Phr: Patient Health Record, Quinn Nelson 2018 University of Nebraska at Omaha

Phr: Patient Health Record, Quinn Nelson

Theses/Capstones/Creative Projects

The rapid development of information technology systems has expanded into multiple disciplines and results in systems that are limited by initial design and implementation: the Healthcare Information Technology (HIT) space is no different. The introduction of the Electronic Health Record (EHR) system has changed the way healthcare operates. Initial designs of these systems were focused on serving the needs of insurance companies and healthcare billing departments. Research shows that the design of EHR systems negatively impact provider-patient interactions and the care they receive. This capstone project capitalizes on the collaboration efforts between UNO and UNMC – by joining a research group ...


Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm 2018 University of Arkansas, Fayetteville

Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm

Animal Science Undergraduate Honors Theses

Abstract

Goats have a very long history with mankind and are commonly used as a nutritious red meat source around the world. The supply of goat meat in the United States does not meet the growing demand from ethnic consumers. This provides an economic opportunity in Arkansas agriculture because goats are uniquely adapted to the Ozark environment. There is a wide gap in caprine research which facilitated the conception of the study’s objectives to determine whether prepartum milk in goats showed a sudden rise in calcium levels within 24 to 48 hours of kidding and to ascertain whether an ...


Weather--Associated Triggers Of Nesting Activity Of Blanding’S Turtles (Emydoidea Blandingii) In Northeastern Illinois, Emma Buckardt 2018 SUNY College of Environmental Science and Forestry

Weather--Associated Triggers Of Nesting Activity Of Blanding’S Turtles (Emydoidea Blandingii) In Northeastern Illinois, Emma Buckardt

Honors Theses

Environmental triggers of nesting activities in turtles are poorly known, but important for guiding species protection efforts. Blanding’s Turtle (Emydoidea blandingii) is a species of concern throughout much of its range and is thought to prefer to nest on wet warm nights. Weather conditions during the nesting season were analyzed from 2013-2017 of a Blanding’s Turtle population located within the Lake Plain of northeastern Illinois and southeastern Wisconsin to identity climate conditions most associated with nesting activity. Peak nesting dates each year were associated with warmer mean temperature in the preceding months of March, April, and May such ...

Growth Characteristics Of Lactobacillus Wasatchensis And Its Detection And Enumeration Using Quantitative Polymerase Chain Reaction, Isaac Brockbank Bowen

All Graduate Theses and Dissertations

There are numerous challenges encountered during the manufacturing and storage of cheese by both the large-scale and artesian producers. One such challenge has been the formation of late gassy defect, which occurs when gas is produced by certain lactic acid bacteria found in the cheese block during storage and aging over a three month time period. Negative consequences of late gas production are slits and cracks in the cheese block and puffy cheese packaging, which cause significant financial losses for manufacturers along with poor consumer acceptance.

Lactobacillus wasatchensis is one such lactic acid bacterium shown to produce gas during cheese ...

Legacy Effects Of Long-Term Nitrogen Fertilizer Application On The Fate Of Nitrogen Fertilizer Inputs In Continuous Maize, Hanna J. Poffenbarger, John E. Sawyer, Daniel W. Barker, Daniel C. Olk, Johan Six, Michael J. Castellano 2018 Iowa State University

Legacy Effects Of Long-Term Nitrogen Fertilizer Application On The Fate Of Nitrogen Fertilizer Inputs In Continuous Maize, Hanna J. Poffenbarger, John E. Sawyer, Daniel W. Barker, Daniel C. Olk, Johan Six, Michael J. Castellano

Agronomy Publications

Nitrogen fertilizer management can impact soil organic C (SOC) stocks in cereal-based cropping systems by regulating crop residue inputs and decomposition rates. However, the impact of long-term N fertilizer management, and associated changes in SOC quantity and quality, on the fate of N fertilizer inputs is uncertain. Using two 15-year N fertilizer rate experiments on continuous maize (Zea mays L.) in Iowa, which have generated gradients of SOC, we evaluated the legacy effects of N fertilizer inputs on the fate of added N. Across the historical N fertilizer rates, which ranged from 0 to 269 kg N ha−1 yr ...


The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen 2018 Virginia Institute of Marine Science

The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen

Articles

Although both local processes (photosynthesis, respiration, grazing, and settling), and transport processes (advective transport and diffusive transport) significantly affect local phytoplankton dynamics, it is difficult to separate their contributions and to investigate the relative importance of each process to the local variability of phytoplankton biomass over different timescales. A method of using the transport rate is introduced to quantify the contribution of transport processes. By combining the time-varying transport rate and high-frequency observed chlorophyll a data, we can explicitly examine the impact of local and transport processes on phytoplankton biomass over a range of timescales from hourly to annually. For ...

Biochemistry and Molecular Medicine Faculty Publications

Dysregulation of multiple long non-coding RNAs (lncRNAs) was reported to play major roles in breast cancer (BC). Here we aimed to collect most of the relevant literature to assess the prognostic value of lncRNAs in BC. To this end, we systematically searched PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), and Wanfang to identify published articles on the associations of lncRNAs with clinicopathology and/or survival of BC. Via this searching, we identified 70 articles involving 9,307 BC patients and regarding 48 lncRNAs. The expression of 41 lncRNAs was related to one or more clinicopathological parameters of ...

Exploring Multiple Operating Scenarios To Identify Low-Cost, High Nitrate Removal Strategies For Electrically-Stimulated Woodchip Bioreactors, Ji-Yeow Law, Michelle L. Soupir, D. Raj Raman, Thomas Moorman

Agricultural and Biosystems Engineering Publications

Woodchip bioreactors are recognized as an effective best management practice in the Iowa Nutrient Reduction Strategy. This edge-of-field practice intercepts and removes NO3-N, thereby reducing the NO3-N concentration in tile drainage before being discharged into surface water. Actual NO3-N load reductions realized by woodchip bioreactors are impacted by bioreactor size, hydraulic retention time (HRT), and denitrification efficiency. A typical woodchip bioreactor in Iowa may have 0.07% bioreactor area with respect to treatment area, 4–8 h HRT, and 43% mean denitrification efficiency. Here, we explored the potential of using electrically stimulated woodchip bioreactors to achieve greater NO3-N removal, and ...


Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee 2018 The Graduate Center, City University of New York

Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee

All Dissertations, Theses, and Capstone Projects

Dystrophinopathy is a genetic disorder that results in the lack of or abnormal expression of the protein dystrophin. It is a disorder that alters cell structure and function, impacts the developing brain and brain function, presents with multi-domain cognitive deficits, and influences both mood and behavior. Cognitive impairments appear to be more localized to specific areas of functioning rather than a global deficit; however, deficits have been identified across multiple cognitive domains including language and aspects of executive functioning. A careful examination of the cognitive phenotype and its association to mutations affecting CNS isoforms is necessary to clarify the neuropsychological ...


Integration Of Bmp And Insulin/Igf-1 Signaling Regulates Multiple Homeostatic Functions In Caenorhabditis Elegans, James F. Clark 2018 The Graduate Center, City University of New York

Integration Of Bmp And Insulin/Igf-1 Signaling Regulates Multiple Homeostatic Functions In Caenorhabditis Elegans, James F. Clark

All Dissertations, Theses, and Capstone Projects

The maintenance of homeostatic functions is key to the survival and well-being of an organism. Regulation of homeostasis relies on varied inputs, both intrinsic and extrinsic, to potentiate a web of interconnected signaling relays. Insulin/IGF-1 signaling (IIS) is a well-known regulator of glucose and lipid metabolism, as well as having far reaching effects in other homeostatic mechanisms. On the other hand, bone morphogenetic protein (BMP), a member of the transforming growth factor beta signaling superfamily, is known for its role in differentiation and development, with only recent studies highlighting potential roles in metabolic homeostasis. Here we elucidate new functions ...


The Relationship Between Cognitive And Neural Bases Of Metamemory Judgments, Alexandra M. Gaynor 2018 The Graduate Center, City University of New York

The Relationship Between Cognitive And Neural Bases Of Metamemory Judgments, Alexandra M. Gaynor

All Dissertations, Theses, and Capstone Projects

Metamemory monitoring, the process of making subjective assessments of the status of one’s own memory, is crucial to guiding behavior and effective learning. Past cognitive research has shown that subjective confidence judgments are inferential in nature, and based on cues available at the time of the judgment. When confidence is based on cues that are related to objective memory performance, metamemory accuracy is high. However, past studies have shown that metamemory monitoring tends to be inaccurate because individuals base their confidence on information that is not predictive of memory success, such as the fluency with which items were encoded ...


The Relationship Of Male And Female Pastoralist Income With Household Food Security And Nutrition Status In Tanzania: Maasai, Sukuma, And Barabaig Ethnic Groups., Henriette Gitungwa 2018 University of Nebraska - Lincoln

The Relationship Of Male And Female Pastoralist Income With Household Food Security And Nutrition Status In Tanzania: Maasai, Sukuma, And Barabaig Ethnic Groups., Henriette Gitungwa

Dissertations and Theses in Agricultural Economics

Although previous work provides a significant baseline for understanding the impact of gender on household decision making and resource (i.e. income and food) allocation, there are gaps in evidence for important groups, including East African pastoralists. Previous authors have noted that pastoralists’ gender roles and relations appear to be resistant to change, potentially impeding household development. This paper attempts to assess the relationship between male and female pastoralists’ income control and household food security and nutritional status in Tanzania. We use three surveys: a household-level livestock health and economics survey, a household food security survey, and an individual woman-level ...


Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy 2018 The University of Southern Mississippi

Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration projects from ...

Synthesis And Immobilization Of Silver Nanoparticles On Aluminosilicate Nanotubes And Their Antibacterial Properties, G. Ipek Yucelen, Rachel E. Connell, Jessica R. Terbush, David J. Westenberg, Fatih Dogan

David J. Westenberg

A novel colloidal method is presented to synthesize silver nanoparticles on aluminosilicate nanotubes. The technique involves decomposition of AgNO3 solution to Ag nanoparticles in the presence of aluminosilicate nanotubes at room temperature without utilizing of reducing agents or any organic additives. Aluminosilicate nanotubes are shown to be capable of providing a unique chemical environment, not only for in situ conversion of Ag+ into Ag0, but also for stabilization and immobilization of Ag nanoparticles. The synthesis strategy described here could be implemented to obtain self-assembled nanoparticles on other single-walled metal oxide nanotubes for unique applications. Finally, we demonstrated that ...

The Engaged Microbiologist: Bringing The Microbiological Sciences To The K-12 Community, David J. Westenberg

David J. Westenberg

Exposing K-12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS), "engaging in practices that scientists and engineers actually use." This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM) can play a critical role. ASM encourages its members to ...
