This thesis examines major publications produced between 1891-2015 that portray the trial of Florence Maybrick. Inspired by Paul Davis’ Lives and Times of Ebenezer Scrooge, it considers the various iterations of Florence’s story as “protean fantasies,” in which the narrative changed to reflect the realities of the time in which it was (re)written. It tracks shifting patterns of emphasis and authors’ rigid conformity to associated sets of discursive strategies to argue that this body of literature can be divided into three distinct epochs. The 1891-1912 era was characterized by authors’ instrumentalization of sympathy on Florence’s behalf in response to contemporary concerns about the administration of criminal justice in England. From 1923 until 1964, this “Victorian tragedy” was re-structured according to the tropes of detective fiction and non-fiction crime writing in a cultural atmosphere increasingly preoccupied with postmodernism, “the psychological,” and shifting gender relations. The concept of the “permissive society” and emergence of “new social history” following the late 1960s and early 70s produced a revised version of the story that accentuated aspects of the case that were illustrative of the structures of Victorian society. As such, this thesis is a metahistorical examination of how authors’ approaches to the question of whether or not Florence poisoned her husband in 1889 have been shaped by contemporary mentalités. / Graduate

Methanol poisoning usually comes to the forefront of both professional and general public interest at times, when there is a larger outbreak, outside of these periods these cases appear sporadically. They occur in the whole world, in the developed countries as well as in the developing ones, independently of any restriction on the consumption of alcoholic beverages by the state. In Czech society this topic came to surface especially in 2012, when as a result of methanol intoxication the minimum of 50 people died and many more suffer permanent damage. The trickiness of methanol lies in the fact, that it is not possible to recognize it from ethanol in an alcoholic drink or in any other mixture. Most often it penetrates the organism by way of ingestion; it can also be absorbed through the skin or by inhalation. Methanol itself is not toxic; its metabolites (formaldehyde and formic acid) however present a problem. Typical symptoms include visual disturbances, deepening metabolic acidosis with an increased anion gap and damage to basal ganglia, particularly the putamen. The intoxication is further accompanied by a range of nonspecific symptoms such as stomach pain, nausea, vomiting, impairment of consciousness and cognitive functions. The gravity of the intoxication depends on the amount of ingested methanol and on the mixing ratio with ethanol. Therapy consists of administering specific antidotes ethanol or fomepizole, modifying of the internal environment, continuous or intermittent hemodialysis, if necessary and allowed by the patient's condition and in supportive treatment for maintaining the stability of vital functions. Nursing care has an unreplaceable role in treatment of these patients. Nurses come to contact with these patients in every sector of healthcare, they take part in admission, stabilization and monitoring of vital functions, they tend to the invasions as well as to maximal psychic and physical comfort of the patient. They take part in rehabilitation and also help patients returning into normal life. This thesis deals with the properties of methanol, its production and toxicity, it explores methanol intoxication, its symptoms and sequelae, diagnostics and therapy as well as nursing care in detail. It follows the role of nurses of all the sectors of health care in managing all the stages of the intoxication with emphasis on selected nursing activities in the intensive, standard or aftercare. The thesis concludes with 4 documented case studies. The aim of this thesis was to process the information collected on this topic into a complex and current overview of knowledge on methanol poisoning and the possibilities of dealing with it all of the phases of the poisoning including the aftercare of the patients who were affected. A summary of procedures and variations thereof was acquired on the theoretical basis of Czech and foreign sources such as books, renowned periodicals in paper or electronic form and by means of web sites of professional societies. The sum of knowledge this thesis provides can serve for teaching needsor continuing education of healthcare workers concerning diagnostics, therapy and management of the sequelae of this intoxication with special emphasis on the possibilities of nurse´s intervention in any of the phases of it, or to provide base for further research in this area.

Dois surtos de intoxicação por selênio em suínos que ocorreram no estado do Paraná são descritos. Foram acometidos leitões em fase de creche, 16 de um lote de 100 com 27 dias de idade (surto 1) e 350 de 2285 com 22 dias de idade (surto2) apresentaram poliomielomalácia simétrica focal. Animais que sobreviveram aos surtos desenvolveram lesões de casco características de intoxicação crônica por selênio. Os sinais clínicos iniciaram após 6 dias e 30 horas da introdução da ração com alto teor de selênio nos surtos 1 e 2, respectivamente. O surgimento dos sinais foi abrupto, os animais começavam com andar cambaleante, evoluiam para paralisia dos membros pélvicos e progrediam para paralisia dos membros torácicos e tetraparesia. Os animais do surto 1 não tinham alterações de comportamento e mantinham estado de alerta e animais do surto 2 apresentaram quadros de depressão. Macroscopicamente, observaram-se focos circulares amarelados com áreas deprimidas mais escura, em alguns animais, restritas ao corno ventral da substância cinzenta (H medular) em intumescências cervical e lombar. Microscopicamente, essas áreas corresponderam à malácia da substância cinzenta, caracterizada por microcavitações, perda neuronal, cromatólise, neuronofagia, infiltrado de células Gitter, microgliose, astrócitos de Alzheimer tipo II e proliferação de células endoteliais evidenciadas na imuno-histoquímica (IHQ) para fator de von Willebrand. 9Continua) No segundo surto, dois animais apresentaram vacuolização difusa do citoplasma de neurônios. Em um animal, Astrócitos gemistocíticos foram observados. Na IHQ para Proteína Ácida Glial Fibrilar (GFAP), obteve-se marcação positiva na maioria dos animais e, na IHQ para Proteína S-100, obteve-se marcação em alguns casos. Além dessas alterações medulares, foram encontrados, em dois animais lesões de polioencefalomalácia em porções do tronco encefálico. Fragmentos de fígado de oito animais e ração de ambos os surtos foram encaminhados para dosagem de selênio. Em amostras de ração, detectou-se 3,38 ppm (surto 1) e 154 ppm (surto 2) e em amostras de fígado teve dosagens superiores a 3,34 ppm. No surto 2, foi realizada uma visita onde seis suínos foram eutanasiados para monitoramento de níveis hepáticos de selênio, sendo dois animais controles e quatro sobreviventes do surto. Quarenta e dois dias após a retirada da ração, os níveis de selênio foram inferiores ao controle e ao nível considerado em quadros de intoxicação (3 ppm). / Two outbreaks of selenium poisoning occurred in pigs in Cruzeiro do Iguaçu and Dois Vizinhos, both of the located in Paraná State. The affected pigs were in the post-weaning period, 16 out of 100 were 27 days of age (outbreak 1) and 350 out of 2285 were 22 days of age (outbreak 2). Affected animals showed signs of focal symmetrical poliomyelomalacia. Surviving pigs developed lesions in hoof, which are characteristic of chronic poisoning by selenium. Clinical signs were observed 6 days and 30 hours after the introduction of the feed with high selenium content in outbreaks 1 and 2, respectively. The appearance of the signs was abrupt, beginning with gait and progressing to paralysis of rear limbs and the forelimbs, or tetraparesis. Animals of outbreak 1 were alert and had no behaviors changes and animals of outbreak 2 showed depression. Macroscopically, in some animals there were yellow circular focus with dark areas, restricted to the ventral horn of the gray matter of spinal cord in cervical and lumbar intumescence. Microscopically, these areas corresponded to gray substance malacia characterized by microcavitation, neuronal loss, chromatolysis, Gitter cell infiltrate, neuronophagia, microgliosis, Alzheimer type II astrocytes and proliferation of endothelial cells, which were labeled by immunohistochemistry (IHC) for von Willebrand factor. In the second outbreak, two animals showed a diffuse cytoplasm vacuolization of the neurons. Gemistocytic astrocytes were observed in one animal. In most affected pigs, positive in test for glial fibrillary acid protein (GFAP) was observed, but only in some cases, there was positive anti-S-100 IHC. In addition these spinal cord changes were seen polioencephalomalacia in portions of the brainstem in two animals. Liver samples from eight animals and feed samples from both outbreaks were referred to determine selenium concentration. Selenium dosages in feed samples were 3.38 ppm (outbreak 1) and 154 ppm (outbreak 2) and in liver samples were above 3.34 ppm. Additions six animals were euthanized for monitoring hepatic levels of selenium, two were control animals and four were survivors of the second outbreak. 42 days after the withdrawal of the diet, selenium levels were lower than in internal control and the level seen in intoxication outbreaks (3 ppm).

The application of heterogeneous catalysts to industrial processes is a key factor in the synthesis of nearly all chemicals currently produced, however billions of pounds are lost every year due to unplanned reactor shutdowns and catalyst replacement as a result of catalytic deactivation processes. Poisoning of heterogeneous catalysts by sulfur compounds is a particularly prominent class of deactivation processes, affecting a wide range of catalytic materials and catalytic reactions, including the industrially-prominent Haber-Bosch process for the synthesis of ammonia and steam reforming of methane for the synthesis of hydrogen. However, while the effects of sulfur adsorption on catalytic behaviour are often unmistakably apparent, the fundamental interactions leading to these effects are not yet well understood. The work presented in this thesis uses a combination of models systems, novel and traditional characterization techniques, and methods of modifying catalyst geometric and electronic structure to approach the topic of sulfur poisoning from a fundamental perspective. Particular focus is placed on using selective decoration of active sites to develop a system of model hydrogenation reactions to relate changes in catalytic behaviour to changes in geometric and electronic structure. Application of these model reactions to investigate the sensitivities of palladium- and ruthenium-based catalytic systems to modification by sulfur shows contrasting effects for the two metals. While both systems exhibit similar geometric effects of modification, the palladium-based catalysts are far more sensitive than the ruthenium-based catalysts to modification of electronic structure. Additionally, controlled variation in particle size for the palladium-based catalysts demonstrates that catalytic behaviour is dominated by electronic structure for small nanoparticles and geometric structure for large nanoparticles. This leads small nanoparticles to show increased sensitivity to electronic modification effects resulting from sulfur adsorption. Ultimately, the research presented within this thesis provides a basis for the intelligent design of heterogeneous catalysts for improving tolerance for sulfur poisoning, and for utilizing the effects of sulfur modification to optimize catalytic activity and selectivity for the synthesis of fine chemicals.

The aim of this diploma thesis was to process an overview of previously known knowledge about acute mushroom poisonings. Thesis draws mainly from foreign literature. Provides basic information about mushrooms, their toxins and syndromes that cause. Beside the general information, one part of the thesis is devoted to the cases and studies from around the world. They describe individual clinical cases of mushroom poisoning or deal with their epidemiological situation mostly between the years 2001 - 2016. Obtained information is processed into overview tables. Thesis is particularly focused on the situation of macromycete poisonings in the Czech Republic and contains data from specialised facilities. The most intoxications occurs after ingestion of the edible fungi species. The most common intoxications by mushrooms containing toxins are after ingestion A. phalloides, A. pantherina and Psilocybe. The most frequent reported symptoms are gastrointestinal. According to the severity, mushroom poisonings are classified as less dangerous with onset of symptoms within 6 hours and life-threatening with the onset of symptoms after more than 6 hours. Mushroom poisonings should be considered in the differential diagnosis of gastrointestinal problems. Key words: macromycetes, mushroom poisonings, mushroom...

São descritas alterações macroscópicas e microscópicas em cascos de suínos em fase de creche, intoxicados por selênio. Os suínos apresentaram poliomielomalácia simétrica focal e lesões de casco, que inicialmente eram caracterizados por uma linha avermelhada na borda coronária que evoluiu nos suínos sobreviventes aos surtos, para desprendimento dos cascos. Os sinais clínicos iniciaram após seis dias (surto 1) e 30 horas (surto 2) da introdução da ração com alto teor de selênio. O surgimento dos sinais foi abrupto, caracterizado por andar cambaleante, com evolução para paralisia dos membros pélvicos e posteriormente tetraparesia. Durante a necropsia, nove suínos apresentaram lesões nos cascos, que variavam desde uma linha distal da borda coronária, nos casos iniciais, até uma linha enegrecida próxima a ponta dos cascos, nos suínos que sobreviveram. Microscopicamente, os achados variavam de leve desprendimento do epitélio laminar da derme, em casos iniciais, até ulceração do epitélio e infiltrado inflamatório acentuado, composto por neutrófilos íntegros e degenerados e alguns linfócitos, além de hemorragia, material vegetal aderido a superfície e miríades bacterianas, em casos avançados. Em amostras de ração, detectou-se 3,38 ppm (surto 1) e 154 ppm de selênio (surto 2) e em amostras de fígado foram encontradas dosagens superiores a 3,34 ppm (variando de 3,34 até 10 ppm). No surto 2, após 44 dias da retirada da ração, foi realizada eutanásia de seis suínos para monitoramento de níveis hepáticos de selênio (dois suínos controles e quatro sobreviventes ao surto) e todos apresentavam níveis normais de selênio no fígado e na musculatura esquelética. / Are described macroscopic and microscopic alterations on the hoofs of the pigs that was in postweaning period, poisoned by selenium. The pigs had focal symmetrical poliomielomalcia and lesions on the hoof, which were initially characterized by a reddish line on the coronary band that evolved in the survivors pigs of the outbreaks for detachment from hooves. Clinical signs were observed six days (outbreak 1) and 30 h (outbreak 2) after the introduction of feed with high concentrations of selenium. The appearance of the signs was suddenly, characterized by incoordination, progressing to paralysis of the hind limbs and later tetraparesis. During the necropsy, nine swine with lesions on the hoof, which varied from a line distal of coronary band, in early cases, until next blackened tip line on the hooves, in the pigs that survived. Microscopic findings varying from mild detachment of the laminar epithelium with the dermis, in early cases, with ulceration of the epithelium and a prominent inflammatory infiltrate, composed of intact and degenerate neutrophils and some lymphocytes, and hemorrhage, fibrous material adhered to the surface and bacterial myriads. In samples of feed, was detected 3.38 ppm (outbreak 1) and 154 ppm (outbreak 2), and liver samples were found at dosages higher than 3.34 ppm (range from 3.34 to 10 ppm). In outbreak 2, 44 days after the removal of the diet, was performed the euthanasia of six pigs to monitor levels of selenium liver (two controls and four surviving pigs to the outbreak) and all had normal levels of selenium in the liver and skeletal muscles.

The road transportation is a big source for the release of NOx emissions. NOx has been confirmed to cause negative affect on the air-quality especially in the urban areas, there are therefore regulations for allowed released amount from vehicles. The most adopted technology used for the reduction of these NOx emissions from the diesel exhaust gas is the ammonium selective catalytic reduction (NH3-SCR) using a Cu-zeolite as the catalyst in the system. The SCR catalyst can be deactivated through different mechanism, whereas poisoning by sulfur has been documented to be an important factor for the deactivation. The degree of deactivation of the catalyst has been suggested to vary depending on the catalytic material and which sulfur conditions the catalyst is exposed to, where SO3 has been indicated to cause more sever deactivation compared to SO2.  The aim of this project has been to investigate the deactivation mechanism of Cu-zeolites at different SOx conditions and evaluate potential regeneration mechanism. The project was carried out by evaluating the catalysts, Cu-BEA and Cu-SSZ-13, over different reactions that occurs in the SCR system, investigating the deactivation effect caused by SO2 poisoning and the regeneration potential. The project was then continued with the focus on the Cu-SSZ-13 catalyst investigating different SOx poisoning and regeneration conditions were investigated. In order to investigate the SO3 poisoning a generator using oxidation of SO2 to SO3 was successfully build during this project.  A kinetic model over the Cu-SSZ-13 NH3-SCR reactions was also built based on literature studies and the experimental data obtained. The results from the sulfur poisoning of Cu-BEA are based on the master thesis by Maria Arvanitidou. The fresh samples Cu-Beta and Cu-SSZ-13 exhibited similar activity, with the exception of the high formation of N2O observed over Cu-Beta under SCR conditions. The SO2 causes deactivation, especially at low temperatures. Cu-SSZ-13 exhibited more loss in activity but was able to recover more through the elevated SCR regeneration steps than the Cu-Beta. When SO2 exposure was performed together with NH3, larger deactivation was observed, likely due to ammonium sulfate species formed on the surface. The ammonium sulfate species were less thermally stable than copper sulfates, making it easier to recover the loss of activity in the Cu-SSZ-13. SO3 caused a much more sever deactivation of the SCR reactions than that of the SO2 poisoning and continued to show the lowest NOx removal activity after the regeneration process.  A difference in initial deactivation and recovery of activity between standard and fast SCR reactions was observed, indicating that the different mechanisms used are affected differently by the poisoning. The kinetic model for NH3-SCR over the Cu-SSZ-13 was successfully created when compared to the experimentally obtained data.

Elas são decorrentes da cadeia produtiva gerada pelo agronegócio e impactam sobre o ambiente e sobre as vidas animal e humana. Objetivo: Avaliar as notificações de intoxicações por agrotóxicos e a sua relação com o uso destes produtos em Mato Grosso, no período de 2007 a 2012. Métodos: Estudo realizado em duas etapas: na primeira foi realizada análise descritiva acerca das notificações de intoxicação por agrotóxicos registradas no SINAN, abrangendo as dezesseis Regiões de Saúde de Mato Grosso, no período de 2007 a 2012 e sua relação com a utilização deste produto no estado. Na segunda etapa foi realizado estudo analítico acerca destas intoxicações por agrotóxicos e realizada se análises descritiva, bivariada e regressão múltipla. Resultados: Etapa 1- Das 760 notificações analisadas, as regionais que apresentaram os maiores percentuais de casos estão inseridas na cadeia do agronegócio neste estado: Sinop (16%), Rondonópolis (13%), Barra do Garças (11%) e Tangará da Serra (9%). A maioria dos casos ocorreu de maneira acidental (39%) seguida pela tentativa de suicídio (29%). Etapa 2: Das 312 notificações resultantes da etapa 1, as maiores incidências de intoxicações ocorreram em indivíduos do sexo masculino (69,23%). A faixa etária com maiores frequências foi de 20 a 39 anos. 46,51% corresponderam á cor parda, e mais que metade dos casos (70%) possuía até o nível fundamental completo. O local da exposição foi o ambiente de trabalho (48%), intoxicação de forma acidental (38%). Nos meses de outubro a março foram verificadas as maiores ocorrências que coincidem com o período da safra agrícola. Em 66% dos casos houve atendimento hospitalar e em 2% dos intoxicados houve cura com sequelas. Foram encontradas associações entre três variáveis sobre as características de exposição aos agrotóxicos e a variável desfecho “se são decorrentes do trabalho”, que são: o ambiente de trabalho, agrotóxico de uso agrícola e exposição ambiental, sendo que todos apresentaram p= < 0,001. Considerações: Os resultados sinalizam para os impactos negativos do processo produtivo do agronegócio, indicando que os agrotóxicos que são utilizados intensivamente na produção agrícola, estão induzindo intoxicações agudas que coincidem com o período das safras agrícolas, sendo que as maiores incidências estão nas regionais maiores produtoras. Os dados sugerem temas específicos a serem incluídos nas capacitações destinadas aos profissionais de saúde: a) classificação de agente tóxico; b) nome comercial do agrotóxico; c) Princípio ativo e outros detalhes da vigilância de investigação das intoxicações exógenas do SINAN. Recomenda-se um estudo sobre a viabilidade de integração do Sistema de Informação de Agrotóxicos (SIA) à base de dados do SINAN, como meio de minimizar as falhas no preenchimento das variáveis referentes aos agrotóxicos. Faz-se necessário a implantação das ações da vigilância a saúde das populações expostas aos agrotóxicos em Mato Grosso. / The pesticide poisoning are characterized as public health problem worldwide and cause irreversible damage to the body of man, can evolve to death. They result in the production chain generated by agribusiness and impact on the environment and on human and animal lives. Objective: To evaluate reports of pesticide poisoning and its relation to the use of these products in Mato Grosso, in the period 2007 to 2012 Methods: Study conducted in two stages: first descriptive analysis was performed on notifications of pesticide poisoning recorded in SINAN, covering sixteen health regions of Mato Grosso, in the period from 2007 to 2012 and its relation to the use of this product in the state. In the second step was carried out analytical study on these pesticide poisoning and performed descriptive, bivariate and multiple regression analyzes. Results: Step 1 Of 760 complaints analyzed, the regional who had the highest percentages of cases are inserted in the agribusiness chain in this state: Sinop (16%), Rondonópolis (13%), Barra do Garças (11%) and Tangará da Serra (9%). Most cases occurred from accidental way (39%) followed by attempted suicide (29%). Step 2: Of the 312 notifications resulting from step 1, the highest incidences of poisoning occurred in males (69.23%). The age group with the highest frequency was 20-39 years. 46.51% were mixed race, and more than half the cases (70%) had completed elementary level up. The venue of the exhibition was the work environment (48%), accidental poisoning (38%). In the months from October to March the major events that coincide with the period of harvest were verified. In 66% of cases there was in hospital and 2% of cure was intoxicated with sequelae. Associations were found between three variables on the characteristics of pesticide exposure and the outcome variable "if they are from work", which are: the working environment, pesticide use in agriculture and environmental exposure, and all with p <0.001. Considerations: The results point to the negative impacts of the agribusiness production process, indicating that the pesticides that are used intensively in agricultural production, are inducing acute poisoning which coincide with the period of the harvest, with the highest incidences are higher in regional production . The data suggest specific to be included in training for professionals of health issues: a) classification of toxic agent; b) trade name of the pesticide; c) Active Ingredient and other details of the surveillance research of exogenous intoxications SINAN. A study on the feasibility of integrating the Pesticide Information System (CIS) database SINAN as a means of minimizing errors in the completion of the variables related to pesticides is recommended. It is necessary to implement the actions of the health surveillance of populations exposed to pesticides in Mato Grosso.

Além disso, estes produtos são comumente utilizados na aqüicultura para o controle de parasitoses. O teflubenzuron (TFB) é um inseticida registrado em alguns países da Europa para o controle de parasitas de peixes. Os possíveis efeitos tóxicos e risco ambiental do TFB podem ser avaliados inicialmente em condições de laboratório por meio de testes de toxicidade aguda com organismos-teste eleitos internacionalmente. Os objetivos deste trabalho foram avaliar a toxicidade aguda e o risco de intoxicação ambiental do uso agrícola e em aqüicultura do TFB, com base nos valores de CE50 e CL50 estimados em testes com Daphnia magna, Lemna minor e Poecilia reticulata, utilizados como organismos bioindicadores. Os testes de ecotoxicidade aguda foram realizados de acordo com normas nacionais e internacionais para estas espécies. A CE50-48h estimada para D. magna foi 0,00026 mg.L- 1, o que caracteriza este inseticida como altamente tóxico para esta espécie. Para L. minor, a CE50-7d estimada foi 1.176,16 mg.L-1, e para P. reticulata CL50-96h, 2.707,87 mg.L- 1, que classificam o TFB como praticamente não-tóxico para estas duas espécies. Devido à alta toxicidade do TFB para daphnídeos, mesmo em pequenas contaminações, pode causar desequilíbrio na cadeia alimentar aquática. Para minimizar o risco ambiental, o TFB pode ser utilizado de forma controlada e diluído em quantidades restritas de água. / The pesticides used in agriculture areas can be transported to water bodies of the local hydrographic basin in several ways. Moreover, these chemicals are commonly used in aquaculture to fish parasite control. The teflubenzuron (TFB) is a registered insecticide in some European countries to this use. The possible effects of the TFB and environmental risk can be evaluated initially in laboratory conditions by tests of acute toxicity with internationally elected organisms. The objectives of this study were to evaluate the acute toxicity and the environmental risk due to agriculture and aquaculture use of TFB, based on the values of EC50 and LC50 estimated in tests with Daphnia magna, Lemna minor and Poecilia reticulata, internationally used as bioindicators organisms. The acute ecotoxicity tests were performed in accordance with national and international standards for these species. The EC50-48h estimated to D. magna was 0,00026 mg.L-1, which characterizes that as very highly toxic insecticide for this species. For L. minor, EC50-7d was estimated 1.176,16 mg.L-1, and P. reticulata LC50-96h, 2.707,87 mg.L-1, which classified the TFB as practically non-toxic to these species. Due to the high toxicity of the TFB to daphnids, even in little contamination, can cause a loss of equilibrium in the aquatic food chain. To minimize the environmental risk, the TFB can be used in a controlled way and diluted in limited quantities of water.
