Coordination complexes of copper(II) with herbicide-trichlorophenoxyacetate: Syntheses, characterization, single crystal X-ray structure and packing analyses of monomeric [Cu(γ-pic)3(2,4,5-trichlorophenoxyacetate)]·H2O, [trans-Cu(en)2(2,4,5-trichlorophenoxyacetate)2]·2H2O and dimeric [Cu2(H2tea)2(2,4,5-trichlorophenoxyacetate)2]·2(H2O)
No full textThree novel coordination complexes of copper(II) with 2,4,5-trichlorophenoxyacetate [Cu(γ-pic)3(L)2]·H2O 1, [trans-Cu(en)2(L)2]·2H2O 2 and [Cu2(H2tea)2(L)2]·2H2O 3, where L = 2,4,5-trichlorophenoxyacetate, γ-pic = γ-picoline, en = ethylenediamine, H2tea = monodeprotonated triethanolamine, were synthesized by addition of γ-picoline/ethylenediamine/triethanolamine, respectively, to the hydrated Cu(2,4,5-trichlorophenoxyacetate)2 suspended in methanol-water (4:1, v/v). The newly synthesized complexes have been characterized by elemental analyses, spectroscopic techniques (UV–Vis and FT-IR), magnetic moment determination, molar conductance studies, TGA and single crystal X-ray diffraction method. The structure determination revealed neutral nature of complexes in all the three cases, with different coordination geometry around the copper(II) metal centre depending upon nature of the N- or N,O-donor ligands. Hydrogen bonding network i.e. O–H⋯O and C–H⋯O in complexes 1, 3 and N–H⋯O, and O–H⋯O in complex 2 stabilizes crystal lattice in copper(II) complexes besides other non-covalent interactions
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
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

Chapter 8 - Lentil genome sequencing: Establishing a comprehensive platform for molecular breeding
No full textLentil (Lens culinaris Medik.) is an important cool season food legume crop. It has a large and complex genome. Sequencing of the genome is important to enrich lentil crops with genomic resources for molecular breeding. During past years considerable attention has been given to the sequencing of the lentil genome, which has led to the development of expressed sequence tags (ESTs), unigenes, transcripts, and sequences. Efforts have also been made to develop a whole genome sequence of lentils and a draft genome sequence of 3.69 Gb was developed as a reference genome for the future. These genome sequencing efforts have provided a comprehensive platform for molecular breeding in lentils. This chapter discusses the prospects of the lentil genome sequencing platform for revolutionizing genomic research and its use in genomic-assisted breeding in lentils
