Rabi Jehuda Liva ben Becal'el a kniha Zohar / Rabbi Judah Loew ben Bezalel and the Zohar

Kohoutová, Kamila January 2019 (has links)
This thesis deals with the intellectual heritage of Rabbi Judah Loew ben Bezalel, the Maharal of Prague and with his affiliation to the Kabbalah. The Kabbalah sprang up amongst Jewish scholars of 12th century Spain and reached its apex in the composition of the Zohar. This study shows the ways the Maharal used the Zohar and to what end. First chapter deals with the life and writings of the Maharal. The second summarises previous attempts to describe the Maharal's affinity for Jewish mysticism. The third chapter describes how the Zohar was written. It includes a textological comparison, which aims to find which edition or group of manuscripts of the Zohar the Maharal used. It also makes note of the special form of zoharic Aramaic that is present in the Maharal's writings. The fourth chapter raises the question of halakhic authority of the Zohar in the 15th and 16th centuries. Three main chapters of this thesis provide analysis and commentary of chosen zoharic texts (Zohar III,152a, Zohar III,40a, Zohar I,18a a Zohar I,33b) quoted by the Maharal in his writings and with their theological reflection. Zohar III,152a speaks about different layers of meaning implied in the text of the Torah. This chapter deals with the basic development of Jewish hermeneutics and attempts to find Maharal's place in it....

Construção de um sistema experimental para desaceleração de átomos. / Construction of an experimental system for stopping atoms.

Firmino, Marcel Eduardo 21 March 1991 (has links)
Neste trabalho apresentamos a construção e teste de um sistema experimental que nos permite produzir um fluxo intenso de átomos lentos. Discutimos o desenho e construção do solenóide que compensa o efeito Doppler que surge durante o processo de desaceleração, as câmaras de vácuo, o forno que gera o feixe atômico e o sistema ótico utilizado. Estudamos a técnica de desaceleração de átomos pelo ajuste Zeeman. Uma nova técnica de observação que consiste no acompanhamento da fluorescência do feixe ao longo do caminho de desaceleração é usada, o que nos permite uma observação direta do processo. / This work presents the development and test of an experimental set-up which allows to produce a very strong slow motion atomic beam. We discuss the calculation and construction of the solenoid to compensate the Doppler effect arising during the deceleration process, vacuum chambers, the oven which produces the atomic beam and the optical system used. We have studied the Zeeman-tuned technique to slow an atomic beam of sodium atoms. A new technique to study the deceleration which Consist in monitoring the fluorescence along the deceleration path is used, which allow us a direct observation of the process.

CONTROLE DE LA PROPAGATION D'IMPULSIONS ULTRACOURTES. EFFETS DE DELACEMENTS LUMINEUX

Delagnes, Jean-Christophe 15 December 2005 (has links) (PDF)
Cette thèse présente l'étude théorique et expérimentale du contrôle<br />des phénomènes de propagation cohérente d'impulsions ultracourtes<br />dans un milieu résonant optiquement dense. Dans une première partie,<br />nous décrivons les phénomènes élémentaires des effets de<br />propagation. L'épaisseur optique caractérise l'importance de la<br />distorsion temporelle qui apparaît en général sur l'impulsion. A<br />l'image des compensateurs à prismes ou à réseaux utilisés pour<br />compenser la dispersion d'un milieu transparent, on montre que cette<br />dispersion résonante peut être compensée par l'utilisation d'un<br />façonneur d'impulsion haute résolution. Dans un second temps, nous<br />développons l'idée de contrôler par un champ fort, les propriétés<br />transitoires d'une autre impulsion faible et résonante qui se<br />propage simultanément dans le milieu. Le champ fort induit des<br />modifications transitoires dans le milieu, qui se répercutent et<br />modifient par rayonnement le champ de l'impulsion résonante qui se<br />propage. Dans un système à trois niveaux en échelle, des modulations<br />visibles sur le profil temporel, révèlent les déplacements lumineux<br />induits de manière non résonante sur les deux états excités. Leur<br />durée caractéristique est plus courte que celle de l'impulsion<br />initiale : il y a un enrichissement du spectre transmis. Ces<br />oscillations résultent du battement entre le champ incident et le<br />champ rayonné dont la fréquence varie sous l'effet des déplacements<br />lumineux. L'excitation "bichromatique" d'un système à deux niveaux,<br />présente deux configurations géométriques qui donnent accès à des<br />informations différentes. En plus des phénomènes précédents qui<br />apparaissent en configuration non colinéaire, les effets des<br />transitions non adiabatiques induites par le champ de contrôle se<br />manifestent également dans le cas colinéaire. Le champ faible est<br />alors une sonde particulièrement sensible à ces effets. Nous<br />étudions enfin une configuration où les deux impulsions, polarisées<br />orthogonalement, excitent de manière résonante un système à quatre<br />niveaux dégénérés deux à deux. Puisque le champ fort mélange les<br />états, les chemins d'émission et d'absorption du champ faible ont<br />des poids équivalents. Ces deux chemins interfèrent modulant ainsi<br />l'énergie de l'impulsion transmise. La combinaison des déplacements<br />lumineux et de ces interférences, permet de contrôler aussi bien le<br />gain que la forme temporelle de l'impulsion.

Židovské znovuosídlení Hebronu po roce 1967 / Jewish Resettlement of Hebron after 1967

Hosnédlová, Eva January 2015 (has links)
The thesis outlined the history of the Jewish settlement of Hebron from Biblical times to the year 1929, which was the milestone in the history of the Jewish settlement of this city. The thesis describes the aftermath of the Six-Day War (in June 1967) and the atmosphere in the Jewish society, which played into the hands of the spiritual authorities of religious Zionism - e.g. Abraham Isaac Kook and his son Tzvi Yehuda Kook. Their messianic expectations and teachings, which made the settlement of the Land of Israel the top priority, led to the expansion of the settlement in the territory of biblical Judea and the Samaria Area. We watched the beginning of settlement activities that significantly affected politics. We provided examples that led to the "resettlement" of Hebron after 1979 when the women and children of the settlers from Kirjath Arba occupied the former Jewish hospital Hadassa, which meant the actual "resettlement" of Hebron because up until then, their settlements had been built only on the outskirts of the city. I also tried to describe the settlement differences and motivations between both Jewish communities before and after the Six-Day War.
