Econometrics of Scampi (Macrobrachium Rosenbergii) Polyculture in Selected Ponds at Sandeshkhali – I Development Block in North 24 Parganas District of Coastal West Bengal over the Year 2014

Applied Science, Fisheries Economics & Statistics
Abstract: For a social and economic standpoint prawn farming will remain an important part of the rural economy. From an environmental standpoint impacts of intensive prawn culture will only become exacerbated if the discharge of untreated effluent continues. This could have severe consequences for the industry in the future. Alternative systems, such as nutrient recycling systems, or alternative water treatment strategies are necessary to mitigate negative impacts in the future. The potential for higher farm income through remediation of currently idle ponds will provide a significant incentive for farmers to make them back on scampi farming. Factors encouraging prawn farming expansion are compatibility with agriculture, small farmers can practice in their own land, opportunities for wome...

To Detect Types of Adulteration Present in Milk Products

Applied Science, Chemistry
Abstract: Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest other types of food. Early-lactation milk contains colostrums, which carries the mother's antibodies to its young and can reduce the risk of many diseases. Milk contains many other nutrients and the carbohydrate lactose. An emulsion is a suspension of droplets of one liquid into another liquid. Milk is an emulsion of fat in water. Butter is an emulsion of water in fat. The solute is known as the dispersed phase and the solvent is known as the continuous phase. Other examples of emulsions include margarine, mayonnaise, cream, and salad dressing. A colloidal solution is when matter exists in a state of division in between a true sol...

Integral Transform Methods for Inverse Problem of Heat Conduction with Known Boundary of SemiInfinite Hollow Cylinder and Its Stresses

Applied Science, Mathematics
Abstract: Three dimensional inverse transient thermoelastic problem of a semi-infinite hollow cylinder is considered within the context of the theory of generalized thermoelasticity. The lower surface, upper surface and inner surface of the semiinfinite hollow cylinder occupying the space D={(x,y,z)E R3: a≤(x2+y2)1/2 ≤b, 0≤z≤∞} known boundary conditions. Finite Marchi-Zgrablich transform and Fourier sine transform techniques are used to determine the unknown temperature gradient, temperature distribution, displacement and thermal stresses on outer curved surface of a cylinder. The distribution of the considered physical variables are obtained and represented graphically.
