This study investigated the use of pressure cooking with different retrieval solutions at variable pHs to determine the optimum protocol for the extraction of high quality DNA from formalin fixed paraffin embedded (FFPE) tissues. Further, the oxidation effect on the archived FFPE tissues in relation to the age of the tissue blocks was also explored. The main aim of the study was to investigate ...

Although color averaging techniques are widely used in content based image retrieval system because of its computational simplicity and effective retrieval, color averaging technique still suffer in identification of different objects which share the same average color information. To overcome this limitation of color averaging technique, a new technique based on block color averaging is propos...

Information Extraction has become an important task for discovering useful knowledge or information from the Web. A crawler system, which gathers the information from the Web, is one of the fundamental necessities of Information Extraction. A search engine uses a crawler to crawl and index web pages. Search engine takes into account only the informative content for indexing. In addition to info...

background: abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. objective: in this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hcg) administration. materials and methods: a total of 985 metapha...

In this paper, a robust feature extraction technique for content based image retrieval proposed. Most of the research scholars do with the different feature extraction for feature extraction techniques to enhance image retrieval recognition efficiency. Content based image retrieval algorithms concentrate on the local meannearest neighbor classifier and use its decision rule to supervise the des...

Compressed domain image retrieval is going to play an increasingly important role in the future. It allows the calculation of image features and hence content-based image retrieval (CBIR) to be performed directly on the compressed data without the need of decoding it beforehand. The Colour Visual Pattern Image Coding (CVPIC) technique represents a compression algorithm where the compressed form...

introduction: we aimed to compare apical canal transportation of extracted teeth and two types of simulated resin blocks. materials and methods: mesiobuccal root of extracted maxillary molars, high hardness simulated resin blocks (knoop hardness=40) and low hardness simulated resin blocks (knoop hardness=22) were prepared with k-files using step-back technique (n=15 canals in each group). doubl...

-In present time, digital image libraries and other multimedia databases have been suddenly expanded. Therefore Semantic gap that between the visual features and human semantics has become very important area of research known as content based image retrieval (CBIR). If there is a need of retrieving an image from a large image database effectively and precisely, the development of content-based...
