A comon genomic framework for a diverse assembly of plasmids in the symbiotic nitrogen fixing bacteria
Get PDFThis work centres on the genomic comparisons of two closely-related nitrogen-fixing symbiotic bacteria, Rhizobium leguminosarum biovar viciae 3841 and Rhizobium etli CFN42. These strains maintain a stable genomic core that is also common to other rhizobia species plus a very variable and significant accessory component. The chromosomes are highly syntenic, whereas plasmids are related by fewer syntenic blocks and have mosaic structures. The pairs of plasmids p42f-pRL12, p42e-pRL11 and p42b-pRL9 as well large parts of p42c with pRL10 are shown to be similar, whereas the symbiotic plasmids (p42d and pRL10) are structurally unrelated and seem to follow distinct evolutionary paths. Even though purifying selection is acting on the whole genome, the accessory component is evolving more rapidly. This component is constituted largely for proteins for transport of diverse metabolites and elements of external origin. The present analysis allows us to conclude that a heterogeneous and quickly diversifying group of plasmids co-exists in a common genomic framework

Mecmû'a-i Eş'âr (06 Hk 3841)
No full textBu çalışmada Milli Kütüphane'de "06 Hk 3841" arşiv numarası ile kayıtlı Mecm?'a-i Eş'?r" adlı şiir mecmû'ası incelenmiştir. İlk başta mecmua hakkında bilgi verilmiş ve devamında şiirler yeni harflere aktarılmıştır, sonra vezin tespiti yapılmıştır. En son olarak da MESTAP tablosu oluşturulmuştur. Metnin okunduğu esnada daha önce yapılmış çalışmalardan da faydalanılmış ve karşılaştırma yapılmıştır.In this study, the poetry collection "Mecm?'a-i Eş'?r", registered with the archive number "06 Hk 3841" in the National Library, was examined. At first, information was given about majmua, and then the poems were transferred to new letters, and then their vezins were determined. The most recent MESTAP table has been created. During the reading of the text, previous studies were also used and comparisons were made
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Analysis of the ECF sigma factors of rhizobium leguminosarum biovar viciae 3841
No full textTo investigate the role of extracytoplasmic function sigma factors in the Rhizobium-legume symbiosis, the genome sequence of Rhizobium leguminosarum bivoar viciae 3841 was analysed using bioinformatics approaches. In total, twenty sigma factors were identified, including sixteen extracytoplasmic function sigma factors. Twelve of the sixteen ECF sigma factors appeared to be co-transcribed with a regulatory gene. The role of the ECF sigma factors in responding to legume produced compounds was investigated by growing strain 3841 containing various ecf reporter plasmids with pea root exudate. Three ECF sigma factors showed different expression patterns when grown with root exudate compared to minimal medium. One of the three sigma factor aenes. ecfR, which was induced by pea root exudates, was investigated further and was shown to be expressed in pea infection threads. Over-expression of ecfR was lethal to R. leguminosarum 3841, but co-expression with the adjacent gene, asfR, prevented the lethal effect.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
