In systems experiencing water scarcity and consequent intermittent supply, users often adopt private tanks that collect water during service periods and supply users when the service is not available. The tank may be fed by gravity or by private pumping stations depending on the network pressure level. Once water resources are collected, the tank can supply users by gravity if it is located on ...

In the absence of permanent rivers or bodies of water half of the Saudi Arabia domestic water consumption is provided through desalination. The other half is derived from groundwater. Groundwater from the Disi aquifer is already used for drinking water in parts of Jordan and, more extensively, in Saudi Arabia, where it is known as the Saq aquifer. Some of the geological analyses of the host san...

Abstract This research investigates the effect of drought on ground water table of Neishabour plain. The precipitation data of Nishabour synoptic station during 1990-2001, the Bar climatology station during 1964-2001 and the data of hydrometric stations of Kherv and Bar in 1996-2001 have been used as the base of analysis. The method of Herbest et all has been used to analyze the drought. Usin...

Introduction: Dehydration occurs when the body loses more water than you take in that is when the water balance is negative, it is shifted to water loss. It is often accompanied by changes in the balance of mineral salts or electrolytes in the body, especially sodium and potassium. It is aggravated by heat and swallowing problems. Today green smoothies are increasingly present in the diet of pe...

Wireless underground sensor networks (WUSNs) can enable many important applications such as intelligent agriculture, pipeline fault diagnosis, mine disaster rescue, concealed border patrol, crude oil exploration, among others. The key challenge to realize WUSNs is the wireless communication in underground environments. Most existing wireless communication systems utilize the dipole antenna to t...

The Modified Arkansas Off-Stream Reservoir Analysis (MARORA) model estimates the economics of on-farm reservoirs and other water conservation improvements in alternative ground water situations. With restricted ground water supply, a combination of different water conservation methods is estimated to provide the greatest economic return. On-farm reservoirs are not economical if ground water is ...

Changes in gravitational load have been shown to alter renal function, which could potentially affect water balance. Therefore, the present study was conducted to determine the effects of chronic centrifugation on water balance. Eight Sprague-Dawley rats were centrifuged (12 days at 2 G), and eight rats were used as a control group. Water balance over the course of the study was determined by q...

the arid zone encompasses land that has an imbalance between precipitation and losses through evaporation. globally, arid zones comprise large part of many countries in the mid-latitudes in both the northern and the southern hemispheres. both australia and iran are countries with a large arid zone. this negative water balance in the arid zone affects the type of land use in these countries. at ...
