The design and implemental plan of the farmland irrigation remote monitoring system with variable frequency and constant pressure based Configuration Software and multiple serial port communication were introduced. The implementation of the communication between inverter, PLC, ADAM and KingView was studied. The data acquisition and monitoring scheme were analyzed. The hardware and software desi...

The use of indicators for sustainability evaluation is an important step towards operationalization of the concepts of sustainability and sustainable development. Many literatures on framework for sustainable water management consider any one dimension of sustainability. In this paper, the sustainability of an irrigation system is assessed from economic and environmental dimension. An optimizat...

Irrigation with moderately saline waters may provoke soil salinization and sodification. The objectives of this three-year study were (1) to quantify these processes in two seedless table grapevines (Vitis vinifera cvs. Autumn Royal and Crimson) subject to a full irrigation and two regulated deficit irrigations (RDI, irrigated at 80% and 60% of net irrigation requirements from post-veraison til...

Realizing the internal flow visualization inside the drip irrigation emitter is the basis of optimizing the labyrinth path structure and promoting its anti-clogging capability. The Computational FluidDynamics (CFD)method has become an effective approach to research the water movement in the labyrinth path of the drip irrigation emitter. In this paper, the standard k-ε model and the Large Eddy S...

OBJECTIVES In this study we evaluated heat generation during the low-speed drilling procedure without irrigation. MATERIALS AND METHODS Ten artificial bone blocks that were similar to human D1 bone were used in this study. The baseline temperature was 37.0℃. We drilled into 5 artificial bone blocks 60 times at the speed of 50 rpm without irrigation. As a control group, we drilled into an addi...

The adoption of improved surface irrigation design and management practices is inhibited both by a low awareness amongst irrigators of the variables affecting irrigation performance and the difficulty of quantifying the benefits associated with alternative practices. Simulation modelling may be used to address both of these issues. This paper reports on the use of the surface irrigation model S...

BACKGROUND Although surgeons acknowledge the importance of irrigating open fracture wounds, the choice of irrigating fluid and delivery pressure remains controversial. Our objective was to clarify current opinion with regard to the irrigation of open fracture wounds. METHODS We used a cross-sectional survey and a sample-to-redundancy strategy to examine surgeons' preferences in the initial ma...

the aim of this study was to assess the efficacy of apical negative pressure (anp), manual dynamic agitation (mda), passive ultrasonic irrigation (pui) and needle irrigation (ni) as final irrigation activation techniques for smear layer removal in curved root canals.mesiobuccal root canals of 80 freshly extracted maxillary first molars with curvatures ranging between 25° and 35° were used. a gl...
