La gestión del conocimiento y el capital intelectual

Los principios contables no contemplan una parte importante del valor de una empresa: los activos intangibles. Muchas empresas se cotizan en bolsa por un valor mucho mayor que la simple suma de capital más reservas. La diferencia está en un conjunto de valores tales como una gran cartera de clientes, la capacidad de colaborar con otros socios comerciales, sus conocimientos, habilidades, valores y actitudes de las personas que forman parte de la empresa. Se destaca la importancia de una gestión profesionalizada de estos activos para que se mantengan o se aumente su valor con el paso del tiempo

Desarrollo e instrumentación de un sistema exportable de monitorización y control en tiempo real de procesos de tratamiento superficial de aceros con láser

Los tratamientos de temple superficial de metales son ampliamente utilizados en la industria para mejorar las propiedades mecánicas y tribológicas de componentes mecánicos. Estos tratamientos pueden ser realizados mediante láseres de potencia, pero los resultados obtenidos dependen de muchos factores que impiden asegurar la repetibilidad del mismo. El objetivo de la tesis es contribuir a mejorar el resultado final obtenido en estos procesos y garantizar su repetibilidad mediante la introducción de un control del proceso en tiempo real. Para que el garantizar su repetibilidad mediante la introducción de un control del proceso en tiempo real. Para que el sistema desarrollado sea totalmente exportable a la industria se necesita que tanto los equipos propuestos sean utilizables dentro de un ambiente industrial, que se puedan integrar plenamente con equipos industriales y que los programas desarrollados o utilizados no impliquen un tiempo excesivo de formación de personal. Con esta finalidad, se analiza como la combinación de modelos matemáticos y técnicas experimentales pueden constituir una herramienta eficaz con la que se pueden minimizar los costes de los experimentos así como predecir la naturaleza de las modificaciones que estos tratamientos causan en los materiales tratados. Para poder comparar los resultados experimentales con los obtenidos de los modelos se necesita poner de acuerdo los valores de anchura de haz y energía absorbida por la pieza para lo que en la tesis se proponen dos soluciones para su determinación. Se caracteriza el haz láser y pirómetro utilizado para medir la temperatura superficial y se diseña un dispositivo para su sujección y alineación. Por último, se sintoniza el sistema de control y se diseñan pruebas específicas para validar la idoneidad del sistema

Colour changes in Galician granitic stones induced by UV Nd:YAG laser irradiation

Presentado en International Conference Lacona VII, Madrid, Spain, 17-21 September 2007[Resumen]: estudio sobre el cambio de color del granito gallego al limpiarlo mediante láser ultravioleta[Abstract] Laser cleaning has become a high profile and accepted specialized cleaning technique for most stone types. Given that local natural building stone in our region, Galicia (North West of Spain) is granite, our interest was focused on the response of this stone type to laser cleaning. The aim of this work is to determine the change in colour as index of the response of galician granites to UV-Nd:YAG laser exposure. For this purpose samples of commercial granites from different quarries were irradiated at increasing fluences. Colour changes were determined through the analysis of digital images and expressed in the L*a*b* and L*h*C* colour models. The results enable the establishment of application limits of laser cleaning to these material

An Economic Analysis of An Innovative Floating Offshore Wind Platform Built with Concrete: The SATH® Platform

[Abstract] The goal of this work is to carry out an economic analysis of a novel floating offshore wind structure, of which the main material is concrete: the SATH® platform. It takes a step forward in floating marine wind energy research, in which traditional platforms are mainly composed of steel. The technique to calculate the costs of the platform and the economic parameters to decide if the farm is economically feasible are explained in the paper. This case study analyzes a possible farm of 500 MW located in Portugal and several scenarios considering different electric tariffs and capital costs (Scenario 1: electric tariff of 50 €/MWh and 6% of capital cost; Scenario 2: electric tariff of 50 €/MWh and 8% of capital cost; Scenario 3: electric tariff of 150 €/MWh and 6% of capital cost; Scenario 4: electric tariff of 150 €/MWh and 8% of capital cost). Results show the economic feasibility of a farm with the characteristics of Scenarios 3 and 4. This work is significant in order to provide a new approach to analyzing traditional floating offshore wind structures, which can represent a path towards the future of floating offshore renewable energy technologies.European Commission; EAPA_344/2016This research was funded by EAPA_344/2016 ARCWIND project, co-financed by the European Regional Development Fund though the Interreg Atlantic Area Programme

Servicio profesional de monitorización ambulatoria de la presión arterial (MAPA) en farmacia comunitaria. Identificación de hipertensión no controlada de bata blanca

Varón de 68 años diagnosticado de hipertensión arterial hace 6 meses. Desde ese momento lo hemos incluido en nuestro Servicio Profesional Farmacéutico Asistencial de Medida y Control de la presión arterial (PA). Los sucesivos valores de PA obtenidos mediante medida aislada en farmacia comunitaria (MAFC) han estado dentro de la normalidad. Actualmente el paciente tiene programada una intervención quirúrgica en el servicio de oftalmología que no se ha podido realizar por presentar sucesivos valores elevados de PA (≥180/100 mmHg) en consulta médica de atención primaria y especializada. El paciente refiere ponerse “muy nervioso” al acudir al médico. Sospechamos que los valores elevados de PA en consulta son compatibles con un “efecto de bata blanca” (EBB). Acordamos con él y su médica de atención primaria la realización de una monitorización ambulatoria de presión arterial (MAPA) con el objetivo de descartar el EBB. Una vez obtenidos los resultados, identificar el fenotipo del paciente y observar que los valores de PA de la MAPA están dentro de la normalidad, se realiza una interconsulta con oftalmología. A la vista de los resultados el oftalmólogo decide realizar la operación, que se lleva a cabo con éxito

Compositional depth profiles of gilded wood polychromes by means of LIBS

[Resumen] Se analizan las diferentes capas existentes en retablos de maderas policromadas del periodo barroco. Se distinguen la capa base y las posteriores hasta el acabado mas superficial. Se aprecian las diferentes técnicas aplicadas en función de la procedencia y del autor que las ha realizado.[Abstract] Gilded wood polychromes are important artistic expressions in Galicia (NW Spain) during the baroque period. The variety of techniques applied in gilded ornamentation and the possible existence of products of previous interventions make difficult the restoration process of these artworks which frequently include the removal of a brass-based paint (purpurin) added to cover the lack of gold leaf. The aim of this work is the characterization by means of LIBS of the different layers in gilded wood polychromes. For this purpose small pieces taken from two baroque altarpieces were analyzed using a Nd:YAG laser source operating at the wavelength of 355 nm to obtain characteristic LIBS spectra and compositional depth profiles.Xunta de Galicia; PGIDIT06CCP00901C

Configuration Methodology for a Green Variety Reef System (AR group) Based on Hydrodynamic Criteria – Application to the Ría de Ares-Betanzos

Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG[Abstract] For the evolution and development of artificial reefs to attain the expected results, hydrodynamics is emerging as a key factor that must be taken analyzed in detail. In particular, thanks to the hydrodynamics of a given coastal area, suitable water circulation and velocity in the reef's interior can increase the yield and the renewal of nutrients favourable for larval settlement, along with reducing the sedimentation. This document proposes a methodology for determining the geometry of an artificial reef group adapted to the specific characteristics of the selected zone of installation, the Ría de Ares-Betanzos (NW Spain), based on hydrodynamic criteria by defining the Artificial Reef Tool (ART). The starting point of the ART tool is the existing reef model or AR unit's design –a modular construction with productive and protective features. Then a high-resolution hydrodynamic circulation model (HCM) is developed allowing the high-resolution site-specific computation of the flow pattern in the selected area. Finally, the results obtained are used as input for a hydrodynamic model for food delivery prediction (HMFDP), allowing the estimation of the food supply to each module. The results obtained lead to the definition of the geometry of the reef group.The authors gratefully acknowledge the financial support from the regional government of Galicia, Xunta de Galicia, through the project CN-10MMA003CT.

Motor Fluctuations Development Is Associated with Non-Mostor Symptoms Burden Progression in Parkinson's Disease Patients : A 2-Year Follow-Up Study

The aim of the present study was to analyze the progression of non-motor symptoms (NMS) burden in Parkinson's disease (PD) patients regarding the development of motor fluctuations (MF). PD patients without MF at baseline, who were recruited from January 2016 to November 2017 (V0) and evaluated again at a 2-year follow-up (V2) from 35 centers of Spain from the COPPADIS cohort, were included in this analysis. MF development at V2 was defined as a score ≥ 1 in the item-39 of the UPDRS-Part IV, whereas NMS burden was defined according to the Non-motor Symptoms Scale (NMSS) total score. Three hundred and thirty PD patients (62.67 ± 8.7 years old; 58.8% males) were included. From V0 to V2, 27.6% of the patients developed MF. The mean NMSS total score at baseline was higher in those patients who developed MF after the 2-year follow-up (46.34 ± 36.48 vs. 34.3 ± 29.07; p = 0.001). A greater increase in the NMSS total score from V0 to V2 was observed in patients who developed MF (+16.07 ± 37.37) compared to those who did not develop MF (+6.2 ± 25.8) (p = 0.021). Development of MF after a 2-year follow-up was associated with an increase in the NMSS total score (β = 0.128; p = 0.046) after adjustment to age, gender, years from symptoms onset, levodopa equivalent daily dose (LEDD) and the NMSS total score at baseline, and the change in LEDD from V0 to V2. In PD patients, the development of MF is associated with a greater increase in the NMS burden after a 2-year follow-up
