COLOR HISTOGRAM BASED MEDICAL IMAGE RETRIEVAL SYSTEM

This paper aims to focus on the feature extraction, selection and database creation of brain images for image retrieval which will aid for computer assisted diagnosis. The impact of content-based access to medical images is frequently reported but existing systems are designed for only a particular context of diagnosis. But, our concept of image retrieval in medical applications aims at a general structure for semantic content analysis that is suitable for numerous applications in case-based reasoning. By using the features, the database created for comparison. The color histogram is used to measure the similarity between the stored database image and the query image. The image which is more similar to the query image is retrieved as the resultant image. If the quer

MODIFICATION TO SPIHT ALGORITHM USING INCREMENTAL THRESHOLD FOR IMAGE COMPRESSION

The Modified SPIHT represents a more efficient implementation of the SPIHT algorithm by using variable thresholds to sort the list of insignificant pixels (LIP) and the list of insignificant sets (LIS). We observe two interesting facts: (I) most of the initial subsets in LIS are not only insignificant with respect to the maximum threshold, but also insignificant with respect to the smaller threshold. And (2) Most of the pixels generating from sorting LIS are smaller than the current threshold. Based on these two observations, it represents a new image codec method, which can make the binary encoded outputs more efficient, and can work well on different image sizes and different decomposition levels

NUMERICAL ANALYSIS OF A HEAT SINK WITH DIMPLES

In this paper, a numerical simulation is carried out to analyse the heat transfer performance of copper channel. COMSOLMULTIPHYSICS commercial software is used for the analysis. The material chosen for the channel is copper because of its good thermal properties. A channel with dimples on its base is chosen for the analysis. The heat transfer of the microchannel is found to increase with the use of dimples.Â

Isolation, Screening and Characterization of Exopolysaccharide Producing Pseudomonas Sp. from The Soil Sample

  Exopolysaccharides (EPS) are vital metabolites that specific environmental microorganisms produce and expel. The goal of the current investigation is to identify bacteria that produce exopolysaccharides in soil samples from the Buttenath Dam region, At. Chanai, Tq. Ambajogai, Dist. Beed situated in the Marathwada region of Maharashtra, India. Two methods, such as gravimetric analysis of exopolysaccharide dry weight and quantification as, instance, for total carbohydrate content using phenol sulphuric acid technique, were used to screen the EPS-producing capacities of the chosen isolates. Post preliminary screening by selecting thick, ropy-like colony formers on agar medium, the results showed that thirteen (13) distinct colonies were marked to manufacture EPS. Tentative identification of these isolates was done based on morphological and biochemical tests. Three (03) isolates, VJ001, VJ003 and VJ010, were identified through secondary screening as the most effective EPS producers (producing precipitates over 1.46 mg/L of total dry weight and 8). This was in comparison to other bacterial colonies that were also isolated. Out of these screened isolates, VJ003 was the isolate with the highest exopolysaccharide produced and this isolated bacterium was identified using 16S rRNA gene sequence and phylogeny study as Pseudomonas aeruginosa VJ003 with NCBI GeneBank accession no. OR196093. The Pseudomonas aeruginosa VJ003 strain can be used in biotechnological sectors because of the ability it has to create significant levels of exopolysaccharides, according to the results of the current study

Evaluation of Hybrids and Cultivars of Single type Tuberose (Polianthes tuberosa)

Hybrids and cultivars of single type tuberose was evaluated to fulfill the need to develop new hybrids as demanded by commercial growers. Evaluation of fifteen genotypes showed significant variation in growth, floral and bulb characters. Cultivar Arka Prajwal was significantly superior over all genotypes, which recorded least number of days for opening of 1st floret (78.55 days) with maximum diameter of spike (1.18 cm), length of floret (6.05 cm), weight of individual floret (3.12 g) and weight of spike (121.43 g).The hybrid genotype L1P4 (Variegated X Phule Rajani) was observed to be superior in terms of rachis length (39.78 cm), inter-nodal length (7.25 cm), length of bulb (8.09 cm), diameter of bulb (3.76 cm) and diameter of bulb-lets (1.85 cm). Among the hybrid genotypes L1P4 also recorded maximum plant height (116.39 cm), spike length (109.58 cm), weight of cut spike (105.08 g) and vase life (11.00 days). However, it was foundto be at par for number of florets per spike (57.25), length of floret (5.92 cm) and number of spikes per clump (10.14) with all other cultivars and hybrids tested. From the overall performance, it was found that the cultivar Arka Prajwal was the best. Genotype L1P4 found promising for loose as well as cut flower production because of its number of florets, inter-nodal length and spikes per clump which are important characters considering loose flower for taking maximum number of pickings. However, characters such as rachis length, spike length, vase life and weight of spike which are imperative for cut flowers are also noted superior in genotype L1P4

Documentation and ethnobotanical survey of wild edible plants from Kolhapur district

The present study deals with the identification, documentation and ethno-botanical exploration with respect to food value of wild edible plants from Kolhapur district. Total 50 wild edible plants were surveyed. Edible parts of wild plants (fruit, flower, leaves, tubers and inflorescences) are the nature’s gift to mankind; these are not only delicious and refreshing but also the chief source of vitamin, minerals and protein. The wild edible plants are the normal food of cattle grazers and the forest tribes. Although the popularity of these wild forms of fruits, flowers and tubers has declined, it is considered that special attention should be paid to them in order to maintain and improve this important source of food supply

DESIGN, DEVELOPMENT AND CHARACTERIZATION OF MUCOADHESIVE GASTRO SPHERES OF CARVEDILOL

Objective: The purpose of this study was to design mucoadhesive gastro spheres of carvedilol targeting to upper GIT, and optimize it in terms of its entrapment efficiency and drug release. A 32 full factorial design was employed to study the effect of independent variables like sodium alginate and sodium carboxyl methyl cellulose on entrapment efficiency and in vitro drug release. Methods: Mucoadhesive gastro spheres were prepared by Orifice-Ionic gelation method, in which drug is uniformly distributed in the polymer solution so drug can be loaded easily in the polymer.32 full factorial designs were used to study the effect of process variables on formulation characteristics by applying statistical analysis. Results: FTIR, XRD and DSC analyses apparently did not indicate any interaction of the drug with the polymers. However, the drug content, drug entrapment efficiency and morphology of the gastro spheres were found to be influenced by the method of preparation, composition of gastro spheres as well as exposure to the cross linking agent. In vitro drug release study showed that drug release can be modified by varying drug to polymer ratio. The release rate was found to be decreased in accordance with the increase in the ratio of polymer used. Conclusion: From the study, we successfully developed carvedilol gastro spheres by using mucoadhesive polymer like SCMC and rate retardant sodium alginate polymer
