The resistance of the enzyme is very high, 800 krads being necessary for a 50 per cent reduction of activity, and the enzyme is completely destroyed by 2.5 Mrad.

Nahrungsproben von Säuglings- und Kleinkinderkost aus Nordrhein-Westfalen wurden mit Hilfe der instrumentellen Neutronenaktivierungsanalyse untersucht und zeigten, daß der Selengehalt der hiesigen Gemüse und Früchte durchschnittlich etwa 5 ng/g beträgt. Nur Proben von Kartoffeln und Bananen weisen einen höheren Selengehalt auf. Bananen, importiert aus verschiedenen Gebieten der Erde, zeigen eine extrem hohe Schwankungsbreite mit Werten zwischen 4 und 164 ng Se/g. Fertiggerichte für Säuglinge und Kleinkinder haben einen der Kuhmilch vergleichbar niedrigen Selengehalt von durchschnittlich 24 ng/g. Außer Eiern enthalten nur Milchbreie und einige andere getreidehaltige Produkte mehr als 100 ng Se/g.Notes: Summary The selenium content of food exhibits great regional differences. Food samples of infants and young children from the North Rhine-Westphalia State in the Fed. Rep. of Germany were analysed by instrumental neutron activation analysis and showed that the average selenium content of local vegetable and fruit is below 5 ng/g wet weight. Only samples of potatoes and bananas exhibit higher selenium contents. The bananas, probably imported from different areas of the world, show an extremely high variance with values between 4 and 164 ng Se/g. Commercially available ready-for-use meals for infants or young children have a low Se content (median 24 ng/g) which is comparable to cow's milk. Besides eggs, cereals enriched with milk and some other cereal products contain more than 100 ng Se/g.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8838Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyElectrical Engineering, Measurement and Control TechnologyNotes: Abstract Mediated electrochemical oxidation (MEO) with Ag(n) and Co(iii) in 7 m HNO3 and 3.5 M H2SO4 has been studied. High degradation rates were found for superchlorinated organic substances such as pentachlorophenol (PCP), Lindane and polychlorinated biphenyls (PCBs) using Ag(ii) in HNO3 as mediator. An investigation on the formation kinetics of Ag(ii), Co(iii), and Ce(iv) by means of a rotating disc electrode (RDE) led to a quantitative determination of limiting currents at various mediator concentrations. Reaction rate constants of water oxidation by Ag(ii) were determined at various temperatures and compared to reaction rates of Co(iii).Type of Medium: Electronic ResourceURL: -

ISSN: 1434-601XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The theory of Dzyaloshinskii allows us to calculate the van der Waals force acting between two surfaces which are held at a distance of 104 Å and less. This calculation was based on the experimentally determined absorption data of quarz. The deflection of a thin quarz plate which was supported at one end with a vaporized bar has been measured to verify the theoretical results. Within the range of accuracy a fair agreement could be reached.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-4475Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Zusammenfassung Es wird untersucht, inwieweit es möglich ist, die spezifischen, vorwiegend hydrophilen adsorptionseigenschaften von handelsüblichem Silikagel durch nachträgliche Veränderungen der chemischen Struktur, insbesondere an der inneren Oberfläche, womöglich in organophile Eigenschaften umzuwandeln. In der Annahme, daß die an der Oberfläche des Gels befindlichen Si−OH-Gruppen für die bevorzugte Wasseradsorption verantwortlich seien, wurden diese durch Substitution mit organischen Resten entfernt. Ferner wurde Silikagel bei drei verschiedenen Temperaturen behandelt, um auch diesen Effekt auf die Adsorptionseigenschaften zu studieren. Diese “Organogele” und die thermisch behandelten Gele wurden auf ihre Adsorptionsfähigkeit für Äthylen — als Beispiel eines relativ kleinen dipollosen organischen Moleküls — und für Wasser untersucht. Außerdem wurde die Zahl der Si−OH-Gruppen quantitativ bestimmt und die Größe der Oberfläche nach der BET-Methode durch Aufnahme der Adsorptionstherme von Argon bei—183° C ermittelt. Bei den Organogelen wurde die Adsorptionsfähigkeit für Äthylen und Wasserdampf etwa gleichmäßig verkleinert, während die Oberfläche wohl kleiner wurde, quantitativ jedoch einen anderen Verlauf zeigt. Auch für die thermisch behandelten Gele nahm die Adsorptionsfähigkeit ab, und zwar um so stärker, je höher die Temperatur war, der das Gel ausgesetzt war. Die Zahl der Si−OH-Gruppen nimmt ebenfalls sowohl bei der Substitution durch organische Gruppen als auch bei der thermischen Behandlung ab, doch zeigt die Abnahme in quantitativer Hinsicht einen anderen Verlauf. Daher scheint die Ansicht, daß die Wasseradsorption mit der Zahl der OH-Gruppen zusammenhängt, nicht berechtigt. Mit Hilfe von Infrarotspektren gelang es nachzuweisen, daß bei den Organogelen die Substitution wirklich an den Si−OH-Gruppen stattgefunden hat.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-6036Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Thermal stimulated currents of undoped, of NH3 and of NiCl2 doped crystals were measured and the obtained thermograms decomposed into individual first order kinetics and space charge peaks. Details concerning the procedure of decomposition are given. The results confirm the formation of anion and cation vacancies respectively in consequence of the doping and show that the charge transport is realized in several thermal stimulated steps. Below zero centigrade it is realized most probably by a sequence of proton transfers and restricted in distance. Above this temperature the vacancies become mobile and allow a steady d.c. current. The processes are explained by a ‘catalytic’ NH 4 + Cl−⇌NH3 + HCl reaction.Type of Medium: Electronic ResourceURL: -

ISSN: 1420-9071Keywords: Morula ; blastocyst ; nuclei ; vital stain ; Hoechst 33258Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary An easy and rapid method of counting the number of cells in the preimplantation mouse embryo is described. The procedure increases the speed with which large numbers of embryos can be processed using a simple squash technique. Cell numbers are determined by exposing the embryos to the fluorescent DNA-binding dye, Hoechst 33258, removing the zona pellucida and simply squashing the embryo and counting the number of fluorescent nuclei. An increase in fluorescent intensity and maintenance of nuclear conformation of the squashed preparations are greatly improved by the use of the non-ionic detergent Triton X-100. Viability of dye-treated fertilized one-cell and blastocyst stage embryos is maintained at least up to day 13 of pregnancy following transfer of the embryos to the uteri of pseudopregnant recipients. Additional uses for this staining technique are discussed.Type of Medium: Electronic ResourceURL: -
