MODELLING OF POLARIZATION PROPERTIES OF COMETARY DUST GRAINS D.A. Semenov and N.V. Voshchinnikov Astronomy Department and Sobolev Astronomical Institute, St. Petersburg University, St. Petersburg, 198504 St. Petersburg­Peterhof, Russia ABSTRACT Observational data for dusty comets are summarized and systemized. The dependence of the linear polariza­ tion on various parameters (the phase angle, wavelength, etc.) is analyzed. ... 1987: Dust in comet P/Halley from Vega observations. ...

ISSN 0021-3640, JETP Letters, 2006, Vol. ... The current­voltage characteristics of junctions are analyzed for temperatures from room temperature to 300 mK. The resistance of individual nanotubes is primarily determined by defects and is too large for applications. The use of the bundles of carbon nanotubes makes it possible to considerably reduce the resistance of the bolometer, which is determined by a small number of conducting tubes with good tunneling contacts with the electrodes. ...

... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (1­22 GHz) spectra obtained on the RATAN­600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...
