Agua y desarrollo urbano en la Castilla medieval: aportaciones a su estudio en la ciudad de Guadalajara

Uno de los elementos críticos del urbanismo castellano en la Edad Media era el acceso a recursos hídricos que pudieran servir para el abastecimiento humano. En función del clima, la orografía, y las infraestructuras heredadas de épocas anteriores, cada ciudad y villa del reino trató de buscar la mejor manera de asegurar el suministro de agua para sus vecinos. A lo largo de este trabajo se analiza la forma en la que el concejo de Guadalajara, así como los principales poderes religiosos y nobiliarios de la ciudad, fueron trazando la red de abastecimiento urbano durante la Baja Edad Media, a partir de las fuentes del paraje conocido como El Sotillo, y cómo realizaron la explotación económica del cauce del río Henares en las cercanías del municipio. El agua, bien escaso en la Alcarria, fue durante los siglos bajomedievales un elemento de gran importancia económica y símbolo de prestigio social, que despertó el interés de todos los grupos de la sociedad arriacense.

Frequency of mutations and polymorphisms in borderline ovarian tumors of known cancer genes.

Borderline ovarian tumors represent an understudied subset of ovarian tumors. Most studies investigating aberrations in borderline tumors have focused on KRAS/BRAF mutations. In this study, we conducted an extensive analysis of mutations and single-nucleotide polymorphisms (SNPs) in borderline ovarian tumors. Using the Sequenom MassArray platform, we investigated 160 mutations/polymorphisms in 33 genes involved in cell signaling, apoptosis, angiogenesis, cell cycle regulation and cellular senescence. Of 52 tumors analyzed, 33 were serous, 18 mucinous and 1 endometrioid. KRAS c.35G>A p.Gly12Asp mutations were detected in eight tumors (six serous and two mucinous), BRAF V600E mutations in two serous tumors, and PIK3CA H1047Y and PIK3CA E542K mutations in a serous and an endometrioid BOT, respectively. CTNNB1 mutation was detected in a serous tumor. Potentially functional polymorphisms were found in vascular endothelial growth factor (VEGF), ABCB1, FGFR2 and PHLPP2. VEGF polymorphisms were the most common and detected at four loci. PHLPP2 polymorphisms were more frequent in mucinous as compared with serous tumors (P=0.04), with allelic imbalance in one case. This study represents the largest and most comprehensive analysis of mutations and functional SNPs in borderline ovarian tumors to date. At least 25% of borderline ovarian tumors harbor somatic mutations associated with potential response to targeted therapeutics.

The state and known impacts of fish species transferred to or within continental Africa

Fish introductions have been made from small fish ponds to the largest lakes in Africa. The primary intent of these introductions has been to sustain or increase fish production, although some introductions have been made to develop sport fisheries and to control unwanted organisms. Some of these introductions have fulfilled their objective in the short term, but several of these "successful" introductions have created uncertainties about their long term sustainability. Lates niloticus, Oreochromis niloticus, O. leucostictus, Tilapia melanopleura and T. zilli were introduced into lakes Victoria and Kyoga in 1950s and early 1960s. By the 1980s O. niloticus and O. niloticus dominated the fisheries of these lakes, virtually eliminating a number of endemic fish species. The loss of genetic diversity of the fish in the worlds second largest lake has also been accompanied by a loss of trophic diversity. The transformation of the fish community has, in Lake Victoria coincided with a profound eutrophication (algal blooms, fish kills, hypolimnetic anoxia) which might be related to alterations of the lake's food-web structure. In contrast, the introduction of a planktivore, Limnothrissa miodon into Lake Kivu and the Kariba reservoir has established highly successful fisheries with little documented effect on the pre-existing fish community or trophic ecology of the lakes. The highly endemised species-rich African Great lakes may be particularly sensitive to species introductions and require special consideration and caution when introductions are contemplated because species extinctions, introgressive hybridization and ecosystem alterations may occur following fish introductions.

Non-acute Transient Reversible Adrenal Insufficiency in a Survivor of Critical Illness: A Lesser-known Cause of Primary Adrenal Insufficiency

Objectives: Primary adrenal insufficiency AI is regarded as a progressive disease needing lifelong replacement therapy, but this may not always be the case. Material and methods: A non-acute presentation of AI following a hypotensive episode caused by blood loss was investigated. Results: Adrenal function fully recovered without treatment. Conclusions: There should be a high index of suspicion and a low threshold for performing tests of adrenal function in survivors of critical illness and severe hypotensive episodes.

A Less Known Stroke Mimic: Posterior Reversible Encephalopathy Syndrome

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuro-radiological diagnosis, which can complicate a wide range of conditions. Clinical features include generalised and/or focal neurological deficits. These features are also present in neurovascular disorders, such as stroke. Currently, emphasis in the management of hyperacute stroke is thrombolysis, and it is important to bear in mind stroke mimics as a possible cause of clinical features. The Authors present the case of a 66-year-old man, who presented with acute focal neurological deficit. His brain imaging and history were consistent with PRES.

Performance of Sirex noctilio’s biocontrol agent Deladenus siricidicola, in known and predicted hosts

Survival of the free-living mycetophagous form of Deladenus siricidicola, the major biological control agent of Sirex woodwasp, Sirex noctilio, was tested in known (Pinus taeda) and predicted novel (P. elliottii subsp. elliottii × P. caribaea var. hondurensis) hybrid host taxa. Trials were established in the field to simulate nematode dispersal both naturally by infected wasps and following commercial inoculation, as well as in the laboratory under controlled conditions. Nematodes showed reduced survival in hybrid pine compared with P. taeda for all tree-associated treatments, but performed equivalently in petri-dish bioassays containing substrate of each taxon. Growth of Amylostereum areolatum, the food source of D. siricidicola was lower on plates containing ground hybrid substrate than on plates containing ground P. taeda. Some physical differences were found between taxa, including differences in bordered pit diameters, tracheid widths, and basic density, but these did not consistently explain reduced performance. More plant secondary compounds (predominantly oleoresins) were present in hybrid taxa than in P. taeda, and in standing trees compared with felled trees. Our results suggested that D. siricidicola may not be as effective in hybrid pine taxa for the biological control of S. noctilio as it is in its current known host taxa, possibly because of reduced growth of its food source, A. areolatum in hybrid pine.

Ciclo de los negocios en Colombia: el papel de la política de estabilización

Este documento mide la sincronización entre las políticas de estabilización y el ciclo de los negocios en Colombia en el periodo comprendido entre marzo de 1990 y junio de 2013. Para la construcción de los ciclos se utiliza la metodología clásica y se construye un ciclo de referencia a partir de ciclos individuales de tres índices de actividad económica real. Con el fin de medir la sincronización entre el ciclo de nego­cios y los ciclos de las políticas fiscal y monetaria se utiliza el estadístico de Harding y Pagan (2006). Se concluye que durante el periodo de estudio las políticas de estabilización tienden a ser procíclicas (por el lado fiscal) y acíclicas (por el lado monetario). En la literatura se conoce a este fenómeno como when it rains, it pours y es común que se presente en economías emergentes como la colombiana

UV-A radiation effects on higher plants: exploring the known unknown

Ultraviolet-A radiation (UV-A: 315–400 nm) is a component of solar radiation that exerts a wide range of physiological responses in plants. Currently, field attenuation experiments are the most reliable source of information on the effects of UV-A. Common plant responses to UV-A include both inhibitory and stimulatory effects on biomass accumulation and morphology. UV-A effects on biomass accumulation can differ from those on root: shoot ratio, and distinct responses are described for different leaf tissues. Inhibitory and enhancing effects of UV-A on photosynthesis are also analysed, as well as activation of photoprotective responses, including UV-absorbing pigments. UV-A-induced leaf flavonoids are highly compound-specific and species-dependent. Many of the effects on growth and development exerted by UV-A are distinct to those triggered by UV-B and vary considerably in terms of the direction the response takes. Such differences may reflect diverse UV-perception mechanisms with multiple photoreceptors operating in the UV-A range and/or variations in the experimental approaches used. This review highlights a role that various photoreceptors (UVR8, phototropins, phytochromes and cryptochromes) may play in plant responses to UV-A when dose, wavelength and other conditions are taken into account.

Gobierno, corte y ciudad en Nápoles: el fin del Parlamento y la crisis del gobierno virreinal (1637-1647)

En esta Tesis Doctoral se aborda el análisis de la Nápoles virreinal entre 1637 y 1647 con una investigación en tres planos: gobierno, corte y ciudad. Esto se realiza a través del estudio del gobierno de Nápoles, con especial atención al Parlamento General del Reino, que se convocó por última vez en 1642. Con la óptica privilegiada que brinda esta institución entre la administración virreinal y urbana, es posible comprender los intereses locales, la agenda napolitana en las dinámicas globales de la Monarquía, los intereses de linaje o “públicos” de los virreyes y, en definitiva, se pone de manifiesto una nueva mirada que parte de la propia realidad napolitana para comprender la estructura de gobierno, a través de fuentes inéditas y labor de archivo, en un periodo convulso para la Monarquía de España. Con todo, se insertan las instituciones en las dinámicas políticas y ceremoniales de la ciudad y Reino de Nápoles. Asimismo, todo ello se estudia a través del canal de la corte de Madrid, ya que los virreyes eran nombrados por el rey y lo representaban en el Reino. Por tanto, las decisiones de gobierno se veían afectadas por las circunstancias cortesanas. En concreto, este periodo coincide con los años de la privanza del conde-duque y el posterior ascenso de Luis de Haro. Así, los virreyes duque de Medina de las Torres, Almirante de Castilla y duque de Arcos se incardinan no solo en la política napolitana, sino en la de la Monarquía de Felipe IV. Por último, la ciudad es actor principal de esta investigación, en su configuración física y simbólica, ya que la capital tuvo una significación singular en el caso napolitano por la sociografía de sus élites y su implicación en el gobierno municipal.

Conditional entropy and predictability for non-reversible Markov systems

The purpose of this thesis is to clarify the role of non-equilibrium stationary currents of Markov processes in the context of the predictability of future states of the system. Once the connection between the predictability and the conditional entropy is established, we provide a comprehensive approach to the definition of a multi-particle Markov system. In particular, starting from the well-known theory of random walk on network, we derive the non-linear master equation for an interacting multi-particle system under the one-step process hypothesis, highlighting the limits of its tractability and the prop- erties of its stationary solution. Lastly, in order to study the impact of the NESS on the predictability at short times, we analyze the conditional entropy by modulating the intensity of the stationary currents, both for a single-particle and a multi-particle Markov system. The results obtained analytically are numerically tested on a 5-node cycle network and put in correspondence with the stationary entropy production. Furthermore, because of the low dimensionality of the single-particle system, an analysis of its spectral properties as a function of the modulated stationary currents is performed.

Innovative layout design and radiated harmonic analysis for advanced frequency-diverse array solutions

Wireless power transfer is becoming a crucial and demanding task in the IoT world. Despite the already known solutions exploiting a near-field powering approach, far-field WPT is definitely more challenging, and commercial applications are not available yet. This thesis proposes the recent frequency-diverse array technology as a potential candidate for realizing smart and reconfigurable far-field WPT solutions. In the first section of this work, an analysis on some FDA systems is performed, identifying the planar array with circular geometry as the most promising layout in terms of radiation properties. Then, a novel energy aware solution to handle the critical time variability of the FDA beam pattern is proposed. It consists on a time-control strategy through a triangular pulse, and it allows to achieve ad-hoc and real time WPT. Moreover, an essential frequency domain analysis of the radiating behaviour of a pulsed FDA system is presented. This study highlights the benefits of exploiting the intrinsic pulse harmonics for powering purposes, thus minimising the power loss. Later, the electromagnetic design of a radial FDA architecture is addressed. In this context, an exhaustive investigation on miniaturization techniques is carried out; the use of multiple shorting pins together with a meandered feeding network has been selected as a powerful solution to halve the original prototype dimension. Finally, accurate simulations of the designed radial FDA system are performed, and the obtained results are given.
