Abstract:
In Christoph Wetzel's 1988 painting, An Everyday Story, the divided canvas proudly depicts women's accomplishments in the German Democratic Republic (Figure 1). On one side, a woman operates a large piece of heavy machinery in a rolling mill, cool and competent behind the enormous mass of metal and gears. On the other side, the same woman helps her two children prepare for school in the morning. In the act of combing her daughter's hair, she looks out directly at the viewer, her expression asking: “And what are you surprised at?” This painting, displayed as part of a 1995 exposition on art commissioned by government agencies in the GDR, graphically displays that government's ideological commitment to women's paid labor, especially in jobs that, in capitalist societies, are often thought to be inappropriate for women.

Abstract:
In casting temperature Laquan silica sol crust process suitable for the production of surface roughness is small, precision high accuracy in size, and has become the mainstream technology has been widely used. Silicon sol casting with high dimensional accuracy, good surface quality and other advantages, is a widely used less advanced technology without cutting, using silica sol casting method can save a lot of machine equipment and processing time, but also greatly saves metal materials. Hard fiber sisal has high tensile strength, resistance to seawater immersion, friction resistance, flexibility and other characteristics, can be used for fishing, sailing, mining, transportation rope, canvas, waterproof cloth and other raw materials. The most commonly used binder in investment casting is silica gel solution (abbreviated as silica sol), such as ethyl silicate hydrolysate, water glass and silica sol.

Abstract:
Cultural Heritage is a crucial socioeconomic resource; yet, recurring degradation processes endanger its preservation. Serendipitous approaches in restoration practice need to be replaced by systematically addressing conservation issues through the development of advanced materials for the preservation of the artifacts. In the last few decades, materials and colloid science have provided valid solutions to counteract degradation, and we report here the main highlights in the formulation and application of materials and methodologies for the cleaning, protection and consolidation of works of art. Several types of artifacts are addressed, from murals to canvas paintings, metal objects, and paper artworks, comprising both classic and modern/contemporary art. Systems, such as nanoparticles, gels, nanostructured cleaning fluids, composites, and other functional materials, are reviewed. Future perspectives are also commented, outlining open issues and trends in this challenging and exciting field.

Abstract:
During the construction of bridges, special attention is paid to geometric parameters, one of the most important parameters of the rideable bed is the evenness of the bases and coatings. Geodetic works provide an integrated approach to solving the problem of controlling the flatness of the base layers, which includes: geodetic survey of the rideable canvas, verification of working documentation, control of the copying string, geometric control of the evenness of the laid asphalt concrete floor slab for the steel concrete span and bridge deck for a metal span structure. Various options for controlling the height position of a copier string and a laid asphalt concrete pavement (using trigonometric and geometric leveling) were reviewed and tested. A priori assessment of the accuracy of the measurement results for each of the methods for monitoring algebraic difference of elevations (amplitudes) was previously performed. The article proposes a combined approach to geodetic control at all stages of work on checking the evenness of the asphalt concrete pavement.

Abstract:
Fadi Yazigi’s exhibition Untitled creatively examines the effects of historical and political instabilities in his homeland over the last decade. Yazigi’s audience stands in the centre of an array of crafted exhibits that range from medium- to large-size everlasting bronze sculptures and brittle clay reliefs to figurative paintings decorating the surfaces of friable rice-paper canvas and fragile daily baked bread. The exhibition’s title is metaphorical: it embodies the ambiguities, inequalities and uncertainties in the daily lives of ordinary people in war-struck Syria. The ‘everyday use’ materiality of Yazigi’s craft assumes a form that reflects the complexities, contradictions and negotiations in the ‘trope of the everyday’ in the region and on a global scale. Yazigi’s work centres on people and human emotions with a nostalgic feeling towards the beings he meets. Yazigi smears oil, ink and acrylics as he employs techniques of drawing, painting, sculpting and moulding, using earth-sourced materials like paper, bread, soil and metal presenting the lives of ordinary people and their humane emotions.

Abstract:
AbstractCultural heritage objects and structures are subjected to a range of weathering processes that result in their decay and destruction. To slow weathering rates and/or mitigate their effects, several protective and consolidant materials have been used during conservation interventions. Treatments based on organic polymers and alkoxysilanes, as well as some traditional inorganic treatments such as lime water, are in many cases either incompatible and/or show limited efficacy. In recent years nanolimes, that is, dispersions of Ca(OH)2nanoparticles in alcohol (as well as alcohol dispersions of other alkaline-earth metal hydroxide nanoparticles), have emerged as an effective and compatible conservation material. Here we review recent advances in the synthesis and application of nanolimes in the field of heritage conservation. First, we present an overview of lime-based conservation materials, with an emphasis on the earliest reports on the use of nanolimes. Subsequently, we present the different methods used to synthesize nanolimes. Afterwards, we describe their carbonation and its consolidation effects. Practical application of nanolimes in heritage conservation are summarized, including consolidation of stone, ceramics, lime mortars and mural painting, as well as deacidification of paper, canvas, and wood. The advantages and limitations of this novel nanotechnology for cultural heritage conservation are outlined. Finally, some conclusions and areas for future research are presented.

Abstract:
The main task of diploma is creating a sacral object and community centre of Salesians in Brno-Líšeň. A construction of the Salesian complex started in 1998. As a result, the whole complex of institution got to the district of Brno-Lisen with the help of the endowment fund for youth. The Congregation focuses on the methods of educating the youth of Don Bosco, the father and teacher of the youth, the first head of the Salesian. The creation of a church is a very desirable step for the Salesian Center, because Masses are currently being celebrated in the existing building in the gym, where not everything is needed to carry out of the event. The church should be developed in the vicinity of Salesian centre and has to be available for a wide range of societies. The architectural project includes the designing of church, parish building and enviroment. The form and view of the complex suit to this environmental area and react on its entire structure. The object consists of two forms, which are connected by the horizontal communication. In the middle of the Salesian complex, there is a semi-open area. The first object is a church with a capacity of approximately 200 hundred visitors, the second object is a parish building, which perform the functions of administration with multifunction space for the exhibitions, aparmtments and offices for its employees.

Abstract:
L'emergence de la notion de framework a marque la programmation par objets ces dernieres annees. Elle formalise sous un nom accrocheur une grande variete de techniques de programmation eprouvees. Dans le vide conceptuel qui a succede au succes du modele classe/instance, les frameworks representent pour beaucoup l'espoir d'un nouveau bond en avant de la technique. En effet l'experience commune aux programmeurs par objets est que le grain de reutilisation n'est plus seulement la classe, mais aussi un systeme de classes reliees par des relations contractuelles un framework. On s'est surtout preoccupe jusqu'ici de la maniere de les construire, voire de les deduire de realisations existantes. Un aspect tres peu etudie est celui de leur utilisation, laquelle est d'autant plus complexe que le framework est plus substantiel. Le present travail propose de faire appel a la technique de meta-modelisation pour arriver a une operationnalisation complete du mode d'emploi d'un framework. Notre contribution a deux aspects: d'une part, la construction d'un systeme de meta-modelisation, appele metagen, au sein duquel nous avons experimente notre proposition, d'autre part, la realisation de trois experiences significatives, permettant, d'une maniere pragmatique, d'evaluer le bien-fonde de notre demarche

O processo de furação é um dos mais utilizados na indústria manufatureira, responsável por cerca de 30% de todas as operações de usinagem. Estima-se que 60% de todas as aplicações de furação na indústria mecânica referem-se a furos curtos, com uma profundidade de até 2,5 vezes o diâmetro da ferramenta. No entanto, um grande número de operações na indústria exige profundidades de furo maiores que 5 vezes o diâmetro. Esse tipo de operação, denominada furação profunda, normalmente requer o emprego de ferramentas e equipamentos especiais. A furação profunda é um processo que possui um grau de complexidade maior do que a furação convencional, devido às condições críticas de usinagem em que se realiza. Tais condições envolvem a dificuldade da formação e do escoamento do cavaco, o comprimento em balanço da ferramenta, a qualidade da superfície e as tolerâncias geométricas e de forma do furo. Este trabalho tem como objetivo principal aprofundar a pesquisa sobre o processo de furação profunda com brocas de canais retos em ferro fundido cinzento GG25, visando um melhor entendimento do processo. Os experimentos foram realizados em linha de produção e em laboratório, utilizando brocas de metal-duro integral com canais retos e com orifícios internos de refrigeração. Como grandeza de saída avaliaram-se a rugosidade, a cilindricidade e a circularidade dos furos, bem como o desgaste de flanco das ferramentas, a força de avanço e o momento torçor gerados. Com os resultados obtidos neste trabalho foi possível adquirir um maior conhecimento sobre o processo de furação profunda em ferro fundido cinzento, que permite melhoras na produção de peças em escala industrial.

Abstract:
Interest for business models and business modeling has increased rapidly since the mid-1990‘s and there are numerous approaches used to create business models. The business model concept has many definitions which can lead to confusion and slower progress in the research and development of business models. A business model ontology (BMO) was created in 2004 where the business model concept was conceptualized based on an analysis of existing literature. A few years later the Business Model Canvas (BMC) was published; a popular business modeling approach providing a high-level, semi-formal approach to create and communicate business models. While this approach is easy to use, the informality and high-level approach can cause ambiguity and it has limited computer-aided support available. In order to propose a solution to address this problem and facilitate the development and communication of Business Model Canvas models, two artifacts are created, demonstrated and evaluated; a structured metamodel for the Business Model Canvas and its implementation in an OMG standards-based modeling tool to provide tool support for BMC modeling.This research is carried out following the design science approach where the artifacts are created to better understand and improve the identified problem. The problem and its background are explicated and the planned artifacts and requirements are outlined. The design and development of the artifacts are detailed and the resulting BMC metamodel is presented as a class diagram in Unified Modeling Language (UML) and implemented to provide tool support for BMC modeling. A demonstration with a business model and an evaluation is performed with expert interviews and informed arguments.The creation of a BMC metamodel exposed some ambiguity in the definition and use of the Business Model Canvas and the importance of graphical presentation and flexibility in the tools used.The evaluation of the resulting artifacts suggests that the artifacts do facilitate the development and communication of the Business Model Canvas models by improving the encapsulation and communication of information in a standardized way and thereby the goals of the research are met.

Abstract:
Objectius Analitzar el patró de riscos psicosocials a la feina i la distribució de les situacions d’ocupació que es defineixen als models demanda-control i demanda-control-suport, dels treballadors assalariats a Espanya entre l’any 2005 i el 2010. Estimar els possibles canvis en les desigualtats en l’exposició als riscos psicosocials l’any 2010, i la diferència amb el 2005, segons els eixos de segregació clàssics del mercat laboral espanyol (gènere, edat i ocupació). Estimar la possible associació entre l’exposició a Exigències psicològiques, Control, Suport social, Inseguretat sobre les condicions laborals, Inseguretat respecte perdre l’ocupació i Inseguretat sobre trobar ocupació i la salut mental de la població assalariada a Espanya l’any 2010 i el canvi respecte el 2005. Mètodes Es comparen dos estudis transversals corresponents a les dues enquestes sobre ”Exposició a factors psicosocials a la feina, precarietat laboral, Doble presència i salut” elaborades per l’Institut sindical del treball, l’ambient i la salut els anys 2005 i 2010. Són dues mostres representatives de la població assalariada a Espanya de 7606 i 5110 treballadors respectivament. Principals resultats L’any 2010 es va produir un augment de l’exposició a alta Doble Presència, alt Ritme de treball i alta Inseguretat sobre trobar una feina; així com una disminució de l’exposició a elevada Inseguretat sobre perdre la feina i Inseguretat sobre les condicions de treball valuoses, i un deteriorament del Suport social de companys i del Suport social de superiors. Es va mantenir l’exposició a baixes Exigències cognitives, baixa Influència i baixes Possibilitats de desenvolupament que s’havia detectat el 2005. Es va produir un augment de la proporció d’exposats a situacions d’alta tensió, vinculat a la intensificació laboral, i a situacions d’exposició a ”iso-tensió”. Tant el 2005 com el 2010 hi havia un gradient per classe ocupacional en l’exposició als riscos psicosocials, de manera que els treballadors manuals eren els més exposats. L’any 2010, hi havia una associació significativa entre l’exposició a altes Exigències, baix Suport social i alta Inseguretat sobre les condicions laborals i la mala salut mental de la població assalariada, tant en homes com en dones, i entre l’exposició a alta Inseguretat sobre perdre l’ocupació i la mala salut mental, en el cas dels homes. Conclusions El deteriorament de l’ambient psicosocial al mercat laboral espanyol que s’ha detectat en aquesta tesi és preocupant des del punt de vista de la Salut pública. Els resultats presentats ressalten la necessitat de millorar l’exposició als riscos psicosocials a la feina a Espanya, per a millorar la salut de la població assalariada i reduir les desigualtats socials en les condicions laborals i, en conseqüència, en la salut.
Aims To analyze the pattern of psychosocial risks at work and of the work situations defined by the models demand-control and demand-control-support, among wage-earners in Spain between 2005 and 2010. To analyze possible changes in exposure inequalities in 2010 compared with 2005 in terms the classic axes of segmentation of the Spanish labor market (gender, age and job category). And to analyze whether there is any association between exposures to Psychological Demands, Control, Social Support, Insecurity over worsening of employment conditions, Insecurity about losing a job and Insecurity about finding a job, and the mental health of the working population in Spain in 2010, and changes with respect to 2005. Methods Two cross-sectional studies corresponding to the Psychosocial Work Environment Survey conducted in 2005 and 2010 in Spain are compared. Both samples are representative of the Spanish working population and the sample sizes are n=7612 and n=5110 respectively. Main results There was an increase in exposure to high Double Presence, low Social Support from colleagues and Social support from supervisors, high Work Pace and high Insecurity about finding a job; and reduction in exposure to high Insecurity about losing a job and to high Insecurity over worsening of employment conditions. There was a stagnation in Influence, Possibilities for Development and Cognitive Demands. A gender- and occupation-related gradient was maintained. There was an increase of situations of exposure to high strain, linked to an intensification of work, and of situations of exposure to ”iso-strain”, with respect to 2005. An occupation-related gradient was maintained, so manual workers are the more exposed. In 2010, there was a significant association between exposure to high Demands, low Social Support and high Insecurity over working conditions, and poor mental health of the working population, both men and women, and between exposure to high Insecurity over losing a job and poor mental health in the case of men. Conclusions The deterioration of the psychosocial environment in the Spanish labor market presented in this article is worrying from a public health point of view. These results highlight the need to improve the exposure to psychosocial risks at work in Spain, in order to improve the health of the working population and reduce social inequalities in job conditions and, in consequence, in health.

A furação, com o uso de brocas helicoidais ou de canais retos, é uma das maiores operações em tempo efetivo de corte na usinagem de um bloco de motor, possuindo assim grande influência sobre os custos de ferramentas de corte deste produto. Estes custos têm o seu valor dobrado se considerada a aplicação do ferro fundido vermicular como material alternativo ao ferro fundido cinzento na construção de blocos de motor. Isto ocorre porque o ferro fundido vermicular possui menor usinabilidade do que o ferro fundido cinzento, o que reduz a vida da ferramenta de usinagem em até 60%, no caso da furação. Este trabalho objetiva estudar a furação de ferro fundido vermicular com brocas de canal reto em metal-duro, revestidas por TiAlN de única camada e de várias camadas de espessuras nanométricas, e por TiN em uma das fases da pesquisa. Porém, conforme já previsto e relatado na literatura, este revestimento apresentou a pior resistência aos mecanismos de desgaste em relação aos revestimentos TiAlN, sendo descartada a análise do seu comportamento na continuidade das pesquisas. Este estudo focou o comportamento das brocas com canais retos, revestidas, em relação ao seu desgaste, erros de forma dos furos obtidos (circularidade e retilineidade), rugosidades produzidas, forças de avanço e momentos torçores. Foram realizadas análises por EDS de elementos químicos presentes em regiões distintas da ferramenta, em busca do entendimento do comportamento dos revestimentos ante os mecanismos de desgaste presentes. Para isto, foram escolhidas as velocidades de corte de 80 e 150 m/min sob avanço único. Esta pesquisa serviu como base para especificações de revestimentos adequados para brocas na furação de blocos em vermicular, através dos quais se obteve redução de custos de 25% aproximadamente neste tipo de processo. Drilling using helical or straight flute drills is one of the largest cylinder block machining operations in terms of cutting real time, pushing strongly the product unity cutting tools costs. The usage of CGI as material alternative for gray iron may double the costs due to its better mechanical properties, which may raise the rate power to weight under increased combustion pressure as ancillary to attend the demand emissions laws. In other words CGI owns poor machinability when compared to gray iron, which reduces the machining tool life up to 60% at drilling side. This research aimed the study of CGI drilling using carbide straight flutes drills, being one group of them coated by one layer and the other one with several nanometric layers thick of TiAlN. Also TiN coated drills belonged to the same batch were tested in the beginning of this study, but as per envisioned their performance did not achieve the TiAlN level, so that TiN coated drills were not considered at this research afterwards. This study focused the behavior of coated straight flute drills in terms of wear, holes form error regarding roundness and straightness, roughness, cutting forces, torsion moment and the understanding of coating behaviors against the wearing mechanisms through EDS analysis of chemical elements present on drills different areas. For this, the cutting speeds of 80 and 150 m/min were chosen under one feed rate. This research was also the basis for afterwards drills coating specification at drilling of cylinder blocks in CGI resulting in machining costs reduction of around 25% at this kind of process.

Abstract:
Els efectes del canvi climàtic incideixen directament en les poblacions de microorganismes fotòtrofs dels tapissos microbians, produint alteracions en altres paràmetres ambientals com és l’increment de la temperatura, que pot provocar sequeres i fins i tot la desertització d’aquests ecosistemes, així com altres efectes en l’osmolaritat de les cèl·lules, degut a l’augment de la salinitat. Els microorganismes esmentats són molt abundants en els tapissos microbians, principalment els cianobacteris i les microalgues, que a més de ser els principals estabilitzadors d’aquests ecosistemes, al mateix temps es troben exposats a diferents condicions d’estrès. La majoria dels estudis que es realitzen per valorar l’impacte que tenen sobre els microorganismes condicions ambientals tan variables utilitzen cultius axènics que provenen de microorganismes aïllats de l’ambient natural o bé de col·leccions de cultius; res més lluny de la realitat, ja que en els ambients naturals els microorganismes fotòtrofs estableixen associacions estables amb microorganismes heteròtrofs i, a vegades, amb altres fotòtrofs. A més, hi ha pocs estudis que analitzin, en aquestes condicions i a nivell individual, els efectes dels paràmetres ambientals o de la pol·lució per metalls en aquestes associacions. La manca de metodologies que poden aplicar-se per esbrinar aquests efectes en un microorganisme en concret, quan està associat amb un altre de manera selectiva, in vivo, de manera ràpida i sense l’ús de cap tipus de tinció, és, per tant, un repte a la hora d’analitzar les possibilitats que tenen aquests microorganismes enfront a canvis tan dràstics. En aquest treball, s’ha intentat solucionar aquesta problemàtica mitjançant l’optimització de diferents tècniques que tenen com a base el microscopi làser confocal, considerant la principal característica dels cianobacteris i les microalgues, que és la d’emetre fluorescència natural. La clorofil·la a és el pigment majoritari d’aquests microorganismes i s’ha utilitzat amb anterioritat com a bioindicador, especialment en estudis realitzats en metalls per altres membre del grup. Així mateix, una problemàtica important és esbrinar el paper que juguen aquests microorganismes en la resistència davant canvis sobtats de les condicions naturals o antropogèniques. En aquest sentit, també s’ha accentuat l’interès en les anomenades cèl·lules dorments i en l’estudi de cèl·lules viables i no viables. Per aquest motiu, en aquest treball s’ha posat a punt una nova metodologia que utilitza el microscopi làser confocal i dos làsers específics i que ha permès determinar el percentatge d’aquestes cèl·lules en mostres exposades a diferents condicions d’estrès. Els microscopis electrònics de rastreig i transmissió, ambdós acoblats a un detector d’energia dispersiva de raigs X, juntament amb el microscopi de transmissió de raig X del sincrotró ALBA, s’han aplicat en mostres sotmeses a varis factors d’estrès per avaluar els canvis morfològics en cèl·lules senceres i en seccions ultrafines, així com en estudis de captació de metalls extra- i intracel·lularment. Els objectius del present treball s’han centrat en l’aplicació combinada de totes aquestes metodologies en dos consorcis de microorganismes: Scenedesmus sp. DE2009 i Geitlerinema sp. DE2011. L’efecte de la llum i la salinitat (com a paràmetres ambientals), així com l’impacte del plom, coure i crom (com a contaminants), s’ha estudiat àmpliament en cèl·lules individuals d’ambdós microorganismes. Finalment, aquesta tesi està estructurada en diferents capítols. El Capítol 3 correspon amb els articles publicats (un d’ells en revisió); així doncs, els resultats obtinguts de les investigacions realitzades s’exposen en les Seccions 3.1, 3.2 i 3.3 i es discuteixen globalment en el Capítol 4.
Los efectos del cambio climático inciden directamente en las poblaciones de microorganismos fototróficos de los tapices microbianos, produciendo alteraciones en otros parámetros ambientales como es el incremento de la temperatura, que puede provocar sequías y hasta la desertización de estos ecosistemas, así como otros efectos en la osmolaridad de las células, debido al aumento de la salinidad. Dichos microorganismos son muy abundantes en los tapices microbianos, principalmente las cianobacterias y las microalgas, que además de ser los principales estabilizadores de estos ecosistemas, a veces se encuentran expuestos a diferentes condiciones de estrés. La mayoría de los estudios, que se realizan para valorar los efectos que tienen sobre los microorganismos condiciones ambientales tan variables, utilizan cultivos axénicos que provienen de microorganismos aislados del ambiente natural o bien de colecciones de cultivos; nada más lejos de la realidad, ya que en los ambientes naturales los microorganismos fototróficos establecen asociaciones estables con microorganismos heterotróficos y, a veces, con otros fototróficos. Además, hay pocos estudios que analicen, en estas condiciones y a nivel individual, los efectos de los parámetros ambientales o de la contaminación por metales en estas asociaciones. La falta de metodologías que pueden aplicarse para averiguar estos efectos en un microorganismo en concreto, cuando está asociado con otro de manera selectiva, in vivo, de manera rápida y sin el uso de ningún tipo de tinción, es, por tanto, un reto a la hora de analizar las posibilidades que tienen estos microorganismos frente a cambios tan drásticos. En este trabajo, se ha intentado solucionar dicha problemática mediante la optimización de distintas técnicas que tienen como base el microscopio láser confocal, considerando la característica principal de las cianobacterias y las microalgas, que es la de emitir fluorescencia natural. La clorofila a es el pigmento mayoritario de estos microorganismos y se ha utilizado con anterioridad como bioindicador, especialmente en estudios realizados en metales por otros miembros del grupo. Asimismo, una problemática importante es valorar el papel que juegan estos microorganismos en la resistencia ante cambios repentinos de las condiciones naturales o antropogénicas. En este sentido, también se ha incrementado el interés por las denominadas células durmientes y en el estudio de células viables y no viables. Por este motivo, en este trabajo se ha puesto a punto una nueva metodología que utiliza el microscopio láser confocal y dos láseres específicos y que ha permitido determinar el porcentaje de estas células en muestras expuestas a diferentes condiciones de estrés. Los microscopios electrónicos de rastreo y transmisión, ambos acoplados a un detector de energía dispersiva de rayos X, junto con el microscopio de transmisión de rayos X del sincrotrón ALBA, se han aplicado en muestras expuestas a varios factores de estrés para evaluar los cambios morfológicos en células enteras y en secciones ultrafinas, así como para los estudios de captación de metales extra- e intracelularmente. Los objetivos de este trabajo se han centrado en la aplicación combinada de todas estas metodologías en dos consorcios de microorganismos: Scenedesmus sp. DE2009 y Geitlerinema sp. DE2011. El efecto de la luz y la salinidad (como parámetros ambientales), así como el impacto de metales como plomo, cobre y cromo (como contaminantes), se ha estudiado ampliamente en células individuales de ambos microorganismos. Finalmente, esta tesis está estructurada en distintos capítulos. El Capítulo 3 corresponde con los artículos publicados (uno de ellos en revisión); así pues, los resultados obtenidos de las investigaciones realizadas se exponen en las Secciones 3.1, 3.2 y 3.3 y se discuten globalmente en el Capítulo 4.
The effects of climate change directly affect the populations of phototrophic microorganisms in microbial mats, causing alterations in other environmental parameters such as the increase in temperature. This in turn causes drought and sometimes the desertification of these ecosystems, as well as affecting the osmolarity of cells due to the increase in salinity. The microorganisms referred to are highly abundant in microbial mats; principally, they are cyanobacteria and microalgae, which, apart from being the main stabilisers of these ecosystems, are exposed to distinct stress conditions at the same time. Most studies carried out to assess the impact on microorganisms of such variable environmental conditions use axenic cultures that come from microorganisms isolated from the natural environment or else from culture collections. Nothing could be further from reality, since—in natural environments—phototrophic microorganisms establish stable associations with heterotrophic bacteria and, at times, with other phototrophs. In addition, very few studies analyse (in these conditions and at individual level) the effects of environmental parameters or of metal pollution in these associations. The lack of methodologies that can be applied to ascertain these effects in a specific microorganism, when this is selectively associated with another, in vivo, swiftly and without using any type of staining, is therefore a challenge in analysing the possibilities of these microorganisms when facing such drastic changes. In the current work, an attempt has been made to solve this problem by means of the optimisation of distinct techniques, based on confocal laser microscopy and centring on the main characteristic of cyanobacteria and microalgae, which is the emission of natural fluorescence. Chlorophyll a is the majority pigment in these microorganisms and has previously been used as a bioindicator, in studies carried out with metals by other members of the group. Determining the role played by these microorganisms in the resistance to sudden changes in natural or anthropogenic conditions is a further, and important, issue. In addition, in this respect, the interest in dormant cells and in the study of viable and non-viable cells has increased. For this reason, a new methodology has been developed in this work; using a confocal laser microscope and two specific lasers, this has allowed us to ascertain the percentage of these cells in samples exposed to distinct stress conditions. The electronic scanning and transmission microscopes, both coupled to an X-ray dispersive energy detector, jointly with the X-ray transmission microscope from the ALBA synchrotron, have been used in samples prepared to evaluate morphological changes due to stress factors both in complete cells and in ultrafine sections, as well as in studies of extra- and intracellular metal extraction. The objectives of this work centre on the combined application of all these methodologies on two consortia of microorganisms: Scenedesmus sp. DE2009 and Geitlerinema sp. DE2011. The effect of light and salinity (as environmental parameters), in addition to the impact of lead, copper and chromium (as pollutants) was studied extensively in individual cells for both microorganisms. Finally, this thesis is organised into distinct chapters. The Chapter 3 correspond to the articles that have already been published (one of them currently under review); thus, the results obtained from the research carried out are therefore presented in Sections 3.1, 3.2 and 3.3 and are discussed globally in Chapter 4.

O Modificador da Resposta Imune Canova® (CA) é um medicamento homeopático indicado para pacientes com sistema imune deprimido, uma vez que este medicamento parece aumentar a imunidade inata e induzir uma resposta imune contra várias e severas condições patológicas, incluindo as neoplasias. Esse aumento da imunidade inata é devido a sua atuação na proliferação e na diferenciação de células hematopoéticas e na indução a diferenciação mononuclear em células da medula óssea. O composto químico N-Metil N-Nitrosuréia (MNU) é um poderoso agente carcinogênico alquilante capaz de ocasionar mutações pontuais, aberrações cromossômicas ou ainda metilação do DNA, que induzem o desequilíbrio no sistema de defesa da célula e, assim, interrompendo mecanismos relacionados a metabolismo celular. Este composto tem sido amplamente utilizado na indução de tumores de fins experimentais. Objetivo do presente trabalho é avaliar o padrão de resposta celular hematopoiética em primatas da espécie Cebus apella expostos ao carcinógeno N-Metil-N-Nitrosuréia (MNU) e submetidos ao tratamento com o Modificador da Resposta Imune Canova®, através da análise de parâmetros hematológicos, bioquímicos, imunes e do ciclo celular. Foram utilizados 13 (treze) animais adultos, da espécie Cebus apella divididos em cinco grupos principais: o controle (negativo e positivo) e o experimental (composto por três subgrupos). O primeiro grupo experimental recebeu o MNU durante trinta e cinco dias, o segundo recebeu o tratamento com o Canova durante três dias, e o terceiro recebeu o MNU durante 35 dias e ao final desse período recebeu tratamento com o Canova durante três dias. A avaliação da reposta celular imune foi através de imunufenotipagem (CD4, CD8, CD3, T, B, NK) e do hemograma completo, a função hepática e renal através análise bioquímica (ALT, AST, GGT, ureia e creatinina) e a avaliação da cinética do ciclo celular por citometria de fluxo. Na análise dos parâmetros hematológicos os valores de hematócrito, hemácias e hemoglobina dos grupos controle positivo apresentaram-se significativamente menores, quando comparados aos grupos controle negativo, demonstrando um quadro de anemia, já o aumento de células da linhagem branca nesses grupos provavelmente é devido à resposta inflamatória do animal frente ao provável processo neoplásico. O aumento dos leucócitos também foi observado nos grupos experimentais tratados com o CA, fato este explicado pela ação do medicamento, que atua como um modificador da resposta imune. Apesar de já ter sido relatado que CA pode atuar aumentando o número de neutrófilos, no presente estudo não observamos esta ação do medicamento, provavelmente pelo curto período de tempo do tratamento. Os monócitos apresentaram-se diminuído no grupo tratado com o MNU e aumentado nos grupos que receberam CA provavelmente pelo medicamento atuar na ativação de macrófagos via estimulação da de monócitos. Na análise bioquímica, a uréia e a creatinina apresentaram-se alteradas nos grupos que receberam o MNU de forma aguda, estas alterações, bem como as encontradas na análise de enzimas hepáticas, podem ser associadas com os sintomas típicos da intoxicação por drogas carcinogênicas. Na análise da cinética do ciclo celular os animais tratados com CA, houve um aumento significativo de células nas fases G0-G1 bem como a porcentagem de células em estágio de proliferação celular (fases G2-M). Concluímos que CA minimizou a toxicidade do MNU em certos parâmetros hematológicos e bioquímicos, podemos observar a sua habilidade parcialmente modificadora da resposta imune, por aumentar a contagem de leucócitos, porém sem alterar o padrão de marcadores imunológicos. Desta forma CA então é capaz de restaurar alguns componentes do sistema hematopoiético, e pode atuar como adjuvante em tratamentos de quimioterapia.
The Immune response modifier Canova® (CA) is a homeopathic drug indicated for patients with a depressed immune system, once this medicine appears to increase the innate immunity and induce an immune response against multiple and severe pathological conditions, including Neoplasms. This increase of innate immunity is due to its involvement in the proliferation and differentiation of hematopoietic cells and mononuclear differentiation induction in bone marrow cells. The chemical compound N-Methyl-N-Nitrosourea (MNU) is a alkylating agent powerful carcinogenic able to cause mutations, chromosomal aberrations and DNA methylation, that induce the imbalance in the defense system of the cell and thus stop mechanisms related to cellular metabolism. This compound has been widely used in the induction of experimental tumors. The goal of this work is to assess the pattern of hematopoietic cell response in Cebus apella primate species exposed to carcinogenic N-Methyl-N-Nitrosourea (MNU) and subjected to the treatment with the Immune response modifier Canova®, through the analysis of biochemical, haematological, immune and cell cycle. We had used 13 (thirteen) adult animals of the species Cebus apella divided into five main groups: the control (negative and positive) and experimental (composed of three subgroups). The first experimental group received the MNU during thirty-five days, the second received treatment with Canova during three days, and the third received the MNU during 35 days and the end of this period received treatment with Canova during three days. Evaluation of cellular immune response was through immunophenotyping (CD3, CD4, CD8, T, B, NK) and complete blood count, liver and kidney function through biochemical analysis (ALT, AST, GGT, urea and creatinine) and kinetic evaluation of cell cycle by flow cytometry. Analysis of haematological values of hemoglobin, hematocrit and red blood cells of positive control groups performed significantly lower when compared to the negative control groups, demonstrating an anemia, while the increased white lineage cells in these groups is probably due to the animal's inflammatory response to neoplastic process. The increase of leukocytes has also been observed in experimental groups treated with the CA, a fact explained by the action of this drug, which acts as a modifier of immune response. Although it has been reported that CA can act by increasing the number of neutrophils, in this study we did not observe this action of the medicinal product, probably by the short time of treatment. Monocytes were decreased in the group treated with MNU and risen in groups that received CA probably by drug act in the activation of macrophages via stimulation of monocytes. In biochemical analysis, urea and creatinine were changed in the groups that received the MNU acutely, these changes, as well as those found in the analysis of liver enzymes, can be associated with typical symptoms of poisoning by carcinogenic drugs. Analysis of cell cycle kinetics of animals treated with CA, there had been a significant increase in cell G0-G1 as well as the percentage of cells in cellular proliferation stage (stageG2-M). We found that CA had minimized the toxicity of the MNU in certain haematological and biochemical, we had observed their partially skill to modify immune response, as improve white blood cell count, but without changing the pattern of immunological markers. Then CA is able to restore some hematopoietic system components and can act as an adjuvant in chemotherapy treatments.

Abstract:
La depressió s’associa a múltiples alteracions biològiques. En aquesta tesi s’analitza les alteracions que es presenten en els pacients depressius respecte als subjectes controls i els canvis que s’observen durant el tractament amb un inhibidor de la recaptació de la serotonina (ISRS). S’ha proposat que els pacients amb depressió presentarien uns nivells de neurotrofines perifèriques inferiors als subjectes sans el que indicaria una disminució de la neuroplasticitat cerebral que es corregiria amb el tractament antidepressiu. Una altra alteració observada en els pacients depressius és la major activació plaquetària i les alteracions en els paràmetres hemostàtics. Aquestes alteracions podrien explicar la predisposició als esdeveniments cardiovasculars en pacients depressius. Els estudis avaluen els nivells de BDNF en plasma i en plaquetes en pacients amb depressió sense tractament respecte al controls sans i valorar els canvis observat en els nivells de BDNF en les diferents fases (8 i 24 setmanes) del tractament amb escitalopram. També es avaluar la funcions adhesives, cohesives i procoagulants plaquetàries en els pacients amb trastorn depressiu major i en les diferents fases del tractament amb ISRSs i comparat amb subjectes sans. Els resultats dels estudis presentats a la tesi mostren que els pacients amb depressió major abans del tractament presenten nivells de BDNF en plaquetes inferiors i nivells en plasma pobre en plaquetes superiors als controls sans. El tractament amb un ISRS (escitalopram) modifica els nivells de BDNF tendint als paràmetres similars als controls, però a les 8 setmanes de tractament solament s’observa un increment significatiu del BDNF plaquetari, aconseguint-se nivells similars als controls, pel que s’ha suposat que el BDNF plaquetari podria ser un marcador de resposta al tractament en fases inicials. A les 24 setmanes de tractament els nivells de BDNF plaquetari i plasmàtic no mostren diferències respecte als controls. També es va observar una correlació negativa entre les nivells de BDNF plaquetari i plasmàtic. Respecte als paràmetres de l’hemostàsia s’observa que els pacients depressius sense tractament presenten un endofenotip protrombòtic amb un increment significatiu del volum de les plaquetes, un increment dels paràmetres d’activació plaquetària, un increment de la fermesa del coàgul, un increment de l’activitat del factor tissular associat a plaquetes, un increment de la formació fibrina i trombina quan s’exposa a una superfície trombogènica en condicions de flux i un increment de l’agregació de les plaquetes en resposta a àcid araquidònic. El tractament amb ISRS normalitza de forma ràpida i eficaç aquests paràmetres, excepte que s’observa un increment de GPIIbIIIa i no es modifiquen les propietats viscoelàstiques dels trombes formats en condicions de cisalla reduïda. Els resultats observats sobre la coagulació amb el tractament amb ISRS podria explicar el major risc de sagnat en els pacients que reben tractament amb aquest grup d’antidepressius. En la discussió es valoren els resultats respecte a estudis previs, alhora que s’analitza la utilitat actual del BDNF com a marcador biològic de depressió a nivell perifèric, la relació entre el BDNF plaquetari i l’activació plaquetària i la possible relació entre BDNF i malaltia cardiovascular. També s’analitza la relació entre depressió i malaltia cardiovascular i els canvis observats amb el tractament amb ISRSs.
Depression is associated with multiple biological alterations. It has been proposed that patients with depression show lower levels of peripheral neurotrophin than healthy subjects, indicating a decrease in brain neuroplasticity and these levels are corrected with antidepressant treatment. Another alteration observed in depressive patients is increased platelet activation and alterations in the hemostatic parameters. These alterations could explain the predisposition to cardiovascular events in depressive patients. These studies evaluate the levels of BDNF in plasma and platelets in patients with untreated depression compared to healthy controls and assess the changes observed in the levels of BDNF in the different stages of treatment with escitalopram (8 to 24 weeks). Also evaluate adhesive, cohesive and procoagulant platelet functions in patients with major depressive disorder and at different stages of treatment with SSRIs and compared with healthy subjects. The study results show that patients with depression before treatment have lower levels of BDNF in platelets and higher plasma levels compared to healthy controls. Treatment with SSRIs (escitalopram) modifies BDNF levels tending to parameters similar to controls, but at 8 weeks of treatment, platelet BDNF achieving levels similar to controls. So, platelet BDNF could be a marker of response to treatment in early stages. At 24 weeks of treatment the levels of platelet and plasma BDNF showed no differences from controls. Also it has been observed a negative correlation between the levels of platelet and plasma BDNF. Regarding the parameters of hemostasis is observed that untreated depressed patients exhibit a prothrombotic endophenotypes with a significant increase platelet volume, platelet activation parameters, clot firmness, tissue factor activity associated with platelets, an increase in thrombin and fibrin formation when exposed to a thrombogenic surface under flow conditions and increased platelet aggregation in response to arachidonic acid. SSRI treatment normalizes quickly and effectively these parameters, but persist an increase in GPIIbIIIa and alterations in thromboelastometric parameters. The results observed on coagulation treatment with SSRIs could explain the increased risk of bleeding in these patients. In discussing, the results are compared with previous studies. The usefulness of current BDNF in peripheral levels as a biological marker of depression, the relationship between platelet activation and BDNF and the possible relationship between BDNF and cardiovascular disease are discussed. We also analyze the relationship between depression and cardiovascular disease and the changes observed with SSRI treatment.

Abstract:
Packing Insulation Was Mike Patrick’s first job at Midwest Manufacturing. He was one of 300 men, mostly young, hired in January 1959 to help Admiral, a Chicago-based company that owned the Galesburg factory, meet America’s seemingly insatiable postwar appetite for appliances. He had failed an eye test during the nurse’s exam at the factory and had to get glasses before he started. Patrick had suspected he needed glasses because he always had trouble see­ing the chalkboard from the back of the room in high school. But because he was an athlete, he didn’t want to tie glasses around his head during basketball games. New hires got the nastiest, most grueling jobs, and stuffing insulation— which was like prickly cotton candy—into bare metal cabinets was one of them. The cabinets came from the metal-cutting area of the factory known as the “black line,” because the steel, darkened with oil, hadn’t yet been painted. The black line was the birthplace of these early Admiral refrigerators. Flatbed semis unloaded massive rolls of thick steel from Chicago—the plant used 10 rolls a day, 50 million pounds a year—that cutters and folding machines would shape into five sides. Gun welders then joined what would become the back, the two sides, and the top and bottom of the refrigerator. They left the door for later. The fused steel cabinet dangled from an overhead conveyor as it rode to the paint shop to be cleaned of its oily residue and painted. It would continue on the conveyor to a cabinet bank, where the empty cabinets gathered until they were needed on the line. When the scheduler called for them, men would slide the cabinets to the line across a concrete floor, which had been treated with a smooth, protective coating to prevent damage. A young man then spread scalding, gooey tar into the corners and up and down the creases of the bare metal cabinets. He shot the tar out of a pistol-gripped nozzle attached to a long canvas hose that he snaked in and around the metal shell.

Abstract:
Ironmakers in the Middle Atlantic states used canals and railways to reduce costs and expand the scale of production with new techniques based on mineral-coal fuel beginning in the 1820s. Salisbury forge and furnace proprietors, who still had teamsters hauling ore, fuel, and metal along dirt roads with wagons in summer and sleds in winter, knew that improved transportation systems would help them get their products to outside buyers. They were less aware that canals and railroads would eventually force them to confront new techniques adopted by ironmakers outside their district. Entrepreneurs in northwestern Connecticut had become interested in waterways as early as 1760, when they wanted to improve the Housatonic’s channel north to Massachusetts in order to float logs downriver to their sawmills. Although the General Assembly authorized a lottery to raise £300 for the project in 1761, the promoters accomplished nothing. The start of construction on the Erie Canal stimulated interest in building a canal along the Housatonic River that would open new markets for the northwest’s ironmakers. Urged on by John M. Holley and others, the Ousatonic Canal proprietors organized a company in 1822 to build from tidewater to Stockbridge, Massachusetts. However, when canal engineer Benjamin Wright’s survey showed the company would have to build enough locks to raise boats a total of 604 feet as they traversed the canal, the project’s supporters backed out. The promoters of the Sharon Canal project, intended to start in Sharon and go down the Oblong River into New York and thence follow the route later used by the Harlem Railroad, accomplished even less. John M. Holley had experienced railroad travel on his 1831 trip to Harpers Ferry. He and his neighbors realized that a railway up the Housatonic valley would gather traffic from the region’s ironworks and, with a connection to the Western Railroad in Massachusetts, open the first year-round route from New York City to Albany. (The railroad along the Hudson River between New York and Albany did not open until 1851.) Several of the region’s ironmasters, including J. M. Holley’s son A. H. Holley, helped raise funds for the construction of the Housatonic Railroad when the state issued a charter in 1836.

Abstract:
Representations of the pig can be found in a wide variety of visual material worldwide, and throughout time. The term ‘pig’ is used here as a general term to cover all domestic and wild forms of Sus scrofa (where relevant and possible precise distinction between these forms will be specified). The images that exist, vary in terms of the form or shape of the pig, the representation of its characteristic features according to sex (male–boar vs female–sow), form (domestic or wild), age (adult pig or piglet), or physical characteristics (i.e. snout, tusks, tail, trotters, hair and hide coloration, razorback, and bristles). A visual appreciation of different living forms can be found in works such as Burnie (2001) or Buczacki (2002). This chapter is concerned with the creation and use of visual images of the pig. It offers a selection of materials dating in range from the medieval to the early modern period and will cite selected examples to represent continuity or change in the use of images where appropriate. The materials providing representations of the pig include (but are not exclusive to) illuminated manuscripts, prints and posters, engravings and drawings on either parchment or paper, canvas paintings, stained and painted glass, wood carvings, embroidery and textiles, stonework, moulded or cast metal, ceramic wares, and figurines. Exclusive porcine works discussing this iconography include those by Foster (1977), Ryba (1983), Brochier (1988), Bonera (1991), and Lawson (1995). In addition to depictions of pigs, functional and decorative and artistic uses were also found for the inedible body parts of real pigs such as the tusks appearing in visual cultural materials reflecting the precious value of the animal by some people. The main approach of this paper is thematic in order to emphasize how visual representations of the pig have had associations with filth, shame, lust, fantasy, care and consumption, inspiration, and human identity. Many assumptions have been made about the relative importance of the sources of inspiration drawn upon for the creation of particular images or motifs in the surviving media, and the availability of these to their creators (for a discussion on the practice of artistic transmission during the Middle Ages, see Scheller 1995).

Abstract:
Although the tenth anniversary of the crisis pictured Love Canal as a thing of the past, the area still inspired dreams of development in the future. That became clear in September 1988, when Health Commissioner David Axelrod returned to Niagara Falls to announce that the state would back Love Canal resettlement. The longtime mayor of Niagara Falls, Michael O’Loughlin, beamed at the news. This was the first “positive statement about Love Canal” in years, he said. Axelrod’s resettlement recommendation was the result of a five-year, $14 million study. Using massive amounts of test data, the study drilled down into Love Canal’s new nature to see if the monumental remediation plan had worked. The study determined that parts of the ten-block Emergency Declaration Area (EDA) had acceptable chemical levels and only slightly higher contamination risks than comparison areas hard by landfills, steel plants, and old manufacturing facilities in the American Rust Belt. While no one could certify the neighborhood’s absolute safety, Axelrod proposed that people might soon move into sections of the nearly empty subdivision. Former residents again fumed at Axelrod. Joann Hale called Axelrod’s decision “piece meal,” at best, and dangerous at worst. Anything but a “black and white” answer about the safety of resettlement was wrong. The ETF’s Roger Cook said that resettlement posed “unacceptable risks” to future residents. Janet Ecker, a former resident not known for screaming and shouting, told a reporter that Axelrod’s announcement was “very sad.” “I don’t agree it is a safe place. The chemicals don’t know that they’re supposed to stop” at certain places. The mere mention of Love Canal brought back unhappy memories to Ecker, who left in 1980 for Florida and was still “glad to be as far away as I can get from that place.” Lois Gibbs went even further: it was morally wrong for the state to resettle the area. As these divergent perspectives on Axelrod’s announcement indicated, Love Canal remained a hotly contested environment well after final evacuation had occurred.

Abstract:
Chapter 4 examines disputes between the abbess of Sainte-Croix, canons of Sainte-Radegonde, and the bishop of Poitiers over jurisdiction and privileges between the eleventh and fourteenth centuries. Poitiers’ spatial, administrative, and mental orientation had shifted to give greater power to the Count and bishop, enhance Sainte-Radegonde’s canons’ status, and place new pressures on the nuns. When the canons resisted the abbess’s claims, she appealed to the papacy to defend their privileges. The pope supported Sainte-Croix’s abbesses’ authority, despite the supposed misogyny of the eleventh- and twelfth-century reform, and encouraged the bishop to intervene on the abbesses’ behalf. Poitiers’ bishop was also a rival to the abbess, however, complicating his response. Chapter 4 demonstrates that the gendering of authority in the high Middle Ages was complicated for both men and women, and that Sainte-Croix’s abbesses constantly sought ways to muster support from allies who were eager to demonstrate power.

In the information era, we are immersed in various kinds of information, giving us the impression that we are well informed. Thousands of pieces of information rush to our perception continuously, either by external (media, colleagues, regulations, rules, norms, directives, law, and practices) or internal canals (apprehensions, affect, mood, emotions). Nevertheless, although some of them are of high informational value, many are useless for in-depth analyses of a given situation because they are not factual. This is why our relationship to the received information is of great importance. Taking distance before sorting out the available information helps us to keep only the elements of high informational value, that is, those that let us see that the situation is made up of multiple factors, likely to be analyzed one by one in terms of their contribution to the identified problem.

Abstract:
The early Spanish adventurers came to America primarily to mine precious metals. Some colonists in eastern North America also had hopes of finding gold and silver, but more turned to the abundant timber and water resources of the New World and undertook lumbering and ironmaking to produce goods for export to the mother country. Through the next 200 years, most American industrial entrepreneurs used energy from wood and from flowing water. Water was a renewable resource, while wood was so abundant that new sources were easily found when a local supply was depleted. The years in which wood had a dominant place in American technology have been described by historian Brooke Hindle as “America’s Wooden Age”; on much of the continent, metal was used only where wood would not serve, as in nails, gun barrels, and cooking pots. Iron was the only metal made in significant quantities in North America during the Wooden Age. Settlers along the American coast reached the roadless interior by ascending the numerous rivers and, until well into the nineteenth century, preferred to move heavy or bulky cargoes by boat or raft. They used the flow and drop of water in streams as their principal source of mechanical power for industry, and only after 1870 did Americans generate more power with steam engines than with waterwheels.” Visitors to Old Sturbridge Village, a living-history museum in Massachusetts that re-creates community life in the early years of the nineteenth century, find wooden buildings, tools made of wood and iron, the smell of wood smoke, and machinery powered by waterwheels. Along the east coast, wood, water in lakes and streams, and iron ore were abundant but had to be used near where they were found until entrepreneurs with access to capital and technological expertise built canals, railways, and, later, electrical power-transmission systems. A craftsman who started a shop with human-powered machinery in town and subsequently wanted to use water power often had to move to a rural site. As more people did this, they spread manufacturing over the landscape or the Northeast.

Abstract:
A new concept of one shot micro-switches is proposed. Different switches have been developed to achieve either ON-OFF switching or OFF-ON switching. They are based on electrothermal mechanisms. ON-OFF switching consists in breaking an electrical connection using energetic material or low melting point metal like aluminum. OFF-ON switching consists in micro-soldering locally two electrical connections. Switches commute with a few hundred of mW and do not need energy to stay in the stable OFF or ON state. These switches are particularly adapted to spatial redundancy applications that need high quality contact and reliable commutation even after long time storage. The fabrication process of these switches is based on classic MEMS technology steps (LPCVD, PECVD, copper electrodeposition, lift-off and plasma etching) and is IC compatible. Fabrication yield reaches 99%.

Abstract:
The design of the femoral components used in hip arthroplasty has evolved from a concept to a standard construct with a few variations. Attempts to remove less bone have become more important as revision surgery many years after primary implantation has become more common. The Mayo Conservative Hip Prosthesis (Zimmer, Inc., Warsaw, IN) was designed to preserve bone and to use broaches that do not require strict superior/inferior access to the femoral canal. The shape of the stem was intended to reduce the amount of subsidence following implantation. The taper in both the anterior-posterior and medial-lateral directions offered an interference fit to ensure rigidity. The VerSys Fiber Metal Taper (FMT) implant (Zimmer, Inc., Warsaw, IN) is a tapered, collarless implant that is coated proximally with fiber metal and has a polished distal tip. It is intended to be inserted without cement and has a successful history of clinical use. Preparation of the canal requires more superior/inferior access for broaching and preparation of the femur.

Abstract:
Joint replacement surgeries are a common treatment for diseased or damaged joints. The procedure typically involves the insertion of a metal stemmed component into the bone canal, either with or without bone cement, to achieve fixation to the host bone. Although this procedure has proven effective, implant loosening remains a relatively common complication, leading to pain and the eventual need for revision surgery.

Abstract:
Plutonium oxide and metal awaiting final disposition are currently stored at the Savannah River Site (SRS) in crimp sealed food pack cans. Surveillances to ensure continued safe storage of the cans include periodic lid deflection measurements using a mechanical device. Trending the lid deflection measurements over time indicates whether tightly sealed cans are pressurizing or depressurizing. Both phenomena may result in reduced can integrity and ultimately in containment failure. Periodic lid deflection measurements have been taken on over 400 cans, and the vast majority indicate no changes in internal pressure. However, several cans were repackaged due to trends in lid deflection which indicated gradual but steady pressure decrease within the container over time. There have been no food can failures since the surveillance program has been instituted. Several cans have been repackaged which would have certainly failed.

Abstract:
For aircraft and rocket engines there is a strong need to measure the pressure in the propulsion system at high temperature (HT) with a high local resolution. Miniaturized sensor elements commercially available show decisive disadvantages. With piezoelectric-based sensors working clearly above 500°C static pressures can not be measured. Optical sensors are very expensive and require complex electronics. SiC sensor prototypes are operated up to 650°C, but require high technological efforts. The present approach is based on resistors placed on top of a 2 mm diameter sapphire membrane (8 mm chip diameter). The strain gauges are made either of antimony doped tin oxide (SnO2:Sb) or platinum (Pt). This material combination allows for matching the thermal coefficients of expansion (TCE) of the materials involved. The morphology of the SnO2:Sb layer can be optimized to reduce surface roughness on the nanometer scale and hence, gas sensitivity. Antimony doping increases conductivity, but decreases the gauge factor. With this nanotechnological knowledge it is possible to adjust the material properties to the needs of our aerospace applications. Tin oxide was shown to be very stable at HT. We also measured a 2.5% change in electrical resistivity at room temperature at maximum membrane deflection. The maximum temperature coefficient of resistivity (TCR) is less than 3.5·10−4 K−1 in the temperature range between 25°C and 640°C. In addition to the device related research work, a novel reusable packaging concept is developed as housing is the main cost driver. After the chip is destroyed the functional device can simply be replaced — housing and contacts can be reused. The MEMS device is electrically contacted with a miniaturized spring mechanism. It is loaded from the harsh environment side into the HT stable metal housing. A cap is screwed into the housing and compresses the inserted seal ring against the chip. The part for electrical contacting on the opposite housing side is not disassembled. The MEMS device is not in direct contact with the housing material, but embedded between two adaptive layers of the same material as the device (sapphire) to decrease thermally induced mechanical stress. Overall weight is 46 g. This packaging concept has been successfully optimized so that the whole assembly can withstand 800°C and simultaneously provides sealing up to 250 bar! After testing in such harsh environment, the small packaging can still be unscrewed to exchange the MEMS device. Due to the reutilization, the packaging can be used far beyond the lifetime of HT MEMS devices.

Abstract:
RFID tags are commonly used to track products in many applications including retail and pharmaceutical industries. Tag readability is detrimental to the successful implementation and use of RFID in commercial applications. Tag readability is adversely affected when tags are adhered to metal surfaces such as metal cans and containers. This paper studies the effect of base material on tag readability. We have designed and built an experimental setup in the RFID lab to perform our studies. Our studies show that the metal effect is influenced by the distance between the tag and the base material (padding material) and the distance between the tag and its RFID reader. The studies also reveal the threshold values for improving tag readability.

Abstract:
It is of interest to exploit the insight from the lateral line system of fish for flow sensing applications. The lateral line consists of arrays of flow sensors, known as neuromasts, with hair cells encased within a gel-like structure called cupula. There are two types of neuromasts, superficial neuromasts, which reside on the surface, and canal neuromasts, which are recessed within a channel with its ends open at the body’s surface. In this work we investigate the modeling of a canal-type artificial lateral line system. The canal is filled with viscous fluid to emulate its biological counterpart. The artificial neuromast consists of an ionic polymer-metal composite (IPMC) sensor embedded within a soft molded cupula structure. The displacement of the cupula structure and the resulting short-circuit current of the IPMC sensor under an oscillatory flow are modeled and solved with finite-element methods. The Poisson-Nernst-Planck (PNP) model is used to describe the fundamental physics within the IPMC, where the bending stimulus due to the cupula displacement is coupled to the PNP model through the cation convective flux term. Comparison of the numerically computed cupula displacement with an analytical approximation is conducted. The effects of material stiffness and and device size on the device sensitivity are further explored.
