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...

BACKGROUND Transurethral resection of the prostate (TURP) involves the risk of transurethral resection (TUR) syndrome owing to hyponatremia. Irrigation fluid type, duration of operation, and weight of resected mass have been evaluated as risk factors for TUR syndrome. The purpose of the present study was to identify risk factors related to TUR syndrome in the elderly. METHODS After obtaining ...

this study was conducted to determine the appropriate irrigation interval on the basis of cumulative water evaporation from standard evaporation pan (class a) and to find out the effects of irrigation regimes on growth indices and on qualitative and quantitative yields of sugar beet. the experiment was conducted in 2005 at the lavark agricultural experiment station fields, isfahan university of...

drought stress is the most limiting factor of agricultural production through the world. to evaluate the effect of super absorbent and humic acid to reduce drought stress in sugar beet production, a strip split plot arrangement based on randomized complete block design with three replications was conducted at research field of faculty agriculture, ferdowsi university of mashhad, iran during gro...

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...

this study was conducted to evaluate the water-use efficiency of rice (khazar cultivar) at rasht research institute of rice. the treatments were four different irrigation intervals (two, five, eight and 11 days) in a randomized complete block design (rcbd) with three replications. the plot size was 15 square meters in area and 50 cm in depth. the spacing between plants was 25 x 25 cm and the so...

Irrigation management is based upon delivery of water to a crop in the correct amount and time, and the crop’s water need is determined by calculating evapotranspiration (ET) using weather data. In 1994, an ET-network was established in the Texas High Plains to manage irrigation on a regional scale. Though producers used the ET-network, by 2010 public access was discontinued. Why did producers ...

Saline irrigation has been shown to be both experimentally and clinically efficacious in decreasing bacterial contamination as well as decreasing infection rates. The dynamics of irrigation delivery fall into two primary categories: simultaneous and intermittent irrigation. An important component to irrigation therapy is distribution of irrigation solution to hard-to-reach areas of a wound bed,...
