- 21st Century Challenges in Engineering and Technological learningPublication . Viegas, Clara; Marques, Arcelina; Alves, Gustavo R.The success of 21st century engineers1 depends on demanding challenges, involving a large scope of scientific and social competences. College education must help students to develop those competences in collaborative environments and better address these needs. Developing students’ knowledge and skills in contextualized engineering environments, practicing teamwork, leadership, decision-making, experimental work and critical thinking are some of the important aspects addressed in this track.
- A 360º overview of the VISIR remote laboratory in a handbookPublication . García-Zubía, Javier; Hernandez-Jayo, Unai; Alves, GustavoThe Virtual Instrument Systems In Reality (VISIR) remote laboratory was considered the best remote laboratory in the world, by the Global Online Laboratory Consortium (GOLC), in 2015. The first operational version of the VISIR remote laboratory was deployed in 2001. It was designed by Ingvar Gus tavsson, with the collaboration of Kristian Nilsson and Johan Zackrisson. Since then, VISIR has been deployed 21 times, in 19 universities, in 14 countries, on five continents. Because of it, there is a very powerful user community that serves thousands of students and is articulated around the VISIR Special Interest Group (SIG) and the VISIR Federation. However, this community of users does not have a unique document that integrates all the knowledge created and needed by the group. This paper describes the first handbook fully dedicated to the VISIR re mote laboratory, aimed at closing that gap.
- ABCC Subfamily Vacuolar Transporters are Involved in Pb (Lead) Detoxification in Saccharomyces cerevisiaePublication . Sousa, Cátia A.; Hanselaer, Simon; Soares, Eduardo V.The present work has as objective to contribute for the elucidation of the mechanism associated with Pb detoxification, using the yeast Saccharomyces cerevisiae as a model organism. The deletion of GTT1 or GTT2 genes, coding for functional glutathione transferases (GST) enzymes in S. cerevisiae, caused an increased susceptibility to high Pb concentrations (500-1000 μmol L(-1)). These results suggest that the formation of glutathione-Pb conjugate (GS-Pb), dependent of GSTs, is important in Pb detoxification. The involvement of ATP-binding cassette (ABC) vacuolar transporters, belonging to class C subfamily (ABCC) in vacuolar compartmentalization of Pb, was evaluated. For this purpose, mutant strains disrupted in YCF1, VMR1, YBT1 or BPT 1 genes were used. All mutants tested, without vacuolar ABCC transporters, presented an increased sensitivity to 500-1000 μmol L(-1) Pb comparative to wild-type strain. Taken together, the obtained results suggest that Pb detoxification, by vacuolar compartmentalization, can occur as a result of the concerted action of GSTs and vacuolar ABCC transporters. Pb is conjugated with glutathione, catalysed by glutathione transferases and followed to the transport of GS-Pb conjugate to the vacuole by ABCC transporters.
- ABHA - Advanced Biomechanical Hand AssistantPublication . Correia, Vasco; Alves, Lucas; Guimarães, Pedro; Vieira, Diogo; Oliveira, Diego; Marques, Arcelina; Lima, RafaelThe outlook for the future of physiotherapy is very promising, with a gradual increase in its demand. This trend is mainly explained by the fact that there is an increasingly active and ageing population in developed countries. The growing demand for this area will consequently lead to the need for many resources, both human and economic. Currently, there are several bionic hands with various uses and functions, and most of these hands are programmed to respond to the movements of a particular user. Besides, most of the applications of medical robotics are mainly directed to the area of surgery. With this proposal, we intend to simplify the whole physiotherapy or rehabilitation process. For that, we have developed an equipment capable of helping the patient to perform the exercises in the comfort of his home, but in an equally efficient way. The operation of the system consists of autonomous use by the patient, who must wear the glove and replicate the exercises, predefined for each user, performed by the biomechanical hand. Having the possibility to define the exercises, ABHA is transferable and can be used by more than one patient.

Garcia-Zúbia, Javier; Henandez-Jayo, Unai; Gustavsson, Ingvar; Alves, Gustavo R.The effectiveness of VISIR is compared to other experimentation activities under the point of view presented by the professor Soysal in 2000. Advantages and limitations are discussed in terms of equipment availability, infrastructure cost, and contribution to various elements of experimental learning.
- Acerca de la eficacia de VISIR como recurso en temas de electrónica circuital en ArgentinaPublication . Marchisio, Susana; Lerro, Federico; Merendino, Claudio; Plano, Miguel; Concari, Sonia B.; Arguedas, Carlos; García-Zubía, Javier; Hernández-Jayo, Unai; Alves, Gustavo R.“Virtual Instruments System in Reality” (VISIR) es una plataforma laboratorio de acceso remoto desarrollada en el Departamento de Ingeniería Electrónica del Instituto de Tecnología de Blekinge (BTH), Suecia. VISIR ha sido empleada y evaluada en varios países e instituciones en el mundo, reportándose en la bibliografía que la misma facilita el logro de resultados de aprendizaje en temas de electrónica analógica. El primer uso intensivo de VISIR por estudiantes en la Facultad de Ciencias Exactas, Ingeniería y Agrimensura (FCEIA), Universidad Nacional de Rosario (UNR) data de 2016. Dicha experiencia se llevó a cabo en la forma de caso de estudio en una asignatura de Ingeniería Electrónica (IE) que constituye el primer acercamiento a la electrónica de dispositivos y circuitos. El empleo de VISIR en el contexto curricular se propuso en forma complementaria al laboratorio tradicional, para la realización de una actividad de integración cuya solución requería del cálculo matemático y de la experimentación remota. Finalizada la experiencia se recabaron datos cuantitativos y cualitativos con el objetivo de evaluar la misma. En este trabajo se informan resultados que focalizan en la valoración por estudiantes y docentes de la eficacia de VISIR como recurso de aprendizaje en temas introductorios de la electrónica circuital.
- Acid pretreatment of sugarcane biomass to obtain hemicellulosic hydrolisate rich in fermentable sugarPublication . Morais Júnior, Wilson Galvão; Pacheco, Thályta F.; Corrêa, Priscila S.; Martins, António A.; Mata, Teresa M.; Caetano, NídiaThe objective of this work was to find the ideal pretreatment conditions with high efficiency to obtain a hydrolyzate rich in fermentable sugars and low possible inhibitors levels. Thus, it was applied diluted phosphoric acid to pretreat the sugarcane biomass. Through a Central Composite Design, it was evaluated the influence of temperature, operating time and acid concentration. The pretreatment efficiency was verified by the concentration of total monosaccharides in the liquid fraction after the reaction. The phosphoric acid concentration of 4.95% at 80 °C, during 375 min, resulted in a hemicellulosic hydrolyzate with the highest concentration of fermentable sugars (saccharification greater than 99%), with the absence of HMF and furfural, and relatively low amounts of acetic acid.

En esta ponencia pretendemos presentar el caso de una intervención realizada en una institución de Enseñanza Superior en el área de la ingeniería.
- Acoustic Emission Studies in Hip Arthroplasty – Peak Stress Impact In Vitro Cemented ProsthesisPublication . Gueiral, Nuno; Nogueira, ElisabeteEngineering has a very important role in the development of non-destructive monitoring of orthopaedical systems allowing the evaluation of its integrity. Sir John Charnley revolutionized the field of joint arthroplasty in the 1960s with the development of the total hip replacement. He replaced the diseased hip joint with a steel femoral component and a plastic acetabular socket cup combination, both fixed into the bone using a self-curing acrylic cement, polymethylmethacrylate (PMMA) (Browne et al, 2005). That way, he has restored some of the most problematic joints in the human body. The placement of the metal implant in the channel open in the femoral bone without using cement or by mechanical attack, called a non cemented arthroplasty, came into use in an effort to solve the problem.
