Search For Antibiotic-Producing Microorganisms In Sites Affected By Acid Mine Drainage, Hannah A. Bussell

Honors Theses

Antibiotic resistance in bacteria are an escalating problem. Little is known about the potential of microorganisms in sites affected by acid mine drainage (AMD) to be sources of new antibiotics. Sediments from AMD sites in Letcher County, Kentucky, were collected and microorganisms isolated. These samples were screened for their capacity to produce antimicrobial compounds active against known bacteria E. coli and S. aureus. The results showed no antimicrobial activity. This could be due to sample death, incorrect pH of media, or antibiotic resistance already present in the AMD site.

Management Of Recurrent Aphthous Ulcers Exploiting Polymer-Based Muco-Adhesive Sponges: In-Vitro And In-Vivo Evaluation, Dalia Attia, Muhammed Ossama, Caroline Lamie, Mohamed Tarek, Hebatallah Wagdy, Mohamed Elmazar

Pharmacy

Recurrent aphthous ulcer (RAU) is a well-known painful, inflammatory disease with uncertain etiology for which local symptomatic therapy is only available. The aim of this study was to formulate and characterize muco-adhesive sponges containing a mixture of tenoxicam and miconazole nitrate to manage pain, inflammation and avoid candida infection that may accompany RAU due to poor oral hygiene. Two polymers at different concentrations were used to prepare sponges applying simple freeze-drying. Medicated chitosan (2%) sponges (mC2) showed acceptable physical appearance, surface pH (6.3 ± 0.042), porosity (25.7% ± 1.8), swelling index (5.7 ± 0.11), in-vivo and ex-vivo mucoadhesion time (115 …

Balance On Every Ledger: Kwakwaka’Wakw Resource Values And Traditional Ecological Management, Douglas Deur, Kim Recalma-Clutesi, Chief Adam Dick

Anthropology Faculty Publications and Presentations

This chapter illustrates the core environmental values of the Kwakwaka’wakw (Kwakiutl) people on the Pacific coast of Canada to explore how they manifest in the traditional management of coastal natural resources. The authors’ survey of environmental values is based on the authentic knowledge of Chief Adam Dick, a co-author of the chapter. The chapter argues that talking about Indigenous Knowledge without the broader context of environmental values can lead to serious scholarly misunderstandings and insists that long-term collaborations between academic researchers and specialized knowledge holders from Indigenous communities is necessary in order to represent Indigenous Knowledge accurately.

The Impact Of Serum Zinc Levels On Children With Acute Gastroenteritis, Furat Abdul-Azeez, Saja Abdulwahhab, Mohammad Ibraheem

Iraqi Postgraduate Medical Journal

ABSTRACT: BACKGROUND: Diarrhea is the leading cause of morbidity and mortality in children in developing countries. Acute-onset diarrhea is usually a self-limited disease; however, acute infection can have                            a protracted course.     Zinc is an essential nutritional element, with a broad spectrum of biological activities in humans; this element plays an important and vital role in the physical development of digestive and immune systems.  Zinc deficiency is common in children from developing countries due to lack of intake of animal foods, high dietary phytate content, inadequate food intake, and increased fecal losses during diarrhea. OBJECTIVE: To assess serum zinc level in …

Microplastics In Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, And Aquarium Exhibit Outcomes, Britta Rahel Baechler

Dissertations and Theses

Up to 23 million metric tons of mismanaged plastics enter the global ocean annually. Microplastics (MPs;<5mm) degrading. MPs leak into the environment and now pervade every corner of the earth, with implications for animal, plant, ecosystem and human health. It is important to understand localized environmental MP prevalence, distribution and organismal uptake in order to determine the extent of MP pollution, and ultimately unlock solution sets to reduce transmission of MPs into the natural world. In Chapter 2, I quantified MP types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 coastal sites in Oregon. Both of these species are integral to culture, economy, gastronomy and food security along the United States West Coast. In Chapter 3, I quantified MPs in Pacific razor clams collected from 8 Olympic Coast, Washington sites, administered questionnaires to recreational razor clammers and subsequently estimated annual MP exposure of those Olympic Coast razor clam harvester-consumers surveyed. In Chapter 4, I designed and installed an educational ocean plastic …

Viral Load, T-Cells Count, And T-Cells Sars-Cov-2 Cross-Reactivity Constitute A Triad Governing The Varied Prognosis Of Covid-19, Ahmed Abdulamir, Rand Hafidh

Iraqi Postgraduate Medical Journal

The novel coronavirus disease, COVID-19, impose a challenge on scientists and physicians in terms of understanding the phases of viral pathogenesis and host immunopathogenesis that lead to the fatal complications of the disease. Three pillars have been thought to play essential role in determining the prognosis of COVID-19, namely the viral load of SARS-CoV-2, the count and functionality of T lymphocytes and the crossreactivity of T lymphocytes with common cold coronaviruses. Collectively, these three factors might constitute a triad governs the time-based and phase-based progression of COVID-19 patients. This review discusses the role of this triad in COVID-19 and presents …

Kesmas

In 2007, the Philippine government passed the Anti-Rabies Act to address rabies in the country. However, rabies is still a major public health concern in many provinces. This study aimed to evaluate the knowledge, attitude, and practices (KAP) of residents on rabies, the Anti Rabies Act, and responsible pet ownership (RPO) in Pampanga, Philippines. A cross-sectional survey was done from October 2017 to February 2018 in 92 randomly selected barangays in the province. Questionnaires were adapted from similar studies. Logistic regression was used to identify factors associated with KAP. Results showed that most people have good knowledge of the Anti-Rabies …

Whole Genome Sequencing Identified A 16 Kilobase Deletion On Eca13 Associated With Distichiasis In Friesian Horses, E. A. Hisey, H. Hermans, Z. T. Lounsberry, F. Avila, R. A. Grahn, K. E. Knickelbein, S. A. Duward-Akhurst, M. E. Mccue, Theodore S. Kalbfleisch, M. E. Lassaline, W. Back, R. R. Bellone

Veterinary Science Faculty Publications

BACKGROUND: Distichiasis, an ocular disorder in which aberrant cilia (eyelashes) grow from the opening of the Meibomian glands of the eyelid, has been reported in Friesian horses. These misplaced cilia can cause discomfort, chronic keratitis, and corneal ulceration, potentially impacting vision due to corneal fibrosis, or, if secondary infection occurs, may lead to loss of the eye. Friesian horses represent the vast majority of reported cases of equine distichiasis, and as the breed is known to be affected with inherited monogenic disorders, this condition was hypothesized to be a simply inherited Mendelian trait.

RESULTS: A genome wide association study (GWAS) …

Soil Water Dynamics Within Variable Rate Irrigation Zones Of Winter Wheat, Elisa Anne Woolley

Theses and Dissertations

Understanding the spatial and temporal dynamics of soil water and crop water stress within a field is critical for effective Variable Rate Irrigation (VRI) management. Proper VRI can result in improved protection of the crop from early onset of crop water stress while minimizing runoff and drainage losses. The objectives of this study are (1) to examine zone delineation for informing irrigation recommendations from volumetric water content (VWC) and field capacity (FC) to grow similar or greater wheat yields with less water, (2) evaluate the ability to model soil and crop water dynamics within a season and within a field …

Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki

CODEE Journal

A neural cell or neuron is the basic building block of the brain and transmits information to other neurons. This paper demonstrates the complicated dynamics of the neuron through a numerical study of the Hodgkin-Huxley differential equations that model the ionic mechanisms of the neuron: slight changes in parameter values and inputted electrical impulses can lead to very different (unexpected) results. The methods and ideas developed for the ordinary differential equations are extended to partial differential equations for Hodgkin-Huxley networks of neurons in one, two and three dimensions.

Improving Rangeland Seedling Recruitment Using Fungicide Seed Coatings And Golden Eagle Reproductive Success In Relation To Explosive Military Tests And Trainings, Benjamin William Hoose

Theses and Dissertations

The objective of the first chapter of this thesis was to determine whether fungicide seed coatings constitute an effective strategy for increasing seedling recruitment in restoration scenarios in the Intermountain West. We tested a mixture of four fungicides that address potential fungal pathogens to bluebunch wheatgrass, a dominant bunchgrass that is commonly used in restoration. Across two sites and three years, we found that the fungicide seed coating increased emergence in five of the six sites and years, with an average increase of 59.1% over the control. There was a strong interaction (P < 0.001) between the effects of fungicide treatment, the year and the site on emergence. This interaction was likely related to the effects of the hydrothermal microsite environment on disease severity. Further research is necessary to fully understand the conditions under which fungicide seed coatings are most likely to be effective. The objectives the second chapter of this thesis were to 1) estimate the effects of golden eagle nest proximity to explosive disturbances on reproductive success given other relevant habitat variables (e.g. indices of topography and vegetation), and 2) determine the relative importance of nest proximity to explosive disturbances as a predictor of golden eagle reproductive success compared to other relevant habitat variables. Reproductive success data were collected from nesting territories within and surrounding land controlled and managed by the US Department of Defense. We fit the reproductive survey data using generalized linear mixed-effects models comprised of unique, hypothesis-based sets of habitat variables. We compared the models using AICc-based model selection processes. Given the best approximating model, we found no evidence that the likelihood of reproductive success was affected by nest proximity to explosive disturbances (P = 0.460). We further found nest proximity to explosive disturbances consistently ranked in the bottom 50% of relative variable importance. These results may indicate golden eagle tolerance or habituation to explosive military tests and trainings. Although the two chapters of this thesis are disjointed, they are loosely unified by the ecological importance of disturbance, invasive species, and restoration within the Great Basin ecoregion.

Characteristics Biolubricant Enriched With Nanoparticle Additives: A Review, Zhahra Hanif Sholiha, Gaguk Jatisukamto

Journal of Mechanical Engineering Science and Technology (JMEST)

The engine movement mechanism is a system composed of machine elements that contact or rub against each other between these surfaces. Surfaces that rub against each other will cause a friction force that causes wear on the surface, so it requires energy to fight the friction force. Lubricants are needed to reduce friction and reduce wear rates, where lubricants are generally made of mineral materials. Lubricants made from synthetic materials are non-renewable and cause environmental problems. The development of biolubricants as lubricating materials based on animal fats or vegetable oils is continuously being carried out. This study aims to observe …

Criminology As Epistemic Necropolitics, Tamari Kitossa Phd

Social Transformations Journal of the Global South

I argue in this essay that from 1492 to the present, the Global North has used theories of “crime,” its causation and control, as part of a three-pronged epistemic necropolitical attack on the Global South. I suggest that the emergence of critical criminology and its more recent offshoots, given their dependence on the present or hypothetical war making and coercive state, are themselves a part of the problem. I suggest criminology is a Trojan Horse that brings epistemic toxic waste and destruction in the guise of deterministic theories on crime and its control. Like their Inquisitorial predecessors, I suggest criminology …

Moisture Reduction Of Honey In Dehumidification And Evaporation Processes, Anang Lastriyanto, Sasongko Aji Wibowo, Erwan Erwan, Firman Jaya, Jati Batoro, Dewi Masyithoh, J.S.A Lamerkabel

Journal of Mechanical Engineering Science and Technology (JMEST)

The high water content of honey can lead to fermentation and accelerate the deterioration of honey. One way to prevent fermentation in honey is to reduce the water content of honey. There are several ways to reduce the water content of honey, namely through a dehumidifier and evaporation. This study aimed to examine the relationship of reduced water content towards time in between dehumidifier and evaporation processes. The research method uses an exponential equation model to determine the value of the constant (K). The constant value (K) is used to predict the rate of reduction in moisture content between the …

The stratigraphy and structure beneath Dyer County, Tennessee, were mapped using lignite exploration wells, water wells, US Army Corps of Engineers borings, and previously interpreted seismic reflection lines to better understand the seismic threat of the underlying New Madrid seismic zone structures. New Madrid seismic zone earthquakes are concentrated on faults of the Reelfoot rift, one system of which is the northwest-trending Lake County uplift and Tiptonville dome, which extends in northwestern Tennessee through Lake and Obion counties into Dyer County. Structure contour maps of the tops of the Paleozoic, Cretaceous, and Eocene sections were made to produce cross-sections and …

Swarm-Based Design Of Proportional Integral And Derivative Controllers Using A Compromise Cost Function: An Arduino Temperature Laboratory Case Study, Paulo De Moura Oliveira, John Hedengren, Eduardo Solteiro Pires

Faculty Publications

Simple and easy to use methods are of great practical demand in the design of Proportional, Integral, and Derivative (PID) controllers. Controller design criteria are to achieve a good set-point tracking and disturbance rejection with minimal actuator variation. Achieving satisfactory trade-offs between these performance criteria is not easily accomplished with classical tuning methods. A particle swarm optimization technique is proposed to design PID controllers. The design method minimizes a compromise cost function based on both the integral absolute error and control signal total variation criteria. The proposed technique is tested on an Arduino-based Temperature Control Laboratory (TCLab) and compared with …

Library Philosophy and Practice (e-journal)

Coronaviruses in the electron micrographs are medium-sized RNA viruses with a very distinctive profile. Coronaviruses infect many species of animals, including humans. Coronaviruses have been described for more than 50 years. Human coronaviruses started its existence in 1965, when Tyrrell and Bynoe (1966) found that a virus called B814 could transfer. It was found in human embryonic tracheal organ cultures from an adult with a common cold respiratory tract. Inoculation of human volunteers of the medium of these cultures showed the presence of an infectious agent. Two new human coronaviruses associated with respiratory diseases have been reported since identification of …

The Outer Space As A New Theater Of Operations. Some Ethical-Legal Considerations En Security And The Global Commons, Edited By J. Martin Ramirez, And Bartolomé Bauzá-Abril, Juan Cayón Peña, Saloomeh Yousefian

Capítulos de libros

The advance of non-state actors in outer space and the unilateral declarations and events of the leading space powers reveal an undeniable change in outer space's political and strategic status quo. This phenomenon should lead to changes in the standard configuration that the International Community has been giving until now to outer space as a global common. This contribution analyzes the mentioned legal regime and main recent milestones that lead to thinking about its manifest disuse to point out a series of ethical considerations. These considerations are fundamentally based on classical authors who are recognized fully valid, from …
