See detailA Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation

The dwarf planet Eris is a trans-Neptunian object with an orbital eccentricity of 0.44, an inclination of 44 degrees and a surface composition very similar to that of Pluto. It resides at present at 95.7 astronomical units (1AU is the Earth-Sun distance) from Earth, near its aphelion and more than three times farther than Pluto. Owing to this great distance, measuring its size or detecting a putative atmosphere is difficult. Here we report the observation of a multi-chord stellar occultation by Eris on 6 November 2010 UT. The event is consistent with a spherical shape for Eris, with radius 1,163+/-6kilometres, density 2.52+/-0.05 grams per cm[SUP]3[/SUP] and a high visible geometric albedo, . No nitrogen, argon or methane atmospheres are detected with surface pressure larger than ~1nanobar, about 10,000 times more tenuous than Pluto's present atmosphere. As Pluto's radius is estimated to be between 1,150 and 1,200 kilometres, Eris appears as a Pluto twin, with a bright surface possibly caused by a collapsed atmosphere, owing to its cold environment. We anticipate that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun. [less ▲]

Assisted reproductive treatments (ART) hold an increasing place in the field of female infertility but also of male infertility with the development of new micromanipulative technologies. From January 1985 to December 1997, more than 3,000 ovarian punctures were achieved at the CPMA of the University of Liege and more than 40,000 oocytes were recovered. Global results show a take home baby rate of 23% per ovum pick-up and 27% per embryo transfer. Embryo cryopreservation offers an efficient solution to the problem of supernumerary embryos and opens the way for IVF-derived procedures such as oocyte or embryo donation, surrogate mother. The transfer of frozen-thawed embryos increases the total ongoing pregnancy rate per cycle of 31%. One of the aims of our Centre in the near future is the development of new technologies such as control of chromosomal abnormalities or genetic defect in preimplantation embryos and clinical applications of oocyte or ovarian tissue freezing.

This seminar proposes a detailed overview of the basic management principles that are emerging when managing a SME and, more specifically, a family business. The importance of SMEs in the Belgian economy, the role of the entrepreneur as an indiividual, the role of the family within the firm and key problems emerging in the day-to-day management of the firm are successively discussed.

A new perfectly matched layer (PML) is proposed for convex truncated domains in the context of time-dependent acoustics. With this formulation, the size of the computational domain can be reduced when classical shapes of truncated domains are less appropriate. A numerical discretization based on the discontinuous Galerkin method is then described and validated. An example of realistic three-dimensional application is finally proposed. [less ▲]
