In Rio de Janeiro?s state, 48% of the territory is constituted by Atlantic slope, where were registered 16 air basins with specific environmental features, distributed in 20% of the area. Based on the conformation of morphometrics parameters the air basins were grouped, by Multivariate Analysis - Cluster, with Euclidean distance of 48%, significance level of 95% and correlation coefficient of 0.7132, in 5 groups with similar forms. To evaluate the hydrologic effects within the air basins, it was used as a study case, the air basin of Angra dos Reis, where the magnitude of the interception of clouds was measured in the escape zone from the topographic divide of the Pirai river basin (leeward), in different distance away, with and without natural barriers, during the winter and summer. It was used vertical intercept sampling area equivalent to 0.45% of the forests in the region. The variation of the removal of the topographic divide occurred until 500 m of altitude, this limit may be the end of the escape zone and the beginning of the air basin distribution zone. The effect of air basin represented additional of 44% of the volume of rain in topographic divide (point 1), 39% at 4.5 km (point 2) and 42% at 7.5 km (point 3) of the point 1, in concordant direction of the flow. The effect of the orography in the trajectory of the winds, varied in an irregular way in winter and in summer, maintaining differential of 23% and 77% in point A (obstruction of 85% of the cross section) and 32% and 68% in point B (obstruction of 80% of the cross section). In areas under the influence of air basins, the variables and environmental processes can be crucial to offer environmental services in drainage basins. / A Bacia A?rea ? um espa?o tridimensional que conduz e distribui os ventos sobre as bacias hidrogr?ficas. No Estado do Rio de Janeiro, 48% do territ?rio ? composto pela vertente Atl?ntica, onde foram registradas 16 bacias a?reas com caracter?sticas ambientais espec?ficas, distribu?das em 20% da ?rea. Baseado na conforma??o de par?metros morfom?tricos as bacias a?reas foram agrupadas, atrav?s de An?lise Multivariada ? Cluster, com dist?ncia Euclidiana de 48%, n?vel de signific?ncia de 95% e coeficiente de correla??o de 0,7132 em 5 grupos com formas similares. Para avaliar os efeitos hidrol?gicos dentro das bacias a?reas, utilizou-se como estudo de caso a bacia a?rea de Angra dos Reis, onde a magnitude da vari?vel intercepta??o das nuvens foi medida na zona de escape, a partir do interfl?vio da bacia hidrogr?fica do rio Pirai (sotavento), em dist?ncias de afastamento distintas, com e sem barreiras orogr?ficas, durante o inverno e ver?o. Utilizou-se ?rea amostral de intercepta??o vertical equivalente a 0,45% das florestas da regi?o. A varia??o do afastamento do interfl?vio ocorreu at? desn?vel de 500 m em altitude, podendo ser este limite o fim da zona de escape e in?cio da zona de distribui??o da bacia a?rea. O efeito da bacia a?rea representou adicional de 44% em volume de chuva no interfl?vio (ponto 1), 39% a 4,5 km (ponto 2) e 42% a 7,5 km (ponto 3) do ponto 1 em dire??o concordante ao sentido do fluxo. O efeito da orografia no corredor variou de forma irregular no inverno e no ver?o, mantendo diferencial de 23% e 77% no ponto A (obstru??o de 85% da se??o transversal) e 32% e 68% , no ponto B (obstru??o de 80% da se??o transversal). Em ?reas sob influ?ncia de bacias a?reas, as vari?veis e processos ambientais podem ser determinantes para ofertar servi?os ambientais nas bacias hidrogr?ficas.

A evolução das tecnologias, junto com a expansão do uso da internet têm nos propiciado uma gama de ferramentas que podem ser utilizadas no ensino-aprendizagem na Educação Básica. Em particular, no contexto do ensino-aprendizagem da Estatística no Ensino Médio pode-se verificar a existência de numerosa quantidade de recursos educacionais para tal. Portanto, o problema que está colocado para o professor diz respeito à seleção criteriosa destes recursos para a sua utilização em sala de aula. Nesse sentido, por meio deste trabalho esperamos contribuir para o avanço deste tema propondo diferentes critérios de análise. O conjunto de critérios estabelecido mostrou-se consistente e adequado para a análise do recurso investigado e, podemos concluir que dependendo da qualidade do recurso e como este será utilizado pelo professor em sala de aula, ele poderá representar uma efetiva contribuição para o ensino-aprendizagem da Estatística no Ensino Médio. Por outro lado, corre-se o risco que se um recurso não é previamente analisado, ele poderá eventualmente favorecer o desenvolvimento de conceitos estatísticos incorretos, bem como agravar algumas das dificuldades que já se façam existentes na sua aprendizagem. / The evolution of technologies, along with the spread of the internet use, has provided us a wide range of tools that may be used in the teaching-learning process on basic education. Particularly, in the context of the teaching-learning process of Statistics in high school, it is possible to verify the existence of a huge number of open educational resources for that purpose. Thus, the problem that teachers have to face concerns the careful assessment of these resources for their use in the classroom. Therefore, through this dissertation, we aim to contribute to the advance of this topic proposing different criteria of analysis. The established set of criteria proved to be consistent and appropriate for the analysis of the investigated resource. We are able to conclude that depending on the quality of the resource and how it will be used by the teacher in the classroom, it may represent an effective contribution to the teaching-learning process of Statistics in high school. On the other hand, there is a risk that if a resource is not previously analyzed, it may eventually endorse wrong statistics concepts, as well as aggravate pre-existent difficulties in their learning process.

<p>Humanitär intervention är ett begrepp inom internationella relationer som väcker många känslor och frågor. Trots att idén om att använda våld för att stoppa brott mot de mänskli-ga rättigheter kan verka attraktivt från ett moraliskt perspektiv, vilket man i århundraden har gjort, har denna praktik varit synnerligen oregelbunden. Detta i hög grad beroende på den ambivalens som finns inför de internationella normer som skall reglera staters använ-dande av militärt våld.</p><p>Synen på humanitära interventioner har ändrats i överensstämmelse med de förändringar som skett inom det internationella systemet. Dessa ändringar har, till viss del, medfört en förändrad syn på de normer som legitimerar användandet av våld inom det internationella samfundet.</p><p>Humanitära interventioner som begrepp och praktik innehåller många dilemman i vår tid. Detta eftersom det berör traditionella normer av suveränitet och ickeintervention, som är de främsta byggstenarna för det moderna internationella systemet, tillika del av Förenta Na-tionernas (FN) stadgar. Stater är i dag förbjudna att använda militärt våld som ett instru-ment i deras utrikespolitik, förutom i fall av självförsvar eller i kollektiva säkerhetsåtgärder, beslutade av FN:s säkerhetsråd. Det handlar även om att det finns traditionella normer som förbjuder intervention i andra staters interna angelägenheter. Dessutom ska allt militärt våld auktorernas av säkerhetsrådet, som har till uppgift att upprätthålla internationell fred och säkerhet.</p><p>Med detta perspektiv för ögonen, är användandet av våld för att genomdriva internationella humanitära normer, mycket begränsad enligt internationell lag. Detta har i många situatio-ner skapat ett svart hål när det kommer till att stoppa allvarliga förbrytelser mot de mänsk-liga rättigheter, genom internationellt ingripande. Ovanstående har lett till att man börjat diskutera och ifrågasätta traditionella principer som har varit ledande för det internationella samarbetet, vilket i sin tur skulle kunna öppna vägen för vissa interventioner med humani-tära syften.</p><p>Denna diskussion handlar om suveränitet, internationella lag och det handlar om moraliska ställningstaganden. Realismen har under lång tid varit den ledande skolan i internationella relationer och därmed lagt grunden för hur man ska tolka internationella konflikter, krigs-föring och interventioner. På senare tid har Realismen utmanats av andra teoretiska skolor och ställningstaganden som ifrågasätter Realismens förmåga att förklara händelser på den internationella arenan.</p><p>Genom att jämföra Realismens ståndpunkter, gentemot humanitära interventioner, med Utilitarismen och den Kosmopolitiska skolan, har uppsatsen kunnat presentera olika bilder av den problematik som humanitära interventioner idag står inför och därmed måste för-hålla sig till. Igenom att granska konflikten i Rwanda 1994 och Kosovo 1999 har problema-tiken runt humanitära interventioner ytterligare kunnat belysas och diskuteras. Detta har skett genom en kvalitativ textanalys.</p><p>Nyckelord: Humanitär Intervention, Suveränitet, Icke-intervention, Internationell lag, Rea-lism, Kosmopolitanism, Utilitarism, Moral</p> / <p>Humanitarian intervention is a concept within international relations that provoke many diverse feelings and questions. Although the idée too use force in the name of ending crimes against human rights may seem attractive from a moral perspective, its practise has been highly irregular. This is much due to the norms that regulate states use of military force.</p><p>The view on humanitarian interventions has changed in unity with the changes that have appeared within the international system. These changes have, to some extent, brought on a transformation in how we look upon the norms that regulate the use of force within the international community.</p><p>Humanitarian intervention is also a concept and practises that creates many dilemmas in our time. This because it touches and concerns traditional norms of sovereignty and non-intervention, that is not only fundamental building stones for the modern international system, but also a immense part of the structure of the United Nations (UN). States today, are forbidden to use military force as an integrated part of their foreign policy, except in cases of self-defence or collective security measures authorised by the UN Security Council. It is also about customary norms, which declare that states should not interfere in other states internal affaires.</p><p>In the company of the above stated, the use of force to implement humanitarian norms is fairly limited according to international law. This has repeatedly created a gap when it comes to stop serious violations against human rights through international interference. The above stated has led to an intense discussion concerning how traditional principals may have to chance in ways that better can guide international cooperation’s in these matters. This discussion may in turn lead to an opening for some sort of interventions with humanitarian purposes.</p><p>This discussion, furthermore, concerns sovereignty, international law, and it is about morality. Realism has for a long period of time been the leading school in international relations and has laid the ground for how we should interpret international conflicts, war and intervention. Recently, this school has been forced too respond to opposition from some other theoretical schools; questioning Realisms ability to explain activities on the international arena.</p><p>By comparing Realism opinion toward humanitarian interventions, with the Utilitarian and Cosmopolitan school, this thesis has been able to present different pictures describe the complexity of humanitarian interventions. Through analyse of the conflicts taking place in Rwanda 1994 and in Kosovo 1999, the issue of humanitarian intervention has been further scrutinised and discussed. This has been done through a qualitative text analyse.</p><p>Keywords: Humanitarian Intervention, Sovereignty, Non-intervention, International law, Realism, Cosmopolitanism, Utilitarianism, Morality</p>

This work presents business process analysis methodology which consists of presentation of the business processes created on the ground of the Resource Event Agent model by means of Piece–Linear Aggregate approach. The aggregate specification is analyzing using first order predicate logic while checking correctness by resolution method using logic programming based language Prolog. The work is concluded with concrete example of analysis of Resource Event Agent model based business process using the aggregate approach. The novelty of this work PLA (Piece-Linear Aggregate) model and the software tools, created on the ground of PLA (Piece-Linear Aggregate), are used the first time for business processes analysis that is defined using REA formalism. The use of such integrated models allows performing the automated analysis of general and individual properties (completeness, deadlock freeness, termination or cyclic behavior, boundedness) of defined business processes. The main results are achieved: • The methodology, that consists of presentation of the business processes created on the ground of the Resource Event Agent model by means of Piece–Linear Aggregate approach. • Verification and validation of general and individual properties by using PLA and PROLOG language approach designed system that executes the analysis of aggregate specification. • Implementing internal accounting controls as constraints in relational algebra, SQL and PROLOG language. • Concrete...

This affirmation can be verified in the investigation to identify the rare species in Brazil and the key biodiversity areas (ACBs). In that study were identified for Brasil 2.256 rare species and 752 ACBs. The Rio Grande do Norte (RN) was the only Brazilian state that has not been identified any rare species and no ACBs, possibly due to the lack of floristic studies in this state. A particular area was selected for this study: an area of ecological tension with savanna physiognomy in Rio do Fogo, RN. This savanna community is represented in RN in a fragment and immersed in restinga and caatinga and was identified and described only through of radar imagens there are no studies to date in loco . We have prepared the following questions about this community savanna: 1) The region delimited and described by through of radar images by the RADAMBRASIL, 1976, can be associated of the Cerrado, in terms of floristic ?; 2) What is the floristic composition of this area? This area includes rare species, endemic or endangered? 3) What is the geographical and phytogeographical distribution of plant species registered in this area? 4) Those plant species registered are endemic or have affinity with other areas phytoecological Brazilian? To answer these questions we performed a floristic inventory of the August 2007 to September/2009. The results are presented in two chapters (manuscripts). The first chapter, titled "The Savannah Rio Grande do Norte: floristic links with other plant formations in the Northeast and Center-West Brazil" was submitted to the Revista Brasileira de Bot?ncia. Chapter 1 discusses the phytogeographical distribution of the species, by comparing floristic studies conducted in the Cerrado, Caatinga and Restinga in the Northeast and Cerrado of the Central Brazil. The analysis of data of this study and compilation with other studies indicated that: i) the record of 94 plant species; ii) of total species, about 64% are associated with the Cerrado, the second specialized bibliography, and about 78% as the List of Species of Flora of Brazil. However, about 73% of total species (94) are also distributed in the Caatinga, the Atlantic forest 64%, the Amazon forest 64%, the Pantanal 15% and the Pampa 12%. Floristically the data show that the community studied is influenced by other floras, has a structure where grasses dominate and also because of his appearance the same savanna then be classified as a Savana gram?neo-lenhosa do tabuleiro . Chapter 2, titled "Considerations on the flora of a savanna community in Rio Grande do Norte, northeastern Brazil: Subsidy key area for conservation" was submitted to the Revista Natureza e Conserva??o. This has the objective of improve the knowledge of flora of Rio Grande do Norte and to identify possible rare species and consequently increase the key areas of biodiversity in Brazil. The data indicated that: i) of 94 species registered in the study area, 40 were new records for the Rio Grande do Norte state; ii) These citations to unpublished state, Stylosanthes montevidensis Vogel (Fabaceae) and Aristida laevis (Nees) Kunth (Poaceae) are indicated for the first time to the Northeast of Brazil; iii) are registered in the area 24 species endemic to Brazil and 63 non-endemic; iv) Aspilia procumbens Baker (Asteraceae) registered in the area is considered a restricted species and micro endemic Rio Grande do Norte, ie rare species; v) Aspilia procumbens is also cited in the category of critically endangered species and Stilpnopappus cearensis Hubber (Asteraceae) a species vulnerable to extinction. This study shows a new area phytoecological in Rio Grande do Norte and indicates the area's potential to contribute with the sites of global significance for biodiversity conservation, either locally, regionally and nationally. This will certainly contribute to respond some targets set by the Global Strategy for Plant Conservation and the Convention on Biological Diversity such as the inventory of vegetal diversity in a region with little collection, which will provide data that contributes to questions and themes related to biodiversity. / Estudos sobre a biodiversidade brasileira s?o ainda muito escassos, sendo poss?vel observar uma grande discrep?ncia de conhecimentos entre as v?rias regi?es do pa?s. Esta afirma??o est? baseada no fato de que foram identificadas para o Brasil 2.256 esp?cies raras de plantas e 752 ?reas-chave para biodiversidade (ACBs), no entanto, o Rio Grande do Norte foi o ?nico estado brasileiro que n?o apresentou nenhuma esp?cie rara e nenhuma ?rea-chave para biodiversidade, possivelmente, devido ? escassez de levantamentos flor?sticos nesse estado. O presente estudo foi realizado em um ambiente especial: uma ?rea de tens?o ecol?gica com fisionomia sav?nica localizada no munic?pio de Rio do Fogo, RN. Essa comunidade sav?nica est? representada na forma de pequena mancha e imersa entre a Caatinga e a Restinga. Foi identificado e descrito apenas com base em imagens de radar, n?o havendo, at? o presente momento, estudos in loco. Neste contexto foram elaboradas algumas perguntas sobre essa comunidade sav?nica: 1) A regi?o delimitada e descrita por meio de imagens de radar, RADAMBRASIL de 1976, pode ser do dom?nio Cerrado, do ponto de vista flor?stico?; 2) Qual ? a composi??o flor?stica dessa ?rea? Ela inclui esp?cie rara, end?mica ou amea?ada de extin??o?; 3) Qual ? a distribui??o geogr?fica e fitogeogr?fica das esp?cies vegetais registradas nessa ?rea?; 4) As esp?cies vegetais registradas s?o end?micas ou possuem afinidade com outros dom?nios fitoecol?gicos brasileiro? Visando responder a essas indaga??es foi realizado um levantamento flor?stico, no per?odo de agosto/2007 a setembro/2009. Os resultados obtidos s?o apresentados em forma de dois cap?tulos (manuscritos). O cap?tulo 1, intitulado A Savana do Rio Grande do Norte: Rela??es flor?sticas com outras forma??es vegetais do Nordeste e Centro-Oeste Brasileiro foi submetido ? Revista Brasileira de Bot?nica. Aborda a distribui??o fitogeogr?fica das esp?cies, atrav?s da compara??o com estudos flor?sticos realizados nos cerrados, caatingas e restingas do Nordeste e cerrados do Planalto Central. As an?lises dos dados obtidos no presente trabalho e, tamb?m, atrav?s de compila??o com outros estudos apresentaram: i) o registro de 94 esp?cies vegetais; ii) desse total de esp?cies, cerca de 64 % est?o associadas ao Cerrado, segundo bibliografia especializada, e cerca de 78 % conforme a Lista de Esp?cies da Flora do Brasil. Todavia, cerca de 73 % do total das esp?cies (94) registradas tamb?m se distribuem na Caatinga, 64 % na Floresta Atl?ntica, 50 % na Floresta Amaz?nica, 15 % no Pantanal e 12 % no Pampa. Floristicamente os dados apontaram que comunidade estudada recebe influ?ncia de outras floras, possui uma estrutura onde as gram?neas dominam e tamb?m devido a sua fisionomia sav?nica a mesma, ent?o, poder ser classificada como Savana gram?neo-lenhosa do tabuleiro. O cap?tulo 2, intitulado Considera??es sobre a flor?stica de uma comunidade sav?nica no Rio Grande do Norte, Nordeste do Brasil: Subs?dio de ?rea-chave para a conserva??o foi submetido ? Revista Natureza e Conserva??o. Teve como objetivo contribuir para melhorar o conhecimento sobre a flora do Rio Grande do Norte, identificando poss?veis esp?cies raras e, assim, expandir as ?reas-chave de biodiversidade no Brasil. Os dados obtidos indicaram que: i) das 94 esp?cies encontradas na ?rea de estudo, 39 foram registradas pela primeira vez para o Rio Grande do Norte; ii) dessas cita??es in?ditas para o estado, as esp?cies Stylosanthes montevidensis Vogel (Fabaceae) e Aristida laevis (Nees) Kunth (Poaceae) s?o indicadas, tamb?m, pela primeira vez para a Regi?o Nordeste do Brasil; iii) ocorrem na ?rea 24 esp?cies end?micas do Brasil; iv) Aspilia procumbens Baker (Asteraceae) registrada na ?rea ? considerada uma esp?cie restrita e microend?mica do Rio Grande do Norte, ou seja, esp?cie rara; v) Aspilia procumbens ? tamb?m apontada na categoria das esp?cies criticamente em perigo e Stilpnopappus cearensis Hubber (Asteraceae) uma esp?cie vulner?vel a extin??o. O presente estudo aponta um novo dom?nio citoecol?gico para o Rio Grande do Norte e apresenta o potencial da ?rea em contribuir com os s?tios de signific?ncia global para conserva??o de biodiversidade, seja no ?mbito local, regional e nacional. Isso contribuir? para responder alguns dos objetivos fixados pela Estrat?gia Global para a Conserva??o de Plantas e da Conven??o sobre Diversidade Biol?gica, tal como, o invent?rio da diversidade vegetal, em uma regi?o com pouca coleta, que fornecer? dados que contribuem para quest?es e temas relativos ? biodiversidade.

In this sense, this research aimed to emphasize the use of environmental perception of social agents are significant elements for the understanding of the man / nature, and develop educational activities aimed at raising awareness and changing attitudes towards environmental issues thus promoting reflections on Environmental Education (EE) as a critical and transformative tool for conservation of rich biological diversity. This research covers as a place of study, schools located in the Environmental Protection Area Jenipabu (APAJ), Rio Grande do Norte. Methodology in general, we highlight the use of questionnaires and mind maps as generators of the contents of empirical research, and execution of content analysis for the treatment of data collected. This dissertation has two chapters in the form of scientific articles, where the first is entitled: "Study of the perceptions and evaluation of interactions concerning environmental education in schools in a conservation area of Rio Grande do Norte - Brazil", obtaining thus a primary diagnosis for analysis about the visions that students and teachers from two schools located in APAJ have on the environment. The second article, entitled: "Effective and analysis of educational activities that promote biodiversity in a coastal area of Environmental Protection Northeast - Brazil" provides an analysis of the educational use of biodiversity as a way to raise awareness of the need for environmental conservation. It appears from research that there is a lack of training in EA by teachers, but there is a need for greater involvement of students in conservation areas, however, from the analysis of educational activities, we observed that the effectiveness of such actions acts to promote awareness and change in actors involved. Thus, environmental education needs to take into account the different perceptions found in each individual, and it can not be based solely on transmission of knowledge, so that we reach a model of conservation. / Temas importantes envolvendo o despertar para a necessidade de conserva??o da biodiversidade e da import?ncia de se criar Unidades de Conserva??o, como estrat?gia em busca da defesa do meio ambiente, est?o cada vez mais sendo desenvolvidos em campos investigativos biol?gicos e sociais. Nesse sentido, objetivou-se nessa pesquisa, enfatizar o uso da percep??o ambiental dos agentes sociais sendo elementos significativos para o entendimento da rela??o homem/natureza, e desenvolver a??es educacionais voltadas para sensibiliza??o e mudan?a de atitudes frente ?s quest?es ambientais para assim, promover reflex?es sobre a Educa??o Ambiental (EA) cr?tica e transformadora como um rico instrumento de conserva??o da diversidade biol?gica. Esta pesquisa abrange como local de estudo, escolas situadas na ?rea de Prote??o Ambiental Jenipabu (APAJ), Rio Grande do Norte. Na Metodologia Geral, destacam-se a utiliza??o de question?rios e mapas mentais como geradores dos conte?dos emp?ricos da pesquisa, e efetiva??o da an?lise de conte?do para o tratamento dos dados coletados. Esta disserta??o conta com dois cap?tulos em formato de artigos cient?ficos, onde o primeiro intitula-se: Estudo das percep??es e avalia??o de intera??es educativas voltadas ao meio ambiente em escolas de uma Unidade de Conserva??o do Rio Grande do Norte Brasil , obtendo, assim, um diagn?stico primordial para an?lise acerca das vis?es que alunos e professores de duas escolas situadas na APAJ t?m sobre o meio ambiente. O segundo artigo, cujo t?tulo ?: Efetiva??o e an?lise de a??es educativas promotoras da biodiversidade em uma ?rea de Prote??o Ambiental costeira do Nordeste Brasil traz uma an?lise sobre a utiliza??o de a??es educativas sobre a biodiversidade como forma de sensibiliza??o para a necessidade de conserva??o ambiental. Infere-se da pesquisa que h? car?ncia na forma??o em EA por parte dos professores, como tamb?m h? necessidade de um envolvimento maior dos alunos com a Unidade de Conserva??o Por?m, a partir da an?lise das a??es educativas realizadas, observamos que a efetiva??o de tais a??es atua promovendo sensibiliza??o e transforma??o nos sujeitos envolvidos. Sendo assim, a Educa??o Ambiental precisa levar em considera??o as diversas percep??es encontradas em cada indiv?duo, e que n?o pode ser pautada apenas na transmiss?o de conhecimentos, para que assim, alcancemos um verdadeiro modelo de conserva??o.

The piles were tested in two different areas at the same site. Both areas consisted of a 3-m thick compacted superficial fill of pure fine sand, underlain by layers of naturally occurring pure fine-thick sand. Fills are differentiated by the relative densities which were compressed, 45% e 70%, respectively. Each area received one identical pair of cfa piles and two identical pairs of H-piles. A static lateral loading test was performed in each pair of piles. In this work, the pile load test results are reported and interpreted. The horizontal coefficient of subgrade reaction was determined from the results of the loading tests and compared with values determined by correlations based on penetration resistance index of SPT tests (NSPT). p-y formulations describing the static behavior of the piles were applied to the problem under evaluation. Back Analyses were made through theoretical and experimental p-y curves for obtaining input parameters for the analytic models, among which the coefficient of horizontal reaction. The soil pile system horizontal loading at rupture was determined by the theoretical methods and the results were compared with the experimental results, checking its validity / Um estudo experimental foi realizado para investigar o comportamento de estacas escavadas h?lice cont?nua e estacas cravadas met?licas submetidas a carregamentos laterais em areia. As estacas foram ensaiadas em duas ?reas diferentes no mesmo local. Ambas as ?reas eram compostas por um aterro superficial de 3 m de espessura de areia fina, seguido de camadas naturais de areia fina a grossa. Os aterros diferenciam-se pela densidade relativa com que foram compactados, 45% e 70%, respectivamente. Cada ?rea recebeu um par id?ntico de estacas h?lice cont?nua e dois pares id?nticos de estacas met?licas com perfil H . Em cada par de estacas foi executada uma prova de carga est?tica. Neste trabalho, os resultados das provas de carga s?o apresentados e interpretados. O coeficiente de rea??o horizontal do solo foi determinado atrav?s dos resultados das provas de carga e comparado com valores obtidos a partir de correla??es baseadas no ?ndice de resist?ncia ? penetra??o do ensaio SPT (NSPT). Curvas p-y foram constru?das para prever o comportamento de estacas submetidas a carregamentos horizontais. Retro an?lises foram efetuadas atrav?s das curvas p-y te?ricas e experimentais para obten??o de par?metros de entrada para os modelos anal?ticos, dentre os quais o coeficiente de rea??o horizontal. A carga de ruptura do sistema solo estaca foi determinada atrav?s de m?todos te?ricos e os resultados foram comparados com os resultados experimentais, verificando sua validade

The RAA has aroused attention in the context of Civil Engineering from the early 80, when they were reported consequences of his swelling effect in concrete structures, including cracking, failure and loss of serviceability. Despite the availability of experimental results the problem formulation still lacks refinement so that your solution remains doubtful. The numerical simulation is important resource for the assessment of damages in structures caused by the reaction, and their recoveries The tasks of support of this work were performed by means of the finite element approach, about orthotropic non-linear formulation, and, thermodynamic model of deformation by RAA. The results obtained revealed that the swelling effect of RAA induced decline of the mechanical performance of concrete by decreasing the margin of safety prior to the material failure. They showed that the temperature influences, exclusively, the kinetics of the reaction, so that the failure was the more precocious the higher the temperature of the solid mass of concrete / O objetivo deste trabalho ? a simula??o num?rica do desempenho Mec?nico de membros de concreto afetados pela Rea??o ?lcali-Agregado ou RAA, reportada por Stanton em 1940. A RAA despertou a aten??o no ?mbito da Engenharia Civil a partir da d?cada de 80, quando foram relatadas consequ?ncias de seu efeito expansivo em estruturas de concreto, incluindo fissura??o, ru?na e perda de funcionalidade. Apesar da disponibilidade de resultados experimentais a formula??o do problema ainda carece de aperfei?oamento de modo que sua solu??o permanece duvidosa. A simula??o num?rica ? recurso importante para a avalia??o de danos em estruturas provocados pela rea??o, e suas recupera??es. As tarefas de suporte desse trabalho foram realizadas mediante a aproxima??o por elementos finitos, sobre formula??o ortotr?pica n?o linear, e, modelo termodin?mico de deforma??es por RAA. Os resultados obtidos revelaram que o efeito expansivo da RAA induziu o decl?nio do desempenho mec?nico do concreto diminuindo a margem de seguran?a pr?via ? ru?na do material. Ficou evidente que a temperatura influencia, exclusivamente, a cin?tica da rea??o, de modo que a ru?na foi tanto mais precoce quanto maior a temperatura da massa s?lida do concreto

Pesquisa do estado de Minas Gerais (FAPEMIG) / O objetivo do trabalho foi avaliar o efeito do uso de composto org?nico de ind?stria de fia??o e tecelagem sobre a qualidade do substrato e crescimento de esp?cies arb?reas do cerrado em uma cascalheira no munic?pio de Diamantina, MG. A disserta??o foi estruturada em quatro cap?tulos. O primeiro refere-se ? revis?o bibliogr?fica visando o entendimento dos conceitos que foram abordados no estudo. No segundo capitulo, a influ?ncia do composto no substrato foi avaliada por meio das altera??es nos atributos qu?micos (pH, mat?ria org?nica (MO), soma de bases (SB), CTC, satura??o por bases (V), f?sforo (P), pot?ssio (K), c?lcio (Ca2+), magn?sio (Mg2+), acidez troc?vel (Al3+), acidez potencial (H + Al) e satura??o por alum?nio (m)) e f?sicos (resist?ncia mec?nica a penetra??o (Rp) e granulometria) do substrato. Foi avaliada tamb?m a atividade microbiana: carbono da biomassa microbiana (CBM) respira??o microbiana (C-CO2) e quociente metab?lico (qCO2) ap?s aplica??o de cinco tratamentos: sem aplica??o de composto org?nico e diferentes concentra??es 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova. O delineamento foi sistem?tico tipo ?leque? sendo os tratamentos dispostos em tr?s blocos casualizados. A adi??o do composto proporcionou o aumento nos valores de pH, MO, SB, CTC, V e nutrientes (P, K, Ca2+ e Mg2+) e promoveu a redu??o de Al3+, H + Al e m. O substrato minerado apresentou valores elevados de Rp indicando a compacta??o na ?rea degradada pela extra??o de cascalho, mesmo ap?s a aplica??o do composto. A adi??o de doses crescentes do composto promoveu o aumento significativo de CBM e C-CO2 ao substrato minerado. O maior valor de qCO2 indicou efici?ncia da biomassa microbiana com a incorpora??o das menores doses do composto ao substrato quando comparado ao controle. O terceiro cap?tulo refere-se ao estudo do crescimento das esp?cies nativas Kielmeyera lathrophyton Saddi (Pau santo), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacarand? do cerrado) e Bowdichia virgilioides Kunth (Sucupira-preta) plantadas em delineamento sistem?tico tipo ?leque? submetidas a cinco tratamentos: sem aplica??o de composto org?nico e diferentes doses de composto 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova dispostos em tr?s blocos casualizados. Ap?s 12 meses, verificou-se que n?o houve diferen?a significativa entre os tratamentos para sobreviv?ncia e incremento em altura, di?metro e cobertura de copa para cada esp?cie. Ainda, de forma preliminar foi poss?vel determinar que a adi??o de 4,5 g dm-3 de composto na cova proporcionou maiores valores de incremento em altura, di?metro e cobertura de copa para Plathymenia reticulata e Bowdichia virgilioides. No quarto cap?tulo, foi realizado o plantio em linha de Chamaecrista debilis submetida a quatro tratamentos, 0,0; 30,0; 60,0 e 120,0 g dm-3 de composto como adubo por cova, dispostos em tr?s blocos casualizados. Os resultados indicaram que n?o houve diferen?a significativa entre as doses de composto aplicado para incremento em altura, di?metro e cobertura de copa. O maior valor de incremento em altura e cobertura de copa ocorreu sem a adi??o de composto de res?duo org?nico de ind?stria de fia??o e tecelagem e para di?metro com a aplica??o de 60,0 g dm-3, no entanto, ? necess?ria a realiza??o de avalia??es futuras. A taxa de sobreviv?ncia apresentou decr?scimo significativo com a aplica??o das maiores dosagens de composto org?nico. A esp?cie Chamaecrista debilis apresentou caracter?sticas importantes para recupera??o de ?rea degradada, como r?pido crescimento e produ??o de biomassa. / Disserta??o (Mestrado) ?

The dissertation was structured in four chapters. Being the first, regarding the bibliographical revision seeking the understanding of the concepts and theoretical questions of what was borded in the study. In the second I chapter, the influence of the compound in the substratum was evaluated through the alterations in the chemical attributes (pH, organic matter (MO), sum of bases (SB), CTC, saturation for bases (V), match (P), potassium (K), calcium (Ca2+), magnesium (Mg2+), exchangeable acidity (Al3+), potential acidity (H + Al) and saturation for aluminum (m)) and physical (mechanical resistance the penetration (Rp) and texture) of the substratum. As well as in the microbial activity of the same: carbon of the microbial biomass (CBM) microbial breathing (C-CO2) and metabolic quotient (qCO2) after application of five treatments: without application of organic composition and different concentrations 0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole. The delineation was systematic type "fan" being the treatments disposed in three blocks unexpected. The addition of the compound stimulated the increase in the pH values, MO, SB, CTC, V and nutritious (P, K, Ca2+ and Mg2+) and it promoted the reduction of Al3+, H + Al and m. The mined substratum presented high values of Rp indicating the compactation in the area degraded by the gravel extraction, even after the application of the composed. The addition of growing doses of the compound promoted the significant increase of CBM and C-CO2 to the mined substratum. The largest qCO2 value indicated efficiency of the microbial biomass with the incorporation of the smallest dosages of the compound to the substratum when compared to the control. The third chapter, refers to the study of the growth of the native species Kielmeyera lathrophyton Saddi (sacred Wood), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacaranda of the Thicket) and Bowdichia virgilioides Kunth (Sucupira-black) planted in delineation systematic type " fan " submitted to five treatments: without application of organic composition and different doses of compound 0,0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole disposed in three blocks unexpected. After 12 months, it was verified that there was not significant difference among the treatments for survival and increment in height, diameter and top covering for each species. Still, in a preliminary way it was possible to determine that the addition of 45 g dm-3 of compound of organic residue of textile industry in the hole stimulated larger increment values in height, diameter and top covering for Plathymenia reticulata and Bowdichia virgilioides. In the fourth chapter, the planting was made in line of Chamaecrista debilis submitted to four treatments, 0,0; 30,0; 60,0 and 120,0 g dm-3 compound dm-3 as fertilizer for hole, disposed in three blocks inexpected. The results indicated that there was not significant difference among compound applied for increment in height and diameter. The largest increment value in height and diameter happened without the addition and with the application of 60,0 g dm-3 of compound of organic residue of textile industry, however it is necessary the accomplishment of future evaluations. The survival rate presented significant decrease with the application of the largest doses of organic compund. The species Chamaecrista debilis presented important characteristics for recovery of degraded area, as fast growth and biomass production.

Para isto, foi realizada a s?ntese do pept?deo HSP-1 propargilado ([PAG1]HSP-1) atrav?s da metodologia de s?ntese de pept?deo em fase s?lida (SPFS) via estrat?gia Fmoc. Ap?s a confirma??o da obten??o do [PAG1]HSP-1 por espectrometria de massa (MALDI-ToF), foi realizada a glicosila??o com as inser??es dos derivados azido acetilado de glicose e N-acetilglicosamina na presen?a de sulfato de cobre penta hidratado (CuSO4.5H2O) e de ascorbato de s?dio como agente redutor para obten??o dos glicopept?deo-triaz?is [Glc-trz-G14]HSP-1 e [GlcNAc-trz-G14]HSP-1. Os produtos das s?nteses foram purificados por cromatografia l?quida de alta efici?ncia de fase reversa (CLAE-FR) e tamb?m caracterizados por espectrometria de massa (MALDI-ToF), confirmando a forma??o regiosseletiva dos glicopept?deo-triaz?is sem produ??o de subprodutos da glicosila??o. Os estudos biol?gicos comparativos entre o pept?deo HSP-1 e de suas formas glicosiladas revelaram que as modifica??es qu?micas n?o alteraram significativamente a efic?cia do HSP-1 contra agentes bacterianos. Entretanto, os testes antif?ngicos demonstraram melhor atividade fungicida para os glicopept?deos quando comparado ao pept?deo HSP-1. Foram ainda realizados estudos conformacionais e de intera??o entre o pept?deo e os glicopept?deos com ves?culas fosfolip?dicas de car?ter zwitteri?nico (POPC) e ani?nico (POPC/POPG). Os estudos conformacionais empregando-se a t?cnica de Dicro?smo Circular (CD) revelaram menor teor de helicidade tanto em LUV?s de POPC quanto de POPC/POPG para os glicopept?deos em rela??o a HSP-1. Os estudos de intera??o foram realizados empregando-se as t?cnicas de espalhamento de luz din?mico (DLS), potencial zeta (?) e extravasamento de carboxifluoresce?na (CF). De uma maneira geral, verifica-se que a varia??o no di?metro hidrodin?mico (?Dh) para ves?culas ii zwitteri?nicas POPC e ani?nicas POPC/POPG ? maior para os glicopept?deos [Glc-trz-G14]HSP-1e [GlcNAc-trz-G14]HSP-1 em rela??o ao HSP-1. Por outro lado, a varia??o do potencial zeta tanto em ves?culas zwitteri?nicas quanto em ves?culas predominantemente negativas causada por HSP-1 foi maior em compara??o ao efeito causado pelas formas glicosiladas. E por fim, os resultados de extravasamento de carboxifluoresce?na induzida por cada esp?cie (HSP-1, [Glc-trz-G14]HSP-1 e [GlcNAc-trz-G14]HSP-1) mostrou que a capacidade l?tica dos glicopept?deos ? ligeiramente maior em ambos os meios biomim?ticos quando comparados com o pept?deo HSP-1. Assim sendo, este trabalho mostrou que a presen?a do anel triaz?lico pode ser respons?vel pela maior atividade antif?ngica dos glicopept?deos [Glc-trz-G14]HSP-1 e [GlcNAc-trz-G14]HSP-1 em rela??o ao pept?deo HSP-1. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Qu?mica, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2015. / ABSTRACT This work proposes the glycosylation of the antimicrobial peptide HSP-1, containing 14 amino acid residues and originally isolated from Hyla punctata species (PRATES et al., 2004) by solid phase peptides synthesis associated with cycloaddition reaction copper catalyzed (SHARPLESS et al., 2002). The synthesis of propargylated HSP-1 ([PAG1] HSP-1) was carried out by solid phase peptide synthesis using Fmoc strategy and characterized by mass spectrometry (MALDI-ToF). In order to obtain the glycopeptide triazoles [Glc-trz-G14]HSP-1 and [GlcNAc-trz-G14]HSP-1, azide derivatives acetylated glucose and N-acetylglucosamine were used in the presence of copper sulfate pentahydrate (CuSO4. 5H2O) and sodium ascorbate as a reducing agent. The products were purified by reverse phase high performance liquid chromatography (RP-HPLC) and characterized by mass spectrometry (MALDI-ToF), confirming the regioselective reaction without glycosylation secondary products. Comparative studies among HSP-1 peptide and their glycosylated forms don?t show significant changes in antibacterial assays. However, the antifungal tests have shown a significant increase in fungicidal activity for glycopeptides when compared to HSP-1 peptide. Furthermore, it were carried out conformational and interaction studies among the peptide and glycopeptides with zwitterionic (POPC) and anionic (POPC/POPG) phospholipid vesicles. The circular dichroism (CD) spectra have revealed lower helicity to glycopeptides relative HSP-1 in both zwitterionic and anionic LUV's. Interaction studies were performed employing the dynamic light scattering (DLS), zeta potential and leakage carboxyfluorescein (CF) techniques. Summing up, the hydrodynamic diameter variation (?Dh) for zwitterionic and anionic vesicles is greater for glycopeptides [Glc-trz-G14]HSP-1 and [GlcNAc-trz-G14]HSP-1 when compared with HSP-1. On the other hand, the zeta potential variation in zwitterionic or negative vesicles caused by HSP-1 was higher compared to the effect caused by glycosylated forms. Finally, the results of carboxyfluorescein leakage induced by each species (HSP- iv 1 [Glc-trz-G14] HSP-1 and [GlcNAc-trz-G14] HSP-1) showed a higher lytic capacity of glycopeptides in both media in relation to the HSP-1 peptide. Thus, it showed that the presence of triazole rings may be responsible for the higher antifungal activity of derivatives [Glc-trz-G14] HSP-1 and [GlcNAc trz-G14] HSP-1.
