Estas vibra??es s?o em sua maioria compostas de ondas Rayleigh e s?o mais fortes na faixa de frequ?ncia de 0.04 ? 1 Hz. Seus mecanismos de gera??es ainda s?o quest?es de debates, mas ? consenso que eles est?o relacionados com perturba??es atmosf?ricas e ondas oce?nicas de gravidade. O Arquip?lago de S?o Pedro e S?o Paulo (ASPSP) est? localizado na regi?o equatorial do Oceano Atl?ntico cerca de 1.100 km de dist?ncia da costa do nordeste brasileiro. O ASPSP ? composto por um conjunto de v?rias pequenas forma??es rochosas com uma ?rea total de aproximadamente 17.000 m?. Devido a sua localiza??o distante do continente, isolamento e aus?ncia de ru?dos provocados pela atividade humana, este local ? ideal para a medi??o de ru?do micross?smico e investiga??o de sua rela??o com algumas vari?veis clim?ticas e oceanogr?ficas. No ASPSP registramos microssismos prim?rios (PM) entre 0.04 - 0.12 Hz e microssismos secund?rios (SM) entre 0.12 - 0.4 Hz durante 10 meses em 2012 e 2013. As an?lises indicam uma boa correla??o entre o ru?do micross?smico na regi?o e uma depend?ncia do clima de ondas. Em particular, com inverno no hemisf?rio norte. Tamb?m ? mostrado que a maior parte do PM ? gerado no pr?prio ASPSP. O local de gera??o do SM depende do comportamento das vari?veis clim?ticas e oceanogr?ficas no hemisf?rio norte. / Microseisms are continuous vibrations pervasively recorded in the mili Hertz to 1 Hz frequency range. These vibrations are mostly composed of Rayleigh waves and are strongest in the 0.04 to 1 Hz frequency band. Their precise source mechanisms are still a matter of debate but it is agreed that they are related to atmospheric perturbations and ocean gravity waves. The Saint Peter Saint Paul Archipelago (SPSPA) is located in the equatorial region of the Atlantic Ocean about 1,100 km distant from the Brazilian northeastern coast. The SPSPA is composed by a set of several small rocky formations with a total area of approximately 17,000 m?. Due to its remote distance from the continent and the lack of cultural noise, this location is a unique location for measuring microseismic noise and to investigate its relation with some climate and oceanographic variables. In the SPSPA we have recorded both primary microseisms (PM) at 0.04 ? 0.12 Hz and the secondary microseisms (SM) at 0.12 ? 0.4 Hz during 10 months in 2012 and 2013. Our analysis indicates a good correlation between the microseismic noise in the region and a seasonal dependency. In particular, the winter in the northern hemisphere. We have also shown that most of the PM is generated in the SPSPA itself. The SM source location depends with the seasonal climatic and oceanographic variables in the northern hemisphere

Em linhas gerais, objetivamos identificar fatores sem?ntico-cognitivos e discursivo-pragm?ticos implicados no uso de sufixos graduadores nominais e contribuir para o estudo do grau em aulas de L?ngua Portuguesa da Educa??o B?sica. A perspectiva te?rica que fundamenta nossa pesquisa ? a da Lingu?stica Funcional Centrada no Uso, conforme concebida por pesquisadores do grupo Discurso & Gram?tica (FURTADO DA CUNHA, BISPO, SILVA, 2013; MARTELOTTA, 2011). Segundo essa vertente te?rica, os usos lingu?sticos modelam a forma da gram?tica de uma l?ngua ao mesmo tempo em que s?o contingenciados por ela. Nesse sentido, discurso e gram?tica influenciam-se mutuamente. Em termos metodol?gicos, fazemos uma pesquisa de cunho eminentemente qualitativo com suporte quantitativo como evid?ncia de tend?ncia de uso. Caracteriza-se ainda pelo vi?s descritivo e interpretativista do fen?meno sob estudo. Os dados emp?ricos de nossa an?lise prov?m de um corpus constitu?do de textos escritos extra?dos da revista Veja, edi??es de janeiro a junho de 2011, particularmente das se??es Carta do Leitor e Gente, esta ?ltima representante da Coluna Social da revista. Os resultados de nossa an?lise mostram que os usos dos sufixos graduadores nominais est?o relacionados a fatores sem?ntico-cognitivos (constru??o de determinados sentidos do texto, associa??o a aspectos mais ancorados na experi?ncia concreta ou a sentidos mais abstratos, por exemplo), a quest?es discursivo-pragm?ticas (alcance de determinados prop?sitos comunicativos, como criticar, julgar, ironizar, reivindicar, envolvendo o leitor, buscando-lhe a ades?o a determinado ponto de vista). Al?m disso, verificamos que os usos desses elementos m?rficos nos g?neros textuais da amostra analisada relacionavam-se ? subjetividade do redator e a quest?es intersubjetivas, envolvendo escrevente e leitor, conforme Traugott e Dasher (2005). Por fim, contemplamos discuss?o acerca da abordagem de nosso objeto de estudo em aulas de L?ngua Portuguesa na Educa??o B?sica. / We study the use of nominal suffixes of degree, such as -inho, -?o, -?ssimo, -?limo, -?rrimo in written texts in Brazilian Portuguese, by focusing on semantic, cognitive, pragmatic and discourse aspects involved in using these suffixes. In general, we aim to identify semanticcognitive and discourse-pragmatic factors that motivate the usage of nominal suffixes of degree and to contribute for the study of degree in Portuguese class in Basic Education. The theoretical perspective underlying our research is the Lingu?stica Funcional Centrada no Uso, as conceived by group of researchers of Discurso & Gram?tica (FURTADO DA CUNHA, BISPO, SILVA, 2013; MARTELOTTA, 2011). According to this theoretical model, language model uses the shape of the grammar of a language at the same time they are provisioned for it. In this sense, speech and grammar influence each other. In terms of methodology, we make an eminently qualitative research with quantitative support as evidence of use of trend. It is characterized also by descriptive and interpretive bias of the phenomenon under study. Empirical evidence from our analysis come from a corpus consisting of written texts from Veja magazine, January to June 2011 issues, particularly Carta do Leitor e Gente sections, the latter representative of the Coluna Social magazine. The results of our analysis showed that the use of nominal graders suffixes are related to semantic-cognitive factors (construction of certain text directions, the association more grounded aspects of concrete experience or the more abstract meanings, for example), the discourse-pragmatic issues (range certain communicative purposes, as critique, judge, mock, claim, involving the reader, seeking her membership of a particular point of view). In addition, we found that the use of these morphic elements in genres of the sample analyzed were related to the subjectivity of the writer and the inter-subjective issues involving writer and reader, as Traugott and Dasher (2002). Finally, we contemplate discussion about the approach of our object of study in Portuguese classes in Basic Education.

Todavia, sua aplica??o para ambos os fins depende da correta interpreta??o dos dados coletados e portanto de conhecimentos pr?vios sobre o comportamento e o repert?rio ac?stico da(s) esp?cie(s) alvo(s). O sul do Brasil ? uma importante ?rea de reprodu??o para baleias francas austrais (Eubalaena australis). Esta esp?cie amea?ada agrega-se anualmente entre Julho e Novembro principalmente no estado de Santa Catarina. Medidas de prote??o s?o necess?rias para assegurar a recupera??o e para mitigar os efeitos de atividades antr?picas sobre esta popula??o. Visando construir conhecimento necess?rio para implementa??o de MAP como ferramenta de pesquisa e conserva??o da baleia franca no Brasil, o objetivo deste trabalho ? reunir informa??es sobre a ecologia ac?stica de pares-m?e filhote da esp?cie. Sensores aut?nomos foram instalados em duas localidades na APA Baleia Franca e continuamente monitoraram o ambiente e vocaliza??es de baleias francas. 1427 chamados com SNR > 10dB foram classificados em 7 categorias: upcall (55.8%), downcall (12.9%), v-call (12.3%), tonal constante (10.1%), tonal vari?vel (6.7%), h?brido (1.6%), pulsado (0.6%). A frequ?ncia de pico m?dia de todas as vocaliza??es foi 107.5?35.2 Hz e a dura??o m?dia foi de 0.8? 0.7s. A an?lise do padr?o nictemeral do comportamento vocal mostrou que o raking m?dio das taxas ajustadas de vocaliza??o em cada per?odo (amanhecer, dia, noite e anoitecer) n?o variam significativamente (Kruskal-Wallis x2=5.86, df=3, p=0.12). Provavelmente, estes resultados est?o relacionados a ontogenia comportamental dos pares e refletem a rela??o espacial entre m?es e seus respectivos filhotes no per?odo final de perman?ncia na ?rea de invernagem. Grava??es realizadas com um arranjo linear de hidrofones sincronicamente a observa??es comportamentais, revelaram que a taxa de emiss?o de chamados est? relacionada ao n?vel de atividade em cada estado comportamental. Em estados de maior atividade, como durante intera??es entre pares e entre m?es e seus filhotes, a taxa de emiss?o de chamados foi respectivamente 3.35 e 0.21 chamados/minuto. Por outro lado, enquanto se deslocando ou em descanso, a taxa de vocaliza??o foi de 0.12 e 0.02 chamados/minuto. Nenhuma vocaliza??o foi atribu?da aos pares focais em mergulho ou amamentando. Os testes exato de Fisher (F=14.82; p=0.21) e chi-quadrado (x2=19.06; df=15; p=0.37) revelaram que a associa??o entre os tipos de chamados e os estados comportamentais n?o ? significativa. Por?m classes de chamados distintas foram emitidas em propor??es diferentes em cada estado comportamental. O significado funcional das classes de vocaliza??o no contexto da comunica??o de pares f?mea-filhote ? semelhante a aquele descrito em estudos pr?vios, realizados com outros tipos de grupo da esp?cie. A composi??o de informa??es gerada por este trabalho constitui as bases do conhecimento acerca da bioac?stica da baleia franca no Brasil e ser?o fundamentais para a implementa??o de ferramentas de monitoramento e preserva??o baseadas em princ?pios ac?sticos. Al?m disso, representam um importante passo para a expans?o do conhecimento do comportamento vocal de pares m?o-filhote, um subgrupo vulner?vel por?m vital para as popula??es. / Remote acoustic sensing has been used to investigate several aspects of cetacean ecology and behaviour as occurrence, population density and impacts of anthropogenic sounds on communication systems. Nonetheless, the efficiency of PAM methods depends on the ability of researchers to detect and interpret acoustic signals and therefore on baseline information about natural features of the target species?vocal behaviour. The coastal waters off the state of Santa Catarina, Brazil, are an important wintering ground for Southern right whales (Eubalaena australis). Right whales aggregates in this area year after year, between July and November and protection measures are due to ensure the safety and health of this population. Aiming to build the required knowledge to use PAM as a right whale conservation and research tool in Brazil, the objective of the present study is to gather information concerning the acoustic ecology of right whale mother-calf pairs off Santa Catarina. Bottom-mounted archival acoustic recorders were deployed in two locations at the Right Whale APA during the wintering season. 1427 right whale calls with SNR? were classified in 7 call classes accordingly to visual and aural characteristics: upcall (55.8%), downcall (12.9%), down-up call (12.3%), tonal constant (10.1%), tonal variable (6.7%), hybrid (1.6%)and pulsive (0.6%). Mean values of start, end, maximum and minimum frequencies, frequency bandwidth, peak frequency and duration were calculated. Temporal pattern analysis revealed no significant diel trend in the emission of contact calls (Kruskal-Wallis test chi-square=5.86, df=3, P=0.12). Results may be linked to the predominant behavioral of whale groups through the period of stay at the wintering area. Using synched surface-behavioral observations and acoustic recordings, calling rates were obtained and the use of call classes in different behavioral states was discussed. Callingrates (call/min) were associated with the activity level of mo/ca pairs, greater in interactions and bonding and lower during travelling and resting. No calls were attributed to diving or nursing pairs. Upcalls and down-upcalls calls were attributed to resting pairs as well as traveling pairs. Constant calls were detected when a pair was swimming toward the research boat and pulsive calls were detected in the presence of dolphins in close proximity to the dislocating focal group. Interestingly, mo/ca pairs spend 20% of the sampling time interacting with other pairs and the greatest diversity of calls was recorded during such events. Pulsive (12%) and hybrid calls (13%-exclusively recorded during mo/ca interactions) are characteristics of agonistic behavior between whales. When bonding, mother and/or calves produced exclusively upcalls.The adaptative significance of previously described calls in mother-calf pair ?s communication is similar to what has been described for other whale groups.This dissertation brings significant information that constitutes bases of right whale bioacoustics in Brazil, and therefore will be vital for the implementation of mitigation, monitoring and investigation tools based on acoustic principles. Moreover, it contributed to fulfil the lack of behavioural and acoustic data of mother-calf pairs a highly vulnerable and vital subgroup for all right whale populations.

Em linhas gerais, objetivamos investigar o uso das relativas em perspectiva hist?rica no PB, focalizando motiva??es cognitivas e interacionais implicadas e a correla??o com as tradi??es discursivas. A perspectiva te?rica que fundamenta o nosso estudo ? a da Lingu?stica Funcional de vertente norte-americana, inspirada em Talmy Giv?n, Sandra Thompson, Paul Hopper, Joan Bybee, Elizabeth Traugott, M?rio Martelotta, Ang?lica Furtado da Cunha, entre outros, conjugada a contribui??es das Tradi??es Discursivas, com base em autores como Kabatek, Koch e Oesterreicher. Quanto ? metodologia, a nossa pesquisa ? eminentemente qualitativa, no sentido de que busca elucidar motiva??es discursivo-pragm?ticas e cognitivas relacionadas ao uso das estrat?gias de relativiza??o no PB; e tem suporte quantitativo, no que se refere ao aspecto mensur?vel dos dados e caracteriza??o do objeto de estudo e sua frequ?ncia de uso. Para esta investiga??o, utilizamo-nos dos corpora do projeto Para a Hist?ria do Portugu?s Brasileiro (PHPB), de modo mais espec?fico, das cartas particulares, oficiais, de leitor e de redator escritas entre os s?culos XVIII e XX, de quatro estados: Minas Gerais, Paran?, Pernambuco e Rio de Janeiro. Os resultados desta pesquisa revelam a varia??o no dom?nio da relativiza??o, tendo em vista o aumento do percentual de relativas cortadoras no corpus desta investiga??o, ainda que a ocorr?ncia dessa estrat?gia esteja mais restrita ?s cartas particulares. Al?m disso, verificamos fatores de natureza cognitiva como redu??o do custo cognitivo e economia relacionados ? ocorr?ncia da relativa cortadora, principalmente, nas cartas particulares; aspectos como a necessidade de expressividade e clareza relacionados ao uso, mesmo que pouco frequente, da copiadora, principalmente nas cartas oficiais; e fatores de ordem comunicativa como a esfera p?blica de circula??o de parte das cartas da amostra, como nas cartas de redator e do leitor, e o distanciamento entre os interlocutores implicados mais diretamente no uso das relativas padr?o da nossa amostra. / In this study, we focus on the relativization strategies, in diachronic corpus of Brazilian Portuguese (BP). Generally speaking, we aim to investigate the use of the relative in a historical perspective on BP, focusing on semantic-cognitive and discursive-pragmatic motivations involved and the correlation with the discursive traditions. The theoretical perspective underlying our study is the North-American Functional Linguistics, inspired by Talmy Giv?n, Sandra Thompson, Paul Hopper, Joan Bybee, Elizabeth Traugott, Mario Martelotta, Angelica Furtado da Cunha, among others, combined with contributions of Discursive Traditions, based on authors such as Kabatek, Koch and Oesterreicher. As for the methodology, our research is eminently qualitative, in the sense that it seeks to elucidate semantic-cognitive and discursive-pragmatic motivations related to the use of relativization strategies in BP; and it has quantitative support, with respect to measurable data aspect and characterization of the object of study and its frequency of use. For this investigation, we use the corpora of the project Para a Hist?ria do Portugu?s Brasileiro (PHPB), more specifically, the particular, official, reader and redactor letters written between the eighteenth and twentieth centuries, from four states: Minas Gerais, Paran?, Pernambuco and Rio de Janeiro. The results of this research reveal the variation in relativization strategies, in view of the increase in the relativa cortadora (prepositional chopping strategy) percentage in the corpus of this investigation, even though the occurrence of this strategy is more restricted to private letters. In addition, we found factors of cognitive nature such as reduction in cognitive cost and economy related to the occurrence of that relative strategy, principally in private letters; aspects such as the need for expressiveness and clearness related to the use, even if infrequent, of the relativa copiadora (resumptive strategy), especially in official letters; and factors of communicative order such as the public sphere of circulation of the sample letters, as in the redactor and reader letters, and the gap between the parties most directly involved in the use of the standard relative of our sample.

Due to the lack of semantic descriptions of the Web services, service composition becomes a difficult task. To solve this problem, Web services can exploit the use of ontologies for the semantic definition of service s interface, thus facilitating the automation of discovering, publication, mediation, invocation, and composition of services. However, ontology languages, such as OWL-S, have constructs that are not easy to understand, even for Web developers, and the existing tools that support their use contains many details that make them difficult to manipulate. This paper presents a MDD tool called AutoWebS (Automatic Generation of Semantic Web Services) to develop OWL-S semantic Web services. AutoWebS uses an approach based on UML profiles and model transformations for automatic generation of Web services and their semantic description. AutoWebS offers an environment that provides many features required to model, implement, compile, and deploy semantic Web services / Tipicamente servi?os Web cont?m apenas informa??es sint?ticas que descrevem suas interfaces e a falta de descri??es sem?nticas torna a composi??o de servi?osWeb uma tarefa dif?cil.

(THERE) are part of an emerging paradigm in Brazilian Portuguese recently constituted and still developing of forms indicating specificity in indefinite noun phrases (NP). The data that make up the corpus of this research were collected in the following large Brazilian oral corpora: the Corpus Discurso & Gram?tica: a l?ngua falada e escrita na cidade de Natal (FURTADO DA CUNHA, 1998), the Banco Conversacional de Natal (FURTADO DA CUNHA, 2010), the Projeto Varia??o Lingu?stica no Estado da Para?ba VALPB (HORA, 2005) and the Projeto Varia??o Lingu?stica Urbana na Regi?o Sul do Brasil VARSUL (VANDRESEN, 2002). Firstly, the behavior of the specificity markings AQUI, A?, ALI and L? is described with respect to many factors of morphosyntactic and semantic-pragmatic nature: type of construction in which the markers appeared; existence or not of intervening material between the specificity marker item and the NP s nuclear noun; type of noun to which AQUI, A?, ALI and L? are linked; syntactic function of the specified SN; informational status of the NP to which the specificity markers AQUI, A?, ALI and L? are attached; occurrence of conversational implicatures (GRICE, 1982) in the context of use of these specificity markers. Next, a possible grammaticalization trajectory is outlined, according to which AQUI, A?, ALI and L? would had gone from an early spatial deictic indication to the specificity indication. The results point to the existence of forms with varying degree of emergence in this new paradigm of nominal specification, with A? being, probably, the item most grammaticalized, followed by L?, then ALI and AQUI, which permanence in the paradigm do not yet appear to be consolidated / Este trabalho tem como objetivo geral mostrar, com base em propriedades morfossint?ticas e sem?ntico-pragm?ticas, que AQUI, A?, ALI e L? integram, no portugu?s brasileiro contempor?neo, um paradigma emergente de constitui??o recente e ainda em andamento de formas indicadoras de especificidade em sintagmas nominais indefinidos.

Os fatores considerados foram os seguintes: tipo de constru??o em que os marcadores apareceram; exist?ncia ou n?o de material interveniente entre o item marcador de especificidade e o nome nuclear do SN; natureza do substantivo ao qual AQUI, A?, ALI e L? se cliticizam; fun??o sint?tica do SN especificado e status informacional do SN adjungido a AQUI, A?, ALI e L? marcadores de especificidade. Buscou-se, ainda, verificar a ocorr?ncia de implicaturas conversacionais (GRICE, 1982) nos contextos de uso de AQUI, A?, ALI e L? marcadores de especificidade.

Therefore, it is necessary to use methods that can measure these curvatures with good accuracy levels. The preparation of a glide path prior to root canal instrumentation is widely suggested because can avoid possible operative errors, such as loss of centralization and apical transportation, especially in curved root canals. There is no consensus concerning the methods that can be used to measure radicular curvatures, nor regarding the efficacy of glide path. The present investigation has the objective of performing two systematic reviews in order to answer the following questions: 1- What are the methods, described in the literature, used to measure the angles and other characteristics of the curvatures of the root canals? 2- The glide path is able to reduce the apical transportation and the loss of centralization of the endodontic preparation? Also, how does the glide path - manual or engine-driven - result in minor operative errors? Methods: Using the appropriate terms for each review, electronic searches were performed on six databases: PubMed, PubMed Central (PMC), Embase, Scopus, EBSCO Dentistry & Oral Sciences Source (DOSS) and Virtual Health Library (VHL). We used studies published in English or in any language with Latin alphabet. There was no time limit for publications. In addition, in the second review, the included studies, the risk of biases was analyzed. Results: In review 1, about the methods of measurement of curvatures, 6,336 studies were obtained and of these, 31 articles that described innovative methods. Eleven studies described the methods used to measure only the angle of the radicular curvatures, for which they used 2D images. 13 studies also used 2D images, however, in addition to the angles, evaluated other features of the root canal curvatures (position, length, direction, height and shape). In addition, seven studies evaluated curvatures using 3D methods. In review 2, regarding glide path, 2,146 articles were obtained, and 18 studies fulfilled the inclusion criteria, composing the final analysis. 9 studies evaluated the glide path per se and 11 evaluated the impact of glide path on final engine-driven endodontic preparation. Conclusion: Revision 1 suggested that most methods for root canal curvature measurement have potential clinical applications; however, there is a lack of consensus on the ideal technique. In addition to the angle, other features, such as radius and position of curvature, need to be measured and should be considered when evaluating root canal curvature in both clinical and research purposes. Revision 2 revealed that engine-driven confection of glide path, when compared to manual, presents similar or better results of apical transportation and maintenance of root canal centralization. It was also observed that the preparation of glide path, prior to endodontic preparation, is associated with similar results or with a reduction of the apical transportation and the maintenance of the preparation centralization. It was also observed that deviations occur in all situations. / A grande maioria dos condutos apresenta curvaturas e o conhecimento destas curvaturas permite ao cl?nico uma melhor escolha da terap?utica endod?ntica. Para tanto, faz-se necess?rio o emprego de m?todos que possam medir essas curvaturas com bons n?veis de acur?cia. A confec??o de um glide path pr?vio ? instrumenta??o dos canais radiculares ? amplamente sugerida, pois pode evitar poss?veis erros operat?rios, tais como a perda de centraliza??o do preparo e o transporte apical, especialmente em canais radiculares curvos. Como n?o h? consenso quanto aos m?todos que podem ser utilizados na medi??o das curvaturas radiculares, tampouco referente a efic?cia do glide path, a presente investiga??o tem o objetivo de realizar duas revis?es sistem?ticas, a fim de responder ?s seguintes quest?es: 1- Quais s?o os m?todos, descritos na literatura, empregados na mensura??o dos ?ngulos e demais caracter?sticas das curvaturas dos canais radiculares? 2- O glide path ? capaz de reduzir o transporte apical e a perda de centraliza??o do preparo endod?ntico? Al?m disso, qual a forma de confec??o do glide path ? manual ou motorizada ? resulta em menores erros operat?rios? M?todos: Utilizando os termos apropriados para cada revis?o, foram realizadas buscas eletr?nicas em seis bases de dados: PubMed, PubMed Central (PMC), Embase, Scopus, EBSCO Dentistry & Oral Sciences Source (DOSS) e Virtual Health Library (VHL). Foram utilizados estudos publicados em ingl?s ou em qualquer idioma com alfabeto latino n?o houve qualquer limite temporal para as publica??es. Al?m disso, na segunda revis?o, os estudos inclu?dos tiveram o risco de vieses analisado. Resultados: Na revis?o 1, acerca dos m?todos de mensura??o das curvaturas, foram obtidos 6.346 estudos e destes, restaram 31 artigos que descreviam m?todos inovadores. Onze estudos foram descritos a fim de mensurar apenas o ?ngulo das curvaturas radiculares, para isso utilizaram 9 imagens em 2D. 13 estudos utilizaram tamb?m imagens em 2D, entretanto, al?m dos ?ngulos avaliaram outras caracter?sticas das curvaturas dos canais radiculares (posi??o, comprimento, dire??o, altura e forma). Al?m disso, sete estudos avaliaram as curvaturas atrav?s de m?todos em 3D. J? na revis?o 2, a respeito do glide path, obteve-se 2.146 artigos, sendo que 18 estudos preencheram os crit?rios de inclus?o, compondo a an?lise final. 9 pesquisas avaliaram a confec??o do glide path per se e 11 avaliaram a repercuss?o do glide path no preparo endod?ntico motorizado final. Conclus?o: a revis?o 1 sugeriu que a maioria dos m?todos de mensura??o de curvaturas dos canais radiculares tem potenciais aplica??es cl?nicas, no entanto, h? uma falta de consenso sobre a t?cnica ideal. Al?m do ?ngulo, outros fatores, como raio e posi??o da curvatura, precisam ser mensurados e devem ser levados em considera??o ao se avaliar a curvatura do canal radicular tanto em tratamentos cl?nicos como em ambientes de pesquisa. J? a revis?o 2 revelou que a confec??o motorizada, quando comparada com a confec??o manual, do glide path apresenta resultados similares ou melhores de transporte apical e manuten??o da centraliza??o do canal radicular. Observou-se, tamb?m, que a confec??o do glide path, previamente ao preparo endod?ntico, est? associada com resultados similares ou com a redu??o do transporte apical e a manuten??o da centraliza??o do preparo. Tamb?m foi observado que ocorrem desvios em todas as situa??es.
