    Laser Ar-39-Ar-40 study of Apollo 17 basalts (1977)
    In:  Other Sources

    Publication Date: 2019-07-13
    Description: Three Apollo 17 basalts were studied by the laser Ar-39-Ar-40 method. The 70215 basalt has a normal well-behaved Ar-39-Ar-40 release pattern; the 70017 basalt has a disturbed release pattern which indicates a limited intermediate maximum age followed by a broad low-age region; and the 75035 basalt has a pattern initially similar to 70017 that is followed by a high-temperature maximum age. The laser study shows that all mineral systems in 70215 have small and uniform temperature losses, while the laser-determined ages for 70017 and 75035 are, apparently, primarily controlled by the minerals containing mesostasis inclusions. It is possible that the drop in ages observed by the conventional Ar-39-Ar-40 method was due not only to recoil of Ar-39 during neutron irradiation but also to gas loss from some minerals. It is suggested that the plagioclases are the best minerals to use for a reliable age.

    Laser /39/Ar-/40/Ar dating of two clasts from consortium breccia 73215 (1978)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: A laser Ar-39-Ar-40 study of the components of an ANT-suite anorthositic gabbro and a black aphanite from a consortium breccia is reported. A wide range of K-Ar ages is found for the plagioclase in the anorthositic gabbro; at the centers of the largest grains is material showing the greatest age (older than 4.11 billion years) while the youngest material (3.81-3.88 billion years) is found near the grain margins. Partial outgassing of the clasts upon incorporation into the breccia could account for the age patterns. The black aphanite clast appears to be cogenetic with the aphanite that forms the breccia matrix. The time of crystallization of a lunar granite has also been measured by the laser technique.

    Laser probe /Ar-39/-/Ar-40/ dating of materials from consortium breccia 73215 (1977)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The unique capacity of the laser-probe (Ar-39)-(Ar-40) method to determine ages of constituents in a rock sample which are only of the order of 100 microns apart has been applied to measure ages of the different constituents of consortium breccia 73215. Evidence is given that the age of the melt-derived ground mass, 4.01 + or - 0.05 billion years, has no chronological significance. Instead, the best estimate for the age of the breccia-forming event, about 3.90 billion years, comes from the study of two clasts only a few hundred micrometers in size. The interpretation of this age as the age of the breccia-forming event is also supported by the studies of other consortium members and suggests a reinterpretation of the ages of most of the other Apollo 17 highland breccias.

    Function and regulation of cytochrome P-450 in alkane-assimilating yeast (1987)

    Notes: Abstract A method for selective and reversible inhibition of the alkane hydroxylating cytochrome P-450 in growing yeast cells was developed. Using low concentrations of carbon monoxide in a specially adapted small-scale fermentor system a complete inhibition of the first step of alkane degradation was obtained, obviously without influencing further metabolic steps. Thus, fatty alcohols which were shown to be the immediate products of the cytochrome P-450 catalyzed reaction were utilized with unchanged rates by yeast cultures blocked with carbon monoxide in alkane degradation. Moreover, significant differences were found in the pO2-dependencies of utilization of n-alkanes, fatty alcohols and further intermediates. It was concluded, that the alkane hydroxylating cytochrome P-450 system is distinguished by the lowest oxygen affinity among the oxygen-activating enzyme systems involved in alkane assimilation.

    Topics: Biology
    Notes: Abstract Transition of n-hexadecane utilizing cultures of Candida maltosa to oxygen-limited growth caused an up to 6-fold increase of the cellular cytochrome P-450 content. Enhanced cytochrome P-450 formation required protein de novo synthesis and was not due to a change of the apo/holo-enzyme ratio as demonstrated by cycloheximide inhibition and immunological quantitation. The effect of low oxygen concentration (pO2=3–5%) was simulated by selective inhibition of alkane hydroxylation with carbon monoxide (at a pO2 of 70–75%). Enhanced cytochrome P-450 formation occurred even when a constant growth rate was maintained through utilization of a second non-repressive growth substrate. However, the presence of n-alkanes was an essential precondition. It was concluded, that the cytochrome P-450 formation was mainly regulated by the intracellular inducer concentration which depends on the relative rates of alkane transport into the cell and the actual alkane hydroxylating activity of the enzyme system.

    Description / Table of Contents: Additionspolymere aus Bisphenol-A und Epichlorhydrin lassen sich mit Arylacryloylchloriden verestern. Die gebildeten Photoresists können mit UV-Licht (λ ≥ 280 nm) gehärtet werden. Aus FT-IR Messungen ergibt sich, daß die Netzwerkbildungsreaktion einem Zeitgesetz zweiter Ordnung gehorcht. DSC- und TGA-Messungen wurden durchgeführt. Die photovernetzten Polymeren weisen Glastemperaturen bis zu 171 °C auf und sind bis mindestens 350 °C thermisch stabil. Spektroskopische Daten werden aufgeführt.
    Notes: Addition polymers of bisphenol-A and epichlorohydrin can easily be esterified with aryl acryloyl chlorides to yield photosensitive polymers. The photoresists are curable with UV-irradiation (λ ≥ 280 nm). FT-IR measurements indicate that the network formation fonforms to second order kinetics. DSC and TGA measurements were carried out. The glass transition temperature of irradiated material is up to 171oC; the material is thermally stable up to 350oC. Spectral data are given.
