We are interested in finding conditions which guarantee the existence of p-adic zeros to the pair (2). A well-known conjecture due to Emil Artin states that the condition n > 2k2 is sufficient. By means of techniques of Combinatorial Number Theory, we prove that n > 2 p (p/ P – 1) k2 − 2k is sufficient if k = 2.3Τ ou 4.5Τ, and in any case if Τ≥ (p – 1)/ 2.

This master’s thesis is made to increase the understanding of the dynamic characteristics of a typical large swing check valve used in a system that transports pressurized water to a reactor tank.3D FSI-simulations are performed for a number of transients in order to study the dynamic characteristics their dependence of the deceleration rate. The purpose is to find information about the dynamics that could be used in a future improvement of a 1D-model.Steady state simulations are performed for angles in the whole spectrum. Seven transient FSI-simulations with different constantly decelerating flows from 630 kg/s2 (6.7 m/s2) to 40 320 kg/s2 (430 m/s2) have been performed. The pressure on the disc caused by the hydraulic torque is integrated and the corresponding torque contribution, together with the weight torque, is used in the second law of motion to calculate the movement of the disc throughout the transients.Steady state simulations yield the pressure drop over the valve, which could be compared with field measurements in order to validate the CFD-simulations. Comparison of the pressure distribution on the disc for the steady state and transient simulations shows the importance of taking the disc angular velocity into account when modelling in 1D. Correlations between the angle, angular velocity, torque and mass flow are obtained from the transient FSI-simulations. Torque coefficients according to (Li & Liou, Vol. 125) are also brought out from the simulated transients, but in order to create a model in line with this approach further simulations have to be performed. A prediction of the pressure rise that occurs when a swing check valve closes in backward flow according to the Joukowsky equation is brought out and gives an idea of the loadings that the system has to be able to handle.

It looks as though the larger the concentration of people, the greater the globalization of the world advances, the louder this cry for help is heard. This cry for a meaningful life is present both in the young as well as in older adults in all social classes. The world has lived through transformations and an existential vacuum is visible in the individual of today s society; the sensation of the lack of meaning, an interior emptiness. Beginning with this observation, this research has as its objective to demonstrate that it is possible to find meaning to life, having as a fundamental presupposition the discovery of the meaning of life by each person and the use of the cognitive power of the individual mind. It is only through this presupposition that it is possible to understand the reason why Frankl dedicated himself to the topic of the meaning of life emphasizing the role of faith, religiosity and logotherapy as the answer for the question about the meaning [of life] that has as its objective to widen the horizon of the human being, thus showing that, to all who can still be enthusiastic about something, there could still be much to do a significant number of tasks awaits them. Therefore, there is enough meaning. / O pensamento de Viktor Emil Frankl quanto ao sentido da vida é relevante e atual, porque existe um clamor universal por esse sentido, que é escutado principalmente nas áreas urbanas onde estão concentradas as grandes massas. Parece que quanto mais a população se aglomera, quanto maior a globalização mundial avança, mais este grito por socorro é escutado. Esse grito por um sentido para vida está presente desde os mais jovens até os mais velhos e em todas as classes sociais. O mundo tem passado por transformações e nota-se nos indivíduos da sociedade contemporânea a presença de um vácuo existencial ; a sensação de falta de sentido, de vazio interior. Partindo desta constatação, esta pesquisa objetivou demonstrar que é possível encontrar sentido para a vida, tendo como pressuposto fundamental a descoberta do sentido da vida por cada pessoa e o uso da força cognoscitiva da mente individual. É somente com este pressuposto que se compreende o motivo pelo qual Frankl se dedicou ao assunto sentido da vida destacando a fé, a religiosidade e a logoterapia como resposta para a questão do sentido que tem como finalidade abrir o horizonte do ser humano, mostrando a ele que, para todos aqueles que ainda conseguem se entusiasmar com alguma coisa, ainda haveria muito a fazer um número bastante grande de tarefas espera por eles. Portanto, há sentido suficiente.

This thesis deals with the question of reception of the work and the personality of Emil Hakl. It focuss on mapping of the acceptance of his books by literary criticism, it explores the way of writing about the author and his work. Considering that he is a contemporary author and his work is not yet reflected in a separate monograph, the material consists mainly of reviews in literary journals (Advojka, Český jazyk, Český jazyk a literatura, Host, Respekt, Tvar). The thesis is also devoted to the analysis of discourse. It asks questions on how is the critique of speech characterized, when it deals with the character of the contemporary writer.

En étudiant quatre aspects du temps (le temps historique, le temps mythique, le temps existentiel, et le temps eternel) chez l’essayiste et le philosophe roumain d’expression française, Emil Cioran (1911-1995) en m’appuyant sur les théories de Nietzsche, Bergson et Eliade, nous arrivons à la conclusion que la construction et la déconstruction des temps historique, mythique, existentiel et éternel traversent toutes les œuvres de mon corpus. Le je-cioranien ne s’intéresse ni à la durée, ni au temps, ni à l’éternité, ni à la vie. La vie en soi est détruite et méprisée et sa durée est déconstruite ; l’essayiste préfère au contraire la durée pure de l’instant, qui vaut « plus qu’une éternité » ; c’est dans l’instant qu’il trouve la temporalité bergsonienne et une éternité plus « positive ». L’histoire est également déconstruite et considérée comme un spectacle qui n’a ni but, ni sens. La seule dimension utilisée de manière positive et admirée par Cioran reste le mythe, dont les héros (Jésus, Bouddha, Prométhée) et les personnages mythologiques (Phénix, Sisyphe, Atlas, Ulysse) représentent les modèles à suivre dans la vie quotidienne. Le mythe sauve d’ailleurs l’humanité et son histoire. Le retour aux origines, même avant la naissance, est le grand but cioranien, le trajet à rebours de ce « héros négatif » (David, 2006 B : 253) par le biais duquel il voudrait rejoindre l’éternité mythique. La conscience du je-personnage est poussée (par le biais de la mémoire) dans le passé, en évoquant l’enfance (donc la vie) et ce retour suppose la décomposition de l’être, « un être éparpillé » (EC) dont le moi se décompose « en mille souvenirs », état d’âme qui caractérise la plupart de ses aphorismes. Ainsi, en ayant plutôt situé le passé dans le futur, l’être cioranien vacille, décomposé, malade avec de rares étincelles de lucidité. Cette thèse montre dans ses sept chapitres l’attachement cioranien au temps et en même temps son drame personnel, le fait que l’essayiste se situe « en dehors du temps », bien qu’il ne puisse vivre que « par le temps ». Cette existence « par le temps » suppose un double aspect : d’abord, c’est le temps qui représente le je-narrateur et il ne peut ni ne veut s’en débarrasser (comme la mère de ses enfants) et d’autre part il ne peut vivre que dans des parcelles de temporalité, comme si le temps était le labyrinthe où le narrateur se cacherait toujours. Cioran joue ainsi un rôle médiatique entre la conception du temps dans le monde ancien et le monde moderne, comme un acteur qui entre sur scène et répète sans cesse des fragments anciens de la pièce (sur son enfance et sur son passé) et qui regrette d’être obligé de sortir de la scène si vite et donc de ne pas rester jusqu'à la fin de la pièce. L’aphorisme, cette forme d’écriture fragmentaire, est aussi une manière formelle et philosophique par laquelle Cioran répond aux exigences du temps et sa décomposition de la vie : d’une manière facile (par la forme) mais philosophique et ironique (par son contenu).
