From particle cascade simulations (FLUKA) to finite element heat transfer and structural deformation analyses (ANSYS)
Particle cascade simulations coupled with subsequent finite element thermal and mechanical calculations are an advanced, extremely useful, and sometimes the only available and reliable tool for solving practical as well as general engineering problems related to design and construction of accelerator components. The FLUKA Monte Carlo code and the ANSYS Finite Element system are extensively used by us for this purpose. In this paper we discuss physical assumptions made when using these programmes, modes of their applications, and their interface. Successful application of their mainframe for estimating spatial distributions and time evolution of temperatures and stresses in the accelerator domain are shown as examples : for the LHC and SPS beam dumps, and for the neutrino target at the SPS
Solving the woolly mammoth conundrum: amino acid 15N-enrichment suggests a distinct forage or habitat
Understanding woolly mammoth ecology is key to understanding Pleistocene community dynamics and evaluating the roles of human hunting and climate change in late Quaternary megafaunal extinctions. Previous isotopic studies of mammothsâ diet and physiology have been hampered by the âmammoth conundrumâ: woolly mammoths have anomalously high collagen ÎŽ15N values, which are more similar to coeval carnivores than herbivores and which could imply a distinct diet and (or) habitat, or a physiological adaptation. We analyzed individual amino acids from collagen of adult woolly mammoths and coeval species and discovered greater â15N enrichment in source amino acids of woolly mammoths than in most other herbivores or carnivores. Woolly mammoths consumed an isotopically distinct food source, reflective of extreme aridity, dung fertilization and (or) plant selection. This dietary signal suggests that woolly mammoths occupied a distinct habitat or forage niche relative to other Pleistocene herbivores
Surface EMG decomposition using a novel approach for blind source separation
We introduce a new method to perform a blind deconvolution of the surface electromyogram (EMG) signals generated by isometric muscle contractions. The method extracts the information from the raw EMG signals detected only on the skin surface, enabling longtime noninvasive monitoring of the electromuscular properties. Its preliminary results show that surface EMG signals can be used to determine the number of active motor units, the motor unit firing rate and the shape of the average action potential in each motor unit

GEOPOLITICS AND GEOPOETICS IN STANISĆAW KOLBUSZEWSKIâS BALTIC ESSAYS
The paper discusses Stanislaw Kolbuszewskiâs essays devoted to the capitals of the Baltic states (W stolicach paĆstw baĆtyckich, PoznaĆ 1939; (In the Capitals of the Baltic States).) the author visited in the 1930s. Kolbuszewskiâs aim was to familiarize the Polish reader with modern Lithuania, Latvia, and Estonia as seen through the eyes of a (friendly) stranger. His book clearly transcends the conventional limits of its genre (travel writing, journalism, reportage). The three capitals function there as extended conceptual metaphors of the Baltic states, their history, architecture, urban layout, and local color being viewed by the Polish âtouristâ as symbolic manifestations of their inhabitantsâ national mentality. The paper focuses on the geopolitical and geopoetic ideas implicit in Kolbuszewskiâs account, exploring the connections between âimaginedâ geographical space and the nationâs collective memory. Curiously enough, though a Polish nationalist at heart, Kolbuszewski does not make any territorial claims on what was once âPolish Livoniaâ. Instead, he enthusiastically endorses Baltic nationalisms, dismissing the German and Russian cultural contributions as hostile foreign intrusions. The tropes of ethnic âpurityâ and folk cultures viewed as pillars of national identity, recurrent in Kolbuszewskiâs Baltic essays, bring to mind the anti-German propaganda employed by Polish National Democrats after WW1 and Polish communists after WW2 in their attempt to justify Polandâs annexation of German Silesia, Pomerania, and Masuria, symbolically redefined in the Polish political discourse as the so-called Regained Territories. The connection between Kolbuszewskiâs Baltic essays and his affinities with the Regained Territories narrative, as developed by Polish Western Thought and the Piast historiography, is our focus in this article
GEOPOLITICS AND GEOPOETICS IN STANISĆAW KOLBUSZEWSKIâS BALTIC ESSAYS
The paper discusses Stanislaw Kolbuszewskiâs essays devoted to the capitals of the Baltic States (W stolicach paĆstw baĆtyckich, PoznaĆ 1939) that the author visited in the 1930s. Kolbuszewskiâs aim was to familiarize the Polish reader with modern Lithuania, Latvia, and Estonia as seen through the eyes of a (friendly) stranger. The authors of the paper focus on the geopolitical and geopoetic ideas implicit in Kolbuszewskiâs account of his travels to Riga, Tallinn and Kaunas, searching for the connections between geographic space, culture, civilization, history, traditions and the collective memory. What seems particularly intriguing about Kolbuszewskiâs report is the dynamic interplay between the personal perspective of âthe Otherâ and the numerous historical affinities between Poland and the Baltic states modifying that âotherness.
Avaliação socioeconĂŽmica e anĂĄlise do relato verbal de pais de crianças portadores de sĂndromes genĂ©ticas na regiĂŁo da trĂplice fronteira
Anais do V Encontro de Iniciação CientĂfica e I Encontro Anual de Iniciação ao Desenvolvimento TecnolĂłgico e Inovação â EICTI 2016 - 05 e 07 de outubro de 2016 â SessĂŁo CiĂȘncias BiolĂłgicasA genĂ©tica clĂnica vem adquirindo uma importĂąncia cada vez maior, que pode ser
justificada pelo aumento da incidĂȘncia das doenças genĂ©ticas em vĂĄrios paĂses, sendo que na
maioria dos casos, as pessoas desconhecem suas condiçÔes médicas e não são diagnosticadas
corretamente para tal. Diante desse quadro o aconselhamento genético se apresenta com
fundamental, jĂĄ que tem como princĂpio investigar adequadamente problemas genĂ©ticos,
proporcionando melhor entendimento aos portadores, para que esses lidem de melhor forma
com as doenças genéticas.
Além disso, a um grande déficit na literatura sobre correlaçÔes entre o perfil
comportamental e doenças genéticas. Dessa forma, esse trabalho teve como relevùncia
diminuir a escassez de estudos no Brasil e na América Latina, em especial na região da
trĂplice fronteira, tendo como objetivo avaliar o perfil com sĂndromes genĂ©ticas, a partir do
relato dos pais
