    Notes: Summary In this study we extracted guinea pig brain and testis with; the extract was adsorbed to and eluted from cartridges (the Sep-Pak C 18 procedure). We found this procedure superior for recovering crystalline insulin added to buffers or tissues, and for recovering endogenous insulin from plasma, but inferior for recovery of insulin from tissues. However, we did find ‘rat/pork’ type-insulin in guinea pig brain and testis (5–50 pg/g wet weight tissue). Our results with the Sep-Pak C18 procedures were reproduced by four other laboratories (who found 4–60 pg/g wet weight of tissue) and similar findings were also obtained by an independent investigator. Thus, we conclude that extrapancreatic tissues of guinea pigs have a second type of insulin-related material that is more typical of other mammalian insulins, but that the amount recovered is dependent upon the extraction procedure utilized.

    Notes: Summary Simultaneous right heart catheterization and radionuclide ventriculography were performed in 27 patients with a wide range of chronic obstructive pulmonary disease. Central hemodynamics and radionuclide studies were done at rest and during exercise. In the resting state the right ventricular ejection fraction (RVEF) was in the normal range (43.3±6%). During exercise a significant (p〈0.001) decrease of RVEF to 38.8±6.7% occurred. The pumonary artery mean pressures were 19.9±3.8 at rest. During exercise a significant (p〈0.001) increase to 41±9.8 mm Hg occurred. There was a linear relationship between pulmonary pressures and RVEF during exercise in patients with pulmonary artery pressures not exceeding 35 mm Hg. In patients with right ventricular end-diastolic wall thickness ≧6 mm a curvilinear relationship between these parameters could be observed with a flattening of the curve at higher pressures (〉35 mm Hg) and lower ejection fractions (〈35% RVEF). Radionuclide venticulography cannot substitute for right heart catheterization. Echocardiography is useful for interpretation of right ventricular ejection fractions in advanced chronic obstructive pulmonary disease.

    Notes: A deceleration system for a parallel ion beam in the energy range of 50 to 500 eV is described. The system is used for sputtering yield measurements as a function of the angle of ion incidence. Measured yield data for Cu and Au sputtered by 100- and 300-eV D+ ions are reported and compared to computer calculations. Experimental and calculated data show only a weak dependence on the angle of incidence. However, at glancing incidence the experimental values are larger up to a factor of 2 compared to the calculated ones. This is attributed to the surface roughness not included in the calculations.

    Mechanism of hydrocarbon formation upon interaction of energetic hydrogen ions with graphite (1987)

    Notes: The current model for hydrocarbon formation upon the interaction of energetic hydrogen ions with graphite assumes a reaction of adsorbed hydrogen with carbon surface atoms requiring a temperature of 800–900 K. This model is strongly questioned by results of hydrocarbon formation from a layered 13C/12C sample and by desorption measurements after room-temperature implantation. The formation of 13CD4 and 12CD4 is monitored during deuterium bombardment of a pyrolytic graphite sample covered with a layer of 200 A(ring) of 13C. Only for ion energies corresponding to ranges smaller than 200 A(ring) 13CD4 dominates, while at higher energies only 12CD4 is found. The methane is thus formed at the end of ion range rather than in a surface reaction of back-diffusing ions. Desorption experiments using a slow temperature range after room-temperature implantation show the release of CD4 prior to D2, thus indicating a diffusion-limited release of CD4 already formed during the implantation.

    On the growth of segregated C layers on top of Fe films on pyrolytic graphite samples during high-fluence D+ irradiation at elevated temperature (1989)

    Notes: On Fe films evaporated on pyrolytic graphite, thick C layers segregate during high-temperature (above about 800 K) light ion irradiation if the penetrating ions are energetic enough to reach the Fe-graphite interface. The thickness of the C segregated layer and the C depth distribution in the Fe film have been determined with 2-MeV 4He+ Rutherford backscattering. A steady-state carbon overlayer is reached at high fluences (above about 1019 particles/cm2), the thickness of which depends on the energy of the irradiating beam for a given thickness of the Fe evaporated film. The anisotropic structure of the pyrolytic graphite substrate influences the thickness of the steady-state C overlayer, thicker C layers being measured for edge-oriented C substrates. Using the Monte Carlo code trim, the production of defects in the graphite substrate has been calculated for different thicknesses of the C overlayer. The total amount of defects produced in the graphite substrate has been identified as the parameter regulating the growth and the steady-state value of the C overlayer. With the depth distributions of defect production generated by trim as source functions, the diffusion of C interstitials in graphite under the influence of recombination with vacancies has been modeled. The segregating C fluxes are identified with the fluxes of interstitials arriving at the Fe/graphite substrate interface for a suitable choice of the parameters in the diffusion equation.

    Computational treatment of collisional magnetic pumping (1989)

    Notes: When collisional magnetic pumping is applied to a plasma, the heating rate depends strongly on the nature of the waveform of the magnetic perturbation, whether sinusoidal, triangular, or sawtoothed in time. Numerical solutions to the energy transfer problem are obtained when these waveforms are applied to heat a plasma, and compared with previously obtained analytical results using small perturbation theory where these results are available. A specially written fortran program computes the numerical values of the parallel, perpendicular, and total energy at each time increment. The plasma heating rates and optimum heating conditions derived from this study are in good agreement with analytical limiting cases and available experimental data, except when the perturbation amplitude becomes large enough that the analytical results no longer hold.

    Theory of first-order plasma heating by collisional magnetic pumping (1989)

    Notes: Plasma heating by collisional magnetic pumping is investigated theoretically. This treatment yields solutions to the energy transfer equations in the form of an energy increase rate, which gives quantitatively the amount of energy increase per rf driving cycle. The energy increase rates (or heating rates) proportional to the first and second powers of the field modulation factor δ (defined as the ratio of the change in the magnitude of the magnetic field to its background dc value) are derived for an arbitrary rf waveform of the pumping magnetic field. Special cases are examined, including the sinusoidal and sawtooth pumping waveforms. The energy increase rate in the case of a sawtooth waveform was found to be proportional to the first power of δ (first-order heating). This heating rate is many orders of magnitude larger than heating for the sinusoidal case: The latter is proportional to the square of δ and is strongly dependent on the collisionality of the plasma. The use of a sawtooth pumping waveform improves the efficiency of collisional magnetic pumping and heating rates comparable to those possible with ion or electron cyclotron resonance heating methods may be achieved.

    Radiation damage and annealing in graphite implanted with H+2 and Mo+ (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 2603-2608

    Topics: Physics
    Notes: Radiation damage due to H+2 and Mo+ implantation into hot-worked pyrolytic graphite and into single-crystal graphite flakes has been studied using 1-MeV 4He+ ion channeling. The implant energies used, 35 keV for H+2 and 120 keV for Mo+, yielded ranges of about 1600 and 600 A(ring), respectively. For H2 implantation, a partially crystalline surface layer remains after a fluence of 2×1016 H/cm2; this layer is completely disordered at 2×1017 H/cm2. At higher hydrogen fluences a surface layer exfoliates. For Mo implantation the disorder introduced at a fluence of 5×1014 Mo/cm2 is sufficient to prevent channeling throughout the range. For both implant species, complete recrystallization of samples disordered up to the surface occurs for annealing only at temperatures above 2800 K. If a surface layer remains crystalline after implantation, recrystallization proceeds both from the bulk and from the surface, and crystallinity is restored at 2300 K. While hydrogen is known to be released at temperatures between 1100 and 1500 K, Mo remains within its original range distribution up to the temperature of complete recrystallization. At a temperature of 2300 K an ordering of the implanted Mo atoms with respect to the c axis is observed, indicating short-range migration within the range distribution. At 2800 K no more Mo could be found in the analyzed surface layer.
