Acid-Triggered Self-Assembled Egg White Protein-Coated Gold Nanoclusters For Selective Fluorescent Detection Of Fe3+, No2-, And Cysteine, Wenyan Li, Xiangping Wen, Hemiao Zhao, Wenjun Yan, John F. Trant, Yingqi Li

Chemistry and Biochemistry Publications

Herein, we present a simple and economical synthesis for the first multianalyte probe able to selectively quantify the concentrations of Fe3+, NO2-, and cysteine. It comprises H+-triggered self-assembled gold nanoclusters (AuNCs@EW/H+, AuEHs), showing enhanced red fluorescence at 640 nm. The AuEH is a good fluorescent nanosensor for Fe3+ and NO2- with detection limits of 1.40 and 2.82 nM, respectively. Iron detection, through fluorescence quenching, occurs because of nanocluster aggregation elicited by the complexation of Fe3+ with amino acids on the surface of AuEH; nitrite detection likely proceeds through fluorescence quenching via the disassembly of the nanoclusters following irreversible oxidation by …

The Maumee River is the primary source for nutrients fueling seasonal Microcystis-dominated blooms in western Lake Erie's open waters though such blooms in the river are infrequent. The river also serves as source water for multiple public water systems and a large food services facility in northwest Ohio. On 20 September 2017, an unprecedented bloom was reported in the Maumee River estuary within the Toledo metropolitan area, which triggered a recreational water advisory. Here we (1) explore physical drivers likely contributing to the bloom's occurrence, and (2) describe the toxin concentration and bacterioplankton taxonomic composition. A historical analysis using 10-years …

The State Giveth And Taketh Away: Public Sector Labour Law, The Legitimacy Of The Legislative Override Power And Constitutional Freedom Of Association In Canada, Claire Mumme

Law Publications

This article investigates the role of courts and legislatures in the design and enforcement of labour laws in the context of public sector employment. It does so by focusing on government employers’ legislative ability to temporarily override public sector labour rights, or to displace outcomes achieved under their processes. This issue is analysed through a case study of Canada, a country which offers constitutional protections for freedom of association, but which is also constructing a highly deferential approach to the constitutional review of override statutes. As a result of this deference, governments have been afforded significant leeway in the use …

A First Look At The Metabolic Rate Of Greenland Sharks (Somniosus Microcephalus) In The Canadian Arctic, Eric Ste-Marie, Yuuki Y. Watanabe, Jayson M. Semmens, Marianne Marcoux, Nigel E. Hussey

Integrative Biology Publications

Metabolic rate is intricately linked to the ecology of organisms and can provide a framework to study the behaviour, life history, population dynamics, and trophic impact of a species. Acquiring measures of metabolic rate, however, has proven difficult for large water-breathing animals such as sharks, greatly limiting our understanding of the energetic lives of these highly threatened and ecologically important fish. Here, we provide the first estimates of resting and active routine metabolic rate for the longest lived vertebrate, the Greenland shark (Somniosus microcephalus). Estimates were acquired through field respirometry conducted on relatively large-bodied sharks (33–126 kg), including the largest …

Calling Songs Of Neotropical Katydids (Orthoptera: Tettigoniidae) From Panama, Hannah M. Ter Hofstede, Laurel B. Symes, Sharon J. Martinson, Tony Robillard, Paul Faure, Shyam Madhusudhana, Rachel A. Page

Integrative Biology Publications

Understanding the ecology and evolution of animal communication systems requires detailed data on signal structure and variation across species. Here, we describe the male acoustic signals of 50 species of Neotropical katydids (Orthoptera: Tettigoniidae) from Panama, with the goal of providing data and recordings for future research on katydid communication, evolution, ecology, and conservation. Male katydids were recorded individually using an ultrasound-sensitive microphone and high-sampling rate data acquisition board to capture both audible and ultrasonic components of calls. Calls varied enormously in duration, temporal patterning, peak frequency, and bandwidth both across and within subfamilies. We confirm previous studies showing that …

Comparison Of Mercury Dynamics In High Arctic Lakes, Karista Elizabeth Hudelson

Electronic Theses and Dissertations

Arctic lakes and their watersheds are being simultaneously subjected to the deposition of atmospheric pollutants such as mercury (Hg), and warming. Once Hg enters an ecosystem, it may become methylated, greatly increasing its toxicity and reducing organisms’ ability to eliminate it. Mercury is bioaccumulative and thus found at high concentrations in land-locked Arctic char (Salvelinus alpinus) and other top predators. In sediment, Hg methylation rate is temperature-dependent, and [Hg] in Arctic predatory fish has been correlated with trends in air temperature. Despite reductions in Hg emissions in North America and Europe, [Hg] continues to rise in some Arctic species. The …

An In Silico Approach To Enzymatic Synthesis Of Fucooligosaccharides Using Α-L-Fucosidase From Thermotoga Maritima, Emmanuel Pérez-Escalante, Luis Guillermo González-Olivares, Araceli Castañeda-Ovando, Alma Elizabeth Cruz-Guerrero, John F. Trant, Wendolyne López-Orozco, Luis Humberto Mendoza-Huizar, Sergio Alatorre-Santamaría

Chemistry and Biochemistry Publications

Abstract: Fucooligosaccharides comprise the primary group of human milk oligosaccharides. Due to their beneficial properties, a series of synthetic methods have been proposed to obtain them. Enzy- matic methods show great promise, and α-L-fucosidase from Thermotoga maritima has emerged as a powerful catalyst for their production. Nonetheless, the enzyme’s limited substrate scope has de- layed its wider application. The present work aims to compare the relative reactivity of fucose, pNP-fucose, and ethyl-fucose, while also exploring the molecular interactions of these fucosyl-donors with the enzyme through a combination DFT and docking analysis. The HOMO-LUMO band gaps range from −7.14571 to −4.24429 …

Design Of A Real-Time Method For Detection And Evaluation Of Corrosion In Vehicles, Kunj Dhonde

Electronic Theses and Dissertations

Automobiles endure several challenges when operating on the road that can degrade their performance, functionality, appearance, and overall utility. Although, corrosion is very ancient, it is the most dangerous hazard to an automobile. Corrosion can be defined as natural interaction between the metal and its surrounding atmosphere which results in oxidation of metal. This leads to change in metal properties and can be severely dangerous. One of the easiest ways to recognize corrosion is by using visual inspection methods. Visual inspection results are highly dependent on the operator’s way of analyzing corrosion and operator’s experience. Thus, visual inspection method lack …

Molecular Techniques To Advance The Conservation Of Imperilled Freshwater Fishes, Ryland George Corchis-Scott

Electronic Theses and Dissertations

The conservation of imperilled fishes should be informed by species-specific genetic information. However, there are a lack of molecular data for most species at risk with the development of species-specific primer acting as a barrier to genetic evaluations. Here, I describe the development and preliminary testing of a set of microsatellite markers for the imperilled Lake Chubsucker (Erimyzon sucetta). These markers are apparently diploid, are polymorphic, and have been demonstrated to amplify individuals from across the species’ North American range. The microsatellite markers described in this thesis have applications for population genetics as well as informing source population selection for …

Community Composition Of Aquatic Invertebrates Along Dissolved Oxygen Gradients In Lake Huron Coastal Wetland Wet Meadows, Danielle Elizabeth Gunsch

Electronic Theses and Dissertations

Wetlands are an ecotone between terrestrial and aquatic environments and therefore support a diverse and unique flora and fauna. Macroinvertebrates make up a substantial portion of the biodiversity. The relationship between aquatic invertebrate community composition and the association with submergent and emergent macrophyte biomass is relatively well documented. However, the constraints imposed by conditions in wet meadow zones – areas that are intermittently flooded but whose soils are typically water-saturated and anoxic are less well understood. I investigated the relative importance of dissolved oxygen along the water depth gradient and its influenced on invertebrate community composition in comparison to the …

Perception And Performance Of Working Memory: Insights Into Test Anxiety, Rebecca Grossman

Electronic Theses and Dissertations

Test anxiety is a common phenomenon that can be detrimental to cognitive performance, academic achievement, and mental health. One mechanism consistently identified as playing a role in such deficits is working memory. While many studies have investigated the relationship between working memory and test anxiety, approaches to measuring working memory have varied between using assorted standardized behavioural measures and self-report inventories. While self-report inventories are often found to be valid, there is some evidence suggesting that subjective appraisal of functioning might not be accurate in all contexts. Therefore, the purpose of this study was to determine whether self-appraisal of working …

Diagnosing the correct types of the disease is essential to the effective treatment. The diagnosis may not always be straightforward from the biological tests especially during the early stages of the disease. Human body responds to the disease by producing certain proteins. If we know which genes are active, that is, which proteins are being produced, we can more accurately classify disease subtypes. This study is based on the genetic information extracted from the patient’s biological sample and is used to classify cancer subtypes. Among different types of genetic data, we consider RNA-seq data in this thesis. Studies based on …

A Methodological Framework For The Assessment Of Level Of Service Of Stormwater Infrastructure, Dorcas Appiah

Electronic Theses and Dissertations

With climate change becoming the single most concern in the contemporary world, stormwater management has been receiving greater attention than before. Even though stormwater infrastructure plays a pivotal part in the municipality, there are no available standards or tools to assess its level of service (LOS). Stormwater infrastructure should manage the quantity and quality of stormwater by controlling flooding, pollutants and ensuring public safety. Currently, creating a proactive stormwater infrastructure management system is hindered by a lack of resources despite the importance of these resources for proper stormwater infrastructure management. In an advanced asset management system, LOS assessment is identified …

Control Of Four-Wire Inverter-Interfaced Dgs For Accurate Fault Type Classification, Wael Radwan

Electronic Theses and Dissertations

Inverter-interfaced distributed generators (IIDGs) generate fault currents that are different from those generated by conventional synchronous generators (SGs). As a result, commercial relays—that utilize current-angle-based phase selection measurements—misidentify faulty phase(s), which adversely impact the grid resiliency and reliability. In this thesis, a new control scheme is proposed to regulate the sequence components of the IIDG currents during unbalanced faults to ensure accurate fault type classification by commercial relays. The proposed controller controls the positive-sequence and negative-sequence currents in the dq-frame with a decoupled synchronous reference frame (DDSRF) based phase-locked loop (PLL) for components extraction and synchronization. It also uses a …

Progress Towards The Synthesis Of Carbohydrate-Based Biomedical And Material-Science Relevant Molecules, Seyed Iraj Sadraei

Electronic Theses and Dissertations

Cancer cells express unique carbohydrate signatures on their surfaces known as tumour-associated carbohydrate antigens (TACAs). These antigens are not typically found on healthy cells and therefore are promising targets for immunotherapy using adap-tive immune response tools. If the immune system could theoretically be “trained” to tar-get this molecule, then the immune system could be used to help eradicate any cancer cells from the host. A problem with carbohydrate-based targets is they are not stable in the body because of their inherent acetal functionality: the glycosidic bond. This research aims to remove the unstable acetal functionality in carbohydrates by replacing the …

Dissolved Microcystin Release Coincident With Lysis Of A Bloom Dominated By Microcystis Spp. In Western Lake Erie Attributed To A Novel Cyanophage, Katelyn M. Mckindles, Makayla A. Manes, Jonathan R. Demarco, Andrew Mcclure, R. Michael Mckay, Timothy W. Davis, George S. Bullerjahn

Great Lakes Institute for Environmental Research Publications

Western Lake Erie (Laurentian Great Lakes) is prone to annual cyano- bacterial harmful algal blooms (cHABs) dominated by Microcystis spp. that often yield microcystin toxin concentrations exceeding the federal EPA recreational con-tact advisory of 8 μg liter-1. In August 2014, microcystin levels were detected in fin-ished drinking water above the World Health Organization 1.0 μg liter-1 threshold for consumption, leading to a 2-day disruption in the supply of drinking water for >400,000 residents of Toledo, Ohio (USA). Subsequent metatranscriptomic analysis of the 2014 bloom event provided evidence that release of toxin into the water sup-ply was likely caused by cyanophage …

Mimicking Transgenerational Signals Of Future Stress: Thermal Tolerance Of Juvenile Chinook Salmon Is More Sensitive To Elevated Rearing Temperature Than Exogenously Increased Egg Cortisol, Theresa R. Warriner, Christina A.D. Semeniuk, Trevor E. Pitcher, Daniel D. Heath, Oliver P. Love

Great Lakes Institute for Environmental Research Publications

Elevated temperatures resulting from climate change are expected to disproportionately affect ectotherms given their biological function has a direct link to environmental temperature. Thus, as climate change leads to rapid increases in water temperatures in rivers, aquatic ectotherms, such as fish may be highly impacted. Organisms can respond to these stressors through flexible and rapid phenotypic change induced via developmental and/or transgenerational plasticity. In oviparous species, gravid females may translate environmental stress across generations via increased exposure of eggs to maternally derived glucocorticoids (i.e., maternal stress), which has been shown to result in diverse phenotypic effects in offspring. Recent studies …

Correspondence Of Beach User Perception, Lifesaving Strategies And Rip Currents At Brackley Beach And Cavendish Beach Prince Edward Island, Summer Locknick

Electronic Theses and Dissertations

Rip currents are an emerging public health hazard, with the potential to have serious socioeconomic impacts on coastal communities globally. Rip currents, colloquially known as rips, are common along the north shore of Prince Edward Island, and are associated with a transverse bar and rip morphology that tends to develop as the bars migrate landward following winter storms. The rip morphology tends to develop at the height of the economically important tourist season. Several drownings have occurred within and adjacent to Prince Edward Island National Park (PEINP) in recent years, and they have been attributed to rip currents at or …

Adaptive Indoor Pedestrian Tracking Using Foot-Mounted Miniature Inertial Sensor, Ravindra Kumar Dhanapal

Navigating Online And Offline Social Spaces: Interpersonal Relationships And Problematic Gaming Behaviour In Mmorpg Players, Aranda Christine Wingsiong

Electronic Theses and Dissertations

Previous research suggests that individuals who play Massively Multiplayer Online Roleplaying Games (MMORPGs) may experience interpersonal benefits from their in-game interactions with other players (Kaczmarek & Drazkowski, 2014). At times, however, these online relationships may develop at the expense of their offline relationships and some players may even be at risk for developing problematic gaming behaviours (PGB). The current study aimed to better understand the online and offline interpersonal experiences of MMORPG players and to identify interpersonal risk factors for developing PGB. A total of 149 MMORPG players between the ages of 18 to 46 years completed a set of …
