Avènement des sports nautiques à Chalon-sur-Saône (1877-1960)
2002
RESUME En France, l’evolution vers le sport, au sens moderne du terme, s’effectue a travers un long processus qui prend ses racines dans les annees 1870 et s’acheve au milieu du XXeme siecle. A partir de 1877, differentes societes d’activites nautiques sont fondees a Chalon-sur-Saone et mettent en place la pratique de la natation, des joutes et des regates. Des points communs, des relations d’interdependance mais aussi des contrastes importants dans leurs caracteristiques, permettent de les assimiler a un systeme local d’associations. L’etude du developpement de ce systeme, confronte a la modernisation de la societe et du monde des activites physiques, illustre la diversite des modalites d’…
Evaluation of Green Roof Ageing Effects on Substrate Hydraulic Characteristics
2020
The vegetated substrate of green roofs may undergo various chemical and physical changes with time. Minidisk infiltrometer (MDI) tests were conducted to assess the short-term variations of the near-saturated hydraulic conductivity, K0, in the extensive green roof test plot established at the University of Palermo. Sampling was repeated four times: before planting (Age 0) and then after four months (Age 1), seven months (Age 2) and ten months (Age 3). A total of 144 infiltration tests were conducted at two pressure heads, h0 = −3 cm and h0 = −0.5 cm and infiltration data analysed by the Zhang (Soil Science Society of America Journal 61(4):1024–1030, 1997) model. Both K-3 and K-0.5 underwent …
Transient soil-moisture dynamics and climate change in Mediterranean ecosystems
2008
[1] Plants in Mediterranean ecosystems have developed different strategies to cope with transient soil-moisture dynamics induced by the markedly out of phase seasonal behavior of rainfall and temperature. Deep-rooted plants use the soil moisture stored in the wet winter (extensive users), while shallower rooted plants exploit both the wet season storage and the more sporadic growing season rainfall (intensive users). Using stochastic models of soil-moisture dynamics, we present an analytical and numerical description of the probabilistic structure of the soil-moisture storage at the beginning of the growing season in relation to the dynamics of the wet season and then study its evolution du…
Determining water use of sorghum from two-source energy balance and radiometric temperatures
2011
Estimates of surface actual evapotranspiration (ET) can assist in predicting crop water requirements. An alternative to the traditional crop-coefficient methods are the energy balance models. The objective of this research was to show how surface temperature observations can be used, together with a two-source energy balance model, to determine crop water use throughout the different phenological stages of a crop grown. Radiometric temperatures were collected in a sorghum (<i>Sorghum bicolor</i>) field as part of an experimental campaign carried out in Barrax, Spain, during the 2010 summer growing season. Performance of the Simplified Two-Source Energy Balance (STSEB) model was …

Poetics of the "savage" : practice of tattooing in the modern world
2012
Ancient as it may be the popularity for tattoo does not seem to wane in the West. Indeed, we can find a great number of tattoo studios, exhibitions or magazines in our cities. The iconography of the brand seems to be the result of an amazing syncretism of which the "wild" imagery is an important part. Maori tattoos, Arabic calligraphy, dragons and wild animals, not from Western culture, are indeed very popular patterns. True mode of expressions of the skin, the ethnic tattoo indicates a certain view of the world, a view of the Other, as the path one chooses to follow in order to search for a "sense of self". Since the cabinets of curiosities of the sixteenth century, the Western world colle…
Probable disseminated Mycobacterium abscessus subspecies bolletii infection in a patient with idiopathic CD4+ T lymphocytopenia: a case report.
2012
Abstract Introduction Rapidly growing mycobacteria are opportunistic pathogens in patients with underlying risk factors. Mycobacterium abscessus subsp. bolletii is a newly recognized member of rapidly growing mycobacteria, isolated from respiratory tract and cutaneous infections. Case presentation We describe a case of chronic disseminated infection caused by M. abscessus subsp. bolletii in a 38-year-old Sri Lankan man with idiopathic CD4+ T lymphocytopenia. Idiopathic CD4+ T lymphocytopenia is a rare cause of immunodysfunction that, similar to human immunodeficiency virus infection, causes a depletion of CD4+ T lymphocytes. M. abscessus subsp. bolletii infection was diagnosed by culture is…
Relation between anaerobic power and rowing ergometer performance in young rowers
2013
Aims: Rowing performance over 2000m is dependent upon the functional capacity of both the aerobic and anaerobic energy pathways. Although several studies have indicated that maximal oxygen uptake is strongly related to rowing performance and it is the best predictor of performance in elite rowers, some evidence is that muscle power output could be an important predictor of performance. The aim of this study was to investigate the possible relationship between anaerobic power and rowing ergometer performance over 2000m in young rowers, and whether anaerobic power assessed could identify athletes with the best performance. Methods: We collected biometric characteristics and energy data, inclu…
<title>Combining multiple image descriptions for browsing and retrieval</title>
2000
Retrieving images form large collections using image content is an important problem, in this multimedia age. A quick content-based visual access to the stored image is capital for efficient navigation through image collections. In this paper we introduce several techniques which characterize color homogeneous object and their spatial relationships for efficient content-based image retrieval. We present a region growing technique for efficient color homogeneous objects segmentation and extend the 2D string to an accurate description of spatial information and relationships. In order to improve content-based image retrieval, our method emphasized several objectives, such as: automated extrac…
