Displacement Mechanism of Concrete Artificial Reefs

Li, Yi-Lun 07 September 2011 (has links)
The purpose of this study was to integrate the principles of marine geotechnical engineering, underwater acoustic and optical observation techniques into studying the distribution of seafloor sediments and engineering stability of artificial reefs off Yong-an Harbor, Kaohsiung County, south-western coast of Taiwan. The artificial reefs were deployed to the testing site in November 9th, 1996. The goal of this study was intended to describe the engineering status of this reef site and to investigate whether these reefs were moved and buried or not; as well as, to predict whether additional reefs should be deployed to this site in the future. Long-term monitoring of underwater targets was conducted by using of side-scan sonar system, echo sounder, sub-bottom profiler, and underwater video camera. The utility of side-scan sonar system was to depict the topography and terrain features of the seabed. The other equipments were used to complement and cross correlate the results of side-scan sonar observations. In this study, wave forces against reef were estimated by Morison¡¦s equation(ex. Huang, 1995), scouring depth was calculated by Silvester¡¦s experience equation (Silvester, 1974), and the settlement of reefs by theoretical consolidation equation(ex. Das, 1990). The topography of Yung-an reef site is generally gentle and monotonous. The major texture of surficial sediments in this site was sandy silt, and some gravel was distributed at the southern part of the site. In terms of the stability on the artificial reefs project, Typhoon was the main factor which causes the reef to slide or roll. Verified by theoretical analysis and monitoring, the study area of the original stacked reefs has tumbled during the research period, while the remaining non-stacked reef shows insignificant displacement and quantity of the settlement found no cases being buried. To sum up, Yong-an artificial reef district in Kaohsiung county, respectively as A, B, C; the stacked reef under normal condition has found no significant reef being buried and moving traces and artificial reefs can fully elaborate by the gathers of the fish. According to the viewpoint of this project , "Direct contact with the reef and the body of the sea-bed " both the forces of the waves and ocean currents when a typhoon strikes is not easy for the reefs to glide. The "stacked reef" which causes the reef to slide or roll when typhoon occurs was caused by both the forces of the waves and ocean currents. "Direct contact with the reef and the body of the sea-bed " in the case of wave period of 10 sec, analysis shows that the wave height must be greater than 5.8 m in order to make the reef slide. "Stacked reef" in the case of wave period of 10 sec, analysis shows that the wave height must be greater than 4.5 m in order to make the reef roll.

Evaluating the career transition phenomenon

Janse van Rensburg, Adelé 18 March 2015 (has links)
D.Comm. (Leadership Performance and Change) / The purpose of this thesis is to develop a theory, which is based on the career transition phenomenon as experienced by transitioning individuals. Specific focus is given to professionals who transition either to a new profession where a new South African Qualifications Authority (SAQA) qualification is required, or to a wholly unrelated non-professional job where no new qualifications are required. This thesis also provides a theoretical overview of the movement from old career concepts to new career concepts and its related influence on both individuals, as well as the organization, as this is the environment in which career transition take place. An interpretive qualitative approach with a specific grounded theory strategy was employed. Data and information was collected by way of memoirs, interviews and literature. The data came from a total of eight participants who each submitted a personal account of their career transitions as they experienced it in the form of a memoir. Additional data was collected via structured interviews, where participants were requested to provide their inputs and comments. These interviews were also a form of member checking, as the questions were developed based on the initial analysis of their memoirs. Information was also collected from literature, where any and all related career transition concepts were explored, and included in the final analysis. The specific application of grounded theory that was followed to analyse the data was Straussarian. This analysis process entails three steps. Firstly, the researcher applied open coding, followed by axial coding, and, lastly selective coding. Each new participant who was analysed was chosen by following the theoretical sampling technique. The qualitative data analysis software programme called ATLAS was utilized to store all data that was collected, including the developed codes and theoretical memos. Mind maps were developed as the analysis progressed and assisted in the development of the final story on career transitions. Data analysis ended when theoretical saturation was obtained.

Comment traduire les phènomenes culturels? : Analyse des adaptations pragmatiques et sémantiques d'un blog

Wennerholm, Anita January 2015 (has links)
Abstract   This paper is the comment and analysis of the translation of twelve articles in a book with the title Dessine-moi un Parisien by Olivier Magny, originally written as a blog in English on internet, but after huge success also recently published in French. It is a creative, expressive and communicative text, which is fun and often ironic when it tries to describe the nature of a native Parisian. As all texts appear in a cultural context, it is part of the translator’s work to adapt the translated text into the new cultural context in which it will appear. This is especially difficult when a cultural phenomenon (expressed by proper nouns, proverbs, idioms etc.) in the source culture doesn’t even exist in the target culture or, if there is an equivalent translation, is associated with a different connotation.   The aim of this paper is to analyze whether it is possible to translate a text full of local cultural references, by using the many pragmatic and semantic strategies and tools proposed in Konsten att översätta (Ingo: 2007) while trying to keep to the original functions of the text.   Two further strategies, foreignizing and domesticating, have also been of interest as they deal with the basic questions why, when and to what degree one should accomplish all the possible changes in order to adapt the text to the new cultural context.   The analysis shows that all the tools have been of great use and that a good translation is possible. To define a suitable strategy in every single situation, the importance of the pragmatic and the semantic meaning have guided us. It further shows that the situation in which the sentence appears is the most important, even though there is another obvious translation. It has also been possible to endeavor ourselves to obtain some “French color” that is so important for the style in the original blog.   Keywords: cultural adaptations, equivalences, cultural phenomenon, foreignizing, domesticating

Etude de la fonction microvasculaire cutanée dans le syndrome de Raynaud : approches physiopathologique et pharmacologique / Study of skin microvascular function in Raynaud’s phenomenon : a pathophysiological and pharmacological approach

Roustit, Matthieu 30 September 2011 (has links)
La microcirculation cutanée a été proposée comme modèle d’étude de la dysfonction microvasculaire globale dans les maladies cardiovasculaires. Par ailleurs, elle est spécifiquement atteinte dans le syndrome de Raynaud, qui est une ischémie paroxystique des extrémités déclenchée notamment par le froid. L’exploration de la fonction microvasculaire cutanée suscite donc un réel intérêt, mais les méthodes d’étude souffrent d’une hétérogénéité importante, et leur variabilité intra-individuelle est mal connue. La première partie de ce travail fait la synthèse des différentes méthodes d’étude la fonction microvasculaire cutanée, et rapporte les résultats de deux études consacrées à leur reproductibilité. Nous avons dans une seconde partie étudié grâce à ces tests la réactivité microvasculaire cutanée dans le syndrome de Raynaud, et mis en évidence des anomalies chez ces patients, notamment du contrôle neuro-vasculaire. La dernière partie de cette thèse est consacrée à l’étude d’approches pharmacologiques ciblées sur les anomalies de la microcirculation cutanée identifiées chez les patients. Nous avons évalué l’effet du sildenafil, un inhibiteur de la phosphodiesterase-5, sur le flux sanguin digital et montré son effet vasodilatateur lors d’un refroidissement local dans le syndrome de Raynaud. Enfin, nous avons étudiés chez l’animal et chez l’homme l’iontophorèse de vasodilatateurs, une approche innovante d’administration locale de médicaments pour augmenter le flux sanguin cutané. / The cutaneous microcirculation has been proposed as a model to study generalized microvascular function in various diseases. Moreover, it is specifically affected in Raynaud’s phenomenon, characterized by transient ischemia in the digits in response to cold. Despite recent advances in methods exploring the cutaneous microcirculation, they still suffer from a lack of standardization. In the first part of this dissertation, we have reviewed the different techniques used to assess skin microvascular reactivity, and studied the reproducibility of reactivity tests. We then used these tests to assess cutaneous microvascular reactivity in Raynaud’s phenomenon, and showed abnormal neurovascular control of the microvasculature in these patients. The third part of this dissertation is dedicated to pharmacological studies targeting the cutaneous microcirculation in Raynaud’s phenomenon. We tested the effect of sildenafil, a phosphodiesterase-5 inhibitor, on digital skin blood flow while cooling locally, and showed increase in cutaneous vascular conductance in patients with Raynaud’s phenomenon. Finally, we assessed in animals and in humans the effect of locally administered vasodilating drugs on the cutaneous microcirculation, by using iontophoresis. This innovative approach may be an interesting treatment in Raynaud’s phenomenon.

Förutsättningar för empati : Vilken betydelse har tidigare erfarenheter och kön?

Wahlström, Robert January 2008 (has links)
<p>Denna studie tar upp betydelsen av att den empatiserande personen har liknande erfarenheter som målpersonen och även betydelsen av könstillhörighet har för förmågan till empati. Metoden för att undersöka detta bestod av att visa ett filmklipp och efter detta fick deltagarna besvara en fråga utifrån deras upplevelser av filmklippet. Deltagare var psykologistudenter och anställda på en pappersindustri. Studien visade på ett signifikant resultat till att kvinnor utan barn hade högre grad av empati än män utan barn och en tendens till att liknande erfarenheter hos empatisör och målperson ökade empatin för män men inte för kvinnor. Att kvinnor visar mer empati än män finns det tidigare forskning som stödjer. Tendensen att liknande erfarenheter ökar empati hos män står dock i motsats mot tidigare forskning.</p>
