Monitoring temporal opacity fluctuations of large structures with muon tomography : a calibration experiment using a water tower tank

Usage of secondary cosmic muons to image the geological structures density distribution significantly developed during the past ten years. Recent applications demonstrate the method interest to monitor magma ascent and volcanic gas movements inside volcanoes. Muon radiography could be used to monitor density variations in aquifers and the critical zone in the near surface. However, the time resolution achievable by muon radiography monitoring remains poorly studied. It is biased by fluctuation sources exterior to the target, and statistically affected by the limited number of particles detected during the experiment. The present study documents these two issues within a simple and well constrained experimental context: a water tower. We use the data to discuss the influence of atmospheric variability that perturbs the signal, and propose correction formulas to extract the muon flux variations related to the water level changes. Statistical developments establish the feasibility domain of muon radiography monitoring as a function of target thickness (i.e. opacity). Objects with a thickness comprised between $\simeq$ 50 $\pm$ 30m water equivalent correspond to the best time resolution. Thinner objects have a degraded time resolution that strongly depends on the zenith angle, whereas thicker objects (like volcanoes) time resolution does not.Comment: 11 pages, 9 figures.

Regenerating conflicted landscapes in post-war El Salvador: livelihoods, land policy, and land use change in the Cinquera Forest

This paper charts events that transpired in the spaces between the larger forces that shaped El Salvador's transition from war to peace throughout the 1990s to the present day and tells the story of one place with entwined histories of forests growth, new land rights that were born of peace, and livelihoods being imagined and crafted from both. Over the six years following the signing of the peace Accords in 1992, ten percent of the nation's agricultural land (totaling over 103,300 hectares) was transferred to ex-combatants of both sides and to civilian supporters of the FMLN, through the Accord-mandated Land Transfer Program. By the year 2000, more than 36,000 people had received land through the PTT and an additional program had been created to parcelize and individually title all PTT lands that were formerly deeded collectively. While leaders of both the FMLN and the government set out to influence the post-war social and political landscape and the donor community generated post-war reconstruction projects, a group of ex-combatants, refugees, and displaced returning to the community of Cinquera, department of Cabañas, proceeded to take the land deeded to them as part of the Peace Accords. They subsequently transformed its use and value in ways never foreseen or intended by government land reform officials, FMLN party organizers, or international aid donors. In the process of linking their history to their future, the people of Cinquera created spaces of habitation for themselves and the natural world. To us, they offer a lesson in how a small community's continued struggle to live out their intentions for an alternative society, act by act, may in the end prove the best possible way to negotiate a revolution.

Jean-Yves Hameline, Petite poétique des arts sacrés

L’ouvrage met à la disposition du public trente-deux articles de Jean-Yves Hameline (†), qui fut professeur à l’Institut catholique de Paris en liturgie et anthropologie des rites. Ces articles brefs ont été publiés dans différentes revues de 1978 à 2007, et on sait gré à l’éditeur de les mettre ainsi à la disposition du public. Hameline était prêtre et théologien, et son travail sous un angle anthropologique porte la marque de son engagement. L’approche que révèlent ces courtes études est en..

Bernard Piettre, François Vouga, La Dette. Enquête philosophique, théologique et biblique sur un mécanisme paradoxal

Écrit à quatre mains par un philosophe et un bibliste, ce livre s’efforce de réinscrire la question de la dette, au sens le plus large qui soit, dans la tradition biblique du Nouveau Testament. Il ne prétend pas refaire ni compléter le travail que David Graeber a publié sur l’anthropologie de la dette (La dette. 5 000 ans d’histoire, 2013), mais simplement développer la dimension éthique proposée par le Nouveau Testament et le christianisme social. Selon les auteurs, qui alternent leurs inter..

Avec ou sans Dieu ? Le philosophe et le théologien

Pourquoi le « religieux » fascine-t-il le philosophe agnostique ? Question posée en ouverture de l’ouvrage par le théologien Claude Geffré à Régis Debray. La floraison continue de mouvements de spiritualité, particulièrement aux États-Unis, pays de la modernité la plus emblématique, ne cesse de mettre en question les Européens travaillés par un certain évanouissement de la question religieuse. Le rôle du christianisme est décisif : les deux auteurs s’accordent sur ce point, tout en différenci..
