متن کاملShaking Compact Sets
If C is a compact subset of R and H is a halfspace bounded by a hyperplane π, the set C̃ obtained by shaking C on π is defined as the set contained in H, such that for every line ` orthogonal to π, C̃ ∩ ` is a segment of the same length as C ∩ `, and one of its endpoints is on π. It is shown that there exist d + 1 hyperplanes such that every compact set can be reduced to a simplex, via repeated s...
متن کاملHead-shaking nystagmus
Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...
متن کاملA laboratory shaking machine.
Thermoviridin appeared to be an organic acid which was dialyzable. The antibiotic showed maximum absorption in the range of 268 to 272 m,u. Thermoviridin was primarily active against the gram positive bacteria tested. A preliminary toxicity test in mice, consisting of a single intraperitoneal injection of 32 mg of material which had 25 thermoviridin units per mg, did not cause death in any case.

They, in turn, had mated with other modern humans, leaving their distant descendants—us—with a permanent Neandertal legacy....
