Shape model of asteroid (130) Elektra from optical photometry and disk-resolved images from VLT/SPHERE and Nirc2/Keck
Context. Asteroid (130) Elektra belongs to one of the six known triple asteroids in the main belt, so its mass has been reliably determined. Aims. We aim to use all available disk-resolved images of (130) Elektra obtained by the SPHERE instrument at VLT and by the Nirc2 of the Keck telescope together with the disk-integrated photometry to determine its shape model and its size. The volume can b...
متن کاملTreatment of Elektra prosthesis complications
Introduction We have been using the Elektra prosthesis for the treatment of osteoarthritis of the CMC joint of the thumb since 1997. After 760 implantations, we studied 689 cases to obtain sufficient follow-up in 596 women and 93 men. Of the 689 cases with sufficient follow up, only 661 cases were not deceased or had records that could be traced. The results in this series are good in terms of ...
متن کاملThe Elektra Project: Towards a New Learning Experience
Digital game-based learning is a hot topic of research and development. Since the advent of computer and video games, educators were inherently interested in utilizing the beneficial aspects of computer games for educational purposes. These factors are primarily the intrinsic motivation of games, immersive environments, engaging stories, and an artful balance between challenges and continuously...
متن کاملDynamical Outcomes of Planet–planet Scattering
Observations in the past decade have revealed extrasolar planets with a wide range of semi-major axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations. While the protoplanets are embedded in a protoplanetary nebula, dissipation prevents eccentricity growth...
متن کاملPlanet-planet Scattering in Planetesimal Disks
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt. The unstable isolated systems evolve under planet-planet scattering to yield...
