The present study evaluates the Anti-larvacidal of methanolic extract of Cassia occidentalis leaf, Bamboosa Vulgaris and Mukundus Saprossi at various concentrations against malarial vector. The various plant extracts exhibited larvacidal activity at different time intervals (24 hrs and 48 hrs). The mosquito larva of LC 50 and LC 90 values of Cassia occidentalis for I instar larvae 60.69%, 119.74%, the II instar 64.76%, 121.60%, III instar 67.78%, 123.35%, IV instar 70.56%, 122.81% and pupa 92.21%, 162.52% respectively.Keywords
Cassia occidentalis, Bambusa valgaris, Sapindus mukurossi, Anti-Larvacidal, Dechlorinated Water.

Mahatma Gandhi National Rural Employment Guarantee Scheme (MNGREGS) is playing a vital role for rural people and helps to boost up the involvement of women in society and economy. There is inequality and vulnerability of women in all spheres of life. They need to be empowered in all walks of life. Without the active participation of women, establishment of a new social order may not be successful, because women constitute half of the population. It firmly states that the status of women would not change merely by bringing legislations;it must be supported by change in the women's social circumstances and situations and also in men's existing attitude towards women. The present paper studies the women's participation through MGNREGS in Andhra Pradesh and also the issues and challenges related to women participation in MGNREGS.Keywords

Capacitor banks are installed in an increasing number to control power quality issues and improving the power factor to counteract the reactive power in the transmission and distribution networks. Due to load fluctuations switching of capacitor banks is a typical phenomenon. Capacitor bank is normally having concentrated capacitance in contrast with distributed capacitance. It generally draws more current than unloaded cableor line in practical cases up to several hundred amperes. Hence, switching of capacitor bank causes a very high rate of rise of transient recovery voltage across circuit breaker contacts. This scenario can be simulated in testing laboratories by a voltage source connected to a circuit breaker which again is connected to a large capacitance in terms of IEC called capacitive current switching test. Non-sustained disruptive discharge (NSDD) is a voltage breakdown after the vacuum circuit-breaker open the fault current which will not cause the recovery of power frequency current. Restrike is different from NSDD, the recovery of power frequency current between the contacts will make the breaker failed. It’s not easy to show the distinction between NSDD and restrike during some type tests. The paper presents the study of performance evaluation of the circuit breaker during the capacitor current switching duties. A statistical analysis of failure of circuit breaker during capacitor current switching tests are included in the paper to help the manufacturers & utilities, so that the care can be taken for trouble free services. The paper also discusses the changes made in the IEC 62271 – 100, Amendment1:2012 for conducting the capacitive current switching tests.Keywords
