Pollen, the male product of the flower, is a crucial component in plant reproduction, as it transmits the sperm cells to the female structures, enabling fertilization and subsequent seed production. A major transition of the pollen life cycle, triggered upon pollination of female floral tissue, is from a dormant pollen...
Empathy is considered a significant motivator of prosocial behavior. Increasing evidence suggests that feelings of personal distress associated with empathy may be stronger or weaker according to the form of perspective taking that an empathizer utilizes. The aim of the present study was to further quantify the stress consequences and...
Swelling soils cause millions of dollars of damage to buildings every year in the Unites States alone. One essential piece to understanding these soils is to understand how water moves through them. Hydraulic conductivity is a measure of how easily water flows through a soil. Currently, the most common method...
Although the question of free will has persisted throughout the history of philosophy as an important metaphysical consideration, rarely does the inquiry include empirical evidence from other disciplines concerned with human behavior. In this interdisciplinary paper, I combine the wisdom of psychologists, metaphysicians, and philosophers of science to comment on...
The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...
This thesis explores the relationship between design cycle models and knowledge management systems applied to various physical prototypes that the author developed from 2020 to 2023. The author walks through the process of prototyping a potty-training device in OSU’s Prototype Development Lab and an automated testing fixture for her Senior...
Organizational values are an important factor in the work of many organizations and can guide both day-to-day decision-making and long-term strategic planning. Little previous research has documented the impact of core values on individual performance in military environments nor the effect of core values on leadership attributes. In this study,...
Electroencephalogram (EEG) signals have recently gained attention to classify associated hand movement. This is particularly useful for amputees with prostatic hands or people who are unable to move their hands voluntarily. Among the decoding algorithms used to classify hand movements are support vector machines and multilayer perceptron networks. In this...
This project examines the results of current-voltage conduction mechanism analysis techniques simulated under assumed conduction conditions. Thermionic emission and Fowler-Nordheim tunneling conditions are simulated and analyzed. The resulting plots show how devices behave under different condition mechanisms. The effects of different conduction mechanisms on the results of various analysis techniques...
A period of over forty years (1913-1954) of gold dredging dramatically changed
the landscape of Sumpter Valley, Oregon into a rocky, uninhabitable terrain. The Defrees
Ranch LLC used cattle feeding to increase top soil, vegetation, and habitat on the dredge
tailings. This thesis investigated the use of feeding cattle as...
