La gamificación como herramienta para reducir los accidentes laborales viales en pymes y autónomos
2018
El uso del vehículo constituye un medio de transporte imprescindible para muchos trabajadores, que lo utilizan para sus desplazamientos a sus lugares de trabajo o en el desarrollo de su actividad profesional. Actualmente en España el 13,45% de los accidentes laborales son de tráfico, siendo importante para su prevención invertir en formación e incorporar la cultura de la seguridad vial como parte de la actividad corriente de la organización. En este trabajo se propone el uso de la gamificación como herramienta para la formación y concienciación de los trabajadores autónomos y pymes en el esfuerzo por reducir el número de accidentes laborales viales en sus organizaciones. Para ello se descri…
Biological properties of extracellular vesicles and their physiological functions
2015
The authors wish to thank Dr R Simpson and Dr D Taylor for critical reading of the manuscript and acknowledge the Horizon 2020 European Cooperation in Science and Technology programme and its support of our European Network on Microvesicles and Exosomes in Health & Disease (ME-HaD; BM1202 www.cost.eu/COST_Actions/bmbs/Actions/BM1202). In the past decade, extracellular vesicles (EVs) have been recognized as potent vehicles of intercellular communication, both in prokaryotes and eukaryotes. This is due to their capacity to transfer proteins, lipids and nucleic acids, thereby influencing various physiological and pathological functions of both recipient and parent cells. While intensive invest…
MALDI MS imaging as a powerful tool for investigating synovial tissue
2012
To identify and image protein biomarker candidates in the synovial tissue of patients with rheumatoid arthritis (RA) and patients with osteoarthritis (OA).A novel matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry (IMS) technique was applied to the analysis of synovial tissue. Patients were classified according to the American College of Rheumatology (ACR) criteria for RA. Frozen sections were stained to obtain morphological data. Serial sections were desiccated, and spotted with matrix for MALDI analysis. Ions generated by laser irradiation of the tissue were separated in time, based on their m/z ratio, and were subsequently detected. IMS was used in a 'profiling…
Psicología aeronáutica en España. Una historia y una panorámica actual.
2005
Se ofrece una reconstrucción histórica de la Psicología Aeronáutica, desde la perspectiva constructivista y apoyándose en la exhaustiva revisión de fuentes de archivo y legislación. El estudio marca tres épocas nítidamente diferenciadas, vinculada cada una de ellas con un programa de investigación perfectamente definido. En la época de los pioneros (1900-1936) se fue configurando un modelo de selección anclado en el análisis de tarea y en la teoría de la predisposición al accidente, que utilizaba para la exploración el aparataje típico de los primeros laboratorios evaluaban aptitudes y destrezas, solo de forma incipiente se planteaba el uso de pruebas más holistas que exploraban la personal…
Humoral autoreactivity directed against surfactant protein-A (SP-A) in rheumatoid arthritis synovial fluids.
2000
SUMMARY SP-A is found principally in the lung, and has been associated with lamellar bodies also found in the synovial joint. Both SP-A and C1q contain collagen-like regions, and SP-A and C1q have some structural similarities, both having a globular head region and a collagen-like tail. Here we are able to show that (i) autoreactivity to SP-A, as expressed by IgG and IgM autoantibodies, is present in synovial fluid (SF) isolated from patients with rheumatoid arthritis (RA); (ii) in absorption experiments only a limited degree of cross-reactivity between autoantibodies reactive with C1q and SP-A is observed; (iii) there is no cross-reactivity between autoantibodies reactive with type II coll…
Pulmonary metastasectomy in soft tissue sarcomas: a systematic review
2021
Background Soft tissue sarcoma (STS) tend to metastasis to the lungs. Pulmonary metastasectomy seems to be a common practice always when plausible. The objective of this article was to review systematically the results of a literature search on pulmonary metastasectomy for STSs published in the last ten years and to offer a brief overview about the current practice as well. Methods Eight retrospective studies published in the period 2010-2020, which included patients with pulmonary metastases and metastasectomy were selected. Indication for surgery, survival rate and factors influencing survival were the primary outcomes, while further interesting findings in the studies were also collected…
Professional drivers and private drivers from Bogotá: Diagnosis of sociodemographic conditions and general well-being [exploratory analysis]
2018
espanolA pesar que los accidentes de trafico son reconocidos mundialmente como un problema de salud publica y que en Colombia representan la segunda causa de muerte violenta, hay una falta de investigacion en torno al tema, hecho que senala la importancia de iniciar acciones concretas. En consonancia con lo anterior, el objetivo de la presente investigacion fue estudiar dos tipos de poblacion de conductores, a saber, conductores profesionales y particulares en la ciudad de Bogota, mediante un analisis y comparacion de su situacion sociodemografica y de salud general. Con tales fines, una investigacion de corte transversal fue llevada a cabo, en la que participaron 500 conductores (250 profe…
Elements of General Representation Theory
1982
In Chapter V, classical representation theory was studied. This is the theory of the group-ring KG and the KG-modules, where K is an algebraically closed field of characteristic 0. (Many theorems remain valid under the hypothesis that K is algebraically closed and that char K does not divide the order of G). In this case, KG is semisimple and all KG-modules are completely reducible. For many purposes it is therefore sufficient to handle the irreducible representations.
Mineralogical and chemical variability of fluvial sediments 2. Suspended-load silt (Ganga–Brahmaputra, Bangladesh)
2011
Sediments carried in suspension represent a fundamental part of fluvial transport. Nonetheless, largely because of technical problems, they have been hitherto widely neglected in provenance studies. In order to determine with maximum possible precision the mineralogy of suspended load collected in vertical profiles from water surface to channel bottom of Rivers Ganga and Brahmaputra, we combined Raman spectroscopy with traditional heavy-mineral and X-ray diffraction analyses, carried out separately on low-density and dense fractions of all significant size classes in each sample (multiple-window approach). Suspended load resulted to be a ternary mixture of dominant silt enriched in phyllosi…
Cyclicity of Triassic to Lower Jurassic continental red beds of the Argana Valley, Morocco: implications for palaeoclimate and basin evolution
2000
Abstract Cyclical playa deposits form a prominent part of the continental clastic succession of the Argana Valley, Western High Atlas of Morocco. The red beds formed in Triassic to Lower Jurassic times during rifting of the North American and African plates. Detailed stratigraphic work revealed asymmetrical, metre-scale cycles in mudstone-dominated successions that constitute the intermediate and upper portion of the basin fill. Sedimentary cycles commonly comprise ephemeral lake shales at the base, playa mudflat mudstones in the intermediate part, and both fluvial and aeolian sandstones at the top. Cycles of the Aglegal Member (T4) are mainly characterized by analcime-rich playa mudflat de…
