in order to examine the hypothesis of this research, an accidental sample of 122 students have been appointed from among the community of female students who were studying at the last year of primary school in isfahan . the sample was divided into four groups, cognitive group, behavioral group, cognitive- behavioral group and control group. the impacts of independent variables have been assesse...
The information technology is powered by electricity. Although its impact on Green House Gasses (GHG) is still rather limited, the next decade will show an explosion of its impact because technological innovations in data communication, information retrieval and datacenter operation will not compensate the increased need for energy of information technology. This paper approaches the problem no...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
the drought continuity and also restricting watery sources caused agriculture section forgetold flooding methods for optimum water exploitation and proceeding new irrigation systems.new generation of irrigation systems called intelligent systems is a new solution leading toexploiting water increase to higher than 80%. in order to measure sensors and to controlprocessors in designing and dismoun...
Global warming has been largely driven by increasing atmospheric GHG (Green House Gasses), particularly carbon dioxide caused by fossil fuels burning. The current trend can not be stopped except by reducing fossil fuel consumption or storing organic carbon in soil or earthchr('39')s biological systems such as forests, rangelands and agricultural systems. This study was conducted to determine th...
Now-a-days Smart Grid is becoming a key element of energy strategies. Several definitions are coming in different literature but the overall meaning of these different definitions are same. Smart Grid is an intelligent monitoring, control and self healing of an electrical system with the help of information (data) communication in between the end user or generating station and control room. Thi...
Abstract The manufacturing of cement liberates the green-house gasses into atmosphere. To overcome this problem so many alternative materials has been invented by researchers to minimize addition cement. incorporation these as cementitious material in concrete enhances attributes concrete. In scenario metakaolin gained momentum a substitution Most studied performance incorporating normal curing...
Cattle rearing generate more global warming green house gases than driving cars. These green house gases leads to changes in the climate. This climate change affects the livestock, man and natural environment continuously. For this reason it is important for livestock farmers to find the ways which minimize these gases emission. In this article the causes of climate change and effects, measures...
Mass production of paper is one the significant factors that are contributing to increase in carbon outrush global ecological system. The trade releases large volumes air, water, and soil pollutants, which pony up green house gasses. rotted methane gas, many times more hazardous than dioxide. Paperless business a vital environmental practice better for upliftment current degrading environment. ...
Does motor efficiency relate to “going green”? While the term going green originally applied to the release of greenhouse gasses, it has been broadened to include waste and inefficiency associated with factory operations in general and motors specifically. The green movement as it relates to motors is the result of industry becoming environmentally conscious with a wary eye on reducing its carb...
