* Corresponding author. [email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

METHODS: PubMed was searched for publications from January 1 of 2000 through October of 2015. Studies with the following criteria were included: primary breast augmentation with implants; use of antimicrobial irrigation; and documentation of capsular contracture. Our primary outcome was incidence of capsular contracture. The quality of included studies was assessed independently. Studies were m...

BACKGROUND Systematic reviews support nasal saline irrigation for chronic or recurrent sinus symptoms, but trials have been small and few in primary care settings. Steam inhalation has also been proposed, but supporting evidence is lacking. We investigated whether brief pragmatic interventions to encourage use of nasal irrigation or steam inhalation would be effective in relieving sinus symptom...

In this study, the effect of deficit irrigation with every–other furrow irrigation method, which is an innovated method in farm irrigation management, was examined on sorghum (Sorghum durra L.) in Bajgah and Kooshkak areas of Fars Province. The experimental design was split plot with three main plots of irrigation interval (10, 15 and 20 days), three subplots of irrigation methods (ordinary fur...
