Micro-Ceasefire Under Shadow

Journal of Physical Oceanography, 2008

A theory for the exchange between a rotating, buoyancy-forced marginal sea and an ocean is developed and tested numerically. Cooling over the marginal sea leads to sinking and sets up a two-layer exchange flow, with a warm surface layer entering from the ocean and a cool layer exiting at depth. The connecting strait is sufficiently narrow and shallow to cause the exchange flow to be hydraulically controlled. The incoming surface layer forms a baroclinically unstable boundary current that circles the marginal sea in a cyclonic sense and feeds heat to the interior by way of eddies. Consistent with the overall heat and volume balances for the marginal sea, there is a continuous family of hydraulically controlled states with critical flow at the most constricted section of the strait. Included in this family is a limiting "maximal-exchange" solution with two sections of hydraulic control in the strait and with fixed layer depths at the most constricted section. The state of exchange for a given forcing is predicted using a theory that assumes energy conservation over a certain path connecting the strait to the marginal sea or, in some cases, the ocean. Depending on the configuration of the exchange, long-wave information may be blocked from entering the strait from the marginal sea, from the open ocean, or both. The scenario that holds determines what is predicted and what needs to be input. Numerical tests of the prediction for the temperature difference and the state of exchange are carried out for straits with a pure contraction in width and for a constant width strait with a topographic sill. The comparison is reasonable in most cases, though the numerical model is not able to reproduce cases of multiple states predicted by the theory for certain forcing values. The analytical model is an alternative to the Price and Yang and Siddall et al. models of a marginal sea outflow.

This essay examines Bruno Munari’s innovative picture books within the broader context of his ‘major’ artistic work. Specifically, it illustrates and discusses how Munari’s production that is linked to Futurism, Abstractionism, or Concrete art, has been remediated in his books and activities for children. Munari’s work is on this score an unparalleled example of the ways the visual language of experimental art could be translated into effective and meaningful visual experiences for lay people, including children.

Mario Bunge encontramos 3 libros, en el mundo de la ficción construimos 3 platos voladores. ¿Pero quién vio jamás un 3, un simple 3?

Аннотация. Слово «эволюция» часто употребляют как термин свободного пользования либо без должного обоснования даже и в научной литературе (как модное украшение), что приводит к досадным недоразумениям. С научных позиций понятие «эволюция» в обобщённом виде означает необратимое и (в известной мере) направленное развитие. В силу всеобщей связи явлений Природы решение вопроса о движущих силах эволюции, их механизме следует искать в плоскости тесной взаимосвязи фундаментальных отношений единства в ряду «Земля -Солнечная система -Космос». Все объекты этой грандиозной системы («малые» и «большие») связаны между собой опосредованным единством функциональности. Суммарное действие всех видов излучений, силовых полей и энергий, циркулирующих между космическими объектами (как вселенский океан взаимовлияний), представляет собой единое поле энергоинформационного обмена, которое также отождествляют с действием «Мировой энергии». Ключевые слова: эволюция, вселенский океан взаимовлияний, энергоинформационный обмен, движущие силы эволюции

The thesis deals with the use of counterfactuals in historiography from the point of view of causal explanation. It studies the various roles that counterfactual claims and counterfactual reasoning play in causal explanation and causal thinking in historiography. The aim is to defend the use of counterfactual what if -questions and inferences in the context of causal explanation and to create methodological guidelines for that use. The theory that is used in this thesis to explicate the role counterfactuals in causal explanation is the contrastive counterfactual theory of causal explanation.
