    Notes: [Auszug] A highly pathogenic avian influenza virus, H5N1, caused disease outbreaks in poultry in China and seven other east Asian countries between late 2003 and early 2004; the same virus was fatal to humans in Thailand and Vietnam. Here we demonstrate a series of genetic reassortment events traceable ...

    Notes: [Auszug] The highly pathogenic H5N1 influenza virus has become endemic in poultry in southeast Asia since 2003 and constitutes a major pandemic threat to humans. Here we describe cases of disease caused by H5N1 and transmission of the virus among migratory geese populations in western China. This ...

    Description / Table of Contents: Resume On considère une procédure d’échantillonnage qui consiste à appliquer les deux règles suivantes: (i) la valeur moyenne d’échantillons pris au hasard ne devrait pas être inférieure àa fois la valeur spécifiée officielle: (ii) tous les résultats d’essai individuels ne devraient pas être inférieurs àb fois la valeur spécifiée officielle. La régle d’échantillonnage proposée présente trois paramètres: la taille de l’éprouvette,n, et les constantesa etb. En faisant varier ces trois paramètres, la procédure d’échantillonnage donne lieu à un vaste éventail de courbes de fonctionnement caractéristique. et permet d’établir une courbe OC acceptable pour le producteur et le consommateur. On peut l’utiliser aussi pour produire une nouvelle règle de réception qui donnera une courbe OC similaire à celle d’une procédure d’échantillonnage existante. On propose une solution approchée pour le calcul de la courbe OC de la procédure proposée. On discute aussi les applications de cette procédure.
    Notes: Abstract A sampling scheme which consists of the following two sampling rules is considered: (i) the sample mean value of the random samples should not be less than a times the specified standard and (ii) all individual test results should not be less thanb times the specified standard. By varying the constantsa andb and the sampling size, the sampling scheme generates a wide range of operating characteristics (OC) curves. An approximate closed-form solution is proposed for calculating the OC curve of the proposed scheme. Applications of the scheme are also discussed.

    Acute alterations in systolic ventricular interdependence—mechanical dependence of right ventricle on left ventricle following acute alteration of right ventricular free wall (1993)
    Springer
    Basic research in cardiology 88 (1993), S. 350-361 
    Details
    ISSN: 1435-1803
    Keywords: Ventricular interdependence ; right ventricle ; hemodynamics ; ventricular infarction ; canine

    Notes: Summary The purpose of the study was to examine whether systolic ventricular interdependence can be acutely altered by changes in the mechanical properties of the ventricular wall. In eight acute canine studies, we released an aortic constriction during diastole. We measured right ventricular (RV) pressure changes (dPr) caused by sudden changes in left ventricular (LV) pressure (dPl). Measurements were obtained during control, 10 min after right coronary artery occlusion, and then 15 min after injecting glutaraldehyde into the RV free wall. By superimposing the pressure tracings of the beats immediately before and after the aortic release, the instantaneous pressure difference ratio (dPr/dPl) was calculated during systole. Maximal value of the pressure difference ratio decreased from control 0.11±0.04 to ischemia 0.08±0.03; (p〈0.05) and increased with glutaraldehyde 0.15±0.06; (p〈0.05). Thus, acute ischemia in RV free wall decreased the magnitude of systolic ventricular interdependence from LV to RV, while glutaraldehyde, which stiffens the RV free wall, increased the magnitude.

    Rapid evaluation of the critical slip surface in slope stability problems (1987)

    Notes: Existing approaches for locating the critical slip surfaces are briefly reviewed. A number of techniques and strategies are proposed whereby the efficiency and robustness of some of the existing approaches can be enhanced. A new solution scheme is also developed for rapid calculation of the factor of safety. The new solution scheme requires only one level of iterations in contrast to the conventional solution scheme which invoives two levels of iterations. It is also applicable to a variety of stability models. A new compound iterative procedure is developed whereby the factor of safety can be calculated to a high accuracy within a few iterations. This reduces greatly the total computer time required for locating the critical slip surfaces.
