To investigate the formation and the propagation of relativistic shock waves in viscous gluon matter we solve the relativistic Riemann problem using a microscopic parton cascade. We demonstrate the transition from ideal to viscous shock waves by varying the shear viscosity to entropy density ratio n/s. Furthermore we compare our results with those obtained by solving the relativistic causal dissipative fluid equations of Israel and Stewart (IS), in order to show the validity of the IS hydrodynamics. Employing the parton cascade we also investigate the formation of Mach shocks induced by a high-energy gluon traversing viscous gluon matter. For n/s = 0.08 a Mach cone structure is observed, whereas the signal smears out for n/s >=0.32.
Meeting Abstract : Gesellschaft für Arzneimittelanwendungsforschung und Arzneimittelepidemiologie e.V. (GAA). 17. Jahrestagung der Gesellschaft für Arzneimittelanwendungsforschung und Arzneimittelepidemiologie. Osnabrück, 25.-26.11.2010.
ntroduction: Several drugs require dose adjustment in patients with impaired renal function, which however, often goes undetected. Serum creatinine may be normal in patients while renal function is already reduced. The estimated GFR (eGFR) allows a more precise evaluation of the renal function. This study was carried out in a group practice for family medicine, in Frankfurt/ Main, Germany. The exploration aimed at investigating if patients with renal insufficiency were recognised and if their prescriptions were appropriate in terms of dose adjustment or contra-indications.
Methods: In patients (>65yrs) with renal insufficiency (creatinine clearance <60 ml/min), their prescribed medication was retrospectively explored (Observation period 1.1.2008 to 1.4.2009). The Cockroft-Gault formula was used as estimate for the eGFR, using a creatinine value from the patient’s charts. In 90 patients, a second eGFR could be estimated from a second creatinine value obtained within 3-6 months. The recommended dose of each prescription in the SmPC (Fachinformation“) was compared to the dose that had been actually prescribed.
Results: Out of 232 consecutively patients >65 yrs, 102 had an eGFR <60 ml/min, 16 of these had an eGFR <30 ml/min. The eGFR was closely correlated (r2=0.81) with an independent second eGFR. Out of these 102 patients, 48 had a serum creatinine level within the normal range. Renal adjustment was required in 263 of a total of 613 prescriptions. 72 prescriptions in a total of 45 patients were not appropriately adjusted (32) or prescribed despite a contraindication (40). For chronic prescriptions, metformin, ramipril, enalapril, HCTZ, and spironolactone accounted for 70% of inappropriate dosing; the magnitude of misdosing was 1.5 to 4 fold (median 2). 9 temporary prescriptions (of a total of 60 prescriptions) in 8 patients were not adjusted (cefuroxim, cefpodoxim, levofloxacin). We could not prove that patients with normal serum creatinine had a higher rate of inappropriate dosing than those with already elevated creatinine.
Discussion and conclusion: In this GP practice, we have demonstrated a considerable prevalence of inappropriate dosing in patients with impaired renal function. It remains to be elucidated whether surveillance of appropriate dosing in renal impairment can be optimized e.g. with CPOE.
ecently, pertussis has become a problem also in the adult population, with incidences even higher than in children. Pediatric health care workers (HCWs) are an important source of transmission, exposing very young and immunocompromised patients to an increased risk of potentially severe pertussis infections. Encouraging HCWs to get vaccinated can play a vital role in stopping the transmission of pertussis, thereby reducing institutional outbreaks.
In Germany, HCWs come up with all sorts of reasons for not getting pertussis vaccination. This study was meant to provide information in order to better understand the backgrounds of these attitudes.
A survey was conducted at the children's university hospital in Frankfurt, using an anonymous questionnaire. Survey results were used to design an intervention to increase the immunization rate of staff. Disappointingly, our efforts to increase the acceptance of the immunization program by providing information in advance were not yet satisfying.
Misconception about pertussis vaccination was prevalent especially among nursing staff. The main reasons for non-compliance included: unawareness of an own risk of infection, the belief that pertussis is not a serious illness, fear of side effects, the belief that the pertussis vaccine might trigger the pertussis disease itself, and skepticism about the efficacy of the pertussis vaccination.

Der (...) Beitrag setzt sich strukturell auf drei Ebenen mit Rolf Hochhuths Dramenpoetik auseinander. Erstens wird die gegenläufige Beziehung zwischen ihrem historisch-adäquaten Gestaltungsanspruch und ihrer literarisch-symbolhaften Überformung analysiert. Zweitens wird Hochhuths Verhältnis zu den für ihn poetologisch bedeutsamen Vorgängern Lessing und Schiller untersucht. Drittens geht es um die Frage, welche Konsequenzen sich aus der in den »Guerillas« formulierten Darstellungsabsicht ziehen lassen, der realen Wirklichkeit durch die Projektion einen neuen (literarischen) Wirklichkeit entgegenzutreten.
Der Vorhang öffnet sich zunächst nur einen Spalt zu Alban Bergs Oper Lulu, die anlässlich der Salzburger Festspiele 2010 in der Felsenreitschule inszeniert wurde. Zu erwarten ist, dass nun ein Sänger in der Rolle des Tierbändigers mit Hetzpeitsche in der einen und Revolver in der anderen Hand aus dem bunt gestreiften Vorhang wie durch den Eingang eines Zirkuszeltes schlüpft, um anzukündigen, dass in der nun folgenden Aufführung nicht – wie in gängigen "Lust und Trauerspielen" – lediglich gezähmte "Haustiere" gezeigt werden, sondern hier "[m]it heißer Wollust und mit kaltem Grauen" endlich "[d]as wahre Tier, das wilde, schöne Tier" erlebt werden kann.
We present results of lattice QCD simulations with mass-degenerate up and down and mass-split strange and charm (Nf = 2+1+1) dynamical quarks using Wilson twisted mass fermions at maximal twist. The tuning of the strange and charm quark masses is performed at three values of the lattice spacing a ~ 0:06 fm, a ~ 0:08 fm and a ~ 0:09 fm with lattice sizes ranging from L ~ 1:9 fm to L ~ 3:9 fm. We perform a preliminary study of SU(2) chiral perturbation theory by combining our lattice data from these three values of the lattice spacing.
