ABSTRACT- Background: Malnutrition constitutes a major public health concern worldwide and serves as an indicator
of hospitalized patient’s prognosis. Nutritional support is an essential aspect of the clinical management of children
admitted to hospital. Malnutrition has been long associated with poor quality, poor diet and inadequate access to health
care, and it remains a key global health issue that both stems from and contributes to weakness, with 50% of childhood
deaths due to principal under nutrition.
Methods: The present hospital based cross sectional study was conducted in April to Dec 2015 among 300 rural
adolescents of 9-18 years age (146 boys and 154 girls) attending the outpatient department at Patna Medical College and
Hospital, Bihar, India, belonging to the all caste communities. The nutritional status was assessed in terms of under
nutrition (weight-for-age below 3rd percentile), stunting (Height-for-age below 3rd percentile) and thinness (BMI-for-age
below 5th percentile). Diseases were accepted as such as diagnosed by pediatrician, skin specialist and medical officer.
Results: The prevalence of underweight, stunting and thinness were found to be 31%, 22.3% and 30.7% respectively. The
maximum prevalence of malnutrition was observed among early adolescents (23% - 54%) and the most common
morbidities were diarrhoea (16.7%), carbuncle / furuncle (16.7%) and scabies (12%).
Conclusion: Malnutrition among hospitalized under five children and around suffers moderately high rates of
malnutrition. Present nutrition programs attention on education for at risk children and referral to regional hospitals for
malnourished children. Screening tools to classify children at risk of developing malnutrition might be helpful.

A New approach for controlling the power flow in a transmission system using ...IJMER
Electrical power systems is a large interconnected network that requires a careful design to maintain the system with continuous power flow operation without any limitation. Flexible Alternating Current Transmission System (FACTS) is an application of a power electronics device to control the power flow and to improve the system stability of a power system. Unified Power Flow Controller (UPFC) is a new concept for the compensation and effective power flow control in a transmission system.Through common DC link, any inverters within the UPFC is able to transfer real power to any other and there by facilitate real power transfer among the line. In this paper a test system is simulated in MATLAB/SIMULINK and the results of the network with and without UPFC are compared and when the voltage sag is compensated, reactive power is controlled and transmission line efficiency is improved.

A High-Performance SPWM Controller for Three-Phase UPS Systems Operating Unde...ijiert bestjournal
The increased use of rectifiers in critical loads employed by the information technologies,and medical and military equipment mandate the design of uninterruptible power supplies (UPS) with high- quality outputs. The highly nonlinear currents drawn especially by high-power single-phase rectifier loads greatly distort the uninterruptible power supplies (UPS) outputs. The distorted uninterruptible power supplies (UPS) voltages cause generation of low dc voltage at the output of the rectifier loads,which causes high current flow,increased power losses,and possibly the malfunction of the critical load or the uninterruptible power supplies (UPS). As a result,different harmonics mitigating techniques have gained a lot of attention. The main objective of this project is to develop simulation of a high-performance Pulse Width Modulation (PWM) technique based AC-DC converter system operating under highly nonlinear loads using MATLAB/SIMULINK. Here,controlled Insulated-gate bipolar transistor (IGBT) based AC-DC converter is used to supply the load instead of Diode or Thyristor Bridge. The pulse width modulation method is quite effective in controlling the root mean square (RMS) magnitude of the AC-DC converter output voltages and shape of input current. This enables automatic harmonic compensation by Rectifier itself.
