Full textThis dissertation seeks to find the matrixes of the concept of anthropophagy created by the modernist Oswald de Andrade, as it was formulated in the Manifesto Antropófago of 1928 and later works, such as the play O Rei da Vela (1933) and the philosophical thesis A Crise da Filosofia Messiânica (1950), from the standpoint of a line of thinking which seeks to analyse the alterative processes of identity formation in peripheral countries. Oswald de Andrade was the author of many of the most audacious avant-guard experiences in Latin America and his writings enlighten Brazil´s history ever since. Following this problematic, this dissertation aims also to understand, through the reading of the works of Oswald de Andrade which was developed by the tropicalist movement in the 1970´s, as well as its contemporary reception, the complex articulation of modernist art and the cultural and political history of the country.

Full textL'elecció de Sa Calatrava com a unitat d'anàlisi respon precisament a la voluntat de la recerca d'estudiar els efectes de la globalització neoliberal en contextos heurísticament apropiats per a la investigació qualitativa de matriu antropològica. Sa Calatrava complia aquest perfil. Per una banda, les seves reduïdes dimensions (menys de 2000 habitants) permeteren un treball de camp etnogràfic detallat amb residència in situ que s'estengué durant dos anys. Per l'altra banda, a mitjans dels anys 90 l'Ajuntament de Palma emprèn un gir clar i explícit de caràcter neoliberal de les seves polítiques urbanístiques pel qual el principal objectiu d'aquestes ja no és la satisfacció dels interessos dels residents, sinó la creació d'oportunitats de plusvàlua que puguin atreure fluxos globals de persones i capitals. Aquest gir es fa especialment manifest en aquells barris del centre històric que, com Sa Calatrava, eren objecte de reforma urbanística. En aquests barris la gentrificació és el procés central que permet la realització de la plusvàlua, tenint no obstant en compte que el bessó d'aquesta plusvàlua no es troba en la venda d'un immoble, sinó en el procés pel qual els immobles d'una zona de la ciutat han tingut una revalorització major a la dels la resta de la ciutat
Per a dur a terme aquesta revalorització, i més enllà de les renovacions de l'entorn construït i de les ajudes directes i indirectes a la inversió, dos factors, profundament relacionats, han estat fonamentals. Per una banda ens trobem amb la posada en joc d'una retòrica sobre el valor cultural i patrimonial del barri oficialment adreçada a atreure turistes, retòrica que suposa una eufemització, i per tant una ocultació i legitimació, de l'augment del valor econòmic. Per altra banda ens trobem amb l'eradicació d'aquells elements que s'associaven amb la degradació i l'estigma del barri. Més enllà de l'expulsió de determinats residents, aquesta eradicació s'ha dut a terme mitjançant la pacificació de l'espai públic i de les activitats que s'hi duien a terme (reunions informals, mercadillos setmanals, etc.). Aquesta erosió de l'espai públic com a espai de comunicació i relació pels residents en favor d'una concepció de l'espai públic com a lloc de gaudi estètic pels visitants és un element central de la tesi. Així, serà en bona mesura aquesta erosió de l'espai públic la responsable que quan els gentrificadors vagin poblant el barri hi hagi un profund desconeixement entre aquests i els antics veïns, una cesura entre els dos grups demogràficament identificables.
Això ens du a la qüestió final i central de la despolitització. Amb aquest terme volem agrupar tres processos que juguen un paper central en el procés de producció de Sa Calatrava com un espai idoni per a l'extracció de plusvàlues: (1) la despolitització d'aquelles instàncies polititzades, com les Associacions de Veïns, que són captades pel poder polític i juguen un paper clau en la legitimació i articulació de l'embelliment i la pacificació del barri. (2) L'erosió de les possibilitats que emergeixi una acció col·lectiva hegemònica, el que s'observa en l'erosió de les dimensions relacionals de l'espai públic, la divisió dins el barri i en la substitució de categories com veí o resident (i dels drets instituïts associats a elles) per d'altres com visitant o propietari. 3) Quan aparegui l'acció col·lectiva serà canalitzada de tal manera que emfasitzi el valor de canvi de l'espai i la possible producció de plusvàlua. Aquest darrer punt s'observa molt carament en el fet que a Sa Calatrava aquells grups que arriben a articular-se contra el desenvolupament dels plans urbanístics acaben apel·lant al valor cultural i patrimonial del barri i a la necessitat que aquest (que no oblidem que és un element legitimador del procés neoliberal de regereneració) sigui preservat. La conclusió final que s'extreu de la tesi és doncs que la despolització no és un efecte o un epifenomen de la voluntat de benefici que guia l'urbanisme neoliberal, sinó un element central d'aquest en dos sentits. En primer lloc aquesta despolitització és un requisit per a què l'extracció de plusvàlua es pugui realitzar de manera eficient (p.e. per a què no hi hagi protestes articulades). En segon lloc és en si mateixa un objectiu de l'urbanisme neoliberal, que d'aquesta manera pot ser considerat no només com una eines econòmica sinó com a un mecanisme de control polític i governamentalitat. Aquesta entenem que és una característica aplicable a tot el procés de neoliberalització, de tal manera que podem considerar-lo com una estratègia classista.
"Sa Calatrava mon amour" is the history of 30 years (from 1975 to the present) of collective action in Sa Calatrava (Majorca, Spain), a neighborhood that during the past fifteen years has been subjected to multiple plans of urban regeneration. Sa Calatrava is a very small neighborhood (around 2000 inhabitants) situated in the eastern part of the seafront of the historical center of Palma, the capital city of Majorca, one of the main tourist destinations in the Mediterranean.
My doctoral research, based on a two-year fieldwork, deals with the relationship and coherence between the forms of collective action in Sa Calatrava and the plans of urban regeneration, with their aim to increase the real estate values of the area. The central hypothesis of the research is that the process of neo-liberalization is not only an economic process that imposes a discipline of value but also requires the depoliticization of society. Beyond the depoliticization of grassroots movements and groups, this process of depoliticization is grounded on the loss of control of its own space by inhabitants and consequently the substitution of categories like neighbor/resident by others such as user, buyer or visitor and the erosion of the public and relational dimensions of public space.
Gentrification is the way by which real estate surpluses are being obtained in the area, but they are produced somewhere else. It is in the production of Sa Calatrava as a valuable setting through the investment in the built environment (façade refurbishing, street renovations, etc.) and through the creation of a culturally valuable narrative based on heritage and history (officially targeted at attracting tourists) where we must find the social production of a space suitable to the needs of the realtors and constructors. For surplus values to be efficiently extracted the neighborhood must be embellished and pacified, an public space loses its role as a space for communication and sociability. Consistently, conflicts among different groups of residents, as well the loss of control of its own space by inhabitants is not a consequence of the gentrification process, but a consequence of the way space has been produced in order to enhance exchange value.

Full textThe present study has been carried out with the objective of examining the effects of the exchange of conditioned reinforcement (tokens) with the final reinforcement (gifts), on children, by manipulating the delay of points and of exchange in choices between a delayed reinforcement of higher value (self-control) and an immediate reinforcement of lower value (impulsiveness). Such choices have been regularly presented in experimental studies of self-control. This study has been performed in seven children with ages between 8 and 10, who have been submitted to a concurrent-chain schedule with 3 periods in a notebook. In the first period, called period of choice, a VI10-VI10 was programmed to each of the two components presented on the computer screen. The choice of one of them produced, as a consequence, the period of delay of the reinforcement (FT), characterized by the screen becoming black. After that, a new period started in which the acquisition of tokens was possible. All the participants have been submitted to four different experimental conditions. The first two consisted in evaluating the control of dimensions such as delay and magnitude of the reinforcement over the action of responding and were called correspondently evaluation of sensitivity to the delay of the reinforcement and evaluation of sensitivity to the magnitude of the reinforcement. The other two conditions were called point-delay and exchangedelay. The point-delay condition consisted of submitting the participants to three values of delay (30 , 75 e 120 ) between the emission of a response in the period of choice (VI10-VI10) and the period of acquisition of the conditioned reinforcement (tokens which presented on the computer screen). At the end of each experimental session he screen showed the number of tokens received e these tokens were exchanged for the final reinforcement (gifts). The condition of exchange-delay, consisted of submitting the participants to three values of delay (1,7 and 14 days) to perform the exchange the conditioned reinforcement for the gifts. The period of delay after the period of choice was always 1 second in this condition and the tokens were made available after this delay. However, the exchange for the final reinforcements was only performed on the days determined by the contingency in operation, not at the end of the session as in the point-delay condition. The results showed that all the participants were sensitive to the dimensions delay and magnitude of the reinforcement in the evaluation of their sensitivity to them. Considering the conditions of delay of scoring and exchange delay, four amoung the seven participants preferred the alternative of self-control and three preferred the alternative of impulsiveness, in both conditions. Hence, the effect of the variable exchange-delay was not observed to be different from the effect of point-delay on the participants response
O presente estudo foi realizado com o objetivo de examinar os efeitos do atraso de troca de reforço condicionado (fichas) pelo reforço final (prêmios), em crianças, manipulando atraso de pontos e atraso de troca em escolhas entre reforço de maior magnitude atrasado (autocontrole) e reforço de menor magnitude imediato (impulsividade), escolhas comumente apresentadas em estudos experimentais de autocontrole. Para tanto, sete crianças com idade de 8 a 10 anos foram submetidas a um esquema concorrente encadeado com três períodos em um notebook. No primeiro período, período de escolha, estava programado esquema concorrente VI10-VI10 para os componentes apresentados na tela do computador. A escolha de um dos componentes produzia como conseqüência o período do atraso do reforço (FT), caracterizado pela cor preta em toda tela do computador. Após o FT, iniciavase o período disponível para obtenção de fichas (reforço condicionado). Todos os participantes foram submetidos a quatro condições experimentais. As duas primeiras consistiram em avaliar o controle das dimensões atraso e magnitude do reforço sobre o responder e foram denominadas de avaliação da sensibilidade ao atraso do reforço e avaliação da sensibilidade à magnitude do reforço. As outras duas condições foram chamadas de atraso de pontos e atraso de troca. A condição de atraso de pontos consistiu em submeter os participantes a três valores de atrasos (30 , 75 e 120 ) entre a emissão das respostas no período de escolha (concorrente VI10-VI10) e o período de obtenção do reforço condicionado (fichas que eram apresentadas na tela do notebook). Ao final da sessão experimental, aparecia na tela a quantidade de fichas recebidas e estas eram trocadas pelo reforço final (prêmios). A condição de atraso de troca consistiu em submeter os participantes a três valores de atraso (1, 7, 14 dias) para a troca do reforço condicionado pelos prêmios. O período de atraso, após o período de escolha foi sempre 1 segundo, nesta condição, e as fichas eram disponibilizadas após este atraso, porém eram trocadas pelos reforços finais nos dias estipulados pela contingência em vigor e não necessariamente ao final da sessão, como na condição de atraso de pontos. Os resultados mostraram que todos os participantes foram sensíveis às dimensões atraso e magnitude do reforço nas avaliações da sensibilidade de tais dimensões. Considerando as condições de atraso de pontos e de atraso de troca, de uma forma geral, quatro, dos sete participantes apresentaram preferência pela alternativa de autocontrole e três apresentaram preferência pela alternativa de impulsividade, em ambas as condições. Assim, não foi observado um efeito da variável de atraso de troca diferente da variável de atraso de pontos sobre o responder dos participantes. Ressalta-se também que as seqüências de atrasos que tinham seus valores gradativamente aumentados (fading) produziram preferência pela alternativa de autocontrole em praticamente todas as ocorrências

Full textThe majority of managers tend to think that their problems are solved after having found an emloyee who is able and agrees to fill a job vacancy. However, from the very first day it is vital to persuade an employee of his or her right choice and necessity for this company in order to make an employee to be in the mood for a qualified, productive work and the application of his or her knowledge, as well as abilities in his or her new work. An employee should feel safe and belonging to a new workplace. The appropriate involvement of a new employee into the organisational activity can make a new employee and other employees in that organisation certain that it will not bring any problem.

Full textIn a variety of cases multivariable systems can be treated as single-input, single-output (SISO) systems for control purposes. The works found in the literature for time-delay systems are generally for SISO systems. In this work the application of multivariable control techniques to dynamic systems with multiple time-delays in the input is explored. We consider the application of the Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) technique to two study plants. The first is an electrical oven used in metal casting processes with 6 inputs and 6 outputs and the second a column of binary distillation system with 2 inputs and 2 outputs. The two plant models present multiple time-delays in the input. We present the LQG/LTR control simulation results along with comparisons.

Esta tese apresenta contribuições para a melhoria da solução do controle de processos com atraso, através de estratégias de controle preditivo baseado no modelo (MPC) que incorporam aspectos como robustez, restrições e otimização multiobjetivo. As contribuições estão relacionadas à duas áreas: (i) controle de processos com atrasos dominantes e (ii) otimização multiobjetivo do controle. Para análise do efeito do atraso no comportamento do sistema em malha fechada, desenvolve-se uma nova formulação do controlador preditivo por matriz dinâmica (DMC), mostrando que este é composto por um controlador primário mais um preditor. Esta formulação permite avaliar analiticamente o efeito do atraso no DMC, comparado a outros controladores MPC, através de índices de robustez. Esta análise possibilita selecionar o algoritmo MPC mais adequado à implementação prática em processos com atraso, especialmente quanto à robustez do controle frente a variações paramétricas na planta. Do ponto de vista da otimização do controle, busca-se desenvolver estratégias de controle preditivo que consideram aspectos econômicos no projeto de controle, além das restrições técnicas e/ou operacionais que habitualmente constam nos requisitos de aplicações reais. As estratégias de controle propostas utilizam um nível supervisório para determinar as referências ótimas de controle para um nível regulatório. O nível supervisório baseia-se em um otimizador de múltiplos objetivos, projetado a partir de regras que integram heurística, lógica e dinâmica do processo por meio de expressões descritas através de lógica proposicional, ou por estruturação formulada através de regras de decisão. As soluções ótimas obtidas via otimização multiobjetivo funcionam como referências desejadas para o cálculo da lei de controle do algoritmo MPC. Diversas aplicações em plantas piloto e industriais ilustram os resultados obtidos com as diferentes estratégias desenvolvidas.

Este trabalho apresenta diferentes estruturas de um compensador de atraso de transporte, denominado preditor de Smith filtrado, com base no controlador preditivo generalizado, em conjunto de técnicas para evitar o windup do controlador, causado, na maioria das vezes, pela saturação do atuador. Essa proposta tem como objetivo tratar restrições de amplitude de sinal de controle e obter um desempenho subótimo, sem a necessidade de um processo de otimização para tratar a não linearidade imposta pela restrição, como tipicamente ocorre no controlador preditivo generalizado. Foram realizadas simulações de processos abordados na literatura e o desempenho da técnica proposta foi comparado ao desempenho do controlador preditivo generalizado. Também foi realizado um estudo de caso experimental em uma bancada de ensaios que permitiu comparar os resultados da sintonia proposta e do controlador preditivo generalizado para o controle de temperatura da água de uma ducha eletrônica. Tanto os resultados de simulação quanto os experimentais demonstram que no caso de restrições de saturação da amplitude de controle a técnica proposta é capaz de alcançar desempenho de controle muito próximo do ótimo com um esforço computacional muitas ordens de grandeza menor que o demandado pelo controle preditivo generalizado.
Abstract : This work presents different structures of a dead time compensator, known as filtered Smith predictor, based on the generalized predictive controller, with a set of techniques to avoid the windup of the controller, caused, in most cases, by saturation of the actuator. This proposal aims to handle control signal amplitude constraints and achieve suboptimal performance without the need of an optimization process to handle the nonlinearity imposed by the constraint, as typically occurs in the generalized predictive controller. Simulations of processes presented in the literature were performed and the performance of the proposed technique was compared to the performance of generalized predictive controller. An experimental case study was also carried out on a test rig, which was used to compare the results of the proposed tuning and the generalized predictive controller for the control of the water temperature in an electronic shower. Both the simulation results and the experimental results demonstrate that in the case of control amplitude saturation constraints the proposed technique is able to achieve control performance close to the optimum, with a computational effort many orders of magnitude smaller than that required by generalized predictive control.

Full textThe aim of this work was to isolate and identify microorganisms, to estimate their ability to assimilate the substances with a lot of chains with any number of carbon (C) atoms. There were collected the samples, from the surfaces of cheese polyethylene packing in the storeroom – fridge. In accordance with their morphology there were isolated 12 bacterial strains. There was estimated the bacterial strains dependence on the temperature. I can propose, that the bacterial strains belongs to the facultative psychrophyles (psychrotrophs). There were analyzed the physiological properties of the bacterial strain: the composition of the cell wall, sugar fermentation, gelatin hydrolysis, starch hydrolysis, casein hydrolysis, tryptophan degradation, oxidase and catalase tests. According to the results of these test, there was made the clusters analysis and was determined the similarity of the bacterial strains. There was estimated the ability to assimilate hydrocarbons as the fragments of polyethylene, because the bacterial strains were isolated from the polyethylene surfaces. According to the results, there was determined that the bacterial strains assimilated the tetradecane, hexadecane and docosane. It means that after a long time these bacterial strains would start to assimilate the polyethylene as a sole carbon source. There was chose up the S7 bacterial strain for the identification. According to the results of the 16 S RNA gene analysis, there was determined that the analysed... [to full text]

Full textNot long ago people with intellectual impairment were an isolated and stigmatised part of society in Lithuania. The situation has changed. Depending on the degree of intellectual impairment, mental disability determines minor to serious impairment in all areas of development of general abilities (cognitive, emotional, physical and social), thus limiting human capabilities. Children suffering from moderate intellectual impairment experience linguistic, motor, cognitive and communication difficulties. Dancing games encompass poetry, music, drama and choreography. In the context of the education of disabled people, instead of being based on the quality of movements, these games should become a means of education and communication ensuring full practical functioning of students. The subject matter of the thesis is selection of dancing games for children with moderate intellectual impairment. The purpose of the thesis is to reveal the specific features of dancing games adapted for children with moderate intellectual impairment. Objectives: to analyse the specific features of this type of impairment and provide the psychological and educational characteristics of children with moderate intellectual impairment; to highlight the applicability of dancing games in the dance training process; to identify the specificity of the use of dancing games in the dancing activities of children with moderate intellectual impairment; to justify the criteria for the selection of dancing games for...

Full textLipases are widely researched enzyme group because of their ability to catalyze a wide range of synthesis reactions. The aim of this doctoral thesis was to study and optimize fatty acid ester synthesis using lipases. The influence of enzyme choice, its preparation (immobilization), choice of substrates and reaction conditions on fat hydrolysis, biodiesel and phenethyloctanoate (flavour ester) synthesis reaction course and yield was studied. Enterobacter aerogenes lipase, which was developed in Lithuania, was immobilized and its properties were determined for the first time. Commercial lipases were used for hydrolysis and synthesis reactions, the influence of reaction parameters was determined using response surface methodology, and so the yield was optimized. Silica gel was found to be a promising reaction additive for acyl group migration catalysis in biodiesel synthesis reaction.

In the Probabilistic Delay Constrained Shortest Path problem we aim to consider the time factor in the design of cargo routing paths in road networks at minimum cost, considering the increasing uncertainty in travel times of these routes in real networks, and keeping in mind strategies of quality of service, in order to obtain a compromise between the travel costs and the compliance of the arrival time at the destination. We conducted a study of related problems in the literature of transport networks optimization, in order to better understand the problem to be addressed, about which we are not aware of existing works. We developed a scheme for enumerating partitions of the solution space of this problem, which uses an L decomposition to select these partitions wisely, and is aided by solutions to relaxations of the problem to obtain bounds for the optimal cost. In addition, we developed some branching and pruning strategies for a Branch-and-Bound scheme, with a pre-processing phase, in order to try and solve the problem directly. The computational results show that we are competitive with the commercial tool used for comparison in the smaller instances. For the remaining instances, this tool is more efficient in the time required for solving the problem.

Full textThe objective of this thesis is to verify the influence of family characteristics in schooling delay. The schooling delay in Brazil increases government?s spent and implies lower rate human capital accumulation on children. Lower rates of human capital accumulation means children will grow into less skilled workers, with low levels of productivity, which has a negative effect on development. The accumulation of human capital is a process that depends of the individual?s development throughout her life. The study considers family factors that have an evident influence in children development, reinforcing that the family is one of the main sources in the process of accumulative human capital. The variable used as proxy to human capital accumulation was schooling delay, which is a count variable and is clearly to endogeneity. The approach in this thesis is referred to as the two-stage quasi likelihood. Results obtained indicate that Parent?s education have a negative effect in the child?s being behind at school, while household income has a positive effect. Additionally, the difference in magnitude when compared with standard estimation methods is significant.

Full textChoices between immediate and delayed consequences have been studied trough mathematical models that describe the delay discounting phenomena. Several studies have investigated this phenomenon with delayed and immediate appetitive stimuli. Few have studied the situation involving delayed and immediate aversive stimuli, although it has been suggested that the models that describe the appetitive scenario would well also describe the aversive scenario. The aim of this research was to compare choices made when the appetitive and aversive scenarios are presented. Participants were 36 volunteers, undergraduate students, aged 18 to 28, both sexes. Informed consent was given. Data collection was made in a PC computer and consisted of a series of hypothetical choices between immediate and delayed monetary values. A titration procedure was used in which participants choose between a fixed delayed value of R$1,000.00 (1 week, 1 month, 6 months, 1 year, 3 years, 5 years, 10 years and 25 years) and a variable immediate value that could range from R$1.00 to R$1,000.00 in either a gain situation (appetitive-APT) or a payment situation (aversive-AVS). The order of the situations was counterbalanced. For each delay and in each situation an indifference point representing the immediate value of the delayed value was calculated. The difference between the points for the AVS and APT situations was calculated. A linear regression analysis revealed that the slope (C1=0.05) is significantly different of zero (p<0.08), indicating that the indifference points are smaller for APT than for AVS. The analysis of the area under the curve formed by the indifference points corroborated this conclusion and indicated the absence of correlation between the areas in the APT and AVS situations (r = 0.306; ns). Individual data revealed three response patterns: a pattern of negatively accelerated discounting, a pattern of stability characterized by the absence of discounting and a pattern characterized by an initial discounting followed by an increase in the indifference points for larger values of delay. The analysis of the mathematical models revealed that two hyperbolical with exponent models described also the data in APT (called Hyperbolic-Exponential and Greens). For the AVS situation the models found in the literature failed to describe the data obtained. An alternative model has been proposed in which the aversive value of the delay is modulated by two parameters (U and S) and added to the Hyperbolic-Exponential model. Such model was effective in describing the data obtained in the AVS situation and could be generalized to the APT situation, with better results than the other two mentioned above. The analysis of the estimated parameters revealed the absence of correlation between the two situations and only the U parameter for the AVS situation is significantly different from the same parameter obtained in the APT situation (p<0.06). Taken together the analysis indicates differences between choices involving delayed appetitive and aversive stimuli.

Full textThe myricanol, a natural [7.0]-meta-cyclophane which belongs to the family of strained and cyclic diarylheptanoids, possess an interesting structure and attractive biologically activities (anti Alzheimer and anti cancer properties). Actually only two synthesis of racemic (+/-)-myricanol have been reported in the literature. The goal of this research was to prepare this strained cyclophane in a racemic and then in an atropostereoselective route taking into account the challenging ring closure. Thus a linear diarylheptanoid was prepared using an efficient cross-metathesis reaction followed by an intramolecular Suzuki-Miyaura domino reaction giving rise to the desired cyclophane with 2.55% overall yield in 11 steps. On the other side, the biaryl core of myricanol was envisaged by an intermolecular metallo-catalysed coupling reaction between already highly functionalized fragments, followed by a ring closure metathesis. Two advanced intermediates were already attempted

Alguns autores referem a influência do estado emocional da grávida na vida fetal, considerando algumas patologias fetais e neonatais como capazes de serem condicionadas em parte pela vivência da gravidez pela mãe e pelo pai. Foi feito um estudo de caso de atraso de crescimento intra-uterino, tendo como objectivo explorar as representações e a depressividade maternas. Neste caso, não se constatou depressividade materna, todavia verificou-se um impasse afectivo e relacional, por parte quer da mãe quer do pai, que poderá ter tido um impacto na vida emocional fetal e condicionado o seu equilíbrio psicossomático. Estes progenitores terão investido deficitariamente no seu bebé-feto. A patologia psicossomática do feto terá sido o espelho das dificuldades de gestão dos afectos pelos pais, tendo-os colocado em risco de um adoecer somático. A presente investigação permitiu reflectir sobre a influência exercida pelo relacional, ligado aos processos de identificação/construção da identidade, à família uni ou biparental e ao adoecer psicossomático, numa patologia fetal pouco frequente mas considerada de risco. A análise deste caso poderá conduzir a um estudo científico, baseado em técnicas quantitativas, sobre a personalidade dos pais de bebés com atraso de crescimento intra-uterino assimétrico e a avaliação psicológica destes bebés.

Full textChildren with language delay are usually identified by the age of two years old, and are appointed by their smaller vocabulary than peers of the same age, although without any underlying pathology. Tasks of responding by exclusion and contextual cue have been reported in the literature as resources to study the possible difficulties present in the verbal repertoire of children with language delay. Two studies were developed to explore the performance of this population in these tasks: the first tested the responding by exclusion of children in matching-to-sample tasks for the teaching of audio-visual conditional discriminations with names and pictures of objects. The second also used matching-tosample tasks and assessed the responding by exclusion at probes with auditory stimuli with topography of nouns and verbs in gerund, using as stimuli comparison videos of actions and images of static objects. The participants were 64 children, 32 with typical development and 32 with language delay, ages 3 and 4 years-old. These studies had as general objectives: a) to investigate the occurrence of responding by exclusion in objectname relations in children with language delay indications compared with children with typical development, and b) to verify the interference of contextual cues in responding by exclusion, using stimuli with topography of nouns and verbs. The results in both studies indicate that children with normal development and language delay can display responding by exclusion consistently since a baseline procedure ensures learning the task. The results of the second study, however, indicate that both groups exhibited a sudden decrease in their performances in tasks of responding under the control of lexical cue. Differences were found during the acquisition of baseline verbs, in which the typically developed children presented a significantly better performance than children with language delay. Significant differences were also found comparing ages: between children of 3 and 4 years old from the same group, and amid 3 year-old-children from different groups, but the same was not found in relation to the participants of 4 years from different groups. These findings indicate that language delay did not affect the responding by exclusion, even with different lexical classes stimuli. In addition, baseline training with nouns and verbs was not sufficient to establish two classes of effective stimuli and to maintain a responding performance as robust as the exclusion probes phase for all children.

The object of this dissertation was focused on the analysis of elements of the perception of Brazilian backwardness as an ideology in close relation with the modernization process in our country. Aspects of this perception, taken in its impressionistic manifestations, often do not relate only to the objective conditions of reality, but also to an even pre-reflective willingness, that reveals, in turn, a sense of inferiority. Thus, here it was tried to deepen the analysis of this ideological component to the extent that it is somewhat reproduced in the social and political thought produced by interpreters of Brazil. Some reflections of the sociologist Jessé de Souza on the Gilberto Freyre s works Casa-grande e senzala and Sobrados e mucambos were taken as an axis, giving prominence to the notion of "Brazilian cultural uniqueness", among others. In these arguments, it was attempted to establish points of contact and divergence with Raízes do Brasil by Sérgio Buarque de Holanda
O objetivo desta dissertação esteve voltado para a análise de elementos que informam a percepção do atraso brasileiro, enquanto ideologia em estreita relação com o processo de modernização em nosso país. Aspectos dessa percepção, tomados em suas manifestações impressionistas, frequentemente não se relacionam apenas às condições objetivas da realidade, mas também a uma disposição até mesmo pré-reflexiva, que revela, por sua vez, um sentimento de inferioridade. Assim, tenta-se aqui aprofundar a análise dessa componente ideológica, na medida em que esta se reproduz - de certa forma - no pensamento social e político produzido por intérpretes do Brasil. Tomaram-se como eixo algumas reflexões do sociólogo Jessé de Souza sobre as obras de Gilberto Freyre, Casa-grande e senzala e Sobrados e mucambos, conferindo-se destaque à noção de singularidade cultural brasileira , entre outras. Nestas argumentações tentou-se estabelecer pontos de contato e divergências com Raízes do Brasil, de Sérgio Buarque de Holanda

Os controladores PID (proporcional, integral e derivativo) avançados são controladores compostos de estrutura PID, cujos parâmetros são sintonizados por um dos métodos pertencentes ao controle inteligente, robusto, preditivo, adaptativo, não-linear ou ótimo, sem que se modifique o princípio de atuação desses parâmetros. A proposta desta dissertação é desenvolver e comparar diferentes técnicas de controle PID avançadas aplicadas ao controle, em ambiente de simulação, da espessura de chapas de aço produzidas por um laminador quádruo simples. A motivação deve-se ao fato de ser a laminação a área de maior influência no custo operacional do aço, além do constante esforço dos engenheiros para melhorar o desempenho, a produtividade e a qualidade do produto. No estudo de caso obtém-se a modelagem de uma cadeira de laminação, observando-se as variáveis pertinentes ao controle, bem como a descrição dos principais problemas como o atraso de transporte inerente à medição de espessura e o efeito da excentricidade devida a imperfeição dos cilindros. A dissertação aborda estratégias de controle PID avançados visando melhor o tratamento do atraso de transporte, usando abordagens de controle preditivo generalizado e compensadores PID, apresentando as etapas de desenvolvimento das abordagens avançadas a partir da técnica clássica. As simulações são realizadas para análises do comportamento regulatório da malha de controle, da robustez e da tolerância à excentricidade em regime permanente.

Este trabalho apresenta um estudo direcionado à análise e projeto de controladores preditivos baseados em modelo para sistemas lineares e não lineares com atraso, visando a melhoria da robustez e levando em conta aspectos práticos de aplicação. O estudo considera sistemas lineares estáveis, integradores, instáveis, não lineares e um estudo de caso na área da medicina. No primeiro caso, estudam-se as condições que deve satisfazer um sistema de controle preditivo linear para garantir a estabilidade robusta de malha fechada quando se controlam processos estáveis com incertezas no atraso. No segundo e terceiro apresenta-se o estudo do controle preditivo de sistemas lineares com dinâmica integradora ou instável e atraso e propõe-se um novo algoritmo que utiliza idéias de controladores de compensação de tempo morto robustos. No caso de sistemas não lineares propõe-se a extensão das propriedades de robustez de um algoritmo utilizado em sistemas de controle lineares com atraso para processos não lineares com atraso. Finalmente apresenta-se um estudo de caso aplicado à dosagem de anestesia a pacientes durante cirurgia, com garantia de estabilidade sob condições de operação. Resultados de simulação ou ensaios numa planta piloto são apresentados para cada tipo de controlador proposto, mostrando as vantagens dos métodos de ajuste, que principalmente estão orientados a melhorar a robustez e permitir a sua aplicação simples em processos industriais. This work presents the analysis and design of model-based predictive controllers MPC for linear and nonlinear dead-time systems. The proposed control strategies take into account both practical aspects and robustness specifications. The study considers: (i) stable, integrative and unstable linear systems, (ii) nonlinear systems and (iii) a medicine area case study. In the first case, the necessary conditions to guarantee the robust stability when MPC are applied to stable processes with dead time are studied. In addition, it is proposed a robust predictive controller for integrative or unstable linear processes with dead time. This controller uses some of the robustness ideas of dead-time compensators. In the second case, the robustness properties of linear predictive controllers are extended for stable nonlinear processes with dead time. Finally, it is presented a case study where the robust MPC is applied to drug dosing during anesthesia in patients undergoing surgery. Also, a tuning rule is obtained to guarantee the stability of the system under operation conditions. Experimental or simulation results are presented for each proposed controller, to illustrate the advantages of the tuning methods.

Com o aumento da demanda do mercado da construção civil, algumas empresas têm encontrado dificuldades para cumprir prazos, em virtude de diversos fatores, o que pode gerar atraso na entrega dos imóveis. O objetivo desta pesquisa é verificar os fatores associados para a ocorrência do atraso, bem como,a percepção dos proprietários dos imóveis. Para verificar os fatores associados ao atraso com maior importância, foi aplicado um questionário com 57 itens, em 31 empresas, nos municípios de Balneário Camboriú e Itajaí no estado de Santa Catarina. Para obter a frequência do atraso na entrega foram verificados o total de empreendimentos e os imóveis entregues com atraso no período entre dezembro de 2009 e janeiro de 2011, sendo que desta população foi retirada uma amostra de 82 proprietários para verificar as consequências do atraso. Por fim, foram consultados três corretores da região para avaliar o prejuízo para os proprietários caso o imóvel estivesse alugado durante o período do atraso. Os resultados demonstraram que a frequência dos edifícios entregues com atraso foi de 53,8%; os cinco fatores com maior índice de importância para a ocorrência do atraso foram: escassez de mão de obra; mudanças solicitadas pelo cliente final; mão de obra não qualificada; atrasos nos trabalhos dos subempreiteiros e retrabalho em virtude de erros. Nenhum proprietário entrevistado acionou judicialmente a empresa, sendo que a consequência do atraso mais citada foi de ordem financeira. Foi observado que os valores de indenizações referentes ao aluguel dos imóveis entregues com atraso variam de R$ 2.757,57a R$ 66.652,04, sendo que a indenização total a ser paga pelas construtoras seria de R$ 8.029.008,00. Conclui-se que o atraso não é um fato isolado da região, entretanto, as empresas e os clientes ainda têm dúvidas quanto aos seus deveres e direitos, decorrentes do não cumprimento do prazo.
With the increasing demand of the construction market in Brazil, some companies have found it difficult to meet deadlines due to several factors which can lead to delay in buildings. The objective of this research is to look at the prevalence and associated factors for the occurrence of the delay, as well as the consequences for the owners of the buildings. To verify the factors associated with the delay which have the highest importance, a questionnaire with 57 items in 31 construction companies in the municipalities of Balneário Camboriú and Itajaí in the State of Santa Catarina was applied. To obtain the prevalence of delay, was checked the total of buildings and apartments delivered with some late in the period between December 2009 and January 2011. In this population, a sample of 82 owners to verify the consequences of delay was picked up. Finally, three estate agents were consulted in the region to assess the damage to the owners if the properties were rented during the period of delay. The results showed that the prevalence of buildings delivered late was 53.8%; the five factors with highest importance to the occurrence of the delay were: workers shortage; changes requested by the final customer; unqualified workers; delays in the work of sub-contractors and rework in due to errors. No owner interviewed fired judicially the company and the more cited consequence of delay was financial. It was observed that the claims relating to the rental values of properties delivered late vary from R$ 2.757,57 to R$ 66.652,04 and the total compensation to be paid by construction companies would be R$ 8.029.008,00. It is concluded that the delay is not an isolated fact of the region, however, companies and customers still have doubts as to their duties and rights arising from failure to comply with the time limit.

Nesse trabalho é proposta uma estratégia de Controle Preditivo capaz de controlar de forma robusta processos modelados de forma não linear com atraso de transporte. Essa abordagem é interessante quando considera-se a crescente importância dos controladores preditivos em controle de processos complexos, devido principalmente a sua grande inserção na indústria de petróleo e gás. O trabalho apresenta uma revisão do controle preditivo não linear e do controle preditivo robusto de processos com atraso de transporte. Como resultado dessa análise opta-se por focar os estudos no controlador PNMPC (\textit{Practical Nonlinear Predictive Control}) e nas estratégias de compensação de atraso baseadas no preditor de Smith filtrado, dado que essas oferecem as melhores propriedades para a proposta do trabalho. São realizados estudos da robustez do PNMPC observando o comportamento da incerteza equivalente quando esse controlador está configurado para controlar processos com atraso de transporte. É demonstrado que a incerteza equivalente traz consigo um acúmulo de variáveis da correção fornecida pelo modelo de perturbação, sendo esse um fenômeno indesejado, pois aumenta a norma da incerteza equivalente levando a uma menor robustez do controle em malha fechada. Esse estudo traz um caminho alternativo para aumentar a robustez do PNMPC, pois evidencia o acúmulo das variáveis de correção e traz a possibilidade da utilização de compensadores de atraso explícitos, elucidando um esquema de controle com o PNMPC atuando como um controlador primário que utiliza uma predição fornecida por um preditor para o cálculo do controle; levando assim a uma nova configuração, o PNMPC com um modelo de perturbação modificado. Propõe-se uma estratégia mais robusta para o controle preditivo não linear de processos com atraso de transporte, o PNMPC com compensação explícita do atraso via PSF (preditor de Smith filtrado). E é comprovado analiticamente tanto para o caso linear quanto para o caso não linear o aumento da robustez no controle de processos com atraso de transporte das estratégias desenvolvidas nesse trabalho, o PNMPC, o PNMPC modificado e o PNMPC com compensação de atraso via preditor de Smith filtrado. Para a demonstração analítica da robustez utiliza-se a abordagem da observação do comportamento da incerteza equivalente, possível quando referencia-se o esquema de controle mais o preditor de forma equivalente e analisa-se a relação entre as incertezas. Ainda, durante todo o trabalho são apresentadas simulações de controle que evidenciam o ganho de robustez das estratégias desenvolvidas, simulações essas que comparam as respostas dinâmicas do controle em malha fechada das três estratégias, PNMPC, PNMPC Modificado e PNMPC com compensação de atraso via preditor de Smith filtrado tanto para o caso linear quanto para o caso não linear considerando incertezas na estimação dos atrasos.
Abstract : It is proposed a predictive control strategy able do robustly control nonlinear processes with transport delay. This approach is interesting when it is considered the growing importance of predictive controllers for controlling complex processes, mainly due to its large insertion in the oil and gas industry. This work presents an overview of the nonlinear predictive control and robust predictive control of processes with transport delay. As a result of this analysis it is chosen to focus the studies on the controller PNMPC (Pratical Nonlinear Predictive Control) and on the transport delay compensantion strategies based on filtered Smith predictor as they offer the best properties for the proposed work. It is performed studies of the robustness of PNMPC observing the behavior of the equivalente uncertainty when the controller is configured to control processes with transport delay. It is shown that the equivalent uncertainty brings with itself an accumulation of the correction variable provided by the disturbance model, it is an unwanted phenomenon because it increases the norm of the equivalent uncertainty decreasing the robustness of closed loop control. This study provides an alternative way to increase the robustness of the PNMPC for demonstrating the accumulation of the correction variable and it brings the possibility of using explicit delay compensators. It can clarify a control scheme with PNMPC acting as a primary controller that uses a prediction provided by a predictor for the calculation of control. It is proposed a robust nonlinear predictive control of processes with transport delay, the PNMPC with explicit delay compensation via FSP (filtered Smith predictor. And it is analytically demonstrated for both linear and nonlinear cases the increase of the robustness in control process with transport delay. For the analytical demonstration of the robustness it is observed the behavior of the equivalent uncertainty, that is possible when it is referenced the control scheme more the predictor, in a equivalent way, for analyse the relationship between uncertainties. Also, control simulations show the robustness gain of the developed strategies, these simulations compare the dynamic responses, of the closed loop control, of the three strategies: PNMPC, modified PNMPC and the PNMPC with delay compensator via FSP, for both linear and nonlinear cases and considering uncertainties in the transport delay.

Full textThe experimental data suggests that, as shown in previous works from our laboratory, angiotensin II (Ang II) raises the pHi recovery rate in OKP cells. This upregulation is not enhanced by recombinant AT1aR overexpression, contrary to our initial hypothesis. We believe that, due to signal amplification mediated by G-protein coupled receptors, any increase in AT1aR would be redundant considering the biological phenomenon of interest. On the other hand, results from the ATRAP overexpression group supports our initial hypothesis, pointing an attenuated effect of Ang II over pHi recovery in relation to the remaining groups treated with Ang II. Considering that pHi recovery in OKP cells primarily reflects the Na+/H+ exchange activity mediated by NHE3 antiporter, we can conclude that NHE3 upregulation mediated by AT1aR/AngII is impaired by an increase in ATRAP protein expression.

Full textAtropine is an alkaloid known for acetylcholine inhibition and as antimuscarinic substance and is present in leaves of some species of the family Solanácea, and especially of Atropa belladonna L. The importance of the production of herbal medicines in the pharmaceutical industry has driven scientific studies to develop analytical methods for quantification of chemical markers, present in herbal drugs, and that meet the quality control parameters of the current legislation. Thus, in this work, different methodologies for quantification of atropine (chemical marker predominant in the leaves of A. belladonna) were developed and validated. The methods proposed by High Performance Thin-layer Chromatography (HPTLC), High Performance Liquid Chromatography (HPLC) and Ultra Performance Liquid Chromatography (UPLC) were validated proving to have specificity/selectivity, linearity, precision, accuracy and robustness, and conforming to legislation. In addition, different extraction methodologies were proposed. For the first method of analysis (CCDAE), extraction with dilute acid (H2SO4 0.5 mol/L) followed by liquid-liquid extraction was used, resulting in an average content of 0.2913% atropine. For the second (HPLC), extraction with apolar solvent (methanol p.a.) was proposed, followed also by liquid-liquid extraction and with an average content of 0.2660% of the active. In the third (CLUE), optimization of extraction was done through Fractional Factorial Design, followed by Box-Behnken Design resulting in extraction by the apolar solvent mixture and Water (47% methanol), followed by solid phase extraction (silica) and an average atropine content of 0.3343%. An optimized extract was analyzed in three methods, resulting in atropine levels equal to 0.2905, 0.3598 and 0.3334 % for HPTLC, HPLC and UPLC, respectively. The review of the monograph of the plant material, with identification and physicochemical tests, together with the methodology of determination by HPLC was proposed with the objective of updating the methodologies that today compose the roadmap of quality control of specie in Brazilian Pharmacopoeia, which is in its 5th edition.

Resumo: Este trabalho descreve o estudo das grades de Bragg com chirp, em fibra, a partir de sua análise, caracterização e aplicação à compensação da dispersão em regime linear, com ênfase no aspecto oscilatório do atraso de grupo de grades não-apodizadas. Seu principal objetivo é o de investigar soluções ao problema deste caráter ondulatório através de simulações numéricas e implementações experimentais. Observou-se boa concordância entre ambas. Resultados de simulações sistêmicas são apresentados e discutidos. A penalidade devida às oscilações do atraso de grupo é avaliada e métodos práticos para seu controle são propostos. A redução destas oscilações, a partir dos métodos sugeridos, encontra aplicação em sistemas ópticos, operando em enlaces longos (acima de 100 km) de fibra convencional, com transmissão em taxas iguais ou superiores a 10 Gb/s
Abstract: This work describes a study of chirped fibre Bragg gratings, based on their analysis, characterization and application on dispersion compensation, for optical communication systems operating in a linear regime. It concentrates on the group delay oscillatory behaviour, observed in dispersion compensating gratings, known as Group Delay Ripple. The main scope of this work is to investigate possible solutions to that problem, rather than apodisation techniques, using numerical simulations and experimental implementations. A good agreement between both results was observed. Numerical system simulations are presented and discussed. The penalties due to the group delay oscillation is evaluated and new methods for controlling this ripple are suggested. Those techniques can be applied to long haul sytems (distances greater than 100 km and bit rates equal or greater than 10 Gb/s) operating with standard singlemodefibre

Atualmente, a eficiência dos algoritmos de simulação estocástica para a simulação de redes de regulação gênica (RRG) tem motivado diversos trabalhos científicos. O interesse por tais algoritmos deve-se ao fato de as novas tecnologias em biologia celular — às vezes chamadas de tecnologias de alto rendimento (high throughput technology cell biology) — te-rem mostrado que a expressão gênica é um processo estocástico. Em RRG com atrasos, os algoritmos para simulação estocástica existentes possuem problemas — como crescimento linear da complexidade assintótica, descarte excessivo de números aleatórios durante a si-mulação e grande complexidade de codificação em linguagens de programação — que podem resultar em um baixo desempenho em relação ao tempo de processamento de simulação de uma RRG. Este trabalho apresenta um algoritmo para simulação estocástica que foi chamado de método da próxima reação simplificado (SNRM). Esse algoritmo mostrou-se mais eficiente que as outras abordagens existentes para simulações estocásticas realizadas com as RRGs com atrasos. Além do SNRM, um novo grafo de dependências para reações com atrasos também é apresentado. A utilização desse novo grafo, que foi nomeado de delayed dependency graph (DDG), aumentou consideravelmente a eficiência de todas as versões dos algoritmos de simulação estocástica com atrasos apresentados nesse trabalho. Finalmente, uma estrutura de dados que recebeu o nome de lista ordenada por hashing é utilizada para tratar a lista de produtos em espera em simulações de RRGs com atrasos. Essa estrutura de dados também se mostrou mais eficiente que uma heap em todas as simulações testadas. Com todas as melhorias mencionadas, este trabalho apresenta um conjunto de estratégias que contribui de forma efetiva para o desempenho dos algoritmos de simulação estocástica com atrasos de redes de regulação gênica.
Recently, the time efficiency of stochastic simulation algorithms for gene regulatory networks (GRN) has motivated several scientific works. Interest in such algorithms is because the new technologies in cell biology — called high-throughput technologies cell biology — have shown that gene expression is a stochastic process. In GRN with delays, the existing algorithms for stochastic simulation have some drawbacks — such as linear growth of complexity, excessive discard of random numbers, and the coding in a programming language can be hard — that result in poor performance during the simulation of very large GRN. This work presents an algorithm for stochastic simulation of GRN. We called it simplified next reaction method (SNRM). This algorithm was more efficient than other existing algorithms for stochastically simulation of GRN with delays. Besides SNRM, a new dependency graph for delayed reactions is also presented. The use of this new graph, which we named it delayed dependency graph (DDG), greatly increased the efficiency of all versions of the algorithms for stochastic simulation with delays presented in this work. Finally, a data structure that we named hashing sorted list is used to handle the waiting list of products in simulations of GRN with delays. This data structure was also more efficient than a heap in all tested simulations. With all the improvements mentioned, this work presents a set of strategies that contribute effectively to increasing performance of stochastic simulation algorithms with delays for gene regulatory networks.

Full textThis dissertation aims to examine possible explanations for the backwardness in the expansion of Brazilian primary education between 1930 and 1964, despite the fact that Brazil achieved high rates of economic growth through promoting import-substitution industrialization. In particular, the roles of distribution of political power and decentralization in the expansion of primary enrollment rates are addressed. The data show that during the Estado Novo, a dictatorial regime under Vargas rule, there was decrease in primary enrollment rates. The return to democracy in 1945/46 was beneficial to primary schooling. However, contrary to what happened in developed countries, our evidence indicates that Brazils experience is more similar to what happened in India. Education in both countries developed in the context of a highly elitist democracy, in which the expansion of suffrage had little effect on the expansion of education, with a negative impact on long-term economic growth. In addition to the lack of political voice, the lack of adequate financial resources for states and municipalities was also an obstacle to the development of basic education. Qualitative evidence shows that federal governments were more concerned with tertiary schooling, in detriment to primary schooling. Quantitative evidence, in turn, shows that the level of electoral competition and administrative decentralization had positive effects on enrollment rates in some states, but suffrage expansion seems to have had little influence on primary schooling expansion. The lack of attention given to this schooling level, due to the lack of political voice of the population, probably had negative effects on the structure of income distribution in Brazil throughout the 20th century.

Full textThis work aims to observe the path of the deployment of modernist urban planning in Brasilia and its results. In another words, view the result of implementing a model of modern urban planning, more suitable for industrialized countries, in a society that, according to Francisco de Oliveira, combines the modern with late. For this, the choice was to do first is a reading of Brasilia as object of a national policy aimed at the expansion of domestic consumer markets and the integration of the nation (construction of a nationality), by means of what was called the national development of the Plano de Metas. In that context, it looks to the urban design of Brasilia in order to build an understanding of the precepts which marked the urban design of the new capital and those who ultimately influence the whole process of formation of the urban agglomeration. From these two approaches, analyses the action of the State in the implementation of the federal capital since 1955 to 2005 with regard to three views: the land, the housing and urban planning. After this work, after observation of the formation and evolution of urban city of Brasilia which was established within a national policy for development, it is an analysis of modern urban planning of Brasilia from the perspective of the interpretation of theoreticians about the Brazils society and the Brazilian state.

Full textThe Internet may does not meet all the demands required by applications sensitive to delay. Voice, video or even game applications demand low delay. The distance of hops between client and server, link traffic and the ramdomness of the package path, may cause delays. There is motivation and even implementation of alternative infra-structure to improve access. One example is the COMEP Network project, that proposes an alternative network in order to comply with the specific demands of such applications. This thesis proposes a high speed infra-structure network, exclusive for delay sensitive applications. This network, named IXnet, has it\'s origins in experiments with shared routing IXP, traffic studies of a sensitive to delay application and use of network simulator. The use of IXnet may increase the business front for operators and users that utilize sensitive to delay applications, improving the quality of the services provided.
