Direct Liquid Extraction and Ionization Techniques for Understanding Multimolecular Environment in Biological Systems

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems

The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...

Direct ionization of biological tissue for mass spectrometric analysis.

Analysis of biological tissue at a molecular level is of great importance in biological, medical and clinical studies. In this manuscript, we report that both plant and animal tissues can be directly ionized and analyzed by mass spectrometry under ambient conditions. By adding some solvents and applying a high voltage, spray ionization can be induced at the tip of biological tissue and a mass s...

Framework Environment for Understanding Object Oriented Techniques

Source code analysis does not provide enough information for the program understanding activities. Understanding object oriented software systems during software maintenance are difficult and take a considerable amount of time and cost. In software maintenance perspective reverse engineering process extracts information to provide visibility of the object oriented components and relations in th...
