Les informations relatives aux cryptomonnaies sont susceptibles de changer à l'avenir tant cette matière est nouvelle et encore peu ancrée dans le droit. Ce mémoire est une réflexion sur l'essor du Bitcoin et des cryptomonnaies à leurs débuts, alors même que le droit cherche à s'accaparer ces nouvelles technologies, à les intégrer dans son système préexistant.

Even though the economic crisis proved harmful to the Russian economy and people's living standards, it has nonetheless failed to make the elite revise its policy. Despite some problems, the government has managed to sustain economic and political stability, thanks to the reserves it amassed in the times of prosperity, and to the propaganda campaign that protected it, above all Vladimir Putin. The crisis failed to force the elite to implement deeper structural and political reforms. Moreover, it has actually reinforced existing tendencies, such as state control over the economy and its oil-oriented character, the elite's economic expansion at the expense of private businesses, and the preservation of political power. Thus, the crisis has so far failed to dismantle Putinism, indeed quite the reverse - it has in fact contributed to its becoming 'set in stone'.

Many European and American observers of the EC have criticized "intergovemmentalist" ac­ counts for exaggerating the extent of member state control over the process of European integra­ tion. This essay seeks to ground these criticisms in a "historical institutionalist" account that stresses the need to study European integration as a political process which unfolds over time. Such a perspective highlights the limits of member-state control over long-term institutional de­ velopment, due to preoccupation with shorHerm concerns, the ubiquity of unintended conse­ quences, and processes that "lock in" past decusions and make reassertions of member-state control difficult. Brief examination of the evolution of social policy in the EC suggests the limita­ tions of treating the EC as an international regime facilitating collective action among essentially sovereign states. It is ore useful to view integration as a "path-dependent" process that has pro­ duced a fragmented but still discernible "multitiered" European polity.

Growth of complexity and functional importance of integrated navigation systems (INS) leads to high losses at the equipment refusals. The paper is devoted to the INS diagnosis system development, allowing identifying the cause of malfunction. The proposed solutions permit taking into account any changes in sensors dynamic and accuracy characteristics by means of the appropriate error models coefficients. Under actual conditions of INS operation, the determination of current values of the sensor models and estimation filter parameters rely on identification procedures. The results of full-scale experiments are given, which corroborate the expediency of INS error models parametric identification in bench test process.

Tobacco was of primary importance to Spain, and its impact on Cuba's economy and society was greater than just the numbers of farms, workers, or production, demonstrated by the Spanish crown's outlay of monies for capital assets, bureaucrats' salaries, and payments to farmers for their crop. This study is a micro- and macro-level study of rural life in colonial Cuba and the interconnected relationships among society, agricultural production, state control, and the island's economic development. ^ By placing Cuba's tobacco farmers at the forefront of this social history, this work revisits and offers alternatives to two prevailing historiographical views of rural Cuba from 1763 (the year Havana returned to Spanish control following the Seven Years' War) to 1817 (the final year of the 100-year royal monopoly on Cuban tobacco). Firstly, it argues against the primacy of sugar over other agricultural crops, a view that has shaped decades of scholarship, and challenges the thesis which maintains the Cuban tobacco farmer was almost exclusively poor, white, and employed free labor, rather than slaves, in the production of their crop. ^ This study establishes the importance of tobacco as an agricultural product, and argues that Cuban tobacco growers were a heterogeneous group, revealing the role that its cultivation may have played in helping some slaves earn their freedom. ^

Communication technologies shape how political activist networks are produced and maintain themselves. In Cuba, despite ideologically and physically oppressive practices by the state, a severe lack of Internet access, and extensive government surveillance, a small network of bloggers and cyberactivists has achieved international visibility and recognition for its critiques of the Cuban government. This qualitative study examines the blogger collective known as Voces Cubanas in Havana, Cuba in 2012, advancing a new approach to the study of transnational activism and the role of technology in the construction of political narrative. Voces Cubanas is analyzed as a network of connections between human and non-human actors that produces and sustains powerful political alliances. Voces Cubanas and its allies work collectively to co-produce contentious political discourses, confronting the dominant ideologies and knowledges produced by the Cuban state. Transnational alliances, the act of translation, and a host of unexpected and improvised technologies play central roles in the production of these narratives, indicating new breed of cyborg sociopolitical action reliant upon fluid and flexible networks and the act of writing.

In dem vorliegenden Beitrag werden neuere schulgesetzliche Initiativen erörtert, die u.a. eine Reform des Übertritts aus der Grundschule an weiterführende Schulen beabsichtigen. Diese Bemühungen ordnen sich in die schon lange zu beobachtende Tendenz zur Stärkung der individuellen Rechte von Schülern und Eltern ein, wie sie mit dem Prozeß der Verrechtlichung der Schule in der Bundesrepublik verbunden ist. Eine genauere Betrachtung der entsprechenden Regelungen und einiger dadurch ausgelöster gerichtlicher Konflikte weckt allerdings Zweifel an Voraussetzungen und insbesondere an Ergebnissen der eingeleiteten Politik: Handelt es sich nicht doch um eine versteckte Form der staatlichen Steuerung der Schulwahl?

Resumen: Los materiales basados en cementos presentan una enorme importancia tecnológica. Para una correcta utilización es necesario que sea posible su transporte y conformado en un estado “fresco”, por lo que es fundamental controlar su comportamiento reológico. En esta conferencia se describe el comportamiento reológico de morteros y productos relacionados, en situaciones prácticas, donde se tratarán casos concretos, y se discutirán las principales características de cada comportamiento. Además, se presentarán los nexos de unión entre la reología y la tecnología de los materiales de la construcción. Abstract: Cement-based materials are of enormous technological importance and their satisfactory performance depends on being able to transport and mould them in the freshly mixed state. This conference describes the rheology of mortars and related products in the context of practical situations, and deals with testing and measurement, together with the main features of their behaviour. It explores the links between rheology and technology.

Este artigo condensa um conjunto de reflexões baseadas em factos relacionados com a gestão da qualidade nas Instituições de Ensino Superior (IES). São identificados factores internos e externos favoráveis à melhoria da qualidade dos serviços prestados por estas organizações, bem como algumas das barreiras que se lhe opõem. Relativamente às abordagens da qualidade, nestas organizações são consideradas: de um lado as que resultam da Supervisão do Estado e do outro as que estão associadas a sistemas de natureza voluntária, designadas aqui por Abordagem Qualidade, em que sobressai a Certificação baseada na norma ISO 9001 e os sistemas de Gestão pela Qualidade Total (GQT) também designados de Excelência Organizacional. São identificadas algumas das insuficiências dos modelos assentes na Supervisão do Estado e defendida a importância de atender ao conjunto de “boas práticas” já existentes, ao invés de abordagens que tratam desta problemática numa perspectiva ab initio, sem contemplar o conhecimento acumulado neste domínio da gestão das organizações.

We investigate the reaction dynamics of diffusive molecules with immobile binding partners. The fixed reactants build clusters that comprise just a few tens of molecules, which leads to small cluster sizes. These molecules participate in the reaction only if they are activated. The dynamics of activation is mapped to a time-dependent size of an active region within the cluster. We focus on the deterministic description of the dynamics of a single cluster. The spatial setup accounts for one of the most important determinants of the dynamics of a cluster, i.e. diffusional transport of reaction partners toward or away from the active region of the cluster. We provide numerical and analytical evidence that diffusion influences decisively the dynamic regimes of the reactions. The application of our methods to intracellular Ca²⁺ dynamics shows that large local concentrations saturate the Ca²⁺ feedback to the channel state control. That eliminates oscillations depending on this feedback.

Es ist ein lang gehegter Traum in der Chemie, den Ablauf einer chemischen Reaktion zu kontrollieren und das Aufbrechen und Bilden chemischer Bindungen zu steuern. Diesem Ziel verschreibt sich auch das Forschungsgebiet der Femtochemie. Hier werden Femtosekunden Laserpulse eingesetzt um auf dem Quantenlevel molekulare Dynamiken auf ihren intrinsischen Zeitskalen zu kontrollieren und das System selektiv und effizient von einem Anfangs- in einen Zielzustand zu überführen. Der Wunsch, mit geformten Femtosekunden Laserpulsen Kontrolle über transiente Dynamiken und finale Populationen auszuüben, zu beobachten und zu verstehen, bildet auch die Motivation für diese Arbeit. Hierzu wurden mit Hilfe der Photoelektronenspektroskopie Untersuchungen zur Wechselwirkung atomarer und molekularer Prototypsysteme mit intensiven, geformten Femtosekunden Laserpulsen durchgeführt. Die Verwendung von Modelsystemen ermöglicht es, grundlegende Mechanismen der kohärenten Kontrolle in intensiven Laserfeldern zu analysieren, ohne dass sie durch komplexe Wechselwirkungen verschleiert werden. Zunächst wurde die Wechselwirkung von Kaliumatomen mit gechirpten Femtosekunden Laserpulsen untersucht. In den Experimenten wurden sowohl transiente Dynamiken als auch die Endbesetzungen der elektronischen Zustände abgebildet. In den folgenden Experimenten wurde das Quantenkontrollszenario SPODS auf die gekoppelte Elektronen-Kern-Dynamik in Molekülen übertragen. Die Kontrolle basiert auf der Erzeugung und Manipulation von Ladungsoszillationen durch Pulssequenzen. Der letzte Teil widmet sich der Entwicklung adiabatischer Kontrollmechanismen in Molekülen. Bei den Experimenten wurden gechirpte Airypulse eingesetzt um robuste Starkfeldanregung in molekularen Systemen zu induzieren. In Zukunft wird die Erforschung immer komplexerer Moleküle im Rahmen der transienten Kontrolle im Fokus stehen. Dabei werden nicht nur die effiziente Besetzung gebundener Zustände von Interesse sein, sondern auch die gezielte Dissoziation in spezifische Fragmente, photoinduzierte Isomerisierungsreaktionen oder die Kontrolle über transiente Dynamiken, die Einfluss auf andere molekulare Eigenschaften haben. Vor dem Hintergrund dieses übergeordneten Wunsches, photochemische Reaktionen immer komplexerer Moleküle, bis hin zu großen, biologisch relevanten Molekülen, zu kontrollieren, ist es umso wichtiger, die zugrundeliegenden Anregungsmechanismen in einfachen Systemen nachzuvollziehen. In den hier präsentierten Experimenten wurde gezeigt, wie die simultane Beobachtung der bekleideten und der stationären Zustände in atomaren Systemen zu einem umfassenden Bild der lichtinduzierte Dynamiken führen kann. Die gewonnenen Erkenntnisse können auf die Steuerung gekoppelter Dynamiken übertragen werden, durch die Kontrolle auch in molekularen Systemen möglich wird.
