mixtures of benzene with pyridine, piperidine, furon and tetrahydrofuron have
been estimated experimentally with different compositions at temperature 298 K.
These values are also calculated theoretically, based on free length theory as
revised recently by Kalidoss. It has been observed that there is a close
agreement with experimental results. The shape and thermostatic state picture built
up in this formulation could be considered as a good representation of
molecular interactions.</span
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Identification and characterization of gcc8, a glucosinolate-related mutation of Arabidopsis thaliana
Full text linkGlucosinolate sind Schwefel und Stickstoff beinhaltenden Metabolite des sekundären Metabolismus in Pflanzen Verteidigungsmechanismuses gegen Fraßinsekten. Mutation zu identifizieren und fanden ein verfrühtes Stopcodon im ersten Exon des SULTR1;2 Gens.Bereits zuvor, wurden SULTR1;2 Mutanten auf ihre erhöhte Toleranz gegenüber Selenaten (sel Allele), toxischen Analoga des Sulfates. Wir konnten zeigen, dass die den sel Mutanten allelische gcc8 Linie ebenfalls diese Resitenz gegenüber Selenat bei zeitgleich niedriger Glucosinolatkonzentration aufwies. Wir beobachteten weiterhin, dass die typischen Markergene für Schwefelmangel in unseren Mutanten verstärkt expremiert wurden. So implizierte BGLU28, eine mutmaßliche β-Glucosidase (At2g44460), dass die Schwefelresorption ingcc8. Hierbei wiedersprachen unsere Experimente mit Doppelmutanten (gcc8 und bglu28-KO), sowie enzymatischer Degradation des Glucosinolat Bioassays, dass BGLU28 die Glucosinolate unter Schwefelmangelbedingungen abbaut.Glucosinolates are sulfur and nitrogen containing plant secondary metabolites involved in plant defense against insect herbivores. We identified the causative mutation for one of our earlier identified mutant gcc8 as premature stop codon in the first exon of SULTR1;2. Earlier, AtSULTR1;2 mutants identified for its tolerance to selenate (sel alleles), a toxic structural analogue of sulfate. As gcc8 line also allelic to sel mutants, shows resistance to selenate along with low glucosinolate content. We observed that, the typical sulfur deficiency marker genes were expressed higher in mutant background including, BGLU28 (putative β- glucosidase, At2g44460) which proves that sulfur uptake is blocked in gcc8. Our experiments with double mutant isolation of gcc8 and bglu28-KO and enzymatic degradation of glucosinolate bioassaystrongly reject the fact that BGLU28 could degrade the glucosinolates under sulfur starvation conditions rather it might be a secondary effect of sulfur deficiency.vorgelegt von Kalidoss Ramamoorth
Variations on the Author
Full text link“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 linkWe 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 linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
