Abstract:
Tartrate stabilization is the process that removes components that contribute to the crystallization of potassium hydrogen tartrate (KHT) and calcium tartrate (CaT) which is an undesirable outcome for wine quality. There are a variety of current tartrate stabilization techniques such as cold stabilization, chemical additives, ion exchange resins, and electrodialysis that stabilize wine, but the most popular being cold stabilization. Cold stabilization requires high amounts of energy and resources to stabilize wine. With the ever increasing demand for more efficient processing, an alternative t

The use of the electronic nose in the wine industry is an emerging technology.

Over a decade after the completion of the human genome, researchers around the world are still wondering what information is hidden in the genome.

As a result of that, the need for recombinantly produced proteins to study protein structure and function is greater than ever.

The effects of varying levels of sulphur dioxide (SO₂) on the cold maceration process was investigated with Pinot noir (Vitis vinifera L.) wine.

Cold maceration is a technique whereby grapes are crushed and placed at low temperatures (4 - lO°C) in the presence 50 - 150 mgL⁻¹ SO₂. This process is believed to provide a medium for the extraction of water soluble phenolic compounds, rather than the alcoholic extraction employed in normal fermentations.

Escherichia coli K12 serves as an important model for studying systems that are important to bacteria in their own right as well as those that are conserved in ‘higher' organisms, which are more difficult and costly to study.

This has led to a rapid expansion of our knowledge of patterns of gene expression and their dependency on growth conditions, cell physiology and individual genes.

Nous avons étudié, dans le cadre de cette thèse, la réalisation de pièces de grandes dimensions du domaine aéronautique en alliage d’aluminium, par technologie WAAM (Wire Arc Additive Manufacturing) robotisée. Cette technologie repose sur l’utilisation un générateur de soudure à l'arc, d’un système de protection gazeuse et d’un système d'alimentation en métal d'a

Abstract:
Studies showed that the ultraviolet irradiation and the cold in woven of plants present some effect on the metabolism of phenolics compounds. The polyphenols are a group of substances present in the wine responsible for causing a series of benefits to the man's health and they are also important in the quality of the wine. The present work was proposed with the objective of comparing wines coming from grapes in wine varieties Cabernet Sauvignon and Chardonnay exposed to cold, ultraviolet irradiation and a subsequent storage, verifying their effects in the quality of wine through physiochemical

Abstract:
A instabilidade tartárica em vinhos brancos ainda é uma preocupação em enologia, existindo várias técnicas para prevenir este problema associado à precipitação dos sais do ácido tartárico. Para além da mais usual, através da utilização do frio, podem ser utilizados aditivos que inibem o processo de formação dos cristais responsáveis pela instabilidade. Com o presente estudo, pretende-se testar um novo aditivo estabilizante, recentemente autorizado, designado por poliaspartato de potássio, na inibição da precipitação dos cristais de ácido tartárico nos vinhos, e comparar a sua eficiência com a

Initially, the thesis considers NATO from an international relations perspective. It then proceeds to examine the institutional evolutionary process of the Alliance since its inception and implementation in 1949. Furthermore, it explores the significance and the meaning of the aforementioned Articles. This thesis utilizes the case study method and refers to four distinct events t

Cette étude aborde l'impact d'un jet sur une plaque plane et sur un obstacle de section carrée. L'objectif de ce travail est l'analyse expérimentale de l'écoulement, et du transfert de chaleur associé, lorsque la surface est chauffée à densité de flux constante. Les mesures de vitesse et de turbulence ont été menées par la Vélocimétrie par Images des Particules (PIV) et l'anémométrie à fil chaud, ce qui a permis la mesure de chaque composante et du champ complet en particulier au voisinage des parois. Différents post-traitements de la PIV ont permis une nette amélioration de l'évaluation des f

Abstract:
This thesis presents methods for fabricating MicroElectroMechanical System (MEMS) actuators and high-flow gas microvalves using wafer-level integration of Shape Memory Alloys (SMAs) in the form of wires and sheets. The work output per volume of SMA actuators exceeds that of other microactuation mechanisms, such as electrostatic, magnetic and piezoelectric actuation, by more than an order of magnitude, making SMA actuators highly promising for applications requiring high forces and large displacements. The use of SMAs in MEMS has so far been limited, partially due to a lack of cost efficient an

The objective of the proposed research is to design, implement, and characterize low-cost, lightweight front-end components and subsystems in the microwave domain through innovative packaging architectures for remote sensing applications. Particular emphasis is placed on system-on-package (SoP) solutions implemented in organic substrates as a low-cost alternative to conventional, expensive, rigid, and fragile radio- frequency substrates. To this end, the dielectric properties of organic substrates RT/duroid 5880, 6002 and 6202 are presented from 30 GHz to 70 GHz, covering most of the Ka and V

Le procédé de soudage Cold Metal Transfer (CMT) est envisagé comme un moyen de réparation additive pour les pièces de grandes dimensions. Cette technologie offre un taux de dépôt élevé avec un apport de chaleur réduit en raison du transfert de matière en régime de court-circuit. Son utilisation permettrait de réduire considérablement les temps d’opération liés à la maintenance, réparation et révision (MRO).

In dieser Arbeit wird das Verhalten von gewickelten Seilen aus Stahllitze unter Zug- und Biegebelastung mit Hilfe der Methode der Finiten Elemente untersucht. Ausgehend von dem Modell einer einfachen Litze mit einem Kern- und sechs Außendrähten erfolgt eine ausführliche Analyse der Spannungsverteilung sowohl bei rein axialer Belastung als auch bei Biegung über eine Seilscheibe. Darauf aufbauend wird das Simulationsmodell schrittweise um komplexere Seilkonstruktionen bis hin zu zweifachen Verseilungen erweitert. Daran schließt sich die Untersuchung der inneren Belastungen bei Einbettung in ein
