    Notes: Discharge plasmas at high pressures (up to and exceeding atmospheric pressure), where single collision conditions no longer prevail, provide a fertile environment for the experimental study of collisions and radiative processes dominated by (i) step-wise processes, i.e., the excitation of an already excited atomic/molecular state and by (ii) three-body collisions leading, for instance, to the formation of excimers. The dominance of collisional and radiative processes beyond binary collisions involving ground-state atoms and molecules in such environments allows for many interesting applications of high-pressure plasmas such as high power lasers, opening switches, novel plasma processing applications and sputtering, absorbers and reflectors for electromagnetic waves, remediation of pollutants and waste streams, and excimer lamps and other noncoherent vacuum-ultraviolet light sources. Here recent progress is summarized in the use of hollow cathode discharge devices with hole dimensions in the range 0.1–0.5 mm for the generation of vacuum-ultraviolet light. © 2002 American Institute of Physics.

    Description / Table of Contents: Abstract Н-Форма цеолита типа У модифицирована термической обработкой (450°C) трифторметаном. С помощью этого метода фтор можно вводить в цеолитную фаѕу. Однако, кристалличность и каталитическая активность (крекинг кумола) такого образца ниже, чем для исходного НУ-цеолита.
    Notes: Abstract H-form of Y-type zeolite was modified by means of thermal treatment (450 °C) with trifluoromethane. Fluorine can be introduced into the zeolite phase using this method. However, the crystallinity and catalytic activity (cumene cracking) of the resulting sample is lower than that of the initial HY-zeolite.

    Burnout conditions for flow of boiling water in vertical rod clusters (1963)
    Hoboken, NJ : Wiley-Blackwell

    Notes: This paper deals with a new concept for predicting burnout conditions for forced convection of boiling water in fuel elements of nuclear boiling reactors.The concept states the importance of considering the ratio of heated channel perimeter to total channel perimeter.The perimeter ratio concept was arrived at from an experimental study of burnout conditions in rod clusters consisting of three rods of 13 mm. outside diameter and 830 mm. heated length. Data were obtained for pressures between 2.5 and 10 kg./sq. cm., surface heat fluxes between 50 and 120 W./ sq. cm., mass flow rates between 0.03 and 0.33 kg./sec., and steam qualities between 0.01 and 0.52.The rod clearance for the experiment were 2 and 6 mm. The diameter of the channel was 41.3 mm. Additional runs were also performed after unheated displacement rods were introduced in the channel. The rod clearance in this case was 6 mm.In the ranges investigated the measured burnout steam qualities at the outlet of the channel decrease with increasing heat flux and decreasing pressure. Furthermore it has been found that the influence of rod clearance is, in the range investigated, of small significance for engineering purposes.It has also been observed that the present burnout steam quality data for the rod clusters are much lower than those earlier obtained for round ducts. This may be explained physically by means of the perimeter ratio concept.It has also been found that the surface shear stress distribution around the channel perimeter and especially the position of maximum shear stress is of great importance for predicting burnout conditions for flow in channels.Finally the new method has helped in understanding and interpreting experimental results which earlier may have seemed inconsistent.

    Description / Table of Contents: Summary At the end of the eighteenth centuryGoeze reports about the action ofVerbascum thapsus as a repellent againstMus musculus andRattus norvegicus. A revision of this information withV. thapsus, lychnitis andthapsiforme andMus musculus as test animals does not confirm his findings.
    Notes: Zusammenfassung Nach einer Mitteilung aus dem Ende des 18. Jahrhunderts sollen sich in Blüte stehende Pflanzen vonVerbascum thapsus als Mittel zur Vertreibung vonMus musculus undRattus norvegicus eignen. Eine Nachprüfung dieser Empfehlung mitV. thapsus, lychnitis undthapsiforme anMus verlief negativ.
