Pursuit Of A Chiral Amino Aldehyde Intermediate In The Synthesis Of (+)-Obafluorin, A B-Lactone Antibiotic, Jim Cwik '96
Pursuit Of A Chiral Amino Aldehyde Intermediate In The Synthesis Of (+)-Obafluorin, A B-Lactone Antibiotic, Jim Cwik '96
Honors Projects
This research is focused on synthesizing a chiral amino aldehyde from L-Serine. The proposed synthesis of the amino aldehyde would yield a stereochemically pure product working through an L-Serine beta-lactone intermediate. The amino aldehyde is a proposed intermediate in the synthesis of (+)-obafluorin, a beta-lactone antibiotic of interest. The proposed synthesis might provide a simpler, more versatile way to synthesize obafluorin.
Toward An Efficient Method Of Detecting Cocaine Metabolite In Urine, C.J. Summers '96
Toward An Efficient Method Of Detecting Cocaine Metabolite In Urine, C.J. Summers '96
Honors Projects
The primary metabolite of cocaine is benzoyl ecognine (BE). A desirable method for detecting cocaine use is the extraction of BE from urine into an organic phase solvent and subsequent analysis by High Performance Liquid Chromatography (HPLC). The attempt to develop such a method is hindered by the extreme water solubility of BE, making extraction into an organic phase extremely difficult. The present study attempts to use an ion-pairing agent to bind with BE and form a large, organically soluble ion-pair. The ion pairing agent used was Reinecke Salt in a I% solution. An aqueous solution of 50 ug/mL BE …
Powerfaids: Building A Road To Financial Aid Efficiency, Lauri Nichols '96
Powerfaids: Building A Road To Financial Aid Efficiency, Lauri Nichols '96
Honors Projects
To most students, the Financial Aid office is a small room in the basement of Holmes Hall where they are occasionally sent to sign over a paper or two. It has something to do with money, and every so often, these students get something in the mail that tells them just how much it's going to cost them to continue their education here at Illinois Wesleyan. They know that papers are filled out, usually by their parents, and then in a couple of months, a figure jumps out of nowhere and becomes "Your Financial Aid Package."

Improved Data Migration And Processing For Projecting The Financial Aid Budget, Jeffery L. Olson '96
Honors Projects
Last fall, I again resumed work on the budget projection model that encompassed five spreadsheets. Four of these sheets generated a set of statistical averages for each class. Each one consisted of 101 columns containing data for the four-to five-hundred students(rows) in each class. In addition, a fifth sheet used these averages to generate a highly accurate prediction for expenditures in the upcoming year. However, there were two main areas of improvement that became readily apparent: importing data and the sheets themselves.
The Synthesis Of An Organophosphorus Analog Of Acetylcholine, Jay-James R. Miller '96
The Synthesis Of An Organophosphorus Analog Of Acetylcholine, Jay-James R. Miller '96
Honors Projects
Acetylcholine (ACh) is the most widely studied of all neurotransmitter substances. For normal nerve function, the enzyme acetylcholinesterase (AChE) must hydrolyze ACh into its basic chemical constituents, choline and acetate. AChE is readily inhibited by organophosphorus (OP) compounds like sarin and soman--both nerve gases--as well as various pesticides. OP compounds also have been widely used to study the mechanism of ACh hydrolysis via AChE. In the 1980s, two studies using OP inhibitors examined the stereoselectivity of AChE hydrolysis. However, they yielded conflicting results. Hence, it is hoped that new studies with a novel OP compound will provide definitive information about …
The B-Spline Wavelet Recurrence Relation And B-Spline Wavelet Interpolation, Patrick J. Crowley '96
The B-Spline Wavelet Recurrence Relation And B-Spline Wavelet Interpolation, Patrick J. Crowley '96
Honors Projects
In most signal processing applications, a given range of data is best described by a set of local characteristics as opposed to a single global characteristic. In image processing, for example, a region of an image that contains numerous edges is best described as a region whose pixel color values change abruptly, i.e., they are not continuous values of color. A region of constant color, or gradually changing color, is best described as a region whose pixel values are constant, or whose values increase linearly by some factor. It is advantageous to represent this data with signals capable of adapting …
Macroelements And Orthogonal Multiresolutional Analysis, Jonathan M. Corbett '96
Macroelements And Orthogonal Multiresolutional Analysis, Jonathan M. Corbett '96
Honors Projects
Orthogonal multiresolutional wavelet analysis in a two dimension setting furnishes a basis for wavelet analysis. Bernstein-Bezier polynomials over simplexes provide elegant expressions of the necessary and sufficient conditions for a shift invariant space generating an orthogonal multiresolution analysis.
