Millàs, i. Castellví Carles. "Aproximació a l’estudi de les migracions històriques a escala municipal: Olesa de Montserrat, 1581-1930." Doctoral thesis, Universitat Autònoma de Barcelona, 2015. http://hdl.handle.net/10803/321359.
Full textLa presente tesis doctoral es una monografía en demografía histórica en torno a los movimientos migratorios a nivel municipal y que abarca un espacio temporal de tres siglos y medio. Este marco cronológico se ha analizado, tanto diacrónica como sincrónicamente, mediante el vaciado nominativo de los hombres y las mujeres que han vivido en Olesa —un vaciado de más de 100.000 personajes descubriendo, así, 12.589 emigrantes y 13.510 inmigrantes—. Los seguimientos nominativos han permitido observar la reconstrucción de historias migratorias resiguiendo la trayectoria de vida de las persones con nombres y apellidos para acercarnos al fenómeno migratorio y a las características de esta gente y conseguir, con ello, descubrir, a través del conjunto de biografías y trayectorias de personas, su vida colectiva. Es a partir de estas trayectorias y biografías que hemos podido, por un lado, comprobar la capacidad de esta gente para desplazarse de un lado a otro, de cambiar de actividad económica o de estado civil y, por otro lado, es desde este pluralismo biográfico donde se mezclan realidades heterogéneas —diferentes tipos de familias, formas diversas de convivencia...—. La investigación se ha hecho con la intención, por un lado, de señalar, de la manera mas precisa posible y partiendo de unos fundamentos demográficos, los cambios y las continuidades de la movilidad de la población olesana en el paso del antiguo régimen demográfico al nuevo régimen demográfico; por otro lado, observar el inicio del desarrollo y los determinantes del paso de la sociedad agraria a la sociedad industrial y analizar las migraciones como uno de los fenómenos clave del proceso de industrialización y modernización. Muchos estudios sobre la movilidad de la población han empleado la ecuación compensatoria para calcular los saldos migratorios, generalmente con los stocks, pero el vaciado nominativo ha permitido verificar, después de corregir y depurar la información, los resultados. Se han constatado cambios con el paso de los años y, también, se ha puesto de manifiesto que Olesa pasa de ser una población receptora de inmigrantes a ser una población emisora de emigrantes para convertirse, nuevamente, en una población receptora de inmigrantes. La movilidad de la población ha influido en la dinámica y la estructura demográfica ya que se trata de una movilidad de corta y mediana distancia con predominio masculino y, generalmente, individual y cualificado, desde sus orígenes hasta bien entrado en el siglo XIX, y de una migración mayoritariamente femenina, y generalmente, en familia y poco cualificada, desde mediados del siglo XIX hasta 1930. Por otro lado, esta movilidad de corta distancia, al menos hasta mediados del siglo XIX, es fruto de los intercambios matrimoniales y de la circulación de mano de obra. En cambio, desde la segunda mitad del siglo XIX, a raíz de la industrialización y favorecida, poco después, por la filoxera hay un cambio radical extendiéndose la atracción hacia una población de otras regiones peninsulares, llegada, mayoritariamente, en familia. Estos migrantes, normalmente, siguen unos itinerarios: del campo y la montaña, incluso desde más allá de los Pirineos o de la Depresión del Ebro, hacia el litoral, pasando por Olesa, donde permanecerán temporal o definitivamente; o des de la Catalunya Nova, o mas al sur, y de mar adentro, hacia las cercanías de Barcelona donde llegarán a Olesa para quedarse temporal o definitivamente. Concretamente, en el traspaso del siglo XIX al siglo XX los itinerarios recorridos les llevan, general y previamente, por otros municipios industrializados como Terrassa, Sabadell, Manresa... poniendo de manifiesto una interacción entre el proceso de industrialización, la alfabetización y las migraciones.
This thesis is a monograph about the historical demography migration municipal level and covering a temporary space of three and a half centuries. This chronological framework has been analyzed, both diachronically and synchronously by emptying nominative men and women who have lived in Olesa —a dump more than 100.000 people discovering thus 12.589 13.510 emigrants and immigrants—. The monitoring allowed nominal grasp the reconstruction of stories along the migratory path of life of people with names to approach the migration and distinctive features of these people learn and achieve, through joint and biographies their collective life trajectories of individuals. It is from these trajectories and biographies that we have on the one hand, the ability to verify that people move from one place to another, changing economic activity or status and, moreover, it is from this pluralism biographical mingling heterogeneous realities —was different family types, different ways of living ...—. The research was done with the intention, first, be noted, as accurate as possible and based on a foundation of demographic changes and continuities of population mobility olesana in the transition from old demographic regime to the new regime; moreover, observed the beginning of the development and determinants step agrarian society to industrial society and analyzing migration as one of the key events in the process of industrialization and modernization. Many studies of population mobility have used the equation to calculate compensatory balances migration, often with stocks, but emptying nominative allowed to verify, after correcting the information and debug the results. Changes have been recorded over the years and also has shown that Olesa happens to be a host population of immigrants to be a broadcaster immigrant population to become once again a host population immigrants. The mobility of the population has influenced the dynamic demographic structure since it is a short and medium-distance mobility predominantly male, and generally qualified individual, from its origins until well into the nineteenth century, and a migration mostly female and often unskilled and family since the mid-nineteenth century to 1930. Moreover, this mobility short, at least until mid-nineteenth century, is the result of exchanges and marriage movement of labor. However, since the second half of the nineteenth century, following industrialization and favored soon after the fil·loxera there is a radical change extending an attraction towards people from other regions peninsular arrival, mostly in family. These migrants usually follow itineraries: the countryside and the mountains, even from beyond the Pyrenees or the Depression of the Ebro to the coast, passing Olesa, which will remain temporarily or permanently; or from the New Catalonia, or further south and offshore, to arrive on the outskirts of Barcelona Olesa to stay temporarily or permanently. Specifically, the transfer from the nineteenth to the twentieth century the routes followed are run often and previously by other industrialized towns like Terrassa, Sabadell, Manresa ... showing an interaction between the process of industrialization, literacy and migration.

Full textA técnica de eletrofloculação foi utilizada empregando-se eletrodos de alumínio para separar o óleo da água oleosa sintética contendo uma concentração média de 200 ppm de óleo cru. Para avaliar a sua viabilidade, foram determinados os percentuais de remoção de demanda química de oxigênio (DQO) e óleos e graxas totais (TOG), a concentração de sólidos totais, voláteis e fixos, a condutividade elétrica, o pH, a acidez e a alcalinidade total das amostras do efluente oleoso ao longo do tratamento. Estimou-se, também, o custo energético e operacional para o desenvolvimento da técnica. Neste trabalho construiu-se um reator eletrolítico, de bancada, com capacidade de 4 litros. Em seu interior, eletrodos de alumínio em arranjo paralelo foram conectados a uma placa alternadora de polaridade e a uma fonte de corrente contínua. Testes preliminares foram realizados para definir a melhor relação área do eletrodo por volume de efluente quanto à remoção de DQO. A partir destes testes, fixou-se o maior eletrodo (13,0 X 6,5 X 0,2 cm) por ter apresentado a melhor condição (cerca de 90%). Nos resultados foram verificados: aumento do pH; a condutividade elétrica e a concentração de sólidos apresentaram valores próximos durante o tratamento; a média percentual de remoção de TOG foi de 96%, enquanto que a de DQO foi de 81%. No fim da eletrólise, o efluente resultante ficou qualitativamente transparente. A análise estatística para condutividade elétrica e concentração de sólidos totais mostrou que estas dependem significativamente da concentração de eletrólito no meio (NaCl). Para a DQO e o TOG, somente a distância entre os eletrodos foi o fator significativo. Já a variação de pH inicial não apresentou significância em relação as variáveis analisadas. Quanto ao custo energético, a técnica de eletrofloculação apresentou, em média R$ 0,32/m3, um consumo do eletrodo de 0,60 g.e um custo operacional R$ 3,41/m3. Frente aos resultados, constatou-se que é possível utilizar a técnica de eletrofloculação no tratamento de água oleosa devido aos valores técnico-econômico satisfatórios, comparados com a literatura.

O presente estudo objetivou otimizar a produção de biossurfactantes por diferentes culturas bacterianas, em diferentes meios de cultura e com diferentes fontes de carbono, para aplicação no tratamento da borra oleosa sedimentada nos tanques de armazenamento de óleo combustível da RECAP (SP), pertencentes à Petróleo Brasileiro S/A (). Trinta e seis isolados, sendo 15 pertencentes ao Laboratório de Biodiversidade e Biotecnologia para o Meio Ambiente (BBMA) e 21 isolados da amostra de borra, foram avaliados quanto à produção de biossurfactantes. Dentre os 15 isolados com essa característica, foram selecionados cinco para a realização dos ensaios de otimização da produção de biossurfactantes. Os isolados foram identificados pela análise de ésteres metílicos de ácidos graxos (FAME) utilizando o sistema Sherlock da Microbial Identification System (MIDI, Newark, DE, EUA) como Pseudomonas aeruginosa (88A), Bacillus subtilis (155) e Arthrobacter sp. (201). Os isolados 111A e 191 não foram reconhecidos pelo sistema Sherlock. A concentração micelar crítica (CMC) dos biossurfactantes nos meios de cultura, após a remoção das células, foi estimada por quantificação da tensão superficial pelo método de du Nouy. A diluição micelar crítica ficou entre 0,01% e 1% do meio, indicando que as concentrações dos biossurfactantes nos meios estavam de 100 a 10.000 vezes acima de suas CMCs. A estabilidade das emulsões água- querosene, na presença dos biossurfactantes, variou de 30 a 70% após 42 horas, enquanto a estabilidade da emulsão formada pela mistura do surfactante sintético SDS e querosene foi de 45%. A produção de biossurfactantes variou significativamente com a composição do meio de cultura. A borra oleosa foi um indutor efetivo da produção de biossurfactantes. Os biossurfactantes produzidos na fase anterior foram utilizados para tratar a borra oleosa, visando a separação do óleo e do material inerte. O processo mostrou-se altamente eficiente em recuperar o óleo retido, chegando-se a 95% de redução do volume da borra. Os resultados mostraram que a utilização de biossurfactantes para o tratamento de borras oleosas pode ser uma tecnologia econômica e ambientalmente viável, considerando o pequeno volume de cultura microbiana requerido para o tratamento.
This work aimed at optimizing the production of biosurfactants by bacterial cultures for the treatment of oily sludge from fuel oil storage tanks at Capuava Refinery (RECAP-SP), Petróleo Brasileiro S.A. (PETROBRAS). Fifteen strains of the belonging to the collection of Laboratório de Biodiversidade e Biotecnologia para o Meio Ambiente (BBMA) and 21 strains isolated from oily sludge samples were evaluated for biosurfactant production. Among the biosurfactant producing isolates, five were chosen for the optimization of biosurfactant production. The isolates were identified as Pseudomonas aeruginosa (88A), Bacillus subtilis (155), and Arthrobacter sp. (201). The isolates 111A and 191 could not be identified. The critical micelar concentration (CMC) of biosurfactants in the culture media after cell removal was estimated by measuring surface tension of diluted samples by the du Nouy method. The critical micelar dilution ranged from 0.01% to 1%, indicating that the biosurfactant concentration in the medium was 100 to 10.000 times higher than its CMC. The stability of water-querosene emulsions in the presence of biosurfactants ranged from 30% to 70% after 42 hours, while the stability of the mixture of the synthetic surfactant SDS with kerosene was 45%. The xcomposition of the culture medium significantly affected the production of biosurfactants. The oily sludge was an effective inducer of biosurfactant production. The biosurfactants produced by the five isolates were used for oily sludge treatment, aiming at the separation of oil from inert materials. The process was highly efficient, resulting in 95% reduction of the oily sludge volume. The results showed that the use of biosurfactants for oily sludge cleanup operations can be an economically and environmentally attractive technology.

Full textDuring the process of petroleum refining an oily sludge residue is generated comprising about 0,34% of the total volume processed. Among the possible treatments for oily sludge are physical, chemical and biological. The landfarming is a technique in which the oily residue is incorporated into the soil under controlled conditions to promote degradation and immobilization of hazardous contaminants present by soil microorganisms. The aim of this study was to evaluate bioremediation strategies such as bioaugmentation and biostimulation in landfarming soil contaminated with oily sludge. We collected soil samples from cell landfarming and oily sludge from Sicecors in the Triunfo Petrochemical Plant Complex. Four bacteria previously isolated by Cerqueira (2011) from landfarming soil and oily sludge were used to form a microbial consortium for the bioaugmentation strategy and three C: N: P ratios (dose 1: 100:0,5:0,125; dose 2: 100:6:1,5 and dose 3: 100:12:3) were selected for biostimulation treatments. The bioaugmentation treatment and biostimulation (named respectively as AD1, AD2, AD3, ED1, ED2 and ED3) were used alone and also in combined (named as AED1, AED2 and AED3). The indicators were: production of CO2-C, P mineral, N mineral, hydrolysis of fluorescein diacetate (FDA), pH and total petroleum hydrocarbons (TPH). The greater release of CO2-C occurred in treatments containing dose 2 of fertilizer, and greater still when the consortium was added. Inorganic forms of nitrogen and phosphorus varied between treatments, the highest values being observed at higher doses of fertilizer added. It was observed that the greater hydrolytic activity over FDA was observed in treatment AED1. When the dose of fertilizer was increased in bioaugmentation, the hydrolytic activity decreased. Regarding the values of TPH, treatment AED1 showed the highest value. In the treatments AED1, AED2 and AED3 TPH values were inversely proportional to the doses applied, and for the treatments ED1, ED2 and ED3 TPH values were not affected by increasing doses. The results allow us to conclude that fertilization associated with microorganisms can be a good strategy for degradation of oily sludge in soil.

Full textRefineries and petrochemical industries inevitably generate considerable volumes of oily sludge during processing. Due to the complex composition of hydrocarbons, this sludge must be considered as a residue toxic, mutagenic and carcinogenic. Bioremediation technologies for the treatment of this important environmental contaminant show to be promising and politically, economically and socially attractive. The goal of this study was to isolate, identify and select bacteria with potential for biodegradation of oily sludge and evaluate its ability for biodegradation of petrochemical residues in soils with and without a historic contamination. We studied the efficiency of bioremediation in impacted soils containing different levels of contamination with an open and closed systems. Forty-five bacteria strains were isolated, 21 from soil Landfarming, 11 from petrochemical effluent and 13 directly from the oily sludge. Of these, five bacteria, identified based on partial sequencing of the 16S rRNA gene as Stenotrophomonas acidaminiphila BB5, Bacillus megaterium BB6, Bacillus cibi, Pseudomonas aeruginosa and Bacillus cereus BS20 were selected and used in the microbial consortium formulation Evaluation in mineral medium for 40 days with consortium selected showed degradation of oily sludge, reducing 90.7% and 51.8% aliphatic and aromatic fraction, respectively. Among the examined soils, the Landfaming showed greater potential in the treatment of oily sludge, reaching maximum of 74.9% and 74.3% in biostimulation and bioaugmentation respectively, after 90 days of the process. The evaluation of contaminated soils with 6% of oily sludge, monitored for 120 days in a closed system, exhibited promising rates of biodegradation with biostimulation (84.1%) and bioaugmentation (81.3%) strategies. The consortium selected was effective on bioremediation of oily sludge in a liquid medium and soil. The results indicated the potential of the bacterial consortium in the wastewater treatment system in order to reduce the pollutant load sent to the Landfarming area, thus, reducing environmental passives and increased efficiency from industrial processes.

Full textO aumento da poluição industrial tem levado os órgãos de controle ambiental a rever a legislação em vigor e a limitar de forma mais rigorosa o descarte de efluentes industriais. Em contrapartida, as empresas têm melhorado os sistemas de tratamento de seus efluentes, aplicando novas tecnologias. Na indústria de petróleo, na separação óleo-água, são usados flotadores e hidrociclones. A flotação procura recuperar o resíduo de óleo através de separação gravitacional, enquanto que os hidrociclones procuram acelerar este processo com o uso da força centrífuga. Os hidrociclones em estudo são equipamentos constituídos de uma parte cilíndrica e duas partes cônicas justapostas, nas quais a alimentação é constituída por duas entradas em voluta, diametralmente opostas, apresentando um eixo normal ao do equipamento e posicionada tangencialmente à parede lateral do cilindro. O separador tem duas aberturas para saída, posicionadas axialmente ao equipamento, uma delas, chamada overflow, situada próxima à seção de alimentação e a outra, chamada underflow, situada próxima ao vértice do corpo cônico do hidrociclone. A análise do comportamento fluidodinâmico do hidrociclone foi conduzida através da simulação numérica do tratamento da água produzida, aplicando-se métodos de Fluidodinâmica Computacional (CFD). Na ferramenta computacional utilizada, CFX, é possível construir a geometria, desenhar a malha numérica, ajustar os parâmetros de simulação, resolver e analisar os resultados, podendo ser aplicado para diversos tipos de escoamento. Realizou-se um planejamento experimental com o objetivo de analisar a influência da geometria na eficiência de separação do hidrociclone, ou seja, saber quais variáveis eram mais relevantes para a eficiência de separação. Para avaliar o desempenho do equipamento foram calculadas a Razão de Fluido (Rf) e a Eficiência Granulométrica Reduzida (G ), para cada geometria. Devido ao grande número de variáveis testadas, quais sejam Dc, Do, Du, Hc, VF e L1 optou-se por não analisar o efeito de cada uma em separado, mas a interações destas. As diferentes simulações numéricas foram consideradas como experimentos computacionais. Em todos os 19 experimentos computacionais, as simulações foram iniciadas com o modelo de turbulência k-, estas últimas utilizadas como valores iniciais para as simulações com o modelo de turbulência SSG, pois este último é o que melhor representa o escoamento no hidrociclone. As análises feitas no Essential Regression mostram que as variáveis que mais influenciam a eficiência de separação são os diâmetros de overflow e de underflow. As eficiências granulométricas reduzidas ficaram bem distribuídas na faixa 0-96%, o que mostra que a escolha do tamanho de gota testado (250 mm) foi adequada. Os maiores valores de razão de fluido foram obtidos para Do/Du @ 1,0 e os menores, excluindo-se Rf = 0, para Do/Du @ 0,2. Nos intervalos estudados, os maiores valores de Eficiência Granulométrica Reduzida são obtidos com os maiores valores de Do e os menores de Du. Os menores resultados de Razão de Fluido são obtidos com os menores valores de Do e os maiores valores de Du.

Full textThe olive « Olea europaea L. Ssp europaea» is an emblematic tree in Tunisia. Both wild (var. Sylvestris ) and cultivars (var. Europaea) forms ofthis tree are omnipresent since thousands ofyears. This olive germplasm is diversified but little is known about its origin. Ln order to study the genetic structure and to determine the origin of Tunisian olives, we performed molecular analysis of olive trees sam pied inTunisia (lOI accessions and 20 wild forms) and in Estern and Western Medeterranean (27 cultivars and 10 wild forms). The analysis of the lOI Tunisian olive accessions with RAPDs and SSRs revealed 75 RAPD phenotypes from which 25 were confirmed with SSR genotyping. The 50 remaining ones were c1assified into 17 SSR genotypes. These results showed that tunisian olive germplasm is diversified. Ln conclusion, 41 genotypes were determined and retained for the establishment of molecular reference data base that represent the sum of diversity and enable the construction of « core collection ». Genetic structure ofthese varieties in comparison with the other olive trees sam pied in this study was investigated with both RAPD and SSR data. Four statistical approaches (multivariate analysis (AFe), distance based hierarchical c1ustering, Bayesian inference and analysis of molecular variance (AMOY A)) were used. RAPD and SSR data were analysed in the same manner to determine correlation between these two nuclear approaches. Comparisons showed correlation in qualitative results but quantitative values differed according to the method of analysis. Based on nuclear SSR and RAPD data, two levels of structure were revealed: first: cultivars and oleasters were separated in two distinct groups; second, four less differentiated c1usters, corresponded to two groups of cultivars and two groups of oleasters, were detected. These results showed an East-West divergence of olive cultivars and revealed two wild forms in Tunisia: true oleasters and ferai forms. Based on nuclear and plastid data the origin ofTunisian olive varieties was investigated. Thus, varieties which displayed a chlorotype specific to the Eastern Mediterranean (CE 1 or CE2) and c1ustered with cultivars from the East are probably varieties introduced from the East. Yarieties grouped with oleasters and displayed a chlorotype of the Western Mediterranean (COMI, COM2 or CCK) are locally selected varieties. Ln this group, varieties with the Eastern Mediterranean chlorotype are probably the result of introgression between local genetic pool and introduced varieties. These results suggest different domestication events and a multiple and complex origin of Tunisian cultivars

Full textCon el fin de mejorar la regulación de la carga frutal en olivos bajo producción orgánica, se estableció un ensayo de poda, utilizando para ello árboles de 8 años de edad, de la variedad aceitera Coratina, en su año de alta producción. El ensayo se realizó en el fundo “El Oliveto” (33º48 latitud sur y 71º05 longitud oeste y 205 m.s.n.m. de altitud), localidad de Cholqui, comuna de Melipilla, provincia de Melipilla, Región Metropolitana, Chile. La poda se efectuó a fines de primavera, el 13 de diciembre del 2006. Se realizaron tres tratamientos, con cinco repeticiones (árboles) cada uno. El Tratamiento 1 fue el testigo sin poda; el Tratamiento 2, una poda del 33,3% de la madera productiva y el Tratamiento 3, una poda del 50% de la madera productiva. Se realizaron evaluaciones quincenales del crecimiento de brotes y de frutos. A cosecha se evaluó la relación pulpa carozo, porcentaje de pulpa, peso final, humedad y contenido de aceite de los frutos y parámetros productivos tales como, número de frutos, carga frutal, eficiencia productiva y producción por árbol. Ambos tratamientos de poda lograron reducir en forma muy significativa, la producción por árbol, eficiencia productiva y carga frutal. Con ambos tratamientos de poda se logró aumentar el largo total de los brotes en 100% y el número de nudos en aproximadamente un 40%, respecto del tratamiento testigo. El tratamiento de 50% de poda aumentó en 17% el peso por fruto. No hubo diferencias en el tamaño y humedad de los frutos, así como en el porcentaje de aceite al momento de la cosecha. El tratamiento que entregó resultados más óptimos fue el de 33,3% de poda, ya que, en la mayor parte de los parámetros medidos presentó resultados similares, estadísticamente, al tratamiento de 50% de poda, siendo su principal ventaja el haber presentado una menor reducción del rendimiento de la temporada en que se realizaron los tratamientos.

Full textIn plants, the structural dynamics and concerted evolution of nuclear and cytoplasmic genomes are poorly understood. The objective of this thesis was to study the structural diversity and evolution of mitogenomes and plastomes in the family Oleaceae with a phylogenomic approach. First, we assembled mitogenomes from low-coverage sequencing data obtained from live and herbarium material. Considerable structural variation of mitogenomes was observed in the olive, and a chimeric gene potentially associated to a type of male sterility was detected. Finally, we studied the evolution of plastomes and mitochondrial genes in the Oleaceae. Accelerated evolution of plastomes was observed in two independent lineages. This change of evolutionary rate could be the consequence of an occasional transmission of plastids with pollen, modifying selective pressures on some genes

A cepa bacteriana Pseudomonas aeruginosa LBI, isolada de solo contaminado com hidrocarbonetos, foi inoculada visando promover a degradação dos hidrocarbonetos através da capacidade de produção de biossurfactantes. Como matéria prima alternativa de baixo custo para produção biossurfactantes utilizou-se a borra oleosa proveniente do fundo de tanques de estocagem da REPLAN-PETROBRAS. Os ensaios foram realizados em triplicatas a 30C, 200 rpm, durante 168 horas e o acompanhamento foi realizado por amostra a cada 24 horas para quantificar o biossurfactantes e o crescimento celular. A tensão superficial, PH e os estudos de estabilidade e emulsificação foram realizados com o sobrenadante do cultivo de 168 horas. A cepa bacteriana mostrou-se capaz de se desenvolver e produzir biossurfactantes em querosene, óleo diesel, petróleo e borra oleosa. Apenas benzeno e tolueno não apresentam resultados positivos.
Pseudomonas aeruginosa LBI isolated from hydrocarbon contaminated soil and potential producer of biosurfactant was used for hydrocarbon biodegradation. The petroleum waste from REPLAN-PETROBRAS, alternative source of low cost to biosurfactante synthesis was utilized on medium culture. These studies were done at 30C with shaking at 200 rpm, during 168 hours, in triplicate. The samples were withdrawn daily for growth studies and biosurfactante production. The surface tension, PH and stability studies were done with the cell-free broth after 168 hours of incubation. The strain was able to produce biosurfactantes and to grow on the analyzed carbon sources, except benzene and toluene. When cultivated on diesel oil 30%, the strain produced higher quantities of biosurfactante. The biosurfactante was able to emulsifier all analyzed hidrocarbons. Stability studies of the product on the culture broth indicate that the biosurfactante is stable in extreme conditions. Therefore the strain Pseudomonas aeruginosas LBI and the biosurfactante produced have potential applications in bioremediation of site hydrocarbon contaminated, and possible application in enhanced oil recuperation.

Full textIn less than a decade since the onset of the global economic crisis, more than 2 million people have left Spain in search of work and the possibility of a livable existence. Many of these economic exiles are young and highly qualified, leading some to classify this exodus as a brain drain. Lingering labor market instability and growing mistrust in Spain’s political system portend a challenging future for members of the so-called “lost generation,” both at home and abroad. Meanwhile, many questions remain about the lasting effects and repercussions of the crisis and massive departure of young Spaniards.
In response, the recession and ensuing surge in emigration have been popular themes of economic, demographic and sociological research in recent years; however, the cultural productions representative of this group remain relatively unstudied. The current investigation focuses on a selection of documentary films and fictional literature that portray the experiences of these highly qualified migrants. Through close analysis of these works, narrative patterns and trends appeared. These literary and audiovisual texts manifest the dialectical tensions of exile literature theorized by Sophia McClennen as well as the complex nostalgias of Svetlana Boym. They also reject and redefine the generational terms imposed upon them, express diasporic solidarity and call for political involvement and collective action. The rhetorical undercurrents at work in these constructions of individual and group identity suggest the emergence of an archetypal narrative of the new Spanish migrant. The cultural negotiations implicit in this narrative seem to confirm that sweeping but gradual societal changes are taking effect, even beyond Spain's borders.

ABSTRACT Understanding of the interference promoted by species existing in weed community of olive groves and their densities are important considerations in management of these plants to maintain the competition balance, allowing the cultivation of olive trees be favored. The research was conducted with the aim of evaluate the competitive ability of olive nursery trees grown with different species and weed densities on vegetative growth and nutrients contents. Three experiments was conducted in a greenhouse of Setor de Fruticultura of Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), Diamantina, MG to evaluate the competition ability of olive tree with the weeds. The first experiment evaluated the nursery tree growth of two olive cultivars ?Arbequina? and ?Koroneiki? coexisting with five plant species: Bidens pilosa, Brachiaria brizantha, Cenchrus echinatus, Canavalia ensiformis and Lupinus albus and one treatment without coexistence for a period of 60 days. It was observed that the ?Arbequina? cultivar was more tolerant to interference of plant species. B. pilosa, C. ensiformes and L. albus were the species with greater potential for interference on the growth of olive nursery trees. In the second it was evaluated the growth of two olive cultivars, ?Arbequina? and ?Ascolano? planted with four species of competing plants, B. brizantha, A. retroflexus, B. pilosa and C. echinatus and the controls, which were the olive nursery trees and the weeds of each species without competition for a period of 90 days. Competition with weeds affected the growth and nutrients contents of olive nursery trees. ?Ascolano? was more tolerant to the competition with weed species. The species A. retroflexus and B. pilosa were the species with the greatest potential competition with olive nursery tree. In the third experiment was evaluated the relationship between the olive nursery trees ?Arbequina? and ?Ascolano? with four densities of B. brizantha zero, one, two, three and four plants per pot for a period of 70 days. It was observed that B. brizantha affected negatively in vegetative growth of olive nursery trees. The cultivar ?Ascolano? showed greater competitive ability with all densities of B. brizantha. The increased density of B. brizantha affected the nutritional status of olive nursery trees.

Full textThe objective of this study is applying the encapsulation technique, also known as solidification/stabilization, in soil contaminated with increasing amounts of acidic oily sludge industrial residues, using Portland cement CP-V ARI as the encapsulating agent. The experimental program consisted of studies pre and post-treatment, in which the soil was physically analyzed through geotechnical characterization testings, compactation, unconfined compressive strength, duration and hydraulic conductivity tests. In chemical terms, column leach testings were conducted, along with chemical and physical-chemical analyses of the leachete. Due to the high temperatures detected upon mixing soil/cement and the acidic oily sludge, tests were conducted to monitor the temperature and the hydratation rate of the cement. The results show that the greater the amount of acidic oily sludge in the treated soil, the higher the temperature necessary to hydrate the cement and the faster it reaches the maximum peak, which results in less unconfined compressive strength and greater mass loss. In samples without cement, the hydraulic conductivity reduced upon increasing the amount of acidic oily sludge. When cement is added, the hydraulic conductivity initially decreases with the acidic oily sludge, but it increases again with greater amounts of the substance. The encapsulation technique proved to be efficient in the reduction of heavy metals, due mainly to the pH increase and the precipitation of such components. However, the technique did not prove to be efficient in relation to sulphate, and to the electrical conductivity and the chemical oxygen demand.

Leishmaniasis is a disease transmitted by protozoans of the Leishmania gender. A huge number of species are responsible for the infection in human beings, resulting in three clinical phenotypes. The World Health Organization – WHO classify them as neglected diseases, and encourages the search of new medical drugs or formulations that are effective and that have low toxicity to humans. All the medical drugs actually used for the treatment of the leishmaniasis present some kind of restriction such as high toxicity, severe side effects, elevated cost, parenteral administration or teratogenicity. That being said, the development of more effective and selective drugs is very important, and the identification of exclusive metabolic pathways of the parasites that can be targeted might be an interesting starting point. Medicinal plants have been a rich source to the obtaining of molecules to be therapeutically explored. The Bixa Orellana L., popularly know as “annatto”, presents different pharmacological activities that are already proven. The objective of this work was to verify the anti-leishmaniasis potential and the toxicity of the phytochemicals of the oily fraction of Bixa Orellana and bixin extracted of its seeds, aiming to verify and prove its biological activity, security and therapeutic effectiveness in order to develop a phytotherapic drug. The bixin was characterized through a nuclear magnetic resonance spectrum of ¹H and ¹³C, and the oily fraction by a gas chromatography within a mass spectrometer. It can be inferred that the bixin and the oily fraction are presented as toxic because they have shown values of LD50 of 353,64±67,54 and 285,41±35,81μg/mL, respectively, and present low toxicity against swiss mouse erythrocytes and low toxicity after acute administration of the 2000 mg/mL doses. The bixin and the oily fraction inhibited the growth of promastigote forms, generating an IC50 of 2,16 μg/mL and 1,26 μg/mL, respectively, for the Leishmania major. The Trypan blue exclusion test has shown a significant cytotoxicity of the studied substances over murine macrophages. The calculated CC50 for the murine macrophages was 59,51 μg/mL and 111,41 μg/mL, for the bixin and oily fraction, respectively, so, they are more toxic for the parasites than for the relieved macrophages. The bixin and the oily fraction did not present an in vivo anti-Leishmaniasis effect in swiss mice infected with the L. major. It can be concluded that both bixin and oily fraction presented anti-Leishmaniasis activity (leishmaniostatic and leishmanicide) against promastigote forms of L. major.
A leishmaniose é uma doença transmitida por protozoários do gênero Leishmania. Numerosas espécies são responsáveis pela infecção em humanos, resultando em três fenótipos clínicos. A OMS as classificam como doenças negligenciadas, e incentiva a busca de novos fármacos ou formulações que sejam eficazes e que tenham baixa toxicidade ao homem. Todos os fármacos atualmente em uso para o tratamento da leishmaniose apresentam restrições, como toxicidade, graves efeitos colaterais, custo elevado, administração parenteral ou teratogenicidade. Desta forma, o desenvolvimento de fármacos mais eficazes e seletivos é de suma importância, e a identificação de vias metabólicas exclusivas do parasita que possam ser usadas como alvo pode ser um ponto de partida interessante. As plantas medicinais têm sido uma rica fonte para obtenção de moléculas para serem exploradas terapeuticamente. A Bixa orellana L. popularmente conhecido como “urucum” apresenta diversas atividades farmacológicas comprovadas. O objetivo do presente estudo foi verificar o potencial antileishmania e a toxicidade dos fitoconstituintes da fração oleosa da semente de B. orellana L. e da bixina, visando comprovar sua atividade biológica, seguranças e eficácia terapêutica. A bixina foi caracterizada através de espectros de ressonância magnética nuclear de ¹H e ¹³C e a fração oleosa por cromatógrafo a gás acoplado a espectrômetro de massas. Pode-se inferir que a bixina e a fração oleosa apresentam-se como tóxicos para Artemia salina por apresentar valor de DL50, respectivamente, de 353,64±67,54 e 285,41±35,81μg/mL, baixa toxicidade frente eritrócitos de camundongos suíços e baixa toxicidade após administração aguda na dose de 2000 mg/mL.A bixina e a fração oleosa inibiram o crescimento das formas promastigotas, gerando uma IC50 de 2,16 μg/mL e 1,26 μg/mL, respectivamente, para Leishmania major. O teste de exclusão do azul de Trypan demonstrou uma significativa citotoxicidade das substâncias em estudo sobre macrófagos murinos. A CC50 calculada para os macrófagos murinos foi de 59,51 μg/mL e 111,41 μg/mL, para a bixina e fração oleosa, respectivamente, portanto, são mais tóxicas para os parasitos que para os macrófagos avaliados. A bixina e a fração oleosa não apresentaram um efeito antileishmania in vivo em camundongos suíços infectados com L. major. Pode-se concluir que a bixina e a fração oleosa apresentaram atividade antileishmania (leishmaniostática e leishmanicida) sobre formas promastigotas de L.major.

Full textNesse trabalho foi desenvolvido um reator de eletrofloculação, cilíndrico, em regime contínuo no tratamento de água oleosa. Foi analisado o potencial de remoção de óleo emulsionado e o consumo de energia. A qualidade da emulsão foi determinada por meio da caracterização do efluente sintético quanto a sua estabilidade e distribuição do tamanho médio de gotas de óleo. Com o auxílio do software livre imageJ 1.40, foi possível determinar o tamanho médio das gotas. Como o reator funcionou continuamente, testes foram realizados para avaliar as condições de escoamento. Para isto, injetou-se o corante azul antes da entrada do reator para atuar como marcador. Verificou-se, qualitativamente, a crescente formação do vórtex quando o reator operava com vazões mais altas, sem a presença dos eletrodos. Quando os eletrodos côncavos eram colocados no interior do reator e posicionados próximos a entrada, essa concavidade contribuía para o movimento em espiral. Os dados experimentais foram realizados empregando-se a técnica do planejamento experimental elevando-se vazão, corrente elétrica e distância entre eletrodos. O interesse consiste em avaliar o percentual de redução do teor de óleos e graxas e o consumo energético visando a busca da melhor condição operacional. Em todos os experimentos, foram coletadas amostras para determinação do teor de óleos e graxas (TOG) e foram medidos o pH do meio. Também foram avaliados em todos os experimentos os desgastes dos eletrodos determinando-se as variações da massa dos eletrodos antes e após experimento considerando que a massa perdida converteu-se em concentração de Al3+ liberada para o meio reacional. No decorrer do processo de eletrofloculação foi possível estimar o consumo energético. A técnica do planejamento contribuiu para obtenção de um modelo linear simples tanto para o percentual de remoção de óleo (R2 = 0,9935) quanto para o consumo de energia (R2 = 0,9452). Pôde-se concluir que esse reator de eletrofloculação na melhor condição de operação avaliada apresentou um consumo de energia de 4,07 Wh/4L, alcançando 89% de eficiência de remoção de óleo que atende normas técnicas do CONAMA (N° 430, 2014).

Full textOliviculture is a recent activity in Rio Grande do Sul with few records on associated insects. In this study we aimed to inventory and identify the complex of scale insects and their parasitoids, describe the structure of communities and quantify parasitism in olive trees. The experiment was conducted in olive orchard, Olea europaea L., cultivar Arbequina, kept under traditional management, situated in Caçapava do Sul (30°33'29,79"S and 53º24'09,48"W), RS, Brazil. Samples were monthly collected from April 2012 to March 2013. At each occasion 20 trees were randomly selected and, from each quadrant of their canopies (northern, southern, eastern and western) three branches were removed, two randomly for the scale insects evaluation and one chosen to be heavily infested with Coccoidea for the parasitoids evaluation. The branches were between 20 and 30 cm in length and contained at least 20 leaves. At the laboratory scale insects of random branches were identified and counted, while the ones from the chosen branches were separated by species and stored in tubes that were in climate chamber (25 ± 1 ºC, 12 h photoperiod) for up to 60 days to observe the emergence of parasitoids, these dead and identified. It was found a scale insects complex comprising a Coccidae, Saissetia oleae, the most abundant and five Diaspididae, Aonidiella aurantii, Abgrallaspis cyanophylli, Acutaspis paulista, Aspidiotus nerii and Melanaspis sp. The microhymenopterans associated were Aphytis sp., Coccophagus sp., Encarsia citrina, Encarsia lounsburyi and Marietta caridei (Aphelinidae); Ammonoencyrtus sp., Cheiloneurus sp., Metaphycus Ismara, Metaphycus sp. and a possible new genus (Encyrtidae); Aprostocetus sp.1, Aprostocetus sp. 2 and Tetrastichus sp. (Eulophidae); Eupelmus sp. and Lecaniobius sp. (Eupelmidae); Eurytoma sp. (Eurytomidae); Tomocerodes americanus (Pteromalidae) and Signiphora sp. (Signiphoridae). Individuals of all species of scale insect were parasitized and S. oleae had the greatest parasitoids diversity associated, however, it had the lowest rate of parasitism.

Full textXylella fastidiosa is a gram-negative bacterium that colonizes the xylem vessels of plants and may be pathogenic to some crops. This bacterium is transmitted by leafhoppers (Hemiptera: Auchenorrhyncha) from the superfamily Cercopoidea (Aphrophoridae, Cercopidae and Clastopteridae) and family Cicadellidae (subfamily Cicadellinae). In Italy this phytopathogen is causing a new disease in olive trees, named \'olive quick decline syndrome\'. Recently, the occurrence of this bacterium associated to a \'leaf scorch\' was also detected in Argentina and Brazil. Thus, it is necessary to carry out surveys of Auchenorrhyncha species in olive orchards in the region of the Mantiqueira Mountain Range, where the olives are grown in the states of São Paulo and Minas Gerais, at 800 to 1800 m altitude range. The objectives of this work were to do faunistic analysis of Auchenorrhyncha species, to measure species similarity of the community of Auchenorrhyncha among orchards, and to indicate possible vectors of Xylella fastidiosa in olives. Seven olive orchards located in the Mantiqueira Mountain Range were selected, following an altitudinal gradient: Wenceslau Braz (MG-1780 m), São Bento do Sapuccaí (EntreVilas) (SP-1602 m), São Bento do Sapucaí (São José) (SP-1512 m), Maria da Fé (MG), with three orchards (area of Lago-1329 m, area of Suíça-1318 m, area of Atemoia-1310 m) e Cabreúva (SP-883 m). Nine yellow stick traps were installed in each orchard at two heights, 0.8 m and 1.6 m above soil level, totaling 18 cards per orchard, which were replaced fortnightly from June/2015 to May/2017. A total of 40,324 individuals from 270 species included in Auchenorrhyncha were collected, distributed in 12 families, with the highest frequency of individuals in the group Cicadellidae (68%) and group Cicadellinae (43% of all Cicadellidae). The faunistic analyses classified 44 species as predominant, 20 belonging to groups of possible vectors of X. fastidiosa. Among them, the species Clastoptera sp. 1 (family Clastopteridae), Macugonalia cavifrons and Scopogonalia sp. 1 (subfamily Cicadellinae) are predominant in all orchards, except in the Cabreúva orchard. Nymphs of Clastoptera sp. 1 were observed developing on young olive branches. Higher diversity, richness and equitability indices were observed in Wenceslau Braz, São Bento do Sapucaí (São José) and São Bento do Sapucaí (Entre Vilas) orchards, respectively. Jaccard\'s greatest similarity was found between Maria da Fé orchards (55%). The greatest similarity of Morisita was found between the orchards of São Bento do Sapucaí (São José) and Maria da Fé (91%) and the lowest one between orchards of Cabreúva and São Bento do Sapucaí (Entre Vilas) (6%). For some predominant species of Cicadellinae and Cercopoidea, capture efficiency was influenced by trap height on the olive tree canopy.

Full textBrazil has a large consumer market for olive-derived products (Olea europaea L.); however, this new culture requires further technical investigation. Therefore, the determination of an efficient method of propagation is the first step in obtaining sufficient amount of plants for the establishment of a sustainable production system. Due to the lack of information surrounding the olive propagation, especially in Brazil, the present work aimed to improve the efficiency of the vegetative propagation by rooting of semi-hardwood cuttings and whip grafting. The trial was carried out at Embrapa Clima Temperado, Pelotas/RS, and it was divided into three experiments. The first one aimed to obtain information about performance of different substrates (Perlite, Vermiculite and Plantmax) to promote rooting of olive 'Frantoio'. It was evaluated the rooting of cuttings (%) and/or callus formation (%) and quality of rooting (root amount grown). The second experiment aimed to evaluate the rooting of semi-hardwood cutting of Olives 'Arbequina' and 'Arbosana' submitted to different sources and concentrations of auxin (0mg.L-1, IBA 2000mg.L-1, IBA 4000mg.L-1, NAA 250mg.L-1 and NAA 500mg.L-1). Also, it was evaluated the rooting of cuttings (%) and/or callus formation (%) and quality of rooting (root amount grown). The third batch assessed the behavior of different olive cultivars (Itrana, Tanche, Bosana, Barnea, Manzanilla, Seggianese, Canino, Picual, Taggiasca and Cipressino) grafted on privet. The measurements here were living grafts (%), shooting grafts (%), number of shoots and length of shoots (cm). It was verified that: in the first experiment the substrate associated with the use of IBA (2000mg.L-1), has no influence on the amount and quality of roots formed on semi-hardwood cuttings of olive 'Frantoio'. In the second experiment, olive cuttings of 'Arbequina' and 'Arbosana' reached up to 18.64% of rooting, indifferently of auxin source and concentration. Rooted cuttings of olive 'Arbequina' and 'Arbosana', untreated and treated with butyric acid (IBA) and naphthaleneacetic acid (NAA), showed low quality of rooting (around one to four main roots). In the third experiment, regarding whip grafting of olive grafts on privet tree, there are considerable variations among living grafts (grafts that remain green but without shooting), grafting set (grafts that show shoots and union between scion/rootstock), number and average length of shoots. The highest grafting set rates and number of shoots per olive graft on privet, occur after 120 days of grafting.
O Brasil apresenta amplo mercado consumidor para os produtos derivados da oliveira (Olea europaea L.), porém, esta nova cultura, necessita de maiores conhecimentos técnicos. Assim, a determinação de um método de propagação eficiente é o primeiro passo na obtenção de quantidades de mudas suficientes para a implantação de um sistema de produção. Em conseqüência da falta de informações que envolvem a propagação de oliveira, principalmente no Brasil, realizou-se o presente trabalho com o objetivo de melhorar a eficiência da propagação vegetativa por enraizamento de estacas semilenhosas e enxertia de garfagem. Foram conduzidos na Embrapa Clima Temperado, Pelotas/RS, três experimentos, sendo o primeiro para obter informações sobre o potencial de diferentes substratos (Perlita, Vermiculita e Plantmax) para promover o enraizamento de estacas de oliveira Frantoio‟. Avaliou-se o enraizamento de estacas (%) e/ou formação de calo (%) e qualidade de enraizamento (quantidade de raízes emitidas). No segundo experimento objetivou-se avaliar o enraizamento de estacas semilenhosas de oliveiras Arbequina‟ e Arbosana‟ submetidas a diferentes fontes e concentrações de auxina exógena (0mg.L-1, AIB 2000mg.L-1, AIB 4000mg.L-1, ANA 250mg.L-1 e ANA 500mg.L-1). Também avaliou-se o enraizamento de estacas (%) e/ou formação de calo (%) e qualidade de enraizamento (quantidade de raízes emitidas). O terceiro teve-se como objetivo, avaliar o comportamento de diferentes cultivares de oliveira (Itrana, Tanche, Bosana, Barnea, Manzanilla, Seggianese, Canino, Picual, Taggiasca e Cipressino) enxertadas sobre ligustro, sendo avaliados os enxertos vivos (%), enxertos brotados (%), número médio de brotações e o comprimento médio das brotações (cm). Através dos resultados obtidos verificou-se que: no primeiro experimento, o tipo de substrato, associado ao uso de AIB (2000mg.L-1), não tem influência sobre a quantidade de raízes formadas em estacas semilenhosas de oliveira Frantoio‟. No segundo experimento, indiferentemente da fonte e da concentração de auxina exógena, estacas de oliveiras Arbequina‟ e Arbosana‟ atingem, no máximo, 18,64% de enraizamento; Estacas enraizadas de oliveira Arbequina‟ e Arbosana‟, não tratadas e tratadas com ácido indolbutírico (AIB) e ácido naftalenoacético (ANA), apresentaram baixa qualidade de enraizamento, (entre uma e quatro raízes principais). No terceiro experimento, verificou-se que na enxertia de garfagem de oliveira sobre ligustro, existem consideráveis variações entre enxertos vivos (enxertos que permanecem verdes, porém sem apresentar brotação), pegamento de enxertos (enxertos que apresentam brotações e união entre enxerto/porta-enxerto), número e comprimento médio das ii brotações. O maior pegamento e número médio de brotações por enxerto de oliveira sobre ligustro, ocorrem após 120 dias de realização da enxertia.
