Les gestionnaires forestiers sont demandeurs d'une aide à la décision pour la conservation du mélange Sapin et Epicéa en forêt de montagne. Pour répondre à leur attente, nous avons modélisé, pour les deux espèces, les fonctions démographiques (croissance, mortalité et recrutement) et les fonctions d'allométries à partir de données de terrain. Ces fonctions ont été implémentées dans un modèle de dynamique forestière afin d'améliorer les connaissances sur la dynamique naturelle des deux espèces et d'envisager des tests de scénarios sylvicoles. L'estimation statistique des paramètres des modèles a été effectuée dans un cadre bayésien hiérarchique. Elle a permis de mettre en évidence et de quantifier les différences entre espèces : le Sapin, espèce tolérante à l'ombre comparativement à l'Epicéa, est moins sensible à l'autoéclaircie, a une croissance plus forte et un taux de recrutement plus important à faibles niveaux de lumière que l'Epicéa. Les modèles développés ont pris en compte l'incertitude sur les observations et la variabilité spatio-temporelle des processus. La variabilité individuelle (ou intraspécifique) et temporelle (interannuelle et intra-individuelle) est forte et tend à égaliser la fitness des deux espèces en inversant la hiérarchie des espèces localement dans l'espace ou sporadiquement dans le temps. Les premières simulations à l'aide du simulateur Samsara2 indiquent un meilleur comportement du modèle lorsque la variabilité spatio-temporelle est inclue dans les processus. La variabilité assure une structuration en hauteur et en diamètre ainsi qu'une évolution de la surface terrière qui correspondent à des patterns plus réalistes que lorsque la variabilité n'est pas prise en compte. A l'issue des premières simulations sur un peuplement test en mélange, on observe une exclusion compétititve systématique de l'Epicéa par le Sapin. Les mécanismes égaliseurs associés à la variabilité ne parviennent pas à contrebalancer l'avantage compétitif du Sapin sur l'Epicéa. Toutefois, la dynamique transitoire du système est lente et la coexistence apparente des deux espèces peut s'étaler sur plusieurs centaines d'années.

This work intends to describe the present condition of Vallombrosa forest (Tuscany, Italy) from the phytopathological point of view. The chronic disease caused by Heterobasidion and Armillaria root rots is a key factor affecting the vitality of silver fir plantations of the region. Detailed knowledge about their distribution could help to control the pathogens. Systematic sampling and survey of damages on trees were undertaken at 52 points. Identification of different species from soil and fungal samples was accomplished by DNA-based methods (TSCP, nested PCR, RFLPs analysis). The high presence of both parasitic fungi was detected under a wide range of ecological conditions. Data analysis indicates the strong spreading potential of the pathogens even into new habitats, especially in connection with water stress of their hosts.

Home range size of Oregon birds and range sizes of individuals wintering in coastal areas of California and Peru were compared to determine if annual migration distance from the high arctic breeding ground is positively correlated with home range size. Oregon sanderlings on average remained within a minimum range of 17 kID during the nonbreeding season from October thrcugh April, although spring data are sparse. The Oregon home range is significantly larger than that of birds in Bodega Bay, California, and similar to that of birds in Peru. Therefore home range size is not correlated with distance from the breeding ground.

Para isso, analisei as relações entre vida e linguagem, o combate corpo a corpo que ele sus-tentou em toda a sua pequena e significativa produção: a poesia reunida em A noite di-vidida e os manuscritos publicados postumamente nos livros Albas e Ventos da minha alma. No dualismo dialógico entre vida e obra, ressaltei aspectos como o ritmo fundan-te, a ideia-metáfora da supracasa, a metalinguagem, que se ampliam na dupla Sebastião Alba-Dinis Albano, como personagem de si mesmo. Defendo que o poeta luso-moçambicano entrelaça o fazer poético com sua visão de mundo e sua postura existen-cial efetiva – a imagética conciliada ao ritmo original conquistado na escrita. O homem não se descola do conteúdo da obra. Assim, o termo supracasa significa um lugar outro que não se encontra localizado no território geográfico onde a sociedade civil se institui. Analisei os tópicos reincidentes encontrados na obra poética: a representação da paisa-gem, a vibração amorosa, a simbologia dos pássaros e a tensão entre imanência do mundo e transcendência vazia. / Dans cette thèse, j’ai traité de certains aspects de l’oeuvre plus personnelle du poète por-tugais-mozambicain Sebastião Alba, pseudonyme de Dinis Albano (1940-2000). Pour cela, j’ai analysé la relation entre la vie et la langue, la lutte qu’il a soutenu en toute sa petite et significative production: la poésie rassemblé en A noite dividida et les manus-crits publiés à titre posthume dans les livres Albas et Ventos da minha alma. Sur le dua-lisme dialogique entre la vie et l’oeuvre, j’ai souligné l’aspects comme le rythme fonda-teur, l’idée-métaphore le supracasa, le métalangage, qui s'étendent dans le double Se-bastião Alba-Dinis Albano, comme personnage de lui-même. Je soutiens que le poète mozambicain-portugais amalgame le faire poétique avec leur vision du monde et sa pos-ture existentielle effective – l’imagerie conciliée avec le rythme original conquis par l’écriture. Cet homme n’a pas se détaché du contenu de son oeuvre. Ainsi, le terme su-pracasa signifie un lieu autre que n’est pas situe sur le territoire géographique où la société civile s’institue. J’ai analysé les thèmes récurrents trouvé dans l’oeuvre poétique: la représentation de le paysage, le frisson amoureuse, le symbolisme des oiseaux et la tension entre l’immanence du monde et la transcendance vide.

The relative amount of viral RNA of two comoviruses (RaMV and TuRSV) in different parts of plant during infection was determined. The two viruses were compared according to their ability to spread and multiply in plants.

The lung carcinomas stand out as a major public health problem, therefore, are among the leading causes of cancer death worldwide. They are classified into two major histological groups: small cell lung carcinome (SCLC) and non small cell lung carcinoma non (NSCLC). In the search for novel therapies, many natural products derived from plants and other organisms has been studied for use as a source for the development of chemotherapeutic agents used in the treatment of various cancers, including carcinomas of the lung. In this context, the essential oils is part of medicinal plants produced by such as the genus Lippia that have many therapeutic properties, among them, antimicrobial, anti-inflammatory and antiproliferative. This study proposes to investigate the cytotoxic activity of essential oils of different species and genotypes of the genus Lippia plants. the Active Germplasm Bank of the Federal University of Sergipe (UFS) located at the Experimental Farm "Rural Campus of the UFS," which have varied chemical composition. For this A549 cells (lung carcinoma) were treated with increasing concentrations (20-160 / mL) essential oils Lippia gracilis (genotypes 106 and 110) of Lippia alba (genotypes 13:57) and Lippia sidoides (genotypes 102 and 104) during the 24 hour interval. Cytotoxicity of these essential oils was determined by the MTT colorimetric method. The absorbance values obtained in the treatments were normalized to the untreated cells and used to calculate IC50 values by regression analysis. IC50 values of 75.42 and 158.6 ug / ml were obtained for the LG-106 and LG-110 genotypes, respectively. For LS-102 and LS-104 genotypes IC50 were respectively 97.93 and 150.70 mg / mL and LA-13 and LA-57 genotypes these values were 86.14 and 70.34 mg / mL . Microscopic analysis of cells stained by hematoxylin-eosin showed morphological changes, including condensation of cytoplasm, chromatin condensation and nuclear fragmentation induced by all genotypes. These results suggest that the cytotoxic activity presented by the essential oils of Lippia on A549 lineage cells involves induction of programmed cell death. Therefore, it is concluded that these oils represent a promising source compounds for the development of new anti-tumor therapies. / Os carcinomas de pulmão destacam-se como um grave problema de saúde pública, pois, encontram-se entre as principais causas de morte por câncer no mundo. São classificados em dois principais grupos histológicos: carcinoma de pulmão de células pequenas (CPCP) e carcinoma de pulmão de células não pequenas (CPCNP). Na busca por terapias inovadoras, diversos produtos naturais derivados de plantas e outros organismos têm sido estudados para utilização como fonte para o desenvolvimento de quimioterápicos empregados no tratamento de diversos tipos de câncer, inclusive dos carcinomas de pulmão. Nesse contexto, insere-se os óleos essenciais produzidos por plantas medicinais como as do gênero Lippia que apresentam diversas propriedades terapêuticas, dentre elas, atividade antimicrobiana, antinflamatória e antiproliferativa. O presente trabalho propõe a investigação da atividade citotóxica dos óleos essenciais de diferentes espécies e genótipos de plantas do gênero Lippia. do Banco Ativo de Germoplasma da Universidade Federal de Sergipe (UFS), localizado na Fazenda Experimental “Campus Rural da UFS”, que apresentam variada composição química. Para isso as células A549 (Carcinoma de pulmão), foram tratadas com concentrações crescentes (20 a 160 μg/mL) de óleos essenciais de Lippia gracilis (genótipos 106 e 110), de Lippia alba (genótipos 13 e 57) e Lippia sidoides (genótipos 102 e 104) durante o intervalo de 24 horas. A citotoxicidade destes óleos essenciais foi determinada pelo método colorimétrico do MTT. Os valores das absorbâncias obtidas nos tratamentos foram normalizados com os das células não tratadas e utilizados para calcular os valores de IC por análise de regressão. Valores de IC50 de 75,42 e 158,6 μg/mL foram obtidos para os genótipos LG-106 e LG-110, respectivamente. Para os genótipos LS-102 e LS-104 as IC50 foram, respectivamente, 97,93 e 150,70 μg/mL e para os genótipos LA-13 e LA-57 estes valores foram 86,14 e 70,34 μg/mL. A análise microscópica das células coradas por hematoxilina-eosina revelou alterações morfológicas incluindo condensação do citoplasma, condensação da cromatina e a fragmentação nuclear induzidas por todos os genótipos avaliados. Estes resultados sugerem que atividade citotóxica apresentada pelos óleos essenciais de Lippia sobre células da linhagem A549 envolve a indução de morte celular programada. Com isso, conclui-se que tais óleos representam uma fonte promissora de compostos para o desenvolvimento de novas terapias antitumorais. / São Cristóvão, SE

Abstract Essay in Political Science, autumn 2010. ”ALBA – A regional integration project with good conditions?” Autor: Anna Sjögren. Course: Political Science, C-level, Tutor: Sten Berglund   An essential part of the political science research on regional integration has been about why states join economic unions and what forces drive the process of integration. This essay is a case study on the Latin American regional integration project called ALBA. The purpose is to, from the ideas of the swiss political scientist Walter Mattli, investigate if ALBA has the conditions to be a successful integration group. To reach the purpose two questions have been asked: 1) What does the demand for regional integration in Latin America looks like? 2) What does the supply of regional integration in Latin America looks like? My methodological approach has been to read scientific articles and news articles that deal with ALBA and to see what they say about the conditions that are crucial according to Mattli. The result shows that the market in the region is not so diversified but that the member states have been doing some trading with each other. A lot of the trade has involved oil and that has effected the cooperation. The global financial crisis has implyed challenges to ALBA, as the oil price has fallen. But it has also given the alliance more legitimacy when the economic system that ALBA criticize has showed its deficiencies. To become a long-term project ALBA should end its dependence on oil. In Hugo Chávez ALBA has a rather undisputed leader. That Cuba, since the start of ALBA, has changed its political leader can have a significance. Due to the political orientation of ALBA the deveopment in the member states is crucial for the future of the union. That Brazil has chosen not to be a member of ALBA has both advantages and disadvantages for the alliance. Chávez has avoided a putative struggle of power but ALBA would probably be stronger if the region's economic, demographic, and territorial giant was participating.

El presente trabajo está orientado a detectar los símbolos y metáforas ambivalentes en la obraLa Casa de Bernarda Alba de Federico García Lorca. Debido a que hay pocos estudiosdedicados al simbolismo de la frustración, se ha concentrado en analizar dicha temática. Paraanalizar el concepto de frustración, primero ha sido necesario comprender cómo eraconcebida la moral de la época en que se inscribe la obra. En segundo lugar, ha sidofundamental entender cómo surge la frustración en el ser humano. Atendiendo a estascuestiones se ha aplicado la teoría del formalismo iluminista y una visión freudiana sobre lasteorías del psiquismo. En base a estas nociones se detectaron cuatro símbolos ambivalentesque connotan sentimientos de frustración: el blanco, el olivo, la maroma y el mar. Estossímbolos antitéticos contienen una fuerza negativa que se impone a la fuerza positiva, lo cualtiene como resultado la frustración. Las fuerzas contradictorias están presentes durante laobra entera. Esta característica no solo se manifiesta a través de los tropos estudiados, sinoque también se detectó que a menudo las fuerzas antitéticas se hacen presentes enprotagonistas que forman grupos ambivalentes, donde cada personaje actúa como una fuerzaopuesta, lo cual lleva hacia una tensión permanente entre una persona positiva y otranegativa.

The diploma thesis “The assessment of the phytotoxicity of sludge from selected sewage treatment plants“ deals with the current situation of the sludge treatment and disposal and the assessment of phytotoxicity of sewage treatment sludge. The sewage treatment sludge comes into existence during the process of sewage treatment. Nowadays is sludge landfilling from the point of view of nature protection and according to the legislation on the last place in a way of handling. Additionally, the thesis pays attention to the legislation related to the sewage treatment sludge and also statistical data concerning the production and the way of handling of the sewage treatment sludge. The practical part of the diploma thesis is focused on the description of two sewage treatment plants, namely Třebíč and Náměšť nad Oslavou. Subsequently were made several laboratory experiments with the sewage treatment sludge samples from the mentioned sewage treatment plants. At the sewage treatment sludge samples were assessed the phytotoxicity level by the testing set Phytotoxkit. Specifically was determined an inhibitive/stimulative effect on the growth of the root. The testing plant was a white mustard (Sinapis alba L.).

This study addressed the development of natural regeneration of tree species over the period 2009-2016 in a temperate fir-beech old-growth forest left to a spontaneous development since 1930s. The research site was located in the strictly protected National Nature Reserve Salajka, lying in the Western Carpathians mountain range. Ungulate game browsing, establishment and mortality of natural regeneration as the main drivers of species coexistence were studied, using two alternative sampling methods, permanent network of 98 inventory plots regularly positioned across the whole forest reserve and transect with 54 transect plots. Beech was found to secure gradually absolute dominance over other tree species in natural regeneration. The growth of fir, maple and spruce was hindered by browsing since the individuals rarely exceeded the height of 0.5 m. Further, the resource concentration effect was found in fir as browsing was more intense under high conspecific densities. Establishment and mortality of fir and beech differed, suggesting the species-specific life-history strategies. The results demonstrated the importance of regular and inextensive establishment of fir and huge but relatively less frequent establishment of beech. Mortality overweighed establishment in both species, though fir ratio tended to be almost balanced. The height of natural regeneration was revealed to be the only good predictor of mortality. Browsing, establishment and mortality of natural regeneration comprise an important part of forest regeneration processes and their role should be acknowledged by both forest and nature conservation management.
