We have evaluated the voltage dependence and unitary conductance of gap junctional channels that were recorded in a clone isolated from the hepatoma cell line SKHep1. In this clonal population (designated SKHep1A), Northern blots, immunoprecipitation, and immunohistochemical staining demonstrated the expression of connexin (Cx) 45; no other gap junction protein was identified by these technique...

electrokinetic remediation is one of the most promising in situ or ex situ processes for decontamination of heavy metals, anions and polar organic compositions from the soil. in this study, we investigated the efficacy of this method in removing mercury from clayey soil (with kaolin to sand weight ratio of 2:1) and from gold mine tailing dam sediment and determined optimum removal conditions. t...

In this paper, static and dynamic behavior of a varactor of a micro-phase shifter under DC, step DC and AC voltages and effects of the residual stress on the phase diagram have been studied. By presenting a mathematical modeling, Galerkin-based step by step linearization method (SSLM) and Galerkin-based reduced order model have been used to solve the governing static and dynamic equations, resp...

welding produces residual stresses and distortion, having detrimental effect on structure integrity and service performance of the welded pipe joints. this paper investigates residual stresses and distortion during gas metal arc welding (gmaw) of pipes of schedule 40 and 60, nominal diameter 100mm and 200mm and thickness 8mm and 10mm with ansi flanges of class 300#. welding parameters including...

| This paper describes the principle and the design of a 0.5m CMOS, low-power, low-voltage, chopped ampliier for noise and ooset reduction in mixed analogue digital applications. The operation is based on chopping and dynamic element matching to reduce noise and ooset, without excessive increase of the charge injection residual ooset. It consists of a chopped transconductance stage and a new cl...

Residual stress analysis was performed on thick, 1–25 lm, depleted uranium (DU) films deposited on an Al substrate by magnetron sputtering. Two distinct characterization techniques were used to measure substrate curvature before and after deposition. Stress evaluation was performed using the Benabdi/Roche equation, which is based on beam theory of a bi-layer material. The residual stress evolut...

A series of heterostructure designs low-voltage InP homothyristors have been investigated using numerical simulation methods. The design with a space charge layer formed in the p-base region n-p-n transistor part was considered as base one. dynamic characteristics and processes that determine rate transition to on state are investigated. It is shown thickness increases from 1 2.6 μm, maximum on...

The battery critical functions such as State-of-Charge (SoC) and State-of-Health (SoH) estimations, over-current, and over-/under-voltage protections mainly depend on current and voltage sensor measurements. Therefore, it is imperative to develop a reliable sensor fault diagnosis scheme to guarantee the battery performance, safety and life. This paper presents a systematic model-based fault dia...

This paper presents a novel transient current differential algorithm for earth fault detection in unearthed (isolated) and compensated neutral medium voltage (MV) networks. The proposed algorithm uses the transient residual currents, which are very sensitive for earth faults detection. The transient values of residual currents are calculated for each feeder in the network and used as an earth f...
