Full textThere has been a great interest in investigating systemic substances that can positively act on the musculoskeletal system to improve the bone quality thus avoiding osteoporotic fractures. The anabolic androgenic steroids have an important influence on general metabolism and can increase the bone resistance and bone mass. On muscle, it improves sarcopenic conditions. However, there is no consistent investigation of a possible action of these substances on bone callus. Thus, the aim of this study was to evaluate the effect of decanoate of nandrolone on fracture healing and bone quality of young adult male Wistar rats. One hundred animals were divided into 04 groups and 02 subgroups (14 and 28 days). A control group consisted of animals without any intervention (n=17). In the second group, a femoral shaft fracture was performed (n=26). In the third group, the animals received only decanoate of nandronole (n=23). In the fourth group, a fracture in the femoral shaft was performed and associated with administration of the same dose of decanoate of nandrolone (n=26). The fracture created in the femur was obtained by closed method and achieved with the aid of a blunt blade guillotine. After that, the fracture was fixed with a 1.0 mm thick Kirschner wire that was inserted into the medullary canal, and the limb was X-rayed in profile. Ten mg/kg of body mass of decanoate of nandrolone was administered intramuscularly, 02 times a week for 14 or 28 days, depending on the subgroup. After euthanasia, the right femurs were dissected and had the length measured. Bone mineral density and bone mineral content were determined by the dual-energy x-ray absorptiometry method (DXA). The mechanical properties maximum force and stiffness were determined by the twopoint bending test. The bone callus was evaluated microscopically in sections stained with hematoxylin and eosin and examined under ordinary light microscope to calculate the volume of bone callus by the morphometric technique. Other sections were stained in picrosirius red and examined under polarized light for quantification of type I collagen. The statistical significance was set at 5%. There was no significant difference between the animals treated and not treated with nandrolone decanoate for bone mass density, bone mineral content, mechanical resistance and type I collagen, both for the intact bone and for the bone callus. However, the body mass was higher in the groups that received nandrolone decanoate, although without statistical significance. The femur length was greater in the 28th day in the group treated with nandrolone decanoate. Callus mass also had significant increase at 28 days for animals that received nandrolone decanoate. Based on the results and under the experimental conditions and methods of evaluation, the decanoate of nandrolone did not cause significant benefit or harmfull effects both on callus and on bone qualities.

Full textDentre os inúmeros desafios que permeiam a cadeia produtiva de óleos pesados, a fase de transporte merece destaque. Em função de sua elevada viscosidade, os óleos pesados exibem resistência considerável ao escoamento, requisitando mecanismos auxiliares para viabilizar seu transporte mediante dutos. Nesta dissertação, é proposta uma configuração de tubos concêntricos, na qual vapor escoa pelo tubo interno (vaporduto) e óleo pelo espaço anular do oleoduto. São adotadas as abordagens analítica e numérica para investigação dos efeitos da inserção de vapor, geometria, isolamento térmico, qualidade do vapor e extensão do sistema nos seguintes parâmetros: temperatura, viscosidade e pressão do óleo, bem como fração mássica do vapor. Para a primeira abordagem, é empregado o modelo de resistências térmicas associado ao método 𝜖 NTU. Para a segunda, utiliza-se o software Ansys CFX em uma simulação tridimensional em regime permanente. Os desvios apresentados pela abordagem analítica são atribuídos à não incorporação dos efeitos de empuxo, convecção natural e turbulência do vapor, os quais contribuem para um aquecimento não-homogêneo do óleo. Resultados numéricos revelam que a inserção de vapor eleva a temperatura média do óleo em 1,2% e reduz sua viscosidade média e pressão inicial de fluxo em 8,7% e 24,2%, respectivamente. Uma redução de 24,6% na razão entre o raio do oleoduto e do vaporduto resulta em uma temperatura final do óleo 1,2% maior e viscosidade 4,7% menor. A presença do isolamento térmico reduz o fluxo de calor para o meio externo em 78,5%. A redução da qualidade do vapor em 30% causa um aumento da viscosidade média do óleo de 2,4%. Para sistemas mais extensos, a pressão inicial de fluxo requerida aumenta de forma significativa e o vapor úmido apresenta depósitos mais expressivos de líquido na porção inferior do acoplamento. O presente estudo fornece uma análise do acoplamento concêntrico entre vapor e óleo pesado sob diversas condições, explicitando as vantagens e desvantagens qualitativas de algumas estratégias. Em adição, propõe um modelo analítico capaz de prever a temperatura e viscosidade médias do óleo na saída, com desvios máximos de 1,3% e 15,6%, respectivamente, em relação à abordagem numérica.

Full textFracture is a bone discontinuity that can be surgically produced or caused by an impact that exceeds the mechanical strength of bone by initiating a series of systemic events and specific tissue response. Radiological tests are commonly performed in clinical and animal experiments for monitoring the bone healing by providing information about the alignment of the fragments and the evolution of repair. Other techniques for monitoring quality and quantity can be used in experimental animals (histology and mechanical tests) and in animal experiments and clinical studies (computed tomography X-ray, MRI, ultrasound). The 3D microtomography by X-ray is a new monitoring technique for use in animal experiment and with great potential. The quantification of bone repair with new methods has wide application in research on invasive and noninvasive treatment of fractures using animal experiment. The goal of this research was to use the 3D microtomography by non monochromatic X-ray (\'mü\'CT) to evaluate the bone healing in bone defect in the tibia of Wistar male rat weighing approximately 280 g. The defect was produced by a dental drill with high speed. It was established four experimental groups characterized by the use or non use of low intensity pulsed ultrasound (LIPUS, 30 mW/\'CM POT.2\') for the bone defect treatment as well as the duration of the experiment. In group 1 the LIPUS treatment last 14 days, 5 treatment sessions per week. In group 2 the LIPUS treatment was not used and the duration was 14 days. In group 3 the LIPUS treatment last 21 days, 5 treatment sessions per week. In group 4 the LIPUS treatment was not used and the duration was 21 days. In groups 1 to 4, 10 animals were used for evaluation by CT. The evaluation was conducted by CT through software NRecon, Data Viewer, CT-Vol and CT-Analyzer supplied by the microtomography manufacturer (SkyScan, Belgium). No significant statistical differences were found between the results of groups 1 and 2 as well as the results of groups 3 and 4.

Full textThe present dissertation investigates the evolution characteristics of bone regeneration in goat\'s tibia osteotomies by image processing. Digitized radio-graphs of 13 animals were used. They were divided into three groups sacrificed at 30, 45 and 60 days respectively. The fracture healing was performed with the aid of flexible fixation, which often develops indirect regeneration with bone callus. The clinical evaluation is based on the dimensional and mineral density of bone callus measured by one of the existent methods. The evolution of the bone callus relative to the bone thickness and 14 texture parameters evaluated at the fractured site are presented here. Nine of the parameters are characteristics of Haralick (ASM, CONT, CORR, IDM, ENT, VAR, DIAGM, SHADE and PROM) and the others are first order parameters (MEAN, STDEV, KURT, SKEW and ENER). The bone callus behaves as described in literature. Six texture parameters, ENER, ASM, CONT, IDM, ENT and DIAGM had no relation with regeneration. The CORR parameter experesses the quality of the image. SHADE and PROM parameters mark the ontour of the images. SKEW, KURT and STDEV have a similar behavior once they separete osteotomy from medular in the initial images. The VAR and MEAN parameters show a commom variation among images along the time. This pattern represents the evolution of regeneration and distinguishes bone concentration at osteomotmy site and therefore its rigidity. Texture parameters are capable ofcharacterizing bone regeneration in a noninvasive way for an automatic classification system.

Full textX-ray microtomography (uCT) provides quantitative and three dimensional measurements of the callus structure and these measurements could potentially be related to callus strength. The assessment of bone repair through new methodologies has important application in animal investigations regarding invasive or non invasive technologies for the stimulation of bone healing. The aim of this investigation was the use of \'mü\'CT for the assessment of bone repair in a rat femur bone defect. Thirty male Wistar rats weighting about 300g were divided in three experimental groups with 10 animals on each group. The animals were anesthetized and a circular hole with a 1.2 mm diameter was generated at the medial region of the left femur using a dental drill. At the 7th, 14th and 21st day after surgery the animals of experimental groups 1, 2 and 3, respectively, were sacrificed and the left femur excised. The femurs were wrapped in gauze immersed in phosphate-buffered solution and stored in a plastic bag at -20ºC until the analysis by microtomograph. The femurs were scanned by the 1172 microtomograph (SkyScan, Belgium). The softwares NRecon, Dataviewer, CT-Analyzer and CT-Vol, provided by the microtomograph manufacture, were used for the following assessments: a) visual examination of the femurs microtomographic reconstructions using transversal, coronal and sagittal sections; b) segmentation of the bone callus in the reconstructions using an image processing algorithm to quantify the parameters total bone callus volume (TV), volume of the mineralized bone callus (BV), the ratio BV/TV and the volumetric bone callus mineral density (BMD); c) 3D rendering of the bone callus. The statistical analysis of the measured parameters was performed by the Student t test with a level of significance p<0,05. There was a statistically significant increase in the mean values of the parameters BV/TV and BMD in the comparison of experimental groups 1 and 2. The comparison between groups 2 and 3 was not statistically significant. Results are according to bone physiology data from literature although the image processing algorithm used needs some adjustments to get better results in bone callus segmentation in ROI.

Full textUltrasound transmission in human bodies has been studied for several decades in order to facilitate diagnosis. It has also been used to evaluate bone density and to diagnose early osteoporosis and future fracture risks. For this study, a system to generate, receive and amplify ultrasonic signs for speed of sound assessment and broad band ultrasound attenuation (BUA) was developed. Transmission of ultrasonic signals was performed by coupling using ultrasound gel and water (acoustic tank) and the sample placed between two transducers, one for transmission and the other for reception. Due to the high rate of the dispersion of ultrasonic measures, some reference material having the characteristics of the speed of sound and broad band ultrasound attenuation, similar to the heel bone that will be used for equipment calibration and follow-up of bone measure will have to be found. Ultrasonic parameters were used to evaluate bone consolidation (tibia of a sheep), in different periods and several kinds of fractures. Temperature and reproducibility using different materials were used to customize the system. Measures of volunteers\'s heel bone speed and broad band ultrasound attenuation showed results consistent with the ones from literature. Several analyses with little changes in geometric, signal and transducer frequency conditions were performed in order to observe their influence on attenuation and speed measures. Those steps were carried out in order to try to relate the variations in attenuation measures to those obtained by other authors.

Full textThe genetic transformation can contribute substantially with the bean (Phaseolus vulgaris L.) breeding, allowing the introduction of genes to improve productivity and its stability. The transformation methodology of bean, now available (biolistic in embryos), is not efficient, which prevents its use in bean breeding programs. A reproducible and effective method of plant regeneration, from cells or tissues is essential in genetics studies and plant breeding, involving the genetic engineering. The transformation methods will only work if we can previously establish an efficient plant regeneration protocol from tissues with potential for transformation. The aim of this work was to develop an efficient transformation protocol of bean via Agrobacterium. The first step was to establish an efficient system of plant regeneration from callus, followed by the establishment of a transformation methodology via Agrobacterium.

Full textPlant tissue culture has shown to be effective in multiplication and conservation of plant genetic resources. The genipap (Genipa americana L.), from the Rubiaceae family stands out for its plurality of uses, either as a forest species, fruit production or in traditional medicine. This study was divided into two parts. The first study investigated the effects of NAA concentrations (0.0, 0.2, 0.4 and 0.6 mg L-1) in combination with 1.0 mg L-1 of BAP in the morphogenesis of genipap zygotic embryos and embryonic axis of Núcleo Bandeirante (NB) access. At 30 days, it was observed that the in vitro regeneration of genipap is possible from the conversion of whole embryos in a medium supplemented with 0.6 mg L-1 NAA. The largest shoot length, number of leaves and roots were obtained in the medium NAA free. The progressive increase in the concentration of NAA induced the formation of compact calli, especially in the embryonic axis segment. Regeneration via direct organogenesis was not observed. The second part aimed to determine the effect of 2,4-D (0.0, 2.0, 4.0, 6.0 and 8.0 mg L-1) for induction of callus from leaf and nodal explants of genipap and characterize the dynamics of kinetics growth. The best induction response occurred at a concentration of 2.0 mg L-1 2,4-D and 1.77 mg L-1 BAP for leaf explants of NB, SA and SAL accesses, with emphasis on access SA who presented a biomass of 0.2223 g after 60 days of cultivation. However, for callus obtained from nodal segments, the response due to 2,4-D was different between the accesses. The fresh weight increase was higher for NB and SA at concentration 4.0 mg L-1 2,4-D and SAL, at 2.0 mg L-1 2,4-D. The kinetics growth was established from the fresh weight of callus at intervals of 10 days. The growth curve of leaf and nodal explants callus showed a linear pattern and only three stages of growth were observed: lag, exponential and linear. Calli of SA nodal segment should be transferred to a new culture medium after 40 days of cultivation.
A cultura de tecidos vegetais tem-se mostrado eficaz na multiplicação e conservação de recursos genéticos vegetais. O jenipapeiro (Genipa americana L.), da família Rubiaceae destaca-se pela sua pluralidade de usos, seja como essência florestal, na produção de frutos ou na medicina tradicional. Esse trabalho foi dividido em duas partes. A primeira objetivou estudar os efeitos das concentrações de ANA (0,0; 0,2; 0,4 e 0,6 mg L-1) em combinação com 1,0 mg L-1 de BAP na morfogênese in vitro de embriões zigóticos inteiros e eixos embrionários de jenipapeiro do acesso Núcleo Bandeirante (NB). Aos 30 dias, observou-se que a regeneração in vitro foi possível a partir da conversão de embriões inteiros em meio MS suplementado com 0,6 mg L-1 de ANA. O maior comprimento da parte aérea, número de folhas e de raízes foram obtidas em meio isento de ANA. O aumento progressivo na concentração de ANA levou a formação de calos compactos, principalmente no segmento eixo embrionário. A regeneração via organogênese direta não foi observada. A segunda parte buscou determinar o efeito do 2,4-D (0,0; 2,0; 4,0; 6,0 e 8,0 mg L-1) na calogênese de explantes foliares e nodais de jenipapeiro e caracterizar a sua dinâmica de crescimento cinético. A melhor resposta de indução ocorreu na concentração de 2,0 mg L-1 de 2,4-D e 1,77 mg L-1 de BAP para os explantes foliares dos acessos Núcleo Bandeirante (NB), Sabinópolis (SA) e Salvaterra (SAL), com destaque para o segundo, que apresentou uma biomassa de 0,2223 g, aos 60 dias de cultivo. No entanto, para calos obtidos a partir de segmentos nodais, a resposta de indução em função do 2,4-D foi diferenciada entre os acessos testados, sendo superior para os acessos NB e SA na concentração de 4,0 mg L-1 de 2,4-D e para o acesso SAL, na de 2,0 mg L-1 de 2,4-D. A cinética de crescimento foi estabelecida a partir da massa fresca dos calos em intervalos de 10 dias. A curva de crescimento de calos de explantes foliar e nodal apresentou um padrão linear, sendo detectada apenas três fases de crescimento: lag, exponencial e linear. Calos do acesso SA obtidos de segmento nodal devem ser transferidos para um novo meio de cultura ao 40º dia de cultivo.

Full textIn this work, the Monte Carlo method is applied to the absorption-line-blackbody distribution function (ALB distribution function) to consider the effect of the spectrum in the calculation of radiation heat transfer in participating media. The methodology combines the flexible, robust Monte Carlo method with the ALB distribution function, which simultaneously incorporates a large number of the spectral lines. The proposed implementation establishes a simple, direct relation between the ALB distribution function and the Monte Carlo cumulative distribution function, which makes it easier to implement the technique and leads to computational efficiency. The verification of the methodology was accomplished with the comparison of the obtained results with a set of solutions that are presented in the literature, as obtained with the weighted-sum-of-gray-gases based on the spectral lines and with the line-by-line integration, considering non-homogeneous and non-isothermal media composed of water vapor, carbon dioxide and non-participating species. The Monte Carlo method applied to the ALB distribution function was employed to obtain various results to evaluate the approximations that arise from the weighted-sum-of-graygases, which is of large application in the radiation heat transfer in participating media. The solutions include both one-dimensional and cylindrical enclosures having isothermal and nonisothermal, homogeneous and non-homogeneous media, composed of water vapor, carbon dioxide and non-participating species. For the cylindrical geometry, the temperature and the concentration distributions were based on distributions that can be found in the interior of combustion chambers. The analysis showed that both the approximations due to the concentrations of the chemical species and due to the modeling of the radiation spectrum can lead to considerable errors, showing the importance of using more sophisticated models. To increase the efficiency of the Monte Carlo method, it was also developed the model of multispectral energy bundles, which considers that the energy of the bundles is distributed in the different wavelengths. This model reduced the computational time in 50 % for the proposed test case.

Abstract: Newer designs for more efficient and effective ovens require the capability of modeling the radiative heat transfer among surfaces of different finishing whose radiation exchange is blocked by the presence of cooking trays. Here, a Monte Carlo simulation of the thermal radiation exchange among surfaces of a domestic oven cavity blocked by a cooking tray is developed in order to calculate view factors and net radiation heat transfer rates. The Monte Carlo technique provides the required flexibility to support the future analysis of more intricate designs. Initially, a ray tracing algorithm to obtain the view factors is tested and validated for different configurations. A convergence analysis of the accuracy and dispersion of the results is done by comparison with available solutions. A mean view factor of 100 runs of the algorithm with 10.000 rays emitted resulted in error smaller than 0.4 % when compared with analytical solutions and standard deviations relative to mean less than 0.0050 in all test configurations. The algorithm is also implemented for multiple view factors of the blocked rectangular cavity adding a multi-zones approach to tracing rays in geometry with obstacles. The simulation shows high accuracy as well reaching values smaller than 0.3% for 1 run of ?10?^7 rays. Then, a heat transfer algorithm is developed assuming that the surfaces are gray and using a random absorption probability function to model the global hemispherical absorptivity of the surfaces. The boundary conditions for radiative simulations are provided by measurements of temperature in a conventional oven cavity. The algorithm for radiative exchange is validated with the thermal resistances network method reaching deviations smaller than 4% for 60000 rays emitted from each surface of the cavity. The standard deviation relative to mean fluxes of 50 runs converged to 1 W/m^2 in all surfaces when ?10?^6 rays are used. Following, a study of the effects of surface finishing in the non-blocked closed oven cavity is developed. Finally, the gas burner oven is compared with available results of an electric heating elements oven, showing a higher radiation exchange with the radiation source surface of cavity but lower uniformity over the load surfaces than that reached with electrical heating elements. Concluding remarks and recommendations as well as guidelines for more efficient and effective ovens design are given.
Introdução: Novos projetos para fornos domésticos mais eficientes requerem a capacidade de modelar a transferência de calor por radiação entre as superfícies que formam a cavidade do forno. Essas apresentam diferentes acabamentos e a sua transferência de calor líquida por radiação é afetada pela presença de superfícies que causam sombreamento das demais, como na cocção de alimentos. Objetivos: Nesse trabalho, o método de Monte Carlo é utilizado para obter os fatores de forma da radiação e a transferência de calor líquida entre as superfícies que formam a cavidade de um forno de cocção doméstico, com e sem a presença de uma forma para a cocção de alimentos. O Método de Monte Carlo proporciona a flexibilidade necessária para a modelagem de projetos de cavidades com geometrias complexas. Materiais e Métodos: Com esse objetivo, inicialmente desenvolve-se um algoritmo para o rastreamento de feixes de radiação com a finalidade de obter os fatores de forma. Os valores obtidos são comparados com as soluções algébricas disponíveis para superfícies mais simples e com fatores de forma calculados pelo método de integração numérica de superfície para as geometrias que apresentam sombreamento. Resultados: Os fatores de forma obtidos da média de 100 realizações com a emissão de 10000 feixes cada uma resultaram em diferenças menores que 0,4 % quando comparados com aqueles obtidos das relações algébricas e o método de Monte Carlo convergiu com desvio padrão menor que 0,0050 para todas as configurações testadas. O algoritmo foi também aplicado para um modelo multi-zonas para tratar geometrias com sombreamento. As simulações resultaram em diferenças menores que 0,3 % para uma realização com a emissão de 10 [na potência] 7 feixes. A transferência de calor por radiação foi então modelada usando uma função de distribuição de probabilidade para modelar a absortividade hemisférica total das superfícies. As temperaturas medidas nas superfícies de um forno a gás operando em regime permanente foram utilizadas para calcular as taxas de transferência de calor líquidas por radiação. Os resultados obtidos pelo método de Monte Carlo foram comparados com os valores calculados pelo método de resistências térmicas e foram encontradas diferenças menores que 4 % quando 60000 feixes são emitidos a partir de cada superfície. O desvio padrão da solução pelo método de Monte Carlo para 50 realizações utilizando 10 [na potência] 6 feixes em cada uma convergiu para 1 W/m² para todas as superfícies. O efeito das emissividades das superfícies foi então analisado. Finalmente, o aquecimento a gás foi comparado com o aquecimento elétrico, usando as mesmas temperaturas superficiais. Conclusões: O método de Monte Carlo resultou em diferenças menores que 0,4 % quando comparado com soluções algébricas para fatores de forma, enquanto que o cálculo de transferência de calor líquida resultou em diferenças menores que 4 % quando comparado com método de resistências térmicas. Portanto, o algoritmo desenvolvido apresenta desempenho adequado. A redução da emissividade da porta resulta em maior uniformidade no campo de radiação no interior da cavidade, além de resultar em menor perda de calor pela porta para o ambiente. Finalmente, foi encontrada maior troca de calor por radiação a partir do aquecimento a gás quando comparado com o aquecimento elétrico, porém, como menor uniformidade no campo de radiação interno à cavidade. Recomendações gerais sobre o aumento da eficiência de cavidades de fornos domésticos são elencadas ao final do trabalho.

In Cape Verde, an ex-colony of Portugal who became independent in 1975, the political disputes among groups that in any way see themselves as true nationalists or as inheritors of the nationalist authentic trajectory are recurrent. In opposition to this velleity of the Capeverdean political actors, some scholars of nationalism suggest the inauthenticity of the african nationalist constructions, since they were supposedly forged from mimetic processes of modular forms produced in European countries. In both cases, political and theoretical, one operates from the exploration of frontier lines, that make radical the differences between the agents and contexts that are reificated and situated in binary terms, and define their mutual distance, their self-enclosement and, as a result, their non-exchangeability. The present study, considering the colonial situation, examines the influence of colonial conflicts (social, political and symbolic), in the political-discursive redefinition of the colonizers, in the subversion of intranational boundaries and in the emergence of new nations from the colonies. It is basically assumed that colonialism not only alters the political-discursive structure of the colonizers but also creates its own nationalist (re)production and customs mechanism. In other words, despite its constitutively and intrinsically asymmetrical character it does not fix definitely the boundaries which it builds or, sometimes, exacerbates. On the contrary, in its interior, there is place for peculiar national operations, leading to reinterpretations, (re)negotiations or (re)definitions of belongings, loyalties and national representations. In this sense, based upon the rescue of the interactional dynamic and the emancipation of political strategies of specific political actors, one will argue, against the imitation thesis, that in the social fields included in the colonialism the national operations begin to take form from the colonial practices, when the supposedly universal and inclusive nation is unilaterally appropriated as basis of domination. In the Capeverdean case, that implies an reanalysis of the nationalist question, whether by the recuperation of the actors and practices traditionally expelled from the official national(ist) imaginary, whether by the intersection of the constructions called nationalists with other correlated phenomena - specially, the "crioulização", the "diasporalização" and the "cosmopolitização" - which may confuse their intelligibility, certitudes and supposedly consecrated frontiers.

Full textThis Ph. D thesis proposes to revisit the artistic career of the 17th century painter Carlo Saraceni, from the appearance of the 1968 discoveries of this painter, when the first monographic study was dedicated to Saraceni. New paintings and documents infact have emerged in the last thirty years of «Carlo Venetiano» and even during the rendition of these work, it was attempted to recreate through the complete revision of critical essays dedicated to him, an updated biographic profile. The critical case of Carlo Saraceni is particularly interesting since the focal point of his work within the caravaggesque movement has played a significant role in understanding the ladder along with understanding some very important 17th century French painters, as well as Spanish, Flemish, and Italians that are credited to Saraceni’s craft. Therefore after having examined the initial formation of the painter in Venice and the artistic examples that Saraceni may has seen in this city, I have studied the most noted activity of the painter conducted in Rome, that has been carried out by evaluating the exchanges between Saraceni and important clients and painters that were in the city at that time. Analysed as well is the return of the painter in Venice in 1620 along with a chapter dedicated to evaluating Saraceni’s followers and the expansion of his craft in Italy, France, Spain, and countires of Northern Europe, through certain artists connected to Saraceni. Finally, a chapter dedicated to the scarce sketches of the artist in addition to the complete catalogue of his works, and an appendix of documents has been included with a list of his dispersed works

Full textA maior parte das empresas moveleiras existentes no Brasil (97%) são constituídas por Micro e Pequenas Empresas (MPEs). A produção é essencialmente de móveis produzidos por encomenda e sob medida e empregam processos de fabricação semi-artesanais. Os processos de produção não são sustentáveis, o que se traduz em desperdícios e em um grande volume de resíduos. Os resíduos compostos, principalmente, por restos de madeira reconstituída (principalmente de MDF) muitas vezes são eliminados de modo irregular no espaço público, queimados a céu-aberto ou em fornos de padaria. O descarte irregular de resíduos constitui uma ameaça para a saúde pública e para o ambiente, degrada a imagem das periferias e acentua as assimetrias sociais. As ações de fiscalização e de penalização têm sido ineficazes, pelo que urge repensar o problema envolvendo a geração e a disposição de resíduos dessas empresas. A “pulverização” de MPEs do setor por um território muito vasto e a reduzida dimensão dessas estruturas produtivas têm dificultado as ações de sensibilização para uma mudança do paradigma produtivo, porque essas empresas estão, na sua maioria, demasiado preocupadas com a sua subsistência. Essa investigação objetivou identificar e minimizar os desperdícios e o descarte irregular de resíduos por parte das MPEs moveleiras, reduzindo os impactos ambientais, econômicos e sociais provenientes da produção de mobiliário personalizado por meio do design estratégico sustentável. Em termos metodológicos, foi utilizada a Investigação Ativa (Active Research), integrada com um processo participativo entre os stakeholders. O estudo de campo conduziu-se em um contexto local, na região do Triângulo Mineiro, Minas Gerais, Brasil. A partir do diagnóstico realizado em cinco MPEs de mobiliário personalizado da região foi desenvolvido um modelo que propõe a melhoria contínua de produtos, serviços e processos produtivos por meio de um conjunto de estratégias, diretrizes e ferramentas de design estratégico sustentáveis que podem ser implementadas de maneira progressiva. O modelo foi avaliado por um painel de dez especialistas e um plano de ação foi determinado visando sua inserção em uma empresa piloto. O modelo designado Projeto Caco foi parcialmente implementado em uma MPE de mobiliário. Como resultado parcial da investigação verificou-se que em consequência da estratégia de negociação e articulação de interesses públicos e privados promovida pelo Projeto Caco, 60 marcenarias da região do Triângulo Mineiro passaram a destinar os resíduos de modo ambientalmente correto em um aterro industrial licenciado. Os resultados demonstraram que o modelo é um recurso para reduzir os desperdícios e os impactos sociais, ambientais e econômicos das MPEs moveleiras, para incentivar a destinação correta de resíduos, reduzir a degradação do espaço público, gerar economia aos cofres públicos municipais e reduzir os impactos para a sociedade afetada pelo descarte irregular de resíduos.
ABSTRACT: Most of the furniture companies in Brazil (97%) are Small and Medium-sized Enterprises (MSEs). The production is essentially made-to-order and custom-made furniture and applies semi-craft manufacturing processes. Production processes are not sustainable, resulting in waste and a large volume of waste. Residues composed mainly of reconstituted wood residues (mainly MDF) are often disposed irregularly in the public space, burnt in open skies or in bakery ovens. Irregular waste disposal poses a threat to public health and the environment, degrades the image of the peripheries and accentuates social asymmetries. The inspection and penalty actions have been ineffective, so it is urgent to rethink the problem involving the generation and disposal of waste from these companies. The "spraying" of MSEs in the sector over a very wide territory and the small size of these productive structures have made it difficult to raise awareness of a change in the productive paradigm because these companies are, for the most part, too preoccupied with their subsistence. The objective of this investigation was to identify and minimize the waste and the irregular disposal of waste by furniture MSEs, reducing the environmental, economic and social impacts from the production of customized furniture through sustainable strategic design. In methodological terms, Active Research was used, integrated with a participatory process among stakeholders. The field study was conducted in a local context, in the region of Triângulo Mineiro, Minas Gerais, Brazil. Based on the diagnosis made in five MSEs of customized furniture in the region, a sustainable strategic design model was developed, consisting of a set of strategies, guidelines and tools, which proposes the progressive improvement of products, services and production processes. The model was evaluated by a panel of ten experts and a plan of action was determined aiming its insertion in a pilot company. The model named Project Caco was partially implemented in a furniture MSE. As a partial result of the investigation, it was verified that as a consequence of the strategy of negotiation and articulation of public and private interests promoted by the Caco Project, 60 woodworkers from the region of the Triângulo Mineiro began to direct the waste in an environmentally correct way in a licensed industrial landfill. The results demonstrated that the model is a resource to reduce the waste and social, environmental and economic impacts of the MSEs, to encourage the correct disposal of waste, reduce public space degradation, generate savings to municipal public coffers and reduce impacts to the society affected by the irregular waste disposal.

This research investigated the dance piece Caldo da Cana which premiered in Jo?o Pessoa-PB, in September 1984. It problematizes theoretical and practical way to make dance history, investigating this possibility through the dance itself. Arises from the fact that the dance has specific characteristics that can not be neglected by the historical account. In this sense, it was initiated by the raising of a theoretical framework that speaks to the indicated issues and unfolds through a field study, which included collecting testimonies from people who participated in the show, documentary research, gathering material traces and finally consists a practical part by transposing elaborated historical knowledge into the body through a creative process, resulting on this moment, in the construction of a duo dance

Full textPurpose: The present study aims to verify the effect of high and low dose of methotrexate (MTX) treatment on bone repair of mandibular fractures in rats. Methods: The experimental model employed consists in creating a defect in rat mandible, similar to a fracture. Eighty rats were distributed in 4 groups of 20 animals that received, intraperitoneally: saline (1 ml, after surgery); dexametazone (DX, 0.15 mg/Kg, one dose at surgery); high dose MTX (1.6 mg/Kg, weekly); low dose MTX, (0.25 mg/Kg, weekly). Groups of five animals were sacrificed on the 1st, 7th, 15th and 30th day after surgery. Mandibles were submitted to radiographic analysis to measure the distance between bony edges and the area of osteotomy. Histopathological evaluation was performed in digitalized images using an analyzer software to examine cartilage and bone formation. Results: The treatments did not alter any evaluated parameters on days 1 and 7 after surgery. Control animals sacrificed on the 15th day after surgery had a reduction of the distance between bony ends and in the area of osteotomy, as well as a great increase in cartilage formation. The pattern of these parameters in animals treated with low dose MTX and DX did not differ from control group. However, animals treated with higher dose of MTX kept increasing the distance between bony ends and the area of osteotomy, and the increase in cartilage formation was practically inexistent. On the 30th day after surgery, control animals had pratically recovered the fracture region, as well as those treated with low dose MTX. The group treated with higher dose MTX and DX still had an open bone defect. Conclusions: This study clearly shows that low dose MTX did not affect bone healing of mandibular fractures in rats, in contrast to a higher dose, which promotes impairment of bone regeneration.
