The purposes of this study were to (1) identify major problems
faced by the youth who, in transition from school to work, have resorted
to anti-social behavior and are now inmates of Deuel Vocational
Institution, (2) identify the behavioral patterns of youth having employment
problems that resulted in incarceration within...
The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...
This study was undertaken to increase knowledge of opal phytoliths
in plants and soils of Oregon, and thus encourage further use of
phytoliths in future pedologic investigations.
Content of plant opal in needles from ten common Oregon conifer
species ranged from 0.2 to 7.9%. Western larch (Larix occidentalis)
contained the...
Acquisition of divergent-productive thinking skills by using
elementary science materials constitutes the basic idea of this experiment.
The data collected was used to determine statistically if
the materials had a significant role in inducing such skills.
The Ss were fifth-grade students obtained from two public elementary
schools in Oregon. Those...
A complete taxonomic review of the Family Eviphididae was
made for the first time. The family was found to contain forty-nine
species and five genera. The genera included were: Eviphis
Berlese, Scarabaspis Womersley, Alliphis Halbert, Pelethiphis
Berlese, and Thinoseius Halbert.
The new species described were: Eviphis oregonensis from
Deschutes County,...
The organization of behavioral activities in time is important
to a bird's survival and reproduction. To be successful, either
proximately or ultimately, a bird must apportion its behavior in time
so that it may obtain sufficient energy for maintenance activities and
for such activities as migration and reproduction. The organization...
A need has existed for an in-depth structural analysis of penstock
bifurcations because they form an integral part of hydroelectric
power plants. Their geometrical complexity has prevented classical
structural analysis from providing an accurate and overall picture of
the stresses in the structure.
Digital computers and the development of finite...
The photolysis of the aqueous thymine system has been investigated
at 214 nm, 229 nm and 254 nm at room temperature. Products
of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5-
hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine.
These together with thymine loss, were determined quantitatively
under a variety of conditions....
A taxonomic study of the genus Trichopezizella Raitviir is
presented. T. nidulus var. nidulus, T. horridula, T. barbata, and
T. relicina var. relicina are fully described and figured. Three
provisional combinations are made: T. nidulus var. hystriculus, T.
nidulus var. setigera, and T. relicina var. macrospora. T. onocleae
and T....
Inclusion of substantial levels of raw-frozen Pacific hake
(Merluccius productus) in diets of ranch-raised mink (Mustela vison)
causes a large percentage of animals to develop an abnormal condition
termed "cotton fur" (CF), characterized by depressed body
weight, microcytic-hypochromic anemia and a failure of under-fur
pigmentation. Observations by several groups of...
