    Description: Key features of operational plans developed in a study of the Space Shuttle era life science payloads program are presented. The data describes the overall acquisition, staging, and integration of payload elements, as well as program implementation methods and mission support requirements. Five configurations were selected as representative payloads: (a) carry-on laboratories - medical emphasis experiments, (b) mini-laboratories - medical/biology experiments, (c) seven-day dedicated laboratories - medical/biology experiments, (d) 30-day dedicated laboratories - Regenerative Life Support Evaluation (RLSE) with selected life science experiments, and (e) Biomedical Experiments Scientific Satellite (BESS) - extended duration primate (Type I) and small vertebrate (Type II) missions. The recommended operational methods described in the paper are compared to the fundamental data which has been developed in the life science Spacelab Mission Simulation (SMS) test series. Areas assessed include crew training, experiment development and integration, testing, data-dissemination, organization interfaces, and principal investigator working relationships.

    Description: Preferred approaches and procedures were defined for integrating the space shuttle life sciences payload from experiment solicitation through final data dissemination at mission completion. The payloads operations plan was refined and expended to include current information. The NASA-JSC facility accommodations were assessed, and modifications recommended to improve payload processing capability. Standard format worksheets were developed to permit rapid location of experiment requirements and a Spacelab mission handbook was developed to assist potential life sciences investigators at academic, industrial, health research, and NASA centers. Practical, cost effective methods were determined for accommodating various categories of live specimens during all mission phases.

    Description: The integration facility survey effort described is structured to examine the facility resources needed to conduct life science payload (LSP) integration checkout activities at NASA-JSC. The LSP integration facility operations and functions are defined along with the LSP requirements for facility design. A description of available JSC life science facilities is presented and a comparison of accommodations versus requirements is reported.

    Description: The ground truth plan is outlined for correlative measurements to validate the Stratospheric Aerosol and Gas Experiment (SAGE) sensor data. SAGE will fly aboard the Applications Explorer Mission-B satellite scheduled for launch in early 1979 and measure stratospheric vertical profiles of aerosol, ozone, nitrogen dioxide, and molecular extinction between 79 N and 79 S. latitude. The plan gives details of the location and times for the simultaneous satellite/correlative measurements for the nominal launch time, the rationale and choice of the correlative sensors, their characteristics and expected accuracies, and the conversion of their data to extinction profiles. In addition, an overview of the SAGE expected instrument performance and data inversion results are presented. Various atmospheric models representative of stratospheric aerosols and ozone are used in the SAGE and correlative sensor analyses.

    Description: The feasibility of computerized automation of the Analytical Laboratories Section at NASA's Lewis Research Center was considered. Since that laboratory's duties are not routine, the automation goals were set with that in mind. Four instruments were selected as the most likely automation candidates: an atomic absorption spectrophotometer, an emission spectrometer, an X-ray fluorescence spectrometer, and an X-ray diffraction unit. Two options for computer automation were described: a time-shared central computer and a system with microcomputers for each instrument connected to a central computer. A third option, presented for future planning, expands the microcomputer version. Costs and benefits for each option were considered. It was concluded that the microcomputer version best fits the goals and duties of the laboratory and that such an automted system is needed to meet the laboratory's future requirements.

    Description: An optical radar for detecting targets in natural waters was built and tested in the Gulf of Mexico. The transmitter consists of a Q switched neodymium glass laser, with output amplified and doubled in KDP to 0.53 micrometer wavelength. The receiver incorporates a noval optical spatial filter to reduce the dynamic range required of the photodetector to a reasonable value. Detection of targets to a depth of 26 meters (84 feet) was achieved with a considerable sensitivity margin. The sensitivity of the radar is highly dependent on the optical attenuation coefficient. In general, measured returns fell between the values predicted on the basis of monopath and multipath attenuation. By means of simple physical arguments, a radar equation for the system was derived. To validate this theoretical model, measurements of optical attenuation and of water surface behavior were also instrumented, and some of these results are given.

    Notes: [Auszug] To characterise these factors we tested callus cultures of several plant species, and found carrot and rice most effective. Extracts of carrot cells, or carrot root, when added to LNB5 medium7 permitted the expression of nitrogenase (C2H2) activity by cowpea Rhizobium 32H1 grown in the absence of ...

    Notes: Cad, Sd(a++) or Super Sda is a rare, inherited, dominant blood group character which is of much interest, not only with regard to problems in pretransfusion tests (erythrocyte polyagglutination) but also in the field of lectin specificity. We have studied this blood group character in a British family with Eastern connections and present a brief account of its serological and clinical importance. Most persons are Sd(a+) but there is a wide distribution of antigen strength, ranging from ordinary Sd(a+) to Cad. Most persons also have weak anti-Sda in their serum; this is ordinarily of no clinical importance, but could cause problems if Cad bloods are transfused. The chief structural determinant of Cad specificity is N-acetyl-d-galactosamine in α-linked position, yet it is clearly distinguishable by use of appropriate lectins from other blood group antigens, A and Tn, which also have this acetyl-hexosamine as their chief structural determinant. A method for the rapid identification of Cad, applicable to all ABO groups, is described. The lectin of Dolichos biflorus, which is specific for N-acetyl-d-galactosamine in α-linked position, reacts strongly with A(A1), Tn and Cad cells, its action on Cad cells being much the strongest. Absorption-elution studies show that one and the same lectin reacts with both A1 and Tn cells. Absorption with Cad cells abolishes activity for A1, Tn and Cad cells; whereas absorption with A1 or Tn cells leaves activity for Cad. This does not necessarily indicate that anti-Cad is a separate component since the same result can be obtained by simply diluting the Dolichos reagent. However, eluates from Cad cells react only with Cad cells, whereas eluates from A1 or Tn cells react with A1, Tn and Cad cells.
