Introduction This study aimed to compare the effectiveness of two activated irrigation techniques in removing the smear layer after single-file reciprocating instrumentation in curved canals. Materials and Methods Sixty distobuccal roots of maxillary molars were standardized to create a closed system, and then instrumented using WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) in...

BACKGROUND Although the use of potable water for wound irrigation is attractive in an austere environment, its effectiveness has not been tested. We sought to compare the effectiveness of potable water irrigation in reducing bacterial number with that of normal saline irrigation. METHODS We used an established caprine model involving the creation of a reproducible complex musculoskeletal woun...

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 basic system dynamics model for collective irrigation management is proposed, which is aimed at improving the understanding of dynamic processes in collective irrigation systems. In particular, the problem of free-riding on water in irrigation systems is addressed. A feedback system is introduced, which builds on the concept of a critical mass and integrates a number of influence factors that...

Abstract. Based on the problems caused by current automatic irrigation system with a large number of cables, such as installation, maintenance, and difficult expansion, this paper proposed a wireless integrated irrigation control system and developed a wireless intelligent valve controller which can satisfy the requirements for agricultural irrigation in our country. The controller consisted o...

to evaluate the effects of biological phosphorous, chemical fertilizers and limited irrigation regime on quantitative and qualitative characteristics of two different grain sorghum cultivars (kimiya and speedeh), this experiment was conducted in research farm of college of agriculture, university of tehran during 2009 growing season. the experimental treatments were arranged as split split plot...

The Australian Government is meeting the challenge of water scarcity and climate change through significant on-farm infrastructure investment to increase water use efficiency and productivity, and secure longer term water supplies. However, it is likely that on-farm infrastructure investment will alter energy consumption and therefore generate considerable greenhouse gas (GHG) emissions, sugges...

The primary source of plant parasitic nematodes in irrigation waterways in the Columbia Basin Project of eastern Washington is irrigation runoff returned into the irrigation system. This has contributed to the rapid spread of plant parasitic nematodes observed during eight years of study.

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...
