Emitter clogging for using agricultural wastewater increases the operating costs and reduces the motivation of farmers. The new method to reduce the emitters clogging is the use of a Merus ring that does not have the problems of chlorination and pickling methods, such as pollution and high cost. Due to the importance of agricultural wastewater use, this study investigated the emitters clogging ...
Introduction:The use of beta emitters is one of the effective methods for palliation of bone metastasis. The risk of normal tissue toxicity should be evaluated in the bone pain palliation treatment. Methods: In this study, the Monte Carlo simulation code MCNPX was used for simulation a bone phantom model consisted of bone marrow, bone and soft tissue. Spe...
In this study, proton-irradiated tungsten targets, up to 2.6 GeV, were investigated for the purpose of experimental cross-section measurements. Radiochemical separation methods applied isolate residual long-lived alpha-emitters 148Gd, 154Dy, and 146Sm beta-emitters 129I 36Cl from targets. The molecular plating technique has been prepare samples alpha-spectrometry. Production cross-sections dete...
Drip irrigation is a new method of irrigation that is rapidly growing in different countries. The emitters are the most important parts of a drip irrigation system. Many factors such as physical, chemical and biological clogging, pressure, water temperature affect the emitter´s uniformity of water emission. In this study, to investigate pressure effect on the hydraulic performance of emitters, ...
We investigated four commercially available liquid scintillators as to overall counting efficiency and quenching effect of added phosphate-buffered isotonic saline. They differed significantly in these respects. Evidently, characteristics of the scintillator used in radioimmunoassays where beta-particle emitters are counted should be carefully examined if results are to be optimal.
Water crisis is an important issue in arid and semi-arid regions like Iran. The situation has been getting more worse over recent years drought. Hence, there is a growing need to utilize low quality water where freshwater is scarce. In this regard, urban wastewater is a promising source but there are concerns about the environmental and health aspects of using such water. The main problem regar...
