Exploring The Effects Of Varied Land Use On Elemental Concentrations Within Streams, Logan Jennings
Exploring The Effects Of Varied Land Use On Elemental Concentrations Within Streams, Logan Jennings
Biological and Agricultural Engineering Undergraduate Honors Theses
It is well documented that human activity influences the chemistry of surrounding waters. As such, it is possible that there is a link between land use within a watershed and the chemical composition of the stream. The objectives of this study are to determine if varied land use does affect the concentrations of macronutrients and trace elements present in the streams of Northwest Arkansas, and if so, to determine what extent urban and agricultural development are responsible for these changes. Water samples were collected across 19 streams in the Northwest Arkansas region between January and March of 2022. Water samples …

Comparing Economics Of Traditional Carbonation Method And A Novel Carbonation Invention For Craft Beer, Kira Simonson
Biological and Agricultural Engineering Undergraduate Honors Theses
The traditional method for the carbonation of beer includes bubbling CO2 through a pressurized brite tank until the desired level of carbonation concentration is reached. The gas either dissolves in the liquid volume or passes through the beer into the gas headspace above the bulk volume of beer. The gas that passes through the liquid can strip the beer of flavors, and this undissolved gas is vented to the atmosphere. To reduce the gas lost to the atmosphere, the CO2 is dissolved into the beer slowly over a long period of time, which increases gas-use efficiency but sacrifices …
