This work examines relative constructions in Portuguese varieties based on the principle that Portuguese has a set of relativization strategies that are recognized in typological linguistics as constructions that define related groups of languages. It is postulated that these different strategies, when employed by the same linguistic system, do not really constitute variants of the same syntactic variable, but they are the speaker’s actual choices facing the necessity to perform different social and discursive functions.

Construction techniques with ruler and the compasses, fundamental on Euclidean geometry, have been related to modern algebraic theories such as solving equations and extension of bodies from the works by Paolo Ruffini (1765-1822), Niels Henrik Abel (1802-1829) and Evariste Galois (1811-1832). This relation could provide an answer to some famous problems, from ancient Greece, such as doubling the cube, the trisection Angle, the Quadrature of the Circle and the construction of regular polygons, which remained unsolved for over two thousand years. Also important for our purposes are the notions of algebraic numbers, transcendental and the criteria for constructability, of those numbers. The objective of this study is to reconstruct relevant steps of geometric constructions with ruler (unmarked) and the compasses, from the elementary to the outcome buildings, in the nineteenth century, considering those mentioned problems.

This paper aims to analyze the so-called paratactic verbal constructions, or PVCs, in contemporary European Portuguese. The PVCs are built from the cohesion of two inflected verbs, V1 and V2, connected or not by the conjunction e (and), and only the second verb retains its full semantic content. Our analysis follows the grammaticalization and functional linguistics approaches. The process of grammaticalization of the PVCs allowed the verbs ir (go), chegar (arrive), pegar (take) and agarrar (grab), in specific contexts such as the PVCs, to undergo changes in their morphosyntactic and semantic features, what leads its categorial status and its function to change.

A presente invenção descreve um selante de fibrina, o qual compreende uma serinoprotease extraída a partir de veneno de serpente, um crioprecipitado rico em fibrinogênio extraído de bubalinos e o diluente cloreto de cálcio. A invenção ainda ensina o método de formação do selante, cujos componentes são providos separadamente e polimerizam-se in situ após mistura, bem como seu uso. O selante de fibrina descrito apresenta inúmeras aplicações médicas tópicas e não há o risco de transmitir doenças infecciosas.
