Phase Transformation and Volume Collapse of SmBi under High Pressure

The present study reveals the high pressure phase transition and associated volume collapse of SmBi which crystallize in NaCl (B1) structure. To achieve the goal we have used the modified three body interaction potential model (TBIPM) which is applying probably the first time for any compounds in high pressure model study. These interactions arise due to the electron shell deformation of the overlapping ions in the crystals. During phase transition there is an intermediate tetragonal phase which can be viewed as distorted CsCl (B2) structure and finally it transforms to CsCl (B2) phase. The values of phase transition pressure and associated volume collapse estimated by us are found to be well suited with experimental values. Thus our modified TBIPM is in good agreement with available measured data of SmBi. Keywords: rare-earth compounds, phase transition, van der Waal interactions

Elastic and Structural Properties of Plutonium Pnictides

The structural phase transitions of plutonium pnictides (PuAs and PuSb) have been investigated. The Extented Interaction Potential (EIP) model has been developed (including the zero point energy effect in three body interaction potential model). The phase transition pressures and associated volume collapses obtained from present model show in general in good agreement with available experimental data than others. The elastic constants and modulus of elasticity are also reported. Keywords: High pressure, Crystal structure, Elastic properties, Phase transition

Therapeutic Effect of Fenugreek Seed on the Patients Suffering from Diabetes Mellitus type II

Nowadays diabetes is the most dreadful disease for humankind in the whole world. Indians are more centrally obese at a given level of BMI compared to white Caucasians and that Indians are more insulin resistant even at lower level of BMI so they are more prone to have diabetes.. Consumption of fenu greek seed decreases the blood glucose level as its amount is inversely associated with insulin resistance. A detailed clinical examination done on selected patients. The criteria for the selection are as follows: 1.All patients are sedentary middle aged workers. 2. Patients with complications like were not included 3.Patients selected were explained the outline and aim of the study. They were advised to have fenugreek seed  in the form of powder. 4. We made 3 groups. Group A fed 5 gm, group B fed 10 gm and group C fed 15 gm of fenugreek seed . 5.Patients are recalled after 2 weeks for the investigation to know the proper effect of fenugreek seed. 6.The investigations include Anthropometric data, GTT, blood glucose, and serum lipid profile. The test applied for clinical estimation of blood glucose is GOD-POD (glucose oxidase peroxiadse) method. This study proves that consumption of fenugreek seed improves the blood glucose levels in the diabetics’ patients Keywords: diabetes, fenugreek seed , polysaccharid

Water Quality and Pollution Status of Lararpur Reservoir with Special Reference to Bacterial Contamination

Laharpur dam was constructed in the southwest of Bhopal city, M.P., India with an objective to store water for irrigational purpose. At the time of planning and construction of the reservoir it was in the outskirts of township but now, with the expansion of the city the reservoir has come well within the settlement. The developmental activities and occupancy in the area is exerting pressure on the water body. Surface water in urban water bodies almost always contains some degree of contamination. This is due to exposure to animals, humans, aquatic life, etc. In addition to this, variety of other human activities resulted in increasing the bacterial concentration of reservoir. Many of these bacteria are pathogenic and spread diseases like typhoid, paratyphoid, gastroenteritis etc. Inflow of sewage in the surface water may play an important role in the transmission of pathogenic agents discharged through feces. Some pathogenic bacteria like Actinomyces sp., Aerobacter aerogenes, A. cloacae, Micrococcus sp., Salmonella sp., Staphylococcus aureus, Bacillussp, and Shigella species indicate the higher level of fecal contamination of water. This untreated water poses a serious threat to the health of consumers and therefore, calls for urgent intervention by government.

High Pressure Study of IrN in Zinc-Blende Structure

The structural phase transition, volume collapse and second order elastic constants of 5d-transition metal mononitride (IrN) have been investigated by using interaction potential model (IPM) which consists of Coulomb interaction, three-body interaction and short range overlap repulsive interactions. The present theoretical approach has predicted pressure-volume relationship curves which shows that IrN exhibits a zinc-blend (ZB) type structure at an ambient pressure and undergoes a structural phase transition from B3 to B1 phase at pressure 72 GPa. The equation of state shows volume collapse of 9.09 %. The phase transition pressure and associated volume collapses obtained from this model show a reasonable agreement with other theoretical results. The second order elastic constants are also investigated for ZB phase. Keywords: High Pressure, Phase Transition, Transition Metal Compound

Antimycobacterial activity of econazole against multidrug-resistant strains of Mycobacterium tuberculosis

This study evaluated the antimycobacterial activity of econazole against multidrug-resistant (MDR) strains of Mycobacterium tuberculosis. The minimum inhibitory concentration (MIC90) and minimum bactericidal concentration (MBC>99.99) against MDR strains were found to be 0.120-0.125μg/mL and 0.125-0.150μg/mL, respectively, demonstrating the antimycobacterial potential of econazole
