Eleven small Mesozoic plutons crop out within a 76-squaremile
area of the southern Seven Devils Mountains in west-central
Idaho. The plutons are divided into a mafic suite, an older granitic
suite, and a younger granitic suite on the basis of age, lithology, and
degree of metamorphism.
The six plutons of...
This paper records a study of two quadratic number fields. In the first field, denoted by Ra[[square root] 11], the unique factorization theorem holds. In the second field, denoted by Ra[[square root] 10], it is demonstrated that the unique factorization theorem does not hold and therefore ideals are introduced to...
Penetration has long been recognized as an important factor
in the action of chemicals on plants. The effectiveness of herbicides
on such plants as blackberries is often thought to be limited by the
failure to obtain adequate penetration through the cuticular barrier.
A number of factors, among them relative humidity,...
The energy absorbed by microscopic volumes exposed to ionizing
radiation is not well represented by the average dose due to the small
number of discrete energy transfers involved. The energy deposited in
a microscopic volume can be determined by measuring the ionization in
a detector filled with gas at low...
A computer program was developed for analyzing culverts
under earth embankments constructed of compacted cohesive soil
using the finite element method. The culvert-embankment system
is represented as a two-dimensional plane strain problem. The
plane of investigation is taken normal to the culvert axis. The soil-culvert
interface is assumed to be...
