    Notes: The effect of germination on total nitrogen (TN), protein nitrogen (PN), total nonprotein nitrogen (NPN), free amino acid nitrogen (FAAN), and amino acid composition of three varieties of pea seeds (Dwarf Gray, Early Alaska, and Wando) was studied. Following 5 days of germination, there was a slight increase of TN, a slight decrease of PN, and a marked increase of both the total NPN and FAAN in all varieties of seeds when compared on a dry weight basis. In germinated seeds, TN ranged from 3.49–4.98, PN ranged from 2.60–3.48, total NPN from 0.893–1.502, and FAAN ranged from 0.408–1.313 g/100g dry weight. Whereas, in ungerminated seeds, TN ranged from 3.20–4.72, PN ranged from 2.93–4146, total NPN ranged from 0.263–0.337, and FAAN ranged from 0.067–0.150 g/100g dry weight. The altered amino acid patterns of ungerminated and germinated seeds suggest that there was a turnover of proteins and amino acids under the experimental conditions.

    Notes: The effect of germination on the blood hem agglutinating activity (BHA) of eight varieties’ of pea and bean seeds was studi Ed. Among seeds, the BHA of Wando, Laxton Progress, Pinto and soybean was the highest, that of Mung bean was the lowest. The BHA decreased progressively with days of germination. After 4 days of germination, the BHA of seeds decreased to the following percentages of ungerminated seeds: Dwarf Gray pea, 16.3%; Early Alaska pea, 8.1%; Laxton Progress pea, 5.3%; Mammoth Melting pea, 9.1%; Wando pea, 5.1%; and soybean, 3.7%. The BHA of Mung bean and Pinto bean disappeared completely after 4 days of germination. This study shows that an antinutritive factor, hemagglutinin, of seeds was decreased by germination.

    Association of color and feeding deterrence by tropical reef fishes (1999)

    Notes: Summary. While many marine molluscs have been suggested to use aposematic coloration to avoid predation, few studies have tested the ability of marine predators to learn to associate colors with distasteful prey. In field experiments, we tested the ability of two populations of reef fishes to discriminate among red, yellow, and black artificial nudibranch models when one color was paired with a feeding deterrent. We offered fishes (1) the models without any feeding deterrents, (2) the models with a feeding deterrent coated onto one color, and (3) the models without deterrents again. If reef fishes learn to associate colors with noxious prey, we expected the color paired with the feeding deterrent to be eaten less frequently in the final assay than the initial assay. In both populations, fishes formed clear associations between color and feeding deterrence. However, when the experiment was repeated in one population, changing the color paired with the feeding deterrent, fishes did not form an association between color and feeding deterrence. In this case, prior learning may have affected subsequent trials. Our study indicates that common colors of nudibranchs are recognizable by fishes and can be associated with noxious prey.

    Notes: Summary Specimens ofAbies sp. (fir),Pinus longifolia (chir),Vateria indica (vellapine),Dichopsis elliptica (pali) andMangifera indica (mango) were impregnated with monomers of styrene and methylmethacrylate and irradiated under different conditions. The treated specimens were tested as to their crushing strength, their bending strength and their water absorption. The results first indicate and increase in density due to impregnation. A reduction in moisture absorption and volumetric swelling as compared with untreated controls and increase in crushing strength were observed. The properties varied due to a non-uniform penetration of the polymer. Further experiments on the resistance against degradation by fungi were carried out and respective results are listed and discussed.

    Accretion disc particle accretion in major merger simulations (2013)
    Oxford University Press
    Details
    Publication Date: 2013-04-03
    Description: A recent approach to simulating localized feedback from active galactic nuclei (AGN) by Power et al. uses an accretion disc particle to represent both the black hole and its accretion disc. We have extrapolated and adapted this approach to simulations of Milky Way sized galaxy mergers containing black holes and explored the impact of the various parameters in this model as well as its resolution dependence. The two key parameters in the model are an effective accretion radius, which determines the radius within which gas particles are added to the accretion disc, and a viscous time-scale which determines how long it takes for material in the accretion disc to accrete on to the black hole itself. We find that there is a limited range of permitted accretion radii and viscous time-scales, with unphysical results produced outside this range. For permitted model parameters, the nuclear regions of simulations with the same resolution follow similar evolutionary paths, producing final black hole masses that are consistent within a factor of 2. When comparing the resolution dependence of the model, there is a trend towards higher resolution producing slightly lower mass black holes, but values for the two resolutions studied again agree within a factor of 2. We also compare these results to two other AGN feedback algorithms found in the literature. While the evolution of the systems vary, most notably the intermediate total black hole mass, the final black hole masses differ by less than a factor of 5 among all of our models, and the remnants exhibit similar structural parameters. The implication of this accretion model is that, unlike most accretion algorithms, a decoupling of the accretion rate on to the black hole and the local gas properties is permitted and obtained; this allows for black hole growth even after feedback has prevented additional accretion events on to the disc.

    nIFTy galaxy cluster simulations - I. Dark matter and non-radiative models (2016)
    Oxford University Press
    Details
    Publication Date: 2016-03-02
    Description: We have simulated the formation of a galaxy cluster in a cold dark matter universe using 13 different codes modelling only gravity and non-radiative hydrodynamics ( ramses , ART, arepo , hydra and nine incarnations of gadget ). This range of codes includes particle-based, moving and fixed mesh codes as well as both Eulerian and Lagrangian fluid schemes. The various gadget implementations span classic and modern smoothed particle hydrodynamics (SPH) schemes. The goal of this comparison is to assess the reliability of cosmological hydrodynamical simulations of clusters in the simplest astrophysically relevant case, that in which the gas is assumed to be non-radiative. We compare images of the cluster at z  = 0, global properties such as mass and radial profiles of various dynamical and thermodynamical quantities. The underlying gravitational framework can be aligned very accurately for all the codes allowing a detailed investigation of the differences that develop due to the various gas physics implementations employed. As expected, the mesh-based codes ramses , art and arepo form extended entropy cores in the gas with rising central gas temperatures. Those codes employing classic SPH schemes show falling entropy profiles all the way into the very centre with correspondingly rising density profiles and central temperature inversions. We show that methods with modern SPH schemes that allow entropy mixing span the range between these two extremes and the latest SPH variants produce gas entropy profiles that are essentially indistinguishable from those obtained with grid-based methods.
