The fungal metabolite, brefeldin A (BFA), is known to inhibit guanine nucleotide exchange on the ADP-ribosylating factors that are involved in vesicle membrane trafficking. Here, we investigated the action of BFA on Ca2+-regulated exocytosis in single rat adrenal chromaffin cells. Incubation of chromaffin cells with BFA (1 or 10 microM) for 2 h effectively disrupted the Golgi membranes but did ...
This new LCR Meter is especially designed for measurements of low-value components in integrated circuits and thinJilm hybrid circuits, as wellas of discrete components. /t uses a four-pair measurement technique to reduce errors caused by stray capacitance, residual inductance, and mutual inductance of the tesf /eads. T N THE MANUFACTURE of integrated circuits, I good process control is essenti...
In the oil industry, huge saving may be made if suitable multi-interface level measurement systems are employed for effectively monitoring crude oil separators and efficient control of their operation. A number of techniques, e.g. externally mounted displacers, differential pressure transmitters and capacitance rod devices, have been developed to measure the separation process with gas, oil, wa...
Abstract: This paper proposed three-dimensional numerical simulation method by coupling of electrostatic and fluid fields to evaluating the performance of electrical sensor in the concentration measurement of gas/solid two-phase flow. Compared with the static numerical simulation, this real-time dynamic 3-D simulation method can research on a designed capacitance sensor combining the dynamic ch...
The two-phase flow widely exists in the nature and industrial processes. The measurement of two-phase flows, including gas/solids, gas/liquid and liquid/liquid flows, is still challenging. Fusions of electrical tomography with conventional sensors provide possibilities to improve two-phase flow accurate measurement. In this paper, fusions of (1) electrical resistance tomography (ERT) with elect...
This paper reports a comparative study between yarn mass and yarn diameter measurement systems using a differential capacitance tester and an optical coherent signal processing diameter tester respectively. A full description of the systems is presented along with their new contributions, namely 1mm length samples analysis for a capacitive tester and optical signal processing to eliminate the i...
