Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate
(cycloate)¹ is essential for satisfactory weed control with injection
type incorporation in sugar beet (Beta vulgaris Linn.) production.
Previous field experience with injection incorporation has indicated
that sufficient lateral diffusion for satisfactory weed control has not
occurred under all field conditions. Researchers who have been...
Previous research has shown that specific carotenoid pigments
function through oxidation-reduction reactions to protect chlorophyll
from photooxidation in the presence of reduced nicotinamide adenine
dinucleotide phosphate (NADP). The hypothesis that diuron (3-(3, 4-
d chloropheny1)-1, 1-dimethylurea) initiates phytotoxicity by inhibition
of NADPH synthesis was examined. All experiments were conducted

machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...
Purpose of the Study:
The purpose of this study was to identify and compare the current
written philosophical expressions of industrial arts with the
acceptance of these by select groups of industrial arts teacher educators.
The data for this study were obtained through the use of a
The depression of the 1930s had an early effect on the state of Oregon. A
decline in timber and agricultural production resulted in severe unemployment in the
late 1920s. State and local charitable organizations attempted to care for the
unemployed but they did not have the financial resources to do...
This study traces British government policies with regard to Palestine from the time the British Expeditionary Forces under General Allenby invested Jerusalem in December 1917 to the imposition of the Mandate with Britain as the Mandatory power, which came into effect on July 22, 1922. The first chapter provides an...
An ionization chamber was constructed, using a fiberglass wall
sphere, for the purpose of measuring background radiation. The
system consists of the fiberglass wall chamber, 38.85 liters in
volume, air filled, not sealed, used in conjunction with a precision
capacitor, nulling voltage supply and electrometer. It was calibrated
