We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth System Climate Model designed for millennial timescale simulations. The model includes prognostic tracers for the stable nitrogen isotopes, ¹⁴N and ¹⁵N, in the nitrate (NO₃ˉ), phytoplankton, zooplankton, and detritus variables of the marine...
Nitrogen (N) fixation by specialized microorganisms (diazotrophs) influences global plankton productivity because it provides the ocean with most of its bio-available N. However, its global rate and large-scale spatial distribution is still regarded with considerable uncertainty. Here we use a global ocean nitrogen isotope model, in comparison with δ15NO3 observations,...
More and more people have incorporated GIF in their messaging these days and often send gif as a reply. GIF is Graphics Interchange Format and is a short-animated picture without a sound. Searching a trivial gif with a regular emotion is easy to find but if some iconic expression is...
Kombucha is a traditional fermented beverage that has become increasingly popular in the United States due to its perceived health benefits and unique flavor profiles. The drivers of kombucha flavor have not been fully characterized, at least in part because it is produced using a complex microbial community, leading to...
Harriet Beecher Stowe’s Uncle Tom’s Cabin is known for altering the social and political landscape of the United States during a particularly tumultuous, divided period. The novel, which tells the story of enslaved man Uncle Tom, had wide influence and was considered to help “lay the groundwork for the Civil...
The topics in this dissertation are centered around the way that trees respond to environmental stress in the climates where they occur. Though forests across the planet are expected to experience change in local climate due to historic and ongoing anthropogenic greenhouse gas emissions, the effects of climate change will...
We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth system climate model designed for millennial timescale simulations. The model includes prognostic tracers for the two stable nitrogen isotopes, 14N and 15N, in the nitrate (NO3−), phytoplankton, zooplankton, and detritus variables of the...
These stories are an attempt to give a distinct literary voice to the people and places of rural Southern Indiana. They also strive to deal with certain elements indigenous to that region, some of which can be described generally as the tension between modernization and tradition, family and marriage as...
Polyfunctional thiols are sulfur containing compounds that are important to the flavor and aroma profile of some foods and beverages. S. Cerevisiae has been shown in wine yeast that it is capable of producing these thiols to create a fruity aroma and flavor profile. IRC7, a gene that codes the...
Spreadsheets are a widely used end-user programming tool. Field audits have found that 80-90% of spreadsheets created by end users contain textual and formula errors in spreadsheets. Such errors may have severe negative consequences for users in terms of productivity, credibility, or profits. To solve the problem of spreadsheet errors,...
