Haase, Christian. "Neue Auxiliare für die Peptidfragmentverknüpfung." Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2010. http://dx.doi.org/10.18452/16140.
Full textIn this thesis approaches for convergent synthesis of peptides have been developed. In the extended native chemical ligation so far space demanding auxiliaries encumbered challenging condensations. Furthermore the required drastic acidolytic cleavage conditions were furthermore incompatible with many post-translational modifications. In the thesis a nouvelle less space demanding scaffold was scrutinized which allowed a milder basic cleavage. Therefore a small electron-accepting substituent was introduced that enabled the induction of an elimination reaction liberating the target peptide after the peptide ligation had taken place. Furthermore the applicability of the commercially available penicillamine as precursor of valine in the ligation-desulfurization strategy could be demonstrated. Finally the ligation with sequence internal cysteines was scrutinized. Herein it could be shown that certain peptides with cysteine in a distinctive position of the sequence preferable reacted in thioester-based condensation reactions.

Full textChemoselective ligation methods are an essential element of chemical peptide and protein synthesis. The search of a „universal tool for peptide ligation“ led to a range of different ligation auxiliaries over the last two decades. Despite the intense research in this field established Nα-auxiliaries remained limited to glycine-containing ligation sites. Furthermore, the application of frequently used acid-labile Nα-auxiliaries requires strong acids or superacids to remove the auxiliary after the ligation reaction. Under these harsh acidic conditions the cleavage of the established amide bond has been observed as an undesired side-reaction. This work describes the synthesis of eight Nα-auxiliaries and their application in extended native chemical ligation. Six helping molecules were identified enabling auxiliary cleavage under mild-basic conditions. Perhaps most important and in contrast to previously reported Nα-auxiliaries, the 2-mercapto-2-phenethyl group facilitated access to sterically demanding ligation sites, beyond glycine. The synthetic utility of the auxiliary was demonstrated by the chemical total synthesis of two antimicrobial peptides. The application of a 13C-labelled scaffold allowed a detailled study oft the radical auxiliary cleavage reaction by NMR-spectroscopy. Additionally, the 2-mercapto-2-phenethyl auxiliary was utilised for a novel method of chemical protein synthesis, which delivered the desired proteins without a single HPLC-purification in high purity. Finally, a selenol-functionalized Nα-auxiliary is described for the first time by introducing the 2-selenol-2-phenethyl mojety. This scaffold enabled execptionally rapid peptide ligations and is readily removed with high selectivity.

Full textNative chemical ligation continues to lead as the method of choice for the total chemical synthesis of proteins. Despite the methods broad use the method requirement for a terminal cysteine residue remains its biggest disadvantage. N-alpah-auxiliaries have long been used to overcome this inherent hindrance by acting as cysteine mimics. The method however has still not achieved broad use due to several key issues. In the first part of the thesis a new class of N-alpha-auxiliaries is presented. The auxiliaries are straightforwardly synthesized, readily introduced onto the peptide building blocks and cleaved under mild basic conditions. Model tests were carried out to evaluate the auxiliaries’ characteristics and their removal chemistry was developed. Finally, the auxiliary was utilized for the synthesis of the antimicrobial C-terminal domain of Dermicidine. Solid phase chemical ligation has grown in popularity in the recent years. Benefitting from the solid-phase inherent purification characteristic it allows for multiple peptide fragments to be ligated in a sequential fashion to yield the full length protein target in high purity. In the second part of the dissertation the concept of solid phase chemical ligation is expanded beyond the cysteine junction using a “second generation” auxiliary. MUC1 protein variable tandem repeats domain was synthesized using auxiliary-assisted solid phase chemical ligation.

Full textEn la presenteinvestigación se estudia el desplazamiento auxiliar que ocurrió en el español, es decir, el proceso mediante el cual frente a la posibilidad de usar dos auxiliares para formar tiempos compuestos (ser y haber) hoy en día solo existe haber, siendo desplazado el auxiliar ser de esta finalidad. El estudio de este fenómeno está enfocado en comprobar/refutar la pertinencia de la Auxiliary Selection Hierarchy de Antonella Sorace (2000)para el caso del español, la cual plantea que el desplazamiento auxiliar se da ordenadamente y que los verbos con telicidad inherente fueron aquellos que más resisitieron el desplazamiento. Una de lasprincipales críticas que se realiza a la propuesta de Sorace es que las categorías con las que trabaja carecen de rasgos formales que las diferencien claramente. Debido a esto, también se toman otras dos teorías con las cuales se estudia el desplazamiento auxiliar: la de Vendler (1967) y la de Cuartero (2006) para el caso de los verbos de movimiento. El análisis se realiza con un corpus compilado por Rosemeyer (2016) de textos españoles datados entre los siglos XIII y XVII. Los resultados indican que en términos generales, la telicidad sí es un fenómeno que ordena el desplazamiento auxiliar. También fue posible concluir que la composicionalidad de la sintaxis y la aparición de la partícula se juegan un rol importante en el desplazamiento.

Full textAuxiliaries constituted one of the strongest sections of the Roman armies particularly during the Late Republic, although their development was never complete until the Early Empire when the overall reform of Rome’s institutions carried out by Augustus during his Principate finally adjusted. Modern studies on the imperial auxilia are relatively common and rich in their detailed analyses thanks to a generous amount of data, not only from the classical literature but also inscriptions and the archaeology from the imperial period. For instance, dozens of imperial auxiliary castra have been excavated, particularly in the Germanic limes and along the Hadrian's Wall, whose rich epigraphic findings have made us better understand the movements, organization and composition of several alae, cohortes and other imperial auxiliary units. However, all this said, we must remind ourselves that in the Republican era only a fraction of such information is available and a similar approach simply cannot be undertaken. This dissertation focuses on the non-Italian auxiliary forces within the last century of the Republic, 133-27 BC. Considering the source limitations noted above, efforts have been made to make use of literary, epigraphic, coin and archaeological data whenever possible. Nevertheless, in order to generate new perspectives of analysis several issues have been highlighted, such as the geographical and historical background from which these auxiliaries were deployed, the forms of recruitment and organization of such troops, and in particular the use of local and Roman coinages to pay and reward them. Accordingly, my work has been divided geographically into four main sections, each devoted to the historical background, recruitment forms and the Roman and local coin evidence for military pay in more specific regions. During the extreme turmoil detected throughout our period and which eventually destroyed the Republic both the legions and their auxiliary wings suffered major changes. Although later in the Empire divisions between them were clear, in the Late Republic and particularly during the core period of Civil Wars their limits blurred considerably. When extreme measures were required, irregular legions formed by non-citizens were to be conscripted, meaning that non-citizens actually integrated both the wings and the core of a Roman army. After the conclusions, written both in Spanish and English, a concise bibliography and an extensive graphic annex follow. Within this annex maps from every region discussed in the four preceding chapters have been included, as well as some graphs and illustrations complementing the archaeological data. Photographs and drawings of the coins are essential for better understanding the iconographic perspective of the numismatic analysis I propose to undertake throughout my study.

Full textSemi-auxiliary verb's role in modern French syntax and semantics is very significant because the semi-auxiliary verbs are quite frequent in literature as well as periodicals. All the linguists agree on the fact, that auxiliary verbs or pure modals do not contain any semantic meaning and serve just for grammatical purposes to express future or past times and semi-auxiliary verbs in French do contain some part of its semantic meaning and have some serious impact on the main verb. Linguists’ approaches differ only in the denomination as a semi-auxiliary or auxiliary of aspect, auxiliary aspect verbs, modal verbs, verbs compounds and so on. The semi-auxiliary verbs role consists of its semantic sens as well as its syntactic functions, as semi-auxiliary verbs tend to express the shadings of a verb, that can’t be translated by morphological means and morphological forms. On the syntactic point of view, semi-auxiliary verbs form with the infinitive an integrated combination of the predicate. It is an integral part of the predicate, where the semi-auxiliary acts as a regular verb under all rules of grammar: changes in accordance with person, singular or plural, gender, mode, time etc.
Le rôle du verbe semi-auxiliaire dans le français contemporain du point de vue sémantico- syntaxique est très important, puisque les verbes semi auxiliaires sont fréquents en belles lettres ainsi que les périodiques et le quotidien. Les approches des linguistes envers le verbe semi-auxiliaire ne diffèrent qu’en dénomination : semi-auxiliaire, auxiliaire d’aspect, les aspectuels, les modaux, causatifs, perceptifs, périphrases verbales etc. Tous les linguistes soulignent que le verbe auxiliaire est dépourvu de tout sens, et le verbe semi-auxiliaire en garde une partie sémantique plus ou moins grande. Les semi-auxiliaires aident à exprimer les nuances quand les formes morphologiques ne peuvent pas les couvrir. Le verbe semi-auxiliaire est étroitement lié à l’expression de l’aspect. Le rôle sémantique des verbes semi-auxiliaires consiste à apporter des nuances au verbe principal ou même détourner son sens, tandis que le rôle syntaxique est plus concret et consiste à précéder et faire partie intégrante du prédicat et .

Full textO presente estudo teve como objetivo central analisar o papel da Auxiliar da EducaÃÃo Infantil no contexto de Creche no municÃpio de Fortaleza. Contou com as contribuiÃÃes de diferentes autores. Inicialmente, ao revisitar a HistÃria da EducaÃÃo Infantil, buscando conhecer a gÃnese da docÃncia com crianÃas pequenas, utilizou-se das ideias de Vieira (1988, 1999), Arce (2001, 1997), Louro (1997), Rosemberg (1999, 2003a, 2003b, 2008), Kramer (2011a), Oliveira (2011a), Kuhlmann Jr. (2000, 2015), dentre outros. Estes estudiosos reforÃam a compreensÃo de que a atividade docente nesta etapa educacional nasce da prÃtica nÃo profissional, de um cenÃrio com pouco investimento financeiro, marcado por uma concepÃÃo educacional assistencialista e pelo mito da educadora nata. Em seguida, visando refletir sobre a docÃncia com crianÃas em Creches e PrÃ-Escolas a partir da inserÃÃo da EducaÃÃo Infantil na primeira etapa da EducaÃÃo BÃsica, considerando as especificidades das crianÃas pequenas, o paradigma do cuidado e da educaÃÃo e o professor como o profissional legitimado a atuar nesse cenÃrio, recorreu-se a Oliveira-Formosinho (2011, 2002), Duarte (2011), Martins Filho (2013), GonÃalves (2014) e Schmitt (2014). AlÃm disso, foram considerados importantes documentos de Ãmbito nacional e municipal, como a ConstituiÃÃo Federal (BRASIL, 1988), a Lei de Diretrizes e Bases da EducaÃÃo Nacional (BRASIL, 1996a), as Diretrizes Curriculares Nacionais para a EducaÃÃo Infantil (BRASIL, 2009a) e a ResoluÃÃo Municipal n 002/2010 (FORTALEZA, 2010). A fim de compreender o fenÃmeno enfocado, optou-se pela realizaÃÃo de uma pesquisa de abordagem qualitativa (BOGDAN; BIKLEN, 1994), com algumas caracterÃsticas de um Estudo de Caso (LÃDKE; ANDRÃ, 1986; GIL, 2008). Para a geraÃÃo de dados (GRAUE; WALSH, 2003) foram realizadas a aplicaÃÃo de questionÃrio com as Auxiliares, seÃÃes de observaÃÃo participante e entrevistas individuais com os sujeitos da pesquisa, professoras e coordenadora da instituiÃÃo investigada. A anÃlise dos dados, dentre outros aspectos, revelou: 1) um grupo profissional docente heterogÃneo e admitido de forma diferenciada; 2) que o trabalho cotidiano das Auxiliares consiste em prÃticas de cuidado e educaÃÃo dirigidas Ãs crianÃas, mas, apesar disso, nÃo à percebido como prÃtica docente, como aÃÃo âpedagÃgicaâ e 3) uma percepÃÃo da Auxiliar como profissional importante no contexto da EducaÃÃo Infantil, dadas Ãs tarefas que desenvolve, mas que à vista como profissional responsÃvel pelo âcuidadoâ, tratando-se de uma funÃÃo complementar ao papel âpedagÃgicoâ das professoras. Os achados desta pesquisa apresentam uma EducaÃÃo Infantil acometida pela âmaldiÃÃo de SÃsifoâ (ROSEMBERG, 2003b) e apontam a urgÃncia de revisÃo dos elementos que constituem a docÃncia com crianÃas pequenas, especialmente, na rede pÃblica do municÃpio pesquisado.
The present study had as main objective to analyze the role of the Auxiliary of Infant Education in the context of Day Care in the city of Fortaleza. To support this study, the theoretical basis was based on different authors. Initially, when revisiting the History of Early Childhood Education, seeking to know the genesis of teaching for young children, the ideas of Vieira (1999, 1988), Arce (2001, 1997), Louro (1997), Rosemberg (1999, 2003a, 2003b, 2008), Kramer (2011a), Oliveira (2011a), Kuhlmann Jr. (2000, 2015), among others, revealing that the teaching activity in this sector was born from non-professional practice, marked by the assistance and the myth of the cream educator. Next, it was reflected on teaching for young children from the insertion of Early Childhood Education in the first stage of Basic Education, considering the paradigm of care, the specifics of small children and the teacher as a professional legitimized to work in this sector. For this, authors such as OliveiraFormosinho (2002, 2011), Duarte (2011), Martins Filho (2013), GonÃalves (2014) and Schmitt (2014) have proved fundamental to weave such reflections. In addition, important national and municipal documents were considered, such as the Federal Constitution (BRASIL, 1988), the Law on Guidelines and Bases of National Education (BRASIL, 1996a), the Curriculum Guidelines for Early Childhood Education (BRASIL, 2009a) and Municipal Resolution n. 002/2010 (FORTALEZA, 2010). In order to understand the focused phenomenon, a qualitative approach was chosen (BOGDAN; BIKLEN, 1994), having as a methodological strategy the Case Study (LÃDKE; ANDRÃ, 1986; GIL, 2008). For data generation (GRAUE; WALSH, 2003), a questionnaire was applied with the Assistants, participant observation sections and individual interviews with the research subjects, teachers and coordinator of the research institution. Data analysis, among other aspects, revealed: 1) a heterogeneous professional group, with or without qualification for differentiated teaching and admission; 2) found that the Auxiliaryâs daily work consists of care and education practices directed at children, but nonetheless, it is not perceived as a teaching practice, as a âpedagogicâ action; 3) a perception of the Auxiliary as an important professional in the context of Early Childhood Education, due to the tasks they carry out, but, as supposed to be a developer of âcareâ and âteaching supportâ practices, being therefore a complementary function to the âpedagogicalâ of the teachers. Thus, the findings of this research present a Child Education undertaken by the âCurse of Sisyphusâ (ROSEMBERG, 2003b) and which presents the urgency of reviewing the elements that constitute teaching for young children and point out the urgency of reviewing the elements that constitute teaching with young children, especially in the public network of the municipality surveyed.

A proposta dessa pesquisa é investigar os fenômenos de Reestruturação e auxiliaridade verbal no PB. Ambos envolvem aplicação de regras sintáticas que desencadeiam a formação de predicado complexo, formando uma sequência verbal na estrutura de superfície. Com base em autores como Rizzi (1982), Aissen e Perlmutter (1983), Burzio (1986), Gonçalves (1999, 2001) e Cinque (2006), caracterizamos o fenômeno da Reestruturação, apresentando suas diferentes versões. Os verbos desencadeadores da regra de Reestruturação selecionam um complemento VP/infinitivo, gerúndio, particípio ou um P InfP. Este deve, entretanto, ser transparente para determinados fenômenos linguísticos locais. Objetivamos também depreender, dentre os verbos de Reestruturação, os genuinamente auxiliares. Ambos permitem o movimento (longo) do objeto, impossibilitam a dupla negação, subcategorizam um VP dependente temporalmente do domínio matriz e estão sujeitos à ordem relativa dos núcleos funcionais. Constatamos, entretanto, que é próprio dos auxiliares não imporem restrições semânticas ao seu complemento, ocorrerem com sujeitos de expressões idiomáticas, sofrerem o fenômeno da transparência de voz, não serem suscetíveis à apassivação e, por fim, seguirem rigidamente a hierarquia de núcleos funcionais proposta por Cinque (2006). Os verbos que submetemos aos testes determinantes dos fenômenos de Reestruturação e de Auxiliaridade verbal foram os modais (poder, dever, ter de/que), os aspectuais (começar, tornar, voltar, continuar, acabar, terminar, parar), os verbos de movimento (ir, vir) e os verbos ter, haver e estar. Os resultados mostraram que esses verbos se comportam diferentemente em relação a cada um dos fatores investigados, revelando estarem em estágios diferentes de gramaticalização. Com base em nossos resultados, apresentamos uma hierarquia parcial de núcleos funcionais do PB. Esta coincidiu com a proposta por Cinque (2006, p. 12; 93) para as línguas românicas na maioria dos aspectos. As diferenças se restringiram praticamente às posições previstas para os núcleos aspectuais com ênfase nos aspectuais inceptivo e completivo. Para o autor, estes remetem a mais de um núcleo funcional na hierarquia, o que explicaria suas diferentes possibilidades de ordenamento em relação a outros verbos funcionais. Na nossa proposta, entretanto, os aspectuais se comportam como os demais verbos, correspondendo a um único núcleo funcional. A sua assistematicidade na ordem revela um estágio menos avançado de gramaticalização que o dos modais e dos verbos de movimento, que seguem rigidamente o ordenamento proposto na hierarquia.

Full textThe Bayesian inference is getting more and more dependent of stochastic simulation algorithms, and its efficiency is directly related with the efficiency of the considered algorithm. The introduction of auxiliary variables is a technique widely used for attainment of the full conditional distributions, which facilitate the implementation of the Gibbs sampling. However, the introduction of these auxiliary variables can produce algorithms with simulated values highly correlated, this fact harms the convergence. The grouping of the unknow quantities in blocks, in such way that the joint simulation of this quantities is possible, is an alternative for reduction of the autocorrelation, and therefore, improves the efficiency of the simulation procedure. In this work, we present proposals of simulation using the Gibbs block sampler in the context of binary response regression models using auxiliary variables. Three class of links are considered: probit, logit and skew-probit. For the two first we present and implement the scheme of joint update proposed by Holmes and Held (2006). For the skew-probit, we consider four different ways to construct the blocks, and compare these algorithms through two measures of efficiency (the average Euclidean update distance between interactions and effective sample size). We conclude that the considered algorithms are more efficient than the conventional (without blocks), where one of these leading to around 160\\% improvement in the effective sample size. Moreover, we discuss one important stage of the modelling, called residual analysis. In this part we adapt and implement residuals considered in the probit model for the logistic and skew-probit models. For a simulated data set we detect the presence of outlier used the residuals proposed here for the different models.

Full textIn this dissertation, we offer an analysis of the verb acabar and some sentences in which it can figure according to the formal linguistics. We investigate the syntactic-semantic characteristics of these sentences and try to identify what kind of syntactic structure best represents them. Travaglia (2004b) discusses the poligrammaticalization of the verb acabar and shows that this verb is grammaticalizing in different ways. This author shows seven grammar values in different levels of grammaticalization for this verb, besides its meaning as a lexical verb. We suggest a reduction of these eight possibilities to interpret acabar into five, since four examples analysed in different ways by that author seems to allow a same reading. In the sentences we analyse in this dissertation, we reduce the scope of our investigation only to the verb acabar that brings an idea of an event result or final phase, bringing a reading like: something happened and, by the end, the situation ended up like this. Many tests were done to define this verb as an auxiliary or aspectualizer, but these tests dont show the same results. We observe that acabar dont exhibit an uniform behaviour, sometimes working as an auxiliary verb, other times as an apectualizer. In spite of the great range of characteristics that we observe for this verb behaving as an auxiliary, we consider it an aspectualizer (following Wachowicz (2005, 2007)), mainly due to the way it works over the time interval expressed by the main verb, restricting this interval to its final phase or to its result, that is a strong characteristic for the aspectualizers, according to Lunguinho (2005, 2009) and Wachowicz (2005, 2007). This verb shows all raising characteristics according to the tests proposed by Davies & Dubinsky (2004). The verb acabar is selecting a proposition in all of the examples in focus on this dissertation, a small clause, and the logical subject of the predicate in the nucleus of this small clause raises to a superficial subject position. The verb acabar works as an unnacusative verb, selecting only one internal argument, in this case, a SC. Ferreira (2009) assumes that an unnucusative verb behaves as a raising structure. This author considers auxiliaries as a subgroup of the unnacusatives, and the later verbs, as a subgroup of the raising verbs. For this reason, we assume that acabar is in crossroads between unnacusative verbs subgroup that selects a SC, a CP, a DP and the auxiliary verbs, since it shows some characteristics of these verbs. We compare the properties of acabar with some properties of passives in natural languages, as discussed in Jaeggli (1986). Two of the three properties of passives in natural languages are also the properties of unnacusative verbs and, consequently, of raising verbs: i) the NP in the subject position doesnt receive a -role; and ii) the NP in the position of VP doesnt receive structural Case. So, these properties are true not only for the passives, but also for the verb acabar, but in different ways. Then, these constructions can have the same reading, but not the same syntactic structure. It is possible to establish a relation between these passive sentences and the raising structures in which acabar can occur, in spite of the fact that auxiliary verbs and unnacusatives present properties of raising verbs, as discussed in Ferreira (2009). Besides, passives can present some characteristics common to that constructions. Then, we get a similar reading to all of these constructions.

Full textThis dissertation presents research across the main types of verb-phrase anaphora involving DO, viz. do this/that/it anaphora, do so anaphora, post-auxiliary ellipsis (PAE) and British English DO. Each anaphor underwent close analysis based on a sample of several hundreds of occurrences retrieved from the BNC and the COCA, as well as Bos & Spenader's (2011) corpus. Different variables were studied including register, the grammatical status of DO, semantic and syntactic properties of antecedent triggers, identity of subjects and states of affairs, the presence or absence of contrastive and non-contrastive adjuncts, as well as polar, modal, aspectual, temporal and voice alternations.One item of particular interest involves British English DO which bears a strong resemblance to PAE, except that it involves non-finite forms of DO and is generally restricted to British conversational English. Unlike PAE, British English DO has never before been the focus of study based on empirical data. In this research, 483 naturally-occurring examples taken from the Spoken component of the BNC as well as the accompanying metadata and recorded material were fully examined. Sociolinguistic and situational information was investigated, as were the linguistic properties and discourse conditions that make the use of British English DO felicitous. The result has led to a far better understanding of the phenomenon.

A globalização tem causado um aumento significativo na competição entre as empresas, mas em contrapartida ela também permite a cooperação entre empresas, mesmo que estejam geograficamente distantes umas das outras. Uma área de pesquisa decorrente dessa aproximação virtual é a fabricação de peças a distância, que conta com a participação dos seguintes atores: (i) um cliente remoto que introduz as encomendas; (ii) uma empresa modeladora responsável pelo desenvolvimento e disponibilização de módulos computacionais para o projeto das peças e para o planejamento das operações de manufatura; e (iii) uma empresa onde a fabricação propriamente dita será efetuada. No presente trabalho de Mestrado descreve-se o desenvolvimento de um sistema computacional visando a integração CAD/CAPP/CAM para a fabricação a distância de peças prismáticas via Internet. O módulo CAD é baseado na abordagem de projeto por features, onde um cliente remoto pode modelar a peça para logo depois enviar a ordem de fabricação para o servidor. O módulo CAPP recebe as informações vindas do CAD e adiciona dados relativos à manufatura, gerando então o plano de processo. Finalmente, de posse das informações acima, o módulo CAM gera o programa para a usinagem da peça e o envia para a máquina. Os resultados deste sistema são testados em uma máquina de prototipagem rápida por usinagem. O sistema computacional foi baseado nas técnicas de programação orientada a objetos. Globalization has been causing a significant increase in the competition among companies, but on the other hand it also allows the cooperation between companies, even if they are geographically distant among themselves. A research area due to that virtual approach is the remote manufacture of parts, which has the participation of the following actors: (i) a remote customer who inputs the orders; (ii) a modeling company, who is responsible for the development and provision of software modules for the design of the parts and for the manufacturing process planning; and (iii) a company where actual manufacture will take place. In the present Master's research the development of a software system is described aiming at the integration of CAD/CAPP/CAM for the remote manufacture of prismatic parts through the Internet. The CAD module is based on the features approach, where a remote customer models the part and then sends the production order to the server. The CAPP module receives the information from the CAD module, and adds manufacturing data to it, generating the process plan. Finally, after getting hold of the above information, the CAM module generates the program for the machining of the part and sends it to the machine. The results of this system are tested in a rapid prototyping machine (by machining). The software system was developed based on the object-oriented programming technique.

Full textThe aim of this project is to develop an auxiliary office chair, which favorably will compete with
the existing chairs on the market. Evolutions of ergonomical survey in the work environment and
on the configuration of offices require new products which fulfill the requirements properly.
In order to achieve it a survey about office chairs has been carried out: types, characteristics, ways
of usage and products on the market besides a large antropometrical study and ergonomics related
to work area study.
The result is an auxillary office chair which improves significatively in ergonomics compared with
such chairs found in the market survey.
Moreover it is achieved a great improvement refering to apilability stackable characteristics and
manufacturing, as this chair has good features as easily cleanning and innovative aesthetics and no
high manufacturing cost. That means an easily marketed product.

After deprotection, very synthetically useful enantiomerically pure compounds were obtained.An acces to chiral trifluoromethylated pyrrolidines was developped starting from trans-Fox. The trans 2-phenyl-5-trifluoromethylpyrrolidine was used as a chiral auxiliary for asymmetric alkylation reactions

Full textAMPA type glutamate receptors (AMPARs) are ionotropic receptors responsible for most excitatory transmission in the central nervous system. The number of stabilized AMPARs in front of glutamate release sites determines in large part the strength of synaptic transmission and variation in this number is thought to underlie numerous forms of synaptic plasticity. AMPARs are present in three main subcellular pools between which they are in a dynamic equilibrium by processes of trafficking: intracellular receptors, extrasynaptic receptors, and synaptic receptors stabilized at the postsynaptic density (PSD). Transmembrane AMPAR regulatory proteins (TARPs) are known to be implicated in AMPAR stabilization at the synapse through the interaction of TARP γ-2/8 with the scaffolding protein PSD-95. In the hippocampus, a structure exhibiting various synaptic plasticity patterns, γ-8 is the most abundant TARP. This isoform is characterized by a longer C-terminal fragment than γ-2 and a synaptic and extrasynaptic localization. During my Ph.D, I studied the molecular mechanisms involved in the regulation of TARP γ-2 and γ-8 binding to PSD-95 and their respective roles in regulating AMPAR lateral mobility. The main results are: a) γ-2 interaction with PSD-95 is regulated by the apparent length of its C-terminus domain that is modulated by phosphorylation; b) γ-8 binds PSD-95 in synaptic and extrasynaptic compartment however this interaction is not correlated with AMPAR immobilization. Altogether, those results suggest that those two TARP isoforms have independent functional roles

finalidade desse estudo é avançar no entendimento da importância de se integrar ferramentas eletrônicas já disponíveis, de forma eficaz, na organização, da situação de ensino-aprendizagem em uma sala de aula. Teorizações do campo da didática, da pedagogia, da comunicação e da tecnologia educacional embasam as reflexões e as constatações levantadas na parte empírica desse trabalho, centrada em duas escolas públicas com oferta de ensino fundamental. A partir dos dados, informações e observações realizadas foram identificados alguns aspectos e caminhos já percorridos nesse processo e as possibilidades de dinamizá-lo, estendendo o emprego da televisão associada ao computador na sala de aula como uma ação didática significativa no atual contexto, que deve orientar a prática docente a partir de uma lógica, que deve considerar a multidimensionalidade no processo de ensino-aprendizagem. As questões constatadas dão ênfase à ciência do professor sobre a sua preparação insuficiente para o trato com as novas linguagens, à motivação e entusiasmo dos alunos que reclamam por mais contato com os recursos eletrônicos existentes, à legitimidade da Escola e ao papel insubstituível desse professor na difusão do conhecimento. Chegou-se a conclusão que a mediação mais institucional da Escola, uma perspectiva a longo prazo em relação às mudanças, o apoio contínuo aos professores que inovam e experimentam, a oportunidade para a troca de experiências e informações entre os professores e a participação ativa dos alunos em atividades curriculares relevantes, são procedimentos que devem estar sempre presentes e articulados e que melhor podem balizar o processo de incorporação de ferramentas didático-eletrônicas na sala de aula.

A ação dos instrumentos nas paredes do canal radicular proporciona a formação da camada residual, que é um extrato de matéria orgânica e inorgânica, de aparência amorfa, superfície irregular e granulosa que é depositada na superfície dentinária a medida que vai se formando, e quando não é removida pode interferir no selamento almejado na etapa da obturação. Algumas substâncias químicas com diferentes composições e variadas concentrações são utilizadas isoladas ou em associações para remover esta camada residual. O presente estudo buscou analisar in vitro, através de Microscopia Eletrônica de Varredura, a eficácia na remoção da camada residual, de diferentes formulações de Endo PTC quando associadas a diferentes concentrações de hipoclorito de sódio, utilizando ou não, irrigação final com EDTA. Para tanto, foram utilizados oitenta dentes unirradiculares humanos recém-extraídos, divididos aleatoriamente em oito grupos de dez dentes cada e distribuídos de acordo com as substâncias utilizadas na instrumentação, da seguinte maneira: Grupo I – preparo do canal com Endo PTC creme, associado ao hipoclorito sódio a 1%; Grupo II – preparo do canal como Endo PTC creme, associado ao hipoclorito de sódio a 2,5%; Grupo III – preparo do canal com Endo PTC creme associado ao hipoclorito de sódio a 1% e irrigação final com EDTA a 17%; Grupo IV – preparo do canal com Endo PTC creme associado ao hipoclorito de sódio a 2,5 e irrigação final com EDTA a 17%. Nos Grupos V, VI, VII e VIII foram utilizadas as mesmas substâncias dos grupos I, II, III e IV respectivamente, substituindo o Endo PTC creme pelo Endo PTC Leve. Os resultados mostraram que: a irrigação final com EDTA promove uma melhor remoção da camada residual, independente da concentração do hipoclorito de sódio e da formulação do Endo PTC; de um modo geral as formulações do Endo PTC não apresentam diferenças estatisticamente significantes na remoção da camada residual independente da concentração do hipoclorito de sódio; a concentração do hipoclorito de sódio associado ao Endo PTC creme, não interfere estatisticamente na remoção da camada residual; a concentração do Hipoclorito de sódio associado ao Endo PTC Leve apresentou diferença estatisticamente significante quando foi feita a irrigação final com EDTA, sendo que a 2,5 % apresentou melhores resultados; no terço apical quando foi utilizado hipoclorito de sódio a 1% e foi feita irrigação final com EDTA, a remoção da camada residual foi estatisticamente inferior ao terço cervical independente da formulação do Endo PTC.

A torta de filtro apresenta bagaço residual oriundo do processo de extração do caldo de cana-de-açúcar e quando armazenada por longos períodos, se torna um habitat ideal para o desenvolvimento de comunidades microbianas que atuam na desconstrução da lignocelulose. Nossas análises de dados de sequenciamento de DNA metagenômico sugerem que a torta de filtro armazenada por 40 dias possui uma microbiota com características funcionais e ecológicas exclusivas em relação a outros ambientes com elevada disposição de material lignocelulósico. Assim como em ambientes de compostagem, os filos mais abundantes são Actinobacteria, Proteobacteria, Firmicutes e Bacteroidetes. Dentre os principais genes que estes micro-organismos possuem, estão Glicosiltransferases, Carboidrato Esterases e Glicosil Hidrolases, que atuando em conjunto, são passíveis de desconstruírem a lignocelulose e participarem na liberação de açúcares menores, ácidos orgânicos e outros nutrientes. Neste trabalho, identificamos novas enzimas da família AA10 que oxidam a celulose cristalina, demostrando o potencial deste ambiente em possibilitar a adaptação de micro-organismos que expressam enzimas capazes de desestruturar a celulose altamente condensada, possibilitando a liberação de moléculas de glicose. A comunidade microbiana pode acessar nutrientes como Fósforo e Nitrogênio através da despolimerização da biomassa vegetal ou decomposição da microbiota morta. No ciclo biogeoquímico do nitrogênio, a evaporação de amônia é reduzida pela assimilação desta substância pela comunidade microbiana, sendo que a amônia é produzida pela via de amonificação de nitrato e nitrito. Outro ciclo biogeoquímico identificado na torta de filtro foi o do carbono, ocorrendo diminuição da emissão de metano e gás carbônico devido ao uso destas moléculas no metabolismo microbiano. Por apresentar muitas espécies de micro-organismos termofílicos e funções ecológicas similares a compostagens que alcançaram fase termofílica, a torta de filtro armazenada por 40 dias não aparenta conter micro-organismos patogênicos em elevada abundância, o que poderia ser um indício de sua segurança biológica se usado como adubo no solo. No entanto, recomenda-se que novos estudos sejam realizados neste tipo de ambiente agrícola, afim de avaliar como se comportam principalmente os fungos Neosartorya fumigata e Paracoccidioides brasiliensis, os quais são identificados como agentes patogênicos mas que também são encontrados vivendo na natureza como organismos saprofíticos e em interação com alguns mamíferos, sem causar doença.
The filter cake presents residual bagasse from the process of extracting the sugarcane juice and when stored for long periods, it becomes an ideal habitat for the development of microbial communities that act in the deconstruction of lignocellulose. Our analyzes of metagenomic DNA sequencing data suggest that the filter cake stored for 40 days has a microbiota with unique functional and ecological characteristics compared to other environments with high lignocellulosic material. Thus in composting environments, the most abundant phyla are Actinobacteria, Proteobacteria, Firmicutes, and Bacteroidetes. Glycosyltransferases, Carbohydrate Estersases and Glycoside Hydrolases, which act together, are capable of deconstructing lignocellulose and participate in the release of smaller sugars, organic acids and other nutrients. In this work, we identify new enzymes of the AA10 family that oxidize crystalline cellulose, demonstrating the potential of this environment to enable the adaptation of microorganisms that express enzymes capable of destabilizing highly condensed cellulose, allowing the release of glucose molecules. The microbial community can access nutrients such as Phosphorus and Nitrogen through the depolymerization of the plant biomass or decomposition of the dead microbiota. In the biogeochemical cycle of nitrogen, the evaporation of ammonia is reduced by the assimilation of this substance by the microbial community, and ammonia is produced by ammonification of nitrate and nitrite. Another biogeochemical cycle identified in the filter cake was that of carbon, with a decrease in the emission of methane and carbon dioxide due to the use of these molecules in microbial metabolism. Because it contains many species of thermophilic microorganisms and ecological functions similar to composting that reached the thermophilic phase, the filter cake stored for 40 days does not appear to contain pathogenic microorganisms in high abundance, which could be an indication of its biological safety if used as soil fertilizer. However, it is recommended that new studies be carried out in this type of agricultural environment, in order to evaluate the behavior of the fungi Neosartorya fumigata and Paracoccidioides brasiliensis, which are identified as pathogens but are also found living in nature as saprophytic organisms and in interaction with some mammals, without causing disease.

Full textThis dissertation addresses the problem of improving the teleoperation experience of an overconstrained multiterrain mobile robot. Localising a robot and assessing its condition is cumbersome in a teleoperation scenario. Despite the fact that robots are becoming more sophisticated,they aren’t still able to perform efficiently without human intervention. Current state of the art localisation technology is not able to operate without failure. Odometry is robust, though it is error prone and complicated to use in over-constrained robots. Ideally, every actuator drives the robot to the same position, though, terrain roughness difficults the task of motion control systems which fail to guarantee perfect kinematic geometries. This means that each wheel contributes differently to the position estimation of the robot. The proposed odometry model considers the input provided by each wheel and provides an error model for further sensor fusion. The operator’s link to the remote environment is often influenced by a single video feed which decreases the operator’s capability of assessing the robot’s condition. This contributes to disorientation and complicates the comprehension of the remote environment. This dissertation tackles the problem of improving situation awareness in teleoperation by offering the user multiple alternatives to control a pan-tilt camera. Results obtained in real and simulated environments demonstrate the capabilities of the presented systems.

Full textThis dissertation aims to deal with some particular questions about ius militare, namely the specific ius singulare, which regulated the condition of Roman soldiers and veterans from the age of Augustus. In particular, the study focuses solely on the rules regulating the condition of milites and veterans in the period of the Roman Principate. The research is divided into four parts. In the first part there is a short description of the institutional history of the Roman army, from the reform of Caius Marius up to the interventions of Augustus in military affairs. With regard to the Augustan military reform, I have concentrated first on the creation of the professional military service and, secondly, on the foundation of the awards of discharge (the so-called praemia militiae) and of the aerarium militare (namely the treasury that would specifically finance the praemia). In the second part, I examine the rules pertaining to the procedure of recruitment and the conditions of access to the different units of the Roman army, namely the legions, the auxiliary units, the Praetorian Guard, the urban cohorts, the vigiles, the equites singulares Augusti, and the praetorian and provincial classes. In addition to the physical and legal requirements, necessary for access to these units, I examine in depth the status civitatis that was conferred to the milites of some units (in particular the classiarii of praetorian classes and the equites singulares Augusti), at the moment of their enrolment in the military. The third part examines a very controversial issue, namely the marriage ban for the soldiers. Following a detailed examination of the different opinions on this question, my dissertation investigates some complex issues which are still to be resolved, clarifying that the ban, certainly introduced befor Claudius, was withdrawn only by Septimius Severus in 197 AD. Furthermore, the research deals with two other related matters: namely, the legal status of the relationships maintained by the soldiers with the women that they met during the service, and, the condition of the children conceived in these relationships. As far as the latter is concerned, I particularly concentrate on the content of the well-known epistula of Hadrian to Ramnius Martialis, which conferred to the children of some milites (in particular those of the legionaries) the bonorum possessio unde cognati. In the fourth and last part, I examine the issue of the privileges conferred to the veterans and their families upon discharge. The research focuses on the analysis of the formularies of diplomata militaria, namely the documents delivered upon the honesta missio (the honorable discharge) to the auxiliares, to the classiarii of the praetorian and provincial fleet, to the praetorians, to the urbaniciani and to the equites singulares Augusti. The examination of their formularies has allowed us to clarify the specific legal condition of the veterans from these different military units. Furthermore, the study on diplomata proposes other thorny questions: firstly it must be understood why they, apart from some exceptional cases, were never delivered to the veterans of iustae legiones. The dissertation ends with a research on the legal nature of the so-called leges veteranorum, namely the constitutiones on the basis of the delivery of each diploma. In this regard, the study attempts to identify the reason why the leges veteranorum concerning the auxiliaries, the classiarii, and the equites singulares Augusti, are different from those of the praetorians and of the urbaniciani, also as regards their diplomatic structure.

Resumo: O presente texto tem como objetivo caracterizar, no âmbito da profissão docente, a atividade de professoras auxiliares, eventuais e substitutas. Para tanto, optamos por evidenciar o discurso dessas professoras, através de entrevistas e/ou respostas fornecidas em um questionário escrito. Pesquisamos como essas professoras vivenciam a experiência docente e como a coordenação pedagógica entende essa função no contexto da instituição escolar. Assumindo uma perspectiva histórico-cultural, procedemos a uma análise dessas falas e escritas, destacando elementos que emergiram nos relatos pessoais e que se tornaram significativos à luz dos estudos psicológicos para compreender o trabalho e a (des)profissionalização dessas docentes
Abstract: The objective of this text is to characterize the activities of part-time and substitute teachers and also those of teaching assistants. For this, we chose to use these teachers¿ own words as evidence, through interviews and/or answers provided to a written questionnaire. Our research was focused both on how these teachers experienced their profession, and on how the pedagogical coordinators understood the function of these individuals, in the context of a school institution. Taking a historical-cultural perspective, we went on to analyze this spoken and written language, highlighting elements which emerged in the personal accounts. In the light of psychological studies, these elements became significant to enable a fuller understanding of not only their work, but also the (de)professionalization of these members of the teaching staff

Full textThis study took as object the transformations occurred in working, living and specially in the thinking and acting way of nursing attendants after their qualification as nursing auxiliaries through the LSP (Large Scale Project). It utilized work and qualification as analytical categories. The aim was to evaluate the dimension of the changes occurred with attendants after de qualification process. Study subjects were attendants who have qualified as auxiliaries through LSP, conducted by the Regional Health Administration 5 (São Paulo city), during 1990 a 1992. Life histories were used as a methodological tool to apprehend these transformations. The analyses allowed the recognition of both potentialities and limitations of the qualification process. Qualification have guarantied to the attendants: a) access to improved remuneration, promotion to a professional status e some working rights; b) conquer of some citizen rights not directly related with social rising; c) change in knowledge patterns; d) a certain autonomy related to technical aspects of health attention; d) gains in the humanization of care. The qualification process seems to have a relative power to modify the quality of health attention, allowing a certain understanding of the object of the health work and dominating technologies used in the working process. Nevertheless, it does not seems to constitute changes in the individual and clinical model of health assistance, showing a certain fragility to apprehend the political dimension proposed by the LSP to qualify health workers

Full textThe resources for the payment of health professionals represent a major part of total expenses of the public health services. Having adequate workforce for each task is very important to avoid over and under utilization of resources and many tasks in Dentistry can be done for auxiliaries. However, in Brazil, there are no study on the influence of dental auxiliaries on dental team productivity. The aim of this paper was to assess association between changes in the rates of dentistry professionals and dental infrastructure in public health services with changes in rates of dental procedures between the years 2008/2009 and 2014/2015. This an exploratory longitudinal ecological, including all 5,570 Brazilian municipalities, with 2008 as the starting point and final 2015. Secondary data from DATASUS and the Atlas of Human Development were collated. The outcome variables were: Group 1 procedures, consisting of the monthly rate of procedures attributable to dental assistant per 1000 inhabitants, Group 2 procedures, monthly rates attributable to dental hygienists per 1000 inhabitants and Group 3 procedures, monthly rates due to procedures exclusive to the Dentist per 1000 inhabitants. Outcome variables were controlled by demographic and socioeconomic data. The increase of dental assistant rate was associated with an increase in Group 2 (OR = 1.40, 95% CI: 1.20-1.63) and Group 3 (OR = 1.44, 95% CI: 1.24-1.67). The increase in dental hygienists was related both to the increase and decrease in Group 1 and 2 procedures. The increase in the rate of dental chairs was associated with an increase in Group 2 procedures (OR = 1.18, 95% CI: 1, 00-139). This study has a national representation on the influence of human resources and infrastructure in dentistry on the productivity of the oral health team. In view of the results, it is suggested that dental assistant could be hired by managers and professionals who wish to increase the production of the procedures of these two groups and also to carry out researches in order to clarify the effect of oral health technician rates on dental productivity.

Full textThe aim of this in vitro study was to evaluate antimicrobial activity of four auxiliary substances against Enterococcus faecalis, Staphylococcus aureus and Candida albicans, commonly isolated microorganisms in endodontic failure cases, on which was tested: 2% chlorhexidine gel (CHX), 2% Uncaria tomentosa gel (UG), 2% CHX gel and UG in equal parts (1:1) (CHX + UG) and Natrosol (NAT). Firstly, the agar diffusion method was used; the inhibition halos were measured and significance was determined using ANOVA and Tukey`s test (p <0.05). The more effective auxiliary substance against E. faecalis and C. albicans was CHX + UG, followed by CHX and UG. Against S. aureus, CHX+UG had a similar effect to that shown by CHX and UG.The NAT group had not effect against any microorganism. Secondly was evaluating antimicrobial activity of auxiliary substances in infected dentin. It was used a total of 120 pre-molars, which were divided for each organism into 4 groups (n = 10). Microbiological samples were collected before the chemomechanical preparation (PQM) (S1), after PQM (S2) and after 7 days of intracanal medication (MIC) for each group (S3). The count of colony forming units (CFU/mL) was statistically analyzed by Kruskal-Wallis and Mann-Whitney test (p <0.05). In S2, all groups showed a significant reduction of CFU/mL compared with S1 In groups CHX, CHX+UG and UG there was no CFU/mL. In S3, specimens contaminated with E. faecalis of the CHX and NAT groups had significantly higher microbial load compared with S2, but CHX+UG group kept the value obtained in S2, similar to that obtained by UG group. Specimens contaminated with S. aureus and C. albicans of the CHX, CHX+UG and UG groups remained the negative values of S2. With results obtained it was concluded, that the association CHX+UG has the ability to inhibit microbial growth of E. faecalis and C. albicans higher than shown by CHX and UG. Against S. aureus, CHX and UG had a similar effect. It was also found that CHX, CHX+UG and UG were effective in disinfecting the canal after PQM, but only after 7 days the groups that received CHX+UG and UG as MIC, remained root canals free of CFU of E. faecalis. Thus, UG alone or in combination with CHX, was effective in disinfecting root canals.
O objetivo deste estudo foi avaliar, por meio de testes in vitro, o potencial antimicrobiano de quatro substâncias auxiliares sobre microrganismos comumente isolados nos casos de insucesso do tratamento endodôntico, Enterococcus faecalis, Staphylococcus aureus e Candida albicans; Foram testados: gel de digluconato clorexidina a 2% (CHX), gel de Uncaria tomentosa a 2% (UG), gel de CHX e UG a 2% em partes iguais (1:1) (CHX+UG) e Natrosol (NAT). Primeiramente foi utilizado o método de difusão em ágar. Os valores coletados pela mensuração dos halos de inibição foram analisados estatisticamente com ANOVA de um critério e o teste de Tukey (p<0,05). A substância auxiliar que mostrou-se mais efetiva sobre E. faecalis e C. albicans foi CHX+UG , seguida da CHX e UG. Frente a S. aureus, CHX+UG apresentou um efeito semelhante ao mostrado pela CHX e UG. O Grupo NAT não mostrou capacidade de inibição sobre nenhum dos microrganismos. A segunda parte do estudo visou avaliar a capacidade antimicrobiana das sustâncias auxiliares em dentina contaminada. Foi utilizado um total de 120 pré-molares inferiores distribuídos em 4 grupos para cada microrganismo (n=10). Foram feitas coletas microbiológicas antes do preparo químico-mecânico (PQM) (S1), após PQM (S2), e após 7 dias com medicação intracanal (MIC) (S3). A contagem das unidades formadoras de colônia (UFC/mL) foi analisada estatisticamente pelo teste de Kruskal-Wallis e teste de Mann-Whitney (p<0,05). Em (S2), todos os grupos apresentaram uma redução significativa de UFC/mL em comparação com S1. Nos grupos CHX, UG e CHX+UG não houve a presença de UFC/mL; para S3, os espécimes contaminados com E. faecalis dos grupos CHX e NAT apresentaram carga microbiana significativamente maior à apresentada em S2; porém o grupo CHX+UG manteve o valor obtido em S2, valor que foi semelhante ao obtido pelo grupo UG. Os espécimes contaminados com S. aureus e C. albicans dos grupos CHX, UG e CHX+UG mantiveram os valores negativos de S2, assim não apresentaram UFC/mL. Concluiu-se que a associação CHX+UG apresenta capacidade de inibição do crescimento microbiano sobre E. faecalis e C. albicans superior ao mostrado por CHX e UG. Frente a S. aureus, CHX e UG apresentaram efeito semelhante. Concluiu-se também que CHX, UG e CHX+UG foram eficazes na desinfecção do canal após PQM, porém após 7 dias só os grupos que receberam CHX+UG e UG como MIC, mantiveram os canais livres de UFC de E. faecalis. Assim, UG só ou em associação com CHX, se mostrou eficaz na desinfecção de canais radiculares.

The allylation reaction of allyl organometallic compounds with aldehydes promoted by Lewis acids in the presence of chiral auxiliaries are a kind of nucleophilic addition reaction to control the stereochemistry of the product. The (R) -BINOL and (S) -4-benzylthiazolidine-2-thione compounds are used as chiral auxiliaries in asymmetric synthesis, although the literature describing the application of the first allylation reaction in the presence of various Lewis acids, it was not employed in the presence of niobium pentachloride. For the second compound, its application is limited to the aldol reactions and their study on enantioselective allylation reactions of aldehydes in the presence of Lewis acids was not described in the main databases used in this research. Therefore, this study investigated the application of these two compounds as chiral inductors in addition reactions of allyl tri-n-butilestanana to aldehydes in the presence of Lewis acid such as NbCl5. To optimize the reaction conditions used the p-nitrobenzaldehyde and was found to influence the proportion of the reactants in enantioselectivity and reaction yields. It was observed that the best yields (between 63-65% using (R)-BINOL and 41-50% using (S)-4-benzylthiazolidine-2-thione) were obtained when ethyl ether is used as solvent one temperature of -15 °C. However, the best enantioselectivity using a chiral auxiliary (R)-BINOL was obtained when the reaction rose while stirring for 1 hour the reaction between (R)-BINOL and NbCl5, then adding the aldehyde and stirred for 30 minuitos using diethyl ether and methylene chloride at -15 °C and -75 °C temperature conditions. On the other hand, the best enantioselectivity using the chiral auxiliary (S)-4-benzylthiazolidine-2-thione was obtained when it was used NbCl5 Lewis acid followed by stirring the reaction for 10 minutes and addition of diethyl ether as solvent under the conditions -15 °C temperature.
As reações de alilação de aldeídos com compostos organometálicos alílicos promovidas por ácidos de Lewis na presença de auxiliares quirais são um tipo de reação de adição nucleofílica para o controle da estereoquímica do produto. O (R)-BINOL e a (S)-4-benziltiazolidino-2-tiona são compostos utilizados como auxiliares quirais em síntese assimétrica e embora a literatura descreva a aplicação do primeiro em reações de alilação na presença de vários ácidos de Lewis, o mesmo não foi empregado na presença do pentacloreto de nióbio. No caso do segundo composto, a sua aplicação se limita as reações aldólicas e o seu estudo em reações de alilação enantiosseletiva de aldeídos na presença de ácidos de Lewis não foi descrito nas principais bases de dados utilizados nesta pesquisa. Portanto, nesse trabalho investigou-se a aplicação desses dois compostos como indutores quirais em reações de adição de alil-tri-n-butilestanana a aldeídos na presença de NbCl5 como ácido de Lewis. Para otimizar as condições reacionais utilizou-se o p-nitrobenzaldeído e verificou-se a influência da proporção dos reagentes na enantiosseletividade e nos rendimentos da reação. Percebe-se que os melhores rendimentos (entre 63-65% utilizando o (R)-BINOL e 41-50% utilizando a (S)-4-benziltiazolidino-2-tiona) foram obtidos quando o éter etílico foi utilizado como solvente a uma temperatura de -15ºC. Porém, a melhor enantiosseletividade utilizando o auxiliar quiral (R)-BINOL foi obtida quando elevou-se o tempo reacional para 1 hora de agitação na reação entre (R)-BINOL e o NbCl5, seguida da adição do aldeído e agitação por 30 minuitos, utilizando éter etílico e cloreto de metileno nas condições de temperatura de -15ºC e -75ºC. Por outro lado, a melhor enantiosseletividade utilizando o auxiliar quiral (S)-4-benziltiazolidino-2-tiona foi obtida quando utilizou-se o ácido de Lewis NbCl5 seguido pela agitação da reação por 10 minutos e adição de éter etílico como solvente nas condições de temperatura de -15ºC.

Full textItalian passive form offers a variety of choices that are hardly comparable to those of French. Apart from the canonical form essere and Past Participle, there are also the forms with venire, andare, finire, rimanere, risultare, restare, stare. The objective of this work is to understand the use of essere, venire, andare, rimanere and restare, auxiliaries of the Italian passive form, and the function of the existence of such a diversity within the framework of the Lexicon-Grammar of Maurice Gross and Amr H. Ibrahim's Methodology of Analytical Defining Matrixes (ADM).The study develops through 10 chapters.The first part introduces the state of the art on the Italian passive and the description of the chosen five auxiliaries, according to the traditional description of linguists and grammarians. The following chapters are devoted to the description of each auxiliary and the comparison of their uses.The work concludes with the synthesis of the different characteristics of passive periphrases and considerations of an aspectual-temporal order with an attempt at systematization.The aim of this work is to prove that the said auxiliaries are rarely commutable and that each of them introduces different morpho-syntactic and aspectual restrictions

Estudo dos verbos auxiliares e a noção de Locução Verbal no Português Brasileiro (PB), aplicando os conhecimentos da Teoria Gerativa a fim de descrever o comportamento destes verbos no PB. Isso porque a Gramática Tradicional identifica de forma não suficiente a locução verbal e o verbo auxiliar. O estudo está centrado na Teoria de Princípios e Parâmetros da Gramática Gerativa, em que os verbos foram analisados de acordo com a estrutura argumental. Descrevemos o comportamento dos verbos auxiliares e concluímos que o auxiliar é um inacusativo que c-seleciona apenas um único tipo de complemento que é um XP encabeçado por um núcleo funcional que c-seleciona VP. Só pode conter verbo auxiliar funcional o encontro verbal que resulta de alçamento.

Full textDeltaretroviruses include bovine leukemia viruses (BLV) and primate Tlymphotropic viruses (PTLV-1, -2, -3 and -4) which are composed of human Tlymphotropic (HTLV-1, -2, -3 and -4) and of their simian counterparts (STLV-1, -2, -3 and -4). PTLV-1 and BLV are the only ones associated to pathologies: a lymphoproliferative disorder named ATLL in humans and non human primates and a neurological disorder named HAM/TSP in humans in the case of PTLV-1 and a Bmalignant lymphoproliferation in BLV infected cattle. HTLV-2 has not been associated with any disease so far and the pathogenic potential of HTLV-3 remains unknown. Lentiviruses, including HIV-1 and -2 the AIDS etiological agents, and Deltaretroviruses, are complex retroviruses. Therefore, in addition to structural and enzymatic proteins they encode regulatory proteins and also auxiliary proteins, the main subject of this work. HTLV-1 and BLV auxiliary proteins play key roles in viral infection in vivo. Whether the genome of PTLV-3 encodes such proteins was not determined yet. Therefore their characterization was the first goal of my PhD work. We identified in vitro messenger RNAs encoding 3 new putative proteins. Their impact on the PTLV-3 viral life cycle in vitro and their expression in vivo were then investigated. As a second part of this work, we examined the relationship existing between the Vpx HIV-2 auxiliary protein and its ability to interact with a restriction factor named SAMHD-1. Vpx induces SAMHD-1 degradation and the kinetic of such degradation allows the virus to replicate in myeloid cells. Altogether, these projects provide new insights into the understanding of the roles played by retroviral auxiliary proteins in connection with a tight regulation of viral life cycle and an escape from innate immunity

Full textThe research in question aimed to demonstrate the advantages not only commercial and technical, but also environmental and occupational use of citric acid in textile dying companies, compare with acetic acid, aiming at implementing a more sustainable dyeing process, as that the requirement of regulatory agencies has grown in recent years and the search on reducing operating costs and environmental adaptations are of vital importance for the survival and perpetuation of textile dyeing companies. Comparative tests were of measurements of pH, neutralization of alkaline baths, theoretical comparison of biodegradability and damage to health and comparative practice tests against dispersants and sequestering dyeing and finally the practical results of dyeing in laboratory scale. The results demonstrated the compatibility of citric acid compare with acetic in the pH adjustment and neutralization of the alkali bath, demonstrated the ability of citric acid in the dispersing disperse dyes upper market dispersants, and higher power as compared to other complexing acids and Ladiquest 1097 and finally based on the environmental data theoretical superiority of citric acid compared to acetic acid, citric acid having a COD value of approximately 30% lower than the toxicity acetic acid and around 70% lower, and finally by the dyes could prove the efficacy of citric acid in polyester and polyamide dyeing processes with no significant change in the processes with acetic acid. The research may show that the substitution of acetic acid, in dyeing processes, the citric acid is feasible and also brings reduction in process costs in the order of 12% in the dyeing of polyester and 0.76%in the polyamide dyeing, will environmental and occupational benefits to companies that adopt this replacement, causing the citric acid in the processing firms is considered a sustainable feedstock.
