Abstract
Knowledge of walls and other structural elements construction characteristics and techniques is mandatory in the maintenance and restoration of historical buildings. Such information is obtained from documents or by comparing with monuments of the same period. Documents are difficult to obtain and comparison with other buildings can be inaccurate. The use of direct invasive techniques may be considered but they are likely to damage structures or compromise buildings stability. Thus, indirect high-resolution methods are adapted to these investigations. This work describes a GPR and a Seismic Transmission Tomography survey to investigate the walls and columns of the 14th century Batalha Abbey (UNESCO heritage site). High-resolution GRP data revealed the dimensions and thicknesses of different walls and the structure and nature of materials inside them. The Seismic Transmission Tomography survey, supported by high-resolution photogrammetry scanning for accurate positioning of sources and geophones, was carried out to investigate the Abbey columns. Seismic velocities distribution inside the columns characterized their interior and clarified the nature of the materials used. Columns construction followed the same technique and used the same materials. However, each column depicts a different velocity zonation that could correspond to different stages of deterioration for each one.

Abstract
This paper develops a sustainable approach in the productive context associated with the fish industry. The supply network design problem is addressed by using mathematical programming in order to avail the best configuration for the productive system. In this study, some environmental constraints for each echelon have been presented. Two mathematical models are proposed: cost and profit model. The models are validated with actual data obtained from a Colombian fish industry. The obtained results indicate an improved performance of the new supply network design by considering the sustainability approach derived from sustainable supply chain management (SSCM).

Abstract
Internationalization is a broad concept encompassing multiple facets. Higher Education Institutions (HEI) collaborators are key actors of the internationalization process and outcomes, being essential for education managers to promote internationalization initiatives, namely among their teachers. Nevertheless, the literature indicates that the number of teachers involved in those initiatives is still modest. It is therefore of utmost importance to understand how teachers initiate and maintain mobility assignments, so that HEI can implement effective strategies to promote this facet of internationalization. In this paper, we explore the teacher mobility topic through the lens of the Theory of Reasoned Action and the Theory of Planned Behavior. These two theories have been widely used to explain how people initiate and maintain behaviors, and are particularly relevant to understand teacher mobility. The paper includes results from phenomenological interviews with teachers that had one or more mobility experience under the Erasmus programme. The narratives of the participants in the study evidence the importance of prior intentions, attitudes and subjective norms in the resolution to undertake international assignments. Self-efficacy was also shown as determinant in the decision process of first and subsequent mobility initiatives. This paper also provides cues on how HEI can facilitate and encourage mobility experiences amongst their teaching staff.

Abstract
Transthyretin Familial Amyloid Polyneuropathy (TTR-FAP) is a rare neurological disease caused by a genetic mutation with a variable presentation and consequent challenging diagnosis, complex follow-up and treatment. At this moment, this condition has no cure and treatment options are under development. One of the disease's implications is a definite and progressive motor impairment that from the early stages compromises walking ability and daily life activities. The detection of this impairment is key for the disease onset diagnosis. With the goal of improving diagnosis of the symptoms and patients' quality of life, the authors have assessed the gait characteristics of subjects suffering from this condition. This contribution shows the results of a preliminary study, using a non-intrusive, markerless vision-based gait analysis tool. To the best of our knowledge, the reported results constitute the first gait analysis data of TTR-FAP mutation carriers.
