Lissamingrün-Passagen in der Nierenpapille - Mesocricetus auratus (Muridae)

The film shows the passage of lissamin green in the renal papilla of a golden hamster (dye passage through vasa recta, loops of Henle, and collecting ducts). Particular attention is paid to the rhythmic transport of dye in the collecting duct system. Furthermore the passage of albumin cylinders in the collecting duct system is shown, whereby the effect of osmotic diuretics is demonstrated.

Lissamingrün-Passagen in der Nierenrinde - Rattus norvegicus (Muridae)

After showing the normal, decapsulated kidney surface of an anaesthetized albino rat, the film shows the passage of intravenously injected Lissamingreen on the kidney surface. The dye passes through the vasa efferentia, the proximal and the distal tubulus lumina at characteristic times, thereby permitting - in addition to the differentiation of proximal and distal tubuli - the determination of tubular flow rates. This is followed by a description of the behaviour of the proximal and distal tubuli lumina during interruption of glomerular filtration by clamping the aorta.

Maching process during the turning of thermoplastic polyamide 6 with carbide tipped tools. The work sample was machined longitudinally and vertically under normal V60 conditions with various cutting speeds and machining thickness, and the process was filmed both at normal speed and under magnification in slow-motion. Increasing machining thickness results in a change in the formation of the cuttings, namely from ribbon cuttings with smooth run-off to very irregular and awkward brittle cuttings, with unfavourable cutting surface finish.

Dromia vulgaris (Dromiidae) - Kampf um die Tarnbedeckung

Dromia vulgaris (Dromiidae) holds sponges or Ascidia colonies over its body by means of the specialised two last pairs of the cephalothorax appendages. If an uncamouflaged Dromia detects a camouflaged one, it approaches and climbs onto the cover. The camouflaged animal does not defend by means of chelipeds but only ducks in response to the mounting. The uncamouflaged crab climbs over the sponge towards the posterior, lifts the sponge with one claw and squeezes strongly one of the holding legs with its other claw. The assaulted animal moves forward and leaves the sponge loose, which the attacking crab now puts on its back. The film shows how a case changes owner several times. Intraspecific threat and fighting behaviour with the chelipeds as described for other water-living crabs, has not been observed in Dromia up to now.
