#Deforestation, #Landslide, #HillAreas #ijsrd
Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Deforestation includes conversion of forestland to farms, ranches, or urban use. Since the industrial age, about half of world’s original forests have been destroyed and millions of animals and living things have been endangered. Despite the improvements in education, information and general awareness of the importance of forests, deforestation has not reduced much, and there are still many more communities and individuals who still destroy forest lands for personal gains. Deforestation also provides stability to slope through which mass movement of rocks, debris could not occur. As the plant or tree roots provides some reinforcement and also remove groundwater. On hilly areas vegetation can stabilize steep slopes and if the cutting of trees continues it would result in a drastic change in the atmosphere or in the environment. In this paper there is summarization of cause of deforestation, deforestation causes, environment changes i.e. loss of biodiversity and how deforestation is related to landslide.

A Review Paper on Effects of Different Intake #Manifold #Designs on #Diesel #Engine #Performance and #Emissions
#Combustion, #compressionRatio, #InletManifold, #Swirl
One of the objectives of car manufacturers is to improve engine performance, reduce consumption and reduce emissions. To achieve this objective, it is important to understand the phenomena involved in the combustion chambers of engines. There are various factors that influence the engine performance such as compression ratio, atomization of fuel, fuel injection pressure, and quality of fuel, combustion rate, air fuel ratio, intake temperature and pressure and also based on piston design, inlet manifold, and combustion chamber designs etc. Geometrical design of intake manifold is one such method for the better performance of an I.C. Engine. Air swirl motion in CI engine influences the atomization and distribution of fuel injected in the combustion chamber. Intake manifolds provides Air motion to the chamber. So, to get the maximum output with the least input on Diesel engine researchers are experimentally and computationally working on construction of the intake manifold configurations for increase in engine performance and reduction of Exhaust Emissions. In this paper i have studied few papers and also gone through basics of my topic from various books to understand the phenomena.
