Transmission electron microscopy of ultrathin sections was used to measure mouse retinal capillary basement membrane thickness (BMT). BMT increases predictably with age from 50 +/- 9 nm at 6 weeks to 154 +/- 27 nm at 20 months, but is not affected by strain or sex. There is an effect of retinal site, however, with BMT increasing with the radial distance from the optic nerve, 41 +/- 4 nm (center...

BACKGROUND Both the material and geometry of a total knee arthroplasty (TKA) component influence the induced periprosthetic bone strain field. Strain, a measure of the local relative deformation in a structure, corresponds to the mechanical stimulus that governs bone remodeling and is therefore a useful in vitro biomechanical measure for assessing the response of bone to new implant designs and...

Background: assessment of psychopathy has gained much attention in the past few decades. The four-factor model of psychopathy has proved to be an efficient model for assessment of psychopathy in forensic and non-forensic samples. Several measures have been developed to capture the four-factor model. These four factors are labeled as interpersonal manipulation, criminal tendencies, erratic lifes...

Field observations of major earthquake fault zones show that shear deformation is often confined to principal slipping zones that may be of order 1–100 μmwide, located within a broader gouge layer of order 10–100 mm wide. This paper examines the possibility that the extreme strain localization observed may be due to the coupling of shear heating, thermal pressurization, and diffusion. In the ab...

Collection and conversion of widespread mechanical energy is one promising way to alleviate environmental pollution crisis. Piezoelectric materials can effectively realise this between electrical energies. Here, via near-field electrospinning, piezoelectric poly(vinylidene fluoride) microfibers were fabricated on flexible polyethylene terephthalate substrate. Bending measurement indicated that ...
