The present experimental investigation was carried out in order to explore the possible thermodynamic and interactions studies of D(+) fructose with mixed solvent of aqueous alkali metal halides at different molalities and constant temperature. Experimental values of densities and ultrasonic velocities were carried out of the ternary mixture solution D(+)fructose with aqueous NaCl ,KCl , MgCl2 ...

A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch rectifier (BR). We study the configurations also by dynamic simulation based on a detailed model using a professional simulator. For the new c...

In this work is examined whether it is possible to predict solid-liquid-vapor phase equilibrium of ternary systems used in the SAS processing by the Peng-Robinson equation of state coupled with the LCVM mixing rules and the UNIFAC method for excess Gibbs free energy calculation. The enthalpy of fusion and the melting point temperature are estimated by group contribution methods. The results sho...

We consider a model for ternary polymer mixtures with biand tri-functional monomers and solvent molecules embedded on a honeycomb lattice. We first show that the grand partition function of the model polymer mixture is equivalent to the partition function of an eight-vertex model on the same lattice. This equivalence transforms the model into an Ising model in a nonzero external magnetic field....

A comparative study was established between two signal processing techniques showing the theoretical algorithm for each method and making a comparison between them to indicate the advantages and limitations. The methods under study are Numerical Differentiation (ND) and Continuous Wavelet Transform (CWT). These methods were studied as spectrophotometric resolution tools for simultaneous analysi...

Since evidence first appeared for 'detergent-resistant membranes' in the early to mid-1990s, cell biologists from a wide spectrum of biological sciences have been intrigued by the functional relevance of this indication of membrane heterogeneity, commonly referred to as 'lipid rafts'. Model membrane studies revealed that these lipid rafts are related to the more ordered liquid phase that forms ...

The crystal structure of the ternary imide Li 2Ca(NH) 2 has been determined using neutron powder diffraction data on a deuterated sample. The structure consists of infinite layers of edge-shared Ca[NH] 6 octahedra, which are separated by Li cations. The mobile Li (+) ions in such two-dimensional channels defined by Ca[NH] 6 octahedra layers are shown to have a great impact on the hydrogenation ...
