Wastewater Treatment Fatty Acids For Biodiesel Production, Zachary Christman Jan 2020

Wastewater Treatment Fatty Acids For Biodiesel Production, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Wastewater scum is the thick oily substance that floats on top of the primary and secondary tanks within a wastewater treatment plant. Scum has a 30% to 60% lipid content making it an excellent resource for the biodiesel industry. Also the use of scum would reduce the cost of current management practices such as landfill disposal or incineration. In this article there is an overview of lipid byproducts currently being produced at wastewater treatment plants today. This is followed by a presentation showing a full length process for turning wastewater scum into biodiesel raw material.


Population Demographics: Predictors Of The Relationship Between Alcohol Use Disorder And Major Depression, Mei Grace Behrendt Jan 2020

Population Demographics: Predictors Of The Relationship Between Alcohol Use Disorder And Major Depression, Mei Grace Behrendt

Honors Program: Senior Projects (Public)

This thesis examines both biological and social explanations of alcohol use disorder (AUD) and major depression (MD) through a thorough review of current literature. Using multiple logistic regression analyses exploring the sociodemographic and alcohol use factors that contribute to reporting of major depression symptoms with data from the 2017 National Survey on Drug Use and Health, this thesis demonstrates how there are health disparities that exist among different demographic populations. Specifically, certain demographic characteristics such as racial or ethnic identity, gender, and socioeconomic status may contribute to increased risk of developing and reporting episodes of lifetime and past year major …

Pharmaceutical Manufacturing In The 21st Century: Identification And Analysis Of Key Elements, Robert N. Mills

Honors Program: Senior Projects (Public)

The availability of quality pharmaceutical products impacts the lives of the global population on a daily basis. The importance of product availability and quality within pharmaceutical manufacturing requires that quality systems put into place are capable of accurately and robustly capturing the quality compliance, or lack thereof, of the various stages of production. This review intends to analyze current expert-recommended best practices within key elements of a pharmaceutical manufacturing quality control system and provide recommendations throughout. The quality elements discussed include Quality by Design method validation, necessary equipment determination, and equipment qualification, followed by documentation control and data flow.


Synthesis And Evaluation Of Nebraska Red Derivatives For Protein Labeling Studies, Lauren Lesiak Jan 2020

Synthesis And Evaluation Of Nebraska Red Derivatives For Protein Labeling Studies, Lauren Lesiak

Honors Program: Senior Projects (Public)

G protein-coupled receptors (GPCRs) play a vital role in cell signaling, and imaging the internalization of these proteins will allow for better understand of protein trafficking within the cell, as well as identification of potential drug targets. However, there is a need for further development of fluorescent protein labels that are able to effectively monitor GPCR internalization in the near-infrared (NIR) range. We recently described a series of NIR fluorophores in which a phosphinate functionality is inserted at the bridging position of the xanthene scaffold, called the Nebraska Red (NR) dye series. These dyes are attractive reagents for the imaging …

Public Health Entomology Certificate Preparation Course For Esa, Sylvia Kenmuir

Department of Entomology: Distance Master of Science Projects

My Master’s Project was to develop a preparation course for the Entomological Society of America (ESA) Public Health Entomology (PHE) Certificate. This is a new program for ESA. Unlike the Board Certified Entomologist (BCE) or Associate Certified Entomologist (ACE) programs which are certifications, the PHE is a standalone certificate in the area of public health. This certificate seeks to identify people who want to further demonstrate public health as an area of expertise. This course will be available to any qualified and approved person seeking to offer preparation course to assist people in preparing for the exam. Currently there is …


The Effect Of Wildlife Wellbeing On Environmental Concern, Laura Casne Jan 2020

The Effect Of Wildlife Wellbeing On Environmental Concern, Laura Casne

Department of Environmental Studies: Undergraduate Student Theses

Environmental campaigns have used animal imagery to push their initiatives for years, shocking viewers with images of human caused damage to change environmental behavior. The Royal Society for the Prevention of Cruelty to Animals (RSPCA), a nonprofit located in Britain released a statement that they responded to 5000 calls annually regarding litter and that the main victims were wildlife species (Litter and Animals | Rubbish and Animals - RSPCA, 2017). A previous study done by Schultz (2000) showed animals in different conditions (animals in nature and animals harmed in nature), with results indicated that those who viewed an image of …


Ecological Perspectives Of The Eastern Saline Wetlands Differ Between Visitors And Non-Visitors, Peter Janda Jan 2020

Ecological Perspectives Of The Eastern Saline Wetlands Differ Between Visitors And Non-Visitors, Peter Janda

Department of Environmental Studies: Undergraduate Student Theses

The Eastern Saline Wetlands of Nebraska can be found in both Lancaster and Saunders counties in Eastern Nebraska. Due to the wetlands’ important services in the areas of recreation, wildlife habitat, and flood control, it is necessary to know the extent to which these services are valued and used by residents of Lincoln . Past research completed in 2015 by the Lower Platte South NRD observed public opinions toward wetland restoration and preservation, finding that 46% of the public strongly support it, 35% mildly support it and 16% do not support it (Saline Wetlands Conservation Partnership, 2006).

The Changing Habitat And Decline Of Ring-Necked Pheasant Populations In Otoe County, Nebraska, Jacob T. Herman Jan 2020

The Changing Habitat And Decline Of Ring-Necked Pheasant Populations In Otoe County, Nebraska, Jacob T. Herman

Department of Environmental Studies: Undergraduate Student Theses

Since the early 20th century, wildlife conservation in Untied States has walked a fine line of growth and decline. The implementation of the Ring-Necked Pheasant in Nebraska has brought a wealth of tradition and revenue to the state across multiple generations. This thesis analyzes how habitat changes in Otoe County, Nebraska have affected the Ring-Necked Pheasant population, and what programs are in place to counteract the issue. To answer this question, the study compared five different aerial photos taken from Google Earth Pro and the county archives located in Hardin Hall at the University of Nebraska- Lincoln. The results of …


Incorporating Tallgrass Prairie Into Urban Environments, Daniel Hauschild Jan 2020

Incorporating Tallgrass Prairie Into Urban Environments, Daniel Hauschild

Department of Environmental Studies: Undergraduate Student Theses

As an agricultural state with a population poised to shift to primarily urban based, Nebraska is in the unique position of being able to decide how people live in modern cities. While the benefits of including green spaces in urban areas are well documented, evidence also suggests that increased biodiversity in these areas compounds those benefits. As such, incorporating elements of functioning natural ecosystems within urban areas can potentially create pockets of sustainable landscapes. Nebraska’s two largest population centers are located on land that was historically tallgrass prairie, an iconic landscape in American history and now almost entirely absent from …


Growth And Feeding Response In Python Regius In Ambient Temperature Vs. Hot-Spot, Mckenzie Martinez Jan 2020

Growth And Feeding Response In Python Regius In Ambient Temperature Vs. Hot-Spot, Mckenzie Martinez

Department of Environmental Studies: Undergraduate Student Theses

Python regius, also known as the ball python or the royal python, is one of the most popular reptiles in the pet trade and has been heavily imported, kept, and bred in captivity since 1976 (Toudonou 1). This species has adapted to life in captivity extremely well making it one of the most popular reptiles in the reptile trade. It is one of the first reptiles many reptile enthusiasts own. It is a frequently used species for educating the public in zoos and other facilities. Some of the main reasons that Python regius has maintained its popularity in the reptile …


The Effect Of Pictorial Signs On Recycling Rates, Christopher A. Sukstorf Jan 2020

The Effect Of Pictorial Signs On Recycling Rates, Christopher A. Sukstorf

Department of Environmental Studies: Undergraduate Student Theses

Recycling is a core way that college students can act altruistically. Many studies have been conducted to study how to increase the participation of recycling on college campuses, office buildings, and the like. This study focuses on the University Lutheran Chapel, a Christian church adjacent to the University of Nebraska – Lincoln. While the University of Nebraska – Lincoln has drastically improved recycling participation in recent years, the University Lutheran Chapel lags behind. Pictorial signs were used in an experiment to determine whether they improved recycling rates at The Chapel. Recycling rates at the University Lutheran Chapel were measured by …


Planning Urban Forests In A Changing Climate, Ethan Dudden Jan 2020

Planning Urban Forests In A Changing Climate, Ethan Dudden

Department of Environmental Studies: Undergraduate Student Theses

As the effects of negative effects of climate change are realized, urban forests a means to reduce the potential damage and adverse conditions in urban areas (Wolf, et al., 2020) (Livesley, McPherson, & Calfapietra, 2016) (Xiao & McPherson, 2002). Preserving these resources is becoming more difficult however, as the trees that make up urban landscapes become less adapted to current conditions with every passing year (Aitken, Yeaman, Holliday, Wang, & Sierra, 2008). Changes in climate and world systems also point to invasive pests becoming greater threats to urban forest resources with time (Tubby & Webber, 2010) (Amberger et al., 2017). …

Divergent Density Feedback Control Of Migratory Predator Recovery Following Sex-Biased Perturbations, Daisuke Goto, Martin J. Hamel, Mark A. Pegg, Jeremy J. Hammen, Matthew L. Rugg, Valery E. Forbes Jan 2020

Divergent Density Feedback Control Of Migratory Predator Recovery Following Sex-Biased Perturbations, Daisuke Goto, Martin J. Hamel, Mark A. Pegg, Jeremy J. Hammen, Matthew L. Rugg, Valery E. Forbes

School of Biological Sciences: Faculty Publications

Uncertainty in risks posed by emerging stressors such as synthetic hormones im-pedes conservation efforts for threatened vertebrate populations. Synthetic hor-mones often induce sex-biased perturbations in exposed animals by disrupting gonad development and early life-history stage transitions, potentially diminishing per capita reproductive output of depleted populations and, in turn, being manifest as Allee effects. We use a spatially explicit biophysical model to evaluate how sex-biased perturbation in life-history traits of individuals (maternal investment in egg production and male-skewed sex allocation in offspring) modulates density feedback control of year-class strength and recovery trajectories of a long-lived, migratory fish—shovelnose sturgeon (Scaphirhynchus platorynchus)—under spatially …


Is Perception Of Inability To Procreate A Temporal Phenomenon? A Longitudinal Exploration Of Changes And Determinants Among Women And Men Of Reproductive Age In Germany, Jasmin Passet-Wittig, Martin Bujard, Julia Mcquillan, Arthur L. Greil Jan 2020

Is Perception Of Inability To Procreate A Temporal Phenomenon? A Longitudinal Exploration Of Changes And Determinants Among Women And Men Of Reproductive Age In Germany, Jasmin Passet-Wittig, Martin Bujard, Julia Mcquillan, Arthur L. Greil

Department of Sociology: Faculty Publications

Continued postponement of births and increasing use of reproductive medicine enhance the relevance of infertility and related perceptions for fertility research. Fertility researchers tend to assume that an existing perception of inability to procreate is a stable trait among persons of reproductive age. This assumption is questionable from a life course perspective and has not been thoroughly investigated. Therefore we investigate the prevalence, stability, and correlates of perceived inability to procreate. We apply between-within logit models to annual panel data (2008-2015) to study variation in perceived inability to procreate within individuals over time and between individuals. We find that approximately …


Pregnancy Happiness: Implications Of Prior Loss And Pregnancy Intendedness, Stacy Tiemeyer, Karina Shreffler, Julia Mcquillan Jan 2020

Pregnancy Happiness: Implications Of Prior Loss And Pregnancy Intendedness, Stacy Tiemeyer, Karina Shreffler, Julia Mcquillan

Department of Sociology: Faculty Publications

Objective: This study aimed to examine the interaction between pregnancy loss and pregnancy intentions on women’s happiness about a subsequent pregnancy.

Background: Anxiety about prior loss persist for women, even during subsequent pregnancies. It is unclear from prior research, whether a prior pregnancy loss shapes attitudes towards and feelings about a subsequent birth.

Methods: Using data from the 2002–2013 National Survey of Family Growth (NSFG), we used logistic regression analyses to explore the implications of a prior pregnancy loss for happiness about a subsequent pregnancy that ends in a live birth. We compared births classified as on-time, mistimed, unwanted, and …


Nativity And Country Of Origin Variations In Life Expectancy With Functional Limitations Among Older Hispanics In The United States, Marc A. Garcia, Adriana M. Reyes, Catherine García, Chi-Tsun Chiu, Grecia Macias Jan 2020

Nativity And Country Of Origin Variations In Life Expectancy With Functional Limitations Among Older Hispanics In The United States, Marc A. Garcia, Adriana M. Reyes, Catherine García, Chi-Tsun Chiu, Grecia Macias

Department of Sociology: Faculty Publications

This study examined racial/ethnic, nativity, and country of origin differences in life expectancy with and without functional limitations among older adults in the United States. We used data from the National Health Interview Survey (1999–2015) to estimate Sullivan-based life tables of life expectancies with functional limitations and without functional limitations by sex for U.S.-born Mexicans, foreign-born Mexicans, U.S.-born Puerto Ricans, island-born Puerto Ricans, foreign-born Cubans, and U.S.-born Whites. We find that Latinos exhibit heterogeneous life expectancies with functional limitations. Among females, U.S.-born Mexicans, foreign-born Mexicans, and foreign-born Cubans spend significantly fewer years without functional limitations, whereas island-born Puerto Ricans spend …


Law And Same-Sex Couples’ Experiences Of Childbirth, Emily Kazyak, Emma Finken Jan 2020

Law And Same-Sex Couples’ Experiences Of Childbirth, Emily Kazyak, Emma Finken

Department of Sociology: Faculty Publications

In 2017, the Supreme Court ruled in Pavan v. Smith that states must allow married same-sex couples to both be listed as parents on their child’s birth certificate. Although the ruling garnered less media attention than the Court’s 2015 Obergefell v. Hodges decision on marriage, it nonetheless illustrates a significant issue pertinent to the families who are the focus of this chapter: lesbian same-sex couples who had children via donor insemination before 2015. Indeed, prior to this ruling, these couples faced an unequal legal climate insofar as only the biological mother could be listed on the birth certificate and thus …


Mutual Influence? Gender, Partner Pregnancy Desires, Fertility Intentions, And Birth Outcomes In U.S. Heterosexual Couples, Colleen M. Ray, Sela R. Harcey, Julia Mcquillan, Arthur L. Greil Jan 2020

Mutual Influence? Gender, Partner Pregnancy Desires, Fertility Intentions, And Birth Outcomes In U.S. Heterosexual Couples, Colleen M. Ray, Sela R. Harcey, Julia Mcquillan, Arthur L. Greil

Department of Sociology: Faculty Publications

Competing hypotheses exist with regard to how men’s and women’s pregnancy desires and intentions are associated with births among contemporary heterosexual couples. There are compelling cultural and structural reasons to support either the hypothesis that men’s desires and intentions (patriarchal) or that women’s desires and intentions (matriarchal) will have more influence, or that both partner’s desires and intentions will be associated with births (mutual influence). In addition, patterns of change are likely to differ for couples that have children at wave 1 compared to those who do not. Path analyses of the of heterosexual couples (n = 615) who completed …


Bioskills Guide: Development And National Validation Of A Tool For Interpreting The Vision And Change Core Competencies, Alexa W. Clemmons, Jerry Timbrook, Jon C. Herron, Alison J. Crowe Jan 2020

Bioskills Guide: Development And National Validation Of A Tool For Interpreting The Vision And Change Core Competencies, Alexa W. Clemmons, Jerry Timbrook, Jon C. Herron, Alison J. Crowe

Department of Sociology: Faculty Publications

To excel in modern science, technology, engineering, and mathematics careers, biology majors need a range of transferable skills, yet competency development is often a relatively underdeveloped facet of the undergraduate curriculum. We have elaborated the Vision and Change core competency framework into a resource called the BioSkills Guide, a set of measurable learning outcomes that can be more readily implemented by faculty. Following an iterative review process including more than 200 educators, we gathered evidence of the BioSkills Guide’s content validity using a national survey of more than 400 educators. Rates of respondent support were high (74.3–99.6%) across the 77 …


Male/Female Is Not Enough: Adding Measures Of Masculinity And Femininity To General Population Surveys, Jolene Smyth, Kristen Olson Jan 2020

Male/Female Is Not Enough: Adding Measures Of Masculinity And Femininity To General Population Surveys, Jolene Smyth, Kristen Olson

Department of Sociology: Faculty Publications

Survey research and sociological theory each provide insights into how and why people and groups act, think, and feel. Sociological theories identify what concepts are important for understanding and representing the social world. That is, sociological theories inform what to measure in surveys, and, to a certain extent, how to measure it. Survey research permits sociologists to carefully specify what is to be measured vis a vis sociological theory, setting surveys apart as a social research tool. It is this level of specification of concepts and measures that allow surveys to provide continued value at a time when “big data” …


Immunization Strategies In Networks With Missing Data, Samuel F. Rosenblatt, Jeffrey A. Smith, G. Robin Gauthier, Laurent Hébert-Dufresne Jan 2020

Immunization Strategies In Networks With Missing Data, Samuel F. Rosenblatt, Jeffrey A. Smith, G. Robin Gauthier, Laurent Hébert-Dufresne

Department of Sociology: Faculty Publications

Network-based intervention strategies can be effective and cost-efficient approaches to curtailing harmful contagions in myriad settings. As studied, these strategies are often impractical to implement, as they typically assume complete knowledge of the network structure, which is unusual in practice. In this paper, we investigate how different immunization strategies perform under realistic conditions—where the strategies are informed by partially- observed network data. Our results suggest that global immunization strategies, like degree immunization, are optimal in most cases; the exception is at very high levels of missing data, where stochastic strategies, like acquaintance immunization, begin to outstrip them in minimizing outbreaks. …


Competing Forces Of Withdrawal And Disease Avoidance In The Risk Networks Of People Who Inject Drugs, Elspeth Ready, Patrick Habecker, Roberto Abadie, Bilal Khan, Kirk Dombrowski Jan 2020

Competing Forces Of Withdrawal And Disease Avoidance In The Risk Networks Of People Who Inject Drugs, Elspeth Ready, Patrick Habecker, Roberto Abadie, Bilal Khan, Kirk Dombrowski

Department of Sociology: Faculty Publications

We analyze a network of needle-sharing ties among 117 people who inject drugs (PWID) in rural Puerto Rico, using exponential random graph modeling to examine whether network members engage in partner restriction to lower their risk of contracting HIV or hepatitis C (HCV), or in informed altruism to prevent others from contracting these infections. Although sharing of used syringes is a significant risk factor for transmission of these diseases among PWID, we find limited evidence for partner restriction or informed altruism in the network of reported needle-sharing ties. We find however that sharing of needles is strongly reciprocal, and individuals …


Soldiers To Scientists: Military Service, Gender, And Stem Degree Earning, Christina Steidl, Regina E. Werum, Sela R. Harcey, Jacob Absalon, Alice Millermacphee Jan 2020

Soldiers To Scientists: Military Service, Gender, And Stem Degree Earning, Christina Steidl, Regina E. Werum, Sela R. Harcey, Jacob Absalon, Alice Millermacphee

Department of Sociology: Faculty Publications

The authors use 2014–2018 data from the American Community Survey to answer two questions: To what extent is military service associated with higher rates of earning a bachelor’s degree in a science, technology, engineering, and mathematics (STEM) field (vs. a non-STEM field)? To what extent is this relationship gendered? The findings suggest that military service is associated with higher odds of completing a STEM degree and that this association is particularly strong for female veterans. Comparison across multiple STEM definitions suggests that military service does not simply channel women into traditionally female-dominated STEM fields. Instead, the findings show the biggest …

Paid Paternity Leave-Taking In The United States, Richard J. Petts, Chris Knoester, Qi Li Jan 2020

Paid Paternity Leave-Taking In The United States, Richard J. Petts, Chris Knoester, Qi Li

Department of Sociology: Faculty Publications

Surprisingly few studies have focused on paternity leave-taking in the United States. This study utilizes data from three national datasets to provide a comprehensive examination of the attitudes, practices, and predictors of paid paternity leave-taking in the US. Specifically, this study focuses on (a) describing attitudes toward fathers receiving a share of paid parental leave, (b) describing rates and lengths of paid paternity leave-taking, and (c) analyzing the extent to which economic capital, cultural capital, social capital, and father identities predict paternity leave-taking practices. The results indicate that most people support fathers receiving a share of paid parental leave in …


Remediating Soil For Successful Vegetation Establishment Along Nebraska Highways, Shad Mills, Martha Mamo, Walt Schacht, Humberto Blanco-Canqui Dec 2019

Remediating Soil For Successful Vegetation Establishment Along Nebraska Highways, Shad Mills, Martha Mamo, Walt Schacht, Humberto Blanco-Canqui

Nebraska Department of Transportation: Research Reports

Vegetation along roadsides is important to prevent soil erosion, provide habitat, and filter water running off the road. Vegetation close to the pavement along highways in Nebraska does not readily establish and persist. It is thought that the sodium and bulk density are the driving factors behind the lack of vegetation. After a construction project the shoulder is seeded into the compacted soil, and during winter salts can accumulate in the soil because of deicing agents being used. The purpose of our study was to determine if the sodium and bulk density are the driving factors of the vegetation cover. …
