Usability Challenges in Surgical Simulator Training
2009
Surgical virtual reality simulators have been taken into use in order to improve surgical skills training. Emergence of simulators increases the need for research and knowledge related to usability of medical simulators. In this study usability of laparoscopic surgical simulator was researched experimentally through combined analysis. Data was gathered with heuristic evaluation, questionnaires, and interviews as well as recorded simulator parameters. Results suggest that the surgical simulator could be more efficient learning and training tool if usability issues such as support and error prevention were reconsidered in more detail. There also seem to be grounds for connecting user support …
Sustainable gardens: an evaluation tool for management and planning strategies.
2014
An evaluation tool was defined in order to manage gardens considering the six main directives of sustainability, from plant collections to public awareness and fruition.
Integrated Methods for Establishing the Sustainability of Urban Policies: Applying Ecological Footprint to the Municipal Solid Waste Management
2018
The Ecological Footprint (EF) method is applied here to assess alternative policies regarding the Municipal Solid Waste (MSW) management. This approach arises from two considerations. First, the MSW management certainly requires a great attention by politicians and technicians, due to its importance for effectively administrating and environmentally controlling urban contexts. On the other hand, the EF method, thanks to its holistic structure of analysis, supposedly provides a synthetic and effective measure of the sustainability of waste management systems, so allowing public administrations to prioritizing policies aimed at implementing environmental actions. Here the EF method is used fo…
The effect of chitosan on the bioaccessibility and intestinal permeability of acyclovir
2019
Chitosan is object of pharmaceutical research as a candidate permeability enhancer. However, chitosan was recently shown to reduce the oral bioavailability of acyclovir in humans. The effect of chitosan on two processes determining the oral bioavailability of acyclovir, bioaccessibility and intestinal absorption, was now investigated. Acyclovir's bioaccessibility was studied using the dynamic TNO gastro-Intestinal Model (TIM-1). Four epithelial models were used for permeability experiments: a Caco-2 cell model in absence and presence of mucus and both rat and porcine excised intestinal segments. Study concentrations of acyclovir (0.8 g/l) and chitosan (1.6 g/l and 4 g/l) were in line with t…
Symbolic Reductionist Model for Program Comprehension
2007
This article presents the main features of a novel construction, symbolic analysis, for automatic source code processing. The method is superior to the known methods, because it uses a semiotic, interpretative approach. Its most important processes and characteristics are considered here. We describe symbolic information retrieval and the process of analysis in which it can be used in order to obtain pragmatic information. This, in turn, is useful in understanding a current Java program version when developing a new version.

Un sistema de indicadores para el seguimiento y evaluación de la gestión sostenible del patrimonio cultural
2013
This paper describes the general procedure followed to build a system of indicators for monitoring and evaluating the Strategy for Culture and Development of Spanish Cooperation. Taking the Sustainable Management of Cultural Heritage as a reference, in this study an approach is made to questions relative to: 1) the process of evaluating a list of indicators by a panel of experts using the Delphi technique, 2) the definition and calculation of a relative operational index, 3) the process of indicator selection, and lastly, 4) how the selected indicators were assigned to form part of the basic or strategic dimension on which the system is structured. En este trabajo se describe el procedimie…
The diaptomid fauna of Israel (Copepoda, Calanoida, Diaptomidae), with notes on the systematics of Arctodiaptomus similis (Baird, 1859) and Arctodiap…
2014
Background: To date, only scarce information is available about the diaptomid copepods of the Middle East despite the ecological and biogeographical importance of the family Diaptomidae in the inland waters of the Holarctic region. Moreover, the taxonomic status of some of the taxa occurring in the area is in need of revision. We studied crustaceans collected from temporary and permanent lentic water bodies in Israel with the aim of providing an updated census of the diaptomid copepods occurring in the country. Furthermore, we morphologically and genetically analysed samples of Arctodiaptomus similis s.l. to shed light on its taxonomy. Results: Five diaptomid taxa were collected during this…
A simplified thermal model for the three way catalytic converter
2016
TAP 2016, 21st International Transport and Air Pollution Conference, LYON, FRANCE, 24-/05/2016 - 26/05/2016; A semi empirical model based on thermodynamic behaviour of a three way catalytic converter has been proposed to predict temperature evolution of the converter during the cold start. The model is based on energy and mass balance in the TWC considered as control volume. Parameters of the heat equations are identified separately using a step by step approach. Thermocouples have been inserted along the monolith canals to measure the axial evolution of temperature. Experiments on the engine test bench have been conducted to identify the parameters and to validate the model.
El efecto de las TIC en la adquisición de competencias. Un análisis por tipo de centro educativo
2016
El objetivo del trabajo es conocer la incidencia de estas Tecnologías de la Información y la Comunicación (TIC) en la adquisición de determinadas competencias y teniendo en cuenta la titularidad del centro (público o privado). En los últimos años el sistema educativo español ha experimentado la introducción masiva del ordenador e Internet en las aulas. En este contexto, el objetivo del trabajo es conocer la incidencia de estas Tecnologías de la Información y la Comunicación (TIC) en la adquisición de determinadas competencias y teniendo en cuenta la titularidad del centro (público o privado). Para ello se emplea una base de datos novedosa que incorpora información desglosada sobre la tenenc…
