Abstract:

There are unique challenges in the fabrication and testing of optical semiconductor devices because, unlike typical silicon semiconductor devices, which can be tested cost-effectively on the wafer, many optical devices can only be 'fully' tested once the individual die is bonded to a heat sink. As a result, both the manufacturing process and test strategy need to be capable of predicting yields and product quality attributes based on limited sampling from a batch of the product. The large number of product quality and process variables that are measured for each device when it is manufactured

Abstract:

Nowadays, Ground Source Heat Pumps (GSHPs) are more frequently acting as a main or the only device covering the building heat/cool demand. The most efficient way to extract/dissipate the low-temperature heat from/to the ground is by means of Borehole Heat Exchanger (BHE). In this Master of Science Thesis various aspects related to this technology are studied, focused on summarizing the possibilities of installing this tech-nology in Poland. Borehole drilling methods used in Poland and Sweden are analyzed and the most proper and economical ones according to Polish geological structure are propo

Abstract:

Butylated Hydroxyanisole, BHA, and Butylated Hydroxytoluene, BHT, are commonly used as preservatives for our food as well as additives in many products such as cosmetics, petroleum, and medicine. Although their use has been approved by the Food and Drug Administration (FDA), there have been controversies and debates on whether these phenol derivatives or antioxidants are safe to use. Their accumulative toxicology and side effects need to be thoroughly investigated as we continue to consume them on a daily basis. Data obtained by genomic analysis in Tang lab suggested the involvement of DNA dam

Adenosine and adenosine analogues are recognised as cardioprotective agents due to the responses that they induce through the activation of myocardial adenosine receptors. Antioxidants such as nitroxide radicals have also been found to possess cardioprotective properties in biological systems, namely through their ability to scavenge the oxygen-based free radicals that are potentially damaging to tissues and cells. It was envisaged that the linking of an antioxidant moiety to adenosine would produce an adenosine analogue that activates adenosine receptors and also scavenges oxygen-derived fre

Abstract:

La plupart des médicaments développés pour les maladies du SNC n’atteignent pas leur cible en raison des propriétés uniques de la BHE, nécessitant la mise en place de stratégies de délivrance comme l'utilisation d'un processus physiologique, le RMT. Des peptides ciblant le LDLR (exprimé à la BHE et impliqué dans ces processus) ont été développés. Les objectifs de cette thèse ont été de caractériser le trafic intracellulaire et la capacité de transport de différentes formes de ces peptides dans différents modèles in vitro y compris dans un modèle de BHE.Les résultats obtenus dans une lignée cel

Abstract:

La maladie d’Alzheimer (MA) est la maladie neurodégénérative la plus commune et reste à ce jour incurable. Elle se caractérise par l’accumulation dans le cerveau du peptide neurotoxique bêta-amyloïde (Aβ), par une neuroinflammation et des atteintes neurovasculaires, qui ensemble induisent la mort des neurones et des déficits cognitifs. En raison de leurs activités multiples, les métalloprotéases matricielles (MMPs) émergent comme des acteurs importants dans la MA. Mes travaux ont permis de mieux comprendre l’implication de 3 de ces MMPs dans la MA et soulignent le caractère spécifique et compl

Abstract:

In Ground Source Heat Pump systems (GSHP) a continuous circulation of a fluid inside the exchangers installed in the ground transfers heat between the ground and the buildingâs conditioning system. The heat exchange connected to a GSHP has been shown to alter the natural thermal status of the surrounding subsoil (Banks, 2012). Often the carrier fluids are brines consisting of a mixture of water and anti-freezing solutions, which lower their working temperature in order to improve the heat extraction from the ground during the cold season. The international community has already pointed out t

Abstract:

A model has been developed which simulates a system consisting of a horizontal and vertical ground-coupled heat exchanger connected in parallel to the same heat pump. The model was used in computer simulations to investigate how the annual minimum and mean fluid temperatures at the heat pump varied as several parameters of the combined system were changed. A comparison was also made between different control settings for fluid flow rate distribution between the two exchangers. For the case when the flow rate distribution was not controlled, the effect of viscosity differences between a colder

Abstract:

L’échographie haute résolution est une technique d’imagerie médicale permettant une observation du corps de très bonne définition, à faible profondeur (quelques micromètres). Pour réaliser cela, des ondes ultrasonores sont utilisées (quelques dizaines de mégahertz), produites par l’élément actif de la sonde: un film piézoélectrique. Pour atteindre de telles fréquences, cet élément doit être d’une épaisseur déterminée: de l’ordre de la dizaine de micromètres. Aujourd’hui, le PZT, zirconotitanate de plomb, est le matériau piézoélectrique démontrant les meilleures propriétés pour de telles applic

Dans le monde, une femme sur neuf sera atteinte d’un cancer du sein et environ un tiers développeront alors des métastases, principalement au niveau des poumons, des os et du cerveau. Dans ce dernier cas, le pronostic de survie des patientes est extrêmement faible, et ce, malgré le développement constant de nouvelles molécules anticancéreuses. En effet, la majorité de ces composés sont inefficaces du fait de leur incapacité à franchir la barrière hémato-encéphalique (BHE) pour aller cibler les métastases cérébrales.

Abstract:

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the boreho
