in this research, the energy flow and production energy indices of canola cultivation in trakya province of turkey, golestan and mazandaran provinces of iran were compared. diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. the results indicated that despite the higher energy use of machinery in trakya province of t...
Trade liberalization has impacts on the quality of the environment, i.e. on the emission of pollutant gases according to its size, composition and technology. On the other hand, trade liberalization is followed by international capital mobility intensification. Meanwhile according to the Pollution Haven hypothesis, transfer of pollutant industries starts from countries with tough environmental ...
Refineries produce about four percent of the global carbon dioxide emissions, close to one billion tons per year. Globally, the refining sector is the third largest producer of carbon dioxide after the electricity generation and cement industry.This greenhouse gases is a major cause of global warming and climate change and is a serious threat to human health and the environment. One way to redu...
optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...
When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a combination of nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon dioxide, which contributes about 5% of the total volume, the diesel engine exhaust consists of elements which are part of...
Due to the potentiality of the accumulation of atmospheric carbon dioxide and its permanent nature, the actual amount of carbon dioxide in the atmosphere, the accumulation of effective per capita carbon dioxide and the accumulation of effective per capita of this pollutant in the steady state has been estimated estimated through Kalman filter approach in a Ramsey equilibrium model over the peri...
Given the importance of the issue and the undeniable role of the environment in the community's life, in this research, it is attempted to test the hypothesis of the relationship between the government size and composition of government expenditure (Current and developmental) on carbon dioxide emissions in Iran during 1971-2016 based on autoregressive distributed lag approach. To better explain...
Regional carbon dioxide emissions study is necessary for China to realize the emissions mitigation. An environmental input–output structural decomposition analysis (IO-SDA) has been conducted in order to uncover the driving forces for the increment in energy-related carbon dioxide emissions in Xinjiang from both production and final demands perspectives from 1997 to 2007. According to our resea...
On June 25, 2013, President Obama announced his plan to introduce carbon dioxide emission standards for electricity generation. This paper proposes an efficiency analysis approach that addresses which emission rates (and standards) would be feasible if the existing generating units adopt best practices. A new efficiency measure is introduced and further decomposed to identify different sources’...
The mass spectrometric analysis of the impact of sulfur dioxide and dust emission on carbon and oxygen stable isotopic compositions of glucose hydrolysed from α-cellulose samples extracted from Scots pine growing in the vicinity of "Huta Katowice" steelworks was the main aim of this study. The annual rings covered the time span from 1975 to 2012 AD. The relationships between climatic conditions...
