A New Numerical Method for the Analysis of Stress Concentration in Tension Specimen
Abstract: Analyzing the stress concentration in the critical region of a mixed boundary value elastic problem has always been an important area of interest in applied mechanics. In most of the cases, the problems were circumvented using a numerical solution. A numerical approach has been used to solve elastic problems of arbitrary shaped bodies subjected to mixed boundary conditions. The formulation of displacement potential function is used in finite difference method …

In vitro Demonstration of Biofilm Formation on Catheter Materials by Candida Species Isolated from Blood Stream Infections
Abstract: In recent years, a progressive increase in the frequency of nosocomial candidaemia has been observed. Candidaemia due to vascular catheters are on the rise. There are many associated risk factors such as the type of patient, catheter location, frequency of change of cannulae, duration of catheterization, etc. Candida species produce biofilms on synthetic materials, which facilitate adhesion of the organisms to devices and render them relatively refractory to medical therapy. …

Review on UV – Visible Spectroscopy and HPLC
Abstract: Like Fourier-transform infrared spectroscopy, UV-visible spectroscopy is used to determine the purity of pharmaceutical compounds. Many substances have chromospheres, which absorb certain wavelengths of ultraviolet or visible light. Using the Beer–Lambert equation, the absorption of spectra obtained from these samples at given wavelengths can be directly related to the sample concentration. Normally, UV and UV-visible spectra are recorded at high and low pH, and the results of both are compared …
