Abstract:

Dans ce travail, nous avons étudié la croissance de films d’oxydes Bi2FeCrO6 (BFCO) en utilisant les techniques de sol-gel et dépôt par laser pulsé (PLD). Dans le cas de la voie chimique, des précurseurs en solution ont été préparés, puis déposés par centrifugation sur des substrats de silicium (100) ou de quartz. Les nombreuses analyses structurelles (DRX) et d'imagerie (SEM, TEM) effectuées sur ces films BFCO ont montré que les films sont assez homogènes mais présentent de nombreuses phases parasites qui peuvent être éliminés partiellement par recuit thermique rapide.

Ce travail de thèse a consisté à approfondir la compréhension des propriétés optoélectroniques de films minces ferroélectriques prometteurs à base de Bi2FeCrO6 (BFCO). Pour ce faire, des caractérisations locales ont été réalisées conjointement avec des caractérisations macroscopiques. Une attention particulière a été portée à l’influence des lacunes d’oxygènes sur les propriétés photovoltaïques ferroélectriques. Les films minces de BFCO apparaissent systématiquement comme des semi-conducteurs de type « p », en raison des lacunes de Bi, Fe et Cr. Ces films forment alors une jonction p-n avec un

Abstract:

The present research is about one of the most basic elements of Western music: harmony. Harmony is the study of the simultaneous combination of sounds, the socalled chords, and investigates the myriad possibilities of organizing them. Despite all the number and variety of publications on harmony, there still is an important, not yet bridged gap: publications that originate in the classical music world do not include more or less recent popular repertoire, and publications that originate in the popular music world do not include so many materials that have been long established by the historic

As part of Modern Portfolio Theory, Portfolio management is a subject introduced by Markowitz back in 1950s. In Chapter 1 of this paper, we describe the Mean- Variance portfolio selection model proposed by Markowitz. Since its introduction, this model has been considered as the standard model. Although it has many advantages, with the years passing and the increased complexity of the markets, the model showed all its limits. The main drawbacks arises from the unrealistic assumptions at the base of the model. In other words, the assumptions are not able to present the real world and the risk me

Abstract:

The size reduction of transistors has been the main reason for a successful development of semiconductor integrated circuits over the last decades. Because of the physically limited downscaling of transistors, alternative technologies namely the information processing and nonvolatile resistive switches (also termed memristors) have come into focus. Memristors reveal a fast switching speed, long retention time, and stable endurance. Nonvolatile analog bipolar resistive switching with a considerable large On/Off ratio is reported in BiFeO3 (BFO)-based resistive switches. So far resistive switche

This thesis is concerned with studying the fascinating quantum properties of real-world nanostructures embedded in a noisy condensed matter environment. The interaction with light is used for controlling and manipulating the quantum state of the systems considered here. In some instances, laser pulses also provide a way of actively probing and controlling environmental interactions. The first two research chapters assess two different ways of performing all-optical spin qubit gates in self-assembled quantum dots. The principal conclusion is that an `adiabatic' control technique holds the promi

The thinking that resulted in this thesis has its roots in the first televised images that marked my childhood.

Knowing that Hitler was the ultimate evil, and hearing that Arafat was like Hitler, how could it be wrong to destroy him?

Upon starvation, individual amoebae of D. discoideum cooperate to produce a cell aggregate. The aggregate then elongates into a slug which moves chemotactically towards food sources. Culmination of the developmental cycle results in the formation of a fruiting body containing differentiated stalk and spore cells. Ammonia is produced naturally in the aggregates during starvation and is implicated in the regulation of the developmental cycle. Addition of excess ammonia leads to inhibition of aggregation, increased slug migration, delay of culmination and the promotion of spore formation. This th

Abstract:

Ce mémoire est consacré au développement du concept de l’antenne à résonateur BIE pour la génération de la polarisation circulaire. Deux types d’antenne ont pu être réalisées à l’aide des propriétés isotropes et anisotropes des matériaux BIE. L’excitation d’une matériau BIE isotrope par un patch à encoches a abouti à la réalisation d’une antenne BIE à polarisation circulaire permettant ainsi d’élaborer deux systèmes en polarisation circulaire : l’antenne multifréquences et l’antenne à diversité de polarisation. Un agencement anisotrope combinant un matériau BIE métallique et un polariseur a re

Abstract:

Le droit international privé poursuit deux objectifs généraux : l'un tourné vers l'ordre international en développant sa cohérence et sa fluidité malgré le phénomène de la frontière ; l'autre orienté vers l'ordre interne en assurant sa cohésion et la défense de ses valeurs essentielles. Celles-ci se nourrissent naturellement des droits garantis par la CEDH créant ainsi un risque de déséquilibre de la discipline, l'une seulement de ses finalités bénéficiant d'un renforcement. Pourtant, la discontinuité des ordres juridiques n'est pas à craindre. La CEDH exerce une influence qui dépasse la seule

Abstract:

To produce superior team performances members must be able to work well together to exceed the sum of their parts. Despite an extensive body of research in healthcare, business, military, and aviation, there is limited understanding of what effective teams do in sport. In an attempt to address this gap in the literature the present doctoral thesis - commissioned by the England and Wales Cricket Board (ECB) - sought to uncover, measure, test, and improve the most important factors for team effectiveness in cricket. The thesis contains three empirical studies which address the following research

Abstract:

This thesis presents the results of an investigation into the use of puzzle-based combinatorial structures for erasure correction purposes. The research encompasses two main combinatorial structures: the well-known number placement puzzle Sudoku and a novel three component construction designed specifically with puzzle-based erasure correction in mind. The thesis describes the construction of outline erasure correction schemes incorporating each of the two structures. The research identifies that both of the structures contain a number of smaller sub-structures, the removal of which results in

Abstract:

The boundaries of victimhood have received increasing attention in criminology, particularly considering the recent proliferation in 'trauma talk' or 'trauma creep'. Noting the connections between victims and trauma, there is now increasing recognition of the impact of victimisation, not only on individuals, but upon families, communities and cultures with its effects extending across time, place and person. Following David Garland's assertion of the 'return of the victim' 15 years ago, the interests of victims have moved to centre stage of the criminal justice system with the experiences of s

The study focuses on key events in Iranian history such as the overthrow of the Mossadegh government in 1953, the White Revolution, the Islamic Revolution of 1979, and the Iran-Iraq war. It will be shown that although news and articles were based on selected facts, they still presented a picture of Iran that was at best distorted, the distortions and misrepresentations a

Deep geological disposal in a multibarrier cementitious facility is being developed by a number of countries for the safe, long-term disposal of intermediate-level radioactive wastes. Intermediate-level radioactive waste, which dominates the radioactive waste inventory in the United Kingdom on a volumetric basis, is a heterogeneous wasteform that contains organic materials including cellulosic materials, encased in concrete. Under the alkaline conditions expected in the cementitious geological disposal facility (GDF), these materials will undergo abiotic, chemical hydrolysis, and will produce

Abstract:

Commitment to mitosis is universally regulated by the activation of a protein complex Mitotic Promoting Factor (MPF). Activation of MPF activates the downstream mitotic kinases (e.g. Polo, Aurora and NIMA related kinases) that lead to a number of different mitotic events. As in other systems, the fission yeast Polo kinase, Plo1 regulates diverse mitotic events including mitotic commitment, spindle formation, the cytokinetic ring formation/contraction, and the exit from mitosis. The aim for my project was to use a genetic and biochemical approach to assess the impact of Plo1 upon the compositio

Alzheimer’s Disease (AD) is a devastating neurodegenerative condition with synaptic impairment at the onset of disease. Previously, our group have shown that the p25 molecule is changed in the post mortem brain of mild stage AD patients. A mass spectrometric analysis of p25 transgenic mouse brain provided us with a set of potential p25 downstream molecules. Three of these candidate molecules which had synaptic/dendritic localization – CYFIP2, CYFIP1 and CSPα were selected to be studied in the post-mortem brain of Alzheimer’s patients. CYFIP2 is a dendritically localised molecule with biologica
