Design And Evaluation Of A Home- Scale Arsenic Removal System, Megan Alferness, Alexandria Casares

Civil, Environmental and Sustainable Engineering Senior Theses

The problem of arsenic contamination affects millions of people worldwide. A home-scale arsenic removal system could provide families in Nepal access to clean drinking water. It would also reduce the risk of adverse health issues that are associated with ingesting arsenic contaminated water. Our experiments show that using electrocoagulation is an effective method of removing arsenic from water. We were able to get the level of arsenic below 10 ppb in 60 minutes of treatment using various system configurations. We identified several parameters that affect the treatment process, the most important being the charge loading, or the amount of charge …

Pavement patching is a common maintenance activity in the state of Ohio, due to numerous freeze-thaw cycles. The Ohio Transportation (ODOT) has a need for durable, more permanent high performing pavement and bridge deck materials that allow for a faster repair and for user safety. New or proprietary products were chosen, installed, and monitored in order to specify for use in future ODOT construction, based on the field performance of the products. The objective of this study was to document the investigation, installation, and field testing of the previously chosen high performance patching materials. The investigation determined the proper field …

Developing Improved Bridge Parapet Designs, Lauren A. Hedges

ETD Archive

The Ohio Department of Transportation has identified that premature parapet cracking is a significant problem in Northeast Ohio. Background research related to concrete cracking and parapet cracking was conducted to determine possible causes of the premature cracking that ODOT has discovered. To further look at possible causes of this cracking, current ODOT bridge parapet practices were reviewed. In addition to ODOT practices, ten other state DOTs were surveyed to identify the bridge parapet practices used. These practices include the parapet design characteristics, construction joint spacing and depth, and the class of concrete used for construction. Various differences among all of …

Dynamic Testing Procedures For Performance Assessment Of Nuclear Fuel Rods, Travis M. Adams

Honors Theses and Capstones

Existing transportation probabilistic risk assessment for spent nuclear fuel in the United States is based on short-term (decades) on-site storage at power plants before transport. Updated risk assessment estimates will be required as extended on-site storage (centuries) and higher burnup levels in fuel become standard. Nuclear fuel rods under these two conditions are more brittle than rods from short-term storage and intermediate burnup due to several mechanisms, including hydrogen embrittlement. Development of risk assessment requires characterizations of dynamic behavior of these degraded rods under transportation scenarios. This Honors thesis provides an initial literature review for a larger project that will …

Pile-Soil Interaction In Unsaturated Soil Conditions, Megan Hamilton

Honors Theses and Capstones

The degree of saturation has been proven to significantly affect geotechnical engineering designs for foundations. The changes in water content will influence the way the soil behaves, including its strength and stiffness parameters. These characteristics were analyzed for a uniform silty sand by developing P-Y curves, which relate lateral loading to lateral deformations. These P-Y curves were input into FB-Multipier, a software developed by the Bridge Software Institute. The software is capable of generating deformations as a result of user-defined loading cases. The results indicated that the middle range of degrees of saturation produced the least amount of deformation. This …

Estimating Connecticut Stream Temperatures Using Predictive Models, Erik Carlson

Honors Theses and Capstones

The Connecticut Department of Energy and Environmental Protection (CT DEEP) seeks to better classify their streams into thermal regimes (cold, cold transitional, warm transitional, and warm water). A prediction model was created based upon physical characteristics such that CT DEEP could classify streams into thermal regimes based upon the parameters described in Lyons et al. 2009 and compare them to their own classification system. Accurately classifying these thermal regimes determines the environmental protection provided to a stream as well as the potential for establishing fisheries.

The immediate objective of this research is to determine if it is important to provide exposure of BIM to undergraduate or graduate students in the civil engineering curricula and if so to …

Wired For Business: The Roebling Story., Kelley Marie Hatch-Draper

Electronic Theses and Dissertations

John Augustus Roebling, a classically educated civil engineer and young Hegelian, immigrated to America in 1831 in search of freedom from a repressive political system that afforded him no opportunity for advancement. Arriving in the midst of the American market revolution, his dream of establishing an agrarian farming colony changed in response to societal transformations resulting from mechanization and the rise of industry. Within forty years, Roebling achieved fame as a canal engineer and bridge designer while establishing the American wire rope industry. Without Roebling's innovation in wire-rope, modern suspension bridges, high-rise elevators, construction cranes, and cable cars would not …
