Molecular factors that influence host range and virulence of A. tumefaciens

Creator:: Castle, Linda A.
Abstract:: Agrobacterium tumefaciens is a common soil bacterium that causes crown gall disease on many dicotyledonous plant species. It has been exploited for use in genetic engineering because it is able to promote transfer of any DNA segment to plant chromosomes. Many molecular factors in both the plant and bacterium contribute...

Taxonomy and host specificity of the genus Agrobacterium

Creator:: Anderson, Arthur Robert
Abstract:: One hundred seventy-eight Agrobacterium isolates, 120 United States (U.S.), 26 Australian and 32 of miscellaneous origin, were characterized for their reactions to 20 biochemical and physiological tests. Isolate pathogenicity and degree of host specificity, utilization of nopaline and octopine, and sensitivity to agrocin-84 also were determined. The U.S. isolates were...

Numerical methods for variable permeability magnetostatic field problems

Creator:: Anderson, Lee Roy
Abstract:: Solutions to the variable permeability magnetostatic field problem are achieved in both rectangular and cylindrical coordinates for a wide variety of magnet geometries. The resulting difference equations are solved iteratively and a method is provided which substantially increases the rate of convergence for these type of problems. Magnetization curves for...

Engineering analysis of a rotary dryer : drying of wood particles

Creator:: Kamke, Frederick A.
Abstract:: Rotary dryers are the most commonly used wood drying system in the particleboard industry. These dryers also play an increasingly important role in drying wood residues for fuel. Many potential benefits may be realized through an improved understanding of the rotary drying process. A rotary dryer simulation model was developed,...

Landscape-Level Approaches to Desert Bighorn Sheep (Ovis canadensis nelsoni) Conservation in a Changing Environment

Creator:: Creech, Tyler G.
Abstract:: Landscape characteristics can strongly influence demographic and genetic processes in wildlife populations. Climate change and human land use are causing many landscapes to change rapidly, and the effects on wildlife populations must be understood to properly manage these threats and design effective conservation strategies. In this dissertation, I explored the...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

A theoretical design of rational autonomy : integrating elementary and early childhood teacher education through a contemporary derivation from Maria Montessori's social cognitive field paradigm

Creator:: Mitchener, Virginia Wedler
Abstract:: The individual through earliest recorded history reveals contradictory views of the human life-span. "Am I a free and unique individual, able to make choices and decide my own destiny?, or, "Am I only a victim of circumstance, a speck of dust in the universe's whirlwind of fate?" Each view is...

Caution! High Water: A Historical Archaeological Investigation of the Champoeg Townsite (ORMA26) after the 1861 Flood

Creator:: Hill, Cayla L.
Abstract:: The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...

It Depends: Defining Cooperation and Evaluating Effectiveness in Transboundary Waters

Creator:: McCracken, Melissa J.
Abstract:: With the increasing international focus on transboundary cooperation as a part of the Sustainable Development Goal (SDG) Framework, there is global recognition of transboundary water cooperation as a tool for improved governance and management of transboundary surface and groundwaters. Yet, there is not an agreed upon definition of transboundary water...
