A field experiment was conducted to evaluate the residual effect of rock phosphate and waste mica enriched compost on phosphorus and potassium supplying capacity under soybean crop grown after wheat in a Typic Haplustept. Enriched compost prepared using rice straw, rock phosphate, waste mica and Aspergillus awamori had higher chemical (total P, K, Ca, Mg and micronutrients) as well as biologica...

background: the aim of this study was to investigate clinical applications of mobile c-arms and consequent radiation risk,to increase medical attention on radiation protection, and to provide basic data for safe radiation use in the operating room. materials and methods: in this study, a total of 374 surgical operations, conducted using a portable fluoroscopic x-ray system from january to march...

introduction the purpose of this study was to estimate organ and effective doses in patients undergoing some common x-ray examinations in sabzevar, iran. the effective dose is one of the best parameters for describing the amount of radiation dose received by a patient undergoing any diagnostic x-ray examination. the public dose from x-ray examinations depends on various factors, and its contrib...

Background: Iodine brachytherapy sources with low photon energies have been widely used in treating cancerous tumors. Dosimetric parameters of brachytherapy sources should be determined according to AAPM TG-43U1 recommendations before clinical use. Monte Carlo codes are reliable tools in calculation of these parameters for brachytherapy sources. Materials and Methods: Dosimetric param...

Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize w...

to evaluate the effect of reduced doses of foramsulfuron and nitrogen rates on weed biomass in corn field, an experiment was conducted using split plots arrangement based on randomized complete block design with three replications at research field of ferdowsi university of mashhad, in 2011. main plots were weed control levels comprising three reduced herbicide doses of foramsulfuron (50, 75, a...

background: patient radiation doses from computed tomography (ct) are increasing due to the number of ct examinations performed every day. the aim of this study was assess and evaluate patient radiation doses for adult’s common ct examinations to derive local diagnostic guidance levels for common ct examinations. materials and methods: volume and weighted computed tomography dose index (ctdivol...

a field study was conducted to evaluate the effect of haloxyfop-r-methyl ester doses in different grass weeds in various growing stages in safflower during 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried our as split split plot based on randomized complete block design with three replicates. the main factor, sub factor and sub sub fa...

ct.scan examinations cause high patient absorbed dose from x-ray ionizing radiation. therefore it is necessary to obtain superficial dose profile in z-line. in this research 11 thermoluminecent dosimeter (tld), after calibration were located on z line perpendicular to slice thickness. ct.scan machines did x-ray exposures. the resultant dose profiles showed gussian shape apperience, which has se...

background: a study has been conducted to assess two useful radiation protection indices, the annual per-capita effective dose equivalent (aed) and the genetically significant dose (gsd), from conventional diagnostic radiography in 10 counties with more than 1,886,000 inhabitants in khorasan province in iran. materials and methods: the health centre authorities of khorasan province were asked t...
