Manasi River basin is located in the north foot of Tianshan Mountain, south edge of Zhunger Basin, central-north Xinjiang province, with typical arid features of northern China. As the pressure on water resources in Manasi river basin is mounting because of rapid economic development, its conservation becomes ever more important. Climate change is another major threat to the future of water res...
The present study investigates the effectiveness of thermostat control strategy in cooling energy consumption in residential buildings. To evaluate the energy consumption, two scenarios including a residential zone with and without the thermostat control system are assumed. The TRNSYS software provides an efficient numerical tool to model and evaluate a cooling system. Furthermore, since solar-...

Nitrogen (N) uptake (kg ha-1) of field-grown potatoes was measured in 4.32 m2 lysimeters that were filled with coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for six weeks until final harvest. Results show...
Confronted by the population mushroomed and the increasing shortage of water around the world today, water-saving irrigation and intensive cultivation are inevitable and viable. In this paper, the auto water-saving irrigation based on wireless sensors networks and multi-source information fusion technology based on entropy is introduced. Using wireless sensors networks which adopts nRF2401 as t...
in this study, the optimization of energy consumption and reduction of greenhouse gas emissions of irrigated lentil production in esfahan province were conducted using data envelopment analysis (dea) method. the used data were collected randomly from 140 lentil producers using a face to face questionnaire method in the cropping season of 2014-2015. based on two dea models of constant returns to...
nsafe water is a global public health threat, placing persons at risk for a host of diarrheal and other diseases as well as chemical intoxication. Unsanitary water has particularly devastating effects on young children in the developing world. Each year, >2 million persons, mostly children <5 years of age, die of diarrheal disease (1,2). For children in this age group, diarrheal disease account...
Introduction: Nowadays, water has turned into one of the biggest challenges of the current century, which can be the origin of numerous positive and negative changes across the world. Iran is one of the driest countries with a quarter of the average annual precipitation on a global scale. Thus, the purpose of this study was to investigate the relationship between religious attitudes and tendenc...
