Evolution tectono-sédimentaire et magmatique des bassins viséen supérieur d’Azrou-Khénifra et des Jebilet orientales (Meseta marocaine)

During Upper Visean times, the eastern mesetian basins of eastern Jebilet and Azrou Khenifra show great tectono-sedimentary and magmatic evolution similarities. Their deposits record large instabilities and disorganization with huge thickness and lithological variations, related to a synsedimentary tectonic context. At the same time, tilted block tectonics affect the basement of these basins, controlled by bordering transfert faults. Basic dominant magmatic bodies set up in these basins. Their continental alkaline chemical characteristics are consistent with the regional geodynamic context in this area. Initiated along the transitional zone between eastern and western Meseta, the Azrou-Khenifra and Jebilet basins correspond to intracontinental throws, initiated on and controlled by major strike-slip faults. Their evolution is most likely earlier in time and of a weak opening rate than the neighboring western Meseta basins.Au Viséen supérieur, les bassins mesetiens des Jebilet orientales et d’Azrou Khénifra montrent de grandes similitudes de leur évolution tectono-sédimentaire et magmatiques. Leurs dépôts enregistrent de grandes instabilités liées à une tectonique syn-sédimentaire responsable localement d’une intense désorganisation et de grandes variations de faciès et d’épaisseurs. Ces instabilités sont engendrées par une tectonique en blocs basculés qui affecte le substratum anté-Viséen, contrôlée par des accidents bordiers sub-verticaux à forte composante transcurrente. Des corps magmatiques, pour l’essentiel basiques, se mettent en place dans ces bassins. Ils présentent des caractères chimiques des séries magmatiques alcalines mise en place dans un contexte intracontinental et anorogénique. Initiés le long de la zone de transition entre la Meseta orientale et occidentale, les bassins d’Azrou-Khénifra et des Jebilet orientales correspondent à des sillons intracontinentaux, initiés et contrôlés par des décrochements. Leur évolution est sans doute plus précoce et montre un faible taux d’ouverture que celui enregistré dans les bassins adjacents de la meseta occidentale

Cartography of Suicide-Related Health Indicators and Suicide Attempts in Morocco

The present work consists of a retrospective study of suicidal intoxication during a period stretching from January 1980 to December 2013, reported to the Poison Control and Pharmaco-vigilance Center of Morocco through two systems of data collection: Toxicological Information and Toxico-vigilance. The objective is to determine the spatio-temporal evolution of the incidence, lethality and mortality related to suicides and suicide attempts through intoxication in Morocco. During the study period, the average annual number of suicidal intoxications was 707 cases. All regions of Morocco have been affected but at variable rates. The average age of the victims is 24.39 ± 0.08 years, with a sex ratio of 2.41 in favor of the female sex. In the space of 34 years, the incidence is 2.4 per 100,000 inhabitants, the mortality is 0.67 per million inhabitants and the lethality is 0.08%. The annual increase in biological indicators makes suicides and suicide attempts a public health problem, through hospital care and the resulting socio-economic and psychological consequences. This problem seems much more common in urban areas and particularly in the big cities of Morocco

Impact of climate change on forest resources: Case of Quercus rotundifolia, Tetraclinis articulata, Juniperus phoenicea, J. oxycedrus, J. thurifera and Pinus halepensis

Forest resources in the Ourika watershed are subject to several anthropogenic and climatic degradation factors. As for the human factor, this degradation of forest resources is explained by the bad practices exercised by the local population expressed by the cutting of live wood, carbonization, and overgrazing. In terms of the climatic factor, the decrease in the amount of rainfall and the increase in temperature contribute to the exacerbation of the degradation of these resources. In order to better understand the evolution of plant cover in a changing climate context, this study highlights an assessment of the impact of climate change on forest dynamics based on a process-based model at the forest landscape scale which makes it possible to simulate the changes according to growth, succession, disturbances (fire, wind, insects, etc), forest management, and land use change. This analysis is based on the use of the LANDIS-II model and the PnET-succession extension. Projections of the dynamics of forest communities are made using climate projections from the Japanese global circulation model adopted by Morocco (model for interdisciplinary research on climate – earth system models) and this by adopting the two climate scenarios , representative concentration pathways 4.5 and 8.5. The results obtained highlight the spatial distribution of the ecosystems studied after 100 years with a quantitative evaluation of the total average biomass of these resources as a function of climatic disturbances. In general, the estimated total biomass will decline over the coming years under the joint effect of the climate change and the aging of forest stands, while on the other hand, the distribution of potential areas for species settlement remains independent of the effect of these climate changes

La presencia de la islamofobia en Twitter: análisis de cuentas con mensajes islamófobos publicados en español

Esta investigación analiza la islamofobia en la red social de Twitter, prestando especial atención a los discursos de odio. Se identifican estereotipos y prejuicios difundidos sobre la población musulmana, analizando la forma en que se amplifica la islamofobia en las redes sociales y proponiendo una serie de recomendaciones para contrarrestarla. La metodología usada es la de análisis de contenido, examinando una cuenta de usuario como objeto de estudio. Dentro de la misma se estudia los discursos de odio y discriminación hacia los musulmanes, permitiendo reforzar una visión negativa y estigmatizada del islam que contribuye a la perpetuación de la islamofobia en línea.Grado en Publicidad y Relaciones Pública
