High voltage DC Transmission has been alternatively used for large amount of bulk power point to point transmission over long distance. Recent advancement in converter technology has further increased the power carrying capacity of transmission even more. Most of these projects uses Earth electrode as a return path, during the operation DC ground potential rises which sometime has adverse effects...
A pure and ZnO added CdO thin films are prepared by chemical bath deposition to study their ethanol sensing properties. The depositions were carried out in a highly alkaline condition where in cadmium acetate was used as a source of cadmium while zinc acetate was added as the source of Zn inclusion. These films were subsequently annealed at 723K and studied for its morphological, optical and gas sensing...
The management of medical equipment is acknowledged to be many-faceted. Maintenance is one aspect, but the field often focusses on resourcing technical staff for the purpose. We present here a new course for user (or `first-line') maintenance of medical equipment. It is hoped that the course material can be adapted for use in settings other than the original Indian environment.
There are various ways to get an estimate of the mud slowness. The most common one consists in performing acoustic measurement at the surface using mud sample or using empirical laws linking mud slowness as a function of mud density and type. In this case, the estimation of mud slowness is said to be indirect as the estimated mud value is not the one measured in the well at the time the tool recorded...
