Mean field modelling of dynamic and post-dynamic recrystallization during hot deformation of Inconel 718 in the absence of δ phase particles

Roland Logé

Dynamic and post-dynamic recrystallization kinetics were investigated during hot-working of Inconel 718 as a function of temperature,strain and strain rate in the single phase domain.The post-dynamic evolution was found to be extremely fast and impacting s ...

Mechanical and Functional Study of Cell Physiology at the Nanoscale

Pascal Damian Odermatt

By live-cell imaging of biological samples dynamic cellular processes can be resolved. Fluorescence microscopy (FM) and atomic force microscopy (AFM) are both capable of imaging live cells. By combining these techniques structural as well as functional inf ...

A numerical model to reproduce an experimental design to detect strain in cement

Christina Maria Bauer

An experimental set-up consisting of a loading device inserted in a μCT scanner was numerically simulated to predict the strain at the bone-implant interface of the scapula after applying various loading conditions. The aim of the project was to determine ...

Transmission of drug-resistant leprosy in Guinea-Conakry detected by molecular epidemiological approaches

Stewart Cole, Andrej Benjak, Charlotte Avanzi, Philippe Busso, Chloé Marie Loiseau

Molecular drug susceptibility testing was performed on skin biopsies from 24 leprosy patients from Guinea-Conakry for the first time. We identified primary drug resistance in 4 cases and a dapsone-resistant cluster caused by the same strain. Primary transm ...

Strain Management in HTS High Current Cables

Pierluigi Bruzzone, Davide Uglietti, Rainer Wesche

The best performing HTS conductors are available in the form of thin tapes with operating current in the range of 200 A at the operating conditions. To realize conductors with high current carrying capability, in the range of several tens of kA, a large nu ...

Printing low-voltage dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Alexandre Poulin

We demonstrate the fabrication of fully printed thin dielectric elastomer actuators (DEAs), reducing the operation voltage below 300V while keeping good actuation strain. DEAs are soft actuators capable of strains greater than 100% and response times below ...

Monitoring metabolism fluctuations inside a cell culture is a valuable method for assessment of the cells vitality. Enzyme-based biosensors can provide selective measurement of metabolites such as glucose, lactate, glutamate and choline. However, integrati ...

Springer Verlag2015

An overview of the optical methods available to modulate the cellular activity in cell cultures and biological tissues is presented, with a focus on the use of exogenous functional materials that absorb electromagnetic radiation and transduce it into a sec ...

Wiley-Blackwell2014

This research aims to enhance the knowledge on stress–strain states of a coiled pipe used for Hydraulic transient experiments. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an in ...

Integrated biosensors for cell culture monitoring

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo, Cristina Boero

Biosensors for endogenous compounds, such as glucose and lactate, are applied to monitor cell cultures. Cells can be cultivated for several purposes, such as understanding and modeling some biological mechanisms, the development of new drugs and therapies, ...
