Ratna variety of mango had maximum large size fruits. Due to the overall appearance, colour and sugar acid blend of Ratna variety, it may get high price in international market. Harvesting with proper maturity (specific gravity more than 1.00) affects post harvest life of fruit. CFB boxes followed by CTHT box were successfully helped to increase the shelf life and quality of fruits. Attractive packaging and careful handling is necessary to reduce the post harvest losses. Pre-cooling by the method by hydro-cooling increased significantly the shelf life of mango fruits without affecting the quality of fruit.Low temperature storage helped to increase the availability of fruits. But chemical changes in fruits were very slow, which reduces its ripening and overall fruit quality. The products prepared from raw and ripe mango fruits revealed good at preparation and throughout the storage period of six months. On the basis of their organoleptic evaluation, it is noticed that they retained their conditions and acceptability during storage period of six months at ambient temperature condition, so there is a scope for processing of Ratna variety.

The minaturization of the components demands to have better machining process which fullfills the demand of tighter allowance and less process effect on component material. Laser Machining is one of the solution to such problems. The book covers various types of lasers, system components and process parameters to be employed for laser machining to obtain the required cut characteristics. The main problems like taper on kerfwall and dross are dealt and solution to eliminate such problems is proposed. Also the application of DOE and Taguchi technique of optimization for kerf width are discussed. The book is useful for graduate students, reserachers and practising engineers
