Title: Oxidation of Hydroquinones to Quinones with Hydrated silica gel and Sodium Periodate in Non-Aqueous Media
Major: Biology
Faculty Sponsor: Dr.
Mohammed Ali
Abstract:
Quinones play important roles in organic synthesis. A large number of quinones are biologically active and they are also used as
starting materials in complex organic synthesis. Quinones are generally
prepared by oxidizing hydroquinones with an oxidizing
reagent. A variety of oxidizing reagents have been reported in the literature
for this transformation. All reported oxidation reactions employed
aqueous-organic bi-phase media. Water is required since inorganic oxidizing
reagents utilized in this transformation are soluble only in water. Organic
reactions in aqueous media suffer from many disadvantages. Disadvantages, such
as, difficulty in product isolation from aqueous media, low solubility of
organic substrates in aqueous media, inefficient mixing of reagents during the
reaction, laborious work-up of the reaction, greater potential for workers to
come into the contact with toxic reagents during product extraction and
reaction workup steps, undesired participation of water in the reaction, lower
efficiency due to the loss of product, difficulty in work-up due to
emulsification are common. Waste water contaminated with the spent and
unrelated oxidizing reagents require treatment before releasing into the water
streams. We have developed a procedure in our laboratory that allows us to
carry out oxidation of various hydroquinones with
hydrated silica gel and sodium periodate. This
oxidation reaction can now be carried out in organic solvent that previously
required water. Our procedure does not suffer from a number of disadvantages
listed above. Results of our investigation will be presented at the meeting.

Title: To Study the Wavelength of a HeNe Laser
using Michelson
Inteferometry
Major: Engineering Physics and Physics
Faculty Sponsor: Dr. Jai N. Dahiya
Abstract: To study the wavelength of the HeNe laser
a Michelson interferometer, consisting of a lens, beam splitter, moveable
mirror, adjustable mirror, and viewing screen is used. The interferometer is an
outstanding device that splits a light beam into two parts and then recombines
these beams to form an interference pattern after they have traveled over
different paths. By moving the movable mirror the path length of one of the
beams can be varied. Since the beam
traverses the path between the movable mirror and the beam-splitter twice,
moving the moveable mirror ¼ wavelength nearer the
beam-splitter reduces the optical path of the beam by ½ wavelength. By doing this the interference pattern will
change. In addition to this the radii of the maxima will be reduced so they now
occupy the position of the former minima. By slowly moving the mirror a measured
distance d, and counting N, the number of times the fringes pattern is restored
to its origina

Title: Ordinal Position and Reward Memory Learning Effects in Animals
Major: Psychology
Faculty Sponsor: Dr. Richard Burns
Abstract: Two experiments
investigated the effects of denying response cues through placements in
training and in transfer tests on position-type and memory-type responding.
Experiment 1 investigated the apparent blocking effect of placements on
position responding indicated by prior studies (Goforth,
2002, 2003) while separating the effects of placements in training versus
transfer tests. Rats were trained on a reward/non-reward/reward (RNR) series
and shifted to NNN. Half were prevented from running on randomly selected
trials of each series in training only. Others were allowed to run on all
training trials and shifted with placements. Days 22-26 immediately preceding
transfer showed significant differences in trials, F(2,
20) = 71.83, p < .001, with slower running on Trial 2. On Transfer Days 27
and 28 the trials main effect remained significant F(2,
15) = 6.89, p < .01. Running on Trial 2 of the Transfer Test Days 27 (M =
1.27, SD = 1.10) and 28 (M = 1.45, SD = 1.25) was significantly faster than it
was on the two days prior to the test, Test Days 25 (M = 2.79, SD = 1.20) and
26 (M = 3.01, SD = 1.17). Results suggest that both significantly reduce
position-type responding, with no difference found between the two groups.
Experiment 2 further investigated the possible blocking effect of denying
response cues in training, again using a RNR series. An initial training period
with random placements was followed by a training period that restored response
cues (no placements). For the experimental Group 1, days 22-26 showed
significant differences in trials, F(2, 10) = 22.07, p
< .001, with slower running on Trial 2. Averaged for both groups, Days 42-46
showed a significant difference in trials, F(2,20) =
71.83, p < .001, with slower running on Trial 2. On subsequent transfer to
NNN on Day 47 the trials main effect remained significant for both groups
F(2,20) = 6.89, p < .001, again with slower running on Trial 2, indicating
strong position-type responding by retaining the fast-slow-fast response
patterns learned in training. No difference between the control and
experimental groups was found and no difference was found between the running
times on the five days immediately preceding the transfer and the running times
on transfer. Results

Title: Gene Expression in Coprinus cinereus in the Presence of Rapamycin
Major: Biology
Faculty Sponsor: Dr.Allen Gathman
Abstract: I am working on the project of finishing, annotating, and mapping the Coprinus cinereus genome. Specifically, I have been involved in the beginning stages of the process of isolating and sequencing cDNAs. C. cinereus is a characteristic basidiomycete that grows well in laboratory conditions. Research on C. cinereus can be applied to many commercially significant fungi. However, there are many gaps in the existing sequence for the organism. In this project, C. cinereus is being grown under assorted conditions, which will result in the expression of different genes for use in annotation. I have observed the growth of C. cinereus when treated with varying concentrations of rapamycin, an antibiotic that interferes with the TOR (target of rapamycin) signaling pathway. The effects of rapamycin on an organism generally resemble starvation responses, including blocking cell growth, inhibiting translation initiation, reducing the transcription of ribosomal protein rRNAs, and regulating phosphatates and amino acid permeases. The different mRNAs that C. cinereus transcribes while undergoing this treatment will ultimately be used in the construction of a plasmid library. I have been working to determine the concentration of rapamycin that causes discernable differences in mRNA transcription. After growing C. cinereus in various rapamycin concentrations, I extracted RNA from each sample and tested for purity. I then ran a gel electrophoresis and did a downward Northern blot of the RNA extracts. I have been probing this blot with various digoxygenin-dUTP-labeled DNA probes to determine the level of RNA transcription. Once I determine the rapamycin level at which a significant difference in mRNA transcription is produced, C. cinereus will be grown in larger quantities and mRNA purified from the total RNA will be used in making cDNAs for plasmid library.

Title: Archaeological Ethics and Repatriation
Major: Anthropology
Faculty Sponsor: Dr.Carol Morrow
Abstract: Archaeology, a sub-discipline of Anthropology, is the study of people and their material cultural remains. These material remains can include items as ordinary as the remains of buildings to other items such as skeletal remains and grave goods. These items, particularly the skeletal remains and grave items, are objects of great debate. The skeletal remains are the remains of humans and are considered sacred by their descendants, but at the same time can provide for a wealth of information about a culture and how the people within the culture lived their lives. An ongoing debate in archaeology is how to deal with these items, and has in recent years brought the debate over repatriation into such prominence that protests often find their way into the public eye. Repatriation is the legally mandated return of skeletal remains and sacred artifacts to the properly identified, legally recognized descendants of the remains. Repatriation, however, means that those studying the skeletal remains and artifacts lose their information base, leaving archaeologists without much needed data. This paper will discuss some of the relations between Archaeologists and Native Americans, using their positions towards the issue of repatriation to help describe the different groups and their stances. The topic of repatriation is used because is one topic that often leads towards heated discussion within the discipline and quite clearly draws the lines of how the actors within and in contact with archaeology feel towards each other and what their roles should be. Once these groups are outlined, a discussion of ethics will follow. The discussion will outline each group’s reasoning and their stances on general issues and specifically the issue of repatriation. The final portion of the paper is a brief discussion of possible solutions and compromises. While this paper focuses on North American Archaeology and Native Americans, the issues discussed have worldwide applications.

Title: A Non-Radioactive Method for Labeling and Detecting Nucleic Acids
Major: Biology
Faculty Sponsor: Dr. Walt Lilly
Abstract: This study focuses on an alternative method of labeling and detecting nucleic acids that does not involve the use of radioactive isotopes. The system under investigation involves the molecule Digoxigenin, which takes the place of the radioactive isotope Phosphorus-32. This method is being studied to determine its effectiveness for genomic work on the organism Coprinus cinereus. If the Digoxigenin system is determined to be as effective as its radioactive counterpart, then it will most likely be incorporated into future genomic studies. Initial results of the study have given promising results, even though testing is still being conducted.

Title: 1,3-DIBROMO-5,5-DIMETHYLHYDANTOIN: AN EFFICIENT REAGENT FOR OXIDATION OF SULFIDES TO SULFOXIDES IN NON-AQUEOUS MEDIA
Major: Chemistry
Faculty Sponsor: Dr. Ali
Abstract: We have utilized molecular bromine for oxidation of sulfides to sulfoxides and reported the results in the literature. However, molecular bromine is toxic and is very difficult to handle. Recently we have developed a method for oxidation of sulfides to sulfoxides utilizing hydrated silica gel and dibromohydantoin. Dibromohydantoin, a free-flowing light yellow solid acts as a source for electrophilic bromonium ion that plays a key role in this oxidation reaction. Dibromohydantoin is a safer alternative to toxic molecular bromine for oxidation of sulfides previously reported by us and others. It is noteworthy that our procedure allows the use of a non-aqueous media and does not require the presence of an acid scavenger. Silica gel removes the HBr produced in the reaction and prevents acid catalyzed side reactions. Results of our investigation will be presented at this meeting.

Title: Reflection and Transmission Holograms using a Helium-Neon Laser
Major: Engineering Physics
Faculty Sponsor: Dr. Jai N. Dahiya
Abstract: Holograms
are a way of creating an image of an object by using a fine pattern that shapes
a wavefront of light. This pattern is created from
interference between two beams of light and is recorded photographically on a
fine grain emulsion. In this experiment, the two beams of light that are used
are called the reference beam, which is shined directly onto the viewing plate,
and the object beam, which shines directly onto the object and scatters off of
the object on to the viewing plate. There are several types of holograms, but
most of these can be classified as one of two main groups: transmission, and
reflection. For this experiment we used a He-Ne laser

Title: Williams Syndrome: Patterns and Interventions
Major: Psychology
Faculty Sponsor: Dr. Gail Overbey
Abstract: Williams Syndrome is a rare genetic syndrome
characterized by a contradictory behavioral pattern, distinctive facial
features, developmental delay, early language delay
followed by a language spurt that leads to extraordinary language skills,
medical conditions such as cardiac difficulties and renal problems most likely
due to the abnormality of the elastin gene, and
cognitive abnormalities and distortions. It is caused by a micro-deletion on
the long arm of chromosome 7 which includes the elastin
gene (7q11.23). Testing for the syndrome is simple and accurate but most
children with Williams Syndrome do not receive the appropriate test and,
therefore, are often misdiagnosed with a variety of other disorders. Williams
Syndrome is a relatively newly discovered syndrome and research on the topic is
limited. The paper will focus on some of the behavior abnormalities seen in
children with Williams Syndrome. A variety of interventions for poor
adaptability, atypical activity, and anxiety will be discussed.

Title: Bragg’s Diffraction Using Microwaves
Major: Physics; Engineering Physics
Faculty Sponsor: Dr. Jai Dahiya
Abstract: A crystal is an ordered array of atoms or groups of atoms. When a system of waves is incident on a crystal, the atoms in these layers are capable of absorbing and immediately reradiating these waves. In effect, the waves reflect from these layers. Since path length will vary for rays reflected from the various layers, interference effects can occur. This experiment uses a Gunn Diode to produce microwaves and an artificial “crystal” of styrofoam and ball bearings to examine Bragg’s Diffraction, a method of determining interplanar distances in a crystal. By examining the varying intensities of the reflected beam of microwaves for different angles, we can graph the data in terms of angle vs. relative intensity. By examining the graph, we find the angle that has the highest intensity and its peak number and use this to find the distance between two parallel planes. With the macroscopic styrofoam “crystal” we can compare our experimental values of interplanar distance to known distances that we measured with a vernier caliper before the experiment. Repeating this for more than one crystal plane allows us to examine the effectiveness of this method for various angles.

Title: Parents' Influence on Their Children's Smoking

Abstract: The study that we performed was on the smoking habits of college students based on their parent’s smoking habits. There were 18 university students surveyed at the university. Out of the 18 students over half, 67%, do not smoke and chose not to because their parents did not smoke, or because there was a family history of smoking related illnesses. We also looked at the different parenting styles of the parents and found that most of the students had parents that used an authoritative style of parenting. We believe that if the parents are more involved with their child then the child would not smoke, the more lenient types of parents do not show that they care as much about their child or their child’s habits. The study also showed that children of parents who smoke tend to not smoke because their parents disapprove of smoking. Many parents who smoked did not want their children to follow in their footsteps and smoke.

Abstract: How people use religion or spirituality to cope with stress was
investigated. Using lower level psychology students as subjects, the study
Patterns of Positive and Negative Religious Coping with Major Life Stressors,
by Pargament, Smith, Koenig, and Perez (1998) was

between spirituality and the ability to cope, as well as significant positive
relationships between religion and coping with stress. However, among the 18
participants used in this study, there was a
non-significant correlation between religious activity and coping with stress;
nor was there a significant correlation between stress and spirituality. This
study has a possibility of providing sufficient results if other studies are

Title: Synthesis of a Potential Antihistamine
Major: Biology
Faculty Sponsor: Dr. Bruce Hathaway
Abstract: This
experiment was designed to test the suitability of synthesizing an
antihistamine-like compound from simple starting materials, namely benzoyl chloride, methoxybenzene
(anisole), and diethylaminoethanol. In the first
step, benzoyl chloride was reacted with methoxybenzene in the presence of aluminum chloride to
yield 4-methoxybenzophenone. This reaction was a standard Friedel-Crafts
acylation resulting in a 41.7% yield. The compound’s
identity was verified by carbon and hydrogen nuclear magnetic resonance (NMR)
spectra, infrared (IR) spectra, and melting point determination.
4-methoxybenzophenone was then reduced with sodium borohydride
to form 4-methoxybenzhydrol. This reaction yielded 54.5% of the theoretical
maximum, and the product’s identity was verified using IR spectra, which
indicated the presence of an alcohol, carbon and hydrogen NMR, thin-layer
chromatography (TLC), and melting point determination. The alcohol was then
reacted with dry hydrochloric acid to form 4-methoxybenzhydryl chloride in a
92.7% yield. Purification of this product proved infeasible; however, the
presence of the chlorine was verified by Beilstein’s
Test (flame test) and the absence of the alcohol was verified by IR spectra.
Part of the product of this reaction was then combined with diethylaminoethanol
and allowed to react. The compound diethyl{2-[(4-methoxyphenyl)phenylmethoxy]ethyl}amine, the target antihitamine-like
compound, was obtained from this reaction.

Abstract: This study was conducted in order to examine past and present eating habits. We handed out the Eating Habits Survey by Byrne and Kelley (1981), which looked at past eating habits (habits that come from the family) and present habits (those that they have now about eating). The independent variables were past and present eating habits and the dependent variable was the average of the female and male past habits and the female and male present habits about eating. The responses were then calculated and averaged to find that female scores were higher on both past and present habits. Females had higher averages than males. The results of the past attitudes section suggested that parents of females might be more overweight than the parents of males. Females had a more ideal view (they knew they were overweight more of the time) of their bodies whereas males were more distorted thinking that they were in a normal weight range when they were really overweight.

Title: Teachers' Vocal Variety and Children's Responses to Guidance and Instruction in Early Childhood Classrooms
Major: Child Development
Faculty Sponsor: Dr. Carolyn Cogswell
Abstract: Research on the effects of caregiving style have demonstrated the respectivre effects of high or low levelsof demandingness or responsiveness on children's behavioral outcomes. Children whose parents, teachers, or caregivers are warm, consistent and involved are more likely to exhibit prosocial behavior than are children who are treated with harshness, punitiveness or overcontrol. Diana Baumrind (1971, 1993) has identified two dimensions of caregiving style--demandingness and responsiveness. High or low levels of these dimensions combine to create either authoritarian, authoritative or permissive patterns of parenting or caregiving. High levels of demandingness and high levels of responsiveness produce the optimally effective caregiving style referred to as the authoritative parenting style. One element of responsiveness (e.g., warmth, nurturance) is vocal variety, which varies according to volume, pitch, rate or quality, and may anecdotally be referred to as "tone of voice." In the university lab school of a rural midwestern university, three classroom teachers aare being observed in three different classrooms respective to the type of compliance resulting from the children when verbal instruction or guidance is given. A number of possible responses sto this instruction or guidance have been identified as ignoring, resisting, comliance with positive affect and comopliance with negative affect. The vocal variety of the three teachers and the type of responses of the children are being monitered and recorded in an observational comparative study. Results and implications for practice will be discussed.

Title: Efficacy of
Thermochron iButtons for Assessment of Nest Box Occupancy by Sciurids.
Major: Biology
Faculty Sponsor: Dr. John Scheibe
Abstract: We used Thermochron iButtons as remote
time/temperature data loggers. We
mounted 2 iButtons on each of 28 flying squirrel nest boxes. The iButtons were programmed to record temperatures
once every 20 minutes over a period of 28 days.
After 28 days, the data were downloaded, and the iButtons were
reprogrammed and redeployed. By
comparing the interior and exterior temperatures of experimental and control
nest boxes, we were able to determine which nest boxes were used and when they
were used. Furthermore, we were able to
differentiate between the temperature profiles of nest boxes used by southern
flying squirrels and gray squirrels.
Because of their low cost and ability to record near continuous
time/temperature data, iButtons provide a powerful tool for monitoring habitat
use and activity data for sciurids.
