We roll dice representing road deaths to see if a plastic speed camera can bring down your score (it can – if you only point it at the highest rollers).
With a brush head that makes 40,000 pulsations a minute (hovering hummingbirds' wings beat 3,000 times during the same minute) and 7,600 simultaneous side-to-side oscillations, the $79.99 plastic speed stick is being positioned as the BMW of the bathroom.
Place on the plastic speed control dial knob.
Exposure to some estrogen mimics or antiandrogens can delay puberty in female rodents (Monosson et al. 1999), whereas experimental exposure to low doses of estrogenic bisphenol A, found in some plastics, speeds growth and puberty in rats (Howdeshell et al. 1999).
Pollution near the trapezium-shaped pedestrian crossings increased 55.7% and near the plastic circular speed bumps – 58.6%.
The plastic wave speed is derived from the linearized 1-D version of the widely used viscous plastic (VP) and elastic viscous plastic (EVP) sea-ice models.
(When degrading plastic, though, speed is a relative term). In the new study, it took 100 worms about 12 hours to eat their way through 92 milligrams of plastic, the mass of about three or four grains of rice.
At 6 a.m., the official start time, he was suddenly everywhere in his plastic clogs, speed-walking from the trawl nets to the winches, kneeling on the fiberglass deck of the Kristy Misty, which he built and named after his daughters, and finally lowering the skimmer nets, one on each side of the boat, into the water.
On a recent day, in a clothing factory in Antinea, a manufacturing town between Venice and Milan, hundreds of pairs of glitzy, highly beaded and sequined women's slacks, encased in plastic bags, sped along an overhead mechanized rack, routed by computer to niches on the second floor, each niche corresponding to an American department store.
A high efficiency optical coupler has been developed for high speed plastic optical fiber communication.
The importance of factors, such as material softening, plastic deformation, crack speed and viscosity, is identified by parametric studies.
