Tubular gas preconcentrators based on inkjet printed micro-hotplates on foil

Nico de Rooij, Danick Briand, El Hadji Malick Camara

This paper presents the design and implementation of a foil gas preconcentrator (FGP) based on a gold micro-hotplate inkjet printed on a polyimide (PI) substrate. The device is made on flexible foil using printing whereas all preconcentrators seen in liter ...

A new robust oxygen-temperature sensor for aquatic eddy covariance measurements

Alfred Johny Wüest

The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...

Idealized digital models for conical reed instruments, with focus on the internal pressure waveform

Two models for the generation of self-oscillations of reed conical woodwinds are presented. The models use the fewest parameters (of either the resonator or the exciter), whose influence can be quickly explored. The formulation extends iterated maps obtain ...

High bi-atrial organization in patients with long-standing persistent atrial fibrillation terminated within the left atrium

Jean-Marc Vesin, Etienne Pruvot, Andréa Buttu

Sustained atrial fibrillation (AF) is maintained by sites displaying high dominant frequency (DF). In patients (pts) with long-standing persistent AF (LS-pAF), their spatial distribution and the presence of a left-to-right atrial DF gradient remain poorly ...

Interaction of inflammation and hyperoxia in a rat model of neonatal white matter damage

Yohan Van de Looij

Intrauterine infection and inflammation are major reasons for preterm birth. The switch from placenta-mediated to lung-mediated oxygen supply during birth is associated with a sudden rise of tissue oxygen tension that amounts to relative hyperoxia in prete ...

Measurements of eddy correlation oxygen fluxes in shallow freshwaters: Towards routine applications and analysis

Alfred Johny Wüest

Benthic fluxes of dissolved oxygen are measured in a shallow reservoir using the eddy correlation technique. Flux variations depict the diurnal production-consumption cycle, with daytime oxygen release following the solar radiation trend. The average night ...
