Denne masteroppgaven omhandler praktiske forsøk utført for å dokumentere forankringskapasiteten til trådbindere fra horisontale mørtelfuger. Eksisterende konstruktive løsninger for forankring av skallmurvegger og forblendinger tar utgangspunkt i overføring av vindlaster. Etter innføring av Eurokode 8 i 2010, er det nå krav til å dimensjonere konstruksjoner for seismiske påvirkninger. Det har derfor vært av økende interesse å kartlegge dagens forankringsløsninger nærmere. Det ble utført 72 uttrekksforsøk i henhold til NS-EN 846-5, der de mest anvendte forankringsløsningene i Norge ble testet. Innvirkningen ulike parametere har på uttrekkskapasiteten ble testet i egne delserier av mindre skala. Resultatene fra uttrekksforsøkene ble sammenliknet med en doktorgradsavhandling utført av Hamed (2011) og en masteroppgave utført av Bruaset (2011). Begge oppgavene konkluderte med at trådbindere må ha en dimensjonerende uttrekkskapasitet fra mørtelfuger på minimum 2,0 kN for å ha tilstrekkelig forankringskapasitet i ulykkestilstand.Forsøkene viste at forankringssystem som er murt opp med mørtelklasse M5 og en 4 mm tykk L-binder er tilstrekkelig dimensjonert for ulykkestilstand Prøvestykkene som var murt opp med høyere mørtelfasthet hadde ikke tilstrekkelig kapasitet, da heftfastheten ikke var tilfredsstillende.Rapporten omhandler i tillegg numeriske modeller som ble utarbeidet i DIANA. Dette med hensikt for å kunne simulere forsøkene som ble utført i laboratorium.

Tsiotsios, Chourmouzios. "Shape estimation in murky water using photometric stereo." Thesis, Imperial College London, 2015. http://hdl.handle.net/10044/1/57033.
Full textAbstract:
Photometric stereo offers the possibility of object shape reconstruction via reasoning about the amount of light reflected from oriented surfaces. However, in murky media such as sea water light interacts not only with the scene but also with the medium particles. The resulting image formation model is complex and hard to optimize directly for scene orientation and albedo. The effectiveness of previous solutions has been limited since they were based on unrealistic assumptions about the imaging conditions or on external hardware for estimating some of the unknown model variables. In this thesis we propose a complete Photometric Stereo framework that yields useful reconstructions within a wide range of conditions in murky water. First, we show how the problem can be simplified by taking account of the additive light component that is backscatterd by the particles. A backscatter compensation method is proposed, based on the observation that the respective light signal varies smoothly across the sensor according to the pixel position with respect to the light source but is scene-depth independent. This makes its approximation experimentally appropriate using only the captured images and results in shape reconstruction similar to that in clean water. Second, we propose an uncalibrated method for solving Photometric Stereo in the presence of near-field illumination within murky water. In this case, the incident illumination on the scene is non-uniform as it varies according to the scene depth and the attenuation coefficient of the medium. We propose an algorithm for optimizing the resulting complex system of equations without resorting to external equipment or calibration. Finally, we design a novel Photometric Stereo system with dynamic lighting that can predict the validity of different photometric models in uncontrolled imaging conditions. Both our and previous approaches have been based on simplifications of the original-complex image formation in murky water. The effectiveness of such simplified models differs according to the imaging conditions and it can not be easily estimated as both the scene and the environment are usually unknown. Our proposed system can predict the validity of such photometric models, based on the observation that the change in estimated surface normals as the light sources position is varied with respect to the camera is a direct estimate of a model's effectiveness. In this way, the system can approximate the true reconstruction error and adapt automatically some critical factors in order to maximize the reconstruction quality, such as the camera-scene distance, the light sources position and the photometric model. Our work is evaluated through extended numerical simulations and real experiments in a water tank and real port water, and yields detailed reconstructions over a wide range of distances and underwater visibilities.

Full textAbstract:
This thesis contributes a rich empirical analysis of urban water governance in Delhi, with particular attention to informality, groundwater and reforms. My research aims to develop understanding of the relationships between reforms, under both private sector management and a new progressive government, and existing informal water arrangements, particularly groundwater use, which households rely on in the absence of adequate public sector supply. I draw on interviews with 150 residents, as well as water suppliers, project officials, government staff, politicians and party workers over 18 months of multi-sited research in South Delhi’s unauthorised colonies and urban villages. I use the idea of ‘informal infrastructures’ or ‘infrastructural informality’ connects my empirical research across different sites and scales. Bringing ideas from the literature on informality and infrastructures together under this framing offers modifications to the ways that ‘informality’ and ‘infrastructures’ are often understood and used. I use informality in this way ‘as a method’ to focus on the contingently enacted, materially and socially constituted character of various infrastructure processes. I analyse the informal governance and politics of water supply at three difference sites and scales. Within Delhi’s government network at an all-city level I note the formally and informally differentiated nature of the network and the challenges of knowledge and control of it. Outside of the piped network, I examine the decentralised infrastructures of tubewells and water tankers, primarily in the South Delhi areas of Sangam Vihar and Deoli. These decentralised supply modes are socially embedded in systems of party politics, caste and land-ownership with a range of opportunities for discretion, patronage and misallocation. They illustrate the connection and contrasts between informality in different resources, such as land and water, and infrastructures. I then examine an additional layer of urban water governance, in a Public Private Partnership (PPP) for urban water reform, in a zone around the Malviya Nagar area, also in South Delhi. I argue that the complexity of India’s urban social hydrology, even in wealthy areas, has been underestimated by this initiative, and that despite an evolution of the PPP model concerns over the project’s equity and viability remain. The high level of informality across different infrastructural systems in my research sites suggests the coexistence of a submerged ‘technopolitics’ operating through bureaucratic and technical modes of governance, with both overt and covert uses of intercession, personalisation and force. The study makes contributions to knowledge in the following areas: informal urban water supply in India, particularly in unauthorised colonies and urban villages, in a region of high groundwater use, its relationship to water supply reforms from both government and a multinational public-private partnership.

Full textAbstract:
Thesis submitted to Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa in partial fulfilment of the requirements for the degree of Master in Computer ScienceThis dissertation focuses on the composition of requirements artefacts using Aspect-Oriented Requirements Engineering (AORE), to develop an enhanced composition mechanism to extend the work previously done to the Aspect-Oriented Requirements Analysis (AORA) approach (Brito and Moreira, 2006; Brito et al., 2007). The AORA approach consists of the identification, modularization, composition and management of crosscutting concerns. However, the AORA composition (Soeiro et al., 2005) is poor, handles composite elements as a “black box” and operates at a coarse-granularity level with reduced number of operators, resulting in limited composition expressiveness. These limitations have a negative impact when moving towards later stages of software development, such as software architecture and design phases. The core of the work of this Master dissertation is the development of: •a composition language that enables a multi-dimensional specification at the requirements level; •an approach that enables the composition of requirements’ artefacts based on Objectives, therefore stating the purpose or the goal of the composition. The output is an approach that provides a composition process supported by a well-defined syntax and semantics, as well as tool support integrated into the AORA tool (Soeiro et al., 2005; Brito et al., 2006). The approach, together with the composition language, were applied to a real case study, from the SOFTAS project, in the air traffic control domain, which is operated by Navegação Aérea de Portugal (NAV), the company that controls the Portuguese air space.

Full textAbstract:
Animals experience variation in their environment because of natural changes. However, due to anthropogenic disturbance, the speed and severity of these changes have recently increased. This thesis investigates how reproductive behaviours may be affected by human induced environmental change. In specific, I investigate how visual and chemical changes in the aquatic environment, caused by eutrophication, affect mating systems and sexual selection in fish. Broad-nosed- and straight-nosed pipefish, which both have been studied in detail for a long period, were used as model organisms. These two species are particularly suitable model organisms since they perform complex courtship behaviours, including the advertisement of ornaments and a nuptial dance. Further, two distinct populations were studied, one on the Swedish west coast and one in the Baltic Sea, as these two locations vary in the degree and extent of environmental disturbance, in particular turbidity. I found that changes in the visual environment had no impact on the development of female sexual ornaments in these sex-role reversed pipefishes, but it hampered adaptive mate choice. Turbidity also had a negative effect on reproductive success in the Baltic Sea population. Changes in the chemical environment in the form of increased pH reduced the probability to mate, while hypoxia did not alter mating propensity. However, hypoxic water delayed the onset of both courting and mating. Hence, human induced change in aquatic environments may alter the processes of sexual selection and population dynamics.

Full textAbstract:
Environmental sociology and the sociology of scientific knowledge provide a strong theoretical foundation for investigating the role of science in environmental disputes. The field of environmental dispute resolution has built a body of literature, outlining the techniques and practices that underpin the successful resolution of disputes, over controversial environmental issues. However, the literature on dispute resolution has generally neglected the role of science in environmental disputes. This thesis develops a theoretical framework based on concepts from environmental sociology and the sociology of scientific knowledge in order to critically examine the role of science in environmental disputes. In particular, this thesis combines the theory on claims-making from environmental sociology with actor-network theory and the theory on boundary-work from the sociology of scientific knowledge, to analyse the way in which science was involved in the dispute over phasing out extractive dredging from the Brisbane River. Data were collected from qualitative in-depth interviews with key players in the Brisbane River dredging dispute and combined with analysis of relevant documents and newspaper articles. Each of the components of the theoretical framework developed in this thesis contributes to an in-depth analysis of the way in which science was involved in the dredging dispute. The environmental claims-making analysis examines the way in which the claim that extractive dredging was an environmental problem for the Brisbane River was constructed and contested. The actor-network analysis compares the two competing actor-networks that were developed by one of the major concrete companies and by the anti-dredging campaigners. The boundary-work analysis examines the social construction of the science / politics border as an important site of boundary-work, before exploring other related forms of boundary-work within the case study. When combined, these theories highlight the social and political processes that underpin the inherent difficulties associated with applying science to effective environmental dispute resolution. The theoretical framework developed in this thesis highlights the way in which an analysis of environmental claims-making, actor-networks and boundary-work, extends the literature on environmental dispute resolution. This thesis therefore makes a significant contribution to the field of environmental dispute resolution, by illustrating the advantages of drawing on theoretical perspectives from environmental sociology and the sociology of scientific knowledge.

Full textAbstract:
Les reactions de couplage reducteur des cetones en diols et en olefines sont devenues en 25 ans une methode classique de synthese en chimie organique pour la formation de liaisons carbone-carbone. En etudiant le comportement des complexes de l'uranium dans de telles reactions, notre but n'etait pas de trouver une solution alternative a l'utilisation des composes du titane ou du samarium, mais d'etudier le mecanisme reactionnel. Un des leitmotivs de ce travail a ete d'etablir, aussi souvent que possible, des paralleles entre nos resultats et les donnees de la litterature concernant les reactions de couplage au moyen d'autres reactifs. Au dela de l'uranium, nous avions l'ambition d'etudier la reactivite des metaux oxophiles et reducteurs vis-a-vis des composes carbonyles. Notre etude de la reaction de couplage reducteur des cetones au moyen des complexes de l'uranium s'est faite en trois parties: 1) nous avons tout d'abord etudie le mecanisme de la reduction du tetrachlorure d'uranium par voltammetrie cyclique. Nous avons montre que cette reduction s'accompagne d'une reaction de transfert de chlorures entre l'espece reduite de plus grande densite electronique et ucl#4 present dans le milieu. 2) dans un deuxieme temps, nous avons etudie trois aspects du mecanisme de la reaction de mcmurry : la synthese, la structure et la reactivite des intermediaires, la stereochimie de la formation des diols et des alcenes, la catalyse de la reaction de pinacolisation. 3) nous nous sommes enfin interesses aux limites de la reaction de mcmurry en etudiant les sous-produits de la reaction de pinacolisation des cetones aromatiques. L'ensemble de ces resultats montrent que les complexes des metaux presentant un fort caractere oxophile et reducteur (ti, sm, u) reagissent de facon similaire avec les composes carbonyles. Si les composes de l'uranium sont moins utilises que ceux du titane dans le domaine des applications en syntheses organique, ils sont des auxiliaires precieux et d'excellents modeles pour l'etude des mecanismes reactionnels, et pour l'amelioration des methodes de synthese.

Full textAbstract:
[EN] The Monastery of the Mare de Dèu de la Murta, belonging to the Order of Saint Jerome, came to be a cultural landmark with a remarkable architectural heritage. After the confiscation it passed into private hands, with the consequent secularization of the monastic community that housed, and underwent a process of plundering and abandonment that made its ruin. Located in a natural area of great value and linked to the customs of the city of Alzira, it is a set in which natural, intangible and built heritage are enhanced.
Within the monastic complex, two of the elements that were the most important, and that as many remains have come down to us, are the church and the Tower dels Coloms (defensive element with characteristics of military architecture). Both are the representative image of the Valley today and are the object of study of this doctoral thesis.
The church, built between the sixteenth and seventeenth centuries, was covered with a structural system consisting serialization sail domes without ribs, made with the tile vault technique. Within the process of formal and technological transition that leads from the ribbed vaults of the Gothic to barrel vault with lunettes typical of the Counter-Reformation churches, the examples in which the nave is covered with sail vaults without ribs are scarce and built in a very specific chronological period. We have analyzed several examples that share technical similarities and chronological period to locate the system in this process of change, and determine which should be the structural and constructive solutions that had to be used to built the church of La Murta.
This change of vaulting system, powered by stylistic issues, had significant structural connotations. The behavior of different types of dome that temporarily coexisted are studied to determine the characteristics it won or lost with this change regarding its mechanical capabilities and structural performance. In this research are included the influences of the rigidization systems of the vaults, as fillers or tabs, and the different ways of realizing the covers.
It is also presented a virtual restoration of the church and the Tower dels Coloms from the point of view of construction, where it is studied the behavior of both elements, under vertical loads and also its ability to earthquake responses.
Finally, it is analyzed the structural response of the remains wall in its current configuration of ruin, again in both cases: gravitational actions and seismic actions.
The models have been defined from the planimetric surveys based on point clouds obtained with photogrammetric techniques. It has been used the limit analysis, from graphic methods, and the FEM with continuous damage modeling, able to reproduce the behavior of the masonry, for the structural analysis of the elements.
The results obtained confirm the validity of the reconstructive hypothesis and provide data on what should be the behavior of the original structure. Also it shows the strengths and weaknesses of remains that have come down to us in order to guide future interventions aimed to ensure its permanence.[ES] El monasterio de la Mare de Dèu de la Murta en Alzira, perteneciente a la orden Jerónima, llegó a constituir un punto de referencia cultural, con un notable patrimonio edificado. Tras la desamortización pasó a manos privadas, con la consiguiente exclaustración de la comunidad monástica que albergaba, y sufrió un proceso de expolio y abandono que lo convirtió en ruina. Ubicado en un espacio natural de gran valor y vinculado a las costumbres de la ciudad de Alzira, es un conjunto en el que patrimonio natural, inmaterial y edificado se potencian. Dentro del conjunto monacal, dos de los elementos que fueron de mayor importancia, y de los que mayor cantidad de restos han llegado hasta nosotros, son la iglesia y la Torre de las Palomas, elemento defensivo con características de arquitectura militar. Ambos constituyen la imagen representativa del Valle en la actualidad y son el objeto de estudio de esta tesis doctoral. La iglesia, construida entre los siglos XVI y XVII, se cubrió con un sistema estructural formado por la seriación de bóvedas baídas sin nervaturas, realizadas con la técnica tabicada. Dentro del proceso de transición formal y tecnológica que conduce desde las bóvedas nervadas del gótico hasta la nave de cañón con lunetos típica de las iglesias contrarreformistas, y a diferencia de estos dos modelos, los ejemplos en los que la nave principal se cubre con bóvedas baídas sin nervaturas, son escasos y construidos en un periodo cronológico muy concreto. Con el fin de ubicar el sistema dentro de este proceso de cambio, y de determinar cuáles fueron las soluciones estructurales y constructivas con las que debió estar edificada la iglesia de La Murta, se han analizado varios de los ejemplos con los que comparte similitudes técnicas y periodo cronológico. Este cambio de sistema de abovedamiento, impulsado por cuestiones estilísticas, tuvo importantes connotaciones estructurales. Para determinar los comportamientos de los diferentes tipos de bóveda que coexistieron temporalmente, y lo ganado o perdido con el cambio, en lo referente a capacidades mecánicas, se estudian desde el punto de vista estructural los esquemas de funcionamiento y se obtienen las capacidades portantes de todos ellos. En la investigación se incluyen las influencias de los sistemas de rigidización de las bóvedas, como rellenos o lengüetas, y de las diferentes maneras de materializar las cubiertas. Asimismo se presenta una restitución virtual de la iglesia y la Torre de las Palomas desde el punto de vista constructivo, donde se estudia el comportamiento de ambos elementos, tanto frente a cargas verticales como su capacidad de respuestas frente al sismo. Por último, se analiza la respuesta estructural de los restos murarios en su configuración actual de ruina, de nuevo tanto frente a acciones gravitatorias como frente a acciones sísmicas. Los modelos se han definido a partir de los levantamientos planimétricos basados en las nubes de puntos obtenidas con técnicas fotogramétricas. Para el análisis estructural de los elementos se han utilizado tanto el análisis límite, a partir de métodos gráficos, como el MEF con modelización de daño continuo, capaz de reproducir el comportamiento de las fábricas. Los resultados obtenidos permiten ratificar la validez de la hipótesis reconstructiva planteada, aportan datos sobre cuál debió ser el comportamiento de la estructura original, y evidencian las capacidades y debilidades de los restos que han llegado hasta nosotros, con el fin de guiar las intervenciones futuras encaminadas a garantizar su permanencia.
[CAT] El monestir de la Mare de Dèu de la Murta a Alzira, pertanyent a l'orde Jerònim, va arribar a constituir un punt de referència cultural, amb un notable patrimoni edificat. Després de la desamortització va passar a mans privades, amb la consegüent exclaustració de la comunitat monàstica que albergava, i va patir un procés d'espoli i abandó que el va convertir en ruïna. Situat en un espai natural de gran valor i vinculat als costums de la ciutat d'Alzira, és un conjunt en el qual patrimoni natural, immaterial i edificat es potencien. Dins del conjunt monacal, dos dels elements que tingueren major importància, i dels quals major quantitat de restes han arribat fins a nosaltres, són l'església i la Torre dels Coloms, element defensiu amb característiques d'arquitectura militar. Tots dos constitueixen la imatge representativa de la vall en l'actualitat i són l'objecte d'estudi d'aquesta tesi doctoral. L'església, construïda entre els segles XVI i XVII, es va cobrir amb un sistema estructural format per la seriació de voltes bufades sense nervadures, realitzades amb rajoles de pla. Dins del procés de transició formal i tecnològic que condueix des de les voltes nervades del gòtic fins a la nau de canó amb llunetes típica de les esglésies contrareformistes, i a diferència d'aquests dos models, els exemples en els quals la nau principal es cobreix amb voltes bufades sense nervadures són escassos i construïts en un període cronològic molt concret. Amb la finalitat de situar el sistema dins d'aquest procés de canvi, i de determinar quines foren les solucions estructurals i constructives amb les quals va haver d'estar edificada l'església de la Murta, s'han analitzat alguns dels exemples amb els quals comparteix similituds tècniques i període cronològic. Aquest canvi de sistema de en les voltes, impulsat per qüestions estilístiques, va tenir importants connotacions estructurals. Per determinar els comportaments dels diferents tipus de volta que van coexistir temporalment, allò guanyat o perdut amb el canvi referent a capacitats mecàniques, s'estudien des del punt de vista estructural els esquemes de funcionament i s'obtenen les capacitats resistents de tots ells. En la recerca s'inclouen les influències dels sistemes de rigidització de les voltes, com a reblits o llengüetes, i de les diferents maneres de materialitzar les cobertes. A més es presenta una restitució virtual de l'església i la Torre dels Coloms des del punt de vista constructiu, on s'estudia el comportament de tots dos elements, tant davant càrregues verticals com la seua capacitat de respostes enfront del sisme. Finalment, s'analitza la resposta estructural de les restes muràries en la seua configuració actual de ruïna, de nou tant enfront d'accions gravitatòries com enfront d'accions sísmiques. Els models s'han definit a partir dels alçaments planimètrics basats en els núvols de punts obtinguts amb tècniques fotogramètriques. Per a l'anàlisi estructural dels elements s'han utilitzat tant l'anàlisi límit, a partir de mètodes gràfics, com el MEF amb modelització de dany continu, capaç de reproduir el comportament de les fàbriques. Els resultats obtinguts permeten ratificar la validesa de la hipòtesi reconstructiva plantejada, aporten dades sobre quin va haver de ser el comportament de l'estructura original, i evidencien les capacitats i debilitats de les restes que han arribat fins a nosaltres, amb la finalitat de guiar les intervencions futures encaminades a garantir la seua permanència.

Full textAbstract:
This thesis explores the representation of negative and subversive aspects of the Royal Navy and its seamen during the French Wars, 1793-1815, in contemporary print culture. Visual analysis, supported by archival research, is used to show that evasion and exaggeration were key in the representation of such subjects. The figure of Jack Tar (the common seaman) and the facets of his service referenced in works on paper are investigated as constructs. It is argued that such historical documents confirmed and perpetuated misconceptions informed by dominant expectations, values and concerns. Such depictions, often satirical, are indicative of broader material and ideological contexts. Issues collectively and individually salient for Britons’ and naval seamen are shown to have included those of identity, liberty, state power, subordination, morality and sacrifice. These are revealed to be central to the construction of the notorious naval tar by printmakers, audiences, writers, publishers, politicians, officers, seamen themselves and even historians. In a chronological narrative from recruitment to cessation of service, the thesis explores the experiences of this infamous naval character through his contemporary representation.

A hipertensão arterial sistêmica é fundamentada como uma condição clínica multifatorial caracterizada por níveis elevados e sustentados de pressão arterial. A progressão da doença está intimamente ligada com alterações estruturais e funcionais cardíacas e vasculares além de promover danos em alguns órgãos alvo, como os rins, cérebro, além das alterações metabólicas, que produzem um aumento sensível nos riscos de doenças cardiovasculares. De acordo com a Sociedade Brasileira de Cardiologia a hipertensão arterial sistêmica apresenta uma alta prevalência e baixas taxas de controle, tornando-a um dos mais importantes problemas de saúde pública no Brasil. O uso de plantas medicinais para fins terapêuticos é bastante antigo e muitas vezes seu uso é absolutamente empírico, sem nenhum estudo científico que embase essa prática. A Blepharocalyx salicifolius, conhecida como Murta, apresenta várias utilidades terapêuticas baseadas no conhecimento popular, entre elas o uso como digestivo, antibacteriano, antiespasmódico e anti-hipertensivo, entre outros. No presente trabalho foi avaliado o efeito hipotensor do extrato aquoso da B. salicifolius em ratos normotensos, e analisado, através do uso do L-NAME, da losartan e do hexametônio, qual seria seu possível mecanismo de ação. A avaliação dos efeitos hemodinâmicos foi realizada em ratos wistar normotensos, anestesiados com uretana (1,4 mg/Kg i.p.) e via canulação da artéria carótida (para a verificação da PAS, PAD e FC) e da veia jugular (para administração do extrato e drogas). O primeiro protocolo foi realizado para verificação do efeito do extrato sobre os parâmetros hemodinâmicos, utilizando uma curva dose-crescente do extrato (10, 25, 50, 75 e 100 mg/Kg) via intravenosa individualmente (cada grupo contendo 6 animais). O extrato aquoso foi administrado após 30 minutos de estabilização no equipamento, e permaneceram por 60 min. O segundo protocolo foi para avaliar alguns dos possíveis mecanismos envolvidos na resposta hipotensora. Foram utilizados: um inibidor da óxido nítrico sintase - L-NAME (L-NG-nitroarginina metil ester) (30 mg/kg); um antagonista do receptor AT1 - Losartan, (10 mg/Kg), e um bloqueador ganglionar, Hexamêtonio (20mg/Kg). As drogas foram administradas após a estabilização, sendo feito uma nova estabilização para a administração do extrato (concentração 7,5 mg/Kg; volume de 200 μL) e registros realizados por 60 min. O extrato aquoso da B. salicifolius mostrou-se um potente hipotensor, reduzindo a pressão arterial de forma dose-independente, já que as quedas foram semelhantes indiferentemente da dose usada, sem provocar alterações na frequência cardíaca. Na avaliação dos possíveis mecanismos de ação foi observado que o bloqueio do receptor AT1 e administrado o extrato aquoso não houve modificação na hipotensão provocada pelo Losartan bem como após o bloqueio ganglionar com o hexametônio. Já quando induzida a hipertensão por L-NAME, o extrato aquoso causou queda de pressão arterial, sugerindo que a via do óxido nítrico não estaria envolvida. Estes resultados evidenciam pela primeira vez que o efeito hipotensor da administração aguda do extrato aquoso de Blepharocalyx salicifolius, possa ser via bloqueio dos receptores de angiotensina II tipo I e pela possível diminuição da resposta autonômica simpática.
Hypertension is finds as a multifactorial clinical condition characterized by high and sustained levels of blood pressure. Disease progression are intimately linked with structural and functional cardiac and vascular changes, promoting some damage in target organs such as the kidneys, brain, in addition to metabolic changes that produce a significant increase in the risk of cardiovascular diseases. According to the Brazilian Society of Cardiology, hypertension has a high prevalence and low control rates, making it one of the most important public health problems in Brazil. The use of medicinal plants for therapeutic purposes is quite old and often its use is completely empirical, no scientific study that basement this practice. Blepharocalyx salicifolius, known as Murta, has several therapeutic utilities based on popular knowledge, including use as digestive, antibacterial, antispasmodic and antihypertensive, among others. The present study evaluated the hypotensive effect of aqueous extract of B. salicifolius in normotensive rats and analyzed with L-NAME, the losartan and hexamethonium, which would be its possible mechanism of action. The evaluation of the hemodynamic effects was perform in normotensive Wistar rats, anesthetized with urethane (1.4 mg / kg i.p.) and cannulated in the carotid artery (for verification of SBP, DBP and HR) and the jugular vein (for administration of the extract and drugs). The first protocol was performed to verify the effect of the extract on the hemodynamic parameters using a dose increasing curve of the extract (10, 25, 50, 75 and 100 mg/kg) intravenously individually (each group containing six animals). The administration of the aqueous extract was after 30 minutes of stabilization in the equipment, and they remained for 60 min. The second protocol was to evaluate some of the possible mechanisms involved in the hypotensive response. Were used: an inhibitor of nitric oxide synthase - L-NAME (L-NG-L-nitroarginine methyl ester) (30 mg / kg); AT1 receptor antagonist - losartan (10 mg / kg), and a ganglionic blocker - hexamethonium (20mg/kg). Drug administration was performed after stabilization, performing a new stabilization for the administration of the extract and records kept for 60 min. The aqueous extract of B. salicifolius proved a potent hypotensive effect, reducing blood pressure in a dose-independent way since the declines were similar regardless of the dose used, and without effect on heart rate. In evaluation of the possible mechanism of action it was observed, when the AT1 receptor were blockade and the extract was administrated, that there was no change in blood pressure caused by losartan as after ganglionic blockage. When hypertension was induced by L-NAME, the extract caused arterial pressure low, suggesting that the nitric oxide pathway could not be involved. These results show for the first time that the hypotensive effect of acute administration of Blepharocalyx salicifolius aqueous extract may be by blockade of angiotensin II type 1 receptors and the possible reduction in sympathetic autonomic response.

Full textAbstract:
Recent advances in predictive dynamics allow the user to not only predict physics based human motion simulations but also determine the actuation torques required to achieve those motions. The predictive dynamics approach uses optimization to predict motion while using many task based, physics based, and environment based constraints including the equations of motion. Many tasks have been simulated using this new method of predicting and simulating digital human motion, e.g. walking, running, stair climbing, and box lifting. In this research, we develop a method to predict the motion as well as effect of external equipment hanging on the digital human. The proposed method is tested on a simple case of a two degree of freedom serial chain mechanism with a simple passive system to behave as external equipment. In particular, the passive mass is assumed to be attached to the two links system with a spring and damper. The results of the proposed method are compared with the results obtained by integrating the equations of motion of the full three degree of freedom system.

Full textAbstract:
In this study, I analyze the significance of Shakespearean intertextuality in the major works of Thomas Wolfe featuring protagonist Eugene Gant: Look Homeward, Angel and Of Time and the River. Specifically, I explore Gant's habits and preferences as a reader by examining the narrative arising from the protagonist's perspectives of Shakespeare's The Merchant of Venice, Hamlet, and King Lear. I examine the significance of parallel reading habits of Wolfe the author and Gant the character. I also scrutinize the plurality of Gant's methods of cognition as a reader who interprets texts, communicates his connections with texts, and wars with texts. Further, I assess the cumulative effect of Wolfe's having blurred the boundaries between fiction and reality, between the novel and drama. I assert, then, that Wolfe, by incorporating a Shakespearean intertext, reveals aspects indicative of postmodernism.

Els jerònims foren un moviment monàstic d’origen eremític que nasqué al regne de València l’any 1374 i que arribà a Catalunya a final del segle XIV amb la fundació, per part de la reina Violant, del monestir de Sant Jeroni de la Vall d’Hebron (1393), a Sant Genís dels Agudells, prop de Barcelona, que fou seguit per Sant Jeroni de Montolivet (1413), fundat pel mercader barceloní Bertran Nicolau, i que es traslladà a Badalona, tot donant lloc a Sant Jeroni de la Murtra (1416). Ambdós monestirs i llurs comunitats subsistiren fins al 1835.
El present treball té com a objectiu l’estudi global d’aquestes dues cases religioses des de les seves respectives fundacions fins a l’any 1500. Es basa en fonts documentals força diverses, des del que s’ha conservat dels antics arxius monàstics (pergamins, llibres d’administració i gestió, inventaris, etc.) fins a documentació notarial, reial i municipal, entre d’altres. S’ha estructurat en tres blocs fonamentals que n’abasten tots els àmbits: comunitat, activitat i relacions amb l’exterior. Aquest darrer capítol s’ha subdividit en quatre grans apartats que focalitzen la interacció amb diferents actors: benefactors, fonts econòmiques, estament eclesiàstic i estament polític. Després d’aquests tres grans capítols s’ha inclòs un quart sobre els dos edificis monàstics i la seva evolució constructiva. A partir de la integració de tots els capítols, es proposa una periodització de l’establiment dels jerònims a Catalunya en quatre grans etapes. L’estudi clou amb un apèndix que conté 52 taules documentals sobre diferents aspectes relacionats amb els dos monestirs, la transcripció completa de 128 documents i un recull de 72 imatges.The hieronymites were a monastic movement, with an eremitic origin, that was born in the kingdom of Valencia in 1374 and arrived in Catalonia at the end of fourteenth century with the foundation, by queen Violant de Bar, of the monastery of Sant Jeroni de la Vall d’Hebron (1393), in Sant Genís dels Agudells, near Barcelona, which was followed by Sant Jeroni de Montolivet, founded by the merchant of Barcelona Bertran Nicolau. This second monastery moved to Badalona in 1416 and became Sant Jeroni de la Murtra. Both monasteries and their communities remained until 1835. The aim of this research is a global study of these two monasteries from their respective foundations until 1500. It is based on diverse documentary sources: the documentation conserved of the ancient monastic archives (parchments, administration and management books, inventories, etc.), notarial, royal and municipal documentation, etc. This work has three fundamental blocks that cover all areas: community, activity and relationships with the outside. This last chapter has been subdivided into four main sections that focus on the interaction with benefactors, economic sources, Church and political power. After these three main chapters, there is a study of the two monastic buildings and their construction process. Finally, a periodization of the establishment of the hieronymites in Catalonia is proposed in four main stages. This study closes with and appendix that contains 52 documentary tables, the complete transcription of 128 documents and a collection of 72 pictures.

Full textAbstract:
Research and debates on gender have shown in the past 20-30 years the importance of gender relations to the realisation or achievement of women's development or lack of advancement. This thesis addresses two major themes: firstly, it links a detailed study of intra-household social relations in rural household livelihood strategies; and secondly examines empirically the relationship between women's participation in Non-Wood Forest Product (NWFP), in this case murta (a herbaceous reed) production and processing; and the position and status of women as well as men within their households through gender analysis of rural livelihood strategies among poor households in one village, in Sylhet district, Bangladesh. Murta is one of the major income generating activities in which women in poorer households are engaged to meet their subsistence needs. The research used a qualitative case study approach to understand gender and household livelihood strategies among the poor. A gender analysis of the division of labour was made relating to assets, access and activities; the culturally contracted terms about the division of resources and the pattern of negotiations that take place between household members among selected cases. The second section of this thesis examines women's and men's status defined in the following terms: i) their control over resources; ii) their decision-making power within their households; iii) the recognition women receive for their work from household members and the village community; iv) culturally constructed rules about social status. This study shows that income contribution has not improved women's relative well-being. The study on social relations improves understanding of the household's livelihood strategies more holistically by recognising gender inequalities in resources and status through the terms of cultural rules and negotiations. This study concludes with suggestions for policy interventions as follows: in future the government and NGOs planning for gender and development programmes in rural livelihoods need to look beyond the roles to understand the cultural rules as status signifiers that are placed on how people construct their livelihoods; but planning also need to address the joint interests of negotiations over gender relations at household level.

O huanglongbing (HLB), associada a bactérias de floema (Candidatus Liberibacter spp) transmitidas por insetos (Diaphorina citri), é a doença mais destrutiva dos citros e muitos têm sido os esforços visando reduzir sua disseminação nos pomares, porém, nem sempre bem-sucedidos. Somente no cinturão citrícola paulista mais de 45 milhões de plantas já foram erradicadas por causa do HLB. O objetivo deste trabalho foi investigar diferentes aspectos associados ao patossistema HLB, visando trazer informações que ajudem na contenção da doença. Foram estudados: 1) hospedeiros alternativos do inseto vetor e do patógeno; 2) ontogenia do broto vegetativo de citros e seu potencial em multiplicar D. citri; 3) requerimentos térmicos para o desenvolvimento do broto; e 4) influência do porta-enxerto na biologia de D. citri. No primeiro capítulo é apresentada revisão de literatura sobre os aspectos mais relevantes da citricultura e do patossistema em estudo e, nos demais, os resultados das pesquisas. No segundo é apresentada a importância Swinglea glutinosa (rutácea muito comum em certas regiões citrícolas) como fonte de Ca. Liberibacter asiaticus e criadouro de D. citri. A bactéria do HLB multiplicou na planta, porém atingiu populações consideravelmente menores do que em laranjeira ‘Valência’. Apresenta, portanto, baixo potencial como fonte de inóculo para os citros. Por outro lado, D. citri reproduziu abundantemente em S. glutinosa, tanto quanto nas principais variedades de laranjeiras doces e limoeiros do grupo ‘Siciliano’ cultivados no Brasil. No terceiro capítulo são apresentados detalhes do desenvolvimento do broto em laranjeira ‘Valência’ e como os diferentes estádios influenciam o potencial biótico de D. citri. O inseto completou seu ciclo de vida em todos os estádios, mas em diferentes intensidades, sendo maiores nos estádios iniciais. Com os dados criou-se um índice de favorabilidade à reprodução do inseto, que leva em consideração o peso relativo de cada estádio do broto na biologia do inseto. No quarto capítulo é apresentado o impacto da temperatura do ar sobre o broto, o que permitiu determinar os graus-dia necessários ao seu desenvolvimento (GDD) e, com base no GDD, estabelecer um modelo geral inovador de previsão de pulverizações. No quinto capítulo é demonstrado que o porta-enxerto (limoeiro Cravo, tangerineira Sunki e citrumeleiro Swingle), por mecanismos de antibiose e/ou antixenose, afetam D. citri. Mas esses fenômenos ocorrem somente na fase de seedlings, e nas copas neles enxertadas somente enquanto a planta é jovem (muda). Em plantas adultas, de maior porte, tais fenômenos não foram detectados. Podem ter sido mascarados por influência da variedade copa (laranjeira).
Huanglongbing (HLB), associated with insect-borne phloem bacteria (Candidatus Liberibacter spp), is the most destructive disease of citrus and many efforts have been made to reduce its spread in orchards, but not always well-succeeded. Only in the citrus belt of São Paulo state (Brazil), more than 45 million plants have already been eradicated because of HLB. The objective of this work was to investigate different aspects associated to the HLB pathosystem, aiming to bring information that helps in the management of the disease. We studied: 1) alternative vector insect and pathogen hosts; 2) ontogeny of the citrus vegetative shoot and its potential to multiply D. citri; 3) thermal requirements for shoot development; and 4) influence of the rootstock on the biology of D. citri. In the first chapter, a literature review on the most relevant aspects of citriculture and pathosystem in study is presented and, in the others, the results of the experiments. In the second one the importance of Swinglea glutinosa (a Rutaceae very common in certain citrus regions) as a source of Ca. Liberibacter asiaticus and host for D. citri is presented. The HLB bacteria multiplied in the plant, but reached populations considerably smaller than in 'Valencia' sweet orange. Therefore, it presents low potential as a source of inoculum for citrus. On the other hand, D. citri reproduced abundantly in S. glutinosa, as well as in the main sweet orange and lemon varieties of the 'Sicilian' group cultivated in Brazil. In the third chapter, it is presented details of the development of the 'Valencia' orange new shoot and how the different stages influence the biotic potential of D. citri. The insect completed its life cycle at all stages of new shoots, but at different intensities, being larger in the early stages. With the data, an insect reproduction index was created, which takes into account the relative weight of each shoot stage in the insect biology. In the fourth chapter, it is presented the impact of the air temperature on the shoot, which allowed to determine the degree-days required for its development (GDD) and, based on the GDD, to establish an innovative general model of spray forecasting. In the fifth chapter it is demonstrated that the rootstock (‘Rangpur’ lime, ‘Sunki’ mandarin and ‘Swingle’ citrumelo), by mechanisms of antibiosis and / or antixenosis, affect D. citri. But these phenomena occur only in the stage of seedlings, and in the scions grafted on them only while the plant is young (nursery tree). In larger adult plants, such phenomena were not detected. They may have been masked by the influence of the scion (orange) variety.

Full textAbstract:
A arborização urbana oferece diversos benefícios para a população, e sua necessidade vem aumentando com o crescimento das cidades. Mas como qualquer outro equipamento urbano, existe custo de implantação, manutenção e, também, prejuízos. Dentre os potenciais prejuízos da arborização urbana, estão os danos em calçamentos e estruturas de construção civil. Este trabalho objetivou identificar quais os parâmetros que influenciam esses danos e, auxiliar na definição de políticas públicas para a arborização urbana. O estudo baseou-se no Inventário da Arborização Urbana do Município de Piracicaba, em 15 bairros. Para todo o inventário, foram identificadas as unidades e profundidades do solo baseado no Levantamento Pedológico Semidetalhado do Município de Piracicaba. Optou-se por utilizar, para análise das trincas na calçada, uma espécie arbórea, a sibipiruna (Caesalpinia pluviosa Dc.) e, uma arbustiva, a falsa-murta (Murraya paniculata (L.) Jacq.), pois existe um conceito amplamente difundido, de que, as espécies arbustivas, não causam danos ao calçamento; já, as arbóreas, são conhecidas por danificar as calçadas. Na coleta de campo, avaliou-se os seguintes itens: endereço, espécie, árvore suprimida ou substituída, CAP, tamanho do canteiro, colo pavimentado, poda da parte aérea, estrutura urbana danificada, condições da calçada e material do piso. O índice de supressão da falsa-murta foi igual ao da sibipiruna (1,7%), sendo que 89,2% das falsamurtas e 92,6% das sibipirunas não foram substituídas por outra espécie. Para a falsamurta, a concentração de indivíduos, se deu na faixa de CAP de 21 a 80 cm (82,9%); 70,2% apresentaram trincas na calçada e 29,8% ausência de trincas; 44,6% dos indivíduos tinham canteiro de até 0,20 m2; 92,3% dos indivíduos sofreram poda considerada ruim e 75,1% dos indivíduos estavam em calçada de cimento. Para a sibipiruna, a concentração de indivíduos se deu na faixa de CAP de 101 a 160 cm (57,0%); 99,4% apresentaram trincas na calçada e 0,6% ausência de trincas; 44,6% dos indivíduos estavam plantados em locais classificados como canteiros indefinidos; 94,6% dos indivíduos sofreram poda considerada ruim e a calçada mais comum foi a de cimento com 63,1% de indivíduos. A profundidade do solo não teve influência em causar ou não trincas nas duas espécies. Com a análise estatística (teste Quiquadrado) pôde-se contrapor alguns conceitos difundidos na arborização urbana, concluindo-se que os arbustos também causam danos e as podas influenciam nos danos em calçadas, entre outras. Não existe solução simples para eliminação do conflito entre as árvores viárias e os equipamentos e estruturas urbanas. A população precisa e deve ser informada sobre todos os parâmetros, opções, benefícios e prejuízos de cada ação que estimule ou iniba o plantio de uma árvore em calçada.The urban forestry offers several benefits for the population and their need is increasing with the growth of cities. But like other urban equipment, there is cost of implementation, maintenance, and also losses. Among the potential damage of urban forestry, are paving the damage to structures and construction. This study aimed to identify the parameters that influence the damage and assist in the definition of public policies for urban forestry. The study was based on an inventory of urban forestry of the city of Piracicaba, in 15 districts. For the entire inventory, the units were identified and depths based on soil survey Pedológica semidetailed the city of Piracicaba. Was used for analysis of cracks in the sidewalk, a tree species, the sibipiruna (Caesalpinia rainy Dc.), And a bush, the falsa-murta (Murraya paniculata (L.) Jacq.), There is a concept widely widespread, that the shrub species, do not cause damage to the paving, while the trees are known to damage the sidewalks. In collecting field and focuses on the following: address, sort, tree removed or replaced, CAP, bed size, lap paved, pruning of shoots, damaged urban structure, and material conditions of the pavement of the floor. The rate of elimination of falsa-murta was equal to the sibipiruna (1.7%), whereas 89.2% of falsa-murta and 92.6% of sibipiruna were not replaced by other species. For the falsemyrtle, the concentration of individuals, was in the range of CAP 21 to 80 cm (82.9%), 70.2% had cracks in the sidewalk and 29.8% no broken; 44.6% of individuals had bed tree to 0.20 m2, 92.3% of individuals have suffered as bad pruning and 75.1% of individuals were in sidewalk cement. For sibipiruna, the concentration of individuals was in the range of 101 to 160 CAP cm (57.0%), 99.4% had cracks in the sidewalk and 0.6% absence of cracks, 44.6% of individuals were planted in locations classified as uncertain beds trees, 94.6% of individuals have suffered as bad pruning and sidewalk was the most common cement with 63.1% of individuals. The depth of soil had no influence on whether or not cause cracks in the two species. With the statistical analysis (Chi-square) could be countered some concepts available in urban forestry, concluding that the damage also shrubs and pruning influence the damage to sidewalks, among others. There is no simple solution to eliminate the conflict between the trees and road equipment and urban structures. The people need and should be informed about all parameters, options, benefits and harm of each action that stimulate or inhibit the planting of a tree in the sidewalk.

Full textAbstract:
This work present a physical, chemical and microbiological study of groundwater, spring and stream water of Água Santa and Palmeiras basin from Middle River Jequitinhonha Valley, Coronel Murta (MG). In this place, mineral exploration activitie is developed on pegmatite to extraction of gem, that constitute the main income source of the local population. In contrast with the mineral wealth, the area is placed among the Brazilian regions with the most precarious economic conditions, being extremely important the water scarcity problem with low precipitations and high temperatures averages. Mineral activity and the lack of basic sanitation facility in the village and garimpo constitute potential factors of contamination of the hydric system. In this context, the main goal of this work is to determinate the quality of water in areas of influence of garimpos and parallely, determinate parameters of the potentialities of the hydric system in order to subsidize future action of adjusted handling. The monitoring net implanted for the study is integrated for fifteen sampling points that include springs, surface and groundwaters samples were collected for represent one hydrologic year, with samplings in the dry, rainy and intermediate seasons. The hydrochemical characterization of the springs, surface and groundwaters indicates that the dominant concentration of ions can be related to the alteration of local lithology. The result of electric conductivity and dissolved solids obtained for the water from garimpo of the Palmeiras basin, demonstrate the low salinity of this water. The bicarbonated water is the dominant type. Usually, high value of electric conductivity is associated to the load contaminante in the water, such as high content in nitrate in the garimpo of Água Santa Stream and high content of organic materia in surface water, related to launching of domestic effluent and wastewater. The evaluations of waters quality of both basins disclose physical, chemical and microbiological features in disagreement with the standards for surface waters quality and also with those established for underground waters. Microbiological contaminante is present in all the sampling points. The results gotten in this study demonstrate that the adoption of measures that guarantee the permanent flow and quality of waters of Água Santa e Palmeiras streams are necessary. Examples of these measures are preservation of spring areas; recovery of stream-edge vegetation; implantation of system for collect and treatment of domestic effluents; garbage collection; education related to environmental preservation of water and vegetation, as well as the adequate disposal of mining residues. The points of water occurrence in areas of mineral activities are potential for high quality water captation and, at the same time, they configure a canal of direct contact with thegroundwater system. Of this form, they are necessary hydrodynamic studies and the adoption of measures that guarantee its quality and rational usage.Este trabalho apresenta a caracterização fisica, química e microbiológica de águas subterrânea, de nascentes e águas superfícais das bacials hidrográficas dos córregos Água Santa e Palmeiras, inseridas no Médio Vale do Rio Jequitinhonha, Município de Coronel Murta (MG). Nestes locais são desenvolvidas atividades de garimpagem de corpos pegmatíticos para extração de gemas, que constitlem a principal fonte de renda para a população local. Em contraste com a riqueza mineral, a região está inserida no contexto do semi-árido brasileiro, o qual é caracterizado por baixas precipitações, médias de temperaturas elevadas e condições sócio-econômicas extremamente precárias da população que colocam a região entre as de maior pobreza do Brasil. Atividades minerárias e a ausência de infraestrutura de saneamento básico nas vilas e garimpos constituem fatores potenciais de contaminação do sistema hídrico. Neste contextc, o objetivo principal do trabalho é a caracterização fisico-química e microbiológica das águas do Municipio de Coronel Murta em áreas de influência de garimpos e paralelamente, a avaliação das potencialidades dos recursos hídricos de modo a subsidiar ações futuras que promovam seu manejo adequado, estabelecendo alvos potenciais de captação e/ou restringindo o uso de mananciais. A rede de monitoramento implantada neste estudo é composta por quinze pontos de amostragem que incluem nascentes, águas superfichis e subterrâneas. O monitoramento foi baseado em um ano hidrológico, sendo realizadas amostragens nos períodos seco, chuvoso e intermediário. A caracterização hidroquímica das nascentes, águas superfícais e subterrâneas indica que as concentrações dos íons dominantes podem fer relacionadas ao intemperismo das Iitologias que caracterizam a área de estudo. As águas ocorrentes nas lavras pegmatíticas localizadas na Bacia do Córrego Palmeiras apresentam valor médio de 41,3 ìlS/cm para condutividade elétrica e 55,4 mg/1 para sólidos dissolvidos. Estes resultados demonstram a baixa salinidade das águas ocorrentes nestas lavras. As águas são predominantemente do tipo bicarbonatadas, e a ordem de predominância dos cátions dominantes é rMg2+>rNa+ >rK+ >rCa2+. Valores excessivamente elevados de condutividade elétrica estão, via de regra, associados à existência de cargas contaminantes nas águas, tais como o conteúdo elevado em nitrato na lavra localizada na Bacia do Córrego Água Santa e alto conteúdo orgânico especialmente em águas superficiais, em função do lançamento de efluentes domésticos. As avaliações de qualidade das águas das duas bacias revelam parâmetros físicos, químicos e microbiológicos em desacordo com os padrões de qualidade tanto para águas superfícais, quanto para as águas subterrâneas. Os parâmetros microbiológicos constituem a carga contaminante comum a todos os pontos de amostragem. Os resultados obtidos neste estudo demonstram a necessidade da adoção de medidas que garantam a perenidade e qualidade das águas dos córregos Água Santa e Palmeiras como a preservação de áreas de nascentes; recuperação de mata ciliar; implantação de sistema de coleta e tratamento de esgotos domésticos; implantação de sistema de coleta dp, lixo; conscientização da população em relação à preservação dos recursos hídricos e matas ciliares, bem como a disposição adequada de resíduos de mineração. As águas ocorrentes em lavras pegmatíticas representam pontos potenciais de captação de água e ao mesme tempo configuram um canal de contato direto com o sistema subterrâneo. Desta forma, são necessários estudos hidrodinâmicos e a adoção de medidas que garantam sua qualidade e uso racional.

Full textAbstract:
Denna uppsats belyser hur vi kan hantera etnisk och kulturell olikhet i svensk skola. Detta kan ske genom att det interkulturella perspektivet är utgångspunkt för lärandet och undervisningen. Syftet är således att beskriva och analysera begreppet interkulturalitet i anknytning till det integrativa arbetet i svensk skola. För att nå uppsatsens syfte har jag tre frågeställningar:
Vad innebär ett interkulturellt perspektiv?
Hur kan interkulturalitet komma till uttryck i lärandet och undervisningen?
Hur kommer det interkulturella perspektivet till uttryck i några olika skolors verksamhetsplaner?
Jag har använt mig av en kvalitativ textanalys för att ta mig an de preciserade frågeställningarna ovan och uppsatsens syfte. Analysen är uppdelad i två delar – en litteraturgenomgång och en dokumentanalys. Litteraturgenomgången söker svar på de två förstnämnda frågeställningarna. Ur denna genomgång har åtta frågor växt fram som ligger till grund för analysen av olika skolors verksamhetsplaner.
Det finns mycket skrivet om det interkulturella lärandet och undervisningen. Resultatet visar att det går att hantera interkulturalitet i skolan oavsett om etnisk eller kulturell olikhet är rådande. Men skolans organisationsnivå med avgränsning till verksamhetsplanerna är uppenbart monokulturell i min undersökning. Vidare är det interkulturella perspektivet begränsat till skolor som har mycket hög andel elever med utländsk bakgrund. Det interkulturella perspektivet är därmed svårt att finna i de undersökta skolornas verksamhetsplaner. Hanteringen av etnisk och kulturell olikhet måste utvecklas, då vi i ett samhälle är beroende av varandra. Det krävs också att skolan blir den sociala mötesplatsen för denna olikhet.
The essay will illustrate how we could handle the ethnic and cultural differences in the swedish school. This could be done by using un intercultural perspective as a starting point when teaching and educating. Therefore the purpose is to describe and analyze interculturality in association to the integrational work in the swedish school. To reach the purpose with this essay I have three questionings:
What is the meaning of an intercultural perspective?
How can the interculturality be expressed within the teaching and education?
In what ways are the intercultural perspective expressed in local documents from schools in which they describe their aims, the purpose of them and how to go about it?
I have used a qualitative way in which to analyze text regarding the questions above, and the purpose of this essay. The analysis is split into two parts. The first part is concentrating on texts concerning literature which elaborates the first two research questions above. In the second part I analyze documents from schools which elaborate what the schools aim to do, why and how. This analysis will answer the third question above.
There has been a lot written about the intercultural teaching and education. The result shows that it is possible to handle interculturality in the schools regardless of an ethnic or cultural difference. However, the organization levels, being restricted to the school planning documents, are obviously monocultural by large. The intercultural perspective is limited to schools with a high level of students with a foreign background. The intercultural perspective is therefore difficult to find in the examined. The handling of ethnic and cultural differences must be developed, as in a community we are dependant upon each other. That would also mean that the school would have to be the social gathering point for the differences in an increasingly intercultural world.

Full textAbstract:
In February 2014, a coal ash spill on Duke Energy's Dan River Plant in Eden, NC released approximately 39,000 tons of coal ash into the Dan River. It took approximately one week to stop the spill.
Starting in February 2015, drinking water utilities using the Dan River experienced a series of taste and odor (TandO) events described as "earthy" or "musty". Similar TandO events were not documented before the coal ash spill.
This research attempted to understand causes of the TandO events and if the coal ash spill was connected. A variety of water quality analyses were performed on twelve sites from August 2016 to September 2017 on the Dan and Smith Rivers. The Smith River served as the control.
From concentrations of coal ash indicators (particularly Ba, Sr, As, V, and Br-), there was a signature of coal ash on the Dan River that was not present on the Smith River. The signature could not be attributed to the coal ash spill, as the signature was present upstream of the spill. Chronic ecosystem toxicity due to metals was low and not significantly different between the Dan and Smith Rivers.
No substantial TandO events occurred during the period of this study. All monitored odorants were detected with varying frequencies in both the Dan and Smith Rivers. No significant change in odorant concentration was found above and below the location of the coal ash spill.MS

La incidència sobre el suro de defectes sensorials amb descriptors de florit-humitat és un dels principals problemes amb què s'enfronta la indústria surera. Els principals compostos relacionats amb aquest defecte son cloroanisoles, metoxipirazines, geosmina i metilisoborneol. Aquesta recerca s'ha fet amb l'objectiu principal d'aprofundir en els mètodes de determinació de compostos volàtils en suro. S'ha desenvolupat una metodologia basada en la microextracció en fase sòlida i la cromatografia de gasos per a l'anàlisi conjunta d'aquests compostos en macerats de suro. El fet que la majoria dels compostos d'interès tingui un origen microbià ha fet necessari completar les anàlisis químiques amb mètodes de detecció i aïllament dels microorganismes susceptibles de produir-los. S'ha utilitzat un mètode per a l'estudi de la diversitat de fongs i bacteris en mostres de suro basat en l'estudi de marcadors genètics mitjançant l'anàlisi en gradients electroforètics desnaturalitzants. Per últim s'ha avaluat la capacitat de producció de defectes sensorials per microorganismes aïllats de suro utilitzant tècniques olfactomètriques.The incidence of musty-earthy sensory deviations on cork is one of the main problems that the cork industry faces. The main compounds related to this defect are chloroanisoles, methoxypyrazines, geosmin and methylisoborneol. The aim of this research work was to develop analytical methods to simultaneously determine a large set of volatile compounds in cork samples. A methodology based on solid phase microextraction (SPME) and gas chromatography for the determination of TCA, 3-isopropyl-2-methoxypyrazine, geosmin and methylisoborneol in cork aqueous macerates has been developed and validated. Moreover, the microbial origin of most of these compounds makes necessary to complement the chemical analysis with the detection and isolation of microorganisms that may be involved in the production of off-odours. Regular fingerprinting techniques for the analysis of microbial diversity such as Denaturing Gradient Gel Electrophoresis (DGGE) have been applied to the study of microorganism potentially responsible for off-odour formation in cork, in order to complement the chemical characterization of the volatile fraction. Finally we have evaluated the off-odour production capacity of microorganisms isolated from cork using olfactometry techniques.

Full textAbstract:
Ce travail arpente le domaine de ce qu’Albert Thibaudet nommait « la critique des artistes » pour montrer que, au cours de la seconde moitié du XXe siècle, ce genre de critique a constitué un véritable laboratoire permettant de sortir des impasses auxquelles avait conduit la vision autotélique de l’œuvre proposée par la critique formaliste et par la néo-avant-garde. Dans la première partie de l’étude on s’interroge sur l’évolution de la critique formaliste, en envisageant le tournant linguistique des années 1960 comme l’aboutissement naturel d’une révolution culturelle qui a eu lieu à la fin du XIXe siècle. En menant une analyse comparée entre la France et l’Italie, on observe les deux critiques formalistes en-dehors de leur rapport de filiation, et on brosse un modèle transnational qui montre qu’elles partagent la même conception de la littérature postulée par la néo-avant-garde. La deuxième partie du travail est consacrée à l’analyse d’une tendance relevable dans la critique des écrivains à partir de l’après-guerre, où une étude purement intrinsèque de l’œuvre d’art est mise en discussion. On propose une analyse comparée de la critique littéraire de Georges Perec, Michel Tournier, Philippe Muray, Tommaso Landolfi, Pier Paolo Pasolini et Pier Vittorio Tondelli, afin de souligner que leur pratique critique ne s’est pas limitée à une déclaration personnelle de poétique, mais elle a ouvert une voie alternative à l’exaspération des positions théoriques formalistes, en anticipant ou en prônant le dépassement d’une vision autoréférentielle de l’œuvre qui a caractérisé la littérature de la fin du XXe siècle aussi bien en France qu’en ItalieMy dissertation covers the field of what Albert Thibaudet called “the critique of artists” in order to show that, throughout the second half of the twentieth century, this form of criticism has given readers a different perspective on literature in comparison to that of the formalists and the neo-avant-garde. In the first part of my study, I examine the evolution of formalist criticism in the twentieth century, considering the linguistic turn of the 1960s as the natural outcome of a cultural revolution which took place at the end of the nineteenth century. By conducting a comparative study between France and Italy, I attempt to outline a transnational model which shows that the two formalist critiques share the same understanding of the literature postulated by the neo-avant-garde. The second part of my thesis is devoted to the study of one of the main tendencies in the critique of the writers since the Second World War, a tendency that called into question a purely intrinsic study of the work of art. Here, I propose a comparative study of the literary critique of Georges Perec, Michel Tournier, Philippe Muray, Tommaso Landolfi, Pier Paolo Pasolini and Pier Vittorio Tondelli, in order to underline that their critical practice has not limited itself to a personal declaration of their poetic views, but it has truly opened up an alternative approach to formalist theoretical positions. They refused to speak of literature as a secluded world, and by doing so they anticipated one of the most important features of the literature of the end of the twentieth century, both in France and in Italy

This work mainly studies modeling and existence issues for martingale models of option markets with one stock and a collection of European call options for one fixed maturity and infinetely many strikes. In particular, we study Dupire's and Schweizer-Wissel's models, especially the latter one. These two types of models have two completely different pricing approachs, one of which is martingale approach (in Dupire's model), and other one is a market approach (in Schweizer-Wissel's model). After arguing that Dupire's model suffers from the several lacks comparing to Schweizer-Wissel's model, we extend the latter one to get the variations for the case of options on interest rate indexes and futures options. Our models are based on the newly introduced definitions of local implied volatilities and a price level proposed by Schweizer and Wissel. We get explicit expressions of option prices as functions of the local implied volatilities and the price levels in our variations of models. Afterwards, the absence of the dynamic arbitrage in the market for such models can be described in terms of the drift restrictions on the models' coefficients. Finally we demonstrate the application of such models by a simple example of an investment portfolio to show how Schweizer-Wissel's model works generally.

O objetivo do presente trabalho foi avaliar a influência de variedades comerciais de citros e de murta no desenvolvimento de Diaphorina citri Kuwayama, 1908 e a preferência do parasitoide Tamarixia radiata (Waterson, 1922) sobre o referido psilídeo, criado em diferentes variedades cítricas e na murta, por meio de estudos biológicos e comportamentais, para definir estratégias de controle da praga em programas de MIP em citros. Foram realizados testes de livre escolha e confinamento (sem chance de escolha) para avaliar o efeito de variedades de citros sobre a alimentação e fertilidade de D. citri, bem como a biologia da referida espécie de psilídeo em diferentes hospedeiros. Avaliou-se ainda o efeito da variedade de citros sobre o parasitismo de T. radiata, bem como sua biologia em D. citri criado em diferentes hospedeiros. Pode-se concluir que: D. citri preferiu ovipositar e se alimentar, em teste de livre escolha, em \'Natal\', sendo que no teste de confinamento (sem chance de escolha) a oviposição foi semelhante em \'Natal\', \'Valência\' e \'Pêra\'. Em ambos os tipos de teste, \'Hamlin\' foi a menos adequada para D. citri. Com base nos demais parâmetros biológicos avaliados, a análise de agrupamento separou os hospedeiros em três grupos distintos, sendo \'Valência\' e murta os hospedeiros mais adequados ao desenvolvimento de D. citri. No segundo grupo (\'Natal\', \'Pêra\' e \'Ponkan\') concentraram-se as variedades que proporcionaram um desenvolvimento intermediário ao psilídeo, sendo \'Hamlin\' a menos adequada ao desenvolvimento do inseto. Com base na tabela de vida de fertilidade, a taxa líquida de reprodução (Ro) de D. citri foi 2,5 vezes maior quando criado em \'Valência\' em relação a \'Hamlin\'. Os demais parâmetros (T, λ e rm) também favoreceram o inseto quando criado em \'Valência\'. Os hospedeiros estudados não afetaram o parasitismo e desenvolvimento de T. radiata sobre D. citri. Os resultados obtidos poderão fornecer subsídios ao planejamento do plantio de variedades de citros em pomares novos com vistas à incidência e manejo do HLB.This research\'s aim was to evaluate the influence of commercial citrus varieties and orange jessamine on the development of Diaphorina citri Kuwayama, 1908 and the parasitoid Tamarixia radiata (Waterson, 1922) preference on the Asian Citrus Psyllid (ACP), reared on different citrus varieties and on orange jessamine, by the means of biological and behavioral studies, in order to establish strategies of pest control in Integrated Pest Management (IPM) citrus programs. Free-choice and nochoice tests were carried out to evaluate the citrus varieties effects on the feeding and fertility of D. citri, as well as the biology of this psyllid species on different hosts. It was evaluated the citrus variety effect on the T. radiata parasitization, as well as its biology with D. citri reared on different hosts. It can be concluded that: D. citri preferred laying eggs and feeding, in free-choice tests, on \'Natal\', while in the nochoice test, the laying-eggs behavior was the same on \'Natal\', \'Valência\' and \'Pêra\'. In the both tests, \'Hamlin\' was the least suitable for D. citri. According to the other biological characteristics evaluated, the grouping analysis identified 3 different groups, being \'Valência\' and orange jessamine the best hosts for D. citri development. In the second group (\'Natal\', \'Pêra\' e \'Ponkan\') are the varieties that provided a reasonable development to the psyllid, being \'Hamlin\' the least suitable for the insect development. According to the fertility life table, the reproduction net rate (Ro) of D. citri was 2,5 times bigger if reared on \'Valência\' compared to \'Hamlin\'. The other life table parameters (T, λ e rm) also supported the results when it was reared on \'Valência\'. The studied hosts did not affect the parasitization and the development of T. radiata on D. citri. The results obtained will provide information for planting planning of citrus varieties in new groves considering the HLB incidence and management.

Full textAbstract:
Près de soixante ans que la construction de l’Union européenne a commencé, se composant de six membres, au début, à vingt-sept aujourd’hui. Dans le même temps, tous les pays membres de l’UE ne s’impliquent pas au même rythme : espace Schengen à vingt-trois, Union monétaire à dix sept, coopérations renforcées et partenariats divers, « à la carte ». Face au contexte mondial, aux crises actuelles (surendettement public) et à venir (réchauffement climatique), aux problèmes juridiques soulevés par les ambiguïtés posées par la coexistence d’un marché unique, de droits nationaux concurrents et d’un droit européen en émergence, quel scénario politique est souhaitable et réalisable pour l’Union européenne en 2015 et en 2030 ? Les deux scénarii les plus probables pour 2015 semblent être le scénario d’une « Europe à géométrie variable », une fédération composée d’un noyau dur d’États membres, trois grands (Allemagne, France, Italie) et quatre petits réunis en un même sous-ensemble (le Benelux et l’Autriche) ainsi que le scénario d’une « union des États nations » correspondant au modèle institutionnel actuel régit par le traité de Lisbonne, mais ne semblant pas le plus approprié pour résoudre la crise actuelle. Pour résoudre la crise de surendettement public et les problèmes juridiques posés au sein de l’UE, le scénario « à géométrie variable » semble le plus adapté du fait de sa capacité à doter les institutions de pouvoirs d’action qui ne fonctionnent plus à l’échelle nationale et insuffisamment à l’échelle européenne (en matière budgétaire, monétaire et réglementaire). Le scénario souhaitable et potentiel pour 2030 est celui d’une Union fédérale pour l’ensemble des États membres qui le souhaitent. Le scénario le plus pessimiste demeure toutefois possible en cas de non réalisation des scénarios fédéraux si le scénario actuel ne résolve pas la crise politique actuelle, une « union économique européenne »Almost sixty years that the European Union began with six members’ State to twenty seven now. At the same time, each member gets involved in different step of the construction of EU, but not with the same commitments: Schengen agreement with twenty three members, Euro zone with seventeen, close European cooperation or partnerships between few countries. In the context of globalization, current crisis (public debts) and crisis coming (Global warming), legal problems raised by the coexistence of a common market, national law and a new European law, what will Europe’s future be in 2015 and 2030? Two scenarios could probably exist in 2015. The first one, “multy-dimensional geometry”, concern a federation of a few members’State, three major countries (Germany, France and Italy) and a group of four little countries (Benelux and Austria). The second one is the current one, the European Union handled by the Lisbonn Treaty, but it doesn’t seem to be the most appropriate for solve the crisis. To face the public debt crisis and the legal problems, the scenario “multy-dimensional geometry” is able to increase the capacity to act on behalf of the federation most than the nations and the European institutions are able to do today (legal, monetary and budgetary policies). In 2030, it would be desirable if scenario “federation for most of the members’State of EU” will succeed. But the scenario of a “free exchange zone in Europe” is not excluded in the case of solutions are not found to solve the crisis

Full textAbstract:
I raggi X, a partire dalla loro scoperta, avvenuta nel 1895 ad opera di Wilhelm Conrad Röntgen, si sono rivelati un potentissimo mezzo per lo studio della materia. In particolare in campo medico hanno permesso la nascita della diagnostica per immagini che, parallelamente allo sviluppo delle tecnologie, è diventata un mezzo imprescindibile per lo studio delle patologie. Negli ultimi decenni molti studi sono stati compiuti in particolare sui vantaggi dell’utilizzo nell’imaging di raggi X monocromatici in sostituzione dell’usuale radiazione policromatica. Con il seguente elaborato si ha l’intento di fornire un quadro generale sulla fisica dei raggi X, sulla loro interazione con la materia e sugli attuali metodi di produzione di fasci monocromatici e quasi-monocromatici, con particolare attenzione all'utilizzo su vasta scala. Sono state infine trattate le principali applicazioni della radiazione monocromatica e quasi-monocromatica nelle tecniche di imaging medico.
