  • Title:Antioxidant Properties of Lipolytic Enzymes as a New Instrument For Estimation The Effects of UV Radiatioa
  • Time :

Abstract

As is known, photochemical processes are accompanied by the formation of free radicals and reactive oxygen species (ROS), which give rise to a cascade of reactions ending under extreme conditions by unwanted disruption of the natural structure of the lipids (LPO) and protein, inactivation of enzymes and destruction of DNA, which together serves as a manifestation of oxidative stress. All compounds that reduce the concentration of unsaturated fatty acid hydroperoxides (UFAH) resulting from ROS action in the lipid phase, are antioxidants.
We are the first (Patent BY No. 019669), who used the increased sensitivity of phospholipase A2 (PLA2) to oxidized phospholipids compared to non-oxidized forms to estimate the degree of lipid peroxidation as a result of UV exposure ( = 180-400 nm). We have found that the system” PLA2 – hemoproteins – oxidized phospholipids“ allow to detect the total antioxidant activity of biological liquids. This is very important in terms of estimation adverse environmental effects on humans.

  • Time :

Abstract

This study investigates a dynamic model of Upflow Anaerobic Sludge Blanket (UASB) reactor for the effect of biological granule size on high-strength wastewater treatment. The model can also investigate the biogas production rate in bed and blanket zones of UASB reactor. Different amounts of methane gas are explored by methanogenic bacteria that can be used as a source of green energy. The simulation results indicate high COD removal of about 80% – 90% in UASB reactor as granule size declines to 1 mm. Moreover, the biomass concentration boosts to 90 and 25 kg/m3 in reactor bed and blanket zones, respectively as granule size declines to 1 mm at substrate concentration of 3 kg/m3.

  • 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.

  • Title:Increasing Industrial Productivity and Reduction of Vinasse Volumes of Fermentations with Recycling of Yeast Cells and High Ethanol Concentrations
  • Time :

Abstract

Industrial processes of ethanol production in Brazil are characterized by faster fermentations (6-10 hours), high concentration of yeast cells (8-15% v/v), recycling of yeast cells and an alcoholic content around 8.0% (v/v) which represents a production of 12.4 litres of vinasse per liter of ethanol produced. Increasing ethanol concentration in wine reduces vinasse volumes, saves steam in the distillation process and reduces water consumption per liter of ethanol produced. Moreover, the benefits of raising ethanol concentrations to industrial productivity may be as significant as the savings generated by reducing, transporting and applying vinasse in the field. Despite of these benefits, the increase of industrial productivity is not always evident due to other factors that affect the industry. In addition, ethanol content may affect the fermentation time and residual sugars in raw wine. The objective of this work was to evaluate the relationship between ethanol content and increase in industrial productivity, reduction of vinasse volumes, as well as, its impact on other indicators such as residual sugars in the wine and fermentation time in industrial scale. This evaluation was based on data analysis from Brazilian distilleries in the last five years. The results showed an increase in ethanol content of fermentations, which correspond to a significant reduction in vinasse volumes and higher industrial productivity. In one case study, it was observed a reduction of more than 300 million litres of vinasse by increasing ethanol concentration in wine. In another distillery for every 1% more of ethanol concentration, the mill produced 813,000 litres more ethanol per week, without significant residual sugars in wine (below 0.1% w/v). These results demonstrate the benefits obtained from increased ethanol concentrations in the wine at 12% (v/v).

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.

  • Time :

Abstract

Semiconductor Quantum Dots (QDs) with stable and wavelength-tunable photoluminescence (PL) are very promising emitters for various photonic and optoelectronic applications. Up to date, there are many synthetic protocols providing nanomaterials. In this study we applied the preparation in the liquid dispersion phase, which is a colloidal synthesis in an organic medium with the participation of surfactants. Environmentally friendly and commercially available substituted thio- [1] and selenoureas [2] in combination with well-known methods are suitable sulphur and selenium precursors for the highly reproducible synthesis and further large-scale production of ternary Cd-Zn-S(Se) QDs. This study was carried out to examine the mechanism of interaction between substituted thio- and selenoureas with metal carboxylates [3] under the influence of oleylamine, which was taken as a base in the synthesis of QDs. Also, the influence of substituents (aliphatic, aromatic and heterocyclic fragments) in substituted thioureas on the synthesis kinetics and optical properties of the resulting nanomaterials has been described. The homogeneity of the QDs elemental composition and uniformity in size and shape were confirmed by appropriate studies on these materials. It is also shown that reproducible synthesis with 24 times scaling (till 10 g) makes this approach very promising for the transfer to the industry. The findings of the study show that uniform and highly photoluminescent (photoluminescence quantum yield up to 67 %) can be easily transferred to industrial production, due to the high reproducibility and safety of the presented methods.

  • 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: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

  • 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.

  • Time :

Abstract

The urban hydrological cycle needs to be reestablished due to the effects it suffers from the anthropogenic activities (surface waterproofing, increased surface runoff, diffuse pollution, among others). Green infrastructure such as infiltration trenches, rain gardens, or pervious concrete is an excellent alternative to complement the hydraulic and environmental efficiency of urban infrastructure. Different studies analyze options to improve the quality of the water that is infiltrated through this type of infrastructure. The physical and chemical characteristics of the material selected for adaptation are essential to mitigate the infiltrated water’s polluting effect on the subsoil. This work presents a geochemical approach to the behavior of filter materials used in infiltration trenches and/or rain gardens. Samples of soil, sand, gravel, and volcanic slag used in this type of green infrastructure were analyzed to determine its decontaminating potential. Synthetic runoff water quality analyses were performed and X-ray diffraction and scanning electron microscopy on the filter materials (in the dry and saturated state, after infiltrating runoff water). To determine the materials’ geochemical behavior in contact with water, the software PHREEQCE was used. The water quality results were compared with national/international standards, while the change in its quality (before and after coming into contact with the filter materials) was observed through the geochemical interactions that occurred. The results showed the materials’ ability to remove pollutants through the formation of secondary minerals (rhodochrosite) and others’ precipitation (anglesite). However, it was also found that some minerals contained in the filter material, can solubilize ions that could be toxic to the environment. Therefore, this work highlights the importance of geochemically characterizing the materials before building green infrastructure.

  • 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.

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.

  • Time :

Abstract

The processes of abiogenic (water) migration of substances with gravitational moisture flows are studied based on information about the soil cover structure, as well as on a number of methodological principles: complementarity, consistency, agility and targeting of processes, structural organization of substances in space-time and filtration heterogeneity. Humification contributes to the formation of a repository of biological information and energy in soils and bottom sediments. Climatic conditions determine the creation and functioning of dynamic, non- equilibrium and self-organized systems of various genesis in the soils.
The aim of this research is to study the contribution of humic substances to metal migration, including radionuclides, at the border of bottom sediments and water flow.
During the experiment with addition of dissolved humic acid, the following was established. The introduction of organic carbon into the system with bottom sediments containing a significant number of radionuclides contributed to the transition of the sought radionuclides to a soluble state with a further release into the aqueous medium. This property was especially noted for such radionuclides as 152Eu and 241Am, the content of which, in the aqueous medium for 350 days from the experiment initiation and 333 days after the introduction of water-soluble organic carbon into the aqueous medium, was 198±8 Bq•L-1 and 167±7 Bq•L-1, respectively. The content of other radionuclides (40K, 60Co, 137Cs) was not so significant (Bq•L-1): 6.3±1.0, 26.5±1.5, 10.1±0.9, respectively.
The obtained results were based on the physicochemical properties of radionuclides, in particular the high affinity of 40K, 137Cs for crystalline structures that make up bottom sediments whereas 152Eu and 241Am preferably bind to the organic matter of bottom sediments forming potentially migrating speciation.

  • Time :

Abstract

Recent years have seen a sharp increase in the production of indices of vulnerability to climate change. Most of these indices of vulnerability to climate change have been primarily used for awareness-raising purposes rather than for guiding international policy. The Physical Vulnerability to Climate Change Index (PVCCI) proposed in this paper has been designed as an index of exogenous vulnerability, not influenced by the present policy of the countries concerned. As such it can be used as a criterion for guiding the international allocation of concessional resources (in particular those devoted to adaptation), as well as for the identification of the countries that are most vulnerable for structural or physical reasons. The index has been calculated for 191 countries. LDCs, SIDS, and African countries have a higher average score. However, there is a wide disparity in PVCCI scores within these three groups of countries, implying that a country-by-country allocation of resources should be used rather than an allocation by country group. The findings appear to be robust after comparison of various options.

Abstract

The integration of Management Systems (MS) within companies, namely, environmental management integrated with other management areas, such as, quality, corporate social responsability, energy and occupational health and safety, among others, is currently considered a strategic way towards sustainable development through lean and clean production, taking into account that resources are limited. Hence, sustainable development (SD) can be achieved through a better coordinated management of production processes versus associated resources, where it is of primordial importance the integration of environment with lean philosophy, that is, the designated lean green.
This presentation aims to highlight the main benefits of integrating the various management systems in organizations towards sustainable development. It addresses issues regarding the contributions resulting from the integration of various standardized MS, from both internal and external perspectives of organizations. Complementing the overall review of aspects to the development of integrated management systems, various works were conducted in order to identify and better understand the relevance of the success factors. An innovative model of integrated management systems towards sustainable development considering the Triple Bottom Line (economic, social and environmental) will be presented.
A proactive approach and commitment to resource savings and cleaner production supported by an integrated management system, brings relevant benefits for organizations in particular, and for humanity in general.

Abstract

The electricity consumed by the ACs will grow up to 3 fold by 2050 and it will be second largest electricity consumer after industrial sector. Over 95% of current cooling market is covered by conventional chillers because of advantages such as reliability and high performance. On the other hand, they have many disadvantages such as high maintenance cost, chemical refrigerants utilization, noise and vibration issues. Montreal Protocol and Europe Council Directive (3093/94) forced to stop the production of chemical based refrigerants and planned to eliminate completely by 2030.
In order to meet the cooling demand for human comfort and specially growing data center requirement, out-of-box solutions are required urgently. We proposed a disruptive cooling technology called water droplet indirect evaporative cooler (WD-IEC). It devoid the use of mechanical vapor compressors (MVC), chemical-based (chlorofluorocarbons) refrigerants, cooling towers, chilled and cooling water pipes, that eliminates more than 75% of conventional infrastructure of mechanical or thermally driven chillers. The proposed system utilizes only clean water for heat removal through evaporative potential of air. The initial results shows that the overall specific energy consumption can be reduced to 0.55±0.05 kWelectric per Refrigeration ton (Rton) from the conventional level of 0.85±0.05 kW/Rton. The other advantages includes; (i) zero global warming potential, (ii) three times less water consumption, (iii) maintenance cost is only 10% as compared to conventional chillers and (iv)simple and reliable operation. We also designed and fabricated 1 & 5 Rton commercial units those are under testing in real conditions and producing excellent results.

  • Time :

Abstract

EPA 3051A and Aqua Regia (AR) are widely adopted by global environmental agencies to assess soil quality in relation to potentially harmful elements (PHE). However, previous study has shown the formation of large amounts of short-range order materials (SRO) in the residues of these extractions. Residues obtained from the 3051A and AR were recovered from filter papers. To characterize the SRO in these residues, sequential extractions were performed with 0.2 mol L-1 ammonium oxalate (AO) and 0.5 mol L-1 NaOH. On average (n = 15), the 3051A and AR residues contained 37% and 60% of SRO, respectively. The largest amounts of SRO formed in the AR residue was in sample 5 (99% of SRO). The main component of the SRO was Al2O3-AO, Fe2O3-AO and SiO2-NaOH. The formation of SRO and PHE resorption levels were random and highly dependent on the mineralogy of the soil clay fraction. Soils rich in smectites, which are more common in temperate regions, formed larger amounts of SRO. The association of Pb with the SRO was more pronounced in the 3051A residue than in the AR residue. If SRO was not extracted after 3051A, in sample 7, for example, 595 mg kg-1 of Pb (10.2%) would have not been accounted. The maximum PHE resorptions in SRO were (%): Pb – 10; Cu – 470; Ba – 280; As – 21. The underestimation of PHE contents due to resorption mechanisms may lead an environmental agency to certify the use of an area contaminated with PHE.

  • Title:Optimal Supply Chain Design for First and Second Generation Bioethanol by Considering Energy Consumption, Market Incentives and Carbon Policies.
  • Time :

Abstract

Increasing demand for energy, environmental issue related to using fossil fuels, are driving bioethanol supply chain decision-makers to motivate biorefineries in using second-generation biomass feedstocks while reducing their carbon emissions. Implementing different carbon policies to control carbon emissions plays a vital role in planning bioethanol supply chains.
This study introduces a supply chain modeling approach that first locates the bioethanol plants in the State of North Dakota using Geographic Information Systems (GIS) analysis and then maximizes the profit of first and second generation bioethanol supply chains while considering the effects of different carbon policies (carbon tax, carbon cap, carbon cap-and-trade, and carbon offset) and monetary incentives on the supply chain decisions. The results show that the penalties for carbon emissions and energy consumption change the selection of birefineries in addressing in state and out of state demands in ways to maximize the profit of a bioethanol supply chain. The land rental cost is also highly influential in the selection of supply sources unless emissions or energy consumption are penalized. To switch to the second-generation bioethanol technology, a minimum incentive of $0.204/liter and $0.167/liter of bioethanol are needed to switch from corn-based to corn-stover-based and switchgrass-based bioethanol supply chains, respectively. Finally, carbon cap-and-trade is the best carbon policy since it causes the lowest profit loss (31.5%) and the highest reduction in emissions (up to 1.98%)

  • Time :

Abstract

In Bentael natural reserve, Byblos-Lebanon, a recently constructed road, adjacent to its Southside, is threatening the wildlife of the reserve. The first source of this pollution is a vehicle derived contamination of soil, air and plants. This study determines heavy metals contamination levels evaluated by a rare plant species ‘‘Urginea maritima”, which is used as a biomonitor of airborne pollution. Four heavy metals were chosen for their toxic effects on the floral species. Lead, cadmium, aluminium and chromium were studied in plant leaves. The analysis of heavy metals is completed by a measurement of the photosynthetic activity of the plant. Two years period study showed lead upgrade in leaves versus a chromium decrease of plant uptake from the first year of road inauguration. Aluminium and cadmium levels increase for the first months after road works beginning then decreased sharply. As for photosynthetic pigments, the study showed an adverse effect of heavy metals on ordinary photosynthetic activities of the plants. Chlorophyll revealed primarily a decline in activities the first year but then amplification, in contrast of pheophytin which concentrations displayed a sharp rise especially in the most closely site to the road. These results indicated that landscape activities near natural reserves initiate heavy metals pollution for plants with a high risk of accumulation.

  • 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:Reduction of Textile Microfibers’ Pollution: A New Filter Device For the Domestic Washing
  • Time :

Abstract

All textile articles detach microfibers when their washing process takes place. These microfibers (max. diameter 5 mm, length/diameter ratio 3:1) are considered as microplastics when the textile polymer has a non-natural origin. Some alternatives for the reduction of this pollution have been studied and proposed. Specifically, these include treatments for textile articles, devices for washing machines, and the microfibers’ removal efficiency in water treatment plants.
The treatment of textile articles in their manufacturing process, such as the application of coating materials, has the advantage that the generation of microfibers can be reduced at the source. However, it could be difficult to scale-up, as there are countless textile industries around the world, with many of them located in developing countries. Besides, there are different properties that the textile articles must fulfill (e.g., comfortability), which could be reduced when a coat is applied. Also, most of the synthetic fibers produced nowadays are made of polyester, a quite inert polymeric material hard to undergo consistent and durable treatments. Likewise, careful consideration must be put on the materials studied for these alternatives, as these could still generate another type of contamination.
On the other hand, water treatment plant facilities are usually very efficient in retaining microfibers. However, the global percentage of treated water is very low (20%) and the investment costs for constructing new facilities is very high. Besides, large volumes of washers’ effluents are routinely generated, which means that the number of microfibers that get through is still important. Moreover, as the microfibers are transferred to the sludge, these can still be release to the environment when compost is used as a by-product. Hence, these facilities are hitherto an unfeasible option in the short term.
Finally, the application of filter devices on washing machines is evaluated as a feasible option. These have the advantage of easiness to install and almost no extra energy supply requirements. In addition, there are easy to implement as the number of washing machine’s industries is relatively short. In this case, the final disposition of the microfibers is a subject that also needs to be approached.
In this work, a scalable and feasible device developed to catch these microfibers is presented. The device functions as a removable filter attached to the effluent of the washing machine. Moreover, the final disposal challenge is also considered. In this way, results of a post-treatment for the retention of microfibers are evaluated.

  • Title:Occupational Exposures to Rare Earth Elements (REEs): Current knowledge, On-Going Studies and Research Prospects
  • Time :

Abstract
Compared to the growing body of literature on REE-associated toxicity in a number of biota, relatively scarce reports are available on the effects of human occupational REE exposures. Early studies reported on the adverse effects of REE aerosol or dust, as case reports of respiratory damage in movie operators or lens grinders. More recent studies of occupational REE exposures were carried out on miners and on workers manufacturing cerium and lanthanum oxide, with reports of increased hair REE levels vs. controls, dysregulation of protein expression, and increased urinary REE levels vs. controls. A study of occupational exposures to REEs and other metals in e-waste processing was focused on the prevalence of anemia. The levels of REEs and other metals were found higher in anemic vs. non-anemic workers, suggesting that the higher REE and metal levels in anemic workers could play a role in the development of anemia.
Beyond the previously published studies, the currently widespread use of REEs in an extensive range of technologies raises environmental concern for occupational REE exposures including, among others, in the petrochemical industry and car repair due to the use of La in oil refining and of Ce for catalytic additives in diesel fuel production. We have an on-going study of REE levels in mechanic workshops, aimed at evaluating the effects of REE-containing diesel exhaust particulate matter among exposed workers. The current results point to different REE content on the workshop floor related to different exhaust abatement devices, as well as increased REE levels in urine of mechanics vs. controls. Whether, or not, REE excretion is accompanied by hair accumulation is a matter of on-going investigation.
Other subjects of investigation following occupational REE exposures, such as production of REE-containing super magnets for wind turbines and for hybrid engines, warrant ad hoc research efforts.

  • Time :

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.

  • Time :

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. Furthermore, this simulation approach shows a proper discharge curve at various C-rates and also highlights the concentration of li-ion, electrons, and heat flux with good stability in the Lithium-ion SSB.

  • Time :

Abstract

Graphene, the wonder material is just one of the many 2-D materials that have been discovered now. In constant efforts to improve the properties of the graphene, many new graphene-like materials have been developed such as graphane, fluorographene, white graphene, and various other forms of graphene (oxides, quantum dots, ribbons, coils, pillars and fibers). These graphene like or graphene based materials are the most studied and researched because of their excellent optical and electronic behavior as both these properties are of utmost importance while considering diagnostic applications. These have been used as biosensing platforms, anti-cancer agents, cell imaging and in photo-thermal applications, along with many other applications. For our applications, we explored graphene and graphene like nano-dimensioned materials as immobilization matrix for detection of anemia biomarkers, and cardiac biomarkers. These materials not only provide matrix but also facilitate fast reactions due their catalytic property which ultimately helps in signal amplification.

  • 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:The Impact of Resource Control on Electricity Systems
  • Time :

Abstract
Climate change requires tremendous efforts and the largest reconstruction of industry in the last 200 years. Fossil fuels must be
abandoned and replaced by other energy sources. This requires other types of resources, which are not necessarily more environmentally benign. As an example, the excessive use of biomass for energy conversion could cause more harm than fossil fuels ever did. For this purpose, it is an appealing idea to establish a system that controls the overall resource consumption by attaching a price tag to resources, including fossil fuels, land use, and minerals. The price is balanced by Ecopoints emitted to the worldwide population, purchasing as consumers the resources incorporated in goods. As the amount of available Ecopoints is limited, resource exploitation is, as well. An efficient use of resources requires therefore processes with a low resource consumption, the utilization of waste and recycling. From this perspective, electricity production from hard coal is about 250 time more expensive than hydro energy. It is revealing that wood requires a higher Ecopoint price than fuel oil for the same energy produced. Such a system could guide the industrial development to a more resource protective state by giving resource conserving processes a financial advantage, while consumers are allowed to gain financial advantage from their own consumption decisions.

  • Title:Analyzing The Levelized Cost of Hydrogen in Refueling Stations with On-site Hydrogen Production via Water Electrolysis in the Italian Scenario
  • Time :

Abstract
Hydrogen refueling infrastructures with on-site production from renewable sources are an interesting solution for assuring green hydrogen with zero CO2 emissions. The main problem of these stations development is the hydrogen cost that depends on both the plant size (hydrogen production capacity) and on the renewable source.
In this study, a techno-economic assessment of on-site hydrogen refueling stations (HRS), based on grid-connected PV plants integrated with electrolysis units, has been performed. Different plant configurations, in terms of hydrogen production capacity (50 kg/day, 100 kg/day, 200 kg/day) and the electricity mix (different sharing of electricity supply between the grid and the PV plant), have been analyzed in terms of electric energy demands and costs. The study has been performed by considering the Italian scenario in terms of economic streams (i.e. electricity prices) and solar irradiation conditions.
The levelized cost of hydrogen (LCOH), that is the more important indicator among the economic evaluation indexes, has been calculated for all configurations by estimating the investment costs, the operational and maintenance costs and the replacement costs.
Results highlighted that the investment costs increase proportionally as the electricity mix changes from Full Grid operation (100% Grid) to Low Grid supply (25% Grid) and as the hydrogen production capacity grows, because of the increasing in the sizes of the PV plant and the HRS units. The operational and maintenance costs are the main contributor to the LCOH due to the annual cost of the electricity purchased from the grid.
The calculated LCOH values range from 9.29 €/kg (200 kg/day, 50% Grid) to 12.48 €/kg (50
kg/day, 100% Grid).

  • 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.

  • Time :

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.

  • 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.

  • Time :

Abstract
In recent years, with the continuous development of equipment manufacturing industry, the
high performance titanium alloy and superalloy seamless rings have been widely used. These
seamless rings mainly include aeroengine casing rings, carrier rocket capsule rings, gas
turbine rings, oil/gas pipeline rings and so on.The metal rings hot rolling technology has
become an irreplaceable manufacturing technology with low consumption, high efficiency
and performance.
Owing to the special features of the titanium alloy and superalloy——bad thermal processes
plasticity and strong processes sensitivity, cracks occur easily with the metal temperature drop
in hot rolling processes.At the same time, the metal surface oxidation in the heating processes
will also affect the surface quality and performance of rolled parts. Therefore, usingheat
preservation and protective coatings is the most effective and simple solution.
In view of the above problems, Beijing Tianlichuang Glass Technology Development Co., Ltd.
has successfully developed the water-based heat preservation coating for titanium alloy and
superalloy hot rolling at different rolling processeses.The coatingsare coated on the metal
surface at room temperature, and then the billet can be heated in the furnace after it is dried.
During the heating processes, the coatings can prevent the metal oxidation at high
temperature, and the coatings canplay a role of heat preservation during transfer and rolling
processes, while the coatings have no lubrication effect when rolled.The representative
coating models are TZH-1, GZH-3 and GZH-5, and the specific applicable processesare shown
in table 1.At the same time, we can also research and production new heat preservation
coatings according to different needsof clients.

GZH-3 1000~1100℃ 0~10hours
GZH-5 1000~1200℃ 0~10hours
Non-crystalline glass powders and minerals are main solid base materials of heat preservation
coatings. They are blended with additives, adhesives and water, then applied to metal surfaces
by brushing or spraying before heating.In the design of coating formulas, the specific hot ring
rolling processes (heating temperature, holding time, furnace atmosphere, hot rolling
condition) of titanium alloy and superalloy should be considered. The coatings should have
outstanding compatibility with the metals, and have appropriate high temperature viscosity
and expansion coefficient, to achieve perfect match with different hot rolling processes.The heat preservation coatings can solve the problem of hot insulation and protection of
titanium alloy and superalloy inhot ring rolling processes, and can reduce the surface crack of
metals after hot rolling, making the metals easier to obtain uniform and fine
microstructures.The coatingsare simple to use, non-toxic and environmental friendly.

  • 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.

Abstract
For the optimization of envelope characteristics also the shape of the building, an optimization– simulation technique is applied in this paper. To obtain the best values of all related variables for
the minimization of energy consumption in residential buildings, an improved Manta-Ray Foraging Optimizer is considered as the optimization algorithm. Also, for whole-building energy simulation, RIUSKA is used. The optimization parameters are the area and type of the windows, foundation, wall and roof insulations, level of infiltration, orientation, and thermal mass. Various forms of the building including rectangle, trapezoid, T-shape, H-shape, cross, L-shape, and U-shape are studied. The model optimization process takes fewer computation time and expense. Moreover, the utilized technique implements fully proper in comparison to the particle swarm, approximating very close to
the optimum in less than 50% of the simulations The lowest life cycle cost is achieved by the buildings with trapezoid and rectangle form for five various climatic conditions. Also, the minimum variation from the optimum to the worst is observed by trapezoid and rectangle. The change in the values of
the life cycle cost is lower than 4.5%.

  • 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.

  • Time :

Abstract
The high levels of iron and manganese found in ground water and utilized by living habitats has made it mandatory to seek a local low cost effective technique to decrease their concentrations. In this study, vermiculite clay and cation exchange resin were used as adsorbent and filter media to examine their ability in the removal and retention of those soluble metal. Different initial concentrations of 2, 5, 10, 30, and 50 ppm were examined using column testing. Vermiculite clay could remove iron up to 95% for the 5 ppm initial concentration and completely remove iron form the initial 2 ppm concentration at 70 min. Cation exchange resin worked better at lower concentrations yet couldn’t attain the allowable drinking water levels. For manganese, cation exchange resin performed better, where the highest removal rates attained for the 5 and 2 ppm were 99% and 100% successively within the first 10–20 min.

  • Title:Fungal pathogens Infecting Moss Green Roofs in Finland.
  • Time :

Abstract

Green roofs play an important role for cities in mediating some problems caused by urbanization. Mosses are ecologically important plants and capable of tolerating harsh conditions, and thus their use for greening building surfaces has become more common. There is only a little information concerning moss-associated microbes, especially those found in green roof environments. Moss-associated microbes might have significant role on the welfare of green roofs as they might induce both beneficial as well as adverse effects on mosses. In this study, the occurrence of fungal populations was studied on green roofs in Finland. A total of 94 samples were collected from nine different green roofs, and 64 fungal isolates and one oomycete were obtained from the brown, necrotic parts of the collected green roof mosses. The most general isolated fungal genus was Trichoderma, comprising 25 different fungal isolates. The second most common genus was Fusarium, with 15 fungal isolates. The third most common genus was Mucor, with nine fungal isolates. Most of the Trichoderma isolates were described as T. harzianum, whereas most of the Fusarium isolates were described as F. acuminatium. In addition, the genera Phoma and Mortierella were frequently present. Fifty- two of 65 isolates caused symptoms in the model plant Physcomitrella patens. The most harmful Trichoderma isolates were described as T. atroviride, T. viride, T. koningiopsis and T. hamatum, all of which caused severe damage to the protonema, stem and leaves. The most harmful Fusarium isolates were F. acuminatium, F. avenaceum and F. tricinctum. The genera Mucor and Mortierella were isolated but they did not cause detectable symptoms in P. patens. These results indicate that many fungal isolates belonging to different genera are able to colonize mosses on green roofs and some of them cause severe damage to the mosses.

  • 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:An Equitative Autonomous Distributed Demand Side Management System for Peak Shaving and the Air Conditioning Trap Problem
  • Time :

Abstract
Climate change is currently affecting weather patterns, producing more severe storms, harsher weather, and heat waves in places never seen before. In particular, it brings the so called Air Conditioning Trap Problem: Greenhouse gases produce more heat in the atmosphere and heat waves (warmer weather in places never seen before), that gets people around the world to use their air conditioning devices more frequently. These excessive electricity consumption in turn produces more greenhouse gas, closing a vicious circle. This tendency is aggravated by the widespread use of light building materials, such as plaster of glass, that are very poor thermal insulators and require more electricity to maintain a given temperature indoors.
In this work we present an autonomous distributed artificial intelligence based on artificial immune networks, that controls the starts and stops of power-shiftable thermal devices such as Air Conditioning systems. The system is able to work on a limited number of controlled Air Conditioning devices, with only one-way communication (broadcast), respecting a maximum electricity consumption and maintaining the human thermal comfort of the occupants. This in turn allows us not only to diminish total energy consumption, but enables a more efficient use of renewable energy sources (by limiting the consumption to the energy that the source can provide, among other possibilities).
The system is an improvement over a previous work by the same authors, where the different nodes are able to distribute the energy in an equitable way without transversal communication.

  • Time :

Abstract
Waste disposal is becoming more and more challenging. Indeed, global population is still increasing and countries that do not have enough space to create big landfills need to find other solutions to deal with this problem. The incineration of municipal solid waste (MSW), if well controlled, is a possible solution. According to Cheng and Hu (2010) * incineration can reduce the volume occupied by MSW down to 90% while producing thermal and/or electrical energy. Also, the clinker of incineration can be used in road building and the construction industry. But air pollution control remains a major problem in the implementation of incineration for solid waste disposal. Despite the long history of work in this area, the proposed control schemes of these waste-to-energy plants are quite basic. This paper presents a way to optimize such a plant by using Advanced Control techniques. The aim of this operation is to control the steam flow rate, and, therefore the energy production, while ensuring a complete combustion, which is synonym of minimal pollution emission.

  • Title:Green Deal – Tox Free environment and the New Data Base for Substances of High Concern: How Useful is SCIP Database for Waste Management Sector?
  • Time :

Abstract
The European Commission had set two important goals with the 7. Environmental Action Program, the new Green Deal and Chemicals`strategy from 2020. The first is to minimize exposure to chemicals in products and promote non-toxic material cycles to ensure the health protection of EU citizens from environmental exposures and risks. The second goal envisions the transformation of the EU into a resource-efficient, green, and competitive low-carbon economy. This will be achieved through higher recycling rates and non-toxic material cycles. The Commission is working to minimize hazardous substances in products. However, if substances of concern are to be removed, it must be made clear which ones are contained at all. To ensure this knowledge, a duty to inform manufacturers of products about hazardous substances contained therein (SVHC – substance of very high concern) was introduced in the amendment of the Waste Framework Directive (WFD) in 2018, which must now be implemented (starting point: January 5, 2021). In practice, however, the implementation of this information obligation proves to be difficult because, especially in the case of waste, the products contained therein are not known or not fully known and these usually also contain no reference to “pollutants” contained. Due to the large amount of data and the complexity of the database, this proves to be problematic for both producers and the recycling industry. But what data are needed in the first place to make a decision about the recyclability of contaminated waste, and what data can be expected from SCIP?

  • Title:Utilization of δ-Manganese Dioxide for the Removal of Indigo Carmine from Aqueous Solutions
  • Time :

Abstract
In recent years, water contamination has become a global concern that hinders environmental sustainability, the integrity of the aquatic ecosystems and the prosperity of human societies. Water contamination can derive from numerous sources, including industrial discharges and effluents that present high content of organic chemicals. A certain category of organic chemicals that endangers environmental sustainability is synthetic organic dyes, currently used by numerous industries, which can enter the aquatic environment due to their incomplete attachment on their substrates. Indigo Carmine, an organic water-soluble salt, is utilized by food, clothing and pharmaceutical industries, and has been linked with carcinogenesis, neurotoxicity and other severe health effects at high concentrations. Consequently, purification of water contaminated with Indigo Carmine is vital, and many methods have been applied towards that goal including oxidation, adsorption, photocatalysis and bacterial treatment. In our previous work, we have studied the removal of Indigo Carmine from aqueous solutions via adsorption onto chitosan based functional materials. However, oxidation of Indigo Carmine is also a well-established method that possesses several technical and economic advantages (i.e. reduced demands for chemical auxiliaries and reaction times). Thus, research has been focused on the evaluation of the efficacy of various oxidizing agents, with manganese oxides presenting promising results. Manganese oxides are a class of naturally occurring and ubiquitous materials that due to manganese’s ability to exist in different oxidation states can simultaneously oxidize and adsorb organic contaminants from the aquatic environment. Especially, manganese dioxide has been proven to oxidize organic chemicals by a series of one-electron transfers, which result in radicals’ formation that can either form polymeric compounds or undergo further oxidation. In particular, δ-manganese dioxide has a reduction potential of 1.23 V and is commonly found in soils, thus it is an appealing material for water decontamination. The present study aims to investigate the purification of Indigo Carmine contaminated waters by means of δ-manganese dioxide and evaluate the effect of various operating conditions (i.e. pH, concentration of Indigo Carmine and δ-manganese dioxide, and temperature) in order to assess the possibility of maintaining environmental sustainability through an eco-friendly and naturally occurring material.

  • 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.

  • 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.

  • 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.
