Old Dogs And New Tricks: Facilitating Implementation Of Contemporary Academic Technology With An Aging Teaching Population, Jack B. Hamlin Phd, Heather J. Leslie Phd

Learning Design Center: Staff Scholarship

Using a conversational approach, the authors address two fundamental dynamics of online education; engagement with students using online education technology and preparing “older” educators to use that technology. The authors present a discourse about the training of an older professor by a younger technologically savvy professor through the team-teaching of an online course called Facilitation Fundamentals. The professors redesigned the course with the goal of making it more engaging and authentic for adult learners. The redesign of the course is discussed as well as the teaching strategies used and technological hurdles the professors had to overcome. Finally, the professors reflect …

Establishment Of Wildflower Islands To Enhance Roadside Health And Aesthetics, Walter Schacht, Judy Wu-Smart

Nebraska Department of Transportation: Research Reports

Wildflowers are crucial in the ecological function of the low-input roadside plant communities in terms of water andnutrient cycling, nutrient inputs such as nitrogen, total plant canopy cover, stand longevity, and provision of habitat for numerous small animals. Further, wildflowers provide critical foraging and nesting resources for birds, insects, and other wildlife. Unfortunately, habitat loss from agricultural and urban development has led to rapid population declines in wild bees and other pollinators across the US, thereby jeopardizing not only food production but also the sustainability of our natural landscapes (Kearns & Inouye, 1997). One way to mitigate wild bee decline …

Using Blockchain Technology For The Organ Procurement And Transplant Network, Utsav Jain

Master's Theses

The organ donation system in the United States is centralized and difficult to audit by the general public. This centralized approach may lead to data integrity issues in the future. The Organ Procurement and Transplant Network (OPTN) was built and maintained by a non-governmental organization called the United Network for Organ Sharing (UNOS) under its proprietary UNet(SM) umbrella platform. This platform is made up of proprietary closed source software and does not provide the general public easy access to the organ transplant data for auditing. This study investigates the feasibility, challenges, and advantages of a blockchain-based OPTN.

High-Throughput Screening Of A Metagenomic Library Using A Novel E. Coli Chip For Discovery Of Antibiotic Resistance Genes, Richard Paul Manarin Tiongco

Master's Theses

The growing prevalence of antibiotic resistance is one of the greatest challenges facing humankind today. The Centers for Disease Control and Prevention (CDC) have estimated that about 2 million people in the US each year develop an infection caused by antibiotic-resistant bacteria, and about 23,000 people die. To combat this growing crisis, efforts geared toward the discovery of novel compounds, such as antimicrobial peptides (AMPs), have spurred. However, current approaches for identification of such compounds have proven to be costly, time-consuming and ineffective. This problem underscores the need for a new approach, one that is fundamentally different from traditional methods …

Electrical Characterization Of Blood Clots, William Mcgrath

Master's Theses

This work reports the use of dielectric spectroscopy to study blood and blood clots. A test setup was developed and electrode behavior was characterized with water and salt solutions. By measuring changes in electrical permittivity, trends differentiating clotting and non-clotting blood were identified. Non-clotting blood exhibited an increase in normalized permittivity at high frequencies that is credited to the sedimentation of red blood cells (RBCs) in static blood samples. Clotting blood was found to show a decrease in permittivity after some time at high frequencies. This is associated with the aggregation of red blood cells. Platelet rich plasma (PRP) and …

Non-Invasive Hyperglycemia Detection Using Ecg And Deep Learning, Renato Silveira Cordeiro

Master's Theses

Hyperglycemia is characterized by an elevated level of glucose in the blood. It is normally asymptomatic, except for an extremely high level, and thus a person can live in that state for years before the negative - sometimes irreversible - health impacts appear. Unexpected hyperglycemia can also be an indication of diabetes, a chronic disease that, when not treated, can lead to serious consequences, including limb amputations and even death. Therefore, identifying hyperglycemic state is important. The most common and direct way to measure a person’s glucose level is by directly assessing it from a blood sample by pricking a …

The data collected were analyzed to determine the fire behavior, specifically fire spread (direction and rate) and flame characteristics (length, height, and angle). During the first several minutes of the experiment, fire behavior was as expected with an upslope rate of spread at 0.1 m s-1 and flame lengths between 1 m and 4 m. …

Expression And Purification Of Snake Antivenom Peptide In Pichia Pastoris, Israel Juarez Contreras

Master's Theses

It has been shown that a peptide of the first 10-15 N-terminal amino acids of the lethal toxin neutralizing factor (LTNF) protein found in opossums (Didelphis spp.) holds promise as a low-cost therapy for snake envenomation. To date, the 11-mer has been expressed in E. coli and shown to neutralize snake venoms. However, possible endotoxin concerns warrant an investigation into other microbial hosts. The methylotrophic yeast, Pichia pastoris, shows promise as an alternative host. Active LTNF peptide was expressed and purified in P. pastoris. This was accomplished by subcloning a tandem repeat of the first 15 N-terminal amino acids of …

The Deformability Of Red Blood Cells In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (Me/Cfs), Brendan Robert Schmidt

Master's Theses

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disease that causes profound fatigue in its sufferers as well as loss of concentration, headaches, and sleep abnormalities. Unfortunately, the disease is poorly diagnosed, and etiology is not known. Although the ME/CFS patients do not show anemic readings, and their arterial partial pressure is normal, it is possible that their extreme post-exertional malaise stems from poor microvascular perfusion and oxygenation. Previous studies have indicated that the red blood cells (RBCs) in ME/CFS patients show evidence of oxidative damage. We hypothesized that the RBC deformability metrics can serve as a reliable biomarker of ME/CFS …

A Technique For Calculating Flexural Rigidity Of Nonlinear Systems, Chase Hartquist

Mechanical Engineering and Materials Science Independent Study

Faculty Adviser: Guy Genin

Geometric, kinematic, force, and material nonlinearity arise in manufactured products. Flexural rigidity, or relative stiffness of a beam, cannot be measured accurately for flexible, composite medical devices like catheters and sheaths using linear beam theory because they undergo high deformations when subject to relatively small loads. Surgeons depend on the relative stiffness of their catheters to determine the maneuverability of their devices. For neurovascular interventions, surgeons rely on stiffness to determine if their catheter can navigate arduous vasculature, especially around the aortic arch¹. Navigation has become increasingly difficult as surgeons have adopted the …

Ueb Parallel: Distributed Snow Accumulation And Melt Modeling Using Parallel Computing, Tseganeh Z. Gichamo, David G. Tarboton

Publications

The Utah Energy Balance (UEB) model supports gridded simulation of snow processes over a watershed. To enhance computational efficiency, we developed two parallel versions of the model, one using the Message Passing Interface (MPI) and the other using NVIDIA's CUDA code on Graphics Processing Unit (GPU). Evaluation of the speed-up and efficiency of the MPI version shows that the effect of input/output (IO) operations on the parallel model performance increases as the number of processor cores increases. As a result, although the computation kernel scales well with the number of cores, the efficiency of the parallel code as a whole …

Blind Algorithm Development For Peak To Average Power Ratio Reduction In Ofdm Systems Under Frequency Selective Channels, Kwame S. Ibwe

Tanzania Journal of Engineering and Technology (TJET)

One major drawback of orthogonal frequency division multiplexing (OFDM) system is peak to average power ratio (PAPR). This effect causes high power amplifier (HPA) to introduce intermodulation and out of band radiation as the signal goes through, thus degrades the performance of OFDM systems. This paper proposes blind algorithms which takes advantage of signal transformation technique and signal distortion technique. Simulation results show that at complementary cumulative distribution function (CCDF) level of 10-3, the proposed algorithm achieved 3.2 dB PAPR improvement compared to discrete Fourier transform with interleaved frequency division multiple access (DFT-IFDMA) based algorithm. The bit error rate (BER) …
