    Membranes for measuring Low Molecular Weights by Osmotic Pressure (1967)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Membranes have recently been developed for the ultra-filtration of micro-solutes with nominal lower limits of molecular weights of 350, 1,000 and 10,000. These membranes are hydrous polymers and are described as the interaction product of polyanions and polycations. They have an ionically ...

    Measuring the Social-Care Service Needs of Impaired Elderly People in Japan (1996)

    Notes: This study aims to measure objectively and/or estimate the needs of impaired elderly persons and their families for social care services. The research was carried out in Maebashi, a medium size Japanese city. In our study, ‘impaired elderly persons’ included both physically and/or mentally impaired persons. In total, 693 impaired elderly persons and their families were classified according to 20 specific types of need: these ‘need types’ were cross-tabulated with two sets of factors: (1) Severity of impairments and (2) Difficulty of caregivers in providing the required care. A standard model of the service provision necessary for each ‘need type’ was established through group consultation with social care service professionals. Finally, the total amount of each service required in the city was calculated. Major findings are: (1) Our estimates indicate that 7.1 per cent of all persons 65 and over residing in Maebashi City were physically and/or mentally impaired to a certain degree. (2) Forty per cent of these elderly people were being cared for by caregivers who themselves had serious difficulties. (3) The demand for social care services in local Japanese cities is high. In order for this demand to be met a substantial expansion of both nursing home care and in-home care services is required.

    The fractional precipitation of soil humic acid by ammonium sulphate (1968)
    Springer
    Plant and soil 29 (1968), S. 305-316 
    Details
    ISSN: 1573-5036

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A number of fractions have been obtained from a soil humic acid by salting-out and by leaching with ammonium sulphate. The fractions obtained are characterised by infra-red and ultra-violet spectroscopy and osmometry. The fractions removed at relatively low saturation with ammonium sulphate are less highly charged and contain more aliphatic hydrocarbon groups per unit weight than the fractions precipitated at high concentrations of salt. In addition, the number average molecular weight of successive fractions precipitated with ammonium sulphate decreases significantly.
