The subfamily Aphrodinae is represented in the Nearctic Region by eight species contained in a single tribe, Aphrodini, and genus Aphrodes. The external and internal morphology, biology and ecology of the Nearctic members of the genus Aphrodes were investigated. Distributional evidence indicates that six of the eight species, belonging to...
Straw has many uses, as feed, roughage, animal bedding, but
these requirements are not sufficient to utilize the available production.
In areas where grasskseed is produced, post-harvest straw is
burned in the field to help prevent crop disease the following year.
This treatment is very wasteful in terms of straw...
Arthrobacter ATCC 25581, capable of subterminal oxidation
of n-hexadecane to 2-, 3-, and 4- alcoholic and ketonic products,
was examined for the ability of this methylene hydroxylase capability
to be induced and repressed, and for structural relationships influencing
methylene function oxidation.
Induction was best carried out by use of n-alkanes...
Sodium ligninsulfonate, a water soluble wide-range molecular
weight polymeric by-product of the paper pulping industry, is
added as waste effluent to water ways or burned, causing extreme
pollution. The polymer is highly resistant to biodegradation. Therefore,
modification of the structure to a more readily biodegradable
form would be desirable, to...

The purposes of the study were: (1) to provide a descriptive
analysis and historical record of the undergraduate OSU Fourth Cycle
Urban/Rural-Migrant Teacher Corps program; (2) to follow up former
OSU Fourth Cycle corps members to determine their employment status
and attitudes toward their educational experiences; and (3) to determine...
Annual ryegrass (Lolium multiflorum) a major grass seed crop
in the Willamette Valley, Oregon, is presently burned in the fields
after harvest, causing considerable air pollution and general wastage
of a material which could be used in the manufacture of economically
important products. The cellulosic component of straw is relatively...
The primary purpose of this study was to determine the work values of the emotionally disturbed adolescents and to compare these values with those indicated by adolescents
of the same age level from a regular public school. A secondary objective was to compare the work values of the age levels,...
