    Notes: Summary Air sampling of methylbromide using 900 mg HBr-treated activated charcoal tubes, followed by solvent desorption and FID or ECD chromatographic analysis, makes it possible to evaluate concentrations ranging from 0.2 ppm (1 mg×m−3) to 250 ppm (1g×m−3) at ambient temperature even with a high hygrometric level. Thermal desorption does not lead to satisfactory results.

    Description / Table of Contents: Zusammenfassung Bei 11 Patienten mit Ulcus duodeni (UD) and 5 Patienten mit einem Ulcus des Pyloruskanals (UPK) wurden vor, 1, 5 and 10 Jahre nach proximal-selektiver Vagotomie (PSV) Sekretionsbestimmungen (basale Sekretion, BAO, and Pentagastrin-stimulierte Sekretion, PAO) durchgeführt. Dabei zeigte sich sowohl bei den UD wie den UPK eine signifikante Verminderung der Sekretion nach 1 Jahr um 66% bzw. 58% fur den BAO and von 48% bzw. 62% fur den PAO. Die Säurere-duktion betrug auch nach 10 Jahren noch fiber 50% (BAO and PAO) and es zeigten sich keine signifikanten Unterschiede zwischen UD and UPK noch zwischen Rezidivfreien and Rezidiven. Die PSV führt damit zu einer erheblichen and fiber mindestens 10 Jahre stabilen Verminderung des Säureaus-stoßes des Magens.
    Notes: Summary Eleven patients with duodenal ulcers (DU) and 5 with pyloric channel ulcers (PCU) had serial acid secretion studies before as well as 1, 5 and 10 years after proximal gastric vagotomy (PGV). One year after PGV, the basal acid output (BAO) and pentagastrin-stimulated output (PAO) were reduced by 66% and 48%, respectively, in DU and 58% and 62%, respectively, in PCU. Acid output reduction was still higher than 50% for both BAO and PAO after 10 years. There appeared to be no significant differences between DU and PCU or between recurrence-free patients and those with recurrent ulcers. Thus PGV achieves a substantial reduction in acid output, which remains stable for at least 10 years.

    Ethylene oxide pollution evaluation part I: Sampling with active charcoal tubes (1986)
    Springer
    Chromatographia 21 (1986), S. 201-204

    Topics: Chemistry and Pharmacology
    Notes: Summary Air sampling of ethylene oxide on active charcoal tubes followed by GC analysis is a frequently proposed method. This paper studies just to what extent it can be used, defining its limitations (concentration range, influence of ambient temperature and relative humidity), which are seldom taken seriously into account. This method proves inadequate to determine low pollution levels, i.e. around 2 mg m−3.

    Notes: Summary A sampling method using activated charcoal, followed by percolation with ethanol and FID or ECD chromatographic analysis, depending on the concentrations to be monitored, makes it possible to evaluate concentrations of methylene chloride between 5 and 1000mg m−3, chloroform between 0.1 and 2000mg m−3, and carbon tetrachloride between 0.015 and 1000mg m−3.

    Transport processes in narrow (capillary) channels (1985)

    Notes: Rates of mass and momentum transport in narrow flow channels (gaps 0.2-0.5 mm) have been determined over a wide range of flow velocities, 220-7,700 cm/sec (Re 1,300 to 22,000). Existing correlations that apply to smooth channels of much larger hydraulic diameter were found to be valid for the narrow channels as well. However, in the turbulent regime the condition of hydraulic smoothness could be satisfied only when the walls were optically smooth. Transport rates to rough walls were also measured. The ratio of the mass transport to the momentum transport in the form of jD/(f/2) - a measure of the improved mass transfer compared to the increased pressure drop - is given for the smooth and rough-wall cells over the Re range studied.

    The effects of cure temperature on the thermomechanical properties of UV curable coatings (1989)

    Notes: A method is presented to study the mechanical behavior of soft, UV curable coating material as a function of temperature of the prepolymer at cure. For such materials, the crosslink density (hence, equilibrium modulus) is found to decrease with increasing cure temperature. The three primary coatings are: a polyurethane acrylate with a nominal equilibrium tensile modulus of 200 psi, a polyurethane acrylate with a nominal equilibrium modulus of 1200 psi, and a non-urethane acrylate with a nominal equilibrium tensile modulus of 60 psi.
