... Content Model: %Body.Content . ... Note that the ID, LANG and CLASS attributes can be used with virtually all of the elements permitted in the document body. ... CLASS . ... The CLASS attribute is most commonly used to attach a different style to some element, but it is recommended that where practical class names should be picked on the basis of the element's semantics, as this will permit other uses, such as restricting search through documents by matching on element class names. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . ... d) The Age of the Chemical Elements . ... Some isotopes (forms of the element with different numbers of neutrons in the nucleus) of these elements are radioactive; they change into other isotopes at a rate that can be measured accurately in the laboratory. ...

A statistical method for the evaluation of the probable amount of interlopers included in the most recently identified asteroid families is developed. ... An application to the most important families listed by Zappal\`a \etal\ {\bf [1995, Icarus in press]} allows to derive the probable amount of interlopers at different size ranges. ... The procedure developed in this paper allows to assess ``how many'' interlopers are probably included in the nominal member lists, but not ``which ones''. ...

... Driver ID: IRIG-AUDIO . ... This driver supports the Inter-Range Instrumentation Group standard time-distribution signal IRIG-B using the audio codec native to the Sun SPARCstation. ... The driver gadget uses a modified BSD audio driver for the Sun SPARCstation which provides a timestamp, raw binary timecode, status byte and decoded ASCII timecode. ... The 100 elements of the IRIG-B timecode are numbered from 0 through 99. ... This driver presently does not use the CF elements. ...

... Identification and Analysis of Binary Star Systems using Probability Theory E. Grocheva and A. Kiselev Photographic Astrometry Department, Pulkovo Observatory, S.Petersburg, 196140, Russia, Email: gl@spb.iomail.lek.ru Abstract. Accurate identification of physical binary star systems has become of increasing interest in recent years. ... We chose 76 double stars from Pulkovo's observation program and calculated the probabilities of a random distribution for these pairs. ...

... The collecting area is increased by nesting concentric mirror pairs, all having the same focal length. ... Figure shows the largest optical element being ground at HDOS. ... X-ray testing demonstrated that the CXO mirrors are indeed the largest high-resolution X-ray optics ever made; the nominal effective area (based on the ground calibrations) is shown as a function of energy in the left panel of Figure , along with those of their Einstein and ROSAT predecessors. ...

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...
