Hydrocyclones are used as pre-filter to reduce suspended particles in irrigation water on the subsequent filters. The aim of study was determine separation efficiency (SE) hydrocyclones, called H1, H2 and H3 according inlet/outlet diameters, at velocities 1.0 (V10), 1.5 (V15) 2.0 (V20) ms-1, sands diameter 0.5 (D05), (D10), (D15), (D20) 2.5 (D25) mm. Therefore, a hydrocyclone laboratory test sy...

[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.

OBJECTIVE To compare intranasal distribution of saline solution delivered by three popular methods for nasal saline irrigation. STUDY DESIGN Prospective, controlled comparison. METHODS Eight healthy adult volunteers received nasal irrigation with 40 mL of isotonic, nonionic contrast material immediately before having coronal computed tomography to visualize distribution of solution in the p...

Water ionization is an efficient physical water treatment technology, and crop nutrient use efficiencies can be improved using ionized for irrigation. In order to explore the effect of on soil nitrification nitrifying microorganisms, we conducted a laboratory incubation experiment with addition ordinary under different contents (equal 30%, 60%, 100% 175% field capacity, θFC). During incubation,...

Abstract In most developing countries non-irrigation status often dominates adoption of traditional and modern irrigation technology. In this paper, we study the effect of production risk on irrigation technology choice among small-scale farmers in Chile, applying sample selection and discrete choice models. We find that more educated farmers, with credit access, receiving extension services, a...
