Chemical processes which occur during glass polishing are reviewed within the context of
current mechanical models for the polishing process. The central chemical process which …

… However, l-arginine lowers both oxide and nitride polish rates, while l-proline appears to
have an effect on nitride rate and not on oxide polish rate. Thus the blanket polish rate behavior …

From the outset multiple causes have been suggested for changes in melanic gene frequency
in the peppered moth Biston betularia and other industrial melanic moths. These have …

The evidence for change in frequency of the melanic carbonaria morph in the peppered moth
Biston betularia (L.) (Lepidoptera: Geometridae) in England and Wales is reviewed. At mid‐…

For years scientists turned to the CRC Handbook of Laser Science & Technology for reliable
data on optical materials. Out of print for several years, that standard-setting work now has a …

Bridge collapses and water main explosions focus national attention on the crumbling condition
of the nations infrastructure. Catastrophic infrastructure failures are always a momentary …

A new index of selection, α, is presented. It measures the degree to which a predator is more
likely to take one kind of prey rather than another, and thus provides a direct estimation of …

… CBA photometry began 2 days later, and the first night's observation (by L. Cook) showed a
4 hr signal in the light curve, which proved to be stable after a few days' coverage (Cook et al…

We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae
based on newly obtained data and past publications. In many systems, the evolution of the …

Colour variation in the peppered moth Biston betularia was long accepted to be under strong
natural selection. Melanics were believed to be fitter than pale morphs because of lower …
