Tracking the evolution of waste recycling research using overlay maps of science

Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by Rafols et al. (2010) to make a “double overlay map” of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

Rumbo al Gran Banco: una etnohistoria de la pesca industrial del bacalao en los Bancos de Terranova

[ES]Rumbo al Gran Banco parte de los comienzos de la pesca industrial del bacalao española en el primer tercio del siglo XX, la situación que allí encontraron, los avatares humanos y los avances tecnológicos que se van incorporando, la Guerra Civil y la guerra mundial, la bonanza pesquera, la incorporación de las parejas, la concurrencia, así como la exploración de todo el Gran Banco. La gestión por parte de Canadá de las doscientas millas marinas y la moratoria del bacalao. También se presenta la historia de la pesca en Galicia y Terranova a lo largo de todo el siglo XX, dos territorios que comparten el mismo océano y una mirada puesta en la mar.

Políticas de suelo industrial en Álava

(ES) En este artículo son analizadas las políticas de suelo industrial en Álava, uno de los tres territorios históricos o provincias), junto con Vizcaya y Guipúzcoa, que integra la Comunidad Autónoma del País Vasco (CAPV en adelante). En un primer apartado exponemos los planteamientos teóricos actuales que inspiran el diseño de las políticas en materia de suelo industrial y posteriormente valoramos las actuaciones y los resultados de los diferentes organismos que gestionan este tipo de suelo en Álava. Finalmente, avanzamos los resultados preliminares obtenidos mediante el SIG Alavamap.

Evaluation of Waterhyacinth and Paddy Straw Waste for Culture of Oyster Mushrooms

Waterhyacinth ( Eichhornia crassipes (Mart.) Solms.) was evaluated at ratios of 25, 50 and 75% with paddy straw ( Oryza sativa L.) for oyster mushroom ( Pleurotus sajor-caju) cultivation. There was an increase in yield with decreasing ratio waterhyacinth.
