The composition of the food of the European grayling and the character of its feeding has been studied fully enough, but this knowledge is scattered in the literature and often contradictory. rare exceptions, analysis of the results of different investigations. Therefore the proposed short outline of the history of the study of the problem with a description of the basic data on the feeding of the grayling in different geographical areas is presented as expedient and opportune, primarily in relation to the determination of immediate problems and the trend of research.

[ES] El género Sabacon (Arachnida: Opiliones) tiene distribución holártica, y en la Península Ibérica se restringe a Pirineos y Cordillera Cantábrica. Se menciona la presencia de S.viscayanus en la Sierra Cebollera, a partir del hallazgo de una hembra, lo que constituye el primer registro al sur del Ebro. En este trabajo se ha determinado la subespecie a la que pertenece esa población gracias a la captura de un macho, que corresponde a Sabacon viscayanus viscayanus. Con los ejemplares de las colecciones (ZUPV y CRBA) se han redescrito las especies ibéricas y se ha descrito por primera vez el macho de S. franzi. A su vez, se han construido mapas de distribución de todas las especies con datos citados y de las colecciones propias.

Fisheries agreements with the European Community (EC) are an important component of the fisheries sector in Cape Verde and São Tomé e Príncipe, constituting today a key source of income for the respective fisheries administration. In spite of this, and of the fact that these agreements have been renewed several times over the past decades, challenges remain in domains such as control and communication of fishing activities, follow-up of financial counterparts, and integration of European fleets’ operations with the Cape Verdean and Santomean economies. This paper analyzes the EC fisheries agreements with Cape Verde and São Tomé e Príncipe in terms of those domains, considering both the contents of the agreements and their practical implementation. The fisheries sector in each of these countries is reviewed, as are some of the fundamentals and criticisms of EC fisheries agreements. It is argued that the agreements with Cape Verde and São Tomé e Príncipe will not live up to the stated objectives of sustainability and responsibility in fisheries until improvements are made to the control of EC vessels, the follow-up of funds paid by the EC, and the size and diversity of benefits accruing to the fisheries and related sectors in the two countries

With different implantation energies, nitrogen ions were implanted into SIMOX wafers in our work. And then the wafers were subsequently annealed to form separated by implantation of oxygen and nitrogen (SIMON) wafers. Secondary ion mass spectroscopy (SIMS) was used to observe the distribution of nitrogen and oxygen in the wafers. The result of electron paramagnetic resonance (EPR) was suggested by the dandling bonds densities in the wafers changed with N ions implantation energies. SIMON-based SIS capacitors were made. The results of the C-V test confirmed that the energy of nitrogen implantation affects the properties of the wafers, and the optimum implantation energy was determined. (c) 2005 Elsevier B.V.

Based on the conventional through-short-match (TSM) method, an improved TSM method has been proposed in this Letter. This method gives an analytical solution and has almost all the advantages of conventional TSM methods. For example, it has no phase uncertainty and no bandwidth limitation. The experimental results show that the accuracy can be significantly improved with this method. The proposed theory can be applied to the through-open-match (TOM) method. (C) 2002 Wiley Periodicals.
