Objective: To assess the knowledge and practice of warm-up among athletes and, find out the relationship between warm-up and injury prevalence. Warm-up is a widely accepted practice and is universally performed as efficient tool to improve physical performance in sports and athletic events. Young athletes often do not warm-up adequately and run the risk of injury. This could be attributed to a low level of knowledge about the importance of warm-up. Adequate knowledge of the potential benefits of warm-up and a positive attitude towards it can aid the minimization of sports related injuries and encourage student athletes to adopt structured programs that would improve performance.Methods: A cross sectional survey included 250 athletes from non-medical colleges within the age group 15 to 25 years who had participated in athletics and sports at different levels of competition. Participants completed a questionnaire, the data of which were analyzed.
Results: Study findings showed that most of the athletes (68.4%) showed moderate knowledge of warm-up while majority (71.2%) exhibited excellent practice of warm-up. Injury prevalence reported as 71.2% among the participants. There was no correlation between knowledge and injury prevalence (χ²=5.03, p=0.388, NS) as well as level of practice and injury prevalence (χ²=6.43, p=0.109, NS).
Conclusions: While adequate knowledge and practice of warm-up may not lessen the incidence of injury, further investigation into the practice of warm-up specific to activity is required to draw more comprehensive conclusions.

Pain continues to be a prevalent symptom experienced by cancer patients. Guided Imagery (GI), a cognitive behavioural pain management strategy, involves the use of one's imagination which may modulate pain by distraction and improve the sense of wellbeing. This study aimed at finding out the effectiveness of GI on intensity of pain and Quality of Life (QoL) of patients with cancer. An evaluatory approach with one group pre-test post-test pre-experimental design used for the study. Thirty cancer patients aged between 20-70 years with pain ?2 on Visual Analogue Scale (VAS) were selected using purposive sampling technique. GI was administered after the assessment of preintervention intensity of pain and QoL by using VAS, and Functional Assessment of Cancer Therapy - General (Modified) Scale (FACT-G) respectively. Intensity of pain was measured before and after intervention twice a day for 5 days and post-intervention QoL was assessed on fifth day evening after the intervention using the same tool. The mean post-intervention intensity of pain score was lower than mean pre-intervention intensity of pain score over a period of 5 days (p<0.05), both in the morning and evening. The mean post-intervention QoL score was higher than the mean preintervention QoL score (p<0.05). GI is an effective strategy in reducing the intensity of pain and improving the QoL of cancer patients. GI may be easily integrated into bedside nursing as well as in various clinical settings. GI is a low-cost method in relieving psychological and physiological distress.Keywords

This project presents efficient “Full Bridge High Frequency Series Resonant Inverter for Induction Heating application”. In general, the induction-heating technique requires high-frequency current that is capable of inducing high-frequency eddy current in the work piece that results in heating. In this project series resonant inverter featuring soft switch on transitions is used. A cost-effective active snubber circuit is used to optimize the switch off transition. Active snubber uses active components. This allows the converter to operate under a wide range of operating conditions. The series resonant inverter consists of resonant circuit and it delivers maximum power to the load at resonant frequency. The inverter system is designed and the simulation is done using Matlab.Full Text

This paper presents the modeling of single phase, three phase rectifiers and suitable controller design for the modeled rectifier circuit the primary application of rectifiers is to derive DC power from an AC supply. Virtually all electronic devices require DC, so rectifiers are used inside the power supplies of all electronic equipment. PWM rectifier is now becoming popular due to its low distortion input current, unity power factor operation, bi-directional power flow ability and can offer excellent dynamic response of the dc output voltage. A three-phase PWM rectifier used together with closed-loop dc–dc converters for converting DC power from one voltage to another is much more complicated. In order to perform the above operation rectifier switches should be controlled properly. Hence it is much needed to design a suitable controller for single phase and three phase rectifier. From the small signal transfer function model, the controller scan be designed and the simulated results are presented.Keywords

The Matrix Converter (MC) chosen in this work is capable of providing a variable three phase output voltage from a fixed single phase input using single stage phase conversion principle. This MC effectively provides three phase power to three phase variable speed drives. The implementation of MC requires solid state bidirectional switches. A new pulse generation scheme is developed to produce three phase voltage at the output. The performance of the Matrix Converter is evaluated using MATLAB/SIMULINK for different frequencies. Simulation results for three phase resistive and inductive loads are presented. The simulation results validate the developed conversion strategy.Keywords

Advances in Wireless Sensor Communication Network (WSCN) technology has provided the availability of small and low-cost sensor nodes with capability of sensing various types of physical and environmental conditions, data processing, and wireless communication. Variety of sensing capabilities results in profusion of application areas. However, the characteristics of wireless sensor networks require more effective methods for data forwarding and processing. In WSCN, the sensor nodes have a limited transmission range, and their processing and storage capabilities as well as their energy resources are also limited. Routing protocols for wireless sensor networks are responsible for maintaining the routes in the network and have to ensure reliable multi-hop communication under these conditions. In this paper, we give a survey of Qos Based routing protocols for Wireless Sensor Network and compare their strengths and limitations.
