Browse all Theses and Dissertations

Monolayer films of C60 fullerene were for the first time produced successfully by using the Langmuir-Blodgett technique. The processing parameters were optimized and the structure of these films has been investigated using Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM). Film stiffness was measured to be in the range of 15 MPa to 32 MPa depending on the nature of the solvent used to process the films. Optical transparency and electrical performance have been measured and correlated to the film structure. While 100% transparent, the film measured conductivity was in the range of 1013 S/m, that is orders of …

Engineering Technology Vs. Engineering Students: Differences In Perception And Understanding, Anne M. Lucietto, Jennifer D. Moss, Eddy Efendy, R. Mark French

IMPACT Publications

Engineering technology students either are studied under the auspices of research focused on engineering students, or are excluded from engineering research in its entirety. Even when they are included in research, our understanding of engineering technology students is either missing or obscured. The lack of available research focused on engineering technology students in particular has prompted an effort to contribute to the greater body of knowledge of engineering technology education. The lack of research, as compared to other STEM fields, presents a challenge to practitioners in engineering technology programs when making discipline-specific decisions regarding these particular students.

Impacts Of Effective Temperature On Sectional View Drawing Ability And Implications For Engineering And Technology Education Students, Petros J. Katsioloudis

STEMPS Faculty Publications

Temperature can influence thermal comfort, working performance, and social behavior. In a classroom that is slightly cool, an assumption can be made that learning could be affected in a negative way. Considering this, a quasi-experimental study was done to determine if a significant difference of effective temperature have an effect on students’: a) spatial visualization ability, as measured by the MCT and b) ability to sketch a sectional view drawing. While not statistically significant, the students who received treatment using warm water outperformed their peers who received treatment using cold and hot water temperatures, respectively.

Regulation Of The Expression And Activity Of Extracellular Signal-Regulated Kinase 3 (Erk3), Lobna Elkhadragy

Browse all Theses and Dissertations

Mitogen-activated protein kinases (MAPKs) are Ser/Thr kinases that regulate diverse cellular processes. Extracellular signal-regulated kinase 3 (ERK3) is an atypical MAPK that has recently gained interest for its roles in cancer. ERK3 promotes cancer cell migration, invasion and drug resistance, and its expression is upregulated in multiple cancers. However, little is known about the molecular mechanisms that regulate ERK3’s expression and kinase activity. Here, we have identified the oncogenic polycomb group protein BMI1 as a positive regulator of ERK3 level in cancer cells. Mechanistically, BMI1 upregulates ERK3 expression by inhibiting the expression of the tumor suppressor microRNA (miRNA) let-7i, which …

Glycolytic Metabolism And Pregnancy Parameters In The Murine Placenta, Renee Elizabeth Albers

Browse all Theses and Dissertations

The placenta is a complex and essential organ composed largely of fetal-derived cells, including several different trophoblast subtypes that work in unison to support nutrient transport to the fetus during pregnancy. Abnormal placental development can lead to pregnancy-associated disorders that often involve metabolic dysfunction. The scope of dysregulated metabolism during placental development may not be fully representative of the in vivo state in defined culture systems, such as cell lines or isolated primary cells. Thus, assessing metabolic function in intact placental tissue would provide a better assessment of placental metabolism. In this study, we describe a methodology for assaying glycolytic …

Phospholipase D: Key Player In Macrophage-Mediated Inflammation And Resolution, Ramya Ganesan

Browse all Theses and Dissertations

Phospholipase D (PLD) is a cell membrane remodeling and signaling protein implicated in the pathology of chronic inflammation. As PLD is also central to macrophage cell migration, we investigated the molecular basis of PLD's involvement and regulation in macrophage-initiated inflammation (atherosclerosis) and resolution. We have found that PLD is associated with signaling proteins and positively affects cell movement, phagocytosis and NADPH-initiated release of Reactive Oxygen Species (ROS). We found that PLD2 but not PLD1 is important for foam cell formation that causes atherogenesis. We have also found a novel way of inducing macrophage class-switch (polarization) by PLD overexpression. PLD induces …

Proteomic Analysis Of Ischemic Stroke Blood Biomarkers, April Arnold Daubenspeck

Browse all Theses and Dissertations

Stroke is a global burden that claims 6 million lives and permanently disables another 5 million each year. The risk of morbidity and mortality following stroke decreases when early diagnosis and treatment are achieved. However there is no blood test to diagnose ischemic stroke because biomarkers to date have not shown adequate sensitivity and specificity to be adopted into hospital protocols. The overall objective of this dissertation was to identify novel blood protein biomarkers of ischemic stroke. We achieved this by using a number of proteomic and statistical techniques to investigate the differential abundance of proteins in the blood of …

Making Meaning: Shifts In Meaningfulness Across Three Modeling Units, Jeannette Manger

Browse all Theses and Dissertations

Recent reform calls for a more comprehensive approach to science education that positions learners as constructors of knowledge via scientific practices (NRC, 2012; Osborne, 2014). This 'practice turn' shifts from passive science learning to incorporating science actions with epistemic thinking (Duschl & Grandy, 2013; Ford & Forman, 2006; Osborne, 2014; Shouse, Schweingruber, & Duschl, 2007). Teachers are often underprepared in understanding the nuances of scientific practices, and frequently struggle with supporting students in meaningful practice engagement (Abd-El-Khalick & Akerson, 2004; Crawford, 1999; Davis, Petish, & Smithey, 2006; Duschl & Gitomer, 1997). Here, I draw upon the Berland et al. Epistemologies …

Multivariate Calibration Of A Load Sensor For Dynamic And Static Freight Railcar Applications, Dylan Michael Blackwell

Theses and Dissertations

Determination of the load carried by each bearing in a railcar system is crucial to the integrity of the railroad industry. With accurate load measurement, the process of filling a railcar with its specified cargo can be optimized to provide the maximum amount of cargo without exceeding the upper weight limits imposed by the Associations of American Railroads (AAR). An accurate load measurement will additionally make it possible to identify any load imbalance that occurs during periods of travel which result in having a detrimental effect on the health of the bearing. Previous work conducted with a strain-gauge load sensor …
