Confessions of a Eurekan! Pioneer or
“Why my summer didn’t suck too bad”
Uri “Cap” Rogram and Professor Calhounan Orscollage
Abstract This describes what I thought I would be doing and what my Advisor told me would result. As you look over this poster, you should probably conclude that advisors don’t know much. Introduction As far as I can tell a lot of work has been done on the problem to be studied, but the results thus far have not agreed with my advisor’s pet theories (he keeps babbling about a boat and a rock – Geez!), so we’re going to keep at it, until they do.
Methods Taken from the journal, Arcania Esoterica, the methods used in this study are like something from the dark ages. When I told my Mom what I was doing, she said that she had just seen an episode of Oprah, which reported that three people dropped dead, doing exactly the same thing. She wants me to come home immediately. Now I want to stay! Results The numbers and observations reported below are mostly either made up or were told to me by my graduate student. I’ve never seen a person with bigger eyes or pastier skin. Don’t they ever let these people outside?
Discussion My advisor says that if we look at the results correctly (like standing on our heads looking in a mirror), they may overturn one hundred years of accepted fact. “Right.” Conclusions All in all it was a great summer. I got to go to Carowinds, whitewater rafting, a Drive game, learned that the fate of humanity depends on my having taken folic acid since the day I was born (who eez this folic acid, anyway?), and a bunch of other fun stuff. Research was way more fun than I expected, in fact I think I’ll keep working with my advisor and maybe win an award some day. My Mom will like that.

Oklahoma is the 20th-largest state in the United States, covering an area of 69,898 square miles (181,035 km!), with 68,667 square miles (177847 km!) of land and 1,231 square miles (3,188 km!) of water.[14] It is one of six states on the Frontier Strip, and lies partly in the Great Plains near the geographical center of the 48 contiguous states. It is bounded on the east by Arkansas and Missouri, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, and on the south and near-west by Texas.[edit] TopographySee also: Lakes in Oklahoma Oklahoma is situated between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed,[15] generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary.[16][17] Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, OK, which dips to 289 feet (88 m) above sea level.[18] A river carves a canyon in the Wichita Mountains. Among the most geographically diverse states, Oklahoma is one of four to harbor more than 10 distinct ecological regions, with 11 in its borders — more per square mile than in any other state.[9] Its western and eastern halves, however, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight ecological regions and its western half contains three.[9] The Ouachita Mountains cover much of southeastern Oklahoma. Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains.[16] Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains mark the only major mountainous region between the Rocky Mountains and the Appalachians.[19] A portion of the Flint Hills stretches into north-central Oklahoma, and in the state's southeastern corner, Cavanal Hill is regarded by the Oklahoma Tourism & Recreation Department as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.[20] The semi-arid high plains in the state’s northwestern corner harbor few natural forests. Oklahoma there is a rolling to flat landscape with intermittent canyons and mesa ranges like the Glass Mountains. Partial plains interrupted by small mountain ranges like the Antelope Hills and the Wichita Mountains dot southwestern Oklahoma, and transitional prairie and woodlands cover the central portion of the state. The Ozark and Ouachita Mountains rise from west to east over the state's eastern third, gradually increasing in elevation in an eastward direction.[17][21] More than 500 named creeks and rivers make up Oklahoma's waterways, and with 200 lakes created by dams, it holds the highest number of artificial reservoirs in the nation.[20] Most of the state lies in two primary drainage basins belonging to the Red and Arkansas rivers, though the Lee and Little rivers also contain significant drainage basins.[21] [edit] Flora and fauna Populations of American Bison inhabit the state's prairie ecosystems. Forests cover 24 percent of Oklahoma[20] and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses.[22] Where rainfall is sparse in the western regions of the state, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the far western reaches of the panhandle.[22] Marshlands, cypress forests and mixtures of shortleaf pine, loblolly pine and deciduous forests dominate the state's southeastern quarter, while mixtures of largely post oak, elm, white cedar (Thuja) and pine forests cover northeastern Oklahoma.[21][22][23] The state holds populations of white-tailed deer, coyotes, bobcats, elk, and birds such as quail, doves, cardinals, bald eagles, red-tailed hawks, and pheasants. In prairie ecosystems, american bison, greater prairie-chickens, badgers, and armadillo are common, and some of the nation's largest prairie dog towns inhabit shortgrass prairie in the state's panhandle. The Cross Timbers, a region transitioning from prairie to woodlands in Central Oklahoma, harbors 351 vertebrate species. The Ouachita Mountains are home to black bear, red fox, grey fox, and river otter populations, which coexist with a total of 328 vertebrate species in southeastern Oklahoma. Also, in southeastern Oklahoma lives the American Alligator.[22] Oklahoma also contains the largest Mountain Lion population in America, with sightings being reported in every county since 2002, with an increasing number of confirmed sightings occurring on the outskirts of major metropolitan areas including Oklahoma City, Tulsa, Stillwater and Lawton.[citation needed] [edit] Protected lands Mesas rise above one of Oklahoma's state parks. Oklahoma has 50 state parks,[24] six national parks or protected regions,[25] two national protected forests or grasslands,[26] and a network of wildlife preserves and conservation areas. Six percent of the state's 10 million acres (40,000 km!) of forest is public land,[23] including the western portions of the Ouachita National Forest, the largest and oldest national forest in the Southern United States.[27] With 39,000 acres (158 km!), the Tallgrass Prairie Preserve in north-central Oklahoma is the largest protected area of tallgrass prairie in the world and is part of an ecosystem that encompasses only 10 percent of its former land area, once covering 14 states.[28] In addition, the Black Kettle National Grassland covers 31,300 acres (127 km!) of prairie in southwestern Oklahoma.[29] The Wichita Mountains Wildlife Refuge is the oldest and largest of nine national wildlife refuges in the state[30] and was founded in 1901, encompassing 59,020 acres (238.8 km!).[31] Of Oklahoma's federally protected park or recreational sites, the Chickasaw National Recreation Area is the largest, with 9,898.63 acres (18 km!).[32] Other sites include the Santa Fe and Trail of Tears national historic trails, the Fort Smith and Washita Battlefield national historic sites, and the Oklahoma City National Memorial.[25]
Oklahoma is located in a temperate region and experiences occasional extremes of temperature and precipitation typical in a continental climate.[33] Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold and warm air masses producing severe weather.[18] An average 54 tornadoes strike the state per year—one of the highest rates in the world.[34] Because of its position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely between relatively short distances and can change drastically in a short time.[18] As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 °F in the afternoon (the record high for that date), then an incoming squall line resulted in a drop to 17 °F at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same day.[35]
The humid subtropical climate (Koppen Cfa) of the eastern part of Oklahoma influenced heavily by southerly winds bringing moisture from the Gulf of Mexico, but transitions progressively to a semi-arid zone (Koppen BSk) in the high plains of the Panhandle and other western areas from about Lawton westward less frequently touched by southern moisture.[33] Precipitation and temperatures fall from east to west accordingly, with areas in the southeast averaging an annual temperature of 62 °F (17 °C) and an annual rainfall of 56 inches (1,420 mm), while areas of the panhandle average 58 °F (14 °C), with an annual rainfall under 17 inches (430 mm).[18] All of the state frequently experiences temperatures above 100 °F (38 °C) or below 0 °F ("18 °C),[33] and snowfall ranges from an average of less than 4 inches (10 cm) in the south to just over 20 inches (51 cm) on the border of Colorado in the panhandle.[18] The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Branch, all part of the National Weather Service and located in Norman.[36] Oklahoma's highest recorded temperature of 120 °F (49 °C) was recorded at Tipton on June 27, 1994 and the lowest recorded temperature of "31 °F ("35 °C) was recorded at Nowata on February 10, 2011. )

Abstract
Ceramic oxide particles have been melted and studied to describe surface or catalytic absorption properties of single crystal substrates. The experiment is designed to monitor contact angle evolution during temperature change in order to confirm whether or not a “complete wetting” scenario can be observed. This would mean that the contact angle becomes zero, producing a film. Energy input is used to overcome the surface tension between the particle and the substrate, allowing for a description of the surface or interface force. This is useful in determining catalytic and other properties of ceramic oxides at high temperatures. Ridge formation is believed to be the main source of interference.

Figure 1: Diagram of wetting experiment. In grey, the substrate. In blue, the molten oxide as bulk liquid with contact angle and surrounding film.
! Prepare the oxide substrate through ultrasonic cleaning. ! Select particle of a different ceramic oxide of appropriate size. ! Place particle on the substrate, and load into top or side view furnace
apparatus with inert atmosphere. ! Monitor the particle. At the first sign of the melting, begin high
resolution documentation at regular intervals until such documentation is futile. This occurs at high temperatures where evaporation becomes a significant force in the wetting process.
! Set the furnace to cool down and continue to document at regular intervals until resolidification occurs.
! Once all photo documentation is complete, begin analysis: For the side view: Draw a tangent line at the droplet interface and measure its constituent horizontal and vertical components. Calculate the contact angle by using the Arc Tangent Function. For the top view: provided the droplet is circular, measure its diameter.
! Once the data is gathered, graph and determine trends to illustrate the wetting behavior of the oxide particle on its substrate.
Figure 2: (Left) Top view of molten Zinc Oxide with a line drawn for diameter measurement. (Right) Side view of molten Aluminum Oxide with triangle drawn for contact angle measurement.
! There is a linear relationship between temperature and recorded values
! At high temperatures, values approach a constant value, deviating from the previous trend.

Trials have not achieved complete wetting, they instead assume a constant value. This suggests that if a complete wetting is possible, it will be difficult to attain, most probably because of ridge formation at the triple point.
Exploration of ceramic oxide properties at high temperatures is necessary to understand applications that may be useful in developing a variety of fields. Even data from mistakes is kept for later study, because a mistake today, may be the key to tomorrow's advancement.
Figure 4: A sample of the beautiful anomalies of this project. Their presence underscores the purpose of the experiment and may have an unknown importance all their own.

The Animated Work Environment (AWE) team aspires to create a versatile, user friendly environment for the home or small business through a collaboration of architecture, robotics, engineering, and psychology. As the EUREKA! Program started, the first stage of the project was coming to a close with the completion of a hinged prototype of the first four panels of the movable display structure by July 27, 2007. Concurrently, progress was underway for a desk design to adjust to the needs of the user: from individual work to presentations to recreational gatherings. By the third of August, 2007, plans were set to begin cutting the desk prototype from !” plywood at the start of the Fall Semester. As the EUREKA! Program comes to a close, the AWE team begins to research the various computers, flat screen monitors, and accessories to obtain a user friendly environment.
How can a work environment be created that is versatile and user friendly? • Versatility 1. Meetings 2. Gaming 3. Presentations 4. Composition 5. Viewing • User Friendly 1. Wireless technology 2. Six preset configurations 3. Moveable desk with three separable work
stations
Abstract
Introduction
As this is a multi-disciplinary project comprised of several smaller tasks with cooperation among team members from several different departments and degree levels, it was imperative that the desk design and the wireless technology meet the specifications and the approval of every team member.
The desk started out as a more geometric shape; however, after every meeting, the desk took on more and more complex curves to accommodate for user comfort and ease while still maintaining a clean, architecturally pleasing style.
The search for computer technology was no less complex. The monitors and their mounts for the work station wall had to meet weight specifications, 40 pounds total, and still be functional as well as be VESA, mounting standards, compatible. The mouse and keyboard had to be wireless as well as reliable in their responses. The CPU had to be ideal for gaming but still well equipped for composition and collaboration.
Method
In the end, the desk was rather amorphous with three moveable sections.
This project is meant to bring the technology that is available to the major corporations to the small business and the homeowner on a smaller scale. Should the Animated Work Environment pass the usability testing. This research project will have succeeded in bringing a versatile, electronic medium to the masses, thus allowing for gamers, entrepreneurs, students, and at-home businessmen to all use the same space and computer systems for radically different uses.
As this project is still a work in progress, it is to soon to have a definite conclusion. The usability testing of the Animated Work Environment will begin in about a month, hopefully by mid-September, at which time there will be conclusive evidence as to whether or not the Animated Work Environment is functional.

Results Continued
The monitors are to be 19 inch flat screens with custom made mounts in order to better control weight and torque with the motors. The mouse and keyboard are wireless pieces by Microsoft with an ergonomic design. Finally, the CPUs are to be custom built to eliminate excess software and streamline the design to fit in the slots designed for the units.

Nutrient Intake and Health of Dominican Children Tyler Anne Hassenfeldt, College of Business and Behavioral Sciences Dr. Beth Kunkel, Professor of Food Science and Human Nutrition, and Mrs. Beth Wall, Food Technology Student
The aim of this study was to compare how the nutrient intake in Dominica changes as the country becomes more Westernized and leaves its indigenous roots behind. The influence of the Carib Indians is still visible in the foods that are eaten on the island today. The original set of data was collected in the fall of 2005, and a second set of data will be recorded in the fall of 2006 on a return trip to Dominica.
Abstract
Introduction The ten villages in Dominica that were studied were:
• Three villages along the northern tip of the island (Pennville, Vieille Case, and Thibaud)
• Two villages in the Carib Indian reservation area (Salybia and Sineku)
• Five villages along the south-eastern coast (La Plaine, Boetica, Delices, Petite Savanne, and Bagatelle)
The heights, weights, and skinfold thicknesses (a measure of overall body fat) of 135 Dominican schoolchildren from ages 5 to 14 were measured and recorded. The children were also asked to recall all of the foods they had eaten in the last 24 hours, including meals, drinks and snacks. Each child was asked to have a parent fill out a survey relating to the study. The survey included questions about food availability and preparation as well as other health-related issues. Back in the U.S., Body Mass Indexes (BMIs) were calculated for each child according to a formula which took into account height, weight, age and gender. The same formula also generated a percentage that showed how a child’s BMI compared to other children of the same age and gender.
Methods
Sample Survey Questions Where do you get your drinking water from? Own tap, inside the house – 21.6% Own tap, outside the house – 21.6% Stand pipe – 44.6% Water tank – 0.6% River or lake – 3.4% Spring – 6.0% Buy Water – 0.6% No response – 1.3% Do you grow your own food in a home garden or fish or hunt for your food? Yes – 60.0% No – 25.2% No response – 14.8%
Did your household ever run out of money to buy food? Daily – 8.9% Weekly – 17.8% Monthly – 14.1% Seldom – 29.6% Never – 25.2% No response – 0.4% Which of the following do you normally use for cooking? Wood fire – 41.8% Coal pot/Coals – 11.6% Gas stove – 46.5% Electric stove – 0%
Average heights, weights, skinfold thicknesses, body mass indexes, and growth percentiles were calculated for each of the ten villages. The averages for all of the villages together were also calculated and are displayed below.

Shown below are the extremes for each category and the village from where each extreme came from.
As shown from samples of the twenty-four hour recalls, Dominican children have begun to eat more Westernized food. While the children continue to eat traditional foods, such as fish, chicken, dumpling soup, rice and beans, root vegetables and tropical fruit juices, new processed foods are gradually being incorporated into their diets as well. Some of these newer foods include packaged chips and cookies, soda, peanut butter, hot dogs, popcorn and Kool-Aid. As this project continues, the specific nutrients within each of the foods that was recalled by the children will be organized by a software program called Genesis. Generalizations about the specific nutrient intake of the children, the villages and the country as a whole will be able to be made. These generalizations can be compared to the information gathered about the heights, weights and BMIs of the children in order to see how much of an impact the foods these children eat has on their health.
