The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...

Egypt is considered an arid country and depends mainly on the Nile River groundwater reservoirs to supply water for drinking various uses. The northwestern coastal zone one of regions that rely heavily rainwater irrigation. As a result changes in climate rise sea level, increase seawater intrusion growing. Furthermore, exploitation increased pumping some wells installed this area have negative ...

to better understand the potential for improving biomass accumulation and radiation use efficiency (rUE) of winter wheat under deficit irrigation regimes, in 2006–2007 and 2007–2008, an experiment was conducted at the luancheng Experimental Station of Chinese academy of Science to study the effects of deficit irrigation regimes on the photosynthetic active radiation (Par), biomass accumulation,...

Water management and utilization is an ongoing problem in developing countries with semi-arid to arid climates such as Afghanistan. The lack of effective irrigation systems are oftentimes the most limiting factor for maximizing agricultural productivity in these countries. In Afghanistan, the most widely used irrigation methods are basin/border for cereal crops and furrow for vegetables and gra...

Complicated pulmonary unilocular cystic hydatidosis (CPUCH) is a serious condition, which requires immediate treatment. The aim of the present study was to evaluate the efficacy of fibreoptic bronchoscopy (FOB) in the final diagnosis of CPUCH. Of 1,726 cases, who underwent FOB evaluation between 1990 and 1994 in our centre, 24 patients (17 females and 7 males), who had proven CPUCH after thorac...

A theory based on Manning roughness equation, Philip equation and water balance equation was developed which only employed the advance distance in the calculation of the infiltration parameters and irrigation coefficients in both the border irrigation and the surge irrigation. The improved procedure was validated with both the border irrigation and surge irrigation experiments. The main results...

PURPOSE The efficacy of antibiotic therapy for acute sinusitis is controversial. This study aimed to compare the efficacies of amoxicillin with nasal irrigation and nasal irrigation alone for acute sinusitis in children. METHODS This randomized, double-blind, controlled study included 80 children aged 4-15 years with a clinical presentation of acute sinusitis. Patients were randomly assigned ...

OBJECTIVE To determine whether avoiding intra-abdominal irrigation at cesarean delivery will decrease rates of intraoperative and postoperative gastrointestinal disturbance without increasing postoperative morbidity. METHODS This was a randomized controlled trial of patients undergoing cesarean delivery. Patients were randomized to irrigation after closure of the hysterotomy compared with no ...

Saline nasal irrigation is an adjunctive therapy for upper respiratory conditions that bathes the nasal cavity with spray or liquid saline. Nasal irrigation with liquid saline is used to manage symptoms associated with chronic rhinosinusitis. Less conclusive evidence supports the use of spray and liquid saline nasal irrigation to manage symptoms of mild to moderate allergic rhinitis and acute u...

Various irrigation regimes were applied to NC0376 over five years of low rainfall (average 466 mm per annum). Cane yield increased, depending on amount of water applied, from 84 to 122 t/ha. There was no significant effect on quality. The lowest application of 660 mm of irrigation produced 69% of the yield produced by the standard (full) irrigation (1 520 mm) at 12 months of age. There were no ...
