boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
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...
background and purpose: due to the lack of accurate statistics on the amount of waste generated in the energy production sector in zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in zahedan. materials and methods: this research is a cross-sectional descriptive study. it examined the ...
The number of farm-based biogas plants in Austria increased rapidly in the recent past, a continuing interest in this technology is expected. A survey was carried out in 2002 to provide information for farmers and the decision makers involved. In most plants slurry and manure is co-digestion with energy crops and/or organic waste. Wet fermentation in mesophilic digesters with post-digesters com...
A waste-to-energy firm that recycles organic waste with energy recovery performs two environmentally beneficial functions: it diverts waste from landfill, and it produces renewable energy. At the same time, the waste-to-energy firm serves and collects revenue from two types of customers: waste generators who pay for waste disposal service, and electricity consumers who buy energy. Given the pro...
Efficient waste paper recycling has a significant role in the sustainable environment. Recyclable waste paper as a fundamental ingredient of municipal solid wastes (MSWs) is indeed an ‘‘urban ore’’. Waste papers are considered as the solid recovered fuel which is recovered from MSW. Recyclable waste papers are segregated into various grades to produce high-quality products. Moreover, sorted pap...

This paper presents the results of a research into the feasibility of recovering waste heat and determining design parameters of a recovery boiler for a set of medium-speed diesel generators with a capacity of 7 MW (the nominal capacity of all units is 42 MW, which would be a study on a unit). And is used to generate electricity. The main purpose of this study is to design a thermal waste recov...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
