Many chemical and physical factors govern the mobility of metal contaminants in soils and clay systems; some of these chemical factors include mineralogical composition, cation exchange capacity, organic matter content, pH and the ionic strength of soil water. This makes underst…

A Saudi bentonite natural clay was investigated as an adsorbent for the Basic Blue 3 dye from wastewater. A batch adsorber was used to determine the pore diffusivity and the equilibrium isotherms, and a fixed bed adsorber was used to determine experimental breakthrough curves fo…
Pressure solution (PS) is the most important ductile deformation mechanism in the earth's upper crust. During pressure solution rock is dissolved at zones of higher stress, transported through the pore-filling fluid phase and precipitated at zones of lower stress. This can occur…
Electrokinetic soil processing is an innovative insitu technique to remove contaminants from soils and groundwater. The process is an alternative to conventional processes, with significant economic and technical advantages. A theory is presented for pH gradient development by d…
The objectives of this study were to evaluate the effects of soluble salt concentration (i.e., salinity) on geotechnical characteristics and sedimentation behavior of fine-grained soils (e.g., mine tailings) and identify test methods applicable for characterizing high-saline soi…
Red siliciclastics and evaporites of Permian Nippewalla Group in mid-continental US were deposited in western equatorial Pangea. Previous studies of these rocks record Permian air temperatures as high as 73 °C, saline lake waters with a pH as low as ~1, and sedimentology that sh…
This paper aims to highlight the different forms of writing within the Americas, establish connections between the systems, and discuss the impact of European colonization. Writing systems within the American Continents contain a vast array of different indigenous systems that f…
As climate change threatens vulnerable tropical climates and development outpaces resource availability, the need for diverse construction material grows. The United Nations Sustainable Development Goals aim to reduce poverty in all forms. Diversifying construction material work…
The overarching purpose of my practice has been an effort to find personal fulfillment while living my religion through making sculpture. For the last several years, I have primarily used plants as my subject. I have always loved enveloping myself in nature and experienced a sig…
Soil-structure-interaction (SSI) plays an important role in seismically-induced ground failure; however, the contribution is poorly understood and rarely considered in geotechnical engineering practice. Semi-empirical methodologies used in practice to evaluate ground failure sol…
Chemistry is key to gaining control of the entire ceramic process. I experimented with clay and glaze chemistry to achieve my aesthetics, which include my interests in visual and textural clay surfaces, as well as iridescence. I accomplished this in three ways: creating Shigarak…
Unit 13 began it’s journey with an interest in extending the discipline of architecture. By challenging and ques- tioning the traditional norms and stan- dards of architecture - we will begin de- signing new architectures and forging forward new futures. Our theme for the year i…
The Marcellus Shale is the largest natural gas producing formation in the Appalachian basin, and as such, presents a unique opportunity for continued research on an area that is critical to meeting the energy needs of the current society. Although the Marcellus has historically …
