Nomenclátor Geográfico Básico de España v.1.0

El Nomenclátor Geográfico Básico de España (NGBE) es un proyecto desarrollado por el Registro Central de Cartografía (RCC) del Instituto Geográfico Nacional (IGN) en cumplimiento con lo establecido en el Real Decreto 1545/2007, de 23 de noviembre, por el cual se regula el Sistema Cartográfico Nacional. La formación de la primera versión del Nomenclátor Geográfico Básico de España se ha realizado en el período comprendido entre los años 2010 y 2012 y ha consistido en la depuración de los nombres geográficos procedentes de la cartografía del Instituto Geográfico Nacional a escala 1:25.000 a través de una metodología generada en el marco de este proyecto y estructurando el resultado en función del modelo de nomenclátor de INSPIRE (D2.8.I.3 INSPIRE Data Specification on Geographical Names-Guidelines).

In vitro evaluation of commercial fibrolytic enzymes for improving the nutritive value of low-quality forages.

The aim of this work was to assess the effects of four doses of three commercial fibrolytic enzymes on ruminal fermentation of rice straw, maize stover and Pennisetum purpureum clon Cuba CT115 hay in batch cultures of ruminal micro-organisms from sheep. One enzyme was produced by Penicillium funiculosum (PEN) and two were from Trichoderma longibrachiatum (TL1 and TL2). Each liquid enzyme was diluted 200 (D1), 100 (D2), 50 (D3) and 10 (D4) - fold and applied to each substrate in quadruplicate over time and incubated for 120 h in rumen fluid. The D4 dose of each enzyme increased (P<0.05) the fractional rate of gas production and organic matter effective degradability for all substrates, and TL2 had similar effects when applied at D3. In 9 h incubations, PEN at D4, TL1 at all tested doses, and TL2 at D2, D3 and D4 increased (P<0.05) volatile fatty acid production and dry matter degradability for all substrates. The commercial enzymes tested were effective at increasing in vitro ruminal fermentation of low-quality forages, although effective doses varied with the enzyme.

Dispositivos contemporáneos ante el reto del neomadismo

Cuatro dispositivos. Cuatro golpes de vista deteniéndonos sobre aspectos de la realidad contemporánea en los que juzgamos pertinente reparar. Usuarios transeúntes a través de los locutorios[D1], entornos dinámicos mediante la sucesión ecológica[D2], sistema de gestión de la propiedad obsoleto ante la realidad de flujos económicojurídicos[D3] y estructuras topológicas electromagnéticas que permiten desplazarnos con unos mínimos comunes[D4]. Modelos transdisciplinares muy directos elegidos por su efectividad ante la inestabilidad, arquetipos de los que tendremos que transferir claves a nuestra disciplina. ABSTRACT. Four devices. Four glances stopping on aspects of the contemporary reality in which we judge relevant to look at. Transient users across the phone booths[D1], dynamic environments through the ecological succession[D2], obsolete property management system facing the reality of financial and law flows[D3] and topological electromagnetic structures that allow our displacements with a few common minimums[D4]. Very direct transdisciplinary models chosen by their efficiency with the instability, archetypes from which we will have to transfer keys to our discipline

Yield, nutrient utilization and soil properties in a melon crop amended with wine-distillery waste

In Spain, large quantities of wine are produced every year (3,339,700 tonnes in 2011) (FAO, 2011) with the consequent waste generation. During the winemaking process, solid residues like grape stalks are generated, as well as grape marc and wine lees as by-products. According to the Council Regulation (EC) 1493/1999 on the common organization of the wine market, by-products coming from the winery industry must be sent to alcohol-distilleries to generate exhausted grape marc and vinasses. With an adequate composting treatment, these wastes can be applied to soils as a source of nutrients and organic matter. A three-year field experiment (2011, 2012 and 2013) was carried out in Ciudad Real (central Spain) to study the effects of wine-distillery waste compost application in a melon crop (Cucumis melo L.). Melon crop has been traditionally cultivated in this area with high inputs of water and fertilizers, but no antecedents of application of winery wastes are known. In a randomized complete block design, four treatments were compared: three compost doses consisted of 6.7 (D1), 13.3 (D2) and 20 t compost ha-1 (D3), and a control treatment without compost addition (D0). The soil was a shallow sandy-loam (Petrocalcic Palexeralfs) with a depth of 0.60 m and a discontinuous petrocalcic horizon between 0.60 and 0.70 m, slightly basic (pH 8.4), poor in organic matter (0.24%), rich in potassium (410 ppm) and with a medium level of phosphorus (22.1 ppm). During each growing period four harvests were carried out and total and marketable yield (fruits weighting <1 kg or visually rotten were not considered), fruit average weight and fruit number per plant were determined. At the end of the crop cycle, four plants per treatment were sampled and the nutrient content (N, P and K) was determined. Soil samplings (0-30 cm depth) were carried before the application of compost and at the end of each growing season and available N and P, as well as exchangeable K content were analyzed. With this information, an integrated analysis was carried out with the aim to evaluate the suitability of this compost as organic amendment.

Treatment of tropical forages with exogenous fibrolytiic enzymes: effects on chemical composition and in vitro rumen fermentation

The effects of three treatments of fibrolytic enzymes (cellulase from Trichoderma longibrachiatum (CEL), xylanase from rumen micro-organisms (XYL) and a 1:1 mixture of CEL and XYL (MIX) on the in vitro fermentation of two samples of Pennisetum clandestinum (P1 and P2), two samples of Dichanthium aristatum (D1 and D2) and one sample of each Acacia decurrens and Acacia mangium (A1 and A2) were investigated. The first experiment compared the effects of two methods of applying the enzymes to forages, either at the time of incubation or 24 h before, on the in vitro gas production. In general, the 24 h pre-treatment resulted in higher values of gas production rate, and this application method was chosen for a second study investigating the effects of enzymes on chemical composition and in vitro fermentation of forages. The pre-treatment with CEL for 24 h reduced (p < 0.05) the content of neutral detergent fibre (NDF) of P1, P2, D1 and D2, and that of MIX reduced the NDF content of P1 and D1, but XYL had no effect on any forage. The CEL treatment increased (p < 0.05) total volatile fatty acid (VFA) production for all forages (ranging from 8.6% to 22.7%), but in general, no effects of MIX and XYL were observed. For both P. clandestinum samples, CEL treatment reduced (p < 0.05) the molar proportion of acetate and increased (p < 0.05) that of butyrate, but only subtle changes in VFA profile were observed for the rest of forages. Under the conditions of the present experiment, the treatment of tropical forages with CEL stimulated their in vitro ruminal fermentation, but XYL did not produce any positive effect. These results showed clearly that effectiveness of enzymes varied with the incubated forage and further study is warranted to investigate specific, optimal enzyme-substrate combinations.
