Background: ELECTRICAL injuries are rarely happened but it makes more harmful lesions comparing to other thermal injuries. The aim of this study was to report ELECTRICAL burned patients according to ELECTRICAL VOLTAGE in Shahid Motahari Burn Center.Methods: This Routine data base study was performed on patients with ELECTRICAL burns which were admitted to Shahid Motahari Burn Center from April 2010 to March 2012. Demographic and clinical data had gathered from medical records. Association between VOLTAGE and morbidity or mortality was evaluated used SPSS v. 16.Results: Mean total body surface area of 287 patients (283 (98.60%) male and 4 (1.4%) female) with mean age of 30±0.7 years was 13.56±0.76% (range 1-100). There were 203 patients (70.7%) with low and 84 patients (29.31%) with high VOLTAGE injury. There was significant association between VOLTAGE and place of injury (p=0.001).Conclusion: High VOLTAGE injuries constitute large number of ELECTRICAL injuries which more of these injuries occurred outdoor and in workplace and need more hospitalization. High VOLTAGE injuries are related with more amputation, so people and authorities should pay more attention to such injuries.

A New Static Var Genera tor (SVG), using cascaded full-bridge inverters (FBI) with binary output levels and the parallel connections of two cascaded inverters by means of current sharing reactor in each phases is introduced. The new M-level inverter, where M is 2n+2 - 3, consists of only 2n single-phase full bridges for each phase. The proposed technique not only increases the current capacity of proposed SVG but also decreases the output harmonic contents. Also, it can be connected directly to the distribution system without a transformer. Simulation results, based on the PSCAD/EMTDC, a high performance electromagnetic transient simulation program, are used to illustrate the flexibility of control action and also the performance of the proposed SVG in a power system environment.

This paper presents a simulation of the dynamic VOLTAGE stability in power system. In application of modern power system, dynamic assessment of VOLTAGE stability is known as basic concept. In order to study dynamic VOLTAGE stability in a power system, different dynamic boundaries are defined such as, Hopf bifurcation (HB) boundary. HB point is an oscillatory boundary in power system. For recognition of the bifurcations, it is unavoidable to study the eigenvalues of power system. In spite of this, determination of these eigenvalues needs to dynamic Jacobian matrix of power system and modal analysis that is very time consuming and complex in large systems. Also, different industrial loads (static and dynamic) e.g. induction motors can effect on dynamic VOLTAGE stability boundaries. In this paper, we proposed a solution method based on analyzing the eigenvalues of reduced Jacobian matrix and time domain simulation for assessment of dynamic VOLTAGE stability. In addition, effects of industrial ELECTRICAL loads on the small disturbance VOLTAGE stability are evaluated by the proposed method. To show the effectiveness of the proposed solution method, it is tested on IEEE 14 bus and New England test systems.

Background: Treatment of wounds in diabetes often gets less than perfect healing. One of the reasons for the difficulty in treating wounds in diabetes is the growth of aerobic and anaerobic bacteria. This study aims to determine the pulse VOLTAGE and treatment time that can optimally inactivate bacteria, and their effect on wound healing in mice suffering from diabetes. Methods: The study used ELECTRICAL stimulation with a direct VOLTAGE of 10 volts given a pulse VOLTAGE of 50-80 volts, a width of 50 μ s, and the number of pulses of 65 per second. The research samples were Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) bacteria that grew on beef and mice (Mus musculus) with diabetes. The treatment for S. aureus and P. aeruginosa bacteria was carried out using a pulse VOLTAGE of 50-80 volts for 5-15 min/day and repeated for 3 days. Meanwhile, treatment of mice wounds was carried out with a pulse VOLTAGE of 80 volts for 15 min/day and repeated for 7 days. Results: The results showed that treatment with a pulse VOLTAGE of 50-80 volts and a treatment time of 5-15 min significantly reduced the number of S. aureus and P. aeruginosa bacteria in beef (p 0. 05). Treatment with a pulse VOLTAGE of 80 volts for 15 min made beef free from bacteria. Meanwhile, treatment with a pulse VOLTAGE of 80 volts for 15 min per day for seven days resulted in the wound state of three mice in the maturation phase and two mice in the proliferation phase on day 8 with an average wound area of 0. 108 cm 2. Conclusion: The treatment with a pulse VOLTAGE of 80 volts for 15 min made the beef sterile, the mice wounds healed quickly, and the mice not stressed. The higher the blood glucose level, the slower the wound healing process.
