The research study discussed and amplified in this paper consisted
of the development and evaluation of two instructional concepts
illustrating the procedures for 1) typing an offset master, and 2) duplicating
offset copies. Each concept was prepared for use with the
Audiscan projector, which utilizes a 16mm continuous loop filmstrip...
Purpose of the Study:
The purpose of this research was to study the school districts
in Umatilla County as they existed in 1962-3 and to formulate a
guide for reorganization of these districts into sound efficient units.
The following sub-factors were considered essential to this research,
and were dealt with...
Studies were conducted on artificially infected susceptible and
resistant barley varieties in an attempt to determine the effect of
barley yellow dwarf virus on the growth and development of these
plants. A resistant and a susceptible variety were infected at four
stages of growth and harvested at two stages. Roots,...
A taxonomic investigation was made of 24 taxa belonging
to the section Trichodium (Michx.) Trin., of
Agrostis, and the genus Podagrostis. Experimental methods
were employed, including: uniform garden culture of transplants
and plants grown from seeds collected in natural
populations; breeding studies; physiological and phenological
investigations; cytological studies; ecological
studies...
The purpose of the study was to survey aspects of environmental
knowledge and beliefs among Grade 10 students in Australia, in the
belief that such information would be useful for workers in the developing
field of environmental education there.
A survey instrument prepared and used for a similar purpose in...

Aspects of hydromineral balance in the stenohaline fresh-water
catfish, Ictalurus nebulosus (Le Sueur) were studied at 10° and 20°C.
Temperature did not affect water content significantly. Water content
was 78 ml/100 g body weight, 32% of which is in muscle and 49% in
the skeleton and associated connective tissue. The...
In freshwater the crayfish, Pacifasticus leniusculus, maintains
sodium balance by absorbing sodium against a large concentration
gradient. The site of uptake is the gills. The rate of uptake is
regulated and can be increased by depleting the animals of sodium
Neither the mechanism of sodium transport or the regulatory mechanism...
