    A Comparison of SIR-B Directional Ocean Wave Spectra with Aircraft Scanning Radar Spectra (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-06-20
    Beschreibung: Directional ocean wave spectra derived from Shuttle Imaging Radar-B (SIR-B) L-band imagery collected off the coast of southern Chile on 11 and 12 October 1984 were compared with independent spectral estimates from two airborne scanning radars. In sea states with significant wave heights ranging from 3 to 5 meters, the SIR-B-derived spectra at 18 degrees and 25 degrees off nadir yielded reasonable estimates of wavelengths, directions, and spectral shapes for all wave systems encountered, including a purely azimuth-traveling system. A SIR-B image intensity variance spectrum containing predominantly range-traveling waves closely resembles an independent aircraft estimate of the slope variance spectrum. The prediction of a U.S. Navy global spectral ocean wave model on 11 October 1984 exhibited no significant bias in dominant wave number but contained a directional bias of about 30 degrees espect to the mean of the aircraft and spacecraft estimates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beal, R C -- Monaldo, F M -- Tilley, D G -- Irvine, D E -- Walsh, E J -- Jackson, F C -- Hancock, D W 3rd -- Hines, D E -- Swift, R N -- Gonzalez, F L -- Lyzenga, D R -- Zambresky, L F -- New York, N.Y. -- Science. 1986 Jun 20;232(4757):1531-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17773503" target="_blank"〉PubMed〈/a〉

    Effect of Heat Treatment on Meat Enhancement of Dietary Iron Bioavailability of Meat/Ferrous Sulfate and Meat/Hemoglobin Mixtures Fed to Anemic Rats (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 51 (1986), S. 0 
    Details
    ISSN: 1750-3841

    Notizen: The effect of autoclaving on meat enhancement of dietary iron bioavailability was studied. Meat was mixed with FeSO4 or hemoglobin to obtain ratios of iron from meat to iron from FeSO4 or hemoglobin of 100:0, 75:25, 50:50, 25:75, and 0:100. One-half of each mixture (except meat:FeSO4 mixture 0:100) was autoclaved for 90 min at 15 psi. The meat mixtures were lyophilized and formulated into diets to provide approximately 35 mg Fe/kg. Hemoglobin regeneration efficiency (HRE) was determined as the percent iron gained as hemoglobin relative to the iron consumed. Heat increased the HREs of meat/hemoglobin mixtures and of hemoglobin. Heat did not affect the HRE of meat or meat/ferrous sulfate mixtures. Meat did not significantly enhance the bioavailability of total dietary iron.

    Survival data for dewatered Rainbow Trout (Salmo gairdneri Rich.) eggs and alevins (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of applied ichthyology 2 (1986), S. 0 
    Details
    ISSN: 1439-0426
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie , Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Survival of four intergravel development phases of rainbow trout, Salmo gairdneri Rich., in a dewatered environment varied with stage of development, duration of exposure, and relative humidity. Egg phases were considerably more tolerant than alevin phases. Cleavage eggs tolerated dewatering for 12 consecutive days (97% survival), the maximum period tested. Embryos tolerated dewatering until they began hatching on the eight day, when mortalities sharply increased. In contrast, eleutheroembryos had only 43% survival when dewatered 6h and pre-emergent alevins had only 36% survival when dewatered 2h. A few dewatered embryos died when relative humidity was 100%, but mortality increased significantly at 90 and 80% relative humidity. Survival of alevin phases, but not egg phases, in residual, non-flowing water was limited by formation of oxygen deficits.

    Propolypeptide of von Willebrand factor circulates in blood and is identical to von Willebrand antigen II (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-05-23
    Beschreibung: The generally mild bleeding disorder of von Willebrand disease is associated with abnormalities of two distinct plasma proteins, the large multimeric von Willebrand factor (vWF), which mediates platelet adhesion, and von Willebrand antigen II (vW AgII), which is of unknown function. The two proteins were found to have a common biosynthetic origin in endothelial cells and megakaryocytes, which explains their simultaneous absence in the severe form of this hereditary disease. Shared amino acid sequences from a 100-kilodalton plasma glycoprotein and from vW AgII are identical to amino acid sequences predicted from a complementary DNA clone encoding the 5' end of vWF. In addition, these proteins have identical molecular weights and immunologic cross reactivities. Monoclonal antibodies prepared against both proteins recognize epitopes on the pro-vWF subunit and on a 100-kilodalton protein that are not present on the mature vWF subunit in endothelial cell lysates. In contrast, polyclonal antibodies against vWF recognize both pro-vWF and vWF subunits. Thus, the 100-kilodalton plasma glycoprotein and vW AgII are identical proteins and represent an extremely large propolypeptide that is first cleaved from pro-vWF during intracellular processing and then released into plasma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fay, P J -- Kawai, Y -- Wagner, D D -- Ginsburg, D -- Bonthron, D -- Ohlsson-Wilhelm, B M -- Chavin, S I -- Abraham, G N -- Handin, R I -- Orkin, S H -- HL-30616/HL/NHLBI NIH HHS/ -- HL-34050/HL/NHLBI NIH HHS/ -- HL-34787/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 23;232(4753):995-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486471" target="_blank"〉PubMed〈/a〉

    Voyager 2 radio observations of uranus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-07-04
    Beschreibung: Within distances to Uranus of about 6 x 10(6) kilometers (inbound) and 35 x 10(6) kilometers (outbound), the planetary radio astronomy experiment aboard Voyager 2 detected a wide variety of radio emissions. The emission was modulated in a period of 17.24 +/- 0.01 hours, which is identified as the rotation period of Uranus' magnetic field. Of the two poles where the axis of the off-center magnetic dipole (measured by the magnetometer experiment aboard Voyager 2) meets the planetary surface, the one closer to dipole center is now located on the nightside of the planet. The radio emission generally had maximum power and bandwidth when this pole was tipped toward the spacecraft. When the spacecraft entered the nightside hemisphere, which contains the stronger surface magnetic pole, the bandwidth increased dramatically and thereafter remained large. Dynamically evolving radio events of various kinds embedded in these emissions suggest a Uranian magnetosphere rich in magnetohydrodynamic phenomena.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warwick, J W -- Evans, D R -- Romig, J H -- Sawyer, C B -- Desch, M D -- Kaiser, M L -- Alexander, J K -- Carr, T D -- Staelin, D H -- Gulkis, S -- Poynter, R L -- Aubier, M -- Boischot, A -- Leblanc, Y -- Lecacheux, A -- Pedersen, B M -- Zarka, P -- New York, N.Y. -- Science. 1986 Jul 4;233(4759):102-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17812898" target="_blank"〉PubMed〈/a〉

    Cation-ratio and accelerator radiocarbon dating of rock varnish on mojave artifacts and landforms (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-02-21
    Beschreibung: The first accelerator radiocarbon dates of rock varnishes are reported along with potassium/argon ages of lava flows and conventional radiocarbon dates of pluvial lake shorelines, in an empirical calibration of rock varnish K(+) + Ca(2+)/Ti(4+) ratios with age in the Mojave Desert, eastern California. This calibration was used to determine the cation-ratio dates of 167 artifacts. Although cation-ratio dating is an experimental method, some dates suggest human occupation of the Mojave Desert in the late Pleistocene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorn, R I -- Bamforth, D B -- Cahill, T A -- Dohrenwend, J C -- Turrin, B D -- Donahue, D J -- Jull, A J -- Long, A -- Macko, M E -- Weil, E B -- Whitley, D S -- Zabel, T H -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):830-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17774077" target="_blank"〉PubMed〈/a〉

    Comet giacobini-zinner: plasma description (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-04-18
    Beschreibung: A strong interaction between the solar wind and comet Giacobini-Zinner was observed oh 11 September 1985 with the Los Alamos plasma electron experiment on the International Cometary Explorer (ICE) spacecraft. As ICE approached an intercept point 7800 kilometers behind the nucleus from the south and receded to the north, upstream phenomena due to the comet were observed. Periods of enhanced electron heat flux from the comet as well as almost continuous electron density fluctuations were measured. These effects are related to the strong electron heating observed in the cometary interaction region and to cometary ion pickup by the solar wind, respectively. No evidence for a conventional bow shock was found as ICE entered and exited the regions of strongest interaction of the solar wind with the cometary environment. The outer extent of this strong interaction zone was a transition region in which the solar wind plasma was heated, compressed, and slowed. Inside the inner boundary of the transition region was a sheath that enclosed a cold intermediate coma. In the transition region and sheath, small-scale enhancements in density were observed. These density spikes may be due to an instability associated with cometary ion pickup or to the passage of ICE through cometary ray structures. In the center of the cold intermediate coma a narrow, high-density core of plasma, presumably the developing plasma tail was found. In some ways this tail can be compared to the plasma sheet in Earth's magnetotail and to the current sheet in the tail at Venus. This type of configuration is expected in the double-lobe magnetic topology detected at the comet, possibly caused by the theoretically expected draping of the interplanetary magnetic field around its ionosphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bame, S J -- Anderson, R C -- Asbridge, J R -- Baker, D N -- Feldman, W C -- Fuselier, S A -- Gosling, J T -- McComas, D J -- Thomsen, M F -- Young, D T -- Zwickl, R D -- New York, N.Y. -- Science. 1986 Apr 18;232(4748):356-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17792144" target="_blank"〉PubMed〈/a〉

    Oregon subduction zone: venting, fauna, and carbonates (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-02-07
    Beschreibung: Transects of the submersible Alvin across rock outcrops in the Oregon subduction zone have furnished information on the structural and stratigraphic framework of this accretionary complex. Communities of clams and tube worms, and authigenic carbonate mineral precipitates, are associated with venting sites of cool fluids located on a fault-bend anticline at a water depth of 2036 meters. The distribution of animals and carbonates suggests up-dip migration of fluids from both shallow and deep sources along permeable strata or fault zones within these clastic deposits. Methane is enriched in the water column over one vent site, and carbonate minerals and animal tissues are highly enriched in carbon-12. The animals use methane as an energy and food source in symbiosis with microorganisms. Oxidized methane is also the carbon source for the authigenic carbonates that cement the sediments of the accretionary complex. The animal communities and carbonates observed in the Oregon subduction zone occur in strata as old as 2.0 million years and provide criteria for identifying other localities where modern and ancient accreted deposits have vented methane, hydrocarbons, and other nutrient-bearing fluids.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kulm, L D -- Suess, E -- Moore, J C -- Carson, B -- Lewis, B T -- Ritger, S D -- Kadko, D C -- Thornburg, T M -- Embley, R W -- Rugh, W D -- Massoth, G J -- Langseth, M G -- Cochrane, G R -- Scamman, R L -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):561-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17750967" target="_blank"〉PubMed〈/a〉
