Introduction: Welding is considered to be one of the main sources of occupational exposure to non ionizing radiations. The present study was conducted to examine the rate of occupational exposure to non-ionizing radiation in common welding processes. Materials and Methods: In the present descriptive analytical study, occupational exposure to different types of non-ionizing radiations in...
According to the standard content, it provides a completely satisfy permeable brick coefficient test detection device. This for improvement of device, vacuum control system, electric system and weighing tank organic union, more in line with operation process. It has strong durable, easy maintenance, advantages small human error influence, systematic device automatic control, single convenient o...
introduction: public and occupational exposure to extremely low frequency (elf) electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. the purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological ef...
Micro-grids have become the building block of modern energy systems, where distributed resources are characterizing feature. The charging operation electric vehicles can be exploited as a flexible load to achieve operational goals micro-grid. In particular case car-sharing fleets, degrees freedom in procedures reduced when compared private users. this work, we illustrate how car sharing fleet i...
Advances in new information technology and the drastic growth of the Internet over the past decade have considerably changed the end-user computing environment. Therefore, it is appropriate to review the measures of user satisfaction with information systems technology, especially in a web-based environment, which accounts for a major component of the end-user computing environment. The objecti...
We developed a telemedicine instrument for home monitoring of subjects with respiratory diseases. The instrument directly measures blood oxygen saturation and pulse rate, but the most relevant aspect is that it also acts as digital recorder of parameters coming from several external instruments (spirometer, capnometer, NIBP device, etc.). It also connects to all pulmonary ventilators. The instr...
In this paper, we present an initial effort in the creation of a generic instrument for measuring the performance of collaboration across organisational and professional boundaries. Based on the literature and previous research on collaboration, a three-dimensional instrument for measuring the preconditions for and the performance of collaboration has been constructed. Validity and reliability ...
With the increasing attention on managerial coaching as an effective leadership initiative in organizations, there have been increasing needs for reliable and valid tools to assess managers’ coaching skills. This study reviewed and revised an existing instrument measuring coaching skills in organizations created by McLean, Yang, Kuo, Tolbert, and Larkin (2005). Through qualitative and quantitat...
A non-contact and low-cost nanomaterial based fiber-optic sensor is developed for measuring large values of electric currents. The magnetic field, generated by the electric current, changes the refractive index of a liquid in which nanomaterial particles are suspended. The change of refractive index is converted to a change in the intensity of light transmitted in an evanescent field based fibe...
