A 70-year-old woman came to ophthalmology outpatient department with complaints of repeated episodes of itching, redness and watering in both eyes of 3 months duration. She was treated with antibiotics elsewhere but had no improvement. Slit lamp examination showed lice and nits anchored to the eyelashes. Light microscopic examination of the matted eye lashes and crusts further helped in identification of the ectoparasites as Phthirus pubis (Pubic louse or Crab louse) with typical morphology.

The thin layer drying behaviour of tomato slices using a hybrid drying method compared to solar and open sun drying was investigated. The dryer consists of solar collector, photovoltaic solar panel, battery and drying chamber. The dryer was operated as both a solar-energy dryer and as a hybrid solar dryer. The drying performance of the dryer was evaluated with fresh tomato slice and compared with open sun drying under the same climatic conditions. The dryer recorded a raised temperature of 62℃ attainable in the drying chamber of hybrid dryer and 54 o C attainable in the drying chamber of solar dryer. The moisture content of tomato slices was reduced from 94.22 % wet basis to 10 % in 6 hours for hybrid drying method while it took 9 hours to achieve the same moisture content reduction in the solar dryer. The average drying rate and the efficiency was computed as 0.0800kg/h and 71% for hybrid dryer and 0.0578kg/h and 65% for solar-energy dryer respectively. The quality of the tomato samples dried using the hybrid dryer was superior to those of solar and sun drying methods. From the result of this study it shows that a hybrid solar-energy dryer using photovoltaic (PV) solar panel suggested a promising process for adoption to preserve tomato which can prevent it from spoilage and post-harvest losses. The good quality and shelf stable dried tomato slices is indicative for a sustainable productivity that will create a sound avenue for economic growth in tomato producing regions of the world.

The economic development plans implemented since independence have necessarily required increasing amounts of energy. As a result, consumption of energy in all forms has been steadily rising all over the country. This growing consumption of energy has also resulted in the country becoming increasingly dependent on fossil fuels such as coal, oil and gas. Rising prices of oil, gas and coal and potential shortages in future lead to concerns about the security of energy supply needed to sustain our economic growth. Increased uses of fossil fuels have also caused environmental problems both locally and globally. Against this background, the country urgently needs to develop a sustainable path of energy development.India is gifted with rich natural and renewable resources of energy like solar, wind and biomass. India has ranked the second position for the renewable energy attractiveness index in the world. According to the statement, India continued its upward trend in the index to second position with the government's programme to build 175 GW in renewable energy generation by 2022 and to have renewable energy account for 40 per cent of installed capacity by 2040. The country has added more than 10 GW of solar in the last three years from 2.6 GW in 2014. It may be necessary to continue with subsidies in the case of socially oriented programmes to Abstract: Growing consumption of energy has also resulted in the country becoming increasingly dependent on fossil fuels such as coal, oil and gas. Rising prices of oil, gas and coal and potential shortages in future lead to concerns about the security of energy supply needed to sustain our economic growth. Photovoltaic converts solar energy in to electricity that can be used for myriad purposes such as lighting, pumping and generation of electricity. This study focused determinants factors for adopting solar energy in the selected villages in the study area. Based on the comprehensive energy survey 300 households in Villuppuram district, researchers present the structure of rural household solar energy consumption in the study area. The study has been conducted with pre-structured interview schedule. Present study elaborated the benefits and difficulties faced by the respondents for using solar energy in Villuppuram district.
