Usando la Web 2.0 en la distribución de puestos de prácticas en Enfermería: proyecto piloto

Las prácticas clínicas de Enfermería, son un elemento fundamental para el proceso de enseñanza – aprendizaje de los estudiantes de Grado en Enfermería. En estos entornos, los estudiantes toman contacto con su futura profesión aplicando los conocimientos teóricos y desarrollando habilidades para la prestación de cuidados a los pacientes. En este trabajo de investigación acción, se describen y aportan resultados de las dos etapas determinadas en este estudio piloto. En primer lugar, se estudia y analiza la opinión de una muestra accidental de estudiantes del grado en Enfermería sobre la organización y distribución de puestos de prácticas en este momento, empleando como instrumento un cuestionario de 15 ítems. Posteriormente y tras el análisis de los datos obtenidos en la fase previa, se decide diseñar y aplicar un instrumento basado en la Web 2.0 y se formula un protocolo en el que la elección de las unidades de prácticas las realiza la estudiante o el estudiante, siguiendo los pasos establecidos

Free Form of the Foldy-Wouthuysen Transformation in External Electromagnetic Fields

We derive the exact Foldy-Wouthuysen transformation for Dirac fermions in a time independent external electromagnetic field in the basis of the Ritus eigenfunctions, namely the eigenfunctions of the operator $(\gamma \cdot \Pi)^2$, with $\Pi^\mu = p^\mu - e A^\mu$. In this basis, the transformation acquires a free form involving the dynamical quantum numbers induced by the field.Comment: 8 pages. Accepted in J. Phys. A: Math. and Theo.

Identification and observation in the anode line of PEM fuel cell stacks

In this work, some potential identification/observation problems that arise in the anode line of a typical Polymer Electrolyte Membrane (PEM) fuel cell based system are highlighted and then solved. They involve estimating the hydrogen input flow at the stack anode and the water transport across the membrane. It is argued that estimating the membrane water transport is of special interest since it gives relevant information on the actual performance and state of the fuel cell. Both problems are solved by constructing robust observers and parameter identification algorithms based on the Generalized Super-Twisting Algorithm.Peer ReviewedPostprint (author’s final draft

Features associated to woody hosts in the bacterial pathogen of olive plants Pseudomonas savastanoi pv. savastanoi

The causal agent of olive knot disease, Pseudomonas savastanoi pv. savastanoi, belongs to the Pseudomonas syringae complex, a bacterial group causing diseases in a broad variety of both woody and herbaceous plant species. Here we summarize our results regarding a set of P. savastanoi pv. savastanoi features exclusively found in the genomes of bacteria from the P. syringae complex isolated from woody hosts. Comparative genomics and evolutionary studies allowed us to identify a 15 kb genomic island (WHOP, from woody host and Pseudomonas), carrying a set of genes involved in degradation of phenolic compounds and exclusively found in bacterial pathogens of woody hosts. Deletion of several WHOP-encoded genes in Pseudomonas savastanoi pv. savastanoi NCPPB 3335 revealed that they play a role in the virulence of the strain in woody olive plants but not in in vitro-grown (nonwoody) plants. In addition, several type III secretion system effectors belonging to the HopAF, HopAO and HopBL families were shown to be clustered across the P. syringae complex according to the woody/herbaceous nature of their host of isolation. Further functional analyses of these virulence factors are needed to facilitate the design of novel strategies directed to control bacterial pathogens of woody hosts.Universidad de Málaga.

Comparative Analysis of the Type III Secretion System Effector Repertoires of Pseudomonas savastanoi Pathovars Pathogenic on Woody Hosts

Comunicación de tipo pósterThe species Pseudomonas savastanoi, a member of the Pseudomonas syringae complex, includes four pathovars causing knots or excrescences in woody hosts: P. savastanoi pv. savastanoi (Psv), pv. fraxini (Psf), pv. nerii (Psn) and pv. retacarpa (Psr), comprising isolates from olive, ash, oleander and broom plants, respectively. Pathogenicity of P. savastanoi is dependent, among other factors, on the type III secretion system (T3SS) and its effector (T3E) repertoire. Furthermore, a putative role in the interaction with woody hosts has been suggested for several of these T3E. The recent availability of the genome sequences of several P. savastanoi strains isolated from different hosts has facilitated bioinformatics predictions of their T3SS genes and T3E pools, the study of their distribution in other strains of the P. syringae complex isolated from woody hosts and the functional analysis of several of these secreted proteins. As previously reported for Psv, Psn and Psf, here we show that pathogenicity of Psr ICMP16945, is also dependent on the T3SS. Psv strains NCPPB 3335, ICMP4352 and PseNe107 share a core set of at least 22 T3E, 18 of which are also encoded in Psn ICMP16943, Psf ICMP7711 and Psr ICMP16945. However, these three strains encode truncated versions of 1-2 of these 18 T3E and, Psr ICMP16945 contains three pathovarspecific T3E. Our results also show that several T3E, including HopAO1, are phylogenetically clustered across the P. syringae complex according to the woody/herbaceous nature of their host of isolation, suggesting host specialization of these effectors in this complex.Universidad de Málaga.

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair

Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility, as it participates in different DNA repair and damage tolerance pathways in which gap-filling DNA synthesis is required. In this work we show that human Polλ is conjugated with Small Ubiquitin-like MOdifier (SUMO) proteins both in vitro and in vivo, with Lys27 being the main target of this covalent modification. Polλ SUMOylation takes place in the nuclear pore complex and is mediated by the E3 ligase RanBP2. This post-translational modification promotes Polλ entry into the nucleus, which is required for its recruitment to DNA lesions and stimulated by DNA damage induction. Our work represents an advance in the knowledge of molecular pathways that regulate cellular localization of human Polλ, which are essential to be able to perform its functions during repair of nuclear DNA, and that might constitute an important point for the modulation of its activity in human cells

The Image of Women Architects in Films, 1912–1943: New Careers and Stereotyped Femininities

Contrary to what might be expected, portrayals of women architects in films can be found as far back as the early decades of the twentieth century. In this article, the authors review a few films released between 1912 and 1943 in which one of the characters is a woman architect, focusing on three of them: Dr. Monica (1934), Woman Chases Man (1937) and The Lamp Still Burns (1943). The article explores the ways in which architecture was used by screenwriters and directors as a suitable vehicle to portray the ‘new woman’, as well as the conflicts that arise when a woman practices a traditionally male profession. It analyses the differences and limitations of these depictions, and the stereotypes regarding femininity that permeated these works of fiction

Maximizing the hyperpolarizability of one-dimensional systems

Previous studies have used numerical methods to optimize the hyperpolarizability of a one-dimensional quantum system. These studies were used to suggest properties of one-dimensional organic molecules, such as the degree of modulation of conjugation, that could potentially be adjusted to improve the nonlinear-optical response. However, there were no conditions set on the optimized potential energy function to ensure that the resulting energies were consistent with what is observed in real molecules. Furthermore, the system was placed into a one-dimensional box with infinite walls, forcing the wavefunctions to vanish at the ends of the molecule. In the present work, the walls are separated by a distance much larger than the molecule's length; and, the variations of the potential energy function are restricted to levels that are more typical of a real molecule. In addition to being a more physically-reasonable model, our present approach better approximates the bound states and approximates the continuum states - which are usually ignored. We find that the same universal properties continue to be important for optimizing the nonlinear-optical response, though the details of the wavefunctions differ from previous result.Comment: 10 pages, 5 figure

Practical application of the Mercer and Beck models in the nursing specialties

El vínculo afectivo es la atracción que un individuo siente por otro. La conducta de apego busca la unión emocional y seguridad del bebé hacia su madre. Distintas especialidades de enfermería indican la importancia de trabajar el vínculo afectivo, las relaciones familiares y utilizar el proceso enfermero partiendo de modelos conceptuales. Los modelos conceptuales de Mercer y Beck estudian factores a considerar en la formación y desarrollo de vínculos afectivos entre madres e hijos. Este estudio pretende desarrollar conocimientos, habilidades y actitudes que permitan una atención óptima al bebé y su familia. Analizando los elementos comunes y diferenciadores de ambos modelos y justificando la necesidad de prestar especial atención a la formación y mantenimiento del vínculo maternofilial desde la perspectiva de las diferentes especialidades de enfermería, se utiliza el proceso enfermero para la detección y resolución de problemas que afecten al vínculo afectivo y a las relaciones familiares.Bonding is the attraction one person feels for another.
