Análisis del tratamiento informativo de los escándalos del rey emérito, Juan Carlos I, en la prensa española de referencia

En el siguiente trabajo de investigación se analiza el tratamiento informativo de los escándalos del rey emérito, Juan Carlos I, en la prensa española de referencia, en lo referente al enfoque otorgado por los medios de cara a la opinión pública. Tras analizar las noticias publicadas por el diario ABC y eldiario.es se ha podido determinar que el enfoque tras el conocimiento de los supuestos delitos de Don Juan Carlos estuvo, principalmente, sobre el conflicto político que desataron los supuestos delitos que habría cometido el emérito, así como la responsabilidad de éste en esos delitos y de los propios políticos que aprovecharon la situación para seguir con los reproches mutuos utilizando el escándalo del Juan Carlos IThe following research paper analyzes the informative treatment of the scandals of King Emeritus, Juan Carlos I, in the leading Spanish press, in relation to the approach given by the media towards public opinion. After analyzing the news published by the newspaper ABC and eldiario.es, it has been possible to determine that the focus behind the knowledge of the alleged crimes of Don Juan Carlos was, mainly, on the political conflict that unleashed the alleged crimes that the emeritus would have committed, as well as the responsibility of the latter in those crimes and of the politicians themselves who took advantage of the situation to continue with mutual reproaches using the Juan Carlos I scandal.Departamento de Historia Moderna, Contemporánea y de América, Periodismo y Comunicación Audiovisual y PublicidadGrado en Periodism

Implementation of Irrigation with Dairy Cattle Manure for Tropical Perennial Pastures in Costa Rica

Animal manures allow nutrients recycling in cropping systems, while contributing to the fulfillment of environmental standards. Pasture irrigation with animal manures has been fostered for Costa Rican dairy farms over the last 15 yr. A lack of information and training regarding irrigation and management of animal manures has led to the implementation of diverse methods by producers, but those have not yet been characterized. This study aimed to describe the current management of Costa Rican dairy farms irrigating perennial pastures with slurries. The farms were mostly grass-based systems with supplements fed to cows during the time spent at the milking parlor and/or in feeding stalls through the day. Farms collect manure when facilities are washed with water, which is then stored in plastic tanks or cement structures for less than 1 day before irrigating pastures. The amount of water used by dairy producers was greater than the recommended water/manure ratio (13.4 vs. 4.0 L kg–1), with only one farm reporting values below this ratio. Slurries were sampled and analyzed for their nutrient and microbial content. Both nutrient and microbial content varied in this study due to factors specific to each farm, especially with respect to water management. The variability found in water use among farms and regions (2.4–36.7 L kg–1) may generate unintended consequences from an environmental standpoint. Sustainability of Costa Rican dairy farms can be enhanced if specific guidelines for manure irrigation are developed, which could have benefits for chemical fertilizer use and environmental effect.Universidad de Costa Rica/[739-B7-063]/UCR/Costa RicaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Agroalimentarias::Centro de Investigación en Nutrición Animal (CINA)UCR::Vicerrectoría de Docencia::Ciencias Agroalimentarias::Facultad de Ciencias Agroalimentarias::Escuela de Zootecni

A hybrid ARIMA and artificial neural networks model to forecast particulate matter in urban areas: The case of Temuco, Chile

Air quality time series consists of complex linear and non-linear patterns and are difficult to forecast. Box-Jenkins Time Series (ARIMA) and multilinear regression (MLR) models have been applied to air quality forecasting in urban areas, but they have limited accuracy owing to their inability to predict extreme events. Artificial neural networks (ANN) can recognize non-linear patterns that include extremes. A novel hybrid model combining ARIMA and ANN to improve forecast accuracy for an area with limited air quality and meteorological data was applied to Temuco, Chile, where residential wood burning is a major pollution source during cold winters, using surface meteorological and PM10 measurements. Experimental results indicated that the hybrid model can be an effective tool to improve the PM10 forecasting accuracy obtained by either of the models used separately, and compared with a deterministic MLR. The hybrid model was able to capture 100% and 80% of alert and pre-emergency episodes, respectively. This approach demonstrates the potential to be applied to air quality forecasting in other cities and countries

The prince and the pauper. A tale of anticancer targeted agents

Cancer rates are set to increase at an alarming rate, from 10 million new cases globally in 2000 to 15 million in 2020. Regarding the pharmacological treatment of cancer, we currently are in the interphase of two treatment eras. The so-called pregenomic therapy which names the traditional cancer drugs, mainly cytotoxic drug types, and post-genomic era-type drugs referring to rationally-based designed. Although there are successful examples of this newer drug discovery approach, most target-specific agents only provide small gains in symptom control and/or survival, whereas others have consistently failed in the clinical testing. There is however, a characteristic shared by these agents: -their high cost-. This is expected as drug discovery and development is generally carried out within the commercial rather than the academic realm. Given the extraordinarily high therapeutic drug discovery-associated costs and risks, it is highly unlikely that any single public-sector research group will see a novel chemical "probe" become a "drug". An alternative drug development strategy is the exploitation of established drugs that have already been approved for treatment of non-cancerous diseases and whose cancer target has already been discovered. This strategy is also denominated drug repositioning, drug repurposing, or indication switch. Although traditionally development of these drugs was unlikely to be pursued by Big Pharma due to their limited commercial value, biopharmaceutical companies attempting to increase productivity at present are pursuing drug repositioning. More and more companies are scanning the existing pharmacopoeia for repositioning candidates, and the number of repositioning success stories is increasing. Here we provide noteworthy examples of known drugs whose potential anticancer activities have been highlighted, to encourage further research on these known drugs as a means to foster their translation into clinical trials utilizing the more limited public-sector resources. If these drug types eventually result in being effective, it follows that they could be much more affordable for patients with cancer; therefore, their contribution in terms of reducing cancer mortality at the global level would be greater

Mediastinal paraganglioma detected by 111in-Pentetreotide scintigraphy and SPECT/TC. A case report

Introduction: Mediastinal paragangliomas are low incidence tumors that arise from neural crest. Its diferential diagnosis include several malignant diseases, so its correct characterization is mandatory for an adecuate therapeutic management. 111In-Pentetreotide scintigraphy/SPECT-CT can detect paraganglioma, mainly in those cases of atypical or unsuspected location, and may have a significant role in follow-up of those patients diagnosed with multifocal and familiar paraganglioma. Case: Here we report a case of an extremely rare middle mediastinal paraganglioma, detected by scintigraphy and SPECT-CT with 111In-Pentetreotide in a patient diagnosed of multifocal and family history of paraganglioma. Surgery was carried out by median sternotomy and extracorporeal circulation. The pathological examination of the surgical specimen showed a para-aortic low-grade tumor, positive for chromogranin and synaptophysin, cytokeratin AE1-AE3 negative and Ki67 lower than 5%, compatible with paraganglioma. Currently, the patient is tumor free, under clinical monitoring. Conclusions: 111In- Pentetreotide scan proved to be a helpful diagnostic method because of its potential to explore full body, so It allows us to locate unsuspected and atypical location paragangliomas. This finding suggests that patients diagnosed with multifocal head and neck paraganglioma should undergo periodical follow-up with 111In-Pentetreotide scan to detect unsuspected paraganglioma.Introducción: Los paragangliomas mediastínicos son tumores de baja incidencia que surgen de la cresta neural. Su diagnóstico diferencial incluye varias enfermedades malignas, por lo que su correcta caracterización es obligatoria para un adecuado tratamiento. La gammagrafía SPECT-CT con 111In-pentetreótida puede detectar paragangliomas, principalmente en aquellos casos de localización atípica o no sospechada, y puede tener un papel significativo en el seguimiento de los pacientes diagnosticados con paraganglioma multifocal y familiar. Caso clínico: Se presenta un caso de un paraganglioma mediastínico medio extremadamente raro, detectado por gammagrafía y SPECT-CT con 111In-pentetreótida en un paciente diagnosticado de historia multifocal y familiar de paraganglioma. La cirugía se realizó mediante esternotomía media y circulación extracorpórea. El examen patológico de la muestra quirúrgica mostró un tumor paraórtico de bajo grado, positivo para cromogranina y sinaptofisina, citoqueratina AE1-AE3 negativo y Ki67 menor de 5%, compatible con paraganglioma. Actualmente, el paciente está libre de tumores, bajo supervisión clínica. Conclusiones: La exploración con 111In-pentetreótida demostró ser un método de diagnóstico útil debido a su potencial para explorar todo el cuerpo, por lo que permite localizar paragangliomas insospechados y de localización atípica. Este hallazgo sugiere que los pacientes diagnosticados con paraganglioma multifocal de cabeza y cuello deben someterse a un seguimiento periódico con 111In-pentetreótida para detectar paraganglioma no sospechado

Contrasting catastrophic eruptions predicted by different intrusion and collapse scenarios

Catastrophic volcanic eruptions triggered by landslide collapses can jet upwards or blast sideways. Magma intrusion is related to both landslide-triggered eruptive scenarios (lateral or vertical), but it is not clear how such different responses are produced, nor if any precursor can be used for forecasting them. We approach this problem with physical analogue modelling enhanced with X-ray Multiple Detector Computed Tomography scanning, used to track evolution of internal intrusion, and its related faulting and surface deformation. We find that intrusions produce three different volcano deformation patterns, one of them involving asymmetric intrusion and deformation, with the early development of a listric slump fault producing pronounced slippage of one sector. This previously undescribed early deep potential slip surface provides a unified explanation for the two different eruptive scenarios (lateral vs. vertical). Lateral blast only occurs in flank collapse when the intrusion has risen into the sliding block. Otherwise, vertical rather than lateral expansion of magma is promoted by summit dilatation and flank buttressing. The distinctive surface deformation evolution detected opens the possibility to forecast the possible eruptive scenarios: laterally directed blast should only be expected when surface deformation begins to develop oblique to the first major fault

Regeneration dynamics in fragmented landscapes at the leading edge of distribution: Quercus suber woodlands as a study case

[EN] Aims We studied the regeneration dynamics of woodlands and abandoned old fields in a landscape dominated by Quercus suber in its lower limits of rainfall and temperature. Two hypotheses were established: (1) regeneration of Quercus species is strongly favored by the presence of tree cover; and (2) growth of Q. suber is driven by the climatic variables that represent the lower ecological limit of its leading distribution edge. Methods We selected woodlands and old fields with and without tree remnants (n = 3 per type), and analyzed stand structure, soil parameters and tree growth. Results Succession was arrested in old fields without tree remnants. By contrast, remnant trees were accelerators of forest recovery in old fields. Tree cover played a fundamental role in Quercus recruitment throughout seed dispersal and facilitation that mitigate the effects of summer drought on seedlings. Also, tree cover improved soil parameters (e.g., organic matter) that are important factors for understanding differences in regeneration. Winter/spring precipitation exerted a positive effect on tree growth, as well as temperatures during winter/spring and September. Conclusions Regeneration dynamics are modeled by the density of tree cover in the cold and dry edge of the distribution area of Q. suber where Q. ilex is increasing in abundance. Although temperature has a positive effect on the tree growth of Q. suber, when demographic processes are considered, decreases in water availability likely play a critical role in Q. ilex recruitment. This in turn changes dominance hierarchies, especially in abandoned areas with little or no tree cover.This study was funded by project SA013G19 from “Junta de Castilla y León” and by research grants awarded for final projects directed in the Master’s degree in Biology and Conservation of Biodiversity at the University of Salamanca, Spain.Publicación en abierto financiada por el Consorcio de Bibliotecas Universitarias de Castilla y León (BUCLE), con cargo al Programa Operativo 2014ES16RFOP009 FEDER 2014-2020 DE CASTILLA Y LEÓN, Actuación:20007-CL - Apoyo Consorcio BUCL
