    Springer
    Computing 38 (1987), S. 299-313 
    Details
    ISSN: 1436-5057
    Keywords: 65D05 ; 41A10 ; Interpolation ; local piecewise polynomials ; ratio slope

    Topics: Computer Science
    Description / Table of Contents: Zusammenfassung Ein Satz diskreter Datenwerte über dem Intervall [a, b], der eine Funktiong (x) repräsentiert, wird stückweise durch lokal definierte kubische Polynome interpoliert. Die entstehende Interpolationsfunktion hat folgende Eigenschaften: sie ist monoton und/oder konvex und repräsentiert alle durch die Daten vorgegebenen Wendepunkte, wobei keine zusätzlichen Wendepunkte erzeugt werden. Das Approximationsverfahren wird in Form eines FORTRAN 77-Unterprogramms angegeben.
    Notes: Abstract The interpolation of a discrete set of data, on the interval [a, b], representing the functiong(x) is obtained using a local piecewise polynomial of order 3. This piecewise cubic interpolant has the following properties: monotonicity and/or convexity or turning points that are present in the data are preserved and no extraneous turning points are created. This approximation method is also presented in the form of a FORTRAN77 subroutine.

    Physiological aspects of fire fighting (1987)
    Springer
    Fire technology 23 (1987), S. 280-291 
    Details
    ISSN: 1572-8099
    Keywords: Ergonomics ; fire fighter ; physical fitness ; aerobics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Abstract The conditions and requirements of the fire fighter and the unusual demands of fire fighting activities have received increased attention since the early 1970s. Other industries usually design physical performance requirements around the capabilities of the worker, but the fire fighter must respond to the constraints and requirements of the emergency. Recent research and its relationship to a fire fighter's physical profile are described and discussed.

    Selective blockade of components of potassium activation inMyxicola axons (1987)
    Springer
    Cellular and molecular life sciences 43 (1987), S. 169-171 
    Details
    ISSN: 1420-9071
    Keywords: Potassium conductance ; Myxicola axons ; neuronal cell bodies ; multiple K+ channels
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The K+ conductance inMyxicola giant axons activates in two phases which are pharmacologically separable. The fast phase of K+ activation is specifically inhibited by 4-aminopyridine and by the substitution of D2O for H2O. We suggestMyxicola giant axons, like the amphibian node of Ranvier, may possess more than one variety of K+ channel.

    Hickory shuckworm Cydia caryana: electroantennogram and flight tunnel studies of potential sex pheromone components (1987)
    Springer

    Description / Table of Contents: Résumé Les réponses olfactives antennaires de Cydia caryana, mesurées par électroantennogrammes (EAG), aux alcools et acétates à carbones monounsaturés en positions 12 et 14, ont montré que le système conjugué de double liaison, (E)-8-, (E)-10- du dodecadien-1-ol acétate constitue un composé chimique strutural critique de la phéromone sexuelle de C. caryana. De plus, les acétates: (E)-8-dodecen-1-ol,(Z)-8-dodecen-1-ol,(Z)-9-dodecen-1-ol, et le (Z)-12-tetradecen-1-ol, se sont révélés en AEG comme des composés secondaires de la phéromone. L'étude par AEG de la relation dose-réponse a conduit à l'hypothèse de deux catégories de populations de récepteurs de phéromones. L'analyse comportementale des résponses des papillons mâles dans le tunnel de vol aux composés qui ont provoqués les plus forts AEG, on fait estimer que les acétates (E,E)-8,10-dodécadien-1-ol et (Z)-9-dodecen-1-ol ressemblent (ou sont) les constituants de la phéromone sexuelle de C. caryana; tandis que les (Z)-8-dodecen-1-ol et (E)-10-dodecen-1-ol sont, soit des paraphéromones, soit des constituants mineurs de la phéromone. La signification biologique du (Z)-12-tétradécen-1-ol a été difficile à interprêter avec les expériences en tunnel de vol.
    Notes: Abstract Electroantennogram (EAG) measurement of male Cydia caryana moth antennal olfactory response to monounsaturated 12 and 14 carbon alcohols and acetates indicated that the (E)-8-, (E)-10- conjugated double bond system of a dodecadien-1-ol acetate is a critical chemical structural component of the C. caryana sex pheromone. Additionally, EAG measurements implicated (E)-8-dodecen-1-ol acetate, (Z)-8-dodecen-1-ol acetate, (Z)-9-dodecen-1-ol acetate and (Z)-12-tetradecen-1-ol as potential minor pheromonal components. An EAG dosage-response study suggested that there were at least two heterologous populations of pheromone acceptors. Behavioral analysis of male moth response in a flight tunnel to compounds which evoked the stronger EAG responses suggested that (E,E)-8,10-dodecadien-1-ol acetate and (Z)-9-dodecen-1-ol acetate resemble or are C. caryana sex pheromonal components, while (Z)-8-dodecen-1-ol acetate and (E)-10-dodecen-1-ol acetate are either parapheromones or are minor pheromone components. Behavioral significance of (Z)-12-tetradecen-1-ol was difficult to interpret in the flight tunnel.

    Semi-invariants in surgery (1987)
    Springer
    K-Theory 1 (1987), S. 83-109 
    Details
    ISSN: 1573-0514
    Keywords: Quadratic Poincaré complex ; cobordism ; semi-invariant ; surgery
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract A semi-invariant in surgery is an invariant of a quadratic Poincaré complex which is defined in terms of a null-cobordism. We define five such gadgets: the semicharacteristic, the semitorsion, the cross semitorsion, the torsion semicharacteristic, and the cross torsion semicharacteristic. We describe applications to the evaluation of surgery obstructions, especially in the odd-dimensional case.

    Details
    ISSN: 1572-9702
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Various chemicals commonly found in food (twelve monosaccharides, nine sugar alcohols, twenty triglycerides, eleven unsaturated fatty acids and nine saturated fatty acids) were tested in different concentrations for their ability to attract and sustain feeding by the dried-fruit mite,Carpoglyphus lactis (L.). Oleic acid, α-d-glucose and some triglycerides act as phagoincitants and phagostimulants, whiled-fucose and trilaurin are phagodeterrents.

    Influence of verticillium wilt resistant and susceptible potato genotypes on populations of antagonistic rhizosphere and rhizoplane bacteria and free nitrogen fixers (1987)
    Springer
    Applied microbiology and biotechnology 26 (1987), S. 99-104 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary Verticillium wilt resistant A 66 107-51 and susceptible Russet Burbank potatoes differentially influenced populations of rhizosphere and rhizoplane bacteria. Although differences in total bacteria between the two genotypes were not significantly different, selective differences were evident. These included increases in bacteria antagonistic in vitro toward Verticillium dahliae strain RB 5, and bacteria capable of fixing nitrogen that were more commonly associated with the wilt-resistant potato. Bacteria that were antagonistic to V. dahliae were predominantly Bacillus spp. Other antagonists were species of Pseudomonas, Gluconobacter, Flavobacterium, and Streptomyces. Nitrogen-fixing bacteria were Azotobacter and Azomonas spp. The suppression of Verticillium wilt in Russet Burbank during the growing season following the planting of A 66 107-51 may, in part, be explained by the above findings.
