    Conducting dietary surveys in hospitals: some practical considerations (1997)
    Bingley : Emerald
    Nutrition & food science 97 (1997), S. 107-111 
    Details
    ISSN: 0034-6659
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Looks mainly at issues raised during an investigation based on hospital "feeding" of Bengali and British patients in a large general hospital. Particularly considers a range of factors relating to the carrying out of such an investigation, including recruitment of patients, type of dietary survey, duration of survey and implications of the Food Safety Act. Concludes that problems relating to nutrition in hospital are complex and relate not only to the food itself but also to factors such as the delivery of the food.

    Effects of damp and mould in the home on respiratory health: a review of the literature (1998)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This review examines whether there is a direct or indirect relation between damp or mould in the home and respiratory health. Home dampness is thought to have health consequences because it has the potential to increase the proliferation of house-dust mites and moulds, both of which are allergenic. The results from the many studies conducted to investigate whether damp and mould are associated with health outcomes are diffecult to compare because the methods of measuring exposures and helth outcomes have not been standardized. However, the studies that have been conducted in children are probably the most reliable because the confounding effects of active smoking or occupational exposures are absent, and because the presence of symptoms of cough and wheeze have been consistently investigated in many studies. The increased risk of children having these symptoms if the home has damp or mould is fairly small with an odds ratio that is generally in the range 1.5–3.5, these estimates being statistically significant when the sample size has been large enough. This range is consistent with the measured effects of other environmental exposures which are considered important to helth, such as environmental tobacco smoke or outdoor air pollutants. The potential benefits or reducing mould in the home have not been investigated, and the few studies that have investigated health improvement as a result of increasing ventilation or reducing damp in order to reduce house-dust mite levels suggest that this intervention is expensive, requires a large commitment, and is unlikely to be successful in the long term. This implies that houses need to be specifically designed for primary prevention of respiratory problems associated with indoor allergen proliferation rather than using post hoc procedures to improve indoor climate and reduce allergen load as a secondary or tertiary preventive strategy.

    The controlled assembly of microcosmic communities: the selective extinction hypothesis (1986)
    Springer
    Oecologia 71 (1986), S. 12-17 
    Details
    ISSN: 1432-1939
    Keywords: MacArthur ; Wilson ; Equilibrium model ; Community assembly ; Extinction ; Colonization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Forty communities were assembled through the controlled inoculation of algae, protozoans and a rotifer according to either of 2 distinct introduction schedules. These introduction schedules were constructed such that species reinvaded on average either every 6 or 8 w. Ten of the 20 beakers experiencing each invasion schedule contained 300 ml of media; the remaining beakers in each invasion category contained 100 ml of media. Species richness consistently increased throughout the initial 4 w and 7 w of the experiment for the low and high invasion rate beakers, respectively. The numbers of species in the low rate beakers were uncorrelated with time during the last half of the experiment; however, species richness gradually declined during this period in the high rate beakers. The extinction rate is shown to be disproportionately higher for large organisms in the small microcosms. Such “selective extinction” is consistent with the MacArthur-Wilson equilibrium model.

    Effects of geometry on the intensity of transmitted longitudinal waves (1989)
    Springer
    Experimental mechanics 29 (1989), S. 95-100 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper presents a method for determining the effects of geometry on the intensity distributions of ultrasonic longitudinal plane wave fronts (plane waves is assumed) transmitted through a specimen with geometric deformation. Its feasibility is demonstrated with the aid of a microcomputer-based scanning and data-acquisition system.
