Mahler's order functions and algebraic approximation of p-adic numbers

Creator:: Dietel, Brian Christopher
Abstract:: If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

Genres at Play : History, Tragedy, and Comedy in Shakespeare's Richard II

Creator:: Wiley, Marie
Abstract:: This thesis examines a range of generic influences in William Shakespeare's Richard II. By exploring the play's references to conflicting interpretations of history from different generic perspectives, I hope to advance a more nuanced reading of the play's dynamic staging of history. In Chapter One, I suggest that Richard II...

The Biogeochemistry of nitrogen and phosphorus cycling in native shrub ecosystems in Senegal

Creator:: Dossa, Ekw'e Lokossou, 1960-
Abstract:: Two native shrub species (Piliostigma reticulatum and Guiera senegalensis) are prominent vegetation components in farmers’ fields in Senegal. However, their role in nutrient cycling and ecosystem function has largely been overlooked. A study including both laboratory and field experiments was conducted to evaluate potential biophysical interactions of the two shrub...

Effects of green manures on verticillium wilt of potatoes and on soil properties related to disease suppression

Creator:: Ochiai, Naoyuki
Abstract:: Increasing regulation and costs of soil fumigation to manage diseases such as Verticillium wilt caused by soil-borne pathogens have prompted a search for management alternatives. Single-year microplot experiments were conducted in 2002 and 2003 in central Oregon to evaluate the effects of Austrian winter pea, broccoli, and Sudan grass green...

Winter cover cropping effects on integrative biological indicators of soil quality

Creator:: Ndiaye, Evelyne L.
Abstract:: Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...

Activity, composition and structure of soil microbial communities in Savannahshrubs of agroecosystems in semi-arid Senegal

Creator:: Diedhiou, Sire
Abstract:: Piliostigma reticulatum and Guiera senegalensis are two native shrubs that coexist with row crops in parkland systems of the Sahel of Africa. Although permanently green all year around in soil depleted in nutrients and dry for a nine-month period, these shrubs have been largely overlooked. Conventional management of these shrubs...

Fatty acid profiling of soil microbial communities : a comparison of extraction methods and temporal dynamics in plant residue amended soils

Creator:: Fernandes, Marcelo Ferreira
Abstract:: A method based on fatty acid (FA) analysis is used to profile microbial community structure (MCS). Various extraction protocols are available, which alter the types of FAs extracted from soils. The more time consuming but widely used protocol extracts only FAs from phospholipids (PLFA). This technique is desirable because PLFAs...

Microbial community structure as influenced by season and stand age in a Douglas-fir (Pseudotsuga menziesii) ecosystem

Creator:: Kucera, Jennifer Moore
Abstract:: Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...

Soil biological, chemical, and physical dynamics during transition to non-thermal residue grass-seed management systems

Creator:: Barry, Amanda Nell
Abstract:: Legislation to reduce the annual limit of field burning in Oregon has led to increased study of alternative non-thermal grass-seed management methods. Of these methods, non-thermal residue management, in combination with crop rotations and different tillage practices, offer potential to equal or exceed crop production of conventional thermal production systems....
