Aqui jaz uma morte: atitudes fúnebres na trajetória da empresa funerária da família Haas de Blumenau
Tese (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

The Behaviour of Haloacetic Acids in Distribution Zones in Scotland
HAAs are the second most prevalent class of DBPs after THMs in chlorinated drinking water and are of concern due to their potential human health risk. Their concentrations in drinking water are regulated by the US Environmental Protection Agency (US EPA) and other regulatory agencies and are currently under consideration by the European Union to be regulated at 80μg/L. However their monitoring in the distribution system is complicated because several parameters influence their formation and speciation. In addition the kinetics of HAAs and their formation and stability remain largely unidentified. The HAAs are not as chemically or biologically stable as THMs in aquatic systems and their stability may impact their measurement.
The levels of HAAs within a distribution system may vary seasonally and spatially. Many studies have shown that their concentration in a distribution system can rise as well as fall. The levels of HAAs in the distribution system could be increased in the presence of residual chlorine or due to the decomposition from other DBPs and be decreased by biodegradation or hydrolysis and abiotic degradation. However biodegradation is likely the major loss process occurring in drinking water distribution systems.
This study provides an interesting picture of HAAs levels in distribution water in Scotland. A statistical analysis has been carried out using measurements of HAAs concentrations and other water quality parameters from 298 Scottish water distribution zones in to investigate the relative occurrence and speciation of HAAs, and determine their behaviour in water distribution systems, monitoring differences between zones. This study also allowed evaluation of the impact of seasons on HAAs concentrations and speciation in Scotland’s distribution zones.
The results obtained show that the median concentrations of HAA5 is 11.5μg/L. The average HAA5 in distribution systems were about 50% lower than total trihalomethanes (THMs). In 0.7% of the zones under study, the average HAA5 concentration exceeds 60μg/L. These zones are supplied by small WTWs (<3,300 people) and are using chlorination.
HAAs concentrations varied according to their water source and the disinfection strategy used. Low HAA5 levels (the median was <5.3 μg/L) were observed in the groundwater systems and higher levels were observed in the surface water systems (the median was 12.4 μg/L). The chloraminated waters have lower HAA5 and THMs levels compared to chlorinated waters, but the difference is not that pronounced. Generally chlorinated HAAs dominated in the waters of the distribution under study. The dominant species were trichloroacetic acid (TCAA) and dichloroacetic acid (DCAA). DCAA and TCAA were present at almost in equal levels in chlorinated waters but DCAA was the dominant group detected when using chloramination. Furthermore seasonal variations of the concentrations of different HAAs species were observed. The concentrations of HAA5 were higher in summer and autumn and lower in winter and spring but the difference was not statistically significant. THMs has a similar seasonal pattern but with a more pronounced variation than HAAs. The median data show almost no seasonal variation for dichlorinated HAAs. However the seasonal variation of TCAA is more pronounced and higher concentrations were detected during summer and autumn.When the data sets from all distribution zones were combined there was a strong correlation between total THMs and HAA5, total THMs and TCAA and HAA5 and total organic carbon (TOC).
The spatial variability of HAAs and THMs concentrations in two distribution zones using different disinfection strategies (chloramination and chlorination) was also studied. There has previously been no full scale study in the UK with the attempt to link the behaviour to distribution factors such as microbial water quality or distribution mains material.
In both systems THMs generally presented stable and increasing concentration profiles along the system, whereas HAAs increased and decreased, a phenomenon probably related to biodegradation. There is also evidence that abiotic reduction of HAAs is possible in the iron pipes for the chlorinated distribution system.
Using flow cytometry we observed generally higher levels of total and intact cells in the chloraminated distribution zone. Thus large numbers of dead cells can contribute to HAAs formation
Biochemical analysis of the native TRAIL death-inducing signaling complex
The extrinsic apoptosis pathway is activated when certain members of the tumor necrosis factor (TNF) receptor superfamily (TNFRSF) are oligomerized by their cognate ligands that are members of the TNF superfamily (TNFSF). The apoptosis-inducing capacity of a member of the TNFRSF relies on the presence of a death domain (DD) in the intracellular portion of the receptor protein. Such receptors are also referred to as death receptors. Binding of a TNFSF ligand to a TNFRSF receptor that is expressed on the surface of a cell results in the formation of a receptor proximal protein complex. This protein complex is the platform for further signaling events within the cell. In case of death receptors like TNF-related apoptosis-inducing ligand receptor 1 (TRAIL-R1/DR4), TRAIL-R2 (KILLER/APO-2/DR5/TRICK), CD95 (Fas, APO-1), or TNF receptor 1 (TNF-R1), this complex is termed death-inducing signaling complex (DISC). The compositions of the various DISCs have been intensively studied in the last 12 years. For the CD95 and the TRAIL-R1/R2 DISCs, it is now clear that the adaptor protein Fas-associated DD protein (FADD) forms part of these complexes and is necessary for recruitment of the proapoptotic signaling molecules caspase-8 and caspase-10. Recruitment of these proteases allows for their activation at the DISC and subsequent induction of apoptosis. The caspase-8 homologous cellular FLICE-like inhibitory protein (cFLIP) can also be recruited to the DISC. cFLIP acts as an anti-apoptotic regulator by interfering with activation of caspases 8 and 10 at the DISC. Interestingly, treatment of TRAIL-resistant tumor cells with conventional chemotherapeutic drugs or with proteasome inhibitors renders these cells sensitive for TRAIL-induced apoptosis. By applying the methodology of the biochemical analysis of the TRAIL DISC described here, we were able to show that this sensitization is mainly due to changes in the biochemical composition of the DISC as the apoptosis-initiating protein complex of the extrinsic pathway
