Este artículo está dedicado a Julio Perceval (1903-1963) músico de origen belga que se radicó en la Argentina en 1926. Se ha enfocado en las etapas de su formación en Bruselas y su desarrollo profesional en Buenos Aires por medio de testimonios aportados por quienes compartieron el periodo de búsquedas juveniles del compositor. Para reconstruir el ambiente musical en la etapa belga han sido consultados trabajos de Robert Wangermée, en tanto que para conocer sus relaciones con colegas e intérpretes en Buenos Aires se ha contado con material del Archivo donado por la familia del músico a la Facultad de Artes y Diseño de la UNCuyo.

We present a high-resolution reconstruction of tropical palaeoenvironmental changes for the last deglacial transition (18 to 9 cal. kyr BP) based on integrated oceanic and terrestrial proxies from a Congo fan core. Pollen, grass cuticle, Pediastrum and dinoflagellate cyst fluxes, sedimentation rates and planktonic foraminiferal d18O ratios, uK37 sea-surface temperature and alkane/alkenone ratio data highlight a series of abrupt changes in Congo River palaeodischarge. A major discharge pulse is registered at around 13.0 cal. kyr BP which we attribute to latitudinal migration of the Intertropical Convergence Zone (ITCZ) during deglaciation. The data indicate abrupt and short-lived changes in the equatorial precipitation regime within a system of monsoonal dynamics forced by precessional cycles. The phases of enhanced Congo discharge stimulated river-induced upwelling and enhanced productivity in the adjacent ocean.

Planned to be a process of early evaluation of Politics, Plans and Programs (PPPs), which interfere in the environment; the Strategic Environmental Assessment (SEA) suggests a methodology for planning and managing the land, which overcomes the limitations of the traditional plans that try to mitigate the environmental impacts of Projects, assuming a pro-active conception that incorporates the social and environmental aspects in the planning stage of the PPPs. This kind of Evaluation surpasses the existing limitations of the Environmental Impact Assessment (EIA), once the EIA happens after the planning process, when lots of decisions have been made and carried out. In order to overcome the limitations of EIA, the SEA is a strategic tool in the process of planning and managing the land. When we focus on the PPPs and not on the Projects, the SEA, which is more political than technical, priorizes the strategies that assure the integration of the environmental, social, economic and institutional aspects into the planning process, in private or public organizations. In this context, this work aims to establish the concept basis of the Strategic Environmental Evaluation as a tool for land planning and managing. The methodology procedures used here lie in the literature review concerning the SEA, analyzing how this tool can be introduced as an alternative for sustainable development. Although the SEA is a tool that introduces the sustainable development theme as a guiding principle of planning, it is seldom used by managers and decision makers, locally and nationally

At marine seeps, methane is microbially oxidized resulting in the precipitation of carbonates close to the seafloor. Methane oxidation leads to sulfate depletion in sediment pore water, which induces a change in redox conditions. Rare earth element (REE) patterns of authigenic carbonate phases collected from modern seeps of the Gulf of Mexico, the Black Sea, and the Congo Fan were analyzed. Different carbonate minerals including aragonite and calcite with different crystal habits have been selected for analysis. Total REE content (SumREE) of seep carbonates varies widely, from 0.1 ppm to 42.5 ppm, but a common trend is that the SumREE in microcrystalline phases is higher than that of the associated later phases including micospar, sparite and blocky cement, suggesting that SumREE may be a function of diagenesis. The shale-normalized REE patterns of the seep carbonates often show different Ce anomalies even in samples from a specific site, suggesting that the formation conditions of seep carbonates are variable and complex. Overall, our results show that apart from anoxic, oxic conditions are at least temporarily common in seep environments.
