Los entornos Lego y Logo en Robotica Educativa

In some recent projects aimed at renewing the methodology for an integrated science, mathematics and computer teaching, where the introduction of educational robots in school may help to make learning more meaningful and motivating, some questions raise: what interest offers to introduce robotics in primary and secondary education? What is learned through the activities of Robotics? How to design experiences of "good learning" (constructivist) with robots? This paper attempts to answer the above questions, showing some discussions which compare the educational potential of LEGO Mindstorms environment for building and programming a physical robots with respect to LOGO softwares, with their virtual robot (the "turtle "). This analysis is conducted using as reference the "anthropological theory of didactics.

DataSheet_1_Surface chlorophyll anomalies induced by mesoscale eddy-wind interactions in the northern Norwegian Sea.docx

The substantial productivity of the northern Norwegian Sea is closely related to its strong mesoscale eddy activity, but how eddies affect phytoplankton biomass levels in the upper ocean through horizontal and vertical transport-mixing has not been well quantified. To assess mesoscale eddy induced ocean surface chlorophyll-a concentration (CHL) anomalies and modulation of eddy-wind interactions in the region, we constructed composite averaged CHL and wind anomalies from 3,841 snapshots of anticyclonic eddies (ACEs) and 2,727 snapshots of cyclonic eddies (CEs) over the period 2000-2020 using satellite altimetry, scatterometry, and ocean color products. Results indicate that eddy pumping induces negative (positive) CHL anomalies within ACEs (CEs), while Ekman pumping caused by wind-eddy interactions induces positive (negative) CHL anomalies within ACEs (CEs). Eddy-induced Ekman upwelling plays a key role in the unusual positive CHL anomalies within the ACEs and results in the vertical transport of nutrients that stimulates phytoplankton growth and elevated productivity of the region. Seasonal shoaling of the mixed layer depth (MLD) results in greater irradiance levels available for phytoplankton growth, thereby promoting spring blooms, which in combination with strong eddy activity leads to large CHL anomalies in May and June. The combined processes of wind-eddy interactions and seasonal shallowing of MLD play a key role in generating surface CHL anomalies and is a major factor in the regulation of phytoplankton biomass in the northern Norwegian Sea.</p

T-GameL3: development of an interdisciplinary lifelong e-learning experience in an international context

The T-GaME L3 project (Teaching computer Graphics and MultimEdia LifeLong Learning, http://t-gamel3.ub.edu.ar) intends to provide a learning environment for computer graphics and multimedia contents mainly focussed on computing and architecture domains. It is based on the cooperation of several higher education institutions from Europe and Latin America by means of technologies, methods and learning processes related to distance learning. The developed course contents are being used in a pilot experiment, from March to July 2006, involving a selected group of post-graduate students from all participating countries. The available courses have been customized to the different national educational environments by sharing the digital teaching resources of project members. The designed program has taken into account ECTS (philosophy and accounting) and Diploma Supplement recommendations. For now, the participating institutions have reached a multilateral agreement to support this effort. Evaluation results will be available by the end of July and we hope to: Demonstrate the feasibility of the process. Show the benefits for students/teachers (flexible methodology, extensive and coherent educational offer). Offer ways of carrying out lifelong learning to the participating institutions and the EU. Before the end of the project an external quality evaluation will be made in order to meet current European quality standards. In the long term, the partners intend to extend this cooperation to other institutions in order to reach a sustainable academic program of continuous educatio

Feasibility and Safety of Tethered Capsule Endomicroscopy in Patients With Barrett’s Esophagus in a Multi-Center Study

Tethered capsule endomicroscopy (TCE) involves swallowing small tethered pill that implements optical coherence tomography (OCT) imaging, procuring high resolution images of the whole esophagus. Here, we demonstrate and evaluate the feasibility and safety of TCE and a portable OCT imaging system in patients with Barrett’s esophagus (BE) in a multi-center (5-site) clinical study
