    Superior free-standing meshes for use as infrared Fabry–Perot elements made with a new photolithographic technique (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notizen: A photolithographic technique for fabrication of very smooth and highly uniform metallic, free-standing, inductive meshes, is described. The fabrication process was developed in order to produce highly reflective, low-loss Fabry–Perot étalon elements for use in the infrared spectral region. The measured rms smoothness of the grids is typically ≤30 A(ring). Because of their nickel core, the mechanical strength of the grids is such that they can be easily stretched flat on stainless-steel rings.

    The role of fish studies in estuarine pollution assessment (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 33 (1988), S. 0 
    Details
    ISSN: 1095-8649
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: The environmental quality objective and standards (EQO/EQS) approach to controlling and assessing estuarine pollution is described together with details of the information necessary to assess the health of the fish populations and determine whether the EQO/EQS are being met in an estuary. These concepts are illustrated by examples from the Forth estuary, Scotland, involving studies of the ecology, pathology, biochemistry and contaminant bioaccumulation of fish in relation to the benthos, water quality and anthropogenic influences.

    SHORT COMMUNICATION: EFFECTS OF VASOACTIVE INTESTINAL POLYPEPTIDE INFUSIONS ON RENAL FUNCTION IN PATIENTS WITH LIVER DISEASE (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental pharmacology and physiology 15 (1988), S. 0

    Thema: Medizin
    Notizen: 1. The effect of intravenous vasoactive intestinal peptide (VIP, 6 pmol/kg per min) on renal function in six patients with cirrhosis of the liver was examined.2. VIP caused generalized vasodilation and increased plasma renin activity, but diminished the glomerular filtration rate by about one third.3. The excretion of water, sodium, potassium and calcium also fell significantly.4. These results differ from our findings in normal man in whom VIP diminished water and electrolyte secretion largely by increasing tubular reabsorption.5. It is concluded that the elevated VIP levels present in patients with severe liver disease may affect renal function, but that the presence of liver disease may affect renal responses to VIP.

    Notizen: [Auszug] SIR-Hansson1 speculates that if the defect in the control of apical membrane Cl" channels in cystic fibrosis (CF) extends to the intestine, a resistance to bacterial toxin-mediated diarrhoea may confer a selective advantage to carriers heterozygous for the CF gene.

    Assortative mating for IQ and personality due to propinquity and personal preference (1988)

    Notizen: Abstract The role of personal preference as an active process in mate selection is contrasted with the more passive results of limitations of available mates due to social, educational, and geographical propinquity. The role of personal preference estimated after removing the effects of variables representing propinquity was still significant for IQ and Eysenck's extraversion-introversion and inconsistency (lie) scales, even though small.

    Bovine and human pineal glands contain substantial quantities of endothelial cell stimulating angiogenic factor (1988)
    Springer
    Journal of neural transmission 71 (1988), S. 79-84

    ISSN: 1435-1463
    Schlagwort(e): Pineal gland ; angiogenesis ; neovascularization

    Thema: Medizin
    Notizen: Summary Using a quantitative assay the amount of a low Mr endothelial cell stimulating angiogenesis factor (ESAF) has been determined in human pineal glands and bovine brain, retina, pineal gland, liver and kidney. Pineal glands contain approximately ten times as much ESAF as the retina or grey and white matter from the cerebral cortex and a hundred times as much as highly vascular tissues such as liver and kidney. The relevance of these findings to the highly vascular nature of the pineal gland is discussed.

    Interferometric-fiber-optic strain sensor (1988)
    Springer
    Experimental mechanics 28 (1988), S. 170-176 
    Details
    ISSN: 1741-2765

    Thema: Maschinenbau
    Notizen: Abstract An interferometric-fiber-optic sensor and an efficient fringe-detection scheme are described. The fiberoptic interferometer consists of two fibers; they are labeled the reference fiber and the sensing fiber. The reference fiber is arranged in a circular pattern, whereas the sensing fiber is arranged in an ‘S’ pattern. These fibers are exposed to the same strain field and each experiences a strain-induced phase shift. A difference in the phase shift between the two fibers indicates a change in strain. The strain-induced phase difference causes the interferometrically produced fringes to shift spatially. Analysis shows that the number of fringes passing an arbitrary point on a screen (the detection point) is linearly related to the strain in the fiber. In this analysis, the strain sensor is assumed to be perfectly bonded so that the fibers experience the same strain field as the specimen. It is further assumed that the sensor covers a sufficiently small area so that the strain can be considered constant over the entire strain sensor. Also, the phase change produced by transverse strain components (with respect to the fiber) induced by the specimen is assumed negligible compared to the phase changes attributable to the axial strain components. A cantilever beam was used as a specimen. Experimentally determined strains correlated well with the strains predicted by beam theory. The fringe-detection scheme described is a high-speed fringe counter. The speed of this counter is necessary to detect vibrational phase noise which is invisible to the human eye. Two photodiodes detect the fringes, and a logic circuit counts the fringe shifts, both strain and noise induced. Since noise is random in nature, it can be averaged out. This fringe detector exhibits good sensitivity and is the key to moving the sensor from the laboratory to the field.
