Absorption of pressurized methane in normal and supercooled p-xylene revealed via high-resolution neutron imaging.

Supercooling of liquids leads to peculiarities which are scarcely studied under high-pressure conditions. Here, we report the surface tension, solubility, diffusivity, and partial molar volume for normal and supercooled liquid solutions of methane with p-xylene. Liquid bodies of perdeuterated p-xylene (p-CD), and, for comparison, o-xylene (o-CD), were exposed to pressurized methane (CH, up to 101 bar) at temperatures ranging 7.

Fabrication of a PVDF membrane with tailored morphology and properties exploring and computing its ternary phase diagram for wastewater treatment and gas separation applications.

We report a simple approach for tailoring the morphology of poly(vinylidene fluoride) (PVDF) membranes fabricated using a nonsolvent induced phase separation (NIPS) method that sustains both the hydrophilic and hydrophobic properties. Various membrane structures, skin layers and whole membrane structures as well, were obtained an experimental method based on the obtained and computed ternary phase diagram. The nonsolvent interactions with polymer solution resulted in the different forms and properties of a surface layer of fabricated membranes that affected the overall transport of solvent and nonsolvent molecules inside and outside the bulk of the fabricated membranes.

One-pot neutron imaging of surface phenomena, swelling and diffusion during methane absorption in ethanol and n-decane under high pressure.

We report a powerful method for capturing the time-resolved concentration profiles, liquid swelling and surface phenomena during the absorption of methane (CH4) in still liquid ethanol (C2D6O) and n-decane (n-C10D22) and at high spatial resolution (pixel size 21.07 μm) using neutron imaging. Absorption of supercritical methane was followed at two temperatures and two pressures of methane, namely 7.

Evidence-based intravenous pain treatment with analgesic infusion regimens.

Background And Objective: To survey all bedside-prepared analgesic infusions (two or more drugs within one vehicle) at a 1000-bed general hospital. To evaluate appropriate vehicles and acceptable drug combinations in analgesic infusions with regard to evidence-based therapy.

Design: Literature review; computer simulation of pharmacokinetics with MATLAB 6.

[An epizootiologic study of an outbreak of equine influenza in the Czech Republic in the fall of 1995].

A mild outbreak of acute respiratory infection was reported in racing horses in the fall of 1995. Four studs were investigated for the sources and routes of infection. In five horses from two herds, virus isolates were obtained which, in preliminary typing experiments, were identified as the influenza A/equi 2 virus.

Development of a disease control programme based on the use of an inactivated vaccine against infectious bovine rhinotracheitis.

Studies to investigate the efficacy of an inactivated vaccine against infectious bovine rhinotracheitis (IBR) suggest that this vaccine can prevent the in utero infection of calves from experimentally infected dams. In an experimental herd the inactivated vaccine induced a humoral immune response in both seropositive and seronegative cattle and, after subsequent intratracheal infection with IBR (BHV-1) virus, prevented development of symptoms in the cows and protected their fetuses against infection. The calves were all healthy and were born at term.

[Detection of herpesvirus serum antibodies in red deer (Cervus elaphus) imported into the Czech Republic].

Antibodies reacting in the virus-neutralisation test with bovine herpesvirus (BHV-1), the causative agent of infectious bovine rhinotracheitis (IBR), were demonstrated in a herd of red deer (Cervus elaphus) imported into the Czech Republic. Sera from the same collection were later tested against a homologous virus, termed herpesvirus cervidae 1 (HVC-1), isolated from red deer in Scotland. Out of 165 imported animals, antibodies to BHV-1 were found in 68% and to HVC-1 in 71% of the animals.

The efficacy of an inactivated IBR vaccine in the prevention of intra-uterine infection and its use in a disease-control programme.

The effects of administration of an established, inactivated IBR vaccine were studied in 30 cows from two herds (one seropositive and one seronegative). All acquired immunity which, after subsequent intratracheal infection with IBR virus, prevented development of symptoms in the cows and protected their foetuses against viral infection in utero. The calves were all healthy and were born at normal term.
