This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

This book was released on 2013-10-09 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les sociétés accumulent un volume considérable de connaissances techniques, environnementales, sociales, économiques et fiscales. Elles doivent rester pertinentes dans l’organisation et l’exploitation de cette masse d’information, et également apprendre à collaborer avec les outils de Knowledge Management. Cet ouvrage présente une démarche originale de mise en œuvre d'un système de management des connaissances qui comprend : - l’intégration d'infrastructures et l’utilisation des ressources externes ou internes, - les architectures fonctionnelles et techniques, - les technologies du Web 2.0, - les modes de gestion des connaissances et des métadonnées, - le modèle de traitement adapté, - la circulation des flux de connaissance. Cette évolution des usages nécessite la mise en place de nouveaux modes de management dans l'entreprise afin de préparer, conduire, expliquer les actions et définir les axes stratégiques. Le but étant ici de mettre en place un système efficace de gestion des connaissances évoluant vers des offres de services applicables à toute forme d’organisation : le Knowledge Management.

This book was released on 2013-12-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: 0.1 Gaps in Optimizing A comparison of the levels of development of Operations Research, Simulation Technique and Optimal Control Theory appears to gain increasing interest. Operations Research Sciences achieved very high mathematical standards and solved a great amount of important optimization problems, mainly at the level of management of private corporation and civil or military government tasks, however, these achievements are seldom incorporated in the mathematical curriculum of modern universities. Nevertheless, Operations Research seems to have failed in solving long range or strategical problems as they arise in any broader social, economical or political context (MUller-Merbach, 1976). Also for the weakest task, namely that of improving theory building, system simulation works as an optimization tool. Simulation models of large complex systems, like socio economical or political ones, failed until now to fit large empirical data bases. This was, in fact, one of the few serious objections against the form in which Forrester solved some problems modelling and simulating urban and world de velopments (Forrester, 1969; Forrester, 1971; IEEE-SCC October 197o; IEEE-SMC April 1972; Mass, 1974; Schroeder, 1975).

This book was released on 2018-10-26 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascicle is the thirteenth in the series of Level One publications of the excavations at Franchthi Cave and is the third and final installment of the report on the site's chipped stone industries. The objective of Catherine Perlès's study is to make sense of the chronology of the site in its economic, technological, and typological dimensions. All phases of the Neolithic are represented at Franchthi Cave. Rich with more than 3,000 reconstructed pieces, this study offers a representative and technical typology that is unequaled today. The first part of the analysis offers diagnostic elements to facilitate comparisons between the lithic sequence and surface dating and is more descriptive than interpretive. The second part is dedicated to a step-by-step analysis of the Franchthi material in a well-defined chrono-stratigraphical framework. The third and most interpretive portion of the study addresses itself more specifically to those who are interested in the socio-economic organizational problems of Neolithic societies.
