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


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.

My previous research work has focused to describe fungal pathogens of green roof mosses and the signaling pathway induced by fungal cell component in Physcomitrella patens. My present research work specialize to study microbial products used to alleviate the problems in sewage drain and grease wells.

  • Time :

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:Regional Comparison on Energy Efficiency Drivers
  • Time :

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 :

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

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:Research and Properties of Heat Preservation Coatings for Hot Ring Rolling of Titanium Alloy and Superalloy
  • Time :

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.

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


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:Optimized Conversion of Waste Cooking Oil into Ecofriendly Bio-based Polymeric Surfactant- A Solution for Enhanced Oil Recovery and Green Fuel Compatibility
  • Time :

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:Subcritical Nuclear Reactor Driven by ion Beams
  • Time :

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.

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

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

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

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.

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.
