Повний текст джерелаFluoreszenz-Korrelations-Spektroskopie (FCS) ist eine mächtige Methode, um wichtige physikalische Parameter wie Konzentrationen, Diffusionskoeffizienten, Diffusionsarten oder Bindungsparameter in Lösung und in Modell- oder Zellmembranen zu bestimmen. In nichtidealen Systemen ist FCS fehleranfällig. In dieser Arbeit entwickeln wir mehrere neuartige Realisierungen von FCS, welche diese Fehlerquellen umgehen und die genaue und quantitative Messung dynamischer Parameter in Membranen ermöglichen. Zwei-Fokus FCS mit Kamera-Detektion erlaubt eine genaue und kalibrationsfreie Messung von Diffusionskoeffizienten. Konfokale FCS mit einem Laserscanningmikroskop besitzt eine bislang unerreichte Positionsgenauigkeit, welche uns erstmals dynamische Messungen in Bakterienmembranen mit FCS ermöglichte. Scanning FCS mit einem Scanweg senkrecht zur Membran ermöglicht eine Korrektur von Instabilitäten und damit lange Messzeiten, die zur Bestimmung langsamer Diffusionskoeffizienten notwendig sind. Eine Erweiterung zur kalibrationsfreien Messung von Diffusionskoeffizienten mit Zwei-Fokus Scanning FCS und von Bindungsparametern mit Zwei-Farben Scanning FCS ist einfach. Mit diesen Methoden konnten wir in Systemen messen, die bislang FCS nicht zugänglich waren, so in Hefezellmembranen oder in Membranen lebender Zebrafischembryonen. Line-scan FCS besitzt einen Scanweg parallel zur Membran. Die parallele Messung entlang der ganzen Linie führt zu einer deutlichen Verbesserung der Statistik und damit zu kurzen Messzeiten. Die Kenntnis der Scangeschwindigkeit dient einer internen Kalibration und erlaubt eine akkurate Bestimmung von Diffusionskoeffizienten und Konzentrationen innerhalb weniger Sekunden, kaum beeinflusst vom Bleichen von Fluorophoren. Beide Arten von Scanning FCS können mit einem kommerziellen Laserscanningmikroskop realisiert werden. Häufig kann bei FCS Messungen ein fluoreszierender Hintergrund nicht vermieden werden. Hier ist eine hohe Oberflächenselektivitiät nötig, welche effizient mit einem neuartigen Objektiv erreicht werden kann. Dieses Supercritical Angle-Objektiv erzeugt ein sehr flaches und lateral begrenztes Detektionsvolumen. Eine weitere Methode mit einer ähnlich guten Oberflächenselektivität ist FCS mit Anregung über totale interne Reflektion (TIR-FCS). Bislang war eine quantitative Analyse der TIR-FCS Daten kaum möglich, da keine ausreichend genaue theoretische Beschreibung existierte. In dieser Arbeit entwickeln wir ein akkurates Modell, welches quantitative Messungen mit TIR-FCS erlaubt. Die hier entwickelten neuartgien FCS-Techniken ermöglichen die Untersuchung biologischer Fragestellungen, welche bislang keiner anderen Methode zugänglich sind

Повний текст джерелаThe results obtained during this work concern three fundamental aspects of the phenomenology of the glassy systems: aging, the rejuvenation and the memory effects. We developed original experiments of light scattering with multi-speckle detection on CCD chips. Thanks to these techniques we were able to calculate an ensemble average of the scattered intensity in real time. We study the aging of colloidal Laponite glass by measuring the dynamic structure factor of dilute embedded tracer particles on micrometric length scales. We show that an initial aging regime, where the decay time grows exponentially with aging time is followed by a full aging regime. The dynamics of the tracers is diffusive in the exponential regime and hyperdiffusive in the full aging regime. Besides, we study the aging under a periodic shear of a concentrated suspension of saponite particles. The effects of rejuvenation and the existence of memory effects are discussed there. We observe that the dynamics is fastened by the application of a moderate shear amplitude. Nevertheless, this acceleration does not affect the dynamics of the suspension when the shear is ceased. We show that the dynamics of the suspension at any given time after complete rejuvenation is independent of the shear history before this time as soon as the amplitude of the applied shear is smaller than the characteristic shear necessary to completely rejuvenate the suspension. We thus rule out the existence of a memory effect in our suspension

Повний текст джерелаFluorescence tomography is a preclinical and clinical imaging method which aims to localize fluorescent probes injected into a living organism. In this thesis work, we defined the optimal design and parameters of a continuous wave fluorescent tomograph applied to thin tissue observation. We handled the problem of observing heterogeneous and highly absorbing organs. Secondly, we showed the advantage of time of flight measurement for inclusion detection through thicker tissues. The detection performances of two types of system capable of these measurements were compared and we proposed a protocol to optimize their main parameters. This process was applied to the problematic of prostatic biopsy guiding. It would also be used to detect and localize other pathologies by means of a simple adaptation

Повний текст джерелаThe aim of this work is to propose new identification techniques of thermal diffusivity with the flash method in the case of isotropic and opaque materials. In the first approach, the temperature histories of the two faces of the sample are considered. It is shown that their ratio doesn’t depend on the radial heat diffusion within the sample. In this case, thermal diffusivity can be identified with an adapted moment method. Another way to take the two thermograms into account, is to compute the ratio of their Laplace transforms. Using the quadrupole method, it is shown that the duration of the pulse has no effect. Thermal diffusivity is then identified with the Levenberg-Marquardt method. This technique is particularly suitable for thin films. In the second approach, the logarithmic transform of the rear face temperature rise is considered. In comparison with other existing techniques, the new obtained regression model has the peculiarity to be less sensible to heat losses and to the non-uniformity of the pulse. Furthermore. A stare model is proposed, allowing the identification of thermal diffusivity with the Kalman filter. This technique is also suitable for on-line data redution

Повний текст джерелаBrazil has lived a decade of profund economic crisis during the 80's, which is caracterize by a fall of productive investments, a contained hyperinflation process and the automatisation of the financial spere. This crisi has generated a radical incertainty in the economy and a shortening of the temporal horizon of prevision of the enterprises. This last evolution contradicts the exigences of the productive paradigm of "flexible mass production", which is emerging in the developped economies, as the example of the automobile industry proves it. This new paradigm needs long term engagements of capital by the firms. This contradiction has lead to a truncated modernisation of the firms in brazil, which is caracterized by the integration of the technics rather than the principles of the new paradigm
