The X-ray dose absorbed in soft tissue located near plane
bone interfaces and in parallel-slab bone cavities was measured
experimentally with a polyethylene-film dosimeter.
The dose absorbed in soft tissue adjacent to plane bone interfaces
was measured by placing a 12.7 micron film of polyethylene,
upon which were deposited graphite...
A comparison was made of the d.c. conductivity of KCI:Pb²⁺
and KCl:PbO single crystals at temperatures greater than 325°C.
The energy of activation was 0.72 ev for all crystals. Lead concentration
was determined by chemical, optical and electrical methods. The
half band width of the UV absorption band at 273...
To the chagrin of his American comrades, Washington Irving would spend much of his life in Europe as a writer and cross-cultural explorer, including a stay in the halls of the Alhambra. This experience led to the completion of Tales of the Alhambra (1832), a collection of sketches, anecdotes, and...
Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato
spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint,
initially observed in a research greenhouse (Corvallis, OR), included stunting and
downward curling of leaves accompanied by bronzing, and occasionally tip necrosis.
Young leaves appeared either symptomless, deformed, or...
Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...
Of the major players in the birth and growth of nuclear technology, France and the United States are two of the biggest. Their glaring differences in culture and political regimes, therefore, have resulted in two very different attitudes toward adoption and implementation of nuclear power. Through extensive literary research, cultural...
