Significant changes in population and cultivation of farmland in Western U.S. over the past 200 years has required the use of extensive irrigation to sustain crop growth in the region. This irrigation has altered the land surface processes in the region and subsequently the local climates by increasing soil moisture levels higher than they naturally would be if no irrigation had taken place. An...

BACKGROUND To evaluate the effects of the amount of irrigation on heat generated during implant site preparation. MATERIAL AND METHODS Ten freshly dissected sheep mandibles were sectioned into 30 equal bone blocks and transferred into a heat-controlled water tank. Implant socket preparations were performed with four consecutive drills. Temperature measurements were performed with a thermocoup...

Drawing from the encouragement of Prof. Norman Uphoff to start SRI in Kenya, the first meeting to plan and introduce SRI was held at the Mwea Irrigation Scheme in July 2009, organized by Prof. Bancy Mati of JKUAT and Markus Moeller (then the Irrigation Specialist at the World Bank office in Kenya). The two drew together some like-minded individuals to form a collaborative team comprised of staf...

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 ...

Conflicts between water supply and water demand are intensifying in irrigation districts along the Lower Yellow River due to climate change and human activities. To ensure both adequate food supply and water resource sustainability in China, the Soil and Water Assessment Tool (SWAT) model was used to simulate the water balance and water use of agro-ecosystems in an irrigation district of the lo...

BACKGROUND Nasal irrigation has been used as adjunctive therapy for sinonasal disease but is under-researched in children. The study aim was to evaluate the effectiveness of nasal irrigation with normal saline in the management of acute sinusitis in atopic children. METHODS We enrolled 60 atopic children with acute sinusitis, of whom 29 received nasal irrigation with normal saline and 31 did ...

The study on ‘‘pro-poor intervention strategies in irrigated agriculture in Asia’’ by Hussain (2005) shows that, in 26 major and medium-size canal irrigation schemes in Asia, irrigated areas average 20% lower poverty than adjacent rainfed areas; gains are more with pro-poor management of water for farming (PPMWF) and where distribution of farmland or farm water is more equal. These findings, an...

introduction: maintaining soil moisture content at about field capacity and reducing water loss in near root zone plays a key role for developing soil and water management programs. clay pot or porous pipe is a traditional sub-irrigation method and is ideal for many farms in the world’s dry land with small and medium sized farms and gardens and is still used limitedly in dry lands of india, ira...

This paper develops the system of optimal allocation of water resources in irrigation district and irrigation decision support which integrates technologies of decision support, information management, information search and so on. It has the multi-function of water production function calculation, crop water requirement calculation, water resources optimal allocation and realtime amending the ...
