This two-part paper presents experimental work to characterize thermal and hydraulic performances of a compact plate heat exchanger. Upward single-phase heat transfer and pressure drop of low pressure, liquid refrigerants R245fa and R236fa was investigated ...

Pergamon-Elsevier Science Ltd2016

In the second article of the present two-part paper, upward single-phase heat transfer within a compact plate heat exchanger was investigated experimentally. The experimental setup, the data reduction technique and pressure drop results were presented in P ...

Deformation of a soft helical filament in an axial flow at low Reynolds number

Pedro Miguel Nunes Pereira de Almeida Reis

We perform a numerical investigation of the deformation of a rotating helical filament subjected to an axial flow, under low Reynolds number conditions, motivated by the propulsion of bacteria using helical flagella. Given its slenderness, the helical rod ...

MECHANICAL SPECTROSCOPY OF ORDERED BINARY Au-Cu

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

We have studied a binary Au-Cu single crystal by mechanical spectroscopy. Upon very slow cooling from high temperatures, additional relaxation peaks arise at lower frequencies in isothermal spectra after the disappearing of the Zener peak below 665 K due t ...

Hydroacoustic Modeling of a Cavitation Vortex Rope for a Francis Turbine

Christian Landry

Hydraulic machines subject to off-design operation involve the presence of cavitating flow regimes in the draft tube. The cavitation vortex rope at part load conditions is described as an excitation source for the hydraulic system, and interactions between ...

EPFL2015

Here we introduce a new pulse sequence for resonance assignment that halves the number of data sets required for sequential linking by directly correlating sequential amide resonances in a single diagonal-free spectrum. The method is demonstrated with both ...

Method for nuclear magnetic resonance (NMR) spectroscopy measurements using long-lived coherences (LLC)

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...

Which prior knowledge? Quantification of in vivo brain (13) C MR spectra following (13) C glucose infusion using AMARES

Rolf Gruetter, Cristina Ramona Cudalbu, Bernard Lanz, João Miguel das Neves Duarte, Nicolas Kunz

The recent developments in high magnetic field (13) C magnetic resonance spectroscopy with improved localization and shimming techniques have led to important gains in sensitivity and spectral resolution of (13) C in vivo spectra in the rodent brain, enabl ...

In Vivo Magnetic Resonance Spectroscopy (MRS) of the Activated Human Brain at 7T

Benoît Schaller

The principal aim of this thesis was to investigate human brain energy metabolism during physiological activation using proton (1H) magnetic resonance spectroscopy (MRS) at 7 Tesla (T). High magnetic fields (≥ 7 T) provide several advantages in human brain ...

Proton and phosphorus magnetic resonance spectroscopy of a mouse model of Alzheimer's disease

Rolf Gruetter, Patrick Aebischer, Bernard Schneider, Cristina Ramona Cudalbu, Hongxia Lei, Sharon Janssens, Lili Sun-Reimer

The development of new diagnostic criteria for Alzheimer's disease (AD) requires new in vivo markers reflecting early pathological changes in the brain of patients. Magnetic resonance (MR) spectroscopy has been shown to provide useful information about the ...
