background: one of europe’s most well-developed industrial regions is found in the republic of bulgaria. the industrialization of the region has a big impact on air pollution. thermal power plant “maritza east” (the largest of its kind in southeastern europe), the army training range, machine manufacturers, household heating and high volume of automobile traffic are all major sources of polluti...
fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...
C is in the midst of the largest and fastest period of economic growth in global history. While this growth at 9 10% GDP per year has lifted hundreds of millions of people from poverty, the all out prioritization of economic prosperity has created serious air and water pollution that are affecting the health of the local population, and also have increasing global climate impacts. A World Healt...
Iron and steel is an energy intensive industry and its contribution to the pollution of environment is considerable. Direct reduction iron (DRI) is a major element of an iron and steel production plant. Its share in natural gas and electricity consumption of total plant is estimated to be 70% and 15% respectively. Reduction gases are produced in natural gas reforming unit and its elements are C...

So the World Health Organization has reported more than 1.3 million premature deaths due to urban air pollution in 2010. Continuous monitoring of air quality to determine pollutants and identify their emissions sources are considered a...
Thermal energy is one of the most important issues in most industries, because conversion of energy from fossil fuels to thermal energy occurs in almost all conventional industries. Therefore, considering the lack of fossil resources and the increasing pollution of human environments, attention to the proper use of thermal energy should be considered by researchers. In recent years, attention h...
