Male Remating Success And The Frequency Of Copulatory Plugs In The Green Lynx Spider Peucetia Viridans (Araneae, Oxyopidae), Martina G. Ramirez, Angelik C. Achekian, Catherine R. Coverley, Rachel M. Pierce, Sarah S. Eiman, Melissa M. Wetkowski

Biology Faculty Works

Peucetia viridans males were allowed to mate with three virgin females and most matings resulted in live spiderlings, even when males lacked palpal paracymbial processes. Among females, the presence of copulatory plugs was inconsistent, and when present, their condition was not uniform; broken-off male paracymbia were often found in epigynal orifices. There was no size effect in a male’s ability to completely plug a female’s genital orifices, as well as no significant change in the pattern of plug production over consecutive mating trials. Among mated, field-collected females, the presence of plugs and paracymbia was variable, with females from some sites …

Substrate Specificity Of The Tim22 Mitochondrial Import Pathway Revealed With Small Molecule Inhibitor Of Protein Translocation, Deepa V. Dabir

Biology Faculty Works

The TIM22 protein import pathway mediates the import of membrane proteins into the mitochondrial inner membrane and consists of two intermembrane space chaperone complexes, the Tim9-Tim10 and Tim8-Tim13 complexes. To facilitate mechanistic studies, we developed a chemical-genetic approach to identify small molecule agonists that caused lethality to a tim10-1 yeast mutant at the permissive temperature. One molecule, MitoBloCK-1, attenuated the import of the carrier proteins including the ADP/ATP and phosphate carriers, but not proteins that used the TIM23 or the Mia40/ Erv1 translocation pathways. MitoBloCK-1 impeded binding of the Tim9-Tim10 complex to the substrate during an early stage of translocation, …

Patch Selection By Wintering White-Tailed Deer : Consequences For Eastern Hemlock Regeneration At Local And Landscape Scales, Jill Christine Witt

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

Tsuga canadensis (eastern hemlock) is a highly shade-tolerant, late-successional, and long-lived conifer species found throughout eastern North America. It is most often found in pure or nearly pure stands, because highly acidic and nutrient poor forest floor conditions are thought to favor T. canadensis regeneration while simultaneously limiting the establishment of some hardwood species with greater nutrient requirements. Once a common species, T. canadensis is currently experiencing widescale declines across its range. The hemlock woolly adelgid (Adelges tsugae) is decimating the population across its eastern distribution. Across the Upper Great Lakes region, where the adelgid is currently being …

Use Of A 3d Perfusion Bioreactor With Osteoblasts And Osteoblast/Endothelial Cell Co-Cultures To Improve Tissue-Engineered Bone, Matthew J. Barron

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

The delivery of oxygen, nutrients, and the removal of waste are essential for cellular survival. Culture systems for 3D bone tissue engineering have addressed this issue by utilizing perfusion flow bioreactors that stimulate osteogenic activity through the delivery of oxygen and nutrients by low-shear fluid flow. It is also well established that bone responds to mechanical stimulation, but may desensitize under continuous loading. While perfusion flow and mechanical stimulation are used to increase cellular survival in vitro, 3D tissue-engineered constructs face additional limitations upon in vivo implantation. As it requires significant amounts of time for vascular infiltration by the host, …

Influence Of Traumatic Impaction And Pathological Loading On Knee Menisci, Megan Leigh Killian

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

Nearly half of the US population faces the risk of developing knee osteoarthritis (OA). Both in vitro and in vivo studies can aid in a better understanding of the etiology, progression, and advancement of this debilitating disorder. The knee menisci are fibrocartilagenous structures that aid in the distribution of load, attenuation of shock, alignment and lubrication of the knee. Little is known about the biochemical and morphological changes associated with knee menisci following altered loading and traumatic impaction, and investigations are needed to further elucidate how degradation of this soft tissue advances over time. The biochemical response of porcine meniscal …

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 …

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. …

Enrollment for Management Information Systems (MIS) majors has been declining since shortly after the turn of the century. The purpose of this document is to identify the indisputable benefits of maintaining a strong MIS degree program in the School of Business & Economics at Michigan Tech. We begin by clarifying what is meant by MIS and defining the discipline, reviewing the history of MIS in the SBE (e.g. average nearly 20% female majors in this particular STEM field), summarizing an analysis of our degree program (i.e. SWOT analysis), and outlining a plan to improve the number of MIS majors within …

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 …

Is The Special Purpose Vehicles Act Responsible For The Decline In Npl Ratios?, Stephanie L. Chan, Andrew Adrian Y. Pua

DLSU Business & Economics Review

This study aimed to determine if the SPV Act was actually responsible for the marked decline in NPL ratios this past four years. Using aggregated data for the entire Philippine Banking System, segregated according to type of bank, results suggest that the SPV Act was not responsible for the decline in the NPL ratios but may be attributed to a downward trend in the loan to asset ratio where values are getting closer to the interval for which NPL ratios are at a minimum, economic sluggishness as measured by deviations from the long run trend of macroeconomic variables, and seasonal …

A Comparative Analysis Of The Entrepreneurial Styles Of Second, Third, And Fourth Generation Overseas Chinese And Filipinos In The Philippines, Gerley Q. Po

DLSU Business & Economics Review

This study used the multiple case study research approach and presents a comparative analysis of the similarities and differences in entrepreneurship styles among second, third and fourth generation overseas Chinese and Filipinos in the Philippines. Specifically, it aimed to compare the entrepreneurs’ entrepreneurial characteristics, leadership styles, and value orientation. The results indicate that the two groups are heterogeneous even though they operate business in the same country. However, slowly, the influence of Filipino culture is seen in the fourth generation overseas Chinese. The study hopes to provide new generation of entrepreneurs insights on entrepreneurial styles that need to change to …

Nigeria’S Debt Overhang (1960-2005): A Critical Revisit, Solomon A. Adebola

DLSU Business & Economics Review

A general global trend up to the 1980’s has been for nations to rely substantially on external loans and aids for economic sustenance and technological development. This is particularly true for less developed countries (LDC). Unfortunately for these LDCs, their debts have gone beyond the countries’ capacity to repay. The debts have, for many such developing countries, been on a perpetual geometrical increase. Such countries have ended up with a debt overhang, with its detrimental impacts on the countries’ economic growth and social development. This research note gives a treatise on the theoretical framework of a debt overhang, and a …

Arizona's Notice Of Claim Statute: Guidance On Clearing This Procedural Hurdle And Suggestions For Its Improvement, Dawinder S. Sidhu

Faculty Scholarship

The Arizona Constitution empowers the legislature to establish rules for how and under what circumstances the State may be sued. Pursuant to this constitutional authority, the Arizona State Legislature enacted Arizona Revised Statutes Section 12-821.01, which requires those with claims against an Arizona public entity or employee to file notice of the claims prior to the initiation of legal action. This procedural prerequisite to initiate a suit may be prudent as a matter of public policy. In practice, however, the state courts have been unable to issue reliable decisions with respect to the statute’s requirements. The state courts’ evolving understanding …

The Future Of The United States Commission On Civil Rights, Dawinder S. Sidhu

Faculty Scholarship

In The Future of the U.S. Commission on Civil Rights, Professors Lisa Crooms and Dawinder Sidhu discuss the potential for expanding the mandate of the Commission. Professor Crooms opens by noting that suggestions to expand the Commission’s mandate to include human rights have been around for decades, and argues that such ideas are still worth adopting. She comments that the Commission would have to engage in extensive fact-finding in order to justify such an expansion. Professor Crooms raises further concerns over manipulation of the appointment process for commissioners, but that such manipulation has not necessarily jeopardized the Commission’s role. Indeed, …

Perspectives Of Fitness And Health In College Men And Women, Jennifer J. Waldron, Rodney B. Dieser

Faculty Publications

Because many college students engage in low levels of physical activity, the current study used a qualitative framework to interview 11 college students to examine the meaning physically active college students assign to the practice of fitness and health. Students discussed the importance of healthy eating, but that it was difficult to accomplish at college. Additionally, students intertwined health and fitness with physical appearance and attractiveness. In particular, the media shaped many of their perceptions of health and fitness. Implications of these findings to policy making in higher education, in particular wellness programming, are highlighted.
