The PARSIFAL (Probabilistic Approach to pRovide Scenarios of earthquake Induced slope FAiLures) method was applied to the survey of post-earthquake landslides in central Italy for seismic microzonation purposes. In order to optimize time and resources, while also reducing errors, the paper-based method of survey data sheets was translated into digital formats using such instruments as Tablet PCs, GPS and open source software (QGIS). To the base mapping consisting of Technical Regional Map (Carta Tecnica Regionale—CTRs) at the scale of 1:10,000, layers were added with such sensitive information as the Inventory of Landslide Phenomena in Italy (Inventario dei Fenomeni Franosi in Italia—IFFI), for example. A database was designed and implemented in the SQLite/SpatiaLite Relational DataBase Management System (RDBMS) to store data related to such elements as landslides, rock masses, discontinuities and covers (as provided by PARSIFAL). To facilitate capture of the datum on the ground, data entry forms were created with Qt Designer. In addition to this, the employment of some QGIS plug-ins, developed for digital surveying and enabling of quick annotations on the map and the import of images from external cameras, was found to be of considerable use.

The first year research has aim to: (1) describe the learning assessment process of the speaking theory subject and (2) design the theorethic model of authentic assessment in speaking competence. The method used in the research is Research and Development method, i.e. the research method is used to produce certain product, and to test the effectiveness of the product. The results of the research are: (1) the assessment activity of the students’ speaking competence who takes the speaking theory subject have the characteristics of authentic assessment. It is based on the result of the curriculum review which has impact to the syllabus adjustment in directing to the teachers’ need at school. Therefore, the speaking competence assessment which focuses on the speaking ability, nowadays its academic competence focus is broading. In addition, the audiences’ affective respon is used as the assessment consideration; (2) the theoretic model of speaking competence assessment can be described that the speaking competence assessment is divided as two step categories, they are the process and the result assessment. The portofolio assessment is the most theorithic assessment tecnique which considered as it appropriate to gain the students’ speaking competence development. The result of the assessment is divided into two tests, i.e the middle semester test and the final semester test. The middle semester test is used to know the student’s competence which has closed relation to the speaking theories because the students have to mastery the speaking competence in order to practice the speaking competence, the students’ must also have to teach it. The final semester test is conducted to know the students’ competence in the speaking practice which can be conducted by the three techniques, they are group, peer, and individual technique. The tehcniques can be applied based on the needs and the characteristic of the tested competence.

Indirect bioleaching is a biotechnology that presents important advantages when apply to bioprocessing of zinc and zinc polymetallic concentrates such as high metals recovery, fast kinetic of 4-5 hours to get full metals extraction, sulphur oxidation to elemental sulphur (avoiding sulphuric acid generation, while pyrite mineral remains untouched), and use of conventional reactors (aeration is not required) and normal process equipments. On the other hand, the development of high-efficiency bioreactors for ferrous iron bio-oxidation based on flooded fixed-bed model has opened the way to succeed in the potential commercial application of this innovative bio-hydrometallurgical technology, being especially attractive to benefit zinc and lead bulk or polymetallic concentrates containing other valuable metals like silver. In addition, a great variety of concentrates is feasible to be processed, e.g. in the range of 15% to 60% Zn and Pb metals content. That aim, within European Biomine project, for the first time in biohydrometallurgy field, indirect bioleaching technology applied on Zn/Pb polymetallic concentrates has been demonstrated in continuous in an integrated pilot plant at Tecnicas Reunidas’ (TR) R&D Centre in Madrid (Spain) producing electrolytic SHG zinc plates. Overall zinc recovery in the integrated pilot facility after more than 300 operating hours has been above 95% thanks to the ability and good performance of the ZincexTM technology (solvent extraction and electrowinning), in which obtaining of SHG electrolytic zinc is fully guaranteed with high current efficiency (above 93%) and good deposit morphology. In definitive, a profitable marriage between indirect bioleaching process and ZincexTM technology has been successfully demonstrated in TR facilities at pilot plant scale, and main results of such integrated pilot plant operation are presented in this paper.

O estudo dos sistemas de iluminação residencial é fundamental para os alunos do curso Técnico em Edificações. Geralmente as práticas de ensino adotadas nas escolas públicas são tradicionalistas, onde o aluno assume uma postura passiva em seu processo de aprendizagem. Este artigo avalia a contribuição de uma sequência didática sobre circuitos elétricos de iluminação residencial, acionados por interruptores simples, intermediários e paralelos no Curso Técnico Integrado em Edificações. O trabalho proposto foi concebido para que pudesse contribuir com o docente no processo de ensino, a fim de motivar no aluno a consciência, a motivação, a reflexão e o prazer pelo estudo. Para tanto, utilizouse ambientes virtuais de aprendizagem combinadas com o uso de componentes animados, além de aulas práticas laboratoriais. Os resultados demonstraram que o uso de sequências didáticas, quando bem planejadas, torna o processo de ensino-aprendizagem mais dinâmico, interativo e mais eficiente. Sequência Didática.

Generally the teaching practices adopted in public schools are traditionalist, where the student takes a passive stance in his learning process. This article evaluates the contribution of a didactic sequence on electrical circuits of residential lighting, activated by simple, intermediate and parallel switches in the Integrated Technical Course in Buildings. The proposed work was conceived so that it could contribute with the teacher in the teaching process, in order to motivate in the student the conscience, the motivation, the reflection and the pleasure for the study. For that, virtual learning environments were used combined with the use of animated components, in addition to practical laboratory classes. The results showed that the use of didactic sequences, when well planned, makes the teaching-learning process more dynamic, interactive and more efficient. Didactic Sequence. Electrical Circuits.
