Gestión de proyectos: antecedentes y consecuentes en el contexto del proyecto y de la organización
2020
En los entornos actuales, caracterizados por altos niveles de competitividad e incertidumbre, las organizaciones se han enfocado en desarrollar sus actividades a través de proyectos, orientados al logro de los objetivos estratégicos. La gestión de proyectos [Project Management (PM)], se refiere a la aplicación de conocimientos, habilidades, herramientas, técnicas, métodos y competencias, a las actividades de los proyectos, con el objetivo alcanzar el éxito en el desempeño de los mismos. En este sentido, la PM, ha adquirido una alta relevancia, por el impacto que genera en la competitividad de las empresas y en el desarrollo económico de los países. A nivel científico, se han logrado avances…
Análisis del museo como narración audiovisual
2011
Resumen tomado de la publicación Título, resumen y palabras clave también en inglés Monográfico con el título: "Arte, Maestros y Museos" El museo se adapta a los tiempos, haciendo propios los recursos audiovisuales con propuestas discursivas para la interacción y el aprendizaje. Este artículo expone algunas líneas de investigación centradas en el museo como narración audiovisual desde la Teoría de la Comunicación y el Análisis Fílmico, entre otras perspectivas, aportando el ejemplo del Museo CajaGRANADA Memoria de Andalucía.

Cytoglobin (Cygb) is a vertebrate globin with so far poorly defined function. It is expressed in the fibroblast cell-lineage but has also been found in neurons. Here we provide, using immunohistochemistry, a detailed study on the distribution of Cygb in the mouse brain. While Cygb is a cytoplasmic protein in active cells of the supportive tissue, in neurons it is located in the cytoplasm and the nucleus. We found the expression of Cygb in all brain regions, although only a fraction of the neurons was Cygb-positive. Signals were of different intensity ranging from faint to very intense. Telencephalic neurons in all laminae of the cerebral cortex, in the olfactory bulb (in particular periglom…
Unusual basement layer in the midgut of gammaridean Niphargus virei Chevreux (Crustacea, Amphipoda).
1988
The basement membrane of the midgut and posterior caeca epithelium in the gammaridean amphipod Niphargus virei Chevreux, 1896 is made of an unusual structure. This basal lamina, properly called “basal layer”, shows a dense sheet formed by a system of dense hexagonal plates connected by thin filaments. Histochemical studies and enzymatic reactions lead to the conclusion that these structures are proteinaceous, without collagenous protein, and embedded in a neutral polysaccharide matrix. The possible mechanical significance of these mesenteric structures is discussed.
Comparative experimental analysis on the compressive behaviour of masonry columns strengthened by FRP, BFRCM or steel wires
2017
Abstract In the last decade, several studies have investigated the application of Fibre Reinforced Polymer (FRP) wraps to masonry piers in order to provide a confinement effect and enhance compressive strength and ductility. Although this technique has proved to be quite effective, various drawbacks arise when organic resins are used to bind fibres. To solve these problems, different techniques have been developed to be used as alternative methods for enhancing the structural performances of weak masonry columns. Among these, the use of Basalt Fibre Reinforced Cementitious Matrix (BFRCM) wrapping, or the application of steel wires at mortar joints. This paper presents the results of an expe…
MICROLENSING OF QUASAR ULTRAVIOLET IRON EMISSION
2013
We measure the differential microlensing of the UV Fe II and Fe III emission line blends between 14 quasar image pairs in 13 gravitational lenses. We find that the UV iron emission is strongly microlensed in four cases with amplitudes comparable to that of the continuum. Statistically modeling the magnifications, we infer a typical size of r{sub s}∼4√(M/M{sub ⊙}) light-days for the Fe line-emitting regions, which is comparable to the size of the region generating the UV continuum (∼3-7 light-days). This may indicate that a significant part of the UV Fe II and Fe III emission originates in the quasar accretion disk.
Distribution of basal-expressed c-fos-like immunoreactive cells of the periaqueductal grey matter of the rat.
1996
The distribution of c-fos proto-oncogene expression has been studied in the periaqueductal grey matter (PAG) of non-intentional-stimulated rats by immunohistochemistry. A mean number of 53 +/- 9 Fos-like immunoreactive cells per hemiPAG, distributed into three groups, dorsolateral, lateral and ventrolateral, was found. The dorsolateral and the lateral groups appeared along the entire rostrocaudal PAG, whereas the ventrolateral group appeared only in the caudal half. These results reveal new data on the number and extent of the longitudinal columns within the hypothetical organization of the PAG. They also indicate a continuous activation of a significant population of neurones in the PAG, i…
New methods of delivery of amphotericin B.
1993
Fungal infections continue to be a major problem in the management of immunocompromised patients. Despite its formidable toxicity and treatment failures, amphotericin B is still the drug of choice for most of these infections. One strategy for reducing the toxicity of amphotericin B and thus permitting administration of higher doses is that of using less toxic formulations. Entrapping amphotericin B into liposomes or binding it to other substances reduces its toxicity to host cells, whereas the selective binding of amphotericin B to ergosterol preserves its toxicity to fungal cells. Adding fungus-specific antibodies to such liposomes may further increase the efficiency of drug targeting. Th…
The Cumulative Effect of Transient Synchrony States on Motor Performance in Parkinson's Disease.
2020
Bursts of beta frequency band activity in the basal ganglia of patients with Parkinson's disease (PD) are associated with impaired motor performance. Here we test in human adults whether small variations in the timing of movement relative to beta bursts have a critical effect on movement velocity and whether the cumulative effects of multiple beta bursts, both locally and across networks, matter.
