LIF is a sensitive probe for minority species which are important for the chemistry of the flame. Unfortunately there are a good many of disadvantages, too. Difficult choice of excitation and detection wavelengths. Tunable UV Lasers are complex in construction and somewhat tricky to operate. And they are not cheap. More interesting minority species have a very low concentration and therefore are not easily detected despite the high sensitivity of the method. The images correspond in...

Ces propriétés sont nécessaires lorsque la taille des objets étudiés est plus petite que la longueur d'onde mise en jeu. Nous désirons une méthode flexible, rapide, précise, non invasive, et unifiée d'excitation et d'analyse. Celle-ci doit être applicable tant dans le domaine des vibrations dans les structures que dans le domaine des ondes acoustiques tridimensionnelles. Pour cela, nous nous basons sur la technique du puits à retournement temporel, qui n'a, à ce jour, été mise en oeuvre que pour la... Infos PDF : 1/12/2008 - 270 p. - 11.99 Mo - Version HTML

Level-0 in Figure 1 corresponds to the case where the currents are synthesized by M 0 Rao-Wilton-Glisson (RWG) basis functions [28]. The associated matrix equation that needs to be solved reads Z[0]I[0] = V[0] , (1) transpose, and V[0] is the excitation vector. In the following, we will assume that the matrix equation is very large and cannot be solved through standard Gaussian-elimination techniques. For perfectly conducting sheets, and when Galerkin’s scheme is used for testing the electric-field integral equation through a symmetric product,...

Experimental results with the laser source and receiver on epicenter demonstrate that the zero-group velocity resonance generated with a low-power modulated excitation source can be detected using a Michelson interferometer coupled to a lock-in amplifier. This resonance peak is sensitive to the thickness and mechanical properties of plates and may be suitable, for example, for the measurement and mapping of nanoscale thickness variations. © 2005 American...

Dans un cristal de YAG, faiblement concentré en ions Tm3+ par exemple, le rapport inh/ h atteint 105 à la température de 5 K. Si un laser monochromatique éclaire le matériau à la fréquence 0, seuls sont excités les ions situés à moins de h de 0. L'excitation des ions autour de 0 se traduit par une réduction de l'absorption, c'est-à-dire par le creusement d'un trou dans le profil d'absorption. C'est le phénomène de hole burning spectral. La largeur du trou atteint 2 h à faible exposition. Par émission spontanée radiative ou par transfert d'énergie vers... Infos PDF : 1/10/2007 - 5 p. - 1.92 Mo - Version HTML

Most researchers of aggression agree that severe aggressive and violent behavior seldom occurs unless there is a convergence of multiple predisposing and precipitating factors such as neurophysiological abnormalities, poor child rearing...

The fluorescence of the yellow fluorescent protein (YFP) donor after excitation of the CFP acceptor was the same for the two internal CLIP170 FRET sensors. Deletion of the last ï¬�ve residues of CLIP170 reduced the FRET signal in both sensors (Fig. 6b and data not shown).
