    15-cm hybrid ion diode on PBFA-I (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 62 (1987), S. 3522-3534 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Diode experiments on the PBFA-I pulser using a magnetically insulated ion diode are described. The insulating magnetic field is supplied by self-field due to the ion current plus the field generated by a series field coil. In the experiments described here, the diode operated at the 10-TW, 2.5-MV level with over 300 kJ going to the diode on many shots. The operation of the diode, the dielectric anode, and the proton beam focusing are described.

    Notes: [Auszug] It was found that the spring stimulus depended on the simultaneous presence of two substances, of which the first proved to be calcium (Ca++), occurring in amounts sufficient to give a level of approximately 5 x 10-* M in a medium containing 5 g/1. crude glucose. Calcium was already known to ...

    Leaf development and phloem transport in Cucurbita pepo: Maturation of the minor veins (1976)
    Springer
    Planta 129 (1976), S. 265-269 
    Details
    ISSN: 1432-2048
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Young leaves of Cucurbita pepo L. were examined by whole-leaf autoradiography and serial paradermal sections were examined by light microscopy to determine whether commencement of sugar export depends upon the minor vein phloem achieving structural maturity. Maturation of these veins develops progressively from the largest toward the smallest elements with the minor veins in the distal region of the leaf maturing before those in the proximal region. Commencement of sugar export is coincident with maturation of the abaxial phloem of the minor veins delimiting the areoles. The abaxial phloem elements of the larger minor veins, which are probably capable of vein loading too but border only relatively few areoles, mature before export starts. The adaxial phloem surrounding the areoles and the xylem elements, mature in advance of the abaxial phloem and well before the beginning of sugar export. It is therefore considered unlikely that structural development alone directly governs the initiation of export. The results suggest that some other rate controlling step is involved.

    Plant regeneration from stem cortex expiant and protoplast cultures of Brassica juncea (mustard) (1992)
    Springer
    Plant cell reports 11 (1992), S. 614-617 
    Details
    ISSN: 1432-203X
    Keywords: Brassica juncea ; Expiants ; Protoplasts ; Regeneration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Plant regeneration from stem cortex explants of 13 genotypes of Brassica juncea was assessed. Regeneration was strongly affected by genotype, as up to 50.6 shoots were produced per 100 calli of the most responsive line (Blaze), whereas no shoots were obtained from less responsive lines (Zeml, Vniimk351). Blaze was chosen for B. juncea stem cortex protoplast isolation. After one week of culture, 11–14% of the cells had divided, and about 0.002% produced 1–2 mm colonies within 6 weeks. Up to 7% of these colonies gave rise to shoots upon transfer to plant regeneration medium.

    Leaf development and phloem transport in Cucurbita pepo: Carbon economy (1975)
    Springer
    Planta 123 (1975), S. 53-62 
    Details
    ISSN: 1432-2048
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Net photosynthesis, dark respiration and growth for leaf 5 of Cucurbita pepo L. plants grown under controlled conditions were measured and the data used for an assessment of the changes in carbon balance during growth of the leaf through expansion to maturity. The blade is first capable of net CO2 fixation when ca. 8% expanded but the initial rapid growth during this period is sustained almost entirely through imported nutrients. When the growth rate starts to decline rapidly the net photosynthetic capacity of the blade begins to increase. This increase is accompanied by an expansion of the intercellular spaces and by decreasing dark respiration measured at night and in dark periods during the day. The blade becomes completely independent of phloem imported nutrients and begins to export excess photosynthate when the phase of rapid decrease in relative growth rate is almost complete at about 45% expansion. Maximum net photosynthesis of ca. 11 mg CO2 h-1 dm-2 is achieved at 70% expansion. The first detectable synthesis of the transport sugars stachyose and raffinose in the blade coincides with the beginning of intralaminar phloem transport from the tip to the base of the leaf. The synthesis of sucrose, the other major transport sugar, is detectable at all stages of leaf development.

    Leaf development and phloem transport in Cucurbita pepo: Transition from import to export (1973)
    Springer

    Topics: Biology
    Notes: Summary The capacity of a growing leaf blade of Cucurbita pepo L. to import 14C-labelled photoassimilate is lost in a basipetal direction. Import into the lamina tip stops when the blade is 10% expanded. Development of the leaf progresses linearly with time and the lamina base stops importing when the blade is 45% expanded. Export capacity also develops basipetally and follows immediately the loss of import capacity, at least in the lamina base. The small amount of material initially exported from the leaf tip is redistributed to the still-importing leaf base, delaying export from the lamina until the blade is 35% expanded. Loss of import capacity by the petiole is both basipetal and dorsoventral. The proximal, adaxial portion of the petiole is the last region to cease importing 14C. Leaves of Beta vulgaris L. and Nicotiana tabacum L. also lose import capacity in a basipetal direction.

    The effect of drawing on the transport of gases through polyethylene (1993)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 31 (1993), S. 743-757 
    Details
    ISSN: 0887-6266

    Topics: Chemistry and Pharmacology , Physics
    Notes: A study has been made of the gas transport properties of polyethylene films of two different grades, Hizex 7000F and Rigidex 002-55, one-way drawn at 115°C to draw ratios in the range 1-20. Measurements of the permeability and diffusion coefficients of helium, oxygen, carbon dioxide and nitrogen have been made with a dynamic flow rate technique, utilizing a mass spectrometer detection system, and of oxygen using a commercial OXTRAN system. The samples were characterized by the measurement of density, birefringence and modulus and by wide-angle x-ray diffraction and differential scanning calorimetry. There is a large decrease in both the permeability and diffusion coefficients for all gases with increasing polymer draw ratio, with up to an 80-fold decrease in permeability for the larger permeants compared with the 10-fold decrease observed for helium. The solubilities of all the gases decrease only by a factor of ∼ 2. The diffusion results are discussed in terms of geometric impedance and chain immobilization factors. The solubilities, on the other hand, appear to relate primarily to the amorphous volume fraction of the polymer. © 1993 John Wiley & Sons, Inc.

    The Utility of Polarized Heliospheric Imaging for Space Weather Monitoring (2015)
    Wiley
    Details
    Publication Date: 2015-12-16
    Description: A polarizing heliospheric imager is a critical next-generation tool for space weather monitoring and prediction. Heliospheric imagers can track coronal mass ejections (CMEs) as they cross the solar system, using sunlight scattered by electrons in the CME. This tracking has been demonstrated to improve the forecasting of impact probability and arrival time for Earth-directed CMEs. Polarized imaging allows locating CMEs in three dimensions (3-D) from a single vantage point. Recent advances in heliospheric imaging have demonstrated that a polarized imager is feasible with current component technology. Developing this technology to a high technology readiness level (TRL) is critical for space weather relevant imaging from either a near-Earth or deep-space mission. In this primarily technical review, we develop preliminary hardware requirements for a space-weather polarizing heliospheric imager system, and outline a two-step plan to flight-qualify and ultimately deploy the technology operationally on upcoming specific missions: either as an instrument on NOAA's DSCOVR follow-on near the Sun-Earth L1 Lagrange point, as a standalone constellation of smallsats in low Earth orbit (LEO), or as an instrument located at the Sun-Earth L5 Lagrange point. The critical first step is the demonstration of the technology, in either a science or prototype operational mission context.
