The equations which govern the motion of a rigid satellite in
an inverse-square force field exhibit a weak coupling between the
translation of, and the rotation about the center of mass. The effects
of this translational-rotational coupling on the equilibrium positions
in a circular orbit, and their stabilities are examined....
Histones are presumed to be of chromosomal origin and provide
both structural and functional elements for chromatin. In like
manner the ribosomal proteins are of ribosomal origin and have
analogous roles. Considerable controversy over their cellular roles
exists because of the inability to compare directly both groups of
proteins. In...
Purposes and Method of Study
The purpose of this study was to find out if tenth grade girls
were aware of the probability that a majority of them would work at
some time during their lives, and if they planned to prepare for this
possibility. A questionnaire was designed and...
The physiologic specialization of nine isolates of stripe rust
(Puccinia striiformis West.) collected in the Pacific Northwest
was determined. The separation of races was based on the differential
susceptibility of the following wheat varieties: Cappelle
Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de
Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...
Bdellovibrio bacteriovorus is a small parasitic bacterium present
in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative
bacteria, an important role in soil ecology has been suggested
for this organism. A study of effects of herbicides upon
Bdellovibrio might consequently be of considerable value.
In this study...
This paper describes a study of two-phase gas-liquid vertical
annular climbing film flow. Using a high speed Fastax movie camera,

microscopic point methods for determining botanical composition on
perennial ryegrass (Lolium perenne L.) - subclover (Trifolium
subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) -
subclover pasture mixtures throughout a grazing season.
Botanical composition was determined on a monthly basis from...
Colleges and universities must be continually seeking means to
improve their financial management. One improvement would be to
lessen the amount of monies the state-owned university reverts to
the state at the end of the fiscal year. Such reversion is caused by
numerous departments, each with financial autonomy, incurring
greater...
The primary purpose of this study was to replicate a study of
Abel and Sahinkaya which investigated the emergence of race and sex

is explored. A circuit adapting a sampling oscilloscope to a...
Earthworms are capable of osmotic and ionic regulation while
living in a dilute balanced salt solution. When transferred from soil
to pond-water (PW) their body weight increases by 15 percent due to
a net uptake of water.
This results in an initial dilution of the
coelomic fluid (CF).
Subsequently, Na...

times before and after dosage. The determinations measured the
inhibition of...
Six organoclay complexes have been studied in terms of their
selective adsorption from binary solutions of methanol and toluene.
Analyses are based on differential refractometry methods. The
isotherms were of the usual "S" type. The crossover points reveal
trends in the organophilic nature of the interlaminar surfaces in
these clay...

is consistent if Euclidean geometry is. Specifically, a
model of Peano's axioms [2] is defined in the space of
Euclidean geometry, where Hilberts axioms [3] are taken
to be the axioms of Euclidean geometry.

absorbed by all species of plants from a foliar application. Approximately
22% and 42% of the applied chemical was absorbed by...
It is generally recognized that biochemical information is of
great importance to microbial taxonomy. This is particularly true
in the case of catabolic behavior of microorganisms in utilizing
glucose and allied compounds. Once the pathways operating in a
species are identified, and the relative participation of these pathways
is determined,...

Pants have become a seemingly necessary part of the average
American woman's wardrobe and may be worn for nearly every occasion.
However, many women have indicated that when conventional
methods of construction were used for pants-making, the pants did
not conform to their expectation of good fit. Observation showed that...
