Variability of Water Uptake Studies of Biomedical Polymers
(WILEY-BLACKWELL, 2011)
Water uptake influences many properties of polymers and has been widely studied. In the context of polymeric biomaterials, several publications reported an unusual high variability of analytical results, without further ...
Multiscale analysis of water uptake and erosion in biodegradable polyarylates
(ELSEVIER SCI LTD, 2012)
The role of hydration in degradation and erosion of materials, especially biomaterials used in scaffolds and implants, was investigated by studying the distribution of water at length scales from 0.1 nm to 0.1 mm using ...
Brain stimulation and morphine reward deficits in dopamine D2 receptor-deficient mice
(Springer, 2005-10)
Rationale: The rewarding effects of lateral hypothalamic brain stimulation, various natural rewards, and several drugs of abuse are attenuated by D1 or D2 dopamine receptor (D1R or D2R) antagonists. Much of the evidence ...
Contribution of persistent Na+ current and muscarine-sensitive K+ current to perithreshold theta resonance in CA1 pyramidal neurons
(2015)
Most neurons from hippocampus and other learning- and memory-related
areas have the ability to intrinsically generate subthreshold rhythmic
activity at theta frequency (4-10 Hz), which may contribute to the strong
theta ...
Light-induced relaxing dipoles in n-type AlxGa1-xAs
(1995-01-01)
Thermally stimulated depolarization-current measurements with monochromatic light excitation are applied to AlxGa1-xAs. We obtain conclusive evidence that electric-dipole relaxation occurs in this alloy. Light-induced ...
Relaxational study of poly(2-chlorocyclohexyl methacrylate) by thermally stimulated current, dielectric, and dynamic mechanical spectroscopy
(AMER CHEMICAL SOC, 1999)
A comparative study of the mechanical and dielectric relaxation spectra of poly(2-chlorocyclohexyl methacrylate) (P2CCM) is reported. Two clear relaxational zones are found. The spectra present a moderate subglass gamma ...
Investigation of Ferroelectricity and Piezoelectricity in Polar and Non-polar Polymers
(2022-06-01)
An overview is presented of experimental investigations during two decades at the Polymer Group Prof. Bernhard Gross in Sao Carlos, Brazil, on the properties of piezoelectric polymers. The paper is focused on innovations ...
Transmitter release from cochlear hair cells is phase locked to cyclic stimuli of different intensities and frequencies
(Society for Neuroscience, 2012-11)
The auditory system processes time and intensity through separate brainstem pathways to derive spatial location as well as other salient features of sound. The independent coding of time and intensity begins in the cochlea, ...
