Methanogenesis is a microbial process in which organic matter is assimilated and metabolized with the ultimate production of biogas that contains methane and carbon dioxide in the approximate ratio of 2:1. It represents a major electron sink in the metabolism of termites. An understanding of the dominant methanogens inside termite gut and their efficiency in the production of methane can find a...

This paper presents an interactive simulation of the effects of emissions and absorptions of anthropogenic carbon dioxide (CO2) in the atmosphere. The interactive simulation based on the “bathtub” metaphor, was built using the Dynamic Integrated Climate Economy model (DICE)-1992. The interactive tool allows participants to make decisions on the anthropogenic CO2 emissions, observe the consequen...

Methane is the second most important greenhouse gas (GHG) after carbon dioxide. Amount of methane emission from energy sector is increasing day by day with various activities. In present work, various sources of methane emission from upstream, middle stream and downstream of oil & gas sectors are identified and categorised as per IPCC-2006 guidelines. Data were collected from various oil & gas ...

Carbon dioxide, methane and nitrous oxide are the major Greenhouse Gases (GHG’s), which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. Therefore, there is immense concern for its abatement or utilization from landfi...

urbanization, population growth and moving from traditional manufacturing industry to accelerate the process of economic development and parallel, significant environmental impacts are left. the purpose of this study is to investigate the effect of different variables such as trade openness, comparative advantage, production levels and other important variables affecting the emission of carbon ...

Air quality assessment of the emission from power plant and traffic at Al-Taneem area located at the northern part of the Holy City of Makkah, Saudi Arabia, is investigated. Concentration levels of different pollutants including nitrogen dioxide (NO(2)), sulfur dioxide (SO(2)), carbon monoxide (CO), ozone (O(3)), methane (CH(4)) and total hydrocarbons (THC) as well as some meteorological parame...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...
