Influence of stiffness related to the C40 strength class of the hardwood group established by the Brazilian standard in the design of timber structures
(2021-01-01)
The Brazilian standard ABNT 7190 (1997) establishes the strength classes C20, C30, C40 and C60 for the proper framework of the different wood types in the group of hardwoods. Associated with the strength class, which is ...

Embedment strength of dowels in wood specimens according to ABNT NBR 7190 (1997) and EUROCODE 5 (2004)
(Fundação Gorceix, 2017-03-01)
Abstract The study of connections for timber structures has been the subject of intense research in Brazil. This work aimed to study the embedment strength of connections made by steel pins (dowels) in specimens of reforested ...
Determination of solubility product of mercurous acetate at various ionic strengths in aqueous medium
(Editora Unesp, 1996-01-01)
The conditionals (K-ps) and thermodynamics (K-ps(o)) solubility products of mercurous acetate have been determined, in aqueous solution, at 25 degrees C and ionic strength (I) comprised between 0.300 and 3.000 mol/L (NaClO4). ...
