    Dynamics of collision-induced desorption: Ar–Xe/Pt(111) (1997)

    Notes: We have performed a detailed study of collision-induced desorption (CID) of Xe from Pt(111) by hyperthermal Ar atoms striking the surface. The study combines extensive molecular beam experiments with detailed molecular dynamics calculations in an effort to quantify fully and to understand in detail the dynamics of this model system. The calculations employ accurate semi-empirical potential energy functions for all relevant interatomic interactions. We have characterized the CID process with respect to incidence energy, Ei, angle, θi, and substrate surface temperature, Ts, for both the isolated adsorbate and the Xe/Pt(111) monolayer. The generally good agreement of the calculated results such as the desorption yield and desorbate energy and angular distributions with the experimental measurements demonstrates that the calculations capture the most important aspects of the CID processes. © 1997 American Institute of Physics.

    A first-principles potential energy surface for Eley–Rideal reaction dynamics of H atoms on Cu(111) (1999)

    Notes: We have performed first-principles total-energy calculations of low-dimensional sections of the electronically adiabatic potential energy surface (PES) that are relevant for the Eley–Rideal (ER) reaction of H atoms on a rigid Cu(111) surface. These calculations were performed within density-functional theory using a plane-wave and pseudopotential method and the generalized gradient approximation for the exchange-correlation energy. The calculated energy points for various configurations of one and two atoms on the Cu(111) surface were used to construct a model PES that can be used in ER reaction dynamics calculations. © 1999 American Institute of Physics.

    Toroidally localized and nonlocalized ballooning instabilities in a stellarator (1998)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 5 (1998), S. 2921-2931

    Topics: Physics
    Notes: It is shown that the coexistence of toroidally nonlocalized ideal-hydromagnetic ballooning instabilities, with a quasidiscrete spectrum, and toroidally localized ballooning instabilities with a broad continuous spectrum, as predicted by Dewar and Glasser [Phys. Fluids 26, 3038 (1983)] can be realized in a Mercier-unstable equilibrium case modeling the Large Helical Device (LHD) [A. Iiyoshi et al., Fusion Technol. 17, 148 (1990)] with a broad pressure profile. The quasidiscrete, interchange branch corresponds to extended modes that can be understood on the basis of a ripple-averaged ballooning equation, whereas the broad-continuum, ballooning branch corresponds to modes localized along a flux tube. The physical origin of the two branches is discussed. © 1998 American Institute of Physics.

    Drift waves in helical symmetry (1996)

    Topics: Physics
    Notes: The stable and unstable parts of the spectrum of the cold ion drift wave model are discussed in a helically symmetric stellarator model using a ballooning mode formalism. The presence of different types of eigenmodes is discussed. A study of the dependence of the growth of the modes on mode number, and other parameters, is also presented. © 1996 American Institute of Physics.

    Ballooning modes in the magnetohydrodynamic second stability region (1995)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 2 (1995), S. 3440-3446 
    Details
    ISSN: 1089-7674

    Topics: Physics
    Notes: The ion temperature gradient driven ballooning mode is investigated using two-fluid, gyrofluid, and gyrokinetic descriptions. The linear eigenmode equation is solved numerically in a model equilibrium with shifted circular magnetic surfaces. The localization of the eigenmodes, which persist in the magnetohydrodynamic (MHD) second stability region, and the mode structure, are displayed. The role of finite-Larmor radius (FLR) and magnetic drift resonance effects on the growth rate are elucidated. Negative magnetic shear is found to have a stabilizing effect on the mode. © 1995 American Institute of Physics.

    A search for association between schizophrenia and dopamine-related alleles (1996)
    Springer
    European archives of psychiatry and clinical neuroscience 246 (1996), S. 297-304 
    Details
    ISSN: 1433-8491
    Keywords: Schizophrenia ; Association study ; Dopamine receptors (DRD2, DRD4) ; Tyrosine hydroxylase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Dopamine receptor dysfunction and altered tyrosine hydroxylase activity have both been implicated in the pathophysiology of schizophrenia. Schizophrenic pationts and control subjects were examined for allele frequencies in the tyrosine hydroxylase and dopamine D2 and D4 receptor genes. No significant differences of allele or genotype frequencies were found between the two groups after adjustment for multiple comparison. Neither were any significant relationships observed between allele frequencies and a number of clinical variables within the schizoprenic subsample. When no adjustment was made for multiple testing a few significant tendencies were obtained which warrant further research in extended patient and control materials. The results are compatible with the view that the tyrosine hydroxylase, dopamine receptor D2 and D4 gene polymorphisms examined are not of major importance in the aetiology or pathophysiology of schizophrenia.

    Attitudes towards organ donation and transplantation – a study involving Baltic physicians (1998)
    Springer
    Transplant international 11 (1998), S. 419-423 
    Details
    ISSN: 1432-2277
    Keywords: Key words Attitudes ; organ donation ; Organ donation ; attitudes ; Organ donation ; Baltic states
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The aim of this study was to identify and describe attitudes towards organ donation and transplantation among a group of Baltic physicians who are involved in this aspect of medical care. A total of 151 neurosurgeons, anesthesiologists, and neurologists anonymously answered a questionnaire between February and March 1995. The majority of physicians said they would be willing to donate their own organs after their death but disagreed with the idea of using organs from a dead person who had had a negative opinion towards organ donation. Given a patient who fulfilled the criteria for brain death, this group of physicians found it widely acceptable to keep the patient on a ventilator until organ donation could take place. We conclude that the participating physicians generally have similar attitudes towards organ donation and transplantation. This study is valuable in that it shows the interest in, and the need for, clinical and research collaboration, including a discussion of ethics, within the area of organ donation and transplantation. This is essential for future collaboration with Western countries.
