Contour map of the top of the regional geothermal reservoir of Sicily (Italy).
2015
An integrated review of existing geological and geophysical data – partly acquired during oil and gas exploration – combined with new data provided by deep geothermal studies of selected key areas, was used for the 3D modeling and mapping of the top of the geothermal reservoir developed at a regional scale in Sicily (Central Mediterranean). The resulting 1:500,000 scale map covers the area of the whole Sicily (about 25,700 km2) and is devoted to represent the main input for both the thermal modeling and the evaluation of geothermal potential at a regional scale. As the map indicates the distribution at depth of a likely target for geothermal drilling, it can be also used as a rough indicato…
Fosildiagénesis del anélido Rotularia spirulaea (Lamarck, 1818) (Polychaeta, Serpulidae) en el Eoceno del dominio pirenaico occidental
2018
The presence of the fossil polychaete Rotularia spirulaea (Lamarck, 1818) in Eocene deposits (middle Lutecian – upper Bartonian and (?) Priabonian) belonging to the western Pyrenean Domain is verified. In this paper, a fossildiagenetic study has been carried out. Fossils from three areas, corresponding to diff erent depositional settings, have been analysed. In area 1, sediments of the Ardanatz Sandstone and Ilundain Marls formations [Pamplona Basin and adjoining areas (Navarre)], were sampled. Here, the specimens of R. spirulaea were not substantially affected by taphonomic reworking and the original microstructure of the carbonate tube is preserved. The test consists of a thick external …
Partially disarticulated new Miocene burrower bug (Hemiptera: Heteroptera: Cydnidae) from Cerová (Slovakia) documents occasional preservation of terr…
2015
The state of preservation of the bug Sehirus carpathiensis J.A. Lis, Vršanský & Schlögl, sp. n. (Hemiptera: Heteroptera: Cydnidae) from the Lakšárska Nová Ves Formation at Cerová (Slovakia) supports extremely rapid sinking and burial in upper bathyal Early Miocene sediments. The specimen originated from land at most a few kilometers away, but transport via a river can be excluded as the head and wings are still attached. Its most likely source based on fossil flora and the habitat of several living representatives of the genus is a riparian habitat in an adjacent area of land. Phylogenetically the new species is closely related to both Oligocene and living representatives of the genus, thus…
Laudun-l'Ardoise (30), Excoutellier
2021
Le diagnostic de l’Excoutellier a permis de confirmer la présence d’un site protohistorique pointé dans les années 1990 par les prospections menées par le groupe archéologique de la vallée de La Tave et coordonnées par Hervé Petitot. Installée sur le flanc sud-ouest du plateau de Lacau, cette occupation de bas de pente se caractérise par quelques aménagements fossoyés associés à des structures de combustion. Un mobilier relativement riche (plus de 1600 fr. de céramique) permet d’envisager une mise en place de l’occupation à la toute fin de l’âge du Bronze, occupation qui dure probablement jusqu’aux premiers temps de l’âge du Fer. Malgré la mise en terrasses du secteur à la période moderne, …
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
Les traces de pas d'amphibiens, de dinosaures et autres reptiles du Mésozoïque français: inventaire et interprétations.
2007
Since the 19th century, thousands of footprints were observed in the geological series of the French Mesozoic. All are located in the Triassic and Jurassic. After a promising beginning, in France, it is only a few papers which will be published in the first half 20th century, unlike the USA and of others countries of Western Europe. One ought to wait about 1950 for a revival and now they are nearly 200 papers which were devoted to the ichnofossils. The literature abundance and the renewed interest of the naturalists for the palichnologic studies decided to us to write a synthesis work. This one begins with a stratigraphic inventory in which, localisation, age and paleontological contents of…
il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi
2014
riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …
La Tene human burial and animal deposit at Varennes-sur-Seine (Seine-et-Marne)
2002
An adolescent was buried at the bottom of a large irregular shaped pit The body that had been lain on one side, legs tucked under, was in the centre of a ring of stones and was covered by a deposit of a dog and four horses of which two were foals and two were young adults. A thick layer of sand and a second deposit of three horses and a dog covered this first deposit. The adolescent skull had been broken and perforated which adds to the distinctiveness of this burial. Most of the horses had been skinned and the tendons had been removed. Also the four legs of one of the horses in the top deposit had been removed. With no datable finds the radiocarbon analysis gives a date corresponding to th…
Occitanie, Haute-Garonne, Grenade, Le Castelet
2019
Le lieu-dit Le Castelet à Grenade (Haute-Garonne) est situé à égale distance (1,5 km) du confluent Hers-Girou vers l’est et d’un méandre de la Garonne vers le nord-ouest. Un projet de carrière de la Société Midi-Pyrénées Granulats a permis de retrouver dans ce lieu les traces de plusieurs occupations humaines, échelonnées pour l’essentiel entre le Néolithique moyen et de la fin de l’âge du Bronze. L’ancien réseau hydrographique secondaire de la Garonne marque le paysage et draine dans le sous-sol la nappe phréatique, constituant sans doute un atout. En effet, il suffit de creuser un puits au sein d’un paléo-chenal pour créer un point d’eau au milieu d’une plaine cultivable, et réunir ainsi …
