Abstract

The Internet as a socio-telematic media should generate and increase educational processes. Teaching and reading practice in the Internet is very necessary in order to learn to interact critically. The development of skills to explote its potencial for a deep and thoughtful comprehension with the transference to other reading situations, interaction and navigation will help for an autonomous and imaginative person.

Abstract

This paper presents the implementation of a Cone Penetration Test (CPT)-based methodology to identify fluid-like tailings in the Tailings Storage Facility (TSF) pond to support a TSF deconstruction. The TSF discussed in this paper was partially raised upstream and classified as very high risk due to its location, next to a creek and a short distance to the downstream community. The owner's preferred mitigation strategy was to proceed with the TSF deconstruction. To inform the deconstruction planning, a comprehensive geotechnical site investigation was conducted, which included CPTu and boreholes with continuous thin wall tube sampling from a floating platform. The investigation identified tailings in the pond as high plasticity clays (CH) with a geotechnical fines content exceeding 95 %. The CPT results indicated low tip resistance, nearly linear pore pressure measurements, and minimal sleeve friction, suggesting the presence of fluid-like tailings in a significant portion of the TSF. The implementation of this methodology allowed to systematically confirm the presence of fluid-like tailings across the pond and define their extent. This information supported the owner’s decision to employ mechanical excavation taking advantage of the tailings flowability. The observations made during the tailings excavation confirmed a good agreement between the CPT assessment and the actual material behaviour. These findings underscore the efficacy of the CPT-based method in guiding safe TSF deconstruction projects

Abstract

The present article offers a proposal of deconstruction of the news to adapt it to the new media placing the focus in the audiovisual -up of the textual-, incorporating the key ingredients of the digital environment (multimediality, hypertextuality, interactivity) and fixing paths through links and comments that allow both personalization with different levels of deepening as the integration of readers-users in the new communication paradigm of the digital world. Thus, we propose to change the inverted pyramid that has marked the rules of Journalism in the last century for a Rubik’s Cube that still use the 5W as a gateway to the transmedia news, in which each question can work as a hook and activate the multimedia and interactive itinerary that guides us inside the renewed information cube
