Increase in need of non-renewable energy sources has directed to the installation of PV plants in many areas. But considering the availability of land and the charges, the PV plant can be installed on water bodies like dams, reservoirs, lake, waste water treatment plants, canals etc. Floating type PV panels has a number of advantages compared to the land-based PV plant; its efficiency can be increased by effective cooling and tracking mechanism. The installation in water bodies offers additional advantages to the aquatic environment like reducing the evaporation rate of the water body, reduces unwanted plant growth in water body; improving the water quality. In this paper, detailed description of floating and the rotating structures in the plant. For higher efficiency the solar panel should be tracking in two axes, that is, tracking of azimuthal and altitude axis. Hence, dual axis tracking system is adopted and the mechanism is explained. Torque calculations are made for selection of correct stepper motor and hybrid linear actuator. Different materials for the platform are compared. A prototype made of wood was design and developed in NIT Puducherry.

Background: The burden of non-communicable diseases such as diabetes and coronary heart disease is increasing both globally and in India. The present study was conducted to estimate the prevalence of risk factors associated with non-communicable disease and to study the association of the risk factors with non-communicable disease among tribal population of Lefunga Block of Tripura.Methods: A cross-sectional study was conducted in Lefunga block during April to June 2017 among 150 Indigenous tribal population of Tripura. Multistage random sampling was used. A predesigned, pretested, semi-structured modified WHO STEPs questionnaire was used. Chi square and Multiple Logistic Regression was done to see association.Results: Mean age was 39.03±12.76 years. Majority (66.7%) were females and (44.7%) had studied up to secondary. (26%) were tobacco smokers and (68%) were tobacco chewing. (36%) were alcoholic. (89.3%) had exercising for <2.5 hrs. 68% were taking vegetables >10 times/ week and 88.7% were taking fruits <5 times/week. (26%) were overweight, (45.3%) had abdominal obesity and 31% were hypertensive. 93.3% were aware of the harmful effects of tobacco consumption. Multiple logistic regression analysis showing factors associated with male were more likely to had higher abdominal obesity and alcohol user >50 yrs, government employee. With smoking, male having more chances of smoking and Age group of 20-30 yrs and 31-40 yrs.Conclusions: The mean age was 39.03±12.76 years. (26%) were overweight, (45.3%) had abdominal obesity and (31%) were hypertensive. NCD clinic, IEC should be increased.

Background: Breastfeeding is the best preventive intervention and has potential impact on child morbidity and mortality. In spite of these demonstrated benefit of breastfeeding, the duration and prevalence are still low in first six months of life. The objectives of the study were to estimate the prevalence of the practices of breast feeding among those mother who have children < 2 years of age and to study the significance of association of risk factors with breast feeding among mothers of rural health training centre of JNUIMSRC, Jaipur. Methods: A cross sectional study was conducted in field practice areas of rural health training centre, JNUIMSRC, Jaipur. 204 mothers having children between 0-2 years age group were included by Purposive sampling method. Pretested Predesigned questionnaire was used to collect data. Results: Majority of the mothers were in age group of 18-22 years, Iliterate mothers were 20.6%, Primary level of education 57.4%. Awareness regarding exclusive breastfeeding was more among literates than illiterates (p<0.05). Pre lacteal feeds were practiced among 30.9% of mothers before initiation of breast feeding. Conclusions. Exclusive breastfeeding upto 0-6 months was practiced by 26.9% of mothers.
