Short Beam Shear Strength Evaluations Of Gfrp Composites: Correlations Through Accelerated And Natural Aging, William Todd Barker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fiber Reinforced Polymers (FRP) composites have been materials of interest in replacing or reinforcing steel, wood, and concrete, but lack of understanding of degradation under physical and chemical aging is a main concern. Through many years of research, the understanding of aging or durability of GFRPs has improved. To be able to evaluate aging related degradation rates, an accelerated aging methodology under varying environments is introduced. Accelerated aging is a concept used to age composites in a lab controlled environment under varying pH conditions (2 to 13) and temperatures (~ -20° to +160°F). Once acceleratedly aged testing is completed, Arrhenius …

Colleges and universities across the U.S. continue their efforts to enroll students from diverse backgrounds. Those students from lower socioeconomic (SES) backgrounds and first in their family to attend college have been found to experience a great deal of challenges once enrolled. Individuals from different class backgrounds have been shown to experience a different form of socialization, which may influence their experiences in higher education both positively and negatively. There is limited research, however, on how the presence of internal and external characteristics influence the way in which students make sense of themselves within these new environments. This is particularly …

Student-Instructor Out-Of-Class Communication: A Media Multiplexity Approach, Cathlin V. Clark-Gordon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present set of studies examined media multiplexity theory (MMT; Haythornthwaite, 2005) in the context of student-instructor out-of-class communication (OCC) in two samples: undergraduate and graduate students. It was predicted that student-instructor tie strength (closeness) would lead to a greater number of modes used for OCC, and subsequently, the number of modes used for OCC would predict positive classroom outcomes, including communication satisfaction, cognitive and affective learning, and motivation. It was also predicted that the effect of closeness on the number of modes used for OCC would be moderated by student’s enjoyment of online communication, insofar as it would suppress …

Transfer Of Fusarium Head Blight Resistance To Hard Red Winter Wheat, Hongbin Tao

Plant Sciences

Fusarium head blight (FHB; caused by Fusarium graminearum Schwabe) is a serious disease of hard red winter wheat (HRWW) in North Dakota. Current varieties are lacking in resistance. Many resistance quantitative trait loci (QTL) were discovered in spring wheat that can be employed in HRWW. The North Dakota State University breeding program aims to acquire and pyramid useful FHB resistance QTL into its breeding population. Therefore, hybrid populations derived from CM82036 (Fhb1 and Qfhs.ifa-5A), PI277012 (Qfhb.rwg-5A.1 and Qfhb.rwg-5A.2), Frontana (Qfhs.ifa-3A), and TA5660 (Fhb6) were tested for type II resistance to: derive new FHB resistant HRWW lines with pyramided QTL (Fhb1+) …

Influence Of Tomato (Solanum Lycopersicum L.) Seedling Grafting On Plant Growth, Fruit Yield And Quality, And Disease Tolerance, Suman Parajuli

Plant Sciences

Influence of tomato (Solanum lycopersicum L.) seedling grafting on the plant growth, fruit yield and quality, and disease tolerance were investigated using 3 cultivars (Big Beef, Celebrity, Cannonball) as scions and two Solanum species (B-blocking, Maxifort) as a rootstock in a randomized complete block design with three replications. The grafted plants were statistically higher in values for stem diameter, leaf chlorophyll, and fruit carotenoid contents. Similarly, the scion/rootstock combination ‘Big Beef/Maxifort’ and ‘Big Beef/B-blocking’ had prolonged days to maturity and gives a higher yield than the non-grafted ‘Big Beef’. Grafting seedling on ‘Maxifort’ and ‘B-blocking’ rootstocks improves the fruit quality …

Optimal Seeding Rates For New Hard Red Spring Wheat Cultivars In Diverse Environments, Jordan D. Stanley

Plant Sciences

Seeding rate in hard red spring wheat (HRSW) (Triticum aestivum L.) production impacts input cost and grain yield. Predicting the optimal seeding rate (OSR) for HRSW cultivars can aid growers and eliminate the need for costly seeding rate research. Research was conducted to determine the OSR of newer HRSW cultivars (released in 2013 or later) in diverse environments. Nine cultivars with diverse genetic and phenotypic characteristics were evaluated at four seeding rates in 11 environments throughout the northern Great Plains region in 2017-2018. Results from ANOVA indicated environment and cultivar were more important than seeding rate in determining grain yield. …
