Biobased composites from tannin-phenolic polymers reinforced with coir fibers
(ELSEVIER SCIENCE BV, 2010)
Tannin-phenolic polymers prepared using tannin, a macromolecule obtained from natural sources, were used in the preparation of composites reinforced with coir fibers. The composites based on tannin-phenolic polymers (50% ...
Invariance of a Shift-Invariant Space in Several Variables
(Springer, 2011-12)
In this article we study invariance properties of shift-invariant spaces in higher dimensions. We state and prove several necessary and sufficient conditions for a shift-invariant space to be invariant under a given closed ...
Fixed points on Klein bottle fiber bundles over the circle
(Polish Acad Sciences Inst Mathematics, 2009-01-01)
The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S(1) for spaces which are fiber bundles over S(1) and the fiber is the Klein bottle K. We classify all such maps which can be ...
Fixed points on torus fiber bundles over the circle
(Polish Acad Sciences Inst Mathematics, 2004-01-01)
The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S-1 for spaces which axe fibrations over S-1 and the fiber is the torus T. For the case where the fiber is a surface with ...

Thermoset matrix reinforced with sisal fibers: Effect of the cure cycle on the properties of the biobased composite
(ELSEVIER SCI LTD, 2009)
Thermoset phenolic composites reinforced with sisal fibers were prepared to optimize the cure step. In the present study, processing parameters such as pressure, temperature, and time interval were varied to control the ...

Invariance of a shift-invariant space
(Birkhauser Boston Inc, 2010-01)
A shift-invariant space is a space of functions that is invariant under integer translations. Such spaces are often used as models for spaces of signals and images in mathematical and engineering applications. This paper ...
Analytical and experimental evaluation of the use of fibers as partial reinforcement in shotcrete for tunnels in Chile
(Elsevier, 2018-07)
This work evaluates experimentally the use of steel or polypropylene fibers in shotcrete as a partial replacement for the traditional reinforcement of electrowelded mesh used at the tunnel support for the subway in Santiago ...
