    Description / Table of Contents: Zusammenfassung Um etwas über den Einfluß der PUVA-Behandlung auf die Induktion der cellulären Immunität zu erfahren, wurden Meerschweinchen, die durch eine einmalige Injektion von Dinitrofluorbenzol (DNFB) in Freund's komplettem Adjuvans (FCA) in die Pfoten und die Nackenhaut sensibilisiert worden waren, an den Tagen 0, 2 und 5 mit 8-MOP, UVA oder 8-MOP+UVA behandelt und 14 Tage nach der Sensibilisierung mit Dinitrochlorbenzol (DNCB) getestet. Zwei Kontrollgruppen, behandelt mit oder ohne 8-MOP wurden, zugedeckt mit chirurgischen Tüchern, unter die PUVA 4000 Lampe gelegt, um den Wärmeeffekt zu prüfen. Beide Gruppen zeigten eine leicht erhöhte Kontaktüberempfindlichkeit. Keine veränderte Reaktivität wurde nach UVA allein beobachtet, während sich eine statistisch signifikant erhöhte, bzw. erniedrigte Kontaktüberempfindlichkeit nach 8-MOP allein, bzw. 8-MOP +UVA ergab.
    Notes: Summary To investigate the influence of 8-MOP and UVA on the induction of cell-mediated immunity, guinea pigs, sensitized with a single injection of dinitrofluorbenzene (DNFB) in Freund's complete adjuvant (FCA) in all footpads and the nuchal skin, were treated with 8-MOP, UVA, or 8-MOP+ UVA on days 0, 2, and 5 and tested with dinitrochlorbenzene (DNCB) on day 14 after sensitization. Two control groups, exposed in a covered condition to the PUVA 4000 lamp, to observe the heat effect, showed a slightly enhanced contact sensitivity in comparison to the only sensitized control group. No altered reactivity was observed after irradiation with longwave UV light alone, whereas a statistically significant enhanced resp. reduced contact sensitivity was obtained after the treatment with 8-MOP alone and the combined action of 8-MOP +UVA, respectively.

    A channel flow analysis for porous beds moving under high G forces (1980)

    Notes: An analysis is made of centrifugal flow of compacted porous beds through channels against high gas backpressure. One-dimensional compressible gas flow solutions are presented for concurrent and countercurrent solids/gas motion through the variable area channels. The physical process analyzed represents the flow through a newly developed centrifugal pump for feeding dry pulverized material against a pressure barrier. The objective of the analysis is to gain a basic theoretical understanding of this type of device. Good agreement is found between analytical predictions and test data obtained with an experimental pump feeding coal.

    Mass transfer and depolymerization of styrene in polystyreneThis paper was presented at the 73rd Annual Meeting of the American Institute of Chemical Engineers, Chicago, Illinois (November 20, 1980). (1981)

    Notes: This work shows how laboratory experiments may provide parameters which are useful in modeling a commercial process of polystyrene devolatilization. Such processes often occur at temperatures where depolymerization of polystyrene to monomer may be significant. Polystyrene devolatilizers function by forming thin films of the polymer, with styrene loss by flashing and diffusion and styrene generation by depolymerization. The modeling parameters of importance are: depolymerization rate constant, monomer diffusivity, and thermodynamic equilibrium polymer-vapor partition coefficient. Typical levels of styrene in polystyrene in the last stage of devolatilization are 100 to 1000 ppm. Pressures and temperatures in the devolatilizer are often less than 10 torr and greater than 200°C. For styrene-polystyrene the desired parameters have not been reported, nor apparently measured, at the concentration, pressure and temperature levels of interest.

    Solubility of isobutane and propane in polyethylene at high temperatures and low pressures (1983)

    Notes: A novel procedure was developed to measure the solubility of isobutane and propane in both low and high-density polyethylene at temperatures to 500°F (260°C) and vapor pressures from 1 to 1500 torr (33 psia). These measurements represent the first known solubility measurements at these combined extremes of pressure and temperature. Excellent agreement was found when our data were extrapolated to higher pressures and compared with data from another source. In the temperature and pressure regions of interest in this work, the linear isotherms were fit with a form of the Flory-Huggins equation. With the equation in that form we can now estimate the ratio of solubilities of two solutes in a given polymer from pure solute data only. We can also predict the absolute solubility of nonpolar solutes in polyethylene at various temperatures and pressures using only critical temperatures and acentric factors of the solutes.
