In this study, a new method has been developed to produce pure crystalline BaZrO3 powders from Ba+Zr solution or weakly soluble reactants by using precipitation route in highly basic aqueous solution. The influence of several synthesis parameters is studied. At high OH- concentration ([NaOH] = 20 mol/l), it is possible to obtain the well-crystallized stoichiometric perovskite phase at relatively low temperature (~80°C), after a short reaction time (15 minutes) and without requiring any precaution to avoid the presence of CO2. This synthesis method yields spherical particles, whose size can be controlled by changing the concentration of the Ba+Zr solution. No calcination treatment is necessary since the precipitate is crystalline. Suitable choice of the synthesis parameters ([NaOH] = 20 mol/l, [Ba+Zr] = 1 mol/l, reaction time = 15 minutes) yields a sub-micron precipitate. [less ▲]

Knowledge and technology transfer to African institutes is an important objective to help achieve the United Nations Millennium Development Goals. Plant biotechnology in particular enables innovative advances in agriculture and industry, offering new prospects to promote the integration and dissemination of improved crops and their derivatives from developing countries into local markets and the global economy. There is also the need to broaden our knowledge and understanding of cassava as a staple food crop. Cassava (Manihot esculenta Crantz) is a vital source of calories for approximately 500 million people living in developing countries. Unfortunately, it is subject to numerous biotic and abiotic stresses that impact on production, consumption, marketability and also local and country economics. To date, improvements to cassava have been led via conventional plant breeding programmes, but with advances in molecular-assisted breeding and plant biotechnology new tools are being developed to hasten the generation of improved farmer-preferred cultivars. In this review, we report on the current constraints to cassava production and knowledge acquisition in Africa, including a case study discussing the opportunities and challenges of a technology transfer programme established between the Mikocheni Agricultural Research Institute in Tanzania and Europe-based researchers. The establishment of cassava biotechnology platform(s) should promote research capabilities in African institutions and allow scientists autonomy to adapt cassava to suit local agro-ecosystems, ultimately serving to develop a sustainable biotechnology infrastructure in African countries.

More than 250 million Africans rely on the starchy root crop cassava (Manihot esculenta) as their staple source of calories. A typical cassava-based diet, however, provides less than 30% of the minimum daily requirement for protein and only 10%-20% of that for iron, zinc, and vitamin A. The BioCassava Plus (BC+) program has employed modern biotechnologies intended to improve the health of Africans through the development and delivery of genetically engineered cassava with increased nutrient (zinc, iron, protein, and vitamin A) levels. Additional traits addressed by BioCassava Plus include increased shelf life, reductions in toxic cyanogenic glycosides to safe levels, and resistance to viral disease. The program also provides incentives for the adoption of biofortified cassava. Proof of concept was achieved for each of the target traits. Results from field trials in Puerto Rico, the first confined field trials in Nigeria to use genetically engineered organisms, and ex ante impact analyses support the efficacy of using transgenic strategies for the biofortification of cassava.

Several factors are likely to control sleeping site selection and presleep behavior in nonhuman primates, including predation risk and location of food resources. We examined the effects of these factors on the sleeping behavior of northern pigtailed macaques (Macaca leonina). While following a troop living in the surroundings of the Visitor Center of Khao Yai National Park (Thailand), we recorded the physical characteristics and location of each sleeping site, tree, the individuals’ place in the tree, posture, and behavior. We collected data for 154 nights between April 2009 and November 2010. The monkeys preferred tall sleeping trees (20.97SD 4.9 m) and high sleeping places (15.87SD 4.3 m), which may be an antipredator strategy. The choice of sleeping trees close to the last (146.77SD 167.9 m) or to the first (150.47SD 113.0 m) feeding tree of the day may save energy and decrease predation risk when monkeys are searching for food. Similarly, the choice of sleeping sites close to human settlements eases the access to human food during periods of fruit scarcity. Finally, the temporal pattern of use of sleeping sites, with a preference for four of the sleeping sites but few reuses during consecutive nights, may be a tradeoff between the need to have several sleeping sites (decreasing detection by predators and travel costs to feeding sites), and the need to sleep in well-known sites (guaranteeing a faster escape in case of predator attack).

The objective of this study was to assess the effect of temperature (5-25°C) on the ‘in vitro’ and ‘in vivo’ growth rates of Penicillium italicum and to determine the combined effect of temperature and relative humidity (45 to 100%) on lesion size of this pathogenic fungus on Valencia late oranges, either alone or in combination with the antagonistic yeast strain Z1 of Pichia guilliermondii Wickerham. Statistical analysis showed a significant effect of temperature on the ‘in vitro’ and ‘in vivo’ radial growth of P. italicum with the maximum growth observed at temperature of 25°C. In both cases, no growth was observed at a temperature of 35°C. These factors had a significant effect on P. italicum lesion size when it was applied alone on Valencia late oranges and insignificant when yeast strain Z1 was applied 24 h before P. italicum inoculation. Our results confirm previous ‘in vitro’ findings that aw has a greater influence than temperature on P. italicum growth and highlight that the strain Z1 showed high antagonistic potential against this pathogen over a range of temperature-relative humidity regimes favouring P. italicum development.

This article presents the first hypotheses and questions developped from a clinical study in the representation of the parental function by lesbian couples asking for Artificial Insemination by Donor (AID). The early French speaking and English speaking reference on the debate on same sex parenthood within the psychoanalytical communities led us to structure our qualitative data analysis (case analysis of thirty two couples around two main issues. First, AID can be seen as an experience which introduces a third person to the lesbian couple and carries an important paradox for the psyche ol all those involved; secondly, it is useful to analyse the psychic developments linkec to access to same sex parenthood, and in particular how subjects construe themselves as biological or social mothers. This two-pronged analysis based on clinical cases actually serves a metapsychological reflection on the concept of psychic bisexuality. as a key element of psychic development for lesbian couples.

Dans l’écriture même du scénario, dans les designs des personnages, dans les références des décors, dans les registres d’animation et dans la mise en scène, Walt Disney a placé intentionnellement des éléments de rhétorique qui permettront à un disours de canonisation de s’instaurer quasi immédiatement au moment de la sortie des films. Cela témoigne bien entendu d’une très grande intelligence de Disney des attentes du public et des institutions (au sens large). Cet article entend détailler cette stratégie d'auto-canonisation.

Le brome épais (Bromus grossus Desf. ex DC.) est une graminée commensale des moissons bien qu'on la trouve occasionnellement en bordure de champs ou dans des terrains en friche. C'est une espèce menacée de disparition dans toute son aire de répartition, raison qui a justifié son inscription à l'annexe II de la Directive 92/43/CEE du Conseil du 21 mai 1992 concernant la conservation des habitats naturels ainsi que de la faune et de la flore sauvages (aussi connue comme la "Directive Habitats"). Cette protection est assurée au niveau wallon par l'inscription de l'espèce à l'annexe VIa du décret du Gouvernement Wallon du 6/12/2001 ; en raison de sa très grande rareté, la Région Wallonne a une responsabilité importante pour sa conservation.

Acne is a domain in which the technology and understanding of light/laser therapeutic procedures have advanced considerably. The aim of the paper was to revisit adjunctive physical treatments of acne, including light/laser treatments and photodynamic therapy. This review summarizes findings about such treatment modalities with particular emphasis on efficacy and safety. A number of laser/light-based modalities have been developed to meet the increasing demand for new acne treatments. The current devices correspond, on the one hand, to light-emitting diode therapy and, on the other hand, to the 532-nm potassium titanyl phosphate laser, the 585- and 595-nm pulsed dye laser, the 1450-nm diode laser, the 1320-nm Nd:YAG laser and intense pulsed light. Photodynamic therapy is also available. It is claimed that light/laser treatments might induce a faster response compared with the 1-3 months needed for response to traditional oral and topical treatments. In conclusion, pulsed dye laser shows efficacy in some patients with mild to moderate acne. The relative effectiveness compared with other treatments is unconfirmed; from the published information, evidence-based efficacy assessment of light/laser therapies in acne remains almost impossible.
