Kinetic investigations in keggin-type phosphotungstic acid catalyzed oxidation of 1-Phenylethanol and p-substituted 1-Phenylethanols by N-bromophthalimide (NBP) in aqueous acetic acid medium in presence of mercuric acetate as a scavenger have been studied. Oxidation kinetics of 1-Phenylethanols by NBP in presence of PTA (Phosphotungstic acid) shows a first order dependence on NBP and fractional order on 1-Phenylethanols and PTA. The variation of ionic strength, Hg(OAC)2, H+ and phthalimide (reaction product) have no significant effect on reaction rate. Activation parameters for the reaction have been evaluated from Arrhenius plot by studying the reaction at different temperature

Polyunsaturated fatty acid (PUFA) is commonly found in plants oil. These are considered as essential fatty acid, meaning that they cannot be synthesized by the human body but are vital for normal metabolism. PUFA has been shown to lower the risk of heart attack1 and other cardiovascular diseases1. There is limited evidence that may be useful as an add on for the treatment of depression . The DHA obtained through the consumption of PUFA is vital for grey matter structure of human brain, retinal stimulation and neurotransmission2 From our present studies i.e. effect of organic manure and the bio pesticide “Azadirachtin” on the quality of Soyabean seeds, it has been observed that the percentage of PUFA in the organic soyabean seeds sample is comparatively high i.e.11.20%, 11.79%, 11.56 % during the successive years than the percentage of PUFA in the seeds obtained by the conventional method (11.14%, 11.54%, 11.28 %) during the year 2009, 2010 and 2011 successively. This shows that the organic soyabean seeds quality is quite better. Hence farming of soyabean by using bio-fertilizer and neem based bio-pesticides is preferable.
The striking feature of biopesticides is environment friendliness and easy biodegradability, thereby resulting in lower pesticide residues and largely avoiding pollution problems associated with chemical pesticides. Further, use of biopesticides as a component of Integrated Pest Management (IPM) programs can greatly decrease the use of conventional (chemical) pesticides, while achieving almost the same level of crop yield.3

The development and scope of transition metal- coordinated antibiotics have promising pharmacological applications. Metal complexes are very useful to design the slow release and long acting drug. Although most antibiotics do not need metal ions for their biological activities there are a number of antibiotics called metalloantibiotics that require metal ions to function properly, metal ions are therefore known to accelerate drug action. The present study comprises determination of stability constant and thermodynamics of interaction of antibiotics flumequine with transition metal ion Co (II). The formation of 1:1 and 1:2 metal ligand complexes are found to be formed in 50 %( v/v) methanol – water system. The stability constant values for metal-ligand system compared at three temperatures, it is found that value of stability constant decreases with increasing temperature.

Complexes of Co(II), Ni(II) & Cu(II) with 2-hydroxy – 4 – nitro acetophenone semi carbazone have been synthesized complexes were characterized by elemental analysis, magnetic and conductivity measurements electronic and IR spectral studies and thermal analysis. The ligand was found to be tridentate. The complexes of Cobalt (II) and Ni(II) was found to be hexa co-ordinated with octahedral structure where as complexes of Cu(II) was tetra co-ordinated with square planar structure.

The aim of our study is to evaluate correlation coefficients of surface tension and viscosity with specific gravity, pH and volume in calcium oxalate stone formers and controls. The study was conducted on 50 patients divided into two groups- Group I consist of 25 stone formers and Group II consists of 25 controls i.e. non stone formers. 24-hour urine is collected from each patient and control. The Correlation coefficient of surface tension with specific gravity for group-I & Group-II comes out to be -0.207 & 0.329, surface tension with pH for group-I & Group-II comes out to be 0.151 & -0.184, and surface tension with volume for group-I & Group-II comes out to be 0.158 & 0.122. The Correlation coefficient of Viscosity with specific gravity for group-I & Group-II comes out to be 0.088 & 0.385, Viscosity with pH for group-I & Group-II comes out to be 0.387 & -0.204 and Viscosity with volume for group-I & Group-
II comes out to be 0.166 & -0.202. We can conclude from the values of coefficient coefficients that there exists no correlation between various physical properties of urine studied in relation to renal stone disease.
