Educational Activities for Acquiring Skills in the EEES adapted Degrees

[EN] The main objective of this paper is to describe the performance of a serial of training activities focused on the acquisition of skills by different groups of undergraduate students related to science as a branch of knowledge. Specifically, we used those activities where students receive knowledge, such as theoretical classes (T), computational (PC) and laboratory (PL) sessions, exercises (P), ECTS tutorials and bachelor thesis (TFG). Among the different activities, it must also be highlighted the undergraduate dissertation. The activities were conducted in different courses of the Chemistry degree of the University of Extremadura, in order to obtain information from the different competences that appear in the verification report of this title. Finally, the students filled out a survey giving their opinion about the skills acquired in each of the activities. The results of the experience is that students achieve most of the skills considered in the title. Likewise, the results from the activities considered show that not all skills are achieved and other activities should be considered to cover those deficiencies. The activity that most contributes to the acquisition of transversal competences are laboratory practices, while for specific skills, the activities developed with large group of students (T and P) are the most significant. TFG is the activity that best covers most of competences, especially Basic and General.This work was sponsored by the Consejería de Infraestructuras y Desarrollo Tecnológico de la Junta de Extremadura (Project GR15003).Tolosa, S.; Hidalgo, A.; Ojalvo, EA.; Guiberteau, A.

The prolific polytypism of silicon carbide

A worked example of polytypism is presented, aimed at assisting undergraduates in the learning and instructors in the teaching of this topic. In particular, this crystallography concept, not necessarily obvious for beginners, is illustrated pedagogically using to that end the model case of the prolific polytypism of silicon carbide (SiC). On the basis of concepts that are easily assimilated by students (i.e. simple topological constraints) this article first presents a unified description of the polytypism phenomenon in SiC that allows one to understand without difficulty the existence of its numerous polytypic variants and how they develop. Then the various notations used to designate these different polytypes are described, and finally the crystal structures of the most common are discussed. This worked example is thus expected to contribute to motivating undergraduates in the study of a crystallography topic that often is not treated in sufficient depth in class.Ministerio de Ciencia y Tecnología MAT2010-1684

Bioinspired design of triboceramics: Learning from the anisotropic microfracture response of dental enamel under sliding contact

[EN] In the quest for novel ceramics for tribological applications via bioinspired design, the differences in the fracture modes that arise upon scratching relevant locations of ceramic-like tooth enamel are investigated. It is found that fracture initiates from weak rod-sheath interfaces at relatively low loads, independent of the sliding direction. However, the geometry and propagation of the cracks depends on the orientation of the interfaces relative to the maximum tensile stress: scratching along the occlusal surface propagates approximately sinusoidal cracks, parallel to the sliding direction, while scratching along the cross-section produces straight cracks that propagate normal (scratch parallel to occlusal surface) or parallel (scratch perpendicular to occlusal surface) to the sliding direction. The formation of cracks is hindered in scratching near the enamel-dentine junction. Implications for the microstructural design of triboceramics (bulks and coatings) with improved durability are discussed.The authors wish to thank Dr Florencio Monje Gil for kindly providing tooth specimens from his clinic (CICOM, Centro de Implantologia Cirugia Oral y Maxilofacial, Badajoz, Spain).

Three Case Studues of the Application of Energy Systems Optimization Best Prectices for Automatic Demand Response

This paper summarizes three case study buildings located in Austin, Texas that were selected for inclusion in a review of the demand reduction program of the utility company Austin Energy. The buildings studied include a city government office building, a grocery store, and an industrial research office building containing high density data processing and server areas. This paper discusses the influence of the demand reduction measures on the indoor space conditions and HVAC system equipment, and cautionary notes regarding implementation for each measure. The objective of this study is to assess the feasibility of these facilities entering Austin Energy's demand reduction program
