Full textAbstract:
This transversal and comparative study investigated the use of the Semmes-Weinstein Monofilaments (SWM) and the Antineoplastic Induced Neurotoxicity Questionnaire (AINQ) to detect sensory neuropathy in persons receiving neurotoxic chemotherapy. A sample of 117 persons were divided into 02 groups: patient and control. The patient group included 87 persons who had completed at least one chemotherapy cycle with oxaliplatin or taxanes (paclitaxel or docetaxel). The control group included 30 people who had never received any antineoplastic treatment. The project had IRB approval and met the Resolution 196/96 recommendations. The data were collected using the following tools: a Sociodemographic Form, a Clinical Data Form, the ECOG Performance Scale, the AINQ, and a SWM Kit. Data were entered into the SPSS version 15.0, cleared up and analyzed using descriptive, correlational and comparative statistics, with a significance level of 5%. The mean age of the patients was 54 years (SD=11.9 years) and of the control group was 44 years (SD=12.7 years). Both groups were composed mainly by married women, with low socioeconomic and educational level. Functional performance was significantly different between the two groups (p=0,000). Breast cancer was the most frequent type of cancer in the patients, followed by colorectal and gynecologic tumors. The majority were in paclitaxel (68.9%; n=60) and oxaliplatin (28.73%; n=25) protocols. The AINQ was validated and showed good reliability, with a Cronbach alpha of 0.863. The results of the paired samples T- test confirmed good internal consistence. There were statistically significant differences (p<0.001) for all symptoms between the groups. Chemotherapy Induced Peripheral Neuropathy (CIPN) symptoms were not related to the type of the chemotherapy drug (p=0.478). In the patients group, the hand esthesiometry showed higher sensory changes frequency in all points of the ulnar, median and radial nerves (p<0.05). The patients hand sensory changes varied from the blue monofilament (0.2g) to the red x (4g). In the control group, the worst sensory change was detected by the violet monofilament (2g). Results of the feet estesiometry showed significant differences between the groups (p<0.05). Sensory changes were more severe in the patients, ranging from the violet monofilament (2g) to complete sensory loss in certain points. A comparison between the tools had Kappa values of 0.193 in the patients group, 0.204 in the control group, and of 0.320 for the total sample (p<0.05). The correlation between the AINQ and the Esthesiometer was positive and moderate (=0.357, p<0.001). The study showed that both the AINQ and the Esthesiometer can be useful tools for CIPN detection in oncology.Estudo de corte transversal, comparativo, que investigou o uso dos Monofilamentos de Semmes-Weinstein (MSW) e do Questionário de Neurotoxidade Induzida por Antineoplásicos(QNIA) na detecção de neuropatia periférica sensorial em pessoas tratadas com quimioterápicos potencialmente neurotóxicos. A amostra foi composta por 117 indivíduos, subdividos em 02 grupos: pacientes e controles. O grupo pacientes foi composto por 87 pessoas em tratamento com oxaliplatina ou taxanes (paclitaxel ou docetaxel) e que haviam realizado no mínimo um ciclo de quimioterapia. O grupo controle foi composto por 30 pessoas jamais submetidas a qualquer tratamento antineoplásico. O projeto foi aprovado em todas as instâncias necessárias e atendeu às recomendações da Resolução 196/96. Para a coleta de dados foram utililizados os seguintes instrumentos: Formulário para dados sociodemográficos; Formulário para dados clínicos e Escala de Performance de ECOG; QNIA e Kit Estesiômetro Sorri®. Os dados foram inseridos no programa SPSS, versão 15.0, onde foram tratados e analisados, utilizando-se estatística descritiva, correlacional e comparativa, considerando-se um nível de significância de 5%. A média de idade dos pacientes foi de 54 anos (DP=11,9anos) e 44 anos para o grupo controle (DP=12,7 anos). Ambos os grupos foram compostos por mulheres casadas, com baixos níveis de escolaridade e socioeconômicos. A capacidade funcional dos grupos evidenciou significativa diferença entre eles (p=0,000). No grupo pacientes, o câncer de mama foi o mais frequente seguido pelos tumores de colon/reto e ginecológicos. Houve predomínio de protocolos envolvendo paclitaxel (68,9%; n=60) e oxaliplatina (28,73%; n=25).Na validação do QNIA, evidenciou-se boa confiabilidade do instrumento, com um alfa de Cronbach igual a 0,863. O teste de amostras pareadas evidenciou boa consistência interna. Na comparação entre os grupos foram encontradas diferenças estatisticamente significativas entre eles (p<0,001), para todos os sintomas avaliados. Os sintomas de NPIQ (Neuropatia Periférica Induzida por Quimioterapia) não estiveram relacionados ao tipo de quimioterápico utilizado (p=0,478). Os resultados da estesiometria nas mãos demonstraram que em todos os pontos a frequência de alterações de sensibilidade foi superior nos pacientes do que nos controles (p<0,05). Nas mãos, a perda sensorial no grupo de pacientes variou desde o monofilamento azul (0,2g) até o vermelho x (4g). No grupo controle, a pior alteração de sensibilidade foi apenas até o monofilamento violeta (2g). Na estesiometria dos pés, também verificamos diferenças estatisticamente significativas entre os grupos em todos os pontos avaliados (p<0,05). Para o grupo de pacientes, a alteração de sensibilidade foi mais grave, variando de violeta (2g) até a não percepção de nenhum dos filamentos. Na comparação dos resultados obtidos entre os instrumentos, verficamos que os valores de Kappa para o grupo pacientes foi de 0,193; 0,204 para o grupo controle e para a amostra total de 0,320, todos eles com p<0,05. Apesar dos baixos valores de kappa, os resultados obtidos com o QNIA e Estesiômetro no grupo de pacientes tiveram correlação positiva e moderada( = 0,357; p<0,001). Concluiu-se que tanto o QNIA quanto o Estesiômetro podem ser instrumentos usados na prática oncológica para detecção da NPIQ.

La diabetes mellitus tiene una serie de complicaciones, entre las que tenemos la neuropatía diabética que predispone a la amputación de las extremidades inferiores. El presente estudio tiene la finalidad de comparar las respuestas obtenidas a través de la técnica de prueba de sensibilidad presora con monofilamento Semmes Weinstein en relación con estudio electrofisiológico en la identificación temprana de neuropatía diabética subclínica en un grupo de pacientes del Hospital Central de la Policía que acudieron desde enero del 2000 hasta mayo del 2000. Se solicitaron los permisos correspondientes tanto a los servicios como a los pacientes antes de iniciar el estudio, se acudió puntualmente a las consultas para captar el número más real posible de pacientes teniendo en cuenta las características de los mismos. Además, se elaboró una lista de asignación de recursos (tanto humanos como materiales), un presupuesto y un cronograma de actividades. Durante el periódo de estudio que comprendió los meses de enero a mayo del 2000 se ingresaron 59 pacientes al estudio ya que cumplían los criterios de inclusión, 4 pacientes no concluyeron el estudio ya que faltaron a sus citas para los exámenes respectivos. El mayor porcentaje de pacientes se encuentra entre los 46 y 50 años. El estudio concluye que el método del monofilamento Semmens Weinstein es una prueba que guarda una relación significativa con respecto a la velocidad de conducción sensitiva, se obtuvo respuesta anormal al monofilamento en todos los pacientes con velocidad de conducción sensitiva alterada. Sin embargo, se deben incluir dentro de los pacientes de riesgo para neuropatía a los pacientes con diabetes subclínica, es decir a los que tienen antecedentes familiares y han tenido un examen de glucosa en más de 110mg/dl.

Die altpreussische Sprache ist sehr wichtig für die Baltistik und Indogermanistik. Die spärlichen Sprachdenkmäler und die reichen Angaben des altpreussischen Namengutes sind eine wichtige Quelle der lexikalischen Forschungen. Die Forschungen der Eigennamen, die eine beständige Schicht der Sprache bilden, geben wichtige Auskunft über die Eigenschaften der toten Sprache, über ihre Phonetik, Lexik und Morphologie, die in Eigennamen fixiert sind, aber in den Apellativa nicht mehr vorkommen. In der vorliegenden Magisterarbeit werden 567 samländische Personenamen, aufgeschrieben im 13.–16. Jahrhundert, analysiert. Man kann über die eingliedrige Personenbezeichnung sprechen. Es ist zu bemerken, dass man die Anfänge der zweigliedrigen Personenbezeichnung feststellen kann. Das Ziel der vorliegenden Arbeit ist die samländischen Personennamen, die in der Studie von R. Trautmann Die altpreussischen Personennamen verzeichnet sind, zu untersuchen in Hinsicht auf Bildung und Herkunft. Es werden ostbaltische Parallelen und, wenn nötig, deutsche und slawische, angeführt. Die altpreussischen Personennamen werden nach dem Alphabet beschrieben, weil die Bildung und Herkunft vieler Personennamen unklar ist. Alle vorhandenen Etymologien werden angeführt. Es wird versucht auch eigene Etymologie vorzuschlagen.

Full textAbstract:
The Internet was a catalyst for refiguring the previous models of media relationships. For many, the Internet is a medium that liberates individuals from the centralised and asymmetrical power structures of traditional mass media and other social institutions in particular, the boundaries set by the nation and the state. For other people, the Internet increases the capacity for surveillance and control. This dissertation argues for a fluid conception of the operations of power and resistance on the Internet that takes into account the various discourses which play a part in determining agency and subjectivity.
It examines and balances the narratives of liberation and oppression against each other: for, just as the developments in Internet technology contribute to changes in discourse, so too existing or prior discursive limits and relations of power affect Internet culture and technology.
In the process of analysing the interplay of different discourses on the Internet, this dissertation takes into account transnational and national cultural flows and the insights that conceptual work on globalisation, transnationalism, and cosmopolitanism can provide. The case studies are concerned with change and centre on the use of the Internet to effect this change; they include: the Singaporean Internet, a thread about Asian culture and Australia, the representation of oppression and the formation of Chinese diasporic collectivities, and anti capitalist networks. Through these case studies, the dissertation examines the degree to which the nation-state can regulate and affect the discourses at play on the Internet as well as the agency of participants in countering and maintaining these discourses. This dissertation also analyses activists use of the Internet to form transnational networks. It discusses the limitations of their work including problems with representation.

Full textAbstract:
This research intended to investigate possible consequences in the school life of teenagers, from their family configurations way. The issue was approached by the Psychoanalysis bias and has as its starting point the evolution of the concept of Father, especially in the works of Freud and Lacan. In addition, there was the necessity of understanding part of the historical path of the changes in family configurations, as well as some of the issues involving the problems presented in the school environment. The research proposal has origins in the malaise in education scenery seen from the researcher experience as a History teacher in public and private education systems. Among different situations, one stands out in that environment, which refers to the usual speech that relates directly experienced problems in the educational environment to some students family configuration, due to the fact that they differentiate from the ones said traditional (father, mother and offspring). In this sense, a question arose: did those students from family configurations which are different from the model biological father, mother and child, for this reason, contribute to the increase in problems at school? The choice of subjects was made through the indications from leaders of two public schools and a private one in the city of Piumhi (one was public and the other was private) and Capitólio (public), both in the State of Minas Gerais. Furthermore, a documentary analysis of the students was made. The intersection of information from both data sources allowed the choice of 14 subjects who composed this research. The semi-structured interviews with the teenagers were another instrument used as data collection. To support some of the hypotheses that emerged after the data analysis, it was necessary a theoretical study about the concept of femininity in the psychoanalytic theory of Lacanian orientation, aiming the attempt to understand the relationship of adolescents and their mothers, that seems to influence their successful school lives. Besides, it was found that, in a general way, mothers have strong influence in their children school life, while the fathers are partially or totally absent. At most, it was realized that the problems experienced in the school environment relate more to the inadequacy of the school system than to the type of family configuration of which students are part of.Esta pesquisa pretendeu investigar possíveis consequências na vida escolar de adolescentes, a partir do modo das suas configurações familiares. A questão foi abordada pelo viés da Psicanálise e tem como ponto de partida a evolução do conceito de Pai, em especial nas obras de Freud e Lacan. Além disso, houve a necessidade de entender parte da trajetória histórica das mudanças das configurações familiares, bem como de algumas das questões que envolvem os problemas presentes no ambiente escolar. A proposta de pesquisa tem origens no cenário de mal-estar na educação observado a partir da experiência do pesquisador como professor de História nas redes pública e particular de ensino. Entre as diversas situações, destaca-se, nesse meio, o discurso usual que relaciona diretamente problemas vivenciados no ambiente educacional à configuração familiar de alguns alunos, por se diferenciar daquela dita tradicional (pai, mãe e prole). Nesse sentido, questionou-se: será mesmo que aqueles alunos provenientes das configurações familiares distintas do modelo pai, mãe e filho(s) biológico(s), por esse motivo, contribuiriam para o aumento dos problemas na escola? A escolha dos sujeitos foi feita por meio de indicações das dirigentes de duas escolas públicas e uma privada nos municípios de Piumhi (uma estadual e outra particular) e Capitólio (estadual), ambos no estado de Minas Gerais. Além disso, foi realizada uma análise documental dos alunos. O cruzamento das informações de ambas as fontes de dados possibilitou a escolha dos 14 sujeitos que compuseram esta pesquisa. As entrevistas semiestruturadas com os adolescentes foi outro instrumento usado como coleta dos dados. Para embasar algumas das hipóteses surgidas após a análise dos dados, foi necessário um aprofundamento teórico sobre o conceito de feminilidade na teoria psicanalítica de orientação lacaniana, no sentido de tentar entender a relação de adolescentes e suas mães, que parece influenciar suas vidas escolares de sucesso. Além disso, foi possível constatar que, de modo geral, as mães apresentam forte influência na vida escolar dos filhos, ao passo que os pais mostram-se parcial ou totalmente ausentes. No mais, percebeu-se que os problemas vivenciados no ambiente escolar relacionam-se mais com a inadequação do sistema escolar do que com o tipo de configuração familiar da qual os alunos fazem parte.

Darbe sinchroniškai tiriama kalbėjimo veiksmažodžių semantinė ir formalioji struktūra, skiriamas dėmesys lietuvių grožinių kūrinių dialoginei kalbai ir ją įforminančioms kalbėjimo leksemoms. Kadangi šiame darbe lietuvių kalbos kalbėjimo veiksmažodžiai nagrinėjami semantiniu aspektu, todėl iš pradžių aptariamos pagrindinės leksinės semantikos sąvokos, apibūdinama kalbėjimo veiksmažodžių semantinė grupė (KSG).
Lingvistinėje literatūroje žodžio reikšmės ir jos raiškos formos vienovė vadinama semema. Į kalbėjimo veiksmažodžių semantinę grupę buvo atrinktos leksemos su sememomis „bendrauti žodžiais“, „perduoti informaciją, mintis, jausmus ir pan.,“ kurios įvardija kalbėjimo procesą. Sememos jungtos į KSG pagal jų komponentinės struktūros panašumą. Savo ruožtu sememos struktūra sudaryta iš minimalių semantikos vienetų – semų, kurios smulkiau nebeskaidomos. Kalbėjimo veiksmažodžių reikšmių analizė pagrįsta jų skaidymu į mažesnius reikšminius elementus, todėl tyrimui taikoma komponentinė analizė.
Kalbėjimo veiksmažodžių formaliosios struktūros analizė, t. y. derivacinių santykių tinklas, pirminių kalbėjimo veiksmažodžių šaknų fonologinė sudėtis, charakterizuoja tam tikros sistemos struktūros požymius. Šiame darbe nagrinėjama pirminių kalbėjimo veiksmažodžių šaknies struktūra, vokalizmo ir konsonantizmo padėties ypatumai, nustatomi būdingiausi šios semantinės grupės šaknų struktūriniai modeliai.

As Lithuanian speaking verbs are analysed there in the semantic aspect, so in the beginning of the work the subject of the investigation is the meaning of the main semantic groups. Besides, the semantic group of the speaking verbs (KSG) is researched. In the linguistic literature the meanings of the word and the unity of its expressiveness is called the semema. The lexemes with the sememas “to communicate orally”, “to transmit information, thoughts, emotions and etc.” were chosen to the semantic group of the speaking verbs. They describe the process of speaking. The sememas are included in KSG according to the principle of the similarity of their complex structure. The structure of the semema itself is built of the smallest semantic units called semes. However, there are good reasons to say that the analysis of the meanings of the speaking verbs proves that they are divided into the smaller elements. That is why the work presents the complex analysis of these verbs. The analysis of the formal structure of the speaking verbs, i.e. the net of the derivation relationship, the structure of the basic phonemic speaking verbs’ branches, is characterized by the certain signs of the structure. The work investigates the structure of the basic speaking verbs’ roots, as well as the peculiarities of consonant and vowel... [to full text]

Det här arbetet studerar med hjälp av en attitydundersökning förhållandet mellan anställdasoldater och Försvarsmakten i syfte att utveckla förståelsen för soldaters commitment till sinarbetsgivare. Frågeställningen lyder Hur ser soldaters relationer ut till arbetsgivarenFörsvarsmakten? Arbetets teoretiska grund hämtas i begreppet relationship commitment och närmare bestämtden del som benämns attitudinal commitment. Den begreppsdefinition som nyttjas bygger ihuvudsak på Meyer och Allens (1991) tre komponenter av relationship commitment, det villsäga affective commitment (känslomässig), continuance commitment (kalkylativ) ochnormative commitment (normativ). Begreppsdefinitionen inkluderar även åtta påverkansfaktorer som var och en ges en tydlig knytning till respektive komponent avrelationship commitment. Påverkansfaktorerna utgörs av personlig kompetens, deladevärderingar, förtroende, upplevelser, relationsfördelar, relationsavvecklingskostnader samtskyldigheter och tvingande miljö.Till skillnad från många tidigare studier görs här en tydlig koppling mellan påverkansfaktoreroch komponenter. Vidare studeras relationen mellan arbetstagare och arbetsgivare inomoffentlig sektor vilket även det är relativt ovanligt. Tidigare har framförallt relationer mellanorganisationer inom privat sektor eller olika former av nätverk studerats.Undersökningens resultat visar att soldaternas relation med Försvarsmakten framföralltbygger på en känslomässig grund där personlig kompetens och upplevelser samt deladevärderingar har störst betydelse. Därtill kan föras att även förtroende har viss betydelse förrelationen. Inom den kalkylativa komponenten spelar en förväntan om personlig utveckling enviss roll, men i övrigt har komponenten begränsat inflytande på relationen. I studienkonstateras också att det i princip inte finns någon normativ grund i soldaternas relation medFörsvarsmakten.Using an attitude survey, this essay studies the relationship between employed soldiers and their employer the Swedish Armed Forces in order to develop an understanding of therelationship between these parties. The research question is: What do soldiers' relationships totheir employer, the Swedish Armed Forces, look like?The theoretical basis of the study is build on the theories of relationship commitment, andmore specifically the part that can be linked to attitudinal commitment. The conceptualdefinition used is mainly based on Meyer and Allen's (1991) three components of relationshipcommitment, namely affective commitment (emotional), continuance commitment(calculating) and normative commitment (normative). The concept definition also includeseight influencing factors, each given a clear linkage to the respective component ofrelationship commitment. The influencing factors are personal competence, shared values, trust, experiences, relationship benefits, relationship termination costs, obligations andimperative environment.Unlike many previous studies done in this area, a clear link between the influencing factorsand their respective components is defined. In addition, the survey covers the relationshipbetween workers and employers in the public sector which is also relatively rare. Previously,mainly relationships between organizations in the private sector or in various forms ofnetwork have been studied.The results of the survey show that soldiers' relationship with the Swedish Armed Forces arebased in particular on an emotional basis, where feelings of personal competence, desire forexperiences and shared values are most important. In addition, trust has some but lesssignificance for the relationship. Within the caculating component an expectation of personaldevelopment play a certain role but otherwise the component has limited influence on the relationship. In principle, there is no normative basis in the soldiers' relationship with theSwedish Armed Forces.Keywords:

Full textAbstract:
Many systems of Knowledge Representation exist, but none were designed specifically for general purpose large scale natural language processing. This thesis introduces a set of metrics to evaluate the suitability of representations for this purpose, derived from an analysis of the problems such processing introduces. These metrics address three broad categories of question: Is the representation sufficiently expressive to perform its task? What implications has its design on the architecture of the system using it? What inefficiencies are intrinsic to its design? An evaluation of existing Knowledge Representation systems reveals that none of them satisfies the needs of general purpose large scale natural language processing. To remedy this lack, this thesis develops a new representation: SemNet. SemNet benefits not only from the detailed requirements analysis but also from insights gained from its use as the core representation of the large scale general purpose system LOLITA (Large-scale Object-based Linguistic Interactor, Translator, and Analyser). The mapping process between Natural language and representation is presented in detail, showing that the representation achieves its goals in practice.

Full textAbstract:
L'analyse du discours sur la famille et la parenté aristocratiques permet d'étudier les rapports entre autoreprésentation aristocratique, représentation cléricale et réalité sociale. La famille est un phénomène historiquement construit par la pratique et le discours. Elle apparaît comme un groupe cognatique structuré par la consanguinité, polarisé par la cellule conjugale. Les aristocrates s'autoreprésentent et mettent en pratique leur parenté vécue selon leurs besoins ; les c1ercs composent des récits interprétatifs et souvent moralisateurs appuyés sur des modèles bibliques et une vision providentielle du monde. La Chronique de Thietmar de Mersebourg donne accès à la conscience de soi d'un individu, évêque membre d'un groupe parental aristocratique et montre comment s'articulent et sont vécues ces différentes identités. La mémoire, l' oubli et les affects des auteurs et des acteurs interviennent dans la composition de chaque texte, qui défend une interprétation orientée de la réalité.

A paternidade tem se destacado como tema de pesquisas em diferentes áreas e tem sido objeto de calorosas discussões em vários contextos da vida social. O debate que envolve as questões sobre paternidade no âmbito jurídico encontra solo fértil nessa arena de discussões sociais e de pesquisas científicas. As possibilidades de investigação para a Psicologia nesse contexto são amplas e convidam ao desenvolvimento de pesquisas como a que aqui se apresenta. Esse é o resultado de um trabalho de quatro anos, no qual foram pesquisados os enunciados da paternidade do discurso jurídico brasileiro, procurando compreender como se produz a norma jurídica, como se normalizam os sujeitos e, neste sentido, como a norma jurídica é subjetivada pelos sujeitos, no que se refere à paternidade. A análise debruçou-se sobre documentos da jurisprudência brasileira. Foram pesquisadas dezenas de acórdãos disponíveis nos sites dos Tribunais de Justiça de Santa Catarina e do Rio Grande do Sul, com o descritor: paternidade. Após leitura e releitura do material arquivado realizou-se análise do discurso ancorada no referencial teórico de Michel Foucault. A análise realizada permite afirmar que os jogos argumentativos acerca da paternidade na jurisprudência brasileira deslocam-se fugidiamente de uma modalidade a outra por meio de práticas discursivas descontínuas que se cruzam e se complementam, mas que também, se excluem, se rompem. O discurso jurídico além de definir posições a serem ocupadas pelos operadores do Direito, também constitui um sujeito sobre o qual esses discursos incidem. Produz, assim, um regime de verdade sobre a paternidade que se estabelece discursivamente e fabrica pais. Regime de verdade ao qual se relacionam práticas institucionalizadas de poder # cujas instâncias dos tribunais, das novas tecnologias médico-legais e da família representam apenas uma parcela dessas dimensões institucionais. Assim, a paternidade não é uma essência inerente aos homens ou sua existência em forma concreta. Para que os homens sejam efetivamente inseridos na paternidade, ligados a ela, é necessária uma série de operações complexas por meio das quais eles se encontram vinculados aos dispositivos de produção dos diferentes e múltiplos modelos de paternidade. O Direito produz sujeitos por meio de seus dispositivos. Dispositivos engendrados por relações de poder e formas de funcionamento de saber que se encontram firmemente enraizadas naquilo que constitui as relações sociais no âmbito da paternidade.

A tese investiga o conceito de Ornamento no arquiteto e teórico Gottfried Semper (1803-1879), quem elabora, em meados do século XIX, importante teorização deste elemento arquitetônico. Destina-se a demonstrar que, em meio a um processo de depreciação semântica vigente na época, Semper procura restabelecer o status quo do Ornamento, consagrando a ele uma importância fundamental para os indivíduos e suas instituições sociais. Os vínculos tradicionais entre Ornamento e noções clássicas como Estilo e ordem são reforçados e atualizados pelo autor, considerando o contexto da época. Para este estudo, a investigação considerou dois momentos. Primeiramente, adotou-se um recuo temporal, trabalhado na longa duração, com o intuito de se apresentar um quadro sintético de noções e conceitos interdependentes que estruturaram o conceito de Ornamento na Tradição Clássica. Aqui a escrita foi organizada a partir da observação atenta às transformações dos sentidos atribuídos ao termo, aos conceitos que giraram em torno dele e o constituíram como um componente imprescindível do que se compreende por Arquitetura na Tradição. Em um segundo momento analisou-se o conceito de Ornamento em Semper em meio ao contexto europeu de meados dos oitocentos, tendo em vista o enfraquecimento da legitimidade da Tradição Clássica e as implicações resultantes do desenvolvimento da indústria moderna. Considera-se que os escritos deste autor, na medida em que procuram atualizar o conceito de Ornamento, evidenciam parte do contexto de crise da ornamentação em Arquitetura, que, diferentemente do que costuma colocar a historiografia tradicional, iniciou-se bem antes da aurora do moderno. O Ornamento em Semper deve ser compreendido como um conceito que opera dentro da disciplina Arquitetura e que faz parte dos esforços do autor em reorganizá-la em meados do século XIX.This thesis investigates the concept of Ornament in the writings of the architect and theorist Gottfried Semper (1803-1879), who put forth an important theory about this architectural element in the middle of the nineteenth century. It aims to show that Semper tried to restore the status quo of the Ornament in the midst of semantic devaluation, thereby granting the Ornament essential prominence in social institutions and to individuals. This thesis also shows that the author reinforces and updates traditional connections between the Ornament and classical notions, such as Style and Order. In order to accomplish the above, this study considered two moments. Firstly, the concept of Ornament in Classical Tradition was presented using temporal regression in a long duration structure; the writing about this moment is organized according to transformations in the meanings attributed to the term Ornament, and to the concepts that revolved around it and constituted essential components of Architecture in Tradition. The second moment is that in which Semper\'s concept of Ornament is analyzed throughout the mid-nineteenth century European context; in this view, thelegitimacy of Classical Tradition is weakened, due in part to the development of modern industry. In seeking to update the concept of Ornament, Semper\'s writings make explicit the crisis of Ornamentation in Architecture, which began well before the dawn of modern time, unlike traditional historiography says. This thesis argues that the Semperian Ornament should be understood as a concept that operates within the discipline of Architecture and is part of the author\'s efforts to reorganize it in the mid-nineteenth century.

The food processing company Semper AB in Götene has, after implementing software for monitoring production down time,identified a need for improvements considering time consumption in the cleaning process of Torn 4.After conducting studies, evaluations and analyses within the production, a need for standardization and time determination for the process has been identified. The project has resulted in propositions for new work standards considering time consumption for the included operations within the cleaning process, as well as definitions regarding the steps conducted parallel to one another to reduce the required time and streamline the process.The problem which was initially identified, as visualized through Semper’s down time tracking soft-ware Axxos, has through the course of the project been clarified as a symptom of a neglected work around standardization on the studied object. The need for increased standardization, control and planning is called for from both production management and operators alike, hence the competence involving the process exists within the organization, but need to emphasize and make use of it is nec-essary in a more efficient way.Livsmedelsföretaget Semper AB i Götene har efter implementering av mjukvara för stoppuppföljning identifierat behov av förbättringar med avseende på tidsåtgång i sin rengöringsprocess på Torn 4.

Fidele a la tradition seculaire de dresde, ville de la musique, la cour de saxe se dote le 12 avril 1841 d'un nouvel opera, le premier construit, de 1838 a 1841, par l'architecte gottfried semper dans le style neo-renaissance. Le premier opera de semper sera le theatre de la creation de nombreuses oeuvres dont rienzi, der fliegende hollander et tannhauser de richard wagner. Le 21 septembre 1869, ce bel edifice est detruit par un incendie. La cour de dresde fait alors de nouveau appel a gottfried semper, ainsi qu'a son fils manfred, pour edifier, du 26 avril 1871 au 2 fevrier 1878, un second opera de style neo-renaissance. Le second opera de semper atteindra sous la baguette des chefs d'orchestre ernst von schuch, fritz busch et karl bohm un niveau musical inegale jusqu'a nos jours, et verra entre autres les creations de la majorite des operas de richard strauss. Le 13 fevrier 1945, a la fin de la seconde guerre mondiale, le terrible bombardement de dresde detruit entierement l'interieur de l'opera. Apres plusieurs annees de reflexion, la r. D. A. Decide d'entreprendre, le 25 juin 1977, avec l'architecte wolfgang hansch, la reconstruction et la restauration, dans le style quasi original, de ce qu'on appellera le troisieme opera de semperFaithful to the secular tradition of dresde, a musical city, the saxe court was endowed with a new opera on the 12th april 1841, which was the first to be built, from 1838 to 1841, by the architect gottfried semper in the neo-renaissance style. In semper's first opera, numerous artistical creations took place, such as rienzi, der fliegende hollander and tannhauser by richard wagner. On the 21 st september 1869, this beautiful monument was destroyed by a fire. Thus, the dresde court called gottfried semper back, and his son manfred as well, to build a second opera in the same neo-renaissance style, between the 26th april 1871 and the 2nd february 1878. Owing to stick of such conductors as ernst von schuch, fritz busch and karl bohm, semper's second opera reached high musical standards, still unequalled nowadays, it became moreover the creative cradle of most richard strauss's operas. On the 13th february 1945, at the end of the second world war, the dreadful bombing of dresde entirely destroyed the inside of the opera

L’enfocament que es proposa en aquesta tesi es basa en el fet que hi ha un buit d’informació sobre l’optimització de l’examen de la solidesa reproductiva juntament amb els protocols d’anàlisi de semen en els equids, tal com es va veure al capítol anterior. A l’ase, no es van definir protocols específics per a l’anàlisi de semen, només per a mostres de sementals on hi ha un acord general sobre el protocol a utilitzar. Quan es comprova el tracte reproductor, s’utilitza una ecografia en mode B com a mètode de diagnòstic fàcil i no invasiu. D’altra banda, es pot utilitzar una ecografia Doppler polsada per estudiar la perfusió testicular de sang. Els índexs de Doppler pulsat de l’artèria testicular i les mides ASG van mostrar una correlació positiva amb la qualitat del semen en sementals i diferents espècies. Malauradament, no es van fer estudis d’aquest tipus en ruc, cosa que constitueix el primer objectiu de la tesi. No obstant això, quan es tracta d’anàlisi de semen, la tecnologia CASA representa el millor mètode objectiu que s’utilitza avui en dia. Permet obtenir dades quantitatives fiables, fins i tot si és necessari definir protocols que assegurin la consistència i l’aplicació universal dels resultats. Tanmateix, aquesta estandardització mai s’ha fet seguint un punt de vista integrador, que compon el segon objectiu general. Hi ha tres aspectes principals a tenir en compte a l’hora d’optimitzar les anàlisis automatitzades de semen mitjançant la tecnologia CASA-Mot, a saber, el tipus, la profunditat de la cambra de comptatge, la dilució i la velocitat de fotogrames d’adquisició d’imatges. Els avenços tecnològics van permetre ara l’adquisició d’alta freqüència de captura i, al mateix temps, el procés d’aquestes imatges en segons. A més, es va definir l’estructura de les subpoblacions d’espermatozoides en marcs més alts i la distribució SP entre les races dels sementals. El tercer objectiu era col·laborar en l’ús i la millora de la nova tècnica Trumorph®, per a l’anàlisi de morfologia de l’esperma que permet l’anàlisi d’espermatozoides immobilitzats vius.El enfoque defendido en esta tesis se basa en el hecho de que existe un vacío de información con respecto a la optimización del examen de solidez reproductiva junto con los protocolos de análisis de semen en équidos, como se vio en el capítulo anterior. En burro, no se definieron protocolos específicos para el análisis de semen, solo para muestras de sementales donde existe un acuerdo general sobre el protocolo a utilizar. Cuando se comprueba el tracto reproductivo, la ecografía en modo B se utiliza como un método de diagnóstico fácil y no invasivo. Por otro lado, la ecografía Doppler pulsado se puede utilizar para estudiar la perfusión sanguínea testicular. Los índices de Doppler pulsado de la arteria testicular y los tamaños de ASG mostraron una correlación positiva con la calidad del semen en sementales y diferentes especies. Lamentablemente, estos estudios no se realizaron en burro, lo que constituye el primer objetivo de la tesis. Sin embargo, cuando se trata de análisis de semen, la tecnología CASA representa el mejor método objetivo utilizado en la actualidad. Permite obtener datos cuantitativos confiables, incluso si es necesario para definir protocolos asegurando la consistencia y aplicación universal de los resultados. Sin embargo, esta estandarización nunca se ha hecho siguiendo un punto de vista integrador, que compone el segundo objetivo general. Hay tres aspectos principales a considerar al optimizar los análisis de semen automatizados mediante la tecnología CASA-Mot, a saber, el tipo, la profundidad de la cámara de recuento, la dilución y la velocidad de cuadros de la adquisición de imágenes. Los avances en tecnología permitieron ahora la adquisición de alta frecuencia de captura y al mismo tiempo el proceso de estas imágenes en segundos. Además, se definió la estructura de las subpoblaciones de espermatozoides en cuadros más altos y la distribución de SP entre las razas de sementales. El tercer objetivo fue colaborar en el uso y la mejora de la nueva técnica Trumorph®, para el análisis de la morfología espermática que permite el análisis de espermatozoides inmovilizados vivos.
The approach advocated in this thesis is based on the fact that there is a gap of information regarding optimization of breeding soundness examination along with semen analysis protocols in equids as seen in the previous chapter. In donkey, no specific protocols for semen analysis were defined, only for stallion samples where there is a general agreement about the protocol to use. When the reproductive tract is checked, B-mode ultrasonography is used as a non-invasive and easy diagnostic method. On the other hand, pulsed Doppler ultrasonography can be used to study testicular blood perfusion. Pulsed-Doppler indices of testicular artery and ASG sizes showed a positive correlation with semen quality in stallion and different species. Unfortunately, no such studies were done in donkey, which makes up the first objective of the thesis. However, when it’s about semen analysis, CASA technology represents the best objective method used today. It permits to obtain reliable quantitative data, even if it is needed to define protocols assuring the consistency and universal application of the results. However, this standardization has never been done following an integrative point of view, which composes the second general objective. There are three main aspects to consider when optimizing automated semen analyses by CASA-Mot technology, namely the type, depth of the counting chamber, the dilution, and the frame rate of image acquisition. The advances in technology allowed now the acquisition of high capture frequency and at the same time the process of these images in seconds. Also, was defined sperm subpopulations structure at higher frames and SP distribution between stallions’ breeds. The third objective was to collaborate in the use and the improvement of the new Trumorph® technique, for sperm morphology analysis which permits the analysis of alive immobilized sperm.

Full textAbstract:
The object of this thesis was to determine the independent predictive value of semen parameters obtained from the conventional analysis of semen by the methods advocated by the World Health Organisation in 1987, and of the descriptive semen categories also advocated by the World Health Organisation in 1987. The laboratory error in assessing sperm motility, density and morphology was quantified, and minimised by examining the predictive value of semen analyses performed by one technician. It was determined whether it is important to employ stringent criteria for recruiting fertile controls, by comparing semen parameters obtained from 'fertile' men who were recruited by two different methods. The relationship between demographic and clinical female factors and the cumulative conception rate was studied. The relationship between semen parameters and fertility was studied by two different methods. Firstly 'fertile' controls were compared to men who had attended an infertility clinic who were grouped by details of their partners. Secondly the relationship between semen parameters and the cumulative conception rate was studied after having considered known female factors. The relationship between information obtained from the history and physical examination of the male partner and the cumulative conception rate was studied, and it was determined whether semen analysis furnished predictive information independent of these features. This study also attempted to determine how many semen samples should be examined for optimum predictive value.

Full textAbstract:
Artificial insemination (AI) is a widely used part of the modern agricultural industry, with the number of animals inseminated globally being measured in the millions per anum. Crucial to the success of AI is that the sperm sample used is of a high Quality. Two factors which determine the quality of the sample are the number of sperm present and their motility. There are numerous methods used to analyse the quality of a sperm sample, but these are generally laboratory based, expensive and in need of a skilled operator to perform the analysis. It would, therefore be useful to have a simple and inexpensive system which could be used outside the laboratory, immediately prior to the insemination of the animal. Presented in this thesis is work developing a time of flight (ToF) technique which makes use of a quartz crystal microbalance (QCM), operating at 5 MHz, as the sensing element. Data is shown developing a device where a 50 μl sample of boar sperm is added to a liquid filled swim channel, which the sperm are allowed to self-propel down and attach to the surface of a QCM at the end. The attachment of the sperm to the surface causes a measurable frequency decrease in the QCM, aproximately 50 Hz. An average effective mass measurement was made using a QCM and gave a value of 8 ± 5 pg per sperm, which was used in conjunction with the frequency change to determine the number rate of sperm reaching the QCM. Additional data is presented to investigate the effect of environmental temperature on the ToF of the sperm, showing a decrease in ToF between 23 0C to 37 0C. The system was also used to investigate increasing the swim speed of the sperm by chemical means. A range of 20 μmol to 100 μmol of progesterone was added to the swim medium and the ToF was shown to decrease as a result. To further develop the system, large commercial electronics were replaced by smaller circuits built in-house. An oscillator circuit based on a Pierce oscillator was used to drive the QCM and a frequency counter circuit making use of a universal frequency to digital converter (UFDC-1) was used to measure the frequency of the QCM. ToF experiments were performed which showed these pieces of equipment to be effective for performing the analysis of sperm samples. The swim cell itself was also refined, resulting in a compact, modular design. Work was performed developing layer-guided, single-port acoustic resonators to replace the QCM as the sensing element in the sperm analysis device. A maximum mass sensitivity of 1110 Hzμg-1cm-2 was found for devices on a LiTaO3 substrate with a 6 μm guiding layer. While viscosity-density sensing experiments found a maximum sensitivity of 488 KHz Pa-1/2 kg1/2 for a 4 μm guiding layer.

A theoretical study showed that Al can greatly affect the efficiency of sheep breeding schemes provided fertility is maintained at the highest levels. Factors that affect the survival of ram spermatozoa during preservation were studied. A pH range between 6 and 7 was well tolerated. The addition of 4% (v/v) glycerol to the diluted ram semen in Tris buffer lowered the motility and survival of spermatozoa during 5 hours of storage at 30'C. Following insemination of chilled ram semen, with and without glycerol in the diluent, lambing percentages of 59% and 73% respectively were obtained. Ram semen was frozen in 0.25 ml straws using various cooling combinations. The optimal procedure was found to be to cool rapidly from 5'C to -120'C at -20'C/min. When semen so treated was compared in a fertility trial with semen frozen by the pellet method of Evans and Maxwell (1987), lambing percentages of 14% and 18% respectively were obtained. Attempts were made to formulate a vitrifying diluent for ram semen. A method was developed for the assessment of semen in highly concentrated cryoprotective solutions. Semen tolerated 10% concentrations of each of glycerol, acetamide and propylene glycol applied together, but when concentrations were raised above this level sperm mortality was very high. A simple spectrophotometric procedure for the objective assessment of vigour of ram semen was developed and tested. Raffinose 66 mM in the freezing diluent improved the post-thawing revival rate of spermatozoa from 46% to 71%, and increased the post-thawing recovery of the swimmingup vigour (P< 0.01). Raffinose treatment reduced the ATP content of semen but did not reduce the rate of glucose oxidation by diluted spermatozoa at either the pre-freezing or post-thawing stages. Frozen storage of ram spermatozoa as pellets was best achieved using two volumes of Tris buffer diluent containing 18% (v/v) egg-yolk, 6% (v/v) glycerol and 66 mM raffinose to one volume of semen. The diluted semen was chilled to 5'C and frozen as 0.10 ml pellets on dry ice. For frozen storage of ram semen in 0.25 ml straws, best results were obtained when the Tris buffer diluent contained 18% (v/v) egg-yolk, 9% (v/v) glycerol and 66 mM raffmose, and cooling was at a rate of -30'C/min from 5'C to -120'C. Non-return rates were 21%, 20% and 31% for ewes inseminated with semen samples frozen as standard 0.20 ml pellets, as raffinose containing 0.10 ml pellets, and as raffinose containing 0.25 ml straws respectively. Of the in vitro tests, only the swim-up test was correlated with non-return rates (r=0.904, P< 0.1). Post-thawing survival of the spermatozoa was improved by the addition of raffinose which had no deleterious effect on fertility.

Hvattum, Mari. "Poetics and practical aesthetics in the writings of Gottfried Semper." Thesis, University of Cambridge, 1999. https://www.repository.cam.ac.uk/handle/1810/265437.
Full textAbstract:
This dissertation presents an interpretation of the writings of the German architect and theorist Gottfried Semper (1803-1879). In his theoretical works, Semper addressed two main concerns. One was to develop an understanding of the ontological significance of art and architecture, the other was to render art and architecture the object of scientific investigation and prediction. The dissertation investigates the background and implications of these conflicting concerns. Semper located the origins of architecture in ritual action, more specifically, in the way such action was embodied in the techniques and motifs of artistic making. In doing this, he broke with the neo-classical notion of the origin of architecture as a building type, a real or ideal 'primitive hut'. This reinterpretation allowed Semper to develop original reflections on architectural meaning, emphasising architecture as a creative interpretation of human actions and situations rather than as a formal-stylistic phenomenon. Situating Semper in the context of neo-classical and romantic aesthetics, the first part of the dissertation investigates the significance of this reinterpretation. I argue that Semper, by emphasising the ontological and anthropological significance of artistic making, approximated a 'poetics of architecture' in an Aristotelian sense, in which architecture is understood as mimesis of praxis. On the basis of his revised genealogy of art and architecture, Semper sought a 'logical method' by which to establish a scientific explanation of the process and products of artistic making. This 'practical aesthetics', as he called it, was to serve as a vehicle for the interpretation, diffusion and production of art and architecture. The second part of the dissertation investigates this ambition, focusing in particular on Semper's reliance on the comparative method. By examining the use of the comparative method in fields like anatomy, linguistics and sociology - all mentioned by Semper as methodological ideals - the dissertation attempts to elucidate the epistemological and methodological presuppositions of Semper's practical aesthetics. Semper's 'poetics' and his 'practical aesthetics' form an ambiguous alliance. While the poetics presented art and artistic making as an ontological and anthropological phenomenon, the practical aesthetics rendered art a matter of epistemology and method. While previous Semper scholarship has tended to treat these aspects in isolation, I will look for the intellectual framework that allowed Semper to conceive of them as a unity. The third part of the dissertation locates this framework in the philosophical outlook of historicism. By investigating the historicist fusion of romanticism and positivism, I seek to understand the implications as well as the limits of Semper's 'method of inventing.'

Full textAbstract:
The purpose of this bachelor's degree project is to address the problem of automation of a storing system complex enough to be able to understand and manage the most important and critical aspects of the storage plant. The plant has been designed and built in a simulation program called Simumatik due to its obvious simplicity in comparison to what it would take to assemble it in the real plant.Therefore, some technical aspects have been integrated in connection with OPC-UA and with programming of CODESYS. Thus, a system with a variety of components has been proposed in aim to get as close as possible to a storing plant and a real distribution. The system includes ten conveyors. The bags are moved from the filling station to a door where the next operator take each bag.In turn, the resolution of the problem has been tackled from a realistic and general point of view so that all the final objectives of automation systems are achieved, such as the design and organization of a plant, control, and supervision.In general terms, the outcome of the final degree project is a deep analysis of current production, and a new storing processes with an automation solution and leveled production line as well. This automation would increase the flexibility of the operator as well as decrease the number of tasks of the operator and therefore it would be more efficient. The project begins by facing a problem in which the limitations are defined beforehand, which meets a complex and new requirement according to the development of a final degree project. This is equivalent to designing a storing plant with all the transport and distribution equipment in combination with sensors that provide information on the system.

Full textAbstract:
The aim of this study was to determine the efficacy of vaccination in preventing LSDV excretion in semen and negative effects on semen quality. Lumpy skin disease (LSD) is caused by a virus in the genus Capripoxvirus of the family Poxviridae. The virus has been reported to be excreted in the semen of experimental infected nonvaccinated bulls. Nevertheless, vaccination has been the most widely used method to reduce and prevent the spread of the disease. This work was done to determine the efficacy of lumpy skin disease vaccination in preventing the excretion of lumpy skin disease virus (LSDV) in semen of experimentally infected vaccinated bulls. It also determined further the effect of vaccination and experimental infection on semen quality. Six serologically negative bulls 11-16 months of age were vaccinated with an attenuated Neethling strain of LSD vaccine, and a repeated dose of vaccine was given twenty one days later. These bulls were then experimentally infected by intravenous injection with a virulent field strain of LSDV (V248/93). Six unvaccinated bulls were similarly infected to act as controls. All animals were observed for clinical signs, blood and semen was collected and evaluated twice a week until day 40 post vaccination and every two days until day 28 post-infection when the trial was terminated. Serology was done using the serum neutralization test and viraemia was determined by virus isolation. Semen was examined by polymerase chain reaction (PCR) for the presence of virus. Semen evaluation was done visually and microscopically. Two of the unvaccinated controls developed severe LSD, two showed mild symptoms and two were asymptomatic. No clinical abnormalities were detected following vaccination, and clinical signs were limited to mild lymph node enlargement in four bulls following challenge of the vaccinated bulls. There was a significant difference (P<0.05) in semen quality after experimental infection of the unvaccinated bulls. In the vaccinated bulls, semen quality showed no significant difference (P>0.05) following vaccination and challenge. Three of the vaccinated bulls were serologically positive at the time of experimental infection and four at the end of the trial. Five unvaccinated bulls were found to be viraemic during the course of the trial. No vaccinated bulls were found to be viraemic at any stage. Four unvaccinated bulls excreted the virus in their semen during the course of the trial. Viral nucleic acid was not detected in any semen samples following vaccination or challenge in vaccinated bulls. This study provides evidence that vaccination against LSD prevented the excretion of viral particles in semen. It also illustrated that LSD vaccination prevented any effect on semen quality after experimental infection with virulent virus.Dissertation (MSc (Production Animal Studies))--University of Pretoria, 2006.

This pre-test, post- test experiment examined the effects of mortality salience, frames of the military and military personnel, and regulatory focus on viewer attitudes toward the military, support for the military, and their perceptions of military personnelâ s criminal behavior. Participants viewed a short video clip from an episode of NCIS which contained either a sympathetic or non-sympathetic frame of the military and, in the treatment condition, a mortality salience reminder. Frame (sympathetic or non-sympathetic) had a significant effect on participant attitudes toward the military in the control condition when there was no mortality salience reminder present in the video clip. However, when participantsâ mortality was made salient, attitudes and support for the military did not change. Theoretical and practical implications and suggestions for future research are discussed.Master of Arts

Full textAbstract:
During the last half of the 20th century, the world pork industry has achieved astonishing developments in pig breeding. Now swine farms are larger, ownership more concentrated, and farms have become more industrialized. Artificial insemination (AI) plays an important role in animal breeding increasing utilization of genetically superior sires. Currently boars selected for commercial use as AI sires are evaluated on grow-finish performance and carcass characteristics. The objectives of this study were to (A) estimate genetic correlations between production and semen traits in the boar; average daily gain (ADG), back fat thickness (BF) and muscle depth (MD) as production traits, and total sperm cells (TSC), total concentration (TC), volume collected (SV), number of extended doses (ND), and acceptance rate of ejaculates (AR) as semen traits; (B) to model the variances and covariances of total sperm cells (× 109) over the active lifetime of AI boars; and (C) to compare multiple traits and random regression analyses applied to total sperm cells (TSC). Average heritability estimates were 0.39 for ADG, 0.32 for BF, 0.15 for MD, and repeatability estimates were 0.38 for SV, 0.37 for TSC, 0.09 for TC, 0.39 for ND, and 0.16 for AR. Semen traits showed negative genetic correlations with MD. Genetic correlations would indicate that current selection objectives are having a negative effect on semen traits. Therefore, current AI boar selection practices may be having a detrimental effect on semen production. In random regression analysis for total sperm cells, maximum log likelihood value was observed for sixth, fifth, and seventh order polynomials for fixed, additive genetic and permanent environmental effects, respectively. Best fit as determined by Akaike's Information Criterion was based on a model with sixth, fourth, and seventh order polynomials for fixed, additive genetic and permanent environmental effects, respectively. Best fit as determined by Schwarz Criterion was by fitting fourth, second, and seventh order polynomials for fixed, additive genetic and permanent environmental effects, respectively. Heritability estimates for total sperm cells ranged from 0.27 to 0.61 across age of boar classifications. Heritability for total sperm cells tended to increase with age of boar classification. The cyclic nature of heritability for total sperm cells that was observed over the active lifetime of boars may be due in part to number of observations across seasons limiting our ability to correct for seasonal effects on sperm production. In MTDFREML analysis, heritability estimates of 9, 12, 15, 18, 21, 24, and 27 months of age were, respectively, 0.28, 0.29, 0.26, 0.27, 0.30, 0.79, and 0.41. The results from MTDFREML seemed to be overestimated when compared to random regression. Therefore, random regression methods are the most appropriate to analyze semen traits as they are longitudinal data measured over the boars lifetime.

POOLPERM, PARIWAT. Factors Influencing Semen Quality and Fertilityin Boars. (Under the direction of Drs.Glen W. Almond and William L. Flowers)
The objectives of this researchwere 1) determine the influence of antibiotics on semen quality, 2) determinethe association among insulin-like growth factor I (IGF-I) in seminal plasma,semen quality, and subsequent fertility, and 3) retrospectively study theassociation among semen parameters and sow fertility. In the firststudy, the effects of gentamicin (GM), amikacin (AM), neomycin sulfate(NM), and penicillin-streptomycin (PS) in semen extender on the percentagesof motile (MOT), morphologically normal sperm (MOR), and sperm with normalacrosome (NAR) were examined. An in vitro penetration assay was conductedusing sperm cells on day 0 and day 5 of storage. GM and NM groupsshowed higher (p<0.05) MOT than other groups after 5 days of storage. No differences in penetration rate were found among treatments; however,the penetration rate decreased (p<0.05) on day 5 of storage.
In the second study, ejaculateswere collected and diluted in an extender (Vital?). Gilts (n=113)and sows (n=375) were inseminated with the extended semen in homogenetic-homospermicregimens. Farrowing rate (FR), total pigs born (TB) and born alive(TBA) were recorded. IGF-I was determined in seminal plasma by radioimmunoassay. Concentration of IGF-I from 204 ejaculates was 95.38 ± 3.56 ng/ml (mean± SEM) and total amount of IGF-I/ejaculate was 23.50 ± 1.20 µg. SeminalIGF-I differed (p<0.05) among genetic lines and had no effect (p>0.05)on MOT, MOR and NAR. However, IGF-I was associated (p<0.05) withsemen volume, sperm concentration and total number of sperm/ejaculate. No association between IGF-I level in seminal plasma and fertility indiceswas found.
The third study determinedthe associations among insemination parameters with subsequent fertilityof boar semen using data from the second study. MOR was associated(p<0.05) with fertility parameters. TB and TBA were associatedwith age of semen at the first insemination (SAGE) and number of spermper insemination dose (AIDOSE). With stepwise regression analysis,it was evident that FR was associated with semen volume, MOR and SAGE. Meanwhile, TB and TBA were associated with SAGE, AIDOSE and total numberof spermatozoa/ejaculate. In conclusion, the assessment of semencharacteristics may not necessarily delineate fertility between boars.

L’abeille domestique (Apis mellifera Linnaeus) joue un rôle crucial comme pollinisateur dans l’industrie de l’agriculture. Cependant, durant les dernières décennies, une mortalité des colonies d’abeilles a été observée partout à travers le monde. La conservation du sperme d’abeille est un outil efficace pour sauvegarder la diversité génétique. Sa conservation est possible à température pièce, mais la cryoconservation serait une meilleure méthode pour la conservation à long terme. Notre objectif général est de développer une méthode de cryoconservation de la semence d’abeille. L’hypothèse no.1 était que la cryoconservation de la semence d’abeille est plus efficace à long terme que les températures au-dessus de 0 °C. Nous avons évalué l’efficacité, basé sur la viabilité des spermatozoïdes, de deux températures de conservation: -196 °C et 16 °C. Après un an de conservation, la semence congelée avait une meilleure viabilité comparée à 16°C (76% ± 5% vs 0%; p < 0,05). Par la suite, la spermathèque des reines inséminées avec la semence cryoconservée a été évaluée par la migration des spermatozoïdes ainsi que la viabilité des spermatozoïdes. Il y avait beaucoup de variabilités dans nos résultats. Nous n’avons pas été en mesure de vérifier si l’ajout de la centrifugation après la conservation améliore la fertilité des reines après insémination. Toutefois, nos résultats confirment que la cryoconservation est une technique efficace pour conserver la semence d’abeille à long terme.Honey bees (Apis mellifera Linnaeus) are critical players in the agricultural industry for food production as they account for the vast majority of insect pollination. In the last decades, however, there have been dramatic losses of honey bee colonies worldwide. Coupled with instrumental insemination, conservation of honey bee sperm is an effective strategy to protect the species and their genetic diversity. Sperm storage is possible at room temperature, but for many mammal species, cryopreservation is the preferred method for the long-term storage of gametes. However, cryopreservation of honey bee drone semen is not optimized. Our overall objective is to develop a method of drone semen cryopreservation, therefore, two experiments were conducted. Hypothesis #1 was that cryopreservation of drone semen is more effective for long-term storage than at above-freezing temperatures. We therefore compared the efficacy based on sperm viability, of two honey bee semen preservation temperatures: frozen (-196°C) and 16°C. After 1 year of storage, frozen sperm viability was higher than at 16°C (76% ± 5% vs. 0%; p < 0.05), showing that cryopreservation is necessary to conserve semen in vitro. However, the cryoprotectant used for drone sperm freezing, DMSO (dimethyl sulfoxide), is toxic to queens after instrumental insemination. Hypothesis #2, therefore, was that centrifugation of cryopreserved semen to remove DMSO prior to insemination improves queen fertility. Our results indicate that centrifuging semen does not affect sperm viability (78% ± 3% vs 75% ± 4% viable sperm; p > 0.05). After queen insemination, both spermathecae and brood production were evaluated, but the results varied greatly, possibly due to the undesirable mucus present in the semen. Therefore, we cannot yet confirm that centrifugation improves queen health after insemination. Nonetheless, our study confirms that cryopreservation of honey bee sperm is necessary and possible for long-term conservation.

Welch, Jennifer Lynn. "Semen exosomes: intrinsic inhibitors of HIV-1 infection." Diss., University of Iowa, 2018. https://ir.uiowa.edu/etd/6661.
Full textAbstract:
Exosomes are cell-derived vesicles that circulate in bio-fluids and enclose cell-associated cargo, producing various consequences in intercellular communication and may contribute to microbial pathogenesis. Exosomes are similar in composition to enveloped viruses, making differentiation between exosomes and enveloped viruses difficult. Yet, exosomes and enveloped viruses may vary considerably in function. Exosomes produced from infected cells may incorporate viral material as they are simultaneously produced with viruses and depending upon the cargo, contribute to disease pathogenesis. Conversely, exosomes from uninfected cells may contribute to protection from infection. Exosomes from breast milk, vaginal fluid, and semen of healthy donors protect against HIV-1. The functional dichotomy of exosomes is unknown. Here, we focus on the function and physical qualities of exosomes found in semen (SE) and how these influence HIV-1. As semen is the major body fluid involved in HIV-1 transmission, exosomes from semen that regulate HIV-1 may contribute to the low incidence of HIV-1 sexual transmission in vivo.
Previous studies indicate healthy donor derived SE but not blood exosomes (BE) inhibit HIV-1 in a donor-independent manner. The composition and function of exosomes depends on the status of the exosome-producing cell. Thus, donor characteristics that alter the condition of exosome-producing cells may alter the antiviral phenotype of SE. Illicit drug use enhances HIV-1 replication, negatively affects male fertility, and alters exosome biogenesis pathways. Thus, illicit drugs may alter SE physical, composition, and functional properties. Indeed, SE from donors with a history of illicit drugs were altered in composition which correlated with a diminished ability to inhibit HIV-1. Similarly, because exosomes derived from HIV-1 infected cell cultures promote infection, donor HIV status may contribute to a proviral phenotype of exosomes. Infectivity studies by HIV-infected ART-naïve SE revealed that SE from healthy donors and HIV-infected donors are inhibitory, but BE are not inhibitory. Therefore, the inhibitory phenotype of SE is conserved regardless of donor HIV status. Significantly, BE and SE from HIV-infected ART-suppressed donors not only inhibited HIV-1, but contained inhibitory levels of antiretroviral (ARV) medications, indicating that body-fluid derived exosomes may act as carriers of ARV drugs.
Previous studies found that the antiviral mechanism of SE was targeted to multiple HIV-1 lifecycle steps; however, the mechanism of inhibition was unclear. Transcription specific analysis revealed that SE reduced HIV-transcription at multiple steps including association of transcription factors NF-kB and Pol II with the viral promoter, as well as transcription initiation and elongation. SE inhibited HIV-driven promoter activation and viral gene expression. Importantly, SE targeted inhibition of viral protein Tat transcriptional activities.
Overall, these findings from donor characteristics that may alter the condition of the cellular source of SE demonstrate that SE antiviral factor(s) is highly conserved. Illicit drugs alter SE-associated factors and may reduce SE inhibitory activities. However, HIV status does not affect the antiviral function of SE. Significantly, donor-ARV medications are associated with SE and BE indicating a potential role of exosomes in drug delivery in vivo. Mechanistically, SE suppress HIV-1 by targeting host and viral transcription factors that could be therapeutically exploited for novel anti-HIV strategies. These data emphasize the need for additional studies on the composition and function of SE to harness the antiviral potential of SE inhibitory factors.

Nas últimas décadas, muitos estudos têm sido realizados nas diferentes espécies com o intuito de se determinar os fatores envolvidos no processo da fragmentação do DNA espermático. A biologia molecular voltada à área da reprodução tem resultado em inúmeras técnicas para a avaliação da qualidade da cromatina e determinação da fragmentação do DNA espermático. Em trabalhos recentes, um novo teste denominado Halomax® tem se mostrado tão eficiente quanto a outros tradicionais para a avaliação da fragmentação do DNA espermático, apresentando como vantagens a sua praticidade e o fato não requerer o uso de equipamentos de alto custo. O presente experimento teve por objetivo comparar as raças Mangalarga Marchador (MM) e Quarto de Milha (QM) quanto à resistência à refrigeração, bem como utilizar o Teste Dispersão de Cromatina Espermática denominado Halomax® para avaliar a fragmentação da cromatina espermática do sêmen refrigerado dos garanhões dessas raças em duas temperaturas de armazenamento de sêmen refrigerado (5°C e 15°C). Os resultados deste trabalho demonstraram que não houve diferença entre as temperaturas de armazenamento (5°C e 15°C), mostran do que ambas são eficientes na manutenção da viabilidade espermática pelo período de 24 horas para ambas as raças estudadas. Além disso, foi observada uma característica espermática superior dos garanhões da raça Quarto de Milha quando comparada aos da raça Mangalarga Marchador, tanto nos parâmetros de velocidade espermática, avaliado pelo CASA, quanto com relação à fragmentação do DNA espermático, revelando uma maior sensibilidade dos animais da raça Mangalarga ao processo de refrigeração do sêmen
Many studies have been conducted in different species in order to determine the factors involved in the process of sperm DNA fragmentation. Molecular biology studies focused on the reproductive area has resulted in several techniques for assessing the quality of chromatin and sperm DNA fragmentation. Recently, a new test called HALOMAX ® has been shown to be as efficient as other traditional assessment of sperm DNA fragmentation, having the advantage of practicality and not require the use of expensive equipment. The aim of this study was to compare breeds Mangalarga and Quarter Horses for cooling resistance and use the Sperm Chromatin Dispersion Test called HALOMAX ® to evaluate the sperm chromatin fragmentation using two cooled semen storage systems (5°C and 15°C). Our results showed no difference between storage systems (5°C and 15°C), showing that both are effective in maintaining sperm viability for a period of 24 hours for both breeds studied. In addition, the Quarter Horse shown superiority in semen quality parameters assessed by CASA and sperm DNA fragmentation when compared with the Mangalarga, revealing higher sensitivity of the Mangalarga stallions for cooling semen
