A detailed GIS based study on hydrochemistry of groundwater in Chinnar sub-basin of Cauvery river, Tamil Nadu, India has been carried out to assess the quality of groundwater for determining its suitability for drinking purpose. Further, the spatial variation of various groundwater quality parameters over the basin has also been studied for November
2010. Fifty seven groundwater samples were collected and analysed for pH, conductance, total dissolved solids, total hardness, calcium, magnesium, fluoride, iron, carbonate, bicarbonate, total alkalinity, chloride, sodium, potassium, sulphate and nitrate etc., The values analyzed were evaluated in detail and compared with WHO water quality standards. TDS widely varied from 301 mg/L to 1505 mg/L with an average value of 703.51 mg/L. About 87% of the samples and spatially 789.32 km2 areas are within the maximum allowable limit for drinking (1000 mg/L). Groundwater
of the basin belongs to hard to very hard water category since the total hardness (TH) exceeds the permissible limit of 500 mg/L prescribed for drinking water. Magnesium content in groundwater fifty samples out of 57 samples exceeded the maximum allowable limit of 50 mg/L. Concentration of potassium ion in groundwater ranges from 3 mg/L to 24 mg/L with an average value of 9.11 mg/L. Thirty nine samples out of 57 samples exceeded the maximum allowable limit of 10 mg/L. Fluoride is (> 1.5 mg/L) in groundwater at 5 locations, which may cause dental and skeletal fluorosis.

Reaction of glycine with phthalic anhydride formed (1,3-Dioxo- 1,3-dihydro-isoindol-2-yl) acetic acid (1) which on heating with phosphorous pentachloride under reflux afforded(1,3-Dioxo-1,3-dihydroisoindol- 2-yl)acetyl chloride (2). The compound 2 on treatment with an ice-cold solution of hydrazine dehydrate gave(1,3-Dioxo-1,3-dihydroisoindol- 2-yl)acetic acid hydrazide (3), which on reaction with carbon disulphide followed by addition of potassium hydroxide on stirring yielded potassium salt of N-2-(1.3-dioxo-1,3-dihydr-isoindole -2-yl) acetyl ]hydrazine carbodithioic acid (4). Compound 4 was used as such for further reaction, which on heating with hydrazine dehydrate resulted in the formation of 2-(4-amino-5-mercapto-4H[1,2,4]triazole -yl-methyl) isoindole-1,3-diones (5). Compounds 5 on condensation with different aromatic acids and phosphorous oxychloride furnished 2-(6-aryl [1,2,4] triazolo [3,4-b] [1,3,4] thiadiazolo-3-yl-methyl)-isoindole 1,3-diones (6). Compounds 6 were screened for their antimicrobial potentials.

Hardening in the Zinc-Beryllium-Selenide ternaries has been achieved by cationic substitution alloying. Six samples of these ternaries are prepared by varying the concentration of Be dopant 'x'. EXAFS experiments for Zn core excitations are performed on the x-ray absorption spectroscopy (XAS) beamline at SOLEIL synchrotron radiation facility located at Gif sur Yvette, France. Extraction of useful EXAFS oscillations and various computational procedures require for the ZnBeSe spectral data analysis are discussed. Our analyses indicate that the hardening increases with Be-doping. Prospects of semiconductor alloy hardening through Be doping are also discussed in detail.

Metal oxide of titanium was deposited on native Jordanian diatomaceous clay. The chemical and structural properties of the modified and the unmodified samples were characterized by XRF, XRD, SEM and FTIR techniques. The diatomaceous clay supported titanium oxide was used in preliminary experiments to study the interactions with aniline, N-methylaniline, and N,N dimethylaniline in aqueous solution .The results showed that titanium oxide interacted with diatomaceous clay and caused some structural changes. These were reflected in the surface area of the samples and their activity in the removal of aniline and its derivatives from aqueous solutions . The removal rate of aniline and its derivatives decrease with the increase of pH. Adsorption isotherms of modified diatomaceous clay indicates that aniline and its derivatives follow type 1, which is the Langmuir isotherms.

A field experiment was conducted to study the effect of fertilizers in form of nitrogen, phosphorus, potassium, biofertilizer and vermicompost along with heavy metals –Zinc, Nickel and Cadmium on pigments –Chlorophylls and Carotenoids and yield of wheat (Triticum aestivum). Four set of experiments with a control (T1), Soil with urea (250g/plot (T2), Triple super phosphate 150g/plot (T3), Potassium sulphate 100 g/plot (T4), Soil added with bio fertilizer (T5), Soil with vermicompost (T6), with ZnSO4 (T7) with NiNO3 (T8) and CdCl2 (T9) were used study the effect on pigment content & yield of wheat (Triticum aestivum). All the treatments of agrochemicals showed significantly higher chlorophyll and carotenoid content and yield in wheat crop than control.

The Gondwana rocks of Singrimari area are dominantly arenaceous lithounits. The rocks are represented by diverse lithological variations and good preservations of sedimentary structures. Seven lithounits have been identified after field and megascopic observations. The lithofacies architecture of the succession is interpreted to reconstruct the depositional environment which ranges from point bar to channel bar of braided river system. The plant fossil remains are of Glossopteris flora. Both leaf and stemparts have been discovered from the carbonaceous shale layer. From the overall characters show the similarities with Lower Gondwana rocks.

The age is suggested to be Permo-carboniferous on the basis of plant remains and lithological characters.

The present study was undertaken to work out the impact of vehicular pollution on the pigment content of four plant species, namely Cassia fistula, Eucalyptus citriodora, Ficus religiosa and Mangifera indica growing along the road side of highways at Raipur. For study, leaf samples from different sites of the above referred species were collected and analyzed for chlorophyll a, b, and carotenoids content. Leaves were sampled from all the four directions and from almost equal heights of the plants. Primary air pollutants (SO2, NOx, SPM and RSPM) were also assessed at three different study sites. It was observed that chlorophyll ‘a’ and chlorophyll ‘b’ content varied from 0.98 mg/g to 1.72 mg/g and 0.54 mg/g to 1.10 mg/g respectively at the studied sites. Carotenoid content ranged from 1.02 mg/g to 1.62 mg/g at the study sites. Results clearly indicate that the pigment content is affected & reduce with the increase in air pollution.

The purpose of this paper is to study the effect of magnetic field on oscillatory flow of blood through porous medium in a rigid tube with a mild stenosis. Here we assumed that the blood behaves as a Newtonian fluid and the maximum height of the roughness is very small compared with the radius of the unconstricted tube. The expression are given for the instantaneous flow rate, resistive impedance and wall shear stress.

A detailed ab initio analysis is carried out for the cationic substitution doped mixed alloy's theoretical EXAFS simulations. Suitable data processing codes are used for the subsequent experimental EXAFS spectral fittings. We have simulated various x-ray scattering single and multiple paths around the core atomic environ and subsequently they are compared with the spectroscopic results. As-obtained parametric values are used to find the hardening and crystalline disorders among these heavily Be doped ZnSe ternaries. The hardening phenomenon amongst the alloys are explained by using the doping related variations of the Zn-Se and Be-Se bond lengths and the presence of structural stabilities during the initial stages of alloying.

The relationship between the long-term variations of the cosmic ray intensity & Sunspot number (Solar activity) considering the different time lags has been investigated for the period 1986 to 2009. Several aspects of the long-term variations of cosmic ray intensity have been studied, adopting the K-series analysis during the ascending & descending phase of two successive sunspot solar cycles (22, 23). Correlative analysis is the basis & has been applied for several time intervals. On the overall, from the correlative analysis it has been observed that the second parts of ascending phase for sunspot cycles are more effective in cosmic ray variation. The cumulative results of these effects produce long-term trends in cosmic ray intensity
