in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...

for any educational program to be successful, many factors work hand in hand. based on pervious efl studies, teachers and learners are the keys to gain achievement. granted the fact that explicit and implicit practice plays a key role in education, knowledge of it can help teachers facilitate students’ vocabulary learning. this study investigated to determine the contribution of explicit and i...

Background and Aim: Nonalcoholic fatty liver disease is the most common cause of abnormal liver enzymes. We aimed to investigate the effects of of resistance and combined exercise on levels of liver enzymes in women with fatty liver disease Materials and Methods: In this study, 37 women were assigned into three groups including control, resistance and combined exercise groups. Resistance exerci...

Objective: The purpose of this study was to investigate the study of shooting accuracy and fatigue of leg muscles after eight weeks of resistance training in shooters men with a Inflatable pistol. Methods: The statistical population of elite male shooters was Kohgiluyeh and Boyerahmad provinces. The sample consisted of 20 subjects who were randomly divided into two groups. The data were analyz...

The purpose of this study was to evaluate the effect of 6 weeks of core stability training on the balance of mentally retarded. Our subjects included 31 male mentally retarded students in two groups (control, 14 patients with a mean age of 11/07±3/02years, height 152±7/86cm) and (17experimental group with a mean age 11/23 ± 1/95years, height 147±7/07cm) and were A group of healthy students (15 ...

Introduction: After resistance and aerobic training session are decreased mean resting blood pressure. Therefore is expected that concurrent training session had additive effects on hypotension. The aim of this study was to investigate hemodynamic responses after aerobic training session (ATS), strength training session (STS), and concurrent training session (CTS) in untrained, overweight young...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
