    Notes: Absorption and translocation of 14C fosamine (ethyl hydrogen (aminocarbonyl) phosphonate) and/or fosamine metabolites were monitored in intermediately susceptible seedling black cherry (Prunus serotina Ehrh.) and resistant seedling rhododendron (Rhododendron sp.) and magnolia (Magnolia sp.). The mid two-thirds of the third leaf below the apical bud of each plant was treated with 0·5 μCi 14C fosamine (carbonyl carbon labelled). Plants were harvested 3, 7 and 14 days following treatment. In black cherry the majority of 14C absorption and translocation occurred during the second week following treatment, while magnolia and rhododendron translocated and absorbed most of the 14C within 3 days after treatment. Retention of 14C in the treated portion of the treated leaf did not differ between species. However, total translocated 14C was greatest in black cherry, less in magnolia, und minimal in rhododendron. Magnolia translocated 14C basipetally, while black cherry translocated acropetally, as well as basipetally.Absorpiion et migration de la fosamine 14C chez trois espèces de plantes ligneusesL'absorptlon et la migration de La 14C fosamine ((amino carbonyl) phosphonate d'éthyle hydrogène) et/ou de ses métabolites, ont étéétudiées chez des plantules moyennement sensibles de Prunus serotina (Ehrh.) et chez des plantules résistantes de rhododendron (Rhododendron sp.) et de magnolia (Magnolia sp). Les deux tiers moyens de la troisième feuille en-dessous du bourgeon apical de chaque plant ont été traités avec 0.5 Ci 14C de fosamine (marquée sur le carbone du carbonyl). Les plantes ont été récoltées 3, 7 et 14 jours après le traitement. Chez P. serotina, la plus grande partie de l'absorption et de la migration du 14C a eu lieu durant la deuxième semaine après le traitement, alors que chez le magnolia et le rhododendron, le maximum d'adsorption et de migration s'est situé dans les trois jours qui ont suivi le traitement. La rétention du 14C dans la partie traitée n'a pas variè d'une espèce à l'autre. Toutefois, la quantité totale de 14C qui a migré a été plus grande chez P. serotina, moindre chez le magnolia et minimaie chez le rhododendron. Chez le magnolia, la migration du 14C s'opere dans le sens basipète, alors que chez le P. serotina. elle s'effectue aussi bien dans le sens acropète que dans le sens basipète.Aufnahme- und Trunstokaiion von 14C-Fosaminc bei drei GehölzpflanzenEs wurde die Aufnahme und die Translokation von 14C Fosamine (O-Äthyl-aminocarbonylphosphonsäure) und/oder seiner Abbauprodukte bei drei Gehölzarten beobachtet. Verwendet wurden Sämlinge der Traubenkirsche (Prunus serotina Ehrh.), die eine mittlere Empfindlichkeit zeigt und Sämlinge des resistenten Rhododendron (Rhododendron sp.) und der ebenfalls resistenten Magnolie (Magnolia sp.). Die mittleren zwei Drittel des dritten Blattes unterhalb der Endknospe wurden bei jeder Pflanze mit 0.5 μCi 14C-Fosamine (markiert am Carbonylkohlenstoff) behandelt. Die Pflanzen wurden nach 3, 7 und 14 Tagen nach der Behandlung geerntet. Bei der Traubenkirsche wurde während der zweiten Woche am meisten 14C aufgenommen und transloziert, während dies bei der Magnolie und dem Rhododendron bereits innerhalb der ersten drei Tage der Fall war. Bezüglich der Retention von 14C in der behandelten Blattfläche unterschieden sich die drei Arten nicht. In der Traubenkirsche wurde aber am meisten 14C transloziert, weniger in der Magnolie und am wenigsten im Rhododendron. Die Magnolie translozierte das 14C basipetal, während die Traubenkirsche akropetal wie basipetal translozierte.

    Notes: [Auszug] We tested samples from 50 haemophiliacs from the New England Area Comprehensive Hemophilia Center in Worcester, Massachusetts; 44 of the patients had haemophilia A and 6 had haemophilia B. All haemophilia A patients had moderate or severe disease and received home infusions of commercial factor ...

    Description: We tested serum samples from 50 hemophiliacs from Sevilla, Spain, for antibody to HTLV-III by indirect membrane immunofluorescence (IMI) and radioimmunoprecipitation with SDS polyacrylamide gel electrophoresis (RIP-SDS/PAGE). All had received commercial clotting factors from the United States with the exception of one hemophiliac who had never been transfused. Thirty-four (68%) reacted with HTLV-III-infected cells (H9/HTLV-III) by both methods, but not with the uninfected line (H9). Of 41 hemophilia-A patients tested, 28 (68%) were positive, and of nine hemophilia-B patients, six (66%) were positive. The nontransfused hemophilia-B patient was negative for antibody to HTLV-III by both methods. One patient with clinical AIDS tested positive as did six of seven with chronic unexplained lymphadenopathy. The eight individuals with AIDS or lymphadenopathy all had hemophilia A. We conclude that exposure to HTLV-III is widespread among asymptomatic hemophiliacs in Spain.

    Description: An image matching system specifically designed to match dissimilar images is described. A set of blobs and ribbons is first extracted from each image, and then generalized Hough transform techniques are used to match these sets and compute the transformation that best registers the image. An example of the application of the approach to one pair of remotely sensed images is presented.

    Description: A manpower/cost estimation model is developed which is based on a detailed level of financial analysis of over 30 million raw data points which are then compacted by more than three orders of magnitude to the level at which the model is applicable. The major parameter of expenditure is manpower (specifically direct labor hours) for all spacecraft subsystem and technical support categories. The resultant model is able to provide a mean absolute error of less than fifteen percent for the eight programs comprising the model data base. The model includes cost saving inheritance factors, broken down in four levels, for estimating follow-on type programs where hardware and design inheritance are evident or expected.
