The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.

In this paper, by employing the threshold regression method, we estimate the average tariff equivalent of fixed costs for the use of a free trade agreement (FTA) among all existing FTAs in the world. It is estimated to be 3.2%. This global estimate serves as a reference rate in the evaluation of each FTA’s fixed costs.

The aim of the present work is to provide an in-depth analysis of the most representative mirroring techniques used in SPH to enforce boundary conditions (BC) along solid profiles. We specifically refer to dummy particles, ghost particles, and Takeda et al. [Prog. Theor. Phys. 92 (1994), 939] boundary integrals. The analysis has been carried out by studying the convergence of the first- and second-order differential operators as the smoothing length (that is, the characteristic length on which relies the SPH interpolation) decreases. These differential operators are of fundamental importance for the computation of the viscous drag and the viscous/diffusive terms in the momentum and energy equations. It has been proved that close to the boundaries some of the mirroring techniques leads to intrinsic inaccuracies in the convergence of the differential operators. A consistent formulation has been derived starting from Takeda et al. boundary integrals (see the above reference). This original formulation allows implementing no-slip boundary conditions consistently in many practical applications as viscous flows and diffusion problems.

No romance O Idiota, Dostoiévski cria, por meio do príncipe Míchkin, uma personagem com as características do Cristo. Sabe-se que a Bíblia, principalmente o Novo Testamento, acompanhou o escritor desde sua infância até o momento de sua morte. O primeiro capítulo, dedicado ao referencial teórico da pesquisa, lida com o universo da linguagem. Tanto o texto literário quanto a literatura bíblica procedem do mito. Neste sen-tido, religião e literatura se tocam e se aproximam. O segundo capítulo foi escrito na intenção de mostrar como o Cristo e os Evangelhos são temas, motivos e imagens recorrentes na obra de Dostoiévski. A literatura bíblica está presente, com mais ou menos intensidade, em diversas das principais obras do escritor russo e não somente em O Idiota. A hipótese de que Dostoiévski cria um Cristo e um Evangelho por meio de O Idiota é demonstrada na análise do romance, no terceiro capítulo. A tese proposta é: Dostoiévski desenvolve um evangelho literário, por meio de Míchkin, misto de um Cristo russo, ao mesmo tempo divino e humano, mas também idiota e quixotesco. Na dinâmica intertextual entre os Evangelhos bíblicos e O Idiota, entre Cristo e Míchkin, a literatura e o sagrado se revelam, como uma presença divina. Nas cenas e na estruturação do enredo que compõe o romance, Cristo se manifesta nas ações de Míchkin, na luz, na beleza, mas também na tragicidade de uma trajetória deslocada e antinômica. O amor e a compaixão ganham forma e vida na presen-ça do príncipe, vazio de si, servo de todos.

Ambivalent Sovereignty inquires into the subject of political realism. This subject, sovereign authority, appears to have a dual foundation. It appears divided against itself, but how can realism nonetheless observe legitimate modes of sovereignty emerge? Against the liberal idea that a "synthesis" of both material-coercive and ideal-persuasive powers should be accomplished, within the world of international relations, realism gives meaning to a structural type of state power that is also constitutionally and legitimately dividing itself--against itself. Machiavelli but particularly also other realists such as Hannah Arendt, Max Weber, and Aristotle are being reinterpreted to demonstrate why each state's ultimate authority may symbiotically emerge from its self-divisions, rather than from one synthetic unity. Whereas liberal theorists, from Montesquieu to John Rawls and Alexander Wendt, err too far in assuming the presence of the state's monistic authority, the realist theorists further advance an answer to how sovereign states may begin to both recognize and include only the most-legitimate manifestations of their common dualist authority. Ambivalent Sovereignty is relevant in this sense as it transcends-and-yet-includes these common dualities: freedom/necessity; emergence/causation; self-organization/power structures.
