Probing aerogels by multiple quantum filtered (131)Xe NMR spectroscopy.

Journal of the American Chemical Society

Meersmann T, Deschamps M, Bodenhausen G.
PMID: 11456628
J Am Chem Soc. 2001 Feb 07;123(5):941-5. doi: 10.1021/ja002747v.

At the interface between solid surfaces and cavities filled with gaseous or liquid xenon, the nuclear magnetization of (131)Xe (S = (3)/(2)) is subject to quadrupolar interactions which may lead to higher rank single-quantum coherences that can be described...

Ultrasound in obstetrics & gynecology : the official journal of the International Society of Ultrasound in Obstetrics and Gynecology

Giacalone PL, Boulot P, Deschamps F, Hedon B, Laffargue F, Viala JL.
PMID: 12796903
Ultrasound Obstet Gynecol. 1993 Jan 01;3(1):48-50. doi: 10.1046/j.1469-0705.1993.03010048.x.

We present a case of prenatal diagnosis of a fetal cystic hygroma of the arm diagnosed using ultrasound scanning in the 32nd week of gestation. This represents the first reported case of cystic hygroma in this location. Ultrasonography was...

Air-flow simulation in realistic models of the trachea.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Deschamps T, Schwartz P, Trebotich D.
PMID: 17271157
Conf Proc IEEE Eng Med Biol Soc. 2004;2004:3933-6. doi: 10.1109/IEMBS.2004.1404099.

In this article we present preliminary results from a new technique for flow simulation in realistic anatomical airways. The airways are extracted by means of Level-Sets methods that accurately model the complex and varying surfaces of anatomical objects. The...

Ultrasonic transient bounded-beam propagation in a solid cylinder waveguide embedded in a solid medium.

The Journal of the Acoustical Society of America

Laguerre L, Grimault A, Deschamps M.
PMID: 17471708
J Acoust Soc Am. 2007 Apr;121(4):1924-34. doi: 10.1121/1.2536759.

A semianalytical solution alternative and complementary to modal technique is presented to predict and interpret the ultrasonic pulsed-bounded-beam propagation in a solid cylinder embedded in a solid matrix. The spectral response to an inside axisymmetric velocity source of longitudinal...

Probabilistic tomography maps chemical heterogeneities throughout the lower mantle.

Science (New York, N.Y.)

Trampert J, Deschamps F, Resovsky J, Yuen D.
PMID: 15514153
Science. 2004 Oct 29;306(5697):853-6. doi: 10.1126/science.1101996.

We obtained likelihoods in the lower mantle for long-wavelength models of bulk sound and shear wave speed, density, and boundary topography, compatible with gravity constraints, from normal mode splitting functions and surface wave data. Taking into account the large...

Single-scan extraction of two-dimensional parameters of infrared focal plane arrays utilizing a Fourier-transform spectrometer.

Applied optics

Rommeluère S, Haïdar R, Guérineau N, Deschamps J, De Borniol E, Million A, Chamonal JP, Destefanis G.
PMID: 17334425
Appl Opt. 2007 Mar 20;46(9):1379-84. doi: 10.1364/ao.46.001379.

We present what is believed to be a novel experimental method to measure the technological parameters (spectral response and quantum yield) of an infrared focal plane array. This method makes original use of a Fourier transform spectrometer, which allows...

Correlation between boson peak and anomalous elastic behavior in GeO2 glass: an in situ Raman scattering study under high-pressure.

The Journal of chemical physics

Deschamps T, Martinet C, de Ligny D, Bruneel JL, Champagnon B.
PMID: 21702563
J Chem Phys. 2011 Jun 21;134(23):234503. doi: 10.1063/1.3599939.

We present low-frequency Raman scattering of pure GeO(2) glass under pressure up to 4 GPa, corresponding to an elastic transformation. Intensity variation and frequency shift of the boson peak are analysed and compared to the Debye model. The decrease...

Cellulase production by trichoderma harzianum in static and mixed solid-state fermentation reactors under nonaseptic conditions.

Biotechnology and bioengineering

Deschamps F, Giuliano C, Asther M, Huet MC, Roussos S.
PMID: 18553830
Biotechnol Bioeng. 1985 Sep;27(9):1385-8. doi: 10.1002/bit.260270917.

Cellulase production from lignocellulosic materials was studied in solid-state cultivation by both static and mixed techniques under nonaseptic conditions. The effects of fermentation conditions, such as moisture content, pH, temperature, and aeration, on cellulase production by Trichoderma harzianum using...

Strain accommodation by slow slip and dyking in a youthful continental rift, East Africa.

Nature

Calais E, d'Oreye N, Albaric J, Deschamps A, Delvaux D, Déverchère J, Ebinger C, Ferdinand RW, Kervyn F, Macheyeki AS, Oyen A, Perrot J, Saria E, Smets B, Stamps DS, Wauthier C.
PMID: 19079058
Nature. 2008 Dec 11;456(7223):783-7. doi: 10.1038/nature07478.

Continental rifts begin and develop through repeated episodes of faulting and magmatism, but strain partitioning between faulting and magmatism during discrete rifting episodes remains poorly documented. In highly evolved rifts, tensile stresses from far-field plate motions accumulate over decades...

Infrared focal plane array with a built-in stationary Fourier-transform spectrometer: basic concepts.

Optics letters

Rommeluère S, Guérineau N, Haidar R, Deschamps J, De Borniol E, Million A, Chamonal JP, Destefanis G.

EPR and DFT studies of the one-electron reduction product of phospholium cations.

Physical chemistry chemical physics : PCCP

Adkine P, Cantat T, Deschamps E, Ricard L, Mézailles N, Le Floch P, Geoffroy M.
PMID: 16482328

Cyclic voltammetry and EPR spectroscopy show that cationic phospholium groups are good electron acceptors whose reduction leads to a neutral radical where the unpaired electron is mainly delocalized on the carbon atoms of the five-membered ring. DFT calculations together...
