Soil properties and soil-atmosphere fluxes of CO2, CH4 and N2O from four coastal wetlands were studied throughout the year, namely, native Kandelia obovata mangrove forest vs. exotic Sonneratia apetala mangrove forest, and native Cyperus malaccensis salt marsh vs. exotic Spartina alterniflora salt marsh. Soils of the four wetlands were all net sources of greenhouse gases while Sonneratia forest...

Concerns about atmospheric emissions of greenhouse gases and operation costs are converging to increase incentives for both the electric utility and magnesium industries to rapidly locate and repair equipment leaks (Irwin, 1997). The primary culprit is sulfur hexafluoride (SF6), an invisible, non-hazardous, inert gas with near-perfect dielectric properties that is used as an insulating gas in h...

A transition from the global system of coal-based electricity generation to low-greenhouse-gas-emission energy technologies is required to mitigate climate change in the long term. The use of current infrastructure to build this new low-emission system necessitates additional emissions of greenhouse gases, and the coal-based infrastructure will continue to emit substantial amounts of greenhouse...

Besides its great potential in controlling water pollution from different sources, waste water treatment system generates significant amount of greenhouse gases. Hence, reducing the emission of greenhouse gases from the wastewater treatment plants is the major concern. The correct understanding and estimation of the greenhouse gases emitted from different points of the plan is essential to tack...

the goal of this study was to analysis the greenhouse gas (ghg) emissions of pasta production. data for this study was collected from durum wheat farms of three provinces of iran. data of soil properties, transportation and pasta factory stages were collected and analyzed, using simapro software, ecoinvent data base and global warming potential (gwp) 100 years method. epic model was used to cal...

One of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. The cars intensify greenhouse gas emission in civic centers. One approach to reduce the emission is replacing the cars by Plug-In Electric Vehicles (PEVs). In spite of reducing the emission, PEVs have some adverse effect on electric distribution networks. Technical challenges such as load and...

[1] Current good practice guidelines for national greenhouse gas inventories requires that seasonal variation in emission factors from savanna fires be considered when compiling national accounts. African studies concluded that the emission factor for methane decreases during the dry season principally due to curing of the fuels. However, available data from Australian tropical savannas shows n...

increasing the concentrations and emissions of greenhouse gases makes the weather warmer and affects land uses. carbon dioxide emission is recognized as one of the most important factors in global warming. the objectives of this research were to investigate the amount of co2 emission from soil to atmosphere during the wheat growth under two different tillage and irrigation methods. in this stud...
