A comparison of watershed contamination between a sewered and an unsewered community

Creator:: Maritim, Gabriel Kipngeno, 1950-
Abstract:: In 1968, a study conducted by the sanitarians of the State Health Division and Benton County Health Department revealed a high failure rate of on-site sewage disposal systems in Southwest Corvallis. The survey team concluded that sewage disposal in this area was inadequate, and a significant health hazard existed due...

A comparison of the prevalence of infectious gastrointestinal disease and the quality of individual, surface source water systems in Lincoln County, Oregon

Creator:: Nauman, Hal Eugene
Abstract:: This study was a comparison of the prevalence of infectious gastrointestinal disease and the quality of construction of individual, surface source water systems in Lincoln County, Oregon. Two measurement instruments were developed for this study. An objective instrument was developed to determine if the water systems observed in the study...

An Interdisciplinary Assessment of Current Pesticide Management Practices in the Caribbean Region

Creator:: Gray, Nancy L.
Abstract:: This study examined the existence and effectiveness of current pesticide management programs in the Caribbean region. A questionnaire was developed to assess the current pesticide managment programs in the Caribbean region and to determine the strengths and weaknesses of the existing education and training programs, governmental policies, and other resources....

Plutonic rocks of the southern Seven Devils Mountains, Idaho

Creator:: White, Willis Harkness
Abstract:: Eleven small Mesozoic plutons crop out within a 76-squaremile area of the southern Seven Devils Mountains in west-central Idaho. The plutons are divided into a mafic suite, an older granitic suite, and a younger granitic suite on the basis of age, lithology, and degree of metamorphism. The six plutons of...

The quadratic integral domains Ra[[square root] -11] and Ra[[square root] 10]

Creator:: Miller, William Eugene
Abstract:: This paper records a study of two quadratic number fields. In the first field, denoted by Ra[[square root] 11], the unique factorization theorem holds. In the second field, denoted by Ra[[square root] 10], it is demonstrated that the unique factorization theorem does not hold and therefore ideals are introduced to...

Finite element analysis of culverts under embankments with time dependent and non-linear properties

Creator:: Lertlaksana, Voravit
Abstract:: A computer program was developed for analyzing culverts under earth embankments constructed of compacted cohesive soil using the finite element method. The culvert-embankment system is represented as a two-dimensional plane strain problem. The plane of investigation is taken normal to the culvert axis. The soil-culvert interface is assumed to be...

The natural products chemistry of the red algae Ptilota filicina and Laurencia obtusa

Creator:: Lopez, Albert
Abstract:: The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...

Novel icosanoids from the red marine alga Farlowia mollis

Creator:: Solem, Michele Lee
Abstract:: Farlowia mollis is a marine red alga that grows in the intertidal region along the coast of Oregon. We began studying the chemistry of this alga after a survey of Oregon seaweeds revealed possibly interesting chemistry and antimicrobial activity in its crude organic extract. Over the past three years the...

Mechanical properties of Nb-Ti composite superconducting wires

Creator:: Liu, He
Abstract:: Mechanical properties of Nb-Ti composite superconducting wires were tested at room temperature. The results were analysed using simple composite theory, the rule of mixtures. The objective is to predict the mechanical properties of Nb-Ti superconducting composite wires as a function of volume ratio and geometry of the components, the composite...
