Повний текст джерелаThis dissertation proceeds to analyze and delineate the transformation effected by Copernicus, when the formed his hypothesis of the motion of the earth and proponed it with specific reference to the heliocentric system. I consider the various contexts, historical, scientific (both astronomical an mathematical) and cosmological, within which this hypothesis of the earth's motion took shape. The two subsequent sections set out analysis of book I of de revolutionibus, with particular attention to the logical, cosmological, and rhetorical form of the argument for the hypothesis of the earth's motion. The is followed by the dissection of the task, Copernicus the set himself in the following five books of de rev. , i. E. Of recasting his hypothesis in terms of the theoretical current scientific thought, as regards the astronomical motions of the earth and the planetary motions, while showing the manner in which the thesis of the motion of the earth is implemented equally in a philosophical and cosmological sense, as well as in the astronomical and mathematical domain. The sixth section then shows how this thesis was taken up, subjected to criticism and given a new twist by Tycho Brahe, on observational and cosmological grounds; and to what use it was put by the founding fathers of modern astronomical and physical science : Kepler and Galileo. The final two sections examine the epistemological appreciations of the Copernican thesis, and the philosophical impact of Copernicus as figure by referring the various philosophical systems to a thesis expounding a new form of reflexivity : the observer being required to take a standpoint external to his own position to achieve self-knowledge, this makes it possible for the category of subject to come into its own, this being the fundamental attainment of the Copernican revolution

Повний текст джерелаHydrological monitoring is important for mining activities. For example, a change of hydrological conditions might indicate an impact of mining activities in the neighborhood. The detection of such impacts is a relevant task. The observed areas are usually large, and a cyclic manual inspection is often very expensive. Therefore, remote sensing is suitable to do a monitoring of such areas in order to detect different processes. Changes in soil moisture can be detected by looking into backscattering characteristics of radar images, spec-trum analysis of optical images is able to assess vegetation vitality. The interpretation of multispectral data is able to show new and enlarged water bodies. Furthermore, ground deformation caused by hydrological changes (for example uplifts as a consequence of increasing pit water) can be detected and measured via radar interferometry. A monitoring with such methods is possible for large areas. As remote sensing sensors the Copernicus-satellites Sentinel-1 and 2 are suitable with the big advantage of providing data in short cycles operationally and free of charge. In this paper various monitoring components are described

Повний текст джерелаThe rate at which global climate change is happening is arguably the most pressing environmental challenge of the century and it affects our cities. Over half of the world’s population lives in cities and the urban areas are in the forefront of the climate change issue. Climate change exerts added stress on urban areas through increased numbers of heat waves threatening people’s wellbeing and in many cases human lives. Earth Observation (EO) systems and the advances in remote sensing technology increase the opportunities for monitoring the urban climate and the thermal behaviour of cities. At the time of this thesis, the first two of a large constellation of European Satellites, the Sentinels, have been launched. The Sentinels constitute the first series of operational satellites for Copernicus, a programme launched to provide data, information, services and knowledge that support Europe's goals regarding sustainable development and global governance of the environment. To this end, the Sentinels will provide a wealth of EO data for monitoring the urban climate. This PhD thesis, examines the exploitation of EO data for monitoring the urban climate, with particular focus on satellite data and the Copernicus Sentinels. State-of-the-art urban remote sensing methods are reviewed and advances are proposed for filling the knowledge gaps in developing EO data products to assist the monitoring of urban climate. The thesis is divided in three thematic parts, each of which presents a complete method for addressing urban climate related issues and a last part that illustrates their connection through examples. More specifically, the first part of this thesis deals with the mapping of the urban surface and its characteristics, using EO data. Remote sensing methods for characterizing the urban surface cover are reviewed and a new method is proposed adjusted for urban studies, which accounts for the non-linear mixture of spectral radiances in the urban canyon. The proposed method is based on machine learning techniques and synthetically mixed training data and it is specifically developed for multispectral sensors, to make it easily adaptable and applicable to Sentinel data. The second part of this thesis examines the exploitation of EO data for discriminating between the different local climate zones. Cities are not only warmer than the surrounding rural areas, but there are temperature variations in different parts of the city. EO data provide a valuable source of information for outlining areas with distinct thermal behaviour, i.e. local climate zones. Remote sensing methods are carefully reviewed and applied to estimate spatial distributions of parameters related to the city climate. A consolidated methodology then combines the separate EO products for identifying the zones with homogeneous thermal behaviour. The third part of this thesis focuses on thermal EO data and remote sensing methods. To capture the intra-urban variations of temperature, EO data of high spatial and temporal resolution are necessary, but no current of forthcoming satellite provides them. Moreover, only one from the series of Sentinel satellites carries a thermal sensor of low spatial resolution. To overcome the limitations of the resolution trade-off, a methodology is developed and applied that exploits a synergy between high resolution optical and low resolution thermal satellite measurements with ultimate goal daily local scale land surface temperature estimates. In conclusion, the last part of this thesis presents a wrap-up of the aforementioned methods with demonstration examples. The use of the combined EO products in assessing the urban climate is demonstrated and the significance of the developed methods is illustrated. Sentinel data can support studies of urban climate and this thesis highlights this need and proposes methods for deriving suitable products for assisting the monitoring of our cities and their climate.

Повний текст джерелаCopernicus showed in his de revolutionibus that the earth must have a motion because it is not reasonable to suppose that the immense starry sphere should revolve in twenty-four hours. Thus, the apparent motion of the world becomes a mere illusion, and it is no longer evident to think that the universe is closed as a perfect sphere. Then, the ancient argument in favour of the finity of the universe, (founded on the impossibility of a rotating inifinity) looses all its relevance and the question of cosmological infinity has to be examined anew. In spite of copernicus' attachment to cosmological finitism, his new astronomical system leads him to raise in new terms the question of cosmological infinity : "perhaps, it will be easier to understand this nothingness outside the heavens if we assume them to be infinite". Thus, the new copernican immensity made possible the transition from a closed world to an infinite universe. During the 17th century most of the greatest scientists and philosophers were supporters of cosmological infinity, whereas in the following century the interest for that problem considerably diminished as the number of the infinitists. The thesis analyses the philosophical reasons of this intellectual withdrawal of cosmological infinitism and also its most important exceptions (as kant'theory of the heavens). This work studies the emergence of cosmological infinity in its different meannings and consequences since renaissance cosmological revolution. The concept of cosmological infinity leads to the idea of an actual infinity, because the universal boundless space refers necessarily to a complete totality. The idea of an infinite universe introduced in the field of scientifical knowledge the concept of an actual infinity. Whereas the parts of time are successive, the parts of a boundless consmological space have a siml

Повний текст джерелаThis dissertation has as subject the relation of Copernicus system with the Bible; a crucial question that may be analyzed in Galileo s Letter to Cristine of Lorene, wrote in 1615, in which this subject is treated by the celebrated Florentine. At first, some observations of Galileo are considered (solar spots, phases of Venus and Jupiter satellites) which gave credit to the thesis of Nicolaus Copernicus, who placed Sun in the center of Universe and made Earth to turn around itself and around the Sun. This thesis was introduced more than one half century before, but without proofs to support it. The observacional discoveries of Galileo provided support for the copernican system, being argued the character of this support: a rigorous proof (necessary demonstration) or endorcement of an hypothesis saving the phenomena . We endeavor to analyze the Letter of Galileo to Cristine of Lorene, stressing the strategies used by Galileo to show the agreement of the copernican system with the Bible; stressing also as Galileo conceives the study of the book of Nature and the interpretation of the Bible. For Galileo, Nature as much as Sacred Scripture are works of God; they are, therefore, two books without error and cannot contradict one another; however, Nature and Scripture are two books written in different languages, with different purposes, not being able to be read in the same way
Esta dissertação tem como objeto a relação do sistema de Copérnico com a Bíblia; questão crucial que pode ser analisada na Carta a Cristina de Lorena, de Galileu, escrita em 1615, na qual tal tema é abordado pelo célebre florentino. São consideradas de início algumas observações de Galileu ( manchas solares, fases de Vênus e satélites de Júpiter) que davam crédito à tese de Nicolau Copérnico, que colocava o Sol no centro do universo e fazia a Terra girar em torno de si mesma e ao redor do Sol. Tese introduzida mais de meio século antes, mas sem provas para fundamentá-la. As descobertas observacionais de Galileu proporcionaram sustentação para o sistema copernicano, discutindo-se o caráter desta: prova rigorosa (demonstração necessária) ou fundamentação de uma hipótese capaz de salvar os fenômenos ?. Procuramos analisar a Carta de Galileu a Cristina de Lorena, destacando as estratégias utilizadas por Galileu para mostrar o acordo do sistema copernicano com a Bíblia; destacando também como Galileu concebe o estudo do livro da Natureza e a interpretação da Bíblia. Para Galileu, tanto a Natureza como a Sagrada Escritura são obras de Deus; são, portanto, dois livros desprovidos de erro e não podem se contradizer; no entanto, a Natureza e a Escritura são dois livros escritos em linguagens diferentes, com finalidades diferentes, não se podendo lê-los da mesma forma. As fontes primárias utilizadas foram as cartas de Galileu que se referem à relação do sistema copernicano com a Bíblia, principalmente a carta a Cristina de Lorena. Também utilizamos textos da época que foram úteis para a compreensão do confronto entre ciência e religião no caso em questão

Повний текст джерелаThe aim of the present work was to evaluate the adsorptive capacity of carnauba straw in natura for removal of the textile dyes methylene blue and crystal violet, in aqueous solutions. Initially, the adsorbent was crushed, washed, dried at 50 ° C and sieved, so that the size of the grains come between 0.088 0.177 mm. The thermogravimetric study showed that the material begins to suffer from degradation at 150° C. The x-ray diffraction identified in the matrix and presents the amorphous with an index of crystallinity 31,80 % character study with infrared spectroscopy reveals peculiar peaks of lignocellulosic materials. For pHzpc obtained a value close to 5.5. It was observed that the pH interferes with adsorption of both dyes studied. In kinetic study, performed at 25 ° C was observed for the two dyes close to the equilibrium time of 120 min and a mechanism compatible with the linearized equation of second order (R2 = 0.9999). The model was also applied and intraparticle three stages were noted indicating that the diffusion and equilibration of the dyes with the adsorbent. The isotherms were constructed at temperatures from 25 to 55 ° C. The increase in temperature caused an increase in the adsorbed amount of crystal violet and a decrease in adsorbed amount of methylene blue. The isotherms models of Langmuir, Freundlich and Sips were applied in the evaluation of experimental results, and are best described by the Sips model (R2 = 1.0000) for the two dyes. Finally, the thermodynamic parameters showed negative enthalpy change for methylene blue (H = - 1,929.10-2 kJ mol-1), and positive for the crystal violet (H = 2,259.10-2 kJ mol-1), entropy increase and the free energy decrease with increasing temperature, for both the methylene blue as for the crystal violet.
O presente trabalho teve como objetivo avaliar a capacidade de adsorção da palha da carnaúba in natura para remoção dos corantes têxteis azul de metileno e cristal violeta, em de soluções aquosas. Inicialmente o adsorvente foi triturado, lavado, seco a 50ºC e peneirado, de modo que o tamanho dos grãos ficasse entre 0,088 0,177 mm. O estudo termogravimétrico mostrou que o material começa a sofrer degradação a partir de 150ºC. A difratometria de raio-x identificou que a matriz em estudo apresenta caráter amorfo com um índice de cristalinidade de 31,80 % e a espectroscopia na região do infravermelho revelou picos peculiares de materiais lignocelulósicos. Para o pHzpc obteve-se um valor próximo de 5,5. Observou-se que o pH interfere na adsorção dos dois corantes estudados. No estudo cinético, realizado a 25ºC, foi observado para os dois corantes o tempo de equilíbrio próximo de 120 min e um mecanismo compatível com a equação linearizada de segunda ordem (R2 = 0,999). O modelo intrapartícula também foi aplicado e três etapas foram notadas indicando a difusão e o equilíbrio dos corantes com o adsorvente. As isotermas foram construídas nas temperaturas de 25 a 55ºC. O aumento da temperatura proporcionou um aumento na quantidade adsorvida do cristal violeta e uma diminuição na quantidade adsorvida do azul de metileno. Os resultados revelaram uma quantidade máxima adsorvida igual a 0,294 mmol g-1 para o azul de metileno a 25ºC e 0,399 mmol g-1 para o cristal violeta a 55ºC. Os modelos de isotermas de Langmuir, Freundlich e Sips foram aplicados na avaliação dos resultados experimentais, sendo mais bem descritos pelo modelo de Sips (R2 = 1,000) para os dois corantes. Finalmente, os parâmetros termodinâmicos mostraram variação de entalpia negativa para o azul de metileno (H = - 1,929.10-2 kJ mol-1) e positiva para o cristal violeta (H = 2,259.10-2 kJ mol-1), aumento de entropia e diminuição de energia livre com o aumento da temperatura, tanto para o azul de metileno como para o cristal violeta.

O estudo visou (1) desenvolver marcadores microssat?lites (SSR) para Copernicia prunifera, e (2) caracterizar o padr?o demogr?fico e a estrutura gen?tica espacial (EGE) entre est?gios de vida por meio de iniciadores ISSR. Foram desenvolvidos 17 pares de iniciadores SSR. A estrutura demogr?fica e EGE foram avaliadas em uma parcela com ?rea de 0,55 ha em ?rea natural, onde todos os indiv?duos foram georreferenciados (n = 161). As an?lises moleculares dos SSR indicaram que todos os pares de iniciadores constru?dos, quando submetidos ? PCR, amplificaram. Estes apresentaram tamanhos de pares de bases variando entre 113 e 250 bp. As an?lises demogr?ficas mostraram padr?o de distribui??o espacial agregado nas primeiras classes de dist?ncia, aleat?rio entre 40 e 50 m e segregado em dist?ncias superiores. Dos 30 marcadores ISSR testados, oito foram selecionados gerando um total de 102 locos, sendo 100 polim?rficos. Entre os tr?s est?gios, os jovens apresentaram maior ?ndice de diversidade gen?tica de Nei (He = 0,37), j? o menor ?ndice foi observado nos adultos reprodutivos (He = 0,34). Os resultados da AMOVA mostraram maior diferencia??o gen?tica dentro dos est?gios de desenvolvimento (98,61%) do que entre os est?gios (1,39%). A popula??o total apresentou rela??o positiva e significativa de parentesco na primeira classe de dist?ncia (12,3 m). Os jovens apresentaram parentesco significativo at? 10,5 m e negativa na quinta classe de dist?ncia (37,6 m). Os adultos n?o reprodutivos tiveram rela??o positiva de parentesco na primeira classe de dist?ncia (10,9 m) e distribui??o aleat?ria dos gen?tipos nas demais classes. Os adultos reprodutivos apresentaram gen?tipos espacialmente aleat?rios. Os valores para os testes de gargalo gen?tico demonstraram que o n?mero de locos com excesso de heterozigosidade observado foi maior que o esperado. Os resultados da EGE refletem a dispers?o restrita da esp?cie e os testes de gargalo a redu??o de gen?tipos provocados pela antropiza??o dos ambientes naturais de C. prunifera.
The present study aimed to develop microsatellite markers (SSR) for Copernicia prunifera; and characterize the demographic pattern and the spatial genetic structure (SGS) in different development stages of C. prunifera in a natural population of Rio Grande do Norte (RN) by using ISSR molecular markers. 17 SSR primers pairs were developed, which were tested by using DNA from samples of different populations. The demographic and genetic spatial structure was assessed in a plot with an area of 0.55 ha, where all individuals were georeferenced. The molecular analyses with the use of microsatellite markers pointed out that all built primers pairs, when submitted to PCR, had amplification. They showed sizes of base pairs ranging between 113 and 250 bp. The demographic analyses showed a clustered standard of spatial distribution in the first distance classes, random between 40 and 50 m and segregated in higher distances. Eight ISSR primers were used, thereby producing a total of 102 loci, with 100 of them being polymorphic. Among the three stages, the young showed the highest Nei?s genetic diversity index (He = 0.37); whilst the lowest index was found in the reproductive adults (He = 0.34). The AMOVA results showed a greater genetic differentiation within the development stages (98.61%) in comparison to the interval among the stages (1.39%). The total population (n = 161) showed a positive and significant relationship of kinship in the first distance class (12.3 m). The young showed a significant kinship up to 10.5 m and negative in the fifth distance class (37.6 m). The non-reproductive adults had a positive relationship of kinship in the first distance class (11.0 m) and random distribution of genotypes in the remaining classes. The reproductive adults showed genotypes spatially distributed in a random way. The values for the genetic bottleneck tests proved that the number of loci with excess observed heterozygosity was greater than expected. The SGS results reflect the restricted dispersion of the species, and the bottleneck tests reflect the reduction genotypes provoked by the anthropization of natural environments of C. prunifera.

Повний текст джерелаAccording to the traditional interpretation, the Copernican revolution devalued man by removing his central position in the cosmos and relegating him to a planet analogous to the others occupying an indistinct position in the universe. Presupposing that the centre of the world was always the most prestigious place, this interpretation thus identifies geocentrism with anthropocentrism and heliocentrism with anthropoperipheralism. But if the centre of the world has indeed been perceived favourably by heliocentrism, it has on the other hand been devalued by geocentrism as being low rather than central and dishonouring rather than glorious. Within this geocentric system, the dignity of man resides, thus, less in the centrality of his location than in the verticality of his body. The traditional interpretation was erroneous in its comprehension of geocentrism, but also as regards the anthropological consequences of the Copernican revolution. Heliocentrism does not lead to a simple devaluation of man, since the position and the characteristics of his planet may appear striking

Повний текст джерелаConcurrent Design Platform 4 (CDP4®) är ett samarbetsverktyg för modellbaserad systemteknik (MBSE) som utformats för att bygga komplexa system. Dock finns det begränsningar vad gäller det antalet hanterbara systemalternativ. Det kommande Siemens-verktyget för generativ teknik, Simcenter™ Studio, försöker övervinna denna begränsning genom att möjliggöra automatisk syntes och utvärdering av arkitekturvarianter. Motivationen för Generative Concurrent Design (GCD) -projektet som ett samarbete mellan RHEA, Siemens och OHB är att utveckla en kombinerad prototyp av verktygen CDP4® och Simcenter™. Detta examensarbete presenterar en modellering av rymdkomponenten Copernicus Next Generation (CNG) med användning av generativa funktioner i en typisk fas-0-studie. Den representerar det tredje steget i GCD-valideringsprocessen nedifrån och upp, avsedd att undersöka hur arkitekturen skiljer sig åt mellan "Sub-system", "Systems" och "Systems of Systems (SoS)". Detta arbete ger därför en arkitektonisk strategi som är generaliserbar för andra SoS-användningsfall och bidrar till att bedöma om förlängningar till ECSS-E-TM-10-25 är nödvändiga för att framgångsrikt stödja GCD.

Galileo Galilei supported Nicolaus Copernicus astronomic theory, from which the former has attracted philosophical as well theological consequences. The celestial discoveries made possible with the usage of spyglasses allowed Galileo to challenge some of the aristotelic principles of cosmology and to break up the limits imposed to astronomy as hypothetical discipline which would aim just to "save the phenomena".
Galileu Galilei defendeu a teoria astronômica de Nicolau Copérnico, e dela extraiu consequências filosóficas e teológicas. As descobertas celestes com a utilização da luneta permitiram a Galileu questionar alguns princípios da cosmologia aristotélica, e romper os limites impostos à Astronomia, enquanto disciplina hipotética que teria como objetivo tão somente "salvar os fenômenos".

Leaf extraction and the invasion of an exotic plant are two factors that may affect nutrient stock in the ecosystem of carnauba palm (Copernicia prunifera (Mill.) H.E. Moore). However, currently there isn´t any research that quantify the magnitude of these impacts. This work aimed to assess whether the extractive activity and the invasion of Cryptostegia grandiflora Roxb. ex R. Br., modify soil nutrient stocks in the carnauba ecosystem. Thus, the age of 90 plants was estimated. Foliar and soil analyses were performed, inside and outside tree canopy to determine soil stocks and the extraction of nutrients during leaf removal. The results indicate that leaf removal does not reduce the soil nutrient stock as well as the presence of an exotic plant does not increase soil carbon. In this sense, both impacts are not intensive enough to modify soil nutrient stocks, leastwise in the period considered for this study.
A retirada das folhas durante a atividade extrativista e a invasão de uma planta exótica, são dois impactos que podem afetar os estoques de nutrientes no ecossistema das palmeiras carnaúba (Copernicia prunifera (Mill.) H.E. Moore). No entanto, atualmente não existem pesquisas que quantifiquem a magnitude dessas duas perturbações nos carnaubais nativos. O presente estudo tem como objetivo avaliar se a atividade extrativista e a invasão de Cryptostegia grandiflora Roxb. ex R. Br., provocam variações nos estoques de nutrientes do solo no ecossistema da carnaúba. Assim, foram estimadas as idades de 90 carnaúbas, as quais foram submetidas à analise foliar e de solo, dentro e fora da projeção da copa das palmeiras, para determinar os estoques no solo e as exportações de nutrientes pela colheita das folhas. Pelos resultados observa-se que a atividade extrativista não diminui o estoque de nutrientes no solo, assim como a presença da invasora não incrementa os níveis de carbono. Nesse sentido, ambos impactos não apresentam intensidade suficiente para modificar os estoques de nutrientes do solo, ao menos na escala de tempo adotada neste estudo.

Altas concentraÃÃes de sais no solo tÃm sido um dos fatores que mais tÃm concorrido para a reduÃÃo do crescimento e produtividade das culturas.

O experimento constou de um arranjo fatorial 5x1. O ensaio dispÃs de 15 mudas com 4 repetiÃÃes, sendo adotado o mÃtodo de delineamento casualizado.

Actually, several regions of earth face serious soil problems because of salinisation. A major part of these cases occurs in regions with an accentuated water deficiency and shallow soils. The damage caused by salinity may become even more critical by inadequate handling and insufficient draining. High soil salt concentration has been one of the factors with major influence on reduced growth rates and productivity in cultivated plants. The Carnauba (Copernicia prunifera (Miller) H.E.Moore) is able to produce under conditions of low precipitation and is an option for income of great importance for the population of the Brazilian semi-arid regions. In our study, we tried to assess the effect of salinity on growth and initial development of Carnauba plantlets destined at supporting restoration of areas of permanent conservation (APPs) that were deforested or suffer from salinisation as well as to promote extractivism as a source of income in this region. In the experiment, we applied a 5x1 factorial arrangement. The assay made use of 4 repetitions with 15 plantlets each in a random distribution. Salinities of 0, 25. 50, 75 and 100 mol.m-Â NaCl, corresponding to conductivities of 2.0, 4.6, 7.1, 9.6 and 12 dS.m-1, respectively, were evaluated in relation to the indexes of initial growth of Carnauba plantlets. The following variables were studied: leaf length (Cra); leaf width (Lra); root length (CRp), fresh weight (PMF); dry weight (PMS); aerial part â root ratio (PAR) and survival rate (TS). Salinity differentially affected each variable studied, with TS suffering a major impact. As to the salinities applied, plantlets demonstrated best results at 25 and 50 mol.m-Â NaCl, better even at 25 mol.m-Â; here, the development of leaf width was best. Elevated salinities of 100 mol.m-Â or higher put at risk development and possibly survival of this plant, that thus turns out to be a glycophyte;production and/or replanting are not recommended for areas with these levels of soil salinity.

Nativa do Brasil, a Carna?ba (Copernicia prunifera) tem sido utilizada para diversos fins, incluindo a produ??o de cera a partir de suas folhas, cujo processo gera uma quantidade consider?vel de res?duo, o qual se caracteriza como uma fibra rica em celulose e, portanto, com um potencial para uso como fonte de carbono para a produ??o de enzimas celulol?ticas e etanol. A estrutura qu?mica desse material apresenta a celulose ligada a componentes estruturalmente complexos, como a hemicelulose e a lignina, o que dificulta a produ??o das celulases por fungos filamentosos, bem como, a sua hidr?lise enzim?tica, sendo imprescind?vel a utiliza??o de um pr?-tratamento para a viabiliza??o desses processos. O presente estudo avaliou o efeito de diferentes pr?-tratamentos na palha de carna?ba para a produ??o de enzimas lignocelulol?ticas e para a hidr?lise enzim?tica com vistas ? produ??o de etanol celul?sico por meio dos conceitos de biorrefinaria e microdestilaria. Na primeira etapa deste trabalho, o res?duo da palha de carna?ba foi submetido aos pr?-tratamentos hidrot?rmico (HT), alcalino (AL), ?cido alcalino (AA) e per?xido de hidrog?nio alcalino (A-HP). Os res?duos pr?-tratados e n?o tratado foram caracterizados quimicamente conforme o protocolo da National Renewable Energy Laboratory (NREL) e, fisicamente, por meio das an?lises de Microscopia Eletr?nica de Varredura (MEV), Difra??o de Raio X (DRX) e Espectroscopia de Infravermelho Transformada de Fourier (FTIR). Uma parte de cada res?duo foi utilizada para produ??o de enzimas por meio de Fermenta??o em Estado S?lido (FES), utilizando o fungo Trichoderma reesei CCT-2768. As atividades FPAse, CMCase, ?-glicosidase e xilanase dos extratos foram estimadas e a produ??o posteriormente otimizada. A outra parte dos res?duos foi submetida ? Sacarifica??o e Simult?nea Fermenta??o (SSF) com enzimas comerciais, utilizando as leveduras Saccharomyces cerevisiae UFLA CA11, Saccharomyces cerevisiae CAT-1 e Kluyveromyces marxianus ATCC-36907. Os resultados dos pr?-tratamentos AL, AA e A-HP se destacaram em termos de remo??o de lignina, segundo as an?lises qu?mica e f?sica dos res?duos. Os estudos evidenciaram que o pr?-tratamento da palha da carna?ba com A-HP possui maior capacidade de indu??o da produ??o de enzimas lignocelulol?ticas ao se comparar com outros res?duos lignocelul?sicos, como coco, caju e cana-de-a??car, pr?-tratados pelo mesmo m?todo. A otimiza??o da produ??o de enzimas lignocelulol?ticas permitiu a produ??o de um extrato enzim?tico com atividade FPase de 2,4 U/g e xilanases de 172 U/g. A aplica??o do extrato enzim?tico na hidr?lise do baga?o de cana-de-a??car pr?-tratado mostrou efici?ncia de 86,96%. A hidr?lise enzim?tica, com enzimas comerciais, do res?duo da carna?ba submetido ao pr?-tratamento AL, apresentou a maior convers?o de a??cares (64,43%) e, ao ser submetido ? SSF, produziu 7,53 g/L de etanol, usando Kluyveromyces marxianus ATCC-36907 cultivada a 45 ?C. Os resultados evidenciam, portanto, o potencial biotecnol?gico do res?duo da carna?ba para a produ??o de enzimas celulol?ticas e na obten??o de bioetanol em um arranjo de biorrefinaria e microdestilaria.
Native to Brazil, Carnauba (Copernicia prunifera) has been used for several purposes, including the wax production from its leaves, in the process that generates a considerable amount of residue. This residue is characterized as a fiber rich in cellulose and therefore with potential latent for use as a source of carbon for the production of cellulolytic enzymes and bioethanol. However, the chemical structure of this material presents cellulose bound to structurally complex components, such as hemicellulose and lignin, which hinders the production of cellulases by filamentous fungi, as well as its enzymatic hydrolysis, being essential to use of a pre-treatment for the viability of these processes. The present study evaluated the effect of different pre-treatments on carnauba straw for the production of lignocellulolytic enzymes and for the enzymatic hydrolysis with a view to the production of cellulosic ethanol through the concepts of biorefinery and micro-distillery. In the first stage, carnauba straw residue was submitted to hydrothermal (HT), alkaline (AL), alkaline acid (AA) and alkaline hydrogen peroxide (A-HP) pre-treatments. The pretreated and untreated residues were chemically characterized according to the National Renewable Energy Laboratory (NREL) protocol and, physically, by Scanning Electron Microscopy (MEV), X-Ray Diffraction (XRD) and Spectroscopy of Infrared by Fourier Transform (FTIR). A part of each residue was used to produce enzymes by means of Solid State Fermentation (FES), using the fungus Trichoderma reesei CCT-2768. The FPAse, CMCase, ?-glycosidase and xylanase activities of the extracts were estimated and the production was subsequently optimized. The other part of the residues was subjected to Saccharification and Simultaneous Fermentation (SSF) using commercial enzymes and Saccharomyces cerevisiae UFLA CA11, Saccharomyces cerevisiae CAT-1 and Kluyveromyces marxianus ATCC-36907. The results of the pretreatments AL, AA and A-HP stood out in terms of the removal of lignin, according to the chemical and physical analysis of the residues. The studies showed that pretreatment of carnauba straw with A-HP has a higher capacity to induce the production of lignocellulolytic enzymes when compared to other residues, such as coconut, cashew apple and sugar cane, pretreated by the same method. The optimization of the production of lignocellulolytic enzymes allowed the production of an enzymatic extract with FPase activity of 2.4 U/g and xylanases of 172 U/g. The application of the enzymatic extract in the hydrolysis of pretreated sugarcane bagasse showed efficiency of 86.96%. The use of AL pretreated carnauba residue in enzymatic hydrolysis, with commercial enzymes, showed a higher conversion of sugars (64.43%) and, when submitted to SSF, produced 7.53 g/L of ethanol, using Kluyveromyces marxianus ATCC-36907 cultured at 45 ?C. The results showed, therefore, the biotechnological potential of the carnauba residue for the production of cellulolytic enzymes and the production of bioethanol by means of biorefinery and micro distillery.

The use of raw materials from renewable sources for production of materials has been the subject of several studies and researches, because of its potential to substitute petrochemical-based materials. The addition of natural fibers to polymers represents an alternative in the partial or total replacement of glass fibers in composites. In this work, carnauba leaf fibers were used in the production of biodegradable composites with polyhydroxybutyrate (PHB) matrix. To improve the interfacial properties fiber / matrix were studied four chemical treatments to the fibers..The effect of the different chemical treatments on the morphological, physical, chemical and mechanical properties of the fibers and composites were investigated by scanning electron microscopy (SEM), infrared spectroscopy, X-ray diffraction, tensile and flexural tests, dynamic mechanical analysis (DMA), thermogravimetry (TGA) and diferential scanning calorimetry (DSC). The results of tensile tests indicated an increase in tensile strength of the composites after the chemical treatment of the fibers, with best results for the hydrogen peroxide treated fibers, even though the tensile strength of fibers was slightly reduced. This suggests a better interaction fiber/matrix which was also observed by SEM fractographs. The glass transition temperature (Tg) was reduced for all composites compared to the pure polymer which can be attributed to the absorption of solvents, moisture and other low molecular weight molecules by the fibers
O uso de mat?rias-primas de fontes renov?veis para a produ??o de materiais vem sendo objeto de diversos estudos e pesquisas, devido ao seu potencial na substitui??o de derivados petroqu?micos. A adi??o de fibras vegetais a pol?meros representa uma alternativa na substitui??o parcial ou total de fibras de vidro em comp?sitos. Neste trabalho, fibras da folha de carna?ba (Copernicia prun?fera) foram utilizadas na produ??o de comp?sitos biodegrad?veis com matriz de polihidroxibutirato (PHB). Para melhorar as propriedades interfaciais fibra/matriz foram estudados quatro tratamentos qu?micos, para as fibras. O efeito dos diferentes tratamentos qu?micos nas propriedades morfol?gicas, f?sicas, qu?micas e mec?nicas das fibras e dos comp?sitos foram investigados por microscopia eletr?nica de varredura (MEV), espectroscopia no infravermelho, difra??o de raios-X, ensaios mec?nicos de tra??o e flex?o, an?lise din?mico-mec?nica (DMA) e an?lises t?rmicas por termogravimetria (TG) e calorimetria explorat?ria diferencial (DSC). Os resultados dos ensaios de tra??o dos comp?sitos indicaram um acr?scimo de resist?ncia ? tra??o ap?s modifica??o qu?mica das fibras, sendo o melhor resultado obtido com o tratamento de per?xido de hidrog?nio, mesmo havendo uma pequena redu??o na resist?ncia ? tra??o das fibras tratadas. Isto indica uma melhor intera??o entre as fibras e a matriz polim?rica que foi tamb?m observada nas imagens de microscopia eletr?nica de varredura. A temperatura de transi??o v?trea (Tg) foi reduzida para todos os comp?sitos em rela??o ao pol?mero puro o que foi atribu?do a absor??o de solventes, umidade e outras mol?culas de baixo peso molecular pelas fibras

Copernicia prunifera (Arecaceae), popularmente conhecida como carna?ba, ? nativa da regi?o nordeste do Brasil, com ocorr?ncia ao longo das margens de rios e ?reas alagadi?as. Por ser vers?til em rela??o ?s formas de usos, essa palmeira ficou conhecida como ?rvore da vida , sendo o p? cer?fero o principal produto extra?do da C. prunifera. Este estudo teve como objetivos investigar aspectos etnoecol?gicos e etnobot?nicos da C. prunifera em uma comunidade extrativista, selecionar primers ISSR (Inter Simple Sequence Repeat) para estudos de gen?tica de popula??es, e estudar a diversidade e a estrutura gen?tica de uma popula??o natural no Estado do Rio Grande do Norte, Brasil. Foram entrevistados 11 moradores considerados informantes-chaves na regi?o de Ipangua?u/RN, onde 73% dos informantes relataram a ocorr?ncia de um morfotipo diferente de carna?ba, conhecida como carna?ba branca . Dos entrevistados, 82% afirmaram que a esp?cie possui dispers?o realizada por morcegos. Na etnobot?nica, o p? cer?fero foi citado por todos como o produto mais importante extra?do da C. prunifera e a folha a parte mais usada (45%), seguida dos frutos (29%), caule e raiz (ambas com 13%). Na sele??o de primers ISSR, dos 17 que foram testados, 12 amplificaram o DNA e, destes, sete foram selecionados para caracterizar a estrutura gen?tica de 37 indiv?duos remanescentes. O primer que obteve a maior porcentagem de locos polim?rficos (LP%) foi UBC 841 (16,36%), j? o primer que teve a menor LP% foi UBC 827 (8,18%). No estudo de diversidade e estrutura gen?tica dos indiv?duos de uma popula??o natural (regenerantes = 62, jovens = 20, adultos = 19) foram utilizados sete iniciadores ISSR que permitiram a visualiza??o de 93 locos, com 100% de polimorfismo. Os regenerantes foram os que mais se destacaram em rela??o ? diversidade gen?tica (He = 0,411 e Ho = 0,599), seguido pelos jovens (He = 0,394 e Ho = 0,579) e adultos (He = 0,267 e Ho = 0,427). A AMOVA mostrou que a maior varia??o gen?tica ocorre dentro dos est?gios de vida (93,42%) quando comparado entre eles (6,58%). O dendograma (UPGMA), com base na identidade gen?tica de Nei, mostrou maior semelhan?a genot?pica entre os jovens e regenerantes (0,979). No teste de hip?tese para o gargalo gen?tico (bottleneck) foi observado elevado n?mero de locos com excesso de heterozigosidade para os dois modelos utilizados (IAM = 92 e SMM = 91), indicando redu??o do tamanho efetivo populacional. Todos os est?gios de desenvolvimento apresentaram estrutura??o gen?tica espacial (EGE), com valores de coancestrias positivos e significativos, sendo os valores de Sp de 0,04 para os regenerantes, 0,093 para os jovens, 0,15 para os adultos e 0,53 para a popula??o geral. Essa EGE ocorre, provavelmente, devido ? dispers?o restrita de sementes

Nas ?ltimas d?cadas, a contamina??o dos corpos de ?gua por metais pesados vem se tornando um s?rio problema ambiental. O descarte inadequado de efluentes contaminados por ?ons de metais, mesmo em pequenas concentra??es, podem causar s?rios danos aos seres humanos, a fauna, flora e a microbiota, comprometendo assim, a qualidade de vida do ecossistema presente. Diante deste contexto, ? necess?rio o tratamento destes efluentes a n?veis ambientalmente aceit?veis antes de lan??-los no meio ambiente. N?o obstante a isso, o uso de bioadsorventes para o tratamento de efluentes contaminados, como alternativa a m?todos convencionais, tem sido objeto de estudo de diversas pesquisas contempor?neas. Nessa perpectiva, este trabalho buscou analisar a viabilidade da utiliza??o do p? das folhas in natura do cajueiro vermelho (Anacardium occidentale L.) e da carna?ba (Copernicia prunifera) como adsorventes para remo??o de ?ons de cobre presentes em efluentes sint?ticos. Inicialmente, foram investigadas as propriedades f?sico-qu?micas de ambas as folhas, utilizado ensaios de microscopia eletr?nica de varredura (MEV), difra??o de raio-X (DRX), fluoresc?ncia de raio-X (FRX), analise termogravim?trica (TG), espectroscopia na regi?o do infravermelho (FTIR) e adsor??o f?sica de nitrog?nio (BET). Os estudos de adsor??o foram realizados em sistema de batelada, cujo os efeitos do pH (3,0 a 10,0), da concentra??o do adsorvente (2 a 20 gL-1), do tamanho de part?cula (0,6 a 0,075mm) e da concentra??o inicial do adsorbato (10 a 150 mgL-1) foram avaliados. Os resultados indicaram um aumento na capacidade de adsor??o para valores de pH entre 3 e 7. Ap?s atingir pH igual a 7, observa-se que a capacidade de adsor??o ? reduzida, para ambos os estudos. Com rela??o a avalia??o da varia??o da concentra??o do adsorvente, observou-se que para o p? das folhas do cajueiro o aumento da quantidade de massa n?o afetou o processo de remo??o, no entanto, para o p? das folhas da carna?ba observou-se que o percentual de remo??o ? diretamente proporcional ao aumento da massa. Para ambos os casos estudados, observou-se uma melhor efici?ncia quando se utilizou part?culas com tamanhos compreendidos entre 0,106 e 0,075 mm. O estudo da concentra??o inicial para os bioadsorventes apresentaram comportamento semelhantes. A quantidade de adsor??o aumenta com o aumento na concentra??o inicial dos ?ons em solu??o. Os dados experimentais das isotermas de adsor??o realizadas no p? da folha de cajueiro melhor se ajustaram ao modelo de Freundlich, todavia, para o p? da folha da carna?ba o modelo de Langmuir mostrou-se mais adequado. A cin?tica do processo de adsor??o, para ambos os adsorventes, atingiu o equil?brio logo nos primeiros minutos de rea??o, aproximadamente, 2 minutos. De modo geral, os dados experimentais melhor ajustaram-se ao modelo de pseudo-primeira ordem para ambos os adsorventes. Comparando os adsorventes em estudo, observa-se que o p? da folha da carna?ba apresentou um desempenho superior de remo??o dos ?ons de cobre, atingindo um percentual de cerca de 79 %, onde nas mesmas condi??es de temperatura, concentra??o inicial, massa de adsorvente e volume da solu??o, o p? da folha do cajueiro removeu cerca de 19 %. Os resultados mostraram que o p? das folhas do cajueiro e da carna?ba apresentam caracter?sticas apropriadas para o processo de adsor??o do cobre e que podem ser uma alternativa a processos cl?ssicos de tratamento de efluentes.
Lately, the contamination of water bodies caused by heavy metals has become a serious environmental issue. The discharge of effluents which contain heavy metal ions, even at small concentration, without an adequate treatment damages human beings, fauna, and flora thus this affects the wellness of the entire ecosystem. Therefore, these effluents require certain treatment to lower the ions level to an environmentally acceptable concentration before discharging them into the environment. Additionally, bioadsorbents have been used for the treatment of contaminated effluents as an alternative to conventional methods. They have also been largely studied in recent researches. Hence, this work aims to evaluate the usage of red cashew (anacardium occidentale L) leaves and carna?ba (copernicia prunifera) leaves, in powder form, as adsorbents for copper ions removal from synthetic effluents. The physicochemical properties of both leaves were investigated, using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray fluorescence (FRX), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR) and physical nitrogen adsorption (BET).The adsorption studies were carried out in a batch system, whose effects of pH (3.0 to 10.0), adsorbent concentration (2 to 20 gL-1), particle size (0.6 to 0.075 mm) And the initial concentration of the adsorbate (10 to 150 mgL-1) were evaluated. The results indicated an increase in adsorption capacity at pH values between 3 and 7. After reaching pH equal to 7, it is observed that the adsorption capacity is reduced for both studies. Regarding the evaluation of the variation of the adsorbent concentration, it was observed that for the powder of the cashew leaves the increase of the mass quantity did not affect the removal process, however, for the powder of the leaves of the carnauba it was observed that the Percentage of removal is directly proportional to the mass increase. For both cases studied, a better efficiency was observed when using particles with sizes between 0.106 and 0.075 mm. The initial concentration study for the bioadhesives presented similar behavior. The amount of adsorption increases with the increase in the initial concentration of the ions in solution. The experimental data of the adsorption isotherms performed on the cashew leaf powder best fit the Freundlich model, however, for the carnauba leaf powder the Langmuir model was more adequate. The kinetics of the adsorption process for both adsorbents reached equilibrium in the first few minutes of reaction, approximately, 2 minutes. In general, the experimental data better fit the pseudo-first order model for both adsorbents. Comparing the adsorbents performance, it was observed that the carnauba leaves powder removed a superior copper ion amount, reaching a removal percentage approximately equal to 79 %, whereas, under the same conditions of temperature, initial concentration, adsorbent mass and solution volume, the cashew leaves powder showed a removal percentage approximately equal to 19 %. The results showed that both the cashew and carnauba leaves powder present the appropriate features for copper adsorption and they both represent an alternative to traditional effluent treatment processes.
