Diversity and distribution of spiders from Gibbon Wildlife Sanctuary, Assam, India
Phalgun Chetia,Dilip Kumar Kalita
Asian Journal of Conservation Biology , 2012,
Abstract: The study describes the identification of the spider assemblages with respect to their diversity and distribution in the semi evergreen forest, Gibbon Wildlife Sanctuary, Assam, India. The paper aims to introduce this neglected Order- Araneae which is primarily unknown to Science particularly in Northeast India. A total of 95 species of spiders belonging to 56 genera and 18 families were recorded during the study from June-August and October-December, 2011. The species were identified using keys for Indian spiders from (Tikader, 1987; Platnick , 2011). Methodology included active searching at all layers from ground level to tree canopy layer accessible easily for hand collecting and visual surveys. This is the first attempt to report the spider assemblages and their microhabitat preferences from Assam, India. Such surveys are vital for conservation of these creatures and building a biodiversity database of this mega diverse group from a fragmented semi-evergreen forest ecosystem in Assam, India. This study is focused on the neglected diversity of spider fauna representing this semi evergreen forest.
TRADITIONAL KNOWLEDGE AND PROBLEMS INVOLVED IN MUGA CULTURE OF ASSAM : A CASE STUDY OF GOLAGHAT DISTRICT

International Journal for Basic Sciences and Social Sciences , 2013,
Abstract: The golden Muga silk Culture of Assam is as old as Assamese culture. Even today it occupies a very important place in life and culture of Assamese people. Muga silk is a symbol of rich Assamese culture and a part of traditional attire of this region. It is a pride of Assam. Presently, Muga culture has been providing bread and butter to nearly 30,000 families in Assam alone. Assam is the largest silk producing state in the country alone contributes about 99% of the total muga raw silk production. The Muga silk cloth is considered as the Queen of all fabric due to its durability and elegant lustrous natural colour. Muga silk is supposed to be one of the costliest fabrics in the textile world. There is a bright prospect of Muga culture in the North –Eastern part of India including Assam.In this article an attempt has been made to highlights the traditional knowledge involved in Muga culture among rearers of Assam and to find out what type of problems they have to faced by this unique culture. The study is based upon both primary and secondary data. The primary data was collected with the help of questionnaires and interview schedule. Secondary sources of data were collected from Regional Sericulture Research Station Rohroiya, Jorhat , Central Muga Eri Research and Training Institute Lahdoigarh, Jorhat, Department of Sericulture Golaghat, Directorate of Economic and Statistics, Golaghat. Data also collect from various books, journals both official and non official records and newspaper etc.
Morphology Based Approach To Recognize Number Plates in India
Phalgun Pandya,Mandeep Singh
International Journal of Soft Computing & Engineering , 2011,
Abstract: Automatic number plate recognition is a real-time embedded system which automatically recognizes the license number of vehicles. Such systems require the localization of number plate area in order to identify the characters present on it. This paper presents an approach based on simple but efficient morphological opening and closing operations for localization of Indian number plates. After localization the skew correction of the number plate is also done for effective segmentation of characters. The number plate skew correction greatly affects the accuracy of the character extraction. The character extraction is based on template matching approach. Our proposed algorithm has been tested on 100 samples and is found to be robust to detect vehicle license plates as well as extracting the numbers with an overall accuracy of 90%.
WORK COMMITMENT AND ABSENTEEISM AMONG THE INDUSTRIAL WORKERS : A SOCIOLOGICAL STUDY OF TWO INDUSTRIES OF NAMRUP, ASSAM.
PARISMITA CHETIA, C. K. GOGOI
International Journal for Basic Sciences and Social Sciences , 2012,
Abstract: This study investigated how work commitment could interact to affect on mindset of industrial workers of two industries of Namrup i.e. Assam Petro Chemicals Limited and Namrup Thermal Power Station which leads absenteeism in both of these industries.
MOLECULAR CHARACTERIZATION OF BACTERIAL SPECIES ISOLATED FROM THE LEAF LITTER OF TECTONA GRANDIS
P Borah*, P Chetia and GD Sharma
International Journal of Bioassays , 2013,
Abstract: Bacteria were isolated by the Dilution Plate Method from the litter of Tectona grandis. The bacteria were identified using biochemical and physiological test. 16s RNA technique was used for molecular characterization of isolated strains. The phylogenetic tree was prepared to understand the evolutionary relationship of the strain with other bacteria. The sequences have been submitted to NCBI, genebank, Canada.
SYNTHESIS AND STUDY OF ANALGESIC, ANTI-INFLAMMATORY ACTIVITIES OF BIS (INDOLYL) METHANES (BIMs)
Partha Pratim Kaishap*, Chandrajit Dohutia and Dipak Chetia
International Journal of Pharmaceutical Sciences and Research , 2012,
Abstract: Gastro-intestinal (GI) toxicity is the common adverse effect which has been associated with most of NSAIDs available in the market. So the search for new therapeutic agents with high margin of safety and freedom from normally associated GI toxic effects has been a priority of pharmacologists and pharmaceutical industries. There are virtually limitless series of structurally novel heterocyclic compounds with a wide range of physical, chemical and biological properties. Literature survey reveals that coupling of two or more biodynamic molecules resulted in the enhanced biological activity. The present work embodied here involves synthesis and evaluation of analgesic and anti-inflammatory activities of some bis (indolyl) methane derivatives.

Atherogenic effect of Arecoline: A computational study
Manabendra Dutta Choudhury,Pankaj Chetia,Karabi Dutta Choudhury,Anupam Das Talukdar
Bioinformation , 2012,
Abstract: There are over 600 million people worldwide covering Asian and Oceanic countries including India have the habit of chewing areca nut as masticator in different forms. Arecoline (C8H13NO2) has been reported as one of the abundant constituents of areca nut. A good number of scientific publications have made Arecoline responsible for oral cancer. Based on observation from clinical situation in North East India, one of the most betel quid chewing region of the country, we suspected a link between consumption of areca nut and Cerebro Vascular Disease like stroke. Therefore, we considered Low Density Lipoprotein (LDL) receptor as target and Arecoline as ligand and studied ligand –target interaction using computational tools. Also we considered High Density Lipoprotein (HDL) receptor as another target to see if Arecoline has any binding potential with it over and above LDL receptor. Docking result indicated that Arecoline and Cholesterol both, have affinity towards extracellular domain of Human LDL receptor but affinity of Arecoline is much higher (-12.3560.) than that of Cholesterol(-0.1810). Docking of Arecoline and 1, 2-Hexyl-1-cyclopentanone thiosemicarbazone (thiosemicarbazone) with Bovine HDL receptor showed that Arecoline also has the potential (Score, -6.2690Kcal/Mol) to block HDL receptor though its potential is less than that (score, -10.0509 Kcal/Mol) of control (thiosemicarbazone). We, therefore, suggest that by inhibiting endocytosis of LDL cholesterol because of blocking LDL receptor function and also by preventing LDL cholesterol uptake by liver from blood because of interference with HDL receptor, Arecoline may contribute to atherosclerosis. The study therefore, indicates a positive correlation between chewing of betel quid and Cerebro Vascular Disease.
