Rapid Prototyping (RP) refers to a class of technologies that can automatically construct physical models directly from Computer Aided Design (CAD) data. RP is also called layer-manufacturing technology. Prototype parts and tooling can be produced in a shorter time thereby reducing the lead-time for product development. Different rapid prototyping technologies are commercially available in the market, each with unique capability. Stereo-lithography (SL), Fused Deposition Modeling (RDM), Laminated Object Manufacturing (LOM), Selective Laser Sintering, and Direct Metal Laser Sintering are some of the commonly used Rapid Prototyping technologies. This paper deals with the capabilities of the above technologies with reference to the maximum size of part, surface finish and accuracy. Also, a case study of the injection moulding tool produced by Direct Metal Laser Sintering RP technology is discussed.

Cam type grinding wheel dressing attachments, in which the X and Y motions of the dressing diamond are controlled independently by templates, facilitates fast, accurate and automatic contour dressing, the design of the templates could be done in such a way that the peripheral speed of the diamond could be kept constant and also to cover wide range of grinding wheel profiles. This paper describes the development of templates for grinding splines and gears using cam type wheel dressing attachment.- Correlation Analysis Between Profile Characteristics of Maize Farmers and Their Extent of Adoption of Recommended Package of Practice of Maize in Mahmud I Raqi District of Kapisa a Province of Afghanistan

Maize (Zea mays L.) has become a staple food crop in many parts of the world, with total production surpassing that of wheat or rice. However, all this maize is consumed as food, animal starch and ethanol produce etc. As food and feed it is consumed directly as green cob, roasted cob or popped grain. Its grain can be used for human consumption in various ways such as corn meal, fried grain and flour. Maize grain has high nutritive value containing 66.2 per cent starch, 11.1 per cent protein, 7.12 per cent oil and1.5 per cent minerals. In addition, it contains 90 mg carotene 1.8 mg niacin 0.8 mg thiamine and 0.1mg riboflavin per 100 g grains. An ex-post facto research design was used in present investigation. The study was confined to Mahmud I Raqi district of Kapisa one of the province of Afghanistan. From this district four villages were randomly selected. From each village 30 samples were randomly drawn. In this way, the sample size for the study comprised of 120 respondents. Twelve independent and one dependent variable were taken for the study. The data were collected by personal interview method through structured interview schedule and analyzed by correlation co-efficient.Keywords
