Sequential isotopic analysis to characterize ontogenetic shifts and growth dynamics of loggerhead sea turtles (Caretta caretta)

Creator:: Ramirez, Matthew D.
Abstract:: Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...

It’s in Their Bones: Ecological Drivers of Kemp’s Ridley Sea Turtle (Lepidochelys kempii) Somatic Growth and Population Dynamics

Creator:: Ramirez, Matthew D.
Abstract:: Somatic growth variation manifests from the cumulative effects of a suite of biological, ecological, and environmental processes and can have profound effects on individual fitness and species population dynamics. As ectotherms whose growth dynamics are greatly influenced by environmental factors, sea turtles display considerable variation in somatic growth within and...

Mitochondrial decay in the aging rat heart : changes in fatty acid-supported bioenergetics and macromolecular organization of the electron transport system

Creator:: Gómez Ramirez, Luis A.
Abstract:: Decline in cardiac pump function is a hallmark of aging where mitochondrial decay is an important underlying cause. Although certainly multifactorial in nature, both dysfunction of the machinery involved in the chemiosmotic process of energy transduction and lower capacity to maintain fatty acid-driven respiration are identified as intrinsic factors of...

Latinx Students in Latinx Fraternities and Sororities

Creator:: Martinez, Clara L.
Abstract:: The purpose of this study was to look at how Latinx fraternities and sororities influence a Latinx student’s identity development, academics, and their sense of belonging at a historically white university. A qualitative narrative study was utilized to understand the experiences of the four participants and their responses to the...

The Social Interactions of Pseudomonas aeruginosa

Creator:: Smith, Parker
Abstract:: Pseudomonas aeruginosa is a ubiquitous environmental microbe, opportunistic pathogen, and a highly social organism. P. aeruginosa utilizes a wide array of cooperative behaviors to adapt to the environmental conditions around it. These behaviors include quorum sensing (QS), a form a cell-to-cell signaling that coordinates the expression of secreted products in...

Impact of Butterfat Content and Composition on the Quality of Laminated Pastries

Creator:: Ramirez, Sebastian
Abstract:: Butter has long been the premium choice for producing pastries such as Danish and croissants. Its inclusion has consistently delivered characteristically light and airy crumbs with beautifully flaky crust. Once considered a delicacy, pastries have now become innocuous in our everyday lives. Once requiring a skillful hand to sculpt and...

Skew Brownian motion and branching processes applied to diffusion-advection in heterogenous media and fluid flow

Creator:: Ramirez, Jorge M.
Abstract:: This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics. In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...

Engineering Student Perspectives of a New Required Programming Course

Creator:: Garcia Ramirez, Jessica
Abstract:: We present student perceptions of a new first-year engineering programming class that was designed by informed research practices. While the College of Engineering at Oregon State University saw a lot of major switching in the first year, there were not many students switching into computer science (CS). This could have...

The Impacts of a New Programming Course in a First-Year Engineering Experience

Creator:: Garcia Ramirez, Jessica
Abstract:: This research paper describes the impacts of a new programming class on first-year, non-CS engineering students. In the spring of 2021, the College of Engineering at Oregon State University piloted a new programming course that will be required of all engineering majors in the following academic years. We used the...

Experimental analysis of intra- and interspecific competitive interactions between cutthroat trout and sculpins in small streams

Creator:: Ramirez, Ben S.
Abstract:: In the Pacific Northwest ecoregion of North America, sculpins represent a major constituent of freshwater assemblages in coastal rivers. Based on their prevalence and abundance, sculpins are likely important ecologically, yet little is known of their interactions with co-occurring species, such as widely studied salmon and trout (salmonines). In this...
