Although fiberglass reinforced polyester manholes and wetwalls have been proven by the American Society for Testing Materials (ASTM) and are currently being used in some parts of the world, there still exists a lack of investigation for testing manhole covers made with different inorganic fillers under static and dynamic behavior. The filler would not only improve the mechanical properties of fiber-reinforced polymer matrix composite not otherwise achieved by the resin ingredients alone but also lower the overall manufacturing costs by decreasing the amount of fiber content without adversely affecting the composite’s mechanical properties. The main objective involved the development of fiberglass laminated manhole covers with different inorganic fillers and to study the static and dynamic behavior of the material by performing experimental and numerical analysis. The materials used for the composite laminated test specimens consisted of E-glass woven roving fabric, epoxy, and filler. Two types of inorganic fillers were used for this study, calcium carbonate and high-density adhesive fillers. The static/dynamic test results showed that the laminates made with fiberglass and filler experienced lower performance in tensile strength but higher improvement in flexural strength. The modal analysis results showed that laminates with less filler experienced higher modes within the specified frequency range. This was expected since the material property of filler increased the stiffness and damping behavior in the composite material.

ABSTRACT In 2015, an Agreement was made in Paris at the 21st conference of the Parties of the UN. The purpose of the Paris Agreement was to collectively target climate change and keep the global warming under 2°C. Since then, the strength of this Agreement has been evaluated in numerous ways, optimists and pessimists present arguments for different theories and opinions. While some argue that the agreement is too weak because of its non-binding features and vagueness, others argue that the very same vagueness has opened up a new door. To contribute with a new perspective, the aim of this study is to describe and analyse different conceptions of nature in the Nationally Determined Contributions submitted to the Paris Agreement by Parties who signed it. Based on previous research about different conceptions of nature, an analytical framework is built and used through a text analysis of some of the Contributions. The findings of this qualitative, descriptive case study are meant to create a deeper understanding of the Contributions made to the Paris Agreement, describing if different conceptions of nature are found and whether this affects the way the Parties aim to tackle the climate crisis.

The thesis is devoted to creation of composites of tribotechnical appointment with the increased operational properties based on mechanically activated polytetrafluoroethylene and fillers of various chemical nature. An approach of preparation of a matrix and fillers of various chemical nature for obtaining PTFE-composites by the reasonable choice of a ratio of ingredients and technology of their modifying is offered. The optimum modes of process of mechanical activation of PTFE-matrix, fibrous and disperse fillers are set. Influence of technological parameters of process of mechanical activation on structure, physical and mechanical and tribotechnical properties of the PTFE-composite is studied. It is shown that under the influence of mechanical activation the ordered spherolitic supramolecular structure of matrix PTFE is formed which is characterized micro- and the nanoscale and leads to an increase in the thermal resistance of a modified polymer on (293–353) K. It is established that mechanical activation does not result in noticeable destruction of polytetrafluoroethylene molecular chain, but there are conformational changes which consist in an increase in concentration of the valent and finite CF2 groups that can lead to enhanced physical, mechanical and service properties of the polymer. It is revealed that the main factors that determine tribotechnical and physical and mechanical properties of PTFE are the time of activation and rotating speed of working organs of a mill. It is mathematically proved the practical experimental mode of mechanical activation at which operational characteristics of matrix PTFE are maximum (n = 9000 min.-1, τ = 5 min.). In comparison with non-activated polymer the level of breaking strength has grown by 2,6 times, relative elongation - by 4,3 times, wear resistances – by 1,86 times. Different technological methods of increasing the adhesive interaction between the ingredients of PTFE-composites are investigated. The prospects of using mechanical activation not only of the matrix but also fillers of various chemical nature for improving of operational characteristics of composites are shown. The determining factor of increase in a complex of operational properties of mechanically activated PTFE-composites is forming spherolitic composite structure under the influence of active particles of disperse layered fillers which playing a role of germs of crystallization and formation on a surface of fibers and coke of the interfacial layer of PTFE which contributes to the emergence of a stable spatial cluster of a filler in volume of a matrix of composition and allows to reach the maximum reinforcing effect, thereby, raising strengthening characteristics of the material and its wear resistance. It is revealed that introduction of a binary filler increases wear resistance of the developed composites by (2,6–4,1) times in comparison with two-component composites. The greatest increase in wear resistance at preservation of high values of physical and mechanical properties of PTFE-composites is watched at synergetic effect of application of mechanical activation of a matrix, fillers, their mixing by two-stage mode and use of a binary filler of various chemical nature. The feature of the developed manufacturing technology of PTFE-composites consists in preliminary separate preparation of a matrix and fillers before their mixing by mechanical activation at various modes of the equipment therefore there is an increase in level of their breaking strength by 1,4 times and wear resistances by (3,7–6,0) times in comparison with industrial analogs that increases durability of work of frictional units of the compressor by (1,8–2,3) times. Piston rings and packing seals of piston-type compressors 4ГМ 2,5 У-3,4/2,8-251 are made of developed PTFE-material that successfully passed industrial tests at LLC «Scientific and innovative enterprise SumyPlastPolymer» and they are not worse than the industry samples. Technological process of PTFE-composite production is developed.

This work aims to describe the integration of multiple factors for the construction of reference. We consider that referentiation is built by the social-cognitive work undertaken by individuals in order to establish objects of discourse. Thus, we argue that such action is carried out through complex strategies, which are not limited to the presence or value of nominal expressions that take part on textual surface. The fundamental theoretical background is the social-cognitive paradigm, from which we propose a new view on analysis taken by Text Linguistics researchers. On one hand, we sustain that other semiosis, besides the verbal one, once they are part of textual materiality, can accomplish the same strategies normally described with an exclusive focus on linguistic constructions. On the other hand, we suggest that observation of texts different from those usually analyzed could provide new proposals about the description of referential processes. We analyze, in this thesis, a complete short tale and four episodes of a TV series, in order to investigate how material elements, linked to context, promote the introduction and reformulation of objects built in texts. For such analysis, we elect three main assumptions: 1) the verbal content which takes part in referential processes is not limited to anaphoric relations between referential expressions; 2) image, when it is part of the text, must be considered as textual materiality to be analyzed; 3) the referent transformation is a process more discursive than formal; thus it is inherently not linear. Through the application of these principles to the analysis of our sample, we define four general steps of referentiation: presentation, addition, correction and confirmation.
Este trabalho tem como objetivo descrever a integraÃÃo de mÃltiplos fatores para a construÃÃo da referÃncia. Partindo da concepÃÃo de que a referenciaÃÃo contempla o trabalho sociocognitivo empreendido pelos sujeitos para a construÃÃo dos objetos de discurso, defendemos que tal aÃÃo Ã realizada por meio de estratÃgias complexas, as quais nÃo se limitam Ã presenÃa ou ao valor dos sintagmas nominais que fazem parte da superfÃcie textual. Como pressuposto teÃrico fundamental, elegemos o Sociocognitivismo, a partir do qual propomos um redimensionamento acerca das anÃlises efetivadas em LinguÃstica Textual. De um lado, sustentamos que os outros modos de enunciaÃÃo, alÃm do verbal, por fazerem parte da materialidade do texto, podem efetivar as mesmas estratÃgias normalmente descritas apenas com foco nas construÃÃes linguÃsticas. De outro, sugerimos que a reflexÃo sobre textos diferentes dos normalmente analisados pode fornecer novas propostas descritivas dos processos referenciais. Optamos por analisar, nesta tese, um conto completo e quatro episÃdios de um seriado de televisÃo, a fim de verificarmos como os elementos da materialidade, conjugados ao aparato contextual, promovem a apresentaÃÃo e a reformulaÃÃo dos objetos textualmente acionados. Partimos das ideias de que 1) o conteÃdo verbal que participa da aÃÃo de referir nÃo se limita Ãs relaÃÃes anafÃricas entre expressÃes referenciais; 2) a materialidade textual analisada deve considerar o modo de enunciaÃÃo visual, quando este fizer parte do texto; e 3) o processo de transformaÃÃo dos referentes Ã mais discursivo que formal, por isso Ã constitutivamente nÃo linear. A partir desses princÃpios aplicados Ã anÃlise de nossa amostra, definimos quatro etapas gerais do processo de um referente: apresentaÃÃo, acrÃscimo, correÃÃo e confirmaÃÃo.

Different styles of natural history film evoke distinct feelings and emotions about wild animals which viewers use as a basis for their perception of wildlife. I define three categories of nature film which reflect varying degrees of human-animal interaction, anthropomorphism and aesthetics: the testimonial, explanatory and non-verbal styles. Although each one is limited in its ability to represent wildlife accurately, it is important to realize that they all show animals from different perspectives (from most to least human-centered, respectively). Given that the majority of people today gain most of their knowledge about wildlife from natural history programs, it is critical for viewers and filmmakers to understand the impact of these films on society--as both emotional and intellectual conduits into the natural world.

Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. Backwash water from swimming pool facilities is often released to the sewer and contain these compounds. The connected wastewater treatment plant receives this water, where some of these compounds escapes the treatment process, into the recipient. It is therefore important to minimize the levels of organohalogen compounds in the influent water to the wastewater treatment plant. In this study, potential treatment techniques for organohalogen compounds at the swimming pool facility have been investigated. The main focus have been on an experimental column test with four filter materials applied (granular activated carbon, natural zeolites, PoloniteR and Zugol). Real backwash water was used. Furthermore, other techniques have been theoretically investigated as well. The activated carbon directly showed the most efficient removal efficiency (above 95 %), but all filter materials had a removal to a certain degree and became more efficient by time. The results further suggest that the more lipophilic organohalogen compounds are bound to particulate matter and highly affected by physical filtration. Another important conclusion is that the specific activated carbon used in the study is not suitable for the purpose, because it released very high levels of phosphorus in the beginning of the column test as well as showing some practical problems. However, other types of activated carbon exists. Next step recommended is to determine the lifetime of the filters.
När människor badar i bassänger hamnar vanligtvis naturligt organiskt material i dem, såsom urin, svett, hår och hudflagor. Desinfektionsmedlet som tillsätts (oftast klor) har som syfte att avlägsna mikroorganismer, men när naturligt organiskt material hamnar i vattnet kommer också oavsiktliga reaktioner ske och halogenerade organiska föreningar bildas. Dessa föreningar kan kvantifieras via AOX måttet (adsorberbar organisk halogen), vilket är den samlade förekomsten av alla bundna organiska halogener i ett prov. AOX består således av flera hundra olika föreningar, varav vissa är mer lipofila och benämns EOX (extraherbar organisk halogen). Många av de föreningar inkluderade i AOX är bioackumulativa, persistenta och giftiga för akvatiska organismer, även i låga koncentrationer. Förutom att vara miljöfarliga för akvatiska ekosystem, kan de också vara skadliga för människans hälsa. Filtret som renar badvattnet i simhallar behöver backspolas regelbundet och backspolvattnet, som innehåller AOX, skickas vanligen till spillvattennätet. Vid avloppsreningsverket är det visat i ett tidigare examensarbete samt i andra rapporter att en del av de inkommande AOX ämnena även följer med det utgående, renade, vattnet ut i recipienten. Det är därmed av vikt att minimera ämnena redan vid källan, det vill säga på badanläggningen. I denna masteruppsats har behandlingstekniker för halogenerade organiska föreningar undersökts. Huvudfokus har varit på experimentella kolonntester för fyra filtermaterial (granulerat aktivt kol, naturliga zeoliter, PoloniteR och Zugol), men även andra tekniker har studerats teoretiskt. I testerna användes äkta backspolvatten från en simhall. Alla material reducerade AOX till viss del och visade på effektivare reducering efter hand. Det var dock tydligt att det aktiva kolet var mest effektivt och hade hög reducering redan i första mätningen, AOX-reduceringen låg på över 95 % (jämfört med det obehandlade backspolvattnet). Vad som dock var problematiskt med det aktiva kolet var att det släppte höga halter fosfor i början av kolonntestet, vilket också bekräftades med ett skaktest. Dessutom uppvisade materialet praktiska problem. Ur ett realistiskt perspektiv med dessa problem i åtanke, blir det inte hållbart i längden att använda detta specifika kol. Det finns dock många olika typer av aktivt kol, vilka förmodligen är mer lämpliga och som inte uppvisar dessa problem, och kan användas för detta ändamål. Vidare antyder det erhållna resultatet att de mer lipofila föreningarna av AOX (EOX) är bundet till partikulärt organiskt material och därmed påverkas väsentligt av mekanisk filtrering. Det är dock viktigt med en aktiv bindning. Projektet har påverkats av covid-19 pandemin med lägre antal folk på badhusen samt mindre tillgång till laboratoriet vid KTH.

The paper describes synthesis method and colloid-chemical properties of novel α-amino acid based polyesters with controllable hydrophilic-lipophillic balance. Glutamic acid and diols of different nature based polyesters were obtained via low-temperature activated polyesterefication. Such polymers are able to form micellar structures in self-stabilized water dispersion. Solubilization of water insoluble dyes Sudan and toluene in polymer water solution was studied. Due to micelle forming ability and prognosticated biodegradability to non-toxic products, obtained polymers are promising materials for formation of novel dispersed drug delivery systems.

The dissertation examines the entrepreneurial process in the soft sciences field. Since the main difference between hard and soft sciences is in the codification of knowledge, the understanding of why and how a soft science finding can be traded might open the doors to new kinds of entrepreneurship. After the global crisis of the last decade, many disequilibrium situations have arisen. In particular, in the Western World, it has involved the personal and societal spheres where iniquity and injustice conditions have spread. An increasing attention to ethical themes, joint with environmental problems, led to a diffusion of social entrepreneurship in all its facets. So, after framing cultural and educational entrepreneurship inside commercial and social entrepreneurial concepts, the dissertation shows the main frameworks developed by academics and scholars on these specific fields. Two cases of academic entrepreneurship in humanities and social sciences are presented to support these theoretical frameworks. By a side they emphasize the differences between academic startups and spin-offs, while on the other hand they provide cues for an examination of the commercialization of products developed starting from low-codified knowledge.

Group work is defined as an instructional strategy to encourage social interaction among pupils. Pupils are more likely to work in groups to perform their daily based learning activities in most of primary classrooms in England. Pupils sit around the table and apparently work in groups. However, putting pupils in groups does not always guarantee that they interact and communicate with one other to fulfil the theoretical expectations advocated in constructivists’ theories of learning. There can be various factors related to pupils and their context which can affect their interactions to make group work successful in any classroom. This study was aimed to explore the nature of pupils’ interaction and their perceptions of working with others during their routinely organised group work in a state primary school in England. The primarily focus of the study was to analyse the nature of pupils’ interactions under various grouping structures organised by the class teacher, to explore pupils’ perceptions about group work while identifying various contextual, social and cultural factors which can influence pupils’ interactions and their perceptions of group work. In this small- scale qualitative study, I used naturalistic participant observation to observe pupils’ interactions during their routinely organised group work in one primary classroom. I also used informal conversational interviews to explore pupils’ perceptions about their experiences of working with others in groups. Both the class and support teachers of the observed class were also involved in the research to gain their perspectives on the organisation of group work. The qualitative data gathered in form of pupils’ conversations, actions, verbal and non-verbal interactions and dialogues was analysed by using first thematic and later on through discourse analytical approaches. The findings of my research are drawn on the ecological model of Bronfenbrenner which revealed that the pupils adopt dynamic, situational, cooperative and non-cooperative interactions towards their peers during their group work. They participated in task-related discussions and remained cooperative by showing positive social attitudes of helping and encouraging others. They showed non- cooperative interactions by being competitive and showed mistrust towards their peers. The pupils also exhibited gender biased attitudes which influenced their decisions of being cooperative or non- cooperative towards a particular peer. The use of ecological model helped me to illicit that pupils were influenced from their immediate and wider contexts while interacting with their peers. In the immediate setting of the classroom, pupils were dependent on the group structure, teaching instructions and learning tasks to work as a group or as an individual. Similarly, pupils were dependent on and were influenced by their wider contexts (i.e. interpretations of the national curriculum guidance, pupils’ socio-cultural backgrounds and community influences) to adopt competitive and gender biased interactions. In the light of these findings, I suggest that the success of social interactions among pupils is dependent on the context which is interwoven by various internal organisational, social, educational as well as cultural layers. These influences coming from the internal and external contextual layers cannot be ignored in any educational research aiming to investigate classroom practices or pupils’ learning experiences inside the state primary schools.

Epilepsy is not just a medical condition but a social label; successful clinical treatment is therefore only one aspect of epilepsy management. However, the particular ways in which features of an individual’s background and clinical condition influence the impact that epilepsy has on them is not yet fully understood. The voice of the individual living with epilepsy is at the core of this study. Drawing upon research on illness narratives, this qualitative study is embedded in the perspective that knowledge construction relies upon the socially crafted tool of language which facilitates a broader range of perspectives and promotes greater subjectivity. I draw upon the illness stories of fourteen adults with epilepsy to explore how the condition impacts directly or indirectly on daily living and life trajectories, and to re-present the diverse nature and meaning of having epilepsy, including its stigma potential. I conducted in-depth interviews with seven male and seven female participants attending epilepsy outpatient clinics. Interview transcripts were subjected to paradigmatic and narrative analysis in order to examine thematic similarities and differences. Participant stories were identified using Mishler’s theoretical model of ‘Core Narrative’. Narrative encounters with participants reflected both their recent and more distant experiences of epilepsy. What emerged from the stories was a discourse of disruption and difference, with epilepsy often imposing barriers to daily living and to maintaining a positive sense of self as participants searched for meaning. While the stories told were uniquely individual, collectively a dominant plot was seen to emerge. For the adults with epilepsy in this study the plot takes the individual from a beginning of ‘discovery and diagnosis’, through the process of ‘searching for a cause’, ‘negotiating risk and uncertainty’, and, ‘striving for control’. As individuals communicate what is significant to them, attention to patient stories provides insight into how experience is constructed and evolves over time. Due consideration of such stories by health professionals can offer direction in which intervention(s) can occur to ensure the interests and needs of the individual with epilepsy are holistically considered and met.

This thesis focuses on virtual restorative environments – specifically, the way that natural environments have been created in a virtual context to elicit beneficial effects on restoration and stress recovery. As the field of restorative environment research is mostly concerned with studying the environment itself, the interaction between participant and environment tends to consist of open exploration, and other ways to interact are often overlooked. The aim of this thesis was therefore to construct a virtual restorative environment with an additional possibility to interact, and to explore how the interaction is connected to a virtual environment’s perceived restorativeness. To gain deeper understanding about how different people perceived the virtual environments, the experiment was conducted using qualitative measures such as questionnaires, open questions and interviews. The results indicate that the perception of a virtual environment’s restorativeness is a very subjective matter, as the individual differences between the participants affected the way that they perceived the environments.

Thesis (MTech (Applied Sciences))--Cape Peninsula University of Technology, 2007
Changes in plant specIes richness and diversity were investigated in Rocherpan Nature Reserve across a fence (or old fence line) separating 34 years of conservation management, conservation management for 11 years south and north, natural veld grazed by cattle and goats, natural veld grazed by sheep, and strip-ploughed veld grazed by sheep. Vegetation surveys were conducted in September 2001. The modified 20 m x 50 m Whittaker plot design with its attractive features of long-thin plots and the original Whittaker plot design were used. Number of species (as richness data) and the numbers of individual recordings per species per land use (as abundance data) were used in calculations in the 20 m x 50 m (1000 m2 ) plots. The species richness index showed significantly smaller numbers of species in the conservation management 11 years south land. The results also showed an increase in species numbers under the grazing land use systems. The data from the comparative study of the five different species diversity indices showed no significant differences. As a result, the Shannon-Wiener index was selected for further assessing the species diversity index and the species diversity significance of different land uses in the West Coast Strandveld. In this particular study, the species that showed an increase in vegetation cover in response to grazing land use regimes were Hemimeris racemosa (annual herb) and Ehrharta brevifolia (annual grass).

In South Africa the highly threatened status of imperiled lowland fynbos protected areas (PAs) have made conservation managers realize that getting local communities and user groups to beneficially use protected areas involving them in protected area management in a manner that links with local socio-economic priorities is an alternative to the apartheid style exclusionary apporach to conservation, and the only way of securing the future conservation of such areas. The largest nature reserve on the Cape Flats called Wolfgat Nature Reserve (WNR) is used as a case study to examine potential for using this approach.

The logistics department at the Powertrain plant of Volvo Trucks seeks to improve the efficiency within their processes. A new concept solution to the supports (pallets) that hold and carry different types of engine parts during the transportation between the sequencing area and the final assembly line called “The new dynamic pallet based on biomimicry” was presented. The concept solves the issues of the constant modifications in the pallets lead by the changes in the design of the engine parts. The main objectives of the project is the creation of a dynamic pallet, dynamic in this case translates into a modular, flexible to different geometries and scalable system, also the design solution should be inspired by nature (biomimicry) to boost a new sustainable design approach related to the values of Volvo brand. This project required iterative research regarding the principles of biomimicry and systems found in nature. Biomimicry literally means ‘the imitation of life’ but, it is better defined as a design approach to innovation which takes inspiration from systems of nature. It is provided by Volvo as the core of the project, if the result is good then there will be a push to develop new projects following this strategy seeking sustainable solutions to solve human problems. In addition, prototyping concepts from a generation of ideas to testing results were conducted to evaluate the concepts generated. The resulting concept proposal is a whole new system but preserves the functional aspects necessary to integrate the new pallet in the current logistics performance.

This study examined the influence of different virtual manipulative types on the nature of students’ techno-mathematical discourse (TMD) when working with a partner. The research used a concurrent mixed-methods design using identical samples to compare and synthesize the results. For this study, six fifth-grade students participated in nine sessions of mathematics instruction using virtual manipulatives. The study compared three virtual manipulative types: combined (multiple representations, open environment), pictorial (single visual representation, open environment), and tutorial (multiple representations, structured environment). Students’ levels of discourse in generalization, justification, and collaboration were measured as well as students’ use of physical and computer gestures while working with each virtual manipulative type. One-way ANOVAs indicated statistically significant differences in quality of student discourse when using the different virtual manipulative types. When working with combined virtual manipulatives, students’ discussions reflected consistently higher levels of discourse than when working with pictorial or tutorial virtual manipulatives. When working with tutorial and pictorial virtual manipulatives, students’ discussions reflected consistently lower levels of discourse. However, pictorial virtual manipulatives were associated with the largest amount of discussion among student pairs and the highest frequency of gesture use. The results of this study suggest that in order to encourage meaningful TMD, teachers should choose technology tools (e.g., virtual manipulatives) that combine multiple representations (i.e., combined virtual manipulative type) and provide the opportunity to engage in cognitively demanding tasks. The results of this study indicate that tutorial virtual manipulatives did not encourage meaningful mathematical discourse with these student pairs. This means that the tutorial virtual manipulative type may be better suited for the practice of mathematics concepts or for individual learning than for partner work. The patterns and trends identified in this study contribute to the existing literature on the complex issues that surround mathematical discourse and the use of technology in the classroom.

Today, old growth forests are continuously decreasing, due to deforestation, threatening species to extinction. Species dependent on dead wood, different stages of decaying wood, large trees, and forest cover continuity have a particularly high risk of extinction, such as saproxylic beetle species. The aim of this study was to explore effects of forest management and some ecological factors on saproxylic beetles in spruce dominated forests, in County of Östergötland in Sweden. Sampling was done by mounting 175 window traps in 35 study sites of different age, around the county. Results showed that nature reserves had the highest number of species, individuals, and threatened species, while production forest, 15-25 years old, had the lowest. Production forests, 65-85 years old, had similarities in species composition with nature reserves, probably due to historical reasons. To some extent, these kinds of forests provide habitat for threatened species at a landscape level and could provide habitat for more threatened species in the future, with the right management. Quantity and quality of dead wood, basal area/ha, and vegetation cover increased species richness and number of individuals. Suggestions to generate a successful long-term conservation is to increase total amount of dead wood, improve diversity of dead wood, leave more large-sized trees during retention and a mixture of tree species in production forests. This will probably aid species dependent on later successional stages, increase vegetation complexity, habitat heterogeneity, and probably increase both number of individuals- and saproxylic beetle species in production forests in the future.

The process of milling drugs to obtain samples with a desirable particle size range has been widely used in the pharmaceutical industry, especially for the production of drugs for inhalation. However by subjecting materials to milling techniques surfaces may become thermodynamically activated which may in turn lead to formation of amorphous material. Polymorphic conversions have also been noted after milling of certain materials. Salt and cocrystal formation is a good way of enhancing the properties of an API but little or no work has been published which investigates the stability of these entities when subjected to milling. Different milling techniques (ball and jet) and temperatures (ambient and cryogenic) were used to investigate the milling behaviour of polymorphs, salts and cocrystals. All materials were analysed by XRPD and DSC to investigate any physical changes, i.e. changes in melting point and by inverse gas chromatography (IGC) to investigate whether any changes in the surface energetics occurred as a result of milling. Another aim of this thesis was to see if it was possible to predict the milling behaviour of polymorphs by calculating the attachment energies of the different crystal facets using Materials Studio 4.0. These results were compared to the IGC data to see if the predicted surface changes had occurred. The data collected in this study showed that different milling techniques can have a different effect on the same material. For example ball milling at ambient temperature and jet micronisation of the SFZ tosylate salt caused a notable increase in the melting point of the material whereas ball milling at cryogenic temperatures did not cause this to happen. The IGC data collected for this form also showed a contrast between cryomilling and the other two techniques. The study also showed that the formation of salts and cocrystals does not necessarily offer any increased stability in terms of physical properties or surface energetics. Changes in melting point were observed for the SFZ tosylate salt and the IMC:Benzamide cocrystal. Changes in the specific surface energies were also observed indicating that the nature of the surfaces was also changing. The materials which appeared to be affected the least were the two stable polymorphs, gamma IMC and SFZ III. The computational approach used has many limitations. The software does not allow for conversion to the amorphous form or polymorphic conversions. Such conversions were seen to occur, particularly for the metastable polymorphs used, meaning that this computational approach may only be suitable for stable polymorphs.

Gegenstand der Untersuchungen war die Reduktion von Stickoxiden (NOx und N2O) an verschiedenartig präparierten Eisenkatalysatoren (Fe-MF, Fe-beta, Fe-SBA-15). Die Katalysatoren wurden nach Synthese, Kalzinierung und Katalyse mittels EPR und UV/VIS-DRS charakterisiert, und darüber hinaus auch in-situ während des Kalzinierens. Isolierte Eisenspezies aggregieren im Verlauf der Kalzinierung bei 873 K. Sowohl höhere Heizraten beim Kalziniervorgang, als auch ein höheres Si/Al-Verhältnis des Trägermaterials verstärken die Neigung zur Aggregatbildung leicht. Die Verwendung des Katalysators für die SCR von NO führt zu weiterem Wachstum und zur Restrukturierung der FexOy-Cluster. Die Eisenkatalysatoren wurden weiterhin mittels in-situ Methoden (EPR, UV/VIS-DRS, FTIR) untersucht während der SCR von NO durch NH3 und Isobutan, der SCR von N2O mit CO, und im Strom der entsprechenden reinen Eduktgase. Die Ergebnisse korrelieren mit dem katalytischen Verhalten der Materialien. Verschiedene Fe3+-Spezies, welche sich durch ein unterschiedliches Redoxverhalten auszeichnen, wurden identifiziert. UV/VIS-Messungen erlauben die Schlußfolgerung, daß isolierte, oktaedrisch koordinierte Fe3+?Spezies leichter zu reduzieren sind als tetradrisch koordinierte. Im Gegensatz zu isoliertem Fe3+ lassen sich FexOx-Cluster leichter oxidieren als reduzieren, und verbleiben daher unter Reaktionsbedingungen trivalent. Durch ihr hohes Oxidationspotential kommt es, vor allem für die Reaktion mit Isobutan, zur unerwünschten Totaloxidation des Reduktanden. Der Anteil isolierter Fe3+ Spezies korreliert mit der Aktivität der Katalysatoren für die SCR von NO und N2O. Weiterhin hängt zumindest für die Reaktion zwischen N2O und CO der Reaktionsmechanismus von der Art der vorliegenden Eisenspezies ab: an isolierten Plätzen erfolgt die Reduktion des N2O an dem an Fe3+ gebundenen CO. An FexOy-Clustern hingegen läuft die Reaktion als Redoxprozeß (Fe3+ / Fe2+) unter Bildung eines radikalischen Intermediates O-. Der Einfluß der Porengeometrie des Trägermaterials auf die katalytische Aktivität wurde an Katalysatoren mit ähnlichem Eisengehalt und ähnlicher Art und Verteilung der Eisenspezies studiert (Fe-MFI, Fe-SBA-15). Die drastisch höhere Aktivität von Fe-MFI belegt, daß die Lokalisierung der aktiven Komponente in einer Pore mit passender Geometrie (Größe und Struktur) essentiell für die katalytischen Eigenschaften ist. Als weitere, die Aktivität stark beeinflussen Größe, wurde für die Reaktion von NO mit Ammoniak und auch mit Isobutan die Azidität identifiziert, die jedoch für die katalytische Zersetzung oder Reduktion mit N2O keine Rolle spielt.
The reduction of nitrogen oxides (NOx and N2O) was investigated over Fe-catalysts (Fe-MFI, Fe-beta and Fe-SBA-15) which were prepared by different methods have been analyzed by EPR and UV/VIS-DRS ex situ after synthesis, calcination and use in catalysis as well as in situ during calcination. It was found that aggregated species are formed at the expense of isolated Fe species upon calcination at 873 K, and that aggregate formation is slightly favored by calcination with higher heating rates as well as by high Si/Al ratio of the support. Use in SCR of NO leads to further growth and restructuring of FexOy clusters. These Fe-catalysts were studied by in situ EPR, in situ UV/VIS-DRS and in situ FT-IR spectroscopy during SCR of NO with NH3 or isobutane and during SCR of N2O with CO as well as during interaction with single feed components. The results were related to the catalytic behaviour. Different types of isolated Fe3+ sites with different reducibility were identified. Based on FT-IR results which revealed that NO reacts preferably with trivalent Fe, it is concluded that Fe3+ ions reduced under reaction conditions to Fe2+ do probably not contribute to catalytic activity. In general, the degree of steady-state Fe site reduction during NH3-SCR is markedly lower than during isobutane-SCR. This might be the reason for the lower activity of Fe-catalysts in the latter reaction. UV/VIS-DRS results suggest that isolated Fe3+ in octahedral coordination is easier reduced than tetrahedral Fe3+. In contrast to isolated Fe3+ species, FexOy clusters are much faster reoxidized than reduced and, thus, remain essentially trivalent under reaction conditions. Due to their higher oxidation potential, they cause undesired total oxidation of the reductant being much more severe in the case of isobutane. A correlation was found between the fraction of isolated Fe+3 sites in the catalysts and their activity for SCR of NO and N2O. The reaction mechanism of SCR of N2O with CO is Fe site dependent. Over isolated Fe sites, the reduction of N2O occurs via coordinated CO species on Fe3+ sites. The reaction over FexOy sites proceeds via a redox Fe3+/Fe2+ process with intermediate formation of O- radicals. The effect of pore geometry of the support on the catalytic activity was studied by comparing catalytic performance of Fe-MFI and Fe-SBA-15 which contain similar iron content and show similar nature and distribution of Fe species as evidenced by UV/VIS-DRS and EPR. Fe-MFI revealed to be much more active than Fe-SBA-15 in all reactions studied. This clearly illustrates that the confinement of the iron species in pores of suitable geometry (structure and size) is essential to originate their remarkable catalytic properties. Acidity is essential for SCR of NO with NH3 or isobutane but it is not mandatory for direct decomposition or SCR of N2O.

L’objectif de cette thèse est d’améliorer la détermination de la masse des rayons cosmiques d’ultra haute énergie faite à l’Observatoire Pierre Auger. Aujourd’hui cette mesure est faite à travers l’utilisation de télescopes à fluorescence qui nécessitent des conditions de luminosité spéciales réduisantle cycle utile à environ 10%. Trois approches différentes sont proposées:La première approche est une nouvelle analyse. Les muons issus des gerbes horizontales sont déviés par le champ magnétique terrestre. Cette déviation modifie l’empreinte au sol des gerbes atmosphériques et est fonction de la longueur de parcours des muons. Un estimateur de Xμmax, leur point de productionmaximum, qui dépend de la masse du primaire peut être construit.La deuxième approche explore la détection du rayonnement radio émis par les gerbes atmosphériques, une technique similaire à la fluorescence mais sans limitation du cycle utile. La détection du rayonnement de Bremsstrahlung moléculaire est revue et explorée de différentes manières.La troisième approche propose un nouveau type de détecteur pour le réseau de surface, ces détecteurs ayant une réponse distincte aux différentes composantes des gerbes atmosphériques : électromagnétique et muonique. La mesure de la composante muonique est aussi un moyen d’accéder à la nature du primaire.La nouvelle analyse semble un outil prometteur qui peut s’appliquer à tout lot de données. La radio-détection en revanche n’apparaît pas comme une alternative compétitive face aux techniques traditionnelles. Le nouveau détecteur offre de belles perspectives et devrait être considéré pour l'équipementdes futurs observatoires
The motivation of this PhD thesis is to improve the capabilities to determine the mass composition of the ultra-high energy cosmic rays in the Pierre Auger Observatory. The measure of their mass composition is done with the fluorescence technique, that needs special luminosity conditions that reduce the exposure time to about 10% of the time. Three different approaches are proposed.The first approach is a new analysis. Muons in the horizontal showers are deviated by the magnetic field of the Earth. This deflection is related with different characteristics of the extensive air shower that allow the construction of an estimator to obtain an alternative measure of Xμmax, an observable sensitive to the mass of the primary.The second approach is to explore the detection of the radio emission produced in the extensive air showers, a technique similar to the fluorescente one, but without the limitations in the duty cycle. The detection of the Molecular Bremsstrahlung Radiation emission is revised and investigated from different points of view.The third approach is to propose a new surface detector that obtains different responses to the different components of the extensive air shower: electromagnetic and muonic. The access to the muonic component is another way to access to the composition of the primary particle.The new method of analysis proposed appears as a promising tool to be applied in any data set. The technique of the radio detection did not show clear indications of being an alternative to traditional techniques. The new detector represents a promising alternative to be considered in any future ultra-high energy cosmic rays experiment

Aktiviteten där jag även ställt frågor till barnen angående bl.a. vattenloppans utseende och livsmiljö. Samtidigt som jag filmat har jag kunnat observera två grupper som möter dessa djur antingen med hjälp av bild och video eller med verkliga djur. Genom att barnen fick dokumentera sitt möte med att måla vad de varit med om har jag kunnat få en bild om hur barnen uppfattat djuren. Resultatet visa att flera barn i gruppen som fick uppleva de riktiga djuren kunde detaljera sina upplevelser via deras teckningar. Bildgruppen visade dessutom sämre perceptionsförmåga då de hade en vag bild om vattenloppans storlek och att flera barn såg vattenloppans antenner som vassa och farliga tänder.

The activity where I asked the children about such as the water fleas appearance and habitat while I was filming, I have been able to do an observation in two groups that could watch these animals either by image and video or as living animals. The children got afterwards documenting his meeting with painting, I was able to get a picture of how the children understood the animals. The results show that several children in the group who got to experience the real animals could detail their experiences through their artwork. The Picture group also showed poorer perception since they had a vague idea about the water flues size and that several children misunderstood the water flues antennas for sharp and dangerous teeth.

Les matériaux à base de polydopamine (PDA) s’inspirent de la forte adhésion du byssus de la moule sous l’eau. L’oligomérisation de la dopamine dans un milieu basique permet la formation de revêtement de PDA sur n’importe quel matériau. En plus de la simplicité du procédé celui-ci est vert et versatile. La PDA a des propriétés similaires aux mélanines, d’où son utilisation dans le domaine des phénomènes de conversion d’énergie, de l’environnement et du biomédical. Cependant la structure de la PDA étant inconnue, l’élaboration de matériaux basés sur la relation structure propriétés est difficile. L’un des buts de cette thèse a été de comprendre cette relation pour élaborer de nouveaux matériaux de PDA. En choisissant l’oxydant adéquat nous avons déposé un film épais, superhydrophile et biocompatible sur n’importe quels substrats. De plus nous avons découverts la possibilité de former des films de PDA à l’interface air/eau. L’étude de ce phénomène a permis de former des membranes autosupportées et stimuli responsives
Polydopamine (PDA) materials are inspired from mussels’ byssus strong adhesion underwater. The oligomerization of dopamine in a basic medium allows forming a PDA coating on virtually any materials. In addition to the simplicity, ecofriendly and versatility of the deposition method, PDA has properties similar to those of melanin pigments and displays many outstanding properties. Thus PDAis widely used in energy, environmental and biomedical sciences. However design of PDA based new materials with tailored properties is a challenge since its structure is still unknown. In that sense one of the aims of this thesis is to gain knowledge in PDA structure-property relationship in order to design PDA materials with new properties. By choosing the appropriate oxidant we deposited thick and superhydrophylic films on any materials for the elaboration of low fouling and biocompatible surfaces. Additionally we discovered the possibility to form PDA films at the air/water interface. The investigation of this phenomenon led to the formation of stimuli responsive free standing membranes

Metamaterials are humanly engineered artificial electromagnetic materials which produce electromagnetic properties that are unusual, yet can be observed readily in nature. These unconventional properties are not a result of the material composition but rather of the structure formed. The objective of this thesis is to investigate and design smaller and wideband metamaterial-inspired antennas for personal communication applications, especially for WiMAX, lower band and higher band WLAN applications. These antennas have been simulated using HFSS Structure Simulator and CST Microwave Studio software. The first design to be analysed is a low-profile metamaterial-inspired CPW-Fed monopole antenna for WLAN applications. The antenna is based on a simple strip loaded with a rectangular patch incorporating a zigzag E-shape metamaterial-inspired unit cell to enable miniaturization effect. Secondly, a physically compact, CSRR loaded monopole antenna with DGS has been proposed for WiMAX/WLAN operations. The introduction of CSRR induces frequency at lower WLAN 2.45 GHz band while the DGS has provided bandwidth enhancement in WiMAX and upper WLAN frequency bands, keeping the radiation pattern stable. The next class of antenna is a compact cloud-shaped monopole antenna consisting of a staircase-shaped DGS has been proposed for UWB operation ranges from 3.1 GHz to 10.6 GHz. The novel shaped antenna along with carefully designed DGS has resulted in a positive gain throughout the operational bandwidth. Finally, a quad-band, CPW-Fed metamaterial-inspired antenna with CRLH-TL and EBG is designed for multi-band: Satellite, LTE, WiMAX and WLAN.

Este trabalho propõe analisar o fenômeno da terceirização desenvolvido ao longo das duas últimas décadas em Bio-Manguinhos. Trata-se de um estudo de caso realizado na unidade de produção de vacinas e reagentes para diagnóstico da Fundação Oswaldo Cruz. Inicialmente foi realizado um estudo de cenário, analisando a política de gestão do trabalho desenvolvida pelo Estado brasileiro para as instituições públicas. A seguir, a análise passou a verificar a inserção da Fiocruz nessas políticas, desde a sua criação e no decorrer de vigência de diferentes formas de contratação, alternando da extrema rigidez para a total flexibilidade sempre com foco na gestão do trabalho, e, como essas políticas se refletiram no desempenho de Bio-Manguinhos. Baseado no contexto da conformação do Estado e na análise do desempenho da unidade, o trabalho critica a falta de planejamento e de prospecção dessas políticas, que favoreça a inovação de processos, produtos e procedimentos e o desempenho pleno de uma unidade de produção de insumos para a saúde, tão necessários ao atendimento das necessidades da população brasileira. Critica também, a ausência de um modelo de Estado consolidado que sirva de arcabouço à formulação dessas políticas. Devido às fortes críticas dos órgãos de controle acerca da extrapolação dos limites da terceirização praticada nas últimas duas décadas e à falta de definição clara desses marcos legais, o trabalho apresenta uma metodologia baseada nas atribuições dos cargos do plano de carreiras da Fiocruz e culmina com a apresentação de uma matriz de atribuições passíveis de serem realizadas por contratação indireta. Conclui pela necessidade de convivência de dois quadros de trabalhadores: um permanente formado por servidores, estáveis e de carreira e outro flexível, executado por contratação indireta, de caráter eventual, temporário ou de apoio às atividades relacionadas à missão de Bio-Manguinhos. O trabalho ainda sugere a aplicação da mesma metodologia às demais unidades da Fiocruz e que a instituição afirme, frente aos órgãos de controle, quais atividades que ela precisa manter no quadro de servidores permanente e quais ela quer delegar a terceiros sem contudo, ferir a legislação vigente. Por fim, constata-se que a metodologia apresentada ameniza, mas não resolve o problema, dessa forma, recomenda-se à Fiocruz buscar mecanismos que altere o modelo de gestão pelo qual está submetida a fim de viabilizar as duas formas de incorporação de mão-de-obra.

The glass powder and cement were used to replace mineral filler in the SMA in this study. The effects were examined and discussed. The results of the study show that the stability and the indirect tensile strength increased after replacing mineral filler with glass powder. However, it results in the lower resistance to abrasion of Cantabro and moisture damage. It is shown that all the requirements are met after the glass powder was cut down to half . All the requirements are met when the mineral filler is replace by cement.

Nickel-base Alloy 690, due to its superior corrosion resistance at high temperature, was used as the important component material in nuclear power plant. This study is mainly to investigate the influence of nickel-based welding electrodes with different titanium (Ti) addition on microstructure, mechanical properties, and corrosion resistance in the dissimilar weldment of Alloy 690 and SUS 304L. The welding electrodes were changed Ti contents variously by adding Illmenite and pure Ti powder in the flux. Shield Metal Arc Welding (SMAW) was conducted with proper welding parameters according to the American Welding Society(AWS) specifications. Specimens with a V groove were butt welded with three passes in three layers. Finally, the weldments were performed with microstructure observation and composition analysis. Combining with mechanical property tests and Modified Huey Test. The results showed that the Ti addition in welding electrodes degraded the welding operation feasibility, but structure was fined and dendrite arm space was shortened at the same time. The precipitates in weldment mainly gathered on the grain boundary and in the dendrite space. The composition of precipitates transformed from Nb-riched to Nb, Al, and Ti with increasing Ti. In the prospect of mechanical properties, the tensile strength didn’t change significantly and elongation increased obviously to 36.4%, which was superior to Nb addition(291.%) and commercial Inco152 (31.3%) with Ti addition. Meanwhile, the average micro-hardness of weldment raised with Ti addition. For the corrosion test, Ti addition had the tendency of decreasing the Intergranular Stress Corrosion Crack (IGSCC).

Dissertação de Mestrado em Relações Internacionais - Estudos da Paz, Segurança e Desenvolvimento apresentada à Faculdade de Economia
Esta dissertação de Mestrado discute a atual crise ambiental global, com o objetivo de refletir criticamente sobre um dos desafios mais centrais que coloca à sociedade internacional, em geral, e à disciplina de Relações Internacionais em particular: como a resposta a esta crise pode implicar uma transformação radical da relação entre a humanidade e a natureza não-humana, e como isso pode potencialmente remodelar e transformar as comunidades políticas modernas. Começamos por examinar o presente contexto das alterações climáticas através das correntes teóricas do eco-Marxismo, do ecofeminismo e da teoria crítica das RI. Voltamo-nos em seguida especificamente para os trabalhos de Andrew Linklater (1998), Robyn Eckersley (2004) e, em menor medida, Andrew Dobson (2010), explorando a crítica de Linklater ao caráter exclusivo do sistema de estados Vestefaliano e o seu apelo ao alargamento das fronteiras morais da comunidade política de forma a incluir “outros” sistematicamente excluídos; a resposta de Eckersley ao trabalho de Linklater, através de uma proposta não-antropocêntrica para o estabelecimento de alguma forma de Estado pós-Vestefaliano, deliberativo e verde, que inclua os seres não-humanos; e o apelo de Dobson a uma reconceptualização da prática política que reconheça a subjetividade, agência e voz da natureza não-humana. Recorrendo à análise crítica de discurso, olhamos para o estudo de caso do movimento global pelos Direitos da Natureza através de três exemplos a um nível local, nacional e global (o caso do Rio Whanganui em Aotearoa Nova Zelândia; a Constituição de 2008 do Equador; e a proposta de Declaração Universal dos Direitos da Mãe Terra). Exploramos estes exemplos de forma a podermos responder à nossa pergunta de investigação: em que medida é que o movimento pelos Direitos da Natureza representa a emergência de uma narrativa pós-Vestefaliana como um modo de relação alternativo, mais inclusivo e sustentável, com a natureza não-humana, no contexto da crise ambiental global?
This Master’s dissertation discusses the ongoing global environmental crisis, aiming to reflect critically on one of the most central challenges it poses to international society, in general, and to the discipline of International Relations in particular: how the answer to this crisis might entail a radical transformation of humanity’s relationship with non-human nature, and how this might potentially reshape and transform modern political communities. We start by examining the current context of climate change through the theoretical currents of eco-Marxism, ecofeminism and IR critical theory. We then turn specifically to the works of Andrew Linklater (1998), Robyn Eckersley (2004) and, to a lesser extent, Andrew Dobson (2010), exploring Linklater’s critique of the exclusionary nature of the Westphalian states-system and his call for the enlargement of the moral boundaries of political community in order to include systematically excluded “others”; Eckersley’s answer to Linklater’s work, through a non-anthropocentric proposal for the establishment of some form of post-Westphalian deliberative green state that includes non-human beings; and Dobson’s calls for a reconceptualisation of political practice that recognizes non-human nature’s subjecthood, agency and voice. By resorting to critical discourse analysis, we look at the case study of the global Rights of Nature movement in three specific examples on a local, a national and a global level (the Whanganui River case in Aotearoa New Zealand; Ecuador’s 2008 Constitution; and the draft for the Universal Declaration of Rights of Mother Earth). We explore these examples in order to answer our research question: to what extent does the Rights of Nature movement represent the emergence of a post-Westphalian narrative as an alternative, and more inclusive and sustainable, mode of relationship with non-human nature in the context of the global environmental crisis?

Among many financial instruments, stocks are one of the most commonly used investment tools for many investors. Therefore, how to choose investment targets and construct investment portfolios has always been a hot research topic. Many domestic and foreign research literatures have found that Earning to Price Ratio is one of the commonly used and important reference indicators for investing in the stock market. It’s a worthy index for investors to choose stocks. This study mainly adopts the Value Investing to analyze the earning of Common Stock of Taiwan Listed Companies between 2000-2018. It’s sets the “Earning to Price Ratio” as the single investment indictor to compare the performance of portfolio with different nature of earnings for stock selection measurement. Respecting the opinion of Robert J. Shiller, Nobel laureate in economics, the test includes earning for a certain period. The plan is to use the Earning to Price Ratio of 3 different periods (annual, three-years average and the five-years average) to compare the investment performance. Under the different nature of earnings of Earning to Price Ratio, the empirical results confirm that the investment performance of Five-Years Average portfolio is better than others, especially in the “Earning to Price Ratio of Earnings Before Interest” and “Earning to Price Ratio of Net Income-E”. The empirical results of this study provide investors with practical application in the construction of investment portfolios and investment decisions, and improve the performance of stock selection investment.

Ill health, accident and death are themes common to all of Jane Austen's novels. Some illnesses are physical, whereas some of her heroines experience excessive psychological, emotional and spiritual traumas. These references are too numerous to be either coincidental, glossed over or ignored. Austen expressed an interest in the mind/body relationship, believing that illness could be brought upon in certain personalities by the sufferer herself, and it seems that she might have held theories similar to those advocated by Mary Wollstonecraft in A Vindication of the Rights of Woman and even have anticipated those on feminine hysteria, and the effects of unconscious motives on behaviour, which were advanced by Freud in works such as The Interpretation of Dreams. This study examines Austen's novels, and the origin and purpose of physical and psychological illness in these, and looks at how Austen uses illness, accident and death, and more particularly how their roles progressively change and develop. For Austen's handling of these common issues appears to vary and to develop in line with the order of composition of her novels. She places increasing emphasis on them, not just to further plot, but also to reflect character change and development. Many of the parents or guardians of Austen's heroines are inadequate. And so Austen's heroines are often deprived of commendable models, left to find their own way, alone and in need of emotional support, to confront their youthful excesses, to work their way through these and to find their own destiny despite their handicaps. Self-improvement is neither pleasant nor easy, especially where one is young, inexperienced and alone. And, where heroines exhibit unhealthy or excessive interests in anything that diverts them from their paths of virtue or usefulness, the correction may frequently be painful. Thus most of the novels are, to a greater or lesser degree, filled with references to both physical and psychological ill health. This thesis examines how Austen used these illnesses, accidents and deaths in the various novels, both in the development of plot, as well as in the development of the character of the heroine in each instance.

The study intends to compare the impacts of two different teaching approaches helping students achieve the competency indicators in the national standards concerning the nature of science (NOS-CI). The researcher choose two NOS-CIs which include “3-1-0-1: To learn how to describe what has been observed”, and “3-1-0-2: To believe that one can often come up with new findings with careful observation” as the teaching goals. Through students’ using scientific vocabularies and drawing pictures, it may reflect students’ achievement of the NOS-CI. The total teaching treatment is two elementary school class periods. Subjects are two classes of fourth graders with a nonequivalent pretest-posttest control group design. The experimental class (with checklist plus digital camera, CDC) has 29 students and the control class (with mere hands-on operation, MHO) 30 students. There are each 12 students interviewed for both groups. The results of this study show that, in terms of 3-1-0-1, both CDC and MHO treatments have significant teaching effects upon students’ NOS-CI achievement. However, as to the two-months-after-posttest delayed test, CDC remains a significant effect while MHO does not. In terms of 3-1-0-2, the CDC does have up to 34.5% of students reflecting new findings by students’ self-report. It seems to researcher that CDC outperforms MHO, too. Due to the few valid samples selected, researcher recommends a further research with more samples in order to confirm such a result. Nevertheless, both groups of students expressed during the interview that group discussion does stimulate more new findings rather than individual investigation. Finally, both CDC and MHO have no significant impact upon students’ attitudes toward science. Yet, CDC does promote students’ learning motivation. Research recommendations and teaching implications will be discussed in thesis.

This study explores whether the environment has water will have difference in restoration performance. Use four groups of environments as sample areas, such as, "natural environment", "natural environment with water", "urban environment", and "urban environment with water". Through the heart rate, blood pressure, heart rate variability, POMS, RCS scale as indicators, explore the restoration effect result from water elements, and hope to provide the basis academic foundation for selecting the place for natural healing in Taiwan. In the comparison of " natural environment with water" and "natural environment", the difference of the healing effect is mainly in physiological parts, such as heart rate, autonomic nerve activity. The restoration performance of " Natural environment with water" is better than "natural environment". On the other hand, weather the urban environment has water, the difference in restoration performance is mainly in psychological parts, there is a significant difference in vitality, self-respect, and distance dimension in recovery scale. Summarizing the research results, the proper allocation of water elements in the city can greatly improve the healing and recovery effects, and bring positive effects to human emotions. And the healing effect is close to the "natural environment with water". It can be proved that set up the water bodies into the urban environment is the right choice to improve the health of urban residents. Through this experiment, we can also find that the physiological restoration effect brought by the healing activities is greatly affected by the exercise. For the young people who lack exercise habits, after 30 minutes of walking activities, the value of LF and HF will fall, caused by physiological fatigue and stress. This point should be taken into consideration in the planning of healing activities.

The Blyde Canyon Nature reserve displays its natural beauty for most National and International visitors all over the World. The region is renowned for its high rainfall and misty weather, which enhances the natural beauty of the area. Because of the mist belt effect, the area is one of the largest commercial forestry areas in South Africa. Baboons also seek after the topography and vegetation type (Northeastern mountain sourveld) that is typical of this area and numerous baboon troops occur in this region. This combination is often the cause of conflict between baboons and humans. The need arise for these baboons to be studied and managed as a component of this very important ecosystem. The main aims of the study were firstly to identify a natural ranging baboon troop, to habituate them and gather data regarding home range sizes, troop sizes, densities and seasonal food selection and secondly to give a detailed habitat description and vegetation map of the troop's home range. The baboon activity data was collected in 15-minute intervals over a one year period on a troop at Bourke's Luck. This included all activities such as walking, social, foraging, and resting. The food parts selected as well as the species foraged on was identified. Numerous statistical methods were used on the baboon data such as; the Shapiro Wilk test, Spearman rank-order correlation, ANOVA, and the Kolmogarov-Smirnov two sample test. There was a positive correlation between home range areas and troop sizes and the baboons preferred certain habitats above others during different seasons. To give a detailed habitat description of the troop's home range, 50 sample plots was stratified-randomly distributed in order to include all the different stratification units. a TWINSPAN classification, refined by Braun-Blanquet procedures was carried out on the Bourke's Luck section that included the baboons home range. 13 Plant communities, which can be grouped into 7 major community types were identified. This study resulted in the ecological interpretation of baboon activities related to the ecological interpretation of the vegetation in the baboon troop's home range.

Abstract This research investigated the learning effectiveness of the computerized instruction of the “Nature” domain in three different types of learning environments. Quasi-experimental design was employed and 134 junior high students of the 7th grade from four normalized classes in the central part of Taiwan participated in this study. Two classes assigned to e-Learning in the e-classroom, one class to web-based learning in the computer classroom, and one to web-based instruction in the traditional classroom. Those participants learned the topic “Nutrition” last for three weeks. This research adopted mainly quantity data and supported with quality data. The quantity data included the scores of SAM-WATA, ACALE and MyELS, and the quality data included the students’ interview and the researcher’s diary. The results revealed the three different groups’ achievement increased significantly (p<.01). The group of e-classroom learning had more progressive than the traditional classroom and the computer classroom learning. The results of ACALE showed both the e-classroom and the traditional classroom groups had significantly increased on computer anxiety, computer preference, learning motivation and learning habit, respectively, and the latter two attitudes in the traditional classroom group were better than in the e-classroom group. The results of MyELS showed both the e-classroom and the traditional classroom groups had significantly increased on learning attitude, task orientation, classroom ambiance, learning participation, cooperation, teacher support, equal relation and instruction activity. The computer classroom group had also significantly increased except classroom ambiance attitude, and was better than the traditional classroom group on learning attitude. Finally, we suggest that teacher can use the strategy of cooperative learning, multi-media, hyper-link and web-based test, ask the helps from administrative office, improve teacher’s PCK and retain a good interaction among the students and the teachers to perform the computerized instruction to the domain of “Nature” smoothly. Keywords: computerized instruction , classroom environment , e-classroom , e-Learning , learning effectiveness , learning motivation , cooperative learning , web-based test

A gram-positive, ovoid, diplococoid bacterium tentatively identified as Enterococcus sp. was isolated from diseased Macrobrachium rosenbergii farms in the southern Taiwan from July to October, 1994. The diseased prawns displayed poor growth, anorexia, inactivity, opaque and whitish musculature, and mortality. In histological preparations, melanized hemocytic granulomas were seen in the connective tissue around hemal sinuses together with hemocytic aggregation in necrotic musculature. Five isolates of diplococci were collected from diseased prawns at four farms. They were evaluated for 93 characteristics including morphology, physiology, biochemistry and sensitivity to antibiotics. The results indicated that the isolates belonged to an Enterococcus sp. closely related to Enterococcus seriolicida (synonymy with Lactococcus garvieae). Experimental injection of 3×105 cells of this strain (KM002) into the ventral sinus of the prawn cephalothorax caused 100% mortality in 11 days, and induced muscular necrosis and hepatopancreatitis, gross signs and histopathology similar to those observed in the naturally infected prawns. It was concluded that this Enterococcus sp. was the etiological agent associated with mortality of the farmed diseased prawns.The growth of this pathogenic strain (KM002) of Enterococcus sp. was examined in brain heart infusion broth (BHIB) at different pH levels, temperature, and NaCl concentrations. It grew at pH of 3-10, temperature of 5-45℃ and 0.5-6.5% of NaCl concentration with optimal level of pH 7-8, 25-30℃ and 0.5-1.0% NaCl concentration. M. rosenbergii was challenged by injection of either 1×107 or 2×106 cfu/prawn of KM002 previously incubated under these various conditions for 24 h, and monitored for pathology for 168 h. The results indicated that the pathogenic strain incubated at pH level of 7 and 8, temperature of 27℃ and 30℃ and NaCl concentration of 0.5% and 1.0% caused higher mortality of M. rosenbergii. M. rosenbergii were challenged with an Enterococcus sp. (KM002). Challenge doses and conditions of pH, salinity and temperature were varied to determine the influence of environmental factors on the development of disease and mortality. In pH tests, the onset of mortality was earlier and the cumulative mortality was higher at pH 8.8-9.5 than at pH 4.6-5.2 and 7.5-7.7. In salinity tests at two challenge doses (1×106 and 2×107 cfu/prawn), onset of mortality was earliest at 15 ppt and cumulative mortality was low at 5 ppt and 10 ppt. In temperature tests at pH 7.2-7.5 and at two challenge doses (2×107 and 4×107 cfu/prawn), the onset of mortality was earliest at 33-34℃ and total mortality occurred at 27-28℃ and 33-34℃. Reducing the challenge dose to 5×104 cfu/prawn gave lowest survival at 33-34℃ group. In similar temperature tests but at pH 8.8-9.5, onset of mortality was accelerated and there was 100% death for all the high challenged groups. At low challenge doses, mortality was lower but still highest in the 33-34℃ group. Results indicated that mortality of M. rosenbergii caused by this Enterococcus sp. was exacerbated by higher temperature of 33-34℃ and higher pH level of 8.8-9.5. By contrast, low salinity appeared to have a beneficial effect on survival.The total hemocyte count and phenoloxidase activity were examined for M. rosenbergii that was reared at different conditions of pH, salinity and temperature and feeding rate. In pH tests, the total hemocyte count was significantly higher at pH 7.5-7.7 than at pH 9.0-9.5 (p<0.05) and pH 4.6-5.0 (p<0.1). The hemocyte phenoloxidase activity was significantly different among different pH levels (p<0.05) with an order of pH 7.5-7.7 > pH 4.6-5.0 > pH 9.0-9.5. In temperature tests, the total hemocyte count was significantly lower at 33-34℃ than 27-28 and 30-31℃ (p<0.05). The hemocyte phenoloxidase activity was significantly different among different temperature levels (p<0.05) and was 30-31℃ > 27-28℃ > 33-34℃. In salinity tests, total hemocytes count was directly related to salinity level. Hemocyte phenoloxidase activity was significantly higher at 5 and 10 ppt than at 0 and 15 ppt (p<0.05). In temperature tests at a same feeding rate (0.6%), the total hemocyte count was significantly higher at 27-28℃ than at 20-21℃ and 33-34℃ (p<0.05). Hemocyte phenoloxidase activity was significantly higher at 27-28℃ than at 20-21℃ and 33-34℃ (p<0.05). In the test of different feeding rate at 27-28℃, the total hemocyte count was significantly lower at 0.1% than at 0.5% (p<0.05), 1.0% and 1.5% (p<0.1). Hemocyte phenoloxidase activity was significantly lower at 0.1% of feeding rate than those above 0.5% (p<0.05). Results indicated that the total hemocyte count and phenoloxidase activity of M. rosenbergii varied at different pH, temperature, salinity levels and different feeding rates. It was concluded that the phenoloxidase activity rather than total hemocyte count is considered to be a healthy parameter of M. rosenbergii.

The purpose of this study is to understand whether forest environments of different densities can provide human psychological benefits, and which density forests have the best physiological and psychological benefits. Therefore, this study selected the permanent test plots of the Cryptomeria plantation from the No. 173 of the Xitou Tract Area of National Taiwan University Experimental Forest. We select three kinds of stand densities as the study area, high-density stand (10,000 N/ha), medium-density stand ( 1000 N/ha) and low-density stand (400 N/ha) and the test site was used as the control group with the second parking lot. Each subject (N=76) were asked to sit at the plot for 15 minutes. The physiological aspects were measured by heartbeat, blood pressure and heart rate variability. Psychological aspects use the Profile of Mood State (POMS) Subjective vitality Scale (SVS) and Restorative Components Scale (RCS) and Semantic Differences Scale (SD) as psychological measurement tools. the temperature, humidity, wind speed, air pressure, illuminance and negative ion amount in the objective environmental factors are monitored and presented as PMV indicators. The results showed that there were no significant differences in the environmental factors (PMV index, illuminance, negative ion). Japanese Cedar (including high, medium and low densities) can significantly reduce the number of heartbeats, and the medium-density stand is significantly better than the control group. In terms of POMS, high, medium and low density stands are significantly reduced in confusion, fatigue, anger, tension and frustration. The high-density stand and the control group has a significant increase about vigor. About the therapy effect, high-density stand were significantly better than the control group in confusion and anger, and the vigor was significantly better than the medium-density stand. Fatigue, tension and frustration were significantly better than medium-density, low-density and control group. In terms of SVS, there were significant increases in high, medium and low density stands, and there was no significant difference between each stands. About RCS, the three kinds of stands were significantly better than the control group in extend and fascination, and there was no significant difference between the stand density. In the SD, the medium-density stands were significantly better than the control group in the satisfy, rich, neat and tidy,and the high and medium-density stands were significantly better than the control group in the beautiful and friendly. High, medium and low density stands were significantly better than the control group in natural, quiet, safe and comfortable.

Abstract School: The Graduate Institute of Fine Arts of Chinese Culture University Thesis: ''The Different Expressive Ways of the Same Nature''-The Presentation of light and Shadow in the Chinese and Western Paintings Thesis Advisor: Professor Sun Jia-chin Graduate student: Yang Sheng-an I. The purpose and motivation of my study It is quite obvious that the whole artistic expression differ between the Chinese andWestern paintings. I, in exploring into the fields of the Chinese and Western paintings,come to find out a very important issue-"light and shadow." To know the reason why the recognition and expression of the mentioned-above issue are so differentis the main motivation of my study. II. Methodology This thesis proceeds in a step-by-step procedure. First, I make a comprehensive study on the Chinese and Western aesthetics, and then, I present "light and shadow" as the central structure of my thesis. By so doing, I can analyze the difference and sameness of the expression of light and shadow in the Chinese and Western paintings through focusing on those aspects ranging from "thought" to "expression," in an attempt to manifest the width and depth of my analyses. III. The results of my study 1. The thoughts of the Chinese aesthetics point to the spirit of human beings whereas the thoughts of the Western aesthetics point to the outer world of human hearts. 2. The foundation of the Chinese paintings lies in the Chinese life philosophy, which advocates expressing Nature and focusing on symbolism. In contrast, the foundation of the Western paintings lies in science, which advocates representing Nature and focusing on realism. 3. In the Chinese paintings, there are no such things as concrete visual focus, rigid distance perspective, and a world reflected through the fixed light sources. By contrast, the Western paintings emphasize scientific perspective and light-color analyses, thereby creating a world reflected through the fixed light sources. IV. Retrospection and outlook Nowadays, the exchanges of the Chinese and Western arts and cultures occur frequently. How to blend the Chinese and Western arts together seems to become the task a modern art creator should face. I hope that I can better understand the differences between the Chinese and Western paintings during the period of writing my thesis. It can give me an opportunity to retrospect and self-criticize my own creative works, thereby finding the direction and destination of my future artistic creation.

Une des questions centrales de la métaéthique est celle de savoir si les propriétés morales sont des propriétés naturelles ou non-naturelles. Ce mémoire fait valoir que nous ferions bien de remettre en question une constellation d’arguments en faveur du non-naturalisme moral : l’argument de la question ouverte, l’intuition normative et l’argument du gouffre. L’influent argument de la question ouverte de Moore, d’abord, ne soutient le non-naturalisme que s’il commet une pétition de principe. L’intuition normative commet ou bien le sophisme d’inférer sur la base de sa différence spécifique qu’une chose n’appartient pas à un genre donné, ou bien sous-estime la panoplie de propriétés naturelles qui possèdent les caractéristiques censées être distinctives des propriétés morales et normatives. L’argument du gouffre, quant à lui, sous-estime l’ubiquité du fossé logique et conceptuel censé marquer une discontinuité métaphysique profonde entre les domaines normatif et naturel.
One of the burning questions among metaethical realists is whether moral facts and properties are natural or non-natural. In this thesis, I argue that we should treat a family of arguments for non-naturalism with considerable scepticism: the Open Question Argument, the Normative Intuition, and the argument from the Is-Ought Gap. Moore’s famous Open Question Argument only supports moral non-naturalism if it begs the question against the modest (non-reductionist) naturalist. As for the Normative Intuition, it either commits the fallacy of inferring on the basis of a thing’s specific difference that it does not belong to the genus it putatively belongs to, or it underestimates the breadth of natural properties that possess the features which non-naturalists allege are distinctive of moral and normative properties. The argument from the Is-Ought Gap, for its part, underestimates the ubiquity of the logical and conceptual gap that allegedly marks a deep metaphysical discontinuity between the normative and natural domains.

The study aims to investigate the effects of dietary different in encapsulated and unencapsulated nature digestive enzymes on growth and immune responses of Epinephelus coioides. In experiment used agar and gelatin encapsulated with different proportions of natural digestive enzymes and unencapsulated treatment. The diets were fed to triplicate of group of orange-spotted grouper with 4.55±0.55g. The results indicated that effects of encapsulated and unencapsulated neither affect growth and immune response. Growth of digestive enzymes assist digestion and absorption of corn protein makes no significant difference in results. The terms of encapsulated digestive enzymes in the diets to add the amount of 0.10% is the optimum proportion , weight gain was 525% and the terms of directly adding digestive enzymes in the feed to add the amount of 0.05% is the optimum proportion, weight gain was 531%. The results showed that after adding digestive enzymes, lysozyme activity and the generation rate of superoxide anion, 0.15% is the optimum propotion.

The purpose of this study was to exam the differences of the nature of commitment among substitute players of different patterns of commitment determinates, comprised of sport enjoyment, involvement alternatives, personal investments, social constraints, involvement opportunities, and social support. The differences of sources of confidence among starters and substitute players were also tested. Participants were 205 Division I college basketball players. Cluster analysis revealed 4 types of substitute players, namely, the almighty, the wholehearted, the involuntariness, and the indifference. ANOMAs showed that the almighty and the wholehearted were higher than the involuntariness, who was subsequently higher than the involuntariness, in the “want to” commitment (F(3,133) =27.48,p<.05). For the “have to” commitment, the almighty and the involuntariness were higher than the wholehearted as well as the indifference (F(3,133) =10.06,p<. 05). MANOVA also found that starters and the first-round substitute players, comparing with the second-round substitute players, perceived coaches ' s leadership and social supports as more salient sources of their confidence in basketball. These results suggest that some substitute players may have gradually lost their commitment in basketball and the coach should pay more attention helping their substitute players to identify their roles on the team and enhance their self-worth.
