    Dinoflagellate Crop in the North Sea: Mortality of Shags and other Sea Birds caused by Paralytic Shellfish Poison (1968)

    Notes: [Auszug] THE mortality of sea birds caused by paralytic shellfish poison resulted in 636 bodies being found on the Northumberland and north Durham coasts1. The shag (Phala-crocorax aristotelis) was by far the worst affected and some 80 per cent of the breeding population in Northumberland died. Only 17 per ...

    Mixing characteristics of turbulent water vapour jets measured using an isokinetic sampling probe (1998)
    Springer

    Notes: Abstract  Horizontal turbulent water vapour (steam) jets were discharged into ambient air from a circular convergent nozzle under unchoked/choked and saturated/superheated nozzle exit conditions, resulting in two-phase (liquid and vapour), two-fluid (air and water) condensing free jets. Flow properties and mixing characteristics have been measured with the aid of an isokinetic sampling probe arrangement. Radial and axial profiles of air and steam mass flow rates and mass fractions were measured from which entrainment, centreline decay and half-width spreading rates were calculated and compared with data from the literature. Overall, the mixing characteristics of the condensing jets are very similar to those of non-condensing jets extensively reported in the literature.

    A survey of renal function in outpatients with rheumatoid arthritis (1988)
    Springer
    Clinical rheumatology 7 (1988), S. 267-271

    Notes: Summary The acute renal side-effects of nonsteroidal anti-inflammatory drugs are well documented. These include interstitial nephritis, hyperkalaemia, renal tubular acidosis, fluid retention, hypertension and nephrotic syndrome. The long-term effects are less well known. We have carried out a cross-sectional survey of an unselected out-patient population with definite or classical rheumatoid arthritis to determine the prevalence of renal problems in this group. Thirty-four patients (20%) were shown to have an abnormality as defined by our criteria but in the majority this was transient or had been previously recognised. Thirteen patients (8%) had a persistent unexplained abnormality but only 1 had merited renal biopsy using established criteria (Patient 1). We conclude that the long-term use of NSAID's is associated with relatively few renal side-effects.

    A study of autonomous underwater vehicle hull forms using computational fluid dynamics (1997)

    Notes: Reduction of the propulsive power requirement by efficient hull form design is one of the important requirements for the successful operation of autonomous underwater vehicles (AUVs). In the absence of reliable and sufficiently accurate experimental data this will require experimental analysis of a large number of hull forms, a task which is both expensive and time-consuming. Recent developments in computational fluid dynamics (CFD) can offer a cost-effective solution to this problem. In this paper such a method is developed to simulate the flow past axisymmetric AUVs. Its application is discussed for four different hull forms. © 1997 John Wiley & Sons, Ltd.
