Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN.

Being in between: An Ethnographic Study of Opera and Dialogical Identity Construction

The paradoxical co-existence of conflicting logics governs practices in cultural organizations. This requires ‘balancing acts’ between artistic and managerial efforts, which are often subjects to struggle among the organizational members. This ethnographic study aims to go beyond either-or thinking on the paradoxical organizational context by examining how the organizational members of an opera house construct views on their organization in dialogical meaning-making processes. Various professional groups, dozens of upcoming productions, increased international cooperation, and global competition combined with scarce financial resources make opera houses a complex though interesting context for organization studies. In order to provide a deeper knowledge of the internal dynamics of an opera organization this thesis takes an interpretative view to examine the ways organizational members construct and make sense of their organization. How is the opera organization constructed by the organizational members? How do the members draw on different logics when relating to their organization? Or what are the elements that characterize the relational processes of organizational identity construction in an opera organization? The thesis aims to answer these questions by providing a detailed description of the everyday life of an opera organization and a particular focus put on organizational identity construction. The processes of organizational identity construction are approached from a relational point of view. This may involve various relations between multiple positions, different professional groups, other organizations in the cultural field or between past and present understandings of an organization. The study shows that the construction of an opera organization involves not only the two conflicting logics of art and economy, but also the logic of a national institution. The study suggests also that organizational identities are constructed through processes related to the dialogics of positions, work and management practices. The dialogics involve various struggles through which the organizational members find themselves between the different organizational aspects such as visiting ‘stars’ and an ensemble or between ‘Finnishness’ of opera productions and internationalization. In addition, the study argues that a struggle between different elements is a general mode of relation in cultural organizations and therefore an inherent and enduring aspect in the organizational identity construction. However, the space of ‘being in between’ involves both the enabling and constraining elements in the dialogical identity construction in the context of cultural organizations, which present the struggle in a more generative light.

Research note A novel BIMOS Schmitt trigger

A new Schmitt trigger circuit based on the lambda bipolar transistor is presented. This circuit which exhibits a hysteresis in its transfer characteristic seems to use a smaller chip area than many of the circuits proposed so far.

Intracellular Pathogen Sensor NOD2 Programs Macrophages to Trigger Notch1 Activation

Intracellular pathogen sensor, NOD2, has been implicated in regulation of wide range of anti-inflammatory responses critical during development of a diverse array of inflammatory diseases; however, underlying molecular details are still imprecisely understood. In this study, we demonstrate that NOD2 programs macrophages to trigger Notch1 signaling. Signaling perturbations or genetic approaches suggest signaling integration through cross-talk between Notch1-PI3K during the NOD2-triggered expression of a multitude of immunological parameters including COX-2/PGE(2) and IL-10. NOD2 stimulation enhanced active recruitment of CSL/RBP-Jk on the COX-2 promoter in vivo. Intriguingly, nitric oxide assumes critical importance in NOD2-mediated activation of Notch1 signaling as iNOS(-/-) macrophages exhibited compromised ability to execute NOD2-triggered Notch1 signaling responses. Correlative evidence demonstrates that this mechanism operates in vivo in brain and splenocytes derived from wild type, but not from iNOS(-/-) mice. Importantly, NOD2-driven activation of the Notch1-PI3K signaling axis contributes to its capacity to impart survival of macrophages against TNF-alpha or IFN-gamma-mediated apoptosis and resolution of inflammation. Current investigation identifies Notch1-PI3K as signaling cohorts involved in the NOD2-triggered expression of a battery of genes associated with anti-inflammatory functions. These findings serve as a paradigm to understand the pathogenesis of NOD2-associated inflammatory diseases and clearly pave a way toward development of novel therapeutics.

Time delay to firing of a triggered vacuum gap with barium titanate in trigger gap

The time delay to the firing of a triggered vacuum gap (t.v.g.) containing barium titanate in the trigger gap is investigated as a function of the main gap voltage, main gap length, trigger pulse duration, trigger current and trigger voltage. The time delay decreases steadily with increasing trigger current and trigger voltage until it reaches saturation. The effect of varying the main gap length and voltage on the time delay is not strong. Before `conditioning�¿ the t.v.g. two groups of time delays, long (>100�¿s) and short (<10�¿s), are simultaneously observed when a large number of trials are conducted. After conditioning, only the group of short time delays are present. This is attributed to the marked reduction of the resistance of the trigger gap across the surface of the solid dielectric resulting directly from the conditioning effect.

NDK Interacts with FtsZ and Converts GDP to GTP to Trigger FtsZ Polymerisation - A Novel Role for NDK

Introduction Nucleoside diphosphate kinase (NDK), conserved across bacteria to humans, synthesises NTP from NDP and ATP. The eukaryotic homologue, the NDPK, uses ATP to phosphorylate the tubulin-bound GDP to GTP for tubulin polymerisation. The bacterial cytokinetic protein FtsZ, which is the tubulin homologue, also uses GTP for polymerisation. Therefore, we examined whether NDK can interact with FtsZ to convert FtsZ-bound GDP and/or free GDP to GTP to trigger FtsZ polymerisation. Methods Recombinant and native NDK and FtsZ proteins of Mycobacterium smegmatis and Mycobacterium tuberculosis were used as the experimental samples. FtsZ polymersation was monitored using 90 degrees light scattering and FtsZ polymer pelleting assays. The gamma 32P-GTP synthesised by NDK from GDP and gamma 32P-ATP was detected using thin layer chromatography and quantitated using phosphorimager. The FtsZ bound P-32-GTP was quantitated using phosphorimager, after UV-crosslinking, followed by SDS-PAGE. The NDK-FtsZ interaction was determined using Ni2+-NTA-pulldown assay and co-immunoprecipitation of the recombinant and native proteins in vitro and ex vivo, respectively. Results NDK triggered instantaneous polymerisation of GDP-precharged recombinant FtsZ in the presence of ATP, similar to the polymerisation of recombinant FtsZ (not GDP-precharged) upon the direct addition of GTP. Similarly, NDK triggered polymerisation of recombinant FtsZ (not GDP-precharged) in the presence of free GDP and ATP as well. Mutant NDK, partially deficient in GTP synthesis from ATP and GDP, triggered low level of polymerisation of MsFtsZ, but not of MtFtsZ. As characteristic of NDK's NTP substrate non-specificity, it used CTP, TTP, and UTP also to convert GDP to GTP, to trigger FtsZ polymerisation. The NDK of one mycobacterial species could trigger the polymerisation of the FtsZ of another mycobacterial species. Both the recombinant and the native NDK and FtsZ showed interaction with each other in vitro and ex vivo, alluding to the possibility of direct phosphorylation of FtsZ-bound GDP by NDK. Conclusion Irrespective of the bacterial species, NDK interacts with FtsZ in vitro and ex vivo and, through the synthesis of GTP from FtsZ-bound GDP and/or free GDP, and ATP (CTP/TTP/UTP), triggers FtsZ polymerisation. The possible biological context of this novel activity of NDK is presented.

Vita, et fatti dell'invitissimo imperatore Carlo Qvinto, et historie universali del mondo, de' suoi tempi... opera vitilissima a prencipi, signori, & capitani, & qual si voglia persona che d'historie si diletta composta dal Sig. Alfonso Ulloa, con la Pace, & Capitolationi seguite, tra li due potentissimi Prencipi Di Francia, & Spagna : & Con Toaule Copiosissime : & In questa ultima qditione in molti moughi mccresciuta, & migliorata

Afonso de Ulloa, escritor espanhol, nasceu em Zamora na primeira metade do século XVl e morreu em Veneza, Itália, em 1580. Filho de Francisco de Ulloa, oficial que esteve na África com Carlos V, seguiu também a carreira das armas, estabelecendo-se depois em Veneza. Desempenhou várias missões diplomáticas, escreveu muitas obras e traduziu para o italiano, língua que conhecia tanto quanto a materna, autores espanhóis e portugueses. Quanto à obra Vita, et fatti dell' invitissimo imperatore Carlo Qvinto.. . sabe-se que foi pela primeira vez impressa em Veneza em 1560 por Vincenzo Valgrisio e que foi muitas vezes reeditada. Salvo pela época, a edição supra referenciada não oferece grande interesse artístico, mas há uma interessante gravura com a efígie de Carlos V.

Explicação do salmo cincoenta feita a rogo da madre Dona Isabel de Sancto Antonio, ou de Lima, pello P. Fr. Pedro de S. Francisco frade menor da Provincia de Portugal : Dico ego opera mea

Pedro de S. Francisco nasceu em Marzagào, na África, em data desconhecida, e morreu em 1638. O religioso franciscano foi mestre em Teologia e Provincial da sua Ordem. Segundo Inocêncio, na ‘Explicação do salmo cincoenta’, o autor analisa e comenta extensamente cada um dos versos do salmo Miserere mei Dei e afirma, ainda, que "são raros os exemplares deste livro, em que (corno diz o censor Jorge Cabral, que o reviu por ordem do Santo Ofício) resplandece a erudição, doutrina, piedade e sabedoria do autor". O impressor da obra, Pedro Craesbeeck, nasceu em Antuérpia, onde aprendeu a arte da impressão na famosa Oficina de Cristóvão Plantino. Mudou-se para Portugal por volta de 1592, onde fundou uma verdadeira dinastia de impressores célebres que ali trabalharam nos séculos XV e XVI. Responsável pela impressão de obras de grande beleza tipográfica. Pedro Craesbeeck tornou-se impressor régio, conforme consta em alvará de 28 de maio de r620. Seus trabalhos foram editados no período de 1597 a 1632.

Ca2+ Influx and Tyrosine Kinases Trigger Bordetella Adenylate Cyclase Toxin (ACT) Endocytosis. Cell Physiology and Expression of the CD11b/CD18 Integrin Major Determinants of the Entry Route

Humans infected with Bordetella pertussis, the whooping cough bacterium, show evidences of impaired host defenses. This pathogenic bacterium produces a unique adenylate cyclase toxin (ACT) which enters human phagocytes and catalyzes the unregulated formation of cAMP, hampering important bactericidal functions of these immune cells that eventually cause cell death by apoptosis and/or necrosis. Additionally, ACT permeabilizes cells through pore formation in the target cell membrane. Recently, we demonstrated that ACT is internalised into macrophages together with other membrane components, such as the integrin CD11b/CD18 (CR3), its receptor in these immune cells, and GM1. The goal of this study was to determine whether ACT uptake is restricted to receptor-bearing macrophages or on the contrary may also take place into cells devoid of receptor and gain more insights on the signalling involved. Here, we show that ACT is rapidly eliminated from the cell membrane of either CR3-positive as negative cells, though through different entry routes, which depends in part, on the target cell physiology and characteristics. ACT-induced Ca2+ influx and activation of non-receptor Tyr kinases into the target cell appear to be common master denominators in the different endocytic strategies activated by this toxin. Very importantly, we show that, upon incubation with ACT, target cells are capable of repairing the cell membrane, which suggests the mounting of an anti-toxin cell repair-response, very likely involving the toxin elimination from the cell surface.

Megaeventos e direito à moradia: como opera o empreendedorismo urbano no contexto do neodesenvolvimentismo. O caso do Parque Olímpico no Rio de Janeiro

Esta pesquisa busca investigar um processo em curso, onde a estratégia do empreendedorismo na gestão das políticas públicas urbanas vem se adaptando e se conformando ao atual contexto de política econômica chamada de neodesenvolvimentismo. Para isso, as parcerias público-privadas tem um papel fundamental na gestão do desenvolvimento urbano, no âmbito das três esferas de poder. Abordaremos, portanto, o histórico das reformas políticas do País que levaram a uma evolução da política de nacional-desenvolvimentismo ao novo desenvolvimentismo, para entendermos o contexto no qual as atuais parcerias público-privadas vem sendo desenvolvidas como modelo para de gerir o território. Mencionaremos também a legislação e os discursos por trás da defesa deste tipo de negócio entre o poder público e o setor privado. Ainda, como o país enfrentou a crise de 2008, chamada de crise das crises, utilizando esse modelo de gestão do território. Os megaeventos esportivos serão analisados como um fator catalizante da atração de investimentos e negócios para as cidades. No Rio de Janeiro, com a escolha da cidade para sediar os Jogos Olímpicos, e também sendo uma das cidades sedes da Copa do Mundo FIFA de 2014, várias de transformações territoriais se iniciaram. Com fortes indícios de que uma série de violações estava por vir, a fim de abrir espaço e ampliar o mercado dos investimentos privados. O Parque Olímpico, como principal local de competições das Olimpíadas de 2016, configura-se como uma imensa oportunidade de negócios com a iniciativa privada, localizado em área de ampla expansão do mercado imobiliário da cidade: a Barra da Tijuca. Diante disso, muitas comunidades pobres vem sofrendo com a política de deslocamento forçado para dar lugar aos investimentos no território. Neste contexto, está a comunidade Vila Autódromo, estabelecida bem ao lado do local de implementação do empreendimento. Sua remoção está prevista no estudo de viabilidade e no edital de concessão. Estudaremos a parceria público-privada realizada para a construção do Parque Olímpico, através da análise dos documentos relacionados ao seu processo licitatório e a escolha do consórcio vencedor. Ainda, como esse empreendimento tem impactado no caso da comunidade Vila Autódromo, que além de já ter sido alvo de outras tentativas de remoção, foi objeto de uma política de regularização fundiária no passado e tem um intenso histórico de resistência e de luta pela permanência.
