    The Disposal of Nuclear Waste: A Problem in Mass Management? (1989)

    Notes: A reference repository is examined for environmental compliance utilizing minimum performance standards as established by the Nuclear Regulatory Commission and the Environmental Protection Agency. These standards stipulate the amount of time the radionuclides must be retained in the barrier, the acceptable release rates from the barrier, and the acceptable mass release that can be registered at the accessible environment over a 10,000-year time frame. The only natural, or geologic barrier standard specified is a minimum ground-water travel time of 1000 years from the engineered barrier to the accessible environment. Other natural barrier processes including geochemical retardation and mass transfer, dilution, and dispersion are not specified. In attempting to determine the role that these unspecified components must play in order to comply with the mass release standard, we find that their role is minimal to the extent that virtually any rock type that can satisfy the minimum ground-water travel time of 1000 years will satisfy the mass release requirements at the accessible environment. Full compliance with a concentration standard at the accessible environment requires that the nuclides contained within the larger inventories be fully contained with the controlled zone between the engineered barrier and the accessible environment

    Filial cannibalism in burying beetles (1987)
    Springer
    Behavioral ecology and sociobiology 21 (1987), S. 179-183

    ISSN: 1432-0762

    Topics: Biology
    Notes: Summary Infanticide is a common phenomenon in many animal groups, but filial cannibalism, the deliberate killing and consumption by parents of their own young, is extremely unusual. The burying beetle Nicrophorus vespilloides Herbst has a limited food supply, in the form of a buried corpse, on which to raise its young. On corpses weighing 10–15 g, clutch size in the lab is such that complete hatching can support without severe reduction in the individual weights of final instars. The parents reduce the brood by killing and eating almost half of the first stage larvae. It is suggested that, in the field, predation of eggs and newly hatched larvae may be heavy, and that the excess eggs are laid as an insurance. If survival is then unusually high, superfluous young are killed by the parents before competition for food can occur.

    Brood size and fitness in Nicrophorus vespilloides (Coleoptera: Silphidae) (1988)

    Notes: Summary Using a laboratory population of the burying beetle Nicrophorus vespilloides (Coleoptera: Silphidae) the effects of body size on fighting ability and reproductive capacity were studied. The outcome of fights for corpses was found to depend on body size and was not related to order of arrival at a corpse. The size of a single clutche on a large corpse and the total of several clutches on a sequence of corpses increased with increasing female size. Larval weight and subsequent adult size for larvae raised on 10 g and 30 g mice were compared. Broods are culled on the smaller mice and light larvae eclose as relatively large adults for their weight; however larvae and adults from small corpses were still lighter and smaller than larvae and adults from 30 g corpses.

    Male mating success and paternal care in Nicrophorus vespilloides (Coleoptera: Silphidae) (1988)

    Notes: Summary If no female is present, male burying beetles Nicrophorus vespilloides (Coleoptera: Silphidae) co-operate in the burial of a corpse. Once a female has arrived, the males fight with one another. The defeated male stays near the corpse and to copulate with the female. Laboratory experiments using sterilised males showed that the defeated male was able sometimes to father some of the offspring raised on the corpse. Male N. vespilloides almost always participate in defence and feeding of the brood. This is not affected by the size of the male. Males quickly leave or are driven from 5 g corpses. Males feed the larvae as often as females do, and larvae raised by males alone are not significantly different in weight from larvae raised by females alone or by both parents. Males which cared for a succession of broods in the laboratory did not differ significantly in median lifespan from males which were removed from their corpses after eggs had been laid. Non-caring males weighed significantly more than caring males over a sequence of corpses, but the caring males did not differ significantly in weight from non-breeding controls.

    Origin of regenerating Leydig cells in the testis of the adult rat (1987)
    Springer
    Cell & tissue research 249 (1987), S. 367-377

    Notes: Summary Ethane dimethanesulphonate (EDS) was used as a specific cytotoxin to eliminate the Leydig cell population of the adult rat testis. Ultrastructural, morphometric and serum gonadotrophin and testosterone analysis was used to study the response of the intertubular tissue of the testis from 1 day to 10 weeks after EDS treatment. In control animals, the testis contained approximately 28 million Leydig cells and 8 million macrophages. Three to seven days after EDS treatment, Leydig cells were absent and serum testosterone was undetectable. Macrophage numbers increased three-fold by 3 days and returned to pretreatment values thereafter. At 2 and 3 weeks post-EDS, foetal-type Leydig cells (∼1–2 million per testis) appeared in proximity to perivascular and peritubular tissues, a feature also observed at 4 weeks when numerous such cells (∼15 million per testis) formed prominent clusters in perivascular and peritubular locations. Between 6 and 10 weeks after EDS treatment, the foetal-type Leydig cells were transformed morphologically into adult-type Leydig cells, they occupied central intertubular positions and their numbers were restored to pretreatment values. Regeneration of Leydig cells was reflected by elevated serum testosterone levels which returned towards the normal range. The results demonstrate the regenerative capacity of the testicular intertubular tissue and indicate a dual site of origin of Leydig cells which initially resemble foetal-type Leydig cells prior to establishing the adult-type Leydig cell population. The morphological pattern of Leydig cell regeneration suggests that in addition to gonadotrophic stimulation, local testicular factors from the seminiferous tubules may stimulate Leydig cell growth.

    Methyl α-cyanoacrylate. II. Copolymerization studiesPresented in part at the 136th Meeting of the American Chemical Society, Atlantic City, New Jersey, September 1959. (1965)

    Notes: Copolymerization of methyl alpha;--cyanoacrylate with five reference monomers gave values e = +2.1 and of log Q = 0.65, with much scatter in the latter value. Alternating copolymers are formed by copolymerization with monomers of e = -0.8 or less. Bulk copolymerization with such monomers could not be accomplished, as a rapid noncatalyzed polymerization occurred upon mixing even at 0°C. Random copolymers with methyl methacrylate could be prepared in bulk; those with ca. 10% methyl methacrylate had physical properties similar to the homopolymer of methyl α--cyanoacrylate, except that the heat distortion temperature was lowered 10-15°C. The alternating copolymers were more thermally stable than the random copolymers. Glass temperature values for alternating copolymers do not appear to agree with values predicted from equations for random copolymers.
