Sand dunes are found along the coasts of most of the large land
masses of the world. Because of their proximity to man and his
activities, the maritime sand dunes of Europe, particularly Germany,
France, Holland and Scandinavia, have the longest history of stabilization
activities and botanical investigation. There are...
There is need for more knowledge of the naturally acquired
diseases of the laboratory rat. Respiratory diseases occurring in
the species were reviewed with special reference to an acute respiratory
disease affecting certain rats in the Oregon State University
closed Wistar rat colony which has also involved human infections.
The...
The dairy industry relies primarily on consistent acid production
by the lactic streptococci for the manufacture of certain cheeses
and fermented dairy products. Variation in these cultures due to
genetic exchange has not been thoroughly investigated. This study
was undertaken to determine if genetic homology exists within the lactic
group,...
Gamma-gamma directional correlations were measured
in Ba¹³⁴ at ten angles between 90 degrees and 180 degrees in ten
degree increments using a scintillation spectrometer. The spectrometer
which used NaI crystals, differential energy selection,
and standard coincidence techniques was tested by measuring the
directional correlation of the two cascade gamma rays...
The investigations were based on a complete diallel cross
among three inbred lines of Suffolk sheep. Line of sire effects were
assumed to be an estimate of general combining ability effects while
sire x dam interaction was assumed to be an estimate of specific
combining ability. The line of dam...
