Experimental Investigation Of Turbulent Flow Induced By New-Generation Wind Fences With Multi-Scale Fractal Structure, Sarah M. Mcclure

ETD Archive

Understanding and controlling atmospheric boundary-layer flows with engineered structures, such as porous wind fences or windbreaks, has been of great interest to the fluid mechanics and wind engineering community. Previous studies found that the regular mono-scale grid fence of 50% porosity and a bottom gap of 10% of the fence height are considered to be optimal over a flat surface. Significant differences in turbulent flow structure have recently been noted behind multi-scale fractal wind fences, even with the same porosity. In this study, wind-tunnel tests on the turbulent flow and the turbulence kinetic energy transport of 1D and 2D multi-scale …

Profiling Cell Surface Sialylation And Desialylation Dynamics Of Immune Cells, Dan Wang

ETD Archive

Sialic acids (SAs) are a diverse family of naturally occurring 2-keto-3-deoxy-nononic acids that are involved in a wide range of biological processes, including early fetal development, cellular recognition, and utilization by microbes. While it is clear that cell surface SAs are highly involved in the immune system, the sialylation status of individual immune cells and functions are still unknown. In this study, I combined the newly developed LC-MS/MS methods with flow cytometry and confocal microscopy to systematically study the sialylation and desialylation dynamics of macrophages at different conditions.

First, I developed an accurate LC-MS/MS method to quantify free SA in …

A simulation of this model was created based on estimated parameters for the model from historical data. This thesis investigated the estimation of glucose concentration, insulin concentration, and effect of active …

Organizational And Systems Factors Leading To Systems Integration Success After Merger And Acquisition, Monika Glazar-Stavnicky

ETD Archive

Mergers and acquisitions (M&A) are a common technique used by companies to grow and enter new markets. The success rate of these transactions continues to be less than desired. Information Systems (IS) have been proven to be a key component influencing the success of mergers. While numerous factors have been found to lead to systems integration success, the studies have not analyzed the fit that is required when two organizations and systems are joined. This research focuses on the match between organizational variables of competencies and processes of two merging companies, as well as the match between systems variables of …

The Role Of Rnase L In Type I Diabetes And Development Of Quantitative Lc-Ms/Ms Methods For The Pharmacological Studies Of Anti-Cancer Drug Candidates, Chun Zeng

ETD Archive

PROJECT I: The cause of type I diabetes continues to be a focus of investigation. In this study, we found that 2-5A dependent RNase L (RNase L), an IFN-a-inducible enzyme that functions in IFN action against viruses and cell proliferation, played an important role in dsRNA-induced onset of type I diabetes. By using RNase L deficient RIP-B7.1 mice which are more vulnerable to environmental harmful factors such as viral infection, we demonstrated that deficiency of RNase L in mice resulted in a significant delay of diabetes onset induced by polyinosinic:polycytidylic acid (poly I:C), a type of dsRNA, and streptozotocin (STZ). …

A Simulation And Experimental Study Of Active Disturbance Rejection For Industrial Pressure Control, Xiaoxu Li

ETD Archive

The quality of control loop is very important in hydraulic machineries, where pressure must be accurately regulated in the presence of various disturbances. Proportional-Integral-Derivative (PID) control has dominated the industry for a long time and it is by far the most popular general purpose controller for pressure control. The purpose of this study is to conduct a simulation and experimental study comparing PID with an emerging new technology, namely active disturbance rejection control (ADRC). For the purpose of this study, an experimental testbed similar to those used in industry settings is used; its mathematic model is derived and used in …

The Behavior Of Simply Supported Plates Under Extreme Shear Loading, Mhd Ammar Hafez

ETD Archive

Steel plates are planar structural elements with one dimension significantly smaller than the others. These elements may fail due to either material yielding or buckling. Buckling is a sudden failure mode, which is not desirable in structural engineering applications. Buckling is called an “elastic buckling” when it happens before material yielding, and is termed as “plastic buckling” if it happens after material yielding. The focus of this thesis is on shear plates, which are plates that are primarily subjected to shear loads. Several studies were conducted to increase the elastic buckling capacity of plates by adding stiffeners to plates. However, …

Coastal Development And Precipitation Drive Pathogen Flow From Land To Sea: Evidence From A Toxoplasma Gondii And Felid Host System, Elizabeth Vanwormer, Tim E. Carpenter, Purnendu Singh, Karen Shapiro, Wesley W. Wallender, Patricia A. Conrad, John L. Largier, Marco P. Maneta, Jonna A. K. Mazet

School of Natural Resources: Faculty Publications

Rapidly developing coastal regions face consequences of land use and climate change including flooding and increased sediment, nutrient, and chemical runoff, but these forces may also enhance pathogen runoff, which threatens human, animal, and ecosystem health. Using the zoonotic parasite Toxoplasma gondii in California, USA as a model for coastal pathogen pollution, we examine the spatial distribution of parasite runoff and the impacts of precipitation and development on projected pathogen delivery to the ocean. Oocysts, the extremely hardy free-living environmental stage of T. gondii shed in faeces of domestic and wild felids, are carried to the ocean by freshwater runoff. …

Aptitude And Trait Predictors Of Manned And Unmanned Aircraft Pilot Job Performance, Laura Barron, Thomas R. Carretta, Mark R. Rose

United States Air Force: Publications

Previous research has shown that the same aptitude and trait measures that predict success in US Air Force (USAF) manned aircraft pilot training predict remotely-piloted aircraft (RPA) pilot training outcomes with generally similar levels of validity (Carretta, 2013; Rose, Barron, Carretta, Arnold, & Howse, 2014). However, because USAF RPA pilots initially train in manned aircraft, validation of aptitude and traits predicative of RPA pilot success has thus far been limited to RPA pilot training outcomes that actually require manned flight. Hence, thus far there has been no basis for determining the aptitudes and traits predictive of success in environments in …

Memory Forensic Data Recovery Utilising Ram Cooling Methods, Kedar Gupta, Alastair Nisbet

Australian Digital Forensics Conference

Forensic investigations of digital devices is generally conducted on a seized device in a secure environment. This usually necessitates powering down the device and taking an image of the hard drive or semi-permanent storage in the case of solid state technology. Guidelines for forensic investigations of computers advise that the computer should be shut down by removing the power supply and thereby maintaining the hard disk in the state it was in whilst running. However, valuable forensic evidence often exists in the volatile memory which is lost when this process is followed. The issues of locked accounts on running computers …

Climate-Relevant Land Use And Land Cover Change Policies, Rezaul Mahmood, Roger A. Pielke Sr., Clive Mcalpine

High Plains Regional Climate Center: Staff Publications

Both observational and modeling studies clearly demonstrate that land-use and land-cover change (LULCC) play an important biogeophysical and biogeochemical role in the climate system from the landscape to regional and even continental scales. Without comprehensively considering these impacts, an adequate response to the threats posed by human intervention into the climate system will not be adequate. Public policy plays an important role in shaping local- to national-scale land-use practices. An array of national policies has been developed to influence the nature and spatial extent of LULCC. Observational evidence suggests that these policies, in addition to international trade treaties and protocols, …

Combining Body Mass And Shape Indices In Clinical Practice, Jesse C. Krakauer, Nir Y. Krakauer

Publications and Research

We present preliminary clinical experience with combined consideration of the commonly used BMI (body mass index) and the newly developed ABSI (a body shape index) using a point of care anthropometric calculator for comparisons of index values and associated relative risks to population normals. In a series of 282 patients, BMI and ABSI were close to being independently distributed, supporting the value of considering both indices. Three selected cases illustrate scenarios where assessment of ABSI together with BMI could inform patient care and counseling. These data suggest that combined assessment of BMI and ABSI may prove useful in clinical practice.

Eradicating Mass Spectrometric Glycan Rearrangement By Utilizing Free Radicals, Nikunj Desai, Daniel A. Thomas, Jungeun Lee, Jinshan Gao, Jesse L. Beauchamp

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Mass spectrometric glycan rearrangement is problematic because it provides misleading structural information. Here we report on a new reagent, a methylated free radical activated glycan sequencing reagent (Me-FRAGS), which combines a free radical precursor with a methylated pyridine moiety that can be coupled to the reducing terminus of glycans. The collisional activation of Me-FRAGS-derivatized glycans generates a nascent free radical that concurrently induces abundant glycosidic bond and cross-ring cleavage without the need for subsequent activation. The product ions resulting from glycan rearrangement, including internal residue loss and multiple external residue losses, are precluded. Glycan structures can be easily assembled and …

Technology Decisions In New Product Development, Amir Sanayei

Wayne State University Dissertations

Selecting the right technology is one of the most important and challenging decisions in new product development (NPD) process that can greatly affect all downstream design activities which have a great impact on product success in the market place. Although new technologies may bring more competitive advantage by offering higher performance to price, they also make the NPD process more risky and challenging. We model the technology selection problem of a firm that is defining its new product in the presence of the technology uncertainty. At each review stage, firm has the options: select and commit to any technology alternatives …
