THE EFFECT OF ANTHROPOGENIC ACTIVITY ON SEA TURTLE NESTING AND HABITAT USAGE IN FLORIDA, USA
(2018-05)Sea turtles have complex life histories that make them difficult to study. Using easily-accessible data, such as nesting and stranding occurrences, can help to efficiently elucidate driving factors in the population ... -
Effect of Bioglass Incorporation into Electrochemically Aligned Collagen Threads on Mechanical Properties and Cell-Mediated Mineralization
(2017-10)Bone related diseases and disorders are a significant socioeconomic burden in the United States. Autografts and allografts are most commonly used for the treatment of bone defects and non-unions; however, they are associated ... -
Effect of Cavitation Regimes on Stepped Diesel Injectors
(2018-05)The objective of this work was to determine the effects of different cavitating flow regimes on a stepped orifice geometry relevant to diesel injectors. Conventional diesel orifice geometries consist of a single tapered ... -
Effect of Electron Demand on Sensing Behavior of Carbazolopyridinophanes
(2020-08)Hydrazine (HZ), monomethylhydrazine (MMH), and 1,1-dimethylhydrazine (UDMH) are widely used as high energy rocket propellants in bipropellant rocket engines. However, hydrazine and its derivatives are highly flammable and ... -
The Effect of Environmental Muck Dredging on Abundance and Community Richness of Benthic Amphipods in the Indian River Lagoon
(2019-05)Anthropogenic eutrophication has polluted and degraded estuarine ecosystems throughout the world. The Indian River Lagoon (IRL), a diverse North American estuary, has accumulated an abundance of Fine-Grained Organic-Rich ... -
Effect of Film Cooling Hole Size on a Turbine Rotor Blade
(2018-12)The objective of this study was to evaluate the effect of the cooling hole size on the adiabatic film cooling effectiveness over a rotating turbine blade section. The study was conducted using ANSYS FLUENT to determine ... -
Effect of Industry Clusters and Commodity Flow Characteristics on the Selection of Freight Transportation Modes in the United States with Advanced Econometric Approaches
(2019-05)Mode choice is an important strategic decision for shippers to carry commodities efficiently. Freight mode-choice is an important activity to develop a successful freight transportation business in the private sector and ... -
The Effect of Simulated Mangrove Forest Width on Shoreline Stabilization at Multiple Tidal Water Levels
(2021-05)Red mangrove (Rhizophora mangle) forests protect hundreds of miles of Florida’s shorelines from erosion and wave damage associated with severe storms and daily wave action. Shorelines are often protected from erosion with ... -
Effect of Tannic Acid Crosslinking on the Mechanical Properties of Collagen Scaffolds and Melanoma Cell Proliferation
(2017-07)Metastatic melanoma is responsible for nearly 10,000 deaths in the United States each year. While the prognosis for patients with localized early stage melanoma cancer is good, the chances of survival for patients with ... -
Effect of the Wake Structure on Drag Coefficient for a Thin Flexible Wire
(2017-04)The present research work focuses on investigating the effect of wake structure on the drag coefficient of a thin flexible wire. Previous researchers have investigated the flow characteristics around the cylinder and ... -
Effect of Thermal Treatments on Mechanical Properties and Bioactivity of Third Generation of Bioactive Glass. A step for commercialization success of third Generation Bioactive Glasses
(2014-12)Unavailability of donors for transplanting bone to help people with orthopedic imparities gave rise to the metal implants that could be made in factories. This seemed like a good solution as it was available to all the ... -
