    Überlegungen und Hochrechnungen zur Epidemiologie des „Acquired Immunodeficiency Syndrome“ in der Bundesrepublik Deutschland (1986)

    Description / Table of Contents: Summary A computer simulation of the morbidity and mortality rates of the “Acquired Immunodeficiency Syndrome” in the Federal Republic of Germany was performed. Since sexual intercourse is the main mode of transmission, the population was divided into six groups with different sexual behaviour. In several variations of the program it is demonstrated that during the next 15 years up to 41,000 AIDS patients can be expected. The importance of female prostitutes and male bisexuals as “vectors” who may transmit the infection into exclusively heterosexual groups is shown. Using this program, the effect of prophylaxis against infection as well as of changes of sexual behaviour within the population at large can also be examined.
    Notes: Zusammenfassung Aufgeschlüsselt nach Bevölkerungskollektiven mit unterschiedlichen sexuellen Verhaltensweisen wird anhand der bisher bekannten bzw. größenordnungsmäßig abgeschätzten epidemiologischen Daten des „Acquired Immunodeficiency Syndrome“ eine Hochrechnung der Morbiditäts- und Mortalitätsziffern für die Bundesrepublik Deutschland mittels Computer-Simulation vorgenommen; danach könnten in den nächsten 15 Jahren bis ca. 41 000 Personen erkranken. Die Bedeutung der weiblichen Prostituierten und der männlichen Bisexuellen als „Vektoren“ der Infektion aus den bisherigen Risikogruppen in Bevölkerungsteile mit ausschließlich heterosexuellen Verhaltensweisen, der Einfluß infektiologischer Schutzmaßnahmen sowie der Effekt sexueller Verhaltensänderungen breiter Bevölkerungsschichten kann mit diesem Programm ebenfalls untersucht werden.

    Analyse der Reaktionsprodukte von halogenorganischen Verbindungen unter den Bedingungen des hydrierenden Abbaus (1994)

    Notes: Analysis of the Reaction Products Formed by Hydrogenating Degradation Processes of Halogen Organic CompoundsCatalytic degradation reactions of halogenated compounds are studied using a g.c.-m.s. instrument fitted with a micro reactor. Bromobenzene, chlorotoluenephenol, -naphthalene and hexachlorocyclohexane were contacted to different nickel catalysts at room temperature. After heating up to 150°C in a hydrogen stream the desorbed compounds were analyzed to obtain more information about the occuring reactions and the distribution of products. Cyclohexane was yielded as the main product of the dehalogenation and hydrogenation processes concerning substituted monoaromatic compounds mentioned above. The reaction of the chlorinated polyaromatic systems leads to decaline. However, hexachlorocyclohexane was transformed to a complex mixture of reactive small molecules as well as stable aromatic systems.

    Description / Table of Contents: Abstract На основе статических магнитных измерений было найдено, что способность к восстановлению на аморфном катализаторе NiO−Al2O3/SiO2 уменьшается в следующем порядке: бутилен-2∼водород∼изобутилен〉бутилен-1〉 пропилен∼этилен. Температуры восстановления значительно выше температур димеризации.

The reduction temperatures are significantly higher than the dimerization reaction temperatures.

    Description / Table of Contents: Thermodynamics and Structure of Molten Mixtures Alkali Halide-Alkaline Earth HalideThermodynamic quantities ai, fi, GE, and SE were calculated on the basis of vapour pressures of molten mixtures of the type alkali halide-alkaline earth halide. Negative deviations from ideality were found in all systems. The influence of cations or anions on the properties of mixtures is discussed. There is a good correlation between GE and the change of polarization energy δEp. Strong ionic interactions were found in molten mixtures, especially in the system RbBr - CaBr2. The existence of stable complex ions in melts could not be shown by Raman spectroscopy.
    Notes: Aus den Dampfdrücken der geschmolzenen Mischungen vom Typ Alkalimetallhalogenid-Erdalkalimetallhalogenid wurden die thermodynamischen Daten ai, fi, GE sowie Orientierungswerte für SE berechnet. In allen Systemen treten z. T. beträchtliche negative Abweichungen von der Idealität auf. An ausgewählten Beispielen wird der Einfluß der Kationen bzw. Anionen auf die Mischungseigenschaften diskutiert. Für die GE-Werte ergibt sich eine gute Korrelation mit der Änderung der Polarisationsenergie δEp. Ramanspektroskopische Untersuchungen konnten die Existenz stabiler komplexer Ionen nicht belegen, weisen aber besonders bei den Mischungen RbBr - CaBr2 auf starke interionische Wechselwirkungen hin.

    Description / Table of Contents: Electrical Conductivities of Molten Alkali Halide-Alkaline Earth Halide MixturesSpecific and molar electrical conductivities of molten iodide mixtures were measured. A multiple-term polynomial equation was used to describe the temperature and concentration dependence of specific electrical conductivity. Molar conductivity of molten mixtures gives a linear dependence on the kind of cations and anions.
    Notes: Von binären geschmolzenen Iodidmischungen werden die spezifischen und die molaren elektrischen Leitfähigkeiten mitgeteilt. Zur Beschreibung der Temperatur- und Konzentrationsabhängigkeit der spezifischen elektrischen Leitfähigkeit wird ein mehrkomponentiger Polynomansatz verwendet. Die molare Exzeßleitfähigkeit der Mischungen zeigt in Abhängigkeit von der Art der Kationen und Anionen einen linearen Verlauf.
