Background: 4-Chlorophenol is used frequently in industries including refineries petrochemical, industries pesticide industries and many others. This compound causes damage to environment. The purpose of this research was the survey of 4-chlorophenole degradation by Fe°/H2O2 of synthetic wastewater and resulting intermediate compounds. Methods: This study is an applied- experimental researc...
Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...
BACKGROUND Positions, signs, symptoms, and medical management of National Football League players with concussions involving 7 or more days out (7+) from play were compared for two 6-year study periods (2002-2007 vs 1996-2001). HYPOTHESIS More players were held out 7+ days in the 2002-2007 period without significant difference in concussion signs and symptoms. STUDY DESIGN Cohort. METHODS...

Probiotic is considered as a remedy to solve disease problem in shrimp aquaculture. Shrimp body and environment bacterial flora are recommended as reliable source for extracting of beneficial bacteria. Therefore, 5000 pieces of post larvae of Penaeus monodon were distributed equally in 4 tanks in probiotic and antibiotic free condition up to juvenile. Then microbiological samples from digestiv...
PURPOSE To report a case of unilateral total limbal stem cell (LSC) failure and corneal opacification secondary to thimerosal- and contact lens-induced ocular surface toxicity. METHODS Interventional case report and review of the literature on thimerosal-induced ocular surface changes. RESULTS A 49-year-old woman with a 2-year history of long-term soft contact lens wear developed unilateral...
