Predicting exposure concentrations of chemicals with a wide range of volatility and hydrophobicity in different multi-well plate set-ups

Kristin Schirmer, Julita Maria Stadnicka-Michalak

Quantification of chemical toxicity in small-scale bioassays is challenging owing to small volumes used and extensive analytical resource needs. Yet, relying on nominal concentrations for effect determination maybe erroneous because loss processes can sign ...

Earthquake energy budget

Marie Estelle Solange Violay

Earthquakes occur on planar faults that often mark the boundaries between tectonic plates that collide or slide against each other. During an earthquake, sudden slip on the fault releases elastic energy stored in the earth's crust or upper mantle, resultin ...

Transboundary Headwater Governance in Hindu Kush Himalaya: A Regional Cooperation Framework for Climate Change Adaptation, Water and Food Security and Peace in South Asia

Hindu Kush Himalaya constitutes headwater of some of the largest transboundary basins of planet that sustain one-fourth global population dependent primarily on subsistence agriculture in South Asia. Climate change has stressed hydrological regimes of Hima ...

Fatigue Strength Upgrading of Cover Plate Ends by Welded Extensions in Existing Steel Bridge Girders

Alain Nussbaumer, Dimitrios Lignos, Vasileios Grigoriou

This paper investigates the fatigue upgrading of typical cover plate joint connections in existing steel bridge girders through cover plate extension. The upgraded detail is created by removing the existing transverse end weld, then welding the extension t ...

Influence of heterogeneities on crack propagation

Jean-François Molinari, Okan Yilmaz, Jérémy Bleyer

The influence of material heterogeneities is studied in the context of dynamic failure. We consider a pre-strained plate problem, the homogeneous case of which has been widely studied both experimentally and numerically. This setup is used to isolate the e ...

Acoustic emission source detection and wave generation on a working plate using piezoelectric actuators

Xinchang Liu

In modern automated assembly lines, part feeders play an important role to separate and sort parts. Agility and flexibility are required to achieve a good yield for different types of parts. The common working principle is to vibrate a working plate driven ...

Light filter and method for using such filter

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet

The invention concerns a light filter comprising a plate defined by a length along a direction x, a width along a direction y and a height along a direction z said plate including at least one chamber containing Liquid Crystals (LC) molecules and which is ...

Residual Stress Analysis in AA7449 As-Quenched Thick Plates Using Neutrons and Fe Modelling

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Denis Carron

In the current trend toward thicker aluminium plates, a major concern is the generation of high internal stresses during quenching, which can cause distortions during machining and pose serious safety concerns. Although the material is stretched after quen ...

A multiscale approach to model the anisotropic deformation of lithospheric plates

Roland Logé

The association of experimental data showing that the plastic deformation of olivine, the main constituent of the upper mantle, is highly anisotropic and the ubiquitous seismic anisotropy in the upper mantle, which indicates that olivine crystals show cohe ...

How plate positioning impacts the biomechanics of the open wedge tibial osteotomy; a finite element analysis

Dominique Pioletti, Pierre-Etienne Bourban, Luc Blecha

A numerical model of the medial open wedge tibial osteotomy based on the finite element method was developed. Two plate positions were tested numerically. In a configuration, (a), the plate was fixed in a medial position and (b) in an anteromedial position ...
