Thermally-responsive biopolyurethanes from a biobased diisocyanate
(Elsevier, 2015-09)
In this work, segmented biopolyurethanes with thermally-activated shape-memory properties were synthesized and characterized. All the employed starting materials were derived from renewable sources. The macrodiol, which ...
Time Trends in Serum Organochlorine Pesticides and Polychlorinated Biphenyls in the General Population of Biscay, Spain
(Springer, 2015-01)
Despite the measures adopted, levels of organochlorine compounds (OCs) are still being detected in the human body. This study aimed to explore factors related to changes in the concentrations of polychlorinated biphenyls ...
Photoactive self-cleaning polymer coatings by TiO2 nanoparticle Pickering miniemulsion polymerization
(2015-06-23)
Titanium dioxide Pickering stabilized methyl methacrylate/n-butyl acrylate (MMA/BA) copolymer latexes were synthesized by miniemulsion polymerization. The particle size of the hybrid latexes was controlled by the concentration ...
Selective placement of magnetic Fe3O4 nanoparticles into the lamellar nanostructure of PS-b-PMMA diblock copolymer
(Elsevier, 2015-04-27)
The aim of this work is to obtain a good and selective dispersion of Fe3O4 magnetic nanoparticles into the lamellar morphology of PS-b-PMMA diblock copolymer. The addition of unmodified nanoparticles inhibited the formation ...
Down-regulation of BDNF in cell and animal models increases striatal-enriched protein tyrosine phosphatase 61 (STEP61) levels
(Wiley, 2015-08-28)
Brain-derived neurotrophic factor (BDNF) regulates synaptic strengthening and memory consolidation, and altered BDNF expression is implicated in a number of neuropsychiatric and neurodegenerative disorders. BDNF potentiates ...
Simultaneous catalytic de-polymerization and hydrodeoxygenation of lignin in water/formic acid media with Rh/Al2O3, Ru/Al2O3 and Pd/Al2O3 as bifunctional catalysts
(Elsevier, 2015-04-28)
[EN] The catalytic solvolysis of 3 lignins of different sources in a formic acid/water media using bifunctional Ru/Al2O3, Rh/Al2O3, Pd/Al2O3 catalysts was explored in a batch set-up at different temperatures and reaction ...
Gas analyzer's drift leads to systematic error in maximal oxygen uptake and maximal respiratory exchange ratio determination
(Frontiers Media, 2015-10)
The aim was to examine the drift in the measurements of fractional concentration of oxygen (FO2) and carbon dioxide (FCO2) of a Nafion-using metabolic cart during incremental maximal exercise in 18 young and 12 elderly ...
Analysis of DC–DC power supply systems for pulsed loads from green electronics perspective
(The Institution of Engineering and Technology, 2015-06-01)
Discontinuous loads frequently compromise the performance of their power source and electronics. They cause the voltage and current ripple at the source and load, and introduce electromagnetic interferences. Also, they ...
Heart Rate-Based Prediction of Fixed Blood Lactate Thresholds in Professional Team-Sport Players
(Lippincott, Williams & Wilkins, 2015)
The aim of this study was to investigate whether the speed associated with 90% of maximal heart rate (S90%HRmax) could predict speeds at fixed blood lactate concentrations of 3 mmol·L−1 (S3mM) and 4 mmol·L−1 (S4mM). ...
Estimation of the Maximal Lactate Steady State in Junior Soccer Players
(Thieme, 2015-09-02)
This study aimed to predict the velocity corresponding to the maximal lactate steady state (MLSS(V)) from non-invasive variables obtained during an incremental maximal running test (University of Montreal Track Test, UMTT) ...
