Analysis Of Potential Alkali Reactivity Of Aggregates In Arkansas, Brigita Dowling

Civil Engineering Undergraduate Honors Theses

Alkali Silica Reaction (ASR) is a deleterious chemical reaction in concrete that leads to the deterioration of concrete structures. This reaction occurs between minerals present in aggregates and alkalis in the cement, and produces a gel-like substance called alkali silicate gel. Gradually, these gels absorb water from the environment and expand, leading to internal stresses in the concrete. This damage results in expansion, cracking, and deformation, reducing the strength and durability of the concrete significantly. While this damage appears minor initially, eventually they can lead to the need for costly repairs or replacement of the concrete. ASR has been observed …

Beyond Duality: The Doppelganger And The Multiplicity Of Identity In Oscar Wilde's The Picture Of Dorian Gray, Alyssa Roberts

Theses, Dissertations and Culminating Projects

This paper argues that Oscar Wilde uses The Picture of Dorian Gray to transform the Gothic doppelganger from a symbol of moral duality into a site of multiplicity that exposes the instability of identity. Earlier iterations of the double–ranging from mythic traditions to nineteenth-century texts—such as The Strange Case of Dr. Jekyll and Mr. Hyde—tend to structure the self through binary opposition. Wilde, however, reconfigures the double as an accumulative and dynamic process. This paper analyzes how Wilde disrupts the rigidity of Victorian binaries and society’s investment in duality through the portrait’s accumulation of the consequences of Dorian’s actions as …
