The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

Hermenêutica existencial em Agostinho de Hipona e Martin Heidegger

The thesis presents interpretations of Augustine of Hippo with regard to the first three chapters of genesis, the first book of the Bible. These interpretation are found in the works Literal Commentary on Genesis, concerning Genesis Against the Manicheans, Literal Commentary on Genesis, Unfinished, Books Xi-XIII of the Confessions, as well a brief exposition in Books XI-XIV of the City of God. Exposition of these Augustinian Commentaries seeks to demonstrate various interpretations made by author in one group of texts revealing a hermeneutics centered in the interpreter and not in established interpretive rules. In sequence there is described succinctly the evolution of textual hermeneutics during the modern period up to the reflections conducted by Martin Heidegger in the first half of the twenties. Based in Heidegger s existential commentaries on the Pauline Epistles (Galatians and I-II Thessalonians) and on the tenth Book of the Confessions, there is shown a return to a interpreter-based hermeneutics, such as practiced by Augustine. The concern manifested by Heidegger with regard to given bases foundations, existent in Dasein, foundations which can influence self-comprehension, constitute themselves in possibilities of explication as much for Augustinian interpretive variations, as for the existential approach applied by Heidegger to the Pauline epistles and Augustine s text

O lugar no espaço: de Martin Heidegger para Eduardo Chillida

In preparing the book Art and Space - originally titled Die Kunst und der Raum (1969) - together with the work of Eduardo Chillida, and devote the text written to the sculptor, Heidegger seems to see in the works of Chillida some of his key themes rescued and reunited. This fusion of content and thought was revealed in his dialogue, at another moment, with the poetry of Friedrich Hölderlin. This dissertation aims to present some of the fundamental concepts in Heidegger's work, especially space, place and art; as well as explain the dialogue between these concepts and the works and thoughts of the sculptor Eduardo Chillida. Amongst the main points of this convergence of thought between the philosopher and the sculptor, we can find: the definition of art; the relationship of world and earth; the thinking about the place of art nowadays; and the meanings of interspace, to incorporate and make the space positive

Measurement of the B-s(0) lifetime in the exclusive decay channel B-s(0)-> J/psi phi

Using the exclusive decay B-s(0)-->J/psi(mu(+)mu(-))phi(K+K-), we report the most precise single measurement of the B-s(0) lifetime. The data sample corresponds to an integrated luminosity of approximately 220 pb(-1) collected with the D0 detector at the Fermilab Tevatron Collider in 2002-2004. We reconstruct 337 signal candidates, from which we extract the B-s(0) lifetime, tau(B-s(0))=1.444(-0.090)(+0.098)(stat)+/-0.020(sys) ps. We also report a measurement for the lifetime of the B-0 meson using the exclusive decay B-0-->J/psi(mu(+)mu(-))K-*0(892)(K(+)pi(-)). We reconstruct 1370 signal candidates, obtaining tau(B-0)=1.473(-0.050)(+0.052)(stat)+/-0.023(sys) ps, and the ratio of lifetimes, tau(B-s(0))/tau(B-0)=0.980(-0.071)(+0.076)(stat)+/-0.003(sys).

The upgraded DO detector

The DO experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid -argon calorimeters and central muon detector, remaining from Run 1, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DO. (c) 2006 Elsevier B.V. All rights reserved.

Measurement of dijet azimuthal decorrelations at central rapidities in p(p)over-bar collisions at root s=1.96 TeV

Correlations in the azimuthal angle between the two largest transverse momentum jets have been measured using the D0 detector in p (p) over bar collisions at a center-of-mass energy root s=1.96 TeV. The analysis is based on an inclusive dijet event sample in the central rapidity region corresponding to an integrated luminosity of 150 pb(-1). Azimuthal correlations are stronger at larger transverse momenta. These are well described in perturbative QCD at next-to-leading order in the strong coupling constant, except at large azimuthal differences where contributions with low transverse momentum are significant.

Observation and properties of the X(3872) decaying to J/psi pi(+)pi(-) in p(p)over-bar collisions at root s=1.96 TeV

We report the observation of the X(3872) in the J/psipi(+)pi(-) channel, with J/psi decaying to mu(+)mu(-), in p (p) over bar collisions at roots=1.96 TeV. Using approximately 230 pb(-1) of data collected with the Run II D0 detector, we observe 522+/-100 X(3872) candidates. The mass difference between the X(3872) state and the J/psi is measured to be 774.9+/-3.1(stat)+/-3.0(syst) MeV/c(2). We have investigated the production and decay characteristics of the X(3872) and find them to be similar to those of the psi(2S) state.

Search for doubly charged Higgs boson pair production in the decay to mu(+)mu(+)mu(-)mu(-) in p(p)over-bar collisions at root s=1.96 TeV

A search for pair production of doubly charged Higgs bosons in the process p (p) over bar -->H++H---->mu(+)mu(+)mu(-)mu(-) is performed with the D0 run II detector at the Fermilab Tevatron. The analysis is based on a sample of inclusive dimuon data collected at an energy of roots=1.96 TeV, corresponding to an integrated luminosity of 113 pb(-1). In the absence of a signal, 95% confidence level mass limits of M(H-L(+/-+/-))>118.4 GeV/c(2) and M(H-R(+/-+/-))>98.2 GeV/c(2) are set for left-handed and right-handed doubly charged Higgs bosons, respectively, assuming 100% branching into muon pairs.

Search for supersymmetry with gauge-mediated breaking in diphoton events at D0

We report the results of a search for supersymmetry (SUSY) with gauge-mediated breaking in the missing transverse energy distribution of inclusive diphoton events using 263 pb(-1) of data collected by the D0 experiment at the Fermilab Tevatron Collider in 2002-2004. No excess is observed above the background expected from standard model processes, and lower limits on the masses of the lightest neutralino and chargino of about 108 and 195 GeV, respectively, are set at the 95% confidence level. These are the most stringent limits to date for models with gauge-mediated SUSY breaking with a short-lived neutralino as the next-to-lightest SUSY particle.

Comunidade e eticidade: uma contribuição à aventura sociológica no pensamento de Martin Buber

Nossa investigação deve fazer uma reflexão sobre o conceito de Comunidade em M. Buber, tentando aproximá-lo de uma perspectiva a qual podemos denominar Eticidade, considerando sua respectiva contribuição: a Dialogia, como fonte central de qualquer relação humana. Trataremos aqui especificamente a forma como autor aborda o tema da Comunidade em confronto com o mundo moderno e suas forças despersonalizante e anônimas, sobre as quais, temos um indivíduo sem morada. Para isso, nos valeremos das contribuições dos clássicos da sociologia, tais como: Tönnies, Durkheim e Weber. Desta forma, tentaremos avançar num segundo momento, analisando a Comunidade na Modernidade líquida, a partir das orientações teóricas de Zigmunt Bauman. Neste vislumbraremos a inviabilidade da comunidade numa sociedade onde a individualidade e a identidade são fluidas, e as únicas formas de comunidades existentes não passam de comunidades de solitários. Contudo, partiremos para o momento que consideramos decisivo em nossa análise, faremos uma reflexão sobre a perspectiva dialógica de comunidade, no intuito de abrirmos caminhos para uma reflexão mais antropológica e fenomenológica do conceito, e, principalmente, trazendo à sociologia, a importante contribuição do pensamento de Martin Buber. Sua perspectiva aponta para a Comunidade como um caminho de diálogo, de reconhecimento do outro, bem como, de realização da pessoa no espaço público. Nisto consiste nossa a contribuição à aventura sociológica no que concerne ao tema da comunidade.

Guimarães Rosa e Martin Heidegger: duas visões sobre o Nazismo

No ano de 1970 houve a publicação da obra póstuma Ave, palavra de Guimarães Rosa (1908-1967) que reúne alguns textos do autor, desta coletânea de textos se faz a escolha das crônicas “O mau humor de Wotan”, “A velha” e “A senhora dos segredos”, que giram em torno do contexto do Nazismo alemão e expõem uma posição contraria ao Nacional Socialismo. Num primeiro momento o trabalho busca mostrar como Benedito Nunes (1929-2011) se guiou por uma tendência interpretativa concebida por comentadores heideggerianos antes das obras completas [Gesamtausgabe] (2001), tal tendência postula que não há na Filosofia de Martin Heidegger (1889-1976) um vínculo entre o pensamento político e o filosófico. O passo seguinte expõe a noção heideggeriana em Ser e Verdade (2001) em que o filósofo alemão propõe uma fundamentação ideológica para o Nazismo, sendo favorável a este com certas ressalvas. Assim, mostra-se como as obras completas expõem argumentos que apontam uma limitação em relação aos comentadores que produziram antes de sua publicação sobre a Política e a Filosofia em Heidegger. No subcapítulo sobre O local da diferença (2005), trata-se do trauma e do testemunho como conceitos centrais que o autor coloca para teorizar as Literaturas do século XX nos contextos de guerra e de regimes autoritários. Após, faz-se uma leitura crítica com base na premissa do pensamento político filosófico em Heidegger nas crônicas rosianas, pois estas expõem imagens do período da Alemanha nazista que o escritor mineiro esteve como diplomata. A segunda crítica das crônicas de guerra será feita com base nos conceitos de trauma e de testemunho formulados por Seligmann-Silva (1964), pois, as obras rosianas tratadas demonstram o teor de autoritarismo do partido nazista. Por fim, será feita uma definição do conceito de recepção de Hans Robert Jauss (1921-1997) para em seguida discutir os autores que fizeram a recepção críticas das crônicas rosianas.
