Biochemical mechanism for generating photosynthesis and rapid reproduction of Chlorella cells, using solar energy
Abstract: The main source of oxygen release and utilization of atmospheric carbon dioxide, using solar energy by phytoplankton cells of the world ocean, is the photosynthetic nanostructure of phytoplankton cells— chlorophyll. During the process of photosynthesis, the Chlorella cell not only releases oxygen and utilizes carbon dioxide from the atmosphere, using solar energy by the Chlorella cells of the world's oceans, but also produces glucose inside the cell, which, in the …

Wireless Sensor Network Based Road Traffic Monitoring in Hilly Terrains
Abstract: AbstractIn the hilly terrains tree falling is a natural phenomenon, also river/canals overflowing in rainy season always disturb the free movement of traffic. Eventually there will be narrow roads in the hilly terrains. Traffic block occurs due this reason can be easily occurred. These incidents block the roads for several hours. Authorities are always informed much later and precious hours are spent on the roads by public. To avoid this, …

Use of Simple Scientific Principles in Rural Areas for Common Utility
Abstract: Archimedes principle describes the laws of a floating body, be it a country boat or an ocean going ship. Based on such principle and common laws of forces defined by Newton’s laws for motion, the stability equations of a floating body has been developed. Some of the Indian villages, mostly in northern India, are inundated with many rivers and canals which are mostly used for economic activities like fishing, irrigation …

Monitoring of Tehri Hydroelectric Plant Induced Land Use Land Cover Change Detection in Garhwal District of Uttarakhand
Abstract: The present study analyses the land use change caused by the construction of Tehri dam in Bhagirathi river. Geospatial techniques like Geographic Information System (GIS) and remote sensing have been used to make land use map using Landsat satellite image of 2000 and 2014. In Tehri district, change in land use and new developments (industrial, urban and commercial) were observed. Land use land cover change was done using two satellite …

Review of Construction's Impacts on Marine Areas
Abstract: In order to manage flooding, generate electricity, facilitate shipping, support agriculture, and advance industry, dams have greatly benefited human society. The development of dams, however, seems to have a significant impact on neighbouring coastal areas and the natural ecosystems downstream. This review utilises contemporary studies to thoroughly examine how dam construction has impacted river hydrology, geomorphology, and ecology of lower stream reaches globally in order to synthesise these impacts. The …
