A polarographic oxygen electrode was used to measure the oxygen transmissibility of seven contact lenses of varying water content and center thickness. A similar electrode was used to measure the oxygen uptake following wear of these same contact lenses for both the open- and closed-eyelid conditions on five young healthy subjects. Linear regression revealed a strong correlation between oxygen ...

Seats have been newly developed with an anti-vibration suspension system for agricultural machinery. These seats were examined in a series of laboratory tests to determine their static and dynamic physical characteristics. These seats are specifically designed for the Japanese physique. An artificial track was constructed to simulate a farm field based on BSI (British Standard) and to examine v...

BACKGROUND Influenza super-strains can emerge through recombination of strains from birds, pigs, and humans. However, once a new recombinant strain emerges, it is not clear whether the strain is capable of sustaining an outbreak. In certain cases, such strains have caused major influenza pandemics. METHODS Here we develop a multi-host (i.e., birds, pigs, and humans) and multi-strain model of ...

The potential rapid availability of large-scale clinical episode data during the next influenza pandemic suggests an opportunity for increasing the speed with which novel respiratory pathogens can be characterized. Key intervention decisions will be determined by both the transmissibility of the novel strain (measured by the basic reproductive number R0) and its individual-level severity. The 2...

This study investigates the vibration power flow behavior and performance of inerter-based isolators mounted on finite infinite flexible beam structures. Two configurations with spring, damper, inerter as well different rigidities foundation structures are considered. Both time-averaged transmission force transmissibility studied used indices to evaluate isolation performance. Comparisons made ...

Abstract To achieve better anti-vibration performance in a low frequency region and expand the range of vibration isolation, bilateral supported bio-inspired (BBAV) structure composed purely linear elements is proposed, inspired by motion form bird legs nonlinear extension compression muscles tendons. The kinematic relations dynamic model considering vertical rotational vibrations are establish...
