Full textThis doctoral thesis is an exegetic approach of the triad andin 1Thess, 1Co and Gal. It aims to answer to questions relating to the changes in the way Paul mobilizes the triad, its potentially founding part, its meaning, its origin and the community context which lead the apostle to refer to the triad. After identifying the place of the triad in Pauline corpus (Part 1), a systematic analyse of the occurrences and pericopes, which their theme is connected at least with one of the three concepts, is conducted in order to define the meaning of (Part 2) (Part 3) and (Part 4). The discussion (Part 5) use results of research work to answer to the considered questions. Finally, this doctoral thesis shows that the triad is the expression of a theological thought about Christian being. It constitutes a “summary” intended to be shared by all the believers whom Paul refers with the aim of contributing to do the unity of the Christian communities

Full textHow a speaker can use their posture, gesture, facial expression and voice to create a strong ethos, pistis and sense of trustworthiness is, in this paper, associated with charisma (the power of leadership or authority).
Verbal and nonverbal expressions from three particular speeches by Martin Luther King, John F Kennedy and Bill Clinton have been analyzed in depth. The results show that patos as well as strong nonverbal expression are factors in inspiring devotion or creating enthusiasm. Personal magnetism and radiance is also found to develop through figures of speech and rhetorical devices, including metaphors. Results show that facial expressions, pitch and other prosodic information are not always consciously taken in. Nevertheless, it is questioned whether such information can affect the ethos and pistis developed. This kind of subconscious infliction can be made visible by modern technical equipment. By identifying relevant para- and extralinguistic signals (so called ‘charismatic behaviors’ e.g. intense eyecontact) we can more easily understand why some people affect us greatly, while others go unnoticed.

Full textIn Angiosperms, the pistil of the flower is an organ of extreme importance in plant reproduction and to analyze the function of the genes expressed in the specialized tissues of the pistil is very important for a better understanding of the reproductive process. Through the differential screening of a Nicotiana tabacum stigma/style cDNA library, a cDNA clone (PA3), encoding a protein with high similarity to methyltransferases (SAMT, BAMT and JAMT), has been identified. The gene corresponding to the cDNA (PA3) has been designated NtPMT (Nicotiana tabacum ? Pistil Methyltransferase). The methyltransferases are enzymes involved in processes such as: plant development, defense responses, chemical signaling, pollination, among others. Two cDNA clones (46B11 and 134B02), encoding proteins with high similarity to methyltransferases have been isolated from the TOBEST cDNA library and have been used in heterologous expression experiments. For this purpose, two recombinant plasmids have been constructed, containing a histidine tag in N-terminal fusion with the regions encoding the proteins, under the control of a strong and regulated promoter. The bacterial expression vectors were used for the transformation of different Escherichia coli strains [BL21 (DE3), BL21(DE3) Codon Plus-RP and BL21 (DE3) Rosetta], in order to analyze the expression levels in different growth temperatures (37°C, 30°C and 20°C) and different induction periods (1, 2, 3, 4, 5 and 20 hours). The expression vector pEXP17¬46B11 was used to transform the three strains of E. coli, and the expression vector pEXP17-134B02 has been introduced only in BL21(DE3) Rosetta. In BL21 (DE3), the expected protein (22.7kDa), corresponding to the pEXP17-46B11 clone, has been produced only at 37°C, showing a good expression level already at the first three hours of induction. On the other hand, the strains BL21 (DE3) Codon Plus-RP and BL21 (DE3) Rosetta were capable of producing good quantity of the recombinant protein in all conditions tested. However, the fusion protein (22.7kDa) could be observed only at the insoluble cellular fraction, in the majority of conditions tested, probably as inclusion bodies. However, using 20 h of induction at the temperature of 20°C, it was possible to detect a small quantity of the pEXP17-46B11 recombinant protein in the soluble cellular fraction, a result that has been confirmed by Western blot analyzis. The strain BL21(DE3) Rosetta has also shown good expression levels of the pEXP17-134B02 recombinant protein in all conditions tested. However, the protein with the expected mass (13.9kDa) has been observed only in the insoluble cellular fraction, probably as inclusion bodies. Despite the fact the pEXP17-46B11 protein was insoluble, the good expression levels obtained made possible its use in the production of policlonal antibodies. For this purpose, bands of the recombinant protein obtained in BL21(DE3) Rosetta, induced for three hours at 37ºC, were cut from the poliacrylamide gel and used for the immunization of mouses. Two fragments of the NtPMT gene were amplified by PCR, from genomic DNA of N. tabacum and its putative parental species Nicotiana sylvestris e Nicotiana tomentosiformis. After cloning and sequencing, the obtained fragments were used for comparative sequence analysis, aiming a better understanding of the evolutionary history of this gene in the three Nicotiana species. The results corroborate the hypothesis of the N. tabacum evolutionary origin in which it was originated by the cross between an ancestral of N. sylvestris and an ancestral of N. tomentosiformis.

The main cause comes from the non consideration of the set of parameters which control the flows, therefore wear. The objective of this work is to build the scenario of contact life in term of third body flows and to estimate the contribution of each tribological triplet element on the flows activation. In our case, the tribological triplet is the following: the mechanism (compressor), the first body in contact (rings/cylinder) and the third body. Our approach is composed of the following steps: the state of the art of knowledge on the piston rings from the compressorists point of view, the using of the " conceptual tribological tools " to the studied contacts, the individual study of the triplet elements, the reconstitution of the tribological circuit and the scenario of the contact life in the compressor and then the taking into account the interactions of the triplet elements. This reconstitution is based on dynamic instrumentation of compressor, tests on simulators with in-vivo visualization flows tests, and thermal and mechanical modelings. It leads to the establishment of a phenomenological equation of the third body flows in the contacts rings/cylinder, and the identification of mechanical, materials and physico-chemical parameters which control the t1ows

Full textThe new engine developments are providing engine mechanical and thermal loads increase on the components. Besides the unfavorable wear conditions, the components should provide similar or improved performance compared with current baselines. For piston rings, the performance is given by the ring capacity of sealing and scrapping. These performances can be measured in a engine by the results of lube oil consumption (LOC) and Blow-by. So, the proposal of this work is to evaluate the influence of laser hardening on the second ring wear and verify the sealing and scrapping performance. It was compared two prototypes, being as parameter the current piston ring supplied to customer. Firstly, it was compared the dimensional of the laser hardening effect. After that, it were tested these prototypes in bench tests in order to know the ring performance after laser hardening. In general terms, the superficial treatment by laser on the piston rings surface have showed significant results in the hardness aspects, with some demerits in the dimensional aspect that can interfere in the good functionality of the tribological system, piston rings lubricant cylinder liner.

This study was written from a nonIberian perspective to analyze a phenomenon that is very wellknown in Brazil and which is commonly referred to as malandragem . This social practice is examined from the point of view of a theory of social action, in other words, from the starting point of a Western way of thinking that is in opposition to theories that seek its existence in premodern emotionThis study argues that malandragem is much more a product of our modernity, that has been evident since the beginning of the nineteenth century particularly in the resistance of the dominated groups in society which resulted in the formation of the malandro , malandragem , and manifestations such as the jeitinho (Brazilian way), xaveco (flirting), ginga (swing), darse bem (to do well ) levar vantagem ( to take advantage ) jogo de cintura ( to know how to deal with situations). It is also in that resistance that by allowing malandragem to be accepted as a national characteristic it is possible to hide the latent conflict behind the modern forms of domination that (paradoxically) allow human rights to be advanced. The domination is also accentuated in the interclass relationship which distances those individuals from those rights and moves them closer to malandragem
Este estudo foi escrito numa perspectiva nãoiberista do surgimento e evolução de um fenômeno muito conhecido dos brasileiros ao qual se convencionou chamar de malandragem . Esta prática social é aqui investigada sob a luz de uma teoria social da ação, ou seja, a partir do processo de racionalização do Ocidente, em contraponto às teorias que buscam na emoção prémoderna as causas de sua existência. Na perspectiva deste estudo, é muito mais do formato de nossa modernidade, presente entre nós desde princípios do século XIX, particularmente da resistência dos grupos dominantes e daqueles dominados em admitir a totalidade de seus imperativos, que se forma o malandro, a malandragem e todos os seus pressupostos, tais como, o jeitinho, o xaveco, a ginga, o darse bem, o levar vantagem, o jogo de cintura. É nele também que, ao naturalizar a malandragem como uma marca nacional , podese ocultar o conflito latente onde assentam as formas de dominação modernas que (paradoxalmente) permitem fazer avançar os direitos de cidadania. A dominação entre nós é acentuada também no formato intraclasses, o que distancia os indivíduos desses direitos e os aproxima das coisas da malandragem

Full textThe Last Interglacial Cycle s.l. (between 60 and 130 ky ago) was characterized through registers of two different cores in the Brazilian continental shelf, KF-12, located in Campos Basin and KF-18, located in Santos Basin. First an \"age model\" was established for KF-12, from the KF-18 curve that already had a good cronology. Using Menardii group curve, the biozones from Ericson e Wollin (1968) were established and the difference between the X Zone and the marine isotope stage 5 edges was noticed. The inferred limits for X biozone were 35,6 ky BP (inferior limit) and 82,3 ky BP (superior limit) for KF-18 core and 133,5 and 88,4 ky BP for KF-12 core. In both cores the marine isotope stage (MIS) 5 was between 129,5 and 71,1 ky BP. Other data were also used in the study, such as isotope ratio in planktonic foraminifera, fauna, carbonate content, Ti/Ca and Fe/Ca ratios whereby humidity/dry conditions and continental runoff were inferred. Lastly, the study showed that both the oxygen isotope data from Greenland ice core (NGRIP) and the Antarctic deuterium ratio ranged in a similar way of the δ18O benthonic foraminifera from KF-12 and KF-18, confirming the data synchronism.

Full textThe drastic working conditions of diesiel engines imply piston ring manufacturers to elaborate wear resistant coatings for top position piston ring. The results presented in this study concern the elaboration and characterization of atmospheric plasma sprayed deposits for piston ring. This study received a financial support from Perfect Circle Europe. Firstly, the piston ring-cylinder environment is presented. The consideration of the engine working conditions and the piston ring-cylinder wear mechanisms leads to the definition of a new plasma sprayed piston ring coating : a Mo matrix with a hard TiN reinforcement. The second part is dedicated to the optimization of the elaboration of the previous coating (Mo-NiCrBFeSi) and its tribological and physico-chemical characterization. Wear mechanisms analysis shows the importance of the interlamellar cohesion for tribological applications. The third part concerns the elaboration of a Mo-TiN based plasma sprayed coating from agglomerated and blended powders. Tribological results show the efficiency of the hard phases TiN associated with a NiCrBFeSi binder. Finally, an electrochemical approach is used to estimate the chemical resistance of the coatings in a corrosive environment

Full textSepsis, characterized by inadequate systemic response with organ failure, remains amajor cause of death worldwide. The main mechanisms of sepsis-induced organ dysfunctionare from vascular and inflammatory etiologies. Our hypothesis was that vascular dysfunctioninduced a major drop in perfusion and oxygenation of organs and in turn a deterioration offunction, all of which lead to death.In this multifactorial pathophysiological background, our objective was to investigate2 novel therapeutic approaches able to modulate, one the inflammatory response of failingorgans through the use of erythropoietin (EPO) and the other one the key effector ofvascular dysfunction in sepsis, adrenomedullin (ADM).Our results show that during sepsis:- EPO prevents, inflammatory response and oxidative stress in organs and in theplasma and in turn death. The doses for these cytoprotective effects are high.- the Adrezicumab (ADZ) through the partial inhibition of the ADM and themodulation of vasodilation, rapidly improved, during sepsis, blood pressure and cardiacoutput and could thus prevent the onset of organ dysfunction related to sepsis. IfAdrecizumab prevents vascular, metabolic and cardiac dysfunction during sepsis and/orreduces the need for use of vasopressors, it would open major therapeutic perspectives.In conclusion, all together we provide new evidence that on one hand the use of nonhematopoieticderivatives of EPO could be promising but request further investigations andon the other, the immunologic approach such as targetting ADM could be of high interest inthe treatment of sepsis

Full textENGLISH ABSTRACT: Control of beta-type free-piston Stirling engines has been the topic of research and development for many years. In this dissertation, an alternative approach to free-piston Stirling engine control, namely direct piston displacement control, is proposed. Direct piston displacement control entails the instantaneous and direct control of the piston displacement to control the engine according to preferred criteria, e.g. maximum power conversion or efficiency. To control free-piston engines in this manner, it is necessary to independently control both the displacement of the displacer and the power piston in real time. The primary arrangement by which to achieve this is through external control of the instantaneous forces exerted by the linear electrical machines fixed to the pistons. The challenge of displacement control is whether suitable linear machine technology exists or whether technology could be established that would adhere to the requirements of real time direct control. To answer the question whether direct piston displacement control is at all possible, a process was followed to set specifications that linear machines should adhere to and to set design guidelines for linear machines and free-piston Stirling engines. The first step was to establish the ability to simulate free-piston Stirling engine dynamics accurately. This was done by adapting a second order formulation and to verify and improve the accuracy thereof by comparing simulated results with experimental results of one of the best documented Stirling engines, namely the GPU-3 engine. It was found that this second order formulation could simulate the GPU-3 engine to a fair degree of accuracy. Key indicators were defined and later refined with the view of setting specifications. A case study of the influence of a range of variations, including operational, dimensional and other variations, on the dynamics of the GPU-3 was then undertaken. From the findings of this case study, specifications of the key indicators and design guidelines were established. A design optimisation approach was proposed to evaluate linear machine topologies. This approach makes specific provision for the specifications that linear machines need to adhere to, as well as for representative dynamic responses of the forces exerted on the linear machine by the displacer or the power piston. These representative responses and the associated piston displacement were determined for the displacer, the power piston and the combination of the two from the study conducted to set specifications. An air-core, longitudinal flux linear machine with surface mounted permanent magnets (LFPM) was then evaluated to determine its suitability for direct piston displacement control. This linear machine topology was optimised for the traditional approach to establish a benchmark with which to compare subsequent optimisations. The LFPM linear machine not only compared well with other topologies for the traditional application in resonant free-piston Stirling engines, but it was found also to be able to perform displacement control for both the displacer and the power piston. For both pistons, displacement should however be limited to sinusoidal displacement, and in the case of the displacer, an important qualification is that the linear machine should be assisted by spring forces to reach practical design optimisations. Direct piston displacement control is shown to be possible. Future work should concentrate on the practical implementation thereof in free-piston Stirling engines.
AFRIKAANSE OPSOMMING: Die beheer van beta-tipe vrysuier Stirling enjins is al vir baie jare die onderwerp van navorsing en ontwikkeling. In hierdie proefskrif word ’n alternatiewe benadering tot vrysuier Stirlingenjins voorgestel, naamlik direkte suierverplasingsbeheer. Direkte suierverplasingsbeheer behels die oombliklike en direkte beheer van die suierverplasing om die enjin volgens voorkeur kriteria, soos maksimum drywingsomsetting of benuttingsgraad, te beheer. Om vrysuier enjins op hierdie wyse te beheer, is dit noodsaaklik om intyds die verplasing van beide die verplaser en die werksuier onafhanklik te beheer. Die primêre wyse om dit te bereik is deur eksterne beheer van die oomblikskragte wat uitgevoer word deur die lineêre masjiene wat vas is aan die suiers. Die uitdaging van verplasingsbeheer is of toepaslike lineêre masjien tegnologie bestaan en of tegnologie gevestig kan word wat sal voldoen aan die vereistes van intydse direkte beheer. Om die vraag te beantwoord of direkte suierverplasingsbeheer hoegenaamd moontlik is, is ’n proses gevolg om spesifikasies daar te stel waaraan lineêre masjiene moet voldoen en om ontwerpsriglyne vir lineêre masjiene en vrysuier Stirling enjins te stel. Die eerste stap was om die vermoë daar te stel om vrysuier Stirling enjin dinamika akkuraat te simuleer. Dit is gedoen deur ’n tweede orde formulering aan te pas en om die akkuraatheid daarvan te kontroleer en te verbeter deur gesimuleerde resultate met eksperimentele resultate van een van die bes gedokumenteerde Stirling enjins, naamlik die GPU-3 enjin, te vergelyk. Daar is bevind dat die tweede orde formulering die GPU-3 tot ’n redelike mate akkuraat kon simuleer. Sleutel aanwysers is gedefinieer en later verfyn met die oog op die daarstelling van spesifikasies. ’n Gevallestudie van die invloed van ’n reeks variasies, insluitende operasionele, dimensionele en ander variasies, op die dinamika van die GPU-3 is onderneem. Gegrond op die bevindinge van hierdie gevallestudie kon spesifikasies en ontwerpsriglyne vasgestel word. ’n Ontwerpsoptimeringsbenadering is voorgestel om lineêre masjiene te evalueer. Hierdie benadering maak spesifiek voorsiening vir die spesifikasies waaraan lineêre masjiene moet voldoen, sowel as verteenwoordigende dinamiese response van die kragte wat op die lineêre masjien van die verplaser en die werksuier uitgeoefen word. Vanaf die bevindinge van die studie wat uitgevoer is om spesifikasies daar te stel, is verteenwoordigende response en gepaardgaande suierverplasing bepaal vir die verplaser, die werksuier en die kombinasie van die twee. ’n Lugkern, longitudinale vloed lineêre masjien met oppervlak-gemonteerde permanente magnete (LVPM) is toe geëvalueer om die geskiktheid daarvan te bepaal vir direkte suierverplasingsbeheer. Hierdie lineêre masjien topologie is geoptimeer vir die tradisionele benadering om ’n maatstaf te vestig waarteen daaropvolgende optimerings vergelyk kan word. Die LVPM lineêre masjien vergelyk nie net goed met ander topologieë vir die tradisionele toepassing in resonante vrysuier Stirling enjins nie, maar daar is ook bevind dat dit in staat is om verplasingsbeheer te doen vir beide die verplaser en die werksuier. Vir beide suiers moet die verplasing egter tot sinusvormige verplasing beperk word en in die geval van die verplaser, is ’n belangrike kwalifikasie dat die lineêre masjien ondersteun moet word deur veerkragte om praktiese ontwerpsoptimerings te bereik. Daar is aangetoon dat direkte suierverplasingsbeheer moontlik is. Toekomstige werk moet konsentreer op die praktiese implementering daarvan in vrysuier Stirling enjins.

Resumo: As oclusopatias estão entre os problemas enfrentados na saúde pública, devido à alta dimensão epidemiológica na fase infantil, sendo o terceiro problema odontológico em saúde pública de acordo com a Organização Mundial de Saúde (OMS). Dentre elas, destacam-se as mordidas cruzadas, que consistem na incapacidade dos dois arcos em ocluir normalmente no relacionamento lateral ou anteroposterior. Se não forem solucionadas com uma intervenção precoce, podem comprometer a estrutura craniofacial, as estruturas do aparelho estomatognático, a interação social e psicológica do indivíduo. Dessa forma, é adequada a aplicação de métodos preventivos, a fim de reduzir esses males de saúde pública e assegurar a qualidade de vida dos pacientes. Objetivou-se, no Capítulo 1, relatar um caso clínico de uma criança com mordida cruzada posterior unilateral, tratada com o método das Pistas Diretas Planas (PDP); e, no Capítulo 2, avaliar a efetividade da Reabilitação Neuroclusal (RNO) com o uso das PDP, por meio das análises de modelos de gesso e radiografias panorâmicas. Trata-se de um estudo clínico, seguindo o protocolo de RNO, com a utilização das PDP. Nesse sentido, desgastaram-se as interferências oclusais e se confeccionaram pistas em planos inclinados utilizando resina composta, a fim de promover o equilíbrio oclusal.

Abstract: Occlusions diseases are in the public health problems due to their high epidemiological dimension during the infantile phase and are considered by the World Health Organization the third dental problem in public health. Among them, cross bites are highlighted, which is the inability of the two arches to occlude normally in the lateral or anteroposterior relationship. If not solved with an early intervention, it can compromise the craniofacial structure, the structures of the stomatognathic apparatus, the social and psychological interaction of the individual. In this way, it is appropriate to apply preventive methods in order to reduce these public health ills, as well as to ensure the quality of life of patients. The objective of Chapter 1 was to report a clinical case of a child with unilateral posterior crossbite treated with the planas direct tracks method and in Chapter 2 to evaluate the effectiveness of the neuroclusal rehabilitation with the use of planas direct tracks through the analysis of models of gypsum and panoramic radiographs. It is a clinical study, following the RNO protocol with the use of planas direct tracks, wear on occlusal interferences and the preparation of slopes in inclined planes using composite resin, in order to promote the occlusal balance, performed with 21 children from 3 to 6 years of age studing in the Municipal Schools of Basic Education of a Brazilian municipality. Using a graphite tip, the reference points were marked on each gypsum model of both arcs, the intercanine and intermolar distances to measure with a digital caliper. Panoramic radiographs were marked cephalometric points of the mandibular branch performed with ImageJ software. In the data analysis the software Bioestat 5.0 and Graphpad prism 7.0 were used.

Occlusions diseases are in the public health problems due to their high epidemiological dimension during the infantile phase and are considered by the World Health Organization the third dental problem in public health. Among them, cross bites are highlighted, which is the inability of the two arches to occlude normally in the lateral or anteroposterior relationship. If not solved with an early intervention, it can compromise the craniofacial structure, the structures of the stomatognathic apparatus, the social and psychologi cal interaction of the individual. In this way, it is appropriate to apply preventive methods in order to reduce these public health ills, as well as to ensure the quality of life of patients. The objective of Chapter 1 was to report a clinical case of a child with unilateral posterior crossbite treated with the planas direct tracks method and in Chapter 2 to evaluate the effectiveness of the neuroclusal rehabilitation with the use of planas direct tracks through the analysis of models of gypsum and panoramic radiographs. It is a clinical study, following the RNO protocol with the use of planas direct tracks, wear on occlusal interferences and the preparation of slopes in inclined planes using composite resin, in order to promote the occlusal balance, performed with 21 children from 3 to 6 years of age studing in the Municipal Schools of Basic Education of a Brazilian municipality. Using a graphite tip, the reference points were marked on each gypsum model of both arcs, the intercanine and intermolar distance s to measure with a digital caliper. Panoramic radiographs were marked cephalometric points of the mandibular branch performed with ImageJ software. In the data analysis the software Bioestat 5.0 and Graphpad prism 7.0 were used. In the analysis of the models, we evaluated the intercanine distances that the statistical significance of the measurements before and after the treatment in the superior models, with value of p <0.0001. In the lower models for the same measure with p value <0.0044. In the intermolar evaluation, here was statistical significance only for the upper measurements p <0.0027. In the radiographic analysis, the cephalometric measures of condyle height at the base of the mandible and width were evaluated, being the right width before and a fter with p value <0.0918 and left with a p <0.0149. At the end of the treatment the difference between the right and left widths was p <0.0001 and the difference of the heights of p <0.0002. The difference between the height and the width of the right and left sides at the beginning was greater than the end of the treatment, which shows the previous growth was asymmetric and after the uncrossing, a symmetrical growth. It was concluded that the functional cross - bite was corrected by the treatment of the planas direct tracks, favorable clinical result was achieved, which demonstrated the effectiveness of the technique, and because of easy execution and use of daily dental materials, should be applied in public service and in private.
As oclusopatias estão entre os problemas enfrentados na saúde pública, devido à alta dimensão epidemiológica na fase infantil, sendo o terceiro problema odontológico em saúde pública de acordo com a Organização Mundial de Saúde (OMS). Dentre elas, destacam-se as mordidas cruzadas, que consistem na incapacidade dos dois arcos em ocluir normalmente no relacionamento lateral ou anteroposterior. Se não forem solucionadas com uma intervenção precoce, podem comprometer a estrutura craniofacial, as estruturas do aparelho estomatognático, a interação social e psicológica do indivíduo. Dessa forma, é adequada a aplicação de métodos preventivos, a fim de reduzir esses males de saúde pública e assegurar a qualidade de vida dos pacientes. Objetivou-se, no Capítulo 1, relatar um caso clínico de uma criança com mordida cruzada posterior unilateral, tratada com o método das Pistas Diretas Planas (PDP); e, no Capítulo 2, avaliar a efetividade da Reabilitação Neuroclusal (RNO) com o uso das PDP, por meio das análises de modelos de gesso e radiografias panorâmicas. Trata-se de um estudo clínico, seguindo o protocolo de RNO, com a utilização das PDP. Nesse sentido, desgastaram-se as interferências oclusais e se confeccionaram pistas em planos inclinados utilizando resina composta, a fim de promover o equilíbrio oclusal. Tal pesquisa foi feita com 21 crianças de três a seis anos de idade, matriculadas nas escolas municipais de educação básica (EMEBs) de um município brasileiro. Com uma ponta grafite, marcaram-se os pontos de referência em cada modelo de gesso de ambos os arcos, das distâncias intercaninas e intermolares, para efetuar as medidas por meio de paquímetro digital. Nas radiografias panorâmicas, foram marcados pontos cefalométricos do ramo mandibular por meio do software ImageJ. Na análise dos dados, empregaram-se os programas Bioestat 5.0 e Graphpad prism 7.0. Na análise dos modelos, avaliaram-se as distâncias intercaninas, em que se observou a significância estatística das medidas antes e após o tratamento nos modelos superiores, com valor de p<0,0001 e, nos modelos inferiores para a mesma medida, com valor de p<0,0044. Já na avaliação intermolar, houve significância estatística apenas para as medidas superiores (p<0,0027). Na análise radiográfica foram avaliadas as medidas cefalométricas da altura do côndilo à base da mandíbula e largura, sendo a largura direita antes e depois com valor de p<0,0918, e esquerda, de p<0,0149. Ao final do tratamento, a diferença entre as larguras direita e esquerda foi de p<0,0001, e a das alturas, de p<0,0002. A diferença entre a altura e a largura dos lados direito e esquerdo no início foi maior que no final do tratamento, isso demonstra que o crescimento anterior se dava de forma assimétrica e, após o descruzamento, um crescimento simétrico. Conclui-se que foi corrigida a mordida cruzada funcional pelo tratamento das PDP, e o resultado clínico favorável foi alcançado, o que indica a efetividade da técnica que, por ser de fácil execução e utilizar materiais do cotidiano do consultório odontológico, deve ser aplicada tanto no serviço público como no particular.

Esta dissertação investiga o uso de pistas de fronteira de sintagma entoacional (IP) no processamento de sentenças coordenadas por adultos falantes do português brasileiro (PB). Pesquisas desenvolvidas na subárea da Psicolinguística denominada Processamento de Sentenças discutem em que medida as decisões iniciais do parser – processador linguístico humano – seriam guiadas por informações estritamente sintáticas ou, também, por outras informações de natureza linguística ou extralinguística. Para isso, a compreensão de sentenças estrutural e temporariamente ambíguas, conhecidas na literatura como sentenças garden-path, tem sido testada usando-se diferentes técnicas e tarefas experimentais, e resultados experimentais sugerem que falantes adultos usam a prosódia como fonte de informação no processamento (p.ex., KJELGAARD e SPEER, 1999; CLIFTON et al, 2002; MILLOTTE et al, 2007; DEDE, 2010; FONSECA, 2012). Buscando contribuir para essa discussão, elegemos uma estrutura pouco investigada nos estudos da área, particularmente, no PB – sentenças com DPs coordenados, cuja ambiguidade é desfeita por meio da prosódia ([O juiz intima João]IP [e Pedro e Lucas aguardam o resultado final]IP – [O juiz intima João e Pedro]IP [e Lucas aguarda o resultado final]IP). Usamos a técnica de restauração de fonema mascarando a marcação de número no verbo, de modo a verificar se falantes nativos do PB reconhecem um sujeito simples ou composto com base em pistas de fronteira de IP. Conduzimos dois experimentos com a tarefa de escolha visual de palavras (STOYNESHKA et al, 2010), e dois experimentos foram aplicados utilizando-se a técnica de comparação sentença-figura, com o recurso de manipulação de atenção. Tal procedimento nos permitiu verificar a recuperação de um estímulo na memória de trabalho e a comparação de estímulos linguísticos e visuais na compreensão de uma sentença. Nossa hipótese de trabalho é a de que a informação prosódica pode auxiliar a construção mental do significado de uma sentença. Os resultados sugerem que o parser leva em conta a informação prosódica, uma vez que as respostas dos participantes são compatíveis com o contorno entoacional de cada estímulo.
This study investigates the use of Intonational Phrase (IP) boundary cues on syntactic processing by Brazilian Portuguese (henceforth, BP) adult speakers. Several studies conducted in the psycholinguistic subarea called Sentence Processing discuss to what extent the initial decisions of the parser – human language processor – would be guided by strictly syntactic information, or also by other linguistic or extra linguistic information. For this, the comprehension of the structurally and temporarily ambiguous sentences – garden-path sentences – has been tested using different techniques and experimental tasks, and experimental results suggest that adult speakers use prosody as a source of information in sentence processing (e.g. KJELGAARD & SPEER, 1999; CLIFTON et al, 2002; MILLOTTE et al, 2007; DEDE, 2010; FONSECA, 2012). In order to contribute to this discussion, we chose a little-investigated structure in our area of studies, specially, in BP – sentences with coordinated DPs, for which ambiguity is undone by prosody ([The judge intimates João]IP [and Pedro and Lucas await (for) the final result]IP – [The judge intimates João and Pedro]IP [and Lucas awaits (for) the final result]IP). We use the phoneme restoration technique masking the number marking on the verb, in order to check if PB native speakers recognize a simple or conjoint subject based on IP boundary cues. We conducted two experiments using the visual word choice task (STOYNESHKA et al, 2010), and two experiments were applied using the sentence-image verification technique, with attention manipulation resource. This procedure allowed us to verify the recovery of a stimulus in working memory and the comparison of linguistic and visual stimuli in the comprehension of a sentence. Our working hypothesis is that the prosodic information can help the mental construction of the meaning of a sentence. Results suggest that the parser takes into account the prosodic information, since the participants' answers are compatible with the intonation of each stimulus.

In the history of contemporary dance, the recurrent hybridization with other artistic languages has opened trial routes and formed creative plans of some consistency that consider dance in its aesthetic, political and affective strength. Since its emergence and consolidation as body practice, Somatic Education has been resounding significantly with dance, occupying a place and a recognized status of "knowing about the body" that precludes a pedagogical model order and form in favor of an appreciation of the feelling and the disintegration of the concept of representativeness. Some concerns echo the need for research on the possible territory in which they operate somatic methods: how does somatic education enables danced gesture? What are its main contributions to creation in contemporary dance? What anatomy would walk through the territories of somatic and dance approaches, such territories beeing so loose, given the breakups and deconstructions of the contemporary panorama? Facing this background, the present study aims to investigate, explore and promote the reverberations, connections and possible resonances arising from the somatic practice, in order to provide subsidies to enrich the processes of creation and artistic expression in contemporary dance. Such study is anchored in the mapping method and operates with some concepts of philsophers as Deleuze and Felix Guattari, Michel Bernard, Laurence Louppe and Josà Gil, and researchers as Hubert Godard.

Full textSmokers selectively attend to smoking-related cues, an implicit cognitive process called attentional bias (AB). However, it is unclear whether former smokers present AB. Therefore, we evaluated the influence of abstinence time in VA in 62 exsmokers (50 ± 11 years-old) through a visual probe task. Participants avoided smoking cues despite of abstinence time. This avoidance was more pronounced in longer stimuli exposition. Former smokers also attributed little emotional valence to smoking cues and reported low craving rates both before and after the task. The negative AB and low emotional valence of smoking cues might constitute a process of attentional modulation typical of longer abstinence, in which cognitive strategies are employed to maintain this state. The results contribute to the understanding of implicit cognition in addiction and its importance to smoking treatment and prevention.

With the growth of world population and the advent of industrialization, the demand for abundant and profitable food production worldwide is increasing. There is then a need for strategies that minimize loss and changes in food products, especially those that are grown for long periods of time like grains and vegetables. In this bias arise the pesticides, marketed since the nineteenth century, increasingly specialized and chemically modified to achieve greater efficiency in pest elimination and a shorter period of time. When pesticides are used correctly, they minimize grain losses by over 40%, but when used improperly or above the recommended dosage, they can lead to environmental and public health impacts. In this context, Clomazone (2 - (2-chlorobenzyl) -4,4-dimethyl-1,2-oxazolidin-3-one), active principle of the commercial herbicide Gamit®, of the Isoxazolidinone family and belonging to toxicological class III is Of broad spectrum used for the control of annual grasses and broadleaf weeds in cotton, peas, squash, soybeans, sweet potatoes, tobacco, wheat and rice. However, this herbicide has a series of physico-chemical characteristics and distinct behavior depending on the environment where it is inserted which can cause the increase of its permanence in the environment and contamination of organisms that are not its origin targets. An alternative to reduce the environmental impact caused by herbicides is phytoremediation. Phytoremediation consists of a technique of removal and / or pollutants from environments using plants as environmental remediation agents. This study aimed to evaluate the ability of the Pistia Stratiotes plant species in phytoremediation of the herbicide clomazone in its commercial form of water resources. The assay lasted 24 days and counted on two herbicidal concentrations that were determined from the one hundred fold multiplication of the dose recommended for use in crops, setting up an acute exposure to the herbicide. The clomazone degradation kinetics analyzes were performed by analytical methods by high performance liquid chromatography coupled to a detector with CLAE-DAD diode array. After 24 days of experiment, it was possible to identify that the plant species was able to reduce the presence of the herbicide clomazone in water by 90% and also that despite the water exposure to P. stratiotes does not undergo morphological changes due to sensitivity to the compound. Thus, the results indicate that Pistia Straiotes is capable of phytoremediation of the herbicide clomazone of water resources.
Com o crescimento da população mundial e o advento da industrialização cada vez mais aumenta a demanda pela produção abundante e rentável de alimentos pelo mundo todo. Existe então a necessidade de estratégias que minimizem a perda e as alterações nos produtos alimentares, sobretudo os que são cultivados por longos períodos de tempo como grãos e hortaliças. Neste viés surgem os pesticidas, comercializados desde o século XIX, cada vez mais especializados e modificados quimicamente para atingir uma maior eficiência na eliminação de pragas e um menor período de tempo. Quando os pesticidas são usados corretamente, eles minimizam acima de 40% as perdas de grãos, mas quando usados de maneira incorreta ou acima da dosagem recomendada, podem conduzir a impactos no ambiente e na saúde pública. Neste contexto, o Clomazone (2 - (2-clorobenzil) -4,4-dimetil-1,2-oxazolidin-3-ona), princípio ativo do herbicida comercial Gamit®, da família das Isoxazolidinona e pertencente a classe toxicológica III é de amplo espectro usado para o controle de gramíneas anuais e plantas daninhas de folha larga em algodão, ervilhas, abóbora, soja, batata-doce, tabaco, trigo e arroz. Porém, este herbicida possui uma série de características físico-químicas e comportamento distinto dependentemente do ambiente onde for inserido o que pode causar o aumento de sua permanência no ambiente e contaminação de organismos que não são os seus alvos de origem. Uma alternativa para reduzir o impacto ambiental causado pelos herbicidas é a fitorremediação. A fitorremediação consiste em uma técnica de remoção e/ou de poluentes dos ambientes utilizando plantas como agentes de remediação ambiental. Este estudo teve como objetivo avaliar a capacidade a espécie vegetal Pistia stratiotes em fitorremediar o herbicida clomazone em sua forma comercial de recursos hídricos. O ensaio teve a duração de 24 dias e contou com duas concentrações o herbicida que foram determinadas a partir da multiplicação em cem vezes da dose recomendada para uso em lavouras, configurando uma exposição aguda ao herbicida. As análises da cinética de degradação do clomazone foram realizadas através de métodos analíticos por cromatográfica líquida de alta eficiência acoplada a detector com arranjo de diodos CLAE-DAD. Após os 24 dias de experimento foi possível identificar que a espécie vegetal foi capaz de reduzir em 90% a presença do herbicida clomazone na água e também que apesar da exposição agua a P. Stratiotes não sofre alterações morfológicas em decorrência de sensibilidade ao composto. Dessa maneira, os resultados indicam que a Pistia Straiotes é capaz de fitorremediar o herbicida clomazone de recursos hídricos.

Esta é uma pesquisa pautada na demonstração da importância dos processos metafóricos e de seu valor cognitivo. Os objetivos são: investigar se e quando as pistas linguísticas, cognitivas, lexicais e contextuais tiveram papel decisivo no processamento de instâncias metafóricas específicas e identificar as restrições que permitem ao ouvinte interpretar o enquadre da metáfora. Pretende-se responder às seguintes perguntas: Qual é a contribuição relativa de cada uma das restrições? Houve diferença significativa no resultado das tarefas no que diz respeito à contribuição relativa (CR) das restrições para a ativação de determinada interpretação? A hipótese deste trabalho é de que diante de uma instância metafórica seu processamento (interpretação) é determinado por restrições lexicais (restrições impostas pelo priming lexical dos elementos que ocorrem na posição de tópico dessas metáforas), restrições cognitivas (se os esquemas imagéticos transpostos de um domínio para o outro cognitivamente são de fato acionados pelos ouvintes em forma de metáforas) e restrições contextuais. Para este estudo, foi proposto que essas restrições interferem no processamento de metáforas porque a linguística cognitiva, referencial teórico de base para esta pesquisa, apesar de exaustivamente se preocupar com os processos metafóricos, ainda não apontou qual das variáveis, cognitiva, lexical ou contextual, a priori, tem papel decisivo no processamento metafórico. No Brasil, a linguística cognitiva não possui amplo histórico de estudos com experimentação e isso faz com que a presente pesquisa seja importante. Ao se ter uma questão não respondida, observa-se que há uma questão com suficiência teórica, pois a linguística cognitiva abria um espaço no qual esta tese pudesse ser incluída, justificando, assim, a pertinência deste trabalho, cujos objetivos foram mencionados anteriormente. Além de ser uma tese experimentalista, por tratar de processos metafóricos, é também semântica, pois ?a linguística cognitiva defende que a relação entre palavra e mundo é mediada pela cognição e que o significado deixa de ser um reflexo direto do mundo e passa a ser visto como uma construção cognitiva através da qual o mundo é aprendido e experienciado?. (FERRARI, 2011, p. 14). Esta é uma pesquisa que pretende se embasar, principalmente, em conceitos e perspectivas apresentadas pela semântica cognitiva. Desse modo, aborda-se a linguística cognitiva e os estudos semânticos, as noções de frame e a metáfora na linguística cognitiva. Esta proposta apoia Moura (2007, p. 418), para quem a interpretação da metáfora é guiada pelo contexto, o qual estabelece um parâmetro para a interpretação, sendoque o falante produz enquadres excludentes (PINKER, 2008), mas pistas linguísticas (MOURA, 2007) permitem a interpretação por parte do ouvinte. Evidencia-se a conexão entre as restrições contextuais e as restrições cognitivas e o fato de que o "contexto abrange o conjunto de informações compartilhadas relevantes num dado momento da conversação (MOURA, 2006, p. 89)".
Abstract : This research is guided by the demonstration of the importance of metaphorical processes and their cognitive value. The objectives are: to investigate if and when the linguistic, cognitive, lexical and contextual cues played a decisive role in the processing of specific metaphorical instances and identify the constraints that allow the listener to interpret the metaphor frame. It is intended to answer the following questions: What is the relative contribution (RC) of each of the restrictions? Was there a significant difference in the outcome of tasks with respect to the relative contribution of restrictions to the activation of a particular interpretation? The hypothesis is that a metaphorical instance processing (interpretation) is determined by lexical constraints (constraints imposed by lexical priming of elements that occur in the topic position of these metaphors), cognitive constraints (whether image schemes transposed from one domain to another are indeed cognitively accessed by listeners in the form of metaphors) and contextual constraints. For this study, it was proposed that these restrictions interfere with the processing of metaphors because cognitive linguistics, the basic theoretical framework for this research, although thoroughly worrying about the metaphoric processes, has not yet pointed which variables: cognitive, lexical or contextual, a priori, have a decisive role in the metaphorical processing. In Brazil, cognitive linguistics has few studies in experimentation and this makes this research important. When one has an unanswered question, it is observed that there is an issue with theoretical sufficiency, cognitive linguistics opened a space in which this thesis could be included, thus justifying the relevance of this work, whose goals were mentioned above. Besides being an experimentalist theory for dealing with metaphorical processes, but it isalso semantic, because "cognitive linguistics argues that the relationship between word and world is mediated by cognition and meaning ceases to be a direct reflection of the world and becomes cognitive seen as a construction through which the world is experienced and learned (FERRARI 2011, p. 14)?. This is a survey that is based primarily on concepts and perspectives presented by cognitive semantics. Thus, it has addressed the cognitive linguistic and semantic studies, the notions of frame and metaphor in cognitive linguistics. This proposal supports Moura (2007, p . 418), for whom the interpretation of metaphor is context-driven, which sets a parameter for the interpretation being that the speaker produces exclusionary framings (Pinker, 2008), but linguistic clues (Moura, 2007) allow the interpretation by the listener. It also highlights the connection betweenthe contextual constraints and cognitive constraints and the fact that the "context includes the set of shared relevant information at any given time of the conversation (Moura, 2006, p. 89)".

A sociedade faz parte do contexto de cada indivíduo como forma de integrá-lo à comunidade. Sendo assim, esta pesquisa aborda um tema que busca integrar todos os cidadãos da cidade num espaço chamado calçada. A Lei 10.098/2000, que estabelece normas gerais e critérios básicos para a promoção da acessibilidade das pessoas com deficiência ou com mobilidade reduzida, regulamenta a supressão das barreiras arquitetônicas das vias e espaços públicos, obstáculos, edificações, comunicação e transporte. Sendo decretada em 2004 (Decreto 5.294/2004), a lei orienta a adaptação dos espaços públicos diante da NBR 9050 (Norma Técnica de Acessibilidade a edificações, mobiliário, espaços e equipamentos urbanos). A acessibilidade é considerada o básico de todos os fatores que visam à inclusão social das pessoas com deficiência. Nesta pesquisa a acessibilidade está voltada para as calçadas, pois estes são espaços públicos abertos, onde cada indivíduo pode dizer-se livre e com direito de fazer suas escolhas. As calçadas, hoje, recebem um novo produto que viabiliza o sistema de mobilidade das pessoas com deficiência visual e demais indivíduos: os PISOS TÁTEIS. Este sistema visa a sinalizar o percurso, chamando a atenção para as barreiras e obstáculos inoportunos, bem como orientando o usuário a chegar a algum destino. Os pisos táteis nasceram na década de 60, a fim de minimizar os acidentes ocorridos nas estações de trens e metrôs do Japão. Os pisos táteis fazem parte da normatização brasileira desde 2004, e várias cidades ainda estão buscando melhoramentos nas suas calçadas de acordo com a NBR 9050/2004. Contudo, esta pesquisa busca tanto o entendimento deste sistema de mobilidade como também o reconhecimento da Ilha de Santa Catarina, a qual teve a primeira aplicação dos pisos táteis em 1998. Para alguns, como centro de planejamento urbano da cidade, a Ilha foi pioneira no Brasil em implantar a acessibilidade nas calçadas urbanas. Porém, a realidade que segue nos dias atuais acaba não demonstrando sucesso na iniciativa. Para proceder esta pesquisa foi elaborada uma metodologia que utilizou três abordagens para contemplar e validar os estudos. Esta metodologia foi desenvolvida em etapas distintas iniciando pelas tabelas de diagnósticos das calçadas, que buscam reconhecer o local e os problemas que Florianópolis tem, correlacionando-os com a normatização existente. Em seguida, o passeio acompanhado das pessoas com deficiência e mobilidade reduzida, a fim de vivenciar suas dificuldades em se locomover nas calçadas e por fim o grupo de foco, o qual busca soluções para as calçadas de Florianópolis. Após este estudo, seguem as diretrizes para a acessibilidade nas calçadas de Florianópolis, considerando suas características de infraestrutura e atribuindo os princípios do desenho universal.

Full textThe biology of plant sexual reproduction is a research field of great importance, since most of the food consumed by humans is composed of plant reproductive parts (fruits and seeds), originated by the development of fertilized pistil parts. In Nicotiana tabacum, it was identified a stigma/style-specific gene, SCI1 (Stigma/style Cell-cycle Inhibitor 1), which acts in the inhibition of cell proliferation (DePaoli et al., 2011). Through pull down assays, the interaction of the SCI1 protein with a cyclin-dependent protein kinase (CDK) was verified (Strini, unpublished). This work aimed the characterization of this new CDK, orthologous to the Arabidopsis CDKG;2. The N. tabacum corresponding sequence (NtCDKG;2) was PCR amplified, from stigmas/styles cDNAs, cloned and sequenced, which allowed the confirmation of its identity. The NtCDKG;2 expression was analyzed in the different vegetative and reproductive organs, by qRT-PCR, evidentiating an ubiquitous expression pattern. Studying the expression pattern of this gene in stigmas/styles of the twelve stages of N. tabacum flower development, it was observed that NtCDKG;2 is more expressed at the later developmental stages towards anthesis, indicating an important function of its protein in the end of pistil development. NtCDKG;2 expression analyses in stigmas/styles of N. tabacum plants with an enhanced auxin production in the pistil suggest that NtCDKG;2 is transcriptionally regulated by this hormone. The transient expression of the fusion protein NtCDKG;2-GFP, in N. tabacum leaves, evidentiated the nuclear localization of the studied protein. Stable transgenic plants overexpressing and silencing NtCDKG;2 by RNAi were also generated. Despite the high transcript levels in the plants overexpressing NtCDKG;2 and the low transcript levels in the silencing plants, macroscopic phenotypic alterations were not observed on these plants. Additionally, the expression of the NtCDKG;2 protein, with a histidine tag fused in its N-terminal, was obtained in Escherichia coli BL21(DE3)CodonPlusRP cells. Through studies performed on this work and literature analyses, it is possible to propose that NtCDKG;2 encodes a protein that is involved in the control of cell cycle at the N. tabacum stigmas/styles.

Resumo: Em matas de restinga da Ilha do Cardoso (SP), forrageadoras da formiga arborícola crepuscular/noturna Odontomachus hastatus podem caçar a > 8 m do ninho. O forrageamento se dá principalmente no dossel, em uma intricada rede de galhos, onde esta formiga deve ser capaz de aprender o caminho de retorno ao ninho. O ambiente do dossel e seu hábito noturno tornam esta espécie um interessante modelo para pesquisa em orientação espacial. Para investigar os mecanismos de orientação empregados por O. hastatus, realizamos experimentos sob condições controladas em laboratório, usando uma arena circular onde marcas visuais e químicas poderiam ser manipuladas. Testamos a influência de: (i) um padrão de dossel artificial; (ii) pistas visuais horizontais; (iii) uma pista tridimensional (cilindro); e (iv) pistas químicas na superfície do chão da arena. Nossos resultados demonstram que O. hastatus se guia principalmente por pistas visuais (pistas do dossel e pistas horizontais), o que está de acordo com o encontrado em formigas diurnas. A luminosidade noturna (lua/estrelas) é aparentemente suficiente para produzir silhuetas contrastantes do dossel e vegetação circundante, e podem ser importantes referenciais de orientação. Por outro lado, substâncias químicas não funcionaram como pistas para o retorno de forrageadoras. Ao contrário do chão plano da arena circular, é possível que marcas químicas sejam importantes na marcação de rotas arbóreas bifurcadas de O. hastatus. O uso de pistas químicas por formigas é geralmente considerado importante para orientação noturna e este trabalho é a primeira demonstração experimental do uso de pistas visuais por uma formiga noturna e arborícola. O presente estudo contribui para o desenvolvimento de estudos comparativos sobre a evolução da orientação espacial em formigas e outros insetos.
Abstract: In the 'restinga' sandy plain forest of Ilha do Cardoso (SP), foragers of the crepuscular/nocturnal arboreal ant Odontomacus hastatus may hunt > 8 m away from their nests. Foraging takes place mainly in the canopy amongst the intricate net of branches and bifurcations, where ant foragers must be able to learn the way back to the nest. The canopy environment together with the nocturnal habit makes this species an interesting model for research on spatial orientation. In order to investigate orientation mechanisms employed by O. hastatus, we performed controlled laboratory experiments using a circular arena where chemical and visual cues could be manipulated. We tested the influence of: (i) an artificial canopy pattern; (ii) horizontal visual cues; (iii) a tridimensional cue (cylinder); (iv) chemical cues on the ground surface. Our results demonstrate that O. hastatus is guided mainly by visual cues (canopy and horizontal cues), which is in accordance with other diurnal arboreal ants. Nocturnal luminosity (moon/stars) is apparently sufficient to produce contrasting silhouettes from the canopy and surrounding vegetation, which may be important as orientation references. On the other hand, chemical substances provided no cues to returning foragers. Contrary to the plain floor of the circular arena, it is possible that chemical cues are important for marking bifurcated arboreal routes of O. hastatus. The use of chemical cues by ants is generally considered
