Precise mapping of Kaziranga National Park (KNP), the natural world heritage site, is the prime objective of this paper. High resolution Indian remote sensing satellites including IRS P6 Panchromatic and LISS 4 image, with 2.5 m and 5.8 m spatial resolution respectively, were used for the same along with GPS and extensive field survey. A theme based hybrid approach was followed for classification of digital remote sensing images. The overall classification accuracy was estimated to be 91.7% where as K value implies that the classification process was avoiding 89.9% errors of a hat completely random classification. The Eastern alluvial grassland is found to be the predominant vegetation type which occupies 50.6% of the total park area. Semi-evergreen and moist mixed deciduous forests together occupy 21.8% of the total area followed by short grass (7.7 %). A substantial area (11.7%) was found to be eroded in to the river Brahmaputra and as a result core area of the park is found to be decreased when compared with previous assessments.Keywords

Certain aspects of regional metamorphism of East Antarctica granulite terrain in the Humboldt Mountains are revealed through a study of the grain size of garnets and chemical zoning present in them. The Ferry and Cashman approach to grain size (Crystal size Distribution-CSD) development and Walther and Wood approach of grain growth are utilised to draw intersting conclusions. The growth of garnets was slower in the deeper levels but produced large, chemically unzoned grains.Keywords

The present paper deals with the status of the Cololejeunea (Spruce) Schiffn. in Nilgiri hills of Western Ghats. Till date the genus is represented in Nilgiri hills by 5 species Cololejeunea nilgiriensis G. Asthana & S. C. Srivast., C. latilobula (Herzog) Tixier, C. minutissima (Sm.) Schiffn. C. appressa (A. Evans) Benedix and C. pseudofloccosa (Horik.) Benedix. Recent investigations have however, shown the presence of two more species, C. udarii G. Asthana & S. C. Srivast. and C. cardiocarpa (Mont.) A. Evans.Keywords

Information about the occurrence of antibiotic substances in bryophytes and the medicinal use of bryophytes are sporadic, particularly in India, in comparison to developed countries. Despite of a long history of medicinal use of bryophytes by various tribal and local communities across the world, their significant utilization in medicines is still a dream due to lack of concise ethnobotanical information, scarcity of material, degrading habitats etc. Present article is an attempt to create awareness about this group of plants.Full Text

Objectives: This paper represents the design and simulation of LNA (Low Noise Amplifier) for ISM (Industrial, Scientific and Medical) applications operating in the 2.4-2.5 GHz band. Methods/Statistical Analysis: In this paper, a very accurate topology named inductive source degeneration topology has been used to provide low NF (Noise Figure), high S21 (forward gain) and very low Power Consumption (PC). The simulation was made through using Advance Design System (ADS) software. Findings: The proposed work prominence on reduction in Noise Figure with increase in power gain at low power consumption as compared to published previous results at 1.2 V power supply. Improvements: This is done in three steps (three different schematic designs) i.e. start with very basic LNA design to proposed LNA design and presents the comparison of all three designed circuit simulations.Keywords
