Critical review of literature on the use of short implants
Aim The aims of this review were to verify the validity of short implants as a treatment option in patients with partial or total edentulism, having more or less atrophic jawbones. Methods A systematic review of randomized controlled trials (RCT) was conducted, involving also prospective and retrospective studies published in English language between January 2005 and December 2015. The PubMed and Scopus databases were electronically analyzed. Titles and abstracts were selected, and full texts were evaluated. The data were organized in tables and then presented as a narrative analysis. Results The electronic search provided 891 publications, 50 articles were retrieved in full text and only 11 were included in the review. Although the performance of the implants was evaluated through different success and survival criteria, short implants have shown to have a similar performance to longer implants. Conclusions Short implants could be considered as a treatment option comparable to traditional lenght implant. However, other studies must be conducted to assess uniform criteria to state the quality of treatment

Etat des lieux sur l'addiction aux réseaux sociaux en Valais
Dans ce travail de recherche, j’ai traité le phénomène de la cyberdépendance et plus précisément de l’addiction aux réseaux sociaux. Pour ce faire, j’ai procédé de la manière suivante : premièrement, j’ai largement parcouru la documentation existante et traitant de la problématique susmentionnée. Dans un deuxième temps, j’ai ciblé mes recherches sur le terrain en interviewant des professionnels de la prise en charge de ce type de dépendance. Les résultats de mon travail attestent d’une prise de conscience importante de la part des professionnels valaisans durant les dernières années et les moyens mis à leur disposition semblent suffire actuellement pour la prise en charge des cyberdépendances aux réseaux sociaux. Néanmoins, aucune étude ou statistique spécifique à notre canton n’existant encore à ce jour, il est judicieux de nuancer les résultats de mes recherches, ces derniers découlant essentiellement des entretiens que j’ai eus avec les professionnels valaisans des dépendances
Dynamical evolution of active detached binaries on log Jo - log M diagram and contact binary formation
Orbital angular momentum (Jo), systemic mass (M) and orbital period (P)
distributions of chromospherically active binaries (CAB) and W Ursae Majoris (W
UMa) systems were investigated. The diagrams of log Jo - log P, log M - log P
and log Jo-log M were formed from 119 CAB and 102 W UMa stars. The log Jo-log M
diagram is found to be most meaningful in demonstrating dynamical evolution of
binary star orbits. A slightly curved borderline (contact border) separating
the detached and the contact systems was discovered on the log Jo - log M
diagram. Since orbital size (a) and period (P) of binaries are determined by
their current Jo, M and mass ratio q, the rates of orbital angular momentum
loss (dlog Jo/dt) and mass loss (dlog M/dt) are primary parameters to determine
the direction and the speed of the dynamical evolution. A detached system
becomes a contact system if its own dynamical evolution enables it to pass the
contact border on the log Jo - log M diagram. Evolution of q for a mass loosing
detached system is unknown unless mass loss rate for each component is known.
Assuming q is constant in the first approximation and using the mean decreasing
rates of Jo and M from the kinematical ages of CAB stars, it has been predicted
that 11, 23 and 39 cent of current CAB stars would transform to W UMa systems
if their nuclear evolution permits them to live 2, 4 and 6 Gyrs respectively.Comment: 28 pages, including 6 figures and 2 tables, accepted for publication
