The interest in ionic liquids (ILs) as replacements for more hazardous solvents has been growing over the last years, especially industrial synthesis and liquid-liquid separations. Consequently, it is important to study their degree of dissociation (α), which quantifies ratio IL molecules dissociated into ions significantly influences viscosity, density, surface tension. In this work, ILs binar...

The development of a reactive distillation process for the production of n-butyl acetate by transesterification of methyl acetate with n-butanol is presented. Thermodynamic aspects of the quaternary system n-butyl acetate – n-butanol – methyl acetate – methanol are discussed and UNIQUAC interaction parameters derived using the Dortmund Data Bank (DDB) are given. The reaction kinetics of the het...

DEFINITION The extended entity-relationship (EER) model is a language for definition of structuring (and functionality) of database or information systems. It uses inductive development of structuring. Basic attributes are assigned to base data types. Complex attributes can be constructed by applying constructors such as tuple, list or set constructors to attributes that have already been const...

In dynamic analysis, frequency domain analysis can be used if the entire structure is linear. However, time history analysis is generally used if non-linear elements are present. Rayleigh damping has been widely used in time history response analysis. Many articles have reported the problems associated with this damping and suggested remedies. A basic problem is that the frequency area across w...

The competition between reptation and Rouse Dynamics is incorporated in the Rubinstein-Duke model for polymer motion by extending it with sideways motions, which cross barriers and create or annihilate hernias. Using the DensityMatrix Renormalization-Group Method as solver of the Master Equation, the renewal time and the diffusion coefficient are calculated as function of the length of the chai...

Background. In recent decades, information technology has become a vital component of various aspects of our lives. The use of information technology in different domains has made the analysis of the level of its acceptance/rejection a significant factor in organizations. Objectives. The aim of this study was to illustrate the application of the extended technology acceptance model in sports o...

In portfolio theory, it is well-known that the distributions of stock returns often have non-Gaussian characteristics. Therefore, we need non-symmetric distributions for modeling and accurate analysis of actuarial data. For this purpose and optimal portfolio selection, we use the Tail Mean-Variance (TMV) model, which focuses on the rare risks but high losses and usually happens in the tail of r...
