Soft Computing tools are becoming very popular in solving hydrological problems. These tools have immense strength to deal with such complex problems. Water Table elevation estimation is an important aspect to understand the mechanism of ground water resources. The present study aims at the application of Artificial Neural Networks (ANN) & Fuzzy logic for simulation of water table elevation. Th...
QUESTION How does water compare with other solutions for cleansing wounds? REVIEW SCOPE Included studies compared water with other solutions for cleansing acute or chronic wounds or with no cleansing and reported objective outcome measures. Studies assessing cleansing solutions as part of dental procedures, prophylaxis, preoperative or operative procedures, and those of patients with burns or u...
Water transfers from agricultural to urban and environmental uses will likely become increasingly common worldwide. Many agricultural areas rely heavily on underlying groundwater aquifers. Out-of-basin surface water transfers will increase aquifer withdrawals while reducing recharge, thereby altering the evolution of the agricultural production/groundwater aquifer system over time. An empirical...
BACKGROUND Water ingestion raises blood pressure substantially in patients with perturbed autonomic control and more modestly in older subjects. It is unclear whether prophylactic water drinking improves orthostatic tolerance in normal healthy adults. METHODS AND RESULTS Twenty-two healthy subjects, 18 to 42 years of age, with no history of syncope underwent head-up tilt-table testing at 60 d...
brought under any medical treatment. The practice is a good one, and I would advocate its continuance and extension. Ammonia is a powerful stimulant and may do good?it cannot do any harm ; administered in doses of ten or fifteen drops with half a wine glass (chittack) of water, every quarter of an hour, or even more frequently, it may be of benefit; and, as in tho police stations and elsewhere ...
Acknowledgments First of all, I would like to thank God for giving me good health and patience to complete this work. I would foremost like to thank my family and close friends who have always given me unlimited support and encouraged me through this effort. This thesis is also dedicated to my deceased mother who has given me her protection from heaven. Special acknowledgment is also dedicated ...
Bi-level drainage system is a type of underground drainage systems, in which adjacent drainage lines are installed at different depths. In the Hydraulics Laboratory, Ferdowsi University of Mashhad, a model was built, that include a cube tank 2 meters in length, width and height of 1 meters was made of galvanized. In this model, two rows 20 cm apart from each other drains were installed. As dr...
Prosopis tamarugo Phil. is a strict phreatophyte tree species endemic to the "Pampa del Tamarugal", Atacama Desert. The extraction of water for various uses has increased the depth of the water table in the Pampa aquifers threatening its conservation. This study aimed to determine the effect of the groundwater table depth on the water relations of P. tamarugo and to present thresholds of ground...
In this paper it is presented the real time monitoring system of water flow in hydro power plants which is designed with virtual instrumentation software. Water flow through penstock has been measured by using flow sensor. Volumetric flow of excess water, in the case of emergency evacuation of water, has been calculated from position of control gates and water level. Relationship between the vo...
Field and laboratory observations have shown that a relatively low beach groundwater table enhances beach accretion. These observations have led to the beach dewatering technique (artificially lowering the beach water table) for combating beach erosion. Here we present a process-based numerical model that simulates the interacting wave motion on the beach, coastal groundwater flow, swash sedime...
