Previous issue date: 2012-03-20O princ?pio da igualdade, norma fundamental do Estado Social Democr?tico brasileiro, assume especial relevo quando se analisa o modelo de distribui??o de benef?cios previdenci?rios em fun??o do g?nero. A realiza??o do direito ? previd?ncia social, direito fundamental de segunda dimens?o, deve orientar-se pela isonomia no acesso aos bens jur?dicos, com vistas ? maior concretiza??o poss?vel. A m?xima j? h? muito preconizada de tratar igualmente os iguais e, em consequ?ncia, desigualmente os desiguais exige, na perspectiva material do aludido postulado, que se afira a adequa??o do modelo atual de concess?o de benef?cios previdenci?rios afetados pelo g?nero. As esp?cies previdenci?rias em quest?o - aposentadoria por tempo de contribui??o e aposentadoria por idade - diferenciam homens e mulheres para a sua frui??o, demandando, em s?ntese, trinta e cinco anos de tempo de contribui??o para homens e trinta para mulheres, ou sessenta e cinco anos de idade para homens e sessenta anos para mulheres. Nesse desiderato anal?tico, diversos fatores hist?rico-sociol?gicos e jur?dicos (quer sob o vi?s doutrin?rio, jurisprudencial ou puramente normativo) devem ser sopesados, examinando as mudan?as de paradigma em rela??o ? participa??o e ? integra??o da mulher ?s mais diversas fun??es sociais e conduzindo a um cen?rio de composi??o da igualdade previdenci?ria. As vari?veis demonstram, em ?ltima an?lise, a impropriedade do quadro atual e a consequente disparidade na outorga das aposentadorias a homens e mulheres, segurados do regime geral de previd?ncia social. O crit?rio orientador de qualquer modifica??o no sistema deve convergir para a origem comum do direito envolvido e assumir como norte a raz?o de ser dos direitos fundamentais: a pessoa como valor fundamental, independentemente de sexo ou g?nero. Considerando, ent?o, a experi?ncia da legisla??o anterior a 1991, a possibilidade de recrudescimento das exig?ncias legais, a representatividade econ?mica, a participa??o dessas duas esp?cies de benef?cios no contexto do regime geral de previd?ncia, bem como todas as demais condicionantes que atuam sobre esse direito (? aposentadoria) em forma??o, algumas altera??es normativas podem ser propostas. As sugest?es principiam com a redu??o da idade ou do tempo de contribui??o para homens, perpassam pela majora??o desses requisitos para mulheres e mesclam redu??o para homens com majora??o para mulheres at? o termo m?dio. Prosseguem tamb?m com a formula??o de tabelas de transi??o para a minora??o dos impactos ?s popula??es atingidas, contemplando ainda a eleva??o dos atuais limites de idade e de tempo de contribui??o e facultando, ao final, a aplica??o das novas regras apenas para novos segurados.

Full textAbstract:
Over the last decade Laptop Orchestras and Mobile Ensembles have proliferated.
As a result, a large body of research has arisen on infrastructure, evaluation, design
principles and compositional methodologies for Computer Music Ensembles
(CME).
However, little has been addressed and very little is known about the challenges
and opportunities provided by CMEs for creativity in musical performance.
Therefore, one of the most common issues CMEs have to deal with is the lack of
a systematic approach to handle the implications of the performative paradigms
they seek to explore, in terms of their creative constraints and affordances.
This is the challenging goal this thesis addresses, and for attaining so it first
seeks to find a common ground in the strategies developed for assessing creativity
in different performative setups, for later proposing an informed pathway for
performative engagement in CMEs.
Our research combines an exploratory stage and an experimental stage. The
exploratory stage was informed by out artistic praxis with our own CME, the
Barcelona Laptop Orchestra. Through the study of the multi-user instruments developed
over the past years, we identified the creative constraints and affordances
provided by different performative paradigms. Informed by the findings provided
by our artistic research, the experimental stage addressed the study of musical
creativity through the performance analysis on specifically designed multi-user
instruments. For such purpose we proposed a novel computational methodology
to evaluate the creative content of a musical performance.
Two experiments were conducted to incorporate our computational methodology
into ecologically valid scenarios, aimed at a better understanding of the
relationship between topologies of interdependence and creative outcome. For
both experiments, we captured performance data from ensemble improvisations,
from where the creativity metrics were then computed. As a preliminary step,
we investigated the performative engagement and sharing of musical ideations in
an ensemble scenario. In a further step, we computed the creativity attributes to
comparatively evaluate performances under different scenarios.
The findings provided quantitative evidence of the differences between musical
creativity in individual, ensemble and interdependent scenarios. Additionally,
the findings point out what strategies performers adopt to best keep their own musical
voice in interdependence scenarios, and what novel creative behaviors may
be promoted through new topologies of interdependence. Our findings shed light
on the nature of performers’ creative behavior with interdependent multi-user instruments,
and show that the introduced methodology can have applications in the
broader context of analysis of creativity in musical performance.Durant la darrera d`ecada les Laptop Orchestras i els Mobile Ensembles han proliferat arreu. Com a conseq¨u`encia d’aix`o, ha aparegut un volum considerable de recerca al voltant de la infraestructura, l’avaluaci´o, els principis de disseny i les metodologies composicionals per ensembles de computadors (CMEs). Tanmateix, poc coneixem dels reptes i oportunitats que els CMEs ens ofereixen respecte de la creativitat en la pr`actica musical. En conseq¨u`encia, un dels reptes que la majoria de CMEs han d’encarar ´es la manca d’una estrat`egia sistem` atica per preveure i abordar les implicacions dels paradigmes performatius a explorar, respecte de les seves limitacions i possibilitats creatives. Aquest ´es el repte que adrecem en aquesta tesi, i per assolir-lo primer tractem d’establir un denominador com´u en les estrat`egies desenvolupades per avaluar la creativitat en diversos entorns performatius, per despr´es proposar un itinerari que permeti assolir una adequada involucraci´o creativa en els CMEs. La nostra recerca ha combinat una fase explorat`oria i una d’experimental. La fase explorat`oria s’ha fonamentat en la praxi art´ıstica duta a terme en el nostre propi CME, la Barcelona Laptop Orchestra. A trav´es de l’estudi dels instruments multi-usuari desenvolupats durant els darrers anys, hem identificat les potencialitats i restriccions presents en diversos paradigmes performatius. Basats en els resultats de la nostra recerca art´ıstica, la fase experimental s’ha centrat en l’estudi de la creativitat musical a trav´es de l’an`alisi interpretatiu en instruments multiusuari desenvolupats a tal efecte. A tal fi, hem proposat una nova metodologia computacional per avaluar el contingut creatiu d’una execuci´o musical. Hem dut a terme dos experiments incorporant la nostra m`etrica en escenaris realistes, a fi de comprendre millor la relaci´o entre topologies d’interdepend`encia i resultat creatiu. Per ambd´os experiments, hem recollit informaci´o d’improvisacions en grup, d’on hem calculat les m`etriques de creativitat. Com a pas previ, hem investigat en grau d’involucraci´o i la compartici´o d’ideacions musicals en escenaris col lectius. Tot seguit, hem calculat els atributs de creativitat per comparar execucions musicals en diferents escenaris. Els resultats proporcionen una evid`encia quantitativa de la difer`encia entre la creativitat musical en escenaris d’execuci´o musical individual, en grup i interdependent. Addicionalment, ens il lustren quines estrat`egies adopten els m´usics per mantenir la seva pr`opia individualitat musical en escenaris d’interdepend`encia, i quins nous comportaments creatius podem promoure a trav´es de noves topologies d’interdepend`encia. Els resultats obtinguts aporten nova llum en la natura del comportament creatiu dels m´usics amb instruments multi-usuari interdependents, i mostren que la metodologia presentada pot tenir aplicacions en el context m´es ampli de l’an`alisi de la creativitat musical en l’execuci´o musical.

Vår kandidatarbetstid har resulterat i nio stycken småfilmer som är till för att ge mer information om BTH och regionen för nyfikna. Fyra av dessa filmer innerhåller lite mer information om region, boende/kommunikationer, skolan och det studiesociala. Syftet med dessa fyra filmer är att blanda in BTH på olika sätt, att man sätter skolan som en röd tråd även i region och bostadsfrågorna. Vi gjorde även fyra stycken studentintervjuer, för att visa vad nuvarande studenter tycker om bostadsmöjligheterna och det studiesociala mm. Vi ville även visa att det finns folk från Kiruna i norr till Lund i Söder, som går på skolan, och att det finns många olika typer av människor som du får möjlighet att lära känna om du börjar studera här. Det blir variation och man tar till sig det som sägs på ett annat sätt, än i de mer traditionella informationsfilmerna. Sist men inte minst så gjorde vi en mässfilm som innehåller bilder och ord från de fyra informationsfilmerna, och som ska fånga upp ett intresse på kort tid. I den här mässfilmen har vi även inkluderat en showreel som visar några utav de projekt som har gjorts av studenter på BTH.Our work with the Bachelors thesis has resulted in nine short informational movies which have as a purpose to give information about BTH ( Blekinge Institute of Technology ), and the region to interested people. Four of these movies include information on the region, living/transportation, the school and the social amenities provided for the students. We have also made four movies about different students from BTH. We want to show that there are students from Kiruna in the north to Lund in the south, and that there are many different kinds of people you can meet when you begin your time as a student here. Due to the fact that there are nine different movies there will be variation, and you will accept the information in a better way than in traditional informational movies. Last but not least, we made an event movie which does not include a speaker text but instead communicates through the clips and the music in it. In this movie there is also a showreel with different projects from students on BTH.

Full textAbstract:
We consider the problem of finding, constructing, and classifying nice polynomials. After a short history of previous results, we present a general property of nice polynomials which leads to an important modification of the concept of equivalence classes of nice polynomials. We give several important results on nice symmetric or antisymmetric polynomials with an odd number of roots, which dramatically increase the speed of a computer search for examples. We present complete solutions to the symmetric three root case, the general three root case, and the symmetric four root case. We also give the relations between the roots and critical points for the general four root case and the symmetric five, six, and seven root cases. Using the relations for the general three and four root cases, we state, without proof, the suggested pattern for the relations for the general N root case. We present several important examples antisymmetric polynomials with five distinct roots and the first known examples of nice polynomials with six distinct roots. To conclude our study, we present several open problems and new conjectures suggested by our results, examples, and computer searches.

Full textAbstract:
Tarkastelen pro gradu -tutkielmassani suomalaisten jääkiekkoseurojen nimiä. Aineistoni sisältää kaikki vuonna 2015 Suomen Jääkiekkoliittoon kuuluvien seurojen nimet. Niitä on yhteensä 360. Tutkin nimien rakennetta, miltä osin se on typologista tutkimusta. Tutkin myös nimenantoperusteita kieliyhteisön jäsenen näkökulmasta ja nimistön muuttumista erityisesti 1990-, 2000-luvulla ja kuluvan vuosikymmenen aikana. Tutkimukseni on siis myös vahvasti sosio-onomastista.
Jääkiekkoseuran nimessä tärkeä elementti on paikantava määriteosa, joka on nykyään noin 70 %:lla nimistä. Kaksiosainen nimi on yhä yleisin, mutta nimet ovat muuttuneet myös pidemmiksi. Perusosa on yli puolella nimistä informatiivinen ja se kertoo yleensä lajin tai sen, että kyseessä on urheiluseura. Perusosan tarkoite voi olla myös muun muassa eläimennimitys, ominaisuudennimitys tai ihmisjoukko.
Samalla nimellä voi olla useita nimenantoperusteita. Selvästi yleisin on informatiivisuus ja toiseksi yleisin metaforisuus. Jääkiekon erikoiskieli on hyvin kuvainnollista urheilukieltä, joten on luonnollista, että se näkyy nimistössäkin. Eläinmetaforanimet ovat säilyneet nimimuodissa jo pitkään. Jääkiekkoseurojen nimissä on myös metonyymisiä siirrännäisiä. Muut nimenantoperusteet ovat harvinaisia, mutta niitä ovat muun muassa symboli, huumori, sanaleikki, alkusointu ja loppusointu.
Olen kiinnittänyt erityistä huomiota jääkiekkoseurojen nimien kieliin. Viime vuosikymmeninä seurannimet ovat muuttuneet sekakielisemmiksi. Nimissä on usein sekä suomea että englantia. Kuluvana vuosikymmenenä on annettu jopa enemmän englannin- ja sekakielisiä nimiä kuin suomenkielisiä. Nimimuodissa näyttää olevan HC eli hockey club -nimielementin sisältävät nimet. Jos uusi seurannimi on muotoa HC + paikkakunta, se vähentää metaforisuutta. Muussa tapauksessa englanninkielen lisääntyminen ei siihen merkittävästi vaikuta.
Jääkiekkoseurojen nimistössä on tällä hetkellä menossa murrosvaihe. Seurat vaihtavat nimiään monesta eri syystä. Vanhat nimenosat halutaan usein säilyttää uudessa nimessä.

Full textAbstract:
This is a collection of short stories that traces a chronological movement through one family's experience of the mother's illness. Each piece in the collection is meant to be an independent, free-standing short story. Each story is different, told from distinctive points-of-view, angles, and voices. However, every story covers a span of time within the nine months of the family's experience, in the presented order, as part of a collective movement toward the core. All together, the pieces hope to reflect a mosaic of sorts--one that tells a story that cannot otherwise be told.

La interacción persona-ordenador (HCI) estudia la relación entre usuarios y sistemas computacionales. Sin embargo, se concentra primordialmente en el control explícito, mediante dispositivos como el teclado o el ratón. A medida que los sistemas se vuelven más complejos, esta aproximación tradicional limita interacciones más naturales e intuitivas.
Sin embargo, HCI puede incorporar información implícita del usuario a través de la Fisiología Computacional, dedicada a medir cambios psicofisiológicos (afectivos, perceptivos o cognitivos) para adaptar sistemas sin control explícito del usuario. Asimismo, el sonido ofrece ventajas para representar dichos estados, ya que puede ser procesado más rápidamente que las presentaciones visuales, es fácilmente localizable, posee una resolución temporal alta, y permite presentar múltiples flujos de datos simultaneamente.
Esta tesis doctoral tiene por objetivo conceptualizar, prototipar y evaluar interacciones sonoras basadas en fisiología computacional implícita, en contextos HCI. En concreto, se evaluan sus cualidades de perceptualización, el rol de la complejidad de los mappings entre información fisiológica y sonido, y sus implicancias en la creación musical.The field of Human-Computer Interaction (HCI) is devoted to understand the interplay between people and computers. However, it is mainly based on explicit control by means of devices such as the keyboard and mouse. As systems become increasingly complex, this traditional approach constitutes a bottleneck for seamless HCI. However, HCI can incorporate implicit user information through Physiological Computing, which monitors psychophysiological states (affective, perceptive or cognitive) for adapting computer systems without explicit user control. At the output level, sound appears as an excellent medium for representing implicit states, as it can be processed faster than visual presentation, can be easily localized, it has a good temporal resolution, and account for multiple data display. In this dissertation we conceptualize, prototype and evaluate sonic interactions for implicit Physiological Computing in the context of HCI, focusing on their perceptualization quality, the role of mapping complexity, and their meaningfulness in the musical domain.

Full textAbstract:
ABSTRACT
The use of the arts as a tool for conflict transformation, or what has been called arts based peacebuilding, is a new and emerging field. Yet, there is sparse empirical evidence on its outcomes. The Nile Project, a musical collaborative from East Africa that brings together musicians from all of the countries that border the Nile River, is aimed at finding a solution to the dire water conflict and crisis in the region. This study aims to explore how their collaborative process of creating and performing music despite their linguistic, cultural, musical, and political differences, can illuminate how music can be used to address conflict. Using a combination of collaborative qualitative and arts-informed research methodologies, original members of the collective as well as the co-founder were interviewed. Observations were also done of the musicians' rehearsals, performances, and classroom visits at a New England University and during a musical residency in Aswan, Egypt. Findings suggest that an outcome of the Nile Project's work is the development of relationships, deeper learning, particularly about other Africans, and that the process of making music with those from diverse musical traditions can act as a way to practice peacebuilding skills: creating unity, while honoring diversity. This study seeks to add to a limited amount of research documenting the arts in peacebuilding suggesting that music might be an effective tool for transforming conflict.

This case describes how Nike, a consumer goods company with an ever expanding portfolio and a tremendous brand value, manages the tradeoff between local responsiveness and global integration. In particular, the case highlights Nike's organizational structure that consists of a global matrix organization that is replicated at a regional level for the European market. While this organizational structure allows Nike to respond to local consumer tastes it also ensures that the company benefits from integration advantages such as global marketing and sourcing. Supported by rich quotes from Nike managers on various organizational levels, this case draws a colorful picture of all the challenges involved that come with matrix and regional structures. Will Nike be able to better exploit its competitive advantage by introducing more regional structures in the future? What is the logic behind the Nike's regional structure?Series: WU Case Series

MUSIC FOR NINE INSTRUMENTS is a single movement composition for flute, oboe, Bb clarinet, bassoon, horn in F, two violins, viola, and 'cello. The work is organized into six sections, each of which examines and utilizes the compositional material in unique ways. The syntax of the work is achieved by the employment of pitch-class sets. Two sets of pitches are used with their sub-sets. The properties indigenous to the two sets are that they are of seven and five-members respectively, the five-member set is not a subset of the seven-member set and, when the two sets are catenated, they form the universal-set of the twelve pitches of the chromatic scale. Additionally, the work exploits the individual characteristics of the instruments and explores, in various ways, the textural combinations available.School of Music

Mestrado em FinançasEste projeto contém uma avaliação detalhada e respetiva estimativa do valor das açõoes da Nike, Inc para o final do ano fiscal de 2020, tendo em conta o projeto final do Mestrado em Finanças do ISEG. A escolha da empresa Nike, Inc deriva do meu gosto pessoal por ténis e roupa de desporto, especialmente da marca Nike, que eu tenho vindo a usar desde os meus tempos de criança. O preço-alvo foi obtido através de um modelo absoluto de avaliação, mais concretamente, o método do Flow to Equity (FTE). Adicionalmente, usámos o método de avaliação relativa, de maneira a complementar a decisão do método anterior e usámos ainda o método de Desconto de Dividendos, com o intuito de obter um preço-alvo baseado no desconto de dividendos futuros, uma vez que a empresa tem uma politica de dividendos atraente para os investidores, mas com a limitação de uma conservadora taxa de pagamento de dividendos, resultou numa recomendação de venda e um preço-alvo irrealista. Foi realizada uma análise de sensibilidades de maneira a complementar e dar apoio à decisão de investimento. Com um preço alvo de $88.66 no FA fiscal de 2020, um potential de valorização de 15.23% em relação ao preço em 31 de Maio de 2019, a nossa recomendação final é de compra das ações da Nike, tendo em consideração os riscos que poderão ocorrer e afetar o desempenho da empresa.
This project contains the detailed valuation and the respective estimation of Nike, Inc intrinsic shares value for the fiscal 2020YE, according to ISEG´s Master in Finance final work project. The choice of Nike, Inc comes from my personal interest in footwear and sports apparel, and mainly from Nike products, which I´ve been using and wearing since my childhood days. The price target was obtained through an absolute valuation model, more specifically, the Discounted Cash Flow (DCF) model. In addition, we used the Relative Valuation approach as a complement method to support the final recommendations, and the Dividend Discount Model (DDM), with the purpose of obtaining the price target based on the discount of future dividends, since the company has an attractive dividend policy for investors, but with the limitation of a conservative payout ratio, resulted in a sell recommendation and unrealistic price target. A sensibility analysis was performed in order to complement and support the investing recommendation. With a price target of $88.66 at fiscal 2020 YE, an upside potential of 15.23% relative to the price on May 31st 2019, our final recommendation for Nike, Inc shares is to BUY, taking into consideration the risks that may occur and affect the company´s performance.

Nimes doit sa naissance a la presence d'une importante source perenne jaillissant autrefois dans un environnement remarquable. Cette exsurgence fut l'objet d'un culte de fertilite/fecondite consacre au dieu topique nemausus, aux ancetres et aux meres. Dans le sanctuaire que l'on a etabli a cet endroit, la gestion de l'eau a joue, grace a un systeme complexe de canalisations, un role essentiel en permettant la mise en uvre d'une scenographie autour d'un lacus architecture ainsi que l'etablissement d'une premiere adduction. Par ailleurs, si l'on n'a pas retrouve de citernes, on a recense un grand nombre de puits dont l'usage, introduit lors de la conquete, s'est poursuivi sans interruption du fait de la presence d'une nappe phreatique peu profonde. Vers le milieu du 1er s. Ap. J. -c. , un accroissement des ressources a ete assure par un aqueduc venant d'uzes tandis qu'il en aurait existe un plus enigmatique, se dirigeant vers la campagne. L'eau des adductions etait distribuee par un reseau compose de tuyaux de plomb normes dont on a retrouve d'exceptionnelles traces et circulant soit dans des gaines soit dans des galeries techniques ou encore dans les grands egouts. Des thermes dont l'apparition pourrait etre contemporaine de l'augusteum, des fontaines et des bassins notamment, fonctionnaient grace a ce reseau. Afin d'assainir, aussi bien les habitats de hauteur que de plaine, tout en tenant compte du passage intra muros de deux cours d'eau, les hydrauliciens romains ont du repartir judicieusement les eaux usees et de ruissellement pour eviter l'engorgement des canalisations. Il l'ont fait notamment grace a la constitution de "bassins d'egouts" et en augmentant le gabarit des grands collecteurs. Les memes preceptes ont ete adoptes avec succes pour la realisation du reseau de l'amphitheatre flavien. Les ecoulements des grands egouts, du cadereau et du ruisseau de la fontaine rejoignaient enfin le vistre en franchissant le rempart aux points les plus bas de la ville.

Este trabalho trata sobre o desenvolvimento de sensores magnéticos tipo fluxgate baseados em tecnologia planar. O material utilizado como núcleo é baseado em trabalhos anteriores que determinaram os melhores parâmetros de eletrodeposição de ligas de NiFe para esta aplicação. Foram criados dispositivos funcionais mostrando a usabilidade do material. Também foram propostos 4 novos leiautes com o propósito de melhorar características como sensibilidade, preço, consumo de potência e resolução se comparados com sensores similares atuais. Inicialmente somente dispositivos em escala de milímetros foram criados utilizando placas de circuito impresso como substrato e um processo litográfico baseado em toner de impressora a laser. Este processo é muito simples e permite uma rápida ida do desenho ao protótipo em escala macro sem necessitar de equipamentos especiais. Note que ao contrário de macrofluxgates convencionais, estes dispositivos pode ser diretamente escalonados. Estes protótipos fornecerão os dados necessários para a construção de micro sensores otimizados. Para calcular a intensidade do campo magnético ao qual o núcleo está submetido foram feitas simulações de elementos finitos. A pequenas distâncias do plano, menores que a separação entre as espiras e onde o núcleo ferromagnético se situa, o campo é muito influenciado pela periodicidade da bobina, dando origem a um campo com oscilações periódicas de grande amplitude. Os efeitos desta alta inomogeneidade não é bem conhecido. Utilizando as curvas de histerese medida para os filmes de NiFe foram obtidas as curvas de resposta simulada para um fluxgate. A sensibilidade e a região linear em função do campo de excitação também foram simuladas. Enquanto que a sensibilidade tem um máximo para campos pouco mais intensos que o de saturação do material, decrescendo posteriormente, a região linear apresenta um pico para campos excitatórios baixos. O primeiro foi confirmado pelos resultados experimentais que também mostraram evidências do segundo. Os quatro leiautes são basicamente dois tipos com uma versão dupla cada um. Isto é, empilhando duas camadas de bobinas idênticas consegue-se multiplicar por raiz de dois o campo de excitação utilizando a mesma potência e dobrar o número de bobinas coletoras. Os leiautes propostos mostraram melhor sensibilidade, até oito vezes maior, se comparados com uma referência tirada da literatura. Também o ruído foi menor nas versões de dupla camada. O melhor apresentou um ruído menor que 1/3 da referência, ambos com potências de 1 Wrms. Mas todos leiautes propostos tiveram menor região linear. Todas estas características também foram estudadas em função da potência aplicada que está diretamente ligada a amplitude do campo de excitação.This work present the development of fluxgate magnetic field sensors based on planar technology. The material for the core of the device is based on early works that determined the best NiFe electrodeposition parameters for this application. Functional devices were created proving the usability of the alloy. Also 4 new layouts were proposed in order to build more sensitivity, cheaper, less power consumption and better resolution sensors. Firstly, only macro scale devices were created using printed circuit board as substrate and a laser printer toner based lithography. This process is very simple and allows a fast way from sketch to macro scale prototypes with no need of special equipments. Unlike the conventional macrofluxgates, these devices can be directly scalonable. This prototypes characterization data will be used to produce optimized microsensors. Some finite element simulations computed the magnetic field produced by a square planar coil to predict the intensity that the core is immersed on. At small distances from the coil\'s plane, smaller than the separation between wires, where the core stands, the field is very influenced by the periodicity of the coil giving rise to periodic profiles. The effects of this high inhomogeneity is not well known. Using the measured hysteresis curve from the NiFe films, the simulated response of a fluxgate sensor was obtained. The simulated sensitivity and linear range as a function of the excitation field amplitude showed some unexpected results. While the sensitivity has a maximum with excitation fields just above the core saturation values decreasing later on, the linear range shows a high peak in low field region. The first were confirmed by the experimental data that also showed strong evidences of the existence of the second one. The 4 new layouts are basically 2 with a double version each. That is, stacking two identical coil layers in order to multiply by 1.41 the excitation field using the same power, double the number of pick-up coils and minimize the undesired perpendicular magnetic field produce by planar coils. The new layout prototypes had better sensitivity, up to eight times higher, related to the reference one taken from literature. Also the noise measured was smaller in the double layers version. The best one presented more then three times less noise than the reference for a power of Wrms. But all of them presented smaller linear range. All this sensors characteristics where also studied as a function of the applied power, that is directly related to the excitation field.

This thesis will be an exploration of the issues of building in the Egyptian landscape. Human inhabitation of the Egyptian landscape has for many thousands of years been centred within the zone of the Nile River valley. In the past, this ribbon of arable land was able to support the food requirements of the population and produce a surplus of agricultural products for export. Today, Egypt's population of 54 million exists on 30,000 km.2 of habitable area concentrated in the Nile River valley out of a total area of approximately one million sq. km. The population is growing rapidly, and in fact, in areas of urban growth, illegal building is occurring on scarce arable land. In the 1970's, in an effort to divert such growth, strategies for newtowns situated in the interior of the desert were planned, and several were executed. However, I propose to put forward an attitude of growth that would run North-South, to build on the desert edge, above and parallel to the Nile valley where existing arable land meets desert and to extend arable zones into the desert. In the course of this project, I will examine a) -as preface -the Nile valley in context to the historic development of an irrigation society: trace the domestication of the Nile. b) -as observation of the desert - formal and spatial inhabitations in the regional landscape and from other similar landscapes c) - as projection of the possible-an agricultural research centre which by its raison d'etre will maintain a distinction of what landscape is built and what remains free for new cultivation. The building will include work spaces, labs, sleeping and living facilities for both permanent and short term staff.

This collection of short stories explores the different ways women tolerate violence in exchange for some form of validation. The narratives focus on women and the reverberations of small moments which carry violent mass. While the violence occasionally includes physical elements, the collection is more concerned with the ways women accept emotional and psychological violence—specifically from men. Themes, motifs and symbols from the Clytie-Helios myth are threaded throughout the collection as well as a concern for space and touch, art and the creation of art, silence and voice. All of these elements involve control as the women characters in these stories struggle to resist their own objectification. A critical introduction which explains how form and language amplify story precedes the collection.

Nice is a multinational company based in Oderzo (TV) founded in 1993 and in only twenty-eight years of its life has achieved important results in the home automation market. The reason why I have chosen to study this firm is mainly for three different reasons: firstly, I live in Oderzo and Nice is the most known firm in the area in terms of size and reputation; secondly, I am very fascinated by capital markets dynamics and Nice is a perfect example since it was listed in the MTA-STAR segment managed by Borsa Italiana S.p.A in 2006 and afterwards, the company was delisted in 2019. Thirdly, I have a huge interest for this company and a great respect for the founder and chairman Mr. Lauro Buoro and for employees, due to the fact I have also attended my first curricular internship lasted one month in that company for my Bachelor's degree from July to August 2017.

Au Wurm, un important mouvement régressif de la mer lié aux mécanismes glacio-eustatiques en Méditerranée provoque l’exondation des bassins côtiers et génère un surcreusement des basses vallées. A l’Holocène, un mouvement transgressif eustatique est à l’origine du comblement des paléoreliefs sis au droit de l’agglomération niçoise. L’analyse de nombreux sondages permet de proposer un essai de reconstitution de la topographie des paléoreliefs wurmiens et de définir la géométrie et la lithostratigraphie de la séquence de remplissage. Le secteur d’étude est organisée deux bassins de sédimentation avec à l’Ouest le bassin de Nice-centre et à l’Est le bassin de Nice-Riquier. Ces formations de remplissage, décomposables en plusieurs aquifères à nappes libres, semi-captives et captives, drainent les formations hydrogéologiques perméables entaillées par les vallées wurmiennes. Grâce à de nombreuses données piézométriques, nous proposons une carte enisopièzes de la nappe libre et une étude des variations du niveau statique. Les eaux de cette nappe peuvent être agressives envers les bétons (eaux séléniteuses, biseau salé). Des ouvrages souterrains ont modifié les conditions d’écoulement de la nappeIn Wurm, a large regressive overlap of the sea, connected with glacio-eustatic mechanisms in the Mediterranean, induce an exundation of castal basins and generate a deepening of low-valleys. In Holocene, an eustatic transgressive overlap is at the beginning of filling of wurmian’s paleoreliefs. The analysis of the several drillings allows to propose a reconstruction of the wurmian’s paleorelief topography, and to specify the lithostratigraphy of the filling sequence. The sector of the study is organized in two sedimentary basins : on the West side, the basin of Nice-centre ; on the East side the basin of Nice-Riquier. These filling formations which can be split into several water-bearings with free, semi-captive and captive sheets. Those water-bearing drain the permeable hydrogeologic formations notched by Wurmian’s valleys. Thanks to several piezometric datas, we propose a map for the free sheet and a study of the variations in the static level. The water contained in this sheet could be aggressive toward concretes.

Full textAbstract:
Fundação de Amparo a Pesquisa no Estado do Rio Grande do SulThe Exchange Bias (EB) phenomenon consists of an interfacial exchange coupling between a ferromagnetic (FM) material and an antiferromagnetic (AFM) one and has as the main characteristics the rise of a unidirectional anisotropy and a rotational hysteresis (HR) in torque curves. In this work we have investigated the behavior of the magnetic behavior of systems presenting EB through magnetization curves, anisotropic magnetorresistance (AMR)and torque magnetometry. We have grown films, via magnetron sputtering, of NiFe/FeMn (bilayers) with different thickness of the FM layer and film structures of NiFe/IrMn/Ta with different repetitions of the basic s tructure. From the X-ray diffraction and reflectivity we have determined the preferential crystallographic growth direction, the thickness and the grain size of the studied samples. It was implemented at the Magnetism and Magnetic Materials Laboratory (LMMM) an apparatus to measure the AMR in two configurations: resistance as a function of the applied field angle and resistance as function of the field applied in a particular angle direction. To adjust the magnetization and AMR data we have used a phenomenological model for EB considering four energy terms: Zeeman, uniaxial, unidirectional and magnetostatic. The AMR curves have shown an asymmetry around 180º when measured at field smaller than the Bias one. According to the used model used, such asymmetry can be caused either by a misalignment between the anisotropy axes (uniaxial and unidirectional) or by a misalignment between the measurement current direction easy magnetization axis of the sample. It was not observed in the multilayers an increase on the uniaxial anisotropy dispersion with increasing on the trilayers number, as expected. In order to fit average torque curves, we have used an equation with two harmonic terms. The resulting parameters allow us to study the field evolution of the harmonic amplitudes Kθ e K2θ. In the multilayer system as higher total energy is, higher is the energy losses by HR. In bilayers system, the HR energy losses still increases even above the saturation field. Such behavior was associated to the configuration of interfacial spins and suggests the need of an additional contribution to total energy of the magnetic system.
O fenômeno de Exchange Bias (EB) consiste de um acoplamento de troca interfacial entre um material ferromagnético (FM) e um material antiferromagnético (AFM) e tem como características principais o surgimento de uma anisotropia unidirecional e a histerese rotacional (HR) em curvas de torque. Neste trabalho investigamos o comportamento de sistemas magnéticos com EB através de curvas de magnetização, magnetorresistência anisotrópica (AMR) e magnetometria de torque. Foram crescidos filmes via magnetron sputtering, de NiFe/FeMn (bicamadas) variando a espessura da camada de NiFe e filmes de NiFe/IrMn/Ta com diferentes números de repetições dessa estrutura básica (multicamadas). A partir da difração e refletividade de raios-X determinamos a direção preferencial de crescimento cristalográfico, espessura e o tamanho de grão das amostras estudadas. Foi implementado no Laboratório de Magnetismo e Materiais Magnéticos (LMMM) um aparato experimental para medidas de AMR: resistência em função do ângulo do campo aplicado e resistência em função do campo aplicado para um determinado ângulo escolhido. Para o ajuste aos dados das curvas de magnetização e AMR é apresentado um modelo fenomenológico para EB considerando quatro termos de energia: Zeeman, uniaxial, unidirecional e magnetostático. As curvas de AMR apresentam uma assimetria em torno de 180º quando medidas em valores de campo menores que o campo de Bias. De acordo com o modelo utilizado, tal assimetria pode ser causada por um desalinhamento entre os eixos de anisotropia (uniaxial e unidirecional) ou por um desalinhamento entre a direção da corrente de medida e o eixo fácil de magnetização da amostra. Não foi observado um aumento na dispersão da anisotropia uniaxial com o aumento das repetições das tricamadas, conforme esperado. Para o ajuste das curvas de torque médio utilizamos uma equação com dois termos harmônicos. Os parâmetros resultantes do ajuste das curvas de torque permitiram estudar a evolução das componentes harmônicas Kθ e K2θ. Nas multicamadas quanto maior a energia associada ao torque médio maiores são as perdas de energia por HR. Já nas bicamadas, as perdas de energia por HR aumentam mesmo acima do campo de saturação. Tal comportamento foi associado à configuração de spins interfaciais e sugere a necessidade de uma contribuição adicional para a energia total do sistema magnético.

This work reports the study of the phenomenon of exchange bias in NiFe/IrMn bilayers and NiFe/IrMn/Co trilayers. In the NiFe/IrMn bilayers, ferromagnetic resonance experiments at X and Q bands microwave frequencies reveal that spin wave and NiFe resonance modes are excited by the oscillating microwave field. Angular variations of the absorption fields in the plane of the films for both resonance modes shows the effect of the unidirectional anisotropy field, whose intensity is twice larger for the spin wave mode, due to an additional contribution of an unidirectional surface anisotropy. The experiments also indicate the presence of a uniaxial anisotropy of the NiFe layer, apparently dependent on the applied magnetic field. The magnetic parameters of both resonance modes were deduced considering a generalized phenomenological model which also includes the contribution of a rotatable anisotropy. In the NiFe/IrMn/Co trilayers, the angular variations of the resonance field in the plane of the films reveal the effect of the unidirectional anisotropy field for both independent resonance modes of NiFe and Co layers. The ferromagnetic resonance results combined with magnetometry data show that the exchange bias phenomenon at the NiFe/IrMn interface influences the same phenomenon at the IrMn/Co interface, and that this effect must be mediated by a spiral structure of spins across the IrMn antiferromagnetic layer. For both systems studied, the values of the exchange bias field deduced from the ferromagnetic resonance experiments are consistent with the values given by magnetization measurements.
Este trabalho relata o estudo do fenômeno de exchange bias em bicamadas NiFe/IrMn e tricamadas NiFe/IrMn/Co. Nas bicamadas NiFe/IrMn, experimentos de ressonância ferromagnética, em Bandas X e Q de frequência de micro-ondas, revelam que um modo de ressonância de ondas de spin e o modo de ressonância da camada de NiFe são excitados pelo campo oscilante de micro-ondas. Variações angulares dos campos de absorção no plano dos filmes mostram para os dois modos de ressonância o efeito do campo de anisotropia unidirecional, cuja intensidade é duas vezes maior para o modo de onda de spin, devido a uma contribuição adicional de uma anisotropia de superfície unidirecional. Os experimentos indicam também a presença de uma anisotropia uniaxial da camada de NiFe, aparentemente dependente do campo magnético aplicado. Os parâmetros magnéticos dos dois modos de ressonância foram deduzidos considerando um modelo fenomenológico generalizado que inclui também a contribuição de uma anisotropia rodável. Nas tricamadas NiFe/IrMn/Co, as variações angulares de campo de ressonância no plano dos filmes revelam o efeito do campo de anisotropia unidirecional sobre os modos de ressonância independentes das camadas de NiFe e Co. Os resultados de ressonância ferromagnética combinados com os dados de magnetometria, mostram que o fenômeno de exhange bias na interface NiFe/IrMn influencia o mesmo fenômeno na interface IrMn/Co, e que esta influência deve ser mediada por uma estrutura espiral de spins através da camada antiferromagnética de IrMn. Para os dois sistemas estudados, os valores do campo de exchange bias dados pelos experimentos de ressonância ferromagnética estão de acordo com os valores fornecidos por medidas de magnetização.

The aim with this study was to answer the question “What components in Nike’s viral ads on Youtube trigger emotions?”. The data was collected through a qualitative and descriptive research approach and the method was a combination of a poetic film analysis and Ducoffe’s Model of Advertising Value. The model includes three components that were to be analyzed: informativeness, entertainment and irritation. The video ads were analyzed together with the comments posted. The comments were seen as electronic word of mouth and they were analyzed in order to understand if the viewer felt positive or negative emotions towards the ads. The findings showed that Ducoffe’s Model of Advertising Value was applicable on social media networks such as Youtube. Informativeness and entertainment were the most important components triggering emotions. Since marketing events nowadays are digitalized, it is important to adapt previous models and research to new platforms.

Full textAbstract:
The topos of the Nine Worthies and Nine Worthy Women was widely used in a variety of media across western Europe throughout the late medieval and early modern period_ While many scholars have commented on the Worthies, few have questioned their meaning. The common assumption is that these figures simply represented chivalric virtue and that this meaning remained relatively unchanged through their long history_ This thesis challenges that assumption by examining the contexts in which this imagery was used. Through a series of case studies ranging across geographic areas, media and periods, it demonstrates that the Worthies' meaning was complex, shifting and flexible - and that it was precisely this flexibility that made them so useful. Previous studies have tended to assume literary origins and paths of transmission of the topos. This thesis argues that this imagery was performative. It examines how the Worthies were used to negotiate between different layers of authority, and how they crossed social, temporal and spatial boundaries. The 'canon' of Worthy Women was more variable and less frequently used than the male version. The thesis compares the differing origins, use and reception of male and female Worthies and examines possible reasons for this disparity.

Válvulas de Spin têm sido utilizadas na fabricação de sensores magnéticos e memórias de acesso randômico, sendo muito importantes do ponto de vista tecnológico. Neste trabalho, foram exploradas as análises das curvas de reversão de primeira ordem da magnetorresistência (MR-FORC), bem como ajustes das curvas de histereses da magnetização e magnetorresistência, para estudar o fenômeno de exchange-bias, anisotropia magnética e propriedades magnetorresistivas. As válvulas de spin estudadas foram do tipo NiFe/Cu/NiFe/IrMn, tendo camadas semente e de cobertura de Ta, preparadas por sputtering. Um modelo fenomenológico de parede de domínios no material antiferromagnético (AFM) foi utilizado, levando em conta as anisotropias magnéticas e interações entre as camadas. Também foram consideradas certas dispersões da anisotropia dos grãos ferromagnéticos (FM) e antiferromagnéticos (com distribuições Gaussianas) em torno dos respectivos eixos de anisotropia uniaxiais. Para o ajuste da magnetização para algumas amostras, foi necessário utilizar uma rotação no plano de um ângulo nos eixos de anisotropia uniaxiais do FM e AFM, em relação à direção do campo magnético aplicado durante a deposição dos filmes. Bons ajustes das curvas de histereses das magnetizações foram obtidos nas direções medidas do campo magnético aplicado. Um método baseado em medidas de variações angulares da magnetorresistência em campos constantes foi proposto para extrair este ângulo para cada amostra. Foram obtidas razoáveis concordâncias entre estes ângulos e os correspondentes extraídos dos ajustes das curvas de magnetização. Através da análise dos diagramas da MR-FORC e de simulações indicados dos resultados dos ajustes das histereses da magnetização, foi encontrada uma relação direta entre os campos de interação (e suas incertezas) com os campos de exchange-bias (HEB) dos grãos da distribuição (extraídos das simulações, usando a largura da distribuição obtida do ajuste). Resumindo, esta análise mostrou que esta técnica permite extrair informações comparativas sobre a dispersão dos eixos de anisotropia dos grãos FM e AFM em torno do eixo de anisotropia uniaxial, o que pode ser importante na caracterização dos sensores magnetorresistivos. Além disso, análise dos diagramas MR-FORC indicaram início da presença de descontinuidade na camada de NiFe presa em 27, com um aumento acentuado (acima do previsto) para a amostra com 25. Este aumento acima do previsto corrobora com nossa hipótese. As simulações das curvas de histerese da magnetorresistência não foram muito bons, indicando que melhorias devem ser introduzidas no modelo utilizado para a simulação da histerese da magnetorresistência, obtidos a partir dos ângulos das camadas ferromagnéticas livre e presa. A questão referente a presença em algumas das amostras de um desalinhamento entre os eixos fácéis do FM e do AFM ainda é uma questão em aberta, mas neste trabalho foi encontrado que este ângulo é igual a 2.Spin Valves have been employed as magnetic sensors and used in random access memories, showing they are very important in terms of technological point of view. In this work, analyses of the magnetoresistance first order reversal curves (MR-FORC) have been used, as well as fittings of the magnetization and magnetoresistance hysteresis, to study the exchange-bias phenomena, magnetic anisotropies and magnetoresistance in spin valves. Sputtering has been used to the deposition of NiFe/Cu/NiFe/IrMn, and Ta has been deposited as seed and buffer layers. A domain wall model (in the antiferromagnetic layer) taking into account the magnetic anisotropies and the interactions between the layers has been employed to fit the magnetization hysteresis. Some textures have been also introduced to take into account the ferromagnetic (FM) and antiferromagnetic (AFM) grains dispersion (with Gaussian distributions) centered around the respective uniaxial anisotropy axes. However, to obtain good fits for some samples, it has been necessary to include an in-plane rotation of an angle of the both FM and AFM easy axes in relation to the field direction applied during the growing of the films. Good fits of the magnetization hysteresis have been obtained for all measured directions of the applied field. A new method based on the angular variation of the magnetoresistance to constant fields has been proposed to extract directly these angles. Reasonable agreements have been obtained between these angles and the corresponding ones extracted from the fits of the magnetization loops. Through the analyses of the MR-FORC and from the simulations indicated by the parameters (obtained from the fittings of magnetization loops), a direct relation between the interaction fields (and its uncertainties) and the exchange-bias fields of the grains of the distribution (extracted from the simulations, using the width of the distribution obtained from the magnetization fittings) has been identified. In summary, this analysis has showed that this technique allows to extract comparative information about the dispersion of the anisotropy axes of the FM and AFM grains around the uniaxial axis, which can be very import to the characterization of spin-valve based sensors. Besides, MR-FORC analyses have also indicated the presence of a threshold of discontinuity of the pinned NiFe layer at 27, showing a huge increase (above of the expected) to the sample at 25, and this unexpected increasing has corroborated with our hypothese. Simulations of the magnetoresistance loops have not been good, indicating that improvements should be included in the model employed to simulate these curves, obtained from the pinned and free angles of the NiFe layers. Concerning the case of the presence of misalignments of FM and AFM for some samples, it is still an open question, but in this work, we have found that this angle () is equal to 2.

Devido ao aumento na produção de óleo pesado, a indústria do refino voltou-se para os processos de hidrocraqueamento (HCC) que fornecem combustíveis básicos e leves atendendo as exigências da sociedade moderna. O processo HCC é realizado, geralmente, sob temperaturas e pressões elevadas na presença do hidrogênio e de um catalisador de hidrocraqueamento. As cargas de petróleo brasileiras inevitavelmente contêm muitas impurezas, como os compostos orgânicos nitrogenados. Estes compostos de nitrogênio presentes nas cargas de hidrocraqueamento atuam como venenos temporários dos catalisadores, resultando numa diminuição de atividade destes catalisadores. Normalmente, os catalisadores de HCC compreendem de um suporte ácido mais um componente hidrogenante selecionado do Grupo VIB e do grupo VIII da Tabela periódica dos Elementos, na forma de óxido ou sulfeto. Zeólita Beta e SAPO-5 foram propostos para serem usados como suportes ácidos. A respeito do componente hidrogenante, a combinação de metais usados, expressada como óxidos, foi NiO-MoO3. Uma série de catalisadores NiMo suportados em Zeólita Beta e SAPO-5, de diferentes composições, foram preparados por impregnação seqüencial úmida dos materiais utilizando soluções aquosas precursoras de Ni(NO3)2.6H2O e (NH4)6 Mo7O24. 4H2O. Os suportes e catalisadores foram analisados pelas técnicas: Difração de raios-X (DRX), Espectrometria de Emissão Atômica de Plasma Acoplado Induzido (ICPAES), Adsorção Física de N2 pelo método BET, Redução com Temperatura Programada (RTP), Microscopia Eletrônica de Transmissão (MET), Espectroscopia no Infravermelho de piridina adsorvida (IV), Espectroscopia de Refletância Difusa (DRS) e Espectroscopia de Ressonância Magnética Nuclear (RMN). Os catalisadores NiMo sulfetados foram avaliados usando um reator tubular de fluxo contínuo, no hidrocraqueamento do cumeno na presença e ausência de piridina. Foi verificado que os catalisadores suportados em zeólita Beta promoveram maiores conversões que os suportados em SAPO-5, principalmente o que usou zeólita Beta (Si/Al=8,2) com 4%NiO e 15%MoO3. A presença da piridina foi prejudicial à performance de todos os catalisadores, inclusive para os padrões cedidos pelo CENPES.
Due to the increasing of the heavier crude oil feedstocks production, the oil refining industry has turned to hydrocracking (HCK) processes to provide the lighter basic fuels which modern society demands. The HCK process is generally carried out under high temperatures and pressures in the presence of the hydrogen and a HCK catalyst. The feedstocks of the Brazilian crudes inevitably contain many impurities, such as organic nitrogen compounds. These nitrogen compounds present in the feeds of hydrocracking process act as, temporary poisons to the catalysts, thereby decreasing the catalyst activity. Usually, hydrocracking catalysts comprise of an acidic support plus a hydrogenating component selected from the Group VIB metals and Group VIII metals of the Periodic Table of the Elements, in their oxide or sulfide form. Beta zeolite and SAPO-5 are proposed as acidic support materials for hydrocracking. Regarding the hydrogenation component the combination of the metals used in the form of oxides, was NiO-MoO3. A series of NiMo catalysts supported on Beta zeolite and SAPO-5, of different compositions, were prepared by sequential incipient wetness impregnation of the materials with aqueous solutions of Ni(NO3)2 . 6H2O and (NH4)6 Mo7O24.4H2O. The supports and catalysts were analyzed by several techniques such as: X-ray diffraction (XRD), plasma-emission spectrometry (ICP-AES), N2 physical adsorption by BET method, temperature programmed reduction (TPR), transmission electronic microscopy (TEM), infrared spectroscopy of adsorbed pyridine (IR), diffuse reflectance spectroscopy (DRS) and nuclear magnetic resonance (NMR) spectroscopy. The sulfide NiMo catalysts were evaluated using a continuous-flow tubular reactor by the cumene hydrocracking in the presence and absence of pyridine. It was verified that the NiMo catalysts based on Beta zeolite produced the highest cumene conversion than those based on SAPO-5, particularly the one with Beta zeolite (Si/Al=8,2) containing 4%NiO and 15%MoO3. The presence of nitrogen as pyridine was detrimental for the performance of all catalysts, including the standards one, supplied for the CENPES.

Full textAbstract:
This thesis presents the first detailed multiproxy provenance study of the modern Nile catchment, together with Oligocene-Recent sediments of the offshore Nile cone, and demonstrates for the first time that the palaeodrainage of the Nile has remained relatively stable over the last 30 Ma. Detrital mineral and bulk-rock analyses of modern river, wadi and bedrock samples demonstrate the role of basement lithology, sedimentary recycling, and modern geomorphological features in controlling the composition of sediment reaching the Nile cone. The bulk provenance signature of the modern Nile is dominated by the input of basic detritus from the Cenozoic Ethiopian Large Igneous Province. Detrital zircon signatures are dominated by variations in bedrock lithology, and the availability of easily-eroded Phanerozoic cover sediments. These represent an important source of detritus to the river and are characterised by the presence of strongly negative εHf populations at c. 600 and 1000 Ma, and significant populations of pre-Neoproterozoic grains. Young zircon grains derived from Ethiopian Cenozoic volcanic rocks are also recognised in samples from the Blue Nile, Atbara and Nile trunk. The Sr, Nd and Hf signature of Oligocene Nile cone sediments can only be explained if there is significant input of mafic material being received from the hinterland. The Ethiopian Large Igneous Province represents the only possible source for this detritus, indicating that the Nile has been connected to the Ethiopian Highlands since this time. Zircons with U-Pb ages and hafnium isotope signatures compatible with the Ethiopian LIP have been supplied to the Nile cone since at least the Miocene (16 Ma). Such zircons were not observed in Oligocene 2 delta sediments, but Sr, Nd and Hf isotope data for Oligocene delta muds as old as 31 Ma require significant mafic input. The combined U-Pb and Hf-isotope zircon dataset for Nile catchment and cone sediments represents a significant archive that documents the evolution of the North African crust, in particular highlighting phases in the development of the Arabian Nubian Shield and amalgamation of Gondwana in late Neoproterozoic times.

Full textAbstract:
Nine Questions for the Dalai Lama is a DVD Rom that incorporates digital video documentary, video poetry, and written essays that call into question the theoretical framing that informed the practices and decisions that underscored The Dalai Lama Centre for Peace and Education's "Nurturing Compassion Vancouver Dialogues 2006." Although this event was conceived as a youth centred dialogue with the Dalai Lama, it was characterized by the educative practices of 'manageralism' (Fielding 2004) and revealed a 'risk consciousness' (Ericson & Haggerty 1997) at play in the managing of these dialogues. While appearing to collaborate with youth, these practices created a dominant cultural narrative that culminated in the censoring of a youth based documentary produced specifically for this event.
The questions that appear as menu choices emerged from the author's involvement as the
mentor/producer of the youth documentary team. What is real food and real water? Questions meanings of compassion. What were they doing? uses the theoretical underpinnings of the politics of communication to examine the event. What are we afraid of? is an essay that examines the troubling issue of the censorship of a video documentary that identifies the Dalai Lama as the spiritual and political leader of Tibet. This essay views this event through a lens informed from the writings of Arendt (1979) and Brueggeman (2001).
Other menu choices on the dvd question through the medium of digital video the exploration of imaginative spaces as ways of knowing. Who are you and what happens next? Uses a video archive to look at the exclusion of the youth and includes the censored video. How to hold a hand? and Are you trying to tell me something? represent some of the other ways this experience of the event was realized and understood. Why listen to a dream? questions the ways we know through imaginative realization and awareness. This essay questions how the use of the imagination and awareness relates to the dominant narrative that characterized this event and to transformative educational practices.Education, Faculty of

Full textAbstract:
Kashchei is an original music composition scored for nine musicians and electronics with a duration of nineteen minutes. The analytical paper, presented in Volume 1 of this thesis, gives a general overview of the procedures and techniques used to create this piece. Volume 2 comprises the musical score. The electronics are available on the accompanying DVD. The inspiration for the work comes from the characters, visual representations, and sounds of Russian folklore – skazki. This work metaphorically represents the different layers of Kashchei, a prevalent villain in Russian fairytales who can only be defeated by breaking through several layers to reach his soul. The organization of the seven movement work narrates the layers around Kashchei's soul and is woven around a theme quoted from Rimsky-Korsakov's opera Kashchei the Deathless. The sonic environment created by both orchestration and electronics attempts to recreate the surrealism of fairytales and the sweeping gestures and vibrancy of Russian lacquer art.Kachtcheï est une œuvre musicale pour neuf instruments et dispositif électronique, d'une durée de dix-neuf minutes. Une analyse technique de la composition, présentée dans le 1er Volume de cette thèse, fournit une vue d'ensemble des procédures et techniques utilisées dans la pièce. Le 2e Volume contient la partition musicale et la description de la composante électronique. L'œuvre a été inspirée par les personnages, les motifs visuels, et le caractère sonore de la folklore russe – skazki. Cette composition représente de façon symbolique les divers couches de Kachtcheï, un personnage désagréable qui réapparait fréquemment dans les contes de fées russe. Traditionnellement, le héros qui cherche à vaincre Kachtcheï doit franchir plusieurs couches avant d'y arriver à son âme sans doute vulnérable. Structurellement, chacun des sept mouvements de l'œuvre représente une des couches qui protègent cet âme et est basé sur un thème tiré de l'opéra Kachtcheï l'immortel de Rimsky-Korsakov. L'environnement sonore de l'orchestration et du dispositif électronique, ensemble, tente de recréer le surréalisme des contes de fées et les grands gestes et le dynamisme de l'art du laque russe.

Full textAbstract:
A multitude of microorganisms possess the ability to metabolise molecular hydrogen (H2). The major enzyme family involved in hydrogen metabolism are Hydrogenases. These enzymes catalyse the reversible conversion of molecular hydrogen to protons and electrons (H2 ↔ 2H+ + 2e-). These enzymes have the potential to be utilised for biotechnological applications such as hydrogen fuel cells, but they also represent promising drug targets for inhibition of bacterial energy metabolism both within the gastrointestinal tract and after infection. Therefore, further understanding and discoveries made in the hydrogenase field warrants progression into applied medical and biotechnological research areas. Hydrogenases are also interesting due to their phylogeny and physiology in a large number of microbial species. These enzymes are categorised by their active site architecture. One well studied, ancient group is termed the [NiFe]-hydrogenases, which all harbour a complex NiFe(CN-)2CO active site in the 'large' catalytic subunit and usually have three iron-sulfur clusters within a 'small' electron transferring partner subunit. [NiFe]-hydrogenases have undergone massive diversification, with four major phylogenetic subgroups arising. The major part of this Thesis concerns work on a Group 4 [NiFe]-hydrogenase that functions in partnership with a formate dehydrogenase as a formate hydrogenlyase (FHL). This FHL complex generates H2 and CO2 from the disproportionation of formate (CHOO- + H+ ↔ H2 + CO2). In this Thesis, genetic and biochemical characterisation of Pectobacterium atrosepticum SCRI1043, a potato pathogen, led to the identification of a novel FHL complex. The [NiFe]-hydrogenase in this organism is similar to that of Escherichia coli Hydrogenase-4, with an extended membrane domain similar to that of respiratory Complex I. Importantly, the P. atrosepticum formate dehydrogenase is selenium-free, while previously characterised FHL complexes have selenocysteine-containing formate dehydrogenases. Using genetic and biochemical approaches it was shown that the [NiFe]-hydrogenase and a formate dehydrogenase were vital for H2 production by P. atrosepticum. Using plant infection assays it was also shown that the gene encoding the formate dehydrogenase was important for full infective ability of P. atrosepticum in potato plants and tubers. The latter part of this Thesis focuses on developing genetic tools to study this novel FHL from P. atrosepticum as well as Hydrogenase-1 and -2 from E. coli.

Prices ending in 9 are ubiquitous. In this paper I first develop a theoretical model of the effect of such prices on sales and review the empirical literature on the topic. Then I use a data set from an online experiment run by Lau (2000) to conduct an empirical study of the effect. Analysis with a logit model indicates that products with 9-ending prices are more likely to be chosen than others but a high fraction of 9-endings decreases the effect.

Full textAbstract:
La serie des registres du consistoire protestant de nimes constitue une source documentaire exceptionnelle par son etendue (1561-1685) et son homogeneite. L'application d'une methode serielle de depouillement revele au travers des mutations de l'activite consistoriale la vitalite du protestantisme nimois. L'organisation du culte comme la gestion materielle n'occupent qu'une place reduite parmi les cas traites au fil des deliberations. Le temple de la calade l'un des plus grands de france temoigne par sa taille de l'importance du protestantisme a nimes. L'eglise est desservie par quatre pasteurs aides des professeurs en theologie de l'academie; orthodoxie et qualite sont leurs principales caracteristiques. Ils font partie integrante de l'assemblee consistoriale, composee de douze anciens et six diacres exercant principalement les "etats" de marchands et "bourgeois". L'application de la censure morale et ecclesiastique est l'activite dominante jusques dans le premier tiers du xviie siecle; un ordre specifiquement protestant est mis en place grace a l'appui des pouvoirs civils urbains. A l'efficacite de la pacification de la societe repond l'echec de la lutte contre la danse et la persistance des relations avec les catholiques et leur eglise par nombre de fideles. Dans la seconde moitie du xviie siecle lorsque le pouvoir civil echappe aux protestants, apres deux decennies de desarroi le consistoire s'applique essentiellement a l'organisation et la distribution de l'assistance charitable. Le pouvoir economique de ses membres prend le relais; la richesse du commerce nimois sous-tend la vitalite reformee dont temoigne la courbe des conversions. La tentative d'integration dans l'ordre social du royaume par une conduite soumise et fidele au monarque preside desormais, elle determine l'action consistoriale en matiere de defense de l'eglise vers des voies pacifiques. L'influence du consistoire organe dirigeant de l'une des trois principales eglises de la province synodale depasse le cadre urbain, il coordonne et organise la lutte pour l'existance de celles qui l'avoisinent.
