this study examines technical efficiency in iran's banking system using unbalanced panel data for 17 state and private banks during the 1997-2009 period. therefore, technical efficiency of banks was measured through estimating a translog cost function in the form of a panel sfa error compound model. then, the effect of underlying factors including both individual and structural (ownership/...
Seventy-one patients with achalasia were studied. They were 2-29 years old. Dysphagia to solid food was the main presenting symptom (100 percent). Reliable and persistent manometric findings were absence of normal contraction waves in association with the presence of low amplitudes simultaneous waves in all cases. In vigorous achalasia, weight loss (P=0.001), dysphagia (P=0.012) and LES pressur...
Background and Objectives: Phenol is a toxic and persistent substance in the environment. The aim of this study was to evaluate the performance of silica aerogel synthesized using sodium silicate in the adsorption of phenol from aqueous solutions. Material and Method: Silica aerogel was prepared by Sol-Gel process. The influence of effective variables such contact time, initial pH of the sol...
Prognostic Significance of the Oxygen Uptake Efficiency Slope: Percent-Predicted Versus Actual Value
introduction: diabetes mellitus and osteoporosis are two frequent medical conditions with an increasing prevalence in elderly. this study is conducted to evaluate osteoporosis in postmenopausal females with type 2 diabetes mellitus in sanandaj, the provincial center of kurdistan province in the west of iran. methods: from an initial population of 2500 women with type 2 diabetes, 242 postmenopau...
Environmental Health Perspectives • volume 121 | number 7 | July 2013 A 209 Erratum: “A Physiologically Based Pharmacokinetic Model for the Assessment of Infant Exposure to Persistent Organic Pollutants in Epidemiologic Studies” Verner et al. have reported an error in their article “A Physiologically Based Pharmacokinetic Model for the Assessment of Infant Exposure to Persistent Organic Polluta...
BACKGROUND Transformation from persistent to paroxysmal atrial fibrillation (AF) after ablation suggests modification of the underlying substrate. We examined the nature of initial arrhythmia recurrence in patients with nonparoxysmal AF undergoing antral pulmonary vein isolation and nonpulmonary vein trigger ablation and correlated recurrence type with long-term ablation efficacy after the last...
Background and Objectives: Bakery’s yeast industry wastewater contains various pollutants and is generally characterized with high chemical oxygen demand (COD), dark color, high-nitrogen and sulfate and non-biodegradable organic pollutants. Having persistent soluble colored compounds (called melanoidins), effluent from yeast industry is a major source of water and soil pollution. The aim of thi...
due to limitation of conventional water resources, the use of unconventional water for agriculture is unavoidable. therefore, in order to investigate the effect of using different amounts of municipal wastewater on yield, yield components and water use efficiency of cotton in drip irrigation systems, a field experiment was carried out during 2010 and 2011 growing season at experimental farm of ...
