O ambiente costeiro é berçário natural para um grande número de espécies marinhas, principalmente onde ocorrem mangues e recifes, que funcionam como abrigo natural para a desova e início de vida de muitas espécies marinhas. A linha de costa está inserida nesse ambiente, pois representa o limite entre o mar e o continente, no alcance máximo das ondas, onde cessa a ação marinha efetiva. Entretanto, a dinâmica de movimentação das marés torna esse limite uma zona de fronteira de difícil demarcação e monitoramento. Além disso, as alterações geomorfológicas, muitas vezes catalisadas pelas interferências antrópicas, diminuem a capacidade de regeneração natural das praias, dificultando o gerenciamento desse ambiente. Em virtude disso, essa tese desenvolveu alguns experimentos para localizar e monitorar linhas de costa nas praias de Sauaçui e Japaratinga, localizadas no Estado de Alagoas Brasil, aplicando tecnologia de posicionamento dos sistemas GNSS (Global Navigation Satellite System), com base em um indicador de linha de costa com representação matemática, correspondente à máxima altura alcançada pelas marés nos últimos 20 anos, acrescida do run-up, correspondente ao espraio das ondas. O GPS (Global Positioning System), que a partir deste ponto será designado apenas GPS, consiste em um sistema de posicionamento por satélite pertencente ao GNSS e pode gerar posicionamentos no modo dinâmico relativo, com precisão de poucos centímetros e suas técnicas já vem sendo aplicadas em programas de gerenciamento costeiro em várias partes do mundo. Entretanto, as alturas geradas pelo GPS são elipsoidais e representam um problema para o uso desse sistema em aplicações que envolvem altitudes, como é o caso das linhas de costa, que são relacionadas com o nível do mar. A técnica proposta nessa tese gera o modelo de elevação digital da praia, com base em perfis de praia, no mesmo referencial de nível das marés e nele identifica a linha de costa. Para isso, os referenciais verticais de maré e do GPS são correlacionados através de um artifício apropriado que requer o conhecimento das alturas de maré e do GPS em um mesmo local. Os perfis de praia aqui referidos são constituídos de pontos coordenados gerados pelo deslocamento de uma antena GPS em ziguezague ao longo da praia. Essa metodologia mostrou-se adequada para localizar e monitorar linhas de costa com precisão sub-métrica e tem como principal vantagem o fato desse modelo facilitar a visualização do comportamento da linha d´água, sendo apropriado para simular o deslocamento do mar sobre o continente. Os resultados mostram a localização geográfica das linhas de costa das praias objeto desse estudo, expressas no Sistema de Projeção Cartográfica Universal Transverso de Mercator (UTM). O monitoramento da linha de costa provém da comparação do seu traçado, superpondo-se os modelos produzidos em diferentes épocas e indica comportamento sazonal das linhas de costas tanto nas praias de Japaratinga (máximo de 6,0 m), como na praia de Sauaçui (máximo de 8,0 m). Além disso, como o referencial do GPS tem grande estabilidade, ele pode ser usado no monitoramento da estabilidade dos marcos de apoio, cujas coordenadas são suscetíveis de alterações, em havendo subsidências do solo e/ou movimentações de placas da crosta terrestre

Full textAbstract:
Olika exemplar av common railinsprutare har testats i avseende på fördelning av bränsle över insprutarens åtta hål. Mätutrustning har konstruerats för att samla upp varje bränslestråle var för sig i varsitt provrör som sedan vägts. En stor del av arbetet bestod av konstruktion av mätutrustningen och anpassningar för att kunna utföra mätningarna så noggrant som möjligt. Tre olika insprutare av samma modell och en insprutare av senare modell testades för två olika driftspunkter och resultatet jämfördes med tidigare uppmätta värden för rökemissioner. Ytterligare sex insprutare testades för en driftspunkt. Samtliga insprutare visade upp hål till hålvariationer i olika stor utsträckning. Sammantaget av alla tio testade insprutare så kan enbart hål till hålvariationerna inte förklara skillnaderna i rök.Different examples of common rail injectors have been tested, referring to fuel distribution over the injector’s eight nozzle holes. Measurement equipment has been constructed to collect each fuel spray separately in one test tube each, which then will be weighed. A big part of the work has been constructing the measurement equipment and adjustments to be able to do the measurements as accurate as possible. Three different injectors of the same model and one injector of a later model were tested at two different load points and the results were compared with earlier measured smoke emissions. Another six injectors were tested at one load point. All the tested injectors showed hole to hole variations of different size. Summarizing the test results for the ten injectors, hole to hole variations can not alone explain differences in smoke production.

Full textAbstract:
The diploma thesis is focused on the description of the properties of humid air, its evaporation and its chemical composition. Calculation of the amount of evaporated water from the water surface or condensate evaporation during the drying process using domestic appliances, for rooms with permanent humidity and wet operation. In the theoretical part I will deal specifically with the methods of calculation of the evaporation and the properties of the inner microclimate depending on the external conditions with its influence on the building structures and the persons who will be present in such a microclimate. A solution of the air-conditioning unit is taken from the bachelor's thesis and three other variants of air-conditioning units are designed, which are compared in the framework of the optimal and economical solution for operation in the pool environment. The experimental part is focused on specific examples of calculation and measurement. The measurement deals with year-round moisture measurements in damp rooms in family buildings, specifically in bathrooms. Another part of the experimental measurement will be the determination of the amount of evaporated water from a domestic appliance designed to dry the laundry in a condensing manner. And the main, fundamental measurement is the amount of evaporated water on a particular model of the pool hall.

Full textAbstract:
Les interactions intermoléculaires jouent un rôle important dans de nombreux processus tant dans le domaine de la physique que de la chimie. L'étude des systèmes de petite taille liés par ces interactions (complexes moléculaires) permet d'avoir des informations très précises à partir desquelles il est possible d'aller plus avant dans la compréhension des processus qui résultent des ces interactions (prédissociation, changement de structure des entités du complexe). Pour étudier expérimentalement les complexes moléculaires de petite taille, nous avons élaboré un dispositif combinant un jet moléculaire pulsé à fente et une diode laser accordable dans l'infrarouge. Ce dispositif nous a permis d'observer les spectres d'absorption infrarouges de complexes à basse température (10 K) et à haute résolution (5.10-3 cm-1) avec une grande sensibilité grâce au système de détection synchrone hétérodyne que nous utilisons. Nous avons observé les spectres du mode d'élongation H-Cl des complexes C2H2-HCl et C2H4-HCl. Les résultats expérimentaux que nous ont fournis l'analyse spectroscopique rovibrationnelle des ces vibrations intramoléculaires ont permis de remonter à des informations sur les interactions mises en jeu dans ces complexes (influence de l'excitation vibrationnelle sur l'interaction, estimation de l'énergie de liaison à partir d'un modèle pseudo-diatomique). Afin d'avoir une vision plus globale des systèmes étudiés, nous avons complétés notre étude expérimentale par des études de chimie quantique. Nous avons notament dépassé les approximations usuelles des calculs ab initio par un calcul du potentiel intermoléculaire sur une grille à deux dimensions. Nous avons ainsi pu obtenir des informations sur les effets d'anharmonicité, de la correction de l'erruer de superposition de base et de couplages entre les mouvements intramoléculaires et intermoléculaires.

O gênero Genlisea forma parte da maior família de plantas carnívoras, as Lentibulariaceae. Das aproximadamente 30 espécies conhecidas do gênero, 17 encontram-se no Brasil e delas 10 são endêmicas. O gênero tem sido pouco estudado, sendo ainda escassos os estudos sobre aspectos genéticos e praticamente se desconhecem seu estado de conservação ou a fragilidade das populações naturais. Genlisea violacea A.St.-Hil. e G. aurea A.St.-Hil. são endêmicas e estão distribuídas nas formações de Cerrado e de Mata Atlântica, que são biomas muito frágeis. Neste trabalho foram estudadas a biologia reprodutiva e a polinização de G. violacea em duas populações naturais. Além disso, foram analisadas a estrutura genética e a dinâmica de populações de G. violacea e G. aurea. Para isso se desenvolveram microssatélites a partir de dados genômicos de G. aurea, transferíveis nas espécies congenéricas, incluindo G. violacea. Adicionalmente foi estudada a estrutura genética de algumas populações de G. violacea e G. aurea. Segundo as observações e análises realizadas, G. violacea é espécie alógama e autocompatível que oferece néctar aos visitantes, facilitando a autopolinização durante a antese e polinização cruzada durante todo o tempo de vida da flor, por meio de pelo menos duas espécies de abelhas. Mesmo assim, existem diferencias fenotípicas entre populações e incluso apresenta vario morfotipos dentro da mesma população. Ademais, foram desenvolvidos 12 marcadores microssatélites em G. aurea, que são transferíveis a espécies congenéricas. Nas populações das espécies estudadas observou-se variabilidade baixa e média, respectivamente para G. violacea e G. aurea, com maior variação dentro que entre populações, que refletem o sistema reprodutivo misto e uma polinização entomofílica. No caso de G. aurea, na estruturação genética se observou uma separação entre as populações da Bahia e do sul e centro oeste do país. As diversidades genéticas baixas destas duas espécies sugerem que devem ser vigiadas e protegidas para sua conservação.
The Genlisea genus is part of the larger family of carnivorous plants, Lentibulariaceae. They are approximately 30 known species of the genus, 17 in Brazil and 10 of them are endemic. The genus has been understudied, yet there are few studies on genetic aspects and practically its conservation status and the fragility of the natural populations are unknown. Genlisea violacea A.St.Hil. and G. aurea A.St.Hil. are endemic and are distributed in the formations of the Cerrado and Atlantic Forest, which are very fragile biomes. In this study we analyzed the reproductive biology and pollination of G. violacea in two natural populations. In addition, we also analyzed the genetic structure and dynamics of G. violacea and G. aurea populations. For this we developed microsatellite from genomic data of G. aurea, and did cross-amplification in congeneric species including G. violacea. According to the observations and analyses, G. violacea is self-compatible and allogamous that offers nectar to visitors, facilitating self-pollination during anthesis and cross-pollination throughout the flower lifetime through at least two species of bees. Also, there are differences between populations and phenotypic features included morphotypes within the same population. In addition, 12 microsatellite markers were developed in G. aurea, which are transferable to congeneric species. The populations of both species have low variability and average, respectively for G. violacea and G. aurea, with high variation within than among populations, reflecting the mixed reproductive system and pollination by insects. In G. aurea was observed in genetic structure a separation between the populations from Bahia and the South and Center-West of the country. The low diversity of these two species is indicative of the importance of monitoring and protecting the natural populations.

A espécie vegetal Lafoensia pacari A. St.-Hil., família Lythraceae, é uma planta medicinal muito utilizada nos estados de Goiás, Mato Grosso e Mato Grosso do Sul, sendo popularmente conhecida como pacari ou mangaba-brava. Dentre os vários propósitos medicinais desta planta, encontra-se o uso popular ?contra o desânimo?. Portanto, o nosso objetivo foi realizar o estudo fitoquímico do extrato bruto e frações obtidas biomonitorados pela atividade tipo antidepressiva. A análise fitoquímica apontou a presença de saponinas, taninos, esteroides, triterpenos e traços de flavonoides no extrato etanólico das cascas do caule de L. pacari (EEP) e na fração clorofórmica (FClor), a que melhor mimetizou o efeito do extrato bruto, são encontrados principalmente esteroides e triterpenos. Análises de RMN 13C, HMQC e CLAE-DAD da fração clorofórmica, permitiram identificar o esteroide ß-sitosterol e o triterpeno lupeol entre os principais constituintes desta fração. O pré-tratamento com EEP (100, 300 e 1000 mg/kg, v.o.) no teste do nado forçado (NF) sugere um efeito do tipo antidepressivo sem alteração na deambulação no campo aberto (CA). Após o fracionamento, a FClor foi a que melhor reteve a atividade biológica do extrato, sendo a dose de 70 mg/kg a mais efetiva no NF e no teste de suspensão pela cauda. Tanto o pré-tratamento com PCPA (100 mg/kg i.p., durante 4 dias ? inibidor da síntese de serotonina), quanto AMPT (100 mg/kg i.p., 4 h antes ? inibidor da síntese de catecolaminas) bloqueou o efeito da FClor, sugerindo o envolvimento do sistema serotoninérgico e catecolaminérgico na atividade observada. Dentre os compostos isolados, apenas o lupeol (40 mg/kg, v.o.) reduziu o tempo de imobilidade no NF sem alterar a deambulação dos animais no CA e as drogas PCPA e AMPT também bloquearam a atividade deste composto. Ao avaliar a atividade das isoformas MAO-A e MAO-B, na presença de FClor e de lupeol, não foi detectada qualquer inibição enzimática. Quanto à capacidade de aumentar o nível hipocampal do fator neurotrófico derivado do cérebro (BDNF), apenas a FClor se mostrou ativa no protocolo de tratamento estudado. Neste estudo não foi observado aumento na expressão (Western blotting) das proteínas CREB e pCREB, após os tratamentos com a FClor (70 mg/kg), o lupeol (40 mg/kg), o ß-sitosterol (40 mg/kg) e a imipramina (30 mg/kg). Assim, concluímos que o EEP, a fração rica em triterpenos e o triterpeno lupeol apresentaram efeito do tipo antidepressivo envolvendo as monoaminas endógenas, sem inibir diretamente a enzima MAO. Além disso, a FClor aumentou o nível hipocampal de BDNF, sem a participação da via de sinalização mediadapor CREB. Portanto, a L. pacari é uma espécie vegetal promissora na avaliação de fitoconstituintes com atividade antidepressiva.
Abstract : The species Lafoensia pacari A. St.-Hil., Lythraceae Family, is a medicinal plant widely used in the states of Goiás, Mato Grosso and Mato Grosso do Sul, popularly known as ?pacari? or ?mangaba-brava?. Among the ethnophamalogycal uses was the use ?to raise the spirits?. Thus, in the present, our aim was to perform the phytochemical study of the crude extract and fractions bio-guided by the antidepressant-like activity. Phytochemical analysis showed the presence of saponins, tannins, steroids, triterpenes and flavonoids traces on the ethanol extract of of L. pacari stem bark (EEP) and in the chloroform fraction (FClor), the one that better mimicked the crude extract effects, are mostly found steroids and triterpenes. 13C NMR, HMQC and HPLC-DAD analysis of chloroform fraction have identified the steroid ß-sitosterol and the triterpene lupeol among the main constituents of this fraction. Pretreatment with EEP (100, 300 and 1000 mg/kg, p.o.) before the forced swimming test (NF) suggests an antidepressant-like effect with no change in ambulation in the open field (CA). After fractionation, the FClor was the one that best retained the biological activity of the crude extract and the dose of 70 mg/kg was the most effective in the NF and the tail suspension test. Pretreatment with PCPA (100 mg/kg i.p. for 4 days - a serotonin synthesis inhibitor) as well as AMPT (100 mg/kg i.p. 4 hours prior - a catecholamine synthesis inhibitor) blocked the FClor effect, suggesting the involvement of catecholaminergic and serotonergic system in the observed activity. Among the compounds isolated, only lupeol (40 mg/kg, p.o.) reduced the immobility time in the NF without changing the animal?s activity in CA. PCPA and AMPT also blocked the lupeol activity. In MAO-A and MAO-B isoforms activity assay in the presence of FClor and lupeol, no enzyme inhibition was detected. Regarding the ability to increase the hippocampal level of brain-derived neurotrophic factor (BDNF), only FClor was active in the studied treatment protocol. No increases were seen in CREB and pCREB proteins expression (Western blotting) after treatment with FClor (70 mg/kg), lupeol (40 mg/kg), ß-sitosterol (40 mg/kg) and imipramine (30 mg/kg). We have concluded that the EEP, the triterpenes fraction and lupeol showed an antidepressant-like effect involving endogenous monoamines, without directly inhibiting the MAO enzyme activity. Furthermore, FClor increased hippocampal BDNF levels, without involving of the signaling CREB-mediated pathway. Therefore, L. pacari is a promising plant in the study of phytochemicals with antidepressant activity.

Wang, Ke. "Investigation of total HDL and HDL subclass kinetics using stable isotope techniques in healthy subjects." Thesis, University of Surrey, 2015. http://epubs.surrey.ac.uk/807836/.
Full textAbstract:
Background: HDLs are heterogeneous particles, and apoA-I is the major apolipoprotein in human HDL. CVD is a multifactorial condition, and a various lipids and lipoproteins in the plasma are involved in the development of CVD. It has been suggested that HDLs have an inverse association with the risk of CVD. A high sugar intake (especially fructose and sucrose) was found to associate with a low HDL-C level and increased risk of CVD. However, the effect of dietary sugar on HDL kinetics is unclear. An insight of HDL subclass kinetics may provide a better understanding of the whole dynamic of HDL metabolism. Methods: Two studies were undertaken: 1) A controlled, randomized crossover dietary intervention study was carried out in 6 overweight middle-aged men. Subjects underwent two 12-week dietary interventions with high and low non-milk extrinsic sugar diets. Total HDL kinetics was measured using a primed constant intravenous infusion of [1-13C] leucine for 10 hours. 2) A HDL subclass kinetic study was carried out in 6 healthy subjects (3 males and 3 females). An intravenous bolus injection of [1-13C] leucine was applied to measure HDL subclass kinetics. Blood samples were taken during a 10-hour study and the following 2 weeks. Total HDL, HDL2 and HDL3 were separated from the plasma by ultracentrifugation, and αHDL and preβHDL were isolated by agarose gel electrophoresis. ApoA-I in HDL fractions was separated by SDS-PAGE. After purification, hydrolysis and derivatization, the isotopic enrichment of apoA-I in HDL was measured by GC-MS and apoA-I fractional catabolic rate (FCR) and production rate (PR) was calculated for each subclass and total HDL. Results: In the dietary intervention study, the FCR of total HDL apoA-I on the high and low sugar diet (0.20 ± 0.02 and 0.18 ± 0.02 pools/day) was similar, as was the PR (7.33 ± 0.66 and 6.05 ± 0.72 mg/kg/day respectively). In the HDL subclass study, the concentration of αHDL apoA-I (0.97 ± 0.05 g/L) was significantly higher than that of preβHDL apoA-I (0.15 ± 0.03 g/L) (p<0.001). The FCR of αHDL and preβHDL apoA-I was 0.10 ± 0.02 and 0.13 ± 0.04 pools/day, and the PR of αHDL and preβHDL apoA-I was 3.94 ± 0.73 and 0.67 ± 0.12 mg/kg/day respectively. The concentration of HDL3 apoA-I (0.68 ± 0.04 g/L) was significantly higher than that of HDL2 apoA-I (0.23 ± 0.06 g/L) (p=0.002). The FCR of HDL2 and HDL3 apoA-I was 0.15 ± 0.02 pools/day for both, and PR of HDL2 and HDL3 apoA-I was 1.35 ± 0.35 2 and 3.81 ± 0.51 mg/kg/day respectively. A significant difference was observed between αHDL and preβHDL apoA-I PR (p=0.010), and between HDL2 and HDL3 apoA-I PR (p=0.030) in the whole group. The concentration of HDL2 apoA-I was higher in women (0.32 ± 0.08 g/L) than men (0.13 ± 0.02 g/L) though the difference was not significant. HDL2 apoA-I PR was significantly higher in women than men (p=0.017). Conclusion: The high and low sugar diet did not affect HDL metabolism in overweight men. The higher apoA-I concentration of αHDL and HDL3 might be due to the higher apoA-I PR of αHDL and HDL3 compared to preβHDL and HDL2 respectively in healthy subjects. The higher level of HDL2 apoA-I in female than male subjects might be due to the higher PR of HDL2 apoA-I in women.

Full textAbstract:
Today’s electronics in aviation (avionics) are more complex than ever before. With higher requirements on safety and reliability and with new SoC (System on Chip) technology, the validation and verification of designs meet new challenges. In commercial and military aircraft there are many safety-critical systems that need to be reliable. The consequences of a failure of a safety-critical system onboard a civil or military aircraft are immeasurably more serious than a glitch or a bit-flip in a consumer appliance or Internet service delivery. If possible hazards are found early in the design process, a lot of work can be saved later on. Certain structures in the code are prone to produce glitchy logic and timing problems and should be avoided. This thesis will strengthen Saab Avitronics knowledge of adaptable rule checking tools for HDL, with a market analysis of the tools available. Moreover will it evaluate two of the most suitable tools and finally it will describe some of the design issues that exist when coding safety-critical systems. Finally it is concluded that the introduction of static rule checking tools will help the validator to find dangerous constructs in the code. However, it will not be possible to fully automate rule checking for safety-critical systems, because of the high requirements on reliability.

Os hidróxidos duplos lamelares (HDLs) são materiais que podem ser utilizados para modificar ou incorporar características a polímeros termoplásticos ou termorrígidos. O presente trabalho tem como objetivo a síntese e caracterização de HDLs de Mg-Al intercalados com os íons glicinato, alaninato e dodecil sulfato e a sua utilização na formulação de nanocompósitos bicomponente HDL/epóxi, com diferentes teores de HDL, produzidos por casting e de compósitos tricomponente HDL/epóxi/fibra de vidro moldados por RTM. Os HDLs foram sintetizados pelo método da coprecipitação e incorporados a epóxi com o auxílio de solventes e de ultrassom. Para tal, foram avaliados os solventes acetona, clorofórmio e DMF, sendo o DMF selecionado como o melhor agente de dispersão. Os compósitos e nanocompósitos obtidos foram caracterizados quanto à dispersão dos HDL na matriz, às suas propriedades de resistência à chama (teste horizontal e vertical), à estabilidade térmica, às propriedades mecânicas e dinâmico-mecânicas. A incorporação dos HDLs provocou um incremento na estabilidade térmica dos compósitos e todas as amostras com esta carga apresentaram comportamento autoextinguível no teste de queima vertical, além de apresentarem uma grande diminuição na taxa de queima em comparação ao epóxi puro. A utilização dos HDL não possibilitou melhora nas propriedades mecânicas e dinâmico-mecânicas dos compósitos, que só foi obtida com a utilização do reforço de fibra de vidro.Layered double hydroxides (LDHs) can be used to modify or incorporate characteristics into a variety of thermoplastic or thermoset polymers. The present work aims to synthesize and characterize Mg:Al LDHs intercalated with glycinate, alaninate and dodecyl sulfate and to use them in the formulation of bi-component LDH/epoxy nanocomposites, with distinct LDH content, obtained by casting, and tricomponent LDH/epoxy/glass fiber composites molded by RTM. The LDH was synthesized, using the coprecipitation method, and incorporated into epoxy with the aid of solvents and ultrasonication. For that, acetone, chloroform and DMF solvents were evaluated, and DMF yielded the best performance as dispersing agent. The obtained composites and nanocomposites were evaluated regarding the quality of the LDH dispersion in the matrix, their flame resistance characteristics (horizontal and vertical testing), thermal stability, mechanical and dynamic-mechanical properties. The incorporation of LDH caused an increase in thermal stability of the composites and all samples containing LDH showed self-extinguishing behavior in the vertical burning test, and a large decrease in the burning rate was found compared to neat epoxy. The use of LDH did not significantly alter the mechanical and dynamic-mechanical properties of the composites, which was only achieved by using a glass fiber reinforcement.

Les taux de cholestérol-HDL (C-HDL) représentent un facteur de risque indépendant de maladie cardiovasculaire et des taux élèves de C-HDL sont corrélés à une diminution du risque cardiovasculaire. Dans le contexte du transport inverse du cholestérol, la sortie du cholestérol des cellules et la délivrance des esters de cholestérol au niveau hépatique représentent les étapes majeures impliquant les particules HDL. Au cours des dyslipidémies athérogènes les concentrations plasmatiques de C-HDL ainsi que la distribution du cholestérol au sein des sous populations de HDL sont altérés. La protéine clé impliquée dans le remodelage des HDL et le transport inverse du cholestérol est la protéine de transfert des esters de cholestérol (CETP). Ainsi l’inhibition de l’activité de la CETP pourrait corriger le profile lipidique anormal des dyslipidémies athérogènes associées à un phénotype C-HDL bas. Nous avons démontré que chez les sujets normolipidémiques les taux plasmatiques de C-HDL ne reflètent pas l’efficacité de l’étape initiale de la voie du transport inverse du cholestérol et que cette étape est sujette à des contraintes spécifiques liées au genre. De plus, nous avons démontré que chez de patients présentant une dyslipidémie de Type IIB associée à un phénotype C-HDL bas, l’inhibition de la CETP module différemment les fonctions biologiques des sous fractions HDL et restaure ainsi les étapes altérées de la voie du transport inverse du cholestérol.

Thesis (MA)--Stellenbosch University, 2002.ENGLISH ABSTRACT: The aim of this study was to explore gay men's relationship with their parents before and after the revelation of their sexual orientation towards their parent(s). Six men, who voluntarily offered to participate in the study, were interviewed by means of a semi-structured interview. These interviews were initially tape recorded and there after transcribed by the researcher. To be included in the study the participants had to comply with the following criteria: i) they had to be male; ii) 18 years or older; iii) have revealed their sexual orientation towards one or both parents; vi) be English or Afrikaans speaking; v) reside within Paarl, Stellenbosch or Cape Town; and vi) accept that no remuneration would be received for participation in this research. The process by which data was analysed mainly included : The organisation of data, the generation of categories, themes and patterns, testing the emerging categories and patterns, seeking alternative explanations, and writing the final report. Findings from the research study include four main themes, with ten sub-themes identified. Firstly, the nature of the relationship between the mother and the gay son before disclosure of the sons' sexual orientation. The associated sub-themes were: i) Confirmation that the revelation was usually first made towards the mother or siblings, ii) the stadium of self-awareness and process of self-empowering of the son about his gay identity before disclosure towards the mother, iii) mentioning that the mother was aware of the sons' sexual preferences before disclosure, and iv) the relationship between mother and son and the supporting role that she plays within the parental context after disclosure. Secondly, the nature of the relationship between the father and the gay son before the revelation of the sons' sexual orientation. The associated sub-themes were: i) mention of a patriarchal system that existed within the parental relationship, which could be linked to the fathers' social perception, including, amongst others, homophobia, and ii) the father/son relationship after disclosure of the sons' sexual orientation. Thirdly, parental involvement regarding acceptance and support after disclosure of the sons' sexual orientation. The associated sub-themes are:i) the avoidance of the gay subject by the parents during communication within the family context, ii) the sensitivity and avoidance of discussions about lovers or companions within the family relationship, and iii) the regularity of contact between the parent(s) and their gay son after disclosure. Lastly, the nature of the relationship between the gay brother and his siblings before the revelation of his sexual orientation. The associated sub-theme were: i) the unconditional acceptance and support of the siblings. These themes are subsequently discussed in terms of existing research literature in this field of study.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die verhouding wat tussen gay mans en hul ouer(s) bestaan het voor en na openbaarmaking van die seun se seksuele orientasie aan die ouer(s), te verken. Ses mans wat vrywilliglik aangebied het tot deelname aan die ondersoek, is deur middel van 'n semi-gestruktureerde onderhoud ondervra. Hierdie onderhoude is eers op band geneem en daarna deur die navorser verbatim getranskribeer. Die riglyne vir insluiting tot die studie was dat die deelnemers aan die volgende kriteria moes voldoen: i) hulle moes manlik wees; ii) 18 jaar en ouer; iii) alreeds hul seksuele orientasie teenoor een of beide ouers bekend gemaak het; iv) Engels of Afrikaanssprekend; v) woonagtig in Paarl, Stellenbosch of Kaapstad; en vi) aanvaar het dat geen besoldiging vir deelname aan die navorsing ontvang sal word nie. Die proses van data-analise het hoofsaaklik ingesluit: Die organisering van data; die generering van kategoriee, temas en patrone; die toetsing van sigbaarwordende temas; soeke na alternatiewe verduidelikings en die skryf van die finale verslag. Bevindinge uit die navorsingstudie sluit in vier hooftemas met tien subtemas wat gei'dentifiseer is. Eerstens, die aard van die verhouding tussen moeder en gay seun voor die openbaarmaking van die seun se seksuele orientasie. Die geassosieerde subtemas was: i) die bevestiging dat die openbaarmaking meestal eerstens teenoor die moeder of sibbe sou geskied, (ii) die selfbewustheidstadium en die selfbemagtigingsproses van die seun ten opsigte van sy gay identiteit voor die openbaarmaking teenoor dikwels die moeder, (iii) die vermelding dat die moeder bewus was van die seun se seksuele orientasie reeds voor openbaarmaking, en (iv) die moeder-en-seun-verhouding en die ondersteunende rol wat sy binne ouerverband inneem na bekendwording van die seun se seksuele orientasie. Tweedens, die aard van die verhouding tussen vader en gay seun voor openbaarmaking van die seun se seksuele orientasie. Die geassosieerde subtemas was: (i) die vermelding van 'n patriargale sisteem wat binne gesinsverband bestaan het, en wat ook saamhang met die vader se sosiale persepsies wat onder andere homofobie insluit, en (ii) die vader-en-seun-verhouding na die bekendwording van die seun se seksuele orientasie. Derdens, ouerbetrokkenheid in terme van aanvaarding en ondersteuning na bekendwording van die seun se seksuele orientasie. Die subtemas wat hieruit gevloei het, was: (i) die kommunikatiewe vermyding van die gay onderwerp deur die ouer(s) binne gesinsverband, (ii) die sensitiwiteit en vermyding van gesprekke oor minnaars of metgeselle binne ouerverband, en (iii) die gereeldheid van kontak tussen ouer(s) en gay seun na bekendwording van die seun se seksuele orientasie. Laastens, die aard van die verhouding tussen gay broer en sibbe voor openbaarmaking van die broer se seksuele orientasie. Die geassosieerde subtema was: (i) die onvoorwaardelike aanvaarding en ondersteuning deur die sibbe. Die temas is vervolgens bespreek in terme van bestaande navorsingsliteratuur oor die onderwerp.

Research was performed during 2012 – 2013 year in LSMU Biological Systems and Genetic Research Institute of K. Janusauskas Animals Genetic Laboratory. Samples for DNA testing were collected from wild and domestic pigs. Fattening and meat quality data were obtained from the State of Pigs Control fattening Station of Kaunas Department. A total of 137 pigs (45 wild boars, 5 Vietnamese pigs, 12 Pecari, 25 Landrace, 25 Yorkshire and 25 Pietrian) were tested for halothane genotype. For the effect of HAL gene on meat and fattening properties, 45 crossbreeds (LxJxP) from State Pigs Breeding Station were selected. Plucked hair was used as a source of genomic DNA. All tested animals were characterized as normal homozygotes (NN), heterozygotes (Nn) or recessive homozygotes following amplification of a target region of the HAL gene using the polymerase chain reaction (PCR), followed by a restriction endonuclease assay. The resulting PCR was digested with the restriction enzyme Alw21I, followed by agarose gel electrophoresis. Results and conclusions. In 75 tested domestic pigs, 88 % were NN and 12 % were Nn genotype. In 62 tested wild pigs all animals were NN genotipe.

Med målet att undersöka huruvida Sveriges planer för biodrivmedeltillverkning är tillräckligt väl underbyggd har denna uppsats fokuserat på att undersöka vad biokol är, hur det produceras och vilka egenskaper det besitter. Biokol och biodrivmedel har därefter jämförts och analyserats ur hållbara dimensioner, så som ekologiska, sociala och ekonomiska, med tillägget att fungera som bistånd.Trots goda karaktärsdrag hos biodrivmedel och en hög självförsörjningsgrad i Sverige så pekar resultaten av denna uppsats mot att Sverige snarast bör tillsätta en offentlig utredning med fokus på biokol och att denna utredning undersöker om produktion kan ske i samverkan med biodrivmedel.Biokol har visat sig inneha en oerhörd potential som jordförbättrare och avfallshanterare, vilket gynnar biståndsidén. Det är dessutom synnerligen potent som en motkraft mot global uppvärmning till följd av ökande atmosfäriskt koldioxid och dess tillverkning bidrar dessutom med goda egenskaper vad gäller energieffektivitet och synergisamverkan med aktörer som kräver uppvärmning.With the aim to investigate whether Swedens plans for biofuel production is sufficiently substantiated, this paper has focused on researching what biochar is, how it is produced and what characteristics it possesses. Biochar and biofuel has then been compared and analysed from sustainable dimensions, such as ecological, social and economic, with the addition of the potential as aid.Despite the beneficial traits of biofuel, and a high level of self-sufficiency in Sweden, the results of this article points towards the recommendation that Sweden as soon as possible appoints an official investigation focusing on biochar, and that this investigation also concentrates on researching whether biochar can be produced in conjunction with biofuels.Biochar has proven to possess enormous potential as soil improvement and waste disposer, which benefits the idea of it working as foreign aid. It is also particularly potent as a counter to the rising levels of atmospheric carbon dioxide with it’s consequence of global warming. Its production contributes to great opportunities concerning energy efficiency and synergistic interaction with actors who requires a lot of heating.

Desarrolla el diseño de un procesador segmentado con la finalidad de ayudar a los estudiantes en el aprendizaje del desempeño de este tipo de procesadores, principalmente cuando se presentan conflictos con relación a la secuencia de instrucciones utilizadas y sus dependencias. Para ello se utilizan técnicas hardware, tales como el adelantamiento de datos, inserción de burbujas, y anticipación de riesgos. Estos métodos se aplican para la arquitectura MIPS que consta de una segmentación de 5 etapas y cumple con las características de la arquitectura ISA tipo RISC empleada ampliamente en la temática de “Arquitectura de Computadoras”. El método empleado es desarrollar cada vez una nueva versión del procesador adaptado para solucionar el nuevo paradigma mostrando la mejora en su desempeño luego de hacerlo, así tendremos una versión que muestra la solución por riesgos de dependencia de datos. Otra versión del procesador para el caso en que una instrucción dependa del dato de una instrucción de carga, para finalmente realizar una última versión que solucione las dependencias debido a las bifurcaciones, que vienen a ser las más características y que presenta dificultad de asimilar en esta parte de la temática, tanto por la poca afición a la lectura del estudiantado como a la baja comprensión lectora que se tiene. El proceso de ver los eventos y simularlos más que solo verlos estáticamente permitirá una mejor y rápida comprensión de estos fenómenos así como su interacción al modificar los programas y el hardware del procesador respectivo.

Full textAbstract:
Contrairement aux HDL de sujets sains, les HDL de patients diabétiques ont perdu leur capacité à contrecarrer les effets inhibiteurs des LDL oxydées sur la vasorelaxation endothélium dépendante. Les mécanismes en cause ne sont pas connus. Or la glycation et l’oxydation sont deux phénomènes majeurs au cours du diabète. Nous avons donc étudié in vitro, le rôle de la glycation (associée ou non à une oxydation spontanée), et de l’oxydation d’HDL issues de sujets sains, sur leurs capacités à contrecarrer les effets inhibiteurs des LDL oxydées sur la vasorelaxation endothélium dépendante. Chaque condition a conduit au même constat: les HDL modifiées perdent leur pouvoir vasorelaxant en présence de LDL oxydées. En revanche, en l’absence de LDL oxydées, elles n’altèrent pas la vasorelaxation induite par l’acétylcholine. Ainsi les modifications structurelles des HDL (glycation, oxydation, ou les deux) induisent une perte de leur capacité à protéger l’endothélium du stress oxydatif, plutôt qu’un effet délétère direct sur l’endothélium. Un des mécanismes majeur impliqué dans ce phénomène est probablement l’absence de fixation de ces HDL modifiées à leur récepteur SR-BI. Elles ne pourraient plus alors s’opposer au niveau des cavéoles aux effets délétères des LDL oxydées, et ne favoriseraient plus la production de NO. Mais si aussi bien la glycation que l’oxydation des HDL entraînent ces effets néfastes, il semblerait qu’en condition physiopathologique (oxydation spontanée des HDL glyquées), l’oxydation ne majore pas cette perte de capacité des HDL à contrecarrer les effets inhibiteurs des LDL oxydées sur la vasorelaxationContrary to HDL from normolipidaemic and normoglycaemic subjects, HDL from diabetic patients have lost their capacity to reverse the inhibition of vasorelaxation induced by oxidized LDL. Mechanisms involved are unknown. The glycation and oxidation of HDL are two major phenomena in diabetes mellitus. The aim of this work was to study in vitro the role of glycation (with or without spontaneous oxidation) and oxidation of HDL, on their capacity to counteract the inhibitory effect of oxidized LDL on endothelium-dependent vasorelaxation. Each state showed the same result, modified HDL lost their vasorelaxing power in stress conditions (with oxidized LDL). Nevertheless, modified HDL alone (without oxidized LDL) did not alter vasorelaxation induced by acetylcholine, after noradrenaline-induced vasoconstriction. Thus, modifications of HDL induce a loss of the ability to protect vessels from oxidative stress rather than have a direct deleterious effect on the vessel. One of the major mechanisms involved in this phenomenon is probably the loss of SR-BI binding of these modified HDL, that could lead to the inability of HDL to protect caveolae from deleterious effects induced by oxidized LDL and could not preserve NO production. However, though glycation, like oxidation of HDL, leads to these deleterious effects, it would seem that during physiopathological conditions, with the spontaneous oxidation of glycated HDL, oxidation does not aggravate the loss of the capacity of diabetic HDL to counteract the inhibitory effect of oxidized LDL on endothelium-dependent vasorelaxation

Utgångspunkten för undersökningen som presenteras i den här uppsatsen är Bengt Sigurds studie av textbindning i elevtext, Tre experiment med text: Att presentera Buffalo Bill (1977). Syftet med den här uppsatsen är att undersöka textbindning i elevtexter, skrivna utifrån samma uppgift (Sigurd 1977) för att se hur eleverna löser textbindningen i en satsatomuppgift. En satsatom är minsta möjliga informationsbärande sats, t.ex. Flickan går och Bollen är rund. Elever från ett yrkesförberedande och ett studieinriktat program fick en satsatomuppgift om westernhjälten Buffalo Bill. Uppgiften innebar att de skulle skriva en sammanhängande och välformulerad text utifrån givna 24 satsatomer. Totalt åtta uppsatser, fyra från varje klass, har undersökts med fokus på textbindning, innehåll och sammanhang.
Studien visar att de båda klasserna uppfattar instruktionerna på olika sätt och detta får konsekvenser för innehållet och de textbindningar som undersöks. Framför allt visar sig detta när det gäller referensbindningarna. Den yrkesförberedande klassen, har lagt till informationsbärande satser i sina texter, och får därför fler delidentiteter och associativa bindningar än den studieförberedande klassen som inte har lagt till någon egen information i sina texter. Vad gäller konnektiva bindningar så har den yrkesförberedande klassen fler antal konnektiver och konnektiverna är karaktäristiska för en berättande text. I tre av åtta elevtexter förekommer brister i textbindningen, t.ex. felaktigt val av konnektiver och syftningsfel inom ledfamiljerna. Dessa brister i textbindningen stör sammanhanget i texten och därmed läsförståelsen.

Full textAbstract:
In this master’s thesis, a validation method for engine models in a HIL simulator is developed. To make the validation automatic, a script has been written in the programming language Python that executes the engine model in the same way as the real engine in a test cell at Scania CV. Variables in the model are recorded in real-time and compared to recordings from the engine test cell. The validation method handles static as well as dynamic engine model validation. The submodels in the current engine model that causes the most deviation from engine test cell data are identified. One of them, i.e. the turbine model, is improved by creating a semi-physical model of a Variable Geometry Turbine (VGT). Furthermore, future improvements have been suggested.
