Meiotic chromosome behavior in two tall fescue (Festuca arundinacea Schreb.) genotypes and their sterile hybrid

Creator:: Vásquez, Raul Moreno
Abstract:: Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F ₁ hybrid plants that were sterile. One parent genotype (P₁) was from P. I. 234-906, introduced from Switzerland and the other (P₉) was an introduction from Turkey, P. I. 174-209. P₁ and...

Interconnectedness of Forest Ecosystem Services, Environmental Corporate Impacts, and Corporate Social Responsibility in the Amazon Rainforest

Creator:: Dancé, Raúl
Abstract:: The ecosystem services provided by our forest resources and woodlands are multiple and diverse on all spatial and temporal levels, and include provision, regulating, cultural, and supporting services (Hanson, et al. WRI, 2008). Human activities are proximate and direct drivers of deforestation and forest degradation. In the Latin American region,...

Safety performance of curve advisory speed signs

Creator:: Avelar Moran, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

Creator:: Avelar Morán, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

Enhancing social-emotional and character development for youths' success : a theoretical orientation and an evaluation using a cluster-randomized design

Creator:: Snyder, Frank J.
Abstract:: Interest in social-emotional and character development (SECD) programming has intensified in recent years. SECD-related programs often seek to enhance a variety of health-related outcomes by addressing multiple influences and embracing a comprehensive approach that includes youth, school personnel, families, and communities. Alongside a comprehensive approach arises the need for a...

The Behavioral Responses of Western Toad (Anaxyrus boreas) Larvae to Simultaneous Stressors

Creator:: Reynolds, Emily R.
Abstract:: Animals can be naturally exposed simultaneously to multiple stressors. These include habitat changes, contaminants, diseases, invasive species, parasitism, and predation. Exposure to various combinations of biotic and abiotic stressors may induce behavioral changes that affect the way an individual interacts within its environment.Like other groups of organisms, amphibians are exposed...

Non-Chemical Approaches to Managing Annual Bluegrass (Poa annua L.)

Creator:: Cain, Alyssa B.
Abstract:: Annual bluegrass (Poa annua L.) is a prolific annual grassy weed that can be found worldwide in most landscapes. Known for its ability to produce seedhead at low heights (0.32 cm), thrive in over-maintained areas, and germinate anywhere, annual bluegrass is a highly invasive weed. Due to annual bluegrass’ persistence,...

Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

Creator:: Das-Toke, Shyam P.
Abstract:: Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

Effect of pharmaceuticals and natural products on multidrug resistance mediatedtransport in Caco-2 and MDCKII-MDR1 drug transport models

Creator:: Fan, Ying
Abstract:: This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

Convergent margin magmatism in the central Andes and its near antipodes in western Indonesia : spatiotemporal and geochemical considerations

Creator:: Salisbury, Morgan J.
Abstract:: This dissertation combines volcanological research of three convergent continental margins. Chapters 1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a major Neogene ignimbrite flare- up, yet the least...
