    Combined gamma and passive X-ray fluorescent measurement of235U enrichment and U-total concentration (1991)
    Springer
    Journal of radioanalytical and nuclear chemistry 152 (1991), S. 161-173 
    Details
    ISSN: 1588-2780

    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract A new combined single step gamma-spectrometric and passive X-ray fluorescent measurement method and a corresponding procedure have been developed. Only one gamma-X-ray spectrometric measurement is required in order to determine both235U enrichment and U-total concentration of the measured sample. In this way, if the sample is homogeneous and weighted, the total quantities of U-total and235U can be determined. The main advantages of this approach over the enrichment measurement method used are: (1) the U-concentration of the measured material is determined; (2) the235U enrichment is determined more reliably and accurately. The matrix of the material, which influences the enrichment measurement, is also determined and taken into account.

    Fungal elicitor preparations and methyl jasmonate enhance rosmarinic acid accumulation in suspension cultures of Coleus blumei (1999)
    Springer
    Plant cell reports 18 (1999), S. 485-489 
    Details
    ISSN: 1432-203X
    Keywords: Key wordsColeus blumei (Lamiaceae) ; Fungal elicitor ; Methyl jasmonate ; Constitutively accumulated defense compound ; Rosmarinic acid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: bstract Suspension cultures of Coleus blumei (Lamiaceae) treated with either an elicitor preparation from the culture medium of the phytopathogenic oomycete Pythium aphanidermatum or with methyl jasmonate enhanced accumulation of rosmarinic acid approximately threefold. The specific activities of phenylalanine ammonia lyase and rosmarinic acid synthase were also enhanced after addition of the fungal elicitor. The addition of methyl jasmonate transiently increased activities of phenylalanine ammonia lyase and hydroxyphenylpyruvate reductase, whereas the activity of rosmarinic acid synthase was not stimulated and the activity of tyrosine aminotransferase was slightly and constantly enhanced. Methyl jasmonate stimulated rosmarinic acid accumulation not only when added directly to the culture medium, but also when it could reach the cells only via the gas phase.

    Primary coolant circuit characterization related to starting up the WWER-440 unit (1985)
    Springer
    Journal of radioanalytical and nuclear chemistry 88 (1985), S. 85-96 
    Details
    ISSN: 1588-2780
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Neutron activation analysis, gamma-ray spectrometry, particle sizing and photography of the corrosion products were used to qualify the constructional materials and primary coolants. The investigations related to: characterization of the construction materials of the primary circuit, circulated washing, hot conditioning, physical and energetic start up. The aim of the measurements was to study the cleanness of the primary circuit from assembling up to energetic start up and to follow closely the variation in the amount and the removing of the mechanical contaminants and corrosion products depending on the technological parameters.

    Distribution of trace and minor elements in hungarian spice paprika plants (1988)
    Springer
    Journal of radioanalytical and nuclear chemistry 122 (1988), S. 233-238 
    Details
    ISSN: 1588-2780
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Detailed investigations were carried out to study the distribution of trace and minor elements in different parts (fruit, seed and rib, peduncle, stem, leaf, root) of ripe Hungarian spice paprika plants. Two varieties of paprika plants were analyzed for their Cl, Co, Fe, K, Mg, Mn, Na, Rb, Sc, V and Zn content by non-destructive neutron activation analysis. The results showed that the iron contents of the samples were much higher than those of the other trace elements. For the trace elements Co, Fe, Mn, Sc, V and Zn a considerable enrichment was observed in the leaf, while the Rb and K, Na, Mg showed accumulation mainly in the peduncle. In the other parts (fruit, seed and rib, stem) of the paprika plants no significant enrichment of trace elements was found. Since some of the elements investigated may have been partially eluted during the cleaning of the roots with distilled water and, on the other hand, if the cleaning was not intensive enough, some soil particles could be retained on the samples, the data obtained for the roots should be considered with precaution.

    Notes: Many of the acclaimed advances in medical sciences have been possible because of the improvements in material sciences, particularly plastic. Radio frequency (RF) sealing of plastics has adopted an increasingly important role as a means of manufacturing medical devices. A high intensity radio signal is used to impart increased molecular vibration in two similar or dissimilar polymers. RF sealing is one of the methods for fabrication that allows the designer to seal or connect different types of plastics. This study addresses the effectiveness of this welding method applied to various commercially significant medical grade polymers with emphasis on PVC of varying hardness. The study compares measured weld strength and weld quality (inspected microscopically) at ambient and elevated temperatures. Also, selected samples of polymeric compounds were exposed after RF welding to gamma radiation, a method of medical device sterilization, in order to study the effects on the weld strength and color shift in the weld area. Of prime interest is the determination of optimum welding parameters for various constructions of plastic compounds.

    Notes: More and more jurisdictions generate increasingly strict air quality regulations that, almost without exception, include limitations on vinyl chloride. Processors frequently express concerns about their ability to meet environmental and occupational safety VCM limits. To address these concerns, the paper traces residual VCM levels through various stages of conversion from raw PVC resin to finished product storage. Another environmental concern often raised involves the reusability of molded or extruded vinyl devices. While plant regrind is routinely fed back into virgin production and its effect on physical properties is well known, solid waste management considerations increasingly involve postsale reuse of devices, an area not well explored. This paper looks at the reprocessing following long-time storage of devices, not only on physical performance but also on thermal and radiolytic (gamma sterilization) stability.
