More Favorable Combination Of Circumstances Could Hardly Have Been Desired : A Bottom To Top Examination Of The Pittsburgh And Boston Mining Company's Cliff Mine, Sean M. Gohman

Dissertations, Master's Theses and Master's Reports - Open

The Cliff Mine, an archaeological site situated on the Keweenaw Peninsula of Michigan, is the location of the first successful attempt to mine native copper in North America. Under the management of the Pittsburgh & Boston Mining Company from 1845-1879, two-third of the Cliff’s mineral output was in the form of mass copper, some pieces of which weighed over 5 tons when removed from the ground. The unique nature of mass copper and the Cliff Mine’s handling of it make it one of the best examples of early mining processes in the Keweenaw District. Mass copper only constituted 2% of …

Simulating Dioxane Transport In A Heterogeneous Glacial Aquifer System (Washtenaw County, Michigan) Using Publicly Available Models And Data, Rungroj Benjakul

Dissertations, Master's Theses and Master's Reports - Open

The primary challenge in groundwater and contaminant transport modeling is obtaining the data needed for constructing, calibrating and testing the models. Large amounts of data are necessary for describing the hydrostratigraphy in areas with complex geology. Increasingly states are making spatial data available that can be used for input to groundwater flow models. The appropriateness of this data for large-scale flow systems has not been tested. This study focuses on modeling a plume of 1,4-dioxane in a heterogeneous aquifer system in Scio Township, Washtenaw County, Michigan. The analysis consisted of: (1) characterization of hydrogeology of the area and construction of …

Parametric Analysis Of A Coupled Photovoltaic/Thermal Concentrating Solar Collector For Electricity Generation, Todd Otanicar, I. Chowdhury, P. E. Phelan, R. Prasher

Mechanical Engineering Faculty Works

The analysis of the combined efficiencies in a coupled photovoltaic (PV)/thermal concentrating solar collector are presented based on a coupled electrical/thermal model. The calculations take into account the drop in efficiency that accompanies the operation of PV cells at elevated temperatures along with a detailed analysis of the thermal system including losses. An iterative numerical scheme is described that involves a coupled electrothermal simulation of the solar energy conversion process. In the proposed configuration losses in the PV cell due to reduced efficiencies at elevated temperatures and the incident solar energy below the PV bandgap are both harnessed as heat. …

Nanofluid-Based Direct Absorption Solar Collector, Todd Otanicar, P. E. Phelan, R. S. Prasher, G. Rosengarten, R. A. Taylor

Mechanical Engineering Faculty Works

Solar energy is one of the best sources of renewable energy with minimal environmental impact. Direct absorption solar collectors have been proposed for a variety of applications such as water heating; however the efficiency of these collectors is limited by the absorption properties of the working fluid, which is very poor for typical fluids used in solar collectors. It has been shown that mixing nanoparticles in a liquid (nanofluid) has a dramatic effect on the liquid thermophysical properties such as thermal conductivity. Nanoparticles also offer the potential of improving the radiative properties of liquids, leading to an increase in the …

Integration Of Remote Lidar And In-Situ Measured Data To Estimate Particulate Flux And Emission From Tillage Operations, Vladmir V. Zavyalov, Gail E. Bingham, Michael D. Wojcik, Jerry L. Hatfield, Thomas D. Wilkerson, Randy S. Martin, Christian Marchant, Kori D. Moore, Bill Bradford

Civil and Environmental Engineering Faculty Publications

Agriculture, through wind erosion, tillage and harvest operations, burning, diesel-powered machinery and animal production operations, is a source of particulate matter emissions. Agricultural sources vary both temporally and spatially due to daily and seasonal activities and inhomogeneous area sources. Conventional point sampling methods originally designed for regional, well mixed aerosols are challenged by the disrupted wind flow and by the small mobile source of the emission encountered in this study. Atmospheric lidar (LIght Detection And Ranging) technology provides a means to derive quantitative information of particulate spatial and temporal distribution. In situ point measurements of particulate physical and chemical properties …

The Relationship Between Energy Balance Understanding And Measures Of Wellness, Stephanie Fishel-Brown

All Dissertations

Much emphasis on the fight against obesity is placed on education and food labeling, yet very little research has been performed to measure how much people know about energy balance and the relationship of this knowledge to measures of wellness. The primary objective of this study was to determine if college students' (N = 262) performance on an energy balance questionnaire is associated with measures of wellness. Performance on the questionnaire as a whole was not significantly correlated (p > .05) with body mass index (BMI; r_s = .04), percent body fat (r_s = .05), waist to hip ratio …

Carnosine Content And Antioxidant Activity From Poultry Co-Products, Protein Meal And Stressed Poultry Tissues, Paljinder Manhiani

All Dissertations

Four separate studies were conducted to examine carnosine levels and associated antioxidant activity in poultry co-products, in rendered poultry protein meal, in tissues from stressed or non-stressed chickens. In the first study, carnosine was extracted from poultry co-products (head, liver, lungs, tail, gizzard, brain and heart). Liver contained the highest (102.29 mg/gm) level, while brain contained the lowest level of carnosine (0.95 mg/gm). Except brain, all tissue ultrafiltrates (20.87-39.57%) and reconstituted dry powders (5.66- 14.47%) showed thiobarbituric reactive acid species (TBARS) inhibition. Head ultrafiltrate and reconstituted dry powder showed maximum while gizzard showed the minimum metal chelating activity. Free radical …

Production And Characterization Of Novel Air Filtration Media, Elizabeth Skomra

All Dissertations

HEPA and ULPA filtration systems have proven to be an advantageous instrument in removing common contaminants from the air. However, an increased pressure drop due to the build-up of particulates on the filters results in its inevitable decrease in performance. Improving current filtration systems would include increasing collection efficiency all the while either maintaining or reducing the differential pressure drop in order to extend the life of the filter. One method of improving collection efficiency would be viable by increasing the amount of surface area within the filter media by glass fibers because of their inherent quality of being smaller …

The Development Of A Mesenchymal Stem Cell Based Biphasic Osteochondral Tissue Engineered Construct, Scott Maxson

All Dissertations

The ability of human articular cartilage to respond to injury is poor. Once cartilage damage has occurred, an irreversible degenerative process can occur and will often lead to osteoarthritis (OA). An estimated 26.9 million of U.S. adults are affected by OA. Osteochondral grafting is currently used to treat OA and osteochondral defects; however, complications can develop at the donor site and defect area. Osteochondral tissue engineering provides a potential treatment option and alternative to osteochondral grafting. The long term goal of this work is to develop a tissue engineered mesenchymal stem cell (MSC) based osteochondral construct to repair cartilage damage. …

Tertiary Level Students And The Mental Health Index (Mhi-5) In Ireland, Frank Houghton, Noreen Keane, Niamh Murphy, Sharon Houghton, Claire Dunne

Irish Journal of Applied Social Studies

An examination of student mental health was conducted using the five item Mental Health Index (MHI), a subscale of the widely used SF-36 (Short Form Health Survey). Results support the use of the MHI, which was found to be to be a valid and reliable measure of mental health in Irish third-level students. As anticipated, females reported significantly higher levels of symptoms than males on the MHI. It was also noted that final year students report significantly worse mental health than other students. Comparison with a general population mean for a corresponding age group indicate significantly lower mental health status …
