Aqui jaz uma morte: atitudes fúnebres na trajetória da empresa funerária da família Haas de Blumenau
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2013.Desde os primeiros anos do século XX, a empresa da família Haas de Blumenau (Santa Catarina, Brasil) dedica-se ao mercado funerário. A pequena oficina, fundada por Mathias e seu pai, estabeleceu-se com a fabricação de túmulos e a arte dos marmoristas, com destaque para o próprio Mathias que esculpiu na pedra, túmulos e ornamentos funerários. A administração da empresa, sempre a cargo de membros da Haas, depois de algumas décadas de dedicação à arquitetura funerária e também civil, concentrou seus esforços na gerência de uma agência funerária. Com a funerária, a empresa ofereceu aos seus clientes uma série de serviços voltados ao cuidado do corpo e por último, entrou no segmento de vendas de planos funerários. Desde a sua fundação, a empresa enfrentou mudanças e teve que administrar momentos de transição e de adequação de seus produtos e investimentos para conciliar mudanças nos ritos e a entrada de novidades no mercado funerário. A trajetória da família Haas possibilitou as reflexões desta tese que buscou pensar sobre as atitudes fúnebres e a morte, em diferentes momentos, por meio de sua empresa. Contando com um acervo documental formado por imagens, escritos pessoais, partes de construções tumulares, blogs, notas fiscais, documentos administrativos, catálogos de modelos tumulares e depoimentos, foram percebidas mudanças no tratamento do corpo morto e no seu destino final. <br

Significant Improvement in Energy Efficiency in Manufacturing at Rohm and Haas��� Kankakee, Illinois, Plant
No full textSignificant improvement in energy efficiency was achieved at Rohm and Haas��� Kankakee, Illinois facility last year through the combined efforts of all plant personnel. In total, a 24% reduction in energy requirements per pound of product produced was reached compared to 2004. That amounts to $270,000 in savings in 2005 with 1000 fewer tons of CO2 emitted to the environment
The de Haas van Alphen effect near a quantum critical end point in Sr₃Ru₂O₇
No full textHighly correlated electron materials are systems in which many new states of matter can emerge. A particular situation which favours the formation of exotic phases of the electron liquid in complex materials is that where a quantum critical point (QCP) is present in the phase diagram. Neighbouring regions in parameter space reveal unusual physical properties, described as non-Fermi liquid behaviour.
One of the important problems in quantum criticality is to find out how the Fermi surface (FS) of a material evolves near a QCP. The traditional method for studying the FS of materials is the de Haas van Alphen effect (dHvA). A quantum critical end point (QCEP) has been reported in the highly correlated metal Sr₃Ru₂O₇, which is tuned using a magnetic field high enough to perform the dHvA experiment. It moreover features a new emergent phase in the vicinity of the QCEP, a nematic type of electron ordering.
The subject of this thesis is the study of the FS of Sr₃Ru₂O₇ using the dHvA effect. Three aspects were explored. The first was the determination of the FS at fields both above and below that where the QCEP arises. The second was the search for quantum oscillations inside the nematic phase. The third was a reinvestigation of the behaviour of the quasiparticle effective masses near the FS.
In collaboration with angle resolved photoemission spectroscopy experimentalists, a complete robust model for the FS of Sr₃Ru₂O₇ at zero fields was determined. Moreover, the new measurements of the quasiparticle masses revealed that no mass enhancements exist anywhere around the QCEP, in contradiction with previous specific heat data and measurements of the A coefficient of the power law of the resistivity. Finally, we report dHvA oscillations inside the nematic phase, and the temperature dependence of their amplitude suggests strongly that the carriers consist of Landau quasiparticles

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling
No full textCD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation. Naive human T cells triggered by antigen-presenting cells expressing a membrane-bound form of CD95 ligand (CD95L) or stimulated by anti-CD3 and -CD28 antibodies in the presence of recombinant CD95L had reduced activation and proliferation, whereas preactivated, CD95-sensitive T cells underwent apoptosis. Triggering of CD95 during T cell priming interfered with proximal T cell receptor signaling by inhibiting the recruitment of ζ-chain–associated protein of 70 kD, phospholipase-γ, and protein kinase C-θ into lipid rafts, thereby preventing their mutual tyrosine protein phosphorylation. Subsequently, Ca2+ mobilization and nuclear translocation of transcription factors NFAT, AP1, and NF-κB were strongly reduced, leading to impaired cytokine secretion. CD95-mediated inhibition of proliferation in naive T cells could not be reverted by the addition of exogenous interleukin-2 and T cells primed by CD95 co-stimulation remained partially unresponsive upon secondary T cell stimulation. HIV infection induced CD95L expression in primary human antigeen-presenting cells, and thereby suppressed T cell activation, suggesting that CD95/CD95L-mediated silencing of T cell activation represents a novel mechanism of immune evasion
Automated recognition of 3D CAD objects in site laser scans for project 3D status visualization and performance control
No full textThis paper presents a new approach that allows automated recognition of three-dimensional (3D) computer-aided design (CAD) objects from 3D site laser scans. This approach provides a robust and efficient means to recognize objects in a scene by integrating planning technologies, such as multidimensional CAD modeling, and field technologies, such as 3D laser scanning. Using such an approach, it would be possible to visualize the 3D status of a project and automate some tasks related to project control. These tasks include 3D progress tracking, productivity tracking, and construction dimensional quality assessment and quality control. This paper provides an overview of the developed approach and demonstrates its performance in object recognition and project 3D status visualization, with data collected from a construction job site.</p
Mehr Leben als Tod in Rom. Josef Winklers römische Novelle «Natura morta»
No full textThe essay’s introduction examines the importance of Italy for Josef Winkler and puts the novella «Natura morta» in context with his oeuvre. The subsequent analysis of the text highlights the technique used by the author, which shows similarities with the process of film shooting. The narrator’s eye follows the main character like a movie camera and is focused on numerous details as if it were zooming on them. In this process, while advancing the novella’s plot, the author paints a colorful portrait of Rome, bringing the city to
