Staigios kūdikio mirties sindromo diagnostika ir etiopatogenezė taikant šiuolaikinius metodus išlieka ribota ir net iki 0,5% mirties priežasčių nepavyksta nustatyti, atsakoma ne į visus klausimus susijusius su sindromo išsivystymu ir diagnoze. Viena iš šiuolaikinių metodų perspektyvų yra imunohistocheminių bei molekulinių metodų taikymas diagnozės patvirtinimui arba atmetimui. Minėti tyrimai yra labai svarbūs priežastinių ryšių nustatymui ir etiopatogenezės pagrindimui. Medžiagų apykaitos sutrikimai, tokie kaip glikogenozės I tipo liga – viena iš aktualiausių ir dažniausiai pasitaikančių, tačiau mažiausiai ištyrinėtų ligų.
Darbo tikslas diagnozuoti glikogenozės I tipo atvejį taikant naujausias imunohistocheminių bei molekulinių tyrimų metodologijas. Tyrime naudojama naujausia parafine įlietų audinių technologija, audiniai įvertinti histologiškai, atliktos imunohistocheminės reakcijos. Iš parafine įlietų audinių išskirta DNR, kokybė įvertinta atlikus spektrofotometrinį tyrimą ir elektroforezę gelyje. Išskyrus DNR iš širdies ir kepenų buvo atlikta polimerazės grandininė reakcija naudojant tikslinius glikogenozės I tipo pradmenis.

One of the applicable methods and perspectives for diagnosis rejection or approval are immunohistochemistry analysis and molecular methods. A very important determination of causal links and proof of etiopathogenesis are very important and possible only after the already mentioned tests. Metabolic disorders, especially glycogenosis type I disease - one of the sorest and the most common, but least-studied cases. The aim of this study is to diagnose glycogenosis type I using the latest immunohistochemistry and molecular methods. The latest technology of paraffin embedded tissue was used in the study, tissues were evaluated histologically, immunohistochemical reaction was carried-out. DNA was extracted from paraffin embedded tissues, quality was measured by spectrophotometric analysis and gel electrophoresis. Using the heart and liver - DNA polymerase chain reaction was performed using targeted glycogenosis type I primers. The results showed an increase of glycogen in the liver. Pancreas, heart, adrenal hypertrophy and hyperplasia were detected in histological samples. During immunohistochemical study an accumulation of glycogen in pancreas cells was observed. Using glucose-6-phosphatase PCR markers of glycogenosis could not be confirmed. Hypotheses for further... [to full text]

Full textAbstract:
A concept is established for adaptive vibration control of shaped alpine skis using smart materials – specifically magnetorheological (MR) fluid. This work presents the motivation behind the concept and the work to verify its viability, technically and commercially. Research is reviewed, relevant to understanding ski dynamics. Literature on smart materials is similarly researched and presented to establish understanding of the use of the technology for dynamic control. The influence of geometry, materials and construction on ski dynamics is presented. Conventional vibration control techniques and their influence on the dynamic control of modern alpine skis are explained. A review of the boundary conditions used in modelling ski dynamics is presented and the influence of skier position and environmental conditions are discussed. Application of smart technology in skis are presented with reference to a shape memory alloy concept and commercially available piezo-systems. Procedures for quantifying the physical characteristics of a ski are discussed and a custom-built laboratory rig is used to test skis under controlled, repeatable conditions. Results from static and dynamic laboratory tests on skis are used to perform system analysis, with reference to technical literature. Analysis of the signal generated by the moving ski during skiing (i.e. signal analysis) is carried out on results from field-tests of instrumental skis. The technical objectives and perceived benefits of adaptive vibration control of skies with MR fluid are examined and technical and commercial system constraints are identified. Results are presented from laboratory tests investigating fore-body vibration control on a concept demonstrator, comprising a MR fluid damper integrated on a simplified ski-like structure. Subsequent analysis is carried out to review the technical and commercial viability of the concept.

Full textAbstract:
Skiing is a fast and competitive sport where skiers must push their performance limit to win medals, the di↵erence can be within hundreds of a second. Therefore, technical improvements are essential for assisting in the skier’s improvement. This thesis project is a joint project between KTH and the Swedish Ski Association and Swedish Ski Team with the purpose of obtaining a better understanding of the structural properties of alpine skis, aiming to improve the individual selection process of skis for the Swedish World Cup Skiers. The goal of the project is to develop and evaluate a method to characterize alpine skis in form of two main structural properties related to the ski characteristics, bending and torsion sti↵ness. An optical measurement device and image post-processing and analysis is used to determine the deflection and twist of skis, which are used to determine the bending and torsional sti↵ness. The method provides, a structural property variation over the whole ski length compared to the existing ISO standard where only a spring coefficient of the skis main parts is determined, which is insufficient for a good over all comparison. The method could be further used in several aspects to help the Swedish World Cup skiers win more medals. It can be used to help in the selection process of new skis for the next season where an objective comparison between models can be done, as oppose to today when the selection process is highly subjective. Skiers usually vary the ski plate constellation and the method could help skiers with their race preparations, like changing the constellation of the ski plate to optimize the sti↵ness for a specific race condition with engineering knowledge rather than just trusting the feeling. The use of this method can reduce the number of ski tests performed by the skier, thus leaving more time for practice. Testing skis in a laboratory environment also increases objectivity in testing and can therefore give the Swedish Ski Association and Swedish skiers a competitive advantage in upcoming competitions.

La première partie établit la caractérisation d'une section de poutre composite, de forme et de constitution quelconques, du point de vue de ses propriétés élastiques. La condition d'annulation de la densité linéique de travail virtuel, qui détermine rigoureusement l'état d'équilibre de la section, est réalisée de manière approchée par une méthode d'éléments finis. Elle conduit à la définition d'une matrice de rigidité de section, caractéristique de tous les types de sollicitations et de leurs couplages éventuels. Une matrice de raideur d'élément de poutre tridimensionnel en est déduite. La seconde partie est consacrée à l'étude du comportement de telles poutres en présence de liaisons unilatérales. Les conditions de liaison/séparation sont examinées au cours d'un processus itératif basé sur une méthode de gradient conjugué modifiée. Le calcul détermine les zones de contact entre la poutre et un massif élastique, ainsi que la pression de contact. Enfin, les résultats de diverses applications sont présentés. La première concerne un ski alpin en appui sur la neige, soit, à plat, par l'intermédiaire de la semelle, soit sur la carre. La seconde décrit l'évolution du champ de pression sous un ski nordique au cours des différentes phases du mouvement. Des corrélations sont dégagées entre ces résultats, des résultats de laboratoire et les observations d'essayeurs.

Att vårda sina relationer har för företag blivit betydligt viktigare och mer tid har lagts på utvecklandet av relationsmarknadsföring. Hur dessa relationer skapas och vad som gör att de utvecklas och bibehålls har dessutom varit i forskarnas blickfång. I dagens forskning åtskiljs relationer mellan företag samt relationer mellan företag och konsumenter.
Syftet med denna uppsats är att, genom att studera och analysera Hendryx Skis Industries konsumentrelationer, undersöka huruvida Holmlunds relationsmodell, som utvecklats för att studera relationer mellan företag, även är tillämpbar för att undersöka relationer mellan företag och konsumenter.
Med skidföretaget Hendryx Skis Industries som fallstudie analyserades det insamlade materialet med hjälp av tre dimensioner; en teknisk, en social och en ekonomisk. Tydligt kan sägas att den tekniska och sociala dimensionen kan identifieras som viktiga och väl fungerande mätinstrument. Däremot bör bättre anpassade ekonomiska variabler utarbetas för att på bästa sätt kunna analysera kundrelationer även inom denna dimension.

Dissertação para obtenção do Grau de Mestre em Engenharia InformáticaThe volume of digital information is increasingly larger and even though organiza-tions are making more of this information available, without the proper tools users have great difficulties in retrieving documents about subjects of interest. Good infor-mation retrieval mechanisms are crucial for answering user information needs. Nowadays, search engines are unavoidable - they are an essential feature in docu-ment management systems. However, achieving good relevancy is a difficult problem particularly when dealing with specific technical domains where vocabulary mismatch problems can be prejudicial. Numerous research works found that exploiting the lexi-cal or semantic relations of terms in a collection attenuates this problem. In this dissertation, we aim to improve search results and user experience by inves-tigating the use of potentially connected Web vocabularies in information retrieval en-gines. In the context of open Web-based SKOS vocabularies we propose a query expan-sion framework implemented in a widely used IR system (Lucene/Solr), and evaluated using standard IR evaluation datasets. The components described in this thesis were applied in the development of a new search system that was integrated with a rapid applications development tool in the context of an internship at Quidgest S.A.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2008."June 2008."
At the request of K2 Sports, in Seattle, Washington, a machine was constructed to measure the base profile of skis and snowboards. The measurements to be taken included overall length, running surface length, locations of the contact points, tip and tail height, and maximum camber height, each of these values having a strong effect on the performance of the ski or snowboard. Parts from two existing non-functioning machines, one acquired in K2 Sports' acquisition of Line Skis, and the other constructed by previous interns, were used to construct the new machine. The new machine was designed to function by placing the ski on two parallel flat surfaces on the Line machine's frame with a gap between for a laser sensor. The guide rail and cart system from the past interns' machine was retrofitted with the motor and controls of the Line machine and a new drive belt to carry the sensor along the length of the ski. A Micro Epsilon optoNCDT 1401-200 laser sensor having a resolution of 100 pm and a data acquisition rate of 1kHz was used to acquire the height data as the sensor moved at a controlled speed along the entire length of the ski. Data was recorded using Micro Epsilon's ild1401 Tool software, and processed automatically through a National Instruments LabVIEW Virtual Instrument. The machine was presented to K2 engineers on August 15, 2007. It accurately records the desired measurements which are helpful in predicting the performance effects of design changes to the ski or snowboard. The machine remains in daily use.

Full textAbstract:
Flow Motion Technology AB has previously developed a technology to improve hockey skates and inlines. The technology called Flow Motion Technology (FMT) is utilizing the smooth and effective rolling motion of a human footstep, and has proven to be very successful after implementation in both hockey skates and inlines. Flow Motion Technology AB has interest in investigating whether the technology can be implemented in other sports applications, which this thesis project concerns. The project examines the implementation of FMT in the alpine skiing segment. The purpose is to provide Flow Motion Technology AB with a foundation for evaluating the potential of investing further in the development of FMT applied in alpine skiing. FMT is implemented in a feature positioned between ski and binding of most alpine race skis, commonly called a race plate. The work is divided into two parts; The first part covers the development and manufacturing of a prototype along with detailed description of the procedures and methods used. The second part is about the tests of the prototype’s vibration-damping properties carried out in laboratory environment along with analysis of the results. Initial field tests are also carried out followed by fundamental analysis. An existing plate intended for competition use is tested in parallel with the prototype and is used as a reference when analyzing the results. The results show that the ski equipped with the FMT plate dampened vibrations on an average of 27 % faster than the reference plate. Measurements was compiled for three damping intervals specified for the tests performed in laboratory. A statistically significant difference in all three cases was obtained. The measured maximum amplitude of the acceleration in the vibrations was also significantly lower for the ski implemented with the FMT plate compared to the reference plate. The eigen frequencies of the ski measured in laboratory were not significantly affected if the ski was fitted with the FMT plate or the reference plate. The eigen frequencies measured in field generally corresponded to the measured in laboratory, with the difference that they were offset on an average of 7 Hz higher in field.Flow Motion Technology AB har tidigare utvecklat en teknologi för att förbättra hockeyskridskor och inlines. Teknologin kallad Flow Motion Technology (FMT) utnyttjar den naturliga och effektiva rullande rörelse i en människas fotsteg, och har efter implementation i hockeyskridskor och inlines visat sig vara framgångsrik. Flow Motion Technology AB vill undersöka om denna teknologi kan implementeras i andra idrottssammanhang för att utvärdera möjligheter att bredda företagets affärsområde. Detta examensarbete är en del av denna undersökning, och i denna rapport beskrivs implementationen av FMT i segmentet alpinskidåkning. Syftet med projektet är att förse Flow Motion Technology AB med underlag för att utvärdera lönsamheten i att investera mer i utvecklingen av FMT riktad mot alpinskidåkning. FMT implementeras i projektet i en raceplatta, en komponent monterad mellan skida och bindning. Arbetet är uppdelat i två delar; utveckling och tillverkning av en funktionsprototyp med detaljerad beskrivning av tillvägagångssätt och metoder, samt tester av prototypens vibrationsdämpande prestanda i labbmiljö med tillhörande analys av resultat. Initiala tester utförs även i fält med enklare analys av resultat. En befintlig bindningsplatta avsedd för tävling testas parallellt med den utvecklade plattan och används som referens vid analys av resultaten. Resultaten visar att plattan implementerad med FMT dämpade en skidas vibrationer i genomsnitt 27 % snabbare än vad referensplattan gjorde vid de tre dämpningsintervall som specificerats för testen i labbmiljö. En statistiskt signifikant skillnad i alla tre fall. Den uppmätta maxamplituden för accelerationen i vibrationerna var även statistiskt signifikant lägre för skidan implementerad med FMT jämfört med referensplattan. Egenfrekvenserna uppmätta i labb påverkades inte nämnvärt om skidan var monterad med FMT-plattan eller referensplattan. De egenfrekvenser som uppmättes i fält motsvarade generellt de som uppmättes i labb med skillnaden att de var förskjutna till att i genomsnitt vara 7 Hz högre.

Full textAbstract:
Les achats en ligne sont de plus en plus populaires auprès de la population, mais les skieurs sont encore réticents à acheter leurs skis alpins en ligne. La vente en ligne de skis est entre autres limitée par le manque d'informations disponibles sur les skis et l’absence de bon conseils comme ceux que peuvent prodiguer les vendeurs souvent spécialisés dans leur domaine.
Pour augmenter la quantité d’information disponible sur les skis, un banc de test a été conçu pour caractériser les propriétés mécaniques et la géométrie des skis. Les propriétés mesurées sont les distributions de rigidité en flexion et en torsion, la cambrure et la largeur. Ce banc de test, en plus d’être très rapide (3 minutes d’utilisation), permet d’obtenir une grande précision et une répétabilité avec une erreur inférieure à 5%.
Pour ce qui est de prodiguer de bons conseils, la première étape est de comprendre l’influence de ces propriétés sur les performances des skis. Pour ce faire, de nombreuses études ont tenté de prédire les relations entre des critères de performance du ski sur la neige et les propriétés des skis en utilisant des coefficients de corrélation de Pearson ou de Spearman en deux dimensions [1, 2, 3, 4]. Ces modèles offrent des résultats mitigés en raison de la nature complexe du ski. Pour tenir compte de cette complexité, cette étude propose d'utiliser des analyses multivariées pour développer des outils de recommandation. Un premier outil prédit le niveau optimal de rigidité en flexion et en torsion des skis pour un profil de skieur donné et le deuxième outil prédit les performances sur la neige des skis à partir de ces propriétés mécaniques.
Ces outils sont basés sur les résultats de tests sur neige avec 23 participants, 12 paires de skis géométriquement identiques mais avec des rigidités en flexion et en torsion différentes et un questionnaire. Ce questionnaire identifie le profil du skieur et les impressions sur la neige de chaque skieur sur chaque ski selon 8 critères de performance. De fortes relations linéaires multivariées ont été trouvées (jusqu'à R^2 = 0,96) entre le profil des skieurs et les propriétés mécaniques de leur ski préféré. De même, des relations multivariées linéaires fortes ont été trouvées entre la performance du ski et ses propriétés. Dans les deux cas, en comparant le coefficient de détermination ajusté, les modèles linéaires multivariés dépassent de manière significative les modèles en deux dimensions basés sur les coefficients de corrélation de Pearson. Cela confirme la nature complexe du ski. L'intégration future de l'effet de la géométrie et des conditions de neige à cette analyse permettra de créer un outil de recommandation complet et utile pour le commerce électronique et la vente au détail.

Full textAbstract:
L'étude tente de rendre compte de l'évolution de l'activité ski tant au niveau des changements du matériel que de l'enseignement et, de l'adaptation que cela engendre du point de vue des sujets lors de diverses situations constituant des virages dans un test. Adossée à la théorie des champs conceptuels de Vergnaud, elle prend la forme d'une étude des conceptualisations implicites dans les "schèmes obstacles". Tel qu'il est dit par Vergnaud, le shème apparaît comme l'organe de l'action motrice du fait qu'il comporte toutes les composantes indispensables de l'organisation et à l'exécution de celle-ci. Les modalités de l'activation et du fonctionnement du schème permettent de considérer que connaissance, information et action sont fonctionnellement indissociables. Le développement du schème obstacle est celui de la "connaissance antérieure" : il s'accompagne d'une extension de la classe des situations pour lesquelles le sujet doit opérer des modifications suite au passage des skis traditionnels aux skis paraboliques. Le schème obstacle apparaît comme une résistance de la part du sujet par rapport à la nouveauté. Le sujet se sert préférentiellement de ses acquis des apprentissages précédents, mais, il a aussi des représentations envers la nouvelle pratique. Cette étude fait ressortir les éléments récurrents qui font obstacles ainsi que les représentations justes ou fausses des sujets. D'autres part, il faut garder en mémoire que les sujets ont un shème qu'ils doivent rendre de plus en plus performant pour aboutir à la nouvelle techique. Certains y arriveront, d'autres nonThe study seeks to take into account the evolution of skiing in relation to changes in equipment, as well as teaching methods and the adaptation that will result from the point of view of subjects in various situations that constitute test conditions. Supported by the theory of Vergnaud's conceptual fields, it takes the form of a study of conceptualisations implicit in "obstacle schemes". According to Vergnaud, the scheme resembles the motor action organ, in as much as it is made up of all the vital components for the organisation and function of the latter. The methods of activation and function of the scheme give credence to the belief that knowledge, information and action are inextricably linked. The development of the obstacle scheme is that of "prior knowledge" ; it becomes part of an extension of the class situation where the subject must make changes following the progression from traditional to parabolic skis. The obstacle scheme appears as resistance from the subject's part in relation to new sitations. The subject prefers to make use of previously acquired knowledge, but makes attempts at new practice. This study highlights the recurring elements, which make up the obstacles as well as the correct or incorrect manoeuvres of subjects. Furthermore, it must be remembered that the subject has a scheme which must be constantly perfected in order to achive new techniques. Some will achieve this, other will not

Full textAbstract:
The aim of this master’s thesis is to study in what ways an audience who does not identify as heterosexual reflect over the Norwegian TV-show SKAM’s non-heterosexual representations. The research was carried out through five focus group interviews with thirteen people and used theories on identification, stereotypes and the media together with queer theory and intersectional theories. The study’s interviews show that SKAM gives different opportunities for identification. The respondents all identifies with ways the show deals with coming out and how the process is shaped by subtle forms homophobia. The show’s focus on heteronormativity and internalized homophobia is also strongly identified with and considered to be skilfully told. How Isak and Even’s relationship is portrayed is appreciated as well, which was a source for positive identification. The character Eskild was also brought up as a clever way to show how stereotypical representations can be used in a positive and inspiring way. The show’s general lack of non-heterosexual characters and their portrayal as all white, cis, middle class men was critiqued, as well as how the show handled fetishzation of non-heterosexual relationships. It becomes clear from the interviews how the respondents negotiate the non-heterosexual representations in SKAM in order to find identification, which helps them validate their own sexual identities. Moreover, the study also shows how representations, how they affect and regulate people’s social lives and identities, can be better understood by favouring not only the media but the viewers as well.

Les propriétés mécaniques d’un ski alpin, dont sa longueur, le profil des carres (aussi nommé le profil de largeur), le profil de cambrure et les distributions de rigidités en flexion et en torsion, sont des facteurs déterminants de sa performance. Un des aspects essentiels de cette performance est la stabilité directionnelle du ski en virage; il est généralement accepté qu’un ski pour experts nécessitera une plus grande stabilité qu’un ski pour skieurs débutants ou intermédiaires. Cependant, il n’existe aucune étude sur l’étendue du niveau de stabilité que présentent les différents skis alpins modernes. Ce projet a pour but d’identifier cette étendue du niveau de stabilité par le biais de simulations numériques, ainsi que d’explorer l’effet des différentes propriétés mécaniques sur la stabilité d’un ski. Afin d’y parvenir, une nouvelle méthode a été développée afin de mesurer les distributions de rigidités en flexion et en torsion et les profils de cambrure et des carres d’un ski en moins de 5 minutes avec une précision d’environ 5%. Cette méthode a été utilisée pour mesurer les propriétés mécaniques de 179 skis de différents types (skis de courses, skis récréatifs, skis de haute randonnée, skis de neige poudreuse, etc.), soit un échantillon varié de la gamme entière des skis alpins commercialement disponibles. Un outil de simulation numérique a été développé et utilisé afin d’évaluer la stabilité de ces skis. Un modèle simple pour rapidement estimer la stabilité a été développé et est fortement corrélé avec les niveaux de stabilité évalués par le biais des simulations. Ce modèle simple permet d’estimer la stabilité d’un ski sans avoir recours à des simulations ou des essais expérimentaux. Ce modèle simple permet aussi de comprendre l’effet des différentes propriétés mécaniques d’un ski sur son niveau de stabilité.

More than 4,000,000 radial teleseismic traces from about 8,000 events (mb >= 5.8) between 1990 and 2015, globally recorded by one or more of a total ~27,000 receivers, were collected from IRIS-DMC. All of the traces were automatically band-pass filtered (10s to 50s), rotated, clustered, deconvoluted, and finally migrated to structural reflectivity profiles using reference wavespeeds according to the iasp91 model. We compare the 2D and 3D imaging results beneath the Pacific subduction zones and the non-subducting regions, including the southeastern Pacific and Hawaii, focusing on the positive velocity contrast above the CMB that might delineate the D" discontinuity. We observe broad zones of scatter surfaces, which may indicate multiple-interface post-perovskite phase transitions caused by compositionally differentiated subducted lithosphere. Furthermore, we observe a sharp change in the proposed multiple-interface structure regarding the total number of positive interfaces, the intervals, and the overall pattern of the anomalies from the subduction zones to the non-subducting regions. Such structural complexity implies: (1) the presence of old (at least 180 Ma) subducted material layer of either continental or oceanic lithosphere under the whole Pacific Ocean; and (2) spatial variations in iron, magnesium, and silica components in the subducted lithosphere. Understanding the possible relationship between observed complexity and composition requires further interdisciplinary research.

Full textAbstract:
As alpine skiing is becoming more and more popular the need for sustainable products are increasing in order to enable great skiing and snowy winters in the future. The ski industry is unfortunately far behind many other industries when it comes to sustainability and the shift towards sustainable skis is going slow. Norse Skis is a unique ski manufacturer as they have a sustainable profile and are always in the lookout for new possibilities to take that forward. The goal in this master thesis project is to develop a pair of sustainable skis that will widen Norse Skis’ product catalog. The project was conducted in collaboration with Norse Skis as a master thesis project within the degree of Industrial Design Engineering at Luleå University of Technology. During the development of the skis, the user-centered design process Design Thinking Process was used. The process was divided into three phases; Inspiration, Ideation, and Implementation. During the design process, most of the energy was put on creating a ski that meets the user needs and is as sustainable as possible. Through constant dialog with the users, feedback and evaluation were gained to customize the product to the needs and opinions of the users. To develop skis that are as sustainable as possible, the project has had its base in the three aspects of sustainability; ecological, economic, and social, which are defined in the Brundtland report (World Commission on Environment and Development, 1987). At the beginning of the project, a deep understanding of alpine skis and alpine skiing was gathered. This was followed by a thorough examination of the users through surveys and user observations. It was identified that the users spent most of their time skiing on the piste, but had a vision of being an off-piste skier. This led to the conclusion of designing a ski that is high performing on-piste but also gives the user the possibility to great off-piste skiing. In a benchmarking, Norse Skis’ current skis were compared to their competitors’ to identify Norse Skis’ strengths and what could be improved. When an understanding of the product and the users was gained, the project proceeded into the ideation phase. In the ideation phase solutions on lengths, shapes, names, colors, graphics, and materials were created. Through user surveys, three concepts were created which eventually resulted in one final design. The project result is a pair of 90 mm wide skis with focus on sustainability that are high performing and playful in the piste while providing a nice off-piste ride as well. From the social aspect, they are created with the skier in mind instead of either men, women, or some specific age group. By using materials that are more environmentally friendly than what is used in Norse Skis’ skis today and that either have the same or lower price, the skis are more sustainable from both an ecologic and economic perspective. The design has been approved by the users which led to the recommendation of broadening Norse Skis’ current product catalog with the ski that was the result of this master thesis project.Samtidigt som skidåkning blir mer och mer populärt för var dag som går så ökar behovet av hållbara produkter som möjliggör framtida snöiga vintrar och bra skidåkning. Tyvärr ligger dagens skidtillverkare långt bakom många andra branscher när det kommer till hållbarhet och skiftet mot hållbara skidor går trögt. Norse Skis är en unik skidtillverkare då de har en hållbar profil och ständigt letar efter möjligheter att komma ännu längre fram i utvecklingen. Målet i detta examensarbete är att utveckla ett par hållbara skidor som kan bredda Norse Skis produktkatalog. Projektet utfördes i samarbete med Norse Skis som ett examensarbete på Civilingenjör Teknisk Design med inriktning produktdesign vid Luleå Tekniska Universitet. Under utvecklingen av skidorna användes den användarcentrerade designprocessen Design Thinking Process som är uppdelad i tre faser; Inspiration, Ideation, och Implementation. Under designprocessen låg fokus på att skapa en skida som uppfyller användarbehoven och samtidigt är så hållbar som möjligt. Genom att hela tiden återkoppla med användarna för utvärdering och feedback kunde produkten anpassas efter deras behov och tycke. För att utveckla en så hållbara skida som möjligt har projektet utgått från de tre perspektiven av hållbarhet; ekologisk, ekonomisk, och social som identifieras i Brundtlandsrapporten (World Commission on Environment and Development, 1987). I projektets startskede införskaffades en djup förståelse alpina skidor och alpin skidåkning. Detta följdes av djupdykning i användaren genom enkäter och användarobservationer. Det identifierades att användaren spenderar mest tid i pisten, men har en vision om att vara en off-pist åkare. Detta ledde fram till slutsatsen att designa en skida som är högpresterande i pisten med också ger användaren möjlighet till bra off-pist åkning. I en benchmarking jämfördes sedan Norse Skis nuvarande skidor med konkurrenternas för att identifiera Norse Skis styrkor och vad som kunde göras bättre. När en förståelse över produkten och användarna skapats gick projektet in i idégeneringsfasen. Där skapade olika lösningsförslag på längder, former, namn, färg, grafik, och material. Genom användarundersökningar kunde tre slutkoncept tas fram som slutligen resulterade i ett slutgiligt resultat. Projektresultatet är ett par 90 mm breda skidor med fokus på hållbarhet som är högpresterande och lekfulla i pisten som även ger en härlig åkning utanför. Ur den sociala aspekten är de gjorda för skidåkare istället för enbart män, kvinnor eller någon specifik åldersgrupp. Genom användning av material som är miljövänligare än de som Norse Skis tidigare använt och antingen har samma eller lägre pris så är skidor både hållbarare ur både ett ekologisk och ett ekonomiskt perspektiv. Designen har bekräftats av användarna vilket ledde till att rekommendationen att bredda Norses Skis produktkatalog med skidorna som var resultatet av detta examensarbete.

Full textAbstract:
Die Inzidenz von neurodegenerativen Erkrankungen und Schlaganfällen steigt in Folge der Überalterung der westlichen Gesellschaft immer weiter an. Die Behand-lung von Schlaganfall-, Alzheimer und Parkinsonpatienten ist bisher aber meist unbefriedigend bzw. weitgehend erfolglos. Ein neues Modell in der Schlaganfallforschung wurde daher am Schaf entwickelt. In diesem wird auch der in den letzten zwei Jahrzehnten verstärkt verfolgte zelltherapeutische Ansatz untersucht (BOLTZE et al. 2011, DREYER et al. 2012). Neurale Vorläuferzellen gelten dabei, auf Grund ihrer wichtigen Rolle bei den endogenen Reparaturmechanismen nach einem Schlaganfall, als besonders vielversprechend. Die Gewinnung dieser Zellen für eine autologe Transplantation ist jedoch aufwendig und nur eingeschränkt möglich. Im Vergleich zu Nervengewebe stellt die Haut eine sowohl beim Tier als auch beim Menschen leicht zugängliche und in ausreichendem Maß verfügbare Quelle verschiedener Stamm- und Vorläuferzellen dar. Bei verschiedenen Spezies wurde die Isolation spezieller, dermaler Vorläuferzellen beschrieben, die als skin-derived precursor cells (SKPs) bezeichnet werden. SKPs wiesen dabei ein ähnliches Differenzierungspotential auf wie neurale Vorläuferzellen (TOMA et al. 2001, FERNANDES et al. 2006). Ein Einsatz der SKPs in der Schlaganfalltherapie wäre somit denkbar, muss aber zunächst im Schafmodell erforscht werden. SKPs wurden jedoch noch nicht bei der Spezies Schaf isoliert. Ziel der vorliegenden Arbeit war es daher, ein Isolationsprotokoll für SKPs aus der ovinen Dermis zu etablieren und diese morphologisch und immunzytologisch zu charakterisieren. Im Rahmen dieser Arbeit wurden verschiedene in der Literatur beschriebene Isolati-onsverfahren an ovinen Hautproben getestet und modifiziert. Es wurden verschiedene Körperregionen auf ihre Eignung zur Probenentnahme und zur anschließenden Isolierung untersucht. Des Weiteren wurde der Effekt einer Rasur eine Woche vor Exzision des Hautareals auf die Sphäroidbildung überprüft. Der Einsatz von Enzymen in Kombinationslösungen oder singulär wurde variiert und eine unterschiedlich intensive mechanische Aufbereitung der Proben durchgeführt. Der Erfolg der zwei vielversprechendsten Isolationsprotokolle wurde statistisch validiert. Außerdem wurde der Effekt einer initialen Fibronektinbeschichtung analysiert. Die von den isolierten Zellen gebildeten sphärenartigen Zellaggregate wurden unter morphologischen Gesichtspunkten sechs und neun Wochen nach Isolation ausgewertet. Dabei wurden die Anzahl der Sphäroide/cm², die Größe und die Form berücksichtigt. Des Weiteren erfolgte eine immunzytologische Analyse der Sphäroide mit Fokus auf das in der Literatur beschriebene Expressionsmuster von SKPs und neuralen Vorläuferzellen. Für die Isolation von ovinen SKPs erwies sich die Regio nasofrontalis als das geeignetste Hautareal. Dabei war die Isolation eine Woche nach Rasur des beprobten Areals zuverlässiger als ohne diese. Bei vergleichender Betrachtung der Methoden erwies sich ein enzymatisch orientiertes Isolationsverfahren modifiziert nach FERNANDES und MILLER (2009) als zielführend. Neben einer hohen Anzahl an isolierten Zellen erfolgte in jedem Versuchsdurchgang eine Zusammenlagerung der Zellen in frei flotierenden Aggregaten. Diese waren im Median 70,97 µm groß. Auf Grund ihrer Geometrie ist es korrekter sie als Sphäroide und nicht, wie bei anderen Spezies üblich, als Sphären zu bezeichnen. Eine anfängliche Beschichtung der Zellkulturplatten mit Fibronektin hatte keinen fördernden Effekt auf die Bildung und die Größe der Sphäroide. Lediglich eine anfänglich höhere Proliferationsrate war bemerkbar. Immunzytologisch konnte gezeigt werden, dass in den Sphäroiden eine heterogene Zellpopulation vorlag. Die Sphäroide wurden überwiegend von Zellen gebildet, in denen neben mesenchymalen Markern auch klassische Vorläuferantigene wie Nestin und Sox2 nachgewiesen wurden. Das immunzytologische Expressionsmuster ist damit vergleichbar mit dem von SKPs anderer Spezies. Außerdem wurden in unterschiedlicher Ausprägung Antigene detektiert, die typischerweise in neuralen Vorläuferzellen der ventrikulären und subventrikulären Zone vorkommen. Dies konnte auch in den Positivkontrollen für das ovine Gehirn bestätigt werden. Die Anzahl proliferierender Zellen in den Sphäroiden war relativ gering und die Anzahl an kokultivierter Keratinozyten minimal. Die Zusammenfassung der heterogenen Vorläuferzellpopulation unter dem Begriff skin-derived precursor cells ist auf Grund ihres dermalen Ursprungs und ihrer morphologischen und immunzytologischen Eigenschaften gerechtfertigt. Somit ist es in dieser Arbeit gelungen, zum ersten Mal SKPs aus der ovinen Dermis zu isolieren und über neun Wochen zu kultivieren. Es wurde ein Isolationsprotokoll entwickelt, das eine Sphäroidbildung reproduzierbar ermöglicht und an die Gegebenheiten beim Schaf angepasst ist. Bevor eine autologe Transplantation von diesen SKPs etwa im Schlaganfallmodell am Schaf vorgenommen werden kann, ist eine intensivere Untersuchung der isolierten Zellen etwa mittels PCR durchzuführen und eine fluoreszenzbasierte Zellsortierung der heterogenen Vorläuferzellen zu entwickelnIn consequence of the demographic changes in modern western society, the inci-dence of neurodegenerative diseases and stroke is increasing. Unfortunately, there is still no successful or at least satisfactory treatment available for patients who suffer from stroke Alzheimer’s or Parkinson’s disease. Therefore, a new animal model in stroke research has been established in sheep (BOLTZE et al. 2011, DREYER et al. 2012). First cell therapy studies have already been performed in this model. Especially neural precursor cells seem to be promising as they play an important role in endogenous repair processes in the brain after stroke. However, the extraction of these cells prior to an autologous transplantation is elaborate and of limited success. Compared to neural tissue, skin is an easily accessible and sufficiently available source of a variety of stem and precursor cells in animals as well as in humans. Thus, the isolation of a specific type of dermal precursor cells, called skin-derived precursor cells (SKPs), seems to be easier compared to neural precursor cells and in vitro SKPs are capable of neural differentiation as well (TOMA et al. 2001, FERNANDES et al. 2006). According to these findings, a therapeutic application of SKPs after stroke seems to be promising. Prior to that, however, intensive studies in the ovine stroke model are necessary. Thus, SKPs have to be isolated from the dermis of sheep for an autologous transplantation. Therefore, the aim of this dissertation has been the establishment of an optimal isolation protocol for SKPs from the ovine dermis as well as the morphological and by immunocytochemical characterisation of those cells. Within this study, several previously described isolation protocols were modified for ovine skin. Skin samples were taken from several body regions to assess the local suitability for excision and isolation. Additionally, the effect of shaving the areas one week before sampling on spheroid forming was tested. A variety of enzymes was used alone and in combination. Furthermore, the effectiveness of an isolation protocol using enhanced mechanical treatment was analysed. The two most promising protocols were evaluated statistically and compared to each other. In these experiments, the influence of an initial fibronectin coating was determined as well. The isolated cells formed spheroids, which were assessed after six and nine weeks of cultivation considering the amount of spheroids per cm², their size and form. Moreover, immunocytochemical tests were conducted, focusing on expression patterns described for SKPs and neural precursor cells. According to these experiments, it is advisable to take skin samples from the naso-frontal region one week after shaving. Comparing all tested protocols, a predominantly enzymatic isolation protocol modified according to FERNANDES and MILLER (2009) was most successful. A high cell yield was achieved and free-floating spheroids formed spontaneously in all test runs. The median diameter of these spheroids was 70.97 µm. Due to their three-dimensional shape, it is more correct to use the term “spheroid” instead of the commonly used term “sphere”. Growing the isolated cells initially on fibronectin coated culture plates does not support both formation and size of the spheroids. Only a higher cell proliferation at the beginning of cultivation can be noticed. Immunocytochemical assays demonstrated that the formed spheroids consisted of a heterologous cell population. Besides mesenchymal antigens the cells in the spheroids expressed characteristic antigens of precursor cells, like Nestin and Sox2. Thus, the immunocytochemical expression pattern is comparable to SKPs isolated from other species. Furthermore, common markers of neural precursor cells of the ventricular and subventricular zone, whose existence in the ovine brain was also proven in this study, were detected in the spheroid forming cells. There were only a few proliferating cells and a minimal amount of keratinocytes in the spheroids. Due to the dermal origin and the given morphological and immunocytochemical characteristics, the heterogeneous cell population can be addressed by the term “skin-derived precursor cells”. In conclusion, in this study ovine SKPs were isolated for the first time and cultured successfully over nine weeks. An isolation protocol was established, which guarantees reproducible formation of spheroids in cell isolates from ovine dermis. Further intensive examinations of the isolated cells, for example using PCR, have to be conducted before SKPs can be applied in autologous transplantation in the ovine stroke model. Additionally, the usage of fluorescence-activated cell sorting of the heterogeneous precursor cells should be considered

Dissertação para obtencão do Grau de Mestre
em Engenharia CivilPretende-se, com a presente dissertação, apresentar um contributo para o estudo de escoamentos fluviais, nomeadamente na previsão de alturas de água, velocidades e tensões de arrastamento, em situação de cheia. Nestas situações, o leito principal não tem capacidade de vazão para o caudal e transborda, passando o escoamento a processar-se simultaneamente no leito principal e no leito de cheia. O escoamento passa, então, a ser efectuado em secção composta, o que origina o aparecimento de estruturas de escoamento que provocam alterações no mesmo. O modelo analítico de Shiono e Knight (SKM) requer três parâmetros de calibração, f,λ e,Ƭ referentes, respectivamente, à resistência de fundo, à viscosidade turbulenta e às correntes secundárias. Estes três parâmetros de calibração, quando correctamente definidos, permitem ao modelo obter uma distribuição da velocidade e da tensão de arrastamento bastante próxima da real, o que por sua vez, permitem obter uma estimativa bastante razoável da capacidade de vazão do canal. Nesta dissertação calibraram-se, a partir de dados experimentais já existentes, os parâmetros do modelo SKM, para seis séries de dados diferentes, correspondentes a seis alturas relativas. Após o cálculo dos parâmetros de calibração foi necessário verificar a sua validade, comparando as distribuições de velocidade longitudinal média em profundidade dada pelo modelo com os parâmetros calibrados com a velocidade longitudinal média em profundidade, calculada directamente a partir dos dados experimentais. Foi também estudado, mais aprofundadamente o parâmetro das correntes secundárias, sendo que se demonstrou que a obtenção do valor deste parâmetro a partir de dados experimentais de velocidade longitudinal e transversal não era de fácil concretização. Foram, ainda, realizados estudos para melhor se compreender o comportamento do escoamento que se basearam na equação da conservação da quantidade de movimento do escoamento.

Full textAbstract:
La situation du marché du ski alpin en Amérique du Nord et en Europe est face à un environnement concurrentiel très fort. Sa situation stagnante a pour conséquence de regrouper les marques en grands groupes internationaux qui ont tendance à uniformiser l'offre dans le but de pallier le manque de croissance. Parallèlement, ce marché du ski évolue au sein des changements socioculturels de la pratique sportive. Les femmes, étant au coeur de ces évolutions, constituent donc un marché substantiel pour les marques de sports d'hiver. L'objectif de notre recherche est d'évaluer l'impact des variables de culture et de genre sur le comportement d'achat et sur la perception de la marque Rossignol. L'étude de la littérature en marketing interculturelle fait apparaître deux tendances : la première met en avant la globalisation de la demande et donc de l'offre et la seconde, à l'inverse, met en exergue leur différenciation face aux spécificités culturelles. Nous constatons que la littérature en marketing ne traite pas simultanément de l'aspect culturel et de celui du genre. Les hypothèses ont été rédigées afin de mettre en évidence la non-homogénéité du marché du ski alpin et de démontrer qu'une stratégie marketing internationale standardisée n'est pas une solution efficace pour pallier le manque de croissance du marché. La méthodologie présidant à la validation des hypothèses de recherche repose sur la mise en place d'une analyse qualitative. Cette étude a permis de souligner qu'il était indispensable pour la marque Rossignol de tenir compte à la fois des différences culturelles, des caractéristiques des femmes, de son image de marque statutaire et de la situation du marché, afin d'être à même de proposer une stratégie internationale optimisée. Des préconisations sont proposées pour ces quatre contraintes, afin de mettre en oeuvre cette stratégieNorth America and Europe are currently facing a highly competitive alpine ski market. Subsequently, smaller brands are being absorbed into larger multinational companies which in turn are standardizing their product lines to compensate for the lack of growth in this sluggish market. Meanwhile, the alpine ski market is evolving within certain socio-cultural trends, at the heart of which we find women and sports. Women can therefore be considered a significant market for alpine ski manufacturers. The object of this study is to evaluate the impact of culture and gender on consumer behavior as well as perception of the Rossignol brand. Two major trends are revealed throughout intercultural marketing literature : the first points out a normalized demand and therefore a similar offer ; on the other hand, the second trend highlights differences based on specific cultural diversity. Marketing literature doesn't seem to deal with cultural and gender aspects simultaneously. The premise of this thesis is the non homogeneity of the alpine ski market thus demonstrating that a standardized international marketing strategy is not the correct solution to counter the market's lack of growth. The methods used to validate this premise are based on qualitative analyses. These study demonstate how it's necessary for the brand to take into account cultural differences, women characteristics, a statuary brand image and the market situation in order to purpose an optimal marketing stategy. Recommendations are define corresponding to the last four constraints in order to set up the strategy

Syftet med detta arbete är att ta fram den ultimata träkärnan utefter uppspaltade önskemål på egenskaper i ett par allmountainskidor med nordiska träslag. Studien är deskriptiv och kvantitativ då den syftar till att mäta förändringsgraden under påverkan på träslagen. För att få in data till mina frågeställningar har tester genomförts som genererar datainsamling. En förundersökning gjordes med intervjuer för att få fram ett mer specificerat underlag för att konstruera vilken metod jag skulle ha i det slutgiltiga arbetet. Resultatet av studien visade att träslaget bok hade de bästa egenskaperna vad gäller böjhållfasthet. Ask hade de bästa egenskaperna när det kom till testerna på vridstyvhet. Det negativa med dessa träslag är att de är för tunga. Det lättaste träslaget av de som var med i testerna var poppel. Därför har jag valt att i den slutgiltiga träkärnan kombinera träslag. Två olika förslag har tagits fram. Den ena med en kombination av bok och poppel, den andra med ask och poppel. Den första ger en förhållandevis lätt skida med bra böjhållfasthet. Den andra en lätt skida med bra vridstyvhet. Dessa två träkärnor kommer användas i byggandet av mina skidor och testas på berget.The purpose of this work is to produce the most optimal wood core with the desired requirements in an all-mountain ski using Scandinavian wood. The study is descriptive and quantitative as it aims to measure the rate of change under the influence of wood species. In order to collect data for my research questions, tests have been carried out which generate data collection. A preliminary investigation was done with interviews to obtain a more detailed basis for constructing the method I would use in the final work. The results of the study showed that the wood type beech had the best results in terms of flexural strength. Ash had the best results when it came to tests on torsional rigidity. The down side of these woods is that they are too heavy. The lightest wood species of those involved in the tests was poplar. Therefore, I have chosen to combine species in the final wood core. Two different suggestions have been developed. One with a combination of beech and poplar, the other one with ash and poplar. The first provides a relatively light ski with good flexural strength. The second produced a light ski with good torsional rigidity. These two wood cores will be used in the construction of my skis and tested on the mountain.

ABP1 (Auxin Binding Protein1), who can bind auxin, is essential for the development of plants. It was proved to have the ability to bind auxin and transduce auxin signal into the cells. It is supposed to be localized and functions at the outer surface of plasma membrane through unknown component. In my thesis, we tried to invesitgate the interaction between ABP1 and the candidate of the unknown component, CBP1 (From maize), which is GPI-acnhored and already identified as the binding ability to synthesized C-terminus peptide of ABP1 in 2006. The orthologous of CBP1 in arabidopsis belongs to a gene family with 19 members, in which only three of them were prediceted to be GPI anchored. We did the functional characterisation of these three GPI-anchored members. Data suggested that GPI-anchored SKS were involved in cell orientation, gametophyte and embryo development.

Full textAbstract:
The purpose of this study was to determine whether increased pole stiffness corresponds with higher measures of upper body power in competitive cross-country skiers. Fifteen elite/college level cross-country ski racers (8 men, 7 women) tested UBP on a custom-built double-poling ergometer. Ski poles tested were two models of the same brand with different factory-specified stiffness ratings. Subjects underwent three 10 s UBP tests (W10, W) and one 60 s UBP test (W60, W) for each pole type. UBP measures were defined as the average power output over the length of each test. Video recordings of the 10 s and 60 s tests were analyzed with digital imaging software to determine the maximum bend angle for each pole type. Ergometer and kinematic measures were compared by ski poles tested (stiff vs. less stiff) using a multivariate RMANOVA (α=0.05).

Full textAbstract:
The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers.The experiments showed that during a time period of 30 minutes of rolling on a treadmill (warm-up), μR decreased significantly (p<0.05) to about 60-65 % and 70-75 % of its initial value for freestyle and classical roller skis respectively. Also, there was a significant influence of normal force on μR, while different velocities and inclinations of the treadmill only resulted in small changes in μR.The study of the influence on physiological variables of a ~50 % change in μR showed that during submaximal steady rate exercise, external power, oxygen uptake, heart rate and blood lactate were significantly changed, while there were non-significant or only small changes to cycle rate, cycle length and ratings of perceived exertion. Incremental maximal tests showed that time to exhaustion was significantly changed and this occurred without a change in maximal power, maximal oxygen uptake, maximal heart rate and blood lactate, and that the influence on ratings of perceived exertion was non-significant or small.The study of classical style roller skis μS showed values that were five to eight times more than the values of μS reported from on-snow skiing with grip-waxed cross-country skis.The subsequent physiological and biomechanical experiments with different μS showed a significantly lower skiing economy (~14 % higher v̇O2), higher heart rate, lower propulsive forces coming from the legs and shorter time to exhaustion (~30 %) when using a different type of roller ski with a μS similar to on-snow skiing, while there was no difference between tests when using different pairs of roller skis with a (similar) higher μS.The part of the thesis which focused on skiing economy and efficiency as a function of skill, age and gender, showed that the elite cross-country skiers had better skiing economy and higher gross efficiency (5-18 %) compared with the recreational skiers, and the senior elite had better economy and higher efficiency (4-5 %) than their junior counterparts, while no differences could be found between the genders.Syftet med denna avhandling var att undersöka fristils- och klassiska rullskidors rullmotståndskoefficienter (μR) och klassiska rullskidors statiska friktionskoefficienter (μS) samt effekter av olika μR och μS på längdskidåkares prestation vid rullskidåkning på rullande band. Syftet var även att undersöka s.k. åkekonomi och mekanisk verkningsgrad mellan motionärer och kvinnliga och manliga junior- och seniorlängdskidåkare på elitnivå.Experimenten visade att under en period av 30 minuters kontinuerligt rullande, på rullande band, så sjönk μR signifikant (p<0.05) till 60-65 % och 70-75 % av initiala värden, för fristils- respektive klassiska rullskidor. Undersökandet av olika normalkrafter, hastigheter och lutningars påverkan på μR resulterade i en signifikant, negativ korrelation för μR som funktion av normalkraft, medan olika hastigheter och lutningar endast medförde små förändringar av μR.Studien som undersökte fysiologiska effekter av olika μR visade, vid submaximala konstanta arbetsbelastningar, att yttre effekt, syreupptagning, hjärtfrekvens och blodlaktat förändrades signifikant vid ~50 % förändring av μR. Försökspersonernas frekvens och sträcka per frekvens samt skattning av upplevd ansträngning resulterade dock i mestadels icke signifikanta eller små förändringar. Protokollen med successivt ökande arbetsbelastning (maxtest) resulterade i signifikant förändrad tid till utmattning, vid ~50 % förändring av μR. Detta inträffade utan signifikant skillnad i maximal syreupptagning, hjärtfrekvens och blodlaktat, vilket även mestadels gällde för skattning av upplevd ansträngning.Experimenten som undersökte klassiska rullskidors μS visade att dessa erhöll värden som är fem till åtta gånger högre än vad som rapporterats från studier av μS på snö med fästvallade skidor.Den efterföljande studien som undersökte fysiologiska och biomekaniska influenser av olika μS visade, vid submaximala konstanta arbetsbelastningar, att åkekonomin försämrades (~14 % högre syreförbrukning), hjärtfrekvensen ökade, den framåtdrivande kraften från benen på rullskidorna minskade samt att det blev kortare tid till utmattning (~30 %), vid maxtest, när skidåkarna använde rullskidor med en μS i likhet med vad som rapporterats för skidåkning på snö. För arbetsförsöken med olika rullskidor av olika fabrikat med en högre, och likartad, μS förelåg ingen skillnad i de undersökta variablerna.Studien som undersökte åkekonomi och mekanisk verkningsgrad som funktion av prestationsnivå, ålder och kön, visade att elitskidåkarna hade bättre åkekonomi och verkningsgrad (5-18 %) i jämförelse med motionärerna, att seniorerna hade bättre åkekonomi och verkningsgrad (4-5 %) än juniorerna och att ingen skillnad kunde konstateras mellan könen.

År 2016 vann den norska Tv-serien Skam Foreningen Nordens språkpris på grund av sin förmåga “[...] til å engasjere et ungt nordisk publikum, styrke forståelsen av skandinaviske språkvariasjoner og bygge opp positive holdninger til nabospråkene i Norden”. Men i vilken grad stämmer då detta? Denna uppsats har genom en enkätstudie i tre högstadieklasser i Uppsala undersökt niondeklassares norska ord- och läsförståelse, norska språkbruk och vilka attityder de har till Norge och norskan. Svaren har satts i förhållande till deras uppgivna konsumtion av tv-serien Skam. Resultaten bekräftar Foreningen Nordens påstående om Skams effekter. De som sett Skam har som grupp bättre norsk ord- och läsförståelse, använder till viss del norska ungdomsslang och har mer positiva attityder till Norge och norskan. Undersökningen har även visat att de informanter som inte talar svenska hemma eller som både talar svenska och ett annat språk hemma överlag har sämre norsk läsförståelse än de informanter som bara talar svenska hemma. Denna skillnad i språkförståelsen finns dock inte bland de informanter som sett Skam oavsett deras språkliga bakgrund. Uppsatsen har även ett didaktiskt perspektiv då den undersöker hur Skam kan användas i skolans norskundervisning i svenskämnet.

The goal for this study has been to examine how sexual interactions are portrayed in the norwegian Webb and TV-series Skam. It has been done by studying different elements that are included in a scene with sexual interaction. The scenes has been studied with semiotic content analysis from a multimodal perspective. Other theroies that has been important for this study is the triangular theory of love and a theory about the meaning of music for the in narrative media. The study aims to examine the content, the portrayal and the what message it could give the viewers of Skam. Furthermore the series outplays on several internetbased social platforms, and therefore the viewer comes closer to the characters and gets more absorbed in their lives. The result shows that sexual interactions occurs mostly between persons that is a part of a realationship based on love. Therefore the couple has built a storng emotional bond before they engage in intercourse. Which mostly occurs without verbal communication and therefore there’s music in the scene which can guide the viewer. As the series goes on the characters experienses both positive and negative sides of sexual interactions, as a result the viewer gets a more nuanced perspective about how sexual interactions can play out.

Coupe, Richard. "Towards faster skis : the development of new surface modifications and treatments to reduce overall friction in alpine skiing." Thesis, University of Sheffield, 2013. http://etheses.whiterose.ac.uk/4798/.
Full textAbstract:
Developments in sport technology have been driven by competition and skiing is no exception. Skiing has evolved over many years making use of new materials and post-treatments methods, but in recent years progress has been limited. The low friction exhibited when sliding over snow and ice is governed by the tribological interaction between ski base and snow and the subsequent accumulation of a thin melt water film. The properties of new, innovative, blended ski base materials and post-treatment methods have been investigated using a range of methodologies. The incorporation of fluorinated hydrophobic silica nanoparticles into current ski waxes has been achieved. These nanoparticles have also been used as nano-abrasives to modify the physical surface structure of a ski base composed of ultra-high-molecular-weight polyethylene (UHMW-PE). Such polyethylene samples were also subjected to other physical treatment methods including abrasion with 120 grit, 800 grit sandpapers and 10-15μm silica particles combined with surface planing. The resultant surfaces were examined under a scanning electron microscope, contact angle tested and friction tested. The surface treatments which tended to be both physically and chemically hydrophobic were found to be beneficial at reducing friction in warm and wet snow conditions (snow temperature above -2°C). The addition of carbon black to UHMW-PE was also found to be beneficial in reducing static friction on snow. This was an interesting finding as the unmodified UHMW-PE was shown to be slightly more hydrophobic than UHMW-PE with added carbon from the contact angle evidence. Additionally, the visibly finer surface refinements with micro-scale to nano-scale features were also found to be more beneficial at reducing friction. A hydrophobic fumed silica, polydimethylsiloxane (PDMS), and perfluoropolyether (PFPE) were both blended with UHMW-PE to chemically modify the bulk material in contrast to traditional surface modification with hydrocarbon wax. PFPE, in particular, has been successfully blended with UHMW-PE to produce a novel base material for a downhill ski. Subsequent glide testing of skis, manufactured with this base material, in a range of conditions, demonstrated that the blended white base material closely matched the performance of skis with the current downhill black base material. The new blends also matched a hydrocarbon-waxed surface for hydrophobicity and were also found to be resistance to carbon coating at 5% levels of loading. Combined with the surface planing and nano scale abrasive structuring methods previously described, this novel base material has the potential to either compete or be a compliment to current wax treatment methods in order to achieve the small reductions of friction required to be successful in an alpine race.

This study aims to examine how Swedish fans of the TV-series Skam use the Facebook group Kosegruppa Sverige in order to construct and maintain a fandom, and how fan practices can contribute in creating identity among the members of the group. Theories related to fan research, discourse psychology and intersectionality were applied, as well as a brief overview of earlier research results related to these areas. By using a netnographic approach combined with a discourse analyses, posts made by fans on Kosegruppa Sverige during December 2016 were examined and analyzed. Three main fan practices were found to be used in constructing fandom in the group; fans made their own material such as edits, videos and attire that had a connection to the narrative, they acted out on their fandom both by adapting their language and looks, and finally by buying and selling merchandise and thus collecting things related to the series. Identity was created through intersectional perspectives of gender, sexuality and age. Finally, the study concluded that fandom could be seen as an integral tool within media production, which blurs the line between producers and consumers.

Ce memoire a pour objet de mettre en evidence les facteurs mecaniques influant sur la performance d'un ski de fond et leur correlation avec les resultats d'essais sportifs obtenus sur piste. La multiplicite des parametres a maitriser et leur complexite justifient le fait que cette etude soit principalement experimentale et qu'elle ait conduit a la realisation de plusieurs dispositifs de controle et de mesure. Les skis de fond etant principalement soumis a la flexion, nous cherchons a determiner et a classifier les skis d'apres leur raideur evolutive ei(x). La structure des skis est assimilee a une poutre homogeneisee que nous etudions selon deux methodes reposant sur l'application respective de la theorie des poutres courbes et de l'equation differentielle de la ligne elastique. Cependant, si une allure generale de la raideur evolutive peut etre degagee grace a des methodes classiques d'analyse numerique, l'etude de cette seule caracteristique est insuffisante pour qualifier la performance des skis. Par contre, nous montrons l'importance de la cambrure du ski, d'ou la necessite d'etudier au sol la repartition des charges pour differentes temperatures et qualites de neige. Les courbes obtenues revelent deux maxima dont les positions relatives sont caracteristiques du ski et du positionnement de la charge. Enfin, la correlation permet d'etablir des profils ideaux de repartition selon differents types de neige et, conduit a une meilleure qualification des skis performants. L'etude du positionnement de la fixation nous a amene a l'elaboration d'une fixation amovible permettant de localiser l'emplacement optimal. D'autres etudes d'aspect technico-sportif sont abordees. A savoir, l'etude du comportement du ski aux basses temperatures (modification de la cambrure) et de son amortissement (application d'une technique d'accroissement de ce facteur)

Full textAbstract:
Magíster en Gestión para la GlobalizaciónEl objetivo del presente trabajo es estudiar la factibilidad de incorporar un área para brindar servicios especializados de ingeniería para infraestructura portuaria en la empresa SKM Chile LTDA. La empresa SKM Chile, forma parte de la multinacional Sinclair Knight Merz, la cual posee fuerte presencia en Europa, Asia y Sudamérica. El plan estratégico de la empresa a nivel global, incluye poder ofrecer un servicio integral en cualquier parte del mundo, a sus principales clientes que son las empresas del rubro minero y energético, como BHP Billiton, Rio Tinto y Exxon Mobil, entre otras. Como parte del servicio integral que SKM busca dar a sus clientes, es cada vez más necesario el desarrollo de infraestructura portuaria para graneles sólidos, para el transporte de minerales en el caso de las empresas mineras y de recepción de combustibles fósiles, principalmente carbón, en el caso de las empresas energéticas.SKM Chile, siguiendo los lineamientos de esta estrategia, busca expandir su actividad a la disciplina portuaria y a nuevos mercados geográficos. De acuerdo al análisis de diferentes mercados objetivo, se determinó que las mayores oportunidades para desarrollar el proyecto se encuentran en Chile, Perú y Colombia. Este mercado, en su conjunto, posee un tamaño de aprox. 300.000 HH por un total de aprox. 15.000 millones de pesos. Con la ejecución del proyecto, SKM lograría una participación entre las empresas oferentes que operan en Chile de 6,2% en el 1º año y llegaría a 9,9% a fines del 5º año. Como resultado del análisis de fuerzas de Porter, se determinó que en este mercado, el poder negociador de los clientes es muy alto lo cual disminuye la rentabilidad del proyecto; y el mercado es altamente dependiente de la economía mundial, lo cual puede generar una alta volatilidad a la rentabilidad del proyecto. Debido a ésto, se determinó que el área portuaria, además de estar focalizada en los principales clientes a nivel mundial y ofrecer servicios de ingeniería para puertos exclusivos y de granel; debiese tener como foco secundario otros clientes y entregar servicios de ingeniería también para puertos no exclusivos y multipropósito. Como resultado del análisis FODA, se determinó que la falta de experiencia constituye una debilidad muy importante para realizar el proyecto, razón por la cual, se incorporó un fuerte apoyo por parte de SKM Australia, la cual posee vasta experiencia en el área y asimismo, se le dio una fuerte relevancia a la idoneidad y experiencia de los encargados de comandar los proyectos. Debido a la gran volatilidad, se hizo una evaluación económica basada en 5 escenarios posibles. Para cuatro de ellos se obtuvo un Valor presente neto positivo aunque el cuarto muy cercano a 0, y solo en el escenario más desfavorable se obtuvo un valor presente neto negativo. En el escenario más probable, los ingresos del primer año representan aproximadamente un 1,3% de las ventas totales de la empresa. En dicho escenario, el VPN del proyecto fue de $177 MM, la TIR fue aprox.36%, el Pay back de tres años. Se determinó que con un factor de utilización de 51,7% de la capacidad instalada; lo cual equivale a aprox. 7.500 HH, sería posible obtener un VPN igual a 0. De acuerdo al análisis de sensibilidad, los parámetros más relevantes de la evaluación son el factor de utilización, el cual está directamente relacionado con el volumen de ventas, y también el precio de venta y el tipo de cambio.

Full textAbstract:
Bioethanol is a promising renewable biofuel and wheat is currently the main candidate asthe feedstock for its production in the UK context. The quality of the numerous varieties ofwheat developed in the past by plant breeders has been well examined in terms of bread, biscuitand pasta producing industries. In general, the end-use quality determination of wheat in termsof alcohol yield is less investigated. This work focused on understanding and predicting thealcohol yield from wheat according to its physical, physicochemical and chemicalcharacteristics. The research ran alongside the GREEN Grain project and utilised its wheatsamples, which consist of a range of wheat varieties, agronomic regimes and growing sitesfrom four harvests years 2005-2008. The combined dataset consists of a diverse range ofchemical, physicochemical and physical characteristics of the GREEN Grain wheats. An initial multivariate analysis (PCA) indicated that the first principal component, whichexplains most of the variability of the wheat characteristics, is related with the classification ofwheat as hard or soft. High alcohol yielding wheats typically have high starch, mealiness andalbumin+globulin fraction, and also low protein, gliadin fraction and hardness. They also havelarger and more spherical kernels. Analysis of Variance (ANOVA) was applied in order to identify differences between thevarieties, the sites and the application or not of N fertiliser. The ANOVA showed that theapplication of N fertiliser increases all the protein components, although it increases the Gliadinand the LMW glutenins more. N fertiliser also yields smaller (TGW, width, depth) and moreelongated kernels. High alcohol yielding varieties tend to be softer with lower protein andlarger and more spherical kernels. This consistent variability allowed prediction of the alcoholyield based on easily measured parameters. The following model, based on the SKCS reportedvalues plus protein, could predict the alcohol yield with an R2 of about 78%:Alcohol yield = 466.62 - 5.07 × Protein - 0.21 × hardness + 11.6 × diameter ±6.94 l/dry tonIt is frequently hypothesised that larger and more rounded kernels produce more alcoholbecause they have a smaller relative amount of the unfermentable outer layers. In an effort totest this hypothesis, the pericarp thicknesses and the crease characteristics of the wheat sampleswere measured. It was found that pericarp thickness and crease dimensions vary with kernelsize, with significant differences between varieties. A physical model was developed thatconsiders these differences and calculates the endosperm to non-endosperm ratio. None of thevariables obtained by the physical model could be related to alcohol yield. The SKCS fundamental data were further analysed in an effort to improve the alcoholyield predictability. It was found that the averaged Crush Response Profiles are morereproducible than the hardness index itself. It was shown that the initial peak does not occurbecause of the "shell" (i.e. the bran layers) as suggested in the literature, but because of thecrease. Examination of the effects of moisture content on the aCRPs showed that their 1stquarter is equivalent to the stress-strain plots of dedicated rheological tests. The remaining partsof the curve relate to the post-failure behaviour of the kernels and with hardness as used incereal science. The aCRP parameters could improve the alcohol yield predictability of theGREEN Grain wheats to an R2 of about 82.3% and a standard error of the regression of6.3 l/dry ton. Further standardisation and calibration with respect to the moisture content and tothe size of the kernels could improve the predictions even further. Textural testing of cereals is constrained by the complexity of the wheat kernel structureand exacerbated by the between-kernel variation. The current work has demonstrated howSKCS data can be interpreted more insightfully in order to improve end-use quality predictions. The aCRP parameters clearly contain rheological information about wheats. Further research toestablish their examination by more standardised methodologies will allow effectiveinvestigation of connections between the rheological properties, chemical characteristics,processing behaviour and end-use quality prediction of wheat.

Full textAbstract:
Les canaux sodiques voltage-dépendants (NaChs) ont une répartition hétérogène le long des myofibres qui serait due à deux protéines du cytosquelette sous-sarcolemmal impliquées dans leur ancrage : l'ankyrine, reliée au groupe spectrine et la syntrophine reliée au groupe dystrophine. En effet, la NaChs sont majoritairement concentrés aux jonctions neuromusculaires et leur densité est nettement réduite sur le reste du sarcolemme. Notre travail a consisté en une étude immunocytologique, visualisée par une microscopie optique et électronique, qui nous a tout d'abord permis de préciser la répartition encore mal définie des NaChs le long du sarcolemme extrajonctionnel. Nous avons ainsi pu démontrer que le NaChs sont organisés de façon costamérique sous formez de domaines enrichis en canaux, à l'aplomb des jonctions A/I et des bandes M sarcomériques. Nous avons également utilisé la souris mdx (dystrophine-déficiente) comme modèle, afin d'évaluer les répercussions d'une forte diminution de syntrophine sur la distribution des NaChs. Nos résultats montrent que malgré cette réduction, les NaChs ont une redistribution sarcolemmale normale, suggérant l'existence de systèmes cytosquelettiques d'ancrage redondants permettant d'assurer une fixation efficace des NaChs dans les muscles mdx. Cependant, il s'avère que malgré une répartition des NaChs identique à celle des muscles témoin, les muscles mdx présentent une réduction modérée mais significative de la densité sarcolemmale de NaChs, d'après nos résultats de semi-quantification comparative des protéines grâce à l'analyse d'image sur cryosections immunomarquées. De plus, cette différence de densité de NaChs n'est pas due à une sous-expression des transcrits dans les muscles mdx, puisque nous avons montré grâce à la RT-PCR qu'ils expriment une quantité d'ARNm équivalente aux muscles témoin. Elle pourrait en revanche s'expliquer par une perturbation du système d'ancrage des NaChs sur la sarcolemme, ce qui nous a amenés à étudier plus en détails l'ankyrine, qui n'a jamais été étudiée chez la souris mdx, et la syntrophine. Par la technique d'immunoélectrophorèse, nous avons découvert une nouvelle isoforme d'ankyrine, majoritaire dans le muscle squelettique de souris et dont la quantité est plus importante dans le muscle mdx que dans le muscle témoin. D'après nos immunomarquages, cette isoforme et la syntrophine présentent une distribution très semblable à celle des NaChs sur le sarcolemme des fibres témoin. Par contre, la répartition de l'ankyrine est perturbée dans le muscle mdx, puisqu'elle disparaît du sarcolemme à l'aplomb des bandes M. Ce résultat confirme l'existence d'interactions entre les familles de protéines du cytosquelette sous-sarcolemmal puisque les désordre du groupe dystrophine de la souris mdx induisent les perturbations dans le groupe spectrine.

Full textAbstract:
Cross-country skiing has developed to become one of the most competitive winter sports, where a skier can win by fractions of seconds. Joint efforts between ski technicians and scientist have allowed the development of methodologies to prepare the ski surface, yet much of the knowledge up to date is based on the experience of the technicians. In this sense, much attention is focused on the ski base, given that the friction at the base is an important factor that will define how fast a ski can glide. Ski base preparation is an extensive procedure, due to the several parameters that have to be taken into account. Much disagreement has risen regarding the best way to optimize the base. Thus, a complete characterization of the ski base can help to provide some clarity on the factors that affect friction. This work presents the results of the characterization of the ski base through the preparation process by observing and measuring different aspects, using characterization techniques such as LOM, optical profilometry, contact angle, DSC and XCT. The results suggest that the mechanical machining of the surface can influence wax retention and hydrophobicity. Furthermore, it is seen that wax is present after the first waxing step, despite the constant brushing and scraping. No major changes were observed for the crystallinity. Finally, the amount of graphite on the surface was quantified. This is hoped to be helpful for ski technicians and athletes alike to improve the performance of their skis.

Engenharia Civil – Perfil de ConstruçãoA presente dissertação apresenta uma contribuição para o estudo de escoamentos fluviais, em particular a previsão de alturas de água e distribuição lateral de velocidades em escoamentos em secções compostas. O principal desafio dá-se numa situação de cheia, que ocorre quando o leito principal é insuficiente para o caudal e transborda, passando assim a ocupar os seus leitos de cheia. Nesta situação o escoamento ocorre em secção composta o que leva ao aparecimento de estruturas de escoamento secundário. Para ser capaz de entender melhor o fluxo do rio é necessário continuar a desenvolver modelos analíticos, para que se tornem mais precisos e permitam prever o impacto no escoamento devido a alterações no canal. Nesta dissertação vamos abordar situações de canais de secção composta com rugosidade homogénea e com rugosidade heterogénea. Nesta dissertação adoptou-se o Método de Shiono e Knight (SKM), que é aplicado a canais com rugosidade homogénea e heterogénea. O SKM é conhecido como uma ferramenta capaz de modelar com precisão canais de secção composta. Demonstra-se também que o SKM é capaz de prever, com precisão, distribuições transversais de velocidade média em profundidade. Este modelo contabiliza o atrito do leito, tensões laterais e o escoamento secundário através dos três parâmetros de calibração, nomeadamente ⅄, ƒ, Γ, que por sua vez representam viscosidade turbulenta, resistência do leito e as correntes secundárias respectivamente. Realizou-se um estudo sobre a influência dos parâmetros de calibração do SKM e sobre a divisão lateral do canal que neste caso serve de guia para a calibração e aplicação do modelo. Para a validação do modelo e da calibração efectuada foram utilizados resultados experimentais.

Målet med denna uppsats var att undersöka de nomadiska folkets användning av trä i norra Fennoskandien, samt möjliga analytiska metoder att studera arkeologiskt trämaterial. Detta möjliggjordes genom relevanta etnografiska, historiska och arkeologiska studier och en genomgång av analytiska metoder. De nomadiska folken använde trämaterial i en stor del av deras vardag så som mat i form av den näringsrika inner barken, ved för eldning, till både temporära och permanenta kåtor, förvarning samt jakt. De analytiska metoder som presenteras var träidentifikation, dendrokronologi och 14C-metoden. Träidentifikation möjliggör de två senare metoderna som kan förse tillförlitlig datering beroende på trämaterialets struktur samt tafonomiska processerThe aim of this thesis was to investigate the nomadic people’s wood usage in northern Fennoscandia, as well as possible analytical methods of investigating wooden remains. This was achieved through relevant ethnographic, historical and archaeological studies and a review of analytical methods. Wooden material played a big role in the life of the nomadic people in the shape of food, firewood, storage, construction material for both temporary and permanent huts, and for hunting. The analytical methods presented are species identification, dendrochronology and 14C-method.

Full textAbstract:
Dans l'experience iliha on realise des profils de refraction sismique montrant la stratification de la lithosphere subcrustale sous le sud-ouest de l'iberie. Les profils dans plusieurs azimuts et avec un point milieu commun permettent d'etablir une anisotropie azimutale dans les couches a forte vitesse, de direction n-ne. Une tentative de mise en evidence de la birefringence d'ondes s telesismiques au meme endroit permet de discuter les causes et les modeles de l'anisotropie. Sa direction n'est incompatible ni avec le mouvement absolu de plaques, ni avec la direction d'etirement cadomienne. Sa distribution heterogene en profondeur mise en evidence par la refraction apporte un nouvel element a la discussion de sa location lithospherique ou asthenospherique. La birefringence des ondes sks est alors etudiee en detail au tibet ou les effets sont plus evidents. Un enregistrement en reseau avec une densite exceptionnelle permet de discuter la signification de mesures isolees et les limitations des methodes d'analyse habituelles. On etablit que la direction d'anisotropie change notablement, de 90 et brutalement, en peu de dizaines de kilometres au passage du haut himalaya et de la suture de l'indus-tsangpo. Elle reste stable et est associee avec un retard des ondes, au nord, suggerant un flux impliquant de la fusion partielle

Thesis, Högskolan i Halmstad, Sektionen för ekonomi och teknik (SET), 2011. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-16555.
Full textAbstract:
Rapporten innefattar hur en funktionsprototyp till ett vinterhjälpmedel för en rollatorutvecklats. Alla de väsentliga stegen i utformningen beskrivs grundligt, från det att idéerkläcks tills dess att prototypen är klar för tillverkning. Utifrån en idé om ett vinterhjälpmedelhar arbetet fortlöpt till en prototyp bestående av en konstruktion med skidor som enkeltmonteras på rollatorn. Arbetet berör ergonomiska analyser på användande av prototypen samtdimensionering.Stor vikt under utvecklandet har lagts vid människan och hennes funktion för att få en produktanpassad efter rörelseapparatens förmågor och begränsningar.En nyhetsgranskning över produkten har utförts där utfallet var positivt, vilket innebär attprodukten nu är i ett läge där en patentansökan planeras.Produkten lämnar utrymme för vidareutveckling.The report describes how a functional prototype of a winter aid for a rollator is developed.The essential steps of the design are described in detail, from brainstorming the ideas to theprototype being ready for production. Based on the idea of a winter aid of some sort the workhas proceeded to a prototype consisting of a design with skis that are easily mounted on therollator. The report describes the ergonomic aspects, the analysis conducted on the prototypeand strength of materials.Emphasis during development has been on the man and his function in order to get a productadapted to the musculoskeletal system's limitations and capabilities.A news review of the product has been performed where the outcome was positive, meaningthat the product is now in a situation where a patent application is being planned.The product leaves room for further development.

Full textAbstract:
Vi som författare till denna forskningsöversikt har båda upplevt antisemitiska uttryck under verksamhetsförlag utbildning på våra partnerskolor runt om i Malmö och Skåne. Det finns även utifrån, en snabb Googlesökning tydliga tecken på att antisemitiska uttryck är vanliga i Malmö. Vi har utifrån våra förkunskaper identifierat ett behov av kunskap om begreppet antisemitism samt hur fenomenet uttrycker sig i den svenska skolan. Med detta behov i åtanke har vi sammanställt ett syfte och en frågeställning som lyder: Vad säger forskning om fenomenet antisemitism och dess uttrycksformer i den svenska skolans värld? Vidare har vi genom vår frågeställning behandlat vad forskning säger om begreppet antisemitism utifrån olika definitioner och kommit fram till hur komplext antisemitism är. Resultat visar till exempel att lärare har en bristande kunskap kring begreppet och denna kunskap skulle behöva utvecklas för att kunna bemöta antisemitiska uttryck i skolan. För att finna svar på vår frågeställning har vi gjort en genomlysning av forskning och undersökningar. I vår konklusion och diskussion lyfter vi vilket värde och relevans denna fråga får till lärarprofessionen och visar på hur lärare kan verka för att bemöta antisemitiska uttryck och vad som behövs samt krävs av oss för att kunna göra det.

Chlebek, Jennifer. "Modelling of simple prismatic channels with varying roughness using the SKM and a study of flows in smooth non-prismatic channels with skewed floodplains." Thesis, University of Birmingham, 2009. http://etheses.bham.ac.uk//id/eprint/688/.
Full textAbstract:
Accurate modelling, both numerical and physical, is vital to further our understanding of flow in rivers. This thesis examines both methods of flow applied to two distinct problems; numerical modelling of flow in simple channels with heterogeneous roughness and physical modelling of flow in compound channels with skewed floodplains. In this thesis, the Shiono and Knight Method (SKM) is applied to homogeneously and heterogeneously roughened channels. The SKM is shown to be capable of accurately predicting the lateral distributions of depth-averaged velocity and boundary shear stress for both roughness types. Furthermore, the percentage shear force on the wall of a channel is accurately obtained for both roughness types and guidance is given as to the choice of the three calibration coefficients the model requires, namely f, l and G representing friction, eddy viscosity and secondary flow respectively. Finally, physical modelling has been undertaken on compound channels with skewed floodplains in addition to a full review of the work undertaken at a larger scale in the Flood Channel Facility. As a result appropriate expressions for shear force and apparent shear forces acting on the horizontal and vertical interfaces have been established.
