Implications surrounding body ownership prove to be an enduring struggle from their prevalence in ancient literary sources through more modern, contemporary works. I analyze the notions of body ownership and its lack thereof set forth in Ovid’s Metamorphoses and the Homeric “Hymn to Demeter” regarding the myth of Persephone. Then, I consider larger meanings through analysis of the following contemporary works, approached in terms of the narrators: Rita Dove’s Mother Love, Louise Glück’s Averno, A.E. Stallings’s “Hades Welcomes His Bride” and “Persephone Writes a Letter to Her Mother,” and D.M. Thomas’s “Pomegranate.” The complexities within the myth itself amplify the complications in the contemporary interpretations of the myth. There is a range of differing levels of accepting sentiments in the contemporary works about the idea that no one ever has complete ownership or control over his own body. Comparing the different lenses through with the contemporary authors (and ancient authors!) chose to incorporate the myth of Persephone into their works reveals overarching themes, enlightening the reader about the nuances of the arguably most famous abduction in history.

This diploma thesis deals with biodynamic agriculture in the Czech Republic. The theoretical part concerns the definition of organic and biodynamic farming, including the identification of their mutual differences, and also describes the development of biodynamics in the global and domestic context, including the analysis of the current state. The experimental part is made up of several outputs. The first is the characteristic of a selected biodynamic farm which includes a mapping of opinions about the farm activities among the locals. The second is the analysis of information from biodynamic farmers or otherwise interested parties about their experience and opinions on the given issue. The final output is the evaluation of the information obtained through the survey detecting the awareness about biodynamic farming among selected target groups.

La symbiose légumineuse/rhizobium résulte en la formation d’un nouvel organe racinaire, le nodule, au sein duquel une induction coordonnée et massive de milliers de gènes a lieu. Plusieurs gènes contrôlant la méthylation de l’ADN sont régulés de façon spatiale au sein des nodules de Medicago truncatula, dont notamment un gène codant pour une déméthylase, DEMETER (DME), fortement exprimé dans la zone de différenciation. Ici, nous montrons que MtDME est essentiel pour le développement du nodule et qu’il régule l’expression de 1425 gènes, dont certains essentiels pour la différenciation des cellules de plantes et des bactéries. Une approche de séquençage bisulfite couplée à une capture génomique nous a permis d’identifier 474 régions qui sont différentiellement méthylées au cours du développement nodulaire, comportant notamment des gènes codant pour des peptides NCRs (Nodule-specific Cysteine-Rich). La diminution de l’expression de MtDME par ARN interférant mène à l’hyperméthylation et à la down-régulation de 400 gènes, la plupart d’entre eux étant associés à la différenciation du nodule. Une reprogrammation massive de l’expression génique via la déméthylation de l’ADN représente donc un nouveau mécanisme épigénétique qui contrôle une étape clé de l’organogenèse des nodules indéterminés durant l’interaction symbiotique. / The legume-Rhizobium symbiosis leads to the formation a new organ, the root nodule, involving coordinated and massive induction of specific genes. Several genes controlling DNA methylation are spatially regulated within the Medicago truncatula nodule, with notably a demethylase gene, DEMETER (DME), mostly expressed in the differentiation zone. Here, we show that MtDME is essential for nodule development and regulates the expression of 1425 genes, certain critical for plant and bacterial cell differentiation. Bisulphite sequencing coupled to genomic capture enabled the identification of 474 regions that are differentially methylated during nodule development, including notably Nodule-specific Cysteine-Rich peptide genes. Decreasing DME expression by RNA interference led to hypermethylation and concomitant downregulation of 400 genes, most of them associated with nodule differentiation. Massive reprogramming of gene expression through DNA de-methylation is a new epigenetic mechanism controlling a key stage of indeterminate nodule organogenesis during symbiotic interactions.

O presente estudo, incluindo a tradução do texto grego, dedica-se à natureza e sentido da Mãe-Terra, mostrando que o Hino Homérico comemora o inviolável e eterno ser de Deméter e sua filha Perséfone, narrando a reação repulsiva da mãe diante da violência paterna que dá a filha deles como esposa ao rei do Hades, ignorando os laços consangüíneos que as unem. Irada, a Mãe-Terra age, pondo em risco a estabilidade cósmica até que, limitada por sua moîra coercitiva, encontra e propõe um acordo mediador, que põe fim ao conflito e leva seu poder a ascender na sagrada ordem do poder de Zeus pai. / The present study, including the translation of the Greek text, dedicates itself to the nature and sense of the Earth Mother, explaining that the Homeric Hymn commemorates the inviolable and eternal being of Demeter and her daughter Persephone, narrating the mother’s repulsive reaction before the paternal violence who gives their daughter as wife to the king of Hades, ignoring consanguineous laces that associate them. Angry, Earth Mother acts, putting in risc the cosmic stability until, limited by her coercive moîra, finds and proposes mediator accord, which ends the conflict and makes her power to ascend to the sacred order of the Zeus father’s power.

Electromagnetic waves are crucial for energy transfer in the nearly collision- less plasma of the Earth's inner magnetosphere. The waves in the frequency range 1-8 kHz whose visualisation in the form of frequency-time spectrograms reveals a harmonic frequency modulation of the wave intensity are called magnetospheric line radiation (MLR). Waves characterized by a nearly periodic time modulation of the wave intensity observed at frequencies between about 0.5 and 4 kHz are called quasiperiodic (QP) emissions. Although both types of the events were re- peatedly observed by ground-based instruments and low-altitude satellites, their origin remains still unclear. Between 2004 and 2010 these wave events were me- asured by the DEMETER spacecraft (almost Sun-synchronous orbit, altitude of about 700 km). This thesis presents a systematic study of the properties of the observed events, a comparison of the observations by the spacecraft and ground- based instruments, and an investigation of a relation to solar wind parameters.

Cette thèse présente des résultats basés sur les mesures d'ondes réalisées par le satellite DEMETER. Ce satellite français a été exploité entre les années 2004 et 2010 à l'altitude de ~660 km. Nous nous sommes concentrés sur les mesures des ondes électromagnétiques et de la densité du plasma au voisinage des tremblements de terre imminents .Dans la première partie, nous présentons une étude des variations de la densité du plasma dans le voisinage d'un tremblement de terre très puissant au Chili ( Mω 8.8) qui a eu lieu le 27 Février 2010. Les données enregistrées avant le choc principal le long des orbites proches de l'épicentre ont montré des augmentations de densité du plasma. Dans une deuxième étape, une analyse statistique a été effectuée en utilisant 4 ans de données pour suivre les variations saisonnières de densité. Cette étude montre qu'une augmentation forte de la densité du plasma est très rare dans cette région à l'époque du séisme. Dans la deuxième partie, une étude statistique (~6,5 ans) des variations de l'intensité des ondes TBF est montrée. Nous avons analysé toutes les données mesurées disponibles à proximité (en temps et en distance) de grands séismes (M> ou = 5). Les données relatives à plus de 12000 tremblements de terre ont été comparées avec une distribution de référence non perturbée. Nous confirmons les résultats déjà rapportés de la diminution statistiquement significative de l'intensité des ondes à des fréquences de l'ordre de ~1,7 kHz. Cet effet semble être lié à une diminution de la limite inférieure de l'ionosphére qui affecte les ondes TBF qui se propagent dans le guide Terre-ionosphère.
