Resumo: A aplicação do processo de microfiltração para clarificação de certos sucos de frutas tem demonstrado resultados economicamente viáveis. Inúmeros sucos de frutas típicas do Brasil ainda não foram testados neste tipo de processo, visando a sua clarificação. Suco de tamarindo (Tamarindus indica L.) reconstituído na proporção de 1 de polpa para 3 de água foi microfiltrado a 35ºC, em membrana tubular de polipropileno de diâmetro médio de poro de 0,2 µm, variando-se as condições de pressão transmembrana, velocidade de escoamento e utilizando ou não um pré-tratamento enzimático da polpa. Foram observados fluxos finais de permeado de 70 a 115 kg/m2h. O aumento da pressão transmembrana aumentou o fouling, mas resultou em altos valores de fluxo de permeação, tanto iniciais quanto finais. Alta pressão associada ao uso de enzima pectinolítica na concentração de 100 ppm apresentou o melhor resultado de fluxo final, a um fator de concentração igual a dois e, conseqüentemente, no menor tempo de processamento. O aumento da velocidade de escoamento e uso de baixas pressões melhorou o fluxo de modo geral, e o uso concomitante de enzima, melhorou ainda mais o fluxo. Ao usar alta velocidade e alta pressão, o fluxo foi elevado no processamento em que não foi feito o tratamento enzimático. Entretanto, no processamento em que foi realizado o tratamento enzimático, o fluxo diminui em 26%, possivelmente devido ao aumento do fouling na membrana. O permeado obtido apresentou uma coloração amarelo ouro, límpido e sem presença de sólidos insolúveis. Houve também retenção de sólidos solúveis (açúcares e pectinas, entre outros) e, conseqüentemente, dos sólidos totais (diminuição da umidade no retentado). Os resultados de fluxo de permeado em diversas condições de operação permitiram uma análise da influência da camada gel e do fouling de acordo com a teoria de resistências em série. Os dados obtidos para a construção da curva de permação foram ajustados a um modelo matemático, baseado na teoria de renovação de superfície, e calcularam-se os valores da constante de declínio de fluxo. Estes foram maiores nos experimentos em que se fez uso de altas pressões e tratamento enzimático
Abstract: Clarification of a lot of fruit juices using microfiltration process has been showing viable economic results. Countless juices of typical fruits of Brazil aren't studied yet in membrane separation process. Tamarind juice (Tamarindus indica L.) reconstituted at 35ºC was microfiltred using a polypropylene tubular membrane of 0,2 µm average diameter poro. The operating conditions of transmembrane pressure, crossflow velocity and enzymatic treatment were evaluated. Final fluxes values of 70 until 115 kg/m2h was observed. The increase in transmembrane pressure resulted in high fouling, but increased the values of inicial and final permeates fluxes. Associated of enzyme pectinolitic at 100 ppm, this experiment presents the best result of final flux and, consequently, the smaller time processing. The increase in crossflow velocity and use of low transmembrane pressure improved the fluxes in general, and using enzymes at the same time, improved the fluxes even more. High crossflow velocities and high transmembrane pressures results in high fluxes just in the experiment without enzymatic treatment. In the experiment where enzymatic treatment was done, the flux reduce 26%, possible due to increase of the fouling on membrane. The permeate presents a gold yellow colour, cloudless and without insoluble solids. There was soluble solids (sugar, pectin etc.) retention and, consequently, total solids retention (reducing of humidity in retentate). The influence of polarized layer and the fouling in several operating conditions results of fluxes allow an analysis by resistance in series theory. The experimental data picked to permeate curve was ajusted to mathematical model based on surface renewal theory and the flux decay constant were calculated. There were higher on experiments with high pressure and enzymatic treatment

Brazil is a country with different biomes and great diversity of little explored vegetal species, and the Cerrado biome is known for the wealth of resources and flora. Among the fruit trees in the Cerrado, the tamarind tree stands out. Its fruit has excellent nutritional properties, but researches involving all the fruit's uses are still insignificant. The objective of this work was to characterize and evaluate tamarind pulp, shell and seeds (Tamarindus indica L.), to develop salted dragees using the flours of the by-products shell and seeds, besides evaluating the nutritional and sensorial quality of the dragees produced. The fruits were collected in Rio Verde and Ceres, Goiás, Brazil, and divided into pulp, shell and seeds. Physical, chemical, nutritional, calorimetry and antioxidant and antinutritional analyzes were performed. The results of this study indicated that the collected fruits obtained a higher proportion of pulp in relation to the residual parts, presented high carbohydrate content and low water activity for the three portions (pulp, peels and seeds) and lower values of ash, lipids and proteins. The shell and seed flours presented high content of total dietary fiber and pulp of the fruit had acid pH and high titratable acidity. The seed flour had a water absorption and solubility index greater than the shell flour, and a lower oil absorption index. The tamarind pulp presented 4 peaks in its thermogram (from 35 to 155 °C), and the tamarind shell and seed flours presented pulp-like behavior after 115 °C with 2 endothermic peaks. All the analyzed fruit portions had high antioxidant capacity, not significantly different from each other. The methanolic extract was more efficient in the extraction of the phenolic compounds of the three portions of tamarind, being the highest content found in the seeds. The tamarind shell showed low toxicity to Artemia salina and the seeds and pulp presented no toxicity. For the antinutritional factors, the tamarind pulp showed the highest nitrate content and absence of trypsin inhibitor. The tamarind seeds presented the highest amount of tannins. For the elaboration of the salted dragee with application of flours of by-products of tamarind was used the design of mixture with six formulations of dragees, where the closest to the commercial in relation to hardness was selected for the sensory and proximal analyzes. The dragee selected had lower instrumental hardness than commercial dragee and low water activity, high lipid, protein and energy value. The addition of flours of tamarind by-products influenced the fiber content, which was higher than in the commercial dragee. The dragee selected was well accepted, with the exception of the appearance attribute and, according to the tasters, would probably buy the new product.
O Brasil é um país com diferentes biomas e grande diversidade de espécies vegetais pouco exploradas, e o bioma Cerrado é conhecido pela riqueza de fauna e flora. Dentre as frutíferas existentes no Cerrado, destaca-se o tamarindeiro. Seu fruto apresenta excelentes propriedades nutricionais, porém pesquisas envolvendo todas as utilidades do fruto ainda são pouco significativas. O objetivo do trabalho foi caracterizar e avaliar polpa, casca e sementes de tamarindo (Tamarindus indica L.), desenvolver drageados salgados utilizando as farinhas dos subprodutos cascas e sementes, além de avaliar a qualidade nutricional e sensorial dos drageados produzidos. Os frutos foram coletados em Rio Verde e Ceres, Goiás, Brasil, e divididos em polpa, cascas e sementes. Realizou-se caracterização física, química, nutricional, calorimetria, antioxidantes e antinutricionais. Os resultados desse estudo indicaram que os frutos coletados obtiveram maior proporção de polpa em relação as partes residuais, apresentaram alto teor de carboidrato e baixa atividade de água para as três porções (polpa, cascas e sementes) e menores valores de cinzas, lipídeos e proteínas. As farinhas de casca e semente apresentaram alto teor de fibra alimentar total e polpa do fruto apresentou pH ácido e alta acidez titulável. A farinha das sementes apresentou índice de absorção e solubilidade em água maiores que a farinha das cascas, e menor índice de absorção de óleo. A polpa de tamarindo apresentou 4 picos em seu termograma (de 35 a 155°C), e as farinhas de casca e semente de tamarindo apresentaram comportamento semelhante a polpa após 115 °C, com 2 picos endotérmicos. Todas as porções do fruto analisadas apresentaram capacidade antioxidante, não diferindo significativamente entre si. O extrato metanólico foi mais eficiente na extração dos compostos fenólicos das três porções do tamarindo, sendo o maior teor encontrado nas sementes. A casca apresentou baixa toxicidade frente a Artemia salina e as sementes e polpa não apresentaram toxicidade. Para os fatores antinutricionais, a polpa de tamarindo apresentou o maior teor de nitratos e ausência de inibidor de tripsina. As sementes de tamarindo apresentaram a maior quantidade de taninos. Para a elaboração dos drageado salgado com aplicação de farinhas de coprodutos de tamarindo foi utilizado delineamento de mistura com seis formulações de drageados, onde o mais próximo do comercial em relação à dureza foi selecionado para as análises sensorial e proximal. O drageado selecionado apresentou dureza instrumental inferior à do drageado comercial e baixa atividade de água, alto valor de lipídeos, proteínas e valor energético. A adição das farinhas de coprodutos de tamarindo influenciou o conteúdo de fibras, sendo este mais elevado que no drageado comercial. O drageado selecionado obteve boa aceitação, com exceção do atributo aparência e, de acordo com os provadores, provavelmente comprariam o novo produto.

Tamaril is a phytomedicine constituded of 5 medicinal plants well known for their laxative proprieties: Cassia fistula (soft extract), Cassia angustifolia (Senna), Coriandrum sativum L. e Glycyrrhiza glabra L. (AlcaÃuz) and Tamarindus indicus L. (soft extract). Every medication to be launched on the market must succeed in a series of research steps, where clinical toxicology evaluation is an important one among them. Genotoxic assessment, which aims on the processes altering DNA integrity, is a relatively recent field in drug development and stands on the interface between toxicology and genetics. This study consisted on the evaluation of clinical safety and genotoxic potential of Tamaril capsules in healthy volunteers. The clinical evaluation consisted of an open study with 25 healthy volunteers of both sexes (13 males and 12 females) who received a daily oral dose of two capsules Tamaril for 28 consecutive days. The volunteers were selected for the study if considered in good health after criterious clinical, physical and laboratorial evaluations. At the end of the 28 study days, blood samples (5 mL) were collected from each volunteer for the genotoxic assessment of Tamaril on peripheral lymphocytes through the comet assay. The mean age of the volunteers was of 30.1 6.9 years and the body mass index was of 24.21Â3.00 Kg/cm2 on the pre-study evaluation and 24.26Â3.05 Kg/cm2 on the post-study. Hematological, hepatic, renal and metabolic functions, as well as sodium and potassium did not show signs of abnormality in any volunteer throughout the weeks of the study. Soften faces, abdominal pain and flatulence were the adverse events regularly observed. Through the comet assay, score 1 DNA damage was most frequently registered on peripheral lymphocytes of volunteers treated with Tamaril (p<0.05). Clinical and genotoxic evaluation of healthy volunteers receiving Tamaril for 28 uninterrupted days did not show signs of toxicity related to the treatment.
O Tamaril à um fitoterÃpico composto de cinco plantas medicinais: Cassia fistula (extrato mole), Cassia angustifolia (Sene), Coriandrum sativum L., Glycyrrhiza glabra L. (AlcaÃuz), e Tamarindus indicus L. (extrato mole); todas com conhecida aÃÃo laxativa. Todo medicamento que vai ser registrado pela AgÃncia Nacional de VigilÃncia SanitÃria (Anvisa), passa por diversas etapas de pesquisa sendo uma delas a toxicologia clÃnica. A genotoxicidade à uma especialidade relativamente recente, e se situa na interface entre a toxicologia e a genÃtica. Esta visa o estudo dos processos que alteram o DNA (Ãcido desoxirribonuclÃico). O objetivo desse estudo foi avaliar a seguranÃa e o potencial genotÃxico da formulaÃÃo de Tamaril cÃpsulas em voluntÃrios saudÃveis. O ensaio clÃnico consistiu de um estudo aberto com 25 voluntÃrios de ambos os sexos, (13 homens e 12 mulheres), que receberam diariamente duas cÃpsulas de Tamaril v.o. por 28 dias ininterruptos. Os voluntÃrios foram incluÃdos no estudo apÃs avaliaÃÃo clÃnica, exames fÃsicos e laboratoriais. Ao final de 28 dias, amostras de sangue (5mL) foram coletadas de cada voluntÃrio, para avaliar o efeito genotÃxico do Tamaril em linfÃcitos perifÃricos humanos atravÃs do teste do cometa. A idade mÃdia dos voluntÃrios foi de 30,1  6,9 anos e o Ãndice de massa corpÃrea foi de 24,21  3,00 Kg/ cm2 no prÃ-estudo e 24,26  3,05 Kg/ cm2 no pÃs-estudo. As funÃÃes hematolÃgica, hepÃtica, renal e metabÃlica, bem como os eletrÃlitos sÃdio e potÃssio foram analisados semanalmente atravÃs dos exames laboratoriais, os quais nÃo evidenciaram sinal de toxicidade, estando todos os resultados dentro da faixa de normalidade. Fezes pastosas, dor abdominal e flatulÃncia foram os eventos adversos mais observados. Pelo teste do cometa, foram observados danos tipo 1 (p<0,05) nos linfÃcitos perifÃricos dos voluntÃrios tratados com TamarilÂ. Os estudos de Toxicologia ClÃnica e genotoxicidade nÃo evidenciaram nenhuma toxicidade nos voluntÃrios tratados com Tamaril por 28 dias ininterruptos 2 cÃpsulas por dia v.o.

Nesta tese foram feitos estudos mais aprofundados de enzimas produzidas pelo fungo Aspergillus tamarii em diferentes contextos de degradação de biomassa lignocelulósica. O primeiro trabalho avaliou a influência de condições de cultivo na ação de celulases e xilanases e demonstrou que ferramentas estatísticas (CCD e CCRD) são necessárias para avaliar o comportamento da enzima em diferentes condições. Os resultados demonstraram que utilização de triptona como fonte de nitrogênio inibiu fortemente a atividade das celulases, enquanto aumentou das xilanases. Além disso, a suplementação com CuSO4 aumentou a atividade de todas as enzimas. Sugere-se que influência dos componentens do meio de culturam devem ser considerados ao fazer um planjamento de coquetel enzimático de fungo. O segundo trabalho avaliou os parâmetros termodinâmicos de uma xilanase pura de baixa massa molecular (22 kDa) de A. tamarii ativa em ácido ferúlico. Após análise de molecular docking de uma xilanase de A. niger com ácido ferúlico, identificou-se que o possível sítio de ligação do ácido ferúlico é no sítio catalítico da enzima. Baseado nisso, foi feita uma avaliação dos parâmetros termodinâmicos de ligação do ácido ferúlico na xilanase de A. tamarii e demonstrou-se que há uma mudança conformacional da enzima na presença do ácido ferúlico, que influencia no encaixe do substrato no sítio catalítico, e dessa forma a enzima se torna ativa ou tolerante. Por fim, dois genes de LPMOs da família AA9 foram clonadas e expressas em Pichia pastoris da linhagem PichiaPink™. As enzimas foram expressas apenas com seus domínios catalíticos. As duas AA9, nomeadas AtAA9.1_SD e AtAA9.2_SD, foram caracterizadas em função da regioseletividade e especificidade ao substrato. AtAA9.1_SD é uma AA9 com oxidação na posição C4 que possui atividade em celulose (PASC), celopentose, xiloglucana e possivelmente xilana e liquenana. AtAA9.2_SD é uma AA9 com oxidação na posição C1/C4 e que possui atividade em celulose (PASC), xiloglucana e possivelmente xilana. Utilizando o fungo A. tamarii como objeto de estudo, mostrou-se que ele possui potencial na aplicação da degradação da biomassa por possuir enzimas com características únicas.
This thesis discusses in-deep studies from enzymes produced by Aspergillus tamari in different contexts of lignocellulose biomass degradation. The first part of this work evaluated the influence of different conditions in cellulase and xylanase activity. Statistic tools (CCD and CCRD) demonstrated their importance to evaluate the behavior of these enzymes in different conditions. The results showed that the use of tryptone as a nitrogen source inhibited cellulase activity while activated xylanase activity. Supplementation with CuSO4 increased activity of both enzymes. The influence of culture medium composition in the enzymatic activity might be considered when designing enzymatic cocktail from fungi. The second part of this work evaluated thermodynamic parameters of a pure low molecular-weight xylanase (22 kDa) from A. tamarii that was active in the presence of ferulic acid. Molecular docking of a xylanase from A. niger with ferulic acid displayed that most probably the ligand interacts with the catalytic site of the enzyme. Based on this, thermodynamic parameters of the xylanase from A. tamarii with ferulic acid were assessed. The results indicated that there was a conformational change of the enzyme in the presence of ferulic acid, and this influenced the fitting of the substrate in the catalytic site, making the enzyme active in or tolerante to the presence of ferulic acid. The last part of this work studied two AA9 LPMOs from A. tamarii. They were cloned and expressed in PichiaPink™. These two enzymes were expressed in a truncated version, with only the catalytic domain, because the vector could not express the proteins’s full length. They were named AtAA9.1_SD and AtAA9.2_SD and were characterized based on their regioselectivity and specificity to substrate. AtAA9.1_SD is a C4-oxidizer with activity in cellulose (PASC), cellopentaose, xyloglucan and probably xylan and lichenan. AtAA9.2_SD is a C1/C4-oxidizer with activity in cellulose (PASC), xyloglucan and probably xylan. This thesis showed that A. tamarii has potential in biomass degradation mainly due to its enzymes with exclusive features.

As práticas de desenvolvimento em computação física embutem dois desafios: a construção do hardware e o desenvolvimento do software. Engenheiros, técnicos e demais especialistas foram historicamente responsáveis pela missão de resolver estes desafios, o que minimizou a necessidade de ferramentas amigáveis para programação e prototipagem em eletrônica. O conhecimento compartilhado de tecnologias e o movimento open-source - para muito além da técnica – impulsionaram o desenvolvimento de produtos fora do modus operandis industrial e o surgimento de desenvolvedores incomuns: artistas, designers e Makers. Diante disso, toolkits como Arduino e Fritzing surgiram para solucionar os desafios. No entanto, muito pode ser feito para acelerar o processo de concepção e prototipagem à esses Makers. tAMARINO é uma proposta de um ambiente visual único e intuitivo para acelerar a prototipagem em computação física. O sistema atua na prototipagem do software e do hardware ao mesmo tempo, o que acelera os primeiros passos. A primeira versão da aplicação foi concebida para microcontroladores Arduino, mas sua arquitetura é extensível a muitas outras placas. A avaliação revelou o sucesso da aplicação em diminuir o tempo necessário para o desenvolvimento de protótipos, reduzindo o time-to-market.

Повний текст джерелаThis thesis explores a relatively new migration pattern of North Americans to Costa Rica and the ways in which these migrants are changing landscapes of belonging and membership in the communities in which they settle. The number of affluent, transnational "amenity migrants" has been growing worldwide in the past decade, yet little is known about their impacts in receiving communities. Through semi-structured interviews with both Costa Ricans and North Americans in Tamarindo, Costa Rica, textual analysis of newspaper publications, and participant observation, I argue that North American amenity migrants are reworking the parameters of citizenship and democracy in Costa Rica. Even though they are not legally entitled to participate in the political process, foreign amenity migrants' economic power radically transforms social and cultural landscapes in Tamarindo. In addition, these affluent amenity migrants influence political decision-making processes in ways that often marginalize local Costa Ricans economically, politically, and culturally.

Повний текст джерелаA position beaconing system for tracking small mammals, such as the Golden Lion Tamarin, was developed and tested. GPS acquires location of the animal. The system utilizes a VHF radio transmitter tuned to 144.390 MHz, which is located in the amateur radio band. APRS was selected as the protocol for position, transmission, and recovery. This allows users to benefit from any existing APRS enabled devices. The beacon was designed by attempting to optimize operational longevity and minimize size. Consequently, the system is implemented on a single board and enclosed for protection. As the system must be comfortable for the mammal, it was manufactured from lightweight components and enclosed in a plastic housing. To attach the case to the mammal, it is connected to a flexible, zig-zag, wearable antenna, which functions as a collar.

O ergosterol tem papel fundamental na estrutura e função da membrana plasmática de fungos. Ele tem sido utilizado como marcador da biomassa fúngica, pois sua variação no tempo está associada à variação de biomassa. Diversos métodos de extração de ergosterol são reportados na literatura. Vários autores têm reportado o uso de delineamentos experimentais para otimizar procedimentos relacionados ao ergosterol, como a extração, cultivo de fungos ou a seleção de substratos para cultivo. Este trabalho teve por objetivo desenvolver e otimizar um método de extração assistida por micro-ondas de ergosterol de Aspergillus tamarii cultivado na presença de casca da maracujá-amarelo (CMA) como fonte de carbono (FC) e determinar o perfil de crescimento de A. tamarii pela quantificação do ergosterol. A massa de ergosterol extraído dividida pela massa inicial de amostra (µg/mg) foi usada como resposta nos experimentos de otimização. A triagem de variáveis da extração indicou que tempo de irradiação, volume de pentano e massa de amostra afetaram a resposta significativamente Um planejamento fatorial 23 foi modelado pela Metodologia de Superfície de Resposta (RSM) para maximizar a quantidade de ergosterol obtida. Os valores ótimos encontrados foram de 45 s de irradiação, 50 mg de amostra e 10 mL + 5 mL de pentano. A análise de ergosterol por HPLC-DAD apresentou tempo de retenção de 2,8 minutos e não foi observada co-eluição. O método apresentou boa linearidade (r2>0,999; 0,01 – 200,00 µg/mL) e precisão (CV<8.77%) em todas as análises. O ergosterol apresentou uma forte correlação com a biomassa de A. tamarii, além de aparentar ter alguma associação com a biomassa fúngica e a atividade de pectinase em função do tempo de crescimento.
Ergosterol plays an important role to the structure and function of the membrane. It has been used in many studies as a marker of fungal biomass. Several methods of ergosterol extraction are found in literature. Authors have also reported the use of experimental designs to optimize procedures related to ergosterol, such as extraction, fungi cultivation or selection of different substrates. In this work, we aimed to develop and optimize a microwave-assisted extraction method of ergosterol from Aspergillus tamarii grown in the presence of passion fruit peel as carbon source and use the ergosterol production profile to determine the growth curve of A. tamarii. Ergosterol mass divided by initial sample mass (µg/mg) was used as response in optimization experiments. Preliminary selection of variables indicated that irradiation time, pentane volume and sample mass significantly affected the response. The data from a 23 factorial design were used to maximize the amount of ergosterol obtained in the extraction by Response Surface modeling. Ergosterol separation was achieved at 2.8 minutes and no co-elution was observed. The method has showed a good linearity (r2 >0.999, 0.01 – 200.00 µg/mL) and precision (CV<8.77%) to all analyses. Ergosterol showed to be strongly correlated to both pure fungal biomass and sample mass with residual lignocellulosic carbon source, and it appears to have some degree of correlation to the fungal biomass and pectinase activity along the growth time.

O querosene é um produto derivado da destilação do petróleo, formado por uma mistura de hidrocarbonetos parafínicos e naftênicos. O presente trabalho objetivou avaliar o potencial de Aspergillus tamarii (UFPEDA 870), Curvularia lunata (UFPEDA 885), Penicillium aurantiogriseum (UFPEDA 884), P. corilophylum (UFPEDA 886)e P. griseofulvum (UFPEDA 880), isolados de uma lagoa poluída na região portuária de Suape, Pernambuco, em degradar o querosene. Inicialmente foi feito um ensaio primário de degradação utilizando o indicador redox 2,6 diclorofenol indofenol. Em seguida os fungos foram adaptados em concentrações crescentes de querosene (1% a 30%) e os produtos da degradação foram analisados por fitotoxicidade. Os fungos que se destacaram foram submetidos ao ensaio de bioestímulo, onde foram empregados três meios de cultura: Bushnell-Haas: tradicional (BH1) e modificados com relações carbono:nitrogênio de 50:1 (BH2) e de 100:1 (BH3). Nos ensaios preliminares A. tamarii e P.griseofulvum apresentaram menor tempo de mudança do indicador, com 14 horas de contato e ainda promoveram um efeito sinérgico para com as demais linhagens, quando em consórcio. Nos ensaios de adaptação, os mesmos cresceram em até 30% de querosene, enquanto que as demais linhagens não sobreviveram a concentrações superiores a 5% (C. lunata) ou produziram baixos teores de biomassa (P. aurantiogriseum e P. corilophyllum), a partir de 15%. Nos ensaios de fitotoxicidade, os resíduos da biodegradação por A. tamarii e por P. griseofulvum, causaram menor impacto às sementes de Brassica oleracea var. capitata (repolho roxo) até a concentração de 12%, obtendo-se 62,6% e 83,6% para o índice de germinação, respectivamente, embora todas as sementes tenham germinado. Para os resíduos degradados por C. lunata, P. aurantiogriseum e P. corilophyllum, as sementes não cresceram apenas germinaram, indicando toxicidade dos produtos da degradação. Os experimentos de bioestímulo realizados com A. tamarii e P. griseofulvum, mostraram maior degradação dos hidrocarbonetos alifáticos do querosene no meio de BH 1 para A. tamarii, enquanto que para P. griseofulvum a melhor composição de meio foi em BH 3. Os resultados obtidos destacam A. tamarii (UFPEDA 870) e P.griseofulvum (UFPEDA 880) como microrganismos promissores na biorremediação de ambientes impactados por querosene

Повний текст джерелаMandible form in cotton-top tamarins (Saguinus oedipus) and common marmosets (Callithrix jacchus) provides insight into effects of dietary differences. Mandible shape is due to both genetic factors as well as environmental, with functional differences included in the environmental (Klingenberg and Leamy, 2001). Forces associated with differences in food acquisition can be expected to lead to morphological changes. Common marmosets (Callithrix jacchus ) and cotton-top tamarins (Saguinus oedipus) have different feeding styles, and therefore, have different mandible and other craniofacial adaptations. Whether these taxa are wild-born or lab-born could also affect their mandible form. There is a lack of agreement whether there is sexual dimorphism between these two species, but this study indicates there is sexual dimorphism even after adjusting for size. Standardized lateral and superior views of mandible photographs of both species were analyzed at different mandibular regions and individual dimensions. Not only did it reveal intraspecific and interspecific sexual dimorphism, there is also a difference in mandible form whether a species is wild-born or lab-born. S. oedipus males and females are larger if born in the wild and C. jacchus are larger if born in the lab. This could have implications in the future on how lab-born monkeys are being cared for and fed to better mimic their natural habitat.

Повний текст джерелаCreated by the World Bank, in the midst of the neoliberal policies of structural adjustment, and adopted by the Brazilian state in the 1990s, the model of market agrarian reform represents an attempt at containment of social tensions in rural areas through the demobilization of social movements fighting the land. However, the harmful consequences of these actions go beyond policies. The implementation of this model, called the \"land reform\", is still: the expansion of financial capital in the field, the \"warming\" of the land market and speculation, inaugurates a new mode of recreation of the peasantry, led by the market and creates a conflict between the logic of capitalist private ownership of land and the design of earth work, vision peasant. This research aims to analyze the inclusion of the model of agrarian market reform in the municipalities of Londrina and Tamarana, located in northern Paraná state, through the analysis of agricultural production space of those counties that favored the penetration of the model; of evaluation of rural development policies proposed by the World Bank and adopted by the Brazilian State, and, through the analysis of elements, such as subjecting the income of peasant land to capital, material and social reproduction of families settled and conflicts within the various forms of sociability of the peasants, we see the inevitability of rural settlements created from the agrarian reform programs in the market, lined the neoliberal perspective on rural development under the World Bank.

Повний текст джерелаEsta investigación se centra en reconstruir la historia del Canal de Aragón y Cataluña, inicialmente llamado Canal de Tamarite de Litera, desde sus primeros proyectos hasta su construcción y puesta en funcionamiento a partir de fuentes muy diversas (memorias y proyectos técnicos, disposiciones legislativas, folletos propagandísticos, informes jurídicos, artículos periodísticos, etc.). Los resultados indican que en sus inicios solo buscaba garantizar las cosechas de la comarca de la Litera, después fracasaron diversas iniciativas privadas que esperaban obtener grandes beneficios abasteciendo de cereales el mercado barcelonés y, por último, jugó un papel clave en la creciente implicación del Estado español en el proceso de modernización agraria a través de la política de fomento a la irrigación. La llegada del agua no fue la panacea para resolver la “cuestión agraria” que muchos esperaban. Sin embargo, permitió un sensible incremento de la producción agrícola y potenció una progresiva articulación económica y espacial de la zona regable.
This research focuses on reconstructing the history of the Canal of Aragon and Catalonia, initially called Tamarite de Litera Canal, in the years between the first projects, the construction and the start up. A wide range of documentary sources has been used: technical memories and projects, legislative orders, advertising leaflets, legal pleas, newspaper articles, etc. The evidence points out that initially its mere use was only to ensure the crops of the Litera area. Later, some private enterprises which wanted to obtain big benefits by means of providing Barcelona market with cereals failed, and finally it had a key role in the growing involvement of the Spanish Government in the agricultural modernization process through foster the irrigation policy. The results demonstrate that the water arrival was not the expected panacea to solve the "agrarian question". Nevertheless, the Canal allowed a noticeable increase of the agricultural production and it enhanced progressive economic and spatial articulation of the irrigated area.

Повний текст джерелаTamarixia radiata (Waterston, 1922) is one of the major biological control agents of Diaphorina citri Kuwayama, vector of huanglongbing, in Brazil. This parasitoid has been very effective due to the high parasitism rates, high dispersal ability and high establishment and adaptation rates in the field. However, the efficiency of T. radiata may be affected by the indiscriminate use of pesticides to control many other citrus pests and due to the lack of studies that evaluated the total impact of pesticides. Therefore, the objectives of this research were to evaluate the lethal and sublethal effects of some insecticides on T. radiate adults and pupae. Besides mortality, the effect of insecticides on parasitism capacity, longevity, sex ratio and instantaneous rate of increase of T. radiata were also evaluated. The insecticides evaluated were imidacloprid (neonicotinoid), lambda-cyhalothrin (pyrethroid) and abamectin (avermectin) at recommended rates of 96; 7.5 e 3.2 mg of active ingredient per liter of water (ppm) respectivelly, plus 10 e 50% of recommended rates of each insecticide. A residual contact bioassay was used by spraying the insecticide onto orange leaf discs with Potter tower. The effect of abamectin was also evaluated on parental and F1 generations of T. radiata by spraying the insecticide on branches of Murraya paniculata (L.) Jack and on pupae of T. radiata by direct contact bioassay. The highest toxicity to T. radiata adults was observed with imidacloprid (72.7% mortality), followed by lambda-cyhalothrin (19.4%) and abamectin (3.0%). Abamectin promoted the highest reduction in the parasitism capacity (28.8%), followed by imidacloprid (31.3%) and lambdacyhalothrin (40.1%) at recommended rates of each insecticide. The insecticides tested did not affect the sex ratio of the parasitoid. Lambda-cyhalothrin did not affect the longevity of the parasitoid. On the other hand, imidacloprid caused reduction in the longevity. A reduction of 56 and 80% in the emergence of offspring of parental generation was obtained at 50 and 100% of recommended rate of abamectin. However, no effect was observed to the offspring of F1 generation. The longevity of males from the parental generation was reduced in 8.4 days at 50% of the recommended rate of abamectin; however, no significant effect was detected to F1 generation of the parasitoid. There was effect on parasitism capacity of the parental and F1 generations of the parasitoid when abamectin was sprayed on M. paniculata. However, abamectin affected the emergence of offspring from parental and F1 generations of T. radiata, with values varying from 24.4 to 84.2% and 0 to 95.1% respectively. Abamectin affected the sex ratio of both generations. A decrease in the longevity of the parasitoid was observed at 10, 50 and 100% of recommended rate of abamectin to the offspring of parental generation and only at 50% of recommended rate to the offspring of F1 generation. Abamectin did not affect the adult emergence and neither the sex ratio when abamectin was applied on T. radiata pupae. And, abamectin did not affect the instantaneous rate of increase of T. radiata at all concentrations tested.

La distribución de tamaño de partícula para M1 exhibieron un carácter unimodal, con intervalos de diámetro de ~1 a 50 μm mientras que la distribución de M2 tiene diámetros en el intervalo de ~1 a 50 μm y una variación en la distribución en el intervalo de ~50 a 125. Las microcápsulas del sistema M1 son térmicamente estables hasta una temperatura de 227 °C mientras que las del sistema M2 son estables hasta 178 °C. Los patrones de difracción de rayos X para M1 y M2 muestran un dominante halo amorfo. La eficiencia de encapsulamiento para las microcápsulas del sistema M1 presentaron un valor de 89.75% y para las microcápsulas del sistema M2 un valor de 81.31%. Se permitió liberar al aceite encapsulado a tasas de liberación controladas donde el empleo de una mayor proporción de material encapsulado, como lo es en el caso M2, conllevo a una liberación más acelerada del aceite en los primeros 100 minutos. En general, los resultados llevan a concluir que el mucilago de tamarindo puede ser empleado como agente encapsulante viable para obtener una alta eficiencia de microencapsulación.

O nordeste apresenta deficit hídrico e precipitações pluviométricas irregulares, além de altas temperaturas, exigindo para a exploração agrícola racional, o uso de irrigação. A reduzida disponibilidade no semiárido, de água de boa qualidade para irrigação, muitas vezes, torna necessário o uso de águas salinas, ficando esse uso na dependência de desenvolvimento de técnicas que tornem possível a exploração agrícola sustentável ou seja, sem agredir o meio ambiente.Com isso, objetivou-se com está pesquisa avaliar a produção de mudas de tamarindo cultivar Crioula irrigadas com águas salinizadas ob adubação nitrogenada. O experimento foi desenvolvido em ambiente protegido (casa de vegetação) no Centro de Ciências e Tecnologia Agroalimentar da Universidade Federal de Campina GrandePombal-PB. O delineamento experimental utilizado foi em blocos casualizados, num esquema fatorial 5 x 4, com quatro repetições e duas plantas por parcela. Os tratamentos consataram de cinco níveis de condutividade elétrica da água de irrigação (0,3; 1,3; 2,3; 3,3 e 4,3 dS m-1) em quatro doses nitrogenio (70, 100, 130 e 160%).A dose de 100% corresponde á 600 mg de nitrogênio dm3. mudas de tamarindo). A produção das mudas foi avaliada através das distintas variáveis de crescimento: altura de planta, diâmetro do caule e número de folhas no período de 90 dias após a aplicação dos tratamentos (DAT)e as variáveis de fitomassa fresca e seca de caule, folhas, parte aérea, raiz, e seca total, no período de 135(DAT). Na produção de mudas de tamarindo pode-se usar água de condutividade elétrica de 1,7dS m-1 pois proporciona redução media aceitável de 10% no crescimento. Doses de N variando de 70 a 160 mg de N dm-3 de solo assim como, a interação entre os fatores estudados não promoveram efeito sobre as variáveis estudadas.
The northeast presents water deficit and irregular rainfall, besides high temperatures, requiring for rational agricultural exploitation, the use of irrigation.The low availability in the semi-arid region of good quality water for irrigation often necessitates the use of salt water, and this use is dependent on the development of techniques that make sustainable agricultural exploitation possible, that is, without harming the environment.The objective of this research was to evaluate the production of tamarind seedlings cultivated with Criolla irrigated with salinized waters under nitrogen fertilization.The experiment was carried out in a protected environment (greenhouse) at the Agro-Food Science and Technology Center of the Federal University of Campina Grande Pombal-PB.The experimental design was a randomized complete block design in a 5 x 4 factorial scheme with four replications and two plants per plot. The treatments consisted of five levels of electrical conductivity of irrigation water (0.3, 1.3, 2.3, 3.3 and 4.3 dS m-1) in interaction with four nitrogen doses (70, 100, 130 And 160% The dose of 100% corresponds to 600 mg of nitrogen dm-3 tamarind seedlings).The seedlings production was evaluated through the different growth variables: plant height, stem diameter and number of leaves in the period of 90 days after the application of the treatments (DAT) and the variables of fresh and dry phytomass of leaves, leaves , Aerial part, root, and total dry, in the period of 135 (DAT).In the production of tamarind seedlings, water of electrical conductivity of 1.7 dS m-1 can be used as it provides an acceptable average reduction of 10% in growth. Doses of N varying from 70 to 160 mg of N dm-3 of soil as well, the interaction between the studied factors did not have an effect on the variables studied.

Повний текст джерелаBrazilian agrarian issue, resumed mainly in the 80s and 90s, has motivated several academic studies and governmental programs. Agrarian issue in Brazil should not be analyzed in an isolated way, for it is a means for the strengthening of family agriculture. Rural settlements in Brazil gather 1,432,060 settled families. Consolidation of rural settlements is linked to life quality that settled people aim at in these localities. The productive systems established in the settlements were chosen by the families and they are characterized by diversity of agricultural combinations and family relations. The production systems approach in settlements includes the use and combinations of natural resources, analysis of economic results and social insertion of the family. A prominent municipality in this context is Tamarana in northern Paraná, where 401 families were settled in 17 rural settlements until 2008. So, at first, agrarian, social and economic indicators of this town are presented and after that the results of the research carried out with the settled families are also presented. The purposes of this study were to: carry out a socioeconomic diagnosis in seven settlements, analyze the productive systems of the milk, grain and horticulture, contribute with the study of the agricultural production systems for the establishment of reference networks in settlements and provide information for public policies. The research methodology is based on the Case Study method. The data were obtained by means of individual interviews with 133 settled families, the researcher?s observations and bibliographical research. The quantitative data gathering in the month of May 2006, was organized by the Projeto Redes de Referência para Agricultura Familiar carried out by EMATER and IAPAR. The methodology used for the interviews and the dealing with the data was considered very useful for other cases. The results of the research enabled the observation of social and economic characteristics of the settled families and the great variability of income and production systems. As a whole, social indicators show that the families have access to housing, transportation, consumption goods, health and education at the same level as the most developed settlements in the country. The economic indicators analysis shows that the families with the horticulture systems obtained better results of production gross income and make people busy in agricultural activities. Families with the grain group systems use less intensely the rural areas and have higher income related to other sources than the families of other systems. Families with milk production systems have a lower family income. On the whole, the settled farmers that were surveyed have access to local opportunities, are inserted into the products and services market and have the same difficulties that other similar family groups around them, do.
