Experimental alteration of granitic rocks: Implications for the evolution of geothermal brines in the Upper Rhine Graben, Germany
2020
Abstract Geothermal energy exploitation in the Upper Rhine Graben (URG) chiefly has targeted faults and fractures within or connected with the crystalline basement, where hot fluids of c. 200 °C circulate at depths of c. 5 km. Formation fluids of the crystalline basement are highly saline, NaCl-dominated brines, whereas shallow crystalline basement water ( The trace element concentrations of the leachates are hereby related to the composition and stability of minerals in the rocks and can be directly linked to the proposed and observed dissolution processes at the different temperatures. In experiments with pure water at 70 °C, representing the recharge or infiltration conditions, water-roc…

La medición de la felicidad en el trabajo y sus antecedentes : un estudio empírico en el area de alergología de los hospitales públicos españoles
2014
La búsqueda de la felicidad en el trabajo es un objetivo de enorme importancia para muchas personas y organizaciones. Sin embargo, existe una carencia importante la investigación acerca de cómo aumentarla (Chivato Pérez et al., 2011), así como una amplia dispersión de medidas relacionadas (Hackman, 2009). No se conoce ninguna medida que recoja con la suficiente amplitud la medición de la felicidad en el trabajo (Fisher, 2010), por lo que en este estudio proponemos un modelo integrativo que nos aporte la medida de este nuevo constructo. Proponemos que la felicidad en el trabajo se compone de tres constructos ya consolidados en la literatura. La primera hipótesis de esta investigación es que …

Geochemical and mineralogical indicators for aqueous processes in the Columbia Hills of Gusev crater, Mars
2006
[1] Water played a major role in the formation and alteration of rocks and soils in the Columbia Hills. The extent of alteration ranges from moderate to extensive. Five distinct rock compositional classes were identified; the order for degree of alteration is Watchtower ≅ Clovis > Wishstone ≅ Peace > Backstay. The rover's wheels uncovered one unusual soil (Paso Robles) that is the most S-rich material encountered. Clovis class rocks have compositions similar to Gusev plains soil but with higher Mg, Cl, and Br and lower Ca and Zn; Watchtower and Wishstone classes have high Al, Ti, and P and low Cr and Ni; Peace has high Mg and S and low Al, Na, and K; Backstay basalts have high Na and K comp…
Mineralogy of volcanic rocks in Gusev Crater, Mars: Reconciling Mössbauer, Alpha Particle X-ray Spectrometer, and Miniature Thermal Emission Spectrom…
2008
Complete sets of mineral abundances for relatively unaltered volcanic or volcaniclastic rocks in Gusev Crater have been determined by modeling Mössbauer subspectral areas as mineral weight percentages, and combining those percentages with the proportions of iron-free minerals not detected by Mössbauer (normative plagioclase, apatite, and chromite, as calculated from Alpha Particle X-Ray Spectrometer (APXS) chemical analyses). Comparisons of synthetic thermal emission spectra calculated for these mineral modes with measured Miniature Thermal Emission Spectrometer (Mini-TES) spectra for the same rock classes show either good agreements or discrepancies that we attribute to sodic pla…
Variété des usages et inégalités d'accès à la formation continue
2005
La formation professionnelle continue est rarement abordée du point de vue de la personne qui se forme. C'est cette approche originale que propose l'enquête Formation continue 2000. Son intérêt est d'observer l'attitude des individus face à la formation continue, leurs contraintes et leurs pratiques. Plus que l'envie personnelle, les propositions et les critères de sélection de l'entreprise ont une réelle influence sur l'accès à la formation des salarié-es. De plus, cette enquête permet d'éclairer les raisons et les circonstances, racontées par les personnes elles-mêmes, qui ont conduit à une absence de formation.
Adherence to international guidelines for the management of Helicobacter pylori infection among gastroenterologists and gastroenterology fellows in I…
2021
Background: Information on the management of Helicobacter (H.) pylori infection by gastroenterologists and gastroenterology fellows are scarce. We aimed to assess practice of gastroenterologists and gastroenterology fellows and their adherence to guidelines for diagnosis and treatment of H. pylori infection in Italy. Materials and Methods: All gastroenterologists and gastroenterology fellows attending the National Congress of Digestive Diseases - FISMAD were invited to fill-in an on-line questionnaire. The questionnaire included questions on the diagnosis and treatment of H. pylori infection. Results: A total of 279 gastroenterologists and 61 gastroenterology fellows participated to the stu…
Mūža mācīšanās izpratnes ietekme uz pieaugušo svešvalodu kompetences paaugstināšanu: Latvijas un Dānijas pieredze
2015
.Darbs veltīts mūža mācīšanās izpratnes un nozīmes apzināšanai Eiropā un Latvijā un Dānijā tās kontekstā. Darbā vairāk analizēta viena no Eiropas Parlamenta 2006.gadā definētajām nepieciešamajām pamatprasmēm – svešvalodu zināšanas - pieaugušo mācīšanās kontekstā. Darbā apskatīts mūža mācīšanās atbalsts Eiropas Savienības, Latvijas un Dānijas dokumentos, analizēta pieaugušo mācīšanās specifika, kā arī aplūkoti galvenie mūža mācīšanās izaicinājumi. Darba analītiskajā daļā izmantot anketēšanas metode. Iegūti dati no 59 pieaugušajiem, kuri 2014./2015.gada mijā mācījās kādu no svešvalodām Latvijā vai Dānijā. Anketu atbilžu analīzes rezultāti ir prezentēti un salīdzināti darbā. Neskatoties uz Lat…
Geochemical constraints on basalt petrogenesis in the Strait of Sicily Rift Zone (Italy): Insights into the importance of short lengthscale mantle he…
2020
Igneous activity from the late Miocene to historic time (most recently 1891 CE) in the Strait of Sicily has created two volcanic islands (Pantelleria and Linosa) and several seamounts. These volcanoes are dominated by transitional (ol + hy-normative) to alkaline (ne-normative) basaltic lavas and scoriae; volcanic felsic rocks (peralkaline trachyte-rhyolite) crop out only on Pantelleria. Although most likely erupted through continental crust, basalts demonstrate no evidence of crustal contamination and are geochemically similar to oceanic island basalts (OIB). Despite their isotopic similarities, there are considerable compositional differences with respect to major and trace element geochem…
