CHLOROTHIAZIDE administration in normotensive and hypertensive individuals causes saluresis, diuresis, oligemia, increased depressor responses to ganglioplegics, and decreased pressor responses to norepinephrine."" These changes in responses to vasoactive drugs are abolished if plasma volume is expanded by salt-free dextran,^* and we have suggested that they reflect an augmented sympathetic vas...

Shallow water tables near-streams often lead to saturated, overland flow generating areas in catchments in humid climates. While these saturated areas are assumed to be principal biogeochemical hot-spots and important for issues such as non-point pollution sources, the spatial and temporal behavior of shallow water tables, and associated saturated areas, is not completely understood. This study...

The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...

We examined the effects of hypotension and fluid depletion on water and sodium ingestion in rats in response to intracerebroventricular infusions of ANG II. Hypotension was produced by intravenous infusion of the vasodilator drug minoxidil (25 microg x kg(-1) x min(-1)) concurrently with the angiotensin-converting enzyme inhibitor captopril (0.33 mg/min) to prevent endogenous ANG II formation. ...

Proteins that bind intracellularly are surrounded by other macromolecules. Macromolecular crowding has been shown to impact protein folding and binding, but its effects on the electrostatics of protein binding have not been thoroughly studied. Two ways crowding can affect binding are via loss of water mobility and water depletion. Crowding causes loss of water mobility because more water molecu...

controlled drainage is one of the strategies to reduce negative environmental effects in conventional drainage systems. this study examines the effect of controlled drainage on quality and quantity of drainage water, specifically amounts of salt and nitrate in drainage water, and nitrate uptake by maize (sc 704) with sandy loam soil texture in karaj. the experiment was performed as a randomized...

Being able to identify riparian sites that function better for nitrate removal from groundwater is critical to using efficiently the riparian zones for water quality management. For this purpose, managers need a method that is quick, inexpensive, and accurate enough to enable effective management decisions. This study assesses the precision and accuracy of a simple method using three ground wat...

Aquifer overexploitation could significantly impact crop production in the United States because 60% of irrigation relies on groundwater. Groundwater depletion in the irrigated High Plains and California Central Valley accounts for ~50% of groundwater depletion in the United States since 1900. A newly developed High Plains recharge map shows that high recharge in the northern High Plains result...

In the study, Drainmod model was used to compare measured water table depth fluctuations on the farm with those simulated by the model, also comparison of measured drainage outflow of the farm drains and model simulated was investigated. This study was made in a part of the Irrigation and Drainage Network of ABADAN Date palms. By statistical analysis of the measured and predicted water table de...
