Physics - General Physics - Abstract
Based on simplified one-dimensional steady-state analysis of thermoelectric phenomena and on analogies between thermal and electrical domains, we propose both lumped and distributed parameter electrical models for thermoelectric devices. For lumped parameter models, constant values for material properties are extracted from polynomial fit curves evaluated at different module temperatures (hot side, cold side, average, and mean module temperature). For the case of distributed parameter models, material properties are calculated according to the mean temperature at each segment of a sectioned device. A couple of important advantages of the presented models are that temperature dependence of material properties is considered and that they can be easily simulated using an electronic simulation tool such as SPICE. Comparisons are made between SPICE simulations for a single-pellet module using the proposed models and with numerical simulations carried out with Mathematica software. Results illustrate accuracy of the distributed parameter models and show how inappropriate is to assume, in some cases, constant material parameters for an entire thermoelectric element., Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions)

Condensed Matter ,Nonlinear Sciences - Chaotic Dynamics - Abstract
Self-sustained time-dependent current oscillations under dc voltage bias have been observed in recent experiments on n-doped semiconductor superlattices with sequential resonant tunneling. The current oscillations are caused by the motion and recycling of the domain wall separating low- and high-electric- field regions of the superlattice, as the analysis of a discrete drift model shows and experimental evidence supports. Numerical simulation shows that different nonlinear dynamical regimes of the domain wall appear when an external microwave signal is superimposed on the dc bias and its driving frequency and driving amplitude vary. On the frequency - amplitude parameter plane, there are regions of entrainment and quasiperiodicity forming Arnol'd tongues. Chaos is demonstrated to appear at the boundaries of the tongues and in the regions where they overlap. Coexistence of up to four electric-field domains randomly nucleated in space is detected under ac+dc driving., Comment: 9 pages, LaTex, RevTex. 12 uuencoded figures (1.8M) should be requested by e-mail from the author

- Abstract
Dientamoeba fragilis is a protozoan that parasitizes the large intestine of humans and domestic animals. To date, some aspects regarding D. fragilis life cycle, including hosts, reservoirs, infection mechanism, among others, are not yet clear. Swine are considered natural hosts for this protozoan, therefore their close contact with humans promotes its zoonotic transmission. In Colombia there are no studies on the presence of D. fragilis in animal hosts, including pigs, and data about other intestinal protozoa are scarce. The objective was to determine the prevalence of intestinal protozoan, including D. fragilis, in pigs raised in a farm from a rural area of Medellin (Andean region of Colombia). Fecal samples from 70 pigs in prefattening stage were collected. Direct fecal smear examination, trichrome and modified Ziehl-Neelsen stain were used in the study. Univariate analysis (frequency distribution and central tendency measures) and bivariate analysis were used to explore risk factors. Dientamoeba fragilis was found in 13% of the evaluated fecal samples. Other parasites detected included: Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%), and Giardia spp. (1,4%). This is the first report of D. fragilis in swine in Colombia, and the high prevalence of other pathogen protozoa was also observed, which corroborates the role of pigs as important reservoirs for human infections. Studies focused on the evaluation of both swine and swine-exposed farm workers should be done in order to know the dynamics of transmission of this parasite., Dientamoeba fragilis es un protozoario que parasita el intestino grueso del hombre y animales domésticos. Hasta el momento, aún no son claros aspectos de su ciclo de vida, como el rango de hospedadores, reservorios, mecanismo de infección, entre otros. Se postula que el cerdo es un hospedador natural para este protozoario y que, debido a su cercanía con el humano, podría facilitar una transmisión zoonótica. En Colombia no existen a la fecha estudios sobre la presencia de D. fragilis en hospedadores animales, incluidos los cerdos, y los datos sobre la prevalencia de otros protozoarios intestinales en estos animales son escasos. El objetivo fue determinar la frecuencia de protozoarios intestinales, incluyendo D. fragilis, en cerdos de una granja tecnificada de una zona rural de Medellín (región Andina de Colombia). Se recolectaron muestras de materia fecal de 70 cerdos en etapa de preceba, que fueron evaluadas mediante examen directo, tinción tricrómica y Ziehl-Neelsen modificado. Se realizaron análisis univariados con medidas de frecuencia relativa y tendencia central y análisis bivariados para la exploración de factores de riesgo. Se detectó la presencia de D. fragilis en un 13% de las muestras y de otros parásitos como Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%) y Giardia spp. (1,4%). En este primer reporte de D. fragilis en cerdos en Colombia se observó la alta prevalencia de otros protozoarios patógenos, lo que corrobora el papel de los cerdos como importantes reservorios de infecciones humanas.

- Abstract
Global warming and fossil fuel depletion have boosted the search for alternative and renewable fuels with a low environmental impact. Biodiesel exhibits many advantages over conventional diesel including the possibility of being produced from renewable sources such as waste oils and fats. Specifically, waste animal fats are receiving increased attention as an alternative to vegetable oils for biodiesel production. This low-cost feedstock allows the mitigation of environmental pollution and can also improve biodiesel features by increasing cetane number and enhancing oxidative stability. Among the different technologies available for biodiesel production, supercritical processes offer important advantages over conventional catalytic transesterification in terms of process efficiency and reaction time. According to the increasing interest and number of research articles published in this field in the last years, this work focuses on the systematic review of the technology by using the Systematic Reviews and Meta-Analysis (PRISMA) methodology. This work describes the state of the art of non-catalytic supercritical production of biodiesel using animal fats as a feedstock and discusses the key aspects of the process such as the type of fat used, operation variables including reaction time, temperature, solvent excess, pressure, and solvent excess, and the final properties of the synthesized biodiesel.

Objetive: To evaluate, over a 79.2-month follow-up period, the behavior of bone mineral density (BMD) determined by Computerized Axial Densitometry (DXA), volumetric bone mineral density (BMDvol) and its relationship with anthropometric data, together with the parameters related to bone metabolism (calcium, phosphorus, alkaline phosphatase, parathormone (PTH) and vitamin D (25-OH-D3)) in a child population with Type 1 Diabetes Mellitus (DM1) without microvascular complications and a control group of reference with similar characteristics. Material and methods: Initially, a cross-sectional study was carried out in 40 diabetic children (mean age 9.4±2.8 years) and 108 controls (9.3±1.5 years) to assess the possible differences between the two populations. 26 patients from the initial diabetic group were reassessed after 79.2 months of follow-up. Results: It was observed that, at baseline, bone mass was similar in diabetics and controls. After follow-up, the BMD of the diabetic children was much lower than that expected in the non-diabetic child population. Weight, height, and Body Mass Index (BMI) followed the same pattern as BMD. The values of calcium, phosphorus, alkaline phosphatase, PTH and vitamin D, although within the normal range, were lower than in the controls. Alkaline phosphatase did not increase in the pubertal period. Conclusions: The present study demonstrates that children and adolescents with a recent diagnosis of DM1 have a normal BMD. However, over time, and especially during adolescence, they show less bone mass gain and changes in bone turnover parameters. [ABSTRACT FROM AUTHOR]

Background: The impact of biologics on the risk of postoperative complications (PC) in inflammatory bowel disease (IBD) is still an ongoing debate. This lack of evidence is more relevant for ustekinumab and vedolizumab. Aims: To evaluate the impact of biologics on the risk of PC. Methods: A retrospective study was performed in 37 centres. Patients treated with biologics within 12 weeks before surgery were considered “exposed”. The impact of the exposure on the risk of 30-day PC and the risk of infections was assessed by logistic regression and propensity score-matched analysis. Results: A total of 1535 surgeries were performed on 1370 patients. Of them, 711 surgeries were conducted in the exposed cohort (584 anti-TNF, 58 vedolizumab and 69 ustekinumab). In the multivariate analysis, male gender (OR: 1.5, 95% CI: 1.2–2.0), urgent surgery (OR: 1.6, 95% CI: 1.2–2.2), laparotomy approach (OR: 1.5, 95% CI: 1.1–1.9) and severe anaemia (OR: 1.8, 95% CI: 1.3–2.6) had higher risk of PC, while academic hospitals had significantly lower risk. Exposure to biologics (either anti-TNF, vedolizumab or ustekinumab) did not increase the risk of PC (OR: 1.2, 95% CI: 0.97–1.58), although it could be a risk factor for postoperative infections (OR 1.5, 95% CI: 1.03–2.27). Conclusions: Preoperative administration of biologics does not seem to be a risk factor for overall PC, although it may be so for postoperative infections.

- Abstract
Ceramic materials based on naturally occurring clays are a low cost and environmentally friendly alternative to commercial polymer-based membranes in bioelectrochemical systems. In this work, ceramic membranes containing different amounts of iron oxide (1.06, 2.76 and 5.75 vol.%) and sintered at different temperatures (1100, 1200 and 1300 °C) have been elaborated and tested as separators in urine-fed microbial fuel cells (MFCs). The results reveal that the presence of iron oxide in the ceramic membrane composition increases the structural porosity and reduces the pore size for the three temperatures investigated. On the other hand, it was also observed that the iron content mitigates the negative effect of the high sintering temperature on the power performance of the MFCs. In the case of the ceramic membranes sintered at 1300 °C, power output improved ca. 10-fold when the iron oxide content in the membrane increased from 1.06 up to 5.75 vol.% (30.9 and 286.6 µW, respectively). Amongst the different combinations of iron phase content and sintering temperatures, the maximum power output was obtained by MFCs working with separators containing 5.75 vol. % of iron oxide and sintered at 1100 °C (1.045 mW). Finally, the system was stable for 65 days, which supports the long-term functionality of the different materials assessed.

- Abstract
A new record from a long sediment core (S3) in Navamuño (1505 m asl, western Iberian Central System) provides the reconstruction of the vegetation history and environmental changes in the region between 15.6 and 10.6 ka cal BP, namely during the Late Glacial and the early Holocene, using a multiproxy analysis (pollen-based vegetation and climate reconstruction, sedimentary macrocharcoals, loss-on-ignition, magnetic susceptibility and X-ray fluorescence (XRF) measurements). The results are then compared with other sequences from the Iberian Central System and the whole Iberian Peninsula in order to better understand the past dynamics of the main forest constituents. The pollen record shows a shift from open pine forests ∼15.6–14.7 ka cal BP (Oldest Dryas) to mixed open pine-birch woodlands ∼14.7–14.0 ka cal BP (Bølling). Woodlands were succeeded by a steppe-like landscape until ∼13.4 ka cal BP (Older Dryas), which was replaced again by high-mountain pine forests and riparian woodlands ∼13.4–12.6 ka cal BP (Allerød). A great development of cold steppe grasslands linked to the decline of birch woodlands is documented ∼12.6–11.7 ka cal BP (Younger Dryas). The early Holocene (11.7–10.6 ka cal BP) was characterized by a progressive reforestation of the study area by pine and birch forests in the highlands and oak woods in the lowlands. Temperate tree taxa (Carpinus betulus, Castanea sativa, Corylus avellana, Fraxinus, Juglans, Tilia, and Ulmus) were also common but likely at lower elevations. Pollen of Fagus sylvatica was already recorded during the Late Glacial and the early Holocene. The marked increasing local fire activity during the warmer and wetter Allerød oscillation could be related to a rise in tree cover, supporting the climatically driven character of these fires. Nevertheless, the strong increase in fire activity during the Younger Dryas would probably be related to growing tree and shrub mortality, as well as to the wet/dry biphasic structure of this stadial

- Abstract
This study presents the results of the archaeological investigation in Benzú Cave, located on the North African shore of the Strait of Gibraltar. The archaeological deposits, approximately 1 m deep, belong to two occupational levels dated to the Neolithic and the Bronze Age. A wide range of artifacts was found, and this led to an interdisciplinary study that led us to reach new conclusions concerning the material life, subsistence economy, and environment of the Neolithic and Bronze Age societies in northern Africa and the southern Iberian Peninsula.

- Abstract
Rainha Cláudia verde' (Prunnus domestica L. ssp Domestica) é uma variedade de ameixa conhecida como um produto regional típico do Alentejo, com interesse económico e social importante para a região e protegido com a Denominação de Origem Ameixa de Elvas reconhecida pelo decreto nº 49/94 20/01. Com este estudo pretendeu-se identificar quais os atributos sensoriais, que mais influenciam a Avaliação global das ameixas desta variedade e analisar a relação entre dados instrumentais e sensoriais. Para caracterizar a qualidade sob o ponto de vista instrumental foram analisados parâmetros físicos (perda de peso e cor da epiderme), reológicos (Firmeza da pele e da polpa) e químicos (concentração de sólidos solúveis totais e acidez). A qualidade sensorial foi estudada recorrendo-se a análise sensorial descritiva, para atributos visuais (Aspecto exterior, Cor da pele e Cor da polpa), de sabor e odor (Doce, Ácido e Sabores/aromas característicos da ameixa), texturais (Firmeza e Suculência) e a Avaliação global. Os atributos que mais contribuíram para a Avaliação global da qualidade destes frutos foram por ordem decrescente de importância: a Suculência, o Doce, os Sabores/aromas característicos da ameixa, a acidez e a Firmeza. No estudo das correlações entre parâmetros instrumentais e sensoriais foram encontrados correlações significativas entre o atributo Suculência e o parâmetro instrumental Firmeza da polpa (r = 0,72) e entre o atributo Firmeza e o parâmetro instrumental Firmeza da pele (r = 0,71). A medição da Firmeza de forma instrumental parece reflectir com bastante fiabilidade a avaliação da Textura e Suculência dos frutos por parte do painel de provadores, o que pode ter grande interesse para a avaliação da qualidade de forma expedita., Revista de Ciências Agrárias, vol. 30 n.º 1 (2007)

- Abstract
'Rainha Cláudia verde' (Prunnus domesticaL. ssp Domestica) is a regional commodity from Alentejo known with a Protected Origin Denomination of Ameixa de Elvas decree nº 49/94 20/01. The aim of this work is to identify the most important attributes determinant for the global evaluation of these fruits and to study the relation among instrumental and sensorial evaluation. In order to carried out an instrumental assessment the following quality parameters were evaluated: weight loss, external colour (L* a* b*), visual assessment of the epidermis, epidermis puncture test, mesocarp penetration test, soluble solids content (SSC), titratable acidity and pH. Sensorial evaluation considered visual attributes (Outer aspect, Skin colour, Pulp colour), flavour (Sweetness, Acidity, Typical flavour), texture (Firmness and Juiciness) and Global evaluation. The most important attributes for final classification were by decreased order: Juiciness, Sweetness, Typical flavour, Acidity and Firmness. Correlation between instrumental and sensorial parameters were significant for Juiciness and Pulp firmness (r = 0,72) and Sensorial firmness and Skin firmness (r = 0,71). Instrumental firmness reflects textural and juiciness sensorial characteristics of these fruits, fact that could be very useful to preview the quality of plums Rainha Cláudia verde., Rainha Cláudia verde' (Prunnus domesticaL. ssp Domestica) é uma variedade de ameixa conhecida como um produto regional típico do Alentejo, com interesse económico e social importante para a região e protegido com a Denominação de Origem Ameixa de Elvas reconhecida pelo decreto nº 49/94 20/01.

University teachers should devote time to three tasks: teaching, research and management. Some teachers do not knowhow to manage their time well so teaching tasks take too much time. In order to conductresearch or fulfil their managementresponsibilities, they are obliged to work more hours than those stipulated in their contracts. Furthermore, they often havethe feeling that, despite the long hours devoted to teaching, their students fail to obtain the results desired, and this feelingleads to frustration. Some ideas for helping teachers to optimize their teaching time are presented in this article, so that byimproving their quality of teaching the number of hours can be reduced and, at the same time, better results can be achievedby their students.

[EN] The archaeological site of La Esparragosa is located in the province of Cadiz, Spain, on the northern shore of the Strait of Gibraltar. The tomb under consideration is an exceptional example, within the context of the so-called “Silos Fields culture”. Excavations have attested a burial pit for one individual, who was found covered by a layer of Ruditapes decussatus (clam) (477 specimens in total). This article presents the first results of the multidisciplinary studies carried out on this burial, including 14C AMS and TL datings, physical anthropology studies and archaeozoological, archaeometrical, use-wear and pollen analysis. These studies highlight the importance of marine resources for this community, both in economic and ideological terms., [ES] El yacimiento de La Esparragosa se encuentra ubicado en la provincia de Cádiz (España), en plena orilla norte del Estrecho de Gibraltar. La tumba que nos ocupa constituye un caso excepcional para la denominada «cultura de los silos», ya que se ha podido documentar en este enterramiento en fosa la existencia de un individuo cubierto por una capa de 477 ejemplares de Ruditapes decussatus (almeja fina). Presentamos un avance del estudio interdisciplinar con dataciones de 14C AMS (una de las cuales es inédita) y TL, antropología física, arqueozoología, funcionalidad y análisis polínico. Estos estudios ponen de relieve la importancia que desempeñó el medio marino para esta comunidad tanto a nivel económico como a nivel ideológico., Este estudio se incluye dentro del Proyecto de Investigación de I+D HAR2017-87324-P, «Análisis de sociedades prehistóricas (del Paleolítico Medio al Neolítico Final) en las dos orillas del Estrecho de Gibraltar.

[EN] The accelerated urban expansion produced in large metropolitan areas such as Valencia Metropolitan Area in recent decades has important environmental impacts including “soil sealing” and the loss of valuable natural areas. The aim of this paper is to analyze the evolution of artificial soil in the Metropolitan Area of Valencia (AMV) between 1984-2011 using Landsat TM and ETM+ images, that have been validated from SIOSE data with larger spatial resolution. Results point out, with an accuracy of 71%, that artificial surface raised in 8000 ha which represents an increase of 10% for sealing soil and 34% of the whole land covers of the AMV., [ES] La expansión urbana acelerada producida en décadas recientes en las grandes áreas metropolitanas como Valencia conlleva importantes impactos ambientales, entre ellos la impermeabilización o “sellado antropogénico” del suelo y la pérdida de espacios naturales de gran valor paisajístico.

- Abstract
Traditionally, Spanish schools of civil engineering provide their students a class on “Technical English” in order to develop their language skills. However, this class does not cover all the skills that the student would need in the labor market and mainly focuses in the reading and writing skills, and in a lower degree in the speaking and listening ones. This paper proposes a series of innovative and informal training activities, such as cine-forum on technical civil engineering topics and role playing on real professional situations, that allow Spanish civil engineering students to develop English skills, that can rarely be worked in the classroom (i. e. speaking, negotiating and conversing), which encourage debate, participation, and foster their self-confidence to speak about technical-English topics in public. Although the students’ level of English is much lower than expected, they all agree on the importance of technical English for their future career. The results also show the students’ lack in skills that are difficult to train in regular classes (speaking and talking). Consequently, this situation would require to provide complementary activities like the ones suggested in this project in order to develop these skills and increase the students’ demand for engineering classes taught in English., В последние годы традиционное преподавание с использованием обычной доски дополняется визуальными средствами, такими как слайд-проекторы и видео. Феноменальный рост Интернета привел к появлению новых учебных средств массовой информации, таких как онлайн-курсы общего пользования, которые делают доступными образовательные ресурсы для более широкого и удаленного контингента студентов. Легкий доступ к образованию может повысить мотивацию, что является полезным коммерческим инструментом для университетов. В отличие от других дисциплин, таких как экономика или психология, МООК редко используются для распространения курсов по дисциплинам направления «Строительство». Чтобы восполнить этот пробел и поощрить использование МООК среди строительных университетов, в настоящем документе представлен опыт создания такого курса для многодисциплинарного проектирования мостов, созданных Университетом Кастилии и Ла Манча. Этот курс основан на опыте, полученном на конкурсе по строительству мостов с заданиями для студентов‑магистрантов, организованных Университетом Кастилии и Ла Манча в 2015, 2016 и 2017 годах.

- Abstract
Ethylene, nitric oxide (NO) and glutathione (GSH) increase in Fe-deficient roots of Strategy I species where they participate in the up-regulation of Fe acquisition genes. However, S-nitrosoglutathione (GSNO), derived from NO and GSH, decreases in Fe-deficient roots. GSNO content is regulated by the GSNO-degrading enzyme S-nitrosoglutathione reductase (GSNOR). On the other hand, there are several results showing that the regulation of Fe acquisition genes does not solely depend on hormones and signaling molecules (such as ethylene or NO), which would act as activators, but also on the internal Fe content of plants, which would act as a repressor. Moreover, different results suggest that total Fe in roots is not the repressor of Fe acquisition genes, but rather the repressor is a Fe signal that moves from shoots to roots through the phloem [hereafter named LOng Distance Iron Signal (LODIS)]. To look further in the possible interactions between LODIS, ethylene and GSNOR, we compared Arabidopsis WT Columbia and LODIS-deficient mutant opt3-2 plants subjected to different Fe treatments that alter LODIS content. The opt3-2 mutant is impaired in the loading of shoot Fe into the phloem and presents constitutive expression of Fe acquisition genes. In roots of both Columbia and opt3-2 plants we determined 1-aminocyclopropane-1-carboxylic acid (ACC, ethylene precursor), expression of ethylene synthesis and signaling genes, and GSNOR expression and activity. The results obtained showed that both ‘ethylene’ (ACC and the expression of ethylene synthesis and signaling genes) and ‘GSNOR’ (expression and activity) increased in Fe-deficient WT Columbia roots. Additionally, Fe-sufficient opt3-2 roots had higher ‘ethylene’ and ‘GSNOR’ than Fe-sufficient WT Columbia roots. The increase of both ‘ethylene’ and ‘GSNOR’ was not related to the total root Fe content but to the absence of a Fe shoot signal (LODIS), and was associated with the up-regulation of Fe acquisition genes.

La prevalencia de la polinosis está aumentando en los países desarrollados en las últimas décadas, siendo una enfermedad que ocasiona un gran número de días de pérdida de actividad laboral o de asistencia a la escuela, por lo que, además de los costes directos ligados a la enfermedad, ocasiona importantes costes indirectos. La evitación de la exposición es la medida preventiva más eficaz. El disponer de datos aerobiológicos para áreas geográficas homogéneas permite a los enfermos, tanto poner en marcha medidas preventivas, como optimizar el periodo de uso de medicamentos y mejorar la calidad de vida. Las redes aerobiológicas deben decidir el modo en que suministra la información. En el caso de información destinada a la población general, es más útil difundirla como intervalos de concentraciones ajustados a categorías de valores umbrales bajos, medios, altos o muy altos, que a un dato numérico concreto que puede no alcanzar el objetivo perseguido.En este trabajo hemos analizado esta información para los datos generados en la Red Aerobiológica de la Región de Murcia y a partir de las bases de datos aerobiológicas del periodo 2010-2016 hemos propuesto, basado en el análisis de los percentiles 90, 95, 97 y 99 de la serie temporal, unos valores umbrales, en cuatro escalones, bajo, medio, alto y muy alto para los tipos polínicos Poaceae y Urticaceae en la ciudades de Cartagena, Murcia y Lorca, que mejoran la información suministrada por la Red Aerobiológica de la Región de Murcia encaminada a que los pacientes alérgicos emprendan las medidas de evitación y el tratamiento farmacológico. The incidence of pollinosis in developed countries has been on the rise for the past few decades. It is an illness that leads to a large number of missed work and school days. Therefore, in addition to the direct costs associated therewith, it also causes significant indirect costs. Avoidance to exposure is the most effective preventive measure. With aerobiological data for homogeneous geographical areas, sick people can both take preventive measures and optimize the period of usage of drugs and thus improve the quality of their life. Aerobiological networks have to decide how to provide this information. In the case of information intended for the general public, it is more useful to give it as concentration ranges adjusted to categories of low, medium and high/very high threshold values than as specific numerical values, which might not achieve the desired goal.In this paper we have analyzed the data generated by the Aerobiological Network of the Region of Murcia, Spain, from aerobiological databases in the 2010-2016 period. Based on the analysis of the 90, 95, 97 and 99 percentiles of the time series, we have proposed threshold values —in four levels (low, medium, high and very high), for the Poaceae and Urticaceae pollen types in the towns of Cartagena, Lorca and Murcia— that enhance the information supplied by said Aerobiological Network and are aimed at allowing allergic people to take avoidance and pharmacological treatment measures. A prevalência da polinose tem vindo a aumentar nos países desenvolvidos nas últimas décadas, sendo uma doença que ocasiona um grande número de dias de absentismo laboral ou escolar, pelo que, além dos custos diretos associados à doença, determina consideráveis custos indiretos. Evitar a exposição é a medida preventiva mais eficaz. Dispor de dados aerobiológicos para áreas geográficas homogéneas permite aos doentes quer adotar medidas preventivas, quer otimizar o período do uso de medicamentos, melhorando a sua qualidade de vida. As redes aerobiológicas devem decidir a forma como disponibilizam a informação. No caso de informação destinada à população em geral é mais útil difundi-la como intervalos de concentrações ajustados a categorias de valores limite baixos, médios, altos ou muito altos, considerando que um dado numérico concreto pode não atingir o objetivo pretendido.Neste trabalho foi analisada esta informação para os dados gerados na Rede Aerobiológica da Região de Múrcia, já a partir das bases de dados aerobiológicas no período 2010-2016. Baseados na análise dos percentis 90, 95, 97 e 99 da série temporal, foram propostos valores limites, em quatro escalões (baixo, médio, alto e muito alto), para os tipos polínicos Poaceae e Urticaceae, nas cidades de Cartagena, Múcia e Lorca, visando melhorar a informação disponibilizada pela Rede Aerobiológica da Região de Múrcia, destinada a que os pacientes alérgicos empreendam medidas de redução da exposição e o tratamento farmacológico.

[EN] In the eastern Iberian Peninsula, the archaeological site of Cuesta de la Bajada (Teruel, Spain) has produced some of the earliest evidence of Middle Paleolithic stone tool traditions together with evidence of equid and cervid carcasses defleshed by hominins. Based on the numerical age of 317-240 ka derived from OSL, ESR and AAR dating methods for the lower part of the Cuesta de la Bajada sedimentological sequence (level CB3), as well as the biochronological inferences for the small and large mammal associations, the site can be attributed toMarine Isotope Stage (MIS) 8 or the end of MIS 9. As amphibians and reptiles have precise environmental and climatic requirements and do not differ at species level from the extant herpetofauna of the Iberian Peninsula, they can contribute to the reconstruction of the landscape and climate. In this paper, the fossil amphibians and squamate reptiles from Cuesta de la Bajada are studied for the first time. The mutual ecogeographic range and habitat weighting methods were applied to the herpetofaunal assemblages to estimate quantitative data for the landscape and climate reconstructions. The climate is shown to have been colder and wetter than today in the interior of eastern Spain, with mean annual temperature up to 2.5º C lower and mean annual precipitation slightly higher than at present. The monthly climatic reconstruction shows differences in the distribution of precipitation over the course of the year, with more abundant precipitation from late autumn to spring (i.e. from October to May), and more or less similar precipitation to today during the summer months (July and August). This suggests there was stronger rainfall seasonality between winter and summer than currently occurs. The paleoenvironmental reconstruction based on the herpetofaunal assemblage depicts a poorly forested (15-20%) patchy landscape with a large representation of dry meadows and scrubland habitats together with well-evidenced aquatic habitats. These reconstructions are consistent with other proxies recovered at Cuesta de la Bajada (pollen, small and large mammals) as well as other European MIS 8-9 paleoclimatic records.We can thus correlate levels CB2 and CB3 with the later part of MIS 8 (265-257 ka) or with a humid fluctuation within the MIS 9b (303-290 ka). It is also possible to provide a new description of the environmental and climatic conditions that occurred in inner Spain during a cold period of the late Middle Pleistocene.

Slowdown ,Depreciation ,Capital ,Growth ,Total Factor Productivity - Abstract
Empirical studies in macroeconomics and economic growth literature are highly dependent on the measure of the physical capital stock. The variables that contribute to explain the major problems in these areas of research always appear related, whether directly or indirectly, to capital stock and depreciation. The standard measurements of capital and depreciation are statistical measures based on assumptions about the average service life of capital goods, which are accumulated according to the perpetual inventory method. In this paper we propose an alternative method based on the equations that solve the dynamic optimization problem of the neoclassical firm. This method enables us to endogenously calculate the variables rate of depreciation and capital stock, yielding an economic estimation based on indicators of profitability such as the distributed profits and the Tobin's q ratio. This represents a change of paradigm in measuring capital and depreciation, which we supply along with an application to the Spanish economy. The results show an economic depreciation rate (endogenous) that fluctuates around the statistical rate (exogenous), and two time profiles for the economic and statistical capital stocks that are markedly different. In the context of a growth accounting exercise we show how capital intensity and total factor productivity play different roles in explaining growth over the past fifty years, depending on whether we are using statistical or economic measures. Finally, we analyze the paradox of productivity and conclude that the absence of positive correlation between investment in information and communication technologies and the rate of growth of total factor productivity may be due to a combination of the delay effect associated with such investment and the under-estimation of the true economic depreciation.

- Abstract
In vitro transposition is a powerful genetic tool for identifying mycobacterial virulence genes and studying virulence factors in relation to the host. Transposon shuttle mutagenesis is a method for constructing stable insertions in the genome of different microorganisms including mycobacteria. Using an IS1096 derivative, we have constructed the Tngfp, a transposon containing a promoterless green fluorescent protein (gfp) gene. This transposon was able to transpose randomly in Mycobacterium bovis BCG. Bacteria with a single copy of the gfp gene per chromosome from an M. bovis BCG::Tngfp library were analyzed and cells exhibiting high levels of fluorescence were detected by flow cytometry. Application of this approach allowed for the selection of a mutant, BCG_2177c::Tngfp (BCG-Tn), on the basis of high level of long-standing fluorescence at stationary phase. This BCG-Tn mutant showed some particular phenotypic features compared to the wild type strain, mainly during stationary phase, when cholesterol was used as a sole carbon source, thus supporting the relationships of the targeted gene with the regulation of cholesterol metabolism in this bacteria. This approach showed that Tngfp is a potentially useful tool for studying the involvement of the targeted loci in metabolic pathways of mycobacteria.

The main objective of this work is to know the perception of the undergraduate and master students of the three Galician universities about the plagiarism commission and check the relationship between it and the citation of documentary sources as a criterion for the evaluation of academics works by teachers of the different knowledge areas. The sample is made up of 8.943 students, with an approximate average age of 21 years, approximately 66% of women and from all knowledge areas. To collect the information, the Questionnaire for the Detection of Coincidences in Academic Work (QUDECO) is used. The data indicates that students have a lower predisposition to commit plagiarism in the event that teachers take action on it in the evaluation process. In conclusion, it is possible to establish a greater need for research about the characteristics of evaluation systems and, consequently, also about the characteristics of the teaching-learning process.

- Abstract
The incidence of pollinosis in developed countries has been on the rise for the past few decades. It is an illness that leads to a large number of missed work and school days. Therefore, in addition to the direct costs associated therewith, it also causes significant indirect costs. Avoidance to exposure is the most effective preventive measure. With aerobiological data for homogeneous geographical areas, sick people can both take preventive measures and optimize the period of usage of drugs and thus improve the quality of their life. Aerobiological networks have to decide how to provide this information. In the case of information intended for the general public, it is more useful to give it as concentration ranges adjusted to categories of low, medium and high/very high threshold values than as specific numerical values, which might not achieve the desired goal.In this paper we have analyzed the data generated by the Aerobiological Network of the Region of Murcia, Spain, from aerobiological databases in the 2010-2016 period. Based on the analysis of the 90, 95, 97 and 99 percentiles of the time series, we have proposed threshold values —in four levels (low, medium, high and very high), for the Poaceae and Urticaceae pollen types in the towns of Cartagena, Lorca and Murcia— that enhance the information supplied by said Aerobiological Network and are aimed at allowing allergic people to take avoidance and pharmacological treatment measures., La prevalencia de la polinosis está aumentando en los países desarrollados en las últimas décadas, siendo una enfermedad que ocasiona un gran número de días de pérdida de actividad laboral o de asistencia a la escuela, por lo que, además de los costes directos ligados a la enfermedad, ocasiona importantes costes indirectos. La evitación de la exposición es la medida preventiva más eficaz. El disponer de datos aerobiológicos para áreas geográficas homogéneas permite a los enfermos, tanto poner en marcha medidas preventivas, como optimizar el periodo de uso de medicamentos y mejorar la calidad de vida. Las redes aerobiológicas deben decidir el modo en que suministra la información. En el caso de información destinada a la población general, es más útil difundirla como intervalos de concentraciones ajustados a categorías de valores umbrales bajos, medios, altos o muy altos, que a un dato numérico concreto que puede no alcanzar el objetivo perseguido.En este trabajo hemos analizado esta información para los datos generados en la Red Aerobiológica de la Región de Murcia y a partir de las bases de datos aerobiológicas del periodo 2010-2016 hemos propuesto, basado en el análisis de los percentiles 90, 95, 97 y 99 de la serie temporal, unos valores umbrales, en cuatro escalones, bajo, medio, alto y muy alto para los tipos polínicos Poaceae y Urticaceae en la ciudades de Cartagena, Murcia y Lorca, que mejoran la información suministrada por la Red Aerobiológica de la Región de Murcia encaminada a que los pacientes alérgicos emprendan las medidas de evitación y el tratamiento farmacológico., A prevalência da polinose tem vindo a aumentar nos países desenvolvidos nas últimas décadas, sendo uma doença que ocasiona um grande número de dias de absentismo laboral ou escolar, pelo que, além dos custos diretos associados à doença, determina consideráveis custos indiretos. Evitar a exposição é a medida preventiva mais eficaz. Dispor de dados aerobiológicos para áreas geográficas homogéneas permite aos doentes quer adotar medidas preventivas, quer otimizar o período do uso de medicamentos, melhorando a sua qualidade de vida. As redes aerobiológicas devem decidir a forma como disponibilizam a informação. No caso de informação destinada à população em geral é mais útil difundi-la como intervalos de concentrações ajustados a categorias de valores limite baixos, médios, altos ou muito altos, considerando que um dado numérico concreto pode não atingir o objetivo pretendido.Neste trabalho foi analisada esta informação para os dados gerados na Rede Aerobiológica da Região de Múrcia, já a partir das bases de dados aerobiológicas no período 2010-2016. Baseados na análise dos percentis 90, 95, 97 e 99 da série temporal, foram propostos valores limites, em quatro escalões (baixo, médio, alto e muito alto), para os tipos polínicos Poaceae e Urticaceae, nas cidades de Cartagena, Múcia e Lorca, visando melhorar a informação disponibilizada pela Rede Aerobiológica da Região de Múrcia, destinada a que os pacientes alérgicos empreendam medidas de redução da exposição e o tratamento farmacológico.

- Abstract
[EN] The Shelter of Benzú is located near the city of Ceuta, in North Africa. We are currently working on the final stage of the scientific report of the activities carried out in the last years. We have done an evaluation, although still not final, of geological, stratigraphic, chronological, and ecological data as well as the different resources used by prehistoric societies. We emphasize the technological data for the archaeological products and for lifestyles. Geological and paleoecological bases of the historical region of the Strait of Gibraltar provide great similarities between the European and North African shores. The shelter of Benzú has a sequence of seven archaeological levels with a clearly defined technology belonging to Mode 3 concept. The similarities with the sets of the southern Iberian Peninsula are evident. We also emphasize the exploitation of marine resources by hunter-gatherer societies since the beginning of the Middle Pleistocene sequence. With these archaeological bases and the context of recent studies in the North African region, we value the possible relationships and contacts between societies on both sides of the historical region of the Strait of Gibraltar., [FR] L’abri de Benzú est situé dans la ville de Ceuta, en Afrique du Nord. Nous apportons ici un bilan sur la géologie, la stratigraphie, la chronologie, l’écologie et les ressources utilisées par les sociétés préhistoriques de ce site. Nous mettons l’accent sur les données technologiques issues du mobilier archéologique et sur les modes de vie. Les fondements géologiques et paléo-écologiques de la région historique du détroit de Gibraltar offrent de grandes similitudes entre les rives africaine et européenne de cet espace. L’abri de Benzú dispose d’une séquence de sept couches stratigraphiques en relation avec un faciès technologique précis qui renvoie au Mode 3-Paléolithique moyen. Les similarités avec les contextes appartenant au Sud de la péninsule Ibérique sont significatives. De plus, nous souhaiterions souligner l’exploitation des ressources marines par les sociétés de chasseurs-cueilleurs, depuis le début de la séquence stratigraphique au cours du Pléistocène moyen. Avec cet ensemble de données archéologiques et le cadre offert par des études récentes sur ce secteur du Nord de l’Afrique, nous tentons d’évaluer les relations et contacts possibles entre les deux rives de la région géo-historique du détroit de Gibraltar.

Abrigo de Benzú (Ceuta) ,Sociedades cazadoras-recolectoras-recolectoras de productos marinos ,Yacimientos arqueológicos - Abstract
Síntesis de una década de trabajo a los estudios en el Abrigo de Benzú donde se muestran el interés, y el futuro de este significativo yacimiento. Se destaca la aportación de una gran cantidad de información y el nivel de conocimientos alcanzado. Se presenta un estudio que representa «mucho más que piedras». Los registros arqueológicos pertenecientes a sociedades cazadoras-recolectoras-recolectoras de productos marinos alcanzan ahora con esta obra y con otros estudios en la región gran interés, llegando a formar parte de las señas de identidad de la región geohistórica del estrecho de Gibraltar, que cuenta con un rico patrimonio histórico. El Abrigo de Benzú contribuye al avance en la fijación estratigráfica de los depósitos arqueológicos, en la aportación de cuadros cronológicos, en desarrollos de estudios geológicos, faunísticos, medioambientales, tecnológicos, así como en la formulación de hipótesis en el marco económico y social. Los estudios en el Abrigo de Benzú durante la última década han confirmado claramente la necesidad de poder realizar investigación con continuidad de los proyectos, y que sigue siendo fundamental contar con el apoyo normalizado de las administraciones con competencias en la materia.

El estudio interdisciplinar aplicado a la Cueva de Benzú ha posibilitado la inferencia de numerosos datos de gran interés para avanzar en el conocimiento de las formaciones sociales tribales en el área norteafricana. Se han efectuado campañas de excavación durante los años 2002, 2003, 2004, 2005 y 2007, interviniéndose en un total de 21 cuadrículas de 1 × 1 metro, que corresponden a una superficie total aproximada de 19 metros cuadrados. Se ha seguido el denominado sistema alternante de excavación (Arteaga, Ramos y Roos, 1998), con el objetivo de inferir posibles áreas de actividad. Aspiramos a la reconstrucción de los procesos de producción y consumo y al conocimiento de los modos de vida desarrollados por estas sociedades que ocuparon la cueva.

The chemical data of major elements is used to study the precise lithological composition and the sedimentology of Miocene diatomaceous sediments from 24 sections of the Guadalquivir Basin. Three main episodes (Lower, Middle and Upper), defined on the basis of diatom zones have been studied. They record a highly productive coastal upwelling regime in the area during the Miocene. The wide range of variation of SiO2 (12.1878.00), CaO (1.60-43.73) and Al2O3 (2.76-10.32) contents reflects the important variations of the main components: Opal A, calcite (mainly biogenic) and clay minerals-terrigenous components. Biogenic silica has been estimated by using normative calculations after determination of the mineralogical compositions of the samples by means of X-ray diffraction. Maximum and minimum contents in biogenic silica are related to the dominant diatom taxa, the structure of the rock and the geographicallocation in the basin. The ternary diagrams SiO2 biogenic- Al2O3-CaO reveal that the Upper Episode has the highest amounts of clay minerals-terrigenous components. Plots of SiO2 biogenic/CaO versus Al2O3show a relation between the biogenic calcite and the clay-minerals-terrigenous components. The plots of Fe2O3/TiO2 versus Al2O3/ Al2O3+ Fe2O3 show that most of the samples may be interpreted as deposited in a continental margin enviranment. The data obtained fram the slope of linear regressions Fe (y) - Al (x) are indicative of areas with varying influence of a terrigenous source. The MnO/ Al2O3 ratio is used to estimate rates of sedimentation of the diatomaceous sediments. The range is between 1.7 and 180 mm/103 years, which is consistent with the sedimentation rate values fram sediments formed in coastal upwelling regimes. The rate of sedimentation varies in relation to the structure of the rack, the dominant diatom taxa and the age of the episodes.La composición química de elementos mayores es utilizada para analizar las características composicionales y sedimentológicas en 24 afloramientos de sedimentos miocenos con diatomeas de la Cuenca del Guadalquivir. En función de las biozonas de diatomeas, se consideran tres episodios de sedimentación diatomítica (Inferior, Medio y Superior) que reflejan un medio de sedimentación de alta productividad biogénica ocasionada por corrientes ascensionales costeras («coastal upwelling»). Los grandes márgenes de variación de los tres óxidos más importantes SiO2 (12,1878,00), CaO (1,60-43,73) y Al2O3 (2,76-10,32) definen la gran variación que presentan los tres componentes mayoritarios de estos sedimentos: Opalo A, calcita y minerales de la arcilla-terrígenos. A través de cálculos normativos en función de la composición mineralógica de las muestras y de los análisis de difracción de RX, se ha definido el porcentaje de sílice biogénica. El estudio de los máximos y mínimos de sílice biogénica ha puesto de manifiesto su relación con tipos dominantes de diatomeas, la estructura de la roca y la posición geográfica dentro de la Cuenca. La proyección de las muestras en los diagramas triangulares SiO2 biogénica- Al2O3-CaO ha revelado que el Episodio Superior es el que manifiesta mayor proporción relativa de Al2O3 (arcillas-componentes terrígenos). Los diagramas SiO2 biogénicalCaO versus Al2O3 han demostrado que existe frecuentemente una asociación preferente entre el plancton calcáreo y los minerales de arcilla-terrígenos. La proyección de las muestras en el diagrama Fe2O3/TiO2 versus Al2O3/ Al2O3+FeO, junto con la pendiente de la recta de regresión Fe (y) - Al (x) indican que todas las series se pueden considerar de plataforma continental existiendo zonas con mayor o menor influencia del continente. La relación MnO/ Al2O3, se ha utilizado para medir la tasa sedimentación; los valores obtenidos (entre 1,7 y 180 mm/103 años) concuerdan con los hallados en otras zonas de corrientes ascensionales costeras, encontrándose diferencias en función de las estructura de la roca, las diatomeas dominantes y los episodios considerados.

- Abstract
Esquilleu cave (Cantabria, northern Spain) presents 30 Mousterian archaeological layers covering virtually the complete MIS 3 both in chronology and environmental. A number of environmental analyses (faunal, pollen, charcoal) allow the study of the different strategies for the procurement and management of resources available near the site and indicate the Neanderthals’ wide adaptability to the changing environment typical of this period. This paper also discusses the possibility of using bones as fuel either as a palliative for a presumed lack of wood resources in the environment or as a mere pattern of human behaviour., Resumen: La cueva del Esquilleu (Cantabria, norte de España) presenta 30 capas arqueológicas musterienses que cubren prácticamente todo el MIS 3 tanto en cronología como en medio ambiente. Una serie de análisis ambientales (fauna, polen, carbón vegetal) permiten el estudio de las diferentes estrategias para la adquisición y gestión de los recursos disponibles cerca del yacimiento e indican la amplia adaptabilidad de los neandertales a los cambios del entorno típico de este período. Este trabajo también analiza la posibilidad de utilizar los huesos como combustible, ya sea como un paliativo para una supuesta falta de recursos de madera en el medio ambiente o como un simple patrón de comportamiento humano.

Las hemorragias intracraneales pueden ser espontáneas o traumáticas. Las hemorragias intracerebrales espontáneas constituyen el 5-19% de todos los ictus, se presentan sobre todo en la edad media de la vida, sin una clara predominancia por sexos. Suele ser la manifestación de una enfermedad vascular cerebral subyacente, siendo la hipertensión arterial el factor de riesgo más importante. Otros factores predisponentes son la diabetes, el alcoholismo o el tabaquismo. Los traumatismos craneoencefálicos también pueden causarlas. Las hemorragias hipertensivas intraparenquimatosas suelen localizarse anatómicamente en el putamen (60% de los casos), tálamo, puente cerebral, hemisferios cerebelosos (rara vez) y en otras regiones del cerebro. La hipertensión arterial y los angiomas cavernosos son las causas más frecuentes. Estas hemorragias son graves y pueden causar la muerte instantánea o de forma rápida en personas sin antecedentes conocidos, en cuyo caso se incluyen en el concepto médico de muerte súbita, y legal de 'sospechosa de criminalidad', de modo que se les practica la autopsia judicial para conocer entre otros, la causas y circunstancias de la muerte. Presentamos tres casos de muerte súbita en adultos causadas por hemorragias intracraneales. En dos casos el sangrado fue espontáneo y se localizó en el tronco de encéfalo o Puente de Varolio; en el tercero, se encontró una hemorragia en el mesencéfalo, que se consideró secundaria y de etiología traumática. Intracranial hemorrhages can be spontaneous or traumatic. Spontaneous intracerebral hemorrhages constitute 5-19% of all strokes, are mostly in the middle age of life, with no clear gender predominance. It is often a manifestation of underlying cerebrovascular disease, hypertension being the most important risk factor. Other predisposing factors include diabetes, alcoholism or smoking. Head injuries can also cause them. Hypertensive intraparenchymal hemorrhages usually located anatomically in the putamen (60% of cases), thalamus, cerebral bridge, cerebellar hemispheres (rarely) and in other brain regions. Hypertension and cavernous angiomas are the most common causes. These hemorrhages are serious and can cause instant death or quickly in people with no known history, in which case they are included in the concept of sudden death medical, legal and "suspected crime" so they were necropsied court to hear among others, the causes and circumstances of death. We present three cases of sudden death in adults caused by intracranial bleeding. In two cases the bleeding was spontaneous and was located in the brain stem or Pons, in the third, was found bleeding in the midbrain, which was considered secondary and traumatic etiology.

The lithological composition and biostratigraphy of diatomaceous marls have been defined in 93 outcrops of the Guadalquivir Basin. The diatomaceous marls display a wide variety of lithological types, mainly comprised of opal A (10-85 %) (mainly diatoms and to a lesser extent silicoflagellates, spicules and radiolarians), calcite (5-80 %) (principally foraminifers, nannoplankton, sparite, micrite and microspar), c1ay minerals (5-40 %) (smectite in greater quantities than illite; and kaolinite in small quantities) and terrigenous quartz (< 15 %). The diatom assemblages in the marls reflect the occurrence of temperate to warm water conditions in this area during middle and late Miocene. The diatoms are dominated by the fol1owing upwelling species: Thalassiosira nitzshoides, Thalassiotrix longuissima and Thalassionema baci//aris. Benthic diatoms are scarce but they have great species diversity. However, in sorne outcrops the genus Delphineis is more frequent thus indicating environments c10ser to shore areas. Three episodes based on Barron's (1985) low latitude zonation have been defined. The Lower Episode includes Cestodiscus peplum and Coscinodiscus lewisianus Zone and is assigned to the upper Langhian- lower Serravalian. After a period of no diatom occurrence (e. gigas var. diorama Zone is missing), the Middle Episode is defined by Craspedodiscus coscinodiscus and Actinocyclus moronensis Zones and covers the latest Serravalian-early Tortonian. The Upper Episode corresponds to Thalassiosira yabei Zone and it is assigned to middle Tortonian. The fundamental types of dilutants in diatomic sedimentation (biogenic calcareous, terrigenous and c1ay minerals), do not vary throughout the three episodes but there are great variations in the proportions. The coastal upwelling regime produces tongue-like patterns of sedimentation and the sedimentary record displays different changes of facies. The Upper Episode, where the c1ay-terrigenous dilutants predominate over calcareous dilutants and Delphineis appear in greater quantities, is interpreted as having been formed in an environment closer to the shore than other episodes. El estudio de 93 puntos en el Mioceno de la cuenca del Guadalquivir ha permitido definir en esta cuenca la situación, bioestratigráfica y composición litológica de las margas con diatomeas o «moronitas». Dichas rocas incluyen gran variedad de términos litológicos estando constituidos principalmente por ópalo A (10-85 %) (mayoritariamente diatomeas; silicoflagelados, espículas de esponja y radiolarios en menor proporción), calcita (5-80 %) (microforaminíferos, nanoplancton calcáreo, micrita y esparita fundamentalmente), minerales de la arcilla (5-40 %) (esmectita predominando sobre illita y caolinita en menores proporciones) y cuarzo terrígeno « 15 %). Las asociaciones de diatomeas están constituidas fundamentalmente por diatomeas planctónicas de aguas templado-cálidas, con dominio de Thalassionema nitzschoides, Thalassionema bacillaris y Thalassiotrix longuissima, definiendo áreas de alta productividad (upwelling) en la zona durante el Mioceno Medio y Superior. El componente bentónico es escaso y diversificado, sin embargo localmente adquiere importancia el género Delphineis indicando zonas más litorales. Se determinan tres episodios de sedimentación diatomítica basados en la zonación de baja latitud de Barron (1985c). El Episodio Inferior definido por las biozonas Cestodiscus peplum y Coscinodiscus lewisianus, comprende desde el Langhiense superior al Serrava¡ iense inferior. Después de un período de tiempo sin deposición de diatomeas comienza el Episodio Medio definido por las biozonas Craspedodiscus coscinodiscus y Actinocyclus moronensis, y que incluye el techo del Serravaliense y el Tortoniense Inferior. El Episodio Superior que corresponde a la biozona Thalassiosira yabei comprende el Tortoniense Medio. Los tipos de diluyentes fundamentales de la sedimentación diatomítica (componentes biogénicos calcáreos, terrígenos y arcillas), se mantienen en los tres episodios pero presentan gran variación en sus proporciones debido a la morfología «en lenguas» y composición de los depósitos sedimentarios formados bajo zonas de «coastal upwelling». El Episodio Superior diferenciado por el predominio del diluyente arcilloso-terrígeno y por una mayor proporción de Delphineis en las asociaciones de diatomeas. se interpreta formado más cerca del continente.
