Temperature and water potential effects on the growth,
transpiration, total nonstructural carbohydrate (TNC) content, and
nutrient uptake of sudangrass (Sorghum vulgare var. piper) were
investigated in laboratory experiments. The effect of...

Laboratory experiments were conducted to study those factors which
control the rate at which salts, such as magnesium chloride and sodium
chloride, are removed from titanium sponge. The sponge was prepared by
reducing titanium tetrachloride with...

Five newly released and two Eastern European winter wheat
cultivars were grown under five different seeding rates (80, 160,
240, 320, 400 seeds per m²). Four of these newly released cultivars
were grown at three different locations which have...

Extractable forms of Al and Fe were studied in five soils from
the Coast Range, and in two soils from the Willamette Valley in
Oregon.
Exchangeable Al was determined in a way which permitted a
comparison of three different methods for its...

The photochemical reaction between O⁻ ions and F centers
was investigated. The activation energy was determined by the
Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K.
The diffusion of alpha centers towards the oxide ion was...

Cultural and developmental characteristics of a collection of
Anthracobia melaloma with a brown hymenium and a barred exterior
appearance were examined. It grows well in culture on CM and
CMMY agar media and has a growth rate of 17 mm in 18 hours....

A method for measuring the spark-shower radiance of metals
when abraded on an abrasive grinding wheel was developed for
evaluating their sparking tendency. One hundred metals were tested
and rated relative to commercially pure iron. The radiance...

The need for classifying vegetation in a more precise way is
evident. Also, there is a need to provide a hierarchical classification
scheme that will match changes in image characteristics as one
moves through the scales from space to conventional...
