Euskalaritzaren historia eta historiografia: ikerketa-arloaren egoeraz

[EN] This paper attempts to summarize what is currently known about the History of Basque Linguistics. The first section tries to explain what is precisely meant by the term “euskalaritza" (Bascology) and proposes a provisional periodization of the History of Basque Linguistics. The second section outlines the factors which triggered the development of Basque Linguistic Historiography from the mid 80's --mainly the new interpretation of the 18th century Jesuit M. Larramendi's works-- and shows some of its consequences. The third section carries out the chief goal of the paper; the principal authors' works, and ideas emerging from the History of Basque Linguistics are there briefly noticed, and historiographical works concerning each one of them are mentioned along; special emphasis is laid on the most recent findings. Finally, a bibliographical appendix is provided containing the works by the old authors referred to throughout the paper.

Entre el rechazo frontal y la aceptación con condiciones: cónsules extranjeros en los puertos vascos entre los siglos XVI y XIX

[ES] El presente artículo analiza el establecimiento de cónsules de naciones extranjeras en los puertos vascos, desde el siglo XVI hasta la primera mitad del siglo XIX. Y lo hace en un lapso de tiempo tan amplio, precisamente para poder valorar las cons­ tantes y diferencias producidas. Para ello se ha hecho uso de los fondos del Archivo General de Gipuzkoa, del Archivo Histórico de la Diputación Foral de Bizkaia, del Archivo General de Simancas y de la Sección de Consejos Suprimidos del Archi­ vo Histórico Nacional, así como de la abundante bibliografía existente. El estudio demuestra que durante el período de estudio hubo una oposición frontal al esta­ blecimiento de representación consular extranjera —más tajante en San Sebastián que en Bilbao—, por considerarse que era una erosión del orden foral. Sin embargo, existió un tratamiento diferenciado en función de la nación pretendiente y de su peso específico en la economía local.

Effects of Lorentz local field correction on propagation properties of few-cycle pulse in dense Λ-type atomic medium

By solving numerically the full Maxwell-Bloch equations without the slowly varying envelope approximation and the rotating-wave approximation, we investigate the effects of Lorentz local field correction (LFC) on the propagation properties of few-cycle laser pulse in a dense A-type three-level atomic medium. We find that: when the area of the input pulse is larger, split of pulse occurs and the number of the sub-pulses with LFC is larger than that without LFC; at the same distance, the time interval between the first sub-pulse and the second sub-pulse in the case without LFC is longer than that with LFC, the time of pulse appearing in the case without LFC is later than that in the case with LFC, and the two phenomena are more obvious with propagation distance increasing; time evolution rules of the populations of levels vertical bar 1 >, vertical bar 2 > and vertical bar 3 > in the two cases with and without LFC are much different. When the area of the input pulse is smaller, effects of LFC on time evolutions of the pulse and populations are remarkably smaller than those in the case of larger area pulse. (c) 2008 Elsevier B.V.

Poverty alleviation among fishermen within the floodplains of Kaduna River: implication for introducing commercial fish farming at village level in Doko local government area of Niger State, Nigeria

A diagnostic survey was conducted among the fishermen in six selected villages in Doko Local Government Area of Niger State. One hundred and fifty fishermen were randomly selected and interviewed to find out whether or not they had interest in commercial fish farming aimed at improving their livelihood. The dwindling fish catches in the natural flood plain ponds and Ex-bow Lakes continue to have a serious negative effect on the socio-economic well being of the village communities in question. A break on natural regular annual flooding of the plains had resulted into very low natural fish recruitment. Data analysis using simple descriptive statistics revealed that land tenure system, educational status, inadequate infrastructural facilities, religious taboos, existing fish species among others were found to be favourable indices for commercial fish farming. However, serious conflicts among the fishermen concerning the ownership status of these natural fish ponds are found to be major obstacles to commercial fish farming despite that the traditional ownership of the ponds were vested in the lands of individuals and village communities. Extensive fish farming and small-scale fish farming in the ponds and Ex-bow Lake with improved management practices are considered to be profitable venture. Despite the fact that fish seeds supply and extension effort are still inadequate, the fish farmers have indicated willingness to adopt commercial fish farming in the Ex-bow Lakes and flood plains in order to restore abundant fish production thereby providing for their food security and also increasing the daily income

Impact assessment of Niger State fisheries legislation on fisheries conservation in Edozhigi local government area (L.G.A.) of Niger State

A preliminary survey was conducted among the fishermen in five selected villages in Edozhigi L.G.A. of Niger State. One hundred and fifty fishermen were randomly selected and interviewed to find out the impact of Niger State fisheries legislation on fisheries conservation resources in the area. The analysis of data collected using descriptive statistics indicated that undersized mesh of gill nets, beach seines and traps are being used unabated. Also, fenced barriers across the entrance of flood plain ponds and Ex-bow lakes from the main stream are in the area. The fisheries rules and regulations implementers are rarely seen or not seen at all in the area. The decreasing nature of fish catches was detected. It is observed that government policy on fish conversation is neglected due to inadequate or lack of funding for meaningful extension and implementation of the fisheries rules and regulations

The local-field corrective effect on Rabi oscillation of ultrashort pulse excitation in semiconductor GaAs

Rabi oscillation of the thin bulk semiconductor GaAs, which takes into account the effect of the local-field correction induced by the interacting excitons, is investigated by numerically solving the semiconductor Bloch equations. It is found, for a 2 pi few-cycle pulse excitation, that two incomplete Rabi-floppings emerge due to the competition between the Rabi frequency of the incident pulse and the internal-field matrices. Furthermore, for a sub-cycle 2 pi pulse excitation a complete Rabi-flopping can occur because of the absolute phase effect. We ascribe these characteristics of the Rabi oscillation to the renormalized Rabi frequency.

Historia de la piscicultura del pejerrey en Chascomús

El pejerrey Odontesthes bonariensis es uno de los peces de aguas continentales más emblemáticos de la Argentina y una de las especies más estudiada desde diferentes aspectos: ecológico, sistemático, morfológico, fisiológico, genético, etc. (López et al. 1991). Durante los años 1891 y 1892 se realizaron las primeras experiencias de piscicultura,lográndose por primera vez la reproducción artificial en 1904. Su amplia distribución actual es consecuencia de las siembras que se realizaron desde el antiguo Vivero de Piscicultura del Ministerio de Agricultura y Ganadería de la Nación y de la Estación Hidrobiológica del Ministerio de Asuntos Agrarios de la provincia de Buenos Aires, ambos establecimientos ubicados en la ciudad de Chascomús. En el presente trabajo se realiza una aproximación a la historia de la piscicultura del pejerrey en Chascomús, la que se divide en tres períodos: 1) Antecedentes de piscicultura, importancia de la pesca comercial en el sistema de lagunas Encadenadas de Chascomús y primeras medidas tomadas para conservar la explotación de las lagunas hacia fines del siglo XIX. 2) Etapa del antiguo Vivero (Ministerio de Agricultura de la Nación), desde 1904 hasta 1939. 3) Etapa de la Estación Hidrobiológica (Ministerio de Asuntos Agrarios, provincia de Buenos Aires), desde 1943 hasta el presente.

Intense local plasma heating by stopping of ultrashort ultraintense laser pulse in dense plasma

Self-trapping, stopping, and absorption of an ultrashort ultraintense linearly polarized laser pulse in a finite plasma slab of near-critical density is investigated by particle-in-cell simulation. As in the underdense plasma, an electron cavity is created by the pressure of the transmitted part of the light pulse and it traps the latter. Since the background plasma is at near-critical density, no wake plasma oscillation is created. The propagating self-trapped light rapidly comes to a stop inside the slab. Subsequent ion Coulomb explosion of the stopped cavity leads to explosive expulsion of its ions and formation of an extended channel having extremely low plasma density. The energetic Coulomb-exploded ions form shock layers of high density and temperature at the channel boundary. In contrast to a propagating pulse in a lower density plasma, here the energy of the trapped light is deposited onto a stationary and highly localized region of the plasma. This highly localized energy-deposition process can be relevant to the fast ignition scheme of inertial fusion.
