Inter- and Intrachain Associations of an Ethylene-Vinyl Acetate Random Copolymer in Dilute 1,2-Dichloroethane Solutions
Laser light scattering (LLS) has been used to study an ethylene-vinyl acetate (EVA) random copolymer in 1,2-dichloroethane. The EVA solution was treated using two different thermal processes: (1) quickly quenching from 70 °C to 0 °C; and (2) slowly cooling from 70 °C to room temperature and annealing at room temperature for 24 h before further quenching to 0 °C. The LLS results reveal the forma...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولBTEX detection with composites of ethylenevinyl acetate and nanostructured carbon
By using a solvent-based method composites of ethylenevinyl acetate copolymer and carbon black (EVA-CB) were synthesized for sensing BTEX (benzene, toluene, ethylbenzene and xylene) vapours. The composites were characterized using atomic force microscopy (AFM) in an electroconductive mode. Gas sensing results show that EVA-CB can reproducibly detect BTEX and that the response increases linearly...

an investigation into iranian teachers consistency and bias in evaluation of students writings
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
