Phosphorus Removal Using Titanium Dioxide Nanoparticles In Wastewater Treatment, Suyoung Choi Mr.

Theses and Dissertations (Comprehensive)

Due to eutrophication caused by nutrients such as phosphorus (P), local surface water near military garrisons and camps has been deteriorated for several years in the Republic of Korea. Thus, in order to remove excessive P in local fresh water, various size of titanium dioxide (TiO₂) were used.

In the first investigation, TiO₂ mixed bulk powder (particle size > 5µm) showed maximum P removal with pH dependence (higher pH shows lower P removal), that was approximately 27%. To determine adsorption isotherms, Langmuir and Freudlich models were used. The experimental data was better fit by a Langmuir model compared …

Dynamic Ocean Management Increases The Efficiency And Efficacy Of Fisheries Management, Daniel C. Dunn, Sara M. Maxwell, Andre M. Boustany, Patrick N. Halpin

Biological Sciences Faculty Publications

In response to the inherent dynamic nature of the oceans and continuing difficulty in managing ecosystem impacts of fisheries, interest in the concept of dynamic ocean management, or real-time management of ocean resources, has accelerated in the last several years. However, scientists have yet to quantitatively assess the efficiency of dynamic management over static management. Of particular interest is how scale influences effectiveness, both in terms of how it reflects underlying ecological processes and how this relates to potential efficiency gains. Here, we address the empirical evidence gap and further the ecological theory underpinning dynamic management. We illustrate, through the …

Tick-, Mosquito-, And Rodent-Bourne Parasite Sampling Designs For The National Ecological Observatory Network, Yuri Springer, David Hoekman, Pieter T.J. Johnson, Paul A. Duffy, Rebecca A. Hufft, Holly D. Gaff

Biological Sciences Faculty Publications

Parasites and pathogens are increasingly recognized as significant drivers of ecological and evolutionary change in natural ecosystems. Concurrently, transmission of infectious agents among human, livestock, and wildlife populations represents a growing threat to veterinary and human health. In light of these trends and the scarcity of long-term time series data on infection rates among vectors and reservoirs, the National Ecological Observatory Network (NEON) will collect measurements and samples of a suite of tick-, mosquito-, and rodent-borne parasites through a continental-scale surveillance program. Here, we describe the sampling designs for these efforts, highlighting sampling priorities, field and analytical methods, and the …

It identifies those species that are threatened with extinction at the global level and occur within the ECA region. This comprehensive assessment, which is the first of its kind in the ECA, aims to provide improved knowledge of species presence and extinction risk status for the purposes of guiding conservation actions and improved policies for these species …

Selective Mutation Accumulation: A Computational Model Of The Paternal Age Effect, Eoin C. Whelan, Alexander C. Nwala, Christopher Osgood, Stephan Olariu

Biological Sciences Faculty Publications

Motivation: As the mean age of parenthood grows, the effect of parental age on genetic disease and child health becomes ever more important. A number of autosomal dominant disorders show a dramatic paternal age effect due to selfish mutations: substitutions that grant spermatogonial stem cells (SSCs) a selective advantage in the testes of the father, but have a deleterious effect in offspring. In this paper we present a computational technique to model the SSC niche in order to examine the phenomenon and draw conclusions across different genes and disorders.

Results: We used a Markov chain to model the probabilities of …

Investigating Cholera Using An Sir Model With Age-Class Structure And Optimal Control, K. Renee Fister, Holly Gaff, Elsa Schaefer, Glenna Buford, Bryce C. Norris

Biological Sciences Faculty Publications

The use of systems of differential equations in mathematical modeling in conjunction with epidemiology continues to be an area of focused research. This paper briefly acquaints readers with epidemiology, cholera, and the need for effective control strategies; discusses cholera dynamics through a variation on the SIR epidemiological model in which two separate age classes exist in a population; finds the numeric value for R₀ to be approximately 1.54 using estimated parameters for Bangladesh; and employs an optimal control resulting in a suggestion that a protection control be implemented at the end of the monsoon season.

What Is The Effect Of Mandatory Pasteurisation On The Biogas Transformation Of Solid Slaughterhouse Wastes?, Niamh Power, Aidan Ware

Publications

The effect of mandatory pasteurisation on Category 3 offals, according to the Animal By-Products Regulation (ABPR 1069/2009/EC), was determined using Biochemical Methane Potential (BMP) assays as well as kinetic and statistical analysis. Pasteurised and unpasteurised offals sampled from cattle, pig and chicken slaughterhouses were characterised and their specific methane yields (SMYs) and their bioavailability was assessed. The resultant SMYs were high (465–650 mLCH₄ gVS⁻¹) with no statistically significant increase in methane production identified due to pasteurisation. However, the kinetics of the biogas transformation processes highlighted increased bioavailability of the organics due to pasteurisation. This was brought to …

Geospatial Approaches To Support Pelagic Conservation Planning And Adaptive Management, L. M. Wedding, Sara M. Maxwell, D. Hyrenbach, D. C. Dunn, J. J. Roberts, D. Briscoe, E. Hines, P. N. Halpin

Biological Sciences Faculty Publications

Place-based management in the open ocean faces unique challenges in delineating boundaries around temporally and spatially dynamic systems that span broad geographic scales and multiple management jurisdictions, especially in the 'high seas'. Geospatial technologies are critical for the successful design of pelagic conservation areas, because they provide information on the spatially and temporally dynamic oceanographic features responsible for driving species distribution and abundance in the open ocean, the movements of protected species, and the spatial patterns of distribution of potential threats. Nevertheless, there are major challenges to implementing these geospatial approaches in the open ocean. This Theme Section seeks to …

Computing Closed Forms For The Convergent Series $\Displaystyle\Sum_{N \In \Mathbb{Z}}\Frac{1}{(N^3+Bn^2+Cn+D)^K}$, Gagandeep K. Virk

Theses and Dissertations (Comprehensive)

In this thesis we discuss the various approaches that will be taken to evaluate and find a finite closed form for the sum $$\sum_{n \in \mathbb{Z}} \frac{1}{(n^3+Bn^2+Cn+D)^k}$$ where $B, C, D \in \mathbb{C}$ and $k$ is a positive integer. We begin this thesis by studying the cubic equations and discussing briefly various methods of finding their roots. Cardano's method (1545) for finding the roots of cubic polynomials is explored in detail as this method is used in later parts of the thesis to make calculations while evaluating the sums. Various tools and techniques from Fourier analysis are reviewed for these …

Working Towards The Welfare Of Our Children: An Argument For A Rebuttable Presumption Against Awarding Abusers Custody And Other Non-Legislative Proposals, Sapna Kishnani

Cardozo Journal of Equal Rights & Social Justice

The note examines the intersection of domestic violence and child custody determinations, highlighting the challenges faced by victims and the legal system in balancing the best interests of the child with the risks posed by abusive parents. It critiques the discretionary nature of the "best interests of the child" standard and proposes adopting Delaware’s rebuttable presumption against granting custody to perpetrators of domestic violence, while retaining New York’s preponderance of evidence standard. The analysis emphasizes the need for systematic approaches to child testimony and mediation to protect children’s well-being and ensure just outcomes.

Valloppilly, Yunlong Jin, Cai-Zhuang Wang, Kai-Ming Ho, David J. Sellmyer

Nebraska Center for Materials and Nanoscience: Faculty Publications

We report the fabrication of a set of new rare-earth-free magnetic compounds, which form the Fe₃Co₃Ti₂-type hexagonal structure with P-6m2 symmetry. Neutron powder diffraction shows a significant Fe/Co anti-site mixing in the Fe₃Co₃Ti₂ structure, which has a strong effect on the magnetocrystalline anisotropy as revealed by first-principle calculations. Increasing substitution of Fe atoms for Co in the Fe₃Co₃Ti₂ lattice leads to the formation of Fe₄Co₂Ti₂ , Fe₅CoTi, and Fe₆Ti₂ with significantly improved …

Contextual Experiences Of Overseas Trained Teachers Before And After Obtaining A Teaching Position In A Public Secondary School Of Western Australia And South Australia In Reference To Their Cultural Perspectives, Sushmita Datta Roy

Theses

The focus of this research was an exploration of the experiences of overseas trained teachers in the public secondary schools of Western Australia and South Australia, in reference to their cultural perspectives. Due to ongoing teacher shortage in the Australian public secondary schools (Weldon, 2015) many overseas trained teachers opt to migrate to Australia in the hope of establishing a new teaching career in the country. In the process, overseas trained teachers often undergo a range of contextual experiences, some that are challenging and some rewarding. It becomes meaningful, therefore, to explore the contextual experiences of overseas trained teachers and …

Evaluation Of Treatment For High Cholesterol And Prevention Of Cardiovascular Disease In Primary Care, Cristina Bolin

DNP Projects

Background Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death in the United States and more than 610,000 people die every year from ASCVD related causes such as myocardial infarction (MI) or stroke. High cholesterol is one of the leading modifiable risk factors for prevention of ASCVD events. The 2013 American College of Cardiology/American Heart Association guidelines recommend treatment of high cholesterol as primary prevention for ASCVD in adults by lifestyle changes, CV risk estimation with an ASCVD calculator, and intensity dosing of statin medication. Effective strategies to support these recommendation exist in the clinical practice guidelines but evidence …

Toxicity Of Engineered Nanomaterials To Plant Growth Promoting Rhizobacteria, Ricky W. Lewis

Theses and Dissertations--Plant and Soil Sciences

Engineered nanomaterials (ENMs) have become ubiquitous in consumer products and industrial applications, and consequently the environment. Much of the environmentally released ENMs are expected to enter terrestrial ecosystems via land application of nano-enriched biosolids to agricultural fields. Among the organisms most likely to encounter nano-enriched biosolids are the key soil bacteria known as plant growth promoting rhizobacteria (PGPR). I reviewed what is known concerning the toxicological effects of ENMs to PGPR and observed the need for high-throughput methods to evaluate lethal and sublethal toxic responses of aerobic microbes. I addressed this issue by developing high-throughput microplate assays which allowed me …

The Worm’S Eye View Of Community Ecology, Tavis K. Anderson, Michael V. K. Sukhdeo

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The study of parasites in the context of community level organization, either as parasites embedded within host communities, or as parasite communities themselves, is now quite prevalent in parasitology and ecology today. However, this was not always the case. In terms of publications, there was almost no consideration of parasite interactions at the community level for most of the first half of the last century. Papers in The Journal of Parasitology by Clark Read (1951) and John Holmes (1961) were the defining contributions to the beginning of the field, and the ideas elaborated by these two parasitologists still inspire current …

Fruits of saw palmetto (Serenoa repens) provide crucial, high-quality resources to wildlife while providing a matrix for many southeastern US ecosystems. As a foundation species, saw palmetto plays a major role in structuring fire-maintained plant communities. Often living on nutrient-poor soil conditions, the thick leaves of saw palmetto are long lived, up to 2.8 years in shaded sand pine scrub.

The Owl Sensor: A Smart Nanostructure For Single Nucleotide Variation Analysis, Rebekah Karadeema

Electronic Theses and Dissertations

Analysis of single nucleotide variations (SNVs) in DNA and RNA sequences is extensively used in healthcare for detection of genetic mutations and analysis of drug resistant pathogens. Here we developed a nucleic acid sensor able to differentiate between a fully matched analyte and one with a SNV in a wide temperature range of 5°C-32°C. The sensor, dubbed here the 'Owl Sensor' due to the complex's resemblance to owl eyes, utilizes recent developments in DNA nanotechnology and synthetic biology to self-assemble a fluorescent DNA nanostructure called a Double Crossover, or DX Tile, capable of differentiating SNVs in a large temperature range, …

Integrating Computational Modeling Modules Into Undergraduate Materials Science And Engineering Education, Lan (Samantha) Li

Materials Science and Engineering Faculty Publications and Presentations

To meet national workforce need, we integrated computational modeling training into undergraduate materials science and engineering (MSE) courses, including Thermodynamics, and Structure of Materials. We also flipped the courses, requiring students to self-study topics outside the class. In the class, the instructors focused on demonstrating real-world materials problems and guiding the students to solve the problems using different computational modeling techniques. Learning the computational modeling concepts within a short period of time was challenging to the students. Another challenge was that the students had various STEM backgrounds, such as MSE, mechanical engineering, and physics. In order to foster student learning, …

Celestial Sources For Random Number Generation, Erin Chapman, Jerina Grewar, Tim Natusch

Australian Information Security Management Conference

In this paper, we present an alternative method of gathering seed data for random number generation (RNG) in cryptographic applications. Our proposed method utilises the inherent randomness of signal data from celestial sources in radio astronomy to provide seeds for RNG. The data sets were collected from two separate celestial sources, and run through the SHA-256 algorithm to deskew the data and produce random numbers with a uniform distribution. The resulting data sets pass all tests in the NIST Statistical Test Suite for random data, with a mean of 98.9% of the 512 total bitstreams from the two sources passing …

An Analysis Of Chosen Alarm Code Pin Numbers & Their Weakness Against A Modified Brute Force Attack, Alastair Nisbet, Maria Kim

Australian Information Security Management Conference

Home and commercial alarms are an integral physical security measure that have become so commonplace that little thought is given to the security that they may or may not provide. Whilst the focus has shifted from physical security in the past to cyber security in the present, physical security for protecting assets may be just as important for many business organisations. This research looks at 700 genuine alarm PIN codes chosen by users to arm and disarm alarm systems in a commercial environment. A comparison is made with a study of millions of PIN numbers unrelated to alarms to compare …
