transportation is an important part of modern community life as well as one of the largest sources of greenhouse gas emissions in urban communities, the population growth of which can increase transportation capacity. monorail systems are relatively new rail transportation systems which are currently being designed and constructed in different countries. we have applied the intergovernmental pa...

air conditioning refrigerant r134a has value of global warming potential (gwp) 1300, which is much higher than mac directive (gwp below 150) passed in july 2006. this prompted a search for alternative refrigerant with gwp value less than 150. r1234yf is a new refrigerant which has lower gwp value of 4. effect of blower speed has been compared and flammability issue of r1234yf has been addressed...

agricultural activities have always been partly responsible for the emission of greenhouse gases and other environmental contaminants in the atmosphere. thus, studying on the environmental effects of agricultural activities and proposing appropriate strategies to mitigate these adverse effects can be paramount importance. in this study, in order to determine the environmental impacts of peanut ...

lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. in this paper, the environmental problems of lead and zinc production in calcimin plant are expressed and life cycle assessment of this plant is assessed. the data regarding the amount of induced global warming and pollution, acidification, and depletion...

Background: Due to the greenhouse gases emission caused by human activities there is wide agreement about global warming. Methane is one of the most dangerous greenhouse gases in the global warming process which is produced through human activities and natural processes. In addition, the use of fertilizers and chemical pesticides would produce nitrogen monoxide in the atmosphere. This gas is an...

global warming is claimed to be the cause of climate change, which is often held responsible for water shortage.  let geopedology represents the complex process of soil formation, out of which much can be learnt about paleoecology; soil formation being a dynamic interaction between the atmosphere, biosphere, lithosphere, and the hydrosphere. in a multidisciplinary sustainability-oriented study ...

an abrupt global warming event has been recorded in many parts of the world in sediments of latest maastrichtian age between 65.45-65.10 ma. this warm event was documented here at a section near ziyarat-kola in central alborz based on analysis of planktonic foraminifera. an unusual abundance of normally large-size species such as globotruncana arca, globigerinelloides subcarinatus, pseudoguembe...

this study aimed to evaluate the environmental consequences of kiwifruit production in guilan province of iran by the life cycle assessment (lca) methodology during growing season of 2011-2012. data were obtained from 84 kiwifruit producers using a face to face questionnaire method. for this purpose, a functional unit equal to one ton kiwifruit was assumed based on iso 14040 method. impacts of ...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Printer-friendly Version Interactive Discussion EGU Abstract Subsurface temperatures in Bangkok, where population and density increase rapidly, were analyzed to evaluate the effects of surface warming due to urbanization. The magnitude of surface warming evaluated from subsurface temperature in Bangkok was 1.7 • C w...
