The energy that is used today comes from fossil fuels‚ which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar‚ hydroelectric‚ geothermal and wind energies can be used‚ to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses.

IMPACT OF LARGE DAMS & RIVER VALLEY PROJECTS ON SOCIETY AND ENVIRONMENT Case Study : Narmada Valley project Kamal Gupta This paper tries to bring forth the various aspects of the impact made by large river valley projects on the environment and society of the concerned areas and of the nation as a whole. We start by asking why we need large dams and river valley projects. Then we talk briefly about the development model followed by India post-independence where we

located in Indira Gandhi Wildlife Sanctuary in Coimbatore district‚Tamil Nadu‚ India. The 9.31 km²‚ 33.53 m deep[1] Amaravathi Reservoir was created by this steep dam. It was built primarily for irrigation and flood control and now also has 4 megawatts of electric generating capacity installed. It is notable for the significant population of Mugger Crocodiles living in its reservoir and catchment basin. The Kateri (Katery) hydro electric power station is located in Nilgiris‚ Tamil Nadu‚ India. It is a

forces somewhere remote from where it is practical to locate large machinery. Hydraulics gives high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere. That eliminates return piping and leakage problems. b) Advantages: It uses ’incompressible’ fluid which results in a greater‚ more efficient & consistent work or power output. This is due to the fact that hydraulic

2.2 Aetiological agent: Classification and characterisation The monkeypox virus is a member of the genus orthopox (family Poxviridae). Other members include cowpox‚ vaccinia‚ and variola (smallpox) viruses. Poxviruses are the largest vertebrate viruses known. The virions contain a linear double-stranded deoxyribonucleic acid (DNA) genome and enzymes that synthesise messenger ribonucleic acid (RNA). The viruses multiply in the cytoplasm of the host cells. The poxvirus family consists

Mechanical. 6. List the main components of an aircraft hydraulic system and describe briefly their functions. a. Control valve - To direct the flow of the flow fluid from pump to operate jack and permit fluid from return side of jack to return to reservoir or header tank. b. Relief valve - To prevent damage though excessive pressure. c. One-Way Restrictor. - Reduces the flow of fluid in one direction only‚ thereby slowing the movement of the component being operated. d. Non-Return Valve (NRV)

Sustainability is the ability of a population to thrive socially and economically but without over using resources and damaging the environment for the future generations. This requires large amounts of planning and management of resources across the globe. Curitiba in southern Brazil has the 5th biggest economy of cities in Brazil. The city acts as one of Brazil’s financial hubs. Nevertheless Curitiba also has a strong manufacturing pedigree with the South American headquarters of Volvo trucks

Why should tropical rain forests be conserved? Tropical rainforests are thought to posses more plants and animals than any other forests on earth. Most tropical rainforests are located around and near the equator‚ they have existed on earth for hundreds of millions of years. But they are among the most endangered ecosystems globally due to humans. They are an important part of human life and are know as the “lungs of the planet” they have many animals‚ and many natural medicines come from tropical
