| Gross sedimentation rates (GSR) were measured using sediment traps placed at different levels above die seabed (0.3, 0.5, 0.8, 1.0, 2.0, 4.0, 6.0, 8.0, 10.0 m) at a water depth of 17 m. The traps were deployed for 1.25 year. The study was carried out at a location in die semi-enclosed Aarhus Bay, in the southwestern part of the Kattegat, which forms the transitional zone between the highly saline (32-34) North Sea and the less saline (15-20) Baltic Sea. Hydrographic conditions in the Aarhus Bay are dominated by significant changes in salinity during the year, and the water column was stratified for 80 % of the time. High GSR values were recorded near the seabed with a mean of 114.8 (g m-2 day-1) at 0.3 m above the seabed, whereas low GSR values were... |

| En Am??rica Latina, la cobertura escolar, a??n sigue siendo un reto a cumplir; sin embargo, cada vez se posiciona en el lenguaje educativo y en los marcos legales, el concepto calidad de la educaci??n. Hasta hace poco, -al menos en Ecuador-, referirse a la calidad era parte de un discurso sin contenido real, lejano, que deb??a hacerse, pero que el Estado y la sociedad no lo asum??an como un derecho. Cada vez esta situaci??n ha ido cambiando, -para bien, por cierto-, y hoy, entre la primera y segunda d??cada del siglo XXI, hablar de calidad y exigir calidad a la escuela, es parte de la cotidianidad: el Estado lo plantea, la ciudadan??a lo exige, el poder pol??tico hace suyo en el discurso, los centros escolares buscan lograr calidad y asumir retos, los... |
