Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...

Oral fluids are being used as an alternative matrix to urine for drug testing. Oral fluid is considered to be less invasive and much more difficult to adulterate than urine samples. Samples of oral fluid are typically screened by an ELISA immunoassay method. Those found to be positive must be further analyzed with a mass spectrometry confirmation technique. The confirmation technique must be ab...

abstract posttraumatic intravasation of fat and debris can lead to a cascade of events. hydroxyethyl starches (hes) markedly suppress neutrophil influx by decreasing pulmonary capillary permeability and facilitating tissue oxygenation by improving microcirculation. it was hypothesized that in hypoxemic femur injury patients undergoing operative stabilization, hes administration will prevent the...

Supercritical fluids (SCF) are very interesting solvents with unique properties, such as high solute diffusivities, low viscosity and density values similar to liquids. All these features can be tuned with modifications in the pressure or temperature or the addition of modifiers [1]. Supercritical CO2 (sc-CO2) is one of the most promising alternative solvents because it is cheap, abundant, non-...

Models based on the corresponding-states principle have been extensively used for several equilibrium and transport properties of different pure and mixed fluids. Some limitations, however, have been encountered with regard to its application to long chain or polar molecules. Following previous studies, where it was shown that the corresponding-states principle could be used to predict thermoph...

BACKGROUND Antifreeze proteins are found in certain fish inhabiting polar sea water. These proteins depress the freezing points of blood and body fluids below that of the surrounding sea water by binding to and inhibiting the growth of seed ice crystals. The proteins are believed to bind irreversibly to growing ice crystals in such a way as to change the curvature of the ice-water interface, le...

We present a semiempirical approach to the density functional theory of gas–liquid nucleation, in which the same experimental properties used in classical nucleation theory ~equilibrium vapor pressure, liquid density, and surface tension! are used to fit three adjustable parameters in the intermolecular potential. This approach allows direct comparison of nucleation rates with experimental data...

The basic assumptions of van der Waals theory are contained in two well-known concepts: excluded volume (repulsive forces) and a homogeneous, isotropic field potential (attractive forces). We have superimposed on these, one more well-known concept: the existence of dimers, trimers, etc., at chemical equilibrium. With reasonable simplifying assumptions, we obtain a closed-form equation of state,...

We report the first study of fingering and labyrinthine instabilities in freely suspended polar liquid-crystalline films. This phenomenon is in a way the electric analogy to the labyrinthine instability in thin films of magnetic fluids. Because of the existence of a permanent polarization in the smectic films, an external electric field is not required for the spontaneous formation of the insta...

After some post-natal cooling, a spinning, magnetized, canonical neutronstar (NS) has a core of superconducting protons, superfluid neutrons, and degenerate extreme relativistic electrons, all surrounded by a thin highly conducting solid crust. The quantum fluids are threaded by a dense array of quantized vortex-lines which can interact strongly with a denser and much less uniform one of quanti...
