No full textHeteromagnetic Microelectronics: Microsystems of Active Type, by Alexander A. Ignatiev of Saratov State University and Alexander V. Lyashenko of JSC Research Institute Tantal in Russia, offers a very detailed and specialized account of the author's research and development of heteromagnetic materials and devices. The book is based on original material from the author's programs of designing heteromagnetic microsystems. Polyvalent, multiple parameter magneto-semiconductor microsystems are described and the book reports on extensive experimental and theoretical results of research in a range of frequencies up to 1000 GHz. For the first time the direction of satisfying criteria, and burst technologies, which can make a subject of discovery, are discussed in great detail. This book is intended for post-graduate students and researchers specializing in the design and application of heteromagnetic materials and devices. Alexander A. Ignatiev is author of Magnetoelectronics of Microwaves and Extremely High Frequencies in Ferrite Films (Springer, 2009)

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Summary
The article deals with the results of the trials devoted to pilocarpine-induced spontaneous seizure activity pathophysiologic mechanisms investigation. With this aim the main factors determining spontaneous seizure onset were studied as well as hippocampus and frontal cortex pathogenetic role was investigated in conditions pilocarpine-induced chronic epileptogenesis. Status epilepticus development and its duration were shown to be the main factors determining pilocarpine-induced spontaneous seizures. Hippocampal hyperactivation was found to precede the spontaneous seizures formation that afterwards followed by the brain frontal cortex f the electrical activity strengthening. These brain structures electrical activity hyperactivation occurs due to a- and d-rhythms.
Key words: pilocarpine, spontaneous seizures, the hippocampus, cerebral cortex, the power of the electrical activity, pathophysiologic mechanisms.
Резюме
В роботі наведені результати досліджень, присвячених з'ясуванню патофізіологічних механізмів спонтанної судомної активності, індукованої введенням пілокарпіну. З цією метою вивчали основні чинники, що визначають розвиток спонтанних судом, а також з'ясовували патогенетичну роль гіпокампу і фронтальної кори в умовах пілокарпін-викликаного хронічного епілептогенезу. Показано, що розвиток епілептичного статусу, а також його тривалість детермінують формування спонтанних пілокарпін-викликаних судомних реакцій. Визначено, що формуванню спонтанних судом передує гіперактивація нейронів гіпокампу, слід за чим посилюється електрична активність фронтальної кори мозку. Посилення електричної активності зазначених утворень мозку відбувається за рахунок a- та d-діапазонів.
Ключові слова: пілокарпін, спонтанні судоми, гіпокамп, кора мозку, потужність електричної активності, патофізіологічні механізми.

ИЗУЧЕНИЕ МОЩНОСТИ ЭЛЕКТРИЧЕСКОЙ АКТИВНОСТИ СТРУКТУР МОЗГА В УСЛОВИЯХ ПИЛОКАРПИН-ИНДУЦИРОВАННОЙ СПОНТАННОЙ СУДОРОЖНОЙ АКТИВНОСТИ. В работе приведены результаты исследований, посвященных выяснению патофизиологических механизмов спонтанной судорожной активности, индуцированной введением пилокарпина. С этой целью изучали основные факторы, определяющие развитие спонтанных судорог, а также выясняли патогенетическую роль гиппокампа и фронтальной коры в условиях пилокарпин-вызванного хронического эпилептогенеза. Показано, что развитие эпилептического статуса, а также его продолжительность детерминируют формирование спонтанных пилокарпин-вызванных судорожный реакций. Выяснено, что формированию спонтанных судорог предшествует гиперактивация нейронов гиппокампа, за которой потом следует усиление электрической активности фронтальной коры мозга. Усиление электрической активности отмеченных структур мозга происходит за счет a- и d-диапазонов.

Variations on the Author
No full text“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
Dioxomolybdenum(VI) and dioxotungsten(VI) complexes supported by an amido ligand
No full textStepwise addition of one equivalent of n-butyllithium and trimethylsilyl chloride to 2-tert-butylmercaptoaniline affords the new ligand 1-(Me(3)SiNH)-2-(t- BuS)C(6)H(4)(LH), that reacts with one equivalent of butyllithium to its lithium salt LLi. Dioxodichloromolybdenum [MoO(2)Cl(2)] and dioxodichlorotungsten dimethoxyethane [WO(2)Cl(2)(dme)] react in tetrahydrofuran solution at low temperature with two equivalents LLi to monomeric dioxomolybdenum(VI) [MoO(2)L(2)] (1) and dioxotungsten(VI) complex [WO(2)L(2)] (2) employing two bidentate amido thioether ligands. The crystallographic determination of the molecular structures of 1 and 2 show evidence for M center dot center dot center dot S contacts. The reaction of [ MoO2Cl2] with LLi in tetrahydrofuran solution at room temperature leads next to 1 to two compounds where silyl group migration from nitrogen to oxygen atoms occurs forming [Mo(= NL')(2)(OSiMe)(2)] (3) and [Mo(= NL')(2)(OSiMe(3))L] (4, L' = N-2-t-BuSC(6)H(4)) as determined by NMR spectroscopy. Compound 4 was isolated in low yield and its molecular structure determined by X-ray crystallography. Higher yields of a bisimido complex can be obtained by the direct reaction of one equivalent of LLi with [Mo(NAr)(2)Cl(2)(dme)] (Ar = 2,6-Me(2)C(6)H(4)) forming [Mo(NAr)(2)LCl] (5)
