Synthesis and Characterization of Oxovanadium Complexes Incorporating Bidentate ligand

Two new oxovanadium(V) complexes, [VO(L1I)2(OEt)] and [VO(L2S)2(OEt)] (1-2) have been reported which are obtained from the reaction of the Schiff bases (L1IH1, L2SH1), (Where L1IH1 = isonicotinylhydrazone of benzaldehyde, L2SH1 = salicylalhydrazone of acetophenone) with VO(acac)2 / VOSO4 in 2:1 molar ratio. All the synthesized ligands and the metal complexes are successfully characterized by elemental analysis, IR, UV-vis and NMR spectroscopy. This study indicates that both the complex (1 and 2) is monomeric in solid state while complex 2 may have dimeric nature in solution

Comparison between tap water and kitchen waste water of selected sites of NIT Rourkela

Because of growing concern that constituents of drinking water may have adverse health effect, consumption of tap water has decreased. The main objective of this work is to determine and compare the concentrations of acidity, alkalinity, pH, turbidity,total Solids,chloride,DO,BOD,Ca, Mg, Cu and Fe. The average values of pH, Turbidity, DO, BOD, Total Hardness, Alkalinity, Acidity, Total solids, Chloride, Concentration of Ca, Mg, Fe and Cu are ranges between 5 to 6.62, 1 to 3 NTU, 1.19 to 8.16 mg/l, 2 to 63.5 mg/l, 26 to 472 mg/l, 10.77 to 11.22 p.p.m, 21 to 430 p.p.m, 13.6 to 162.5 mg/l, 8.7 to 15.84 mg/l, 6.38 to 8.87 mg/l, 0.8 to 2.03 mg/l, 0.263 to 0.29 mg/l, respectively

Reconceptualising Selfhood and Identity in Indian Tradition: A Philosophical Investigation

This paper presents a synoptic overview of two key philosophical concepts – self and identity - in Indian tradition. Drawing on both Indian and Western studies on the concept of self-hood and its implications for conceptualising identity, the paper reviews the contemporary scholarship on self-hood and outlines its relation to identity needs to be rethought if ethical possibilities of self-hood are to be given due consideration. This paper asks and addresses the nature and experience of the self in the Indian intellectual tradition, how representative Indian thinkers conceptualised the self, how such a conception of self-hood engages with the overall conception of Western history of self-hood and so on. The paper offers a comparative study of self-hood that not only underscores the significant points of convergence and divergence as theorised in Indian and Western philosophical traditions but also highlights how certain conceptions of self-hood and identity enable the project of the self’s ethical transformation

The exchange rate regime in Asia: From crisis to crisis.

Prior to the Asian financial crisis, most Asian exchange rates were de facto pegged to the US Dollar. In the crisis, many economies experienced a brief period of extreme flexibility. A `fear of floating' gave reduced flexibility when the crisis subsided, but flexibility after the crisis was greater than that seen prior to the crisis. Contrary to the idea of a durable Bretton Woods II arrangement, Asia then went on to slowly raise flexibility and reduce the role for the US Dollar. When the period from April 2008 to December 2009 is compared against periods of high in flexibility, from January 1991 to November 1991 and October 1995 to March 1997, the increase in flexibility is economically and statistically significant. This paper proposes a new measure of dollar pegging, the "Bretton Woods II score". We find that by this measure Asia has been slowly moving away from a Bretton Woods II arrangement.Exchange rate regime, Asia, Bretton Woods II hypothesis

A Study on Mechanical Behavior of Surface Modified Natural Fiber Based Polymer Composites

In recent years, natural fiber reinforced polymer composites have received much attention because of their many advantages such as lightweight, nonabrasive, nontoxic, low cost and biodegradable properties. A lot of research has been done all over the world on the use of natural fibers as a reinforcing material for the preparation of various types of composites. However, due to the incompatibility between fibers and polymer matrices, the tendency to form aggregates during processing and the poor resistance to moisture, reduce the use of natural fibers as reinforcements in polymers. Chemical treatments of the natural fiber can clean the fiber surface, stop the moisture absorption process, chemically modify the surface, and increase the surface roughness. To this end, in the present research work, the use of pretreated natural fibers in polymer matrix composites has been studied. Also, the effect of surface modification of natural fibers on the mechanical properties of bamboo fiber reinforced polymer composites has also been discussed. Finally, the surface morphology of the composite of fractured surface is analyzed using SEM study
