Underwater Frp Repair Of Corrosion Damaged Prestressed Piles, Kwangsuk Suh
Underwater Frp Repair Of Corrosion Damaged Prestressed Piles, Kwangsuk Suh
USF Tampa Graduate Theses and Dissertations
The goal of the dissertation was to quantify the role of FRP in repairing corroded prestressed piles in a marine environment and to demonstrate the feasibility of using it for field repairs. Three laboratory studies and two field demonstration projects were undertaken to meet this goal.In the first study, corroded specimens were repaired under water and tests conducted to determine the extent of strength retained immediately after wrapping and after further accelerated corrosion. Results showed that the underwater wrap was effective in restoring and maintaining lost capacity in both situations.The second study attempted to determine the effectiveness of FRP for …
Investigation Of Cretaceous Molluscan Shell Material For Isotopic Integrity: Examples And Implications From The Baculites Compressus/Cuneatus Biozones (Campanian) Of The Western Interior Seaway, Ashley Da Silva
USF Tampa Graduate Theses and Dissertations
Whether a global greenhouse interval is a distinct or distant future, it is important to understand the dynamics of a greenhouse system. During such intervals the oceans, in the absence of sizeable polar ice caps, flood the continental shelf. The stratification and circulation of these epicontinental seas are open to debate, because there are no Recent analogs. The carbon and oxygen stable isotope record of fossil molluscan shell from epicontinental seas has the potential to reveal their stratification and seasonal cycles. As a study sample, mollusks from the Baculites compressus and Baculites cuneatus biozones of the Western Interior Seaway of …
Modeling The Advantages And Disadvantages Of The Coral-Algal Symbiosis, Dana Joy Gaydos
Modeling The Advantages And Disadvantages Of The Coral-Algal Symbiosis, Dana Joy Gaydos
USF Tampa Graduate Theses and Dissertations
Coral reefs thrive in nutrient-deficient environments yet function among the most productive ecosystems on Earth as a consequence of the symbiosis between coral hosts and their symbiotic zooxanthellae. The symbiotic unit (holobiont) can utilize both inorganic and organic sources of nutrients for the accumulation of carbon and nitrogen required for metabolism, growth, and reproduction. An iterative model was created to describe the flux of carbon and nitrogen between a host and its algae. The model design is based on a previously published conceptual model of algal symbioses; functions and values of input parameters are based on published studies of the …
