water shortage is the most important factors on crop production in the world. several methods of deficit irrigation are solutions for reduction of irrigation water. to understand the effects of conventional deficit irrigation and partial root zone drying treatments on yield, yield components and water use efficiency of sunflower (farrokh cultivar), one study was carried out. the research was co...

in order to evaluate yield and yield components properties of cold-tolerant chickpea under winter sowing and complementary irrigation conditions, two experiments in the context of partial balanced block design with 81 chickpea genotypes and three replications were carried out. complementary irrigation was performed during growing season including irrigation immediately after sowing, 20 days aft...

OBJECTIVE To compare the disinfecting efficacy of the sodium hypochlorite irrigation by root canal preparation with stainless steel hand files, taper 0.02 and nickel-titanium Mtwo files with taper 0.04-0.06. STUDY DESIGN 40 extracted human teeth were sterilized, and then inoculated with Enterococcus faecalis (ATCC 29212). After 6 day incubation time the root canals were prepared by hand with ...

OBJECTIVES The present in vivo study was designed to assess the efficacy of 3 root canal disinfection protocols in immature dog teeth with apical periodontitis (AP). MATERIAL AND METHODS Forty immature premolars with pulp necrosis and AP of five Beagle dogs were used. Three experimental disinfection protocols were established. After irrigation with 40 ml 5.25% sodium hypochlorite using the En...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...

The purpose of this paper is to outline the leading role the Electrical Engineering Department at Manchester played in the early development of control engineering teaching and research in the UK after the war. The holding of a major UK conference in Control Engineering in Manchester roughly 60 years after the start of this work seems an appropriate time to remind today’s researchers of these e...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

Wastewater irrigation is associated with several benefits but can also lead to significant health risks. The health risk for contracting infections from Soil Transmitted Helminths (STHs) among farmers has mainly been assessed indirectly through measured quantities in the wastewater or on the crops alone and only on a limited scale through epidemiological assessments. In this study we broadened ...

The present in vivo study was designed to evaluate the efficacy of apical negative pressure irrigation (ANP), passive ultrasonic irrigation (PUI) and positive pressure irrigation (PP) in the reduction of intracanal bacteria of dogs' teeth with pulp necrosis and apical periodontitis. Eighty root canals were randomly distributed into 3 experimental and 2 control groups according to the irrigation...

The objective of this field study was to determine the therapeutic efficacy of mammary irrigation for the treatment of dairy cattle diagnosed with acute coliform mastitis caused by gram-negative bacteria. Additionally, the effects of different mammary irrigation regimen fluids such as ozone water and normal saline were compared. Dairy cattle clinically diagnosed with acute coliform mastitis (n ...
