Cronoestratigrafía de la terraza compleja del río Guadalquivir en "Las Jarillas" T-12 (+26-32 m): industria lítica y macro fauna asociada (La Rinconada, Sevilla)

The Jarillas terrace, the last level of the Guadalquivir river´s Complex of the middle terraces (T12, +26-32 m), displays a stratigraphy of 6 units (USLC1, 2, 3, 4, 5 and 6) inserted in at least 4 alluvial cycles. Lithic Acheulean industry has been obtained from the same associated to the wall unit (CAB- 1) together with remains of macromammal fauna and with further evolved elements in those subsequent (CAB-2&3).The results obtained by dating method TL and through Palaeolithic correlation, indicate the development of the terrace during the second half of the Middle Palaeolithic

The complex terrace "Las Jarillas" of the Guadalquivir river (La Rinconada, Sevilla. SW of Spain): chronostratigraphy, lithic industry and associated macromammal fauna

La terraza de Jarillas, último nivel del Complejo de terrazas Medias del Guadalquivir en su tramo bajo (T12, a +26-32 m), ha sido tradicionalmente adscrita al tránsito Pleistoceno Medio-Superior en base a los restos paleontológicos de “Elephas” (Palaeoloxodon) Antiquus y a la industria lítica de Paleolítico Inferior y Medio en ella localizada. En este trabajo se presenta su modelo de estratigrafía, a partir del estudio de los perfiles de la explotación de áridos “Sando-La Cabaña” (SLC), con 6 unidades (USLC1, 2, 3, 4, 5 y 6) insertas en al menos 4 ciclos de aluvionamientos yuxtapuestos, situando la nueva y abundante industria lítica Achelense encontrada (747 piezas) tanto en la unidad inferior (USLC1, CAB1) como en las intermedias (USLC2 y USLC3, CAB2 y CAB3) junto con los numerosos restos de macro-fauna asociados. Se propone la equivalencia de este modelo con las anteriores unidades establecidas en las desaparecidas graveras de “Pionner” y “Antiguas Jarillas”, estableciendo por primera vez un marco cronológico de referencia para todo el aluvionamiento a partir de dataciones por termoluminiscencia (TL) y la comparación de los restos de macrofauna encontrados con la Escala Bioestratigráfica de la Cordillera Bética. De ello se desprende que los tres primeros ciclos del aluvionamiento (unidades USLC1, 2, 3 y 4) se habrían constituido a partir del Pleno Pleistoceno Medio, entre los 400-450 ka y los >150 ka, con industria de Achelense pleno mientras que el último (unidades USLC5 y 6), superpuesto lateralmente a los anteriores, comenzaría su deposición durante el final del Pleistoceno Medio e inicios del Pleistoceno Superior (130 a 80 ka) y sería el que contiene las industrias de Paleolítico Medio detectadas hasta la fecha en esta terraza.The Jarillas terrace, the last level of the Guadalquivir`s terraces Middle complex in the lower course of the river, has been traditionally assigned to the transit Middle-Upper Pleistocene based on the paleontological remains of Elephas (Palaeloxodon) Antiquus and the Lower and Middle Paleolithic ́s industries located in it. In this paper we present its model of stratigraphy, based on the profiles of the “Sando-La Cabaña” (SLC) quarry with six units (USLC1, 2, 3, 4, 5 and 6) inserted in at least four juxtaposed cycles of fluvial deposits, localizing the new and abundant Acheulean lithic industry found (747 pieces) in the lower unit (USLC1, CAB1) as well as in the intermediate ones (USLC2 and ULC3, CAB2 and CAB3) together with the numerous remains of the associated macro-fauna. We propose the equivalency of this model with the known units of the extinct gravel-mining of “Pionner” and “Antiguas Jarillas” establishing for the first time a chronological framework of reference for all of the fluvial deposit originated from thermoluminescence dating (TL) and the comparison of the macrofauna remains found with the “Bioestratigrafic Scale of the Cordillera Bética”. From this emerges that the first three cycles of the fluvial deposit (units USLC1, 2, 3 and 4) would have been constituted from the full Middle Pleistocene, between 400-450 ka and more than 150 ka, with full Acheulean industry while the last cycle (units USLC5 and 6), laterally one on top of the other, would have commenced its deposition during the end of the Middle Pleistocene and the beginning of the Upper Pleistocene (130 to 80 ka) and it would be that which contains the Middle Pleistocene industries detected to date in this terrace

Modelling growth and decline in a two-species model system: Pathogenic Escherichia coli O157:H7 and psychrotrophic spoilage bacteria in milk

Producción CientíficaShiga toxin-producing Escherichia coli O157:H7 is a food-borne pathogen and the major cause of hemorrhagic colitis. Pseudomonas is the genus most frequent psychrotrophic spoilage microorganisms present in milk. Two-species bacterial systems with E. coli O157:H7, non-pathogenic E. coli, and P. fluorescens in skimmed milk at 7, 13, 19, or 25 °C were studied. Bacterial interactions were modelled after applying a Bayesian approach. No direct correlation between P. fluorescens’s growth rate and its effect on the maximum population densities of E. coli species was found. The results show the complexity of the interactions between two species in a food model. The use of natural microbiota members to control foodborne pathogens could be useful to improve food safety during the processing and storage of refrigerated foods

Restos de macromamíferos en la terraza t12 del Guadalquivir en la Rinconada (Sevilla): presencia de Hippopotamus amphibius Linneo, 1758.

The T12 terrace of the Guadalquivir River has been found to be the point of reference in the paleontological macrommal fauna of the second half of the Middle Pleistocene together with the associated acheulean industry. The presence of a hippopotamus of great dimensions found in the base of the terrace opens a new interpretation of the chronology and the climatic environment at the beginning of the formation of the terrace during the MIS 12

The concept of death in children aged from 9 to 11 years: Evidences through inductive and deductive analysis of drawings

The objective of the research was to analyze children’s conceptualization of death through drawings, using a mixed approach, which combines deductive and inductive qualitative analysis. The sample consisted of 99 children aged 9–11 years, who were asked to elaborate a drawing about their idea of death and to explain it to the researchers. Drawings were coded basing on Tamm and Granqvist’s model (deductive analysis) and codes and categories were created and modified (inductive analysis). Three main categories were identified in the analysis and four sub-categories were modified and/or created: causes of death, good death, anxiety-fear and symbolization

El pleistoceno medio y superior en la secuencia ceneral de las terrazas del Guadalquivir (sgtg): nuevas dataciones por luminiscencia de la t12 y t13 en la Rinconada (SW de España)

This work includes the luminescence dating (quartz-OSL, pIRIR on K-feldespar and TL) of the T12 and T13 terraces of the Guadalquivir River near La Rinconada (Seville). Lithic Achelense industry is located from the basal USLC-1 unit of T12, together with remains of macromammal fauna. The results obtained of the analysis of the T12 terrace in “Sando-La Cabaña” show that the age or the unit lower in the terrace is older than 240 ka, probably, corresponding to MIS12-MIS11 or MIS10-MIS9.The upper part of the alluvial formation of the T13 presents an absolute age (quartz-OSL) of ca.75 ka (MIS5a)

Análisis arqueosismológico del conjunto arqueológico romano de Mulva- Munigua (Sevilla, España). Resultados preliminares

El conjunto arqueológico romano de Mulva-Munigua (Sevilla, España) presenta daños en las edificaciones que pueden ser interpretadas como resultado de la ocurrencia de un evento sísmico (Efectos Arqueológicos de los Terremotos: EAEs) a finales del siglo III A.D., fecha coincidente con el inicio del periodo de declive económico de este asentamiento romano. Para intentar establecer el posible origen sísmico de las deformaciones, se ha procedido al inventario y análisis de las estructuras deformadas presentes en el yacimiento. No obstante, algunas de estas deformaciones también se pueden interpretar como resultado de procesos gravitaciones asociados a la ladera Este de la colina sobre la que se sitúa parte del yacimiento. Las direcciones de máxima deformación (ey) obtenidas del análisis de EAEs indica dos direcciones preferentes de la deformación (o movimiento preferente del terreno): NNO-SSE y ENEOSO. Aunque los datos presentan una dispersión importante, se puede establecer que la orientación principal NNO-SSE es compatible con un evento sísmico situado en el borde norte del Valle del Guadalquivir. La orientación ENE-OSO podría relacionarse con un evento posterior, o más seguramente con procesos de ladera de carácter cosísmico o no.The Roman archaeological site of Mulva-Munigua (Sevilla, Spain) displays building damage features suggesting a seismic origin (Earthquake Archaeological Effects: EAEs). The proposed seismic event could be tentatively dated in the late 3rd century AD, coinciding with the beginning of the economic fall of the Roman Empire at Iberia. However, some of the recorded EAEs can be also interpreted as a result of intervening slope movements in the eastern hillslope of this roman site. The inventory and analysis of the proposed EAEs make possible to discern between seismic oriented damage and other causes. In spite of the data show a significant dispersion, their analysis result in two different orientations of maximum deformation (ey) or preferential ground movement: NNW-SSE and ENE-WSW. The main ey orientation (NNW-SSE) can be tentatively related to a seismic event occurred in the environs of the northern border of the Guadalquivir Depression. The secondary orientation (ENE-WSW) can be interpreted as a consequence of latter slope movements triggered (or not) by other ancient earthquakes

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
