Abstract: The main aim of this review paper is to give detail study about the gearless power transmission mechanism at right angle (900) with the help of L-shape rod (EL-BO ROD) of uniform diameter, Dimension (Identical rod). The mechanism is very important defining application in replacement of gear. It is mainly based on the theoretical, analytical and Finite Element Method (or FEA). Figuring of various parameters such as number of pins, material, dimension difference of component, speed and torque. Gearless power transmission for skew shafts minimize the losses, costs and save the time and space. This system countenance the changing in the orientation of shaft during motion which is very interesting and bewitching about this mechanism. Odd pins or links like 3, 5, 7, 9…must be used in this system and each links are fixed in the drilled hole at both ends of the shafts due to which motion is transferred. Functionally the system is very smooth and work effectively with a very minimum amount of power losses.

Abstract: Municipal Solid Waste Management or MSWM is the burning issue in India as well as other developed countries. There are various challenges in MSWM in urban India which is the motivation of the present study. Due to the urbanization municipal solid waste (MSW) generation is enhanced and instinctive handling of MSW degrades the urban environment and causes health hazards. In this paper, an attempt is made to depict the major problems of MSWM, in addition to a comprehensive review of MSW generation, its characterization, collection, and treatment options as practiced in India. The current practice of MSWM in Indian states and important cities of India is also reported. Keywords: Urbanization; Municipal Solid Waste; biodegradable; recycling Download PDF
