La concentration atmosphérique en gaz à effet de serre, responsable du réchauffement du climat, ne cesse d'augmenter depuis le début de l'ère industrielle. Les hypothèses médianes du groupe international d'experts sur le changement climatique (IPCC) prédisent un doublement de la concentration en dioxyde de carbone (CO2) avant la fin de ce siècle. De plus, la concentration d'autres gaz à effet de serre au pouvoir radiatif supérieur à celui du CO2 augmente, comme par exemple le méthane (CH4) et le protoxyde d’azote (N2O). Le N2O présente un potentiel de réchauffement d’environ 310 fois plus élevé que celui du CO2 avec une durée de vie de 120 à 150 ans. Son augmentation actuelle de 0.3% par an de sa concentration est imputable à l’activité anthropique incluant des processus industriels via l’utilisation de solvants mais surtout aux activités agricoles pour environ 70% via des processus biologiques de nitrification et dénitrification se produisant dans les sols. Afin de mieux comprendre l’effet des pratiques agricoles sur les échanges gazeux entre les sols et l’atmosphère, il faut quantifier les flux réels en fonction des différents types de sols, de pratiques culturales, de climats et d’écosystèmes. La limite actuelle de mesure de ces flux (notamment pour le N2O) réside dans la mauvaise sensibilité et stabilité des instruments de mesure en conditions de terrain. Depuis peu le GSMA (Groupe de Spectroscopie Moléculaire et Atmosphérique) a mis au point une station nommée ECoFlux (Eddy Covariance Flux) utilisant un senseur innovant reposant sur la spectrométrie laser infrarouge. Il permet de déterminer simultanément les flux in situ de N2O, CO2 et H2O par la méthode de covariance. Après une présentation du principe de la station ECoFlux, nous exposerons les résultats de deux campagnes de mesure sur des sites « grandes cultures » de suivi de gaz à effet de serre appartenant au réseau ICOS (http://www.icos-infrastructure.eu/). Nous terminerons en développant les intérêts et les modalités du déploiement de cette station sur site viticole [less ▲]

Cotton is the first export crop in Mali with 84,370 billion Fcfa in 2010 (INSTAT, 2010), but the production of this crop has huge problems due to external factors (prices of inputs and seed cotton) and internal (within payment to producers, internal debts of cooperatives). To boost cotton production during the years 2010/11 and 2011/12, the government had maintained the level of fertilizer subsidy at 50% of normal price on the market. In addition to this level of subsidy, the incentive price of 255Fcfa / kg was fixed to the producer and the National Union of Cotton Producers Cooperative Societies (NU-CPCS) facilitated the clearance of the internal debts of cooperatives. Despite the fall in world prices after 2011/12, the price of cotton seed remains little changed. The price stayed at 255 CFA francs / kg in 2012/13 and got back to 250 CFA francs / kg in 2013/14. The objective of this work is to analyze the effects of incentives factors cotton production with a view to the privatization of CMDT subsidiaries Surveys were conducted with a sample of 240 farms selected from the four zones of the CMDT zones based on two villages subsidiary during the years of 2008/09, 2010/11 and 2011/12. The results showed a positive trend in production (mainly due to an increase in the area) and in the income of cotton producers with a higher reimbursement rate of input credits under cultivation. The analysis of the Domestic Resource Cost (DRC) the Nominal protection coefficients (NPC) and the Effective (CPE) showed an improvement in thèse variables in 2011/12 with the incentive policy. An analysis of the determinants of the supply of cotton showed that only two variables were significant: the price cottonseed and payment period. The incentive factors are influenced by fiber market in 2011/12 which took a downward trend from the campaign. This incentive policy being favored by the market of fiber which is very unstable, it would be necessary to create conditions in which the producer can benefit from the price obtained on the quality of fiber to maintain the incentive policy for producers. For the privatization of Cotton Company, an upgrade of this company is necessary with the support of the Malian state. But this upgrade should not affect too much the selling price of sale of cotton that can bring new companies in a situation of too long term recovery of capital invested (long period of investment recovery). The privatization scheme as presented makes major companies more competitive. In order to reduce the operating costs a form of collaborative relationships among delivery companies would be required. Keywords: fertilizer subsidy, incentive price, cotton sector in Mali, privatization subsidiary, competitiveness. [less ▲]

Iron transport in plasma is carried out by transferrin, which donates iron to cells through its interaction with a specific membrane receptor. The soluble form of the transferrin receptor has been identified in plasma. Dosage of the soluble receptor represents a simple, reliable, quantitative assay of erythropoiesis, which should replace the standard ferrokinetic measurement. Using this dosage, it is now possible to investigate the pathophysiology of anemia in many conditions, and to analyze the erythropoietic response to treatment with recombinant erythropoietin.

Mesydel is a computer tool aiming at faithfully implementing a large subset of the features of a Delphi survey: collection of data, multiple rounds of questionnaires, address book management, treatment and analysis of qualitative and quantitative questions, and dedicated analysis tools. The Delphi method, one of the most renowned "expert" methods, is a prospective (also called foresight) method, which allows to survey a panel of experts – a recent trend tends to extend the meaning of experts to "experts of use", i.e. any layman/laywoman which, by his/her very position, has acquired some kind of knowledge on a particular topic – in an iterative way: a typical Delphi survey consists of two rounds at least, with, between each round, a synthesis that is used as a base for the following questionnaire, allowing a "controlled feedback". One important feature of the method is that it is based on the intuitions and insights of a panel of experts. These experts do not have access to the answers of their peers, which avoids the self-moderation bias: in a situation where such confidentiality were not established, experts could chose to adopt more consensual answers and to express less clear, softer opinions. The Delphi method proved to be efficient in creating "futuribles", i.e. scenarios that are deemed possible, but not certain. [less ▲]
