0.1-0.3 M sun yr-1, and calibrations of SFRs based on L(70) and L(160) are proposed. Below those two luminosity limits, the relation between SFR and 70 ЮМm (160 ЮМm) luminosity is nonlinear and SFR calibrations become problematic. ... We interpret this increasing dispersion as an effect of the increasing contribution to the infrared emission of dust heated by stellar populations not associated with the current star formation. ...

... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

Data-Analysis-with-SAS in a simple and standardised way, and should allow calibration experts to re-assess the reliability of the different elements of XMM-Newton simulations. ... Also, a release of all calibration files to be used in the reduction, through the SAS, of SciSim generated data, is coordinated with this release. ... Furthermore, two SAS tasks (odffix and epicproc) had to be updated to make possible a proper SAS data reduction of simulated data. ...

Next: Star Formation Rate and Up: No Title Previous: Calculation of Evolutionary Tracks . To start calculations, we choose the distributions of the initial binary parameters: the mass of the primary ZAMS component, , binary mass ratio, , orbital separation a . ... whereas the mass ratio distribution is not. ... The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

... 7.1 Introduction to media types . ... 7.3 Recognized media types . 7.3.1 Media groups One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'cue-before' property for aural user agents). ... For example, the 'font-size' property is useful both for screen and print media. ...

Observation and modelling of main sequence star chromospheres. ... We compare our calculations to recent high res­ olution observations for selected stars in a narrow spectral range ((R­I) џ =0.875\Sigma0.05); we show that Hff line profiles behave as expected, with a tight correlation be­ tween the line width and equivalent width. ... We show that the hydrogen series dominate the radiative cooling in the spectral lines (form 40% to 90%) for Hff emission line stars. ...

Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...
