Epidémio-surveillance des vanilleraies de Mayotte et des Comores : rapport technique

Grâce à un financement du Fonds de Coopération Régionale de la Collectivité de Mayotte, une prospection a été réalisée visant à identifier les contraintes phytosanitaires prévalant dans les plantations de l'archipel des Comores (Figure 1). L'enquête a été réalisée à Mayotte, Grande Comore et Moheli entre le 23 avril et le 7 mai 2007, en collaboration avec la Chambre d'Agriculture, de la Pêche et de l'Aquaculture à Mayotte et le GIE "Maison des Epices" dans l'Union des Comores. L'île d'Anjouan n'a pu être prospectée comme prévu, en raison des tensions politiques qui n'ont cessé de prévaloir depuis mai 2007. Ce compte-rendu fait suite au rapport intermédiaire rédigé en juin 2007. II rappelle quelques éléments sur la diversité et la pathologie des vanilliers dans l'Océan Indien, présente les résultats des analyses effectuées sur les échantillons collectés au cours de la prospection et formule des recommandations techniques pour la gestion des ressources génétiques et des bio-agresseurs des vanilliers de l'archipel.

Research of quasi-solid fracture behavior of casting AI-4.5Cu alloys

The influencing mechanisms of elements Ti and Ce and their interactions on fracture behaviors of casting alloys AI-4.5Cu-0.6Mn were studied by observing tensile fracture behavior in quasi-solid zone under SEM and EDX instruments.The results indicate that the resistance stress against hot cracking can be improved obviously by addition of Ti, because of its grain refining function. It is also found that, when Ce is added into the alloys, besides its effect in refining crystalline, the mechanical behavior of lower melting point eutectic phase in quasi-solid zone can be improved efficiently by some compounds with Ce formed and deposited between dendrites. Therefore, a colligating effect of Ti and Ce on improving resistance stress against hot cracking is more efficient than that only single alloy element is applied. When hot cracking occurs, grains yield at first, and then crack spreads. Both inter-grain and trans-grain fractures are observed, but the major fracture manner is brittleness

Effect of Ba-Duan-Jin on Immune Function and Autonomic Nervous Balance in Ageing People

[Objective] Ba-Duan-Jin, formed in the 12th century, is an excellent traditional Chinese health exercises. Ancients likened it to “brocade (Jin)”, meaning its action is as elegant as brocade. The total movements are divided into 8 sections, so it is called “ Ba-Duan-Jin (8-section-action)”. Because of its simple action and significantly healthy effect, Ba-Duan-Jin is widely used to enhance physical fitness and prevent diseases. This study was aimed to evaluate the immunological effect of Ba-Duan-Jin in ageing people and analyze its autonomic nervous mechanism. [Methods] 60 healthy women (64.06±2.53 years old) were divided into exercising group and sedentary group. Exercising group trained Ba-Duan-Jin 12 weeks（5 day/week, 3 repetition/day）. Record electrocardiosignal to analyze heart rate variability (HRV) , and then take blood sample to measure blood routine, immune globulin, complement, sub-T lymphocyte, catecholamines and acetylcholine. These measurements were performed before and after the 8-week’s intervening duration. [Results] The plasma immune globulin, complement, catecholamines and acetylcholine have no significant difference between two groups. But when it came to lymphocyte in peripheral blood, the women in exercising group have less CD8+ T-lymphocyte and higher rate of CD4+/CD8+ than sedentary group. The analysis of HRV showed an increasing total HRV (TF), a enhanced activity of parasympathetic nerve (RRmean, SDNN, RMSSD, HFnorm) and an attenuated activity of sympathetic nerve (LFnorm) in Ba-Duan-Jin exercising group. Correlation analysis confirmed that there is a close relationship between immune function and autonomic nervous activities. [Conclusion] Ba-Duan-Jin can transfer the autonomic nervous balance to parasympathetic dominance, which may partially explain the increasing immunity function (especially in cell immunity) in ageing people.

A Critical Review for the Possibility of Science without ‘Eppue Si Muove’: From Thomas Kuhn’s Theory of Science to Psychology of Science

The theory of science that Thomas Kuhn built in the Structure of Scientific Revolutions was considered as a hypothetical framework in this study. Since the publication of the work, many questions have arisen that call for a psychology of science. These questions are moved to another dimension through the knowledge of the decision made within Galileo Affair, which occupies an important place in modern science, fundamentally arising from an epistemic struggle and emerging out of an unscientific base rather than the charge of unholiness. Abandoning the perspective which evaluates these questions within a historical process as a weak side of the Kuhnian theory of science, this study challenges the current approaches with an alternative approach. The epistemic complexity in the Kuhnian theory of science is an imperative complexity caused by human factors. From this perspective, there are potential questions for psychology of science as a field of study based on Kuhnian epistemology and it can be assumed that new problems may appear when the other epistemological questions which assumed as “answered” are reviewed in the scope of this study. The main thesis of this study is that psychology of science is possible as a valid and operationalizable research program based on Kuhnian theory of science

NQO1 targeting prodrug triggers innate sensing to overcome checkpoint blockade resistance

Lack of proper innate sensing inside tumor microenvironment (TME) limits T cell-targeted immunotherapy. NAD(P)H:quinone oxidoreductase 1 (NQO1) is highly enriched in multiple tumor types and has emerged as a promising target for direct tumor-killing. Here, we demonstrate that NQO1-targeting prodrug β-lapachone triggers tumor-selective innate sensing leading to T cell-dependent tumor control. β-Lapachone is catalyzed and bioactivated by NQO1 to generate ROS in NQO1high tumor cells triggering oxidative stress and release of the damage signals for innate sensing. β-Lapachone-induced high mobility group box 1 (HMGB1) release activates the host TLR4/MyD88/type I interferon pathway and Batf3 dendritic cell-dependent cross-priming to bridge innate and adaptive immune responses against the tumor. Furthermore, targeting NQO1 is very potent to trigger innate sensing for T cell re-activation to overcome checkpoint blockade resistance in well-established tumors. Our study reveals that targeting NQO1 potently triggers innate sensing within TME that synergizes with immunotherapy to overcome adaptive resistance

La valorisation des ressources locales : une voie de développement économique, respectueuse de l'environnement et des sociétés. Le cas du sel de Bandrélé

Les zones insulaires possèdent de nombreuses ressources spécifiques, parfois faiblement valorisées, pouvant aboutir à leur extinction progressive et définitive : pertes de savoirs et savoir faire détenus par des "vieux" et non transmis aux nouvelles générations, perte de biodiversité. Ces ressources, quelles soient biologiques, naturelles, culturelles, sociales, ..., représentent un capital important et engendrent de la territorialité (sentiment d'appartenance à un territoire : Tizon, 1996). Leur activation peut contribuer au développement durable des territoires, à condition qu'elles s'inscrivent dans une démarche raisonnée. En agroalimentaire, cette démarche implique la prise en compte des relations homme - produit - territoire (social - économique - environnement) où l'homme valorise au mieux les spécificités du territoire en mettant en oeuvre des savoirs particuliers. Cette démarche aboutit à des produits à forte spécificité territoriale (typicité) qui permettent en retour la valorisation des hommes (reconnaissance des savoirs faire, de la culture) et du territoire (renforcement de son attractivité). Une telle démarche de développement, collective, s'inscrit sur le long terme et est source de richesses sociales et économiques d'autant plus importantes que les produits et services proposés sur le territoire y sont fortement ancrés et de qualité, et que l'environnement est préservé. L'image territoriale engendrée profite alors au développement touristique, réalisé dans une logique de préservation de la ressource

Records of frugivorous fruit flies (Diptera: Tephritidae; Dacini) from the Comoro archipelago

This paper summarizes current knowledge of the occurrence of Dacini fruit flies in the Comoro archipelago of the Indian Ocean. Ten species are confirmed as occurring in the archipelago: Bactrocera invadens Drew, Tsuruta & White, 2005, Dacus bivittatus (Bigot, 1858), D. ciliatus Loew, 1862, D. etiennellus Munro, 1984, D. punctatifrons Karsch, 1887, D. vertebratus Bezzi, 1908 (all Dacina), Ceratitis capitata (Wiedemann, 1824), C. malgassa Munro, 1939, Neoceratitis cyanescens (Bezzi, 1923), and Trirhithrum nigerrimum (Bezzi, 1913) (all Ceratitidina). Records of Bactrocera cucurbitae (Coquillett, 1899) remain unconfirmed. The fauna of the Comoros is briefly compared to that of other islands in the western Indian Ocean. (Résumé d'auteur

Thickness and structure of thin films determined by background analysis in hard X-ray photoelectron spectroscopy

We report on the analysis of inelastic backgrounds associated with photoelectron peaks from thin films of Ru on Si using hard X-ray photoelectron spectroscopy (HAXPES) with an X-ray energy of 7939 eV. To extract information on the thickness and morphology of the Ru films, the Tougaard-background-analysis method was used. Consistent results from the analysis of the Si 1s peaks as well as the Ru 2p, 2s peaks to the thicknesses determined with X-ray reflectivity were found. Good agreement was also found for surface topography (the Ru forms islands on the Si surface for film thicknesses &lt;12 nm and covers the complete surface for larger thicknesses) determined by our fitting results and scanning electron microscopy. It is demonstrated that with this method it is possible to obtain information on films up to 150 nm thickness, which corresponds to ∼20 times the inelastic mean free paths (IMFPs). This is larger than the previously reported ∼10 times the IMFP for X-ray photoelectron spectroscopy with conventional X-ray sources owing to the fact that the spectrum can be followed over a larger range of energy-loss. The method can also be used to determine the IMFP if the film thickness is known by another technique and it was applied to determine the IMFP for Ru at 4900 eV (4.3 nm) and 6050 eV (5.3 nm). In addition, some possible applications of the methods are described.</p

How to Educate Entrepreneurs?

Entrepreneurship education has two purposes: To improve students’ entrepreneurial skills and to provide impetus to those suited to entrepreneurship while discouraging the rest. While entrepreneurship education helps students to make a vocational decision its effects may conflict for those not suited to entrepreneurship. This study shows that vocational and the skill formation effects of entrepreneurship education can be identified empirically by drawing on the Theory of Planned Behavior. This is embedded in a structural equation model which we estimate and test using a robust 2SLS estimator. We find that the attitudinal factors posited by the Theory of Planned Behavior are positively correlated with students’ entrepreneurial intentions. While conflicting effects of vocational and skill directed course content are observed in some individuals, overall these types of content are complements. This finding contradicts previous results in the literature. We reconcile the conflicting findings and discuss implications for the design of entrepreneurship courses
