Abstract:

Hydrogen transport membranes have gained interest from industry as an alternative to pressure swing adsorption or cryogenic distillation, and are aimed to reduce cost, equipment size, energy consumption and waste generation. Doped strontium cerate stabilized with zirconium exhibit high proton conductivity and chemical stability and is therefore considered to be a promising material for hydrogen transport membranes.The purpose of the work was to investigate if phase pure strontium cerates, stabilized with zirconium and doped with thulium, ytterbium or yttrium, could be synthesized by the Pechini method, and if the membranes exhibited sufficient density. Determination of optimal calcination and sintering parameters was also important parts in the study.SrCe0.75Zr0.20M0.05O3-d, (M=Tm,Y,Yb) were synthesized via the Pechini method, followed by calcination, pressing of green bodies and sintering of dense membranes. Phase purity of powders and sintered membranes was examined by X-ray diffraction. Surface investigation and microstructure was investigated in a scanning electron microscope. Sintering behavior and thermal expansion coefficients was determined by dilatometry. Phase pure and dense orthorhombic perovskite structured SrCe0.75Zr0.20M0.05O3-d;, (M=Tm,Y,Yb) membranes, were obtained by powder calcination at 1000 C, followed by milling and conventional sintering at 1500-1600 C. SrCe0.75Zr0.20Tm0.05O3-d demonstrated the highest density of 98,6%, when sintered at 1500 C. Sintered membranes had a average grain size in the range from 3,2 – 4,9 um. Ball milling is concluded to be of vital importance to obtain sufficient density in the membranes.The membrane characterization is limited to the methods and techniques described above. Hydrogen flux across the membrane, total conductivity, stability in reducing atmosphere and thorough investigation of thermal properties are recommended for further work.

Abstract:

Il metodo agli elementi finiti è stato utilizzato per valutare la distribuzione dei carichi e delle deformazioni in numerose componenti del corpo umano. L'applicazione di questo metodo ha avuto particolare successo nelle articolazioni con geometria semplice e condizioni di carico ben definite, mentre ha avuto un impatto minore sulla conoscenza della biomeccanica delle articolazioni multi-osso come il polso. Lo scopo di questo lavoro è quello di valutare gli aspetti clinici e biomeccanici dell’articolazione distale radio-ulnare, attraverso l’utilizzo di metodi di modellazione e di analisi agli elementi finiti. Sono stati progettati due modelli 3D a partire da immagini CT, in formato DICOM. Le immagini appartenevano ad un paziente con articolazione sana e ad un paziente con articolazione patologica, in particolare si trattava di una dislocazione ulnare traumatica. Le componenti principali dei modelli presi in considerazione sono stati: radio, ulna, cartilagine, legamento interosso, palmare e distale. Per la realizzazione del radio e dell’ulna sono stati utilizzati i metodi di segmentazione “Thresholding” e “RegionGrowing” sulle immagini e grazie ad operatori morfologici, è stato possibile distinguere l’osso corticale dall’osso spongioso. Successivamente è stata creata la cartilagine presente tra le due ossa, attraverso operazioni di tipo booleano. Invece, i legamenti sono stati realizzati prendendo i punti-nodo del radio e dell’ulna e formando le superfici tra di essi. Per ciascuna di queste componenti, sono state assegnate le corrispondenti proprietà dei materiali. Per migliorare la qualità dei modelli, sono state necessarie operazioni di “Smoothing” e “Autoremesh”. In seguito, è stata eseguita un’analisi agli elementi finiti attraverso l’uso di vincoli e forze, così da simulare il comportamento delle articolazioni. In particolare, sono stati simulati lo stress e la deformazione. Infine, grazie ai risultati ottenuti dalle simulazioni, è stato possibile verificare l’eventuale rischio di frattura in differenti punti anatomici del radio e dell’ulna nell’articolazione sana e patologica.

Abstract:

Protein-adsorption occurs immediately following implantation of biomaterials. It is unknown at which extent protein-adsorption impacts the cellular events at bone-implant interface. To investigate this question, we compared the in-vitro outcome of osteoblastic cells grown onto titanium substrates and glass as control, by modulating the exposure to serum-derived proteins. Substrates consisted of 1) polished titanium disks; 2) polished disks nanotextured with H2SO4/H2O2; 3) glass. In the pre-adsorption phase, substrates were treated for 1h with αMEM alone (M-noFBS) or supplemented with 10%-foetal-bovine-serum (M-FBS). MC3T3-osteoblastic-cells were cultured on the pre-treated substrates for 3h and 24h, in M-noFBS and M-FBS. Subsequently, the culture medium was replaced with M-FBS and cultures maintained for 3 and 7days. Cell-number was evaluated by: Alamar-Blue and MTT assay. Mitotic- and osteogenic-activities were evaluated through fluorescence-optical-microscope by immunolabeling for Ki-67 nuclear-protein and Osteopontin. Cellular morphology was evaluated by SEM-imaging. Data were statistically analyzed using ANOVA-test, (p<0.05). At day3 and day7, the presence or absence of serum-derived proteins during the pre-adsorption phase had not significant effect on cell-number. Only the absence of FBS during 24h of culture significantly affected cell-number (p<0.0001). Titanium surfaces performed better than glass, (p<0.01). The growth rate of cells between day3 and 7 was not affected by the initial absence of FBS. Immunolabeling for Ki-67 and Osteopontin showed that the mitotic- and osteogenic- activity were ongoing at 72h. SEM-analysis revealed that the absence of FBS had no major influence on cell-shape. • Physico-chemical interactions without mediation by proteins are sufficient to sustain the initial phase of culture and guide osteogenic-cells toward differentiation. • The challenge is avoiding adsorption of ‘undesirables’ molecules that negatively impact on the cueing cells receive from surface. This may not be a problem in healthy patients, but may have an important role in medically-compromised-individuals in whom the composition of tissue-fluids is altered.

Elliott, Jayne Louise. "Properties and interactions of type III intermediate filaments with CRYAB." Thesis, Durham University, 2013. http://etheses.dur.ac.uk/7017/.

Full text

Abstract:

Glial fibrillary acidic protein is a type three intermediate filament found within astrocytes in the central nervous system and mutations have been found as the cause of Alexander disease, resulting in protein aggregates of Rosenthal fibers with αBcrystallin. Here two glial fibrillary acidic protein mutants of R79C and R239H, located in the LNDR and rod 2A domain respectively, were assembled in vitro and their morphology, assembly competence and interactions with αB-crystallin were assessed. Both mutants were unable to form usual filament lengths but instead were similar to unit length filaments with R239H forming aggregates due to such high protein interactions and the R79C mutant having much lower assembly competent protein interactions. R239H had a much greater affinity for αB-crystallin, likely a reflection that it has one of the most severe phenotypes. An absence of divalent cations equally affected GFAP assembly resulting in compromised compaction and increased filament-filament interactions. The R120G αB-crystallin mutant results in cardiomyopathy and cataract due to aberrant interactions with desmin intermediate filaments, due to an increased oligomer size and therefore these interactions were studied and compared to wild-type interactions. Temperature and pH also alter the oligomer size of αB-crystallin and were therefore investigated with αB-crystallin-type III intermediate filament interactions. It was found that ischemic conditions and increased temperatures promote their association, demonstrated by increased co-pelleting under high speed sedimentations. There was a preference for binding to desmin filaments thus showing how desmin-wild-type αB-crystallin interactions are important for homeostasis in muscle. Passive microrheology was used to complement this and investigate how αB-crystallin may be modulating desmin filaments under equilibrium. From these experiments wild-type αB-crystallin reduced the frequency-dependent passive viscosity η(f) and the G’, whereas the cardiomyopathy- and cataract- causing R120G mutant increased the η(f).

Hui, Kailin. "Metabolism and host specificity in the Rhizobium leguminosarum species complex." Thesis, University of York, 2014. http://etheses.whiterose.ac.uk/7017/.

Abstract:

Forming symbiosis with legumes and fixing nitrogen, rhizobia can be ranked among the most ecologically significant bacteria in the world. Two features of rhizobia viz. metabolism and host specificity are important determinants of their growth and their ability to form symbiosis with plants. Investigations of these two features are common in studies conducted using laboratory based experimental and computer based bioinformatics methods. Rhizobium is the largest genus of root-nodulating bacteria. Hence, abundant data can be collected by investigating members of this group. 72 isolates of root-nodule bacteria were collected from a field adjacent to Wentworth College, University of York from plants of genus Vicia and Trifolium; 36 from each. Their metabolic assays showed diversity. Analysis of genome data revealed the presence of five contiguous genes in isolates from Vicia, as well as in the reference strain Rlv. 3841; but absent in the isolates from Trifolium. Limited information was available on the five genes. Work in this thesis promotes our understanding of R. leguminosarum genotype and phenotype. Cross nodulation assays showed that all biovar viciae strains retained their ability to form symbiosis plants of genera Vicia, Pisum and Lathyrus. Metabolic study and celC phylogeny showed that clusters of different species - type strains of R. pisi and R. fabae, and type strains of R. phaseoli and R. etli were closely related to each other. Studies on distribution of the five biovar-specific genes showed that they were widely distributed in biovar viciae strains with one exception – the type strain of R. fabae did not have any of five bvs genes, which suggested these bvs genes were not essential for nodulating Vicia plants. Single gene mutation of the five genes in Rlv. 3841 and subsequent competition nodulation tests suggested that inactivation of the bvs4 and bvs5 genes could lead to decreased competitiveness in mutants as compared to wild type on Vicia sativa, Vicia faba and Pisum sativum plants. Complementation of bvs5 gene restored competitiveness. Enzyme assays for the two genes confirmed the activities described in their annotation viz. aliphatic nitrilase for bvs4 and sulfite oxidase for bvs5. Mutation of bvs4 results in a loss of bvs5¬-encoded enzyme activity, indicating that these two genes are probably in an operon. In conclusion, the study shows that relations among rhizobial strains and species can be observed by studying bacterial metabolism. The work hints at a novel competitive mechanism that requires further investigation.

Urban designers, planners and social commentators have argued that the contemporary suburban landscape of isolated subdivisions, office parks, and malls is devoid of identity and meaning. Critics protest the environmental impact of suburban development patterns and the increasing fragmentation of communities; yet Americans continue to locate in the suburbs in increasing numbers. Designers have responded to the problems of suburban sprawl with plans for new self-contained towns, while few proposals have been made for retrofitting existing suburbs. This thesis explores the relationship between spatial structure, perception, and behavior in the contemporary suburban landscape from a neighborhood perspective. Twenty-four interviews were conducted with residents of Lexington and Burlington, two suburban towns in eastern Massachusetts. These towns have similar histories and demographic characteristics but distinctly different patterns of development. Lexington has retained a semi-rural, residential character, while Burlington has developed more of its land and encouraged commercial and industrial uses. In each of the two towns, two contrasting neighborhoods were selected for study. Each of these four neighborhoods represents a different type of development, based on its street system, density, lot sizes, access to open space, and proximity to shops and services. In each of the four neighborhoods, six interviews were conducted using questionnaires, maps and photographs. The interview data from these four neighborhoods, combined with an analysis of existing spatial patterns, suggest that five inter-related themes are important in suburban town and neighborhood design. These themes are i) integrated road networks, ii) visible and accessible open spaces, iii) social town centers, iv) walkable neighborhoods, and v) active front yards. Based on these themes, a set of related principles is proposed for interventions to improve the existing suburban environment.

Space radiation poses a significant hazard to astronauts on long-duration missions, and the low fluences of charged particles characteristic of this field suggest that bystander effects, the phenomenon in which a greater number of cells exhibit damage than expected based on the number of cells traversed by radiation, could be significant contributors to overall cell damage. The purpose of this thesis was to investigate bystander effects due to signaling between different cell types cultured within 2D and 3D tissue architectures. 2D bystander signaling was investigated using a transwell insert system in which normal human fibroblasts (A) and keratinocytes (K) were irradiated with 1 GeV/n protons or iron ions at the NASA Space Radiation Laboratory using doses from either 2 Gy (protons) or 1 Gy (iron ions) down to spacerelevant low fluences. Medium-mediated bystander responses were investigated using three cell signaling combinations. Bystander signaling was also investigated in a 3D model by developing tissue constructs consisting of fibroblasts embedded in a collagen matrix with a keratinocyte epidermal layer. Bystander experiments were conducted by splitting each construct in half and exposing half to radiation then placing the other half in direct contact with the irradiated tissue on a transwell insert. Cell damage was evaluated primarily as formation of foci of the DNA repair-related protein 53BP1. In the 2D system, both protons and iron ions yielded a strong dose dependence for the induction of 53BP1 in irradiated cells, while the magnitudes and time courses of bystander responses were dependent on radiation quality. Furthermore, bystander effects were present in all three cell signaling combinations even at the low proton particle fluences used, suggesting the potential importance of including these effects in cancer risk models for low-dose space radiation exposures. Cells cultured in the 3D constructs exhibited a significant reduction in the percentages of both direct and bystander cells positive for 53BP1 foci, although the qualitative kinetics of DNA damage and repair were similar to those observed in 2D. These results provide evidence that the microenvironment significantly influences intercellular signaling and that cells may be more radioresistant in 3D compared to 2D systems.

One of the key impediments to the development of enhanced geothermal systems is a deficiency in the tools available to project planners and developers. Weak tool sets make it difficult to accurately estimate the cost and schedule requirements of a proposed geothermal plant, and thus make it more difficult for those projects to survive an economic decision-making process. This project, part of a larger effort led by the Department of Energy, seeks to develop a suite of decision analysis tools capable of accurately gauging the economic costs and benefits of geothermal projects with uncertain outcomes. In particular. this project seeks to adapt a set of existing tools, the Decision Aids for Tunnelling, to the context of well-drilling, and make them suitable for use as a core software set around which additional software models can be added. We assess the usefulness of the Decision Aids for Tunnelling (DAT) by creating two realistic case studies to serve as proofs of concept. These case studies are then put through analyses designed to reflect project risks to which geothermal wells are vulnerable. We find that the DAT have sufficient flexibility to model geothermal projects accurately and provide cost and schedule distributions on potential outcomes of geothermal projects, and recommend methods of usage appropriate to well drilling scenarios.

Abstract:

L'électro-activation (EA) est une approche novatrice qui permet l'isomérisation du lactose en lactulose directement in situ du lactosérum. Cependant, le lactosérum électro-activé (LAEA) possède un pH hautement alcalin. Alors, l'objectif de ce travail est de contribuer au développement d'un procédé électrolytique pour la neutralisation du LA-EA. La détermination de l'effet des paramètres opératoires et physico-chimiques du milieu électro-activé sur la formation du lactulose a montré qu'un rendement maximum en lactulose de 34,71% est obtenu en utilisant une solution de lactosérum d'une concentration de 7% et 60 min de temps d'électro-activation sous une intensité du courant de 1000 mA après un temps de relaxation de 48 h. Trois configurations électrolytiques ont été étudiées pour la neutralisation de la solution du lactosérum: (1) en neutralisant avec l'anolyte généré dans le compartiment anodique; (2) en inversant les deux électrodes (cathode et anode) et (3) en introduisant le LA-EA dans le compartiment central du réacteur. Les résultats ont montré la faisabilité du processus d'électro-neutralisation. En effet, le pH de la solution a diminué soit en ajoutant des ions H+ (cas des configurations 1 et 2), ou en éliminant les ions OH- de la solution (cas de la configuration 3). De plus, il a été révélé que l'électro-neutralisation est ralentie lorsque (I) augmente pour les deux configurations 1 et 2, tandis que pour la configuration 3, elle est accélérée. Les résultats de l'évaluation de l'effet de ce processus sur les propriétés du LA-EA ont montré que la neutralisation de la solution après un temps de relaxation de 48 h n'a pas affecté la composition glucidique du LA-EA, notamment le lactulose. De plus, elle a permis d'améliorer les propriétés techno-fonctionnelles des poudres résultantes en particulier en termes de reconstitution instantanée.
Electro activation (EA) is a novel approach that allows the isomerization of lactose to lactulose in situ from whey. However, electro-activated whey (LA-EA) has a highly alkaline pH. Therefore, the objective of this work is to contribute to the development of an electrolytic process for the neutralization of LA-EA. The determination of the effect of physico-chemical parameters on the formation of lactulose showed that the maximum lactulose yield (34.71%) is obtained for a feed concentration of 7% at 60 min of electro-activation, under a current intensity of 1000 mA after a relaxation time of 48 h. Three electrolytic configurations were studied for neutralization of the whey solution: (1) neutralizing with the anolyte generated at the anode compartment; (2) reversing the two electrodes (cathode and anode) and (3) introducing LA-EA into the central compartment of the reactor. The results showed the feasibility of the electro-neutralization process. Indeed, the pH of the solution decreased either by adding H+ ions (case of configurations 1 and 2), or by removing OH- ions from the solution (case of configuration 3). Furthermore, it was revealed that electro-neutralization is slowed down when (I) increases for both configurations 1 and 2, while for configuration 3, it is accelerated. The results of the evaluation of the effect of this process on the properties of LA-EA showed that the neutralization of the solution after a relaxation time of 48 h did not affect the carbohydrate composition of LA-EA, especially lactulose. Moreover, it improved the technofunctional properties of the resulting powder in particular in terms of instant reconstitution

Introdução: Complicações pulmonares pós-cirurgia cardíaca podem causar aumento do tempo de ventilação mecânica invasiva (VMI), internação hospitalar prolongada, infecções pulmonares e incremento na mortalidade. Objetivo: Avaliar a associação da pressão expiratória máxima (PEM), pressão inspiratória máxima (PIM) e pico de fluxo expiratório (PFE) mensuradas no préoperatório, com o tempo de VMI no pós-operatório de cirurgia cardíaca. Métodos: Foram incluídos pacientes internados para a realização de cirurgia eletiva de revascularização do miocárdio e/ou troca valvar. O tempo de VMI foi medido até o momento da extubação completa do sujeito. As demais variáveis clinicas e cirúrgicas foram coletadas até o momento da alta hospitalar. Resultados: Cento e vinte e cinco pacientes de ambos os sexos (77 homens), com idade média de 61±11 anos, foram avaliados. Uma medida de PEM mais elevada no pré-operatório associou-se com menor tempo de VMI após ajuste para fatores de confusão. A PIM e o PFE não tiveram associação significativa com o tempo de VMI, após análise através de modelo multivariável. Conclusão: A avaliação da PEM no pré-operatório de cirurgia cardíaca de grande porte é um marcador prognóstico útil e de baixo custo em relação ao tempo de VMI no pós-operatório.

Abstract:

Objetos de Aprendizagem são recursos relevantes para ensejar a aprendizagem em função de seu caráter modular, pois permitem oferecer condições para uma atividade apoiada por recursos alocados por demanda face a necessidades específicas de uma turma ou aluno em particular. Essa característica é um elemento benéfico e facilitador, mas adiciona um aspecto que dificulta seu uso, derivado da dificuldade de localização do objeto de aprendizagem apropriado para necessidades específicas. Em decorrência, existe considerável esforço de investigação de estratégias para facilitar a localização e o acesso a Objetos de Aprendizagem (OA), adequados às necessidades de alunos e professores, pois a dificuldade em realizar esses processos ocasiona uma redução na frequência de utilização e reutilização dos mesmos em atividades pedagógicas. O local usual para armazenamento desses recursos é um Repositório de Objetos de Aprendizagem (ROA). No entanto, o uso dos objetos de aprendizagem ocorre mais frequentemente no contexto de Ambientes Virtuais de Aprendizagem (AVAs). Face a essas constatações, esse trabalho de pesquisa investigou estratégias para integrar um ROA a um AVA e como esta integração pode apoiar o professor e o aluno na construção e adaptação do plano de ensino e aprendizagem. Essa tese apresenta um referencial teórico sobre Repositórios de Objetos de Aprendizagem e Ambientes Virtuais de Aprendizagem e algumas soluções implementadas para integrar esses sistemas. Além disso, propõe um modelo de integração de repositórios a AVAs e descreve sua implementação bem como resultados derivados do uso da solução integradora construída. Os sistemas escolhidos para validar o modelo implementado foram o repositório CESTA2 e o AVA MOODLE. A hipótese principal é a de que a integração dos sistemas permite que os OA possam ser mais facilmente agregados pelo professor ao AVA no planejamento das unidades de aprendizagem de uma disciplina ou curso e permite que esses recursos sejam recomendados pelo professor ao aluno nas diversas situações de aprendizagem previamente delineadas em cada uma das unidades de aprendizagem ou que surgirem sob demanda ao longo do curso. Nesse sentido a solução proposta visa criar condições para que os OAs possam ser pesquisados e utilizados pelos alunos através de ferramentas disponíveis no próprio AVA. Para validar a integração foram realizados estudos de caso com alunos e professores de duas turmas da disciplina de Projeto de Banco de Dados Relacional do Instituto Federal Sul-rio-grandense, Campus Pelotas. Diferentemente de outros estudos realizados sobre o tema e relatados nessa tese, esse trabalho tem como foco a integração dos ambientes, com a finalidade tecnológica de verificar a interoperabilidade existente entre eles e como finalidade pedagógica verificar como essa integração pode auxiliar professores e alunos. A avaliação e validação realizadas através de estudo de caso com professores e alunos evidenciou que o modelo proposto e implementado atende às expectativas e pode apoiar professores e alunos, nas suas atividades pedagógicas e de aprendizagem, respectivamente. Além disso, o trabalho fruto dessa tese aporta contribuições importantes para as instituições de ensino que utilizam o software livre DSpace como repositório institucional e o MOODLE como AVA Institucional, pois demonstra como esses dois sistemas podem ser integrados para permitir aos seus usuários auferir todos os benefícios que essa integração pode oferecer.
Learning Objects are important resources to give opportunity to the learning according to their modular character, this way they may offer conditions to an activity supported by allocated resources by requests to the specific needs of a class or of an individual student. This characteristic is a beneficial and facilitator element, but it adds an aspect which makes its use difficult due to the learning object’s location difficulty appropriated to the specific needs. As a result, there is significant research effort of strategies in order to facilitate the location and the access to the Learning Objects (LO) adequate to the students and teachers’ needs, because the difficulty in order to perform these processes causes a decrease in the frequency of use and reuse from these ones in activities of teaching and learning. The usual place to store these resources is a Learning Objects Repository (LOR). However, the use of learning objects occurs more frequently in the Virtual Learning Environments (VLEs). Due to these findings, this study researched the strategies to integrate a Learning Objects Repository to a Virtual Learning Environment and how this integration may support the teacher and the student at the construction and adaptation of teaching and learning plan. The present thesis shows a theoretical frame about the Learning Objects Repository and Virtual Learning Environments and some solutions taken to integrate these systems. In addition, it proposes a integration model of repositories to VLEs and it describes its implementation as well as the results from the use of the integrating solution built. The systems chosen to validate the deployed model were the repository CESTA2 and the VLE MOODLE. The main hypothesis is that the integration of the systems allows that the Learning Objects may be more easily added by the teacher to the VLE at the learning unit planning to a subject our course and it allows that these resources be advised by the teacher to the student in several learning situations previously outlined in each learning unit or the ones which arises along the course. At this point of view the solution proposed aims to create conditions so that the LOs may be researched and used by the students through available tools at own VLE. In order to validate the integration were done case studies with students and teachers from two classes of Relational Database Project subject from the Instituto Federal Sul-rio-grandense, Pelotas Campus. Differently from other studies done about the topic and described at this thesis, this study focuses on the environment integration with the technological purpose in order to verify the interoperability presented between them and as teaching purpose to verify how this integration may help teachers and students. The assessment and validation performed through case study with teachers and students showed that the proposed and evidenced model meets the expectations and may support teachers and students in their teaching and learning activities, respectively. Furthermore, the study from this thesis brings important contributions to the educational institutions that use the DSpace free software as institutional repository and the MOODLE as Institutional VLE, showing how these two systems may be integrated allowing to their users all the benefits that this integration may offer.

Abstract:

Linear viscoelasticity theory is used to analyze the dynamic stability of composite, viscoelastic flat plates subjected to in-plane, biaxial edge loads. In deriving the associated governing equations, a hereditary constitutive law is assumed. In addition, having in view that composite-type structures exhibit weak rigidity in transverse shear, the associated governing equations account for the transverse shear deformations, as well as the transverse normal stress effect. The integro-differential equations governing the stability are solved for simply-supported boundary conditions by using the Laplace transform technique, thus yielding the characteristic equation of the system. In order to predict the effective time-dependent properties of the orthotropic plate, an elastic behavior is assumed for tile fiber, whereas the matrix is considered as linearly viscoelastic. In order to evaluate the nine independent properties of the orthotropic viscoelastic material in terms of its isotropic constituents, the micromechanical relations developed by Aboudi [24] are considered in conjunction with the correspondence principle for linear viscoelasticity. The stability behavior analyzed here concerns the determination of the critical in-plane normal edge loads yielding asymptotic stability of the plate. The problem is studied as an eigenvalue problem. The general dynamic stability solutions are compared with their quasi-static counterparts. Comparisons of the various solutions obtained in the framework of the Third Order Transverse Shear Deformation Theory (TTSD) are made with its first order counterpart. Several special cases are considered and pertinent numerical results are compared with the very few ones available in the field literature.

Abstract:

La O-manosilación de proteínas es una modificación postraduccional de gran relevancia en eucariotas. El α−distroglicano (α-DG), componente principal del complejo distrofina-glicoproteína en el músculo y células nerviosas, se encuentra altamente O-manosilado. Existe un grupo de distrofias neuromusculares hereditarias cuya base molecular subyacente es un déficit en la glicosilación del α−DG. Son las llamadas distroglicanopatias (DGPs), las cuales ofrecen a los pacientes una corta esperanza de vida y cuyos síntomas se extienden al cerebro, al músculo y a la retina. Estas enfermedades engloban, de mayor a menor gravedad, el síndrome de Walker-Warburg (WWS), la enfermedad de músculo-ojo-cerebro (MEB) y la distrofia muscular congénita de Fukuyama (FCMD), además de las distrofias musculares congénitas moderadas (MDC) y las distrofias musculares de cinturas (LGMD). Se conocen actualmente 18 genes asociados a DGPs, la mayoría de los cuales codifican el DG y enzimas implicadas directa o indirectamente en su O-glicosilación. En esta tesis doctoral se ha tratado de mejorar nuestra comprensión acerca de los genes y proteínas asociados a las DGPs mediante el abordaje de su expresión y función en un tejido frecuentemente afectado en estas enfermedades: la retina. En el capítulo 1 se resumen el estado actual del conocimiento acerca de estas enfermedades, la glicosilación del α−DG, y su papel en la estructura de la retina. Los capítulos siguientes comienzan cada uno con un breve resumen, y se desglosan individualmente en Introducción, Materiales y Métodos, Resultados y Discusión. El capítulo 2, titulado “Expresión de genes y proteínas asociados a distroglicanopatías en la retina de mamíferos” se centra en la detección de la expresión de los genes POMT1, POMT2, POMGNT1, FKTN, FKRP y LARGE, tanto a nivel de ARNm como de proteína en la retina neural de distintas especies de mamíferos utilizando técnicas de RT-PCR y Western blotting, y su perfil de distribución mediante técnicas de inmunohistoquímica. En el capítulo 3, titulado “POMGnT1 y POMGnT2: Dos N-acetilglucosaminil-transferasas de proteínas que actúan sobre un mismo substrato, el α-distroglicano”, se presenta una revisión de la información obtenida a partir de la literatura y bases de datos públicas, así como de análisis bioinformáticos realizados en este trabajo, sobre las proteínas POMGnT1 y POMGnT2. El conjunto de datos obtenido revela la existencia de una elevada homología entre las secuencias de aminoácidos de las proteínas humanas y sus ortólogas en las distintas especies del filo Cordados. Los integrantes de este taxón constituyen, así, un grupo monofilético para ambas proteínas, cada una de las cuales presumiblemente posee un ancestro común separado. En el capítulo 4, titulado “Alteraciones estructurales en la retina de un ratón KO condicional en el gen Pomt1, modelo de distroglicanopatías”, se exponen los resultados de un trabajo multidisciplinar realizado en estrecha colaboración con grupos de la Universidad Autónoma de Madrid y la Universidad de Alcalá. En nuestro grupo se han estudiado los cambios morfológicos y estructurales que tienen lugar en la retina de un ratón modelo de DGPs en el que el gen Pomt1 ha sido “noqueado” de forma condicional en este tejido. Los análisis llevados a cabo revelaron importantes alteraciones en la organización de la retina externa, incluidas las sinapsis establecidas entre los fotorreceptores y sus células postsinápticas, así como una reactividad aumentada de las células gliales en la retina interna. Finalmente, en el último capítulo se presentan a modo de sumario las conclusiones obtenidas del trabajo desarrollado en esta tesis doctoral.

Abstract:

DE LA TESIS
Si un graf G admet un etiquetament super edge magic, aleshores G es diu que és un graf super edge màgic. La tesis està principalment enfocada a l'estudi del conjunt de grafs que admeten etiquetaments super edge magic així com també a desenvolupar relacions entre aquest tipus d'etiquetaments i altres etiquetaments molt estudiats com ara els etiquetaments graciosos i armònics, entre d'altres. De fet, els etiquetaments super edge magic serveixen com nexe d'unió entre diferents tipus d'etiquetaments, i per tant moltes relacions entre etiquetaments poden ser obtingudes d'aquesta forma.
A la tesis també es proposa una nova manera de pensar en la ja famosa conjectura que afirma que tots els arbres admeten un etiquetament super edge magic. Això és, per a cada arbre T trobam un arbre super edge magic T' que conté a T com a subgraf, i l'ordre de T'no és massa gran quan el comparam amb l'ordre de T .
Un problema de naturalesa similar al problema anterior, en el sentit que intentam trobar un graf super edge magic lo més petit possible i que contengui a cert tipus de grafs, i que ha estat completament resolt a la tesis es pot enunciar com segueix.
Problema: Quin és un graf conexe G super edge magic d'ordre més petit que conté al graf complet 
Kn com a subgraf?.
La solució d'aquest problema és prou interessant ja que relaciona els etiquetaments super edge magic amb un concepte clàssic de la teoria aditiva de nombres com són els conjunts de Sidon dèbils, també coneguts com well spread sets.De fet, aquesta no és la única vegada que el concepte de conjunt de Sidon apareix a la tesis. També quan a la tesis es tracta el tema de la deficiència , els conjunts de Sidon són d'una gran utilitat. La deficiencia super edge magic d'un graf és una manera de mesurar quan d'aprop està un graf de ser super edge magic. Tècnicament parlant, la deficiència super edge magic d'un graf 
G es defineix com el mínim número de vèrtexs aillats amb els que hem d'unir
G perque el graf resultant sigui super edge magic. Si d'aquesta manera no aconseguim mai que el graf resultant sigui super edge magic, aleshores deim que la deficiència del graf és infinita. A la tesis, calculam la deficiència super edge magic de moltes families importants de grafs, i a més donam alguns resultats generals, sobre aquest concepte.
Per acabar aquest document, simplement diré que al llarg de la tesis molts d'exemples que completen la tesis, i que fan la seva lectura més agradable i entenible han estat introduits.
OF THESIS
If a graph G admits a super edge magic labeling, then G is called a super edge magic graph. The thesis is mainly devoted to study the set of graphs which admit super edge magic labelings as well as to stablish and study relations with other well known labelings.
For instance, graceful and harmonic labelings, among others, since many relations among labelings can be obtained using super edge magic labelings as the link.
In the thesis we also provide a new approach to the already famous conjecture that claims that every tree is super edge magic. We attack this problem by finding for any given tree T a super edge magic tree T' that contains T as a subgraph, and the order of T'is not too large if we compare it with the order of T .
A similar problem to this one, in the sense of finding small host super edge magic graphs for certain type of graphs, which is completely solved in the thesis, is the following one.
Problem: Find the smallest order of a connected super edge magic graph G that contains the complete graph Kn as a subgraph.
The solution of this problem has particular interest since it relates super edge magic labelings with the additive number theoretical concept of weak Sidon set, also known as well spread set. In fact , this is not the only time that this concept appears in the thesis.
Also when studying the super edge magic deficiency, additive number theory and in particular well spread sets have proven to be very useful. The super edge magic deficiency of graph is a way of measuring how close is graph to be super edge magic.
Properly speaking, the super edge magic deficiency of a graph G is defined to be the minimum number of isolated vertices that we have to union G with, so that the resulting graph is super edge magic. If no matter how many isolated vertices we union G with, the resulting graph is never super edge magic, then the super edge magic deficiency is defined to be infinity. In the thesis, we compute the super edge magic deficiency of may important families of graphs and we also provide some general results, involving this concept.
Finally, and in order to bring this document to its end, I will just mention that many examples that improve the clarity of the thesis and makes it easy to read, can be found along the hole work.

Abstract:

A alma económica de Portugal vive numa visão puramente orçamental. Acções tão simples como gerir e correlacionar dados estão comprometidos, pois o Estado, em questões patrimoniais, e mais concretamente em relação a bens de domínio público, desconhece o que possui. Isso reflecte-se por toda a estrutura estatal e, por indissociabilidade, no Ministério da Defesa Nacional, assim como no Exército. Bens de domínio público são aqueles que fazem parte do conjunto de coisas do Estado que estão ao serviço dos cidadãos. No que toca a inventariação e integração destes bens contabilisticamente, não existem normativos vinculativos dessa inclusão. Este estudo defende que estes bens devem ser integrados. Constatou-se que o Cadastro de Inventariação do Bens do Estado, o Código de Imposto Municipal sobre os Imóveis, o Plano Oficial de Contabilidade Pública, bem como algumas normas de autor abordam este tipo de questões, apesar de cumprirem apenas fins específicos ou serem demasiados subjectivos. Quanto ao Ministério da Defesa Nacional, constatam-se andamentos diferentes. É notória a falta de uma base comum, assim como metodologias análogas. O que cada um está a fazer fá-lo de uma forma isolada e assente em critérios próprios. Este Estudo providencia uma solução em relação aos normativos para o Ministério da Defesa Nacional e, naturalmente, para o Exército, que passa por uma desagregação sectorial do Cadastro de Inventariação dos Bens do Estado neste Ministério. Tal normativo teria que contemplar as excepções e especificidades do Ministério da Defesa Nacional. Em relação à segurança seriam definidas classificações, a fim de crivar a informação pública. No que toca a valores, estes seriam todos públicos. Por fim, e como resultado deste estudo, esse normativo assentaria nos Critérios de Valorimetria de Avaliação Patrimonial Tributável, no Método Intrínseco para Avaliação de Imóvel Urbano, no Método do Custo de Aquisição, no Método do Valor Matricial e no Método tendo por base Valor Homologado.
Abstract Portugal’s economic core is living within a strict budget vision. Simple measures like data correlations are compromised, mainly due to the State’s ignorance in matters of public goods. This condition spreads throughout all the State´s structure, and therefore through the Ministry of Defense to the Army, as well as the Army. Public goods are belongings that can be consumed by everybody in a society. However there are no abiding standards that include these goods in contabilistic movements. This thesis defends such inclusion. It was found that Cadastral Inventory of Public Goods, Municipality Tax Code on the Property, the Public National Chart of Accounts, as well as some of author’s standards approach this kind of questions, even though they’re too specific. As to the Ministry of Defense we see different approaches and lack of common foundations or methods. Each one follows its own criteria. This thesis presents a solution towards contabilistic procedures standardization that can be applied by the State, namely by the Ministry of Defense and therefore by the Army. The solution would be the sectorial disaggregation of the Cadastral Inventory of Public Goods, always contemplating the exceptions and specificities of this Ministry. As for matters of data security, it would be assigned the proper classification to filter the information for public knowledge. However, all information about the State goods should be public. Last but not least and as a result of this thesis, the presented standardization would mainly, be based on the Valuation Criteria of Tax Asset Valuation, Intrinsic Method for Evaluation of Urban Property, Method of Acquisition Cost, Value Matrix Method and Method based on Value Approved.

Abstract:

As a consequence of anthropogenic activities, future projections suggest that the saturation state of surface ocean waters with respect to carbonate minerals will decline during the twenty-first century owing to increasing atmospheric CO2. As a result calcareous organisms could have difficulty calcifying, leading to production of weaker skeletons and their greater vulnerability to erosion, and ultimately leading to dissolution of calcareous sediments. At the same time, sea surface temperature could be significantly higher and the amount of organic matter deposited within the coastal zone could also increase owing to human activities. Increased deposition of organic matter and subsequent remineralization within the sediments of the coastal region could have implications with respect to the carbonate geochemistry of the pore water-sediment system, affecting rates of carbonate dissolution and precipitation. Increasing dissolution of metastable carbonate minerals, such as high magnesian calcite has been suggested as a mechanism to restore changes in saturation state and pH owing to increasing atmospheric CO2, acting as a buffer, and could counteract any negative effects on calcareous organisms and communities. In order to investigate the effects of climate change and anthropogenic activities on the carbonate biogeochemistry of the shallow water ocean environment, a global physical-biogeochemical box model referred to as SOCM (Shallow-water Ocean Carbonate Model) was developed. Numerical simulations demonstrated that biogenic calcification could decrease by 7-44% throughout the 21st century owing to a decrease in carbonate saturation state. Dissolution of metastable carbonate minerals could increase owing to increased deposition and remineralization of organic matter, but will not result in the production of sufficient alkalinity to buffer the carbon chemistry of the surface ocean water. However, a buffer effect was observed within the pore water system. Sensitivity analysis indicated that the extent of dissolution was mainly controlled by remineralization of organic matter rather than reaction kinetics. In the current standard simulation, the metastable equilibrium of the pore water changed from 21 mol% magnesian calcite to 14 mol% magnesian calcite. Future changes in pore water carbonate saturation state could affect the average composition and rates of precipitation of carbonate cements in contemporary shallow-water sediments.

Abstract:

Article 334 of the Constitution of India (1950) stipulates that certain electoral districts in each state should be reserved for minority groups, namely the “Scheduled Caste”(SC) and the Scheduled Tribe”(ST), through the reservation of seats in the states' legislative assemblies. Even though the original article stated that the reservation policy would be in place for just twenty years, it has been amended several times and is still in effect. This dissertation examines the impact of the policy on the education and health outcomes of the SC population. Variations in seat quotas are generated by the timing of elections in different states and the states’ fluctuating SC populations. The first paper on education uses data from 25 Indian States and 3 Union Territories for the years 1990-2011 to form a panel dataset to estimate the impact of the quota system on both enrollment and dropout rates among SC students in all levels of schooling. I use the fixed effect regression to test the mechanisms through which an elected SC legislator could have an influence on the education outcomes for the SC population in the represented state. I then use the resulting variables as my controls to identify the causal relationship using the dynamic panel data model. I find that a SC legislator has the potential to influence the number of schools built, as well as the amount of education and welfare expenditure allocated to the SC population. Moreover, I find that the SC political reservation has a positive and statistically significant impact on the SC enrollment rates and a negative and significant impact on the dropout rates, in all levels of schooling. Likewise, I use the NFHS-3 dataset and the Cox Proportional Hazard Model to estimate the hazard rates (risks of dying) of children under the age of 12 months (IMR) and under the age of 60 months (U5MR) as influenced by different SC quota share quintiles. I find that the 50-60% quota-share quintile has the biggest impact in reducing the IMR and U5MR among the SC children.

Full text

Abstract:

This dissertation takes work on contour by Robert Morris as a point of departure and develops a set of contour reduction algorithms, called "window algorithms." These involve the notion of a hypothetical window or frame of a specific width (i.e. number of events) through which the contour succession in a given melody is experienced temporally (much like the way a landscape is experienced visually through the side window of a moving automobile or train. Certain normative principles relevant to windows of various widths are devised and represented with the help of symbolic logic and flowcharts. Reiterative application of the window algorithms on a melody to "prune" pitches at a series of successive levels, introduces notions of melodic contour hierarchy that are explored in various ways throughout the dissertation. The application of the algorithms is demonstrated on a variety of 20th century musical excerpts reflecting a wide range of melodic archetypes, thereby enabling observation of the behavior of the algorithms in different musical contexts. Phenomenological and cognitive implications of the algorithms are discussed from the perspective of a listener implementing the algorithm on the fly. An analysis focusing on the Hauptstimmen in the first movement of Schoenberg’s Third String Quartet explores how intervallic features of the reduced contours can form the basis for a tonal-formal reading of the movement. The possibility of extending the theory to the duration domain is also introduced; following a preliminary analysis involving instrumental gestures from the opening of Webern’s Variations for Orchestra, and a discussion of analytical, conceptual, and methodological inconsistencies arising from the application of the algorithms on duration contours, an alternative approach that attaches appropriate durations to (reduced) pitch contours is developed, examined, and advocated. The relationships and interactions between the pitch and duration contours in Berio’s Sequenza I are examined in the light of the proposed theory.

Abstract:

Two experiments were conducted to investigate how performance on a primary rock climbing task is affected by the inclusion of a secondary word memory task. In Experiment 1, twelve experienced rock climbers completed a dual traverse climb and word memory task, with participants’ performance analysed relative to their single task performance (climbing alone and word memory alone). Participants’ climbing efficiency and word recall were significantly lower in the dual-task condition. Experiment 2 examined the effects of emotional content on climbing performance. Fifteen experienced rock climbers completed two dual-tasks, in which they were asked to recall negatively valenced or neutral words. Climbing efficiency, climbing distance, and word recall were all significantly lower in the dual-task conditions, relative to the single-task conditions. Climbing efficiency and climbing distance were also significantly lower in the negative word dual-task, relative to the neutral word dual-task. The findings from these two experiments have important human factors implications for occupational settings that require climbing-like operations, including search and rescue and fire-fighting.

The purpose of this edition of the Sonate da chiesa for theorbo and organ from the Intavolatura di tiorba, opera prima (1669) of Giovanni Pittoni is to make available a clear, modern notation of the theorbo part, which appears in the score in Italian lute tablature, and to place the works within their performance context. This edition enables a keyboardist to read the solo theorbo part to help keep the ensemble together and to help create a continuo realization. Under usual circumstances a continuo player can read the part of the soloist and can use it to instruct how to realize the accompaniment. With tablature, however, the keyboardist is at a disadvantage, since most – practically all – do not read tablature. The accompanying text reveals how the works were used and how the continuo is to be realized, and suggests answers to the problems associated with continuo realization for bass instruments in a solo role. This score is not intended to make the music more accessible to the soloist, since theorbists are already skilled at reading tablature. Additionally, recreating the tablature was unnecessary, since the original source (or facsimile) is easily read. In addition, errors have been identified, and possible answers and solutions are provided.

Conclusão: constata-se que a morfologia da sacroilíaca é influenciada pela incidência pélvica, a qual interfere com os outros parâmetros pélvicos e no equilíbrio sagital, levando, assim, à génese da patologia, ou seja, da espondilolistese.
Background: degenerative spondylolisthesis is a common disease which could affect 11,5% of mondial population, but we do not know exactly the reasons of her pathogenesis. Due to the importante incidence, many studies research risk factors and prevalence that could influence the apparition and complication of pathology. Authors now make a relationship between sagital spinopelvic alignment and degenerative spondylolisthesis. As reported in literature, sacroiliac's angles and morfology have a leading role in this pathology. Objectives: our objectif in this study is to evaluate sagital spinopelvic alignment parameters in order to determining their implication in lumbar degenerative spondylolisthesis. Methodology: computerized literature search in the databases PubMed to identify experimental articles. After the selection of the studies, an analysis of methodological quality was made with Critical Appraisal Skills Programme (CASP). Results: in this study we have been evaluating 9 articles with a total of 2445 patients aged 18 to 88, in each cas e, the parameters os sagital spinopelvic alignment has been calculated to be correlated with lumbar degenerative spondylolithesis. Conclusion: it is verified that the sacroiliac's morphology is influenced by the pelvic incidence, which interferes with the other pelvic parameters like the pelvic tilt, which modificate the sagital alignment, taking to the genesis of the spondylolistesis.

A maior contribuição para a dose no conjunto de exposições, da população a fontes de radiação ionizantes produzidas pelo homem, provem de exames médicos de radiodiagnóstico. A frequência de exames radiológicos e a dose de radiação recebida pelos pacientes, em cada exame, tem merecido a atenção dos profissionais de saúde e das entidades de protecção e segurança radiológica. No sentido de determinar as doses associadas aos vários exames e os respectivos procedimentos, foi recentemente emitido pela Agência Internacional da Energia Atómica um código de práticas (TRS 457), útil em laboratórios de dosimetria e em hospitais. Neste contexto, a dosimetria assume uma importância central. A mensuranda é o kerma no ar, e a sua medição é realizada com recurso a instrumentos adequados tais como câmaras de ionização, entre outros, com calibração rastreável a um padrão primário. Em Portugal, o laboratório responsável pelo controlo metrológico de dosímetros é o Laboratório de Metrologia das Radiações Ionizantes (LMRI) do Instituto Tecnológico e Nuclear(ITN). O objectivo principal deste trabalho foi a realização da dosimetria dos feixes das várias qualidades de radiação do radiodiagnóstico, tais como, as RQR e RQA, aplicadas ao diagnóstico convencional, as RQT, aplicadas à tomografia computadorizada, e as qualidades definidas pelo Bureau International dês Poids et Mesures (BIPM), aplicadas à mamografia. Consequentemente foram estabelecidos os procedimentos mais adequados à calibração dos dosímetros utilizados em meio clínico. Foi estudado em particular, o melhor método para a calibração de câmaras de ionização do tipo lápis, dosímetros utilizados na tomografia computadorizada. Os resultados obtidos sugerem que a irradiação da câmara a 50% do seu comprimento sensível, é a melhor opção para a realização da calibração deste tipo de câmaras. Os resultados obtidos permitem ao LMRI estar em condições de participar numa comparação interlaboratorial das qualidades estudadas.

Introduction: School climate refers to the quality of school life and it is based on patterns of people's experiences in school, and involves norms, goals, values, interpersonal relationships, teaching and learning practices and institutional structures. Poor school climate has been associated with learning disabilities, school drop out, substance abuse, non-compliance of school rules, depression, low self-esteem and bullying in previous studies. However, there are no validated instruments to assess school climate in Brazil. The Delaware School Climate Survey-Student (DSCS-S) is an instrument composed by 78 items, divided into: Scale I - School Climate; Scale II - School Techniques; Scale III - Bullying and Cyberbullying Victimization; and Scale IV - Cognitive, Behavioral and Emotional Student Engagement. Objective: This study aims to investigate evidences of validity of this survey in Brazil, as well as investigate associations of school climate dimensions with characteristics of schools and students in Southern Brazil. Method: This dissertation comprised three manuscripts. The first describes the cross-cultural adaptation and the search for evidence of content validity of the DSCS-S. The second describes the investigation of the psychometric properties of the DSCS-S, more specifically the evidence of construct validity through exploratory and confirmatory factor analysis. The third discusses how the DSCS-S dimensions correlated with each other and how they associated with characteristics of Brazilian students. The sample consisted in 436 students, aged from 9 to 18 years old (M = 12. 98, SD = 1. 80; 51. 8% girls), from 2 private schools (50. 5% of the students assessed) and four public schools located in the cities of Porto Alegre, Gramado and Viamão (Rio Grande do Sul state, Brazil). The DSCS-S and a demographic data questionnaire developed for this study were applied. Procedures for a cross-cultural adaptation were adopted and also evidences of validity of the instrument were investigated along with correlations between the DSCS-S dimensions and student characteristics such as age, gender, number, occurrence of repetition and type of education (private or public).Results: The cross-cultural adaptation resulted in a Portuguese version that is consistent and showed evidence of content validity and proper congruence between the expert committee. Confirmatory factor analysis showed more acceptable fit indices than the exploratory factor analysis. Results indicate (1) the importance of follow a rigorous crosscultural adaptation method to ensure instruments’ content validity; (2) that the Portuguese version of the DSCS-S showed evidences of content and construct validity; and (3) that school strategies to promote a positive climate should focus on student engagement and the development of social-emotional learning school techniques. Conclusion: The DSCS-S can attend Brazilian schools’ demand for climate assessments and support the development of more assertive education policies and strategies that will foster a positive school climate.
Introdução: O clima escolar refere-se à qualidade da vida escolar e está baseado no padrão de experiências das pessoas na escola, envolvendo normas, metas, valores, relacionamentos interpessoais, práticas de ensino e aprendizado e estruturas institucionais. Climas escolares negativos, a partir de estudos prévios, foram associado a dificuldades de aprendizagem, evasão escolar, uso de substâncias psicoativas, desacato a regras escolares, sintomas de depressão, baixa autoestima e bullying. Entretanto, não existem instrumentos validados para avaliação de clima escolar no Brasil. O Delaware School Climate Survey-Sudent (DSCS-S) é um instrumento composto por 78 itens, divididos em: Escala I - Clima Escolar; Escala II - Técnicas Escolares; Escala III - Vitimização no bullying e cyberbullying; Escala IV - Engajamento Estudantil cognitivo, comportamental e emocional. Objetivo: Este estudo objetiva investigar evidências de validade deste instrumento no Brasil, assim como investigar associações das dimensões do clima escolar com características de escolas e alunos do sul do Brasil.Método: Esta dissertação é composta por três manuscritos. O primeiro descreve a adaptação transcultural e a investigação de evidências de validade de conteúdo do DSCS-S. O segundo descreve a investigação das propriedades psicométricas do instrumento, mais especificadamente das evidências de validade de construto do DSCS-S mediante análise fatorial confirmatória e exploratória. O terceiro aborda como as dimensões do DSCS-S correlacionam entre si e se associam com características dos alunos brasileiros. Participaram da pesquisa 436 alunos (51,8% meninas) de 9 a 18 anos (M = 12,98; DP = 1,80), de 2 escolas privadas (50,5% dos alunos avaliados) e 4 escolas públicas de Porto Alegre, Gramado e Viamão/RS. Foram aplicados o DSCS-S e um questionário de dados sociodemográficos elaborado para esta pesquisa. Foram adotados procedimentos para a adaptação transcultural, investigadas evidências de validade do instrumento e também correlações entre as dimensões do DSCS-S e características dos alunos como idade, gênero, série, ocorrência de repetência e modalidade de ensino (privado ou público).Resultados: A adaptação transcultural originou uma versão em português que é consistente e apresenta validade de conteúdo, assim como foi observada adequada congruência entre juízes. As análises fatoriais confirmatórias apresentaram índices de ajuste mais aceitáveis do que as exploratórias. Resultados indicam (1) a importância de um rigoroso método de adaptação transcultural de instrumentos para garantir a validade de conteúdo; (2) a existência de evidências de validade de conteúdo e de construto do DSCS-S para a língua portuguesa do Brasil; e (3) que estratégias para promover um clima escolar positivo devem focar no engajamento dos alunos e no desenvolvimento de técnicas escolares focadas no aprendizado sócio-emocional. Conclusão: O instrumento DSCS-S pode atender a demanda das escolas brasileiras por avaliações de seu clima e auxiliar no desenvolvimento de políticas de educação e na concepção de estratégias e programas escolares mais assertivos e que promovam o clima escolar positivo.

>Magister Scientiae - MSc
This study investigated the current knowledge, perceptions, and practices of Risk-Based Monitoring (RBM) using written and verbal responses to an ethics review board approved questionnaire. Responses were collected from individuals involved in the practice, oversight, and implementation of clinical trial monitoring in the USA. RBM was viewed as a positive force with a bright future. However the results suggested that a renewed focus on change management strategies is needed to ensure RBM practices penetrate all levels of clinical trial management. The site sponsor/site operational relationship was identified as a key RBM component. Shortcomings in this relationship were identified as significant operational barriers to effective RBM practice. Respondents indicated that current RBM training efforts were lacking. Because RBM is new and its practices deviate significantly from the past total monitoring efforts, both industry and the clinic need to work harder to ensure that everyone involved in clinical trial monitoring understands these differences. Fortunately, overcoming the identified barriers will not require massive changes to current RBM practice. By refocusing efforts on the sponsor/CRO and investigative sites to attain RBM governance, develop quality control plans, institute an optimal RBM platform, and improve training, the true promise of RBM is within reach. Each of these are critical pieces to an effective RBM implementation methodology and correcting initial stumbles in their implementation can assure the RBM future is as promised.

Abstract:

Climate change is one of the great challenges facing agriculture in the 21st century. The goal of this study was to produce projections of crop yields for the central United States in the 2030s, 2060s, and 2090s based on the relationship between weather and yield from historical crop yields from 1980 to 2010. These projections were made across 16 states in the US, from Louisiana in the south to Minnesota in the north. They include projections for maize, soybeans, cotton, spring wheat, and winter wheat. Simulated weather variables based on three climate scenarios were used to project future crop yields. In addition, factors of soil characteristics, topography, and fertilizer application were used in the crop production models. Two technology scenarios were used: one simulating a future in which crop technology continues to improve and the other a future in which crop technology remains similar to where it is today. Results showed future crop yields to be responsive to both the different climate scenarios and the different technology scenarios. The effects of a changing climate regime on crop yields varied both geographically throughout the study area and from crop to crop. One broad geographic trend was greater potential for crop yield losses in the south and greater potential for gains in the north. Whether or not new technologies enable crop yields to continue to increase as the climate becomes less favorable is a major factor in agricultural production in the coming century. Results of this study indicate the degree to which society relies on these new technologies will be largely dependent on the degree of the warming that occurs. Continued research into the potential negative impacts of climate change on the current crop system in the United States is needed to mitigate the widespread losses in crop productivity that could result. In addition to study of negative impacts, study should be undertaken with an interest to determine any potential new opportunities for crop development with the onset of higher temperatures as a result of climate change. Studies like this one with a broad geographic range should be complemented by studies of narrower scope that can manipulate climatic variables under controlled conditions. Investment into these types of agricultural studies will give the agricultural sector in the United States greater tools with which they can mitigate the disruptive effects of a changing climate.

Abstract:

The purpose of this study was to understand the role of resilience and protective factors (PFs) in the life of women who have experienced childhood maltreatment (CHM). A further purpose was to understand how women who faced CHM develop resilience, and how the proper use or misuse of PFs later affected their adult relationships, whether intimate, social, or familial. Resiliency theory was the theoretical foundation that informed the study. A qualitative methodology with an interpretative phenomenological analysis design was used in this study. Participants included 7 women who were recruited through social media support groups for adult survivors of child abuse. Participants were interviewed via telephone and Skype. Data from these interviews were analyzed and coded according to the interpretative, phenomenological method. Five main themes emerged, providing awareness as to the development of resilience and PFs as well as the role of resilience and the impact PFs have on relationships survivors entered as adults. The themes included: trauma results in resilience and healing through helping others; time and interventions heal perception of abuse; guarding trust to avoid hurt as the effects of CHM lasts a lifetime; support is key then and now; and the effects of CHM and protective factors affect healthy adolescent and adult relationships. The findings were compared with existing literature to recommend ways therapeutic practitioners and social service workers can provide early interventions for those exposed to CHM and help them move past the starting point of unpacking the trauma to the ending of point of sustaining healthy adult relationships.

Abstract:

The importance of studying the physico-chemical properties of nano-dimensional materials has gained significant attention in the fields of semiconductors, pharmaceuticals, materials science, and atmospheric chemistry owing to the differences in physical properties between macro- and nano-dimensional solids. Nonetheless, direct studies of physical properties of materials at nanoscale is limited in part due to their inherent size constraints and experimental limitations. However, development of atomic force microscopy (AFM) led to the implementation of methods to characterize a wide range of physical properties, including – but not limited to – mechanical properties, electrical properties, viscoelastic properties, and surface tension. Herein, the dissertation focuses on AFM-based method development for characterization of atmospheric particles as well as understanding the relationship between structure and physical properties of organic solids at both macro- and nano-dimensions. In the atmospheric chemistry realm, the combined aerosol effect on the climate and environment has significant uncertainty in part due to lack of direct characterization of their physico-chemical properties. The difficulty in assessing the physical and chemical properties arises due to the presence of diversified aerosol sources, which in turn influences the size, morphology, phase states and chemical compositions. Sea spray aerosols (SSAs) are the second-largest source of aerosols in the atmosphere. Studying SSAs – especially in submicrometer-dimensions – requires high-resolution microscopy techniques such as AFM. AFM can be used for imaging of individual aerosols, quantifying organic volume fraction for core-shell morphologies, measuring water uptake, quantifying surface tension of individual droplets, and measuring mechanical and viscoelastic properties of materials. Herein, we employed AFM-based morphology and force spectroscopy studies to correlate the 3D morphology, phase state, and viscoelastic properties of selected single-component chemical systems found in sea spray aerosol (SSA). We established a quantitative framework toward differentiation of the solid, semisolid and liquid phase states of individual particles by utilizing both relative indentation depth (RID) and viscoelastic response distance (VRD) data obtained from the force−distance plots. Moreover, we established a semi-quantitative and quick phase assessment by measuring the aspect ratio (AR) that refers the extent of particle spreading as a result of impaction. Overall, the established AFM-based quantitative and semi-quantitative phase identification method can be utilized to assess the phases of aerosols irrespective of chemical identity. Next, we investigated the factors that may control the electrical and mechanical properties of pharmaceutical and organic semiconducting materials in nano- and macro-dimensions. Understanding the structure-property relationship of materials, especially in the nano-dimension, is necessary for proper drug design and development of organic semiconducting materials. In this context, cocrystals provide a means to modulate the physico-chemical properties of organic solids. For example, the modulation of the mechanical properties is important in the pharmaceutical industry for improving the tabletability. The mechanical properties may be affected by packing arrangement, interaction strength and type, and atomic and chemical composition. Herein, we report the influence of alkane and alkene functional groups on the mechanical properties of organic solids based on salicylic acid (SA). The approach affords both isostructural and polymorphic solids. The isostructural alkane functional solid exhibits a two-fold larger Young’s modulus (YM) compared to the cocrystal with the alkene, where the YM refers to the stiffness of the material. Here, the higher YM values are attributed to the presence of a bifurcated weak C-H···O interactions involving the alkane and neighboring SA molecules. On the other hand, in the case of alkene polymorphisms, molecular packing with column arrangement shows higher YM values compared to the herringbone arrangements. Thus, functional groups and crystal arrangements influence the stiffness of the solid organic cocrystals. Moreover, we report the modulation of mechanical properties of salicylic acid (SA) through cocrystallization by variation of propane and butane functionality with bipyridine coformers. We show that the variation of propane and butane functionality in bipyridine coformer with salicylic acid leads to synthesis of cocrystal and salt-cocrystal, respectively. The AFM nanoindentation study revealed that the Young’s modulus values follow the order salicylic acid < cocrystal << salt-cocrystal. The highest Young’s modulus values of the salt-cocrystal, among the studied systems, are attributed to the presence of strong N+–H···O– and O–H···O– interactions. On the other hand, higher Young’s modulus values of the propane-based cocrystal compared to the macro-dimensional salicylic acid are attributed to the stronger O–H ···N hydrogen bonding. Thus, homologous alkane functional groups can influence the mechanical properties of the organic solid crystals. Additionally, in situ solid-solid polymorphic phase transformation and nucleation of a metastable and elusive polymorph of SA cocrystals in combination with 4,4’-bipyridine were studied. Understanding the solid-solid phase transformations and nucleation mechanisms are important for proper control over the parameters associated with the synthesis of targeted crystalline solids with desired crystal structure. Using in situ powder X-ray diffraction (PXRD) and terahertz time domain spectroscopy (THz-TDS) data we showed that the Form II polymorph transforms to Form I over time. AFM imaging and nanoindentation techniques were utilized to follow and quantify in real-time the solid-solid polymorphic transformation of the metastable Form II to the thermodynamically stable Form I on a single crystal basis. AFM in situ single crystal data revealed that the metastable Form II has a rod-shaped morphology and relatively high elasticity (Young’s modulus), which transforms to prism-shaped nanocrystals of much smaller sizes with significantly reduced elasticity. The AFM imaging reveals that the single crystals on the order of 80-150 nm to undergo catastrophic changes in morphology that are consistent with cracking and popping owing to a release of mechanical stress during the transformation. The nucleation mechanism for the polymorphic transformation is not spatially localized and occurs over the entire crystal surface. The higher mechanical properties of the metastable Form II is due to the presence of the additional interlayer C-H···O interactions. Furthermore, we have studied the electrical properties of boron-based cocrystals. More specifically, cocrystallization of a nonconductive 2,4-difluorophenylboronic ester catechol adduct of a 4,4’-bipyridine (BEA) host with two aromatic semiconducting guests (pyrene and tetrathiafulvalene) generated conductive cocrystals with variable charge carrier mobilities. Charge carrier mobilities of the cocrystals with either pyrene or tetrathiafulvalene were measured using conducting probe AFM (CP-AFM). The incorporation of π-rich aromatic guests through face-to-face and edge-to-face π-contacts results in electrically conductive cocrystals. The cocrystal with tetrathiafulvalene as a guest shows approximately 7 times higher charge carrier mobility than the cocrystal with pyrene. Overall, the current dissertation demonstrates the AFM-based method development and applications towards materials characterization to measure the morphological, electrical, mechanical, and phase-states at both nano- and macro-dimensions. The high spatial precision of the methods developed enables us to better understand the controlling factors for materials design and processing across nano- and macro-dimensions.

Full text

Abstract:

This thesis offers an explanation for why urban settlement in Somaliland's capital city of Hargeisa is segregated along clan lines. The topic of urban segregation has been neglected in both classic Somali studies, and recent studies of post-war state-building and governance in Somaliland. Such negligence of urban governance in debates over state-making stems from a predominant focus on national and regional levels, which overlooks the institutions governing cities. Yet urban governance can provide key insights into the nature and quality of interaction between people and the local state, and the processes of making and unmaking of Somali urban spaces. Given the rapid urban growth in the Somali populated territories, I propose a shift in focus to explore city spaces, as a means of deepening understanding of Somali social, political and spatial organisation. In advancing this proposed shift, the thesis scrutinises the nexus between governance and segregation in Hargeisa, drawing on urban ethnographic methods, interview and archival sources. I argue that segregation in the city can be understood as the spatial manifestation of governance practices across colonial and postcolonial periods, in intersection with bottom up processes, particularly the quest for security and peacebuilding in what is largely characterised as a hybrid order. The concept of hybrid governance – while capturing important aspects of control over city space - is often insufficiently historicised and politicised to convey the complex intersection of state institutions, clan and sub-clan allegiance and traditional authorities. My analysis thus situates recent urban governance and conflicts over land in a longer history of municipal governance, urban land administration and conflict adjudication. This historical perspective is important for the understanding of how segregation has been reproduced over time, and adds a new dimension to the understandings of the drivers and dynamics of Hargeisa's spatial character.

Abstract:

Dieser vor Jahrzehnten in der ehemaligen DDR oft und gern und mit lang gezogenem „U“ im letzten Wort zitierte und leicht abgewandelte Zitat eines Verses von Conrad Ferdinand Meyer beschreibt die Situation der Autoren, Kulturpolitiker, Funktionäre, Rundfunkredakteure, Verlagsmitarbeiter usw. sehr genau. Inmitten ständig sich verändernder Vorgaben, Richtlinien, Anweisungen, Entwicklungskonzepte und ‚Rahmenbedingungen‘ mussten sie alle im großen Unsinn versuchen, etwas Sinnvolles und künstlerisch möglichst Wertvolles zu artikulieren, zu veröffentlichen und dem Publikum zur Kenntnis zu geben und das immer unter dem Hanns Eisler’schen Diktum: „Ändere die Welt, sie braucht es.“ Neue Musik in der DDR war immer politisch, sie war immer mehr oder weniger direkt gegen den Staat und seine Engstirnigkeit gerichtet, ebenso wie sie immer auf „Welt“, also auf Überwindung der Systemgrenzen gerichtet war und das war politisch, aber auch reisetechnisch gemeint. Der oben zitierte Spruch deutet die Zwänge an, in denen alle Künstler fortlaufend standen. Denn jeder Künstler war aus Sicht von Partei und Regierung wichtig genug, um die Massen oder wenigstens Teile davon für die ‚beste Sache der Welt‘ zu begeistern und mit künstlerischen Mitteln zu beeinflussen. Gleichzeitig aber gegen ganz konkrete Repressionen, Schikanen und Bevormundungen sich fortlaufend ganz individuell wehren zu müssen, war das Alltagsgeschäft aller, die an der ‚Kulturfront‘ tätig waren. Dabei gab es geschickte und ungeschickte Kollegen, mutige und weniger mutige, Helden, Heroen, Schlaumeier, Trickser und Dünnbrettbohrer wie überall in der Welt, wo Menschen zusammentreffen und zusammen arbeiten. Der Spruch, der seinen Widerspruch schon in sich trug, verwies mit List auf die zahlreichen Irrwege und Pannen, die die mühsame, und eben nicht widerspruchslose Entwicklung des kleinen Landes fortwährend begleiteten und seitens der Funktionäre als historisch bedingte ‚Widersprüche innerhalb der Entwicklung‘ abgetan bzw. heruntergespielt wurden. Die vier Generationen von Komponisten, die die Entwicklung der Neuen Musik in der DDR prägten, hatten verschiedene Ausgangsvoraussetzungen, sie hatten unterschiedliche Vorstellungen über die Zukunft des Landes und über ihre eigene Zukunft gehabt, sie haben vollkommen verschiedene Strategien entwickelt, um sich bemerkbar zu machen, und sie hatten verschiedene soziale Umfelder, in denen sie leben und arbeiten mussten.

Abstract:

An Giang province is one of the largest rice producer regions in Vietnam with 600,000 hectares of paddy field and 4 million tons of rice production every year. The rice milling industry generates a huge amount of rice husk (~23% of paddy rice). The rice husk is currently used as fuel around the province generating rice husk ash (RHA) which causes environmental and health issues. This study focuses on surveying and analyzing the current situation for utilization, management, treatment, and awareness of enterprises and community about generated RHA via a household investigation method. The results showed that, in average, a factory generates 862.4 tons of RHA per year, whereas half of them are reused or are sold for re-utilization in other factories, 56.3% are disposed in the private landfill of the factory, and 1.6 to 6.3 % are directly disposed to nearby rivers or in soil. Most of the interviewed citizens reported that they were aware of the RHA impact on the environment nevertheless, only 2% knew that RHA can be re-utilized for other purposes. Therefore, it is necessary to raise public awareness about the reuse and utilization of RHA to reduce the environmental impact and contribute to the sustainable development of the rice production.
Tỉnh An Giang là một trong những vựa lúa lớn nhất Việt Nam, với diện tích khoảng 600.000 ha và sản lượng gần 4 triệu tấn/năm. Cùng với lúa, lượng trấu phát sinh từ quá trình xay xát đang được tái sử dụng làm nhiên liệu đốt cho các quá trình sản xuất khác ở địa phương. Tuy nhiên lượng tro sau quá trình đốt nhiên liệu trấu cũng đang tạo nên một áp lực lên chất lượng môi trường. Do vậy, nghiên cứu này tập trung vào việc khảo sát và phân tích hiện trạng sử dụng, quản lý, xử lý và nhận thức của cơ sở sản xuất hay cộng đồng đối với vấn đề phát thải tro trấu thông qua phương pháp điều tra thực tế. Kết quả cho thấy trung bình mỗi cơ sở phát sinh 862,4 tấn tro trấu/năm với khoảng phân nửa trong số đó được tái sử dụng, 56,3% xử lý bằng cách chôn lấp; 1,6% đến 6,3% xử lý bằng cách đổ bỏ. Hầu hết những người được phỏng vấn biết việc phát thải tro trấu có ảnh hưởng đến chất lượng môi trường, tuy nhiên chỉ có 2% hộ nhận thức được tro trấu có thể tái sử dụng cho các mục đích khác. Điều này cho thấy cần có biện pháp nâng cao nhận thức của cộng đồng đối với việc tái sử dụng tro trấu, nhằm góp phần giảm áp lực của phát thải lên môi trường và đóng góp vào sự phát triển của ngành sản xuất lúa gạo theo định hướng bền vững.

Abstract:

В Україні основним видом питного водопостачання населення є централізоване з використанням для виготовлення питної води поверхневих та підземних вод з глибоко залеглих водоносних горизонтів. Відомо, що якість водопровідної питної води залежить від різних чинників, основними з яких є стан та якість води джерела питного водопостачання, ефективність водоочисних споруд та технології водопідготовки, санітарно-технічний стан водопровідних мереж. В сучасних умовах усі ці чинники не відповідають нормативним вимогам, внаслідок чого створюються несприятливі умови для отримання питної води належної якості. Сумська вода – одна з кращих на Лівобережній Україні, оскільки надходить з артезіанських свердловин. Але необхідно зазначити, що мережі водопостачання в межах міста надзвичайно зношені, що суттєво впливає на якість питної води доведеної до споживача. У зв'язку з цим виникає нагальна потреба у дослідженні по визначенню стану водоводів та його впливу на якість питної води у кранах кінцевого споживача. Мета роботи - оцінка якості питної води в мережах КП «Міськводоканал» на основі аналізу сучасного стану системи водопостачання.

Abstract:

Смертність в Україні найвища при ВГ В і становить 0.19 на 100 тис. нас., при ВГ А вона у 4 рази, а при ВГ С – у 14 разів нижча (відповідно 0.05 і 0.013 на 100 тис. нас.). Максимальна смертність при ВГ В спостерігається у віці 60-64 років, при ВГ С – у 30 – 34 років, при ВГ А – дитячий вік. При ВГ В і ВГ С помирають переважно чоловіки. Щорічний показник смертності за період від 1990 до 2013 рр. скоротився при ВГ А на 21.5 %, при ВГ В – на 12.2 %, а при ВГС – навпаки зріс на 6,2 %.

Abstract:

Introduction: Treatment methods of anterior urethral strictures in adults have undergone considerable changes in the recent past. Our goal was to determine national practice patterns among German urologists and to compare results with the results of prior international surveys. Methods: We conducted a survey on the management of urethral strictures among German urologists. Results: Eight hundred forty-five urologists, representing about 14.6% of German urologists, answered the survey. Most common procedures were direct vision internal urethrotomy (DVIU; 87.2%), blind internal urethrotomy (57.5%), dilatation (56.3%), ventral buccal mucosa graft urethroplasty (31.6%) and excision and primary anastomosis (28.9%). In case of a 3.5-cm bulbar stricture and in the case of a 1-cm bulbar stricture after 2 failed DVIUs, a consecutive urethroplasty was significantly more often favoured compared to transurethral treatment options (44.9 vs. 21.3% and 59.4 vs. 8.3%, both p < 0.001). Conclusion: Open urethral reconstruction reveals to be a more common method in practice nowadays. Adherence to recommended treatment algorithms improved in comparison to prior surveys.

Abstract:

This study sought to understand the history of the establishment and development of the Center for Early Childhood Education Ipê Amarelo at the Federal University of Santa Maria, seeking evidence of its recent history, for, as appropriate, to analyze the identity of this space in the University. In the theoretical framework was aimed the contextualize the childhood History the Child and Early Childhood Education as well as the contributions of Public Policy and Legislation for the advancement of early childhood education in the country. It was also to demonstrate the route of the College Creches in Federal Universities, discussion of its role and academic identity, and in particular the creation of the Center for Early Childhood Education Ipê Amarelo and the prospects of maintaining this space at the University. The methodology adopted was based on the approach of historical-cultural, based on the concepts of interaction Vygotskyanas subject-world. Research in this approach allowed us to understand the phenomenon as part of a larger historical process, relating it with the social and cultural transformations produced by mankind. Was used as data collection techniques to document analysis, through institutional documents and legislation, semi-structured interviews with individuals involved in the implementation and establishment of the institute audio recording. The research results led to conclude that throughout the process of formation and development of the Ipê Amarelo in the University, many were trodden paths, different conceptions permeated the managements of the Center, who followed the historical evolution of Early Childhood Education in Brazil, and Public Policy Legislation. It was noticed over the years significant changes in conceptions of Children, Child and Early Childhood Education, and the pursuit of his teachers at the University by a space that allied education and care of children with training, because it is historically an area of educational practices. Through the constant struggle of the current management team for the recognition and consolidation of their identity, won the acknowledgment of the Ipê Amarelo as a Unit of Early Childhood Education, character education, where the child is seen as subjects of rights, the protagonist of his time and its history. The Unit is currently seeking to make the link between education, research and extension in line with the objectives of the University, thus consolidating its academic role and identity.
Este estudo procurou compreender a história da constituição e desenvolvimento do Núcleo de Educação Infantil Ipê Amarelo na Universidade Federal de Santa Maria, buscando elementos de sua história recente, para, a partir disso, analisar a identidade deste espaço na Universidade. No referencial teórico buscou-se contextualizar a história da Infância, da Criança e da Educação Infantil, bem como as contribuições das Políticas Públicas e Legislação para o avanço da Educação Infantil no país. Tratou-se também de demonstrar o percurso das Creches Universitárias nas Instituições Federais de Ensino, a discussão de seu papel e sua identidade acadêmica e, em especial, a criação do Núcleo de Educação Infantil Ipê Amarelo e as perspectivas de manutenção deste espaço na Universidade. A Metodologia adotada pautou-se pela abordagem de caráter histórico-cultural, tendo por base as concepções Vygotskyanas de interação sujeito-mundo. A pesquisa nesta abordagem possibilitou a compreensão do fenômeno como parte de um processo histórico maior, relacionando-o com as transformações sociais e culturais produzidas pela humanidade. Utilizou-se como técnicas de coleta de dados a análise documental, através dos documentos institucionais e legislação vigente, entrevistas semi-estruturadas com os sujeitos envolvidos na implementação e constituição do Núcleo e gravação em áudio. Os resultados da investigação levaram a concluir que durante todo o processo de constituição e desenvolvimento do Ipê Amarelo na Universidade, muitos caminhos foram trilhados, diferentes concepções perpassaram as gestões do Núcleo, que acompanharam a evolução histórica da Educação Infantil no Brasil, das Políticas Públicas e da Legislação. Percebeu-se no decorrer dos anos mudanças significativas nas concepções de Infância, Criança e Educação Infantil, e a busca de seus educadores por um espaço na Universidade que aliasse a educação e o cuidado das crianças com a formação, por ser historicamente um espaço de práticas educativas.Através da luta constante da atual equipe gestora pelo reconhecimento e consolidação de sua identidade , conquistou-se o reconhecimento do Ipê Amarelo como uma Unidade de Educação Infantil, de caráter educativo, no qual a criança é vista como sujeito de direitos, protagonista de seu tempo e de sua história. A Unidade atualmente busca fazer a articulação entre o ensino, a pesquisa e a extensão em consonância com os objetivos da Universidade, consolidando assim seu papel e identidade acadêmica.

Context and Objectives: Nowadays, phototherapy has been used to enhance physical performance and to accelerate recovery after exercise. The aim of this study was to evaluate the effects of LED therapy (850 nm) and low power (50 mW) on the physical performance of soccer players after 6 weeks of soccer training. Study design/materials and methods: a randomized, double-blind clinical trial, controlled with placebo study was conducted. Sixteen soccer athletes aged between 14 and 16 years participated in the study. The athletes were randomly allocated into 2 groups: (i) training group associated with the LED therapy (LEDT) and (ii) training group associated with the placebo LED therapy (placebo). LED therapy or placebo were applied on the quadriceps, hamstrings and sural triceps immediately after training, twice a week during 6 consecutive weeks (12 sessions of therapies). The LED device (850nm, 50 mW, 30 s on each muscle group and energy of 75 J) was used for phototherapy. The functional performance was evaluated through the jump platform (vertical jump) and photocells (10 and 35 meter races) in the period pre and post training plus LED therapy or placebo therapy. Results: the LEDT Group significantly increased the height (cm) of vertical jump (from 36.02±3.95 to 39.20±4.52; p<0.001) and the muscle power (W) (from 382.62±31.82 to 417.62±31.19; p=0.003) in this same test. The LEDT showed significant increases for the average speed (m/s) at 10 m race (from 5.94 ± 0.35 to 6.13 ± 0.45; p<0.001) and 35 m (from 7,43 ± 0,32 to 7.51 ± 0.32; p=0.003). The Placebo group showed significant increases only for the height of vertical jump (from 36.25±4.55 to 37.38±4.26; p=0.017). Conclusion: LED therapy applied after physical training can improve functional performance of soccer players, evidenced by improvements of the jump height, muscle power and speed racing.
Contexto e Objetivos: Recentemente, a fototerapia por laser e LEDs de baixa potência vem sendo utilizada para aumentar o desempenho físico e acelerar a recuperação pós-exercício. Este estudo consiste em investigar os efeitos da terapia LED, na faixa do infravermelho (850 nm) e baixa potência (50 mW) sobre o desempenho físico de atletas de futebol após 06 semanas de treinamentos específicos desse esporte. Desenho do estudo/Materiais e métodos: Foi realizado um estudo clínico, randomizado, duplo cego e com placebo. Participaram do estudo 16 atletas de futebol com idade entre 14 e 16 anos de idade. Os atletas foram alocados randomicamente em 2 grupos iguais: (i) grupo treinamento associado à terapia LED (LEDT) e (ii) grupo treinamento associado à terapia LED placebo (Placebo). A terapia LED ou placebo foi aplicada sobre o quadríceps femoral, isquiotibiais e triceps sural imediatamente após os treinamentos, 2 vezes por semana, durante 6 semanas consecutivas, totalizando 12 sessões de terapia. Foi utilizado um dispositivo contendo um arranjo de 50 LEDs de baixa potência (850nm, 50 mW, 30 s sobre cada grupo muscular e energia de 75 J). O desempenho funcional doa atletas em salto vertical e em corridas de 10 e 35 metros foram realizados através da plataforma de salto e fotocélulas no período pré e pós-treinamento e terapia LED. Resultados: O grupo LEDT aumentou significativamente a altura (cm) do salto vertical (de 36,02±3,95 para 39,20±4,52; p<0,001) e a potência muscular (W) (de 382,62±31,82 para 417,62±31,19; p=0,003) nesse mesmo teste. A velocidade média (m/s) da corrida de 10m aumentou significativamente no grupo LEDT (de 5,94±0,35 para 6,13±0,45; p<0,001) assim como para a corrida de 35m (de 7,43±0,32 para 7,51±0,32; p=0,003). O grupo Placebo mostrou aumento significativo apenas para a altura do salto vertical (de 36,25±4,55 para 37,38±4,26; p=0,017). Conclusão: A fototerapia por LED de baixa potência aplicada após o treinamento físico pode aumentar o desempenho físico dos atletas de futebol, evidenciado pelo aumento da altura de salto, potencia muscular e velocidade de corrida.
