Evaluating the Efficiency of Different Regression, Decision Tree, and Bayesian Machine Learning Algorithms in Spatial Piping Erosion Susceptibility U…
2020
Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on random forest (RF), support vector machine (SVM), and Bayesian generalized linear models (Bayesian GLM) machine learning algorithms. For this goal, due to the importance of various geo-environmental and soil properties in the evolution and creation of piping erosion, 18 variables were considered for modeling the piping erosion susceptibility in the Zarandieh watershed. A total of 152 points of piping erosion were recognized in the study area that…
Varying plant protein sources in the diet of sea bass Dicentrarchus labrax differently affects lipid metabolism and deposition
2010
The liver activity of lipogenic enzymes, the lipid content in various tissues, and plasma lipid levels of major, were measured in sea bass (D. labrax) fed over 96 days either a, fish meal-based control diet or preparations where 70% of fish meal protein was replaced by wheat gluten singly or in combination with pea or soybean meals. Relative to the controls, sea bass fed the wheat gluten-based diet resulted in stimulated lipogenesis in liver and increased lipid deposition in muscle. The opposite occurred when a substantial amount of soybean meal was included in the diet. Mesenteric fat depots were apparently insensitive to major changes in dietary protein source in fish showing similar inta…
El Paleolítico Medio y Superior en la desembocadura del río Millars (Castelló). Geocronología de las terrazas pleistocenas y estudio morfotécnico de …
2011
Los recientes trabajos geoarqueológicos llevados a cabo en el tramo final del rio Millars (Castelló), concretamente en la zona próxima a su desembocadura, han proporcionado datos geomorfológicos y geocronológicos de interés. Las dataciones numéricas por OSL indican el desarrollo de las terrazas bajas del río (T5 y T6) en el MIS 2, entre 25.000 y 21.000 años B.P. aproximadamente. Estos datos permiten contextualizar los conjuntos del Paleolítico Medio y Superior existentes, cuyo análisis morfotécnico se incluye en el presente estudio.

Reconstrucción paleoambiental del Pleistoceno Superior en la desembocadura del río Millars a través del análisis palinológico
2011
Se presentan los resultados del análisis palinológico efectuado sobre sedimentos del Pleistoceno superior en la desembocadura del río Millars, que han permitido detectar un episodio frío que interrumpió la vegetación presente en la zona y ejerció un efecto de debilitamiento sobre el caudal del río. La presencia de polen de arbustos termófilos constata la importancia del litoral castellonense como zona refugio durante el último máximo glacial. La interpretación paleoclimática está basada en la variación de los porcentajes de Pinus, Juniperus, arbustos mesotermófilos y elementos acuáticos.
Militari italiani e grande guerra
2015
Il saggio verte su alcuni aspetti dei fenomeni immigratori che si collegano alla genesi e alla tenuta dei sensi di appartenenza etnica e nazionale. Accanto alla progressiva rimozione dei vecchi meccanismi di acculturazione linguistica, che scalzano, ove posseduto in partenza, l’italiano procurando la sua sostituzione progressiva –e in parte fisiologica– con il castigliano si assiste in America, per integrazione, anche al declino dell’“italianità politica”. Un momento di svolta prima del definitivo affermarsi di tale processo di “argentinizzazione” fu rappresentato però dalla congiuntura della grande guerra. Il suo deflagrare, infatti, coincise con il momento di massima espansione (non solo …
Italia en la periferia del Mediterráneo. Las relaciones ítalo-españolas entre los siglos XIX y XX: política, economía y sociedad
2015
The birth of Italian Kingdom helped to change in a very remarkable way the political and economic relations established in Europe along the 19th century. Countries like Great Britain, France or Germany had to consider the presence of this modest southern state, above all keeping in mind their future enlargement along the Mediterranean area. In this context, also Spain -lost in a deep and centuries-old political decadence- could not avoid paying attention to this close and historical linguistic relative. Even though the relation between both countries was not easy in the very beginning, later it gave place to a constant exchange of agreements, treaties and even cultural cooperation. The appr…
Closed tank pneumatic press application to improve Sauvignon Blanc wine quality and nutraceutical properties
2019
The machines used in the winemaking process directly affect the quality of wine and its nutraceutical properties. Grapes-pressing is a very important step in winemaking as it may promote the presence and/or absence of enzymatic processes on the must, leading to the creation of different products in terms of chemical composition, starting from the same grapes. The aim of the study was to compare two different pressing systems of Sauvignon Blanc grapes using an innovative pneumatic discontinuous closed tank press in two operating modes: the traditional pressing mode in presence of oxygen and the inert pressing mode, performed through grapes pressing under inert gas with nitrogen recovery. Che…
Väärinymmärretty kuningas : asteekkihallitsija Montezuma Meksikon valloittaneiden espanjalaisten konkestadorien selonteoissa
2011
Artikkelissa tarkastellaan Meksikon espanjalaisvalloittajien asteekkihallitsija Montezumasta laatimia kuvauksia. Kirjallisuudessa Montezuma on nähty arkana ja alistuvana johtajana, jonka heikkouksia on pidetty syynä asteekkien tappioon vieraita valloittajia vastaan. Käsitys juontuu asteekkeilta valloituksen jälkeen kootusta perimätiedosta, jolle espanjalaisten valloittajien laatimien muistelmien ja raporttien tiedot on nähty vahvistuksena. Artikkelissa selitetään Montezuman kuvauksia sijoittamalla Montezuman omin silmin nähneiden valloittajien kirjoittamat lähteet konteksteihinsa tutkimuksen ja aikalaiskirjallisuuden avulla. Artikkelissa osoitetaan, että mikäli lähteiden kohdalla otetaan hu…
