The decay of 94 day ¹⁸⁵Os to levels in ¹⁸⁵Re has been studied, using Ge(Li), NaI(Tl), and Si(Li) detectors. The internal conversion spectrum was investigated using the Chalk River 𝛑√2 β-spectrometer. The decay scheme is discussed and some spin assignments are suggested. / Thesis / Master of Science (MSc)

With the fast-approaching limits of single-threaded CPU performance, chip vendors are manufacturing an array of radically different computing architectures, including multicore and heterogeneous architectures, to continue to accelerate computer performance. An important emerging data point in the heterogeneous architecture design space is heterogeneity in instruction-set architecture (ISA). ISA-heterogeneity is emerging in many forms. An exemplar case is Smart I/O devices such as SmartNICs and SmartSSDs that incorporate CPUs of the RISC ISA family (e.g, ARM64, RISC-V), which when integrated with a highperformance server with CPUs of the CISC ISA family (e.g., x86-64) yields a single machine with heterogeneous-ISA CPUs. This thesis presents the design of a shared memory OS for a cache-coherent, shared memory heterogeneous-ISA hardware. The OS, called ZxOS, is built by modifying the open-source ZephyrOS, including its architecture-specific code and page mapping mechanism to create a memory region that can be shared across heterogeneous- ISA CPUs. Since existent heterogeneous-ISA hardware has physically discrete memory for ISA-heterogeneous CPUs, ZxOS targets a software emulation environment that emulates cache-coherent, shared memory heterogeneous-ISA hardware. Our experimental evaluation using a set of micro- and macro-benchmarks demonstrate ZxOS's functionality. In particular, they show that a multithreaded application's threads can be split across (simulated) ISA-heterogeneous cores for parallel execution and that thread's concurrent access of shared memory variables is consistent. / Master of Science / The computing industry saw a growing difficulty with power management and heat dissipation in single-core CPUs with high clock speeds. Chip vendors adapted multi-core chip strategy because it improved power and performance characteristics. This idea evolved into heterogeneous computing paradigm, which uses heterogeneous instruction-set-architecture(ISA) cores in a single system. Many server-grade specialized devices were provided with RISCbased general-purpose CPU to efficiently manage requests from the server. SmartNICs and SmartSSDs are the best examples of these smart devices. When integrated with generally present CISC(x86_64) processors in server space, these devices resulted in machine-level heterogeneous-ISA CPUs. This thesis presents a novel design of a shared memory OS for a cache-coherent, shared memory heterogeneous-ISA hardware. The OS, called ZxOS, is built by extending the ZephyrOS. Many of the architecture-specific codes were modified to create a memory region that can be shared across the cores. ZxOS is aimed at a software emulation environment for cache-coherent, shared memory heterogeneous-ISA systems. ZxOS has demonstrated the capability to run multi-threaded applications in a split fashion across heterogeneous-ISA cores. The heterogeneous-ISA cores execute threads parallelly, and the thread's shared memory interactions were observed to be consistent.

This study is focused on a bacular development in Microtus arvalis, histological sections in two species of voles for the detection of a presence of os clitoridis, and description of an os clitoridis in Sciurus vulgaris. in the last part, there is the penile morphology and bacular structure of one species of African mole rat (Heliophobius argenteocinereus) described.

Les os constituent une part importante du corps humain. Ils sont sollicités tout au long de la vie : ceci expose les différents os à une multitude de traumatismes. La correction des traumatismes osseux est un problème de tous les jours pour les chirurgiens orthopédiques et maxillo-faciaux. Malgré toutes les connaissances actuelles en chirurgie osseuse, il existe encore plusieurs limitations en rapport avec la guérison post-chirurgicale des greffes autogènes. La régénération osseuse à partir des facteurs de croissance pourrait venir en aide à la médecine moderne. L'objectif du présent travail est d'étudier l'effet des protéines de la morphogenèse de l'os (Bone Morphogenetic Proteins : BMPs) sur la régénération osseuse par de multiples expériences in vitro. Un modèle in vitro d'ingénierie osseuse a servi à comparer l'activité ostéogénique des BMPs, soit des homodimères de BMP-2 et de BMP-7 et de l'hétérodimère de BMP-2/BMP-7, pour étudier la croissance et la différenciation des ostéoblastes sur l'expression de l'ostéocalcine (OC), de l'interleukine-6 (IL-6), de la métalloprotéinase-2 (MMP-2) et de leurs inhibiteurs tissulaires TIMP-1 et TIMP-2. Notre approche expérimentale démontre que les homodimères de BMP-2 et BMP-7 ainsi que l'hétérodimère de BMP-2/BMP-7 favorisent la croissance des ostéoblastes et la production d'OC via l'lL-6. Aussi, comme les homodimères et l'hétérodimère, les deux protéines BMP-2 et BMP-7 stimulent la production de la matrice extracellulaire par l'inhibition de la production des MMPs via les TIMPs.

[pt] O gosto da luta. Os sertões como estratégia de construção teatral propõe um olhar sobre A luta (2005-2006), última parte do espetáculo em movimento Os sertões, transcriação do livro de Euclides da Cunha realizada por José Celso Martinez Corrêa. A investigação situada no contexto de resistência do Teatro Oficina contra a especulação imobiliária no Bairro do Bixiga, em São Paulo, focaliza a encenação de Os sertões como metáfora estratégica de reivindicação da construção de um teatro de estádio - idealizado por Oswald de Andrade - contaminando o projeto de criação de uma Universidade Popular Brazyleira Orgiástica, embrionariamente materializada no Projeto Bixigão´. Além da ótica sistêmica da encenação, a moldura teórica escolhida aborda A luta acentuando a materialidade e performatividade do espetáculo e seus efeitos de presença, propondo trânsitos disciplinares na construção de formas e sentidos alternativos que permitem lidar com experiências teatrais na contemporaneidade, freqüentemente rotuladas de pós-modernas. Além do diálogo com pressupostos teóricos desenvolvidos pela ciência da literatura empírica, a partir das contribuições de Siegfried Schmidt, que permitem abordar o espetáculo teatral como ação situada não apenas no sistema teatral e artístico atual, mas como ação complexa cujo efeito se expande na esfera social, serão exploradas também as premissas teóricas e experiências práticas do teórico da cultura Hans Ulrich Gumbrecht e do teórico e performer Johannes Birringer. / [en] The taste of A luta. Os sertões as a strategic theatrical construction proposes an observation on A luta (2005-2006), the last part of the moving play by José Celso Martinez Corrêa, Os sertões, a trans-criation from the Euclides da Cunha s book. This study is placed in the context of resistance, in which Teatro Oficina is located against the real-estate speculation in the Bixiga area, in São Paulo, and it focus the play Os sertões as a strategic metaphor to build a Teatro de Estádio - idealized by Oswald de Andrade - motivating the project of a Universidade Popular Brazyleira Orgiástica, whose Projeto Bixigão is an embryonic materialization. Beyond the systemic perspective over the theatrical performance, the chosen theoretical frame approaches A luta by emphasizing the materiality and performativity of the play and its presence effects, proposing disciplinary transits in the construction of alternative forms and senses which permit to deal with theatrical experiences, frequently labeled as post- moderns, nowadays. The contributions of Siegfried Schmidt permit to approach the theatrical performance as an action placed not only in the actual theatrical and artistic system, but as a complex action whose effect expand itself in the social sphere. In addition to this dialogue with theoretical formulations developed by Empirical Science of Literature, will be also explored the theoretical premises and practical experiences by the cultural theorist Hans Ulrich Gumbrecht and by the theorist and performer Johannes Birringer.

Ein Os akromiale ist das seltene Ergebnis einer fehlerhaften bzw. ausgebliebenen Verschmelzung der Epiphyse des anterioren Anteils des Akromions. Die Häufigkeit eines Os akromiale in der Literatur reichen von 1,3 -15%. Das Ziel der Arbeit war letztlich zu zeigen, inwiefern ein Os akromiale als Kofaktor einer Rotatorenmanschettenruptur angesehen werden kann. Dafür untersuchten wir die Rötgenaufnahmen von 1000 Patienten mit Ruptur der Rotatorenmanschette auf das Vorhandensein eines Os akromiale. Außerdem wurden 1000 Schultern eines Normalkollektivs ohne Schultererkrankung (mittels Ultraschall) ebenfalls auf das Vorhandensein eines Os akromiale untersucht. Es zeigte sich, dass ein Os akromiale bei Patienten mit Ruptur der Rotatorenmanschette mit einer Inzidenz von 6,2 %, bei asymptomatischen Probanden mit einer Häufigkeit von 3,3 % auftritt. Folglich kann das Os akromiale als Kofaktor bei der Entstehung einer Rotatorenmanschettenruptur angesehen werden. / An os acromiale is a rare anatomical condition and the result of a failed fusion of the anterior part of the acrmion. The incidence in literature ranges from 1,3 to 15 %. The purpose of this study was to investigate, whether an os acromiale can be judged as a co-condition in rotator cuff tears. Therefore we assessed the radiographs for the presence of os acromiale in 1000 patients with tear of the rotator cuff. Furthermore we assessed 1000 shoulders of a normal population without shoulder disease (via ultrasound) for the presence of an os acromiale. We found, that in patients with tear of the rotator cuff the incidence of an os acromiale was 6,2% compared to 3,3% in the population without shoulder diseases. Consequently an os acromiale must be judged as a co-condition in rotator cuff tears.
