The nonlinear electromigration of analytes into confined spaces.
We consider the problem of electromigration of a sample ion (analyte) within a uniform background electrolyte when the confining channel undergoes a sudden contraction. One example of such a situation arises in microfluidics in the electrokinetic injection of the analyte into a micro-capillary from a reservoir of much larger size. Here, the sample concentration propagates as a wave driven by th...
متن کاملElectromigration-induced propagation of nonlinear surface waves.
Due to the effects of surface electromigration, waves can propagate over the free surface of a current-carrying metallic or semiconducting film of thickness h(0). In this paper, waves of finite amplitude, and slow modulations of these waves, are studied. Periodic wave trains of finite amplitude are found, as well as their dispersion relation. If the film material is isotropic, a wave train with...
متن کاملthe effects of integrating cooperative learning into vocabulary learning of elementary school students
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
15 صفحه اولSemiflexible chains in confined spaces.
We develop an analytical method for studying the properties of a noninteracting wormlike chain (WLC) in confined geometries. The mean-field-like theory replaces the rigid constraints of confinement with average constraints, thus allowing us to develop a tractable method for treating a WLC wrapped on the surface of a sphere, and fully encapsulated within it. The efficacy of the theory is establi...
متن کاملUsing PIDs in confined spaces.
The industrial environment has changed substantially since OSHA first defined confined space entry (CSE) regulation in the late '70s, and gas detection regulation has not kept pace. The standard four-gas monitor is simply insufficient protection from the many--now common--toxic gases and vapors that are major constituents or byproducts of modern industrial processes. Monitors that measure only ...
