Effects of fatigue on muscle stiffness and intermittent sprinting during cycling
(Lippincott Williams & Wilkins, 2011)
Purpose: It was recently demonstrated that musculoarticular (MA) stiffness is related to sprint cycling performance in nonfatigued conditions. This study examined whether relatively stiffer cyclists were more effective at ...
Effect of the sampling rate on the assessment of flicker severity due to phase jumps
(IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ...
Efficacy of management policies on protection and recovery of natural ecosystems in the Urdaibai Biosphere Reserve
(Natural Areas Association, 2011-10-01)
Knowledge of landscape patterns and dynamics is essential for land use planners and natural resources managers. They need to know how landscapes have changed in order to determine the consequences and efficacy of the ...
Calculation of positron characteristics for elements of the periodic table
(IOP Publishing Ltd, 2011-01-10)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the
periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the
electronic ...
Generation of Reactive Oxygen Species (ROS) is a key factor for stimulation of macrophage proliferation by ceramide 1-phosphate
(Elsevier, 2011-12-06)
We previously demonstrated that ceramide 1-phosphate (C1P) is mitogenic for fibroblasts and macrophages. However, the mechanisms involved in this action were only partially described. Here, we demonstrate that C1P stimulates ...
Illusions of causality at the heart of pseudoscience
(Wiley on behalf of the BPS, 2011-03-16)
Pseudoscience, superstitions, and quackery are serious problems that threaten public health and in which many variables are involved. Psychology, however, has much to say about them, as it is the illusory perceptions of ...
Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
(IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
Reversible optical storage properties of nanostructured epoxy-based thermosets modified with azobenzene units
(ACS, 2011-11-22)
Azo-containing polymers are of particular interest in the design of materials for applications in optical recording. The aim of this contribution was the synthesis and characterization of optically active epoxy-based ...
Nanostructuration of self-assembled poly(styrene-b-isoprene-b-styrene) block copolymer thin films in a highly oriented pyrolytic graphite substrate
(Elsevier, 2011-01-03)
Highly oriented pyrolitic graphite (HOPG) is a useful substrate to visualize epitaxial formation due to its crystallographic structure. The morphology of a poly(styrene-b-isoprene-b-styrene) block copolymer thin film on a ...
