recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. here we appliedcathodic electrochemical deposition (ced) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (spions). in first step, bare fe3o4 n...

abstract infiltration is one of the most important phenomena which is affected by the soil physical and hydraulic characteristics. measurement of infiltration needs the high cost and is time consuming, therefore estimation of infiltration is necessary. also, due to variability of soil moisture, it is important to determine the appropriate model for the estimating the infiltration rate. the pres...

background: hepatitis b virus (hbv) vaccination is a well-known, safe and effective way for protection against hbv infection; however, non-responders remain susceptible to infection with hbv. this is so important in patients with any kind of chronic liver disease, especially chronic hepatitis c virus (hcv) patients in whom acute hbv infection may lead to decompensation of liver disease. some of...

background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...

Growth and carcass measurements were made on 2,411 Hereford steers slaughtered at a constant weight from a designed reference sire program involving 137 sires. A second data set consisted of ultrasound measures of backfat (USFAT) and longissimus muscle area (USREA) from 3,482 yearling Hereford cattle representing 441 sires. Restricted maximum likelihood procedures were used to estimate genetic ...

Three experiments were conducted to evaluate lysine (Lys), threonine (Thr), methionine (Met), tryptophan (Trp), and nonessential N (+N) supplementation of all sorghum grain (S) diets on growth and carcass characteristics of 50- to 100-kg pigs. In Exp. 1, four replicate pens of four pigs each were fed: 1) sorghum-soybean meal positive control (S-SBM); 2) S + Lys + Thr + Met + Trp to equal the am...

isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. among the non-tuberculous mycobacteria, these tests are unable to differentiate m. scrofulaceum from m. avium-intracellulare (mai) because of their identical biochemical characteristics. for this reason, one hundred mycobacterial strains suspected to be m. sc...

acquaintance with the different anatomical variations of the arterial supply of the gallbladder is of great importance in hepatobiliary surgical procedures. a rare variation of the hepatobiliary arterial system was found during anatomical dissection of a female iranian cadaver. two cystic arteries were present, the first arising directly from the right hepatic artery and the second from the gas...

background: hepatitis b virus potentially accelerates graft rejection and mortality in renal transplantation population. vaccination of graft candidates without prior immunization against hbv seems essential before transplantation but some candidates of transplantation have not received hbv vaccine at the time of receiving graft. we aimed to evaluate immunogenicity of an enhanced regimen (4 dos...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...
