The Sustainable Management of Metals: An Analysis of Global Research

The objective of this study was to analyze research trends in the field of sustainable management of metals on a global level between 1993 and 2017. To do so, a bibliometric analysis was carried out on a total of 6967 articles. The results revealed the growing interest in this research field, particularly over the last five year-period during which 63% of all articles were published. The three journals in which most articles had been published were the Journal of Cleaner Production, ACS Sustainable Chemistry and Engineering, and Chemsuschem. The countries that published the most articles were China, the United States, India, Germany, and the United Kingdom. A sizeable network of collaboration has been established between countries for the joint publication of studies. The main lines of research have been focused on metal decontamination in water and soil, waste management oriented towards reuse and recycling, and the innovation of processes for cleaner and more efficient production. The results revealed the need for comprehensive studies that integrate different disciplines within the same analytical framework, and to promote research that contributes to the different dimensions of sustainability (environmental, economic, and social)

Satisfacción del cliente por medio de innovación apoyada en tecnologías móviles

40 páginasLas filas, en general son algo que no le gusta a la gente, sin embargo, para muchos temas sociales son necesarias, en particular si hablamos de eventos de entretenimiento como funciones de cine, obras de teatro e incluso conciertos musicales, los espectadores en general se ven obligados a hacer filas para adquirir o reclamar sus boletas fisicas, y luego generalmente para ingresar a los eventos debes hacer nuevamente una fila. El objetivo es mejorar la experiencia de los clientes implementando procesos innovadores que cambien la forma en la que actualmente acceden a este tipo de eventos, en principio se buscara eliminar la necesidad de hacer filas para adquirir la boletería, este proceso entregará una boleta electrónica que evitara que el cliente deba hacer una nueva fila para reclamar su boleta fisica, esto ya aporta mejoras en el tiempo que debe invertir el cliente para adquirir y obtener su boleta. Seguido a esto se implementará un método novedoso y ágil que permita la validación y entrada rápida de los usuarios a los eventos en los que se utilice ésta tecnología, motivando un incremento en el uso y asistencia a estos servicios.The rows in general are something that people do not like, however, far many social issues are needed, particularly if we talk about entertainment events like film roles, plays and even musical concerts, viewers in general Are forced to make rows to acquire their physical tickets, and then generally to get into the events you must make a row again. The objective is to improve the customer experience by implementing innovative processes that change the way they currently access these shows, at first we will seek to eliminate the need to make a row to purchase the ticket, this process will deliver an electronic ticket that would avoid That the client must make a new row to claim his physical ticket, this already provides improvements in the time that the client must invest to acquire and obtain bis ticket. Following this will be implemented a novel and agile method that allows the validation and rapid entry of users to the events in which this technology is used, motivating an increase in the use and assistance to these services.Especialista en Gerencia y Tecnologías de InformaciónEspecializació

Conferencia: Secciones condensadas y máximos transgresivos. Una relación equívoca

El método analítico de la estratigrafía secuencial permite aclarar la organización espacio-temporal de los depósitos en las cuencas sedimentarias. Sin embargo, la distribución relativa de las inconformidades y de las secciones condensadas no puede seguir siendo utilizada como criterio diagnóstico de una localización paleogeográfica particular, o de cambios eustáticos hacia condiciones más oceánicas o de mayor profundidad, en relación con etapas de máxima transgresión regional. [ABSTRACT] Sequence stratigraphy allows to elucida te the time-space organization of the deposits in the sedimentary basins. However, the relative distribution of the unconformities as well as of the condensed sections can neither be used as a diagnostic criteria for a particular paleogeographic setting, nor as an indicator of eustatic changes towards deeper conditions related to maximum regional transgressions. Condensation processes can occur during maximum transgressive stages in the distal portion of the basins, but condensation processes are also present along maximum regression stages in the shallowest portions of the platforms. Condensed sections are not only related to the maximum flooding surfaces but also to the systems tracts generated under low sea level conditions. The stratigraphic, sedimentary and taphonomic condensation concepts are useful to analyze the sediments distribution patterns in the sedimentary basins, and also to estima te the lateral and vertical variations in rates (VTS) and sedimentation velocities (VVS). Against the most usual in terpretation about the development of the shallowing-upward sequences or parasequences, the maximum rate, velocity, and amount of accommodation values, as well as the highest relative depth, correspond to the lowest le veIs of these sequences, and are decreasing towards the topo Durante las etapas de máxima transgresión pueden ocurrir procesos de condensación en las partes distales de las cuencas, pero también hay procesos de condensación durante las etapas de máxima regresión en las partes más someras de las plataformas. Las secciones condensadas no sólo están asociadas a las superficies de máxima transgresión sino también a los cortejos generados en condiciones de bajo nivel del mar. Los conceptos de condensación estratigráfica, condensación sedimentaria y condensación tafonómica son útiles para analizar las pautas de distribución de los sedimentos en las cuencas, así como para estimar las variaciones laterales y verticales de las tasas (VTS) y de las velocidades de sedimentación (VVS). En contra de la interpretación más usual del desarrollo de las secuencias de somerización o de las parasecuencias, los máximos valores de tasa, velocidad, profundidad relativa y grado de acomodación de los sedimentos de estas secuencias corresponden a los niveles basales, y los valores de estas variables disminuyen hacia el techo. La distinción entre los procesos de condensación de estas tres categorías permite predecir que los grados de condensación sedimentaria y de condensación estratigráfica serán mayores hacia las partes distales de las plataformas; mientras que los procesos de condensación estratigráfica sin condensación sedimentaria presentarán su máxima intensidad y frecuencia en las áreas más someras de las plataformas. Las secciones condensadas pueden servir para evidenciar ciclos eustáticos y para establecer correlaciones temporales. Sin embargo, si se siguen correlacionando indiscriminadamente las secciones condensadas de las zonas medias y distales de las cuencas, generadas durante máximos transgresivos, con las secciones condensadas de las zonas proximales, debidas a máximos regresivos, las correlaciones temporales establecidas serán tan diacrónicas como las facies más progradantes o retrogradan tes desarrolladas en las plataformas. The distinction between processes of each one of the three categories of condensation allows to make the prediction that sedimentary and stratigraphic condensation degrees will be higher towards the distal portions of the platforms, whilst the stratigraphic condensation processes without sedimentary condensation will show the maximum intensity and frequency in the shallowest portions of the platforms. Condensed sections can serve to evidence eustatic cycles and the establishment of temporal correlations. However, if the condensed sections from the middle and distal portions of the basins, generated during maximum transgressions, are correlated with the condensed sections of the proximal zones, due to regressive maximums, the temporal correlations can be as diachronous as the most retrogradational or progradational facies developed in the shelves

The Middle Jurassic eastern margin of the Iberian platform system (eastern Spain). Palaeogeography and biodispersal routes of ammonoids.

From a sedimentological and palaeogeographical point of view, in the eastern margin of the Iberian platform system, Middle Jurassic deposits are represented by a thick pile of carbonates with minor marls interbedded. Different facies, within the Tortosa, Aragonese and Castilian platforms, pertain to two categories: internal platform and external platform facies. A system of extensional faults was the major factor determining the differentiation of several shallow, carbonate, epicontinental platforms. The so-called Iberian Basin was a shallow intracratonic platform system, in which a relatively deep extensional basin (the Catalan Basin) started to be differentiated during the late Bajocian. In the eastern part of this faulted platform system, the occurrence of a listric fault, dipping towards the east, conditioned the development of a late Bajocian differentiated subsident area named the Tortosa Platform. From a palaeobiogeographical point of view, the ammonite fossil assemblages of the Iberian platforms are composed of Sub-Mediterranean taxa. At the eastern margin of the Iberian platform system, the appearance and distribution of shells of ammonoids were taphonomically and ecologically controlled by regional changes of relative sea level. A Sub-Mediterranean zonation can be recognized, although most of the ammonites shells correspond to adult individuals arrived by necroplanktic drift from more open-marine or oceanic areas. The following criteria are relevant in recognizing the maximum deepening episodes in the Iberian platform system: colonization (including ontogenic development) of open-marine taxa, immigration of oceanic taxa and development of endemic species. In terms of Sequence Stratigraphy, the development of expanded, external platform sections in the Tortosa Platform during the Garantiana Biochron (late Bajocian) is noteworthy. During this episode, the Iberian platform system reached the maximum bathymetric values and acted as a biogeographical dispersal area for some taxonomic groups of ammonoids between the Western Tethys and the Proto-Atlantic

Evaluación del efecto de una dieta hipocalórica modificada en pacientes obesos con artropatía crónica sobre el peso: factores de riesgo cardiovascular y marcadores de remodelado óseo

La obesidad se relaciona con la artrosis en el anciano. El objetivo de este estudio fue evaluar el efecto de una dieta hipocalórica sobre el peso, composición corporal y metabolismo óseo pacientes con obesidad y artrosis. Se realizó una intervención con una dieta modificada y educación nutricional en 62 pacientes con IMC>35 kg/m2 pendientes de cirugía ortopédica. Se determinaron al inicio y a los tres meses: antropometría; composición corporal; parámetros de riesgo cardiovascular y de metabolismo óseo; una encuesta nutricional; y calidad de vida. La dieta hipocalórica modificada: Produjo un descenso significativo del peso de entre el 5-10%; consiguió una pérdida de masa grasa; se observó una mejoría en algunos factores de riesgo cardiovascular; se obtuvo un aumento discreto de la 25OHvitamina D, pero existió un aumento de los parámetros metabólicos relacionados con la resorción ósea; y se observó una mejoría de las esferas de dolor y capacidad funcional.Departamento de Medicina, Demartología y Toxicologí

Factores que favorecen el reingreso en intensivos de pacientes con síndrome coronario agudo

Introduction: About 7% of patients admitted in Intensive Care Units (ICUs) due to acute coronary syndrome (ACS) in Spain, are readmitted again later. Objectives: Identify the possible causes and predisposing factors for returning to ICU because of ACS. Methodology: Retrospective, descriptive, comparative and longitudinal study of patients admitted for ACS in the ICU between January 2008 and December 2013.Demographic variables, number of admissions, admission risk factors (dyslipidemia, hypertension and diabetes) and non heart-healthy life habits (sedentary / obesity, smoking, alcoholism) of patients who come back were collected and were compared with control group (not readmitted patients). Pearson’s Chi 2 test and statistical significance were performed. Results: 2.506 patients were admitted by ACS. Readmissions were 140 (5,58%) after 12,93±16,41 months from their first admission. The ICU’s reentering patients stayed4.97± 3.3 days (4.03±1.8 control group) in their first admission. A table is attached with risk factors’ incidence and non heart–healthy life habits of both groups. Smoking and alcoholism habits are related with readmissions (χ²=5.67; p<0.01)Conclusions: The patients who are readmitted stay more days in ICU in their first admission, have less control about risk factors and less quitting index of nocive habits than control group. It seems to exist an adherence therapeutic problem in the sample studied.Introducción: Alrededor del 7% de los pacientes que ingresan en las Unidades de Cuidados Intensivos (UCI) por síndrome coronario agudo (SCA) en España, reingresan de nuevo tiempo después. Objetivos: Identificar posibles causas y factores predisponentes a reingresar en UCI por SCA.Metodología: Estudio retrospectivo, descriptivo, comparativo y longitudinal de pacientes ingresados por SCA en una UCI polivalente entre enero de 2008 y diciembre de 2013. Se recogen variables demográficas, número de ingresos, factores de riesgo al ingreso (dislipemias, hipertensión arterial y diabetes) y hábitos de vida no cardiosaludables (sedentarismo/obesidad, tabaquismo, enolismo) de pacientes que reingresan y se comparan con grupo de control (pacientes que no reingresan). Se realiza test Chi 2 de Pearson y significación estadística.Resultados: Ingresaron 2.506 pacientes por SCA. Reingresaron 140 (5,58%) a los 12,93±16,41 meses después del primer ingreso. Los que reingresan están en UCI 4.97± 3.3 días (4.03±1.8 grupo control) en su primer ingreso. Se adjunta tabla con incidencia de factores de riesgo y hábitos de vida no saludables de ambos grupos. El tabaquismo y enolismo se relacionan con los reingresos (χ²=5.67; p<0.01)Conclusiones: Los pacientes que reingresan, están más días en UCI en su primer ingreso, presentan un menor control de factores de riesgo y menor índice de abandono de hábitos nocivos que el grupo control. El tabaco y el alcohol son factores que favorecen el reingreso. Parece indicar que existe un problema de adherencia terapéutica en la muestra estudiada. &nbsp

Recommendations on seismic actions on bridges

The paper describes the main features of a technical Recommendation first draft on Seismic Actions on Bridges, promoted by the Spanish Ministry of Public Works (MOPT). Although much more research is needed to clarify the seismic behaviour of the vast class of problems present in port structures the current state of the art allows at least a classificaton of subjects and the establishment of minimum requirements to guide the design. Also the use of more refined methods for specially dangerous situations needs some general guidelines that contribute to mantein the design under reasonable safety margins. The Recommendations of the Spanish MOPT are a first try in those directions

Events around the Triassic–Jurassic boundary in northern and eastern Spain: A review

More than 20 successions containing the Triassic–Jurassic (T–J) boundary were studied in five of the major geological units of Spain. The data are from outcrop, cored boreholes, and interpreted well-logs. A consistent −3.4‰ δ13Corg isotope excursion, starting in the Rhaetian and continuing in the Hettangian, was recorded in Asturias. Climate changes in the T–J transition show a warming episode in the early Hettangian. Other climate changes are indicated by an increase in hygrophytic miospores above the T–J boundary; this reflects a more humid episode at the beginning of the Hettangian. The Messejana Dyke in southeastern Iberia is part of the Central Atlantic Magmatic Province (CAMP). CO2 outgassing related to extensive magmatic activity in the CAMP is thought to be one of the possible factors responsible for the end-Triassic mass extinction. No major sea-level changes or unconformities were recorded at the T–J boundary. Only in the Asturias area was there a well-defined shallow carbonate platform during the T–J transition. The other areas of eastern and northern Spain were occupied by coastal playas and sabkhas that developed in arid climatic conditions. The biotic crisis around the T–J boundary is reflected in the palynomorph record. In Asturias, seven species do not persist beyond the late Rhaetian, and only six appeared in the Triassic–Jurassic transition. However, 22 taxa appeared in the early Hettangian
