Modelling Data

AbstractLiquid water in comets, once considered impossible, now appears to be almost certain. New evidence has come from the discovery of clay minerals in comet Tempel 1, which compliments the indirect evidence in aqueous alteration of carbonaceous chondrites. Infrared spectral indication of clay is confirmed by modelling data in the 8–40 μm and 8–12 μm wavebands on the basis of mixtures of clays and organics. Radiogenic heating producing liquid water cores in freshly formed comets appears more likely on current evidence for solar system formation. A second possibility investigated here is transient melting in comets in the inner solar system, where thin crusts of asphalt-like material, formed due to solar processing and becoming hot in the daytime, can cause melting of sub-surface icy material a few centimetres deep. Supposing comets were seeded with microbes at the time of their formation from pre-solar material, there would be plenty of time for exponential amplification and evolution within the liquid interior and in the transient ponds or lakes formed as the outer layers are stripped away via sublimation.

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.

Impfungen sind einfache und effektive Maßnahmen zur Verhinderung von Reisekrankheiten. Compliance-Probleme sind gering, da alle Impfungen noch vor Abreise verabreicht werden und bei manchen Impfungen nur eine Dosis für den zuverlässigen Schutz nötig ist. Für jeden Reisenden sind die Hepatitis A- und die Diphtherie-Tetanus-Impfung empfohlen, für Asien und Afrika auch die Polioimpfung. Bei Reisen >30 Tagen, jüngeren Personen und Reisenden mit Risikoverhalten sollte immer auch eine Hepatitis B-Impfung, eventuell als Kombination mit Hepatitis A in Betracht gezogen werden. Je nach Reisestil, -destination und -dauer können auch weitere Impfungen wie z.B. die Typhus-, Tollwut-, Zeckenenzephalitis-, Grippe-, Masern-Mumps-Röteln-, Gelbfieber-, Meningokokkenmeningitis- und die Japanische Enzephalitis-Impfung in Frage kommen. Mehrere Impfungen können gleichzeitig verabreicht werden – eine Staffelung ist nicht nötig. i BAG Supplementum VI, Stand Juli 2000 «Impfungen für Auslandreisende»; http://www.admin.ch/bag/infekt/prev/reisemed/index.htm; Safetravel http://www.safetravel.ch; Tropimed
