Abstract:
abstractThe aim of this paper is to develop a Cognitive Grammar-based analysis of English Copy-raising (CR) constructions such as Richard seems like he is dancing. We argue that the notion of reference-point plays a crucial role in licensing the matrix-subject of the construction. In CR, with the epistemic verbs seem and appear, the matrix-subject functions as a reference-point in relation to the pronominal copy (if a copy exists) in the embedded clause. The aboutness topicality of the matrix-subject in CR is expected, owing to its reference-point property. The epistemic CR construction is acceptable without a pronominal copy if the matrix-subject functions as a reference-point in relation to the complement clause. The same type of analysis is applied to the CR construction with perceptual resemblance (PR) verbs – sound, look, feel, and smell – leading to the conclusion that the strong dichotomy between epistemic and PR verbs is illusory. It is further demonstrated that expletive there-raising in CR is motivated by the same reference-point phenomenon. The difference between there-raising and other CR examples stems from the role of there as a setting subject. Our reference-point-based analysis predicts a metonymic interpretation of the matrix-subject, which we attribute to the connection between reference-point and metonymy.

Abstract:
The extracellular matrix (ECM) is a crucial component of the tumor microenvironment involved in numerous cellular processes that contribute to cancer progression. It is acknowledged that tumor–stromal cell communication is driven by a complex and dynamic network of cytokines, growth factors and proteases. Thus, the ECM works as a reservoir for bioactive molecules that modulate tumor cell behavior. The hepatocyte growth factor (HGF) produced by tumor and stromal cells acts as a multifunctional cytokine and activates the c-MET receptor, which is expressed in different tumor cell types. The HGF/c-MET signaling pathway is associated with several cellular processes, such as proliferation, survival, motility, angiogenesis, invasion and metastasis. Moreover, c-MET activation can be promoted by several ECM components, including proteoglycans and glycoproteins that act as bridging molecules and/or signal co-receptors. In contrast, c-MET activation can be inhibited by proteoglycans, matricellular proteins and/or proteases that bind and sequester HGF away from the cell surface. Therefore, understanding the effects of ECM components on HGF and c-MET may provide opportunities for novel therapeutic strategies. Here, we give a short overview of how certain ECM components regulate the distribution and activation of HGF and c-MET.

Abstract:
Abstract Hepatocyte growth factor (HGF )/scatter factor (SF ) is the ligand for a tyrosine kinase cell surface receptor encoded by the MET protooncogene (c-MET). HGF/SF can induce proliferation and motility in epithelial cells and promotes invasion of carcinoma cells and NIH3T3 fibroblasts transfected with both HGF/SF and c-MET genes. Our results show that HGF/SF and c-MET also play a role in adhesion and invasion of human lymphoma cells. c-MET mRNA is expressed in hemopoietic cells, such as hemopoietic progenitor cells (CD34+ cells) in bone marrow (BM) and mobilized peripheral blood, immature B cells in cord blood and BM, and germinal center B-centroblasts. In normal peripheral blood B cells, which are c-MET−, c-MET expression was induced by PMA, ConA, HGF/SF, and Epstein-Barr virus (EBV) infection. Using immunohistochemistry, we detected c-MET on the cell surface of large activated centroblasts in lymph nodes from patients with B-non–Hodgkin's lymphoma and Hodgkin's disease. In the latter group, c-MET expression correlated well with the presence of EBV. Because HGF/SF and c-MET promote metastasis of carcinoma cells, we studied the effects of c-MET stimulation by HGF/SF of B-lymphoma cells on properties relevant for metastasis, ie, adhesion, migration, and invasion. HGF/SF stimulated adhesion of the c-MET+ B-cell lines to the extracellular matrix molecules fibronectin (FN) and collagen (CN) in a dose dependent manner. However, adhesion to laminin was not affected by HGF/SF. Adhesion to FN was mediated by β1-integrins α4β1 (VLA4) and α5β1 (VLA5) since blocking antibodies against β1- (CD29), α4- (CD49d), or α5- (CD49e) integrin subunits, completely reversed the effect of HGF/SF. Furthermore, HGF/SF induced adhesion was abrogated by addition of genistein, which blocks protein tyrosine kinases, including c-MET. Addition of HGF/SF resulted in a sixfold increase in migration of c-MET B-lymphoma cells through Matrigel, compared to medium alone. In rat fibroblast cultures, HGF/SF doubled the number of c-MET+ B-lymphoma cells that invaded the fibroblast monolayer. In these adhesion, migration and invasion assays HGF/SF had no effect on c-MET− cell lines. In conclusion, c-MET is expressed or can be induced on immature, activated, and certain malignant B cells. HGF/SF increased adhesion of c-MET+ B-lymphoma cells to FN and CN, mediated via β1-integrins α4β1 and α5β1 , and furthermore promoted migration and invasion.

Abstract:
Bakery product is a product with huge business opportunities in the domestic and international halal food market. Bakery companies are demanded to keep the trust of the consumers to the bakery product. The design of the halal assessment model is required to determine the critical point in the bakery-making business process. This assessment tool is intended to understand, know, and determine the critical point of the bakery production process from the halalness degree and is reviewed from all aspects such as the materials’ content, as well as the material acquisition and processing method based on 18 criteria of GMP principles (Good Manufacturing Practices). The halal assessment model designed in this research used QFD (Quality Function Deployment) approach which was integrated into the company’s business process and the halal critical bakery was grouped based on SCOR (Supply Chain Operations Reference) model. Matrix 1 integrated GMP (Good Manufacturing Practices) and business process (BP), matrix 2 integrated GMP (Good Manufacturing Practices), and halal critical bakery (HCB). The results of the design model implementation based on the standards set by the Halal Auditor of LPPOM MUI found that the standard matrix component 1 was met by the company by 47%, while the matrix component 2 was only able to meet the Auditor standards by 34% and the matrix component 3 standards were able to fulfilled by the company by 75%. The fulfillment value of each matrix is influenced by the negative gap that occurs, the negative gap occurs because of the standard criteria in the technical matrix that are not met. The result of this halal assessment model design is expected to help the company in evaluating and controlling critical points found in the business processes.

Abstract:
Abstract Metastases cause 90% of human cancer deaths. The metastatic cascade involves 5 steps: local invasion, intravasation, extravasation, metastatic site colonization, and proliferation. While individual mediators of these processes have been investigated, interactions between these mediators remain less well defined. We previously identified a structural complex between receptor tyrosine kinase c-Met and β1 integrin in metastases that form under certain biological and therapeutic inducers, including bevacizumab. Using novel cell culture and in vivo assays, we found that c-Met/β1 complex induction promotes breast cancer intravasation and adhesion to the vessel wall but does not increase extravasation. These effects may be driven by the ability of the c-Met/β1 complex to increase mesenchymal and stem cell characteristics in breast cancer cells. Multiplex transcriptomic analysis revealed upregulated Wnt and hedgehog pathways after c-Met/β1 complex induction in breast cancer cells. We subsequently used CRISPR to introduce a β1 integrin point mutation that prevented binding to c-Met and led to reduced intravasation, confirming the importance of c-Met/β1 integrin binding for the metastatic cascade. OS2966, a therapeutic B1 integrin blocking antibody, disrupted c-Met/β1 binding as well, and decreased invasion, mesenchymal gene expression, and mesenchymal morphology of breast cancer cells. Bone-seeking breast cancer cells exhibited higher c-Met/β1 complex levels than parental controls and preferentially adhere to tissue-specific matrix. Patient bone metastases demonstrated higher c-Met/β1 complex levels than brain metastases. Thus, our research suggests the c-Met/β1 complex drives breast cancer cell intravasation and preferential affinity for bone tissue-specific matrix. Pharmacological targeting of the complex may prevent metastases, particularly osseous metastases.

Abstract:
Tumor progression requires a crosstalk with the tumor surrounding, where the tumor matrix plays an essential role. We recently reported that only the matrix delivered by a CD44v6-competent (ASMLwt), but not that of a CD44v6-deficient (ASML-CD44vkd) rat pancreatic adenocarcinoma line supports metastasis formation. We here describe that this matrix provides an important feedback toward the tumor cell and that CD44v6 accounts for orchestrating signals received from the matrix. ASMLwt cells contain more hyaluronan synthase-3 and secrete higher amounts of >50 kDa HA than ASML-CD44vkd cells, which secrete more hyaluronidase. Only the ASMLwt-matrix supports migration and apoptosis resistance, which both can be initiated via CD44v6, c-Met, and α6β4 ligand binding and proceed via FAK, PI3K/Akt, and MAPK activation, respectively. However, c-Met- and α6β4-initiated signaling are strongly augmented by the association with CD44v6 as only very weak effects are observed in CD44v6-deficient cells. The same CD44v6-dependent convergence of motility- and apoptosis resistance-related signals also accounts for human tumor lines. Thus, CD44v6 promotes motility and apoptosis resistance via its involvement in assembling a matrix that, in turn, triggers activation of signaling cascades, which proceeds, independent of the initiating receptor-ligand interaction, in a concerted action via CD44v6.

Abstract:
Matrix adhesion via integrins is required for cell survival. Adhesion of epithelial cells to laminin via integrin α3β1 was previously shown to activate at least two independent survival pathways. First, integrin α3β1 is required for autophagy-induced cell survival after growth factor deprivation. Second, integrin α3β1 independently activates two receptor tyrosine kinases, EGFR and Met, in the absence of ligands. EGFR signaling to Erk promotes survival independently of autophagy. To determine how Met promotes cell survival, we inhibited Met kinase activity or blocked its expression with RNA interference. Loss of Met expression, but not inhibition of Met kinase activity, induced apoptosis by reducing integrin α3β1 levels, activating anoikis, and blocking autophagy. Met was specifically required for the assembly of autophagosomes downstream of LC3II processing. Reexpression of wild-type Met, kinase-dead Met, or integrin α3 was sufficient to rescue death upon removal of endogenous Met. Integrin α3β1 coprecipitated and colocalized with Met in cells. The extracellular and transmembrane domain of Met was required to fully rescue cell death and restore integrin α3 expression. Thus Met promotes survival of laminin-adherent cells by maintaining integrin α3β1 via a kinase-independent mechanism.

Abstract:
Författarna har haft ett samarbete med Panduro Hobby i samband med deras årliga miljökampanj. Syftet med examensarbetet har varit att med hjälp av befintliga produktutvecklingsprocesser och livscykelanalyser (LCA) ta fram en hållbar textil produkt med växtfärgning. Tanken var att konsumenter sedan själva skall kunna ta fram och växtfärga denna hållbara textilprodukt. Miljömedvetenhet och hållbarhet inom textilindustrin är ett aktuellt ämne. Trots det saknar dagens konsumenter förståelse för textilindustrins påverkan på miljön och har bristande kunskap om textila material för att kunna göra miljövänliga val ute i handeln. Både konsumenter och företag uttrycker att de gärna vill bidra till en mer miljövänlig textilindustri men att de saknar kännedom, resurser och verktyg för att göra det. Därför valde författarna av examensarbetet att undersöka hur en hållbar textil produkt kan tas fram med hjälp av livscykelanalyser, produktutvecklingsmetoden Product Ideas Tree (PIT) samt växtfärgning. Alla steg under produktutvecklingsprocessen valdes ur miljöhänsyn och efter de förutsättningar som krävs för att göra en så miljövänlig textil produkt som möjligt. Resultatet av undersökningen blev en växtfärgad tygkasse i 100 % lin. Efter framtagningen av produkten gjordes en livscykelanalys benämnd MET-matris för att analysera produktens miljöpåfrestning. Matrisen konstaterade att produkten inte har avsevärda miljöbrister. Med examensarbetet och den framtagna produkten vill författarna uppmuntra konsumenter och företag till att fortsätta visa engagemang och intresse för förändringar som gynnar miljön med förhoppningen om att få fler att agera mer hållbart.
The authors have had a collaboration with Panduro Hobby in addition to their annual environmental sustainability campaign. The aim of the thesis has been to develop a sustainable textile product with natural dye using existing product development processes and Life Cycle Assessment (LCA). The idea was that consumers later on would be able to produce this sustainable textile product and dye it themselves. Environmental awareness and sustainability in the textile industry is a topical subject. Nevertheless many consumers lack sufficient knowledge of textile materials to make environmentally friendly choices in the commerce. Both consumers and businesses express that they would like to contribute to a more environmentally friendly textile industry, but that they lack the knowledge, resources and tools to do it. Therefore, the authors of the thesis chose to explore how a sustainable textile product may be produced with the help of Life Cycle Assessment and the product development method Product Ideas Tree (PIT). All steps in the product development process were carefully chosen with consideration to the environment and the circumstances required to make the textile product as sustainable as possible. The study resulted in the development of a canvas bag made out of 100% linen dyed it with natural dye. After the product development a Life Cycle Analysis, referred to as MET Matrix, was done to analyse the product's environmental strain. The matrix noted that the product does not have significant environmental burdens. With the thesis and the produced product the authors would like to encourage consumers and businesses to continue to show commitment and interest in changes that benefit the environment, with the hope of getting more people to act more sustainably.

Abstract:
Células-tronco adultas podem ser isoladas de vários tecidos, dentre eles a polpa dentária humana, tecido originado na papila dentária do dente em desenvolvimento. Estas linhagens multipotentes podem ser estudadas sob vários aspectos, como na elucidação da histogênese de tumores. O objetivo deste estudo foi inferir a histogênese do mixoma odontogênico, neoplasia odontogênica benigna, analisando a expressão de proteínas da matriz extracelular (MEC) e de metaloproteinases da matriz (MMPs) em células-tronco adultas de polpa dentária humana. Três linhagens diferentes de células-tronco originadas de polpas dentárias humanas IDPSCs (DL-1, DL-2 e DL4) foram utilizadas. As proteínas analisadas foram as mesmas expressas na neoplasia: vimentina, colágeno tipo I, fibronectina, tenascina, ácido hialurônico e MMPs (MMP-1, MMP-2 e MMP-9). Imunofluorescência e ensaios enzimáticos foram utilizados para analisar a presença de proteínas nas células cultivadas e no meio de cultura condicionado por estas células, respectivamente. Todas as linhagens celulares expressaram a vimentina e nenhuma expressou o ácido hialurônico. A linhagem celular DL-1 expressou todas as outras proteínas da matriz extracelular estudadas, enquanto que na linhagem DL-2 apenas não foi observada a expressão do colágeno tipo I. Fibronectina e tenascina não foram observados na linhagem DL-4. Todas as linhagens expressaram todas as MMPs, sendo que a produção de MMP-2 nas três linhagens foi significantemente maior que a de todas outras MMPs. Baseado nas condições deste estudo, é possível concluir que a expressão de proteínas da MEC e de MMPs em células-tronco de polpa dentária humana apresentaram perfil similar àquela apresentada no mixoma odontogênico, exceto pela ausência de marcação do ácido hialurônico em todas as linhagens. A ausência de secreção de ácido hialurônico pelas IDPSCs poderia indicar que o mixoma odontogênico deriva de uma célula mais diferenciada que as células-tronco.
Adult stem cells can be isolated from different tissues including the human dental pulp, a structure originated from the dental papillae. These cell lineages are of importance in a series of studies, as the analysis of tumors histogenesis. The aim of this study was to infer the histogenesis of odontogenic myxoma, a benign odontogenic neoplasia by analyzing the ECM and MMPs molecules expressed in human dental pulp stem cells. Three different lineages of immature dental pulp stem cells (IDPSCs) (DL-1, DL-2 and DL-4) were used. The proteins searched were those expressed by the tumoral cells: vimentin, type I collagen, fibronectin, tenascin and hialuronic acid (HA) and the matrix metalloproteinases (MMP-1, MMP-2 and MMP-9). Immunofluorecence and enzymatic assays were used for analyzing the presence of the proteins in the cells and in the culture media conditioned by the cells, respectively. All the lineages expressed vimentin; however none expressed HA. DL-1 lineage expressed all the other ECM proteins, and the expression of type I collagen was not observed in the DL-2 lineage. Fibronectin and tenascin were not observed in the DL-4 lineage. All the lineages expressed all the MMPs. The release of MMP-2 from all cell lineages was significantly higher than those of all other MMPs. Based on the conditions of this study its possible to conclude that the overall expression of MEC proteins and MMPs in the lineages of human dental pulp stem cells were similar to those found in the odontogenic myxoma, except for the absence of hyaluronic acid. The absence of HA secretion by the IDPSCs could indicate that the odontogenic myxoma tumoural cells derive from a cell more differentiated than the stem cells.

Abstract:
Ce travail a porté sur la caractérisation et la quantification en 3D de la répartition de charges de différents types (nanoparticules, nanotubes, etc.) dans des matrices polymères. Nous nous focalisons sur les techniques de tomographie en microscopie électronique. Une approche multiple en tomographie électronique a été réalisée : la tomographie en FIB/MEB (faisceau d’ions focalisé/microscope électronique à balayage), la tomographie en MEB et la tomographie en MET (microscope électronique en transmission). Les nanocomposites polymère sont généralement élaborés aux fins d’améliorer les propriétés physiques (mécanique, électrique, etc.) du matériau polymère constituant la matrice, grâce à une addition contrôlée de charges nanométriques. La caractérisation de tels matériaux, et l’établissement de corrélations précises entre la microstructure et les propriétés d’usage, requièrent une approche tri-dimensionnelle. En raison de la taille nanométrique des charges, la microscopie électronique est incontournable. Deux systèmes de nanocomposite polymère ont été étudiés par une approche multiple de tomographie électronique : P(BuA-stat-S)/MWNTs (copolymère statistique poly (styrène-co-acrylate de butyl) renforcé par des nanotubes de carbone multi-parois), et P(BuA-stat-MMA)/SiO2 (copolymère statistique poly(butyl acrylate-co-methyl methacrylate) renforcé par des nanoparticules de silice). Par combinaison de divers techniques, la caractérisation et la quantification des nanocharges ont été possibles. En particulier, la taille, la fraction volumique et la distribution des charges ont été mesurées. Cette étude a ainsi fourni des informations en 3D qui contribuent à mieux comprendre les propriétés des nanocomposites. Une attention particulière a été portée aux artefacts et causes d’erreur possibles durant l’étape de traitement 3D. Nous avons également essayé de comparer les différentes techniques utilisées du point de vue de leurs avantages et inconvénients respectifs, en dégageant des possibilités d’amélioration future
This work is focused on the characterization and quantification of the 3D distribution of different types of fillers (nanoparticles, nanotubes, etc.) in polymer matrices. We have essentially used tomography techniques in electron microscopy. Multiple approaches to electron tomography were performed: FIB-SEM (focused ion beam/scanning electron microscope) tomography, SEM tomography and TEM (transmission electron microscope) tomography. Polymer nanocomposites are basically synthesized in order to improve the physical properties (mechanical, electric, etc.) of the pure polymer constituting the matrix, by a controlled addition of fillers at the nanoscale. The characterization of such materials and the establishment of accurate correlations between the microstructure and the modified properties require a three-dimensional approach. According to the nanometric size of the fillers, electron microscopy techniques are needed. Two systems of polymer nanocomposites have been studied by multiple electron tomography approaches: P(BuA-stat-S)/MWNTs (statistical copolymer poly(styrene-co-butyl acrylate) reinforced by multi-walled carbon nanotubes) and P(BuA-stat-MMA)/SiO2 (statistical copolymer poly(butyl acrylate-co-methyl methacrylate) reinforced by silica nanoparticles). By combining various techniques, the characterization and the quantification of nanofillers were possible. In particular, statistics about size, distribution and volume fraction of the fillers were measured. This study has then provided 3D information, which contributes to a better understanding of properties of the nanocomposites. Attention has been paid to analyze carefully original data, and artifacts and causes of errors or inaccuracy were considered in the 3D treatments. We also attempted to compare benefits and drawbacks of all techniques employed in this study, and perspectives for future improvements have been proposed

African matrix refers to every ancestral cultural heritage, territorial, monumental, linguistic and organizational, both in documents and urban vestiges as in orality, transmitted by black Africans enslaved and preserved in the territory by memory through manifestations, reinventions and reterritorialisations in Campinas in the form of groups, Marches, processions, cultural manifestations, peoples and traditional communities. All manifestations have as a fundamental representation for their existence and practice the commitment to the transmission of knowledge, safeguard and preservation of this African ancestry, including the permanent struggle against racism, discrimination and diverse intolerances. This thesis developed a new look at the spaces and territories of the Campinas' African matrix, focusing on the contributions of groups, points of culture, movements and cultural manifestations, traditional ?terreiro? communities (Umbanda, Candombl? etc) and the contemporary formation and reterritorialisations of these places. For this, it investigated the historical construction, post-abolition of slavery and the apparent "invisibility" of the African matrix in the city; The strategies of official erasure of this memory and cultural vestiges; And analyzed the process of reconstitution of records and spatial and cultural vestiges, with the 1998 Constitution as the basis for the elaboration of public policies related to this matrix.It said that African cultural heritage in its knowledge, values and practices increases its visibility through the struggle of the black movement, cultural groups and traditional peoples and communities. Valuing the wealth of this contribution implied in the obligation and the contradiction of recognizing the place of subalternization and stereotypy conferred on black people in Brazilian society and the commitment to the territorial transformation of this reality.It was important to realize that spatial inequality is incorporated into social inequality by merging, in urban space, the interests of capital, state action and the struggle of broad segments of the population as a form of resistance against segregation and the right to the city. This thesis recovered several actions of people and groups linked to the African matrix that contributed, and still do, to the construction of Campinas, even when in its daily life this city seems to move away from them; Campinas, when planned, organized and constructed, faced the choices of its leaders and the actions of the movements so that the population in its totality was inserted.It was when this work was inserted reworking the understanding of this identity of African matrix, from the perception of the possibilities of self representation in the urban space by the local cultures.
Matriz africana ? toda heran?a ancestral cultural, territorial, monumental, lin-gu?stica e organizacional, tanto em documentos e vest?gios urbanos quanto na orali-dade, transmitidos pelos negros africanos escravizados e preservados no territ?rio pela mem?ria atrav?s de manifesta??es, reinven??es e reterritorializa??es em Campinas em forma de grupos, marchas, cortejos, manifesta??es culturais, povos e comunidades tradicionais. Todas as manifesta??es t?m como representa??o fundamental para sua exist?ncia e pr?tica o compromisso com a transmiss?o de saberes, salvaguarda e preserva??o dessa ancestralidade africana, incluindo a luta permanente contra o racismo, discrimina??o e intoler?ncias diversas. Essa tese desenvolveu um novo olhar sobre os espa?os e territ?rios de matriz africana de Campinas, focando nas contribui??es dos grupos, pontos de cultura, movimentos e manifesta??es culturais, comunidades tradicionais de terreiro (Umbanda, Candombl? etc) e na forma??o e reterritorializa??o contempor?nea desses lugares. Para tanto, investigou a constru??o hist?rica, p?s-aboli??o da escravid?o e a aparente ?invisibilidade? da matriz africana na cidade; as estrat?gias de apagamento oficial dessa mem?ria e dos vest?gios culturais; e analisou o processo de reconstitui??o dos registros e vest?gios espaciais e culturais, tendo a Constitui??o de 1998 como base para a elabora??o de pol?ticas p?blicas referentes a essa matriz. Avaliou que a heran?a cultural de matriz africana em seus saberes, valores e pr?ticas amplia sua visibilidade por meio da luta do movimento negro, dos grupos culturais e dos povos e comunidades tradicionais. Valorizar a riqueza desta contribui??o implicou na obriga??o e na contradi??o de reconhecer o lugar de subalterniza??o e estereotipia conferidos aos negros e negras na sociedade brasileira e o compromisso com a transforma??o territorial desta realidade. Foi relevante perceber que a desigualdade espacial se incorpora ? desigualdade social ao se fundirem, no espa?o urbano, os interesses do capital, a a??o do Estado e a luta de amplos segmentos da popula??o como forma de resist?ncia contra a segrega??o e pelo direito ? cidade. A tese recuperou v?rias a??es de pessoas e coletivos ligados ? matriz africana que contribu?ram, e ainda contribuem, para a constru??o de Campinas, mesmo quando em seu cotidiano essa cidade parece rumar para longe delas; Campinas, ao ser planejada, organizada e constru?da, enfrentou as escolhas de seus dirigentes e a atua??o dos movimentos para que a popula??o em sua totalidade fosse inserida. Foi a? que este trabalho se inseriu ao reelaborar a compreens?o dessa identidade de matriz africana a partir da percep??o das possibilidades de auto representa??o no espa?o urbano pelas culturas locais.

The contemporary conjuncture based on the capitalistic knowledge converges to the corporal consciousness that makes us see, feel, taste and hear, be in/to pieces. Disembodied reason legitimate and legislate ways of being and living socially and its development is the dehumanization of human relations causing pain and suffering. The objective of this work is to discuss the body as pedagogical matrix through imagistic/artistic elements: music, painting and literature. Metaphors lead to self knowledge of human subjectivity and approach us to the kaleidoscope of sensitive knowledge and enables learning to learn with the infinite combinations of images, knowledge, feelings and worldviews. The song Mem?ria da Pele comes in the voice of Maria Bet?nia speak of the memories that are not mine, but are tattooed in me in the memory of skin, singing the memories of a love lived by who tries to forget rationally, but the body insists on remembering. It is password to think about what we are. The short story by Clarice Lispector, entitled Miss Algarve, narrates the life story of an unmarried and virgin woman, and her encounter with an alien called Ixtlan. Until then, she who lived as if every day were a Monday, found herself seduced by the pleasure of having a body in contact with another body, which also allowed her to give visibility to the bodies of others. She had repudiation by the immorality that her body and the other s perspired. The discovery of the body brings important lessons for nursing, involving our body and the others'. The painting the flying bed or Henry Ford Hospital, by Frida Kahlo, is our final metaphor. The traumatic experience of abortion is shown in this painting trough the picture of the artist naked in a hospital bed. This painting invites us to reflect on our work process. We need to think in multiple dimensions of the being and accept the invitation of art, so that the lightness confronts us with the weight imposed by the hegemonic ideology. I believe it is not a single view, but the many views that should justify the knowledge and practices of nursing; what matters is that they are woven into the dialogue, democracy, provided that protagonism of those individuals involved in this process, in the wandering and uncertainty, in the rewiring, solidarity, plurality. To this end, the body must be the great pedagogue that is able to be viewed not as a tapestry seen by the right view, as the logical knowledge sees, but seen by the opposite side in its singular, irregular, discontinuous weavings
A conjuntura contempor?nea alicer?ada no saber capital?stico conflui para a inconsci?ncia corporal que nos faz ver, sentir, saborear, ouvir, ser em/aos peda?os. A raz?o descorporificada legitima e legisla modos de ser e de viver socialmente e tem como desdobramento a desumaniza??o das rela??es humanas, causando dor e sofrimento. O objetivo deste trabalho ? discutir o corpo como matriz pedag?gica mediante elementos imag?sticos/art?sticos: m?sica, pintura e literatura. As met?foras levam a um auto conhecimento da subjetividade humana e nos aproxima do caleidosc?pio do saber sens?vel e possibilitam aprender a aprender com as infinitas combina??es de imagens, conhecimentos, sentimentos e vis?es de mundo. A m?sica Mem?ria da Pele vem na voz de Maria Bet?nia falar das lembran?as que n?o s?o minhas, mas est?o em mim tatuadas na mem?ria da pele, cantando as recorda??es de um amor vivido de quem tenta esquecer racionalmente, mas que o corpo teima em lembrar. ? uma senha para pensar no que somos. O conto de Clarice Lispector, intitulado Miss Algrave, narra a hist?ria de vida de uma mulher solteira e virgem, e seu encontro com um extraterrestre chamado Ixtlan. At? ent?o, ela que vivia como se todos os dias fossem uma segunda-feira, se viu seduzida pelo prazer em ter um corpo em contato com outro corpo, o que lhe permitiu tamb?m dar visibilidade aos corpos dos outros. Tinha rep?dio pela imoralidade que os corpos dos outros e o seu transpiravam. A descoberta do corpo traz li??es importantes para a enfermagem, envolvendo o nosso e os outros corpos. A tela cama voadora ou o Hospital Henry Ford, de Frida Kahlo, ? nossa ?ltima met?fora. A experi?ncia traum?tica do aborto ? mostrada nessa tela atrav?s da pintura da artista nua em cima de uma cama de hospital. Essa tela nos convida a refletir sobre nosso processo de trabalho. Precisamos pensar na multidimensionalidade do ser e aceitar o convite da arte, para que a leveza nos confronte com o peso imposto pelo ide?rio hegem?nico. Acredito n?o ser uma ?nica vis?o, mas as muitas vis?es que devam fundamentar os saberes e fazeres da enfermagem; o que importa ? que sejam eles tecidos no di?logo, na democracia, na condi??o de protagonismo dos sujeitos envolvidos nesse processo, na err?ncia e incerteza, na religa??o, na solidariedade, na pluralidade. Para tanto, o corpo deve ser o grande pedagogo capaz de ser olhado n?o como uma tape?aria vista pelo direito, como v? o saber l?gico, mas vista pelo avesso em suas tramas singulares, irregulares, descont?nuas

Abstract:
Cartilage explant studies have shown that mechanical stimuli increase extracellular matrix (ECM) expression and synthesis in vitro [1]. The use of hydrostatic pressure (HP), as a loading regimen, is of particular interest as it causes no cellular deformation. This may be useful in tissue engineering studies where scaffolds with limited mechanical integrity need to withstand intermittent loading conditions. Studies investigating the effect of HP on 3-D cultures of chondrocytes have met with modest success [2, 3]; however literature on meniscal fibrochondrocytes is lacking.

Abstract:
This paper presents an analysis of a planar tensegrity-based mechanism. In this study, a moving body is joined to ground by four compliant leg connectors. Each leg connector is comprised of a spring in series with an adjustable length piston. Two problems are solved in this paper. In the first, the values of the four spring constants and free lengths are given and the lengths of the four pistons are determined such that: (1) the top body is positioned and oriented at a desired pose; (2) the top body is at equilibrium while a specified external wrench is applied; and (3) the total potential energy stored in the four springs equals some desired value. In the second problem, the values for the four spring free lengths are given and the values for the four spring constants and the lengths of the four pistons are determined such that conditions (1) and (2) from above are met and also the instantaneous stiffness matrix of the top body equals a specified set of matrix values. The paper formulates the solutions of these two problems. Numerical examples are presented.

Abstract:
Air transportation has been being expanded remarkably, and its growth is expected to continue in the coming decades. Environmental issues and airlines require gas turbine manufacturers to produce environmentally friendly gas-turbine engines with lower emissions and improved specific fuel consumption. These requirements can be met by incorporating heat exchangers into gas turbines for intercooling and recuperation. Relevant research in such areas as the design of a heat exchanger matrix, materials selection, and manufacturing technology and optimization has been carried out by a variety of researchers. These works are reviewed in this paper. The recent advance in technologies appears to herald the development of intercoolers and recuperators for civil aeroplane gas turbines. Based on results reported in previous studies, potential heat exchanger designs for an aero gas turbine recuperator, intercooler, and cooling-air cooler are suggested.

Full text
Abstract:
Compressive sensing (CS) theory states that, if certain conditions are met, a signal can be retrieved at a sampling rate that is lower than what Nyquist theorem requires. Among these conditions are the sparsity of the signal and the incoherence of the sensing matrix, which is constructed based on how the sensing system is designed. One effective method to render the sensing matrix incoherent is to use random processes in its construction. Diverse approaches have been proposed to randomize the sensing matrix including transmission at random transmitter positions and spectral coding with the use of a physical structure that responds very differently at disparate frequencies. In this work, a holey cavity with various frequency modes is used to spectrally code the ultrasound wave fields. Then, with the use of CS theory and simulations, it is shown that the sensing system that is equipped with such a cavity performs meaningfully better than a regular system in terms of sensing capacity, beam focusing, and imaging. What is more, the validity of Born approximation is investigated in this work to show its extent of applicability in imaging relatively small targets. Due to computational limitations, the simulation domain has been selected to be comparatively small; yet, the achieved results evidently show the concept and warrant further studies on holey cavities in ultrasound imaging, including their fabrication and experimental corroboration. The decrease in the number of measurements necessary for correct image reconstruction can make ultrasound sensing systems more efficient in size and scan time in a variety of applications including medical diagnosis, non-destructive testing, and monitoring.

Abstract:
Integrally formed ceramic matrix composite structures are being developed for a range of hot-structure applications involving active cooling. In this paper, some advantages of integral textile approaches are summarised and design possibilities for turbine engine combustors are suggested. Advantages of integral textile structures include: 1) joints between ceramic and other materials in hot zones can be avoided; 2) thin skins (< 1 mm) can be formed that are strong and tough, enabling tolerance of higher heat fluxes; 3) compliant structures can be designed, which can limit the development of thermal mismatch stresses; and 4) fabrication costs can be lowered by reducing part counts and steps in processing. This paper discusses some of the non-traditional design and fabrication challenges that must be met to exploit integral textile ceramic structures and offers a preliminary assessment of their viability for handling the thermomechanical loads of an advanced combustor.

Full text
Abstract:
Due to the increased thermodynamical efficiency of a constant-volume combustion compared to a constant-pressure mode, the former one represents an attractive alternative for future gas turbines. The shockless explosion combustion is a method to create a detonation without pressure peaks due to a simultaneous autoignition of the fuel. This method leads to high requirements regarding the filling process. Considering disturbances in the detonation tube these requirements can only be met using closed-loop control. In this paper two adaptive control algorithms are tested on a non-reactive surrogate set-up. One of these control schemes is a novel formulation of a discrete extremum seeking controller. By estimating the first derivative and Hessian matrix of the system, this controller is able to use steps of the Newton method to converge to the optimal control trajectory. This controller is compared to an iterative learning controller using a black-box model with a Hammerstein compensation.

Full text
Abstract:
To investigate the solidification efficiency of sulfoaluminate cement (SAC) and to provide more information for formula optimization, SAC blending zeolite, accelerator and Dura fiber was used as matrix materials for solidification of simulated radioactive borate liquid waste. The simulated radioactive borate liquid waste was prepared with boric acid and sodium hydroxide using drinking water. The performances of solidified waste forms were evaluated mainly basing on matrix compressive strength and leachability. The 28d compressive strength of the solidified waste forms were tested according to Chinese National Standard GB 14569.1-1993, and experiments on water/freezing/irradiation/impact resistance were also carried out. Nuclides Sr, Cs and Co were substituted by their non-radioactive isotopes respectively in leachability test, and the testing procedures were consistent with Chinese National Standard GB 7023-1986. Experimental results showed that it was feasible to solidify borated liquid wastes with SAC. The 28d compressive strength was 13.9MPa, nearly twice of the standard in GB 14569.1-1993. Strength losses in water/freezing/irradiation/impact resistance tests met the demands of GB 14569.1-1993 well. In the leaching test, the 42d leaching rates were 3.39×10−5 cm/d, 4.45×10−5 cm/d and 4.07×10−7 cm/d for Sr2+, Cs+ and Co2+ respectively, much lower than GB 14569.1-1993 limits. Results of leaching test also showed that the leaching mechanism of Co2+ was different from that of Sr2+ and Cs+.

Abstract:
Ceramic matrix composites (CMCs), in particular oxide-based systems, are of interest for use in combustion turbines. While uncoated oxide CMCs have significant hurdles to implementation in gas turbines, the Siemens hybrid oxide CMC system is able to overcome these challenges. These hybrid oxide CMCs provide distinct advantages over the current non-oxide based systems. The benefits of hybrid oxide-based systems for advanced gas turbines will be discussed. Material system developments will be discussed including those completed by a Siemens Power Generation led team in a recent NIST (National Institute of Standards and Technology) sponsored program to prove the concept of advanced hybrid oxide-oxide CMCs for gas turbine engines. The program fabricated a full scale outer combustor liner that was installed in a Solar Centaur 50S engine at a commercial end user site. In November 2006, this hybrid oxide CMC outer combustor liner met the target life goal of 25,000 hrs with 25,404 hrs of field test experience. The final hurdle for design of hybrid oxide CMC components is the ability to accurately analytically predict behavior. Methods and approaches to address this challenge are discussed as well.

Abstract:
This paper presents the objectives, design procedure and results of a senior design project during the spring semester of 2009. A team of five mechanical engineering senior students were challenged to design a pressurized connector spool for the original equipment manufacturer’s Integrated Compression System (ICS). This system is comprised of two modules: a separator/compressor and a high-speed, direct drive electric motor. In this concept, the motor and separator/compressor each are mounted on two magnetic bearings and their shafts are connected together using a flexible coupling. Because the flexible coupling has to be installed after both of the individual shafts are inserted into their casings (from opposite ends), the connector spool accessibility is a main concern. The students developed eight initial concepts that were compared using a concept screening matrix. The top two scored ideas were selected for further review. One dimensional simplified calculations were performed to roughly size these concepts. The final design chosen was then further developed using solid modeling and finite element stress analysis. The proposed design met the requirements for mechanical integrity, ease of manufacturability and improved accessibility.

Abstract:
BNFL has produced and operates a wide range of DrumScan® gamma measurement systems for monitoring packages, drums and boxed wastes arising from nuclear power plant reprocessing, fuel fabrication and decommissioning operations. The challenges associated with decommissioning operations are met by employing a range of technologies predominantly High Resolution and Low Resolution spectrometry (HRGS & LRGS). This paper describes how BNFL Instruments’ LRGS and HRGS DrumScan® gamma measurement systems have been used for the assay of uranium resides and potentially contaminated low level wastes by Capenhurst Integrated Decommissioning Project (IDP) in the UK. A description of the two Capenhurst segmented HRGS systems is included. Whilst Segmented Gamma Scanning is a well established technique for the non-destructive assay of gamma emitting radioisotopes in drummed waste, these systems utlise unique features to address the specific measurement requirements. The first system is configured for the accurate measurement of both small sized containers of uranium residues arising from recovery operations and low level wastes potentially contaminated with uranium contained in 200 litre drums. To achieve a high level of accuracy, this system uses a novel mechanical arrangement to overcome the wide variety of container sizes, and the unique “TransWeight” and “Transmission” matrix correction techniques which provide significant improvements over conventional Segmented Gamma Scanner matrix correction techniques. The second system is configured for Nuclear Safety purposes to provide an upper limit of the 235U present in 200 litre drums of potentially contaminated waste prior to the opening of the drums for sorting and uranium recovery operations. This system is configured to report an appropriately pessimistic upper estimate of the 235U present. A brief description of the LRGS systems used by Capenhurst is also provided. These systems have served to quantify the 235U content within a variety of potentially contaminated waste items ranging from 200 litre drums to 1m3 boxed waste.

Abstract:
The goal of development assistance is to deliver measurable results. At the Inter-American Development Bank (IDB), the Development Effectiveness Framework (DEF) was adopted to enhance the likelihood this goal is met. The key objective of this analysis is to enhance our understanding of the role the set of tools and processes adopted at the IDB, from project design to completion, play in the assessment of a projects success and effectiveness. Specifically, we are interested in teasing out the role different dimensions of project design, assessed through the Development Effectiveness Matrix (DEM), and execution performance indicators, as per the Project Monitoring Report (PMR), have on the delivery of effective and successful projects measured through the Project Completion Report (PCR) methodology implemented at the IDB. We also explore the validation process of PCRs and delve into the effectiveness analysis at the level of specific objectives and result indicators, identifying key pitfalls associated with objectives not being met. Overall, our findings provide strong validation for the DEF and its tools. We find robust evidence for the importance of the quality at entry assessment conducted through the DEM. In particular, the quality of the results matrix at approval is a strong determinant of project success and effectiveness at closure, and the quality of the Evaluation Plan is strongly associated with the effectiveness of a project. In terms of execution performance, our analysis finds that, on average, projects that execute a lower share of their approved loan amount, are put on Alert, or are classified as a Problem, in its first three years of execution; and projects that experience a higher share of their outputs discontinued, with respect to their first results matrix, are most likely to be ineffective in achieving their objectives and will likely be rated as unsuccessful.

Abstract:
As of 2004 and continuously to this day, the annual growth rate of renewable sources has been greater than that of all fossil fuels combined. In the midst of this transition to cleaner energy, natural gas is the only fossil fuel that has increased its share in the global energy matrix. Technological changes in the LNG supply chain, as well as transformations in the global natural gas market, largely explain this growth. This publication provides evidence on the fundamental role that natural gas plays in the energy transition, given that: (i) its greenhouse gas emissions are substantially lower than those of oil and coal; (ii) it provides the firm power necessary to complement intermittent renewable energies; (iii) it is particularly safe compared to other fossil fuels. In line with these attributes, the International Energy Agency projects that the share of natural gas in the global energy matrix by 2040 will remain stable (around 24%), even in its Sustainable Development Scenario, which would allow to meet the goals established in the Paris Agreement.

Abstract:
This master thesis explores the challenges for waste management business models in the field of textiles regarding the requirements of the circular economy, as well as improvement potentials in the current framework conditions. It is concerned with the research question: "Is it advisable to change the frame-work conditions at meso or macro level, with regard to business models for waste management companies in the textile sector that are oriented towards the requirements of the circular economy, and - if so - in what way?” The approach of the study is based on the delta analysis of the e Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the normative requirements with the actual state of the textile and waste management framework conditions and attempts to identify the gaps (the delta). Based on the delta, it develops approaches that are intended to help reduce the gaps. The thesis develops three business models for the target year 2025 in different areas: an exchange platform for sorters, recyclers and designers, an automatic sorting plant and a plant for fibre-to-fibre recycling of mixed materials. It is becoming clear that these business models cannot meet the target requirements for the circular economy. The analysis identifies the remaining gaps in the framework conditions as the main problem. For example, insufficient innovation impulses and the lack of competitiveness of secondary raw materials inhibit the actors from applying and using new technologies and business models. Restricted access to knowledge and information, as well as a lack of transparency between the actors, also prove to be problematic. In order to answer the research question, the study recommends altering the framework conditions at meso and macro level. It proposes a platform for cooperation between designers, the introduction of a material declaration system and an eco-design guideline for textiles as possible development options. In addition, this work offers a matrix of criteria to help the actors test and improve their new waste management business models regarding their suitability for the circular economy. The analysis is carried out from an outsider's perspective on the entire textile industry. It therefore cannot cover and deal with all aspects and individual circumstances of each player in detail. The necessary changes in the framework conditions that have been identified can therefore be used as a basis for further investigations.
