The relationship between pea enation mosaic virus
(PEMV) and aging pea aphids was studied. Although this
research initially emphasized the relationship between the
decline in the rate of PEMV transmission and the 'concentration
of PEMV within pea aphids, aphid age was found to be
the principle factor influencing transmission. Enzymelinked...
The primary purpose of this research study was to determine whether
significant differences occurred in the amount of knowledge achieved as
a result of using Braille or compressed speech as learning modes.
Biographic/demographic characteristics such as present age, highest
educational level achieved, age at loss of vision, age at initial...
The kraft and kraft-anthraquinone pulping processes were used
for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures.
Anthraquinone was added to the pulping liquor at two levels, 0.1%
and 0.2% based on wood, to study its effect on pulp delignification
at the three temperatures. The fluorescent behaviors of kraft...
