Bis(acetato-κ2O,O′)bis(3,5-dimethyl-1H-pyrazole-κN2)copper(II)
No full textIn the title compound, [Cu(C2H3O2)2(C5H8N2)2], the CuII atom has a distorted tetragonal–bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu—O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated in cis positions with respect to each other. In the crystal structure, molecules are linked through intermolecular N—H...O hydrogen bonds, forming a one-dimensional chain

No full textThe asymmetric unit of the title compound, [Cu(CHO2)Cl(C5H8N2)3]2·[CuCl2(C5H8N2)2] or 2[A]·[B], contains one A molecule and one half-molecule of B, located on a centre of inversion. The CuII environments in A and B are different. In A, the CuII atom is coordinated by three N atoms from three 3,5-dimethyl-1H-pyrazole (L) ligands, one O atom from a formate ligand and a chloride anion in an axial position [Cu—Cl = 2.4275 (7) Å] in a distorted tetragonal–pyramidal geometry. The CuII atom in B is coordinated by two N atoms from two L ligands and two chloride anions [Cu—Cl = 2.2524 (6) Å] in a distorted square-planar geometry. In the crystal, intermolecular N—H...O hydrogen bonds link molecules A into centrosymmetric dimers. Intermolecular N—H...Cl hydrogen bonds further link these dimers with the B molecules, forming chains propagating in [101]
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

<p>Summary. Successful training of doctors in higher medical schools is associated with the searching for new effective forms of learning, one of which is problem-oriented learning. The purpose of the work was to improve the teaching methods in the study of propaedeutics of pediatrics on the basis of problem-oriented learning methods. According to the aim, the following tasks were solved: to implement interactive methods in the educational process; to intensify the creative activity of teachers and students in optimizing the educational process. Materials of the study were 2 groups of students: in the 1st group (28 students) used traditional methods of teaching, in the 2nd (also 28 students) - problem-oriented methods: method of situational learning, business game with problematic issues. The conducted research has led to the conclusion that problem-oriented learning leads to the formation of self-organization skills, self-study and self-control, that is, it increases the level of conscious attitude to the acquisition of professional knowledge, skills and personal qualities of the future doctor. This problem-oriented training is an important factor in the process of becoming a student as a specialist.</p>
<p>Key words: problem-oriented teaching, student, propaedeutics of pediatrics.</p
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
Bi‐ and Trinuclear Copper(II) Complexes with a Bridging Pyrazole/Oxime Ligand: Structures and Magnetic Properties
No full textThe pyrazole-based asymmetric ligand 3-[(1E)-N-hydroxyethanimidoyl]-4-methyl-1H-pyrazole-5-carboxylic acid (L) is shown to serve as a versatile ligand in copper(II) coordination chemistry with both the pyrazole and the oxime groups as potential bridges upon deprotonation. Three complexes [Cu-2(L-2H)(2)(DMSO)(H2O)].H2O (1a), [Cu-2(L-2H)(2)(DMSO)(2)].H2O (1b) and [Cu-3(L-3H)(2)(Py)(5)] (2) have been isolated and their crystal structures determined by X-ray single crystal analysis. The former feature a bis(pyrazolato)-bridged dicopper core, whereas adjacent copper ions are spanned by a pyrazolate and an oximate in the latter complex. The presence of different species in solution depending on the pH has been demonstrated by EPR. Alterations in the protonation state are accompanied by changes in nuclearity., which cause pronounced changes in color, magnetic and EPR properties. Magnetic susceptibility measurements in the temperature range 1.8 - 300 K have revealed anti ferromagnetic exchange coupling between copper(II) ions both in the bi- and trinuclear complexes (J = -160 cm(-1) for 1 and -191cm(-1) for 2). The binuclear species [Cu-2(L-2H)(2)] is almost silent in X-band EPR at 77 K due to antiparallel alignment of the unpaired Cu-II electrons, while the EPR signatures of species at alkaline condition suggest a Cu-centered S = 1/2 state
