The transient photovoltaic (PV) characteristic of HgCdTe PV array is studied using an ultrafast laser. The photoresponse shows an apparent negative valley first, then it evolves into a positive peak. By employing a combined theoretical model of pn junction and Schottky potential, this photo-response polarity changing curves can be interpreted well. An obvious decreasing of ratio of negative val...

In this paper, the so-called V-chip is analysed from the perspective of responsibility. The V-chip is a technological tool used by parents, on a voluntary basis, to prevent children from watching violent television content. Since 1997 in the United States, the V-chip is installed in all new televisions sets of 12″ and larger. We are interested in the question whether and how the introduction of...

Die Identifikation von Ventilationsmechanik und Gasaustausch mit einem vereinigten Modell liefert für die beiden wichtigsten Klassen von Modellen zur Beschreibung physiologischer und pathologischer Eigenschaften der Lungen erstmals konsistente patientenspezifische Parameter. Dies ist sowohl für die medizinische Grundlagenforschung als auch für die Weiterentwicklung computergestützter Systeme zu...

Human voice is a gender discriminating cue and is important to mate selection. This study employed electrophysiological recordings to examine whether there is specific cerebral activity when presented with opposite-sex voices as compared to same-sex voices. Male voices and female voices were pseudo-randomly presented to male and female participants. In Experiment 1, participants were instructed...

Dieser Beitrag untersucht die Anforderungen an Kompetenzmanagementlösungen (als Oberbegriff zu Skillmanagement) im betrieblichen Umfeld unter Berücksichtigung ihrer Anpassungsfähigkeit im Zeitverlauf. Unter Verwendung von Ergebnissen aus der Aktionsforschung und vergleichender Fallstudienanalyse produktiver Kompetenzmanagementlösungen entwickeln die Autoren ein Lebenszyklusmodell, das die in de...

We describe a case of urethritis caused by group B streptococci. The diagnosis was confirmed by examination of a Gram stained smear, isolation of the organism from the urethral discharge, and also by the clinical response to treatment with phenoxymethyl penicillin.
