Here we compare the optical properties of porous nonspherical particles of two kinds: . ... For each considered value of porosity P, we give first 8 figures on 1 page that show the dependence of the dimesionless extinction (Q ext ) and linear polarization (Q pol ) cross-sections particles on their difraction parameter x v = 2 pi r v / lambda, where r v is the radius of a sphere which volume is equal to that of a nonspherical particle, lambda is the wavelength of incident radiation. ...

... In brief: the frequency-dependent radiative transfer equation is solved for a dust under assumption of spherically-symmetric geometry for its distribution taking into account particle size distribution and quantum heating effects for the very small dust particles. ... Table: Model parameters for IRAS04296+3429. ... parameter . ... hot dust shell) . ... The best fit to the spectral energy distribution of IRAS04296 is shown by heavy solid line (see Table2 for details concerning parameters of the model...

Next: Redshift Distribution Up: Sample Identification Previous: Previously Identified Sources . ... In Figure 3, we plot the redshift distribution of DXRBS FSRQs opposite that of the 1 Jy and S4 samples. In Figure 4, we plot the redshift distribution of DXRBS BL Lacs opposite the Slew and 1 Jy samples. ... The apparent deficit of objects at the very highest luminosities is a result of the smaller area of sky covered by DXRBS compared to, e.g., the Slew and 1 Jy samples. ...

THE PHOTOMETRIC RESEARCHS OF THE MERCURY'S SURFACE BY MEANS OF DIGITAL MODELS. ... The surface brightness of Mercury was measured Danjon (1933, 1949, 1953) and Harris (1961) in phase angle 3o-123o. The analysis of the various data of the integral photometric gives the results of determination of the main photometric constants for Mercury. ... THE PHOTOMETRIC RESEARCHS OF THE MERCURY'S SURFACE: S.G. Pugacheva The surface brightness of the Mercurian images was established on the geologic map Mercury. ...

... A file upload element on an HTML form. ... JavaScript 1.1: added type property . ... The HTML INPUT tag, with "file" as the value of the TYPE attribute. For a given form, the JavaScript runtime engine creates appropriate FileUpload objects and puts these objects in the elements array of the corresponding Form object. ... form . ... For all FileUpload objects, the value of the type property is "file" . ... Use the value property to obtain the file name that the user typed into a FileUpload object. ...

Instrument Summary -- Why Use the GHRS? Here we provide a brief overview of the basic properties of the GHRS. ... The GHRS can obtain spectra from about 1150 to 3200 . ... The repeatability of fluxes is even better, being better than 1%; i.e., it is possible to compare measures of the same wavelength in the same star at different times to within 1% for observations with the LSA. ... The source to be observed may be placed in a Large Science Aperture (LSA) or a Small Science Aperture (SSA). ...

... Obviously, the size of the cavern is of the order of the Schwartzman radius. ... Thus, consideration of the inverse effect of pulsar radiation on the properties of accreting plasma makes the ejection possible even when the Schwartzman radius is smaller than the capture radius. ... If the cavern radius , the condition at its boundary can be written as . ... Apart from magnetic dipole radiation, the cavern may also contain relativistic particles (which are also reflected from the cavern boundary). ...

Homework 6 March 2, 2015 Due on March 13, 2015 This is a simple fit of a straight line to noisy data as in the HW 4 y a + bx = , i i where a and b are the unknown parameters. ... 2) Plot the data and do an "eyeball" estimate (i.e., no fancy mathematical calculations, but explain how you arrived at your answers) of the parameters a, b, nd and . a a b , (3) Use the answers in part (1) to set the initial values of the input parameters. ... 4) Repeat [3] for different values of the step size. ...
