2017
Saint-Martin-sous-Montaigu located in the "Cote Chalonnaise" in Burgundy, is an important place for the archaelogy of the Paleolithic period. This report present the geological context of this area and the geomorphological evolution of the Vallée des Vaux.

La cueva de El Sidrón (Borines, Piloña, Asturias): primeros resultados
2003
Se exponen los resultados preliminares de las excavaciones arqueológicas llevadas a cabo en la Cueva de El Sidrón entre 2000 y 2002, de acuerdo con los tres objetivos principales que conciernen al registro fósil humano: las características antropológicas, cómo y cuándo llegaron allí y la relación entre fósiles y cultura. Las primeras conclusiones obtenidas son que los restos humanos pertenecen al Neandertal, que el registro arqueológico corresponde a un tecno-complejo del Paleolítico Medio y que están en posición secundaria
The use of shallow dripwater as an isotopic marker of seepage in karst areas: A comparison between Western Sicily (Italy) and the Harz Mountains (Ger…
2013
Abstract The isotopic signature of slow-flowing dripwater collected in caves located in Western Sicily (Italy) was determined for evaluating its possible use as an isotopic tracer of the local groundwater recharge. These spot measures were compared with a longer series of local rain and spring compositions and with other samples taken, under different hydrogeological conditions, in caves of the Harz Mountains (Northern Germany). The slow flowing dripwater from Sicily showed δ 18 O/δD ratios similar to those of local rain and groundwater, demonstrating that these three are all parent waters. A parallel similarity was found in the vertical isotopic gradient (Δδ 18 O) of the three groups of wa…

Sztuczna mucha i czysta gra. Wędkarstwo jako dystynktywna praktyka kulturowa
2019
Artykuł jest próbą przedstawienia wędkarstwa jako praktyki kulturowej o społecznie – w zasadzie głównie klasowo – różnicującym potencjale. Szczególnie pod tym względem interesujący i znaczący jest przypadek tak zwanej sztucznej muchy – metody, która stanowi wysoce skodyfikowany kulturowo obszar społecznie dystynktywnych znaczeń i działań. Artykuł w głównej mierze odnosi się do faktów poświadczonych dla XIX wieku, kiedy to tworzyły się podstawowe reguły muszkarstwa, które bądź to w postaci zinstytucjonalizowanej, bądź poprzez nieformalne ramy kształtowały prawomocne praktyki sportowego łowienia ryb szlachetnych.
Framing w procesie zarządzania informacją w dziennikarstwie
2013
Information management plays an extremely important role in journalism, mainly because journalists are autonomous in selecting and prioritizing topics. Walter Gieber wrote: “News is what newspapermen make it,” emphasizing the omnipotence of journalists and editors in the process of selecting information, primarily in the context of journalism winning or losing its credibility. One of the instruments of control over the contents of communication in the media is framing. This is an important tool used in editorial work, to predict the life of a media event. The article is an attempt to outline the relationship between framing and management of information in modern journalism.
Preliminary geochemical characterization of the Mts. Simbruini karst aquifer (Central Italy)
2021
Mts. Simbruini karst aquifer feeds important springs whose capture contributes to the water supply of Rome City. To improve the geochemical characterization of this aquifer, we analyzed 36 groundwater samples, 29 from springs and 7 from shallow wells, collected in 1996 and 2019. Atomic adsorption spectroscopy, tritration, ionic chromatography and mass spectrometry were the used analytical methods. Ground waters are bicarbonate alkaline-earth type and HCO3 dominance confirms that the aquifer is hosted in carbonate rocks. Total alkalinity vs. cations plot indicates that CO2 driven weathering controls the water chemistry. The probability plots of HCO3, cations and Ca2+ +Mg2+ indicate four grou…
Solution and recrystallisation processes and associated landforms in gypsum outcrops of Sicily
2003
Abstract Four small areas of Messinian (Upper Miocene) age gypsum, outcropping in western Sicily, are described. Messinian age evaporites are found in Sicily over a 1000-km 2 area. Here, gypsum outcrops extensively as a consequence of soil erosion induced by human impact. Geomorphological maps show how the rocky surfaces are characterized by a wide range of forms. There are large, medium, small, and microsized forms, which can be identified as belonging to different morphotypes. The morphotypes can be classified into two main categories: those that originated by solution and those that originated through recrystallisation. Four areas, illustrated by geomorphological maps, were specifically …
Structural control on the presence and character of calas: Observations from Balearic Islands limestones rock coast macroforms
2013
Calas are characteristic embayed rocky coastline landforms related to steep-sided drowned valleys that were deeply incised during low sea-level stages into carbonate plateaus. This paper studies the factors that control the presence and character of calas in three different islands of the Balearic Archipelago (Mallorca, Menorca and Formentera) by means of Digital Elevation Model (DEM) reconstructions, embayment and catchment morphometric analysis and through the compilation of fault and joint orientations. All islands exhibit emerged carbonate platforms (Upper Miocene in age) characterised by horizontal or very gently-dipping bedding. Two distinct patterns observed at all study sites are th…
