Exploring Innovative Display Of Painting Through Creating A Dual-Sided Suspended Piece, Erin K. Tichota

SACAD: Scholarly Activities

For this project, I aimed to expand upon my existent painting skills and learn new methods through unconventional techniques for display. My concept of this piece was to convey the sinking and stagnant feeling of being in a rut of depression. The ropes are meant to convey a web of thoughts that the subject is trapped in, while they are sinking deeper in their bed. The dual sided aspect of this project is meant to further emphasize the concept through creating a sense of  duality and permanence.

Selected samples were further characterized by liquid chromatography–mass spectrometry (LC-MS), confirming both the identity and purity …

Mumm Vs. Minium: A Tale Of Two Quarries, Kale Link, Amanda Peng

SACAD: Scholarly Activities

In 2025, a discrepancy was discovered in the field numbers of a selection of mammal fossils, which had been mistakenly catalogued as originating from the Minium Quarry in Graham County, KS instead of the Mumm Quarry in Rawlins County, KS. While both quarries belong to the Ogallala Formation, they demonstrate differing biostratigraphic ages, faunal assemblages, and taphonomic settings. Mumm is Clarendonian aged, while Minium is Hemphillian. To correct this issue, all the Mumm specimens were assigned to an updated locality with more precise geographic and biostratigraphic data.

Mangroves are important carbon sinks and play a key role in the global climate system, yet tropical estuaries such as the Wouri estuary, Cameroon, remain poorly studied. This study aims to improve understanding of how organic matter varies with depth within mangrove sediments. Sediment cores were collected from two locations within the estuary: Dibamba River mangrove (DM; 3°56′14.0″N, 9°44′54.0″E) and Koo tidal creek mangrove (KM; 3°57′36.0″N, 9°38′51.0″E). Sediments were subsampled at regular depth intervals and analyzed using Loss on Ignition (LOI). Samples were dried at 105 °C for 48 hours to determine moisture content, heated at 550 °C for 4 …

Hydrodynamic Control On Organic Matter Deposition In Mungo And Dimbamba (Wouri Estuary)”, Maimouna Traore

SACAD: Scholarly Activities

This study investigates how hydrodynamic energy controls organic matter (OM) deposition in the Wouri Estuary using sediment cores from Mungo and Dimbamba. OM was determined using the Loss on Ignition (LOI) methods with samples dried at 105°C  for 48 hours and combusted at 550°C for 4 hours .

High OM values at Mungo (27.4–42.6%) indicate a low-energy environment that promotes sediment deposition and OM preservation. In contrast, low OM values at Dimbamba (15.7–30.5%) reflect high-energy conditions that enhance sediment reworking and limit OM accumulation.

These results confirm that OM content is an effective proxy for hydrodynamic energy and depositional processes.

An Evaluation Of The Anomie Theory In The Criminal Justice System, Emma K. Schneider

SACAD: Scholarly Activities

Anomie Theory is a sub-theory of social structure theory and focuses on someone's sense of normlessness when society is ever-changing, and a person of low economic status lacks social ties or a way to legitimately obtain the goals of social norms, resulting in resorting to aggravation and anger. Émile Durkheim originated the idea and went on to give a new way to observe and study crime. The criminal justice system implements this through federal aid and help after imprisonment, but there is still a lot that can be done to progress this theory. This occurs in everyday life, and it …

Exploring Ancestral Enzymes Through Sequence Reconstruction And Stability Prediction, Jeyun Park, Masakatsu Watanabe

SACAD: Scholarly Activities

Proteins evolve through sequence changes that shape structure, stability,

and function. Ancestral sequence reconstruction (ASR) infers ancestral

proteins from modern homologs, but many studies focus on sequence

inference without evaluating structural or energetic feasibility.

β-lactamases provide an ideal model due to their evolutionary diversity and

clinical relevance in antibiotic resistance.

Here, we present an integrated ASR workflow combining phylogenetic

inference (IQ-TREE), ancestral reconstruction, and structural and stability

validation using AlphaFold and FoldX. By reanalyzing a curated β-

lactamase dataset and comparing with a recent study (Risso et al., 2013),

we provide a controlled comparison of ancestral sequences, predicted

structures, and …
