Exploration of male inmates in the Deuel Vocational Institution : a case study

O Criador:: McNelley, William J.
Abstract:: 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...

A geographical systems analysis of the commercial crawfish industry in south Louisiana

O Criador:: Gary, Don L
Abstract:: 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...

Distribution, form, and signigicance of plant opal in Oregon soils

O Criador:: Norgren, Joel A.
Abstract:: 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...

A study of the relationship between the elementary science study unit attribute games and problems and the development of divergent-productive thinking in selected elementary school children

O Criador:: Huntsberger, John Paul
Abstract:: 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 review of the family Eviphididae (Acarina: Mesostigmata)

O Criador:: Shoemake, Rodger Russell
Abstract:: 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,...

Behavioral patterns and their temporal organization in breeding American Avocets

O Criador:: Gibson, Flash
Abstract:: 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...

Structural analysis of symmetrical penstock bifurcations by the finite element method

O Criador:: Shugar, T. A.
Abstract:: 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...

A study of the photolysis of the aqueous thymine system at 214 nm, 229 nm and 254 nm

O Criador:: Satcher, Robert Lee
Abstract:: 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....

The genus Trichopezizella

O Criador:: Haines, John Haldor, 1938-
Abstract:: 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....

Involvement of formaldehyde in depressed iron absorption in mink and rats fed Pacific hake (Merluccius productus)

O Criador:: Costley, Gary Edward
Abstract:: 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...
