A study on the effect of sisal fibre and waste plastic strips tropical black clay (also called Black cotton soil, BCS) was carried out. Tests piloted natural treated soil consist California bearing ratio (CBR), Atterberg limits compaction for different percentages inclusion (0, 0.5, 1, 1.5 2%) by dry weight soil. Results obtained showed that liquid limit BCS initially fluctuated between 43.4% 5...

Farmers in India rarely employ plastic mulches tomato cultivation, despite the fact that it has potential to save irrigation water, manage weeds, and increase output. The precision of water for production using various colour was evaluated an experimental farm at UAS-Raichur. Because effect levels, 120 percent evapotranspiration based treatment had most soil moisture availability, while 60 by d...

BACKGROUND There is increasing recognition of the importance of early environmental exposures in the development of childhood asthma. Outdoor air pollution is a recognized asthma trigger, but it is unclear whether exposure influences incident disease. We investigated the effect of exposure to ambient air pollution in utero and during the first year of life on risk of subsequent asthma diagnosis...

Gradual increase of the Earth's surface temperature can cause many significant changes on the climate of our planet. This problem is progressively increasing. One of the main reasons for this phenomenon is the absorption of the Sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. In this descriptive and cross-sectio...
