Rajarhat New Town an Urban Perspective: A Case Study of Urbanization, West Bengal, India

New Town Rajarhat is a planned city of West Bengal near Kolkata. Itrsquos also called fast growing planned satellite city in West Bengal. This city is situated in mainly North 24 Parganas, partly South 24 Parganas and eastern side of Salt Lake city. Mainly two types of inhabitants are living here. One type of them who are living from their birth and growing to adjust with the environment which has changed by Government policy and land use patterns. Other type of inhabitants who have come from outside to take land plot or flat for living. They have chosen this area for good services and facilities provided by Govt. So Rajarhat New Town belongs to various stages which are based on the occupational structure of total inhabitants in this area. Surveying, collecting data (primary and Secondary) and information it infer that there are maximum facilities and services which are provided by this type of modern city. Different types of land uses are seen here but itrsquos separated from different area wise. Some of the most important facilities are modern educational institute, IT industry, different cultural centres, modern super speciality hospitals, planned road construction, under construction metro railways, different types of head office, eco-park, Museum of modern art, shopping mall, star category hotels etc. Yet this substantive and original contribution to the study of Rajarhat New Town Municipality critically analysis the Strength and weakness of the Indian urban system and provides new insight into contemporary urban problems. For critical explanation, have been collected different data and sample-survey from old inhabitants who are suffering from this changing environment controlled by Govt. policy, private companies and organizations. It is accepted that Rajarhat New Town is very important planned city in this time after Salt Lake city in West Bengal.nbspnbs

A Comparative Study on Colour and Surface Parameters of Current Esthetic Restorative CAD/CAM Materials

With the development of newer technologies, computer aided design and computer aided manufacturing help immensely in designing, planning and creating a dental prosthesis with the precise 3-D printing technology. Recently, patients are at increasing demand for everlasting colour stability of restorations in such a way that it improves the aesthetic appearance of teeth. CAD/CAM systems are developed to assemble all ceramic materials which restores the aesthetic zone, attributing to the aesthetics and its clinical long-term survivability.A well-known fact that the type, thickness, composition, curing protocols, and polishing methods of resin composites influences the colour characteristics of the restorations. 99 all-ceramic samples with both glazed or polished CAD/CAM were taken into study. The samples were assessed for the surface roughness (Ra) and colour change after immersion in hot and coffee drink and then were subjected to thermocycling for about 30 days. Total samples of 99 among which 33 samples were manufactured from   Vita Enamic, Vitablocs Mark II, and Vita Suprinity.  All the disc were milled uniformly to obtain a standard dimension of 10mm ×10 mm±0.2 diameter and the thickness of the block ranges from 2.0±0.2 mm based on the manufacturer's instructions using a CAD/CAM machine (Amann Girrbach, Germany) and then glazed
