The Paleolithic in the Palentina mountain: state of the art and new contributions

Este artículo expone un estado de la cuestión sobre las investigaciones del Paleolítico en la Montaña Palentina a través del estudio de las industrias líticas. Las nuevas investigaciones llevadas a cabo en el alto Pisuerga, por el Proyecto de investigación OCUPAP, permiten aportar nuevos datos sobre el poblamiento paleolítico de este territorio, donde se ha llevado a cabo una intensa labor de prospección arqueológica tanto en lugares al aire libre como en los espacios subterráneos. Los resultados de estos trabajos han permitido localizar 17 nuevos yacimientos o localizaciones de Paleolítico Antiguo con industrias líticas elaboradas fundamentalmente en cuarcitas y, en el caso de las cuevas, también con algunos restos faunísticos. Por lo que se refiere al componente lítico, encontramos ejemplos de series muy pequeñas con apenas unas piezas sueltas, frente a otros conjuntos con miles de elementos, por lo que la representación de las cadenas operativas también es variada. En general, la caracterización tecnotipológica nos ha permitido identificar yacimientos asimilables a los tecnocomplejos achelenses, siempre en las terrazas fluviales del río (Terraza Salinas, Parcelas Grava, etc.), con un elevado valor de los grupos bifaciales. Y, por otro lado, tenemos un buen número de series claramente de Paleolítico medio, también al aire libre (Areniscas, Ligüérzana, terraza Allende, etc), además de niveles de ocupación humana musterienses en las cuevas Peña de Mudá I y Allende.This paper presents a state of the art on Palaeolithic research in the Palentina Mountains through the study of lithic industries. The new research carried out in the upper Pisuerga, by the OCUPAP research project, provides new data on the Palaeolithic settlement of this territory, where intense archaeological prospection work has been carried out both in open-air sites and in underground spaces. The results of this work have made it possible to locate 17 new Early Palaeolithic sites or locations with lithic industries made mainly from quartzite and, in the case of the caves, also with some faunal remains. As far as the lithic component is concerned, we find examples of very small series with only a few single pieces, as opposed to other assemblages with thousands of elements, so that the representation of the operational chains is also varied. In general, the techno-typological characterisation has allowed us to identify sites comparable to Acheulean technocomplexes, always on the fluvial terraces of the river (Salinas Terrace, Parcelas Grava, etc.), with a high value of bifacial groups. And, on the other hand, we have a good number of series clearly from the Middle Palaeolithic, also in the open air (Areniscas, Ligüérzana, Allende terrace, etc.), as well as levels of Mousterian human occupation in the Peña de Mudá I and Allende caves

Cirugía preservadora de órgano tras traumatismo esplénico cerrado con implicación hiliar

ResumenAntecedentesLa afectación esplénica secundaria a un traumatismo abdominal cerrado es frecuentemente tratada mediante esplenectomía. Ante la gravedad de las consecuencias del síndrome postesplenectomía (pérdidas hemáticas, sepsis, etc.) cada vez se tiende más a la preservación del órgano afectado. Presentamos un caso clínico de preservación de bazo tras traumatismo abdominal cerrado con implicación hiliar de dicho órgano, en el que se recurre al papel esencial del Floseal® como agente hemostático.Caso clínicoMujer de 22 años que presenta traumatismo abdominal cerrado tras accidente de tráfico, con diagnóstico de lesión esplénica del polo inferior con compromiso hiliar que implica la vascularización de dicha región. Se procede a la intervención quirúrgica urgente con preservación esplénica mediante esplenectomía parcial y control del sangrado con Floseal® y con el empleo de una malla de refuerzo de ácido poliglicólico. La evolución postoperatoria es satisfactoria y sale del hospital al 5.o día sin incidencias.ConclusiónEl empleo de agentes hemostáticos como el gel de gelatina y trombina (Floseal®) y el uso de mallas envolventes de ácido poliglicólico posibilitan la cirugía de preservación esplénica tras un traumatismo abdominal, representando una alternativa segura y factible a la esplenectomía completa clásica, con el beneficio de la conservación del órgano y de sus funciones.AbstractBackgroundSplenic involvement secondary to blunt abdominal trauma is often treated by performing a splenectomy. The severity of the post-splenectomy syndrome is currently well known (blood loss, sepsis), so there is an increasing tendency to preserve the spleen. The case is presented of splenic preservation after blunt abdominal trauma with hilum involvement, emphasising the role of Floseal® as a haemostatic agent, as well as the use of resorbable meshes to preserve the spleen.Clinical caseA 22-year-old woman presenting with a grade IV splenic lesion secondary to a blunt abdominal trauma after a traffic accident. Partial splenic resection was performed and bleeding was controlled with Floseal® and use of a reinforcing polyglycolic acid mesh. No postoperative complications occurred, being discharged on day 5. The long-term follow-up has been uneventful.ConclusionThe use of haemostatic agents such as thrombin and the gelatine gel (FloSeal®) and the use of polyglycolic acid meshes enable spleen-preserving surgery, making it a feasible and reproducible procedure and an alternative to classical splenectomy

Control and soft sensing strategies for a wastewater treatment plant using a neuro-genetic approach.

During the last years, machine learning-based control and optimization systems are playing an important role in the operation of wastewater treatment plants in terms of reduced operational costs and improved effluent quality. In this paper, a machine learning-based control strategy is proposed for optimizing both the consumption and the number of regulation violations of a biological wastewater treatment plant. The methodology proposed in this study uses neural networks as a soft-sensor for on-line prediction of the effluent quality and as an identification model of the plant dynamics, all under a neuro-genetic optimum model-based control approach. The complete scheme was tested on a simulation model of the activated sludge process of a large-scale municipal wastewater treatment plant running under the GPS-X simulation frame and validated with operational gathered data, showing optimal control performance by minimizing operational costs while satisfying the effluent requirements, thus reducing the investment in expensive sensor devices

Improvement of teaching, learning and english usage: common errors (F)

Se ha desarrollado el programa iErrors-F, disponible a modo de juego para aprender los errores comunes del uso del inglés (F) en . Dicho proyecto (2015-2-2009) complementa otros nueve (07NA2037, 08A4087, 092016, 102008, 112007, 122022, 2013-12-2009, 2014-12-2013 y 2016-1-2009), que permitieron desarrollar, respectivamente, los programas iFalseFriends, iPartialFalseFriends, iAnglicisms, iErrors-A, iErrors-B, iErrors-C, iErrors-D, iErrors-E and iErrors-G, disponibles a modo de juego para aprender los “falsos amigos” o cognados entre inglés y español , los “amigos inconsistentes” o cognados parciales entre dichos idiomas , los anglicismos , los errores comunes en inglés (A) , los errores comunes en inglés (B) , los errores comunes en inglés (C) , los errores comunes en inglés (D) los errores comunes en inglés (E) y los errores comunes en inglés (G) . Conviene resaltar que estos desarrollos se basan en el aprendizaje de forma lúdica, mediante un juego educativo, lo cual potencia su uso por todos en general y por las nuevas generaciones en particular. Esto diferencia a estos desarrollos de otras alternativas, como son las listas de textos escritos o diccionarios existentes. Dicho con otras palabras, el objetivo es innovar desde el diccionario clásico al juego educativo. Consideramos que ello es un elemento clave para incentivar y motivar al posible usuario. Dichos juegos educativos están diseñados para una visualización óptima desde el navegador web Apple Safari con iPhone e iPod touch (también se pueden usar en el iPad, así como con Mac o Windows). Es indudable que el inglés es el idioma universal y la lingua franca de nuestros días. Sin embargo, el nivel general de inglés en la Universidad de Córdoba puede ser significativamente mejorado, incluyendo Personal Docente e Investigador (PDI), alumnos y Personal de Administración y Servicios (PAS). Esta realidad puede extrapolarse a Andalucía y a España entera. Se trata de un hecho de notable importancia, sobre todo si se tiene en cuenta que la tendencia progresiva es hacia la impartición de clases en inglés. Por tanto, la situación actual nos pone en desventaja frente al proceso de Convergencia Europea (ECTS/EEES), la competitividad empresarial y el acceso al mercado laboral de nuestros egresados, por citar sólo algunos ejemplos. Esta realidad cobra especial relevancia en un mundo cada vez más globalizado. Faltan, por otra parte, herramientas específicas de enseñanza, aprendizaje, uso y perfeccionamiento del inglés (con aplicación académica general, docente, investigadora, asistencial y de gestión) que incidan en las peculiaridades de los hispanoparlantes en general y de los universitarios en particular. El proyecto realizado ha usado las nuevas Tecnologías de la Información y la Comunicación (TIC) para el desarrollo y aplicación de herramientas multimedia y multiplataforma que ayuden a mejorar dichas carencias. El programa contiene una base de datos de errores comunes en el uso del inglés (F). El funcionamiento del recurso es tan intuitivo que no requiere instrucciones especiales: basta navegar hasta iErrors-F y seguir las instrucciones del juego educativo que aparecen en pantalla. La metodología utilizada es doble. Por una parte, se ha desarrollado dicho programa a modo de juego de aprendizaje para su acceso universal vía Internet. Por otra parte, los alumnos han jugado con el mismo de forma presencial y no presencial, analizándose después en clase los avances alcanzados en el aprendizaje del inglés, mediante las correspondientes evaluaciones de progreso. Con ello se ha conseguido una significativa mejora en el aprendizaje de inglés de los alumnos, en un campo en el que los propios angloparlantes cometen errores. El uso de esta herramienta permite una mejora de la docencia, aprendizaje y uso de dicho idioma, mejorando también con ello la calidad de las diferentes actividades desarrolladas en la universidad: académica general, docente, investigadora, asistencial y de gestión. De este modo se contribuye a aumentar la competitividad de la universidad, preparando a la misma para una mejor adaptación al Sistema de Convergencia Europea, actualizando la docencia en las nuevas tecnologías y mejorando la formación pedagógica del profesorado. Asimismo, todo ello genera un perfil más internacional y abierto de nuestra universidad, incrementando su calidad, y con ello el número de alumnos y profesores que la elijan.The application iErrors-F has been developed, being available as a game to learn common errors in English usage (F) in . Such project (2015-2-2009) complement other nine (07NA2037, 08A4087, 092016, 102008, 112007, 122022, 2013-12-2009, 2014-12-2013 and 2016-1-2009), which allowed to develop, respectively, the applications iFalseFriends, iPartialFalseFriends, iAnglicisms, iErrors-A, iErrors-B, iErrors-C, iErrors-D, iErrors-E and iErrors-G, available as games to learn “false friends” or cognates between English and Spanish , “inconsistent friends” or partial cognates between such languages , anglicisms , common errors in English (A) , common errors in English (B) , l common errors in English (C) , common errors in English (D) , common errors in English (E) and common errors in English (G) . It is important to remark that these developments are based on ludic learning, by means of educational games (edutainment), which enhance their use by all in general, and the new generations in particular. That sets apart these developments from other alternatives, like lists of available written texts or dictionaries. In other words, the objective is to innovate from classic dictionaries to educational games. We consider that this is a key element to encourage and motivate the potential user. Such educational games are designed for an optimal visualization from Apple Safari web browser, with iPhone and iPod touch (they can be also used with iPad, as well as Mac o Windows). It is obvious that English is the universal langue and lingua franca of our days. Yet, the general English level at the University of Cordoba (including faculty, students and administrative staff) can be significantly improved. This situation can be extrapolated to Andalusia and the whole Spain. That is a critical fact, mainly when taking into account that there is a progressive trend towards lecturing in English language. Therefore, the current situation represents a disadvantage for us in the context of European Convergence [European Credit Transfer and Accumulation System (ECTS)/European Higher Education Area (EHEA)], business competitiveness and access to labor market of graduates, among others. This situation takes special relevance in a world that is becoming globalized. On the other hand, there is a lack of specific tools for teaching, learning, use and improvement of English language (with general academic application, education, research, assistance and management), taking into account the Spanish-speaking people in general, and university students in particular. The project carried out has used the new Information and Communication Technologies (ICT) for development and deployment of multimedia and cross-platform tools to help improve such shortcomings. The application contains a database of common errors of English usage (F). Operation of the resource is so intuitive that it does not require special instructions: just navigate to iErrors-F and follow the simple directions of the edutainment game, showing on the screen. The methodology used is twofold. On one side, such application has been developed as a learning game for universal access via Internet. On other side, students have played with it in classrooms and outside locations (distance-learning), analyzing later on in classrooms the goals reached in English learning, by means of corresponding progress assessments. That has allowed to accomplish a significant improvement in English learning of students, in an area in which even English-speaking people make mistakes. Such tool allows an improvement of lecturing, learning and usage of such language, further improving that way the quality of different activities carried out at the university: academic in general, education, investigation, assistance and management. This is, therefore, a contribution to increase the university competitiveness, training for a better adaptation to the European Convergence System, updating teaching in new technologies and improving pedagogical level of teachers. Additionally, all that generates a more international and open profile of our university, increasing its quality, and thus the number of students and teachers applying for it

Worldwide trends in underweight and obesity from 1990 to 2022 : a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

A list of authors and their affiliations appears online. A supplementary appendix is herewith attached.Background: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods: We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI 2 SD above the median). Findings: From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation: The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesity.peer-reviewe

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions
