Separation of blood microsamples by exploiting sedimentation at the microscale

Microsample analysis is highly bene cial in blood-based testing where cutting-edge bioanalytical technologies enable the analysis of volumes down to a few tens of microliters. Despite the availability of analytical methods, the di culty in obtaining high-q ...

Microdevice for Sedimentation-based Separation of Blood Microsamples at the Point of Collection

David Forchelet

Laboratory blood testing plays a central role in current diagnostics and therapeutical decisions. Thus, errors have a direct impact on care quality and cost. The majority of errors occur in the pre-analytical phase, when samples are collected, stored and p ...

Numerical study on the suitability of centrifuge testing for capturing the thermal-induced mechanical behavior of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria, Alice Di Donna

Currently, the suitability of centrifuge testing for capturing the thermal-induced mechanical behavior of full-scale energy piles has not been established, yet, despite their increasing worldwide development. Looking at this challenge, this paper investiga ...

Centrifuge modelling of heating effects on energy pile performance in saturated sand

Lyesse Laloui, Chao Shi

The operation of energy pile in summer can expel excessive heat of the buildings into the ground by the use of a heat pump. Despite of having been implemented for decades, the design of energy pile still relies heavily on empiricism as there is still limit ...

Predicting the axial capacity of piles in sand

Lyesse Laloui, Jean-Marie Fuerbringer, Alessandro Francesco Rotta Loria, Alberto Minardi, Luis Felipe Orellana Espinoza

Currently, although several tools have been proposed for the numerical modelling of the pile-soil interface, there is not a well-established framework concerning the quantitative impact that different estimations of the mechanical properties of this settin ...

Flow simulation and hemolysis modeling for a blood centrifuge device

Mark Sawley, Michel Deville, Patric Hagmann

A common blood separation technique is to accelerate the sedimentation of blood constituents by centrifugation and then collect these constituents separately. When subjected to conditions of excessive stress, hemolysis can however occur, whereby the membra ...

Sedimentation of macroscopic rigid knots and its relation to gel electrophoretic mobility of DNA knots

Giovanni Dietler, Cédric Weber, Andrzej Stasiak, Mathias Carlen

We address the general question of the extent to which the hydrodynamic behaviour of microscopic freely fluctuating objects can be reproduced by macrosopic rigid objects. In particular, we compare the sedimentation speeds of knotted DNA molecules undergoin ...
