Bringing The Endangered Barn Owl Back To Mclean County, Illinois: Implementing A Local Nest Box Program, Anna Groves '11
Bringing The Endangered Barn Owl Back To Mclean County, Illinois: Implementing A Local Nest Box Program, Anna Groves '11
Outstanding Senior Seminar Papers
Barn owls are an endangered species in Illinois, but populations have been known to increase where nest box programs have been implemented. In conjunction with the John Wesley Powell Audubon Society, a barn owl nest box program was established in McLean County and the surrounding area. Seventeen boxes are now scheduled for construction and installation this winter in the McLean County area in order to enhance existing barn owl populations, and the nest box program will continue in the future through the JWP Audubon.
Technology Integration In Secondary Mathematics Classrooms: Effect On Students’ Understanding, Megan Sheehan, Leah Nillas
Technology Integration In Secondary Mathematics Classrooms: Effect On Students’ Understanding, Megan Sheehan, Leah Nillas
Scholarly Publications
Technology use in secondary mathematics courses has the potential to bring about broad changes in learning environment and teaching pedagogy, allowing students to communicate and collaborate in new ways and to conjecture, justify, and generalize findings. However, this potential is only realized when teachers use technology in ways encouraging these outcomes (Galbraith, 2006). The purpose of this study is to examine the integration of technology in secondary mathematics classrooms and to evaluate the effectiveness of its use in relation to students’ learning outcomes. This self study research was conducted in honors geometry and AP calculus classes. Data sources included transcripts …

This study examines the environmental justice concerns in relation to minority involvement in environmental work; environmental concerns among minorities; and environmental outreach to minorities and low-income people. This project reveals that regardless of race, all people share environmental concerns; however, the kinds of concerns may differ. The culmination of this project provides suggestions for how the Ecology Action Center can …
Boundary Type Quadrature Formulas Over Axially Symmetric Regions, Tian-Xiao He
Boundary Type Quadrature Formulas Over Axially Symmetric Regions, Tian-Xiao He
Scholarship
A boundary type quadrature formula (BTQF) is an approximate integration formula with all its of evaluation points lying on the Boundary of the integration domain. This type formulas are particularly useful for the cases when the values of the integrand functions and their derivatives inside the domain are not given or are not easily determined. In this paper, we will establish the BTQFs over sonic axially symmetric regions. We will discuss time following three questions in the construction of BTQFs: (i) What is the highest possible degree of algebraic precision of the BTQF if it exists? (ii) What is the …

Honors Projects
Research in our group focuses on environmentally friendly organic synthesis using bismuth compounds. With increasing environmental concerns, the need for environmentally friendly organic synthesis following Green Chemistry principles has assumed increased importance. The Pollution Prevention Act, passed in 1990, was especially important in increasing an interest in Green Chemistry, which is the design and redesign of chemical processes with a view of improving safety. Our group focuses on synthetic methodology i.e. the transformation of one functional group to another. Such transformations are of special relevance in the pharmaceutical industry for manufacture of life saving drugs. Many of the current organic …

Optimization And Analysis Of A Robotic Navigational Algorithm, Derek Carlson, Joshua Brown Kramer, Faculty Advisor
John Wesley Powell Student Research Conference
The problem of robot navigation involves planning a path to move a robot from a start point to a known target point within an obstacle course. The efficiency of such an algorithm can be measured in several ways. For instance, Lumelsky and Stepanov measure the length of the path taken in terms of obstacle perimeters. Gabriely and Rimon compare their two-dimensional algorithm's efficiency to that of the optimal algorithm. Brown Kramer and Sabalka expand upon the work of Gabriely and Rimon to produce an algorithm for dimensions greater than two. The primary objective of this research was to implement improvements …

A Mild And Chemoselective Method For The Deprotection Of Tert-Butyldimethylsilyl (Tbdms) Ethers Using Iron(Iii) Tosylate As A Catalyst, Ram Mohan, Jason Bothwell, Veronica Angeles, James Carolan, Margaret Olson
A Mild And Chemoselective Method For The Deprotection Of Tert-Butyldimethylsilyl (Tbdms) Ethers Using Iron(Iii) Tosylate As A Catalyst, Ram Mohan, Jason Bothwell, Veronica Angeles, James Carolan, Margaret Olson
Scholarship
The most common method for the deprotection ofTBDMS ethers utilizes stoichiometric amounts of tetrabutylammonium fluoride, n-Bu4N+F(TBAF), which is highly corrosive and toxic. We have developed a mild and chemoselective method for the deprotection ofTBDMS, TES, and TIPS ethers using iron(III) tosylate as a catalyst. Phenolic TBDMS ethers, TBDPS ethers and the BOC group are not affected under these conditions. Iron(III) tosylate is an inexpensive, commercially available, and non-corrosive reagent.

Bismuth(Iii) Bromide In Organic Synthesis. A Catalytic Method For The Allylation Of Tetrahydrofuranyl And Tetrahydropyranyl Ethers, Ram Mohan, Scott Krabbe, Veronica Angeles
Scholarship
A bismuth bromide-catalyzed (10.0 mol %) multicomponent reaction involving the allylation of THF- and THP-ethers, followed by in situ derivatization with acetic anhydride to generate highly functionalized esters has been developed under solvent-free conditions. To the best of our knowledge, this is the first report of a catalytic procedure for the allylation of THF- and THP-ethers to yield ring-opened products.

Iron(Iii) Tosylate-Catalyzed Deprotection Of Aromatic Acetals In Water, Ram Mohan, Margaret Olson, James Carolan, Michael Chiodo, Phillip Lazzara
Scholarship
The deprotection of aromatic as well as conjugated acetals and ketals in water is catalyzed by iron(III) tosylate (1.0–5.0 mol %). Iron(III) tosylate is an inexpensive and readily available catalyst. The use of water, the most environmentally benign solvent, makes this procedure especially attractive for acetal deprotection.
Categorical Approaches To Non-Commutative Fuzzy Logic, Lawrence Stout
Categorical Approaches To Non-Commutative Fuzzy Logic, Lawrence Stout
Scholarship
In this paper we consider what it means for a logic to be non-commutative, how to generate examples of structures with a non-commutative operation * which have enough nice properties to serve as the truth values for a logic. Inference in the propositional logic is gotten from the categorical properties (products, coproducts, monoidal and closed structures, adjoint functors) of the categories of truth values. We then show how to extend this view of propositional logic to a predicate logic using categories of propositions about a type A with functors giving change of type and adjoints giving quantifiers. In the case …

We present a study of the cosmic infrared background, which is a measure of the dust obscured activity in all galaxies in the Universe. We venture to isolate the galaxies responsible for the background at 1mm; with spectroscopic and photometric redshifts we constrain the redshift distribution of these galaxies. We create a deep 1.16mm map (sigma ~ 0.5mJy) by combining the AzTEC 1.1mm and MAMBO 1.2mm datasets in GOODS-N. This combined map contains 41 secure detections, 13 of which are new. By averaging the 1.16mm flux densities of individually undetected galaxies with 24um flux densities > 25uJy, we resolve 31--45 per …

Molecular ions play a pivotal role in the chemistry of the interstellar medium due to their high reactivity even at low temperature. To identify these ions in interstellar space, it is essential to obtain high resolution laboratory spectra of potential interstellar ions for comparison to observational data. At the University of Illinois, we are developing a Sensitive, Cooled, Resolved Ion BEam Spectrometer (SCRIBES) that will allow us to obtain high resolution infrared direct absorption spectra of rotationally cold molecular ions in the absence of neutral molecules. This instrument can overcome many of the problems that arise when using other spectroscopic …
A Categorical Semantics For Fuzzy Predicate Logic, Lawrence Stout
A Categorical Semantics For Fuzzy Predicate Logic, Lawrence Stout
Scholarship
The object of this study is to look at categorical approaches to many valued logic, both propositional and predicate, to see how different logical properties result from different parts of the situation. In particular, the relationship between the categorical fabric I introduced at Linz in 2004 and the Fuzzy Logics studied by Hajek (2003) [5], Esteva et al. (2003) [1], and Hajek (1998) [4], comes from restricting the kind of structures used for truth values. We see how the structure of the various kinds of algebras shows up in the categorical logic, giving a variant on natural deduction for these …
When Does A Category Built On A Lattice With A Monoidal Structure Have A Monoidal Structure?, Lawrence Stout
When Does A Category Built On A Lattice With A Monoidal Structure Have A Monoidal Structure?, Lawrence Stout
Scholarship
In a word, sometimes. And it gets harder if the structure on L is not commutative. In this paper we consider the question of what properties are needed on the lattice L equipped with an operation * for several different kinds of categories built using Sets and L to have monoidal and monoidal closed structures. This works best for the Goguen category Set(L) in which membership, but not equality, is made fuzzy and maps respect membership. Commutativity becomes critical if we make the equality fuzzy as well. This can be done several ways, so a progression of categories is considered. …
