Abstract: Fractal compression is compression of the lossy type, which is applied for natural textured images. A fractal image compression technique based on the Quadtree algorithm and Huffman coding is proposed in this work. Agonizingly, the term "fractal compression" refers to an image compression technique that uses the fractal geometry of the image data stream to achieve lossy compression. Realistic images and textures are created with the help of this tool. It is based on the fact that parts of an image are frequently similar to other parts of the same image, which allows for faster processing. The most widely used partitioning mechanism is image partitioning in a tree structure. In this emerging world of image processing, quadtree partitioning is a one-of-a-kind technique that divides an image into a set of homogeneous regions. Huffman coding is a type of data compression that is lossless. The Huffman encoding algorithm is introduced through this technique, which creates an alphabetic list of all of the alphabet symbols, which is then arranged in descending order of their likelihood of occurring. The peak signal-to-noise ratio is quite improved by employing the proposed technique, and the encoding time is reduced.

Abstract: Diabetes is a multifactorial disease leading to several complications, and therefore demands a multiple therapeutic approach. Patients of diabetes either do not make enough insulin or their cells do not respond to insulin. In case of total lack of insulin, patients are given insulin injections. Whereas in case of those where cells do not respond to insulin many different drugs are developed taking into consideration possible disturbances in carbohydrate-metabolism. For example, to manage post-prandial hyper-glycaemia at digestive level, glucosidase inhibitors such as acarbose, miglitol and voglibose are used. These inhibit degradation of carbohydrates there by reducing the glucose absorption by the cells. To enhance glucose uptake by peripheral cells biguanide such as metformin is used. Sulphonylureas, like glibenclamide, is insulinotropic and work as secretogogue for pancreatic cells. Although several therapies are in use for treatment, there are certain limitations due to high cost and side effects such as development of hypoglycemia, weight gain, gastrointestinal disturbances, liver toxicity etc. Based on recent advances and involvement of oxidative stress in complicating diabetes mellitus, efforts are on to find suitable antidiabetic and antioxidant therapy. Medicinal plants are being looked upon once again for the treatment of diabetes. Many conventional drugs have been derived from prototypic molecules in medicinal plants. Metformin exemplifies an efficacious oral glucose-lowering agent. To date, over 400 traditional plant treatments for diabetes have been reported, although only a small number of these have received scientific and medical evaluation to assess their efficacy. The hypoglycemic effect of some herbal extracts has been confirmed in human and animal models of type 2 diabetes. The World Health Organization Expert Committee on diabetes has recommended that traditional medicinal herbs be further investigated. The present paper Reviews the Role of Insulike tablets developed by R&D cell of Lactonova Nutripharm Pvt Ltd. Hyderabad in the role of herbal nutraceutical drug INSULIKE, A nutriphenotypic approach for the treatment of diabetes.

Abstract: This review of article is about the removal of Chromium (VI) from textile waste water by using activated carbon prepared from neem leaves and garlic husk. This article presents about adsorption, activated carbon and its process, characteristics of commercially activated carbon, methods to test characteristics of activated carbon, preparation of garlic husk and neem leaves and its adsorbent preparation. Also a detailed study report of physio chemical properties of activated garlic husk powder and neem powder, removal of heavy metal and its toxicity was discussed. The garlic husk powder and neem powder were activated using HCL in which the test results were comparatively same with commercially activated carbon. The particle size, yield, moisture content, ash content and pH of neem and garlic powder were found to be 875 micron and 850 micron, 60.540% and 58.60%, 6.25% and 7.50%, 3.10% and 4.10%, 6.80 and 7.65 respectively. The main scope this project is to remove heavy metals from textile waste water in future with the help of prepared activated carbon using garlic husk and neem leaves. The present study is aimed at preparing the carbon from neem leaves and garlic husk by thermal activation procedure and will be tested for the removal of Chromium (VI) from aqueous solution. The results of the present study suggest that activated carbon from neem leaves and garlic husk can be used beneficially for chromium removal from aqueous solution.
