Change in local regulation of hemopoiesis under the chronic exposure to ionizing radiation
Get PDFResults of annual examinations of peripheral blood and single examinations of bone marrow after 11, 14, 15, and 22 years of the chronic exposure to ionizing radiation in total doses of 24.25, 103.96, 111.84, and 74.09 mSv, respectively, are presented along with the results on the morphology of microvasculature vessels in skin tissue samples of two men and two women working at a nuclear reactor. Changes in the content of hemoglobin, total number of leucocytes, population of erythrocytes, neutrophils, reticulocytes, and in the composition of maturating and mature myeloid and erythroid cells accompanied by an increase составе in the number of cells of the lymphoid and monocytic pool as the intensity of inflammatory changes in microvasculature vessels increases from productive panvasculitis to panvasculitis with sclerosis of vessel wall were noticed. The presented actual material indicates that damages in the blood system can be connected with the intensity of pathological changes in microvasculature vessels, which represent one of the local components of hemopoiesis-inducing microenvironment responsible for hemopoiesis regulation
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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Изменения микроциркуляторного русла у участников ликвидации последствий аварии на Чернобыльской АЭС в отдаленные сроки
Get PDFMechanisms of microcirculatory vascular bed injuries in Chernobyl NPS accident liquidators are considered in the paper. Liquidators who participated in reconstructive works on the territory of nuclear power-station were influenced by non-considered weakly penetrating β-radiation and by registered hard γ-radiation in small doses. Chronic inflammatory process in skin vessels (chronic panangiitis) which is considered to be caused by soft β-radiation predetermines peculiarities of blood vessels’ recovery which were damaged by external γ-radiation.В статье рассматриваются механизмы поражения сосудов микроциркуляторного русла у участников ликвидации последствий аварии на Чернобыльской АЭС. Ликвидаторы, участвовавшие в восстановительных работах на территории Чернобыльской АЭС, подверглись воздействию неучтенного слабопроникающего β-излучения и зарегистрированного жесткого γ-излучения в малых дозах. Предполагается, что хронический воспалительный процесс в сосудах кожи – хронический панангиит, вызванный воздействием β-излучения, предопределяет особенности репарации кровеносных сосудов, поврежденных вследствие внешнего γ-излучения
Изменение локальной регуляции кроветворения при хроническом воздействии ионизирующего излучения
Get PDFResults of annual examinations of peripheral blood and single examinations of bone marrow after 11, 14, 15, and 22 years of the chronic exposure to ionizing radiation in total doses of 24.25, 103.96, 111.84, and 74.09 mSv, respectively, are presented along with the results on the morphology of microvasculature vessels in skin tissue samples of two men and two women working at a nuclear reactor. Changes in the content of hemoglobin, total number of leucocytes, population of erythrocytes, neutrophils, reticulocytes, and in the composition of maturating and mature myeloid and erythroid cells accompanied by an increase составе in the number of cells of the lymphoid and monocytic pool as the intensity of inflammatory changes in microvasculature vessels increases from productive panvasculitis to panvasculitis with sclerosis of vessel wall were noticed. The presented actual material indicates that damages in the blood system can be connected with the intensity of pathological changes in microvasculature vessels, which represent one of the local components of hemopoiesis-inducing microenvironment responsible for hemopoiesis regulation.Приведены результаты исследований периферической крови, проводимых ежегодно, костного мозга, исследованного однократно в конце 11, 14, 15, 22 лет хронического воздействия ионизирующего излучения в суммарных дозах 24,25; 103,96; 111,84; 74,09 мЗв соответственно, и морфологии сосудов микроциркуляторного русла в биоптатах собственно кожи у двух мужчин и двух женщин - работников ядерного реактора. Отмечены изменения в содержании гемоглобина, общего количества лейкоцитов, численности эритроцитов, нейтрофилов, ретикулоцитов, в составе созревающих и зрелых клеток миелоидного, эритроидного ряда, сопровождающиеся увеличением численности клеток лимфоидного и моноцитарного пула, по мере нарастания выраженности воспалительных изменений в сосудах микроциркуляторного русла от продуктивного панваскулита до панваскулита со склерозом сосудистой стенки. Представленный фактический материал свидетельствует, что нарушения в системе крови могут быть связаны с выраженностью патологических изменений сосудов микроциркуляции - одного из локальных компонентов гемопоэзиндуцирующего микроокружения, ответственного за регуляцию кроветворения
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
