Modeling nitric oxide production and transport in the human lungKerckx, Yannick 09 June 2009 (has links)
Le travail présenté ici porte sur l’étude de la production et du transport du monoxyde d’azote (NO) dans le poumon humain. Le NO est une molécule dont l’implication dans des processus physiologiques n’a été mis en évidence qu’en 1987. Depuis, il a été démontré que le NO joue de nombreux rôles dans le corps humain. Le NO est un gaz labile (instable) dans les conditions physiologiques, il diffuse très facilement au travers des parois et il a une grande affinité pour l’hémoglobine. La production du NO est liée à 3 isoformes différentes de la protéine appelées synthases du NO ou NO synthases.
En 1991, Gustafsson et al. ont découvert du NO endogène (produit par les poumons) dans l’air exhalé chez l’homme et le cochon d’Inde. Depuis près de 15 ans, de plus en plus de groupes de recherche travaillent sur le NO pulmonaire sans s’accorder sur ses rôles exactes. Il est cependant établit que, dans les pathologies comme l’asthme, la production accrue de NO est liée aux processus inflammatoires. Le NO peut être produit par la surface épithéliale (au niveau des conduits pulmonaires) ou alvéolaire, mais les sites exactes de production sont encore débattus.
De part l’impossibilité de mesures directes au-delà des premières générations de l’arbre bronchique, les modèles mathématiques sont indispensables pour interpréter les résultats de mesures de concentrations exhalées et étudier la production et le transport du NO dans le poumon. Récemment, un modèle a été proposé par notre groupe, tenant compte de la convection, de la diffusion moléculaire et de la production du NO dans le poumon.
Le but de ce travail est d’utiliser et d’adapter ce modèle pour reproduire des résultats expérimentaux soit existants, soit originaux.
Dans ce travail, nous montrons que l’augmentation de concentration alvéolaire chez des sujets asthmatiques bien contrôlés est liée à une augmentation de production dans les conduits et non dans les alvéoles. Nous montrons également que, sur base de résultats expérimentaux, la production bronchique dans le poumon des sujets sains doit être très hétérogène pour reproduire des résultats expérimentaux apparemment irréconciliables. Nous montrons enfin que la localisation des conduits pulmonaires subissant une constriction influence la chute de NO exhalé mesurée après cette constriction.
Nous avons également participé à 2 expériences liées à la gravité qui constitueront le matériel susceptible de faire évoluer le modèle.

Characterization of Titanium Silicon Oxide Prepared by Liquid Phase DepositionChang, Chih-te 26 July 2007 (has links)
When the size of display panel increased, the RC delay of TFTs became serious.In order to solve this problem, it is necessary to incorporate a high dielectric (high-k) material used as the gate oxide can increase the gate oxide capacitance Co, which can induce a higher drain current and higher aperture ratio.
In this study, titanium silicon oxide films were grown on amorphous silicon and poly-crystal silicon by liquid phase deposition, the addition of NH4OH in the growth solution can control the PH value and prevent the amorphous and poly-crystalline silicon over etching by HF.
The physical and chemical properties of titanium silicon oxide film by means of several measuring instruments, including Fourier transform infrared spectrometer (FTIR), and X-Ray diffractometer (XRD). An Al/titanium silicon oxide/a-Si or poly-Si/Si metal-oxide-semiconductor (MOS) capacitor structure was used for the electrical measurements. After oxygen and nitrogen annealing, the leakage current is improved due to the reduction of the oxygen vacancy of titanium silicon oxide film. However, the electrical characteristics can be further improved by the postmetallization annealing treatment especially under the negative electric field.
Post-metallization annealing (PMA) is to use the reaction between the aluminum contact and hydroxyl groups existed on oxide surface to form active hydrogen and diffuse through the oxide to passivate the oxide traps. Therefore, titanium silicon oxide
film which treated by PMA with higher dielectric constant and lower leakage current can be obtained.

Fabrication of Large Area Anodic Alumina Oxide (AAO) Arrays and Its ApplicationsYang, Kun-lin 30 July 2007 (has links)
The AAO membrane with nanopore arrays were fabricated by anodizing highly pure aluminum foils (99.9995%) in electrolyte. Ordered array have been obtained under optimized anodizing condition, and pore diameter can be controlled by different anodic voltage and electrolyte. After we got such an ordered arrangement porous alumina array, the following analysis of the material optical properties were characterized. Photoluminescence measurements showed a strong PL peak in blue. The PL peak was 420nm excited by He-Cd laser. From the transmittance spectra, the results showed that material was transparent above 400nm. The XRD spectra of AAO without and with annealing, both showed the diffraction peaks of (311)¡B(400)¡B(440), corresponding to the £^-Al2O3 phase appear.
High ordered anodic porous alumina with holes interval 65nm was prepared in mixture solution of H3PO4 and H2SO4 under high temperature and high concentration. Through the use of porous anodic alumina masks, nanopore arrays were fabricated on Si¡BGaAs substrates by reactive ion etching. Also, metal nanodot arrays were formed through the AAO mask by evaporation. Thin AAO slabs also enhance the light extraction from the QDs, and control the PL emission wavelength.
