Shallow groundwater is often exposed to multiple sources of pollution that can make it unsuitable for certain uses. Complete hydrogeochemical studies are necessary the better management these resources. Well water samples were collected on extent Karfiguéla paddy field physico-chemical parameters, such as pH, EC, TDS, Na+, Ca2+, Mg2+, K+, NH4+, NO3−, NO2−, SO42−, CO32−, Cl−, and HCO3−, metallic...
BACKGROUND AND PURPOSE Cisternal irrigation therapy with urokinase (UK) was performed in multiple institutions to prevent symptomatic vasospasm. The efficacy and safety of this therapy were evaluated, and the optimal concentration of UK was estimated. METHODS This therapy was performed in 28 patients who underwent surgery within 72 hours of the onset of severe subarachnoid hemorrhage (Fisher'...
The California lettuce and leafy greens industry has adopted the Leafy Greens Marketing Agreement (LGMA), which allows for 126 most-probable-number (MPN) Escherichia coli per 100 ml in irrigation water. Repeat irrigation of baby spinach plants with water containing E. coli O157:H7 and different levels of total organic carbon (TOC) was used to determine the epiphytic survival of E. coli O157:H7....
Improving irrigation water management is becoming important to produce a profitable crop in South Texas as the water supplies shrink. This study was conducted to investigate grain yield responses of corn (Zea mays) under irrigation management based on crop evapotranspiration (ETC) as well as a possibility to monitor plant water deficiencies using some of physiological and environmental factors....
abstract one of the problems in design of irrigation structures is sedimentation control in the inlet to the irrigation networks. water quality for agriculture requires that the sediments be controlled and reduced to the permissible limit at their entrance point to the turnouts and irrigation networks. this is possible by constructing a sedimentation basin. the bigger the basin, the best the re...
This project proposed an embedded system for automatic mist irrigation for cardamom field, which has a wireless sensor network for real time infield sensing and control of an irrigation system. This wireless system supports the cardamom field which has both plain and slope areas. Too much watering causes diseases to cardamom. This system provides uniform and required level of water for both pla...
BACKGROUND The review aimed to compare the effectiveness, safety and acceptability of vasectomy techniques for male sterilization. METHODS We searched five computerized databases and reference lists of relevant articles and book chapters for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing vasectomy techniques. Two reviewers independently extracted data from...
We review the properties of neutron matter in low-density regime. In particular, we revise its ground state energy and superfluid pairing gap analyze their evolution from weak to strong coupling The calculations are performed, respectively, within Brueckner–Hartree–Fock (BHF) approach nuclear Bardeen–Cooper–Schrieffer (BCS) theory using chiral nucleon-nucleon interaction Entem Machleidt at N 3 ...
