Orientador: Irenilza de Alencar Nääs / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Agrícola / Made available in DSpace on 2018-08-21T11:14:36Z (GMT). No. of bitstreams: 1 Cordeiro_AlexandraFerreiradaSilva_M.pdf: 2367138 bytes, checksum: 6f75c3d8e468c0ebd6f7bceda2a2889b (MD5) Previous issue date: 2012 / Resumo: Entre os desafios da suinocultura no atual mercado competitivo destaca-se a rastreabilidade do produto que garante entre muitos pontos a questão do bem estar animal. O objetivo dessa pesquisa é estimar o gasto energético da vocalização de leitões em situação de dor e identificar suínos e sua condição de estresse pela sua vocalização. A primeira hipótese é que é possível estimar a energia gasta na vocalização. A segunda é que é possível identificar suínos pela sua vocalização e a terceira é que é possível identificar o estado de bem- estar ou estresse de suínos pela sua vocalização. Para tanto foram realizados três experimentos em granja comercial da cidade de Holambra- SP. No primeiro experimento foi analisada a vocalização de dois grupos de leitões durante a castração, um grupo com anestesia local e outro sem anestesia. A energia emitida no sinal vocal foi processada no software Matlab®. No segundo foi realizado a gravação da vocalização dos animais durante a caudectomia, marcação e castração. No terceiro experimento foi realizada a gravação da vocalização de leitões nas fases de maternidade, creche, crescimento e terminação em diferentes situações de estresse: sem estresse e com estresse térmico, fome, sede e dor. Para análises dos sinais de sons foi utilizado o software Praat®. Foi possível estimar a energia gasta na vocalização dos suínos e identificar condições de estresse pela sua vocalização. Porém, não foi possível identificar os animais pela sua vocalização / Abstract: Among the challenges in today's competitive market hog stands out for the product traceability, that ensures many points between the issue of animal welfare. The objective of this research is to estimate the energy expenditure of the vocalization of piglets in a situation of pain and identify pigs and their stress condition for their vocalization. The first hypothesis is that it is possible to estimate the energy expended in vocalization. The second is that pigs can be identified by their vocalizations, and the third is that it is possible to identify the state of well-being or stress of pigs by their vocalization. For this purpose, two experiments were conducted in commercial farm, in the city of Holambra-SP. In the first experiment, we analyzed the vocalizations of two groups of piglets during castration, one group with local anesthesia and the other without anesthesia. The energy emitted in the voice signal was obtained in Matlab ®. In the second experiment we analyzed the vocalizations of piglets during caudectomia, marking and castration. In the third experiment, it was performed recording of the vocalization of piglets in the stages of farrowing, nursery, growing and finishing in different situations of stress: no stress and thermal stress, hunger, thirst and pain. The software Praat® was used for analyzing of sound signals. It was possible to estimate the energy expended in the vocalization of pigs, and identify the stress conditions by using their vocalization as input variable. However, it was not possible to identify animals by their vocalization / Mestrado / Construções Rurais e Ambiencia / Doutora em Engenharia Agrícola

Feministiskt initiativ - en idéanalys

Wizelius, Akira January 2008 (has links)
Feminist initiative – an idea analysis. On the fourth of April in the year 2005 Feministic initiative (Fi) was created, it was an main response to the slow changes in the Swedish society, which claimed to establish an equal society. Equality has become one of the major indicators of a contemporary democratic society. The Swedish government has long proclaimed to reach this goal, but even though Sweden currently lies in the front among the democratic societies, while you consider equality issues, especially between the sexes, there is still a lot that need to be done in the Swedish society. Feministic initiative began as an organization and established a political party and participated in the election during the year 2006, but failed to reach a place in the parliament. Recently Feministic initiative said that they will participate in the upcoming election in the year 2010. It made me wonder which feministic ideals that Feministic initiative actually practices. Feminism is a broad ideology, and a reaction against the society that claims to be democratic but systematically oppresses women. This oppression created feminism; but there is different views of feminism, my main objective in this paper is to present a few different feministic directions. These are, radicalfeminism, marxistic feminism, liberalfeminism, socialistic feminism, post-modernfeminism and black (women’s) feminism. From these theories will I create a analyze frame and try to locate different kinds of feministic ideas within Feministic initiatives policy documents called F! for a feministic policy, election manifest and platform for Feministic initiative Thus, the main focus in this paper to do an idea analyze and focus on Feministic initiative, do they really use the different ideas expressed within the different types of feminism that I consider in this paper in a equal manner? The conclusion is that Feministic initiative is tendentious, Feministic initiative uses ideas, perspectives and expressions that are typical for radicalfeminism more than they use ideas, perspectives and expressions from other types of feminism.

Analytické metody v motorsportu / Analytical Methods in Motorsport

Růžička, Bronislav January 2013 (has links)
This dissertation is focused on proposal for simplified data analyze approach for sport-car vehicle dynamic evaluation with relationship to possibility for qualified estimation of set-up parameters influence for overall vehicle performance. In common practice can be usual overlapping effect caused by concurrent changes of car setup elements if performed in the same moment with resulting in not correct or hardly definable process determination for evaluation and decision about next steps in car development. For analyze of these multidimensional data is then chosen process with approach by Linear Regression Model (LRM). In dissertation is proposed basic philosophy with concern on specificity of car vehicle dynamics, performed experiment with defined inputs including analyze and interpretation method of obtained outputs. This methodic take into account also possibility for general application of multidimensional data analyses not only in motorsport, but as well for dynamic behavior diagnostics of technical systems where finding of optimal running condition depends on multi-parametric setup whose combination must reflect often changes of outer conditions too.

Den hälsodiskursiva praktiken : En etnografisk studie av hälsofrämjande aktiviteter på ett HVB-hem

Moberg, Anna, Nilsson, Malin January 2016 (has links)
På grund av oroligheter i världen skedde under år 2015 en kraftig ökning av asylsökande, där ibland även ensamkommande barn. Ökning av ensamkommande barn medförde en boendeproblematik för Sveriges kommuner, vilket lett till behov av flertalet nyuppstartade HVB-hem. Det fanns ett intresse av att studerades hälsofrämjande aktiviteter i kontexten, detta för att förstå dem som en del av en hälsodiskursiv praktik. Detta gjordes utifrån ett sociokulturellt perspektiv på lärande, diskurs analys samt ett helhetsperspektiv på hälsa. Därav har studien genomförts som kvalitativ studie med inspiration ifrån etnografisk forskning. Deltagande observationer utfördes vid tre tillfällen. Observationerna utfördes på två olika avdelningar på ett HVB- hem för ensamkommande pojkar. Genom ett hälsopedagogiskt perspektiv var avsikten med studien att synliggöra hälsodiskurser och dess betydelse för ungdomarnas lärande och skapande av hälsa. Kategorierna för studiens analyserade resultat återspeglar de hälsofrämjande aktiviteter som observerades. Teman för diskussionsdelen framanalyserats med utgångspunkt i studiens valda teorier och utföll i följande sex kategorier: Tidspassning, Vi och dem, Laganda och att ha trevligt ihop, Minskad förtäring av sötsaker, Regelföljning och självständighet samt Dubbla budskap. Av resultatet framkom det att den rådande hälsodiskursen tycks bygga på ett omedvetet helhetsperspektiv på hälsa. Det framkommer genom personalens utsagor att en strävans finns mot att skapa förutsättningar för att ungdomarna att utvecklas till självständiga individer, dock strider detta mot vad som kan ses i den hälsodiskursiva praktiken. Därav kan det tänkas att hälsa är ett ämne som kan behöva lyftas i praktiken. Då det var svårt att hitta relevant forskning i ämnet tycks även behov finnas av att bedriva forskning kring hur insatser på HVB-hem bör utformas för att uppnå ökad självständighet hos ungdomarna. / 2015 saw a sharp rise in unaccompanied children seeking asylum. This is due to turmoil in many parts of the world. The rise has brought housing problems for Sweden’s municipalities, with more housing and treatment facilities started as a result. A study was conducted, motivated by ethnography research. Participants were observed on three occasions, in two separate wards in a HVB resident for unaccompanied boys. Health promoting activities were observed, to gain an understanding of them for use from a pedagogic perspective. This was done using a sociocultural perspective in teaching, study analysis, as well as health in general. Through a health discourse perspective, the purpose of the study was to analyze health awareness in the children. The categories for the analysed results reflected the health promoting activities that were encouraged during the study. The study was analysed using the following six categories Punctuality, Us and them, Team spirit and getting along, Reduced sugar consumption, Following rules and independence, as well as Double standards. The results showed that the current health discourse is founded on a subconsciously overall perspective on health. Housing and HVB resident staff have the aim to create possibilities for the children to develop into independent individuals. It can be seen as a field that needs to be improved in practice, through staff education. Relevant data is lacking, further research is needed into what action is required to help the children reach independence.

Importância da detecção de mutações do gene ATP7B para o diagnóstico da doença de Wilson / The importance of detecting ATP7B gene mutations for the diagnosis of Wilson\'s disease

Araújo, Thiago Ferreira de 09 May 2014 (has links)
O diagnóstico da doença de Wilson (DW) é realizado por exames clínicos, laboratoriais, anatomopatológicos e de imagem. Mais de 500 mutações no gene ATP7B foram descritas como causadoras da DW. Para avaliar a importância da detecção de mutações no diagnóstico da DW em nosso meio, analisamos 35 pacientes com DW, 20 familiares de wilsonianos a partir de rastreamento familiar, 18 com hepatite crônica criptogênica e sete com insuficiência hepática aguda grave. Para o diagnóstico da DW foi utilizado o sistema de escore sugerido pela Sociedade Europeia para o Estudo do Fígado de 2012. Os dados demográficos, clínicos, laboratoriais e histológicos foram obtidos retrospectivamente. Obteve-se o DNA genômico de cada paciente a partir de sangue periférico e realizou-se o sequenciamento direto dos 21 éxons e suas bordas intrônicas do gene ATP7B. Todos os pacientes com DW apresentavam no mínimo quatro pontos. No grupo de rastreamento familiar o sequenciamento foi importante para o diagnóstico de DW em 14 familiares; no grupo de hepatite crônica criptogênica em oito pacientes e no grupo de insuficiência hepática aguda grave em três pacientes. Foi caracterizada uma família com cinco genótipos diferentes (dois homozigotos p.A1135Qfs/p.A1135Qfs e p.M645R/p.M645R), um heterozigoto composto (p.A1135Qfs/p.M645R) e dois heterozigotos simples (p.A1135Qfs/0 e p.M645R/0) com fenótipos variados. Foram detectadas duas mutações em heterozigose simples em pacientes com insuficiência hepática aguda grave. A mutação p.A1135Qfs e p.L708P foram as mais frequentes em todos os grupos. Foi identificada pela primeira vez a mutação p.M645R em homozigose. Concluímos que os resultados confirmaram que o sequenciamento do gene ATP7B foi útil: 1) para confirmar que as mutações p.A1135Qfs e p.L708P são as mais importantes na população brasileira; 2) para demonstrar que a mutação tida como a mais frequente na Europa, a p.H1069Q, tem bem menor importância em nosso meio, embora mais frequentemente do que o observado anteriormente; 3) para confirmar (ou excluir) precocemente o diagnóstico e evitar a realização de exames desnecessários e invasivos e iniciar (ou não realizar) o tratamento, com base mais sólida, em pacientes com hepatopatia crônica idiopática e em familiares de portadores de DW; 4) para definir o diagnóstico de DW em casos de insuficiência hepática aguda grave, diagnóstico ainda que tardio, mas de suma importância para realização de estudo familiar subsequente, 5) para identificação não esperada de heterozigotos simples e polimorfismos de significado ainda não esclarecido em pacientes com insuficiência hepática aguda grave; 6) para identificação de casos inusitados de três genótipos diferentes causadores da doença na mesma família (homozigose de duas mutações diferentes e heterozigose composta); 7) para melhor definir que a mutação p.M645R em homozigose tem potencial para desenvolver a DW, embora resultados de estudos em in vitro sugiram função normal da proteína defeituosa sintetizada; 8) para definir que há casos de doentes com a mutação p.M645R em heterozigose composta de evolução extremamente benigna, com diagnóstico após a quinta década de vida, com discretas alterações hepáticas. Porém há casos com evolução mais grave tanto do ponto de vista hepático quanto neurológico, possivelmente influenciados pelas mutações que a acompanham / Wilson\'s disease (WD) is an autosomal recessive disorder secondary to mutations in the ATP7B gene resulting in toxic accumulation of copper in various tissues. The diagnosis of WD is made by the analysis of clinical, laboratory, histological findings and imaging tests. More than 500 mutations have been described in the ATP7B gene as the cause of WD. In order to expand the knowledge of the importance of mutation detection in the diagnosis of WD, we analyzed 36 patients with WD, 20 individuals from family screening, 18 with cryptogenic chronic hepatitis and seven with severe acute liver failure. For the diagnosis of WD the International Scoring System suggested by the European Association for the Study of the Liver (EASL) in 2012 was used. Demographic, clinical, laboratory and histological data were obtained retrospectively. Direct sequencing of 21 exons and intron boundaries of ATP7B gene was performed in genomic DNA extracted from peripheral blood leucocytes of all subjects. All patients with WD have at least four points of the scoring system without considering the DPA challenge test. In the family screening group, sequencing was important for the diagnosis of DW in fourteen patients; eight patients in the group of cryptogenic chronic hepatitis, and three patients in the group of severe acute liver failure. Five different genotypes were identified in one family (two homozygous, p.A1135Qfs/p.A1135Qfs and p.M645R/p.M645R, one compound heterozygous p.A1135Qfs/p.M645R, and two simple heterozygous p.A1135Qfs/0 and p.M645R/0). Two patients with acute liver failure were detected as simple heterozygous. The p.A1135Qfs and p.L708P were the most frequent mutations in all groups. It is the first time p.M645R mutation was detected in homozygosity. The ATP7B gene sequencing was useful: 1) to confirm that p.A1135Qfs and p.L708P mutations are the most frequent in the Brazilian population; 2) to confirm that the most common mutation in Europe, p.H1069Q has lower frequency in our area; 3) to confirm (or exclude) an early diagnosis and to avoid unnecessary and invasive tests and to initiate (or not) the specific treatment with a stronger basis in patients with chronic liver disease and individuals from family screening of patients with Wilson disease; 4) to confirm the diagnosis, although late, of cases with severe acute liver failure, but very important to perform family screening; 5) to identify simple heterozygotes in patients with severe acute liver failure; 6) to describe unusual cases of three different genotypes of WD patients in a same family (two different homozygous mutations and one compound heterozygous); 7) to better define that p.M645R mutation in homozigosity develops WD, although the results from in vitro studies suggested a normal function for the defective synthesized protein; 8) to define that there are patients with p.M645R mutations in compound heretozigosity with a very benign clinical picture, with late diagnosis, after the fifth decade of life, with mild liver alterations. However, there are patients with a more severe clinical evaluation, hepatic or neurologic, probably secondary to the influence of the other mutation
