  • Glossary Glossary
    Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

  • Observational Data Disfavor Dark Matter and Stochastic Star Formation
    1 Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation Pavel Kroupa Abstract: According to modern theory galactic evolution is driven by the dynamics of dark matter and stochastic star formation, but galaxies are observed to be simple systems. The existence of dark matter particles is a key hypothesis in present-day cosmology and galactic dynamics. Given the large body of high-quality work within the standard model of cosmology (SMoC), the validity of this hypothesis is challenged significantly by two independent arguments: (1) The dual dwarf galaxy theorem must be true in any realistic cosmological model. But the now available data appear to falsify it when the dark-matter-based model is compared with the observational data. A consistency test for this conclusion comes 8 from the significantly anisotropic distributions of satellite galaxies (baryonic mass < 10 M ) which orbit in the same direction around their hosting galaxies in disk-like structures which cannot be derived from dark-matter models. (2) The action of dynamical friction due to expansive and massive dark matter halos must be evident in the galaxy population. The evidence for dynamical friction is poor or even absent. Independently of this, the long history of failures of the SMoC have the likelihood that it describes the observed Universe to less than 10−4 %. The implication for fundamental physics is that exotic dark matter particles do not exist and that consequently effective gravitational physics on the scales of galaxies and beyond ought to be non-Newtonian/non-Einsteinian. An analysis of the kinematical data in galaxies shows them to be described in the weak-gravitational regime elegantly by scale-invariant dynamics, as discovered by Milgrom.

Determining the genetic diversity of a collection of field isolates and the mechanisms by which S. uberis colonises the host were the general aims of this project, in particular the determination of the basis for bacterial persistence despite antibacterial therapy. Multi-locus sequence typing identified high levels of recombination within the population, but also a single dominant clonal complex which comprised nearly all sequence types which were isolated from more than one animal. The dominant clonal complex also comprised isolates, derived, however, from both persistent and non-persistent infections, but RAPD typing demonstrated that these isolates can differ in genetic composition elsewhere in the genome.
