Depth Segmentation Method for Cancer Detection in Mammography Images

Breast cancer detection remains a subject matter of intense and also a stream that will create a path for numerous debates. Mammography has long been the mainstay of breast cancer detection and is the only screening test proven to reduce mortality. Computer-aided diagnosis (CAD) systems have the potential to assist radiologists in the early detection of cancer. Many techniques were introduced based on SVM classifier, spatial and frequency domain, active contour method, k-NN clustering method but these methods have so many disadvantages on the SNR ratio, efficiency etc. The quality of detection of cancer cells is dependent with the segmentation of the mammography image. Here a new method is proposed for segmentation. This algorithm focuses to segment the image depth wise and also coloured based segmentation is implemented. Here the feature identification and detection of malignant and benign cells are done more easily and also to increase the efficiency to detect the early stages of breast cancer through mammography images. In which the relative signal enhancement technique is also done for high dynamic range images. Markovian random function can be used in the depth segmentation. Markov Random Field (MRF) is used in mammography images. It is because this method can model intensity in homogeneities occurring in these images. This will be helpful to find the featured tumor DOI: 10.17762/ijritcc2321-8169.15023

Micro Food Processing Enterprises of Andhra Pradesh: Growth Opportunities Using the PEST Analysis

Aims: This study aims to use PEST analysis to comprehend the strategies implemented by micro food processing enterprises in Andhra Pradesh, India, with regard to political, economic, social, and technological factors to provide an overview of their growth potential. Study Design: This study is designed as an observational study, utilizing both secondary and primary data. Methodology: The study uses PEST analysis, which is a framework used to analyze and understand the external macro-environmental factors that affect an organization. Secondary data was obtained from the Andhra Pradesh Food Processing Society (APFPS), while primary data was collected from micro food processing enterprises in Andhra Pradesh. Results: Based on the study's observations, it was found that the state government of Andhra Pradesh provides a favorable and friendly environment for initiating an enterprise by providing subsidies and incentives. Additionally, micro food processing enterprises adopt specific strategies to sustain competition. Andhra Pradesh was found to be the top South Indian state in net value-added products

Occurrence of a rare lambridiform fish, Desmodema polystictum (Ogilby, 1898) from Andaman coast of India

The present study reveals the first documented distribution record of Desmodema polystictum (Ogilby, 1898) from the Andaman coast, eastern Indian Ocean. The species is rare in nature and the knowledge regarding the taxonomy, ecology and distribution is still limited. Only few records have been come from the Indian Ocean. The study is based on a single specimen (34 cm total length) collected from the northeastern region of Andaman Islands, India. The present record of D. polystictum from Andaman waters provides greater latitude and depth distribution than previously acknowledged from the Indian Exclusive Economic zone. Along with the comparative morphometric and meristic data from previous reports, description of present specimen as well as distributional information are also provided and discussed

Live feed - Zooplanktons

The rotifers, Brachionus plicatilis and B. rotundiformis are widely employed for feeding marine fish larvae. Its body size ranging from 70 - 350 microns, (depending on strain) makes these organisms an appropriate prey to start feeding after the resorption of the yolk. Rotifers are used as first food during a few days or weeks depending on the reared species. The main advantages of rotifers include – 1). High population growth rate, 2). Filtration of particles in suspension, 3). A good tolerance to culture conditions and handling, and 4). Appropriate energy content and reasonable nutritional value. In addition, it is relatively modifiable by dietary manipulation by means of postculture enrichment

Differentiation of two Chlorophthalmus species Chlorophthalmus corniger (Alcock, 1894) and C. acutifrons (Hiyama, 1940) based on otolith morphometry

A comparative morphometric analysis of otoliths was done to understand the major morphometric characters responsible for differentiating two species of Green-eyes (Chlorophthalmus corniger and C. acutifrons) which is one of the dominant fish groups caught in the deep-sea trawling during the exploratory surveys as well as in the by-catch of trawlers targeting deep-sea shrimps at a depth range of 300 – 500 m in the Indian waters. A total of 53 intact, right otoliths (25 and 28 for C. corniger and C. acutifrons, respectively) were considered for the morphometric analysis to differentiate species collected from Andaman Sea. The study extracted four otolith morphometric measurements and five shape indices measured from the otoliths using image analysing software including otolith weight. The otolith morphometric parameters and shape indices showed significant relationship with the fish size were scaled with standard length to remove the influence of fish size from the data. Principal component analysis using scaled otolith morphometric measurements indicated that the first two axes described 84.78 % and 11.80 % of variation, respectively. The PC1 differentiated the species based on ellipticity and otolith weight followed by area and perimeter. C. acutifrons is differentiated from their congener with a more elliptic, heavy otolith with more otolith surface area. One-way PERMANOVA confirmed significant difference in otolith morphology between the species. Present study confirmed the suitability of otolith morphometric analysis in differentiating Chlorophthalmus species which are quite inevitable for taxonomic studies as well as for the better understanding of the species resolution in diet studies

Microalgae as live feed

The development of mariculture is fully dependent on the availability seed of the fish or shell fish to be cultured. For this, hatchery production of the seed is imperative owing to the uncertain nature of natural seed resources. At present the seed production technology of some species with mariculture potential have been developed in India, which includes Cobia, Rachycentron canadum, Silver/Snubnose pompano, Trachinotus blochii, Indian pompano, T.mookalee, Orange spotted grouper, Epinephelus coioides, Sea bream, Lethrinus lentjan, Asian sea bass, Lates calcarifer etc

Reprinted with permission.Among the survivors of Ebola virus disease (EVD), complications that include uveitis can develop during convalescence, although the incidence and pathogenesis of EVD-associated uveitis are unknown. We describe a patient who recovered from EVD and was subsequently found to have severe unilateral uveitis during convalescence. Viable Zaire ebolavirus (EBOV) was detected in aqueous humor 14 weeks after the onset of EVD and 9 weeks after the clearance of viremia.Supported by a grant from the National Center for Advancing Translational Sciences of the National Institutes of Health (UL1TR000454, to the Atlanta Clinical and Translational Science Institute), an unrestricted grant from Research to Prevent Blindness and a grant from the National Eye Institute (P30-EY06360, to the Department of Ophthalmology, Emory University School of Medicine), and a fellowship grant from the Australian Research Council (FT130101648, to Dr. Smith).
