greenhouse gases emissions from burning fossil fuels and the effect of these gases on climate change is one of the most important ecological and political issues. in this study the energy consumption and greenhouse gas emissions from tillage and soybean planting were assessed in gorgan. this study is done on 13 soybean farms in 2012. information related to tillage and planting operations were p...
Energy footprint assessment in Abadan oil refinery and solutions to achieve green productivity goals
The aim of this article is to analyze SEC critically in relation to refinery industrial energy efficiency. In this study, the effect of various parameters such as input energy carriers, output energy, API value, and input refining oil was investigated. Specific energy consumption of unit and standard criterion was obtained 2.30 and 3.06 Gj/ton, respectively, that the total specific energy consu...
Background: Hospitals as major energy consumers can manage their energy consumption by intelligent interventions. Therefore, this study aimed to determine the amount of energy consumption of Water, Electricity, and Gas, and their association with functional indicators in teaching hospitals of Shiraz University of Medical Sciences from 2009 to 2011. Methods: The present study was descriptive ...
In addition to the building properties effect on energy consumption, it is important to consider occupant’s energy behavior and their interaction with building systems in energy calculations. According to studies, energy retrofit regardless of considering this factor, has a lower effect on reducing the energy consumption. This study investigates the impact of energy retrofit in two (retrofitted...
multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. in this paper, a new clustering based multi path routingprotocol namely ecrr (energy efficient cluster based routing algorithm for improving reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required qos ...

in the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. the importance of such energy optimization schemes stems from the environmental impacts of freon (r-12) used as the working refrigerant in household refrigerator – fre...
Background: Adequate nutritional status is a critical determinant of the onset and maintenance of normal reproductive function. More than 50% of women with PCOS are obese and central obesity plays a central role in the pathogenesis of PCOS by generating an insulin- resistant state, It has been proposed that recurrent hypoglycaemia due to hyperinsulinaemia could lead to decreased post-prandial s...
