The presence of both critical and azeotropic states in the vapor-liquid equilibria (VLE) is a very important issue chemical refrigeration engineering. knowledge phase behavior (subcritical phase/supercritical phase) refrigerant allows designing optimizing industrials processes. However, it rare to find data for this information, which poses great challenge researchers develop predictive correla...

AIM To determine specific volumetric laser endomicroscopy (VLE) imaging features associated with neoplasia at the gastroesophageal junction (GEJ) and gastric cardia. METHODS During esophagogastroduodenoscopy for patients with known or suspected Barrett's esophagus, VLE was performed before biopsies were taken at endoscopists' discretion. The gastric cardia was examined on VLE scan from the GE...

The surface tension of oxygen and nitrogen was calculated using molecular dynamics simulation. Due to the inhomogeneity of the system, the long range correction approach of Janeček [1] was used. The results regarding the temperature dependence of the surface tension were compared to simulation data by Neyt et al. [2] and experimental data. Because of simpler statistical analogs of certain therm...

Communication is one of the main elements in the educational process and the non-verbal communication including eye blink, which is one of the key non-verbal method, owns the highest portion of the communication. The objective of this paper is to evaluate the role of eye blink in the Virtual Learning Environment (VLE). The eye blink is introduced in the VLE and the role of the eye blinking in t...

5 Germany 6 In a recent article, Zhang and Duan [1] presented a new potential model 7 for carbon dioxide (CO 2). It consists of three Lennard-Jones (LJ) sites to 8 account for repulsion and dispersion and three distributed partial charges to 9 describe the quadrupolar interaction. The molecular model is rigid and ro-10 tationally symmetric around the molecular axis. In that work [1], simulation...

traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. to design a membrane process for olefin-paraffin separation, equilibriu...

Guanidine hydrochloride has been widely used in the initial recovery steps of active protein from the inclusion bodies in aqueous two-phase system (ATPS). The knowledge of the guanidine hydrochloride effects on the liquid-liquid equilibrium (LLE) phase diagram behavior is still inadequate and no comprehensive theory exists for the prediction of the experimental trends. Therefore the effect the ...

Abstract In recent years, many compounds have been proposed as additives to conventional working fluids improve the performance of absorption refrigeration system. The main aim this research is show influence ionic liquid based on thermodynamic and physicochemical properties {LiBr + water} solutions. following additives: 3-(1-methyl-morpholinium)propane-1-sulfonate, N,N -di(2-hydroxyethyl)- -di...
