Le présent article se donne pour objectif d’examiner de façon critique les études précédentes sur le passif en Hawsa et de proposer, dans le cadre de lan théorie de l’énonciation de Antoine Culioli, une nouvelle approche. Le passif en Hawsa morphologiquement très simple offre une diversité complexe sur le plan sémantique. Cette complexité de signification ne peut être démêlée et appréhendée que par une approche transcatégorielle qui associe les différents types de procès, l’aspect et le passif dans leur interrelation nécessaire. Cette démarche a d’abord mis en évidence l’impossibilité de dériver le passif de l’actif. En second lieu, elle a permis de distinguer les types de passifs suivants : passif potentiel qui résulte de la combinaison du passif et de l’inaccompli, le passif résultatif obtenu avec l’accompli et qui se subdivise en passif conatif quand le verbe est discret et en passif qualitatif en haut degré avec les verbes denses. En fin, elle a permis de mieux comprendre le fonctionnement de certains verbes qui semblent avoir un comportement à priori singulier y compris le fonctionnement du passif dit « dégénéré » qui s’explique par le double rôle d’agent et d’agi du sujet grammatical.

In the aspect of electric-ship grounding, the time-domain behavior of the ship hull is needed. The grounding scheme impacts the nature of voltage transients during switching events and faults, identifiability and locatability of ground faults, fault current levels, and power quality. Due to the large size of ships compared with the wavelengths of the desired signals, time-domain measurement or simulation is a time-consuming process. Therefore, it is preferred that the behavior be studied in the frequency-domain. In the frequency-domain one can break down the whole ship hull into small blocks and find the frequency behavior of each block (scattering parameters) in a short time and then connect these blocks and find the whole ship hull scattering parameters. Then these scattering pa- rameters should be transferred to the time-domain. The problem with this process is that the measured frequency-domain data (or the simulated data) is band-limited so, while calculating time-domain solutions, due to missing DC and low frequency content the time-domain response encounters causality, passivity and time-delay problems. Despite availability of several software and simulation packets that convert frequency-domain information to time-domain, all are known to suffer from the above mentioned problems. This dissertation provides a solution for computing the Time-Domain Impulse-Response for a system by using its measured or simulated scattering parameters. In this regard, a novel wavelet computational approach is introduced.

<p>This thesis presents an investigation into the structure, composition and performance of naturally formed surface films on AZ alloys as a function of pH and alloyed Al concentration. STEM verified the film structure was bi-layer, consisting of an inner barrier layer, which was visibly deteriorated, and an outer porous layer. EDS SmartMaps™ coupled with the Inca™ software package determined the inner barrier layer was predominantly composed of MgO, whereas the outer layer was primarily Mg(OH)₂. However, both layers appeared to posses mixed oxide/hydroxide components according to ToF-SIMS analysis.</p> <p>Environmental pH had the largest effect on the structure and composition of the surface film. The near-neutral sample showed significant breakdown within the inner layer, which was attributed to natural hydration of MgO to Mg(OH)₂. This favourable hydration reaction is slower in alkaline environments and as such, the stability of the inner barrier layers of the pH 14 samples were noticeably improved. The effect of alloyed Al concentration was less significant however; increased enrichment of Al into the surface film structure appeared to cause a reduction in the thickness of the corrosion film itself.</p> <p>Drastic differences in corrosion performance were observed between the near-neutral and alkaline environments. Significantly better corrosion resistance to anodic dissolution was present in the alkaline environment coupled with a noticeably lower corrosion rate. The absence of breakdown potentials along with the presence of mass transport controlled anodic kinetics signified that the improved stability of the inner barrier layer was responsible for improved corrosion performance. In contrast, severe pitting and a narrow range of anodic stability were present for the near-neutral samples where the inner barrier layer was significantly compromised. This deterioration was deemed responsible for accelerated cathodic kinetics as well as minimal impedance to aggressive Cl^- ions from initiating wide scale electrochemical breakdown of the surface film.</p> / Master of Applied Science (MASc)

It has been shown that people are passive when it comes to political participation in the climate issue. This is despite the fact that the issues related to climate change are growing. Students have been pointed out as a group especially likely to be engaged in the issue but still we haven´t quite seen an emergence of climate movements among students. By interviewing Swedish students, this study sought to reach a better understanding of why it is so. With a theoretical starting position in the models of political participation; Civic Voluntarism Model and Climate Passivity Model the study maps out the explanations of why students are passive in the climate issue. The result of the study shows that there are several different reasons why students choose to be passive. The reasons are based mainly on the difficulty for the students to identify themselves with the issue, problems related to political efficacy and by norms that seem to surround the climate issue.

Organ-ing is a multidisciplinary choreographic project that operates through a set of obscure organs that expand from spaces into bodies and from bodies into spaces. These organs don’t have vital functions and don’t seem to want to be named either; one could absolutely survive without them. Their byproducts are dances, sounds, objects, and poems: a gathering of lovers in lust for touch. Organ-ing is a strategy for a worlding that doesn’t stop at the body's borders. It is realised through an interest in the organ as a form that holds things as well as an ongoing formation. As an organ grows, I learn what it does. The project doesn’t follow linear paths of causality concerning what forms what: these organs shape and are shaped by what they create and hold. While realised and felt inside the human body, they also pour into and out of it. They might be organs of a human but they aren’t human organs. These emergent organs propose a sense of fiction to intertwine with the body’s pre-existing narratives, whether medical or holistic, and bring forth an array of fantasies that weave together the felt sense of the body. The organs of organ-ing don’t mean correcting or questioning what is already there. Instead, they twist or expand mostly pre-existent physical capacities to fabricate a body lustfully entangled with itself and its environment, with the ability and deep desire to belong.
