The emission spectra of naphthalene labeled hydrocarbons (NpHCn) and fluorocarbons (NpFCn) and anthracene labeled hydrocarbons (AnHCn) and fluorocarbons (AnFCn) in aqueous organic mixed solvents were investigated. The fluorescence spectrum of NpHC 16 in dimethyl sulfoxide-water (DMSO-H20) is dominated by excimer emission due to formation of aggregates. Addition of a fluorocarbon compound with c...

Rhizoremediation involves the breakdown of contaminants in soil resulting from microbial activity that is enhanced in the plant root zone. The objective of this study was to assess Australian native grasses for their ability to stimulate removal of aliphatic hydrocarbons from a mine site soil. Time-course pot experiments were conducted in a greenhouse with three grass species (Cymbopogon ambigu...

A droplet-based microfluidic technique for testing multiple reagent concentrations is presented. We used this experimental approach to study combined effects of gold (AuNP) and silver nanoparticles (AgNP) with the phenolic uncoupler 2,4-dinitrophenol (DNP) with respect to the growth of Escherichia coli. In order to evaluate the toxicity of binary mixtures, we first encapsulated the E. coli cell...

The phenomenological model of Khossravi and Connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. The accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (APMD). The obtained APMD for correlative and predictive studies ...

Some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. Stiripentol (STP) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. It has poor aqueous solubilityand its solubility has to be enhanced accordingly. Polyethyleneglycol 6000 (PEG-6000) iscommonly utilized as a hydrophilic...

Structural relaxation in binary hard spherical particles has been shown recently to exhibit a wealth of remarkable features when size disparity or mixture composition is varied. In this paper, we test whether or not similar dynamical phenomena occur in glassy systems composed of binary hard ellipses. We demonstrate via event-driven molecular dynamics simulation that a binary hard-ellipse mixtur...

The paper presents the analysis of the thermal efficiency of a dividing wall distillation column and the influence of the feed composition on the reduction of energy consumption compared to a classical scheme of multicomponent mixture separation. The study relays on rigorous simulations in HYSYSTM using thermodynamically equivalent schemes. A case study is presented for the separation of a hydr...

The dehydrogenation of a Jet A hydrocarbon mixture was investigated for the production of hydrogen for fuel cell applications. This process differs from steam/partial oxidation reforming of hydrocarbons in that the hydrogen produced is free of CO, and therefore can be used in low temperature fuel cells without further purification. Because of their relative importance with respect to the spectr...

In studying the relationship between a binary variable and a covariate, it is very common that the value of the binary variable is missing for some observations, and subsequently make those observations uncategorised. In this paper we show that the uncategorised data can be treated as auxiliary information as in survey sampling literature. We establish a framework of parametric and nonparametri...

In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...
