In developing countries like India, urban solid waste (SW) generation is increasing enormously and most of the SWs are disposed off by land filling in low-lying areas, resulting into generation of large quantities of biogas. Methane, the major constituent gas is known to cause global warming due to green house gas (GHG) effect. There is a need to study the ever-increasing contribution of SW to ...

Construction and mining industries are using more than 20% of all non-road engines and listed as the third largest contributor to greenhouse gases (GHGs) emission globally. GHGs emitted from engines in construction and mining sites have not been fully investigated yet. Normally, government agencies and construction contractors estimate emitted pollution approximately based on consumed fuel for ...

Ammonia emissions from swine feeding operations depend on the housing type; animal size, age, and type; manure management, storage, and treatment; climatic variables; and manure utilization or land application techniques. Techniques or methods for estimating or quantifying NH3 flux from a source to the atmosphere include nitrogen mass balance, micrometeorology, flux chambers, models, and emissi...

The INTEGRAL observatory has been performing a deep survey of the Galac-tic central radian since 2003, with the goal of both extracting a catalog of sources and gaining insight into the Galactic diffuse emission. This paper concentrates on the estimation of the total point sources emission contribution. It is now clear that unresolved point sources contribute to the observed diffuse emission; t...

issues related to environment are one of the most important issues the communities are facing with in the recent decades. on the other hand, the resource scarcity and the necessity of development for iran and other similar countries makes the issue of efficiency as a solution of the environmental crisis important. in this study, the effects of the variables energy intensity (as one of the most ...

We use absolutely calibrated data from the ARCADE 2 flight in July 2006 to model Galactic emission at frequencies 3, 8, and 10 GHz. The spatial structure in the data is consistent with a superposition of free-free and synchrotron emission. Emission with spatial morphology traced by the Haslam 408 MHz survey has spectral index βsynch = −2.5± 0.1, with free-free emission contributing 0.10 ± 0.01 ...
