For mixtures with many components, some or most of the components are grouped into pseudo-components in order to reduce the dimensionality of the problem for phase equilibrium calculations, and therefore the computational effort. However, knowing the detailed fluid phase split may be important for a variety of applications. The detailed phase compositions resulting from a flash calculation perf...

an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundw...


 Hydrocarbon refrigerant is a type of environmentally friendly but it has disadvantages compared to halocarbon which flammable. The purpose mixing hydrocarbon refrigerants with halocarbons in the study was determine effect percentage mixture on temperature evaporator and reduce its flameability. mass mixed that loaded time used as independent variable, dependent variable. So relationship ...

A fluorocarbon and hydrocarbon organic solvent mixture is known as a temperature-induced phase-separation solution. When a mixed solution of tetradecafluorohexane as a fluorocarbon organic solvent and hexane as a hydrocarbon organic solvent (e.g., 71:29 volume ratio) was delivered in a capillary tube that was controlled at 10°C, the tube radial distribution phenomenon (TRDP) of the solvents was...

Mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of Mg2Ni and Mg(2-x)MnxNi (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. X-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

The lack of variation in antifungal drugs, and the misuse or inappropriate use usually causes resistant strains of the yeast in human’s normal flora. Unfortunately, a large number of Candida infection cases in immunosuppressed patients with insufficient treatment eventually can cause patient's death. The aim of this study was to evaluate the in vitro conventional antifungal azole compounds with...

We investigated the neural processing of binary gustatory mixtures of amino acids by the facial taste system of the channel catfish, Ictalurus punctatus. In vivo electrophysiological recordings indicated that the magnitude of both integrated and single-unit facial taste responses to binary mixtures of amino acids was greatest if the components bound to independent receptor sites. Facial taste r...
