processing of round potatoes (solanum tuberosum (l.) into chips in tanzania and particularlydar es salaam city is a growing business that attract low wages employees and unemployed occupants. proliferationof chips vendors with low knowledge, poor attitude and practice towards environment have resulted into poormanagement of potato peels waste which are haphazardly disposed of thus causing unhea...
The response of climate to perturbations in GHGs is location dependent. Six experiments: control (CTRL); double CH4; double CO2; double N2O; halved CFC11 and halved CFC12 were carried out to reveal the local area response to different GHGs levels in the atmosphere over West Africa. Double CH4, CO2 and N2O generally induce wetness but they also induce localized dryness at the hilly and mountaino...

The tropical Indian Ocean has experienced a faster warming rate in the west than in the east over the twentieth century. The warming pattern resembles a positive IndianOcean dipole (IOD) that is well captured by climate models from phase 5 of the CoupledModel Intercomparison Project (CMIP5), forced with the two main anthropogenic forcings, long-lived greenhouse gases (GHGs), and aerosols. Howev...
An increase in fossil fuel consumption has significantly increased the concentration of greenhouse gases (GHGs). Waste energy recovery can reduce GHGs by reducing fossil fuel consumption. In the FCC unit in refineries, the catalyst is continuously regenerated by burning off the deposited coke with air and a large flux of waste gas with high temperature is generated which is vented into the atmo...
The main greenhouse gases (GHGs) producer is represented by the fossil burning systems. The paper presents the effect on the GHGs emission combined with the economic effects of a new pumping system method of automatic mixing of hot and cold water circulated with variable speed driving pumps and adjustable vanes. Considering the potential economic and environmental effects combined with the soci...
Carbon dioxide currently accounts for about 49 percent of the radiative forcing of the atmosphere that is attributable to greenhouse gases (3.0 watts per square meter [W m-2]; Houghton et al. 2001). Tropospheric ozone and black carbon are responsible for another 18 percent, and the well-mixed greenhouse gases (GHGs)—principally methane, nitrous oxide, and various halocarbons—are responsible for...

the aim of this paper is to assess the adaptation of iran’s energy policies to the kyoto protocol. in the past two decades, iran has experienced a considerable increase in greenhouse gas (ghg) emissions; in 2013 it was the world’s ninth largest emitter. although adapting to this protocol in iran’s energy and climate policies seems vital and urgent, its recent status is not promising. this paper...
