effective treatment for stopping tumour vascularisation.The obtained 457g of Calabash Fruit pericarp was soaked by solvent extraction using 1.5L 95%-Hexane and 1.5L 95%-Ethanol for 24 hours each. The extract was filtered and evaporated using rotary evaporator for 3 hours and further dried for 24 hours. The residual crude extract was poured in a glass container. The extracts were tested through Chorioallontoic Membrane Assay (CAM).The CAM Assay gave the following results. The mesh indices of the different

order to obtain a hydroalcoholic crude extract (HCE)‚ 284.3 grams of propolis were pulverized and macerated in 70% ethanol (m m-1)‚ left in a dark chamber for 7 days at room temperature‚ filtered in vacuum and taken to complete drying in a rotary evaporator with reduced pressure. In order to increase the yield of the extract‚ this extraction procedure was repeated 3 times on the same sample. 50 g of the HCE were dissolved in water and submitted to liquid-liquid partition with solvents of different

OCEAN THERMAL ENERGY CONVERSION Abstract Ocean Thermal Energy Conversion (OTEC)‚ to me‚ is the developing worlds answer to OPEC (Organization of Petroleum Exporting Countries). We will no longer have to depend on oil supplies from other countries. OTEC is an efficient‚ clean process‚ which utilizes the difference in temperatures between the oceans surface and its depths to produce energy. The ocean thermal energy conversion process works something like a refrigerator in reverse. The

Manufacturing Systems Project . Topic : How to manufacture a Refrigerator for long distance transporation of goods. 1.0 Introduction : This project will look at the manufacturing processes involved in producing a refrigerator that allows perishable goods to be transported over long distances. In reality we owe our great choice of foods in supermarkets to this invention. Companies like Thermo King from America have been making refrigerators for many years and are a large supplier of them to

Objective The goal of this experiment is to characterize NaBD4 and NaBH4 using infrared (IR) spectroscopy and melting points. The changes in the spectra due to isotopic labeling are compared to calculated values from the simple harmonic oscillator model. In addition‚ the specific molecular vibration nodes are visualized using computational chemistry software. Introduction The Lewis acid-base is defined simply: acids accept electrons‚ and bases donate electrons. Lewis acids and bases are important

It is anticipated that the demand for Digesters might increase in coming two years as the country will progressively adopt the concept of sludge recycling. There is also increased demand for Evaporators‚ due to Zero Liquid discharge regulation set by the Indian government. Membrane bioreactors employ the membrane technology where a barrier permits the passage certain constituents while preserves other constituents. These equipments therefore

Second International Conference on Emerging Trends in Engineering and Technology‚ ICETET-09 Adsorption Air-Conditioning (AdAC) for Automobiles Using Waste Heat Recovered from Exhaust Gases A C Deshpande‚ R M Pillai Abstract- According to a cautious estimate‚ approximately 10% of the energy available at the crankshaft in a diesel operated vehicle is used for operating the compressor of the vehicle’s air-conditioning system. This is a huge loss if one takes into account the fact that the thermal
