    Draft whole-genome sequence of bacillus altitudinis strain b-388, a producer of extracellular rnase

    No full text
    Here, we present a draft genome sequence of Bacillus altitudinis strain B-388, including a putative plasmid. The strain was isolated from the intestine of Indian meal moth, a common pest of stored grains, and it is characterized by the production of extracellular RNase, similar to binase, which is of interest for comparative studies and biotechnology. © 2015 Shah Mahmud et al

    Kitap sanatları Türk Sanatı’nın oluşumundaki en önemli unsurlar arasında gösterilmektedir. Bu alanda verilmiş eserler, sanatımızın geçmişten günümüze ulaşabilmesi bakımından son derece etkili olmuştur. Şah Mahmud Nişâburî Albümü de, kitap sanatlarının uygulama alanlarından olan murakka’ yapımcılığının en mühim örnekleri arasında gösterilmektedir. Başta Şah Mahmud Nişâburî olmak üzere İranlı hattatların kıt’alarının yer aldığı bu albümün tezhiplenmesinin ve ciltlenmesinin Osmanlı Nakkaşhânesi’nde yapıldığı kabul edilmektedir. Albümde kıt’a formunun sıra dışı örnekleri bir arada toplanmıştır. Hem hat hem de tezhip sanatı açısından çok değerli ve aynı zamanda yol gösterici bir eser niteliği taşıyan albümdeki kıt’a formlarının farklılığı, değişik boyutlarda ve şekillerde koltuk alanlarının oluşumunu sağlamış ve bu durum tasarımdaki çeşitliliği de beraberinde getirmiştir. Bu makalede de, Şah Mahmud Nişâburî Murakkaı’nda yer alan birkaç örnek, koltuk tezhibi yönünden ele alınacak ve incelenecektir.The arts of book are one of the most important elements in the formation of Turkish art. The works which are given in this field have been highly influential in terms of our art to reach from past to the present. Shah Mahmud Nişâburî album is shown as one of the most important examples of album production which is application area of book arts. In this album, which contains calligraphic kıt’as of Persian calligraphers, mostly of Shah Mahmud Nişâburî, illumination and binding in Ottoman palace studio, kıt’a forms’ extraordinary examples are gathered together. The variety of kıt’a forms in the album, which is both valuable and at the same time an advisor in terms of calligraphy and illumination, has provided the formation of koltuk areas in different sizes and shapes and this brought diversity in the design. In this article, some samples in Shah Mahmud Nişâburî album will be analyzed in terms of koltuk illumination

    Ribonuclease from bacillus acts as an antiviral agent against negative- and positive-sense single stranded human respiratory RNA viruses

    Bacillus pumilus ribonuclease (binase) was shown to be a promising antiviral agent in animal models and cell cultures. However, the mode of its antiviral action remains unknown. To assess the binase effect on intracellular viral RNA we have selected single stranded negative- and positive-sense RNA viruses, influenza virus, and rhinovirus, respectively, which annually cause respiratory illnesses and are characterized by high contagious nature, mutation rate, and antigen variability. We have shown that binase exerts an antiviral effect on both viruses at the same concentration, which does not alter the spectrum of A549 cellular proteins and expression of housekeeping genes. The titers of influenza A (H1N1pdm) virus and human rhinovirus serotype 1A were reduced by 40% and 65%, respectively. A preincubation of influenza virus with binase before infection significantly reduced viral titer after single-cycle replication of the virus. Using influenza A virus mini genome system we showed that binase reduced GFP reporter signaling indicating a binase action on the expression of viral mRNA. Binase reduced the level of H1N1pdm viral NP mRNA accumulation in A549 cells by 20%. Since the viral mRNA is a possible target for binase this agent could be potentially applied in the antiviral therapy against both negative- and positive-sense RNA viruses.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
