Structural, Electrostatic and Transport properties of tetracene under applied electric field using quantum chemical calculations
To understand the structural and electrical characteristics of Au and thiol substituted tetracene, a quantum chemical calculation has been carried out with Density Functional Theory (DFT) coupled with the Bader’s AIM theory. The various levels of applied electric field (0 – 0.21 VÅ-1) altered the geometrical conformation as well as the electronic energy levels of the molecule. Variations in MPA and NPA atomic charges of the molecule for the applied fields have been compared. The field polarizes the molecule and hence the dipole moment of the molecule increases from 0.0002 to 14.65 D. For the zero bias, the HOMO–LUMO gap is1.752 eV, as the field increases this gap decreases to 1.03 eV, which reveals that it exhibits charge transfer ability for the applied field.

Study on Environmental Geochemistry of Cu & Zn in Karaikal Coast
The present study was carried out in order to study about the textural characteristics of sediments, trace metal concentration (Cu, Zn), and their seasonal changes along with the influence of organic matter and physico-chemical parameter like pH, temperature, salinity and rainfall. Samplings were done at 3 different stations during 4 seasons starting from premonsoon-2009 to summer-2010. The changes in the phi mean grain size are due to selective winnowing of the finer grain size population by waves and currents acting in that environment. The sediments were well sorted to moderately well sorted in nature, skewness of the sediment samples were nearly symmetrical to coarse skewed and kurtosis ranged from mesokurtic to extremely leptokurtic in nature. The organic matter concentration range from 3.2% to 9.7% as minimum and maximum respectively. Concentration of reactive copper ranged from12.8ppm to 34.16ppm and the zinc concentration ranged from 39.3ppm to 228.2ppm.Thus in the present study the concentration of trace metals (copper & zinc), organic matter, grain size distribution and the interaction of Physico chemical parameters during different seasons were discussed.

Sustainable soil management practices and farmers livelihoods: A spatial perspective
Diverse soil management practices exist even within a narrow transect of farming areas in Nepal. This variation is principally due to location of farm households along the spatial gradient, infrastructure availability, market demands and farmers’ awareness to on-farm resource conservation. Over-exploitation of farm resources was negligible and disturbance to agro-ecology was minimal in the past couple of decades. In the last decade, however, due to a massive sprawl in the available farmlands along with a shift of subsistence farming towards market-oriented conventional approach, prime agricultural lands have been over-exploited. This led to negative repercussion on production base and farmers’ livelihoods. This paper concerns with the simulation of farm income through spatial modeling considering the strategy of sustainable soil management practices. Spatial modeling shows higher farm income gains due to intervention in rural areas (low income zone) and peri-urban areas (high income zone) with existing unsustainable soil management practices. Spatial explicit assessment shows that integration of micro-survey into spatial environment and subsequently modeling of present and future situation would add more information on the results from conventional surveys. Therefore spatial effects should be duly considered while formulating agriculture and rural development policies.

Synovial sheath hamstring (About One Case)
Synovialosarcoma is one of the most common soft tissue sarcomas. Despite its name, the synoviolosarcome does not seem to be of synovial origin, but is rather derived multipotent cells. Paradoxically, the more often it is tumors that are within distance joints. Synovialosarcoma is in order of frequency the third histological type among soft tissue sarcomas. Complete surgical removal of the tumor is the basis of traitement.la adjuvant radiotherapy for appears beneficial residual tumor. As for chemotherapy, it remains to be explored its role.

Synthesis and Characterization of Transition Metal Complexes of Substituted Furoinhydrazones
Recently, the synthesis of 2-hydroxybenzoinhydrazone, 2-hydroxybenzoinphenylhydrazone and 2-hydroxybenzoinsemicarbazone with hydrazine hydrate, phenyl hydrazine and semicarbazide hydrochloride in presence of aqueous sodium hydroxide in DMF-water (80%) medium respectively. Similarly, furoinhydrazone, furoinphenylhydrazone, furoinsemicarbazone were synthesized by the interactions of furoinbenzoin with hydrazine hydrate, phenyl hydrazine and semicarbazide hydrochloride in presence of aqueous sodium hydroxide in DMF-water (80%) medium respectively. The synthesis of 2-hydroxybenzoin and furoinbenzoin were carried out by the known literature method. The structure of all the synthesized compounds were justified on the basis of chemical characteristics, elemental and I.R. and NMR spectral analysis.Benzoin hydrazone and its metal complexes were synthesized from substituted benzoinhydrazone. They were characterized by elemental analysis and spectral analysis. The synthesized complexes were screened for antimicrobial activity. At a concentration of 1000µgm/ml. Which was serially diluted to determine their MIC value .

Synthesis and Emerging strategies of lignin degradation: A Concise Review
Lignin is a major component of wood, which is recalcitrant in nature and is not easily degraded. Its recycling is essential for the carbon cycle. Waste products from paper, pulp and wood industries impair with soil and water bodies leading to accumulation of lignin. In this review various effective physical, chemical, physico- chemical, thermo- chemicals and electrical method are discussed for lignin removal along with biological deterioration of lignin with the help of organisms (insects, fungus and bacteria). Use of microbes and insect for lignin deterioration is termed as lignin biodegradation. Lignin degradation with the help of fungi is well studied but much less studied in bacteria and insects. The present review deals with the biodegradation of lignin with the help of microbes.

The investigation of the relation between job satisfaction and emotional intelligence
The main aim of this study is analysis of job satisfaction and emotional intelligence between staffs in private banks in Kermanshah. This study is according to descriptive analysis and reaching branch and information gathering tools is questionnaire and for assessing job satisfaction we use briefed and worth 18 questionnaires and for assessing emotional intelligence we use Mayer and Salvoy 27questionaries. Sample population volume 270 subjects from staff's private banks in Kermanshah and according to sampling random way some of them had been chosen a stoical population and finally we collected 92 questions airs. For determining normality of data we use Kolmogorov -Simonov test and results of tests confirm normality of data so meaningful relationship between them had approved.
