Analysis Of Tailpipe Particulate Matter Emission From A Sampling Of Kansas City Vehicles, Erika Louise Roesler
Analysis Of Tailpipe Particulate Matter Emission From A Sampling Of Kansas City Vehicles, Erika Louise Roesler
Master's Theses and Doctoral Dissertations
As the United States Environmental Protection Agency (EPA) seeks to model vehicle emissions based on dynamic engine operating conditions, modal PM datasets will be investigated for their robustness and limitations under the requirements of the EPA’s model: MOVES. The Kansas City PM Characterization Study tested more than 500 light-duty gasoline cars and trucks on a dynamometer in summertime and wintertime temperatures with four different modal PM2.5 instruments.
Using data reduction techniques used to prepare other datasets for the MOVES model, the modal PM data were analyzed to determine its ability to be incorporated into MOVES. It was found through averages …
Complexity Trends In The Evolutionary History Of Dasycladalean Algae, Michael Stearns
Complexity Trends In The Evolutionary History Of Dasycladalean Algae, Michael Stearns
Senior Honors Theses and Projects
Dasycladalean algae are a group of marine algae that have an excellent fossil record extending back more than 500 million years. In our study, we investigated morphological complexity over the evolutionary history of this group. To determine complexity for each of more than 400 species, we assigned numerical values for six morphological features; the sum for each species forms a quantitative expression of complexity. We found that although maximum complexity increased over time, forms with minimum complexity persisted during most of the evolutionary history of the group.
Implementation Of Labcreator And The Integration Of Cyberlab, Kang Zhao
Implementation Of Labcreator And The Integration Of Cyberlab, Kang Zhao
Master's Theses and Doctoral Dissertations
With the development of the World Wide Web, online courses are becoming more and more popular in modern science education. CyberLab aims to solve an important issue in distance science education -- laboratory experiments in online courses. It is a toolkit that handles creation, exportation, and execution of virtual experiments (within web browsers). It consists of LabCreator and LabExecutor. With LabCreator, instructors can create virtual experiments and export them into intermediate files. Students can download those files from online course websites and execute them in LabExecutor on their own computers.
The paper reports on the completion of two important tasks …
Synthesis And Analysis Of An Α-Amylase Inhibitor And An Antimicrobial Peptide, Brahmlin Kaur Sethi
Synthesis And Analysis Of An Α-Amylase Inhibitor And An Antimicrobial Peptide, Brahmlin Kaur Sethi
Senior Honors Theses and Projects
Abstract 1: α-Amylase is an important enzyme in the body responsible for hydrolyzing many polysaccharides such as dietary starch. Inhibition of this enzyme could be extremely beneficial in diabetic patients because it could lower the glucose levels in the blood. Our objective is to synthesize a small analog of a natural α-amylase inhibitor, Tendamistat. This molecule has 15-22 residue segment that are critical for its activity. The peptide was synthesized, cleaved, purified, analyzed, and an enzyme assay was run. Michaelis Menton and Lineweaver-Burk plots were constructed to determine the Vmax, Km, and Ki for each …

Surface Analysis Of A Black Coating From Little Lost River, Reshmi Perumplavil
Surface Analysis Of A Black Coating From Little Lost River, Reshmi Perumplavil
Master's Theses and Doctoral Dissertations
A black coating of unknown origin obscures the pictographs in Little Lost River Cave, Idaho. We utilized x-ray photoelectron spectroscopy (XPS) to characterize the outermost surface of the black coating to understand how it was formed. Carbon and oxygen predominated in the XP spectra, whereas nitrogen was detected at varying levels in different samples. High-resolution carbon 1s XP spectra showed that carbon was present in at least three different forms: hydrocarbon C, carbonyl C, and carbonate C/ amide C. The N 1s peak was observed at ~399-400 eV binding energy, which is usually attributed to aromatic or amide N. The …
