Castilian loyalty in the War of Succession. Social mobilization and representation of power in a society at war
La lealtad castellana durante la Guerra de Sucesión fue uno de los topoi más reiterados
en la abundante publicística borbónica. Lo que en este texto se analiza es el modo
cómo se generó esa lealtad castellana: por un lado, mediante una creciente coerción ejercida por los diferentes delegados del monarca, especialmente militares y élites locales; y, por otro, a través de una serie de mecanismos de persuasión social - panfletos, periódicos, sermones y toda clase de rituales cívicos- que permitieron incorporar a la causa del nieto
de Luis XIV a una buena parte de la población castellana. La combinación de las diferentes máscaras del poder logró una elevada movilización social en la guerra, además de construir un nuevo orden político que otorgaba al monarca mayor influencia en el conjunto de Castilla.The Castilian loyalty in the Spanish Succession War was one of the more important
topoi in the plentiful Bourbon propaganda. In this article we analysed how was produced
this Castilian loyalty: in the one hand, by an increasing coercion which king's agents
exercised, principally militaries and local elites; and the other hand, by a joint of social persuasion mechanisms -pamphlets, newspapers, sermons and different civic rituals- that allowed to most Castilian population was incorporated to Louis XIV's grandson support. The combination of these power masks obtained a high social mobilization in the war, in addition to build in the Castile Crown a new political order with more authority to the Spanish monarch.Este trabajo se enmarca dentro del proyecto titulado "El primer reformismo borbónico en el espacio mediterráneo:

Problemas de control en procesos de eutrofización
El aumento de los niveles de nitrógeno y fósforo (nutrientes principales para determinadas algas) en grandes masas de agua debido a la acción contaminante del hombre, puede traer consigo una disminución de la calidad del agua (procesos de eutrofización).
En este trabajo estudiamos un m´etodo de control de esta clase de procesos, basado en el uso de biorreactores (tanques en donde se desarrollarán una serie de procesos que reducirán los niveles de nitrógeno y/o fósforo del agua por debajo de unos umbrales máximos). Matemáticamente estos métodos de control se pueden formular como problemas de control óptimo con restricciones sobre el estado en donde las ecuaciones de estado son un tipo de sistema de ecuaciones cuasilineales

Service Orchestration on a Heterogeneous Cloud Federation
During the last years, the cloud computing technology has emerged as a new way to obtain computing resources on demand in a very dynamic fashion and only paying for what you consume. Nowadays, there are several hosting providers which follow this approach, offering resources with different capabilities, prices and SLAs. Therefore, depending on the users' preferences and the application requirements, a resource provider can fit better with them than another one. In this paper, we present an architecture for federating clouds, aggregating resources from different providers, deciding which resources and providers are the best for the users' interests, and coordinating the application deployment in the selected resources giving to the user the impression that a single cloud is used
VIRUP "En busca de los viral"
Este trabajo es la idea llevada a la práctica, de cuatro amigos, compañeros y alumnos del Grado de Publicidad y Relaciones Públicas de la Universidad de Valladolid. Todo comenzó en una asignatura de segundo de carrera, en la que se nos proponía realizar un proyecto relacionado con las nuevas tecnologías. Nosotros no quisimos quedarnos en lo convencional, y fuimos más allá. Así es como nació VIRUP: “En busca de lo viral”.
La organización de eventos es una de las salidas profesionales que más nos ha llamado la atención desde que comenzamos la carrera, es por ello que quisimos crear algo nuevo y diferente, que fuera por y para alumnos.
Durante las tres ediciones, el principal objetivo ha sido ofrecer a nuestros compañeros contenidos de calidad sobre redes sociales, a través de profesionales del sector. En definitiva, poder generar conocimiento e ideas sobre el mundo digital, que en un futuro les fuesen útiles laboralmente.Departamento de Historia Moderna, Contemporánea y de América, Periodismo y Comunicación Audiovisual y PublicidadGrado en Publicidad y Relaciones Pública
Effect of mycoviruses on growth, spore germination and pathogenicity of the fungus Fusarium circinatum
Producción CientíficaAim of the study: To assess the impact on two mycoviruses recently described in F. circinatum mitovirus 1, and 2-2 (FcMV1 and FcMV2-2) on i) mycelial growth, ii) spore germination and iii) relative necrosis.
Material and methods: Fourteen monosporic strains of F. circinatum (one of each pair infected with mycoviruses and the other without them) of the pathogen with and without viruses were selected for the assay. The statistical analysis, were a linear mixed model of analysis of variance considering one between-subjects factor (isolate) and one within-subjects factor with four levels (1=without viruses, 2=only virus FcMV1, 3=only virus FcMV2-2 and 4=both viruses).
Main results: Colony growth rates of F. circinatum isolates were significantly reduced in presence of mycoviruses (p=0.002). The spore germination was also reduced in the F. circinatum isolates containing mycovirus as compared to mycovirus-free isolates (p<0.001). No significant differences in lesion lengths caused by F. circinatum were found in relation to the presence/absence of mycovirus (p<0.61).
Research highlights: Reduction of the percentage of spore germination in the isolates of F. circinatum with mycovirus infections, as compared to free isolates, provides indications of reduction of metabolic activity and plant physiology are discussed. The lack of significant differences found in the length of the lesions caused by F. circinatum with respect to the presence/absence of mycovirus, indicates that further studies with a larger number of variables are required.Ministerio de Economía, Industria y Competitividad (projects AGL2012-39912 and AGL2015- 69370-R)European Cooperation in Science and Technology (COST Action FP1406 PINESTRENGTH)Portuguese Foundation for Science and Technology (grant SFRH/BPD/122928/2016
Effect of mycoviruses on the virulence of Fusarium circinatum and laccase activity
Producción CientíficaLaccase enzymes (benzenediol: oxygen oxidoreductase, EC 1.10.3.2) play a major role in the degradation of phenolic compounds such as lignin. They are common in fungi and have been suggested to participate in host colonization by pathogenic fungi. Putative mycoviruses have recently been isolated from the causal agent of pine pitch canker disease, Fusarium circinatum Nirenberg & O'Donell. In this study, the effects of single and double mycoviral infections on laccase activity, growth rate and pathogenicity were investigated in fourteen F. circinatum strains. Extracellular laccase activity was analyzed by the Bavendamm test, image processing and a spectrophotometric method. Mycelial growth, in vivo pathogenicity and seedling survival probability were also determined in Monterrey pine (Pinus radiata D. Don) seedlings. The findings showed that (i) mycelial growth of isolates from the same fungal population was homogeneous, (ii) the presence of mycovirus appears to increase the virulence of fungal isolates, (iii) co-infection (with two mycoviruses) caused cryptic effects in fungal isolates, and (iv) laccases embody a possible auxiliary tool in fungal infection. The prospects for biocontrol, the adaptive role of F. circinatum mycoviruses and the importance of laccase enzymes in host colonization are discussed.Ministerio de Economía, Industria y Competitividad (Project AGL2012-39912
Rescaled bootstrap confidence intervals for the population variance in the presence of outliers or spikes in the distribution of a variable of interest
Confidence intervals for the population variance in the presence of outliers or spikes in the distribution of a variable of interest are topics that have not been investigated in depth previously. Results derived from a first Monte Carlo simulation study reveal the limitations of the customary confidence interval for the population variance when the underlying assumptions are violated, and the use of alternative confidence intervals is thus justified. We suggest confidence intervals based on the rescaled bootstrap method for many reasons. First, this is a simple technique that can be easily applied in practice. Second, it is free of probabilistic distributions. Finally, it can be easily applied to the cases of finite populations and samples
selected from complex sampling designs. Results derived from a second Monte Carlo simulation study indicate that the suggested confidence intervals have desirable coverage rates with smaller average widths.
Accordingly, an advantage of the suggested confidence intervals is that they offer a good compromise between simplicity and desirable properties. The various simulation studies are based on different scenarios that may arise in practice, such as the presence of outliers or spikes, and the fact that the underlying assumptions of the customary confidence interval are violated
