Abstract (sommario):

La cavéoline est l'un des principaux composants protéiques des cavéoles, qui sont de petites invaginations en forme de coupe dans la membrane plasmique. Il est synthétisé dans le réticulum endoplasmique d'une manière dépendante des particules de reconnaissance du signal et transporté vers l'appareil de Golgi via des vésicules recouvertes de COPII. Au niveau du réseau trans-Golgi (TGN), les complexes de cavéoline 8S s'oligomérisent davantage en complexes 70S avec la facilitation du cholestérol. Ils sont ensuite triés dans des transporteurs par un mécanisme inconnu et transportés vers la membran

Abstract (sommario):

The bulge forming process is a method for shaping tubular components using an internal hydrostatic pressure combined with a compressive axial load. Initial investigations involved carrying out an extensive literature survey to determine the components which could be formed and the effects of using lubricants and different tube materials. Die-blocks were designed to produce tee pieces, cross joints and off-set joints, and electronic on-line instrumentation was incorporated so that the forming pressures and loads could be accurately monitored. A series of tests were carried out in the forming of

Abstract (sommario):

A major aim of current astrophysical research is the development of models of galaxy formation that are consistent with observational data. Until recently, the main tools of such research were broadband colours. However, the Lick system of indices has recently provided researchers with a more accurate tool for probing galaxy populations. The work in this thesis compares Lick indices in bright elliptical galaxies with those in the bulges of spiral galaxies, in an effort to compare, contrast and constrain their star formation histories.

Abstract (sommario):

In this thesis, we investigate the internal kinematics and stellar populations of a subsample of the bulges of nearby galaxies defined by Balcells & Peletier (1994). To do that we have analysed minor axis spectroscopic data of the sample together with Integral Field observations of one the most interesting galaxies in it (NGC7332). We introduce, for the first time, the use of single-burst stellar population models to obtain stellar velocities, velocity dispersions and higher order Gauss-Hermite moments (h_3, h_4) from galaxy spectra in the near-infrared Ca II triplet region. We detect small-am

2006/2007<br>In this thesis I develop a chemical evolution model which takes advantage of the most recent high-quality abundance observations in the Galactic bulge to put constraints on its formation and evolution and to obtain a baseline model for bulges in general. I adopt updated massive star nucleosynthesis and follow the evolution of several alpha-elements and Fe by varying the evolutionary parameters. The [alpha/Fe] ratios in the bulge are correctly predicted to be supersolar for a wide range in [Fe/H], and the stellar metallicity distribution is reproduced assuming a short formation tim

Dans le cas des turbines de basse chute de type bulbe, les pertes de charge dans l’aspirateur influencent fortement le rendement global de la centrale. La prédiction correcte de ces pertes de charge au cours du dimensionnement de la turbine représente donc un enjeu majeur. La prédiction numérique des pertes de charge dans l

Abstract (sommario):

We examine a sample of 1495 galaxies in the UDS/CANDELS field to determine the evolution of two component galaxies, including bulges and discs, within massive galaxies at the epoch 1 < z < 3 when the Hubble sequence forms. We fit all of our galaxies’ light profiles with a single Sérsic fit, as well as with a combination of exponential and Sérsic profiles. The latter is done in order to describe a galaxy with an inner and an outer component, or bulge and disc component. We develop and use three classification methods (visual, F-test and the RFF) to separate our sample into 1-component galaxies

Abstract (sommario):

The question whether the observed properties of galaxies are imprinted by the initial conditions of their formation or determined by different evolutionary processes is still open. In the local Universe, more than 60% of stars reside in elliptical galaxies and bulges of lenticular and spiral galaxies. Thus, unveiling the paths of bulge formation and evolution ensures a better understanding of galaxies themselves. The current paradigm separates galactic bulges into two broad categories, namely classical and disk-like bulges. In this scenario, we focus on the description of the bulge component i

Abstract (sommario):

There is mounting evidence that supermassive black holes (SMBHs) form and grow in bulgeless galaxies. However, a robust determination of the fraction of active galactic nuclei (AGNs) in bulgeless galaxies, an important constraint to models of SMBH seed formation and merger-free models of AGN fueling, is unknown, since optical studies have been shown to be incomplete for AGNs in low-mass galaxies. In a recent study using the Wide-field Infrared Survey Explorer, we discovered hundreds of bulgeless galaxies that display mid-infrared signatures of extremely hot dust suggestive of powerful accretin

Abstract (sommario):

Spiral galaxies contain large amounts of interstellar dust, that absorbs and scatters their photons. This results in strong distortions and changes of their observed stellar images from what would be observed in the absence of the dust. Because of this the measured structural parameters of spiral galaxies, and indeed, knowledge of some of the most fundamental physical attributes of galaxies - their stellar distributions - is strongly biased. I present here the results of a study to quantify the effects of dust on the derived photometric parameters of disks (old stellar disks and young stellar

For both samples, sigma(star) is determined via two different methods that are popular in the literature, and we provide fits for each sample based on both sets of sigma(star). We find the fit to the active galactic nucleus sample is shallower than the fit to the quiescent galaxy sample, and that the slope

Abstract (sommario):

Zr-2.5 wt % Nb (Zr-2.5Nb) is the main alloy used in the pressure tubes of CANDU nuclear reactors, which are manufactured by hot extrusion. Pressure tubes are subjected to high irradiation fields and corrosion, in addition to the applied stress at operating temperatures of around 330°C, which leads to irradiation creep that is often life-limiting; re-tubing the reactors, is a source of significant through-life cost of the reactor system. However, significant variability in performance is observed between tubes and stations, which is felt to be due to variability in the fabrication and operation

Abstract (sommario):

If form follows normative discourse in medical design, what happens to the gestalt when you include related discourses of the medical ventilator in the design process? My aim has been to integrate critical industrial design and with an exploratory aesthetic approach. This aesthetic approach aimed to create an on going exchange between the development of concepts inspired by theory and the creative sketching of 3-D form.The medical ventilator can be divided in three parts: 1. The technical part of the machine, 2. The monitor with an interface, and 3. The tubes that is the connection to the pati

Abstract (sommario):

Doctor of Philosophy<br>Department of Mechanical and Nuclear Engineering<br>Steven J. Eckels<br>The current research presents the experimental investigation of the effect of tube pitch on enhanced tube bundles’ performance. The typical application of this research is flooded refrigerant evaporators. Boosting evaporator’s performance through optimizing tube spacing reduces cost and energy consumption. R-134a with the enhanced tube Turbo BII-HP and R-123 with Turbo BII-LP were used in this study. Three tube pitches were tested P/D 1.167, P/D 1.33, and P/D 1.5. Each tube bundle includes 20 tubes

Abstract (sommario):

Problems with the identification of tubular fossils from ancient hydrothermal vent and cold seep deposits have hindered understanding of the evolutionary history of vent and seep communities. This thesis aims to (1) improve knowledge of lesser-studied tubicolous annelids occupying vents and seeps, (2) study the diversity of tubes at vents and seeps, (3) investigate the fossilisation of tubes within modern vents and seeps, (4) better interpret the fossil record, and (5) provide insights into the palaeoecology these environments. Results presented here on investigations of Sclerolinum contortum,

Abstract (sommario):

The diploma thesis is focused on the analysis of the behavior of the thin-walled tubular test specimen during the technological test of the liquid draining of the tubes. The test specimen ‘in the form a tube was made of austenitic stainless steel 17 240 (1.4301, X5CrNi18-10). During the experiment, the radial expanding tool was quasi-statically charged by the internal fluid pressure. In the introductory part, the thesis focuses on the stress-strain description of the method of tube bulging and possible ways of detecting the strain of material during forming. The experimental part is primarily
