A giant planet beyond the snow line in microlensing event OGLE-2011-BLG-0251
2013
We present the analysis of the gravitational microlensing event OGLE-2011-BLG-0251. This anomalous event was observed by several survey and follow-up collaborations conducting microlensing observations towards the Galactic Bulge. Based on detailed modelling of the observed light curve, we find that the lens is composed of two masses with a mass ratio q=1.9 x 10^-3. Thanks to our detection of higher-order effects on the light curve due to the Earth's orbital motion and the finite size of source, we are able to measure the mass and distance to the lens unambiguously. We find that the lens is made up of a planet of mass 0.53 +- 0.21,M_Jup orbiting an M dwarf host star with a mass of 0.26 +- 0.…
Normatywne kształtowanie terenów zieleni w mieście podstawą budowania zrównoważonych miast
2021
Tereny zieleni w mieście są istotnym zagadnieniem w kształtowaniu struktury funkcjonalno-przestrzennej miasta, a także kształtowania jego rozwoju w sposób zrównoważony. W literaturze przedmiotu zwraca się uwagę na konieczność dążenia do równowagi między celami społecznymi, ekologicznymi i ekonomicznymi, które powinny być definiowane w polityce rozwoju jednostek terytorialnych różnych szczebli, w tym także miast. Istotne jest również zachowanie równości międzypokoleniowej m.in. poprzez zachowanie zasobów środowiska (Fiedor, 2002,s. 23). J. Słodczyk zwraca uwagę, że w realizacji koncepcji miasta zrównoważonego istotne są takie zagadnienia jak m.in. forma przestrzenna miasta, proekologiczne ro…
Low-temperature single crystal X-ray diffraction and high-pressure Raman studies on [(CH3)2NH2]2[SbCl5]
2007
The structure of bis(dimethylammonium) pentachloroantimonate(III), [(CH{sub 3}){sub 2}NH{sub 2}]{sub 2}[SbCl{sub 5}], BDP, was studied at 15 K and ambient pressure by single-crystal X-ray diffraction as well as at ambient temperature and high pressures up to 4.87(5) GPa by Raman spectroscopy. BDP crystallizes in the orthorhombic Pnma space group with a=8.4069(4), b=11.7973(7), c=14.8496(7) A, and Z=4; R{sub 1}=0.0381, wR{sub 2}=0.0764. The structure consists of distorted [SbCl{sub 6}]{sup 3-} octahedra forming zig-zag [{l_brace}SbCl{sub 5}{r_brace}{sub n}]{sup 2n-} chains that are cross-linked by dimethylammonium [(CH{sub 3}){sub 2}NH{sub 2}]{sup +} cations. The organic and inorganic substr…
The Hamburg/ESO R-process Enhanced Star survey (HERES)
2004
We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe] > 1 dex; hereafter r-II stars), the Hamburg/ESO R-process Enhanced Star survey (HERES). Moderate-resolution (~2A) follow-up spectroscopy has been obtained for metal-poor giant candidates selected from the Hamburg/ESO objective-prism survey (HES) as well as the HK survey to identify sharp-lined stars with [Fe/H] < -2.5dex. For several hundred confirmed metal-poor giants brighter than B~16.5mag (most of them from the HES), ``snapshot'' spectra (R~20,000; S/N~30 per pixel) are being obtained with VLT/UVES, with the main aim of finding the 2-3% r-II stars expected to be a…
L'accès des ménages aux services dans l'espace périurbain francilien
2008
The access of populations to services, out of the dense urban centres, is marked by the retreat of the services of proximity to which populations and local councillors appear particularly attached. However, in peri-urban spaces, this remote setting of the resources compared to the populations is the result of the generalized adoption of the automobile standard for mobility and accessibility. That has two effects: first a disintegration of the local offer, then a disintegration of the modal alternatives to the private car, because of relocalizations of services and populations which privilege car for their accessibility and call into question their access by other modes like public transport…
Spatial representations of future in Homeric Greek
2015
The aim of this paper is to investigate the space-time mapping of the future in Homeric Greek. It is widely accepted that the spatial adverbs πρόσσω ‘in front’ and ὀπίσσω ‘behind’ in the Homeric poems are used to portray temporal events located in a sequence of aligned entities that follow one after the other on the same path (Dunkel, 1983, p. 66). In such a temporal sequence, or Time-rp model, those adverbs are associated respectively to past and future events in a bipartite spatial representation of time, without involving a deictic ego-experiencer. After analyzing data from the Homeric poems in a cognitive linguistic perspective, it is found that some temporal uses of the preposition πρό…
Spaces, (Non-)Places, and Fluid Identities in Tim Winton’s Fiction
2021
One of the major issues addressed by postcolonial literature is identity crisis. In Australia, a multicultural country and a former settler colony, where the sense of belonging is particularly troubling, this literary theme has been exploited by writers to address the ambiguity of home and belonging. This article attempts to examine Tim Winton’s fiction and show how the writer explores the concepts of place and space to set his protagonists’ shattered selves in the postcolonial geography. The analysis of his fiction from the perspective of humanistic geography, Edward Relph’s concept of placelessness, and Marc Auge’s idea of non-place reveals that a simple categorization of Winton’s setting…

L’effet des pots acoustiques du caveau phonocamptique de la cathédrale de Noyon : analyse modale et performance chantée
2016
International audience; Au CFA de 2014 nous présentions le caveau phonocamptique de la Cathédrale de Noyon qui comporte, dans un espace souterrain réduit (15 m²), un nombre important de pots acoustiques (64). L’étude des livres liturgiques et de la documentation de la cathédrale (XVe-XVIIe siècles) ne permet pas à ce jour d’identifier le rôle et l’usage de ce caveau. Pourtant, les études archéologiques et acoustiques que nous avions présentées en 2014 montraient le soin qu’avaient pris les bâtisseurs pour élaborer cet espace : deux modèles de pots de hauteurs différentes, correspondant à deux fréquences moyennes proches d’une quarte musicale, une répartition choisie dans l’espace et un trav…
