Full textObjective. Different products from vegetal origin have been studied due to the fact that they are known as sources of antioxidants, which could be an alternative to the synthetic antioxidants. This research investigated in vitro antioxidant activity of extracts of green and roasted mate (Ilex paraguariensis) and green tea (Camellia sinensis). Methodology. Soluble solid, total phenolics and antioxidant activity were analyzed in aqueous, ethanolic and etheric extracts. Two methods were used: free radical DPPH. (1,1-diphenyl-2-picryhydrazyl) quenching assay and ?-carotene/linoleic-acid oxidation model system. Data were analysed by the standard error estimative of the confidence intervals from average differences. Results. Aqueous and ethanolic extracts presented the highest content of soluble solids. Ethanolic extracts of green tea had the highest phenolic content (13,0mg/mL/EAC), while ethanolic extracts of roasted mate presented the lowest (3,4mg/mL/EAC). All results from DPPH. quenching assay were similar or superior to those found for BHT (synthetic antioxidant). The ?-carotene/linoleic acid oxidation model system showed that the aqueous extract of roasted mate (1,0mg/mL) had an average value 10.1% higher than aqueous extract of green mate, and the roasted mate ethanolic extract (1,0mg/mL) showed higher values (11.7%) than green mate ethanolic extract. Only aqueous and etheric green tea extracts presented lower values when compared to the BHT. Conclusion. It was evident the high antioxidant activity of different extracts from mate (green and roasted) and green tea, indicating the potential use of these herbs as natural antioxidants in food systems.

The advance and spread agricultural frontiers and the necessity to meet the needs of market has lead to a change in the mate-tea growth system in the Southern region of Brazil. Pest problems, previously unnoticed in the extraction system, have increased in importance, due to the implantation of single vegetable species, which has lead to the simplification of the environment, with increasingly larger economical losses. More than eighty animal species feed from different parts of the mate-tea plant. A good management is crucial and it should take into consideration the several factors relevant to this peculiar environment, so that disturbances do not promote populational explosions of some of these species. In the event of any such unbalance, the result would be increased cost and decreased quality of the product. In the context, this study was conducted in Dois Vizinhos town, in the State of Paraná, with the objective of studying the phytophagous mites and their population dynamics, as well as that of their natural predators. For this reason, leaf samples from different parts of the plant have been taken, and the number of mites was counted. This research has been done from August 2001 to July 2002. During this period, two species of phytophagous mites, Dichopelmus notus Keifer, 1960 and Oligonichus yothersi (McGregor), 1914, and three species of predators identified as Euseius concordis (Chant, 1959), Iphiseiodes zuluagai Denmark & Muma, 1972and Agistemus sp. were related to the mate-tea plant. The D. notus mite has appeared in large numbers in mature leaves and in the inferior face of leaves. It was more frequent in the inferior part of leaves belonging to the inferior and medium stratum and in leaves from the internal canopy. On the other hand, O. yothersi has mainly occurred in mature leaves, in their superior face. The concentration of E. concordis e I. zuluagai has been larger in the inferior face of the leaves belonging to the inferior and medium stratum, as well as in the inferior face of the leaves in the internal canopy region, and in the inferior face of mature leaves. D. notus, O. yothersi, E.concordis and I. zuluagai mites have attained the ir highest population numbers in periods of mild temperatures and little rain precipitation. In leaves from the external canopy, the largest population density of Agistemus sp. has occurred in periods of high temperature and heavy rain. There was indication of mutual influence between these species.
O avanço da fronteira agrícola e a necessidade de atender um mercado em crescimento, levaram a uma mudança no sistema de cultivo da erva-mate, Ilex paraguariensis St. Hilarie, na região Sul do Brasil. Os problemas fitossanitários, desapercebidos no sistema e exploração extrativista, começaram a ter importância, pois a implantação do monocultivo levou à simplificação do ambiente e as perdas passaram a ser economicamente significativas. Por ser uma essência nativa, a erva-mate possui mais de oitenta espécies de animais se alimentando de diferentes partes da planta. Um manejo que considere os diversos fatores envolvidos neste agroecossistema particular é fundamental para que perturbações não venham promover uma explosão populacional de algumas destas espécies, podendo aumentar o custo de produção e baixa a qualidade do produto. Neste contexto foi realizado em Dois Vizinhos-PR um trabalho com objetivo de estudar a dinâmica populacional de ácaros fitófagos e seus predadores. Para tanto, foram realizadas de agosto de 2001 a julho de 2002, coletas de folhas de diferentes partes da planta e contado o número de ácaro ao microscópio estereoscópico. Durante o período estudado foram constadas associadas às plantas de erva-mate duas espécies de ácaros fitófagos Dichopelmus notus Keifer, 1960 e Oligonichus yothersi (McGregor), 1914 e três espécies de predadores identificados como sendo Euseius concordis (Chant, 1959), Iphiseiodes zuluagai Denmark & Muma, 1972 e Agistemus sp. O ácaro D. notus ocorreu em maior número em folhas maduras e na face inferior de folhas dos estratos inferior e médio e nas folhas da região interna da copa e O yothersi predominou em folhas maduras e na face superior das folhas. A concentração de E. concordis e I. zuluagai sempre foi maior na face inferior das folhas maduras localizadas nos estratos inferior e médio, na região interna da copa. Os ácaros D. notus, O. yothersi, E. concordis e I. zuluagai tiveram picos populacionais em período de temperatura amena e baixa precipitação pluviométrica. Nas folhas da região externa da copa das plantas a maior densidade populacional de Agistemus sp. também ocorreu na face inferior, mas seu pico populacional ocorreu em período de alta temperatura e precipitação pluviométrica elevada, sendo observado indicadores de influência mutua entre estas espécies.

Full textThis work deals with the influence of the powder and aqueous extracts of C. ambrosioides on the maize weevil, S. zeamais. The powders tested were obtained from leaves, branches, fruits and the whole plant (with fruits), when the plant was in the fructification period. The insects were obtained from a population reared on wheat grains. The effect of the powders from the different vegetal structures and from the whole plant (with fruits) was evaluated concerning the insect behavior (attractiveness and/or repellence), insecticide activity on the immature and adult phases, and the insecticide residual power on the adult phase, with the powder alone and mixed with wheat grains. The insecticide activity of the aqueous extract from the different structures and from the whole plant (with fruits) was evaluated on immature and adult S. zeamais. The results were as follows: a) powders from fruits, branches and leaves of C. ambrosioides are not repellent to S. zeamais adults; b) powders from branches and leaves do not present insecticide activity against S. zeamais adults; c) the compounds with insecticide activity are present in the C. ambrosioides fruits; d) powders from fruits present insecticide residual effect against S. zeamais adults for a period up to 5 days; e) powders from fruits and from the whole plant (with fruits), applied 15 days after initial infestation, present insecticide effect on S. zeamais immature phase; f) the aqueous extracts do not affect the survival and the adult emergence of S. zeamais.

Full textEste trabalho teve como objetivos estimar a biomassa total da erva-mate, produzida na colheita, determinar a concentração de nutrientes nos componentes da biomassa, quantificar os nutrientes exportados na colheita da erva-mate e ajustar modelos matemáticos que quantificassem por meio de equações a biomassa de colheita, residual e total. Inicialmente foram avaliadas trinta parcelas circulares, sendo que cada parcela possuía uma área de 44,18m2. Foram amostradas no total 306 árvores. Nessas parcelas, foram medidas as seguintes variáveis biométricas de cada planta: altura total em metros (ht), diâmetro dos troncos a 0,60 metros acima do solo (d 0.6 metros), raio médio de copa em metros, área de copa em metros quadrados, comprimento médio de copa em metros e avaliou-se a biomassa de colheita composta de folhas mais talos e biomassa residual. Em seguida, em cada parcela amostrada foi avaliada uma planta situada fora desta, que apresentou a média das características dendrométricas das árvores incluídas nas parcelas. Nessas 30 árvores foram determinadas novamente as variáveis biométricas e biomassa de colheita e residual Após isto cada árvore foi decepada ao nível do solo, determinando o peso verde de madeira, casca e raiz . A biomassa área acrescida da biomassa de raízes constitui a biomassa total. Posteriormente retirou-se amostras verdes, de folhas mais talos, resíduos, madeira, casca e raiz as quais foram secadas em estufa, para posterior determinação da biomassa e a concentração de nutrientes. A construção das equações para estimar a biomassa, utilizouse o pacote estatístico Sas System versão 8 . Foi utilizado o método Stepwise de seleção de variáveis independentes, em que se limitou ao máximo a inclusão de três variáveis nas equações selecionadas, e o R2 parcial da variável independente superior a 1% para considerá-la significativa. O teste de seleção de equações foi realizado com e sem intercepto. Os resultados apresentados pelas equações sem intercepto foram superiores às equações com intercepto, tendo sido então desprezado esses últimos. A determinação do teor de nutrientes foi realizada na matéria seca de folhas mais talos, madeira, resíduos, casca e raiz. A biomassa média verde e seca de folhas mais talos, amostradas nas 30 unidades amostrais em kg/árvore e kg/ha foram respectivamente: 7,849; 18577,34; 3,081; 7585,22. A biomassa média verde e seca de resíduos nas 30 unidades amostrais em kg/árvore e kg/ha foram respectivamente: 2,583; 6195,71; 1,009; 3052,01. A biomassa média verde e seca de folhas mais talos, amostradas nas 30 árvores abatidas em kg/árvore foram respectivamente: 7,713 e 3,174. A biomassa média verde e seca de resíduos, amostradas nas 30 árvores abatidas em kg/árvore foram respectivamente: 2,708 e 1,358. A biomassa média verde e seca de madeira, amostradas nas 30 árvores abatidas em kg/árvore foram respectivamente: 13,609 e 6,785. A biomassa média verde e seca de casca, amostradas nas 30 árvores abatidas em kg/árvore foram respectivamente: 1,427 e 0,847. A biomassa média verde e seca de raiz, amostradas nas 30 árvores abatidas em kg/árvore foram respectivamente: 7,678 e 4,693. A biomassa total média verde por árvore abatida em kg/árvore foi de 33,135. A biomassa total média seca por árvore abatida em kg/árvore foi de 16,857. As equações estimadas para as diferentes biomassas secas da erva-mate foram as seguintes: biomassa de madeira = 0,28329.rm + 0,07082.dh2; biomassa de casca = 0,44728.lnm + 1,33596.im2; biomassa de raiz = 2,32270.lnm + 12,81476.im2; biomassa de resíduos = 0,34026.m 2,61245*ln2m + 0,43581.rm; biomassa de folhas mais talos = 0,56043.ac + 2,06004.ln2d; biomassa total = 11,29406.rm + 0,10522.dh2. A biomassa seca total do povoamento foi de 41.078,03 kg/ha, sendo assim distribuídas madeira 16.654,49 kg/ha; raízes 11.973,01 kg/ha; folhas mais talos 7.582,22 kg/ha; resíduos 3.052,01 kg/ha e casca com 2.113,30 kg/ha.

The aim of this work was to quantify the acidic and soluble contents of the essential elements Ca, Mg, N, Cu, Mn and Zn of the toxic elements Al, Cd and Pb in four brands of yerba mate marketed in the city of Lages- SC. Samples of yerba mate (Ilex paraguariensis St. Hill.) Were commercially purchased from supermarkets in the city of Lages, SC. Four brands of commercial yerba mate were selected. All samples have the same date of manufacture, March 2016. The grinding is type PN-1. The samples were oven dried at 65 C ° for 24 h, crushed and sieved in 2 mm mesh. For the total content, the nitro-perchloric digestion was used according to the Manual of Methods of Tissue Analysis used in Embrapa and for the total N, content the sulfur digestion method was used. Infusion was weighed 1.5 g of yerba mate to 10 ml of deionized water, with contact time of 10 minutes, at temperatures of 70, 80 and 90 °C. The quantification of the elements was performed in ICP-OES. On average, the highest levels obtained for all infused elements were at 70 ° C. The nutrients Ca, Mg, N, Cu, Mn and Zn were transferred to the chimarrão. The levels of infused Cd are above the maximum values allowed by the legislation for infusions. However, for Pb content, only the M4 mark is above permitted

The work presented aims to analyze the avoidance of distance learning courses of Profuncion?rio, taught at the Te?filo Otoni headquarters of the Federal Institute of North of Minas Gerais, within the Network e-Tec Brazil. The investigation and evaluation of the factors that lead to the student's decision to give up a distance learning course is the issue relevant to the educational institutions so that, through your knowledge, it can draw effective measures in reducing rates. It was used for such purposes, the case study method, with a qualitative and quantitative approach, through interviews with tutors and coordinators of EaD courses of the Polo Institution headquarters, as well as the dropout students, and documentary research and literature to compose the theoretical framework. The data collected through the survey were analyzed with the support of descriptive statistics, and form the basis for future actions of the institution. From the analysis of the percentage and reasons, the survey revealed that were exogenous aspects of the main causes of evasion in the courses, especially the lack of student?s time to study, do the activities and participate in the course, the overhead and activities accumulation at work, hours of intense work, difficulties in reconciling face meetings with academic Saturdays of the school year and difficulties in following the development of the course.

Full textThis research aims to undertake an analysis the phenomenon of juvenilization of Youth and Adult Education (YAE). Through the bias of Educational Policies in the Light of the Historical Materialist Method, we sought to understand the correlation between the abandonment of normal high school by students and their insertion into the YAE. The questions that permeate the debate are: how it´s configurated an YAE? Is there a relation between the phenomena of juvenilization in the modality and the political referrals of the high School? It was presented as a general objective, understand the juvenilization of the YAE from the analysis of the policy of this modality. While specific objectives, to discuss the relation between YAE and the High School, to raise and analyze the educational data of the National Institute of Educational Studies and Research (NIESR) and to discuss the educational and social impact that they provoke in Brazil. Worked with a qualitative approach based on bibliography, documentary and statistical data. At the end of the analysis it was considered that, although the juvenilization of the YAE was presented as a result of individual psychopedagogical and socials problems of students, the roots of its development are based on the influence of politics and the social structure in the education. It is therefore considered necessary to raise the debate in the various social spaces on the right to education and veiled forms of educational exclusion.

Full textThis study was carried out with the objective of accomplishing an ethnoentomological study with the yerba mate producers of the Municipal district of Salto do Lontra, Southwest area of Paraná, aiming at diagnosing elements for a management project that leads to a contribution towards a solution to the plant health/crop protection, socioeconomic and environmental problems faced by the farmers of the municipal district. Qualitative and quantitative research parameters, such as interviews and collections of insects, have been used with the intention of finding indicators of the answers to the problem of the yerba mate culture decadence in Salto do Lontra. This study wanted to value and to understand the ethnoknowledge of the yerba mate producer, regarding the insects observed in this culture and the cognitions that they have about these insects. It has been observed that the farmers identify and know the insects, classifying them as beneficial or malicious, only when they cause damages to their plantations. Furthermore, it has been diagnosed aspects such as the possibility of the yerba mate to represent an agroecological system, sustainable and viable to the small farmers because it adapts well to the system of agricultural cultures association, and it can be a source of alternative income for the agricultural family. This study has also evidenced the difficulties of the product commercialization in the area, the lack of technical support, the farmers' disorganization, and the need of public politics that foment the local activity of the mate. It has demonstrated that a management project for the culture of the yerba mate will only be effective when it is considered elements such as possibilities of commercialization of the product, financial return for the producer, politics of government incentives, farmers' organization, sustainability of the agroecosystem and, mainly, the respect to the diversity and the exchange of knowledge and practices.

Full textThe Paraguay tea (Ilex paraguariensis) is a plant of economic importance to Brazil, mainly to the southern states, where most production and consumption. The leaves are industrialized aiming at preparing tea, mate, soluble powder, and the obtaining of active pharmaceuticals and cosmetics. The Gyropsylla spegazziniana (Hemíptera: Psyllidae) is considered a pest of Paraguay tea, since it causes hypertrophy of new leaves, giving rise to a symptom known as "Paraguay tea bulb , a structure that houses the nymphs, which feed this site until close to adulthood. The damaged leaves usually fall and reduce crop yield. As the Paraguay tea is consumed practically 'in natura', the use of chemicals is not recommended. The use of insecticidal plants is an alternative for pest control of this culture as it does not pose risks to the environment or to humans. The objective of this study was to test the efficiency of extracts of Eucalyptus spp., Azadirachta indica, Melia azedarach, Cymbopogon citratus, Chrysanthemum spp, Trichilia pallida, Leucaena leucocephala, Chenopodium ambrosioides and Annona squamosa for the control of G. spegazziniana in laboratory conditions. In order to do an initial screening were tested ethanol extracts of 25% aqueous to 20%, and a commercial product based on neem seed (Organic Neem ®), 10%, and selected the ones that caused at least 50 % mortality. The control does not receive any treatment. The extracts were sprayed prior and subsequent to infestation of insects on test plants or twigs of Paraguay tea. In the first stage, the only effective treatment in prior spray was 20% aqueous extract of Chrysanthemum spp (85%). The alcoholic extracts of 25%, using the same method showed better results: A. squamosa (93.6%), T. pallida (90.4%), C. citratus (58.2%), Eucalyptus spp (51.6%) and M. azedarach (64.5%). In the method of spraying later, Eucalyptus spp, and M. azedarach aqueous, with 77.7% and 70.5% respectively, showed potential for insect control. L. leucocephala (100%), Chrysanthemum spp 85.5%), C. citratus (55.5%), A. squamosa (51.6%), C. ambrosioides (55.5%) alcoholics were more effective. After dilution to 10%, only the extract of C. citratus alcoholic and the commercial product, with the method of spraying later showed potential insecticidal, with a mortality rate above 50%.
A erva-mate (Ilex paraguariensis) é uma planta de importância econômica para o Brasil, principalmente para os estados da região Sul, onde se concentram a produção e consumo. As folhas são industrializadas visando ao preparo de chás, chimarrão, pó solúvel, bem como à obtenção de princípios ativos farmacêuticos e cosméticos. A Gyropsylla spegazziniana (Hemíptera: Psyllidae) é considerada uma das principais pragas da erva-mate, pois causa hipertrofia de folhas novas, dando origem ao sintoma conhecido com ampola-da-erva-mate , estrutura que abriga as ninfas, que se alimentam neste local, até próximo da fase adulta. As folhas danificadas geralmente caem e reduzem o rendimento da cultura. Sendo a erva-mate consumida praticamente in natura, o uso de agroquímicos não é recomendado. O emprego de plantas inseticidas é alternativa para o controle das pragas desta cultura, já que não oferecem riscos ao ambiente nem ao ser humano. Assim, o objetivo do presente trabalho foi testar a eficiência de extratos de Eucalyptus spp., Azadirachta indica, Melia azedarach, Cymbopogon citratus, Chrysanthemum spp., Trichilia pallida, Leucaena leucocephala, Chenopodium ambrosioides e Annona squamosa no controle de G. spegazziniana, em condições de laboratório. Para fazer uma seleção inicial, foram testados extratos etanólicos a 25%, aquosos a 20%, e um produto comercial à base de sementes de neem (Organic neem®), a 10% e foram selecionados os que causaram, no mínimo, 50% de mortalidade. O controle não recebeu tratamento algum. Os extratos foram pulverizados prévia e posteriormente à infestação dos insetos-teste nas mudas ou galhos de erva-mate. Na primeira etapa, o único tratamento eficiente, na pulverização prévia foi o extrato aquoso a 20% de Chrysanthemum spp. (85%). Os extratos alcoólicos a 25%, com a utilização do mesmo método demonstraram melhores resultados: A. squamosa (93,6%), T. pallida (90,4%), C. citratus (58,2%), Eucalyptus spp (51,6%) e M. azedarach (64,5%). No método de pulverização posterior, o Eucalyptus spp, e a M. azedarach aquosos, com 77,7% e 70,5% respectivamente, demonstraram potencial para controle do inseto. A L. leucocephala (100%), Chrysanthemum spp 85,5%), C. citratus (55,5%), A. squamosa (51,6%), C. ambrosioides (55,5%) alcoólicos foram os mais eficazes. Após a diluição a 10%, apenas o extrato de C. citratus alcoólico e o produto comercial, com o método de pulverização posterior, demonstraram potencial inseticida, com mortalidade acima de 50%.

To achieve this I argue for a theory of scholarly editing defined by interactivity and I present the XML/TEI encoding method to represent, preserve and manipulate literary texts. I also review the main textual problems in Góngora’s poetry. After studying a selection of witnesses that represent the text of the Solitudes, the result is a critical text of the two versions of the poem; the encoding of the text has been designed to enable the user to access different presentations, explore and navigate the edition in a number of ways and filter the variants according to witness and type.

Full textModern space projects currently under development, such as BepiColombo for the exploration of Mercury or Gaia for space astrometry, have the goal of getting high precision data about their main targets. It is then necessary to conceive several independant relativistic models to perform data analysis ensuring the appropriate treatment of all effects important at the required level of accuracy. The first part of this thesis is dedicated to the study of light propagation. We use the Time Transfer Functions (TTF) formalism to characterize the influence of gravitational light deflection on the Ranging, Doppler and astrometric observables for applications to these future projects. We obtain these observables as integrals depending on the metric tensor and its derivates only. This very general form is particularly adapted to numerical computation and to test of alternative theories of gravity. We also propose several analytical applications of our results up to the 2PM order. In the second part of this thesis, we focus on high precision astrometry in the context of the Gaia mission, scheduled for launch in late 2013. We use an original procedure to get an analytical comparison of our light propagation model with the two approaches developed for Gaia, namely GREM and RAMOD. Following this validation, we use the TTF and the Gaia tetrad developed for RAMOD to simulate a series of astrometric observations within the GSR software. The study is finally completed by the reconstruction of a celestial sphere using 5 years of observations simulated with our model. These applications to astrometry are the result of a French-Italian collaboration between the SYRTE and OATO

Full textThis PHD thesis proposes an assessment of the potential effects of the Economic Partnership Agreement (EPA) between the European Union (EU) and West Africa on Senegalese agriculture and households. Indeed, after 12 years of negotiations, the Economic Community of West African States (ECOWAS) in its majority signed the EPA with the EU, the trade component of the Cotonou Agreement. Thus, the EPA has become the new framework for economic and trade cooperation between the EU and Senegal. The objective to the end is the establishment of a reciprocal free trade area between the EU and ACP countries, however asymmetrical and putting an end to the Lome Agreement, which was based on non-reciprocal trade preferences. This study is based on the Single country computable general equilibrium model (CGE) developed by Bouët et al (2001). It is a static model with the assumption of perfect competition and non-monetary, which describes a small open economy such as Senegal. Indeed, Senegal is a net food-importer developing country and very dependent on international trade specially to cover its food needs. This CGE was enriched by the introduction of the "Dual-Dual" theoretical approach developed by Stifel and Thorbecke (2003) to reflect the specificities of most African economies like Senegal i.e. a large informal sector and migration rural-urban firstly and secondly because almost all the CGE models used to study the Senegalese economy does not incorporate these structural aspects. In addition, to better capture the EPA in our simulations we added two stages in exports and imports modelling to distinguish the origins / destinations ECOWAS and EU. The model is calibrated on a 2006 Social Accounting Matrix (SAM) built as part of this thesis. To understand the effects on households, three household surveys were used to identify 78 representative households. For tariff data, the new ECOWAS Common External Tariff (ECOWAS CET) launched on January 1st 2015 was used. The results revealed that the EPA is a trade reform that offers no real earnings prospects for Senegal because it essentially implies openness of the Senegalese economy only to European products and does not improve the access of Senegalese economy to other economies of the World. In terms of welfare analysis, the EPA did not reduce poverty and inequality

As plantas medicinais têm sido utilizadas para o tratamento paliativo ou curativo de diversas doenças desde os primórdios da humanidade. Portanto, selecionar métodos para propagar e conservar essas espécies é imprescindível. Neste contexto, se insere a espécie medicinal e nativa do Brasil, Varronia curassavica Jacq. conhecida popularmente como erva-baleeira, utilizada na medicina popular como anti-inflamatória, antiartrítica e analgésica, sendo também utilizada como fonte de princípio ativo para o medicamento Acheflan. Esse trabalho teve como objetivos avaliar a propagação por estaquia na presença de ácido indolbutírico (AIB) e o crescimento e parâmetros fisiológicos de plantas de Varronia curassavica Jacq. cultivadas sob duas condições de luminosidade (pleno sol e 75% de sombreamento com tela de coloração azul) por um período de 45 dias. Os resultados obtidos permitem concluir que a propagação vegetativa de Varronia curassavica Jacq. a partir de estacas caulinares retiradas de ramos apicais jovens é otimizada com o uso de AIB, aumentando o número de estacas enraizadas e melhorando o desenvolvimento radicular. As diferentes condições de luminosidade influenciaram as plantas tanto em relação ao crescimento quanto em relação às variáveis bioquímicas analisadas. Nas plantas mantidas sob sombreamento foram observados menor acúmulo de massa seca de raiz e parte aérea e maior área foliar. Foram observados ainda maiores teores de pigmentos fotossintéticos, clorofilas e carotenoides, maior assimilação líquida de CO2 e condutância estomática, porém as taxas de transpiração foram maiores causando uma menor eficiência do uso da água. O sombreamento causou também menores teores de açúcares solúveis, nitrato, aminoácidos e atividade da redutase do nitrato em folhas e raízes. Esses efeitos nos metabólitos primários levaram a uma redução nos teores de compostos fenólicos em folhas e raízes e no rendimento do óleo essencial obtido das folhas. Os resultados apresentados permitem concluir que a espécie em questão apresenta alta plasticidade em relação às condições de luminosidade a que foi submetida.
Medicinal plants have been used for the palliative or curative treatment of various diseases since the earliest days of mankind. Therefore, selecting methods to propagate and conserve these species is imperative. In this context, the medicinal and Brazilian native species Varronia curassavica Jacq., popularly known as erva-baleeira, used in popular medicine as anti-inflammatory, antiarthritic and analgesic, and also used as source of active principle for the drug Acheflan. The aim of this study was to evaluate the propagation using cuttings treated with indolbutyric acid (IBA) and the physiological parameters of Varronia curassavica Jacq. plants, cultivated during 45 days under two conditions of light (full sun and 75% shading with blue net). The results obtained allow to conclude that the vegetative propagation of Varronia curassavica Jacq. from stem cuttings taken from young apical branches is optimized with IBA, increasing the number of rooted cuttings and improving root development. The different luminosity conditions influenced the plants both in relation to the growth and in relation to the analyzed biochemical variables. In the shaded plants, reductions in the dry mass accumulation of root and shoot were observed and an increase in the leaf area. Also, increases in photosynthetic pigments contents, chlorophyll and carotenoid, and a higher net CO2 assimilation rate and stomatal conductance were observed. Transpiration rates were higher in shaded plants causing a lower efficiency of water use. Shading reduced soluble sugars, nitrate, amino acids and nitrate reductase activity in leaves and roots. These effects on the primary metabolites led to a reduction in the phenolic compounds content in leaves and roots and in the yield of the essential oil obtained from the leaves. Results demonstrate that the species presents high plasticity in relation to the conditions of luminosity that it was submitted.

Full textINTRODUCTION AND OBJECTIVES: The bread became, throughout its history, a major food worldwide, and the enrichment of flour making the functional bread has become a practice of recent times. The grape marc Isabel, green tea (Camellia sinensis) and yerba mate (Ilex paraguariensis) are sources of phenolic compounds of considerable value. Popularly, have been studied for offering health benefits, in order to prevent degenerative diseases and for bringing benefits to bakery industries. This study aimed to the addition of Isabel grape pomace extracts, green tea (Camellia sinensis) and yerba mate (Ilex paraguariensis), rich in phenolic compounds wheat flour, to evaluate the effect on the rheology of flour, features technological and sensory. METHODS: To study the effect of phenolic compounds extracted from grape pulp Isabel, green tea (Camellia sinensis) and yerba mate (Ilex paraguariensis) on some properties of wheat flour and bread so it was standardized concentrations of the extracts in flour 1000, 2000, 3000 and 4000 mg GAE / kg and used the method of physical-chemical, rheological and sensory, and the extract: Quantification of compounds; In flour: Moisture, alveography, farinography, falling number and gluten; In the bread: Specific volume, colorimetry and sensory analysis (taste, aroma, texture and overall acceptability). MAIN RESULTS: The yerba mate extract (Ilex paraguariensis) had the highest concentration of phenolic compound, followed respectively by marc Isabel and green tea (Camellia sinensis). All rheological tests with flour grape pomace extract application (EBU) showed improvements in the characteristics desired for baking, as evidenced by the increased gluten strength and water absorption, with a flour with increased tolerance to mechanical stress (stress). The yerba mate extract showed good results when applied in baking, confirmed by the increase in specific volume, the closest color control (white pith) and preferably in the global acceptance of the sensory test attribute. DISCUSSION AND CONCLUSION: The observed differences in rheological properties, physicochemical and sensory in flours and breads made with grape pomace extracts Isabel, green tea (Camellia sinensis) and yerba mate (Ilex paraguariensis) in different dosages, are attributed to interactions by different mechanisms between phenolic compounds and proteins, and those forming the gluten network, directly influencing the strength of flour and gas retention capacity by increasing the volume of the bread.

Full textThe present work aimed the physicochemical and biological evaluation of a saponin enriched fraction from the green fruits of Ilex paraguariensis A. St. Hil. (mate), a species of great economical importance in several Southern American countries, including Brazil. Despite possessing high amounts of saponins, mate green fruits have no commercial use to date and are considered a waste product from the mate leaves processing companies. Mate fruits lyophilized extract (EX40) was produced using turbo-extraction having a 40:60 mixture of water and ethanol as solvent and a 1:10 drug/solvent proportion. An HPLC-UV method was developed and validated aiming at: I) Quantify the EX40 chemical marker, ilexoside II; II) Determine the EX40 total saponin content. The values obtained were of 8.20 wt% and 47.60 wt%, respectively. An enriched saponin fraction (MSF) was obtained from EX40 through a solid phase extraction process within a polyaromatic resin and a decreasing solvent polarity gradient of methanol and water. The higher recovery of mate saponins was achieved with the 70 and 90 % methanol-containing fractions. The process reproducibility was assessed by HPLC-UV through the analysis of the relative standard deviation (RSD) of the two major MSF saponins peak areas obtained in six different batches. RSD values of 8.17 % for peak I (ilexoside II) and 5.96 % for peak II (major peak) were obtained. The MSF toxicity was evaluated according to its haemolytical activity and in vitro cytotoxicity against a mammalian cell culture lineage (MDBK ATCC CCL-22). Values of IC50 of 0.2 g/L (0.22 mM expressed as ilexoside II) and 3.8 g/L (4.04 mM as Ilexoside II) were found for the haemolysis and cytotoxicity respectively. Therefore we could classify MSF as a low toxicity product. Among the several biological activities ascribed to saponins, this work focused on the investigation of MSF immune enhancer potential and its anti-trichomonads vaginalis activity. For the first evaluation, MSF wad added to a bovine herpesvirus 5 vaccine, at 100 and 500 μg doses. However total IGg titres determined by ELISA were not statistically significant. The antitrichomonads activity of MSF was compared a saponin enriched fraction from the species Quillaja saponaria (Quillaja) and to tyloxapol and polysorbate 80. After 24h of incubation MSF presented a dose-dependent activity with total trophozoites lethality at a concentration of 0.6 g/L. The activity was higher than the synthetic surfactants and similar to Quillaja. The treatment with metronidazole (MTZ), peformed in association and after exposing the trophozoites with MSF did not show any synergistic effect of MZT and MSF which suggest an absence of interaction between the compounds and also that they probably have distinct mechanisms of action. The physicochemical evaluation of MSF focused the determination of MSF micelles size and shape, their rheological behaviour and ability to increase the solubility of hydrophobic compounds. MSF critical micellar concentration was determined as 0.41 g/L using a hydrophobic dye as a probe. The transmission electron microscopy (TEM) and CRYO-TEM analysis revealed the occurrence of filiform micelles higher than 500 nm and smaller sizes spherical micelles simultaneously. The spherical micelles radius of 17.9 Å were determined using small angle neutron scattering.and they corresponded to 23.1 and 32.6 % of the total micelles in MSF solutions of 0.5 and 1.0 % w/v, respectively. The rheological behavior of MSF ranging in concentration from 0.25 to 4.0% was determined on a dynamic strain control rheometer and a viscoelastic behavior was observed for all concentrations. These findings corroborate the occurrence of nonspherical micelles very long in size (wormlike). MSF ability to improve the solubilisation of poor aqueous soluble drugs was assessed using carbamazepine (CBZ) and flurbiprofen (FLB) as a model of amphiphilic basic and acidic coumpounds. Saponin enriched fractions were evaluated in concentrations ranging from 0.13 to 1.5 %. Quillaja was more efficient toward the weak acid while MSF was able to increase significantly the CBZ solubility. The increase on CBZ and FLB solubility after MSF addition was of 0.0145 and 0.0129 g/L, respectively.

Full textThis investigation deals with the industrialization process in Paraná, (XX century), particularly on Curitibas grand. The study begins in the 30s, when Brazil entered the period of substitutive industrialization. Then occurred a change from mercantile sources of accumulation to industrial ones. This was performed under the limits of backwarded capitalism. Substitutive industrialization brought with a generalized industrialization process, which in Paraná was based on small amounts of capital from small businessmen that slowly obtained the support of mercantile sources. This, substitutive industrialization moved through the 40s and 50s. In the years of (19)60 the substitutive industrialization came to an end. Then, the process of industrialization in Paraná was reallocated as a complementary function of the vigorous industrialization in São Paulo.

Full textA presente pesquisa foi realizada na linha de Currículo, Ensino e Práticas escolares do Programa de Pós-graduação em Educação da Universidade Federal de Santa Maria/RS. Inicialmente, discuto que, dentre os muitos problemas existentes, na Educação, os quais precisam ser enfrentados, um dos mais marcantes, particularmente na EJA, é a desvinculação entre o mundo da escola e o mundo da vida . Sendo este desencadeador de outros, tais como: o ensino meramente propedêutico, a desmotivação, a falta de significado atribuído ao que se faz na escola, o baixo nível de aprendizagem e o reforço à cultura do silêncio . Entende-se que é possível superar esta desvinculação mediante configurações curriculares balizadas por temas. Assim, assumiu-se como referenciais teóricos pressupostos do educador brasileiro Paulo Freire, referenciais do denominado movimento CTS, como também do educador português Pedro Reis, o qual trabalha com a categoria temas controversos. Este trabalho trata de uma pesquisa de cunho qualitativo, mais especificamente, um estudo de caso quanto à repercussão do tema florestamento no RS, no currículo da EJA. Nesta, o problema de investigação foi definido pelo questionamento: qual tem sido a repercussão do tema "florestamento" no RS, no currículo da EJA? O objetivo consistiu em investigar e identificar possibilidades e desafios a serem enfrentados quanto à implementação deste tema no currículo de quatro escolas, situadas em municípios com intensas plantações de monoculturas ligadas a este megaprojeto, em fase de implantação no Estado. As questões de pesquisa foram: 1) Por que o "florestamento" no RS não repercutiu no currículo da EJA? e 2) Quais os desafios e possibilidades de se estudar este tema, denominado polêmico, no currículo da EJA? Os instrumentos utilizados, para obtenção dos "dados", foram: registros escritos sob a forma de Diários; questionário e entrevistas. Da análise dos resultados, houve a identificação de cinco categorias que constituem desafios a serem enfrentados, quais sejam: 1) Formação excessivamente fragmentada, desvinculada do contexto, 2) Ausência de certezas, de respostas exatas em relação a aspectos polêmicos do tema, 3) "Algo mais", 4) Neutralidade do Professor e, 5) Professor Formador ou Professor Informador. Em termos de sinalização da pesquisa, destaca-se que, para a superação da separação entre o "mundo da escola" e o "mundo da vida", há a necessidade de superação, nos currículos de cursos de licenciatura, da formação fragmentada, unicamente disciplinar, desvinculada dos problemas do entorno, considerando que a complexidade dos problemas contemporâneos não é abarcável por tal formação

Per tant, eines com la Realitat Virtual, amb la capacitat de reproduir entorns amb un elevat grau de realisme, poden ser un context vàlid tant per a l'avaluació com per a la intervenció terapèutica. S'han aplicat entorns virtuals no immersius, donat el rebuig de la població TEA a utilitzar visors RV, malgrat que amb resultats observacionals. Dites limitacions poden superar-se amb l'ús dels anomenats Entorns Virtuals Immersius (EVI), ja que suposen una solució tecnològica no invasiva, amb major capacitat d'immersió i per tant, de generar respostes amb major similitud a les obtingudes en un context real. Les mesures de caràcter observacional poden superar-se amb mesures fisiològiques, tals com, l'activitat electrodermal (EDA), que proporciona la resposta de l'excitació corporal en forma de sudoració enfront d'un estímul o l'eye tracking, el qual mostra el comportament ocular. Ambdues suposen respostes implícites, inconscients i quantificables, que poden ajudar a definir l'afecció. Per tot això, la present Tesi Doctoral, composta de tres estudis, té com a objectiu unir l'ús d'EVI, amb capacitat d'estimulació visual, auditiva i olfactiva amb mesures fisiològiques, focalitzades en l'avaluació i entrenament del TEA, a més d'estudiar les relacions entre les mateixes i les bateries diagnòstiques del TEA. L'Estudi nº 1 va valorar l'adaptació dels participants als dispositius i l'EVI i els nivells EDA en un context de resposta salutació. Els resultats van trobar que els subjectes TEA van mostrar una tolerància similar en l'ús d'EVI i del dispositiu EDA. Van augmentar els seus nivells d'excitació pel que fa a l'estat de repòs prEVI (Ràtio), quan va intervenir el sentit de l'olfacte, no havent-hi relacions significatives amb les bateries diagnòstiques. L'Estudi nº 2 va aprofundir en els nivells EDA en un context d'imitació total o parcial. Els resultats mostraren que els subjectes TEA mostraren una menor activació (Ràtio), davant de processos d'imitació total, amb estimulació olfactiva, no trobant relacions significatives amb les bateries diagnòstiques. L'Estudi nº 3 va estudiar l'EDA i el comportament ocular a un EVI basat en un Centre Comercial. Els resultats EDA, no van proporcionar diferències en la sessió d'avaluació, però van baixar en els subjectes TEA després d'una sessió d'entrenament. El comportament ocular en la sessió d'avaluació va discriminar entre els grups, però en l'entrenament el comportament va ser similar. Les relacions entre aquestes mesures i les bateries diagnòstiques no van mostrar relacions significatives. Com a conclusió final es pot assenyalar que, la mesura electrodermal que va comptar amb major capacitat per a identificar a la població TEA fou la mesura Ràtio. Pel quefa a l'EDA, després de l'entrenament, va ser un indicador d'una millora de l'excitació enfront de situacions d'assenyalament, resposta al nom i atenció conjunta, en el cas del comportament ocular, va ser capaç de diferenciar entre els grups únicament en la sessió d'avaluació. Finalment, l'EDA i el comportament ocular, no van ser mesures amb capacitat correlacional amb les bateries diagnòstiques.
[EN] Autism Spectrum Disorder (ASD) is a complex condition that falls under the category of so-called Neurodevelopmental Disorders. It is characterized by the presence of dysfunctions in social interactions, in the communicative capacity, symbolic thinking, as well as, stereotypical behaviours and deregulation of sensorial character. Currently, given its high prevalence, it has awakened scientific interest in order to carry out earlier diagnoses that will have an impact on more effective interventions. Until now, the diagnosis of ASD has been carried out by means of standardized diagnostic batteries based on qualitative criteria, so that the response may be far from that obtained in a real context. Therefore, tools such as Virtual Reality (VR), with the potential to reproduce highly realistic environments, can be a valid context for both assessment and therapeutic intervention. Non-immersive virtual environments have been applied, given the refusal of the ASD population to use VR viewers, although with bservational results. These limitations can be overcome with the use of so-called Immersive Virtual Environments (IVEs), since they represent a non-invasive technological solution, with a greater capacity for immersion and, therefore, for generating responses that are more similar to those obtained in a real context. Observational measurements can be overcome with physiological measurements, such as electrodermal activity (EDA), which provides the body's response in the form of sweating to a stimulus, or eye tracking, which shows the behaviour of the eye. Both involve implicit, unconscious and quantifiable responses, which can help define the condition. Consequently, the present Doctoral Thesis, composed of three studies, aims to unite the use of IVE, with the capacity of visual, auditory and olfactory stimulation with physiological measures, focused on the evaluation and training of ASD, as well as studying the relationships between them and the diagnostic batteries of ASD. The Study nº1 evaluated the adaptation of the participants to the deviIces and the IVE and the EDA levels in a context of response to the greeting. The results found that ASD subjects showed similar tolerance in the use of the IVE and EDA dEVIce. They increased their levels of arousal with respect to the prEVIous resting state (Ratio), when the sense of smell was involved, with no significant relationship with the diagnostic batteries. Study nº2 studied in depth the EDA levels in a context of total or partial imitation. The results show that the ASD subjects showed a lower activation (Ratio), when facing total imitation processes, with olfactory stimulation, finding no significant relations with the diagnostic batteries. The Study nº3 studied the EDA and the ocular behaviour in an IVE based in a Shopping Centre. The EDA results, did not provide differences in the evaluation session, but they decreased in the ASD subjects after a training session. Eye behaviour in the assessment session discriminated between the groups, but in the training the behaviour was similar. The relationships between these measures and the diagnostic batteries did not show significant relationships. As a final conclusion, it should be pointed out that the electrodermal measure that had more capacity to identify the ASD population was the Ratio measure. While the EDA, after the training, was an indicator of an improvement of the excitement in front of situations of signalling, response to the name and joint attention, in the case of the ocular behaviour, it was one able to differentiate between the groups only in the evaluation session. Finally, the EDA and the ocular behaviour, were not measured with correlational capacity with the diagnostic batteries.

Full textEste trabalho utilizou-se de métodos de estatística descritiva clássica, métodos de geoestatística e de geoprocessamento, na identificação do tamanho e da estrutura da variabilidade espacial de atributos físico-químicos do solo em área de florestamento de erva-mate. A área de estudo, localizada na Fazenda Tupi, no município de Nova Prata, RS, foi levantada amostras nos meses de janeiro a março de 2005, compreendendo a classe de solo Latossolo Húmico Distrófico Álico. Realizou-se amostragem sistemática com grid de espaçamento regular entre os pontos de 100 metros, totalizando 36 pontos amostrais e 630 pares de dados, em uma área de 36 hectares. Foram coletadas amostras de solo in situ para análise em laboratório dos atributos físicos areia grossa (AG), areia fina (AF), silte (SIL), argila (ARG), densidade de solo (DS), densidade de partícula (DP) e porosidade total (PoT) e atributos químicos argila, textura, pH (H2O), fósforo (P), potássio (K), matéria orgânica (M.O.), alumínio (Al), cálcio (Ca), magnésio (Mg), alumínio trocável (H+Al), capacidade de troca de cátions efetiva (CTCe), capacidade de troca de cátions à pH7 (CTCpH7) e saturação de bases (V%). As magnitudes das variabilidades espaciais foram obtidas pelo coeficiente de variação (CV%), com nível de confiança de 95,0%, através do programa Microsoft Office Excel 2003, enquanto que a estrutura foi identificada por meio de semivariogramas, em aplicativos geoestatísticos, definindose os parâmetros necessários para a krigagem. Todos os modelos de semivariogramas apresentaram zonas de influência anisotrópicas, tendo sua variabilidade espacial maior no sentido perpendicular a declividade destas áreas. O atributo químico que apresentou maior variabilidade foi o fósforo (P), com CV%=127,73, seguido do atributo alumínio (Al), com CV%=99,23 e o atributo de menor variabilidade, foi o pH(H2O), com CV%=13,79. Para os atributos físicos, na distribuição do tamanho de partículas (%), o atributo de maior variabilidade foi areia grossa, com CV%=36,39, enquanto a estatística realizada para os atributos densidade do solo, o que apresentou maior variabilidade foi o atributo porosidade total, com CV%=95,49 e a menor variabilidade foi constatada a argila, com CV%=12,32. Na análise de estrutura da variabilidade espacial através da geoestatística, o atributo químico Ca apresentou IDE(%)=64,42 e o atributo físico ARG com IDE(%)=62,50, obtendo os maiores índices. Para realização do ajuste no programa VARIOWIN® 2.21 Software for Spatial Data Analysis , o método utilizado foi o visual, denominado a sentimento , onde o modelo Esférico foi o que melhor se ajustou aos atributos estudados, indicado em 55% dos semivariogramas. O modelo Gaussiano para o atributo textura obteve o maior alcance com a(m)=421. A validação cruzada, com o uso do programa GSLIB 90 Geostatistical Software Library mostrou acuracidade no ajuste dos modelos variográficos, tendo os atributos Ca, Al e ARG com R²(%) de 0,841; 0,705 e 0,760, respectivamente. A krigagem ordinária dos atributos estudados permitiu o detalhamento da distribuição destas a partir dos mapas de isolinhas.

Full textWater pollution by metal species has become a major problem. It is therefore necessary to check the quality of waste and drinking waters. The frequency and parameters of analysis are defined by the European decree -2001-1220 of December 2001. The modification of standards raises difficulties in terms of sensitivity and detection limits of analytical techniques (such as ICPAES) for the quantification of metal species. Introducing a preconcentration step of the analyte before the analysis would be an interesting alternative. Among the various preconcentration methods, chelating solid phase extraction is specially adapted to the extraction of metal species in aqueous media. It involves interactions between a liquid and a porous solid sorbent functionalized by a ligand which generates specific retention of the analyte (Chelation). Many types of solid sorbents can be used for SPE. Synthetic organic polymers and particularly copolymers based on styrene and divinylbenzene (EVB-DVB) meet the expectations of such an application: stability on a wide range of pH, good chemical, physical and thermal properties. To improve the complexing properties of EVB-DVB copolymers, a ligand is required to obtain a chelating porous solid sorbent. In this context, 1,2-benzenediol (catechol) was selected for its ability to retain metal species and because it allows to consider two ways of incorporation: 1. Grafting of catechol on commercial EVB-DVB copolymer (Amberlite® XAD4, Rohm and Haas) via reduced imine and diazonium bridges; 2. Suspension copolymerisation of a styrenic monomer containing catechol with divinylbenzene. The functionalized solid sorbents resulting from both elaboration methods were characterized by TGA-DSC, FTIR spectroscopy and Py-GC/MS to validate the incorporation of catechol. The complexing properties for Cd(II), Cu(II), Ni(II) and Pb(II) were determined by ICP-AES and compared with functionalization rates (assessed by acido-basic back titration of hydroxyl functions of catechol) and textural properties (surface area, pore volume, pore diameters determined by gas adsorption/desorption). In comparison to grafting, the suspension copolymerization allows to vary the ligand quantity introduced, to keep the sphericity of beads and control particle size, reducing the cost and constraints of implementation. This elaboration process has led to original materials (less colored) that open up prospects, particularly in terms of application: direct detection of retained metals by diffuse reflection spectroscopy

Full textL'approche retenue repose sur l'idée qu'il existe une solution générique aux problèmes d'ingénierie. Notre proposition est de formaliser cette solution pour permettre de l'adapter ensuite à des domaines d'activités et à des projets précis par des opérations de transformation de modèles. Pour cela, nous nous reposons sur les concepts de l'IDM et les appliquons dans le cadre de l'ingénierie système. Les étapes de notre proposition sont :
• la formalisation d'un processus générique à partir d'un standard de l'ingénierie système (EIA-632) sous la forme d'un modèle SPEM/UML,
• sa spécialisation pour l'adapter au contexte d'application d'un projet,
• son enrichissement pour en préparer l'exploitation et la conduite. La formalisation des processus est la base d'une démarche nouvelle d'application de l'ingénierie système.
Cette démarche assure une cohérence globale et locale dans l'organisation et le déroulement des projets. En se reposant sur des règles de bonnes pratiques issues des standards internationaux elle s'assure d'un comportement global cohérent du projet. En laissant les acteurs du projet libres d'adapter leurs pratiques à leur environnement de travail elle permet à chacun de travailler de manière optimale avec l'assurance que les processus spécifiques qu'il emploie s'insèrent au mieux dans le projet.
La démarche que nous proposons répond à la problématique d'application concrète des processus d'ingénierie système posée par l'industrie et, plus généralement, à celle de l'amélioration continue des méthodes et des produits.
