Underemployed husbands : a profile of hardship and assessment of marital and personal qualities

Creator:: Guss, Thomas O.
Abstract:: Prior to 1986, economic conditions resulted in substantial unemployment, layoffs, and reduced work time. Such conditions produced underemployment resulting in significant income reductions for families. A random sample of a non-metropolitan Northwest community elicited 137 couples from a variety of incomes. Twenty-one of them were found to have incomes reduced...

The evolution of student understanding of the concept of derivative

Creator:: Zandieh, Michelle J.
Abstract:: This research seeks to answer the question, "What does it mean for a student to understand the concept of derivative?" A structured way to describe an individual student's understanding of derivative is developed and applied to analyzing the evolution of that understanding for each of nine high school seniors during...

Techniques of solvent extraction of organic material from natural waters

Creator:: Cronin, John Thomas, 1935-
Abstract:: Manual and automatic solvent extraction techniques were used to concentrate organic material from natural waters. Field and laboratory extractions were compared to determine the most probable method and best solvents for efficient concentration of organic material from estuarine and sea waters. The large scale extraction processes utilizing extractors made from...

Age-related decrease in resilience against acute redox cycling agents: Critical role of declining GSH-dependent detoxification capacity

Creator:: Thomas, Nicholas O.
Abstract:: Over the past century, life expectancy in the United States has dramatically increased leading to an increasingly aging population with people reaching, and spending more years in ‘old age’. While this unprecedented shift in population demographics represents great strides for humanity, it is not without cost. One consequence of longer...

Effect of Zinc, Copper and Selenium supplementation on the humoral immune response of weaned beef steers

Creator:: Dill, Thomas O.
Abstract:: Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...

Surface Modification to Enhance Corrosion Resistance of Carbon Steels using Additive Manufacturing

Creator:: Murkute, Pratik V.
Abstract:: Low carbon steels (LCS) due to their high strength-to-cost ratio are one of the most ubiquitous materials used for a wide range of applications, including but not limited to automotive, construction, and transportation. However, the low corrosion resistance of LCS in neutral, acidic, or saline environments limits its utilization and...

Paclobutrazol and nutrient treatment effects on ovation perennial ryegrass

Creator:: Turner, J. Kevin
Abstract:: Rapid tiller and root production can improve seedling survival and benefit stand establishment of perennial ryegrass (Lolium perenne L.) in commercial seed fields. Environmental conditions after establishment and inherent morphological factors combine to reduce the commercially harvested yield below the theoretical potential yield. These studies were conducted to determine if...

High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

Creator:: Barber, Jeffrey
Abstract:: The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

Occurrence, transmission, and properties of strains of cucumber mosaic virus that are seed-transmitted in Phaseolus vulgaris

Creator:: Davis, Robert Francis
Abstract:: A survey of major bean (Phaseolus vulgaris) breeding programs and seed producing areas in Idaho, Washington, and Oregon was conducted to determine the occurrence of cucumber mosaic virus (CMV), recently reported to be seedborne in beans. Some 259 plants, sampled from breeding lines of diverse germplasm, were found by enzyme-linked...

The impact of grazing on forage quantity, quality and foliar cover of the herbaceous vegetation in the Mamora Cork Oak Forest, Morocco

Creator:: Mejjati-Alami, Mohammed
Abstract:: This research was conducted in the Mamora cork oak forest of Morocco to: (1) Describe the impacts of sheep grazing (none, 35% use, 70% use) in March, April, May and June of 1987 and 1988 on seasonal forage production; (2) evaluate the effects of these factors on annual changes in...
