Department of Physics, Agra College Agra U.P India

Abstract :

The electronic, optical, electrical and transport properties of alkali halide crystals have been discussed. The various physical parameters such as ionicity, polarizability, bulk modulus, plasmon energy have been computed and compared with the reported data. A discussion based on PVV theory has been presented for the derived hompolar gap (Eh), Ionic gap (Ec), Perm gap (Ep), average gap (Eg), correlating ionicity with Ec & Eg as well as with various hyperfine interaction. The polarizability is investigated using the Cheml's relation and the investigated values are shown to be in accordance with the values from Clausius-Mossotti relation. The Phillips ionicity is evaluated and is used to determine the bulk modulus of these materials. The Philips ionicity is calculated and compared with the ionicity of the Tubbs and Pauling, models. The plasmon energy is evaluated using the static and optical dielectric. constant using Phillips and perm models.

Abstract :

 Rocks undergo many tectonic changes after they are found. These changes in the rock are brought by the agencies like high temperature, direct pressure, movement and mixing due to assimilation. Results of the effect of these agencies are in the form of solid, liquid or plastic state. The present study envisages to conduct field and laboratory test on these variety to identify them and discover the changes in the engineering and physical properties of these rocks in composition to non hybrid rock.

Abstract :

The Cumbam valley watershed, located in Uttamapalyam and a small part of Periyakulam taluk, the western corner of Teni District covers an area of about 890.97 Km2, Tamilnadu, has been selected for this study. A multivariate statistical assessment has been adapted to the classification of a large, irregular dataset of 55 subsurface water samples in pre-monsoon 2009 and analyzed for various water quality parameters such as pH, EC, TDS, Ca+2, Mg+2, Na+, K+, HCO3-, CO­3-, SO4-2 and Cl-. Hydrogeochemical data for 55 groundwater samples were subjected to Q- and R- mode factor and cluster analysis. R-mode analysis reveals the inter-relations among the variables studied and the Q-mode analysis reveals the inter-relations among the samples studied. The R-mode factor analysis shows that Mg and CI with CO3 account for most of the electrical conductivity, total dissolved solids and total hardness of the groundwater. Both Q-mode factor and Q-mode cluster analyses shows that there is an exchange between the river water and adjacent groundwater. Cluster classification map reveals that 97.79% of the study area comes under cluster I classification

Abstract :

The present work deals with the study of penetration depth as a function of temperature and various other microscopic interactions that exit in bilayer high temperature cuprate superconducting materials. For this, we consider a tight binding bilayer Hubbard Hamiltonian that includes the in-plane(within CuO2 plane) and out-of-plane interactions and employ Green's function technique to describe various correlations, important in superconductivity phase. The expressions for superconducting order parameters, carrier density and penetration depth are obtained. The numerical analysis shows that in bilayer cuprates the penetration depth depends on various in-plane and out-of-plane contributions as well as on temperature in an essential way. Finally, we have compared our theoretical results on penetration depth with that of recent experimental findings and found to be in qualitative agreement.

Abstract :

Increased environmental awareness and depletion of fossil petroleum resources are driving industry to develop alternative fuels that are environmentally more acceptable. Transesterified vegetable oil derivatives called `biodiesel' appear to be the most convenient way of utilizing bio-origin vegetable oils as substitute fuels in diesel engines. In this project esterified Nerium oil is used as an alternate fuel and the experiments were conducted at three different compression ratio (16:1,14.5:1,13:1) for studying the effect of compression ratio on performance ,emissions, noise and combustion characteristics of diesel engine with using N20 blend(20% nerium oil and 80% diesel) and N40 blend(40% nerium oil and 60% diesel) and diesel alone for comparison. It is observed from the results BTE at higher loads marginally high to that with pure diesel for compression ratio 13:1.SFC, TFC and NOISE tends to decrease with decrease of compression ratio for entire load range. HC and NOx have been reduced drastically at 14.5:1 compression ratio and CO and CO2 has been reduced drastically at 13:1 compression ratio. Combustion characteristics have been increased by using N20 at 14.5:1 & N40 at 13:1 compression ratios. Hence bio-fuels of nerium oil can replace diesel without compromise in engine performance.

Abstract :

The role of heat-loss function on the growth of molecular clouds in infinite homogenous thermally conducting viscous plasma incorporating permeability in the presence of suspended particles has been investigated. A general dispersion relation is obtained by using the normal mode analysis with the help of relevant linearized perturbation equations of the problem and a modified Jeans criterion of instability is obtained.

Abstract :

 In Chhattisgarh State, Arsenic content in soil is usually moderate to high. However, on some industrial sites like in Bhilai Steel Plant Bhilai, certain effluent discharges can lead to high concentrations of this chemical in the soil. After periods of rainfall and run-off, Arsenic can also be found in water. In this context, Indian researchers investigated the potential of contaminations to remove Arsenic from contaminated soils and waters. In addition, Electrokinetic model is developed in laboratory which has shown that, depending on soil conditions, these models are able to remove heavy metals in polluted soils by 85-90%. Overall, this research paper provides new insights into the decontamination and the bioremediation method of soils.

Abstract :

 The application of fly ash, as an adsorbent, has been investigated for the removal of Congo Red and Malachite Green dyes from aqueous solution. Fly ash, a waste by product of thermal power plant, was used as an adsorbent at different experimental conditions. Its adsorption capacity was found to be much better than other common adsorbents reported for the removal of Congo Red and Malachite Green.
