Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
Hybridization effect on the mechanical properties of curaua/glass fiber composites
(2013-08-20)
The aim of this paper was to evaluate the effect of hybridizing glass and curaua fibers on the mechanical properties of their composites. These composites were produced by hot compression molding, with distinct overall ...
Olive Cellulosic Fibre Based Epoxy Composites: Thermal and Dynamic Mechanical Properties
(2022-01-01)
This study deals with the evaluation of the impact of three different olive tree residues: olive tree small branch (OTS), olive tree big brunch (OTB) and olive tree leaves (OTL) as a filler on thermal properties of olive/epoxy ...
Aspects of Mechanical Behavior and Modeling of a Tropical Unsaturated Soil
(2013-10-01)
The research studies the applicability of two elastoplastic models for the collapse prediction of the lateritic soil profile from Southeastern Brazil. These tropical soils have peculiar geotechnical behavior, due to their ...
Effect and mechanism of nanosize copper oxide on some physical and mechanical properties of flakeboards
(Universidad del Bío-Bío, 2011)
Thermal and mechanical properties of woodflour/tannin adhesive composites
(Wiley, 2004-01-05)
Composite materials formulated with a natural polyphenolic matrix (commercial tannin adhesive made from quebracho tannin extract), pine woodflour as reinforcing material, and hexamethylenetetramine as hardener were prepared ...
Study of Brazilian commercial Oriented Strand Board panels using stress wave
(2013-08-09)
Today lumber industry has shown a clearly evident trend towards wood based panels' production; and, among them, Oriented Strand Board (OSB) has become more and more prominent. Nondestructive Testing (NDT) such as stress ...
Discrete second order constrained Lagrangian systems: first results
(American Institute of Mathematical Sciences, 2013-12)
We briefly review the notion of second order constrained (continuous) system (SOCS) and then propose a discrete time counterpart of it, which we naturally call discrete second order constrained system (DSOCS). To illustrate ...
Kinetics and reaction mechanism of biothiols involved in SNAr reactions: an experimental study
(Frontiers Media, 2022)
Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles ...
