    Notes: . A series of new in vitro systems for the cultivation of bloodstream forms of Trypanosoma (Trypanozoon) brucei brucei, T. (T.) b. rhodesiense, and T. (T.) b. gambiense was developed. The standard system consists of a feeder layer of fibroblast-like cells derived from embryos of New Zealand White rabbits (REF) or a mountain vole, Microtus montanus (MEF), with HEPES-buffered Minimum Essential Medium (MEM), with Earle's salts, supplemented with 15% inactivated rabbit serum. These two and other feeder layers were cross-checked with different sera to test for growth support of bloodstream forms of the three trypanosome subspecies studied. Cultures could be initiated with bloodstream forms from mammalian hosts or from cryopreserved stabilates. Metacyclic forms from infected Glossina m. morsitans could also be used as inoculum; they transformed within 6 h to bloodstream forms. Maintenance of cultures and growth properties are described in detail. Experiments were undertaken to confirm that the cultivated bloodstream forms still possess some of the characteristic features of pleomorphic bloodstream populations. Cultivated bloodstream forms were always infective for mice, and a surface coat could be demonstrated by electron microscopy. They could also be cyclically transmitted through tsetse flies, and the metacyclic forms from these flies could be brought back into culture. In vitro cloning with single bloodstream forms and metacyclic forms could be achieved with high cloning efficiency. The consumption of glucose and the production of pyruvate and lactate were determined.

    Shock induced Rayleigh–Taylor instability in the presence of a boundary layer (1988)

    Notes: The aim of this work is an experimental study of the development of perturbations of a gaseous interface impulsively accelerated by a plane shock wave. The experiments are performed in a double diaphragm shock tube, where the second diaphragm is a very thin Mylar film which can be initially bulged because of a pressure difference between the two gases. The shape of the leading front of the contact zone is measured at three locations along the tube using a transversal array of heat transfer gauges. After the shock passage, the evolution of the interface is sensitive to vorticity production and boundary layer effects so that the impulsive Rayleigh–Taylor theory is inadequate for the description of this evolution. In particular, the predicted perturbation reversal when the shock wave passes from the heavy gas to the light one may not occur because of the boundary layer effect.

    Notes: In recent times a new, so-called »anthropological Psychology«, taking its origin from phenomenology and existential philosophy, has succeded in gaining ever increasing ground. It attempts to interpret human existence primarily in terms of the »self«- consciousness of the cultivated adult civilized person, in doing which, human values ultimately always are derived from an extra-human, supranaturalistic frame of reference as categorical imperatives. In contrast, thereto, biological psychology tries to explain human existence and behaviour exclusively in terms of man's own real biological world, i. e. of his own biological realm. Account is taken therein, in contrast to neoanthropological psychology, of the earlier historic stages of humanity, of the bodily and ontogenetic conditions of human behaviour on the basis of the mneme, and of the theories of drives and instincts, and thus the specifically human values are derived genetically from the instinctive needs.

    Notes: Described is how a pair of wild spawners of the critically endangered common Atlantic sturgeon, Acipenser sturio L., were induced to provide progeny despite their unsuitable reproductive states. When captured, the female revealed signs of over-maturation. The male, caught in brackish water, yielded no sperm; after 5 days in fresh water and with pituitary injection, motile spermatozoa were produced. A batch of 30% fertilized eggs was produced with a two-injection sequence. As opposed to the Siberian sturgeon, A. baeri, the A. sturio L. hatchlings showed no positive phototaxis.

    Motility analysis and energetics of the Siberian sturgeon Acipenser baerii spermatozoa (1999)

    Notes: A study of motility was carried out on spermatozoa of the Siberian sturgeon (Acipenser baerii Brandt) reared at the Cemagref experimental research station, St Seurin sur l'Isle, France. About 90% spermatozoa are activated within a few seconds after a double step dilution (final dilution 1/600) and the number of motile cells declines regularly to 10–20% after 2 mn. During the same period of time, the flagellum beat frequency remains stable at about 50 Hz for 30 sec and drops to 30 Hz after 60 sec. A morphological analysis of the movement of the flagellum shows that during the first 20 sec, waves are distributed on the entire length of the flagellum; later, they disappear progressively from the distal part within 1 mn in the case of 90% of the spermatozoa. Finally after 2 mn, most of the flagella are straight and devoid of wave. The ATP content declines very rapidly after activation from 7.58 ± 1.85 to 4.05 ± 1.51 nmol/108 spermatozoa within 5 sec (P=0.004). Spermatozoa left in the genital tract of the males over a period of 24 hrs (in vivo survival) do not show significant change in the percentage of motile cells (82 ± 14 vs 74 ± 15) nor in the ATP content (6.13 ± 2.37 vs 4.59 ± 1.42 nmoles/108 spermatozoa). An aliquot of these spermatozoa stripped from testis and stored during the same period of 24 hrs at 4°C shows a significant decrease in the percentage of motile cells from 82 ± 14 to 59 ± 30 (P〈0.01) and in the ATP content from 6.15 ± 2.4 to 1.95 ± 1.37 nmoles/108 spermatozoa (P=0.001).
