INTRODUCTION This randomized clinical study compared the antibacterial effects of irrigation with either 2.5% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) during the preparation of infected root canals with rotary nickel-titanium instruments. METHODS The root canals of 50 single-rooted teeth with apical periodontitis were prepared by using BioRaCe rotary instruments (FKG Dentaire, La...

This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...

In order to promote the efficient and coordinated utilization of water nitrogen in rice, the  15 N missing technology experiment was adopted study effects application rate (N 0 , 160 200 240 ) irrigation mode (Wet-dry alternation, conventional irrigation) on absorption, transport, residue, loss super rice. The results showed that with increase rate, accumulation fertilizer total rice plant...

This study aimed to design and implement a subsurface irrigation system using porous emitters of various materials such as bubblegum, flannel, cotton, spandex. It was carried out descriptive methods, namely designing, measuring, observing, calculating, analyzing data quantitatively. The results showed that the soil conductivity ranges from 1.0 3.01 cm3/hour, flannel material transmitter has max...

ABSTRACT Banana orchards in arid and semiarid regions require the use of irrigation. However, presence high concentration salts water can impair development plants, requiring evaluation new technologies to mitigate effects stress. The objective this study was evaluate gas exchange leaf area banana seedlings cultivar Prata Catarina inoculated with strains Bacillus spp. under different electrical...

the objective of deficit irrigation is to increase water use efficiency by reducing of water quantity or wave off further irrigations that have not necessary. cotton plant is sensitive to irrigation timing and quantity through different growth stages. the field trail was conducted at hashemabad cotton research station (gorgan) to determine water consumption and cotton sensitivity to deficit irr...

introduction cultivated alfalfa (medicago sativa l.) is the main, most of the time the only, forage for ruminants in iran as well as many other parts of the world. harvesting high quality forage is critical for iranian dairy industry, because it affects the performance of animals and reduces amount of concentrates utilization in dairy diets. unfortunately the most parts of the concentrates ingr...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...
