A History Of The Geology Program At The University Of Tennessee At Martin, Michael A. Gibson
A History Of The Geology Program At The University Of Tennessee At Martin, Michael A. Gibson
The Compass: Earth Science Journal of Sigma Gamma Epsilon
The teaching of geology has as long a history as The University of Tennessee at Martin has itself, extending back to 1901 when the first geology class was offered at the campus’s original institution, Hall-Moody Institute, a small Baptist college. Geology, usually with geography, was offered as a service course to the primary programs of agriculture, education and, later, engineering. Faculty turnover during these formative years was frequent. When the school was acquired by the University of Tennessee in 1927 and became UT Junior College, geology remained a service course. Geology offerings had been expanding since 1947 and, in 1951, …

Structural And Geomorphological Constraints On The Activity Of The Sparta Fault (Greece), Çal Çağatay, Sarah Boulton, Zoe Mildon
Structural And Geomorphological Constraints On The Activity Of The Sparta Fault (Greece), Çal Çağatay, Sarah Boulton, Zoe Mildon
School of Geography, Earth and Environmental Sciences
The ancient city of Sparti (Greece) suffered extensive damage from an estimated Mw 7.2 earthquake in 464 BCE, resulting in c. 20 000 fatalities, but questions remain about the short-(c. 104 years) and long-term (105–106 years) activity of this important structure. This paper presents new structural data and fluvial geomorphological analysis from the Sparta Fault and, in particular, considers the less well-known northern fault segment. A new topographic profile on the well-developed post-glacial fault scarp from the northern strand indicates a 7.53 m offset over the last c. 15 ka, suggesting a throw-rate of c. …

CLCWeb: Comparative Literature and Culture
In his article "Chinese Ideas and American Politics: Confucius as a Guideline for Leadership", Alfred Hornung traces the influence of Chinese ideas on American politics with a focus on the works of Confucius. The more than 2.500-year-old impact of the Chinese philosopher on public conduct and his pursuit of virtuous perfection has served as a guideline for leadership emanating from China to Europe and America. For this trajectory of ideas, the historic and the new Silk Road play a decisive role. The exchange of goods along the land-based and maritime routes, which inform Xi Jinping's Belt and Road Initiative, also …
Exploring Intraplate Seismicity In The Midwest, Alexa Fernández
Exploring Intraplate Seismicity In The Midwest, Alexa Fernández
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Intraplate seismicity represents a notable occurrence within the stable North American Craton. This research explores the potential sources of stresses that could reactivate older faults and influence seismic activity within this region. Among these sources, the enduring impact of the last glacial period is considered, which includes continued glacial isostatic adjustments (GIA). During GIA the lithosphere rebounds due to the retreating ice, and the forebulge caused by far-field flexure in response to the glacial load, collapses. This results in significant faulting, fracturing, and seismic activity associated with the deglaciation phase. The adjustment of the lithosphere manifests as both near surface …

Castor Oil-Based Polyurethane Adhesives: Effect Of Cross-Linker On The Bond Strength, Mayankkumar Chaudhary
Castor Oil-Based Polyurethane Adhesives: Effect Of Cross-Linker On The Bond Strength, Mayankkumar Chaudhary
Electronic Theses & Dissertations
Adhesives are important for binding diverse materials, promoting structural integrity and functional versatility in countless daily life applications. An enormous obstacle remains in the development of polyurethane (PU) adhesives exhibiting excellent bonding strength. Designing a chain extender with appropriate molecular structures is critical to improving the bonding strength of PU-based adhesives. In this work, PU-based adhesive was prepared using castor-oil-based polyol (COP) and diisocyanate. The bonding strength of the adhesive was improved by adding chain extenders such as N, N-bis(2-hydroxyethyl) thiophene-2,5-dicarboxamide (ETP) and N, N-Bis(2-hydroxyethyl)-terephthalamide (ETAM). The modified adhesive showed high bonding strength after the addition of chain extenders due …
