    HLA C and D antigens associated with psoriasis (1978)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 98 (1978), S. 0

    Notizen: The frequency of two newly defined HLA antigens, HLA CT7 and DMA, was found to be greatly increased in patients with psoriasis. These two antigens and those previously found to be associated with the disease, B13, BW16 and BW17, frequently occurred together. The disease may be primarily associated with HLA DMA, or with the HLA haplotypes CT7-B13/W16/W17-DMA.

    ENZYMATIC SOLUBILIZATION OF LEAF PROTEIN CONCENTRATE IN MEMBRANE REACTORS (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 43 (1978), S. 0

    Notizen: The enzymatic solubilization of an insoluble alfalfa protein fraction was studied in a batch reactor and in a continuous flow semi-batch membrane reactor. The “white” cytoplasmic protein fraction obtained by heat precipitation was solubilized using the proteolytic enzyme trypsin. Batch studies were carried out at pH 7.7 with a trypsin to substrate ratio of 2 x 10m-3 (by weight). At 27, 37 and 47°C the hydrolysis reaction was found to be first-order in substrate concentration. The activation energy was 23.25 kcal. At 47°C the conversion level was 97% after 4 hr. For the membrane reactor system, the effects of the variables pH, temperature, substrate concentration, and trypsin to substrate ratio were evaluated with the aid of factorial design methods. The optimum operating conditions for the membrane reactor studies were 47°C at pH 7.7 with a trypsin to substrate ratio of 4 x 10-3 at a 0.5% solids concentration level. The hydrolysis process was enhanced if the reactor was operated in a washout mode prior to the addition of enzyme suggesting that soluble low molecular weight inhibitors were washed out of the reactor with the permeate. 55% of the total amount of insoluble starting material appeared as products in the permeate after 4 hr of operation under the conditions stated above.

    NADP-isocitrate dehydrogenase polymorphism in the Atlantic salmon Salmo salar (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 11 (1977), S. 0 
    Details
    ISSN: 1095-8649
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Electrophoretic variation of Atlantic salmon NADP-isocitrate dehydrogenase in liver extracts of material from Ireland is interpreted in terms of two loci, IDH-A and IDH-B, coding for cytoplasmically-located isozymes. The IDH-A locus is polymorphic with qIDH-A1=0.18 and qIDH-A2=0.82. This polymorphism is of potential value for investigating the population genetics of the two races of Atlantic salmon in Ireland. An additional, monomorphic band which appears in heart extracts may be a mitochondrial enzyme coded by a third locus.

    The management of cross-disciplinary research (1984)
    Oxford, UK : Blackwell Publishing Ltd
    R & D management 14 (1984), S. 0 
    Details
    ISSN: 1467-9310

    Thema: Wirtschaftswissenschaften
    Notizen: This paper is based on a critical review of the proceedings of the Second International Conference on Interdisciplinary Research held in 1981 in Manchester, England. Two sets of issues important for the management of collaborative research are identified. One is the need to remove ambiguities from the meanings of commonly used terminology, for which more precise definitions are proposed. Cross-disciplinary is used to describe only the nature of the task; multi- and inter-disciplinary are seen as describing alternative organizational ways of executing it. Which way should be used depends objectively on the circumstances.The other set of issues is concerned with the effect institutional setting could have on the possibility of carrying out effective cross-disciplinary activity. Six different settings are identified and broad concepts of group dynamics are used to identify theoretical and practical problems and their possible solutions. The paper concludes with a survey of the practical implications for those managing cross-disciplinary research.

    Supply of organic matter to the sediment in the northern North Sea during a spring phytoplankton bloom (1984)
    Springer
    Marine biology 78 (1984), S. 315-324 
    Details
    ISSN: 1432-1793
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Strings of moored sediment traps were deployed in a 150 m water column over a period covering the growth and collapse of the spring bloom (4 April–3 June 1976) in an area of the northern North Sea. The efficiency of collection of material in the moored traps was compared to collections in free-drifting traps in the same area of deployment. The ways in which the data from the trap collections may be interpreted was considered at some length and a best estimate of the flux of organic carbon and nitrogen to the sediment was made. For the period prior to the spring bloom (4–23 April) this flux was 50 mg C m−2 d−1 (about 20% of primary production). During the bloom (24 April–19 May) it was about 185 mg C m−2 d−1 (35% of production) and during early summer (20 May–3 June) it was 115 mg C m−2 d−1, about 25% of the overlying production. The organic carbon and nitrogen content of the material collected was measured and the material was examined microscopically. There was evidence of a large settlement of diatoms immediately after the spring bloom which was reflected in changes in the C:N and C:chlorophyll ratios of the material collected. This change in biochemical composition of the material may affect its nutritional quality and have a stimulatory effect on the growth and reproduction of the animals living in the sediment.
