Analysis and Improvement of Knowledge Management Processes in Organizations Using the Business Process Model Notation

[EN] Successful knowledge management is one of the main challenges for any kind of organization. This paper aims to enhance knowledge management processes within companies and institutions, by analyzing different processes that are part of common stages along all knowledge management lifecycles de-scribed in the literature. The processes have been modeled using the Business Process Model and Notation with a high abstraction level, in order to cover a wide range of organizations. The paper also presents a possible evolution and enhancement of knowledge management processes using the Business Process Model and Notation diagrams, including the use of superior and better perform-ing technological solutions to support knowledge management processes. As a result, we propose a set of improvements that can be extrapolated to other knowledge management-related business processes

Integración de las construcciones rurales en el paisaje: encuestas y conclusiones

Design and integration of rural buildings in landscape: surveys and conclusions. The visual and aesthetic aspect of any object is defined by its characteristics of colour, form, line and texture. Any elements of compositive reference such as its scale and spatial character could also be added. This research applies a new method for predicting the value of the integration of buildings into the landscape, based on psychological aspects and the capacities of modern computers that are able to analyse easily these attributes. The designer can analyse the visual elements, all of them divided and studied in the properties that define them

Kinetic study of pilot-scale supercritical CO2 extraction of rosemary (Rosmarinus officinalis) leaves

A definitive version was subsequently published in Journal of Supercritical Fluids, 55 (2011). http://dx.doi.org/10.1016/j.supflu.2010.09.030Rosmarinus officinalis (rosemary) extracts were obtained in a supercritical pilot-scale plant. Based on experimental information available in the literature for analytical or low-scale processes, extraction temperature and pressure were selected to be 313 K and 30 MPa. At these extraction conditions, the kinetic behavior of the pilot-scale overall extraction curve were determined with respect to yield, antioxidant activity and carnosic acid content. The overall extraction curve was represented using Sovova’s model; the average deviation between measured and calculated yields was lower than 2%. Mass transfer coefficients in the fluid and solid phases were determined and were compared with previous data reported in the literature for low-scale rosemary supercritical extraction. A two-stage depressurization procedure was accomplished and the effect of both on-line fractionation and extraction time on the antioxidant activity of the samples collected was studied. The antioxidant activity of the different fractions could be straight correlated with the carnosic acid content with a regression coefficient of 0.92This work has been financed by Universidad Autónoma de Madrid and Comunidad Autónoma de Madrid (ALIBIRD-S2009/AGR-1469) and project FUN-C-FOOD, CSD2007-00063 (CONSOLIDER-INGENIO) from Ministerio de Ciencia e Innovación, Spain

Las nuevas construcciones ante la conservación del paisaje tradicional: un acercamiento a su estudio en el Páramo Leonés

Los paisajes se encuentran salpicados de numerosas edificaciones que influyen en la visualización que se tiene de ellos. Las construcciones rurales son un tipo de edificio que, por sus dimensiones y localización, influyen notablemente en la apreciación estética de la escena. Es notoria la importancia creciente en nuestro país del paisaje como recurso natural y, por tanto, de las construcciones como factor que afecta a la belleza paisajística. La sociedad en general, y los técnicos y proyectistas en particular, deberían tener en cuenta que la elección de los materiales de construcción, el emplazamiento y las relaciones de texturas y colores son consideraciones primordiales para el diseño de edificios rurales. Son elementos que intervienen en la conservación de los ecosistemas y en la potenciación del turismo rural, una de las principales vías económicas para muchas regiones españolas

Las nuevas construcciones antes la conservación del paisaje: un acercamiento a su estudio. Caso particular del páramo leonés

El paisaje es un recurso natural que cada vez aparece considerado con mayor profusión en la redacción de proyectos, y que debe ser protegido y conservado ante la construcción de Intervenciones antrópicas. Por tanto, el impacto visual ha de ser estudiado como una parte primordial en los estudios generales de impacto ambiental. Las nuevas tecnologías deben contribuir a ello proporcionando herramientas informáticas que realicen simulaciones y reproducciones de la realidad con alto grado de fidelidad

Single-molecule kinetic energy of condensed normal deuterium

8 págs.; 9 figs.; 1 tab.Inelastic scattering of 300-meV neutrons allows the study of the liquid (T=20 and 30 K, saturated vapor pressure) and solid (T=4.2 K, saturated vapor pressure) phases of the normal deuterium mixture (2/3 o-D2+1/3 p -D2) in the region of momentum transfer where a single-molecule response is expected. The spectra are analyzed within the impulse approximation and assuming Gaussian momentum distributions for the translation of the molecules. For the solid, the estimated value of the single-molecule average kinetic energy does not compare unfavorably with those obtained scaling experimental results in parahydrogen solids. In the liquid state, substantial departures seem to exist from the classical liquid behavior, even if up to second-order quantum corrections are taken into account. ©1996 American Physical SocietyThis research has been made possible in part by the Spanish DGICYT through Grant No. PB92-0015.Peer Reviewe

Thermal transport in glassy selenium: The role of low-frequency librations

7 págs.; 3 figs.The experimental curves giving the temperature dependence of the thermal conductivity of glassy selenium are considered in detail. The observed behavior can be taken into account quantitatively if the densities of states for short-wavelength phonons as well as for low-energy librations arising from computer simulations are used for the calculations. In particular, it is shown that the lowest frequency excitations of a chain of selenium atoms can give due account of the plateau observed at temperatures about 2-10 K. The implications of the present findings for the current debate regarding the mechanisms for thermal transport in glasses are finally discussed. © 1994 The American Physical Society.This work has been supported by DGICYT Grant No. PB92-0114-C03Peer Reviewe
