Novel flow apparatus for investigating shear-enhanced crystallization and structure development in semicrystalline polymers
An instrument to study the effects of shearing on the crystallization process in semicrystalline polymers is described. It can impose transient stresses similar to those encountered in polymer processing and provides in situ monitoring of microstructure development during and after cessation of flow. Box-like wall shear stress profiles ~rise and fall times under 50 ms with maximum wall shear st...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولdesign, development and test of apparatus to measurement of electrical resistance and impedance of fruit
electrical properties of fruits are accepted indicators for detecting fruit quality. electrical resistanceone reluctance can detect quality factors and are sensitive to variations in the concentration and stateof water. therefore, these properties can be associated with maturity, damage, overripe condition,decay or other quality factors. in most of previous research on electrical resistance and...
متن کاملO-10: Formation and Molecular Composition of The Sperm Head to Tail Coupling Apparatus
Background According to a worldwide survey in 2010 infertility affects 48.5 million of couples. In roughly half of the cases infertility is provoked by the male mate. Thus, a significant percentage of young men are infertile but the underlying causes are mostly unknown. Male fertility and reproduction success critically depends on proper formation of the mature sperm. Transmission of the geneti...
