ON THE NATURE OF ASYMMETRY OF THE LIGHT CURVES OF BM Cas - A LONG PERIOD ECLIPSING SUPERGIANT BINARY
Autor: P. Kalv, V. Harvig, T. Aas, I. Pustylnik
Publikováno v: Odessa Astronomical Publications, Vol 18, Iss 0, Pp 61-64 (2017)
We report results of the analysis of UBVR light curves of the long period eclipsing binary BM Cas obtained between 1967 and 1996 in Tallinn observatory. The asymmetry of the light curves and color variations are discussed and interpreted in terms of

BM Cas – a long-period eclipsing young supergiant binary system in common envelope stage
Autor: I. Pustylnik, V. Harvig, T. Aas, P. Kalv
Publikováno v: Astronomical & Astrophysical Transactions. 26:339-350
We report main results of the analysis of UBVR light curves of the long-period eclipsing binary BM Cas obtained between 1967 and 1996 in Tallinn observatory. The orbital period variations, evolutionary stage, peculiarities of the light curves and col

Dual-Star Photometer at the Tallinn Observatory
Autor: P. Kalv, V. Harvig, I. Pustylnik, T. Aas
Publikováno v: Open Astronomy, Vol 12, Iss 4, Pp 639-641 (2003)
We briefly describe the dual-star photometer designed by P. Kalv, a former director of Tallinn Observatory (1934-2002) for multicolor photometry of close binaries and intrinsic variable stars.

Metoclopramide as a sensitizer of 1,3-bis(2-chloroethyl)-1-nitrosourea treatment of brain tumors in the rat
Autor: Leif G. Salford, Alt T Aas, Arne Brun, Ronald W. Pero
Publikováno v: Anti-Cancer Drugs. 3:267-272
RG2 glioma-like cells grown in in vitro culture can be inoculated into rat brains using stereotactic surgical procedures to produce tumors with a diameter of 12-16 mm2 in 20-21 days. This system has been used to evaluate if metoclopramide (MCA) could

Publikováno v: Proceedings of International Conference on Particle Accelerators.
Tests of the Boeing Average Power Laser Experiment (APLE) injector have demonstrated first-time operation of a photocathode RF gun electron accelerator at 25% duty factor. The multi-alkali photocathode was illuminated by a frequency-doubled mode-lock

Progesterone binding cyst protein in hormone receptor positive breast cancer; a predictive factor for effect of adjuvant tamoxifen treatment
Autor: J A, Søreide, J, Kolnes, A, Skarstein, T, Aas, S, Kvinnsland
Publikováno v: Anticancer research. 14(5B)
Progesterone binding cyst protein (PBCP) was measured in breast cancer cytosols from 128 pre- and post-menopausal women with operable node positive (pN+) breast cancer Stage II. All patients were included in a national multicenter study on the effect
