Agriculture is one among the sources of greenhouse gas emission in World. Agriculture, being a prominent source economic sectors developing countries its impact on environmental climate changes both directly and indirectly through gases. To achieve reduced GHGs emissions agriculture sector, there need to adopt smart activities improved food nutritional security ensure climate-smart sustainable ...
Spiraling continued increase in Emission of Green House Gases [GHG] play a significant role impacting the environment and also human beings at large. Although recent studies have concentrated to an extent on developing schemes for reduction Carbon dioxide emission identified methodologies implementing same, sufficient amount not been done other greenhouse gases which adverse global impact as di...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
Traditional oil consumed transportation including vehicles and vessel produces green house gases, which is not environmentally-friendly. As a new type of energy-consumed unit, the fuel cell popular due to its less emission level, high efficiency low noise. This paper introduces principle characteristics cell, with further introduction application status system in vehicle maritime industry. Furt...
In the recent years, the amounts of green house gases have dramatically increased. This situation led to changing in climate conditions. One of the effective ways to reduce these amounts in atmosphere is CO2 capturing from huge spreading sources and injection it into geological formations. Peridotite is a type of rock that reacts with CO2 at higher rate when compared to the other rocks. Since t...
Carbon dioxide (CO2) is one of the main gases produced by human activity and is responsible for the green house effect. Numerous routes for CO2 capture and reduction are currently under investigation. Another approach to mitigate the CO2 content in the atmosphere is to convert it into useful species such as hydrocarbon molecules that can be used for fuel. In this view, copper is one of the most...
The foremost issues of 21 century are challenging demand of electrical energy and to control the emission of Green House Gases (GHG) emissions. Renewable energy resources based sustainable microgrid emerges as one of the best feasible solution for future energy demand while considering zero carbon emission, fossil fuel independency, and enhanced reliability. In this paper, optimization and impl...
This paper addresses the optimal design and location facility of biodiesel supply chains (BSC) under economic and environmental criteria. The economical aspect scale is assessed by the total annualized cost. The environmental objective is evaluated by the total GHG (Green House Gases) emissions for a whole life cycle. A mathematical model that can be used to design the supply chain (SC) and man...
Energy consumption by computer systems has emerged as an important concern, both at the level of individual devices (limited battery capacity in mobile systems) and at the societal level (the production of Green House Gases). In multicore architectures, applications may be executed on a variable number of cores and these cores may operate at different frequencies. The performance and energy cos...
