Correlation Between Ocean Acidification And Zooplankton In The South Pacific Gyre, Samuel Noonan, Rachel Scudder
Correlation Between Ocean Acidification And Zooplankton In The South Pacific Gyre, Samuel Noonan, Rachel Scudder
DU Undergraduate Research Journal Archive
The South Pacific Gyre is a naturally occurring carbon sink, meaning that it absorbs atmospheric carbon dioxide by dissolving it into the moving surface water.The dissolution of CO2 level will dictate the water’s acidic levels a larger the concentration of dissolved CO2 is known to increase the salt water’s acidity. A great amount of the ocean’s biomass is composed of calcifying organisms,which produce tests or shells made from calcium carbonate CaCO3.The goal of our project is to determine if there is a correlation between the water acidity across various locations, as we sailed through the South Pacific gyre and the …

The Investigation Of Lactoferrin Nitration: Quantification, Function, And Inhibition, Amani Yahya Alhalwani
Electronic Theses and Dissertations
Lactoferrin (LF) is an iron-binding glycoprotein of molecular mass ca. 80 kDa that is predominantly found in mammalian body fluids. Lactoferrin is a multifunctional protein that has a wide range of properties such as antibacterial, antiviral, anti-inflammatory, and anti-allergic functions. Tyrosine residues in the protein play a part in many lactoferrin functions. Protein tyrosine nitration modification represents an oxidative and nitrosative stress process which can be caused by the exposure of proteins to oxidants from air pollution or disease. Understanding the way nitrated lactoferrin interacts with the biochemical environment of the body is thus important to the broader goal of …

Chemistry and Biochemistry: Faculty Scholarship
Fungal spores as a prominent type of primary biological aerosol particles (PBAP) have been incorporated into the COSMO-ART (Consortium for Small-scale Modelling- Aerosols and Reactive Trace gases) regional atmospheric model. Two literature-based emission rates for fungal spores derived from fungal spore colony counts and chemical tracer measurements were used as a parameterization baseline for this study. A third, new emission parameterization for fluorescent biological aerosol particles (FBAP) was adapted to field measurements from four locations across Europe. FBAP concentrations can be regarded as a lower estimate of total PBAP concentrations. Size distributions of FBAP often show a distinct mode at …
