Review On Electric Traction Systems Driving Induction Motor and Associated Power Quality Issues

The traction systems for electric vehicles have advanced considerably over recent years, with the application of different topologies of power converters for the control of various types of electric induction motors and permanent magnet. Furthermore, the evolution of power semiconductor elements of Si to SiC wideband have opened up lines of research and development in this area. The trend of manufacturer’s traction systems is to reach compact systems where the power dissipation is high and the reduction of losses is minimal, for it the implementation of topologies of converters with SiC devices seems to be a good alternative of use to improve the performance of these systems. This paper studies the basic topologies of back to back converter in traction systems als well as the powr quality issues arriving in these systems

Comparative Study of Various Treatments For Dairy Industry Wastewater

Abstract: -Dairy industries have shown tremendous growth in size and number in most countries of the world. These industries discharge wastewater which is characterized by high chemical oxygen demand, biological oxygen demand, nutrients, and organic and inorganic contents. Such wastewaters, if discharged without proper treatment, severely pollute receiving water bodies. In this article, the various recent advancements in the treatment of dairy wastewater have been discussed and stress is given on the lowest cost of the best possible treatment

Herbal medicine : Syzygium cumini :A Review

ABSTRACT Plants have provided mankind with herbal remedies for many diseases for many centuries and even to day. They continue to play a major role in primary healthcare as therapeutic remedies in developing countries. In India herbal medicines have been the bases of treatment and cure for various diseases in traditional methods practiced such as Ayurveda, Unani and Sidha . Syzygium cumini ( syn.Eugenia Jambolana ) commonly know as a " Jamun " having promising therapeutic value with its various phytoconstituents such as Tannins, Alkaloids, Steroids, Flavonoids, Terpenoids, Fatty acids, Phenols, Minerals, Carbohydrates and Vitamins. Its pharmacological actions like hypoglycaemic, diuretics, analgesic, anti-inflammatory, antiplaque, antimicrobial, antidiarrhoel, antioxidant,gastro-protective and astringent to bowels proven on animal models. Most importantly the studies have shown that it protects against the radiation induced DNA damage and it has significantly decreases the fertilizing capacity of the male albino rats, some clinical trial reports are also available for its antidiabetic activity

BIOGRAPHY

hemoglobin is associated with a potent anti-parasitic defense in fish. (Under the direction of Dr. Edward J. Noga.) Innate immunity plays a crucial role in the defense against prokaryotic and eukaryotic pathogens. Major components of this defense are antimicrobial peptides (AMPs). Some AMPs are derived from larger proteins with other recognized functions (e.g., lactoferrin, histones). In this study, we demonstrate the expression of peptides homologous to the β-chain of hemoglobin (Hb-β), one of the two major subunits of this respiratory protein. These Hb-β peptides (HbβP-1,-2 and-3), isolated from gill of the economically important channel catfish (Ictalurus punctatus), had antibacterial activity and were upregulated in gill and skin epithelium in response to parasitic (Ichthyophthirius multifiliis, ich) infection. One peptide (HbβP-1), while having relatively weak antibacterial activity had antiparasitic activity comparable to that of other potently antiparasitic AMPs. Also, this cidal activity was specifically directed against the trophozoite (trophont) stage of ich at a low concentration (6.2 μg/ml, 1.7 μM) but had no apparent effect on the disseminative (theront) stage or the reproductive (tomont) stage at the highest concentration tested (400 μg/ml, 108 μM). In addition, HbβP-1 was not lytic to channel catfish erythrocytes at the highest concentration tested (400 μg/ml, 108 μM). Immunohistochemistry and in situ hybridization of skin and gill from fish experimentally challenged with ich indicated that the HbβP-1 sequence was both synthesized and expressed in epithelial tissues of skin and gill, which are the target tissues for ich. “Bug blots ” of gill extracts from fish recovering from a bacterial infection suggested that upregulation of these Hb-β related peptides might also occur with other infections. These findings, along with the recent discovery by others that Hb-β is expressed in mammalian macrophages and alveolar epithelium, suggest that hemoglobin-derived AMPs might play a significant role in the non-specific immune response of vertebrates

Clustering Moodle Data As a Tool For Profiling Students Existing System

Abstract We wish to create system that will gather information related to e-learning courses and performing analysis on the data. In this system analysis, clustering and prediction on data is performed to generate results, which makes monitoring data easier. The aim of our project is to use the methods of data mining, machine learning to given students better tools to help their e-learning courses.In this system processing of Moodle data is to be carried out.This project includes online tests, quizzes, displaying notifications, assignments submission ,calculating grades,attendance sheet generation etc. Keywords:Datamining,Clustering,Prediction,Machine learning Problem Definition To make monitoring easier, we will provide reliable statistics, behavior groups and predicted results.In this step of the project, we are clustering students by mining Moodle log data. A first objective is to define relevant clustering features. A second objective is to determine if our students show different learning behaviours. We will experiment whether there is an overall,ideal number of clusters and whether the clusters show mostly qualitative or quantitative differences. Experiments in clustering were carried out using real data obtained from various institute using Moodle platform

Notes for genera – Ascomycota

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)
