembola). Collembola are among the most abundant and widespread terrestrial arthropods, and are important in many soil functions such as litter decomposition and nutrient cycling. However, what explains their diversity and species composition in isolated, small habitat fragments is less known.
Furthermore, are we currently investigating multiple green roofs in the city of Antwerp (Belgium) and focussing on the aboveground macro-invertebrates that live on them (main focus wild bees). This research has the potential to contribute to the academic understanding of biodiversity on green roofs, but more than this, it may have an impact on wider society. With worldwide increasing urbanization it is crucial that we understand how we can counteract the loss of biodiversity in urban areas. Green roofs are seen as the number one method to get more green spaces in cities, however there is a lack of studies in Belgium on green roofs and how they can support biodiversity. We hope that by doing so we can derive main principles regarding the design of green roofs with the aim of maximizing their macro-invertebrate biodiversity.

  • Time :

Abstract

Microplastics are formed by the physicochemical breakdown of plastics. It is an alarming worldwide issue with long-lasting and hazardous effects. Natural expulsion of microplastics would take several years and it might also result in dangerous outcomes. To remediate these harmful microplastics several technological innovations were developed over the years. Among them, nanotechnological techniques have been investigated to a large extent for the remediation of microplastics. However, the production of nanomaterials using physical and chemical methods have been proven to be hazardous to the environment in several ways. Bio-nanotechnology is an alternative solution. Though it is a well-known and much investigated topic, it still remains primitive when it comes to microplastic remediation. Knowledge about the extensive possibilities of bionanoremediation would serve to be useful for the researchers to develop advanced eco-friendly strategies to control and eradicate the microplastics in a sustainable manner.

  • Title:Integrated Approach for Sustainability Assessment in Power Plant Projects using Building Information Modeling
  • Time :

Abstract

This research proposes a framework for sustainability assessment for power plant projects. The proposed framework integrates sustainability and Building Information Modeling (BIM) to achieve enhanced results concerning sustainability assessment in the power plants sector. International and regional sustainability rating systems as well as design guidelines are studied to develop a new sustainability assessment system dedicated to power plant projects. A total of 54 criteria, clustered in eight categories, are considered in the rating system. These categories are: 1) Nature and Urban 2) Site, 3) Energy, 4) Water, 5) Materials and Resources,
6) Emissions and Environment, 7) Operation and Management, and 8) Culture and economy. The sustainability levels are ranked in six levels: Non-Sustainable, Improved, Enhanced, Superior, Conserving, Restorative. The Analytical Hierarchy Process (AHP) is implemented to set the weights of the criteria that are considered in the proposed sustainability system. BIM is utilized to develop a plugin for the proposed rating system to determine the level of sustainability of power plant projects. The developed plugin invests the BIM model attributes to provide the stakeholder with an instantaneous sustainability metric tool that saves time and reduces the possible errors. A case study of a 100 MW power plant is presented to test the effectiveness of the developed approach in the sustainability assessment.

  • Title:Biochar and Hydrochar in the Context of Anaerobic Digestion for a Circular Approach: an overview
  • Time :

Abstract
Biochar and hydrochar are carbonaceous materials with valuable applications. They can be synthesized from a wide range of organic wastes, including digestate. Digestate is the byproduct of anaerobic digestion (AD), which is performed for bioenergy (biogas) production from organic residues. Through a thermochemical process, such as pyrolysis, gasification, and hydrothermal carbonization (HTC), digestate can be converted into biochar or hydrochar. The addition of either biochar or hydrochar in AD has been reported to improve biochemical reactions and microbial growth, increasing the buffer capacity, and facilitating direct interspecies electrons transfer (DIET), resulting in higher methane (CH4) yields. Both biochar and hydrochar can adsorb undesired compounds present in biogas, such as carbon dioxide (CO2), hydrogen sulfide (H2S), ammonia (NH3), and even siloxanes. However, an integrated understanding of biochar and hydrochar produced from digestate through their return to the AD process, as additives or as adsorbents for biogas purification, is yet to be attained to close the material flow loop in a circular economy model. Therefore, this overview aimed at addressing the integration of biochar and hydrochar production from digestate, their utilization as additives and effects on AD, and their potential to adsorb biogas contaminants. This integration is supported by life cycle assessment (LCA) studies, showing positive results when combining AD and the aforementioned thermochemical processes, although more LCA is still necessary. Techno-economic assessment (TEA) studies of the processes considered are also presented, and despite an expanding market of biochar and hydrochar, further TEA is required to verify the profitability of the proposed integration, given the specificities of each process design. Overall, the synthesis of biochar and hydrochar from digestate can contribute to improving the AD process, establishing a cyclic process that is in agreement with the circular economy concept.

  • Title:The Main Features of Global and Photosynthesis and its Evolution in the Global Carbon Turnover
  • Time :

Abstract
From the point of a new model of global carbon turnover photosynthesis and its evolution should be considered only in connection with geological processes on the Earth. Global photosynthesis is the main element of the global carbon cycle and is the result of activity of all living on the planet photosynthesizing organisms. First it was shown that the global photosynthesis can be described by the same equation as traditional photosynthesis. Final approximation of this equation can be expressed as follows
hv (CO2+H2O)atmosphere+hydrosphere → COM + O2 atmosphere
The role of biomass in it is played by buried organic matter which is transformed biomass of organisms lived in the past. Most of the global photosynthesis features also similar to those of traditional one. According to the equation, the reaction substrate, concentration of CO2 in the environment, is inversely proportional to the reaction product, atmospheric oxygen concentration, whereas the reaction products, atmospheric O2 concentration and analog of biomass, the rate of accumulation of buried organic matter are proportional. The analysis shows that global photosynthesis has all the features of traditional photosynthesis, except the ability to ontogeny. Like traditional, global photosynthesis has photoassimilation and photorespiration. The amount of synthesized biomass depends on the CO2/O2 ratio in the environment. CO2 concentration growth in the environment provides increasing assimilation and biomass growth, O2 concentration growth stimulates photorespiration and reduces the biomass growth. Global photosynthesis has the ability to fractionate carbon isotopes. Increased assimilation leads to the enrichment of biomass with the 12C isotope. Increased photorespiration enriches biomass with 13C isotope. Cyclicity is the main feature of photosynthesis evolution. It is the result of its participation in orogenic cycles that ultimately arise due to the gravitational influence of celestial bodies on the earth’s orbital motion around the sun. This affects magma convection causing lithospheric plates’ motion. Moving plates collide and evolving energy initiates thermochemical sulfate reduction which oxidizes sedimentary organic matter. Resultant CO2 fills “atmosphere hydrosphere” system and stimulates photosynthesis. Subsequent development of photosynthesis reduces CO2 concentration and evolves O2. These sequence of events results in climatic and biotic turnover. All the sequence of events composes the orogenic cycles and ends with mass extinction of organisms. The participation in orogenic cycles provided repeated combination of CO2 entry and subsequent developing photosynthesis which completed by abrupt dramatic change for another cycle. Multiple repetition of photosynthesis dynamics against the background of progressive and irreversible changes in the oxygenation of the environment led to the consolidation of the most important useful properties of living systems. On the other hand, it brought the whole system to a stationary state.

  • Time :

Abstract
Water has been regarded as one of most important resources in the industrial sector and plays a pivotal role in the hydrocarbon industry. With modern advancements in technology, enhanced agricultural production and urbanization, numerous regions across the globe are currently facing water stress. Coupled with rapid population growth and energy demands, it is imperative to understand the influence of water resources within the hydrocarbon industry and examine current water management strategies. It is a need of the hour to enhance current strategies to source water more efficiently, especially within water scarce regions such as the Middle East.
Unconventional resources have significantly contributed to the modern energy market. However, extraction of hydrocarbon from unconventional reservoirs is heavily water-intensive as compared to conventional reservoirs. This comprehensive investigation analyzes key design parameters that affect productivity within typical Middle Eastern shale gas reservoirs. In addition, simple constrained cases were constructed to better understand the influence of these parameters with respect to the overall production and water requirement. Furthermore, potential regional challenges along with resource management strategies are also highlighted.

  • Title:Increasing the Efficiency of Triangle Solar Thermal Collectors with Internal Cavity by using Turbulators with Different Shapes
  • Time :

Abstract
Sustainable energy technologies such as building integrated solar thermal systems may significantly contribute to the reduction of the greenhouse gases emissions by substituting a part of the fossil fuel used in buildings for space heating and domestic hot water preparation. Among these systems, solar thermal facades are good candidates when optimally oriented. Because the building facades are visible, the implementation of commercial solar thermal collector with rectangular shapes and dark colours may raise issues of architectural acceptance. To tackle these issues, non-rectangular (trapeze and triangle) solar thermal collectors with colored absorber plates (green, orange, red etc.) were developed in the Renewable Energy Systems and Recycling Research Centre of the Transilvania University of Brasov, Romania. The novel triangle solar thermal collector has an equilateral triangle shape, a small surface (0.06 m2) and non-dark colours (orange and green) allowing its integration in solar thermal facades with increased architectural acceptance and high coverage factor. Because of the small surface, the water circulates through an internal cavity beneath the entire absorber plate, instead of pipes as in the commercial solar thermal collectors having a significantly higher surface (around 2 m2). In the initial design of this novel solar thermal collector, a thickness of 20 mm resulted for the water layer in the internal cavity from constructive requirements. Indoor testing in standard conditions revealed color dependent efficiencies between 35 and 55%. To further increase the efficiency of the novel triangle solar thermal collector, an optimization process was developed by changing the water layer thickness and the mass flow rate. An absolute gain of 10.78% was obtained for the nominal efficiency and an average absolute gain of 10.35% over the entire range of inlet temperature by decreasing the thickness of the water layer to 5 mm while the mass flow rate was increased to
0.01 kg/s. In this paper, turbulators with various shapes installed in the internal cavity of the triangle solar thermal collector are considered to further improve its efficiency. The turbulators are modelled in SolidWorks and integrated in the 3D model of the triangle solar thermal collector. This 3D model is imported in Ansys Fluent for computational fluid dynamics simulations. The simulation results are comparatively discussed for the selected geometries of the turbulators. The influence of the shapes of the turbulators on the triangle solar thermal collector efficiency is analyzed.

  • Time :

Abstract
This research paper intends to review the mineral development and investment policies of Jordan. The formulation of mining policies that will attract foreign investment must address conventionally acknowledged investor concerns and some new challenges. Issues that have been extensively examined in the paper include country’s characteristics such as geological, political, financial, regulatory, operational, fiscal, social and environmental, and profit and marketing criteria. Once these criteria are analyzed for Jordan, they have been compared to the MENA region to provide insights of possible changes and improvements to both the MENA and Jordan mineral policy. For some time, Jordan’s mineral policies were not favorable for developing the country’s mineral sector, but mineral policies are now being changed to address aspects that need improvement. With better mining regulations in place; more efficient regulatory agencies; more liberal foreign investment regulations; a competitive tax system; upgraded infrastructure; a greater availability of excellent local expertise and skills; as well as a stable economic and political system, this will position the MENA countries as an excellent place to invest in mining and create more economic diversity for the whole region.

  • Title:Current State of Industrial Heating and Opportunities for Decarbonization
  • Time :

Abstract
In the United States, industrial emissions represent 22% of greenhouse gas emissions and are particularly hard to decarbonize, because (1) the processes emit CO2 as a byproduct of chemical reactions and (2) these industries require high-grade heat input. This study focuses on some of these industries, namely cement, lime, glass, and steelmaking. This work details the incumbent kiln and furnace technologies and explores the emerging processes with examples of existing projects that aim to reduce carbon emissions, such as carbon capture and storage (CCS), fuel switching, and other technological changes. We provide tools to evaluate the most appropriate low-carbon solutions at existing facilities and on new-build infrastructure while taking into account the local context and resources.
This presentation highlights one state within the U.S., California, as it has a high concentration of cement, lime, glass, and steelmaking facilities. The emissions from cement, lime, and glass facilities in California total 8.5 MtCO2eq/yr. About 6.3 MtCO2/yr (7.1% of in-state industrial emissions) could be captured from cement and lime facilities, transported, and stored in sedimentary basins below the Central Valley. Replacing 20% of coal by biomass could also reduce the fossil emissions by 0.5 MtCO2/yr (6.2% of in-state industrial emissions) without making changes to the facilities. As shown by this example, there are many strategies leading to the deep decarbonization of the economy and they need to be adapted to the local context.

  • Time :

Abstract
Poultry slaughterhouses generate an abattoir sludge (PAS) that needs proper management in the principles of circular economy and green deal goals that imply a net-zero emissions, more resource efficient and sustainable economy. This study proposes a waste-to-energy approach as a sustainable strategy for water heating by utilizing waste stream and internal usage in poultry slaughterhouse sector. In the study, energy crop Arundo donax (AD) biomass produced by irrigating treated abattoir waste water and solar dried PAS were used to produce bio pellet for the boiler heater. The solar dried PAS and grinded AD straw were extruded into pellets using a real industrial press at biomass combustion plants using i) 100% PAS:0% AD, ii) 50% PAS:50% AD, iii) 0% PAS:100% AD. The calorific value, bulk density, and energy density of the PAS, AD and PAS + AD pellets were in the range of 16.81-28.78 MJ kg-1 , 646-779 kg m-3 , and 10.86-22.71 GJ m-3 , respectively. Combustion image analysis results indicated the better flame richness and red color intensity of PAS + AD pellets than the both PAS and AD. Based on the results, almost 58% of the daily used fossil fuel coal for hot water production can be replaced by renewable PAS + AD pellets.

  • Title:Vertically Aligned CoMoS Nanosheet on PANI Nanowire as an Excellent Electrocatalysts for Water Splitting
  • Time :

Abstract
To achieve an efficient conversion of renewable energy sources through water splitting, low-cost, efficient, and eco-friendly catalysts are required for oxygen and hydrogen evolution. Here, we develop a vertically aligned cobalt molybdenum sulfide (CoMoS) nanosheets on a conductive polyaniline (PANI) nanowire on nickel foam (NF) by a one-step solvothermal synthesis. The macroporous nickel foam improve the carry of the O2 gas evolved, and vertically aligned CoMoS nanosheets on a three-dimensional PANI nanowire substrate form a hybrid architecture, promoting electrolyte penetration and the removal of gas bubbles, enabling firm touch between reactants and active sites, and generating smooth pathways for effective charge transport in the conductive channels. The hybrid CoMoS-PANI requires only 250 and 98 mV, to achieve a current density of 10 mA cm–2 in 1 M KOH, for the oxygen and hydrogen evolution reactions, respectively. As an electrode for overall water splitting, CoMoS-PANI/NF, as both the anode and the cathode, shows a current density of 10 mA cm–2 at a low cell voltage, 1.58 V. Moreover, it possessed excellent durability during the 50 h stability test, suggests that CoMoS-PANI is an efficient and stable bifunctional catalyst. The upgraded electrocatalytic activity of CoMoS-PANI can be attributed to the synergistic interaction between Co, Mo, S, and PANI. First, the CoMoS nanosheets were grown on conductive PANI nanowire substrate as hybrid architectures, encouraging electrolyte piercing and the removal of gases, enabling strong contact between and reactants and active sites, and creating a smooth pathway for effective charge transportion. Second, the defect rich structure, S vacancies centered in the CoMoS nanosheet structure, and amines in the PANI nanowire create a high electrochemically active surface area and a large number of active sites, expose active interfaces, and maintain the conductivity. Finally, the effective inter-electron transfer between cobalt and molybdenum and the intra-electron transfer between PANI and CoMoS reduce the kinetic energy barrier of initial water dissociation and ion adsorption. Thus, these factors resulted in excellent augmented performance for OER, HER, and overall water splitting. This work creates a promising step towards the synthesis of hybrid materials as excellent electrocatalysts for renewable energy generation.

Abstract
The European aquaculture industry began to undertake Atlantic halibut (Hippoglossus hippoglossus) aquaculture in the 1980s due to the favorable growth rate and high market value of this cold-water marine fish. Atlantic halibut cultivation began in Chile in 1996 in the Magallanes region (53 ̊S). Chilean aquaculture facilities were finally equipped to begin rearing Atlantic halibut after 12 years and a total investment of $ 2 million USD. Infrastructure is now in place to manage the entire production cycle, including broodstock rearing, egg incubation, larval rearing (yolk-sac stage, first-feeding), weaning, the nursery stage, on-growing in land-based tanks, harvest, and marketing. The hatchery phase to produce 10-g juveniles requires 10–12 months, followed by an approximately 30-month grow-out phase in land-based tanks to produce 3-kg fish. Further research and development are being performed in nutrition (diet formulation), genetics (selection for disease resistance and growth rate), fish health, and environmental issues to support the development of a sustainable marine aquaculture industry for this species.

Abstract
The development of long-term energy storage is more important today than ever because intermittent renewable energy source, such as wind and solar photovoltaic are growing rapidly in power generation market. Therefore, the demand on a bulk storage system is expected to increase significantly as result of renewable energy policy. The compressed air energy storage and liquid air energy storage system are an innovative technology for commercial grid scale energy storage. Especially liquid air energy storage system is expected to overcome the drawbacks of pumped hydro storage and compressed air energy storage. The proposed system is a novel stand-alone LAES system to enhance Round-Trip Efficiency (RTE) using a sensible heat store of packed bed type and latent heat store unit. The cryogenic Phase Change Material (PCM) melts at 110K based on experimental result, making it possible to provide cold enerrgy at a constant temperature for air liquefaction. The analysis shows that the implementation of energy recycling from the compressor and cold thermal store leads to a high RTE than conventional LAES system.

Abstract
The purpose of this study was to investigate the current epidemiology of DDH using a comprehensive nationwide survey in Japan. A questionnaire was sent to orthopedic surgeons in 1,987 facilities nationwide. A total of 783 (39%) facilities completed and returned the card of DDH. Of these, 79% reported no cases of DDH-related dislocation over the 2-year period, while the remaining facilities reported 1,295 cases.
The characteristics of children diagnosed with DDH-related dislocation were as follows: girls (89%), left side involvement (69%), bilateral involvement (4%), positive family history (27%), first-born (53%), and pelvic position at birth (15%). Seasonal variation showed an increase in DDH incidence among those born in the winter. Overall, 199 cases (15%) were diagnosed at >1 year of age, and these included 36 cases diagnosed very late, at >3 years of age. The majority of the 199 cases of late diagnosis had received earlier routine screening at <1 year of age. The characteristics of the children diagnosed with DDH nationwide were similar to past data from local regions. However, many children were diagnosed late (>1 year of age), particularly in the more populous regions. The findings identify a need for improved early routine screening for DDH in Japan.

Abstract

This work has been presented to develop a simulation model of 2D Lithium-ion Solid State Battery (SSB) for studying the thermal and electrical characteristics by varying the thickness of the electrode. This simulation model helps us to explore the cathode material characteristics to optimize lithium-ion SSB’s performance. In this paper, the simulation model has been formulated with 2D domain geometry and also encapsulated with variable parameters on a Multiphysics software. The electrochemical model was also formed with the help of mathematical modeling equations to obtain the rate capability of the li-ion SSB. This simulation model study shows the good thermal stability of the cathode material with a varied temperature range from 0⸰C to 150⸰C. Moreover, the electrical and electrochemical results also show good electrochemical reactivity, proper diffusion of li-ions, and good transport properties in the positive electrode of the li-ion SSB.

  • Title:Pyroprocessing and Reactivity of Saudi Arabian Red mud (RM) Waste for the Production of Sustainable Binders.
  • Time :

Abstract
The high embodied energy and Carbon emissions of traditional binders have led to a search for alternative cements. This paper explores the composition and reactivity of a red mud (RM) generated in vast quantities in Saudi Arabia, with a view to replace non-sustainable binders in construction.
RM waste is produced when refining bauxite for the production of aluminium. Previous authors estimate that 70-120 million tons of RM are generated annually, and stored on land or in the ocean near alumina refineries. In Ma’aden, current production is around 6,000 tonnes per day (over 2 million tonnes per year) which leads to long term disposal problems and land decommissioning costs. To date, due to its high alkalinity, only small quantities RM (3 wt.%) have been incorporated into Portland cement. However, the quantities need to raise to at least 5-10% for a worthy disposal option, and a viable option has not yet been found.
This paper studies the physical properties, composition and reactivity of the Saudi RM, and concludes on its possible application as a binder. The silica content and alkalinity are considered, as well as the specific surface area and composition which determine reactivity. According to the results, the RM presents abundant surface available to reaction, superior to commercial Portland cement and to other pozzolanic and supplementary cements such as FA and GGBS. The results also evidenced that gibbsite- Al (OH)3 , hematite -Fe₂O3 and cancrinite – Na₆Ca₂[(CO₃)₂|Al₆Si₆O₂₄]• 2H₂O are the main components of the RM, and that some Boehmite- ϒ- AlO(OH) is also present, inherited form the parent bauxite. The high alkalinity and temperature of the Bayer process have transformed the original kaolinite into cancrinite. The phase transformation of the RM resulting from the pyroprocessing at several temperatures are determined with X-Ray Diffraction analyses. The paper explores the evolution of the crystalline phases and their reactivity based on the setting and strength development.

  • Title:Subcritical Nuclear Reactor Driven by ion Beams
  • Time :

Abstract
The performance of subcritical nuclear reactors driven by proton and ion beams (accelerator driven system- ADS) is analyzed and the advantage of ion beams is substantiated. The conditions which maximize the power production and the energy gain G (defined as the ratio of the power produced to the power spent for the beam acceleration), ensuring in the same time a safe exploitation are identified.
With a proper choice of the target G of 20-30 can be obtained.
The particle fluence and the energy released are obtained through simulation with Geant4. The power spent to accelerate the beam is calculated by scaling from the data about the accelerator efficiency for a reference particle.
Cylindrical targets with rods of solid fuel (metallic alloy, oxide, carbide) in a bath of coolant are considered. The most significant influence on the energy released demonstrates the material used for the converter. The use of light materials increases the energy released especially for light ions at low energy. The best results are obtained with Be converter with length 100-120 cm.
The value of the criticality coefficient keff must be chosen as high as possible to maximize the power produced, but low enough to ensure a safe functioning of the reactor. The reactivity changes during various accident scenarios were analyzed in order to identify possible positive reactivity insertions. A value of 0.985 for keff ensures enough safety margin.
The results obtained with protons and ions beams from deuteron to 20Ne and energies from
0.2 to 2 AGeV, accelerated in a linac and interacting in U-Pu-Zr target with Be converter and keff 0.985 are presented. The beam intensity is 1.25‧1016, and the linac efficiency 0.18 for protons (values taken from the European Spallation Source project).
The optimal energy for proton is 1.5 GeV, with a G of 10 and net power Pnet of 150 MW. G 2-3 times higher can be realized with ion beams. With a beam of 7Li with energy 0.25 AGeV one gets the same Pnet but with G of 18, and necessitates an accelerator 2.6 times shorter. At intermediate accelerator length beams of Li or Be are the best option (G 20-25, Pnet 350-400 MW). In an accelerator with the same length as for 1.5 GeV proton it is preferable to accelerate ions with higher mass (12C, 16O, 20Ne) getting a G~ 30 and Pnet~1 GW.

Abstract
Waste cooking oil (WCO) is generally considered a global waste but with prospective for secondary use such as fuels or chemicals. In the present work, functionalizing of WCO to polymeric surfactants through a cleaner approach with high emulsification ability for enhanced oil recovery (EOR) of fossil crude and enhanced biocrudes solubility in petroleum crudes is proposed. The influence of synthesis conditions (temperature, time and concentration of reactants) on intermediates and the resulting polymeric surfactants was investigated. Products were characterized by UV-Vis, 1H NMR, FT-IR, and DLS technique, and particle stability and Zeta potential were evaluated. The results showed the high stability of the fossil crude-surfactant-brine emulsion. The affinity of the polymeric surfactant for EOR under Danish reservoir was also investigated. It was observed that the IFT of brine-surfactant emulsion (31.35 dynes/cm) was reduced to almost half compared to neat saline water (68.82 dynes/cm), and that the viscosity of fossil crude oil in presence of polymeric surfactant was significantly decreased. Finally, the polymeric surfactant was employed to assess compatibility of hydrothermal liquefaction (HTL) and pyrolysis biocrudes with fossil refinery streams with an aim to promote their integration into existing refinery. Consequently, the correlation between compatibility and molecular structure was drawn based on the experimental investigation on miscibility studies. The results obtained during the phase behaviour and IFT studies showed the high emulsification ability of functionalized polymeric surfactant for the enhanced crude oil recovery at reservoir conditions. In conclusion, the study introduces the concept of reusing WCO as an ecofriendly polymeric surfactant for EOR and green fuel compatibility enhancer.

  • Title:Legacies on the ground. Assessing ancient plant management in the Lower Amazon
  • Time :

Abstract

Plant management and human development are entangled in Amazonia, where landscape transformations such as cultural forests and anthrosols are associated with archaeological sites. The highly fertile Amazonian Dark Earths (ADEs) are anthropogenic soils that figure as a major human footprint in Amazonian landscapes. Numerous ancient Tapajó settlements dated to the Late Pre-Columbian period (AD 1000-1600) within the Santarem region present ADEs. This paper presents the main results from an archaeobotanical study in three sites recovering a diversity of food and non-food plants through phytolith analysis in samples from domestic contexts and test pits profiles. Domesticates included maize (Zea mays), manioc (Manihot esculenta), and squash (Cucurbita sp.), whereas palms (peach palm/tucumã, açaí palm), tubers (Marantaceae) and fruit trees (Annonaceae, Burseraceae and Celtis sp.) were the main native plants recovered in samples from the three sites. These phytoliths and anthropogenic soils are addressed as legacies from past human plant consumption and assess ancient soil and vegetal management strategies.

  • Title:Food Loss and Waste in the Context of the Circular Economy: a Systematic Review
  • Time :

Abstract
About 30% of food produced globally is lost or wasted along the food supply chain. In this sense, the objective of this research is to identify and systematize scientific publications relating food losses and wastes with solutions based on the concept of circular economy. Through inclusion and exclusion criteria, 40 articles were identified, until April 2020, which were analysed using the StArt tool. The papers were analysed based on the five categories selected in this study: definitions of food losses and wastes, quantification of food losses and wastes, solutions for food losses and wastes, examples of circular economy, relationship between food losses and wastes circular economy and food. The publications on the theme are from 2011, being mostly reviews until 2018 and case studies in the last two years. Developed countries, mainly European, have more publications. It is worth mentioning that there is no specific concept for food losses and wastes, which makes it difficult to quantify. The concept of circular economy is more related in terms of reduction, reuse and recycling than the idea of a systematic change in the food supply chain. The need for future studies that associate food losses and wastes with the circular economy remains a global challenge, especially for developing countries.

  • Title:Regional Comparison on Energy Efficiency Drivers
  • Time :

Abstract
The impact of energy use on the planet is continuously increasing and stands as an unsolved problem. Energy efficiency remains as the main mitigation factor to curb the growth of energy consumption and related CO2 emissions, arguably the major responsible for climate change. Understanding the driving forces behind efficiency change is therefore crucial for defining energy policies and examining sustainable development pathways. To this aim, we propose a pyramidal approach to progressively analyse and decompose energy intensity, the main global efficiency indicator, using the LMDI method. First, the effects related to supply and demand sides of the energy system are separated. Then, the supply side is further decomposed to reveal structural effects associated with transformation processes and fuel types. The approach is applied to developed (OECD) and developing (non-OECD) regions to provide meaningful analysis and comparison of past trends, which could shed light to future effective environmental actions. The results show that a significant decrease in the energy intensity of both regions has been driven mainly by widespread improvements in demand-side efficiency. Despite huge differences in 1990, rapid globalisation of enhanced conversion devices and passive systems across borders suggests future convergence between developed and developing regions. Regarding the supply side, unfavourable structural changes due to electrification have only been offset by transformation efficiency gains in developed countries. Consequently, emerging economies have worsened their energy sector efficiency as they thrive. Hopefully, they could take OECD’s achievements as a roadmap to decouple development trajectories from an inefficient electrification as soon as possible. Key strategies should address changes in fuel mixes, as they have generally contributed to energy intensity reductions mainly due to shifts from coal and nuclear power towards gas and renewable plants. The proposed methodology could help stakeholders to effectively analyse the energy system and to develop policies to reduce its environmental impact.

  • Title:Effect of Nitrogen Fertilization Associated with Vinasse and Biochar on the Dynamics of the Microbiota and N2O Emission in Soil Under Energy Cane Cultivation
  • Time :

Abstract
In the face of world pressure, the Brazilian sugar-energy sector has been optimizing and using more sustainable agricultural practices. Among them is the planting of new varieties, such as energy cane, i.e., hybrids of Saccharum spp. used for biomass production, showing higher fiber and biomass content, less edaphoclimatic requirements, and more resistance to pests and diseases. In addition to the use of these new varieties, optimizing management practices that encompass the crop production cycle, such as the use of nitrogen fertilizers by the industry, is necessary for the efficiency of the system. These fertilizers are known to be responsible for N2O emissions. Plants use less than 50% of the applied fertilizer, so at least twice as much as it is necessary to be applied for crop growth and production, and what is not absorbed remains in the soil or gets lost into the atmosphere. The reuse of agro- industrial residues also is a major differential of the sugar-energy sector because it promotes cost reduction and prevents incorrect disposal. Biochar or pyrogenic coal are also possibilities besides vinasse and straw, already widespread. In this context, we will present a study that aims to propose mainly microbiological indicators as a function of energy cane response to nitrogen fertilizer doses and application of co-products from the sugar-energy industry (vinasse and biochar) to mitigate GHG of anthropogenic origin to reduce the contribution of agriculture to global warming.

  • Title:Modeling of the Dispersion of Pollutants in Porous Media: Case of a Landfill in Brazil
  • Time :

Abstract
Municipal solid waste (MSW) disposal systems are still a sanitary and environmental problem. The high concentration of toxic substances existing in liquids arising from the decomposition of waste, present a risk to human health and the environment. It is necessary to establish mechanisms to predict leachate dispersion in order to determine possible scenarios and control systems. This work investigates the dispersion of leachate from urban solid waste through saturated soil. The municipal landfill of Jacarezinho in Brazil is the focus of the study. The conceptual model was based on existing data from geology, hydrology, hydrogeology and leachate characterization. The codes MODFLOW and MT3DMS were used and the dispersion of chromium, copper, lead and zinc was simulated. Pollutant mass concentration fields were calculated in 1, 5, 10, 25 and 50 years. The results indicated that the pollutants could reach the Ouro Grande River, in a period of 5 years and the tributary in a period of 1 year of the initial generation of leachate. For the final period of the simulation, the tributary of the Ouro Grande River received copper and lead concentrations that exceeded the maximum values allowed in Brazilian legislation for the watercourse quality standard. It was concluded that the Jacarezinho landfill has the potential to pollute the surrounding soil and groundwater.

  • Title:Long-term Nationwide Spatiotemporal Changes and Trends of Freshwater Temperature in Japan (1982–2016)
  • Time :

Abstract
If the present rates of biodiversity loss continue, projections suggest that within 240 years Earth may face its sixth mass extinction. Because many fishes and amphibians, as well as crustaceans, mollusks, and other aquatic macroinvertebrates, are ectotherms, temperature is an important component of water quality that directly affects their growth rate and distribution Freshwater temperature is a physical water quality parameter of critical importance, and understanding the trends in freshwater temperature is important for identifying potential threats to the biodiversity of aquatic ecosystems.
We analyzed freshwater temperature data (based on “The Water Quality Survey of Public Water Areas” of the Ministry of the Environment) from 1982 to 2016 throughout Japan to better understand how waters are warming in Japan.
We used linear regression to determine the temperature change rate and Mann-Kendall tests to identify significant temporal trends in the annual maximum and mean temperatures. Among 11,240 monitoring sites screened, 159 with fewer missing values were selected for analysis.
On the basis of this analysis, we identified and ranked the sites showing significant temporal increasing or decreasing trends for future management. At nearly half (42%) of the analyzed sites, the annual mean freshwater temperature was increasing; thus, in the future, adverse impacts from warm temperatures may increase in those aquatic ecosystems. The temperature change rate of fresh water was higher than that of air, indicating that the observed increases in freshwater temperature were not due to atmospheric warming only. Among individual sites, the annual maximum freshwater temperature change rate ranged from -1.27 to 1.91 °C/decade, and the annual mean rate ranged from -1.13 to 1.28 °C/decade. Few other studies have reported decreasing temperatures for fresh water.
We expect our results will improve understanding of how freshwater temperatures are changing at a large scale, enhance understanding of human impacts on the aquatic environment, support effective management of ecosystems experiencing temperature changes, and help to minimize the loss of biodiversity over the next half century.

Abstract
Recently, floods are occurring more frequently every year around the world due to increased anthropogenic activities and climate change. There is a need to develop accurate models for flood susceptibility prediction and mapping, which can be helpful in developing more efficient flood management plans. In this study, the Partial Decision Tree (PART) classifier and the AdaBoost, Bagging, Dagging, and Random Subspace ensembles learning techniques were combined to develop novel GIS-based ensemble computational models (ABPART, BPART, DPART and RSSPART) for flood susceptibility mapping in the Quang Binh Province, Vietnam. In total, 351 flood locations were used in the model study. This data was divided into a 70:30 ratio for model training (70% ≅ 255 locations) and (30% ≅ 96 locations) for model validation. Ten flood influencing factors, namely elevation, slope, curvature, flow direction, flow accumulation, river density, distance from river, rainfall, land-use, and geology, were used for the development of models. The OneR feature selection method was used to select and prioritize important factors for the spatial modeling. The results revealed that land-use, geology, and slope are the most important conditioning factors in the occurrence of floods in the study area. Standard statistical methods, including the ROC curve (AUC), were used for the performance evaluation of models. Results indicated that the performance of all models was good (AUC > 0.9) and RSSPART (AUC = 0.959) outperformed the others. Thus, the RSSPART model can be used for accurately predicting and mapping flood susceptibility.

  • Time :

Abstract
In this paper, ZnO nanoparticles (NPs) have been synthesized using extract of leaves of Azadirachta indica (Neem tree), Ficus benghalensis (banyan tree) and Tabernaemontana divericata (Chameli). These green synthesized NPs have been studied for anticancer and supercapacitor applications. The synthesized NPs have been characterized using various techniques such as UV–Visible spectroscopy, FTIR, powder x-ray diffraction (PXRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), field emission scanning electron microscopy (FE-SEM). The green synthesized nanoparticles with Azadirachta indica have been used to investigate the cell viability of human lung adenocarcinoma (A549 cells) using MTT assay. Herein, a comparative anticancer study has been performed using only leaves extract of Azadirachta indica, ZnO NPs synthesized with leaves extract of Azadirachta indica and chemical-wet method respectively. The viability of lung cancer cell lines (A549) decreases significantly with ZnO NPs synthesized with leaves extract as compare to only extract (OE) of leaves of Azadirachta indica (Neem tree). The cell viability does not changes with concentration of ZnO NPs synthesized with chemical wet method. So, the ZnO NPs synthesized with chemical-wet method has been used as a control for this anticancer activity. The cell viability also decreases with an incubation period of 48 h at the concentration (100, 150, 200 and 250 µg/mL) of ZnO NPs. The IC50 value for zinc oxide nanoparticles prepared with 1 mL of leaves extract (L1-NPs) has been obtained 138.50µg/mL at 48 h incubation. Herein, the flow cytometry study has also been performed. The ZnO NPs synthesized with leaves extract of Ficus benghalensis (banyan tree) and Tabernaemontana divericata (Chameli) have been studied for supercapacitor applications. The specific capacitance (Cs) has been determined using cyclic voltammetry (CV) technique. Herein, the calculated values of specific capacitance for ZnO NPs synthesized with Ficus benghalensis (banyan tree) are 6.318 F g-1 at 20 mV/s, 4.363 F g-1 at 40 mV/s, 3.611 F g-1 at 60 mV/s, 3.222 F g-1 at 80 mV/s and 2.972 F g-1 at 100 mV/s respectively. Similarly, the specific capacitance have been calculated using glassy carbon electrode (GCE), which has been drop casted by ZnO NPs synthesized with Tabernaemontana divericata. Herein, the calculated values of specific capacitance are 535.7142 F g-1, 401.7857 F g-1, 304.7619 F g-1, 229.9107 F g-1 and 189.2857 F g-1 respectively. Herein, the highest energy density and power density have also been determined 36.4583Wh/kg and 65.6249W/kg respectively at 20 mV/s. Whereas, the values of highest energy density varies in the range from 1.0620 Wh/kg to 0.4996 Wh/kg for ZnO NPs synthesized with Ficus benghalensis. It means, the ZnO NPs synthesized with Tabernaemontana divericata can be used as an electrode material for high performance supercapacitors and ZnO NPs synthesized with leaves extract of Azadirachta indica can be used as nanomedicine for lung cancer.

  • Title:Heat Transfer Enhancement and Optimization Analysis of Energy Storage Based Solar Thermal Collector
  • Time :

Abstract
The application of solar water heating systems (SWHs) has attracted many attentions in recent years. The main component of a SWH system is the solar collector, and among various types of solar collectors, heat pipe evacuated tube solar collectors (HPETCs) are widely used. However, due to the intermittency in solar intensity, the HPETCs may not work at their maximum functionality. In this study, performance optimization of an HPETC integrated with phase change materials (PCMs), is investigated under normal and on-demand (stagnation) operations via computational fluid dynamics (CFD) modeling. In phase-I, the effect of heat pipe position on the overall performance of the collector is investigated. The results from phase-I show that the phase change process of PCM was expedited by 48 minutes under on-demand operation, for the collector with heat pipe in center, compared with conventional system (heat pipe at top), where in normal operation, the thermal energy storage enhancement is achieved, for the collector with heat pipe in center, by 24% increase in PCM’s melting fraction . In phase-II, the effect of various types of PCMs are investigated, where tritriacontane paraffin, xylitol, and erythritol are selected. In normal mode, the maximum exhibited total energy storage of 295.39 kJ/kg was acheived for paraffin tube, however, the fin temperature of xylitol tube was around 10 °C higher compared with the other tubes throughout the day. In on-demand operation, the maximum energy storage of 413.15 kJ/kg was achived for erythritol tube, however, the paraffin tube shows fin temperature difference of 14 °C compared with other tubes. Consequently, utilization of dual PCM of paraffin/xylitol in normal and paraffin/erythritol in on-demand operations is recommended to enhance system’s thermal performance. The results from this study can be a benchmark for further optimization of HPETCs in thermal energy storage systems.

  • Title:Water Management for Improvement of Rice Yield, Appearance Quality and Palatability with High Temperature During Ripening Period
  • Time :

Abstract
Rice (Oryza sativa L.) is one of the world’s most important food crops and is a staple food in Japan. In recent years, decreased yield and deterioration of appearance quality and palatability due to abnormally high temperatures during the ripening period have become serious problems for rice farmers in Japan. To clarify the optimal water management in large-scale fields under high temperatures at the ripening period, effective water management during this period for improvement of yield, appearance quality and palatability were investigated. Compared with intermittent irrigation and flooded irrigation, the soil temperature with saturated irrigation remained low throughout the day, and the decrease rate of the bleeding rate of hills was the lowest. These results suggested that the saturated irrigation maintained root activity. For the three irrigation types, the number of spikelets per m2 and 1000-grain weight were similar, however, saturated irrigation resulted in significantly higher rice yield due to improvement in the percentage of ripened grains. The saturated irrigation produced a high percentage of perfect rice grains and thicker brown rice grain, furthermore, the palatability of cooked rice was excellent because protein content and hardness/adhesion ratio were both low. Thus, under high-temperature ripening conditions, soil temperature was lowered and root activity was maintained when applying saturated irrigation after heading time. The results indicated that saturated irrigation is an effective countermeasure against high-temperature ripening damage.

Abstract
Water scarcity is one of the biggest threats of the climate change, specially in mediterranian region. The higher the temperatures the lower the rainfall and the effects of water scarcity are already a problem. More over, the biggest economic sector in mediterranean region is toursim and has a high water footprint, between 3 and 5 times higher than local hauses.
Circular economy practices apllied in hotels could help in facing the water scarcity. It consists in treating the water in the same hotel for their reutilization (decentralized systems). There are several option to apply circular economy of water in hotels. One of them is vertECO a nature based solution that has been demonstrated technically and economically feasible to aply in hotels.
The treated water meets with all the europaean legislation for treated water reuse and the pay back period for a hotel of 440 rooms is 5 years if the water price is 3 € per cubic meter. If we consider also co benefits the pay back period is even lower.

  • Title:Sustainability for Drinking Water Reservoirs: Central Softening and Floating Solar panels
  • Time :

Abstract
Drinking water utilities in the Netherlands aim to reduce the CO2 footprint in order to become CO2 neutral in the coming years. A preferred route to achieve this is by reducing the CO2 footprint in the primary drinking water production processes. This can be done by using more sustainable chemicals, recycling residual/waste streams and by modifying the production process, for example by applying central softening.
We recently published a paper in which we demonstrate that central softening in drinking water production leads to a net reduction of the carbon footprint. The full life cycle assessment shows that the detrimental contributions to the carbon footprint, due to the use of chemicals and energy for central softening, are outweighed by the beneficial contributions at the household level, where reduced scaling leads to prolonged lifespan of appliances, reduced energy consumption and reduced use of cleaning agents. We estimate that the net total carbon footprint of drinking water softening in the Netherlands is around -0.11 Mtons CO2 equivalent per year.
Nevertheless, CO2 neutrality cannot be achieved by only focusing on reduced emissions in the primary production processes. Part of the CO2 footprint reduction needs to come from compensation, one way to achieve this is by employing floating solar panels. However, little is known on the effects of floating solar at large scale on water quality and ecology. We therefore designed a floating solar pilot and installed this on one of the water reservoirs (depth <4m) at Evides Water Company, a company based in the south of the Netherlands. Evides relies mostly on surface water for the production of drinking water, and river water is stored in large reservoirs. Several quality parameters have been monitored over multiple years, which include: 1) physico-chemical (oxygen, temperature, organic carbon, heavy metals, etc.), 2) microbiological (fecal bacteria) and 3) (hydro)biological (birds, water plants, plankton.

  • Title:Native Species are at Risk by the Metal Deposition in the Brazilian Atlantic Rain Forest.
  • Time :

Abstract
Trace metals adsorbed to particulate matter are supposed to be increasingly incorporated into the remnants of the Atlantic Forest next to urban, industrial, agricultural and mining sources of air pollution, especially in the Southeastern Brazil. They can be retained on tree canopies through dry and wet deposition and incorporated directly into the soil by deposition or indirectly by litterfall and decomposition. Some native tree species are better suited than others to offer a realistic overview of metal accumulation in a forest ecosystem due to their higher accumulating capacity within or on their leaf tissues. To assess the capacity of trees in different successional stages to accumulate metals, we conducted a passive biomonitoring with pioneer (P) and non-pioneer (NP) species, soil and litter in two fragments of rain forest located in São Paulo – Brazil (PP-peri-urban) and (PEFI-urban). We sampled leaves of trees, soil and litter in both sites, during the winter of 2015, and analyzed the concentrations of metals by ICP-OES. In general, NP species have higher leaf concentrations of most of the elements and higher mobility ratios for Cr, Fe, Mn, Ni, Pb and Zn were higher in NP plants than in P species in both sites. Mn concentrations were stocked in litter and could be associated to the low bioavailability of this element caused by the effect of the metals to the decomposing organisms. These results allowed us to conclude that NP species were more susceptible to the metal contamination, since the concentrations of the elements studied were higher than in P species. Even though PP site is located far from the urban emissions, the deposition of metals also impacts the site.

  • Title:Use of Real Options to Enhance Eater-energy Nexus in Mine Tailings Management
  • Time :

Abstract
Mine tailings are waste obtained after processing mineral ore to acquire element(s) of interest. They are a mixture of ground rocks with process effluents. The largest water sink at most mines is the tailing storage facility and inappropriate management of water content in mine tailings can become a threat to its stability, and consequently, its environmental safety. Also, for reasons pertaining to water scarcity, water reuse and recycling is a plausible option to mining companies. Proper handling of mine tailings and water supply management can considerably improve the water-energy nexus. In this article, we evaluate the water-energy nexus in copper mining companies using a water reduction model focused on mine tailing facilities and water supply to the mine site to find the trade-offs between water and energy. To find out about the economic outcomes of the options covered by the analysis, project valuation techniques with a real options approach are used. This approach deploys Monte Carlo simulation to perform sensitivity and uncertainty analysis to evaluate every cost component of each water management strategy. Results show that where seawater is supplied to the mine site, improving the reuse of water by using dewatering technologies will improve the water-energy nexus. Even though the costs of these technologies are elevated in comparison to traditional disposal method because they are energy-intensive, the reduction of water requirements in the mine will reduce the cost of its treatment and transport which accounts for a large proportion of the total cost.

  • Title:Application of Bioremediation in Geotechnical and Geo-environmental Engineering
  • Time :

Abstract
Bioremediation has been applying in both geotechnical and geo-environmental engineering since few decades ago. While bioremediation has been using to prevent erosion and slope stabilization in geotechnical engineering, bioremediation process has been successfully using in remediation of contaminated lands. Bioremediation is using living things to eliminate or reduce environmental contamination such as contaminated soils or groundwater. Some microorganisms are able to change these chemicals into harmless stage. These microorganisms that live in soil and groundwater naturally consume certain chemicals that are harmful to people and the environment. Plants such as vegetations can also be used to clean up soil, water, or air; this process is called phytoremediation. As the large numbers of organic contaminants can be degraded by micro-organism and most biological treatments attempt to optimize conditions for degradation by the naturally occurring indigenous microbial population. Biological degradation processes can be either in situ or ex situ and aerobic or anaerobic (Wood 1991). Most methods of bioremediation involve supply of oxygen, foods and nutrients required by the micro-organism. This lecture present two selected bioremediation methods which were invented to use in geotechnical engineering and geo-environmental engineering. The one developed to use in geotechnical engineering is Soil Nail and Root System in which a long root grass is used to stabilize surficial slip of soil mass in conjunction with nail system which was used for stabilizing deep slip. In this process, grass roots provide reinforcement strength to the soil mass within the shallow zone in addition to the additional strength provided from suction activity of root system. This has long been used in Ontario, Canada to stabilize steep slopes along the rivers. Second one is in trial stage in which petrochemical contaminated soil was remediated using the micro-organism which eat diesel naturally. These specific micro-organisms which could consume more petroleum hydrocarbons were bred in the contaminated soil to eliminate the contamination in the soil. Their travelling speed and distances were enhanced by applying electrokinetic flow which carry them to further distance Hassan et.al (2016). In addition, foods and nutrients required by them were transported with the help of electrokinetic flow.

  • Title:Co-existence and Co-prosperity between Offshore Wind Farms and Fishermen
  • Time :

Abstract
In order to reduce carbon emissions and achieve a nuclear-free homeland, the Taiwan government revised the “Guidelines on Energy Development” in 2017 for its energy transition. By 2025, renewable energy is expected to reach 20%, with offshore wind power of 4.2 GW, an estimated power generation capacity of 14 billion kWh, and an annual carbon reduction of 7.1 million tons. However, among the 36 planned offshore wind farms in Taiwan, 21 are off the coast of Changhua. This is an important fishing ground for the coastal fishery industry and a production base for aquaculture in shallow marine water. Offshore wind farms are bound to affect the livelihood of fishermen. Therefore, through the co-existence and co-prosperity between wind farms and fishery, the conflicts in sea area utilization can be solved by marine spatial planning (MSP) and integrated coastal zone management (ICZM).
It is worth the time to think about how to use the idle sea areas between offshore wind turbines. Sea areas in wind farms may be efficiently used if marine ranches and cage culture can be planned based on the concept of integrated multi-trophic aquaculture (IMTA). Therefore, on the premise of investments in cage culture, this study evaluated the marine environment, biological resources, hardware settings, legal norms, and economic feasibility of the predetermined area of Phase 1 wind power plant off the coast of Changhua, Taiwan. According to the results, round cages could help reduce the impacts of ocean currents and tides, and 16 cages placed in sea areas among four wind turbines could achieve economic scale and remarkable fishery benefits without affecting the safety of wind turbines. If fishes with high economic values are cultured in cages and species from various trophic levels, such as seaweed and shellfish, are produced, then this can reduce impacts on the overall environment and help increase the values of fishery resources, so that the sea areas for offshore wind power can be sustainably operated.
Taiwan’s coastal fishery industry is declining day by day. While wind farms are in conflict with the industry, it can be a turning point for fishermen. It is better to teach someone to fish than to give him a fish. Measures, such as proper compensation mechanisms, a friendly adjustment on fishery management, and sound fishing village development, can aid in the co-existence and co-prosperity between wind farms and fishery after energy transition.

  • Time :

Abstract
Recently researchers have focused to enhance the electrocatalytic activity of the biosystems, increasing the energy generation and electronic conductivity into the biofilms. Enzymes immobilized onto the surface of electrodes in biological fuel cells has been extensively reported. A biofuel cell provides a means to obtain clean, renewable energy and have great potential to be used as alternative energy source for low power devices. Some important development to obtain the maximum energy from the fuels are the focus of this presentation. To enhance the power density of enzymatic biofuel cell (EBFC) it is necessary to deep oxidize the fuels, that is to say that all the electrons from the fuel must be removed. There are two main routes to obtain this (i) immobilization of a group of target enzymes to perform a cascade in order to maximize the fuel oxidation; (ii) development of hybrid biofilms employing a mixture of organic catalyst or noble metals nanoparticles with an enzyme able to break C-C bonds. We will present recent configuration to complete oxidize ethanol (ET) and ethylene glycol (EG) into CO2.

  • Title:Variability of Spatiotemporal Distribution Pattern in Response with Environmental Factors of Greater Amberjack Seriola dumerili in the Taiwan Strait
  • Time :

Abstract
Environmental characteristics in the Taiwan Strait (TS) have been linked to variations in the abundance and distributions of Greater amberjack (Seriola dumerili) populations. Greater amberjack is a commercially and ecologically significant species in ecosystems, and their spatial distribution patterns are a pivotal role in fisheries management and conservation. The purpose of this research was focused on modeling the spatiotemporal distribution pattern of S. dumerili in association with environmental factors, as well as its effects in the TS, which are still understudied. Therefore, the relationship between the catch rates and the influence of environmental changes on fish communities must be thoroughly investigated. To investigate the catch rates of S. dumerili with changes in oceanographic conditions within the TS, we applied generalized additive models (GAMs) to spatiotemporal fishery data from logbooks and voyage data recorders from Taiwanese fishing vessels (2014–2017), and we developed a species distribution model based on the best selected GAMs. The deviance explained (DE) indicated that high catch rates revealed that sea surface temperature (SST) was the most important factor influencing S. dumerili distributions, whereas mixed layer depth (MLD) was the least relevant factor. The model predicted that the S. dumerili would have a relatively high abundance of catch rates in the northwestern region of TS during summer, which would have extended to the coastal seas of mainland China, and that, despite having a comparatively higher catch rate would be widely distributed again in the winter. The targeted species were strongly influenced by biophysical environmental conditions, and the potential fishing areas have occurred along the waters of TS. The findings of this study were informative in determining how the S. dumerili responded to spatiotemporal environmental variables and predicting species distributions. Habitat preferences and distribution pattern of S. dumerili is the primary information that contributes to better knowledge and understanding of the environmental conditions of TS, which plays an important role and inform future priorities for conservation planning and management aspects.

  • Title:Application of Response Surface Methodology to Optimize Removal Efficiency of Water Turbidity by Low-Cost Natural Coagulant (Odaracha soil) from Saketa District, Ethiopia.
  • Time :

Abstract
Turbidity removal is a meaningful activity in the water treatment system, and it is an indicator of water quality. With this, natural coagulants are desirable and economical ways of removing water turbidity. The purpose of this study was to investigate the turbidity removal efficiency of Odaracha soil from river water. A coagulation experiment was carried out using a standard procedure for a jar test. 300 mL of water sample was added into a beaker by adjusting the water pH to the desired value. Different coagulant doses are added and mixed for 2 minutes by 250 rpm, then agitated for 10 minutes by 45 rpm. Finally, the sample was unflustered for different settling times. Response surface methodology (RSM) was also applied to optimize the process and estimate the interaction influence of the operating variables. According to the experimental result of this study, at the optimum condition (pH 7, 0.5 hrs. settling time, and 3 g/L of coagulant dose), the turbidity removal efficiency of Odaracha was 88.13%. In contrast, the predicted turbidity removal efficiency was 90.54%, which indicates the consistency between the actual and the anticipated results. Correspondingly the R2 value (0.9922) confirmed a high correlation between the real and predicted values. Generally, the quadratic model’s actual and predicted results confirmed the turbidity removal capability of Odaracha and the significant effects of all the individual parameters and their interaction effects (except the interaction between the dose and settling time).

  • Title:Experimental Study on Heating Performance of a CO2 Heat Pump System for an Electric Bus
  • Time :

Abstract

The heating performance of a heat pump system for an electric bus by using carbon dioxide (CO2) as refrigerant in cold climate was investigated. The effects of the outdoor and indoor air temperatures, indoor air flow rate, compressor speed, and the opening step of electronic expansion valve on system performance are examined. The results show that at air temperatures of –20 °C/20 °C (an outdoor temperature of –20 °C and indoor temperature of 20 °C), the system had a heating capacity of 15.3 kW and a coefficient of performance (COP) of 1.78, which shows that the heat pump system for the electric bus can deliver satisfactory heating performance in a cold climate by using CO2 as refrigerant. The heating capacity and COP increased with the indoor air flow rate and decreased as the indoor air temperature increased. Compared with the indoor air flow rate, the optimum high pressure of the system was influenced more by the indoor air temperature. An equation was also derived to relate the temperature of CO2 at the outlet of the gas cooler with the optimum high pressure of the heat pump system for the electric bus, which can be used as the optimum high-pressure control algorithm to maximize the COP.

  • Time :

Abstract
Hydrochemical investigation of groundwater was carried out on the coastal aquifers of Ogun Waterside, Southwestern Nigeria. Groundwater samples were collected and assayed for physicochemical parameters during wet season (August, 2016) and dry season (March, 2017). The analysed data were further subjected to correlation analysis (CA), principal component analysis (PCA), hydrochemical facies and descriptive statistics. Results revealed that the groundwater is slightly acidic with fresh to saline character. The CA showed very strong associations between TDS, EC and Cl concentrations in both wet and dry seasons. PCA confirmed the main factor influencing the groundwater chemistry in the study area to be component I (salinity component). Piper plots also revealed that the aquifer is mainly of Na-Cl water type. Schoeller and Stiff diagrams showed that the groundwater comprises relative abundance of major ions in the following order: Na^+>K^+>Mg^(2+)>Ca^(2+) for the cations and Cl^->HCO_3^->SO_4^(2-)for the anions. Thus, the primary process influencing the hydrochemistry of the study area is saltwater invasion while mineral dissolution and rainwater infiltration play less significant roles. Most parameters fall within the permissible limit proposed by the World Health Organization (2011) and Nigerian Standard for Drinking Water Quality (2007). However, higher concentrations of chloride and bicarbonate ions observed towards the southern flank of the study area suggest signs of impairment. Assessment of the sampled water for agricultural purposes with respect to salinity hazard, Total Hardness (TH), percentage sodium (%Na) and Sodium Adsorption Ratio (SAR) revealed that the water is suitable for agricultural activities.

  • Title:Maximizing Nature Driven Legume Crop pollination and Pest Regulation for Improved Yields and Food Security in Changing African landscapes
  • Time :

Abstract
Legumes are among the most important food security crops cultivated by smallholder farmers and consumed for their proteins and other essential nutrients by millions of people, especially in sub-Saharan Africa. Most legumes depend on insect pollination and natural pest regulation for sufficient yields. However, there is emerging evidence that yield gaps caused by lack of pollination and pest pressure may be common. We undertook a systematic review of the literature to evaluate pollinators and natural enemies’ contributions to legume crop yields and the factors driving the diversity and efficiency of these beneficial organisms in changing African landscapes. Our review identified the critical role played by pollinators and natural enemies in legume crop production in Africa and the important contributions of these organisms to food security. The review found agricultural intensification and population growth as the key drivers changing the landscapes used by beneficial organisms and threatening their future existence. We propose the use of ecological intensification in safeguarding the legume pollinators and pests’ natural enemies. The application of ecological intensification through practices such as effective habitat management or establishment of boundary features, fallows, etc., in legume cropping systems, can restore or maintain semi-natural and natural habitats suitable for beneficial insects. These habitats provide the much-needed connectivity required by beneficial organisms within legume agricultural landscapes to sustain viable and ecologically functioning populations.
