Abelianized obstruction for fixed points of fiber-preserving maps of surface bundles
(Juliusz Schauder Ctr Nonlinear Studies, 2009-06-01)
Let f: M -> M be a fiber-preserving map where S -> M -> B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...
Mechanical properties of polypropylene composites based on natural fibers subjected to multiple extrusion cycles
(John Wiley & Sons Inc, 2007-01)
The influence of multiple extrusion cycles on the behavior of natural fibers-reinforced polypropylene was studied. Composites were fabricated with 20 wt % of flax fibers. Final fibers dimensions (length and diameter) were ...
Starch–Cellulose Fiber Composites
(Wiley, 2008)
The aim of this review is to show the relationships between the structure, processing and properties of the composite material based on cellulose or lignocellulose fibres and starch based matrix. Properties of blend based ...
A Morphological View of the Sodium 4,4 `-Distyrylbiphenyl Sulfonate Fluorescent Brightness Distribution on Regenerated Cellulose Fibers
(JOHN WILEY & SONS INC, 2010)
Evidence of the sorption of the whitening agent sodium 4,4`-distyrylbiphenyl sulfonate in the presence of the anionic surfactant sodium dodecylsulfate or the cationic surfactant dodecyl trimethyl ammonium chloride on ...
Cracking Control in Mezzanine Floor Slabs using Rice Husk Ash and Polypropylene Fibers
(Institute of Physics Publishing, 2020-02-28)
The continuous population increase in recent years requires a greater number of households to be built quickly, with good materials and produced under quality standards that guarantee their manufacturing process. The ...
Mechanical behavior direct shear a volcanic sand reinforced with polypropylene fiber and cement
(Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
This article describes consolidated Direct Cut tests not drained in the laboratory, carried out on samples of volcanic sand from Arequipa, Peru. The samples were tested for maximum dry density and optimal moisture content; ...
Fractal dimension in the evaluation of different treatments of muscular injury in rats
(2018-10-01)
Objectives: To evaluate alterations from different therapies in muscular injury using the Fractal Dimension (FD) method. Methods: 35 animals were allocated in Control Group (C), Injury Control Group (IC), Injury Low Level ...

High-dimensional decoy-state quantum key distribution over multicore telecommunication fibers
(2017)
Multiplexing is a strategy to augment the transmission capacity of a communication system. It consists of combining multiple signals over the same data channel and it has been very successful in classical communications. ...
