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.

Texto completoElectro 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

Texto completoLearning 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.

Texto completoSi 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.

Texto completoAbstract 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.

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.

Objetivo: analisar os parâmetros do alinhamento sagital espinopélvico e os seus impactos na espondilolistese lombar degenerativa. Metodologia: pesquiza computorizada na base de dados PubMed. Após a seleção dos estudos foi efetuada uma análise de qualidade metodológica com o Critical Appraisal Skills Programme (CASP). Resultados: nesta revisão foram integrados 9 artigos, com um total de 2445 pacientes de idades compreendidas entre 18 e 88 anos, dos quais se recolheram dados com o intuito de avaliar a correlação dos componentes biomecânicos da sacroilíaca com a presença de espondilolistese lombar. 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 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.

Texto completoIntroduction: 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.

Texto completoThis 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.

Texto completoTỉnh 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.

Texto completoEste 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.

Texto completoContext 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.
