A new approach is presented for the evaluation of cephalometric measurements in which a measurement is considered to be a diagnostic test for the presence or the absence of some component of malocclusion. This approach allows cephalometric measurements to be judged by the criteria that are generally used for clinical diagnostic tests, including(More)
Suckling was studied in infant miniature pigs to determine (a) the necessary stimulus for eliciting rhythmic behavior and (b) whether the rhythm of the feeding movements could be entrained with a rhythmic pulsed delivery of milk. The animals fed on an automated milk delivery system, which supplied pulses of milk either at fixed, predetermined rates or on(More)
Somatic growth is not a simple linear process with a constant rate of growth. The most successful attempts to quantify growth as a function of age or size have employed nonlinear techniques. Sexual dimorphism of primate growth, weight vs. age, was examined using nonlinear models with Sirianni and Swindler's ([1985] Growth and Development of the Pigtailed(More)
The noninvasive signal-averaged electrocardiographic detection of late potentials correlates with the spontaneous occurrence of sustained ventricular tachycardia (VT). Frequency analysis of the electrocardiographic signal from the terminal QRS and ST segment also correlates with sustained VT. This study was designed to compare these 2 methods by analysis of(More)
Little is known about the relationship between the age of the skeleton and the development of multinucleated bone-resorbing cells, osteoclasts. It has been shown that mineralized bone implanted onto the chick chorioallantoic membrane (CAM) is effective in the recruitment and differentiation of osteoclast precursors. In studies reported here we used the CAM(More)

Die Tatsache, dass sich globale IT-Konzerne in jüngster Zeit Kommunen und Regionen als Partner für die Planung, Implementierung und den Betrieb regenerativer Energiesysteme anbieten, signalisiert einen Paradigmenwechsel am Energiemarkt. Es wird künftig eine zunehmende Pluralität von Geschäftsmodellen hin zu intelligenten, verteilten Energie- und(More)
Today's society is exposed to an increasing number of disasters and large scale emergencies (e.g. earthquake in Haiti, global swine flu, or manmade disasters like the oil spill in the Gulf of Mexico). Information and communication technology (ICT) can help to prevent and mitigate the effects of threatening situations if applied appropriately. In industry(More)
