Abstract:

Le laminage à chaud des aciers représente une des étapes les plus critiques dans l'obtention de produits finis ayant une bonne qualité de surface. L'augmentation de la productivité ajoutée à l'accroissement des besoins du client induit des règles de plus en plus sévères pour les trains à bandes. L'aspect de surface d'une bande est un enjeu très important en termes de coûts d'opération du laminoir et de limitation de productivité. Parmi tous les défauts de surface, le plus défavorable provient de la couche d'oxyde (calamine) formée à la surface de l'acier pendant le laminage à chaud, à l'entrée du finisseur (dernière partie du laminoir): la calamine secondaire dont le comportement mécanique est toujours mal connu. La calamine secondaire peut être fissurée sous les contraintes imposées par les passes successives de laminage, et peut être incrustée dans son substrat en acier; ce défaut est appelé "défaut de calamine incrustée". De plus, l'extrusion du métal sous-jacent dans les fissures de calamine engendre d'importantes modifications locales des conditions de frottement et de transfert thermique. En conséquence, une description précise des mécanismes de déformation de la calamine est nécessaire pour définir au mieux les conditions aux limites sous emprise, et mieux comprendre les mécanismes de défauts d'incrustation. Notre objectif scientifique est donc de réaliser un modèle physique et numérique réaliste, capable de simuler l'écoulement de la calamine dans une emprise de laminage, et en particulier son endommagement. Après la présentation du procédé industriel et du contexte de l'étude, les propriétés physiques et mécaniques des calamines dans le finisseur sont mises en évidences. Le logiciel éléments finis Forge2® sélectionné pour cette étude pour simuler le comportement de la calamine dans une cage de finisseur est présenté. Les développements numériques réalisés pour simuler les différents types d'endommagement de la calamine (fissure, décohésion, glissement, extrusion) sont décrits. Trois tests mécaniques ont été sélectionnés pour reproduire les sollicitations subies par la couche d'oxyde en entrée d'emprise et pouvant conduire à sa fissuration: le test de flexion 4 points, le test de traction et le bipoinçonnement. Une étude numérique est réalisée en parallèle. Avec ces trois essais mécaniques, réalisés à chaud, la description mécanique d'une cage de laminage est suffisamment complète pour simuler le procédé industriel dans de bonnes conditions.

Hot rolling of steels represents one of the most critical steps to achieve finished products with high surface quality. The increasing productivity added to the rising customer requirements result in more and more severe scheduling rules for the HSM. Strip surface aspect is very important in terms of HSM operation costs and productivity limitation. Among all surface defects, the most crippling comes from the oxide scale formed at the surface of the steel during the hot rolling, at the entry of the finishing mill (last part of the hot strip mill): the secondary scale, mechanical behaviour of which is still poorly known. The secondary scale may fracture under the stresses imposed by the successive rolling passes, and can be embedded in the steel strip surface: this defect is called "rolled-in scale defect". In addition, the extrusion of the subjacent metal inside the oxide cracks induces large local modifications of friction and heat transfer conditions. Consequently, a precise description of oxide scale deformation mechanisms is necessary to better define the boundary conditions in a roll bite and to better understand the initiation mechanisms of rolled-in scale defects. Our scientific objective is then to provide a realistic physical and numerical model to simulate the oxide scale flow in the roll bite and in particular, its damage. After the presentation of the industrial process and the context of this study, the physical and mechanical properties of the oxide scale in the finishing mill are investigated. We introduce the Forge2® finite element software, selected for this study to simulate the oxide scale behaviour in a finishing mill stand. The numerical developments performed to simulate the different kinds of oxide damage are described. Three mechanical tests have been selected to approach the solicitations undergone by the oxide scale at the entry of the roll gap, suspected to be critical for damage: the 4-point hot bending test, the hot tension test and the hot plane strain compression test. A numerical study is performed in parallel. Based on constitutive data obtained from these three mechanical tests, the mechanical description of a rolling stand is sufficient for satisfactory simulation of the industrial process

Abstract:

Mestrado em Engenharia de Materiais
O trabalho de projeto foi desenvolvido em parceria com a empresa Plafesa com o intuito de comparar processos não-químicos de remoção da calamina de laminagem da superfície de chapas de aço-carbono. De entre as várias técnicas possíveis, o estudo incidiu em processos de decapagem mecânica (erosiva e abrasiva) e física (ablação a laser), atualmente procurados dado o seu baixo impacto ambiental. Os métodos utilizados foram os seguintes: jateamento erosivo por via seca, jateamento erosivo por via húmida, jateamento com água a alta pressão, escovagem rotativa com escovas ou lamelas de manta abrasiva e remoção por ablação a laser. Para esta investigação foi feita a caracterização da calamina e da superfície das chapas de aço-carbono, recorrendo a técnicas como: microscopia ótica, eletrónica de varrimento com análise química (SEM-EDS), difração de raios-X (DRX) e perfilometria ótica 3D. Todas as técnicas testadas no trabalho mostram ser capazes de remover a calamina, havendo algumas diferenças no grau de remoção, aspeto e rugosidade final da superfície metálica. A técnica de jateamento erosivo por via seca aumenta a rugosidade (Sa = 4,3-4,7 m) relativamente à original (Sa = 2,1-2,4 m) e leva à formação de resíduos de agente erosivo (alumina ou carboneto de silício) que ficam incrustados no aço. As técnicas de jateamento com água a alta pressão e jateamento erosivo por via húmida provocam uma agressão significativa da superfície da chapa (Sa = 16,5-19,7 m). O método de escovagem rotativa é a técnica que proporciona melhor acabamento superficial, com valores mínimos de rugosidade (Sa = 0,6-1,8 m). A ablação laser garante igualmente a remoção de calamina e valores de rugosidade reduzidos (Sa = 2,0 m) mas o controlo dos parâmetros do processo é crítico, para não ocorrerem fenómenos de sobrefusão e evitar a marcação da superfície.
This project was developed in partnership with Plafesa company in order to compare non-chemical processes for descaling of hot rolled steel sheets. Among the various possible techniques, the study focused on mechanical stripping processes (erosive and abrasive) and physical (laser ablation), currently under scrutiny because of their low environmental impact. The methods used were: dry erosive blasting, wet erosive blasting, high pressure water blasting, brushing with rotating brushes or abrasive lamellae blankets and laser ablation removal. For this investigation the oxide scale and the surface of the carbon steel plates were characterized using techniques such as optical microscopy, scanning electron microscopy with chemical analysis (SEM-EDS), X-ray diffraction (XRD) and 3D optical profilometry. All of the techniques tested in this work were able to remove the oxide scales, although with some differences in the degree of removal, appearance and final roughness of the metal surface. The dry erosive blasting technique increases the surface roughness (Sa = 4.3 to 4.7 μm) relatively to the original one (Sa = 2.1-2.4 μm) and leads to the embedding of the erodent (alumina or silicon carbide) into the steel. The high pressure water blasting and erosive wet blasting techniques cause significant damage to the plate surface (Sa = 16.5 to 19.7 μm). The rotating brush method is the technique that provides better surface finishing with minimal roughness values (Sa = 0.6-1.8 μm). Laser ablation also ensures the removal of scale and the achievement of reduced roughness values (Sa = 2.0 μm). The control of the process parameters is critical to prevent over fusion phenomena and additional markings to the surface.

The late John Martin demonstrated the paramount importance of iron for microscopic plant growth in large areas of the world's oceans. Iron, he hypothesized, was the nutrient that limited green life in seawater. Over twenty years later, Martin's iron hypothesis is widely considered to be the major contribution to oceanography in the second half of the 20th century. Originating as an ecosystem experiment to test Martin's iron hypothesis, iron fertilization experiments are now used as powerful tools to study the world's oceans. Some oceanographers are concerned that these experiments are catapulting ocean science into a new era. The vast stretches of ocean play a key role in the global carbon cycle, and thus in regulating Earth's climate. Some scientists, engineers and international policy makers claim that dissolving iron in the ocean will help stop global warming. Adding large amounts of iron to the oceans may drastically increase the amount of carbon dioxide that phytoplankton can capture from the atmosphere, thereby reducing the most common greenhouse gas. But intentional iron fertilization over great expanses of the ocean may have unintended consequences for the world's largest ecosystem. The open ocean is one of the planet's last frontiers and a part of the global commons. As such, using the open ocean as a means to solve the complex problem of global warming raises deep questions about how humans think of and use the Earth. The question remains: Should humans use the ocean as a means to regulate a changing climate?

Abstract:

The aims of this DPhil were the characterisation of major histocompatibility complex class II β loci in the amphibian species Bufo calamita, determination of fitness of four Bufo calamita populations and measurement of genetic diversity at both microsatellite loci and MHC class II β loci. The genetic diversity at microsatellite loci is considered to be neutral to selection and the genetic diversity seen at MHC loci is adaptive. Fitness in the four populations was measured using the known larval fitness traits age at metamorphosis, growth rates and survival. A 114 base pair section of MHC class II loci was characterised in this study. It was shown here that the diversity at neutral microsatellite markers was negatively correlated with adaptive MHC class II variation. No correlation was found between microsatellite HE and the larval fitness traits growth rate, survival and age at metamorphosis. However, MHC class II diversity was found to be associated with survival, and individuals that were heterozygous at both MHC loci had a significantly higher chance of survival than individuals homozygous at one or both of the two loci. A separate part of this DPhil project was the population genetics of six Irish Bufo calamita populations. The genetic structure was investigated using nine polymorphic microsatellite markers. It was found that all populations had similar and moderate levels of genetic diversity, comparable with those on the coast of north-west England. Toad populations were substantially differentiated, implying little migration between sites within historical times. Phylogenetics and estimates of divergence times supported the hypothesis that populations on the north coast of Dingle separated from those around Castlemaine Harbour many thousands of years ago, and are not recent introductions.

Abstract:

This thesis was written to outline the history of five stone houses, which have survived almost a century of mining activity. The houses are located on a barren mesa, called Calamity, in southwestern Colorado. This work was funded by the Bureau of Land Management, Department of the Interior, in order to explore the possibility of designating this site as a National Historic Site. Men and women lived and worked on this and the surrounding mesas for most of the twentieth century. The lives of the families, the men, women, and children who lived and worked on Calamity Mesa, provided the context for the entire period. These people formed nebulous communities on what could only be called a twentieth-century frontier. I used several methods for this study, including oral interviews with surviving miners and their families, company and government officials, mining engineers, and medical personnel involved in studies concerning the effects of radiation exposure. Government publications, local newspapers, and personal papers of several individuals were also researched. Through the use of these methods I further developed the history of the period, by focusing on Calamity Camp and the lives of the men and women who lived and worked there. The miners who came to Calamity Mesa extracted the carnotite ore from sandstone beds. Originally, miners searched for radium, desired for its illusory cure for cancer. Then they sought vanadium, which was used as a strengthening agent for steel during both world wars . Finally, their goal was uranium, a key component for the production of nuclear weapons and energy. The search for these minerals brought, many working class men and women to the Colorado Plateau. They brought their families to Calamity Mesa and lived in whatever shelter they could find. The stone houses, lived in by generation after generation of miners and their families, who came searching for carnotite, provided a permanence to Calamity Mesa throughout this period.

Abstract:

Using spawn collected from the north Merseyside sand dune system, the effects of temperature on growth, development, metabolism and metamorphosis in B. bufo and B. calamita tadpoles were investigated, together with a limited study on the effects of L-thyroxine. The effects of density on growth, developteI1t and metamorphosis were examined. Physiological and behavioural effects of B. bufo tadpoles on B. calamita tadpoles were also studied. B. calamita spawn and tadpoles survive at higher temperatures than B. bufo. Below20°CB. bufo spawn, and below 15°Ctheir t.adpcl.es, develop at a greater rate than B. calamita. B. calamita spawn and tadpoles' growth and development is faster at higher temperatures. B. calamita tadpoles have higher metabolic rates than B. bufo across the temperature range 15-30°C. Faster rates of metabolism and development in B. calamita result in smaller tadpoles and toadlets than B. bufo. B. calamita may compensate for this with increased metamorphic efficiency in terms of energy. It is speculated that differences in tadpole thyroid physiology could account for observed differences. metamorphic efficiency was greatest, and rates of development and growth maximised/at the tadpoles' preferred body temperature. Increased density reduced growth-and developteI1t of tadpoles, but influenced different stages in the two species. metamorphosis in all B. bufo tadpoles was delayed, whereas in B. calamita a proportion of the population metamorphosed apparently unaffected by increased density. The responses of tadpoles to temperature and density were related to the species' preferred spawning environments. In the presence of B. bufo tadpoles, B. calamita growth, development and metabolism was suppressed. The pattern of development and timing of metamorphosis in B. calamita became similar to that of B. bufo. Inhibition was not relieved by L-thyroxine, and did not effect tadpole behaviour. Mass specific food consumption was increased. It is speculated that the inhibitor is a parasite or a substance which affects assimilation.

Abstract:

La perte et la fragmentation des habitats générées par les activités humaines érodent la diversité génétique intra-spécifique, entrainant l’extinction de populations chez de nombreuses espèces. Paradoxalement, des habitats artificiels comme les terrils du nord de la France favorisent l’installation de populations sauvages. Néanmoins leur localisation au sein d’un paysage très anthropisé interroge sur la pérennité des populations qu’ils hébergent. Cette étude visait à étudier la diversité génétique neutre des populations de Bufo calamita et Pelodytes punctatus, deux espèces d’amphibiens établies dans le bassin houiller et dans des habitats littoraux plus sauvages. Des approches de génétique des populations ont permis de décrire les effets de différents processus micro-évolutifs sur les niveaux de diversité génétique, depuis le processus biogéographique de colonisation des terrils jusqu’au régime d’appariement dans une population, en passant par une analyse multi-espèces de la connectivité paysagère. Les populations de B. calamita du bassin houiller présentent de forts niveaux de diversité génétique pouvant résulter d’introductions d’individus de diverses localités. Toutefois, dans le bassin houiller, une forte différenciation génétique s’observe chez les deux espèces. Cela s’explique au moins en partie par la présence de barrières aux flux de gènes entre populations qui, à long terme, pourrait compromettre le maintien des populations. Enfin, le succès reproducteur inégal des mâles de B. calamita, qui pourrait induire des baisses de niveau diversité génétique intra-population, semble associé à une compétition entre mâles et implique plusieurs stratégies d’appariements
Human activities induce habitat loss and fragmentation that have an erosive effect on the level of intraspecific genetic diversity, decreasing the individual fitness and jeopardizing populations’ adaptive capability. Conversely, new human-made areas, such as spoil heaps of northern France, can provide suitable habitats for pioneering species. Spoil heaps being part of a highly human-fragmented landscape, the likelihood of population persistence is questioned given the scarcity of suitable habitats and the occurrence of potential barriers to dispersal. We studied the intraspecific genetic diversity of two anurans, Pelodytes punctatus and Bufo calamita, located in coalfield areas and semi-natural coastal habitats. We focused on the effects of micro-evolutionary processes of genetic drift and gene flow in shaping genetic structure. We studied (i) the biogeographical history of colonization of coalfield areas in B. calamita, (ii) the landscape connectivity using a multispecies approach, and (iii) the evolutionary determinants of variance in breeding success in B. calamita. In coalfield areas, B. calamita populations showed high levels of genetic diversity suggesting several independent colonization events. Nonetheless, marked local genetic discontinuities were observed within coalfield areas for both species, suggesting occurrence of environmental barriers impeding gene flow that may compromise population viability. Within a B. calamita population, we observed a polygynous mating system involving a possible decrease in genetic diversity. Our results suggested that variance in male mating success was linked to male-male competition and may imply distinct mating strategies

Abstract:

Previous research in TMT reveals that mortality salience (MS; or a death reminder) increases pro-social giving tendencies and consumerism, both serving to shield death-related concerns. However, little is known about resoponse to the extinction of humanity, which may to some degree operate as a mortality reminder. Using global warming as an extinction prompt, we will investigate the effects of communal extinction on preferences for environmentally-friendly products that may combat the extinction threat. Preferences for eniromentally friendly aspects of consumer products as influenced by the experimental manipulation is predicted to be moderated by individual differences in locus of control. Internal locus of control was predicted to generate greater value for environmentally-friendly characteristics that have been socially valued to minimize global warming. Because external locus of control involves a perception of diminished personal influence on the external world, global mortality salience was predicted to trigger a decreased concern for ―green‖ product characteristics among individuals subscribing to this viewpoint. However, we found Mortality Salience to be the biggest catalyst for favoring green-oriented consumer items above and beyond the extinction prompt of Global Warming.

Abstract:

Människan har påverkat landskapet i över 1500 år. Mellan 1870 och 2010 har 99,7% av seminaturella höängar förlorats i Sverige. Detta påverkar många arter som idag kategoriseras som hotade. Även faktorer så som förändrad markanvändning och det industriella jordbruket har påverkat arter negativt. Människans markanvändning resulterar i skapandet av nya nischer som gynnar vissa arter och missgynnar andra. Strandpaddan (Epidalea calamita) är en av arterna som missgynnas av nya nischer. År 2000 och 2005 kategoriserades arten som starkt hotad (EN). Naturvårdsverket införde åtgärdsprogram med syfte att vända på den negativa trenden i strandpadde populationerna. Sedan det första åtgärdsprogrammet trädde i kraft år 2000 har en rad åtgärder vidtagits för att bevara arten i de aktuella utbredningsområden som omfattar Blekinge, Blekinge, Skåne och Västra Götaland. Åtgärderna som ansågs ha högst verkan var ny grävning av småvatten eller fördjupning av befintliga småvatten och växthävd genom bete eller röjning. Populationerna i de två undersökta länen, Skåne och Blekinge, visar positiva trender och verkar ha ökat något sedan år 2004. År 2020 har statusen för arten därför ändrats till nära hotad (NT). Dessa förändringar i populationer sker tack vare de nya nischerna som är speciellt anpassade för strandpaddan då den inte kunde själv kunde anpassa sig efter förändringarna av människans markanvändning.

Abstract:

Lo scopo del lavoro di tesi consiste nello studio petrografico, dalla scala dell’affioramento a quella della sezione sottile, di rocce di basamento cristallino soggetto a metamorfismo e deformazione polifasiche. La zona di studio è la Spiaggia di Remaiolo, Elba SE. Questo settore da un punto di vista geologico fa parte del Complesso di M. Calamita, all’interno dell’Unità di Porto Azzurro. Gli affioramenti studiati mostrano diversi eventi metamorfici: il basamento metamorfico Ercinico e le sue coperture mesozoiche subiscono una sovraimpronta metamorfica Alpina di età Oligo-Miocenica correlabile alla strutturazione della catena dell’Appenino Settentrionale. Successivamente le rocce subiscono un’ulteriore sovraimpronta termometamorfica Mio-Pliocenica legata all’intrusione del plutone La Serra-Porto Azzurro. Il lavoro di campagna ha comportato un rilevamento di dettaglio per creare una Carta degli affioramenti (Allegato 1) e prelevare dei campioni rappresentativi delle litologie. Il lavoro di laboratorio si è svolto su 6 sezioni sottili, realizzate con i campioni prelevati in campagna, tramite l’ausilio del microscopio ottico a luce polarizzata.

Abstract:

The chytridiomycete Batrachochytrium dendrobatidis (Bd) is a parasite which has been blamed for amphibian declines across the world. This study was designed to investigate the effects of Bd on natterjack toads (Bufo calamita), following the discovery of Bd populations of this species in the UK. The effect of Bd on natterjack toads was assessed by fieldwork and experiments. Wild adult natterjacks were tagged and repeatedly tested for Bd during 2009-2011. Captive adults and juveniles from infected populations were also tested in response to changes in environmental conditions. Swabs were used to collect Bd DNA from the skin of study animals. Swabbing did not reliably diagnose infection but the quantity of Bd DNA in swabs (Bd score) provided an indication of infection activity. Immersion in water appeared to trigger Bd zoospore emergence from the skin, resulting in an increase in the likelihood of Bd detection and increases in Bd score. Bd dynamics in natterjack populations were also influenced by salinity. Natterjacks in the UK are found mainly in coastal habitat, where ponds are often inundated by high tides. Adults captured in brackish water were less likely to test positive than those caught in fresh water. Bd isolated from coastal natterjacks was killed in vitro by a salinity equivalent to 50% seawater. The isolate grew fastest at low salinities, suggesting that it may have become adapted to brackish conditions. Despite this adaptation, tidal inundation may be sufficient to disinfect ponds and limit Bd transmission. Capture-mark-recapture (CMR) data from adult natterjacks revealed a weak negative correlation between Bd score and survival in the wild. Males had higher Bd scores than females but survival did not differ between sexes and there was no correlation between Bd score and growth. An experiment showed BD could kill natterjacks if infection activity was boosted by wet conditions. However only 6% of wild adults recorded Bd scores in excess of a mortality threshold derived from this experiment. Many adults and juvenile natterjacks can tolerate Bd infection and act as reservoirs of this pathogen. Despite detection of Bd in at least 14 UK natterjack populations by 2011, no mass mortalities of adult natterjacks have been reported and spawning has continued at all sites. Bd does not appear to have a major effect on natterjacks but this situation may not persist and vigilance should be maintained. Bd isolated from natterjack toads in this study belomgs to a global panzootic lineage (GPL) of Bd which Farrer et al (2011) claim has achieved a global distribution as a result of human activities.

Como una alternativa de solución a la creciente demanda de materiales de construcción de bajo costo, generada por el crecimiento demográfico en las principales ciudades del país, se ha investigado previamente en la PUCP un material compuesto de cemento, papel reciclado, quitosano y fibra de sisal. Este material denominado fibrocemento posee propiedades adecuadas para la fabricación de paneles y calaminas de bajo costo, por lo que la producción de éstas permitiría la construcción de viviendas económicas. En esta línea de investigación, se ha previsto el desarrollo de una planta piloto para la fabricación de calaminas, dentro de la cual, una de las etapas finales de producción consiste en el prensado del fibrocemento para maximizar su resistencia. En este sentido, el objetivo de la presente tesis es diseñar una prensa hidráulica de 100 toneladas para la fabricación de calaminas según las normas NTP-ISO 9933, con la intención de evaluar las propiedades de dichas calaminas como paso previo a su producción en serie. La metodología utilizada para el diseño de dicha prensa se puede resumir en las siguientes etapas: i) Estudio del estado de la tecnología y definición de los parámetros requeridos para el diseño; ii) elaboración de una “lista de exigencias” que cuantifica los diversos aspectos que se deben cumplir al realizar el diseño, tales como la función del equipo, los materiales, la geometría, la rigidez, cargas, fuentes de energía, entre otros; iii) cálculo estructural y diseño del equipo; iv) selección de componentes hidráulicos del mismo y, finalmente, v) se han elaborado los planos de fabricación, así como el costeo y planificación de recursos para su fabricación e implementación. Como resultado, se ha diseñado una prensa hidráulica adecuada para la fabricación de calaminas de fibrocemento según las normas NTP-ISO 9933, cuyas especificaciones principales son: 100 toneladas de capacidad; 550 mm de carrera disponible; dimensiones generales de 1500 x 1700 x 2700 mm; mesa de trabajo de 1370 x 670 mm y 0,3 mm de deflexión máxima (con carga nominal); unidad de presión de 200 bar nominal, 240 bar máximo y 50 litros/min de caudal máximo; motor eléctrico de 15 KW (20 HP) y 1710 rpm y, por último, costo total de fabricación de S/. 70 000.00 aproximadamente.

Bibliography: leaves 91-101.
Technological progress, organisational change and intensified global competition have driven a shift from manual work to 'thinking' jobs that emphasise a whole new range of skills. It is no longer enough for students to show that they are capable of passing public examinations, for to thrive in an economy defined by the innovative application of knowledge they must be able to do more than absorb and feedback information. Learners and workers must draw on their entire spectrum of learning experiences and apply what they have learned in new and creative ways (Seltzer and Bentley 1999). To help equip our learners with the attitudes and abilities that will enable them to meet future problems creatively and inventively (Parnes 1970) we need a curriculum that acknowledges the importance of creativity, as well as teachers who are able to recognise and encourage creative behaviour in their classrooms. In the absence of any formal guidance in this regard, this thesis is an attempt to find out if teachers have the broad and accurate understanding of creativity necessary to do this successfully. To achieve this aim an open-ended questionnaire was compiled and distributed to a number of teachers in a range of teaching contexts. Responses were then analysed qualitatively using a method known as the Constant Comparative Method proposed by Glaser and Strauss (1976). An interactive model of creativity (and thus, one which took into consideration the creative product, the creative person, the creative process and the creative environment) was used to structure the questionnaire and to judge the responses. Using the literature as a yardstick it was determined that, at least on an individual basis, these teachers have an extremely narrow understanding of creativity. It was also evident that there were Significant differences in understanding across contexts. This is an issue that needs to be addressed with some urgency if we intend to be at all successful in our attempts to educate for creativity in this country. A shared understanding of this term needs to be ensured - not assumed - something that could be achieved through the provision of a broad and inclusive set of guidelines.

Abstract:

Inledning: Småvatten som dammar har försummats i bevarande-och övervakningsstrategier där fokus har lagts på större sötvattensmiljöer. Kunskap om småvattens roll i bevarandet av biologisk mångfald är bristfällig men studier har visat att dammar kan försörja fler arter, fler unika arter och mer ovanliga arter än sjöar, floder och vattendrag. I Sverige är 100 av 240 rödlistade sötvattensorganismer knutna till småvatten, där de flesta är arter av evertebrater men inkluderar även 38 % arter av den svenska amfibiefaunan. För att säkra den svenska amfibiefaunan måste faktorerna som missgynnar faunan, framförallt de hotade arterna, bli kända. Att bedöma vattenmiljöer lämpade för framgångsrik reproduktion hos amfibier kan vara komplicerad med hjälp av instrumentmätningar och vattenprover då kemiska parametrar i vattnet är ostabila. Alternativt kan man studera sötvattenslevande makroevertebrater där sammansättning, förekomst eller frånvaro kan indikera om miljön är utsatt för stressfaktorer. Utdikningar, övergödning och introduktion av invasiva arter har missgynnat amfibiefaunan genom minska reproduktionslokaler och skapa spridningsbarriärer. I Skånes region, som har högst diversitet av groddjur, har hundratals vatten återskapats för amfibier men behovet att fortsätta med naturvårdsinsatser kvarstår. Syfte: Med denna studie önskar jag lyfta vikten av att bevara och återskapa dammar för amfibier. Studien fokuserar på artrikedom hos amfibier, hotade arter samt reproduktiv framgång hos dessa. Studien omfattar 15 dammar fördelade över tre områden i Skåne. I två områden har flera dammar återskapats för att gynna amfibiefaunan och genom att följa upp kolonisering av dessa och utvärdera reproduktiv framgång, önskar jag bidra med lärdom om naturvårdsinsatsers effektivitet. De två områdena kommer även att jämföras med ett referensområde där inga omfattande naturvårdsinsatser har genomförts. Kemi- och fysikaliska parametrar kommer mätas i dammarna men även makroevertebrater i vattnet kommer att studeras för att se om det finns ett samband mellan dammar med framgångsrik reproduktion hos amfibier och förekomsten av makroevertebrater. Frågorna som ska besvaras är 1) vilket område är mest artrikt? 2) Har naturvårdsinsatserna i relation till referensområdet gynnat hotade arter? 3) Skiljer sig sammansättningen av vattenkemiska parametrar åt mellan dammar med framgångsrik reproduktion hos Anura med dammar utan framgångsrik reproduktion? 4) Skiljer förekomst, diversitet, sammansättning av evertebrater samt andelen rovinsekter åt mellan dammar med framgångsrik reproduktion hos Anura med dammar utan framgångsrik reproduktion? Metod: Projektområdet begränsades till sydöstra Skåne. Två områden, Ravlunda och Högestad valdes ut efter vetskapen om att omfattande naturvårdsinsatser utförts i områdena med syftet att gynna amfibier. Markanvändningen i områdena skiljer sig åt där Ravlunda är ett aktivt skjutfält och i Högestad drivs bland annat jord- och skogsbruk. Det tredje området, Referensområdet, bestod av spridda dammar runt Ravlunda skjutfält. Här hade inga naturvårdsinsatser utförts i syftet att gynna amfibier. Amfibier och deras utvecklingsstadium inventeras under säsongen när gruppen är som mest aktiv i vattenmiljön. Utvalda kemi-och fysikaliska mätningar tas med hjälp av mätinstrument och vattenprover analyseras i laboratorium. Evertebrater samlas in genom håvning för att beräkna Shannons diversitet index och Average score per taxon (ASPT) index. Andelen rovinsekter beräknas från antalet larver av Odonata och individer från familjerna Dytiscidae och Notonectidae. Variansanalyser kommer utföras för att identifiera skillnader mellan områdena och korrelationsanalyser utförs för att identifiera samband mellan evertebrater och framgångsrik reproduktion hos amfibier. Non-metric multidimensional scaling analyser kommer utföras för att identifiera hur lokalerna förhåller sig till varandra i sammansättning av vattenkemi samt sammansättning av familjer och fördelning hos evertebrater. Resultat: Högestad var det mest artrika området. Där var signifikant skillnad i antalet individer av hotad art mellan Ravlunda och de andra områdena. Naturvårdsinsatserna bedömdes gynnat hotad art i Ravlunda men inte i Högestad. Korrelationsanalysen visade inget samband mellan framgångsrik reproduktion och index-beräkningarna. Slutsats: Naturvårdsinsatser i syftet att bevara den svenska amfibiefaunan och dess hotade arter kan vara framgångsrik om man lägger alla bitar i pusslet rätt, för det är många faktorer som spelar in för att insatser ska bli både effektiva och framgångsrika. Att fortsätta med uppföljningar av naturvårdsinsatser efter att projekttiden är slut är viktigt för att kunna ta lärdom om vilka metoder som skapar bäst förutsättningar för stabila populationer hos amfibier.

Abstract:

Calamity of the White Picket is a collection of essays that portray how perfection—whether a perfect image, perfect relationship, perfect friendship, or perfect family—becomes withered down, destroyed, and turned into something else. They explore how the idealized image of a family surrounded by a cute white picket fence is dismantled and rearranged through theft, addiction, and a disintegrated family. The essays explore drug addictions, childhood nostalgia, the relationship between heritage and property, innocence, and a stolen best friend. The collection is a train ride of family problems, broken friendships, lying and stealing, and hidden secrets about love and sex. Through these essays, I let go of my versions of the white picket fence, and embrace the new and complicated life that replaces it, ultimately still trying to maintain happiness.

It is a serious problem in regular calamity strategy of semiconductor industry when diseases were happened in recent years. Not only the data shortage in government’s fire safety law for semiconductor industry but in related research. So, this study focuses on fire hazard response mode in semiconductor factory especially on how the smoke moves produced by a fire. In most cases, the serious losses are always caused by smoke attaching on manufactory facility. Performance based design are taken into consider to retrieving the shortage of restricts in fire protecting law for designing control mode of smoke movement. A CFD software PHOENICS is used to proof the efficiency of calamity strategy. It is the most important controllable variable to adjust the airflow rate of FFU. Using airflow from pressure difference to restrict smoke from spread out is treated to be the basic theory. In this study, increasing the airflow rate in hazard region, the efficiency of smoke exhaust could be better. The increasing of difference in pressure could form a virtual hazard protected region to restrict smoke movement. It would be better to adopt up-exhaust strategy from down-exhaust strategy when fire hazard is happened in FAB zone. Additionally the down-exhaust strategy is a better way in SubFAB fire situation. It is recommended the semiconductor industry should prepare two calamity strategies to face the fire hazard totally.

It is the essential feature of the calamity to be complicated. Adopting the scientific method of complexity is one of the tools of common analysis for calamity system at present. Therefore, regarding complex science as the starting point and focusing on the characteristic discussion, model establishment and application of the spatial-temporal calamity series in this studying six topics are concerned and described as follows: (1) long term memories of simulation and true calamity series are analytic, (2) discussion of time takes place in the calamity by complexity and self-organization critical, (3) exploration of self-organized and complex distribution of earthquake by space complexity, (4) relational analysis and regionalization of anisotropic properties of complex parameters and geologic significance, (5) estimative modeling of shirt series and its application of calamity time series, (6) combination model establishment and its application of space-time series. The study of long term memories of simulation and true calamity series, the Hurst exponent value of simulation and true calamity series are analyzed. The results show that the calamity series hold a strong long-term memory effect. The less obvious of the memory characteristic when the higher threshold value of series or the greater calamity are calculated. Furthermore, according to the case study of both simulated and real earthquakes, more accurate results could be acquired if Hurst exponent can provide relative leading information before the modeling and forecasting. On the discussion of time takes place in the calamity by complexity and self-organization critical, the complexity parematers are calculated and analyzed. It shows that the series of larger scale or grater calamity hold a strong complex feature. The higher threshold value represents the more extreme calamity, and the distribution of series is not uniform in time axis. Before the extraordinary events, it appeared self-organization critical with high variant entropy and complexity. The abrupt variation occurred when small change or sudden event, and a large scale avalanche or a chain reaction will follow. On the exploration of self-organized and complex distribution of earthquake by space complexity, the 2-D complex parameters of earthquake in space are calculated. The lower dimension represents that the tectonic influence in space distribution of earthquake of Taiwan is very great. The result is the same as time series analysis. According to clustering analysis, the self-organization critical represents the feature of different entropy of earthquake, and it will be use to separate earthquake. It shows that the variant complexity represent the change of entropy. The higher entropy and complexity occur in extremely critical events and demonstrate the brittle process of complex system. On the relational analysis of anisotropic properties of complex parameters and geologic significance, the results show that the topographic system does not reveal a high complexity. Different anisotropic characters in complexity parameters are observed along 6 different directions, and it seems that causing by a specific geologic process and/or geomorphologic process. The grouping of chaotic attractor represents the variance required for the interpretation of the elements of topographic system. From the geologic point of view, the linear distribution in structure, lithology and mountain ranges is the direction of NE-SW, and the attractor is 2. The sectors between 70° and 130° have an interpreting variance of 4, the highest value in Taiwan area, reflects the complexity caused by the tectonic movements. On estimative modeling of short series and its application of calamity time series, using gray theory and forecasting simulated calamity series. The R/S forecast method is developed, furthermore, it combining with gray theory to increase the potency of forecasting. The combination of gray theory and R/S method shows an even higher adaptability than R/S and gray method in the forecasting of simulated and natural calamity series. Furthermore, on the two-way decomposition analytical method establishment and application of disaster series, the results show that the effectiveness and suitability are proved by the forecasting of space-time series from the two-way decomposition process, and there is more flexible in choosing model for forecasting. It can be revised two-way when data are the type of multivariable. 　Concluding, the calamity series hold long-term memory and self-organization critically that analyze by complex analyses and contribute the results to data forecasting. According to the forecasting, modeling and natural data, the results show that the effectiveness and suitability are proved from the combination of gray theory and R/S method and the the two-way decomposition process.

A Natureza é mãe e madrasta. A 29 de outubro de 2018 uma violenta tempestade atingiu as montanhas onde se localiza a associação cultural Arte Sella, em Borgo Valsugana, Itália, devastando hectares da floresta secular e destruindo cerca de metade das obras de arte no parque artístico. Num contexto de pós-catástrofe natural, a necessidade de planeamento e novo programa são urgentes e levam a associação cultural a aliar-se numa parceria com o concurso internacional Young Architects Competitions, lançando o Calamity Atelier na procura por ideias para regenerar o maior parque artístico do mundo contemporâneo. A participação no concurso aliou-se à realização da presente dissertação, que pretende dar resposta aos problemas que motivaram o lançamento do Calamity Atelier e visa aprofundar o projeto de arquitetura e problemáticas práticas e concetuais associadas ao ato de projetar, numa tentativa de reconhecer as ferramentas e mecanismos de resposta, conscientes ou subconscientes, adotados ao longo do processo criativo. Assim, o objetivo da dissertação coincide com o propósito do projeto de arquitetura em si - dar resposta a um problema, programa e necessidades específicos - mas visa também no modo de pensar e fazer arquitetura, assente na compreensão física e sensorial de um lugar com elevado valor paisagístico, onde a obra arquitetónica deve surgir como mediador da relação entre o Homem, a Arte e a Natureza.

Abstract This study analyses United Nations’, America’s and Japan’s regime of prevention and rescue from tsunami and their lessons. Next, the problems and their countermeasures of Taiwan’s regime of prevention and rescue from tsunami are also discussed in order to be a reference when improving the regime. The results of this study are summarized as follows: 1. The damages causing by tsunami include destruction of building, people’s death, damage of float, paralysis of traffic and flood. Learning from lessons, it will cause a lot of damages when tsunami occurs. A damage causing from tsunami often makes a great impact internationally and globally. It can not be dealt with by a single country. On the contrary, it needs to be dealt with by joining the international organization and cooperating with each other. 2. Integrated regime of prevention and rescue means that one organization which can integrate all of relevant resources, has a coordination function, uses limited resources and improves the regime. In order to achieve the goals of protection of human life and safety of property, the damage management should adopt prevention, preparation, tackling, restoring stages. 3. Tsunami is not included in to the Taiwan’s Prevention and Rescue Act. Because implement of prevention tsunami work are lack of act authority, it will impact process of the prevention and restoring work. 4. Prevention system is a better system in the tsunami prevention system. However, tsunami is included into the project of prevention and rescue in 2007. Most of county and municipal governments don’t have the projects. The emergent work is to survey the basic information of tsunami damage. 5. From comparing Taiwan’s regime of prevention and rescue with American’s and Japan’s, the results show that our legal system, organization system, policy planning get better. The basic survey of damage, education and training items have to be improved. There are only a few projects in these respects. 6. This study suggest that the policy-making institute which can coordinate cross-sectors in the central government and coordinate the works among the different lever chief governments in order to do the work of tsunami prevention and handling and restoring well.

Taiwan is a typical island country in the west Pacific Ocean, and there is much rain during the typhoon season from June to September. In Taiwan, the mountainside is developed overly and the population is crowded, hence the mudflows and landslides is major thing which people care about every year. On the other hand, the development of the Low Date Rate Wireless Personal Area Network（LR-WPAN）is mature gradually and LR-WPAN has the characteristic of low date rate, low power consumption, short transmission distance and low volume…etc. The application of LR-WPAN includes the detection of weather, hydrology, river, calamity and wildlife…etc. The date which collected by the sensor is very useful for an academic research. And for the calamity detection of the mudflows and landslides, it is according to earthquake sounds and the humidity of the soil, and the calamity is usually occur in rainy weather, so the detection sensors is in very low date rate state in most of the time and need to transmit data frequently just in the rainy weather. Hence, in this paper we propose a new algorithm to control its data rate and to find a balance between performance and power consumption to achieve the goal of extending battery life.

Wireless sensor network is getting popular by information technology and micro-computer development recent . Taiwan is a typical island country in the west Pacific Ocean，and there is much rain during the typhoon season from June to September. In Taiwan，the mountainside is developed overly and the population is crowded，hence the mudflows and landslides is major thing which people care about every year. On the other hand， the development of the Low Date Rate Wireless Personal Area Network（LR-WPAN）is mature gradually and LR-WPAN has the characteristic of low date rate、low power consumption、short transmission distance and low volume…etc. The application of LR-WPAN includes the detection of weather、hydrology、river、calamity and wildlife…etc. The date which collected by the sensor is very useful for an academic research. And for the calamity detection of the mudflows and landslides，it is according to earthquake sounds and the humidity of the soil, and the calamity is usually occur in rainy weather，so the detection sensors is in very low rate state in most of the time and need to transmit data frequently just in the rainy weather. Hence，in this paper We are aimed at enhanced IEEE 802.15.4 Beacon Order Adaptation Algorithm (BOAA) protocol to achieve more power saving ,then compare and analysis the old and the new BOAA protocol.

Presently, earthquakes occurred frequently in Taiwan. We often heard about that earthquakes cause the building''s structural damage. It also caused the loss of people''s life and property. Second calamity (order calamity) is developing with earthquakes. Earthquake calamity in urban is very serious. In order to avoid the second calamity of earthquakes, which threaten more people''s life and property, the emergency action of evacuation should be executed on time. In order to execute the evacuation of staffs and disasters, we need to make an important strategy appropriately and effectively in short time. Then it will reduce the second calamity and strike. To ease off the negative effect caused by second calamity of earthquakes, the public should be educated with a notion of emergency evacuation at peacetime. Based on what we investigated, we''ll construct a fuzzy multi-objective location-allocation model of refuge. The model can be planed to evacuate and assign personnel swimmingly and equitably within space and time are limited. Then we will combine previous research and use Taipei City for the subject of study. In an actual example, we will analyze research and confer with the application in the light of evacuation when the second calamity of earthquake occurred.

To make a comprehensive survey of the community development in Taiwan . Because the community space mold had transformed and the structure of family and the relationship of neighborhood had changed, the reflection of living in city together frequently take shape independent and separative family residence unit. This phenomenon produces many problems of psychology and substance, family and society. Then central section of Taiwan to go through 921 gi-gi earthquake in 1999, become the important point in community rebuilding with the demand for the changes of the family, community and neighborhood. The mechanism of the community rebuilding is to bring up interdependent and cooperative housing community. It’s to establish harmonious relationships with individual and the multitude by way of interdependent function. To unite strength and unfold to community and neighborhood will become a new and ideal live-together mode. To satisfy family’s requirement and to utilize the interdependent behavior for each other, it gets up to well community development and good environment. It is the design direction of the study. The study uses age-old Chung-Hsing New Village of incurring calamity and waiting for renewal urgently as design and study range. The study selects Kung-Min community of public land as the range. The thesis’s stage of study and design is to emphasize for follows five points: 1.the discuss of the design, 2.to study the estimate standards of cohousing community, 3.to proceed plan and design, 4.to estimate the design and to review, and 5.to study the conclusion. The study of the planning way seeks range from community, neighborhood to the group of buildings. In substance the design states to part by layer of community and building: 1.the layer of community: to take the group of buildings for plan as the principal think. To make use of cluster plan and building form below four floor are to mold the community prototype of helping each other by inhabitants. 2.the layer of building: to use thirteen households of not alike structure to be experimented operation. By the concept of the interdependent way and organized households make to proceed the building. The whole conclusions of design were displayed by cohousing mode of low floor. It’s to respond to the argumentation of this study. During the process of exploring and operating, the study is to emphasis on plan of community and buildings. It leads into community function by helping each other. Then, by human relationship itself will establish good relation in whole community and neighborhood.

The intelligent and fully automatic security-and-monitoring system based on visual information analysis has been the core trend in the security-related industry. Due to the high complexity in these techniques such as real time video processing and image contents analysis, a well developed system product is not available till now in this field. However, except the present functions such as artificial voice/vision watching, remote control, video recording in a fix schedule or by action detection, an intelligent monitoring system should require more. This thesis presents a simple and effective method for automatic disaster detection by real time video contents analysis. Via analyzing the specific feature vectors such as spatial-temporal spectra variation, histogram concentration, and so on, a fully automatic surveillance system is build to substantially overcome the drawbacks, especially in the early warning function for natural disaster or loss caused by human behavior, of the existing digital monitoring systems. In the fire detection processes, we use the color characteristics of flame and the variation of smoke to detect the fire. The real time fire sequence is undergone the Discrete Wavelet Transform (DWT) to obtain its spatial-temporal spectrum, and then we build up a detection architecture according to the spectral property of the smoke and flame. In the flood detection processes, we employ two kinds of the feature to recognize the flood. One is ripple and the other is light reflection. We observe the variation characteristic of ripple in spectrum and extract the variation property for recognizing the ripple when the ground is covered by water. Then employ the intensity and saturation variation in space to check the information variation of ground. And build up the detection architecture to identify the flood condition. The experimental results show that the proposed system not only has good performance but also alleviate the system cost than the present and developing systems. Moreover, the novel idea also opens the future trend in the related security and monitoring industry products.

Regarding to the severe damage resulting from Chi-chi 921 Earthquake, it is urgent to construct a comprehensive strategy for evacuation, which is to arrange appropriate shelters and optimum evacuation routes in advance. The specific aims of this study are to explore how to conduct the residents to reach the designed shelters safely and efficiently as well, and to realize the virtual evacuation route through the network analysis of GIS. In this research, the Nan-tou urban planning area is chosen as the study object. The earthquake resistance, which is estimated according to the shock resistant performance of roads, is applied as the safety index, and the travel-time cost, which is calculated in terms of the numbers of evacuative people, is used as the efficiency index. In order to integrate the safety and efficiency, the “Utility Theory” is adopted as the framework to evaluate the utilities and to judge the priority of factors. It transforms the two indices into the utility value and composes the relative importance between them. The final utility amount is the base of optimum route to the shelter assigned. The survey indicated that safety is the top priority when people choose evacuation route, however, victims of the earthquake often choose the shortest but possibly more dangerous route to shelters under limited information. Matching the evacuative people’s personal route from starting point to the designed shelter with the optimum route, the shortest distance route, and the most travel-time-saving route, the degree of similarity were 79.4%, 86.4%, and 83.7% respectively. Based on the demand of Nan-tou urban planning area, this study suggested increasing three shelters which could improve the average distance of evacuation from 535m to 354.7m, and the average travel time from 416.9 sec. to 276.4 sec. It is obvious that the effect of evacuation had been improved substantially after newly building of shelters and new way to assigned shelters.

The objective of this study is to give education of disaster preventions to primary school students with teaching methods and materials of typhoon disaster prevention as the study issue. The teaching materials should be integrated with the Ability Index of the Nine-Year Curriculum, and the curriculum core should be literacy of disaster prevention indicated by the Ministry of Education. The Taipei Citizen Disaster Prevention Guide is used and combined with major disaster cases for supplementary curriculum materials. "Questionnaires of typhoon phenomenon and prevention concept" are the study tool, and the study object is fifth-grade students in two classes assigned as the experiment group and control group and given tests respectively, which is a quasi-experimental method. The experiment group is taught with the Taipei Citizen Disaster Prevention Guide combined with calamity cases as teaching materials of typhoon disaster prevention, while the control group is taught only with the Taipei Citizen Disaster Prevention Guide. The results show that the students in the experiment group perform significantly better than those in the control group in "disaster prevention attitude" (p < 0.05). On the other hand, a high positive correlation between "disaster prevention knowledge" and "disaster prevention skills" is found, while a middle positive correlation between "disaster prevention knowledge" and "disaster prevention attitude" is revealed. In the study, execution suggestions of education of disaster prevention in primary schools in the future based on the study results are also proposed.

Os anfíbios estão a enfrentar actualmente uma vaga de extinções. Grande parte das ameaças que os afectam é geralmente difícil de travar em tempo útil, pelo que a conservação ex-situ, desenvolvida sobretudo em parques zoológicos, pode vir a ser o último recurso para a sobrevivência de muitas espécies. Estas instituições desempenham um papel primordial na manutenção/reprodução das populações, com vista à sua reintrodução, e no aumento do conhecimento sobre as mesmas, tanto ao nível da comunidade científica, através do desenvolvimento de projectos de investigação, como ao nível do público em geral, através dos programas educativos. Apesar do desenvolvimento dos anfíbios estar condicionado por diversos factores, é a nutrição que exige maior atenção para garantir o sucesso dos programas de conservação ex-situ. Contudo, ainda muito pouco se sabe sobre as necessidades nutricionais das diferentes espécies, principalmente na fase larvar. Neste estudo foram testados quatro tipos de alimentação comercial distintas ao nível do teor em proteína (25,9%, 32,0%, 38,3% e 46,2%) em girinos de sapo-corredor, Epidalea calamita. Estudaram-se as taxas de sobrevivência e os parâmetros de crescimento ao longo de 96 dias. Constatou-se que, para esta espécie, os melhores resultados foram atingidos usando a dieta com maior teor proteico, apesar do peso final dos recém-metamorfoseados não apresentar diferenças significativas nos quatro tratamentos. Porém, os esforços de conservação só serão bem sucedidos se as populações estiverem alertadas para esta problemática. Assim, foram realizados inquéritos a grupos escolares visitantes do Jardim Zoológico de Lisboa para averiguar qual a atitude dos alunos face à conservação dos anfíbios. Constatou-se que estes apresentaram uma atitude positiva face à educação e investigação para a conservação de anfíbios, no entanto manifestaram uma resistência à conservação em si se esta se contrapusesse ao bem-estar humano.
The amphibians are facing a serious extinction crisis. The great majority of threats appears to be difficult to stop on time, and therefore an ex situ conservation approach, developed mainly by zoos, may be the last resort for survival of many endangered species. Zoos play a major role in species management and captive breeding programs, aiming at its reintroduction, and in the increase of knowledge about conservation issues, both among the scientific community, through the development of research projects, and among the general public, through educational programmes. Amphibian development is influenced by several factors, among which nutrition requires greater attention to ensure the success of ex situ conservation programmes. However, very little is known about the nutritional needs of these species, particularly in the larval stage. In this study, four commercial diets that differ in protein content (32.0%, 25.9%, 38.3% and 46.2%) were tested on tadpoles of the natterjack toad, Epidalea calamita. Survival rates and growth parameters were studied over 96 days. The results revealed that, for this species, the diet with the highest protein content was the best for its development, despite of the similarity in the final weight of metamorphosed individuals among the four treatments. Conservation efforts will only be successful if humans are aware of this problem. Thus, inquiries to school groups were also carried out at Lisbon Zoo, mainly to investigate which are pupils' attitudes towards the conservation of amphibians. It was noted that the students have a positive attitude toward education and investigation for amphibian conservation, but raise some problems to amphibian conservation if it diminishes human well-being.

Abstract:

Special Topics in Calamity Physics (2006) by Marisha Pessl and Das Blütenstaubzimmer (1997) by Zoё Jenny both feature strong female characters who go through difficult times because they experience genuine disillusionment with regard to their friends, the opposite sex, and, especially, their family. The focus of this thesis was to analyze if the authors depict their characters in such a way that one can see correlations between the emotional behavior of these characters and a phenomenon that is often referred to as adolescent angst. The theoretical foundation for defining adolescent angst and for understanding mechanisms that trigger adolescent angst was provided by Rapoport and Ismond’s internationally appraised DSM-IV Training Guide for Diagnosis of Childhood Disorders (1996) and Reinherz et al.’s ground-breaking study on „Depressive Disorders“ (2006). In my thesis, I was able to show that the depictions of difficult relationships between the protagonists and their parents and friends show characteristics of adolescent angst. Contrary to that, positive influences like reliable friends who are understanding and lend support, function as motivational forces which decrease the protagonists’ anxieties and frustration in both texts. The analysis of the final scenes showed that after all hardships, the protagonists do not give up hope and open themselves up to a once unimaginable future. Although Pessl and Jenny dismiss the concept of a clear didaxis in their texts, they nevertheless imply a motivational message; namely that adolescent angst can be conquered and overcome. I was able to demonstrate that the concept of adolescent angst serves as a catalyst for the development of the protagonists in both Special Topics in Calamity Physics and Das Blütenstaubzimmer . The bestseller status of both novels underlines that the authors’ decision to conclude these novels which are centered around adolescent angst with an open ending seems to cater to a modern young adult readership, especially within the context of pop culture.

With the data collected mainly by participant observation, interview survey and complementarily by field investigation, this thesis tries to have an overall observation and exploration of the collective worships in Pai-bu-fan Settlement. This research is designed for the observation of the collective worships in different community levels, mainly the collective worships in Pai-bu-fan Settlement, from the collective worships with the settlement properties, village properties, to the pan-village properties; and, for the exploration of relationships among the people, ghosts, and gods, represented in the collective worships in Pai-bu-fan Settlement. This thesis consists of six chapters. The topic of chapter one is introduction; chapter two is for the literature review. Chapter three is about the collective worships in the settlement, which present the ways residents seek for blessing and protection from the gods and spirits of nature to satisfy their daily needs, including the ceremony of collective worships to the heaven gods, river gods, earth gods, and the pu-du ritual to pacify the ghosts. Due to the enclosed geographic environment, these ceremony activities form an independent system of collective worships of Pai-bu-fan Settlement. Chapter four is for the pan-village collective worships. This chapter discusses how people from different settlements form social connections through different believes of gods and spirits, and how the interactions among different groups of people are linked by collective worships of gods and spirits of nature. Influenced by the division adjustment of administrative district and the improvement of transportation, the worship activities in Pai-bu-fan Settlement, including the Ping-an opera festival, with village property, in Nei-wan during the Chinese New Year and the the pu-du ritual to the ghosts, with pan-village property, during the Ghost Festival of Er-loon Temple in mid-summer, have been enclosed into the system of Er-loon Temple. Meanwhile, the participation of the Ma-zu procession of Wu-pao Temple has helped Pai-bu-fan Settlement’s collective worships to get out from the fringe of the system of pan-village property. Chapter five mainly focuses on the collective worships of application style. When encountering natural calamities, residents of Pai-bu-fan Settlement, by individual or group worship for blessing, seek for protection from their gods and spirits to get through crises. Among all, they most dread the calamities caused by “good brothers,” the wandering ghosts; therefore, the concept of the pu-du ritual has been intensified. Through activities of the pu-du ritual to pacify the ghosts, residents seek to reach a harmonious status among the people, ghosts, and gods. Chapter six is for the conclusion of this research. This research has found certain features of the collective worships in Pai-bu-fan Settlement. The grass-roots belief of the ceremony of collective worships to the heaven gods in Hakka settlements acts as the recognition of the identification of geographical homeland. The ceremony of collective worships to the river gods originated from the engagement with the floods of Da-an River and has become a distinct feature of collective worships in the area of Pai-bu-fan Settlement. The concept of the pu-du ritual to pacify the ghosts has been intensified by the constantly occurred natural calamities; in this way, the pu-du ritual to pacify the ghosts to “good brothers” is highly emphasized in this area. The external relations which reflect the thought of giving and receiving gained from the collective worships are presented in a variation relation showing cessation, constant involvement, newly involvement of the collective worships in this area. When settlement residents encounter natural calamities, the collective worships for blessing, seek for protection from gods and spirits, are their ways and means of getting through the crises. In an overall view, the collective worships in Pai-bu-fan Settlement represent the ways the residents remain different levels of external relations among settlements and villages, deal with natural calamities, and the embodiment of seeking for blessing and protection from the gods and spirits and their emphasis on the pu-du ritual to pacify the ghosts.
