a two-year field experiment was carried out in semi-arid region of southern iran (shiraz), during 2007-2008 and 2009-2010 growing seasons using various mixtures of an early- (cv falat) and a middle-ripening (cv shiraz) winter wheat cultivar to evaluate the beneficial effects of inducing temporal growth heterogeneity on reduction of intra-specific competition during post-anthesis moisture stress...

The present work derives the exact analytical solutions for buckling and post-buckling analysis of nano-composite beams reinforced by single-walled carbon nanotubes (SWCNTs) based on the Euler-Bernoulli beam theory and principle of virtual work. The reinforcements are considered to be aligned in the polymeric matrix either unifor...

this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...

Objective: In the current investigation, we aimed to study the combined cytotoxicity of curcumin, as a nanomicellar formulation, and galbanic acid (Gal), dissolved in DMSO against the murine C26 and human Caco-2 colon carcinoma cells. Further, curcumin potential for cisplatin and doxorubicin (Dox) co-therapy was studied. <span styl...

This article presents psychometric characteristics of the UCLA PTSD Reaction Index for DSM IV (PTSD-RI) derived from a large sample of children and adolescents (N = 6,291) evaluated at National Child Traumatic Stress Network centers. Overall mean total PTSD-RI score for girls was significantly higher as compared with boys. Age-related differences were found in that overall mean total PTSD-RI sc...

introduction: tympanoplasty is indicated to restore hearing disability and prevent recurrent otorrhea.  materials and methods: this study was a retrospective review of patients who underwent tympanoplasty with or without mastoidectomy over a 1-year period.  results: a total of 789 tympanoplasties were reviewed, with a male-to-female ratio of 1:1.1. in total, 91% and 9% of tympanoplasties were p...

OBJECTIVE To examine whether there is a relationship between psychological stress in the family and obesity in 5- to 6-year-old children. STUDY DESIGN A total of 7443 Swedish families reported on psychological stress across 4 domains as part of the prospective All Babies in Southeast Sweden-project (ABIS). Domains assessed included serious life events, parenting stress, lack of social support...
