Liquid Sorption Properties And Structural Changes Of Metal-Organic Frameworks Of Cobalt Nitrate And 4,4'-Bipyridine, Kathryn Mauger-Sonnek

Dissertations and Theses @ UNI

Metal-organic frameworks consist of metal ions connected by organic ligands. When the metal ions and organic ligands link together in the right geometry, polymeric and infinite 1D chains or 2D and 3D networks are formed. Porous metal-organic frameworks were synthesized from the organic ligand 4,4′-bipyridine (bpy) and cobalt(II) nitrate. The metal-organic frameworks synthesized in this study grew into both a previously known 2D bilayer structure, [Co2(bpy)3(NO3)4]n, and a new, orange 1D chain structure, [Co(bpy)NO3)2(H2O)2]n, within ethanol. It was found that the presence of water was the main factor of causing formation of the orange 1D chain crystals. Drying the orange …

Desulfotomaculum Dissimilatory Reduction Of Iron (Iii), Jim Elric

Dissertations and Theses @ UNI

Excess plant nutrient, often from agricultural runoff, can cause uncontrolled algal growth that leads to eutrophic conditions in a water body. Desulfotomaculum sp. reduction of ferric ions to ferrous ions can aid in reduction of excess phosphate in a water body. This bacterium may use iron mine tailings as an inexpensive source of iron ions that can aid in elimination of excess nutrient load such as phosphates. As part of a remediation plan Desulfotomaculum sp. reduction of ferric ions can help restore and maintain a healthy aquatic ecosystem. The biochemical pathway of iron reduction by Desulfotomaculum sp. is unclear and …

Phylogeography Of Notropis Nubilus (Ozark Minnow), Jason F. Dugan

Dissertations and Theses @ UNI

Periodic glacial cycles beginning 2.6 million years ago to 10,000 years ago forced the repeated contraction, fragmentation, and expansion of the North American biota. In the upper Mississippi River basin three very different areas characterize the topography left by glaciations and still and influence the flora and fauna: Driftless Area, Paleozoic Plateau, and Iowan Surface. The Paleozoic Plateau is located in the northern part of the upper Mississippi River basin, and it is a unique geographical region situated in an area that straddles northeast Iowa, southeastern Minnesota, southwest Wisconsin, and northwest Illinois. This region was bypassed by the last glacial …

Bird Use Of Heterogeneous Native Prairie Biofuel Production Plots, Jarrett D. Pfrimmer

Dissertations and Theses @ UNI

Changing land use practices and agricultural intensification have driven the loss of >90% of native grassland habitats in the Midwestern U.S.A. Consequently, grassland birds have declined more drastically than any other North American guild. Current biofuel production systems in the Midwest rely on high input monoculture crops that provide little habitat value to most grassland birds. The Tallgrass Prairie Center at the University of Northern Iowa is exploring the feasibility of growing and harvesting diverse mixes of native prairie vegetation for use as a sustainable biofuel in a manner that also provides high quality bird habitat. In 2009, 48 research …

Litigation-Fostered Bureaucratic Autonomy: Administrative Law Against Political Control, Daniel E. Walters

Faculty Scholarship

The idea of political control dominates our understanding of both what administrative law does and what it should do. This emphasis on political control, however, downplays the important ways that administrative law facilitates resistance to political control in administrative agencies. In this article, I offer studies of two instances in which agencies harnessed the power of seemingly standard administrative law litigation to resist the imposition of policies by political leadership. I classify these kinds of modes of resistance as instances of “litigation-fostered bureaucratic autonomy” and flesh out the mechanisms that drive the process. Acknowledging the role of such modes of …

A Dialogical Approach To Trade And Environment, Elizabeth Trujillo

Faculty Scholarship

Traditionally, supporters of free trade and environmentalists have regarded each other as the obstacle to development, and both sides have very different views as to what constitutes development. This article considers the various dimensions to international trade governance in the context of the environment and draws from the dialogic theory in comparative constitutional law to frame trade governance regarding the environment in a new way. It uses a dialogical approach to highlight primarily three characteristics of the international trade regime that has fostered enhanced cross-fertilization of trade and environmental issues: (i) the adjudicatory capacity of the World Trade Organization (WTO) …

Courts Rulings Accept Climate Science, Michael Gerrard

Faculty Scholarship

Viewers of certain television networks, readers of certain newspapers, and anyone visiting Capitol Hill would come away with the impression that there are serious questions about whether climate change is occurring and, if it is, whether it is mostly caused by human activity. One place where there are few such questions is the courts. In fact it appears that (with one lone exception in a dissent) not a single U.S. judge has expressed any skepticism, in a written opinion or dissent, about the science underlying the concern over climate change. To the contrary, the courts have uniformly upheld this science, …

Population Genetics Of Thomomydoecus Minor: Ectoparasitic Chewing Lice On Thomomys Bottae Pocket Gophers Of The Rio Grande Valley In New Mexico, Sheree Elizabeth Harper

Dissertations and Theses @ UNI

Thomomydoecus minor is an ectoparasitic chewing louse that lives in intimate association with the pocket gopher Thomomys bottae. Chewing lice are wingless, obligate, host specific parasites that spend their entire life cycle on the fur of their host. Pocket gophers are fossorial and asocial, cut off for most of their lives even from members of their own species. Thus, the life histories of both chewing lice and pocket gophers have been predicted to limit transmission of lice from host to host, thus limiting gene flow among louse infrapopulations found on different hosts and increasing the effect of louse population …

Making Vaccines "On Demand", Anne S. De Groot, Leo Einck, Leonard Moise, Michael Chambers, John Ballantyne, Robert W. Malone, Matthew Ardito, William Martin

Institute for Immunology and Informatics Faculty Publications

The integrated US Public Health Emergency Medical Countermeasures Enterprise (PHEMCE) has made great strides in strategic preparedness and response capabilities. There have been numerous advances in planning, biothreat countermeasure development, licensure, manufacturing, stockpiling and deployment. Increased biodefense surveillance capability has dramatically improved, while new tools and increased awareness have fostered rapid identification of new potential public health pathogens. Unfortunately, structural delays in vaccine design, development, manufacture, clinical testing and licensure processes remain significant obstacles to an effective national biodefense rapid response capability. This is particularly true for the very real threat of “novel pathogens” such as the avian-origin influenzas H7N9 …

Cyclic Peptides Containing Tryptophan And Arginine As Src Kinase Inhibitors, Amir Nasrolahi Shirazi, Rakesh Kumar Tiwari, Alex Brown, Dindyal Mandal, Gongqin Sun, Keykavous Parang

Biomedical and Pharmaceutical Sciences Faculty Publications

A number of cyclic and linear peptides containing various combinations of amino acids were evaluated for their Src kinase inhibitory potency. Among all the peptides, cyclic decapeptide C[RW]₅ containing alternative arginine (R) and tryptophan (W) residues was found to be the most potent Src kinase inhibitor. C[RW]₅ showed higher inhibitory activity (IC₅₀ = 2.8 μM) than C[KW]₅, L(KW)₅, C[RW]₄, and C[RW]₃ with IC₅₀ values of 46.9, 69.1, 21.5, and 25.0 μM, respectively, as determined in a fluorescence intensity-based assay. Thus, the cyclic nature, the presence of arginine, ring size, …

Degradation Of Mangrove Tissues By Arboreal Termites (Nasutitermes Acajutlae) And Their Role In The Mangrove C Cycle (Puerto Rico): Chemical Characterization And Organic Matter Provenance Using Bulk Δ13C, C/N, Alkaline Cuo Oxidation‐Gc/Ms, And Solid‐State 13C Nmr, Christopher H. Vane, Alexander W. Kim, Vicky Moss-Hayes, Collin E. Snape, Miguel Castro Diaz, Nicole S. Khan, Simon E. Engelhart, Benjamin P. Horton

Geosciences Faculty Publications

Arboreal termites are wood decaying organisms that play an important role in the first stages of C cycling in mangrove systems. The chemical composition of Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa leaf, stem, and pneumatophore tissues as well as associated sediments was compared to that of nests of the termite Nasutitermes acajutlae. Nests gave δ¹³C values of −26.1 to −27.2‰ (±0.1) and C/N of 43.3 (±2.0) to 98.6 (±16.2) which were similar to all stem and pneumatophores but distinct from mangrove leaves or sediments. Organic matter processed by termites yielded lignin phenol …

Regulatory T Cell Epitopes (Tregitopes) In Igg Induce Tolerance In Vivo And Lack Immunogenicity Per Se, Yan Su, Robert Rossi, Anne S. De Groot, David W. Scott

Institute for Immunology and Informatics Faculty Publications

Tregitopes are a set of epitopes, derived from IgG, that bind to MHCII, activate nTregs, and promote tolerance. We have now confirmed that coadministration of Tregitopes with a range of proteins (autoantigens and nominal antigens, such as OVA) in vitro and in vivo leads to suppression of T cell and antibody responses to the test antigens. In this study, we demonstrate that Tregitopes are not immunogenic in vivo even when emulsified with strong adjuvants, such as IFA or CFA. Moreover, in vivo administration of Tregitopes with IFA or CFA does not induce Th1 or Th2 cytokine expression under restimulation conditions …

Recalcitrant Arguments, Kiranjeet Kaur Dhillon

Dissertations and Theses @ UNI

On January 26, 2011, Reuters photojournalist Amr Abdallah Dalsh took an image of a unknown veiled woman gesturing at Dalsh and his camera. Using TinEye, a reverse image search engine, I found that 86 circulations and 22 recirculations of the photo were primarily in the United States. US graphic artist Nick Bygon created one of the recirculations, which primarily appeared on US blogs. The photo achieved this level of circulation in the US because it is consistent with, and therefore legible within the symbolic language, of the liberal democratic order. Similar to “Migrant Mother” and “Tank Man”, the photo is …

Self-Defensive Force Against Cyber Attacks: Legal, Strategic And Political Dimensions, Matthew C. Waxman

Faculty Scholarship

When does a cyber attack (or threat of cyber attack) give rise to a right of self-defense – including armed self-defense – and when should it? By "cyber attack" I mean the use of malicious computer code or electronic signals to alter, disrupt, degrade or destroy computer systems or networks or the information or programs on them. It is widely believed that sophisticated cyber attacks could cause massive harm – whether to military capabilities, economic and financial systems, or social functioning – because of modern reliance on system interconnectivity, though it is highly contested how vulnerable the United States and …

Marriage Equality, Gender Equality, And The Women's Convention, Barbara Stark

Hofstra Law Faculty Scholarship

"Marriage equality" remains an elusive goal in this country. About ten years ago I wrote an article suggesting that private ordering would be a good alternative to the rather haphazard and arbitrary state law governing marriage. Instead, I urged couples to draft their own "marriage proposals." As an example, I attached a "Gender Equity Marriage Proposal." The idea was that "gender equity" might be of some interest to some couples, just as others might be more concerned with a child-centered (or wealth- or environment-centered) model.

I meant well. But my premise was deeply flawed for at least two reasons. First, …

Prosecution (Is) Complex, Alafair Burke

Hofstra Law Faculty Scholarship

Post-conviction DNA testing has led to the exoneration of nearly three hundred defendants. As the number of exonerations grows, we are in an era where the once unthinkable is now undeniable. We convict the innocent. We imprison the innocent. We place the innocent on death row. Daniel Medwed brings this reality to life in his captivating book, Prosecution Complex, which carefully documents the myriad ways that prosecutors can contribute to wrongful convictions at every stage of a criminal case. From the charging decision to plea bargaining to trial to post-conviction, Medwed argues, prosecutors face an “ongoing schizophrenia” as they seek …

New Tools For Real-Time Study Of Embryonic Development, Lauren M. Browning

Theses and Dissertations in Biomedical Sciences

Embryonic development represents one of the most complex and dynamic cellular processes in biology, and plays vital roles in understanding of functions of embryonic stem cells (ESCs) and design of ESC-based therapy. Conventional assays and fluorescence-based imaging methods have been widely used for the study of embryonic development. These conventional methods cannot effectively provide spatial and temporal resolutions with sufficient sensitivity and selectivity that are required to depict embryonic development in vivo in real-time at single-cell and single-molecule resolutions. In this dissertation, we have developed a wide range of innovative tools for real-time study of embryonic development. These new tools …

System Governance Analysis Of Complex Systems, Behnido Y. Calida

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to develop and deploy a systems-based framework for analysis of complex governance systems using a multimethodology research design. Two research gaps motivated this research: (1) lack of an integrated conceptualization of a system governance construct, (2) an absence of studies that consider both the governed and governing systems as well as the emergent interactions that arise from within complex governance systems.

The research focused on three primary questions: (1) What are the distinctive characteristics of governance?; (2) What system-based framework can be developed for analysis of governance in complex systems?, and (3) What results …

A Polymer-Based Microfluidic Device With Electrolyte-Enabled Distributed Transducers (Eedt) For Distributed Load Detection, Peng Cheng

Mechanical & Aerospace Engineering Theses & Dissertations

The capability of detecting distributed static and dynamic loads is indispensable in a wide variety of applications, such as examining anatomical structures of biological tissues in tissue health analysis and minimally invasive surgery (MIS) and determining the texture of an object in robotics. This dissertation presents a comprehensive study of a polymer-based microfluidic device with electrolyte-enabled distributed transducers and demonstrates a new concept on using a single microfluidic device for distributed-load detection, which takes advantage of the low-cost microfluidic fabrication technology and the low modulus and biocompatibility of polymer. The core of the device is a single deformable polymer microstructure …

Department of Paediatrics and Child Health

Neisseria meningitidis is one of the leading causes of bacterial meningitis globally and can also cause sepsis, pneumonia, and other manifestations. In countries with high endemic rates, the disease burden places an immense strain on the public health system. The worldwide epidemiology of invasive meningococcal disease (IMD) varies markedly by region and over time. This review summarizes the burden of IMD in different countries and identifies the highest-incidence countries where routine preventive programs against Neisseria meningitidis would be most beneficial in providing protection. Available epidemiological data from the past 20years in World Health Organization and European Centre for Disease Prevention …

Breaking The Mold And Picking Up The Pieces: Rights Of Parenthood And Parentage In Nontraditional Families, J. Herbie Difonzo, Ruth C. Stern

Hofstra Law Faculty Scholarship

The past few decades have shown us myriad ways to form a family. Married couples and their biological offspring no longer define the dominant model, nor do they constitute the majority of domestic arrangements. But while contemporary culture tends to applaud social diversity, we cannot be certain that novel, highly individualized family formation is always consonant with child well-being. Further, courts and legislatures have been slow to acknowledge and accommodate domestic diversity. When judges and lawmakers do confer parental rights on a particular class of individuals, the results are not always equitable or even logical. The era of the traditional …

The Effects Of Thermal Stress And Algal Competition On The Early Life-History Stages Of Porites Astreoides And The Development Of Stress-Detecting Biomarkers For Use In Scleractinan Corals, Kevin C. Olsen

UNF Graduate Theses and Dissertations

Scleractinian coral populations are declining worldwide in response to numerous stressors operating on both global and regional scales. Rising sea surface temperatures associated with global climate change and the increasing frequency of coral-macroalgae competitive interactions are two of the gravest ecological drivers facing coral reef ecosystems. However, little is known about how these stressors interact to impact corals, their health, and potential modes of population recovery. These threats also highlight the need to develop reliable techniques that detect stress in multiple life-history stages of hermatypic corals prior to the degradation of coral reef habitats. To address these concerns we evaluated …

Novel Therapy For Nicotine Addiction In Alcohol Dependent Rats, Bethany Ann Stennett

UNF Graduate Theses and Dissertations

The co-dependence of nicotine and alcohol addiction occurs at high rates, complicates treatment, and is often associated with significant morbidity and mortality. Treatment options of alcohol and tobacco co-dependence are limited. Currently, there are drugs available for nicotine dependence or alcohol dependence. However, there are no therapeutic drugs available on the market for the co-dependence of nicotine and alcohol. Therefore, and important opportunity of new therapeutic options and drug development has presented itself. NT69L, a non-selective neurotensin (NT) agonist, provides a potential novel therapy for nicotine addiction in alcoholics by interacting with the common neurotransmitter circuits supporting the rewarding process …

An In Depth Analyses Of Specific Language Impairment As Compared To Other Developmental Disorders, Adam W. Stein Mr.

UNF Graduate Theses and Dissertations

Specific language impairment (SLI), defined as a disproportionate difficulty in learning language despite having normal hearing, intelligence, and no known neurological or emotional impairment, has been shown to share similar cognitive characteristics with individuals with attention deficit hyperactive disorder (ADHD). However, little research has investigated the dissimilarities in these two different developmental disorders. Children with SLI also show many similar symptoms with individuals diagnosed with dyslexia. The aim of these studies is to get a better understanding of cognitive differences between SLI and ADHD, and the cognitive similarities between SLI and dyslexia. Tests of both verbal and non-verbal measures of …

The Effects Of Multiple Abiotic Stressors On The Susceptibility Of The Seagrass Thalassia Testudinum To Labyrinthula Sp., The Causative Agent Of Wasting Disease, Nichole Danielle Bishop

UNF Graduate Theses and Dissertations

In the past century, seagrasses have experienced massive die off episodes in what has been collectively referred to as “wasting disease.” Researchers generally agree that wasting disease is caused by a protist of the Labyrinthula genus, and that environmental stressors can make some populations of seagrasses more susceptible to infection. The purpose of this study was to examine the combined effects of elevated salinity, elevated temperature, elevated sulfide and night-time hypoxia on Thalassia testudinum health and its response to Labyrinthula sp. infection under controlled conditions. To test these effects, microcosms were utilized and individual seagrass shoots were randomly assigned to …

Nutrient Availability Affects Flowering Rate But Has Limited Influence On Morphology Of The Hooded Pitcher Plant, Sarracenia Minor., Justin M. Lemmons

UNF Graduate Theses and Dissertations

Carnivorous plants perform as both producers and consumers. Botanical carnivory has evolved in sunny, moist, nutrient-poor environments, and the primary nutrient supplied by prey is proposed to be nitrogen. There is a trade-off between carnivorous and photosynthetic structures which corresponds to degree of carnivory expression and available nutrients. This study was conducted on the hooded pitcher plant, Sarracenia minor, which is a facultative wetland plant and Florida-threatened species. Sarracenia minor is considered a specialist myrmecophage and ants characterize the majority of attracted and captured prey. Ants not only provide nutritional benefit, but also protection against herbivory. A natural population …
