Full textTerrestrial laser scanners (TLS) have been common in geodetic measurements for over 10 years. The technology is developing rapidly and specialized instruments are launched constantly. One type of these specialized TLS instruments are hand-held laser scanners. They are designed primarily to generate point clouds of spaces and small objects where the traditional tripod mounted laser scanner has difficulties to scan. When the hand-held laser scanners are relatively new, the research on the instruments is limited, and the lack of standardized control methods. With that in mind it is important to study the instruments. In this thesis the hand-held laser scanner FARO Freestyle X was investigated on how well the handheld laser scanning technology really is and what limitations the instruments have. This was done by comparing point clouds from FARO Freestyle X with reference point cloud generated by Leica's multi-station MS50. To study the instrument a number of parameters was investigated such as scanning distance, ease of use, time and performance. These parameters were considered to be sufficient basis for conclusions about the instrument's advantages/disadvantages and limitations. The result of the point cloud comparison from the short distance showed deviations around 10 mm and then increase to few centimeters at longer distances. Volume limitation control showed no differences compared to the scanning from short distance. This means that moving the instrument does not affect the results significantly. The instrument's Achilles' heel is the noise that occurs when scanning from longer distances, about 30 mm deviations. Even the type of object affects the noise. The noise on the wall showed the greatest deviation while the noise on the table indicated the lowest results. The repeatability showed good results visually and had similar deviations. The instrument has a good ability to recreate objects when the resolution test demonstrates good performance. Main advantage of the instrument is its effective documentation of smaller objects, but also some larger areas where the uncertainty of centimeter-level is required. The ease of use can be described as good and the colored point clouds takes visualization to a new level. The results of the study show that the hand-held laser scanners can, potentially, challenge the traditional laser scanner.

Full textLiDAR (Light Detection And Ranging) é um sistema baseado nos princípios de Deteção Remota que permite medir distâncias com base no tempo da trajetória da radiação laser, desde que é emitida pelo aparelho até que retorna ao recetor depois de ser refletida numa superfície sólida. A aplicabilidade deste sistema é abrangente a várias áreas da engenharia e prende-se com a capacidade que o mesmo tem de recolher e armazenar dados tridimensionais em forma de nuvens de pontos de qualquer objeto sólido sobre a superfície terrestre. No sector florestal, este sistema permite estimar características dos povoamentos e digitalizar uma extensa área de floresta, de uma forma automatizada, rápida e com detalhe na ordem dos milímetros. O objetivo do presente trabalho é avaliar a capacidade do sistema LiDAR na individualização da árvore comparando as coordenadas estimadas obtidas com dois métodos LiDAR - HMLS (Held-Hand Mobile Laser Scanner) e TLS (Terrestrial Taser Scanner) - com as coordenadas obtidas com GPS sub-métrico, pelo método tradicional de campo, num ensaio clonal de Eucalyptus globulus Labill. com 10 anos de idade. O presente estudo serviu também como primeira abordagem ao desempenho dos dois métodos LiDAR na obtenção de diâmetros às várias alturas do tronco, recorrendo aos algoritmos disponíveis no software R. Para a deteção das árvores individuais, os resultados demonstraram que, em média, o método TLS detetou 65,1% das árvores, enquanto o método HMLS detetou 44,7% das árvores, para todas as parcelas de estudo. Comprovou-se ainda que o levantamento com HMLS só é vantajoso para terrenos regulares e percursos retos. Concluiu-se que deve ser efetuada uma melhoria nos processos associados à utilização do algoritmo SLAM (Simultaneous Localization And Mapping) e salientou-se a importância de utilizar pontos de referência em campo para a obtenção de nuvens de pontos de melhor qualidade

Full textThis bachelor’s thesis aims to examine different conceptual solutions of transmission lines for a winch-based wave power plant. The different concepts are; a rope of the material HMPE (High Modulus Polyethylene), a transmission line based on KONE Ultrarope and a transmission chain based on elastomeric bearings. These have then been divided in that order into concept A, concept B and concept C. The analyses of these are based on existing information and knowledge. From these concepts, concept A has been chosen to be further analyzed and optimized. Concept A was chosen by following the method of a Pugh matrix. The modeling software Solid Edge has been used when developing concepts, A and B. Concept A was optimized by designing a drum that minimize abrasion, maximize the life of the rope and was also adjusted for reaching the specific requirements.

Full textCompetition between manufacturing companies is constantly increasing and this causes high demands on product quality and ability to deliver products in time. For companies to be able to reach these goals it is necessary to work with development and continuous improvements and respond to the current pace of the market. This can be achieved in different ways, but a common method is to work with improvement methodologies. Selecting which improvement methodologies to use depends on a company’s manufacturing, knowledge, and resources. Many organisations find it difficult to choose improvement methodologies for their particular organisation and ask the question: “Which method is best suited for our organisation?”. The goal of this study is to examine whether and how Lean Production and Theory of Constraints can be utilized in companies with high-mix low-volume production. By performing a literature review and a case study the following questions have been answered: 1) how Lean production and Theory of constraints are utilized in a HMLV production system and how they can be combined, 2) how the production flow is controlled according to Lean Production and Theory of Constraints to improve the efficiency of a production process in a HMLV company, 3) what personal paradigms and policys arise according to Lean Production and Theory of Constraints in HMLV company and what the relationship between these and quality is. Results from the literature review and case study show that Lean Production and its tools are possible to use in a combination with Theory of Constraints in HMLV companies with some exceptions. However there is no exceptions saying that Lean Production and its tools combined with Theory of Constraints can not be utilized in HMLV companies. These exceptions only need to be adjusted for HMLV production. The results also showed that standardized work in a production process plays a crucial role when combining Lean production with Theory of Constraints. Standardized work contributes to facilitation of further development and implementation. The results show that the production flow can be adjusted using methods from Lean Production and Theory of Constraints, and that this is done best by combining these two methodologies. Furthermore, the results showed that in many cases new investments in the form of new equipment are not necessary. This assumes that bottlenecks, such as personal paradigms and policies are identified. The results showed that quality is directly linked to these two bottlenecks and that an investment in management is preferable.

Full textDental Caries is an infectious disease naturally multi-factorial that begins in the childhood, able to spread its intensity and prevalence according to the mouth ambient conditions of each host. The risk of the patients to develop, in some time of their lives, carious lesions can be measured through a complex analysis using health determinant factors and other specific factors of the health-disease process. Since the dental caries forward diagnostic as well as the review of the auxiliary determinant factors of the dental caries danger evaluation, the treatment becomes simpler, less invasive and costing lower. It has been quite broad-casted lately the use of lectins to diagnose and to prevent some diseases. When dealing with dental caries disease, through many years this strategy has been explored still inceptively. Looking through this perspective, the goal of this trial was to investigate the biotechnological potential of the red marine alga Hypnea musciformis (HML) applied to Dentistry. It is about an explanatory-experimental study of quantitative approach through the health questionnaire and data statistics analysis. The research makes reference to some comparative analysis of salivary tests and the cariogenic activity in twelve year-old students and it searches to evaluate the biotechnological potentialities of the lectin from the red marine alga Hypnea musciformis (HML) in the diagnose and prevention of the dental caries. The concentration area of this trial was the macromolecules/ lectin biotechnological application. In the present trial were compared obtained results through the application of the conventional clinical exams to dental caries and salivary tests of dental caries activity pointed by the CARIOGRAMÂ program in association with lab analysis using specific lectins. From this trial, it has been concluded that, about lectins as a biotechnological potential to prevention and diagnose of the dental caries, it has been noticed that there is recognition of resident glycoconjugate on pacifier saliva of high and low risk observed in immunofluorescence pattern. The results showed that the tested lectin has the capacity to intervene on the bacterial growth in a negative way, it is being distinguished statistically (p<0,01) in relation to control group of saline and BSA. However, inhibition studies of the microbial biofilms using the HML are being programmed to evaluate the using possibility of these protein as biotech input to be used for dental caries prevention. It could be said also that the obtained results by the use of HML in the antimicrobial activity were promising, showing that this lectin has presented antimicrobial activity even on very small amounts. As to the use of these protein in the biofilm formation and developing there was no characteristic pattern.
A cÃrie à uma doenÃa infecciosa de natureza multifatorial que se inicia na infÃncia, podendo aumentar de intensidade e prevalÃncia de acordo com as condiÃÃes do ambiente bucal de cada hospedeiro. O risco do paciente em desenvolver, em algum perÃodo de seu ciclo de vida, lesÃes cariosas pode ser medido atravÃs de uma anÃlise complexa que utiliza os fatores determinantes da saÃde e outros fatores especÃficos do processo saÃde-doenÃa. A partir do diagnÃstico precoce da doenÃa cÃrie, assim como anÃlise dos fatores determinantes auxiliares da avaliaÃÃo do risco de cÃrie, o tratamento torna-se mais simples, menos invasivo e de menor custo. Tem sido bastante difundida ultimamente a utilizaÃÃo de lectinas para diagnÃstico e prevenÃÃo de algumas doenÃas. Em se tratando da doenÃa cÃrie, ao longo de muitos anos, essa estratÃgia tem sido explorada ainda de forma incipiente. Nesta perspectiva, o objetivo deste trabalho foi investigar as potencialidades biotecnolÃgicas da lectina de alga marinha da espÃcie de Hypnea musciformis (HML) aplicadas à odontologia. Trata-se de um estudo explicativo-experimental de abordagem quantitativa atravÃs de questionÃrio de saÃde e anÃlises estatÃsticas de dados. A pesquisa faz referÃncia à uma anÃlise comparativa de testes salivares e atividade cariogÃnica em escolares de 12 anos de idade e a busca avaliar as potencialidades biotecnolÃgicas da lectina de alga marinha da espÃcie de Hypnea musciformis (HML) no diagnÃstico e prevenÃÃo de cÃrie dentÃria. A Ãrea de concentraÃÃo deste estudo MacromolÃtulas / AplicaÃÃo BiotecnolÃgica de Lectinas. No presente estudo, foram comparados os resultados obtidos atravÃs da aplicaÃÃo de exame clÃnico convencional para cÃrie e testes salivares de atividade cariogÃnica apontados pelo programa CARIOGRAM em associaÃÃo com anÃlises laboratoriais com a utilizaÃÃo de lectinas especÃficas. A partir deste estudo, concluiu-se que, em se tratando do uso de lectinas como potencial biotecnolÃgico para a prevenÃÃo e diagnÃstico de cÃrie dentÃria, percebeu-se que hà reconhecimento de glicoconjugados presentes na saliva de pacientes de alto e baixo risco observados em padrÃo de fluorescÃncia. Os resultados demonstram que a lectina testada tem a capacidade de interferir no crescimento bacteriano de forma negativa, sendo estatisticamente significante (p<0,01) em relaÃÃo aos grupos controle de salina e BSA. Entretanto estudos de inibiÃÃo da formaÃÃo de biofilmes microbianos utilizando a HML estÃo sendo programados, para assim avaliar a possibilidade de utilizaÃÃo dessas proteÃnas como insumos biotecnolÃgicos a ser utilizados para prevenÃÃo da cÃrie dentÃria. Pode-se ainda afirmar que os resultados obtidos pelo uso de HML na atividade antibacteriana foram promissores, mostrando que esta lectina apresentou atividade antibacteriana mesmo em quantidades muito pequenas. Quanto ao uso destas proteÃnas na formaÃÃo e desenvolvimento de biofilmes, nÃo houve padrÃo caracterÃstico.

Full textThis thesis covers investigations on the properties of ultrahigh-molecular-weight (UHMW) polyethylene fibers for use of manufacturing braided fiber ropes for conveyor and hoisting applications. The importance of synthetic fibres for conveying applications has increased during the last years. Due to the low density and bending stiffness at a strength that is comparable to steel, ropes made from high-strength UHMW polyethylene fibres have found their ways into several shipping and off-shore applications. The basic aptitude of UHMW polyethylene fibres to be used in applications like cranes, elevators and winch applications has already been proven in scientific works. Within this thesis, selected UHMW polyethylene fibres are investigated to determine how much their differing property profiles do influence their aptitude to be used in technical applications with cyclic bending loads and for which potentials for fields of application they might be appropriate. Starting with a short overview on the history of synthetic fibres and the use of such fibres in technical applications, manufacturing processes and properties of these fibres are to be compared. Further, fibre ropes, made from the selected fibres, are going to be investigated concerning their tensile strength, behaviour in cyclic bend-over-sheave tests and their aptitude to increase the strength by thermosetting. Occurring effects are going to be analysed and related to the properties of the yarns. A competitive view on the prices of the yarns regarding their portion of the total costs of rope manufacturing is finalising this work

Full textAccording to a study by Gallup (2017), only 14% of all employees in Sweden experience engagement in relation to their work. This creates a negative impact from an economic aspect but also on the work environment. With this as a starting point, the purpose of this study was to investigate the relationship between SKR's measurement tool for sustainable employee engagement (HME) and what the research believes has the most significant impact on motivation. Furthermore, the study also intended to study the characteristics of employees in companies with a high commitment index and see how this could be measured. The theory chapter highlights the theory of quality development, the collaboration based on Velten et al. (2017) three pillars, which are considered to be the basis for job satisfaction and finally, the factors that, according to research, are considered to have the most significant impact on motivation (meaning, self-determining competence and influence). The sample for the study was working groups that measured high value on the engagement index 2020. The study was by design a case study and has used several methods in the data collection. A qualitative part of the study was conducted by reviewing the HME model's index for sustainable employee engagement (HME) and four interviews. In the quantitative part, a questionnaire study was conducted. The results show that three out of six statements in the measurement tool HME are not considered to support research on motivation. Employeeship in organizations with a high HME can be summarized through three main areas with two to four sub-areas. The study concluded that these are characterized by factors that can be linked to Velten et al. (2017) three pillars and the factors that, according to research, have the most significant influence on motivation. The qualitative study is validated through the questionnaire study, which also shows that employeeship can be measured through the study's tool.

Full textThe report is based on various categorization methods that have been developed to increase the level of service in the long term. The case company has recently expanded, which has contributed to them no longer being able to meet the demand. The purchasing strategies they previously used are no longer sufficient for the new sales volumes. With long delivery times from factories in Asia, the intervals between stock refills are getting longer, which requires foresight. Using empirical data, student literature, non-fiction and observations, the report explains how the business can be improved through a case study. Calculations, formulas and tables are based on student literature and scientific articles. By starting from proven theories, the business's inventory management can be improved. With the help of observations during the visit to the case company, mapping of the business and its strategies could be completed, which led to the report's purpose and issues. By structuring the data according to the different methods, together with visual aids such as diagrams and graphs, the result could be shaped. The results were then analyzed to draw conclusions about whether there is any correlation between the theory and the report's results. The analysis highlights how categorization of the methods is used to increase the level of service. In addition, the advantages and disadvantages of the different methods are analyzed. Discussion about which categorization is most suitable in the current situation and for the future is then highlighted. There are also discussions about different forecast models and how to proceed to improve inventory management and raise the level of service. The validity and reliability of the report are also discussed in order to be able to identify how reliable the report is and whether it actually measures what it wishes to measure. The report states that FSN is the best categorization for the fall company. By analyzing forecast models based on demand from the categorization, a purchasing strategy for the company in the future is estimated. The future purchasing strategy is based on quantitative models, which is based on historical data that the case company currently lacks. In addition to future purchasing strategies, working methods with new products as well as improvement proposals with the work of categorization models are proposed. Finally, all recommendations are summarized for a simpler understanding of the report's discoveries.

Full textInvestors and companies can choose between multiple pricing models to predict the price of shares. With the known one factor model CAPM, researchers have developed a model that consider more than just the market factor. This resulted in the creation of the Fama & French three factor model (FF3), which also includes the size factor SMB and the value factor HML. The purpose of the study is to evaluate two pricing models, CAPM and FF3, to assess their performance when evaluating expected returns. Previous research often deal with international markets and model performance of portfolios. We study selected individual Swedish shares for January 2011 to December 2015 by replicating previous research by Bartholdy & Peare (2005). Selected companies are analysed by regressions for the models to be able to evaluate these separately, and to see if FF3 has a higher degree of explanation than CAPM for individual Swedish shares. The result of the study shows that both CAPM and FF3 are applicable for selected individual Swedish shares. There is a difference in the adjusted degree of explanation between the models but it is marginal. In conclusion, the study contributes with the knowledge that CAPM and FF3 can be applied to individual Swedish shares, but there is no major difference in the choice of these two models.

Full textMy dissertation includes three chapters on the value premium. In the first chapter, I study whether seemingly innocuous decisions in the construction of the original HML portfolio (Fama and French, 1993) affect our inference on the value premium. I find that the value premium is dramatically smaller than we thought. In sample, the average estimate of the value premium is 0.09% per month smaller than the original estimate of the value premium. Out of sample, however, the difference is statistically insignificant. The results suggest that the original value premium estimate is upward biased because of a chance result in the original research decisions. In the second chapter, I propose an estimate for intangible assets and growth opportunities and examine if this estimate improves book-to-market equity as a measure of value. I find that portfolios sorted on book equity plus the estimate to market equity have lower returns than portfolios sorted on book-to-market equity. The results suggest that intangible assets and growth opportunities diminish book-to-market equity as a measure of value because investors value intangible assets and growth opportunities in an overly optimistic way. In my third chapter, I simultaneously study nine explanations of the value effect to better understand what the dominant value explanation is. I find that duration accounts for most of the value effect and that the eight other explanations account for a negligible part of it. The results suggest that duration is the dominant explanation of the value effect

O mel de abelha tem uma imagem de ser natural e saudável, entretanto, muitos dos méis consumidos hoje são produzidos em ambientes poluídos por diferentes tipos de contaminação alterando, com isso, suas características mais nobres. Nesse estudo a contaminação por metais pesados tais como Zn, Cd, Pb e Cu é avaliada para 20 amostras de mel de abelha produzidas no estado de Pernambuco utilizando a técnica de voltametria de redissolução anódica de pulso diferencial (DPASV, do inglês Differential Pulse Anodic Stripping Voltammetry) em eletrodo de gota pendente de mercúrio (HMDE, do inglês Hanging Mercury Drop Electrode). A formação de compostos intermetálicos entre Zn e Cu na superfície do eletrodo durante a etapa de préconcentração impede a determinação simultânea dos quatro metais na matriz orgânica mineralizada. Para a determinação de Zn utiliza-se uma solução-padrão de Ga(III) e o Cu é determinado em um potencial de deposição menor que o requerido para a redução do Zn, permitindo a determinação dos quatro metais por dois experimentos de DPASV realizados consecutivamente na mesma amostra. As faixas de concentrações de metais pesados encontrados nas amostras analisadas foram de 1,283 – 4,312 mg.g-1 para Zn, 0,168 – 0,645 mg.g-1 para Pb e 0,170 – 1,426 mg.g-1 para Cu. A presença de Cd nas amostras não foi detectada. O método apresentou altos níveis de repetitividade e ausência de viés em concentrações acima de 0,200 mg.g-1. De acordo com esses resultados, observa-se que o mel produzido em Pernambuco é de boa qualidade, embora uma das vinte amostras analisadas tenha apresentado teor de Pb acima do limite estabelecido por legislação vigente. Acredita-se que essa amostra pode ter sido contaminada durante o processo de transporte do mel já que este foi envasado em local distinto do apiário de origem. Para as demais amostras, as concentrações de metais pesados estão dentro dos parâmetros aceitáveis.

Full textThe present work decribes the production and characterization of the first antibodies against triacetone triperoxide (TATP), a highly sensitive and improvised (non-commercial) primary explosive. Crucial to this work was the synthesis of a TATP-related hapten that mimics almost perfectly the typical nonagonal structure of TATP with its three peroxide and six methyl groups. Advantageously, it has an additional carboxylic acid group, which provides a conjugation site for covalent attachment to proteins. Thus, the TATP hapten could be linked to bovine serum albumin (BSA) to produce an immunogenic conjugate, allowing the successful immunization of two different mammalian species, mouse and rabbit. The in vivo immunization progress was followed by periodically analyzing the animals’ sera using enzyme-linked immunosorbent assay (ELISA). The polyclonal antibodies of both species were remarkably selective to TATP. The affinity of these TATP-antibodies was, however, different between the two species, with the rabbit sera showing an affinity about 5000-fold superior than the murine one. Consequently, the TATP detection limit of 0.01 µg/L was considerably better using the sera from rabbit in contrast to 50 µg/L when mouse serum was used. The working range of the TATP-ELISA with rabbit sera covers more than four decades, calculated from a precision profile. The obtained TATP antibodies from rabbit are now available for applications in highly sensitive detection systems for TATP, which could be employed, among others, in security-relevant areas. The first application was the realization of a TATP-ELISA, which was extensively optimized within the course of this work. Furthermore, the first steps towards the development of a lateral flow assay (LFA) targeting TATP were taken, making conceivable further biosensor platforms based on the newly developed TATP antibodies.

Full textThe finance science, as all sciences, shows an evolutionary line and according to Kuhn (1970), it is marked by shortly periods of knowledge accumulation. However, according to the author, such periods are inserted with scientific revolutions. In other words, the scientific evolution is stamped by revolutions which abandon oldfashioned paradigm and create new ones. The revolution is followed by a period where the researches are guided by the new paradigm and its purpose is strengthen the own paradigm. In other way, the finance science has today a central paradigm well-known by efficiency market hyperlink (EMH) which was witnessed and adopted by the entire scientific community around the 70 s. And since those times, almost entire research done in finance, mainly until the de 90 s, was leaded and done to validate the EMH. This dissertation attempted to evidence that the finance evolutionary line proposed by Haugen (2000) follows the same principle evidenced by Kuhn (1970), and in the present-day, the EMH find itself in a period which precede the scientific revolution which is called by time crisis by Kuhn (1970). This time crisis could weaken the EMH and open a space to create a new paradigm. This way, the proposal of dissertation is to prove how the revolutionary process will happen in finance too, soon after, to prove what would the candidates more inclined to replace the EMH be as a central paradigm in finance. To do so, this work considered only two candidates: the behavioral finance and the chaos theory. To do this analyze it was used the schooling principles nominated by Mckinley, Mone and Moon (2002). Such authors propose that a thought must display a combination of novelty, continuity, and scope to achieve school status in organizational theory. The purpose of this dissertation is to do a theory ransom which intends to show the fragility of the EMH as a central paradigm that orients the finance researches. The dissertation concludes that the current finance faces a crisis, and in this period, the behavioral finance displays the biggest chance to replace the EMH in the near future, however, the chaos theory provides the bigger promise considering a far future
A ciência das finanças, como toda ciência, apresenta uma linha evolutiva que de acordo com Kuhn (1970) é marcada por períodos de breve acumulação de conhecimento. Porém, de acordo com o autor, tais períodos são intercalados com revoluções científicas. Em outras palavras, a evolução científica é marcada por revoluções que abandonam antigos paradigmas e criam novos. Posteriormente à revolução, segue se um período onde as pesquisas são guiadas pelo novo paradigma com o propósito de fortalecer o próprio paradigma. De outra forma, a ciência financeira possui hoje um paradigma central conhecido como a hipótese de mercados eficientes (HME) que foi reconhecida e adotada pela comunidade científica por volta da década de 70. E desde aquela época, quase toda pesquisa feita na área, principalmente até a década de 90, foi guiada, e feita para validar e fortalecer a própria HME. Nesse sentido, este trabalho procurou evidenciar que a linha evolucionária das finanças proposta por Haugen (2000) segue o mesmo princípio evidenciado por Kuhn (1970), e que no momento atual, a HME encontra-se em um período que antecede a revolução científica e que é chamado de período de crise por Kuhn (1970). Esse período de crise, que antecede as revoluções, poderia enfraquecer a HME e abrir espaço para a criação de um novo paradigma. Sendo assim, o trabalho também propõe a evidenciar como que o processo de revolução poderá acontecer em finanças, e em seguida, também propõe quais seriam os candidatos mais propensos a substituir a HME como paradigma central em finanças. Para tanto, o trabalho considerou apenas dois candidatos: as finanças comportamentais e a teoria do caos. Para fazer tal análise, foram utilizados os princípios de escolarização propostos por Mckinley, Mone e Moon (2002). Tais autores propõem que um pensamento tem que possuir três características (novidade, continuidade e escopo) para ser considerado uma escola em teoria organizacional. O propósito do trabalho é de um resgate teórico básico que procura evidenciar a fragilidade da HME enquanto paradigma principal norteador das pesquisas em finanças. Assim sendo, o trabalho conclui que as finanças atuais enfrentam uma crise, e que nesse período, as finanças comportamentais apresentam a maior chance de substituir a HME em um futuro próximo, porém, a teoria do caos fornece uma promessa maior considerando um futuro mais distante

Full textLe génome de cette bactérie contient un chromosome (3.6 Mb), un mégaplasmide (2.6 Mb) et deux plasmides pMOL28 (171 kb) et pMOL30 (234 kb) déjà connus pour porter des gènes de résistance aux métaux lourds.
Nous avons d'abord fait le catalogue des gènes impliqués dans la résistance aux métaux lourds et, ensuite, cherché à mesurer leur expression par deux approches transcriptomiques :RT-PCR et puces à ADN.
L'analyse du génome montre au moins 170 gènes relatifs à la résistance aux ions métalliques localisés sur les 4 réplicons, principalement sur les deux plasmides. Ces gènes codent essentiellement pour des systèmes d'efflux tel que les HME-RND (transport chimioosmotique avec flux de protons à contresens), les ATPases de type P ou encore pour le système de résistance aux ions Cu(II). Dans le génome de C. metallidurans, nous avons identifié 13 opérons qui codent pour des systèmes HME-RND, seuls trois, localisés sur les plasmides, sont surexprimés en présence de métaux lourds. Huit gènes codent pour des ATPases de type P, dont deux appartiennent à une classe dont les substrats ne sont pas métalliques. Deux ATPases appartiennent à une famille spécialisée pour l'efflux du Cu(II) et les quatre autres à une autre grande famille impliquée dans l'efflux des ions Cd(II), Pb(II) et Zn(II). Les analyses transcriptomiques montrent la surexpression des deux premières classes d'ATPases P en présence des métaux lourds. La mutagenèse du gène zntA (mégaplasmide), codant pour l'une des ATPases, provoque une diminution de la viabilité en présence de Zn(II), Cd(II) et dans une moindre mesure de Pb(II), Tl(I) et Bi(III).
Sur pMOL30, la résistance au cuivre implique un groupe de 19 gènes cop codant pour la résistance au cuivre au niveau du périplasme et du cytoplasme, et vraisemblablement pour une forme de stockage du cuivre essentiel. Ces 19 gènes sont surexprimés en présence de cuivre, mais une quinzaine de gènes proches semblent aussi requis pour une expression optimale de la résistance au cuivre.
L'annotation des plasmides a mis en évidence la parenté du plasmide pMOL28 avec le plasmide pHG1 (hydrogénotrophie, fixation du CO2) de C. eutrophus H16 et le plasmide pSym (fixation de l'azote) de C. taiwanensis, et chez pMOL30, la présence de deux îlots génomiques concentrant la plupart des résistances aux métaux lourds. Les puces montrent la surexpression de 83 sur 164 gènes dans pMOL28, et de 143 sur 250 gènes dans pMOL30. Elles montrent aussi que les gènes présents sur les deux plasmides sont davantage surexprimés que ceux localisés sur les deux mégaréplicons. Parmi les gènes surexprimés les plus intéressants du plasmide pMOL30, il faut mentionner des transposases tronquées et des gènes impliqués dans la synthèse des membranes (glycosyltransférases). L'analyse de l'expression des gènes plasmidiens de résistance aux métaux lourds montre la surexpression en présence de plusieurs ions métalliques ajoutés indépendamment et pas seulement par les substrats métalliques de ces opérons, ce qui suggère l'intervention de deux types de régulation dont les gènes correspondants sont aussi localisés sur le chromosome et le mégaplasmide.
Ce travail met en évidence la spécialisation de la bactérie dans la réponse à un grand spectre de concentrations de métaux lourds, jusqu'à la limite majeure de la toxicité observée pour les bactéries mésophiles hétérotrophes. Cette spécialisation correspond bien aux biotopes industriels de divers continents dans lesquels on l'a trouvée.

The major application of HMLS(high modulus lowly shrinks receives gauze) is to be used as the claming gauze in the tire. Due to its high wearing-resistant characteristic, it will cause the chrome-plating on the surface of GR(godet roll) to be worn and damaged. Thereby form the difficulty in maintance adds up as well as the cost. The general GR surface utilizing ratio is only approximately only 15 – 25% of its total area. But a small partially attritions surface will cause permanent damage and must be replaced, which cost a lot of money. To solve the above problem, the AIR-JET translational mechanism was designed. It consists of a small stepping motor coordinating the large ball bearing for the direct handing and the hollow shaft rotor. When the motor rotates the ground ball screw will drives the AIR-JET which was fixed on slider for, reciprocating horizontal motion. The movement of AIR-JET push is the silk in motion. However, the quality of the silk way be adversely affected. The Taguchi Method was designed to perform experiments in order to obtained operating parameters. Under the optimal operating parameters, the GR surface utilization ratio reaches above 56%. The relative GR life also could be lengthen to 3.5times. Moreover, because of the revising of AIR-JET material, also improve the damage of pottery. It also significantly cut down service requirement and the maintenance expenditure. It reduces the massive stocks of spare parts and the interruption of maintenance work to the production.

The scale is based on the viewpoints and theories related to the life meaning of Rogers, Erikson, Viktor, Frankl, May and Yalom. The mtain purpose of the research is to set up a“Holistic Meaning of life Scale(HMLS) for junior high school students of Taiwan”,including seven dimensions --life goal, life value, life freedom, self-concept, religion support, death acceptance, ascension and 56 items. The scale is implemented by stratified cluster sampling. The 1102 testees are drawn from northern part, central part, southern part and eastern part of Taiwan. The whole scale internal consistency reliability Cronbach’s α coefficient is 0.801 and the test-retest reliability is 0.966 which is an evidence of stability and consistency. Furthermore, through Canonical Correlation Analysis, it reveals that the similarity 0.69 between the scale and Purpose of life scale set up by Song Qiu-Rong in 1992. In terms of the evaluation of the mode of goodness of fit, the result shows that only the life freedom part needed further adjusting, whereas the rest six dimensions were correspond to the condition. Therefore, this scale reaches the medium level of the mode of goodness of fit. Based on the above-mentioned analysis, the Holistic Meaning of life Scale (HMLS) is a suitable scale for junior high school students of Taiwan with stable reliability and validity.
