A roof is uppermost part of building or shelter which plays a predominant role in protecting inner elements and living things inside structure, this protects against weather, rain, snow, heat, wind and sunlight. The protection properties of roof vary by composites with which the roof is made. In this paper analysis of temperature, humidity and illuminance properties variation due to different types of roofs, the survey made on different roofs such as R.C.C, Asbestos sheets, planks and shack type of roofs for 24 hours are compared to reading that are obtained by open place reading without any roof. This survey clearly represented that readings gradually increases when sun is at his highest point and reduces to zero in the absence of sun. This survey also revealed that using asbestos sheet roof will increases humidity of roof eventually and by using shank roof reduces the temperature, humidity, and lux values passing in to building. Hence this says that although shank roof are less strength roof compared to all roofs these can be used in arid region to reduce interior temperature and humidity, although asbestos sheets are thin layered these can be used in places where humidity and temperature is required compared to temperature and humidity outside the building.

A study was carried out to find out the water quality ofByramangala lake of Ramanagara district. The water quality of Byramangala lake water and ground water from bore wells situated in the area within 600 meters surrounding the lake was analyzed. The quality analysis of various parameters such as BODs, COD, DO, E-Coli, and pH, Total Dissolved Solids, Total Suspended Solids and Total Hardness were tested. In addition, the presence of metals such as Cadmium (Cd), Chromium (Cr), Lead (Pb), and Iron (Fe) in the lake water and ground water samples were tested. Results for the various tests conducted showed similar trends for both lake water and ground water. It was observed that certain parameters such as BOD5, and COD were beyond permissible limits as per the BIS standards for drinking water. A few remedial measures have been proposed that may help in mitigating the pollution in the selected project area Byramangala Lake.

Tuberculosis (TB) is one of the major global health problem which affects millions of people each year. For the routine diagnosis of TB, microscopic technique is used but it has lower sensitivity and specificity. This study was carried out to evaluate the efficacy of loop mediated isothermal amplification (LAMP) over smear microscopy to detect Mycobacterium tuberculosis. Out of 84 processed samples processed in this study, the diagnostic tests showed varying results. Using smear microscopy, 16(19.05%) and with the LAMP assay, 17(20.24%) cases were found positive for M. tuberculosis. The sensitivity of the LAMP assay (87.5%) was greater than that of microscopy (82.35%) while the specificity of both methods was comparable (>95%). Being more sensitive than microscopy, LAMP assay is more likely to show the positive result and solve the errors in diagnosis of the TB cases. Thus, LAMP assay can be an important and cost-effective tool for appropriate and timely diagnosis of TB patients. This can further assist to implement intervention programs against TB.
