Review Paper on Solid Waste Management in India
Abstract: Solid waste management is a major problem in urban areas of India. It is due to large urbanization, industrialization, and increasing population. The solid waste management systems ranked very poorly in India over the last few decades. Approximately 90% of residual waste is dumped instead of its proper landfilling. The solid waste management system should be improved in India because it will be beneficial for our future generations and the …

Review on Azomethine-Compounds with Their Applications
Abstract: Azomethine derivatives are very important and the initiating compound for most synthetic chemistrycompounds in all their fields. Since R, R1 is an alkyl or aryl group, the first to prepare and isolate itwas the German scientist Hugo Schiff in 1864 from the condensation of the carbonyl group (aldehyde,ketone) with a primary amine compound (aliphatic, aromatic). During the past few decades there hasbeen great interest in Schiff base compounds. The rules …
