Education for development in the university context. Why and for what?
2021
La educación para el desarrollo se ha venido popularizando progresivamente en las universidades españolas en paralelo con la extensión de la cooperación para el desarrollo entre estas. La educación para el desarrollo se ha visto como una oportunidad para promover el compromiso social de la Universidad y fomentar valores de solidaridad y justicia a través de la formación universitaria. La educación para el desarrollo ha puesto de relieve el componente educativo de la Universidad, a menudo subsumido por el afán formativo. Sin embargo, el alcance de la educación para el desarrollo y, sobre todo, su transversalización en los programas de estudio universitarios siguen siendo muy limitados. El ob…

Bibliotecas abiertas. El programa de visitas de la Biblioteca Valenciana Nicolau Primitiu. Información bibliográfica y difusión bibliotecaria. Biblio…
2022
En un contexto de reducción de la financiación pública y de cambio de paradigma en el acceso a la información, la supervivencia de las bibliotecas está ligada a un mayor y mejor conocimiento de la ciudadanía de sus colecciones, productos y servicios. En este estudio se analiza el programa de visitas de la Biblioteca Valenciana Nicolau Primitiu, sus características, destinatarios y tipologías, así como los resultados alcanzados hasta ahora. In a context of reduced public funding and a paradigm shift in access to information, the survival of libraries is linked to greater and better knowledge by citizens of their collections, products, and services. This study analyzes the visits program of t…
Simulations of non-spherical particles suspended in a shear flow
2000
The lattice-Boltzmann method was used to investigate the effects of the shape and concentration of the particles on the rheological properties of non-Brownian suspensions for non-zero Reynolds numbers. Several case studies were analyzed and the methods used were found to give accurate predictions for these systems. The viscosity of suspensions of both spherical and non-spherical particles was determined as functions of shear rate and concentration of particles. It was shown that, for high shear rates, shear thickening appears. This phenomenon is particularly pronounced for particles of irregular shape.
Testing a theoretical resistance law for overland flow under simulated rainfall with different types of vegetation
2020
Abstract In this paper a recently theoretically deduced flow resistance equation, based on a power-velocity profile, was tested using data collected for overland flow under simulated rainfall carried out in plots with vegetation. The available data were obtained exploring a wide range of rainfall intensities (from 60 to 181 mm h−1) and slopes (from 3.6 to 39.6%), and with four different types of vegetation. The database, including measurements of flow velocity, water depth, cross sectional flow area, wetted perimeter and bed slope, was divided in four datasets (one for each vegetation type), which allowed the calibration of the relationship between the velocity profile parameter Γ, the slop…
Assessing an overland flow resistance approach under equilibrium sediment transport conditions
2021
Abstract In this study, for the first time, a theoretically deduced flow resistance equation was tested for an overland flow under equilibrium sediment transport conditions using available experimental data by Liu et al. for five Chinese soils. Initially the relationship among the velocity profile parameter Γ, the channel slope, the flow Reynolds number, the Froude number and the sediment concentration was calibrated using 90 measurements of the available database (Loessial, Cinnamon and Black soil) and tested by other 60 measurements (Red and Purple soil). The results proved that the Darcy–Weisbach friction factor can be accurately estimated by the proposed theoretical approach, with error…
Testing a theoretically-based overland flow resistance law by Emmett’s database
2021
Abstract The main aim of this paper was to test a recently theoretically deduced flow resistance equation, based on a power-velocity profile, using a wide database of available measurements carried out in laboratory and field experimental runs with overland flow under simulated rainfall. In comparison with previous calibrations and validations of this theoretically deduced flow resistance equation, the used database by Emmett is characterized by a wide range of rainfall intensities (from 79.2 to 303.5 mm h−1 for laboratory runs and from 178.3 to 215.9 mm h−1 for field investigations) and bed slopes (from 0.33 to 17% for laboratory runs and from 2.9 to 33.2% for field investigations). For th…
El color del camaleón: un testimonio valiente para la sociedad chilena
2017
The film El color del camaleón (2017) by Andrés Lübbert, which has great cinematic and content merits, can be considered as an important part of Chilean films on memory and post-memory. I focus on its contribution to Chilean memory and the reconstruction of the truth through the unveiling, in particular, of cruel methods of forced recruitment used by the dictatorship’s secret services. They were used as a further tool to instill terror in society, and as a way of submission and control of the population.
The red tooth hypothesis: A computational model of predator-prey relations, protean escape behavior and sexual reproduction
2009
This paper presents an extension of the Red Queen Hypothesis (hereafter, RQH) that we call the Red Tooth Hypothesis (RTH). This hypothesis suggests that predator-prey relations may play a role in the maintenance of sexual reproduction in many higher animals. RTH is based on an interaction between learning on the part of predators and evolution on the part of prey. We present a simple predator-prey computer simulation that illustrates the effects of this interaction. This simulation suggests that the optimal escape strategy from the prey's standpoint would be to have a small number of highly reflexive, largely innate (and, therefore, very fast) escape patterns, but that would also be unlearn…
