In the recent years, renewable energy sources are an important component of world energy consumption. GDP is one of the main measures of a country’s economic activity. Most of the studies examine the impact of renewable energy consumption on GDP with single equation model and the others use dynamic panel data. Since the Granger causality analysis’s findings of this paper establish bidirectional...
background: in order to provide better advice for prevention of obesity and eating disorders among children, there is a need to have more knowledge of their dietary patterns. this study examined meal and snacking patterns of primary school children in tehran. methods: a total of 761 male and female primary school children from all educational areas in tehran were recruited in a cross‑sectional ...

From past few decades, reduction in energy consumption for wireless sensor networks had remained primary focus for researchers. In this paper, improved circular caching scheme has been proposed .The network has been simulated in MATLAB environment for given system parameters. Results are showing 10 % improvement in network battery life and 60% improvement in energy consumption in comparison wit...
Energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. In this paper, byusing the energy consumption data for the residential sector of Shiraz in Iran, the effect of built area (BA) andoccupant number (Occ) on annual energy consumption (Ec) w...
Among the most important factors affecting energy consumption in the building sector are social and economic conditions, the culture of energy consumption, geographical and climatic characteristics of a city, the role of a city, efficiency of energy supply and consumption systems, and physical/spatial parameters of buildings and residential fabrics. Addressing urban form through planning ...
Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...
Energy use in homes and buildings represents an important part of the load electrical systems [...]
In this study, an attempt is made to investigate the effect of energy consumption on environmental pollution in Iran. For this purpose, a basic model (the whole economy) and three sectoral models (household, commercial and public; industry and transportation) has been estimated with an autoregressive distributed lag approach in the period 1971-2017. The results of the model estimation show the ...
Despite significant effort to quantify the interdependence of the water and energy sectors, global requirements of energy for water (E4W) are still poorly understood, which may result in biases in projections and consequently in water and energy management and policy. This study estimates water-related energy consumption by water source, sector, and process for 14 global regions from 1973 to 20...
