L'invention concerne un gril ayant une configuration de dome a deux niveaux (3, 15), un ensemble bruleur (1) et une enceinte de gril (2). Le premier dome, ou dome inferieur (3), a une configuration en I. Le deuxieme dome (15), ou dome superieur, possede plusieurs ouvertures (19). L'ensemble bruleur (1) comprend un sous-ensemble bruleur (21, 22) et un sous-ensemble a passage venturi (25); les deux sont faits d'un metal matrice. La partie superieure (22) en metal matrice possede une zone surelevee ou emboutie (26) avec des orifices a plusieurs niveaux. Le systeme dome-bruleur assure une repartition reguliere de la chaleur a destination d'une surface de cuisson ainsi qu'une meilleure protection contre les flambees soudaines. L'utilisation d'un metal matrice pour l'ensemble bruleur permet d'obtenir un gril economique et d'assemblage facile.

The coastal strip of the western peri-urban area of Barranquilla in the Atlántico Department (Colombia) is experiencing changes in human-environment interactions through infrastructure, residential, and tourism projects in a vulnerable landscape. In the hilly area, fragments of biodiverse tropical dry forest still exist in various states of conservation and degradation. To understand the interrelated social, economic, and ecological transformations in the area, we analyzed land use change on the local scale including the local community’s perception, because the local community is a key actor for sustainable land use. For the analysis of the interrelated social, economic, and ecological processes, we combined visual interpretation of high-resolution satellite imagery, on-site field land use mapping, and a spatial statistical analysis of the distribution of land use classes with in-depth interviews and a participatory GIS workshop, thus benefitting from the complementary methodologic...

Barranquilla is known as a dynamically growing city in the Colombian Caribbean. Urbanisation induces land use and land cover (LULC) changes in the city and its hinterland affecting the region’s climate and biodiversity. This paper aims to identify the trends of land use and land cover changes in the hinterland of Barranquilla corresponding to 13 municipalities in the north of the Department Atlántico. Landsat TM/ETM/OLI imagery from 1985 to 2017 was used to map and analyse the spatio-temporal development of land use and land cover changes. During the investigation period, the settlement areas grew by approximately 50% (from 103.3 to 153.6 km2), while areas with woody vegetation cover experienced dynamic changes and increased in size since 2001. Peri-urban and rural areas were characterized by highly dynamic changes, particularly regarding clearing and recovery of vegetated areas. Regression analyses were performed to identify the impact factors of detected vegetation cover changes. ...
