Dynamic attending theory (Jones, 1976; Large & Jones, 1999) suggests that isochronously repeating salient points in time are predictable and facilitate processing by synchronizing attentional oscillations in the brain. By manipulating amount and spacing of such salience, this design attempts to enhance accuracy of reproduced melodies. Salience was introduced by dissonant harmonies. All subjects seemed to get distracted by the harsh sound of dissonance. However, non-musicians seemed to benefit from a regular ¾ meter. More research with larger non-musician samples is needed to investigate how dissonance raises cognitive load but may also function as attentional refresher when predictable.

Cancer cells often inhibit the expression of FAS to evade T-cell mediated apoptosis upon HLA-mediated recognition. In this study, we aim to find the prognostic value of FAS expression, next to HLA expression, in colorectal cancer (CRC) patients. Colorectal tissue was immunohistochemically stained for the FAS and HLA receptors. Results show that there are significantly more patients with no FAS and HLA expressions in higher stages corresponding with tumor node metastasis (TNM) than in lower stages. Next to TNM stage, the loss of expression of FAS or of both FAS and HLA turns out to have no additional prognostic value.

Om een ziekte te bestrijden via orale medicatie, moet het actieve farmaceutische bestandsdeel (API) van het gebruikte medicijn oplosbaar zijn in de waterige omgeving van het menselijk lichaam. Bepaalde, dikwijls veelbelovende, API’s zijn echter slecht oplosbaar, wat vaak te wijten is aan de kristalliniteit van het API. In dit project werd de solvent elektrospintechniek aangewend om het kristallijne API in amorfe toestand te brengen als solid dispersion (SD). Uit verschillende analyses bleek dat de wateroplosbaarheid van het medicijn hierdoor drastisch verbetert. Het elektrospinproces is daardoor een potentieel veelbelovende techniek voor de verwerking van doeltreffende API’s in de farmaceutische industrie.

The aim of the present research was twofold. First, we aimed to replicate a recent study by Sharot et al. (2010), which found evidence for the spreading of alternatives (SOA) effect. Second, we investigated the hypothesis that cognitive dissonance, which may explain an existing SOA effect, is accompanied by significant changes in pupil diameter. Our results provide neither support for this hypothesis nor do they replicate the SOA effect. We conclude that more research is needed to investigate the SOA effect and call for deploying more suitable experimental paradigms to investigate the link between cognitive dissonance states and pupillary changes.

Optical components of a gravitational wave (GW) detector must both actively and passively be isolated from microseisms to be able to detect GWs. Active attenuation is achieved by making use of accelerometers within seismic isolation systems. Herein, a characterisation of the internal leg mode resonances of an improved design Folded Pendulum accelerometer, present at the Virgo GW observatory, is being discussed. We model internal leg mode resonances of the accelerometer using Finite Element Method analysis and we experimentally confirm the horizontal in-plane and tilt resonances below 1 kHz, by use of a shadow sensing application combined with Bode plots.

Transparency is generally recognised as an effective policy instrument to increase accountability and fight misconduct. To further our understanding of transparency impact in arms exports, it is thus useful to investigate the EU transparency framework, and analyse the extent member states are adhering to it. This research does it by examining contribution of France, Germany, and the UK to the Annual Reports in relation to their arms exports to the Middle East during 2010-2016. The results indicate that not all studied member states provide full information. Moreover, they intensified export practices despite the growth ofmilitary conflicts in the Middle East.

Vezelversterkte composieten combineren een laag gewicht met zeer goede mechanische eigenschappen en kennen zo vele toepassingen in sectoren waarbij gewichtsbesparing cruciaal is, zoals de luchtvaart-, de ruimtevaart-, de windturbine- of de automobielsector. Typisch komen deze composieten als een gelaagd materiaal: de vezelversterking wordt ingebracht door het stapelen van verschillende lagen, waarna ze geinfuseerd worden met een kunststofmatrix. Ondanks de vele voordelen hebben deze composietlaminaten een groot nadeel omdat de verschillende lagen kunnen loskomen van elkaar, i.e. delaminaties. Dit maakt composieten vooral kwetsbaar voor impact, bv. door steenslag, hagelimpact of contact met werktuigen tijdens onderhoud. In deze studie wordt onderzocht of de impactweerstand van composieten kan verbeterd worden door het inbrengen van taaie nanovezels tussen de vezelversterkingslagen. Er worden 3 verschillende koolstofcomposieten gemaakt; een orthotroop laminaat, een quasi-isotroop laminaat en een laminaat gemaakt uit geweven koolstofvezels. Van elke soort worden steeds samples met en zonder nanovezels bereid. Vervolgens worden de mechanische eigenschappen van een dergelijk composiet met of zonder tussenliggende laag nanovezels bepaald en vergeleken. Hiervoor wordt het composiet onderworpen aan een impacttest, C-scan en een buig- en afschuiftest. Uit deze mechanische beproevingen blijkt dat de mechanische eigenschappen van het composiet niet afnemen bij inbreng van nanovezels in tegenstelling tot andere technieken. Het orthotrope laminaat blijkt het beste resultaat te geven op het gebied van de verbetering van de impactweerstand.

To prevent a further increase in the high prevalence of student burnout, this longitudinal study investigated the influence of sleep quality on burnout. The impact of engaging in university on the development of burnout was assessed in first-year psychology students (N=75) by measuring symptoms before and after their first study period. The hypothesis that a poor sleep quality is associated with higher emotional exhaustion and cynicism and lower professional efficacy was confirmed. Although the change in burnout over time was not predicted by sleep quality, the exposure to academic stressors lead to the development of emotional exhaustion in students.

Autism impacts around 5 million people in the EU (Autism-Europe). Research has shown that social robots, due to their deterministic nature, simplified appearance and technological capabilities, can enable therapy or become assistive technology for empowering autistic individuals with household activities. Consequently, toolkits have emerged for prototyping social robots. Regarding such toolkits, there is a methodological, inclusion gap: there is no comprehensive co-design process to include cognitively disadvantaged users in decision-making regarding robots’ fundamental design choices. To overcome this gap and empower autistic adults to truly design their own (non-preprogrammed) robots, this research explores a social robot toolkit’s well-scaffolded participatory design.

Democratic governance rests on a precarious relationship between the civilian and military branches of government. This relationship is threatened whenever civil-military relations become polarised. This theme is explored through a case study of the French Army during the Algerian War, in which tensions with the de Gaulle government grew as the Army politicised. This culminated in an attempted coup d’etat in 1961 and the rise of the terrorist OAS group. The thesis conducts its analysis through the prism of the guerre revolutionnaire doctrine, which it considers an essential, yet too often overlooked, catalysing factor in the Army’s politicisation.
