In the irrigated western U.S. disposal of drainage water has become a significant economic and environmental liability. Development of irrigation water management practices that reduce drainage water volumes is essential. One strategy combines restricted drainage outflow (by plugging the drains) with deficit irrigation to maximize shallow groundwater consumption by crops, thus reducing drainage...

dominal pain and jaundice for 2 months. Computed tomography (CT) revealed a huge mass at the pancreatic head causing distal common bile duct (CBD) obstruction with superior mesenteric vein and superior mesenteric artery encasement (●" Fig. 1). The man underwent endoscopic retrograde cholangiopancreatography (ERCP), but we could not pass the duodenoscope through the duodenum because of tumor inv...

Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...

For a railway or highway tunnel under high water pressure during operation, various factors such as the design of drainage system, material aging, and pipeline blockage must be considered for tunnels to work with parallel adit drain control external on lining. A simplified steady-state seepage model in semi-infinite multi-connected domain was established solved iteratively using complex variabl...

the management of water table is introduced as one of the major parts of the solutions in water resources management. this method could play a significant role in protecting water resources, increasing irrigation efficiency, preserving nutrients in soil, and protecting the quality of surface downstream, and as well, of groundwater. towards this end, a laboratory study has been done on the effec...

cushing’s syndrome is a rare endocrine disease characterized by hypercortisolemia caused by excess acth secreted by the pituitary. distinguishing pituitary sources from the ectopic sources of acth is challenging because of the limited accuracy of noninvasive assays. the test that offers the highest sensitivity and specificity is bilateral inferior petrosal sinus sampling (bipss). in patients wi...

regarding the role and importance of subsurface drainage in water table control, many studies have been made throughout the world to find out new techniques and more economical solutions, especially as related to different pipe envelope material and their installations. this research was conducted to investigate the use of rice husk, as drain envelope material, in drainage installations. in add...

Thirteen million [corrected] metric tons of poultry litter are produced annually by poultry producers in the U.S. Poultry litter contains the sex hormones estradiol and testosterone, endocrine disruptors that have been detected in surface waters. The objective of this study was to evaluate the potential impact of poultry litter applications on estradiol and testosterone concentrations in subsur...
