System for moving a patient

Charles Baur, Loïc Benoît Tissot-Daguette, Hubert Pierre-Marie Benoît Schneegans, Marine Chantal Elisabeth Geneviève Clogenson

The invention relates to a system (13) for moving a lying patient (P) from a first position to a second position according to a controlled motion comprising a back sheet, a front sheet, each comprising two lateral edges (L1, L2). The system (13) comprises ...

Excitonic absorption and defect-related emission in three-dimensional MoS2 pyramids

Anna Fontcuberta i Morral, Luca Francaviglia, Marco Negri

MoS2 micro-pyramids have demonstrated interesting properties in the fields of photonics and non-linear optics. In this work, we show the excitonic absorption and cathodoluminescence (CL) emission of MoS2 micro-pyramids grown by chemical vapor deposition (C ...

On the Influence of an Elevated Terrain on the Grounding Resistance of a Vertical Rod

Marcos Rubinstein, Antonio Sunjerga

In this paper, we analyze the grounding resistance of a vertical grounding rod located in an elevated terrain. Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to f ...

Abnormal Grain Growth in AlScN Thin Films Induced by Complexion Formation at Crystallite Interfaces

Paul Muralt, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Stefan Mertin, Mohammad Fazel Parsapour Kolour, Vladimir Pashchenko

Sputter deposited Al(1-x)ScxN thin films with a Sc content from x = 0 to 43 at% are investigated by electron microscopy in order to study and explain the formation and growth of abnormally oriented grains (AOG). It is found that the latter did not nucleate ...

Fractal surfaces in adhesive wear processes.

Jean-François Molinari, Enrico Milanese, Ramin Aghababaei, Tobias Brink

Wear of materials plays a key role in the durability of manifactured objects and it has thus an economical importance in our society. In spite of the efforts, a unified picture of the underlying physics of the phenomenon is still far from being reached, be ...

Particle-Based Numerical Manifold Method to Model Dynamic Fracture Process in Rock Blasting

Jian Zhao, Qianbing Zhang, Xing Li

A particle-based numerical manifold method (PNMM) is developed to investigate rock fracturing behavior under dynamic loading. The basic idea of PNMM is to represent the microstructure of rock with a group of particles and to simulate the macroscopic behavi ...

Mechanism and energetics of < c plus a > dislocation cross-slip in hcp metals

William Curtin, Zhaoxuan Wu

Hexagonal close-packed (hcp) metals such as Mg, Ti, and Zr are lightweight and/or durable metals with critical structural applications in the automotive (Mg), aerospace (Ti), and nuclear (Zr) industries. The hcp structure, however, brings significant compl ...
