one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

Laser irradiation parameters, especially the laser fluence and the number of pulses are very important factors affecting microstructures formation and improvement of the surface characteristics in different medical, electronic and the other industrial applications. Information about the fluence domain and the number of pulses for the formation of the structures is very important and determines ...

The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...

In order to study the effect of spot welding parameters such as welding force, welding time and welding current intensity on nugget formation and its size in resistance spot welding process of CR3 low carbon steel sheets using ANSYS commercial software package. A 2D axisymmetric electro-thermo-mechanical finite element (FE) model is developed to simulate the nugget forming process and to predic...

There is little experimental knowledge on the sequence dependent rate of hairpin formation in RNA. We have therefore designed RNA sequences that can fold into either of two mutually exclusive hairpins and have determined the ratio of folding of the two conformations, using structure probing. This folding ratio reflects their respective folding rates. Changing one of the two loop sequences from ...

A combination of borehole Stoneley waves from full waveform acoustic logs and direct shear wave logs was used to estimate formation permeability and shear wave velocity. Data sets used here were collected by ARea's array full waveform acoustic logging tool and shear wave logging tool. The Pand S-wave velocities of the formation are determined by threshold detection with cross-correlation correc...

We present a simple phenomenological model of star formation in galaxies that describes the process with a set of a few parameters. The star formation efficiency (C eff) and the fraction of gas and metals ejected in outflows (B out) are assumed to be the main drivers of star formation. The Tully-Fisher and the Faber-Jackson relations in different passbands are used as constraints in the analysi...

Surface texture of the harder mating surfaces is one of the key factors that control the coefficient of friction during sliding. In the present investigation, various kinds of surface textures were produced on the 080 M40 steel plates. For a given kind of surface texture, roughness was varied using various grits of emery papers or polishing powders. The surface textures were characterized in te...
