... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

... Routines for accessing I/O ports are in /usr/include/asm/io.h (or linux/include/asm-i386/io.h in the kernel source distribution). ... Before you access any ports, you must give your program permission to do so. This is done by calling the ioperm() function (declared in unistd.h , and defined in the kernel) somewhere near the start of your program (before any I/O port accesses). ... For example, ioperm(0x300, 5, 1) would give access to ports 0x300 through 0x304 (a total of 5 ports). ...

... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...
