Effets des extraits de compost (EC) fortifiés sur la croissance du soya (Glycine max (L.) Merr.)

Biron, François 16 April 2018 (has links)
En agriculture biologique, peu de produits sont autorisés pour améliorer la croissance des plantes. Cette étude qualifie les éléments solubles d’extraits de compost (EC) sur la croissance du soya. En présence ou non d’aération, six composts ont macéré dans l’eau pendant 14 jours et caractérisé. Quatre EC ont été sélectionnés, fortifiés et vaporisés sur le feuillage du soya cultivé dans du sable et traité avec de l’eau ou une solution nutritive. Les éléments solubles des EC évoluent en fonction du temps, dont les nitrates qui diminuent en fonction de l’aération. La teneur en éléments minéraux des EC est optimale après 2 jours et sans aération. L’EC «Fumier de vers» a démontré une augmentation du développement, des biomasses, et du prélèvement en éléments minéraux du soya traité avec une solution nutritive. L’effet bénéfique de cet EC semble lié à des substances de croissance solubles, autres que les éléments minéraux solubles. / In organic agriculture, there are few certified products that can be used to favor plant growth. This study was conducted to determine the soluble compounds from water extract of compost (WEC) that could benefit soybean growth. In the presence or the absence of aeration, six composts were macerated into water up to 14 days. Following the characterization of WEC, four were selected, enriched and applied on foliage of soybean grown in sand and watered with a nutrient solution or water. Over time, most soluble mineral salts went into solution, but N could be lost trough denitrification. To enhance mineral contents and minimize N loss, WEC should be produced within two days. When treated with the nutrient solution, the water extract of vermicompost enhanced soybean development, biomasses, and plant mineral contents. This WEC appears to favor plant growth through the provision of soluble growth substances, other than soluble mineral elements.

Le déséquilibre de liaison chez l'orge (Hordeum vulgare L.) : une fenêtre d'observation sur les effets de la sélection

Gauthier, Mélanie 16 April 2018 (has links)
L'analyse de 169 lignées canadiennes d'orge avec 883 marqueurs DArT a permis de mettre en évidence 15 régions génomiques qui affichent un déséquilibre de liaison (DL) avec le gène Vrsl. Dans un premier volet, 13 des 15 régions en DL ont été testées à l'aide de marqueurs SSR afin de vérifier si l'une des régions détermine la densité des épis, un caractère co-sélectionné avec le gène Vrsl. Aucun des marqueurs n'a présenté une association avec la densité de l'épi. Dans un second volet, nous avons tenté de déterminer l'emplacement chromosomique du gène DEP1, un gène récemment clone chez l'orge et soupçonné de contribuer au contrôle génétique de la densité de l'épi. Les produits d'amplification des quatre introns du gène DEP1 ont été séquences et comparés entre deux cultivars d'orge afin de découvrir des polymorphismes mononucléotidiques. Une absence totale de polymorphismes entre ces cultivars a rendu impossible la cartographie du gène DEP1 chez l'orge.

Caractérisation des signaux initiateurs de stress chez le fruit de la tomate suite à un stress oxydatif (UV-C) lors de la conservation

Guével, Marc-Henri 16 April 2018 (has links)
Chez les fruits et légumes, les techniques de conservation post-récolte visent à prolonger leur durée de vie, augmenter leur résistance aux maladies et éventuellement améliorer leur potentiel d'aliment fonctionnel. Ds réagissent comme des êtres vivants aux stress environnementaux. Ces stress, souvent délétères, peuvent engendrer des effets bénéfiques à faibles doses, phénomène biologique nommé hormèse. Une meilleure compréhension de la physiologie des fruits et légumes après un stress permettrait d'assurer un meilleur contrôle de leur métabolisme et améliorerait leur durée de conservation. Cette étude porte sur l'évolution d'indicateurs de stress (pertes ionique et pH tissulaire) et de molécules-signal (H2O2 et ethylene) du métabolisme de la tomate suite à un stress oxydatif (UV-C). Nos résultats, combinés à ceux d'autres études tendent à montrer que seulement l'analyse des signaux initiateurs pourrait suffire à déterminer la dose hormétique d'un stress. Ces doses pourraient ainsi être utilisées comme traitements post-récolte, et contribuer à une meilleure conservation des fruits et légumes durant l'entreposage.

Mezinárodní trestní soud a jeho věcná jurisdikce - se zaměřením na zločin agrese / The International Criminal Court and its subject-matter jurisdiction with regard to the crime of aggression

Kolářová, Michaela January 2011 (has links)
1 SUMMARY THE INTERNATIONAL CRIMINAL COURT AND ITS SUBJECT-MATTER JURISDICTION WITH REGARD TO THE CRIME OF AGGRESSION The current course of events concerning the crime of aggression and the search for its definition has undergone a remarkable shift during these days. In the light of the Revision Conference in Kampala, Uganda, whose declared aim was to evaluate the role and the up- to-date operation of the International Criminal Court as well as to find the definition of the crime of aggression and to set up the conditions to exercise the jurisdiction concerning the crime of aggression, the worldwide understanding of the conception of the crime of aggression has been significantly changed . The aim of this paper is to familiarize the reader with the problems regarding the crime of aggression, to describe the evolution of its conception in the field of international law within the last few decades and to provide the reader with a brief outline of some problematic questions which arose from the negotiations of the definition among the states. Further, the thesis attempts to depict the development of the negotiations themselves and to focus on the main disagreements, which the states had to face. The introductory chapter deals with some theoretical questions related to the international criminal justice. The...

JAG - Vem är det? : En studie om bilden av identitetssökandet hos unga flickor och pojkar i 2010 års barn- och ungdomslitteratur

Tengvall, Catrin January 2011 (has links)
Last spring I did a study where I studied how young girls where being depicted in Swedish novels of 2010. My ambition with this exam is to study how young teenage boys are being depicted in Swedish novels of 2010 and to compare this study and the results with the results from my study last spring. Throughout history we can see that boy’s novels have had the purpose to bring up boys into being adventurous. In the novels of 2010 we can see that boys now are being depicted in another more modern and contemporary way. From my analysis we can see that all the books have many things in common. One of them is the young boys search for identity and for finding who they really are. They all are struggling with their trust to themselves and their self-confidence. We can see that all the books show how young boys today are struggling to find the courage to stand up for themselves and their identity. In my comparison with the results of both of my studies we can see many similarities. Both studies shows young teenagers search for identity and for finding the courage to show how they really are and for standing up for themselves. We can that despite gender the young teenagers are all having the same reflections and feelings.

Estudo para a regionalização do gerenciamento de resíduos sólidos no Estado do Rio de Janeiro / Study for the regionalization of solid waste management in the State of Rio de Janeiro

Camila Spinola Gonçalves Ferreira 19 December 2011 (has links)
Impulsionados pela Lei 12.305/2010, que instituiu a Política Nacional de Resíduos Sólidos (PNRS), os estados brasileiros estão tentando viabilizar, especialmente com foco na destinação dos Resíduos Sólidos Urbanos (RSU), soluções consorciadas, visto que os resultados ambientais em termos de gerenciamento de resíduos sólidos, alcançados nos esforços individuais dos municípios, estão muito longe dos patamares aceitáveis. Sendo assim, o Estado do Rio de Janeiro, assim como demais estados brasileiros, para atendimento a nova PNRS precisará erradicar os lixões até o ano de 2014. Este trabalho tem por objetivo principal avaliar e analisar a viabilidade da estratégia do Ministério do Meio Ambiente (MMA), contemplada na PNRS, que indica a formação de consórcios entre os municípios para um melhor gerenciamento dos RSU, especialmente no que tange à sua destinação final, visando a confirmar a pertinência da escolha ou visualizar outras alternativas, em termos conceituais. Os resultados obtidos nesta pesquisa mostram que é indiscutível a contribuição de uma gestão regionalizada do RSU, através da formação de soluções consorciadas, observados no estudo de caso do Consórcio Costa Verde. Um grande desafio encontrado é o equacionamento de conflitos de interesses, em prol de um melhor gerenciamento dos resíduos, atenuando as divergências político-partidárias para que as tomadas de decisões sejam baseadas, sobretudo nas questões técnicas e administrativas, estabelecendo a melhor forma de proteger o meio ambiente / Driven by Law 12.305/2010, which established the National Policy on Solid Waste (PNRS - Política Nacional de Resíduos Sólidos), the Brazilian states are trying to enable, especially focusing on the disposal of urban solid waste (RSU Resíduos Sólidos Urbanos), consorted solutions, as the environmental results in terms of solid waste management, achieved in our individual municipalities, are far from acceptable levels. Therefore, the State of Rio de Janeiro, as well as other Brazilian states, in order to meet the new PNRS, need to eradicate the dumping by the year 2014. This study aims at assessing and analyzing the feasibility of the strategy of the Ministry of Environment (MMA - Ministério do Meio Ambiente), included in the PNRS, which indicates the formation of consortia of municipalities to better management of RSU, especially when it comes to its final destination in order to confirm the suitability or to analyze other alternatives, in conceptual terms. The results obtained in this study show that the contribution of a regionalized RSU management through the formation of consorted solutions, observed in the case study of the Consortium Costa Verde, is unquestionable. A major challenge faced is the solving of conflicts of interests, towards a better management of waste, softening the party and political differences so that the decision-making is based, mainly, on technical and administrative issues, establishing the best way to protect the environment
