PURPOSE To develop an improved T2 prepared (T2 prep) balanced steady-state free-precession (bSSFP) sequence and signal relaxation curve fitting method for myocardial T2 mapping. METHODS Myocardial T2 mapping is commonly performed by acquisition of multiple T2 prep bSSFP images and estimating the voxel-wise T2 values using a two-parameter fit for relaxation. However, a two-parameter fit model ...

BACKGROUND AND PURPOSE Switching of magnetic field gradients is the primary source of acoustic noise in MR imaging. Sound pressure levels can run as high as 120 dB, capable of producing physical discomfort and at least temporary hearing loss, mandating hearing protection. New technology has made quieter techniques feasible, which range from as low as 80 dB to nearly silent. The purpose of this ...

in order to study of effects of integrated biological and chemical  fertilizers on  fertilizer use efficiency, grain yield and related traits to  grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...

In this research, White spot syndrome virus (WSSV) with 105.4LD50.mL-1 inactivated with gamma irradiation at a dose rate of 14-15 kGy.sec-1 was used as a vaccine. Three hundred and sixty shrimp of Litopenaeus vannamei, medium body weight (MBW) 1.0±0.17g), were prepared and experimentally exposed. They were distributed among four groups, inclusing vaccinated-virus exposed (T1), vaccinated-nonvir...

OBJECTIVE To assess the reliability of kinematic, mechanical and energetic gait variables at short (1 day) and medium (1 month) intervals in adult patients after stroke. DESIGN Prospective study. SUBJECTS Ten patients with chronic post-stroke (mean age 53.5 years; age range 25-80 years). METHODS Three-dimensional gait analysis was performed 3 times in these subjects: at baseline (T0), aft...

The objective of this study was to investigate the impact stimulating embryo during dormancy in incubation period. 450 eggs (Ross 308) were allocated four treatments each with three replicates. as follows: T1 control (without shock), T2 Shocked (40) Millivolts (mV), T3 (50) T4 (75) (mV). A different voltage device used shock egg, after marking a line iron filings ensure electrical conductivity,...

a study was conducted to evaluate the effect of feeding different levels of protein to black baladi breed kids. weanling baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. kids were divided randomly to one of the three treatments for 12 weeks. the three dietary treatments were: t1: control ration, formulated according to nrc to cover the protei...

Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment gr...
