    Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV

    No full text
    The prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

    First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

    Artful living and the eradication of worry in Søren Kierkegaard's interpretation of Matthew 6:24-34

    No full text
    Danish thinker Søren Kierkegaard published fourteen discourses, across four collections, on Matthew 6:24-34. The repeated readings of the biblical text, whose themes include the choice between God and mammon, worry, what it means to consider the birds and lilies, and how to seek first the kingdom of God, converge with Kierkegaard’s interest in anxiety, despair, worry, subjectivity, indirect communication, choice, the moment, and life before God. Accordingly, the discourses make connections with his larger works, elucidate frequently explored Kierkegaardian themes in recent scholarship, and contribute to his critique of nineteenth-century Copenhagen. Additionally, the collections present an interpretation of each verse and phrase of Matthew’s text and, held up against modern Matthew scholarship, they correlate with and contribute to Sermon on the Mount and New Testament studies. Kierkegaard’s reading of Matthew also holds implications for the practice of biblical interpretation as it promotes the importance of awareness of sin, interestedness, and appropriation as central to proper reading. His emphasis on Christ as the primary exemplar of Matthew’s text adds an additional Christological element to his hermeneutic. Furthermore, the discourses serve as spiritual treatises which provide the reader with theological terminology to help confront the problem of worry and suffering. In light of a human being’s distinctiveness as imago Dei, Kierkegaard elucidates ways an individual may respond artfully to the ongoing possibility of worry, a possibility which the discourses connect with Christian anthropology and external labels associated with possessions and status. The Matthew 6 discourses intimate Kierkegaard’s sympathy with classic Christian spirituality and, in combination with the cultural-ecclesiastical critique, the creative exegesis, and the in-depth analysis of the cause of and cure for worry, his work emerges as an excellent example of spiritual theology

    Antibacterial Properties of Nanoparticles: A Comparative Review of Chemically Synthesized and Laser-Generated Particles

    No full text
    Nanomaterials have recently received an enormous amount of attention from the scientific community due to their outstanding activity relative to bulk materials. This increase in activity relative to bulk materials can be attributed to the high surface area to volume ratio associated with nanoparticles. Nanoparticles have found applications in almost every field of science. Currently there is significant interest in the development of nanoparticles as antibacterial agents. This work is paramount due to the increasing number of antibiotic-resistant strains of bacteria. Nanoparticles can be synthesized using various methods, each with their own advantages and disadvantages, and the method is often chosen based on the intended application. This review will cover the most prevalent method, chemical-based reduction of salts, and a fairly new laser-based method that holds tremendous promise in nanoparticle synthesis. We conclude with a comparison of the antimicrobial activities of materials made via each method.Peer reviewe

    In the middle: factors affecting a black male's decision to join a traditionally white fraternity at a large diverse institution

    No full text
    The purpose of this qualitative study is to examine the pre-college factors, attitudes, and experiences of black men who joined traditionally white fraternities (TWFs) at large public predominantly white institutions (PWIs) over approximately the past four decades. These factors, with special emphasis on issues of identity, self- and group-esteem, and group salience when the individual’s environment changes, will be examined through the theoretical lens of Social Identity Theory. An integrated set of qualitative methods was used to gather data. Participants were asked to complete a brief online demographic survey, were provided an opportunity to journal about their experiences, engaged in a semi-structured interview with the primary researcher, and were asked follow up questions where necessary. Participants in this study de-emphasized their race as a factor in their identity and distanced themselves from a race-based fictive kinship due to both internal beliefs and external messages regarding negative stereotypes of blacks and black culture. Participants reported immersion in predominantly white social and academic experiences and environments, a comparative identification with white peers over blacks while maintaining a tenuous fictive kinship, and that membership in a traditionally white fraternity was consistent with their academic and social attitudes and priorities, while also acknowledging that full acceptance in white culture was elusive. Ultimately participants found themselves "in the middle;" navigating both worlds; not always fully accepted by whites while feeling disconnected from the views and attitudes of other blacks.Ed.

    Immunity-linked genes are stimulated by a membrane stress pathway linked to Golgi function and the ARF-1 GTPase

    No full text
    Infection response and other immunity-linked genes (ILGs) were first named in Caenorhabditis elegans-based expression after pathogen challenge, but many are also up-regulated when lipid metabolism is perturbed. Why pathogen attack and metabolic changes both increase ILGs is unclear. We find that ILGs are activated when phosphatidylcholine (PC) levels change in membranes of secretory organelles in C. elegans. RNAi targeting of the ADP-ribosylation factor arf-1, which disrupts the Golgi and secretory function, also activates ILGs. Low PC limits ARF-1 function, suggesting a mechanism for ILG activation via lipid metabolism, as part of a membrane stress response acting outside the ER. RNAi of selected ILGs uncovered defects in the secretion of two GFP reporters and the accumulation of a pathogen-responsive complement C1r/C1s, Uegf, Bmp1 (CUB) domain fusion protein. Our data argue that up-regulation of some ILGs is a coordinated response to changes in trafficking and may act to counteract stress on secretory function

    Matthew’s Emmanuel Messiah: a paradigm of presence for god's people

    No full text
    The motif of divine presence is a clear phenomenon within the Gospel of Matthew. The modern critical means for assessing the ancient biblical text have multiplied to the point, some claim, of disparity. This study employs both narrative and redaction criticism in an attempt to respond authentically to the structural, historical and theological dimensions of Matthew's Gospel. This study begins with the presumption of the wholeness and integrity of Matthew's narrative, and assumes the gospel story to have an inherently dramatic structure which invites readers to inhabit imaginatively its narrative world and respond to its call. But since we are concerned with the role of both reader and author, this study also assumes a text with an historical author and context. The introduction focuses on the meta-critical dilemma facing New Testament students - what is the text and how do we read it? - and seeks some balance in terms of Krieger's analogy of the text as both window and mirror. Proposed is a narrative reading of Matthew's presence motif alongside a redaction critical assessment of it. In Chapter 2 the elements of narrative theory are introduced and relevant terms defined: the structure of narrative, the function of the narrator, points of view. Chapter 3 becomes an exercise in narrative reading, with Matthew's presence motif providing the focus, and the implied reader’s interaction with the story being predominant in interpretation. Characters, rhetorical devices, and points of view are discussed, to understand the motif's development throughout the story's progress. The thrust of Chapter 4 is thereafter to examine divine presence as a dominant motif within Matthew's most important literary context: the Jewish scriptures. Here the primary paradigms of divine presence provided by the Patriarchs, the Sinai experience, and the Davidic-Zion traditions are assessed. Chapter 5 follows with a more detailed examination of the OT "I am with you/God is with us" formula and its µeo' vµwv/ηuwv language, so strongly connected to Matthew's presence motif. Chapters 6-8 build on these investigations with a closer analysis of the three critical "presence passages" of Mt 1:23. 18:20 and 28:20. The passages and their contexts are probed from a redaction critical perspective, guided by the narrative investigation of Chapter 3, and the background from Chapters 4 and 5.The three major "presence passages" examined in Chapters 6-8 are also complimented by a number of secondary issues: worship, wisdom, the Spirit and the poor in Matthew, and their relation to Jesus' divine presence. These are discussed in Chapter 9. Chapter 10 summarizes and looks briefly at some implications. Matthew' presence motif proves to be an important element of the Gospel’s rhetorical design, redactional strategy and Christology. The presence of Jesus, the Emmanuel Messiah, exhibited in his risen authority, becomes the focus of his people's hopes and experiences in the post-Easter world. What the presence of Yahweh was to his people. Jesus now provides in a new paradigm for his people - his followers, the little ones, the poor and the marginalized, from all nations
