    Description / Table of Contents: Résumé Sur 24 membres de cadavres la vascularisation du paquet adipeux antérieur d'Hoffa a été étudiée par injection. Sur certains sujets, nous avons réalisé l'intervention décrite par Clancy (opération plastique de remplacement du ligament croisé antérieur par un tiers de tendon rotulien pédiculé à partir du paquet adipeux antérieur d'Hoffa). Il apparaît que ce paquet adipeux antérieur d'Hoffa est directement vascularisé par les artères articulaires supéro-et inféro-externes et internes, l'artères articulaires moyenne du genou par le ligament adipeux et l'artère récurrente tibiale antérieure. Ces vaisseaux forment également le réseau vasculaire du tissu conjonctif du tendon rotulien d'où ce tendon tire sa vascularisation. Au niveau des insertions sur le tibia et sur la rotule aucun vaisseau sanguin provenant de l'os ne pénètre le tendon. Le tiers médian du tendon rotulien pédiculé sur le paquet adipeux antérieur reste normalement irrigué après la préparation nécessaire à l'opération. La majorité des vaisseaux sanguins du paquet adipeux antérieur d'Hoffa pénètre le ligament à son point d'attache.
    Notes: Summary In 24 fresh specimens the blood-supply of the infrapatellar fat-pad was investigated by injection. In some of the specimens, Clancy's pedicled patellar tendon graft for anterior cruciate ligament reconstruction had been performed before injection. The fat-pad is supplied by vessels forming a plexus supplying the tendon. In the tendon grafts injected after Clancy's procedure, no vessels were found penetrating the patellar tendon at its patellar and tibial attachments. Filled vessels were found by histologic methods and the Spalteholz technique.

    Artifacts in the adiabatic approximation (1985)

    Notes: Generally, the adiabatic approximation is defined via a projection onto an adiabatically moving electronic base. The Hamiltonian then is separated into three constituents ("adiabatic,'' "diagonal-nonadiabatic,'' "nondiagonal-nonadiabatic''). A model system is considered for which the correct zero-order eigenfunctions are known. It is shown that with these any single of the three Hamiltonian constituents yields diverging expectation values; only their sum yields convergence. From this the conclusion seems stringent that any result pertaining to electronic transitions, which is based on the adiabatic approximation, is an artifact.

    Multijunction upper subcell cascade photovoltaics for space applications (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 540-546 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: A new class of cascade high-efficiency photovoltaics designed for space-based applications is proposed. The design improves upper subcell performance and avoids electrical and optical losses associated with an intercell ohmic contact. Multijunction upper subcells reduce bulk recombination of photogenerated minority carriers by decreasing the average collection distance, yielding improved spectral response and radiation tolerance. A three-terminal design is employed which circumvents the need for a monolithic intercell contact and, thus, the losses associated with such a contact. Problems related to array interconnection of three-terminal devices may be solved by creating a two-terminal cell from complementary pairs (n-p-n and p-n-p) of three-terminal cells. Simulations of lattice-matched AlGaAs-GaAs and lattice-mismatched AlGaAs-InGaAs cascade cells show that one-sun AM0 efficiencies in excess of 26% and 28%, respectively, are possible.

    Explosive crystallization in silicon (1986)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 59 (1986), S. 3091-3099

    Topics: Physics
    Notes: A survey of the possible autocatalytic crystallization processes called explosive crystallization in liquid and solid states is given. The explosive liquid-phase epitaxy with laterally moving coupled interfaces of melting and crystallization in amorphous silicon layers on insulators is investigated by the use of an experimental equipment consisting of three synchronized lasers supplying the temperature pulses for ignition, spreading, and stopping of the explosive front. The velocity of this explosive crystallization front measured by use of time-resolved reflectivity of a test beam is compared with the results of model calculations. The results are in good agreement. The crystal structure was investigated by optical and transmission electron micrography and represents crystalline laminae grown preferentially in the 〈110〉 direction over a distance of about 100 μm. Areas of some millimeters in diameter can be crystallized by this method.

    Effect of Sodium Acid Pyrophosphate and/or Potassium Sorbate on Staphylococcus aureus FRI-100 Growth and Toxin Production (1987)

    Notes: The effect of food-grade sodium acid pyrophosphate (SAPP) alone or in combination with potassium sorbate (PS) on growth and toxin production by an enterotoxin A producing strain of Staphylococcus aureus was investigated. Growth of cultures was monitored by absorbancy readings (640 nm) at 5-hr intervals. Toxin production was determined by an Enzyme Linked Immunosorbent Assay (ELISA). SAPP (0.04%) in combination with PS (0.26%) was the most favorable treatment for inhibition of S. aureus growth. Concentration of toxin correlated with amount of growth in all treatments studied.

    Influence of watering and trenching ponderosa pine on a pine sawfly (1987)

    Notes: Summary Neodiprion autumnalis (Smith) larvae were caged for two successive years on root-trenched, watered, and untreated ponderosa pine (Pinus ponderosa Doug. ex Laws.) to determine effects of host moisture stress on larval feeding. Levels of moisture stress (as measured by the Scholander pressure chamber) differed significantly among treatment levels during 1984 and 1985 larval feeding periods. Differences in larval feeding success were not detected in 1984. In 1985, however, larvae on trenched (stressed) trees clipped and rejected more foliage, consumed more needles, had lower pupal weights, lower survival, and a longer feeding period than larvae on watered or untreated trees. Frass production did not differ among treatment levels. The length of the feeding period was shorter for larvae on watered trees than for larvae on untreated trees, but other measures of feeding success did not significantly differ between watered and untreated trees.

    Mediastinal lipomatosis: a complication of high dose steroid therapy in children (1988)
    Springer
    Pediatric radiology 19 (1988), S. 57-58 
    Details
    ISSN: 1432-1998
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Mediastinal lipomatosis has been described in adults and is a well recognized cause of mediastinal enlargment [1–2]. Fatty accumulation in the mediastinum has been observed following extended usage of large doses of steroids, generally greater than 60 mg daily. Little documentation of this entity exists in pediatric patients. A 9-year-old male who received large doses of steroids for graft-versus-host disease following bone marrow transplantation for acute myelogenous leukemia developed mediastinal lipomatosis. Early qualification of this diagnosis is especially important in this group of patients, who are also at risk for a second neoplasm [3].

    Diagonalization of the Rabi Hamiltonian by means of a unitary transformation (1985)
    Springer
    The European physical journal 58 (1985), S. 255-258 
    Details
    ISSN: 1434-6036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A unitary transformation is derived which diagonalizes the Rabi Hamiltonian. While the solution of this diagonalization problem by standard methods has long been known, it is found that the unitary operator is of a form which has previously not been used in the connexion with spin-boson problems. The transformed Hamiltonian as well as some other characteristic transformed operators are calculated. A comparison is made between the exact unitary operator and a weak coupling transformation which is equivalent to second order perturbation theory.
