Experiments on the Physiology of Heart and Circulation of the Rabbit

The experiments conducted in the closed thorax show several examples of control mechanisms of the cardiac and circulatory functions. Accompanied by consistent monitoring of the ECG, pulse frequency and blood pressure, the following interventions are performed: 1. Simultaneous ligature of the carotids, 2. Separate electrostimulation of the vagus nerves, 3. Intravenous injection of acetylcholine (neurotransmitter), adrenaline (hormone) and Verapamil (medicament, calcium antagonist).

Desiccation Cracks

The film introduces into the field of contraction phenomena and explains why desiccation cracks are formed. It describes the main features of desiccation cracks using both modern and fossil examples and demonstrates, via time lapse, how desiccation cracks develop in an experiment. The computer reproduces this process plotting the sequence of the digitized cracks. Graphic animation shows the interaction between tensile strength and tensile stress responsible for the information of the orthogonal crack pattern. Finally, the possible geological meaning of desiccation cracks is discussed.

Von der Hungerstraße ins Freilichtmuseum - Ein Tagelöhnerhaus zieht um

In May 1991 a day laborers' house was transported completely in a spectacular move from Rösebeck (near Höxter) to the Detmold open air museum.

What problems arise in the attempt to show the living of rural lower classes?

Euroleon nostras (Myrmeleonidae) - Schlüpfen der Imago

Metamorphosis of ant-lions takes place in a spherical cocoon of silk covered with grains of sand. After a period of about four weeks, the pupa uses its strong mandibles to bite a circular slit through the wall of the cocoon so that the top can be raised. Through the opening thus produced, the pupa emerges a little. The pupal skin splits along the back, and the imago starts to free itself. Initially, the appendages of the head and the legs are restrained inside the pupal skin and it takes some time to pull them out. After entirely having freed itself, the imago seeks a raised twig or stalk to spread from the base outwards. A few minutes later, the wings are rotated into the normal position above the abdomen. Soon after emergence, solidified remains of the larval food are discharged by the imago as a reddish meconial pellet. This is because during larval life the stomach does not communicate with the hindgut. During the course of a few hours, the integument hardens, adult coloration is assumed, and the ant-lion is ready to fly.
