Collaborative learning in the office management studies field: a COIL experienc...
Ribeiro, S.; Calvão, A.R.; Barradas, E.; Andrade, E.The internationalisation of Higher Education Institutions (HEI) can occur across borders and at home. In recent years, the option for virtual mobility or collaborative online international learning (COIL) has been gaining special relevance. COIL "encompasses projects based on the involvement of teachers and students with different geographical, language and cultural backgrounds, for the development of collabora...
Industrial Automation Self-Learning Through the Develoment of Didactic Industri...
Cordeiro, A.; Abraços, M.; Monteiro, L.; Andrade, E.; Foito, Daniel José MedronhoTeaching industrial automation is a complex mission. The classical approach is based on lectures and laboratories assisted by teachers. Nevertheless, teaching industrial automation using the classical approach is not easy because this multidisciplinary area requires knowledge in control, energy, electronics, robotics and computer engineering, among others. In this way, this paper presents an approach to teach I...
Some new considerations about double nested graphs
Andelic, M.; Andrade, E.; Cardoso, D. M.; Fonseca, C. M. da; Simic, S. K.; Tosic, D. V.In the set of all connected graphs with fixed order and size, the graphs with maximal index are nested split graphs, also called threshold graphs. It was recently (and independently) observed in [F.K.Bell, D. Cvetkovi´c, P. Rowlinson, S.K. Simi´c, Graphs for which the largest eigenvalue is minimal, II, Linear Algebra Appl. 429 (2008)] and [A. Bhattacharya, S. Friedland, U.N. Peled, On the first eigenvalue of bi...
On the Faria's inequality for the Laplacian and signless Laplacian spectra: a u...
Andrade, E.; Cardoso, Domingos M.; Pastén, G.; Rojo, O.Let p(G)p(G) and q(G)q(G) be the number of pendant vertices and quasi-pendant vertices of a simple undirected graph G, respectively. Let m_L±(G)(1) be the multiplicity of 1 as eigenvalue of a matrix which can be either the Laplacian or the signless Laplacian of a graph G. A result due to I. Faria states that mL±(G)(1) is bounded below by p(G)−q(G). Let r(G) be the number of internal vertices of G. If r(G)=q(G),...
Group B Streptococcus Hijacks the Host Plasminogen System to Promote Brain Endo...
Magalhães, V.; Andrade, E.; Alves, J.; Ribeiro, A:; Kim, K.; Lima, M.; Trieu-Cuot, P.; Ferreira, P.Group B Streptococcus (GBS) is the leading cause of meningitis in neonates. We have previously shown that plasminogen, once recruited to the GBS cell surface and converted into plasmin by host-derived activators, leads to an enhancement of bacterial virulence. Here, we investigated whether plasmin(ogen) bound at the GBS surface contributes to blood-brain barrier penetration and invasion of the central nervous s...

This Study presents: I - The two steps genesis of the synthetic maize population Fandango, A) NUTICA creation: in 1975, Miguel Mota and Silas Pego, initiated a new type of polycross method involving 77 yellow elite inbred line...
