In 2010, the global transport sector consumed about 2,200 million tons of oil equivalent. About 96% of this amount came from oil. It shows that more than 60% of the oil consumed globally goes to the transportation sector. Road transport accounts for the bulk of the transportation energy consumption. The light-duty vehicles (LDVs), including light trucks, light commercial vehicles, and minibuses...
Engine oil consumption is an important source of hydrocarbon and particulate emissions in modem automobile engines. Great efforts have been made by automotive manufacturers to minimize the impact of oil consumption on engine emissions. Research engineers in the last decade have been trying to study the sources and driving mechanism of oil consumption. In contrast to oil consumption mechanisms i...
Consumption of different types of oil may have different effects on cardiovascular risk. The exact role of maize oil, cod liver oil, soya oil and extra virgin olive oil on endothelial function, oxidative stress and inflammation is unknown. We evaluated the effect of acute consumption of these types of oil on endothelial function, oxidative stress and inflammation in healthy adults. Thirty-seven...
Commodities are back in the news. The early twenty-first century seems to have witnessed an upsurge in the old conflict over valuable resources, leading to a global scramble for commodities, and bringing in its wake renewed international tension, war, dispossession, and environmental degradation. The Cold War clash of ideologies, it has been argued, has been replaced by global competition betwe...
Oil and energy markets have experienced dramatic changes over the past three decades. Due to these changes, it may be difficult to model and forecast the oil consumption with traditional methods such as regression. Artificial Neural Networks (ANNs) are the strong rival of regression and time series in forecasting. ANNs provide good accuracy along with more reliable and precise forecasting for p...
This study proposed a novel way for global greenhouse gas reduction through reusing China's waste oil to produce biofuels. Life cycle greenhouse gas mitigation potential of aviation bio-kerosene and biodiesel derived from China's waste oil in 2010 was equivalent to approximately 28.8% and 14.7% of mitigation achievements on fossil-based CO2 emissions by Annex B countries of the Kyoto Protocol i...
● Global reserves of coal, oil and natural gas are diminishing; global energy requirements however are dramatically increasing. Renewable energy sources lower the threat to the earth’s climate but are not able to meet the energy consumption in major urban areas. The opinion of many experts is that the future will be dominated by hydrogen. However, this gas is essentially totally manufactured fr...
Biotech crops have now been grown commercially on a substantial global scale since 1996. This paper examines the production effects of the technology and impacts on cereal and oilseed markets through the use of agricultural commodity models. It analyses the impacts on global production, consumption, trade and prices in the soybean, canola and corn sectors. The analysis suggests that world price...
life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...
