RĂ©gĂ©nĂ©rer efficacement les peuplements de pin : des travaux souvent indispensables ! Lâexemple des peuplements Ă pin dâAlep en zone mĂ©diterranĂ©enne
La rĂ©gĂ©nĂ©ration naturelle est souvent un phase critique de la vie des peuplements forestiers, notamment pour les peuplements anciens et les espĂšces pionniĂšres. Câest ainsi le cas des vieilles pinĂšdes Ă pin dâAlep en zone mĂ©diterranĂ©enne. Dans cet article, les auteurs testent lâimpact de diverses perturbations de la vĂ©gĂ©tation et du sol qui peuvent influer sur cette rĂ©gĂ©nĂ©ration. Cette Ă©tude montre lâimportance des travaux sylvicoles pour le renouvellement des peuplements
Régénération du pin d'Alep en Basse Provence. Impact des traitements du sol, de la végétation et des rémanents
Le pin d'Alep est une essence pionniÚre majeure des régions méditerranéennes.
Elle permet une reconquĂȘte des milieux aprĂšs incendie ou sur les terres abandonnĂ©es. Cependant, sa rĂ©gĂ©nĂ©ration, une fois les peuplements installĂ©s et vieillissants, pose problĂšme. Cet article prĂ©sente les rĂ©sultats de l'impact de diffĂ©rents traitements de la vĂ©gĂ©tation, du sol et des rĂ©manents sur la rĂ©gĂ©nĂ©ration du pin d'Alep
Installer des semis de chĂȘnes dans les pinĂšdes Ă pin d'Alep en phase de renouvellement -
Les peuplements mélangés possÚdent de nombreux avantages, dont celui de présenter ne meilleure résilience face à des perturbations telles que les incendies, mais aussi les perturbations climatiques. La phase de régénération naturelle, avec plusieurs essences, représente donc une étape clé dans la vie du peuplement et pour son avenir. Cette étude décrit l'installation de glands dans une pinÚde en cours de renouvellement, selon divers traitements du sol et de la végétatio
Social sciences research in neglected tropical diseases 2: A bibliographic analysis
The official published version of the article can be found at the link below.Background
There are strong arguments for social science and interdisciplinary research in the neglected tropical diseases. These diseases represent a rich and dynamic interplay between vector, host, and pathogen which occurs within social, physical and biological contexts. The overwhelming sense, however, is that neglected tropical diseases research is a biomedical endeavour largely excluding the social sciences. The purpose of this review is to provide a baseline for discussing the quantum and nature of the science that is being conducted, and the extent to which the social sciences are a part of that.
Methods
A bibliographic analysis was conducted of neglected tropical diseases related research papers published over the past 10 years in biomedical and social sciences. The analysis had textual and bibliometric facets, and focussed on chikungunya, dengue, visceral leishmaniasis, and onchocerciasis.
Results
There is substantial variation in the number of publications associated with each disease. The proportion of the research that is social science based appears remarkably consistent (<4%). A textual analysis, however, reveals a degree of misclassification by the abstracting service where a surprising proportion of the "social sciences" research was pure clinical research. Much of the social sciences research also tends to be "hand maiden" research focused on the implementation of biomedical solutions.
Conclusion
There is little evidence that scientists pay any attention to the complex social, cultural, biological, and environmental dynamic involved in human pathogenesis. There is little investigator driven social science and a poor presence of interdisciplinary science. The research needs more sophisticated funders and priority setters who are not beguiled by uncritical biomedical promises
Performance studies of the final prototype for the CASTOR forward calorimeter at the CMS experiment
We present performance results of the final prototype for the CASTOR quartz-tungsten sampling calorimeter, to be installed in the very forward region of the CMS experiment at the LHC. The energy linearity and resolution, the uniformity, as well as the spatial resolution of the prototype to electromagnetic and hadronic showers are studied with 10--200 GeV electrons, 20--350 GeV pions, and 50, 150 GeV muons in beam tests carried out at CERN/SPS in 2007
