    Notes: Hydrologic investigations typically involve the collection of water level measurements at discrete points in space and time. The high cost of commercial electronic recorders can be a burden. We have developed an inexpensive (∼$200) electronic water level recorder consisting of a Motorola microcontroller, a clock, memory, pressure transducers, and associated circuitry. The instrument is powered by a 6-V battery. These devices, each capable of monitoring up to eight channels of analog input, are presently providing continuous monitoring of nested piezometers, tide gauges, and rain gauges in hydrologic studies at the Savannah River site and the North Inlet (South Carolina) Long-Term Ecological Research (LTER) site. The instruments can be custom tailored to record water levels at any specified time interval, or whenever the water level changes by a specified amount, and can store up to 32,000 water level observations. These instruments have been used to conduct slug tests and can be configured to monitor observation wells for pumping tests. Simplicity of construction and availability of components offer hydrologists an inexpensive but reliable method of water level recording. Several examples of the use of this instrumentation in diverse hydrologic settings are described.

    Effects of damp and mould in the home on respiratory health: a review of the literature (1998)

    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.

    Conducting dietary surveys in hospitals: some practical considerations (1997)
    Bingley : Emerald
    Nutrition & food science 97 (1997), S. 107-111 
    Details
    ISSN: 0034-6659

    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.
