We present orbital solutions for three low-amplitude spectroscopic binaries discovered in a sample of 20 solar-type IAU radial-velocity standard stars observed with the Digital Speedometers at the Harvard-Smithsonian Center for Astrophysics. We update the orbital solutions for HD 114762 and HD 140913, and present a preliminary new solution for HD 29587. For all three orbits the minimum mass for...

Distribuţia tensiunilor mecanice ce iau naştere în matricea osoasă după artroplastia de resurfacing a soldului este evaluata cu ajutorul metodei elementelor finite. Modelul computational al segmentului osos implicat a fost construit pe baza imaginilor furnizate de tomografia computerizata post operatorie “in vivo”. Determinarile tensiunilor Von Mises ce apar în matricea osoasa, în cupa iliaca ş...

A Joint Discussion on the extragalactic distance scale and the Hubble constant took place fifteen years ago, at the 1982 XVIIIth General Assembly of the IAU, held in Patras, Greece. At that time, the newest applications of infrared photometers to Tully-Fisher measurements (Aaronson 1983) and Cepheid distances (Madore 1983) were reported. CCDs were just coming into use and had not yet been appli...

While until recently they were often considered as exotic objects of dubious existence, in the last decades there have been overwhelming observational evidences for the presence of stellar mass black holes in binary systems, supermassive black holes at the centers of galaxies, and possibly, intermediate-mass black holes observed as ultraluminous X-ray sources in nearby galaxies. Black holes are...

In this brief proceedings article I summarize the review talk I gave at the IAU 246 meeting in Capri, Italy, glossing over the well-known results from the literature, but paying particular attention to new, previously unpublished material. This new material includes a careful comparison of the apparently contradictory results of two independent methods used to simulate the evolution of binary p...
