Optimal Location Of Series-Shunt Facts Devices In Transmission Line And Impact Of SSSC Compensated On Performance Of Distance Relay

The research works says that the impacts of facts devices changes with the change of their location on transmission line. Basically in power system we have two types of compensation devices. First is series facts devices, second is shunt facts devices by using these devices controlling of transmission line voltage and power flow is possible. Facts devices are also very useful to control the reactance power of transmission line and damping of power system oscillation for high power is possible. Series facts devices are connected in series of transmission line and works as a controllable voltage source. Shunt facts devices are connected in shunt with power system line.it works as a controllable current source. During the SLG fault, shunt capacitance of SSSC-compensated line affects the performance of distance relay. Research also shows the impact of ignoring the shunt capacitance of the line on the distance relay over and under reach conditions. By using MATLAB we can study the effects of series and shunt compensation according to the variation of location of these in transmission line. We can find the most suitable and optimal location of series, shunt or the combination of both compensation

Application of Soft Tissue Laser in the Management of Recurrent Apthous Stomatitis: A Placebo Controlled Study

Apthous ulcers are relatively common pathology and are very painful, so in order to facilitate the relief in pain and healing of these ulcers application of LLT has been done in the present study.  The purpose of this study was to assess the efficacy of Low Level Laser Therapy in the treatment of recurrent aphthous ulcers. 30 patients of both sexes and all age groups with two recurrent aphthous ulcers were included in the study. One ulcer in each subject was subjected to Low Level Laser Therapy as study group and one ulcer in each subject was considered for the Sham Control group. The Student's t-test was used for statistical evaluation of the data. The study group (LLLT) showed a statistically significant reduction in pain as compared to the sham controlled group.  Complete resolution of the ulcers in the study group was observed to be 4.7 ± 1.2 days and control group was 8.4 ± 2.6 days. On comparison with the sham group, the complete healing time for the study group (LLLT) was found to be highly significant, with a p value of <0.001

Characterisation and antimicrobial resistance of sepsis pathogens in neonates born in tertiary care centres in Delhi, India: A cohort study

Background: Sepsis is one of the most common causes of neonatal deaths globally. Most sepsis-related deaths occur in low-income and middle-income countries, where the epidemiology of neonatal sepsis remains poorly understood. Most of these countries lack proper surveillance networks, hampering accurate assessment of the burden of sepsis, implementation of preventive measures, and investment in research. We report results of neonates born in hospital from a multicentre collaboration on neonatal sepsis. Methods: In this cohort study, dedicated research teams prospectively followed up neonates born in one of three tertiary care centres in Delhi, India (Vardhaman Mahavir Medical College, Maulana Azad Medical College, and All India Institute of Medical Sciences [coordinating centre]) and subsequently admitted to the intensive care unit. Neonates were followed up daily until discharge or death. On clinical suspicion, neonates underwent sepsis work-up including blood cultures. The isolated organisms were identified and tested for antimicrobial susceptibility. We defined Gram-negative isolates resistant to any three of five antibiotic classes (extended-spectrum cephalosporins, carbapenems, aminoglycosides, fluoroquinolones, and piperacillin-tazobactam) as multidrug resistant. Findings: 13 530 neonates of 88 636 livebirths were enrolled between July 18, 2011, and Feb 28, 2014. The incidence of total sepsis was 14·3% (95% CI 13·8–14·9) and of culture-positive sepsis was 6·2% (5·8–6·6). Nearly two-thirds of total episodes occurred at or before 72 h of life (defined as early onset; 1351 [83%] of 1980). Two-thirds (645 [64%]) of 1005 isolates were Gram-negative including, Acinetobacter spp (22%), Klebsiella spp (17%), and Escherichia coli (14%). The pathogen mix in early-onset sepsis did not differ from that of late-onset sepsis (ie, after 72 h). High rates of multidrug resistance were observed in Acinetobacter spp (181/222, 82%), Klebsiella spp (91/169, 54%), and Escherichia coli (52/137, 38%) isolates. Meticillin resistance prevailed in 61% (85/140) of coagulase-negative staphylococci and 38% (43/114) of Staphylococcus aureus isolates. Nearly a quarter of the deaths were attributable to sepsis. The population-attributable risks of mortality were 8·6% in culture-negative sepsis, 15·7% in culture-positive sepsis by multidrug-resistant organisms, and 12·0% in culture-positive sepsis by non-multidrug-resistant organisms. Interpretation: The high incidence of sepsis and alarming degree of antimicrobial resistance among pathogens in neonates born in tertiary hospitals underscore the need to understand the pathogenesis of early-onset sepsis and to devise measures to prevent it in low-income and middle-income countries.
