Cet article part du constat que la Chine a fortement accru sa présence en Amérique latine durant la dernière décennie. Il observe plus précisément que les pays avec lesquels elle a rapidement augmenté ses échanges économiques et commerciaux se sont également engagés dans de nouveaux schémas de coopération et partenariat, posant la question de la Chine comme potentielle « alternative » aux partenaires occidentaux traditionnels de ce sous-continent. Là où nombre d’études s’interrogent sur l’impact des relations sino-latino-américaines, celle-ci propose d’analyser la stratégie chinoise envers l’Amérique latine, en s’appuyant sur le cas du partenariat stratégique avec le Brésil. Dans ce cadre, nous postulons que l’accroissement de l’influence de la Chine dans cette région du monde ne dépend pas seulement de la disponibilité de ses ressources (économiques, politiques, culturelles, militaires, etc.), ni de son aptitude à les mobiliser adéquatement, mais qu’elle tient également à la représentation qu’elle véhicule en tant qu’acteur mondial (coopération Sud-Sud) ainsi qu’à sa reconnaissance par les autres acteurs du système international. En ce sens, la puissance de la Chine se mesure également à travers sa capacité à s’affirmer comme une référence pour ses pairs émergents, voire auprès des puissances occidentales. En appréhendant les différentes dimensions de la puissance chinoise à travers ses actions de politique extérieure et les discours afférents, nous mesurerons dès lors la capacité d’influence de la Chine en Amérique latine, et plus précisément vis-à-vis du Brésil, à travers l’écart entre son discours (coopération) et la réalité (hégémonie).

Background: Performance-Based Financing (PBF) has been advanced as a solution to contribute to improving the performance of health systems in developing countries. This is the case in Benin. This study aims to analyse how two PBF approaches, piloted in Benin, behave during implementation and what effects they produce, through investigating how local stakeholders perceive the introduction of PBF, how they adapt the different approaches during implementation, and the behavioural interactions induced by PBF. Methods: The research rests on a socio-anthropological approach and qualitative methods. The design is a case study in two health districts selected on purpose. The selection of health facilities was also done on purpose, until we reached saturation of information. Information was collected through observation and semi-directive interviews supported by an interview guide. Data was analysed through contents and discourse analysis. Results: The Ministry of Health (MoH) strongly supports PBF, but it is not well integrated with other ongoing reforms and processes. Field actors welcome PBF but still do not have a sense of ownership about it. The two PBF approaches differ notably as for the organs in charge of verification. Performance premiums are granted according to a limited number of quantitative indicators plus an extensive qualitative checklist. PBF matrices and verification missions come in addition to routine monitoring. Local stakeholders accommodate theoretical approaches. Globally, staff is satisfied with PBF and welcomes additional supervision and training. Health providers reckon that PBF forces them to depart from routine, to be more professional and to respect national norms. A major issue is the perceived unfairness in premium distribution. Even if health staff often refer to financial premiums, actually the latter are probably too weak — and ‘blurred’ — to have a lasting inciting effect. It rather seems that PBF motivates health workers through other elements of its ‘package’, especially formative supervisions. Conclusion: If the global picture is quite positive, several issues could jeopardise the success of PBF. It appears crucial to reduce the perceived unfairness in the system, notably through enhancing all facilities’ capacities to ensure they are in line with national norms, as well as to ensure financial and institutional sustainability of the system.

The dynamics of elasto-inertial turbulence is investigated numerically from the perspective of the coupling between polymer dynamics and flow structures. In particular, direct numerical simulations of channel flow with Reynolds numbers ranging from 1000 to 6000 are used to study the formation and dynamics of elastic instabilities and their effects on the flow. Based on the splitting of the pressure into inertial and polymeric contributions, it is shown that the polymeric pressure is a non-negligible component of the total pressure fluctuations, although the rapid inertial part dominates. Unlike Newtonian flows, the slow inertial part is almost negligible in elasto-inertial turbulence. Statistics on the different terms of the Reynolds stress transport equation also illustrate the energy transfers between polymers and turbulence and the redistributive role of pressure. Finally, the trains of cylindrical structures around sheets of high polymer extension that are characteristics of elasto-inertial turbulence are shown to be correlated with the polymeric pressure fluctuations.

Au début du 20e siècle, la poésie éprouve la tentation de la prose : nombre de poètes, lassés par des formes qu'ils jugent épuisées ou obsolètes, cherchent des voies nouvelles hors des vers et se font prosateurs. Apollinaire est de ceux-là. Les études réunies ici s'attachent à montrer de quelle façon il nous invite à admettre que la poésie trouve aussi bien sa place entre vers et prose que dans des formes scripturales et graphiques nouvelles, d'une hybridité déroutante (ni pleinement prose, ni pleinement vers, ou mi-prose, mi-vers) ou encore s'inscrit, comme le calligramme, dans la dimension spatiale. Apollinaire, poète en prose et inventeur de formes, apparaît ainsi comme étant toujours en quête d'un langage et d'un lyrisme neufs jusqu'à perdre le vers : "Perdre Mais perdre vraiment Pour laisser place à la trouvaille".

Background: This review discusses the advantages of transcranial magnetic stimulation combined with high-density electroencephalography (TMS-hdEEG) over other current techniques of brain imaging. Methods and results: Its application was reviewed, focusing particularly on disorders of consciousness, in the perspective of recent theories of consciousness. Assessment of non-communicative patients with disorders of consciousness remains a clinical challenge and objective measures of the level of consciousness are still needed. Current theories suggest that a key requirement for consciousness is the brain’s capacity to rapidly integrate information across different specialized cortical areas. TMS-EEG allows the stimulation of any given cortical area and the recording of the immediate electrical cortical response. This technique has recently been successfully employed to measure changes in brain complexity under physiological, pharmacological and pathological conditions. Conclusions: This suggests that TMS-EEG is a reliable tool to discriminate between conscious and unconscious patients at the single subject level. Future works are needed to validate and implement this technique as a clinical tool. [less ▲]

A two-level adaptive control scheme against power system voltage instability is proposed, to deal with emergency conditions by acting on distribution transformers and/or by curtailing some loads. The lower level includes distributed controllers, each acting once the voltage at a monitored transmission bus settles below a threshold value. The upper level benefits from wide-area monitoring and adjusts in real-time the voltage thresholds of the local controllers. Emergency detection is based on the sign of sensitivities. The proposed scheme is robust with respect to communication failures. Its performance is illustrated through detailed simulations of a small but realistic 74-bus test system. [less ▲]

The current environmental and agronomical context requires that farmers manage their inputs with the utmost precision, which can only be achieved by developing state of the art tools leading to clear, exhaustive and efficient decisions. In this context, soil analysis being a vital tool, we have endeavoured to refine the advice given to farmers by the Walloon soil analysis laboratories, members of the non-profit-making organization REQUASUD, by studying the opportunity of developing two complementary tools, one cartographic, the other analytical, which can be integrated in the daily running of a laboratory. First of all, to ensure that soil analysis provides reliable results, it is essential for the sample to be as representative as possible of the plot. Lacking this representativity, an analytical result, however accurate, would be devoid of meaning and give the farmer misleading advice. In the field, the main obstacle for the soil sampler is the recognition of soil criteria which are however essential in establishing fertility advice, especially in Wallonia (southern Belgium) due to a high soil variability. The Digital Soil Map of Wallonia, surveyed at a scale of 1/5000, should prove to be an invaluable tool that can be used easily and directly for routine work not only by soil samplers but also by farmers and agronomists. That’s why a mapping web portal REQUACARTO has been designed to help define homogenous morpho-pedological areas and to validate them in different situations. Furthermore, in Wallonia, certain soil properties seldom undergo routine analysis, despite their importance in fertility advice, and when they do, they result in the use of extracts which are harmful to the environment and to health. Therefore we investigated the feasibility of a routine application of near infrared reflectance spectroscopy (NIRS) to determine these soil properties. This technique offers a number of advantages compared to analyses carried out according to reference methods: speed, respect of the environment and health, recovery of the sample, ease of use and thus economy. On a selection of representative samples of the pedological context of Wallonia, for which we also had analytical results of exchange cation capacity, as well as rates of carbon, nitrogen and clay, trials were performed using NIRS instead of or in addition to laboratory reference analyses. The findings highlight the relevance of using NIRS and were substantiated by a study of repeatability and intermediate precision of the technique. The spectral library was then transferred to the different soil analysis laboratories of the network. The goal is multiple: to offer further analyses to farmers at no extra cost, reduce the number of analyses performed according to reference methods and implement the spectral library with samples not predicted by NIRS to improve predictions.

Three types of photocatalysts were synthesized by metal organic chemical vapor deposition and impregnation methods using the almond shell activated carbon as support. These photocatalysts denoted by (TiO2/ASAC (V), TiO2/ASAC (I1) and TiO2/ASAC (I2)) were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance spectroscopy (DRS) and nitrogen adsorptionedesorption isotherms. SEM observation shows that TiO2 was deposited on activated carbon surface. XRD results confirm that TiO2 existed in a mixture of anatase and rutile phases. The DRS spectra show the characteristic absorption edge of TiO2 at approximate 380 nm corresponding to the optical band gap of 3.26 eV. Besides, FTIR spectrum indicated the presence of (TieO) groups. The specific surface area of photocatalysts decreased drastically in comparison with the original activated carbon. The catalysts were very efficient for the photodegradation of total organic carbon (TOC) from industrial phosphoric acid solution under UV irradiation. The kinetics of photocatalytic TOC degradation was found to follow a pseudofirst- order model. The prepared TiO2/ASAC showed high photoactivity for the photodegradation of TOC in the following order: TiO2/ASAC (V) > TiO2/ASAC (I1) > TiO2/ASAC (I2) > ASAC > TiO2 (P25). [less ▲]
