he infrared and Raman spectra of m-nitroanisole have been recorded and analyzed. The vibrational wavenumbers were calculated theoretically using Gaussian03 set of quantum chemistry codes. The data obtained from vibrational wavenumber calculation are used to assign vibrational bands found in the infrared and Raman spectra of the studied molecule.

Availability of surface & ground water and firewood is attenuation in many regions. In the study area is the same problem to shrinking the water. The study has also revealed that the GIS techniques are time/cost-effective and can be employed successfully in the planning stages of a ground-water exploration programme. In addition, the GIS data generated for the study of ground-water prospects can be updated and used for the planning and management of ground-water resources of the area of study. Huge geo-scientific data related to various ground-water parameters provide enormous scope for using the Geographic Information System (GIS) to draw meaningful conclusions on the ground-water prospects of an area. To demonstrate the efficiency of the GIS for ground-water studies, information on the parameters controlling ground water such as lithology, geomorphology, structure, and recharge condition of study area were analyzed using ARC GIS environment. Existing maps and records were used as data. Different thematic layers are prepared using remote sensing and GIS for the assessment of water resources status. The union shape file of land use / land cover, geology, geomorphology, soil and slope status maps have been incorporated in the Arc GIS as input maps. The existing water resource classes have been reclassified according to the standard statement, five classes of water resources can be regrouped into three classes such as good, moderate and poor status of water resources in the study area. Overall results show that nearly about 50% of the geographical area has good and moderate resources. Another major part of poor resource areas need to be reclaimed to restore and improve its resource status. Management plan has been suggested.

A detailed analysis has been carried out to the effects of magnetic cloud events with and without association of interplanetary shocks. Ninety-six magnetic clouds are identified during the period from 1996 to 2007 using the superposed epoch analysis. The solar wind velocity and interplanetary magnetic field enhanced ahead of magnetic cloud that are preceded by a shock. A large decrease in cosmic ray intensity is noticed during the passes of interplanetary shock associated magnetic clouds.

This paper deals with the study of heat transfer in the rotational flow of a visco-elastic liquid due to rotation of an infinite porous disk in the presence of heat sources. Constitutive equations of the problem have been developed in order to formulate the problem under the prescribed boundary conditions. Runge-kutta technique of numerical integration has been used to solve the non-linear equations of motion and energy. Velocity and temperature profiles have been shown by graphs whereas the values of skin-friction and rate of heat transfer have been entered in tables. It is observed that drag on the disk in larger in case of non-Newtonian fluid than Newtonian fluid. Increase in the permeability parameter increases the rate of rotational flow of the visco-elastic fluid. The Reynolds number (R₁) raises the temperature at any point of the fluid.

The IR and Raman spectra of 3-cyclohexene-1-carboxylic acid have been recorded and analyzed. Geometry and harmonic vibrational wavenumbers were calculated theoretically using Gaussian03 software package. Calculations were performed at the Hartree-Fock and DFT levels of theory using the standard 6-31G* basis. The calculated wavenumbers (B3LYP) agree well with the observed wavenumbers. The data obtained from vibrational wavenumber calculations are used to assign vibrational bands found in the IR and Raman spectra of the studied molecule. The calculated first hyperpolarizability is very high and the studied molecule may be an attractive object for further studies on non linear optics. The predicted infrared intensities and Raman activities are reported.

Evaluations in general theory of relativity have provided an interesting phase picture for the black hole- black string phase transition. We are interested to present microscopic picture for the black hole of (4+1) dimensional near-extremal holes and (3+1) dimensional near-extremal holes for the compactification radius is very large or very small respectively.

Heavy minerals from Barail sandstones occurring in and around Mandardisa of N.C. Hills, Assam have been studied to determine the provenance (source) depositional history and maturity of the sandstones. An attempt has also been made to correlate the area with some neighbouring areas of Meghalaya and Assam where Barail sandstones are well exposed. The heavy mineral assemblage contains a good amount of stable and unstable minerals consisting of non-opaque minerals viz. zircon, tourmaline, rutile, epidote, staurolite, kyanite etc. and opaque iron minerals. This assemblage suggests that the sediments of Barail sandstones were derived mostly from metamorphic and igneous rocks with minor derivation from sedimentary rock. The source rocks are mostly from neighbouring areas of Meghalaya Plateau and Arunachal Himalaya. The statistical analyses namely length frequency breadth frequency and elongation quotient frequency diagrams of zircon indicate two or more diverged provenance (sources). The scatter diagram of zircon is also indicative of nearer provenance and hence shorter transportation of the sediments from the sources. The study of primary and secondary growths of zircon grains also indicate dual nature of origin of the sandstones. A very few grains of rounded heavy minerals suggest reworked nature of some sediments.

We have investigated the spacetime singularities in the gravitational collapse of anti-de-Sitter-Husain spacetime. We obtained that spherically symmetric anti-de-Sitter-Husain spacetime contradicts the cosmic censorship conjecture (ccc) whereas non-spherical collapse respects it.

In India, Tamilnadu coast extends to a length of about 1026 km. Coastal zone is the transition between land and sea, one of the most fragile, complex and productive ecosystem. It is bestowed with enormous resources, both living and non-living, potential area for recreation and harnessing non-conventional energy resources (wave and wind energy). Widely varying nature of landforms and their disposition along the beaches and inland represent the successive phases of transgression and regression of sea level. The analyzed sediments exhibit a good sorting under high energy environment. Most of the samples were brought by beach and Aeolian processes and deposited by shallow agitated water in a turbid environment.

 Environment is always kept on changing over a period due to the changing climatic and physiographic factors. These factors influence marked effects upon the genetic and phenotypic machinery that brought about by various intracellular and extracellular factors which operating throughout the life history of organisms. These factors elicit genetic responses that ultimately manifest themselves through a morphological and physiological modification of the phenotypes. The genus Scenedesmus is well known for its extreme phenotypical variability and plasticity. This study has revealed the phenotypic response of Scenedesmus ovalternus to UV exposures. The 15 min. of UV exposure cause decrease in cell width and cell length from their definite cell dimension. As the time of exposure increases the cell dimension decreases, after 90 min. of continuous UVR treatment the Scenedesmus cell length 12.2 µm and width 5.5µm were measured which extensively reduced from 16.5µm×9.5µm. These findings clearly signify the difference in Scenedesmus ovalternus morphology after the long term exposure of UVR and the mean cell length 14.7µm, cell width 7.7µm were measured with observation of S.ovalternus colonies and cells shrinkage. The number of cells per colonies was fixed during the course of experiment but the chlorophyll `a' content and cell dimension was greatly reduced.
