Efficient photocatalytic reactors via 3D printing: SLA fabrication and TiO2 hyb...

Barbosa, ISO; Manrique, Y.A.; Paiva, D.; Faria, JL; Santos, RJ; Silva, CG

Additive Manufacturing (AM) was evaluated as a promising technology for constructing photocatalytic reactors due to its inherent ability to produce complex geometries with high precision and customization. In this work, a 3D structure was designed to achieve a good light distribution inside a cylindrical batch reactor and printed using the stereolithography (SLA) technique. A hybrid material composed of a comme...

The 2020 IDS release of the Antwerp COR*-database. Evaluation, development and ...

Jenkinson, S.; Anguita, F.; Paiva, D.; Matsuo, H.; Matthijs, K.

The Antwerp COR*-IDS database 2020 is a transformed and harmonized historical demographic database in a cross-nationally comparable format designed to be open and easy to use for international researchers. The database is constructed from the 2010 release of the Antwerp COR*-historical demographic database, which was created using a letter sample of the whole district of Antwerp (Flanders, Belgium). It has a to...

Linking the historical sample of the Netherlands with the USA censuses, 1850– 1940

Paiva, D.; Anguita, F.; Mandemakers, K.

During the 19th and early 20th century about 220,000 Dutch born persons migrated to the USA. The Historical Sample of the Netherlands (HSN) contains about 85,500 persons born in the Netherlands between 1812 and 1922. In this article we report the way we have matched persons from the HSN with the American censuses from the period 1850 till 1940. For this purpose, a linking process was designed, comprising of thr...

Collapsed rhythms: the impact of urban change in the everyday life of elders

Paiva, D.

This article discusses the impact of urban change in everyday life rhythms. Recently, urban space has been described and analyzed as polyrhythmic, being a congregation of diverse movements by different agents. While the role of materiality in this dynamic is recognized, the impact of urban change in everyday life rhythms is still underexplored. Seeing urban rhythms as comprised by affective relationships, I ana...


Canine mastocytosis

Paiva, D.; Mendonça, A.; Vala, Helena

Mastocytosis is a mast cell disorder in which its exaggerated proliferation can occur in two forms: systemic and cutaneous (Davis et al., 1992). Because canine mastocytosis is a rare situation of controversial and difficult diagnosis, the goal of this study consists in a current revision of this subject, in order to sensitize the veterinary staff to its severity, with particular focus on the information the vet...


Characterization of the apoptotic index in canine mastocytomas.

Paiva, D.; Cruz, R.; Mega, A.; Vala, Helena

Introdution: Studies on apoptosis have been described in several neoplasias. Apoptosis is a biological process of programmed cell death that, due to its important role in oncogenesis, may elucidate some aspects. Objective: Detection of apoptosis in canine mastocytoma to determine its relationship with histologic grading, apoptotic index and prognosis. Material and methods: 12 cases of canine mastocytoma, from t...
