American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.37115
Abstract: Abiotic stresses can directly or indirectly affect the physiological status of an organism by altering its metabolism, growth, and development. The leaf growth and Chlorophyll content has significantly shown to vary from the control ones while the grain yield was not affected. While many plant species naturally accumulate proline and protein as major organic osmolytes when subjected to different abiotic stresses. These compounds are thought to play adaptive roles in mediating osmotic adjustment and protecting sub cellular structures in stressed plants. Different approaches have been contemplated to increase the concentrations of proline like compounds in plants grown under stress conditions to increase their stress tolerance. Seven different traditional rice varieties of Assam were evaluated for their response to osmolyte production under physiological drought condition through simulation at three levels of osmotic stress of 0.15 bar, 0.25 bar and 0.56 bar of physiological drought initiated by polyethylene glycol (PEG 6000). Along with the evaluation for osmolyte response the different components of genotypic variation for six different drought-sustaining characters in the seven rice varieties were also substantiated. The results indicated that plant height and seed number have significant genotypic coefficient of variability (GCV) and heritability. Verities like Laodubi, Leserihali, Beriabhanga and Borah were screened out as the best drought sustaining variety.

“Self-concept And Academic Achievement Of The Tea-tribe School Going Adolescents In Lakhimpur District Of Assam”
Manju Chutia
Indian Streams Research Journal , 2012,
Abstract: The title of the present study comprises with three key terms 'Self concept', 'Academic achievement' and 'Tea-tribe'. An individual's general composite or collective view of him or herself across multidimensional sets of domain specific perceptions, based on self-knowledge and evaluation of value or worth of one's own capabilities formed through experiences with and interpretations of the environment (Eccles, O'Neill, & Wigfield, 2005). Self-concept is the perception that individuals have of their own worth. The term academic achievement refers to educational performance of the students studying in schools. It indicates how far they are successful in acquiring knowledge, understanding and skills in different subjects imparted to them in the schools. In this study the self concept and the academic achievement of the tea-tribe school going adolescents were studied. Here the tea-tribe refers to the people the British tea planters brought to Assam to work in the tea gardens they started in the state. The socalled Tea-tribes of Assam were brought in by the colonial planters (British) as indentured labourers from the Nagpur region.The British tea planters brought the tribal people ( the Adibasis) and some general castes people also (like the Kurmis, Tantis ete.) from different parts of Bihar, the present Jharkhand, West Bengal, Chattisgarh, Madhya Pradesh, Andhra Pradesh. In this study the significant difference between the boys and girls school going adolescents was studied.The significant difference between the self concept of the school going adolescents of tea garden worlers and non tea garden workers was also studied.

Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43031
Abstract: There is growing needs for web based GIS for easy and fast dissemination, sharing, displaying and processing of spatial information which in turns helping in decision making for various natural resources based applications. In order to make a cost effective implementation, operation and maintenance of spatial information over the web, a cheaper yet feature rich alternative to commercial software is required which can be fulfilled by Open Source GIS software. This paper conveys an efficient approach to customize and integrate an open source web GIS system based on Mapserver as a web GIS server and PostgreSQL/PostGIS as an object oriented relational database management system (ORDBMS) for effective dissemination, sharing and management of spatial information over the internet. An open source web application tool built on top of MapScript using the PHP programming language has been used as for development of interactive user interface. The configurable Web Mapping Client Components (CWC2) tags have been added to HTML template pages in order to deploy the mapping contents to a web application. It is observed that the present system developed using open source software enables user to view, update, customized retrieval, query and analysis of natural resources information for specific needs.
A Geospatial Approach to Climatic Zone Specific Effective Horticultural Planning in East Khasi Hills District of Meghalaya, India  [PDF]
Jonali Goswami, Dibyajyoti Chutia, S. Sudhakar
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43032
Abstract: Climatic zone is one of the most important units for horticultural planning. Survival and failure of particular land use or farming system in a given region heavily relies on careful assessment of agroclimatic resources. Large variety of crops is being grown in Meghalaya traditionally, based on the needs and cultural practices of people without any consideration to the suitability of the climate. This study attempts to make adjustments with the climate based upon scientific knowledge to make the best use of the natural resources so as to recommend more area under horticultural crops. This has been made by identifying existing land use and appropriate land use strategies mainly for horticultural crops for each agro-climatic region. Modern Geospatial technology such as satellite Remote Sensing (RS) and Geographical Information System (GIS) and GPS have been used effectively to provide newer dimensions in identifying suitable sites for various horticultural crops and also for appropriate monitoring and management of land resources in an integrated manner with reference to agro-climatic condition.

Abstract: This paper presents an Object oriented feature extraction approach in order to classify the linear features like drainage, roads etc. from high resolution Indian satellite imageries. It starts with the multiresolution segmentations of image objects for optimal separation and representation of image regions or objects. Fuzzy membership functions were defined for a selected set of image object parameters such as mean, ratio, shape index, area etc. for representation of required image objects. Experiment was carried out for both panchromatic (CARTOSAT-I) and multispectral (IRSP6 LISS IV) Indiansatellite imageries. Experimental results show that the extractionof linear features can be achieved in a satisfactory level throughproper segmentation and appropriate definition & representationof key parameters of image objects.

Abstract: Schools play a pivotal role in shaping the life of an individual as well as in bringing about socio-economic and cultural changes and progress of society. The modern time and changing situation has made the role of school even more significant. The success of any educational institution largely depends upon the quality education that is provided by the institution to the students. Inequalities between Rural and Urban areas are not new. They have always existed. In the present times it has become a vital problem of the society. Though the world has become a small village in this Era of Globalization this type of disparities still exist in our society. Present study tried to trace out the rural urban disparity of the academic achievement of the students in secondary schools of Kamrup district.
Scaling Theory for Conical Surrounding-Gate MOSFET
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: In this paper, we present scaling theory for conical Surrounding-Gate MOSFET which was derived from the cylindrical form of Poisson's equation assuming parabolic potential profile in the radial direction. For performance estimation, device simulation is done and the data were compared with some existing model of cylindrical as well as Double Gate MOSFET. Subthreshold swing and DIBL effects were simulated for this developed model and wascompared with cylindrical and DG structure and found that conical structure gives better immunity to the short channel effect.

Abstract: The diversity of Penicillium spp. and associate mycobiota from different virgin forest floor in the Brahmaputra Valley, Assam, India was analyzed. Soil samples were collected from six different undisturbed forest floors together with seasonally flooded forest and also from agricultural fields. Samples were taken from the litter and from three soil core i.e. 0-5, 10-15 and 30-35 cm in depth. The isolated fungal species were identified based on morphological and reproductive characteristics. About 18 common fungal species from different soil samples were isolated dominated by Penicillium sp. and Aspergillus sp. The total fungal population found in the studied sites was 98.87 (±10.7) x103 CFU/g dry soils in all the seasons in top soils. The total CFUs of Penicillium were also highest among the species in all the sites (mean 18.73 ±1.1 x103 CFU/g; n=7) where 27.2 x103 CFU/g in summer and 11.6 x103 CFU/g dry soil in winter. Relative density of Penicillium sp. was also higher among the associated fungi although relative density of Aspergillus (23.83) was higher than Penicillium (19.39). Among the 30 isolates of Penicillium, few species have shown antimicrobial activity against the tested bacterial pathogens. The cultural filtrate of four different isolates showed antimicrobial activity against Streptococcus bombycis, Aeromonas salmonicida, Staphylococcus aureus and E. coli having inhibition zone of about ≥10mm. All the tested bacterial species were sensitive to six different Penicillium spp.
Multiscale theory of valley splitting

Physics , 2008, DOI: 10.1103/PhysRevB.77.193311
Abstract: The coupling between $z$ valleys in the conduction band of a Si quantum well arises from phenomena occurring within several atoms from the interface, thus ruling out a theoretical description based on pure effective mass theory. However, the complexity and size of a realistic device precludes an analytical atomistic description. Here, we develop a fully analytical multiscale theory of valley coupling, by combining effective mass and tight binding approaches. The results are of particular interest for silicon qubits and quantum devices, but also provide insight for GaAs quantum wells.
