Polyakov log coarse garnet occurrence in the South Urals
No full textOntogenic modeling of the origin of coarse garnet of the Polyakov log occurrence (South Urals) in a fine-grained schist sequence allowed the authors to conclude on its metasomatic growth with the replacement of chlorite aggregates. Muscovite, ilmenite, epidote, quartz and apatite remain preserved in the primary schist orientation of individuals. Accessory andesine, cobaltite, pentlandite, pyrrhotite and zircon crystallized together with garnet. The formation of coarse garnet crystals is probably related to fluctuations of supersaturation relative to garnet in areas of schists with abundant chlorite. This allows us to expect the presence of coarse garnet areas in adjacent parts of the schist sequence

Today's lifestyles, tomorrow's cancers: Trends in lifestyle risk factors for cancer in low- and middle-income countries
No full textBackground: The global burden of cancer is projected to increase from 13.3 to 21.4 million incident cases between 2010 and 2030 due to demographic changes alone, dominated by a growing burden in low- and middle-income countries (LMICs). Lifestyle risk factors for cancer are also changing in these countries and may further influence this burden.Design: We consider examples of changes already occurring in population-level distributions of tobacco and alcohol consumption, body weight, and reproductive lives of women to gauge the magnitude of their projected impact on cancer incidence in future decades.Results: Trends in lifestyle factors vary greatly between settings and by sex. Some common trends point to considerable increases in cancers of the (i) lung in men due to tobacco smoking; (ii) upper aerodigestive tract (UADT) due to increasing tobacco and alcohol consumption, worse in men; (iii) colon from increasing body mass index, and alcohol and tobacco consumption; and (iv) in women, breast due particularly to consistent international trends of younger age at menarche, smaller family size, and, at postmenopausal ages, increasing body weight.Conclusions: In many LMICs, the future cancer burden will be worsened by changing lifestyles. Affected common cancer sites likely to experience the largest increases are lung, colon, UADT, and breast. © The Author 2011.

Expanding the Applicability of the Competitive Modes Conjecture
No full textThe Competitive Modes Conjecture is a relatively new approach in the field of Dynamical Systems, aiming to understand chaos in strange attractors using Resonance Theory. Up till now, the Conjecture has only been used to study multipolynomial systems because of their simplicity. As such, the study of non-multipolynomial systems is sparse, filled with ambiguity, and lacks mathematical structure. This paper strives to rectify this dilemma, providing the mathematical background needed to rigorously apply the Competitive Modes Conjecture to a certain set of non-multipolynomial systems. Afterwards, we provide an example of this new theory in the non-multipolynomial Wimol-Banlue Attractor, something that up to this point has not been possible as far as the authors know.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Numerical Analysi
Transições de fase na matéria de quarks magnetizada com repulsão vetorial
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas, Programa de Pós-Graduação em Física, Florianópolis, 2015.Neste trabalho investigamos as transições de fase na matéria de quarks magnetizada usando o modelo de NJL com dois sabores na presença de acoplamento vetorial repulsivo (GV). Verificamos que a contribuição vetorial produz o encolhimento da linha de transição de primeira ordem e pode favorecer o mecanismo de back-bending no regime de acoplamento forte. Este fato permite conciliar alguns resultados da rede com as previsões teóricas sobre a existência de um ponto crítico no diagrama de fases da QCD. Analisamos como a ação de um campo magnético (B) intenso na matéria de quarks tende a fortalecer a região de primeira ordem e que também determina um padrão oscilatório na densidade. Concluímos que os efeitos opostos do acoplamento vetorial e do campo magnético na restauração da simetria quiral levam a um desdobramento de múltiplas fases magnetizadas. A ação combinada de B e GV pode originar linhas de coexistência no diagrama de fases que apresentam um comportamento exótico similar ao observado para a transição sólido-líquido da água. Mostramos como a influência da repulsão vetorial deve estabilizar fases magnéticas de densidade intermediária e que certas combinações dos parâmetros B e GV determinam pontos triplos no diagrama de fases. Exploramos as propriedades magnéticas anisotrópicas sobre os quarks e como a contribuição vetorial deve afetar a magnetização induzida determinando um comportamento diamagnético para o sistema.Abstract : In this work we investigate the phase diagram of dense magnetizedquark matter in the framework of the two-flavor Nambu-Jona-Lasiniomodel when a repulsive vector coupling (GV ) is present. We verifythat the vector contribution could shrink the first order transition lineand can support the back-bending mechanism under a strong couplingregime. This result allows one to conciliate some lattice results withtheoretical predictions about the existence of a critical point in theQCD phase diagram. Our analysis shows how an intense magnetic field(B) acts in the quark matter, strengthening the coexistence region inthe phase diagram and setting an oscillatory pattern in density values.The opposite effect of the vector coupling and magnetic field in thechiral symmetry restoration leads to a splitting of multiple magneticphases. The combined action of B and GV gives rise to coexistencelines which can render an exotic behavior resembling the solid-liquidtransition observed in the water phase diagram. We show how thevector repulsion stabilizes the intermediary magnetic phases and thatcertain B and GV parametric combinations can cause a triple point toappear in the phase diagram. We also study the anisotropic propertiesof magnetized quark matter and how the vector-like contribution affectsthe induced magnetization leading to a diamagnetic behavior

Model improvements to simulate charging in SEM
No full textCharging of insulators is a complex phenomenon to simulate since the accuracy of the simulations is very sensitive to the interaction of electrons with matter and electric fields. In this study, we report model improvements for a previously developed Monte-Carlo simulator to more accurately simulate samples that charge. The improvements include both modelling of low energy electron scattering and charging of insulators. The new first-principle scattering models provide a more realistic charge distribution cloud in the material, and a better match between non-charging simulations and experimental results. Improvements on charging models mainly focus on redistribution of the charge carriers in the material with an induced conductivity (EBIC) and a breakdown model, leading to a smoother distribution of the charges. Combined with a more accurate tracing of low energy electrons in the electric field, we managed to reproduce the dynamically changing charging contrast due to an induced positive surface potential.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Charged Particle Optic
