Témoignant au nom des hommes, les écrivains participent aux commémorations : journalistes, ils rendent compte des cérémonies officielles ; romanciers, ils dédient leurs livres aux disparus ; poètes, ils chantent la mémoire des morts afin que les actions passées, héroïques ou modestes, guerrières ou quotidiennes, ne s'oublient pas. Mais certains contestent la nécessité du souvenir dont la construction, dans la société post moderne, est parfois ambiguë. Et il y a une autre façon de s'opposer à la violence du monde : le silence.

Les écrivains combattants de la Première Guerre mondiale ou d'autres conflits racontent dans leurs œuvres ce qui s'apparente à un retour de l'Enfer, le royaume d'Hadès. Ils ont rencontré la mort. Rescapés de la bataille, ils rendent compte de cette expérience douloureuse. En cela semblables aux textes anciens tels que l' Odyssée ou l' Énéide , leurs écrits renvoient à certains grands mythes, celui d'Orphée en particulier.

The article summarizes 18 yrs of activities of UNESCO meant to develop U teaching & fundamental res in the soc sci field. Starting with a recapitulation of clearly internat'l efforts consisting in surveys of existing facilities by disciplines, regions & countries in diff cultural settings, as well as the publication of bibliographies & other documentary material, a bird's eye view is given of brief or long-term missions of soc sci'st's to diff parts of the world, & an assessment of 5 regional training & res centers founded by or under the auspices of UNESCO. An outline is presented of the main obstacles encountered in such endeavors for implanting diff soc sci disciplines in the academic circles of the developing countries. AA.

In Mali, the deficiency of agricultural soils in phosphorus is one of the limiting factors in crop production. They respond well to phosphorus fertilization, but the high price of imported chemical fertilizers limits their use by the producers. However, Mali has large deposits of natural phosphate in the Tilemsi Valley (PNT) in northern Mali. Faced with this situation, the Government encouraged the use of local fertilizing resources including the PNT. Despite the satisfactory results of several years of research and popularization, the PNT was poorly adopted by the producers because of its powdery appearance, which made it difficult to apply in the field, its low solubility in the soil, which made its effect noticeable on crops in the second year of its application and its brown color reminiscent of that of earth made the producers believe that it had no fertilizing value. Faced with these problems relating to the physical appearance and the low solubility of the PNT, the laboratory work of GREAT QUEST Fertilizer SA resulted in the development of simple formulations based on enriched granular PNT 27% P2O5 (average content) and 35% P2O5 (high content) for direct application and NPK complex formulations based on granulated enriched PNT 35% P2O5 mixed mainly with urea, potassium, and sometimes with other nutriments like sulfur and boron (NPK 15-15-15; NPKSB 14-18-18-6-2) with a solubility in citric acid of 71.1%. The results of four years of experimentation of enriched granular PNT in the research stations and in the peasant environment showed a greater or equal effect than the other popular fertilizers. This project aims to improve phosphate nutrition and crop production by using granulated formulations of enriched PNT 27% P2O5 and 35% P2O5.
