2004 Projects

2004 - Diet Analysis
Diet Analysis of Nutrition Among College Students

This study examined the nutrient content of foods available at the Student Union. We performed a 24-hour food diary and analyzed the data with Food Processor software. The software analyzed for various nutrients including protein, fat, carbohydrates, vitamins, and minerals. It was found that most foods eaten at the Student Union produced diets that were nutritionally imbalanced. These results were variable depending on the different food choices students made.

2004 - Digital Imaging
Digital Imaging: New Technology Better Understood through Mathematics

The students of the Digital Imaging Research Group designed all six pages of the Four Corners section of this year's memory book. During the process, we learned how to take quality photos with digital cameras and then process them using imaging editing software. We learned the mathematical concepts and specific terminology appropriate for digital imaging. During this process, we were able to apply the mathematical concepts that we learned in order to produce high quality images.

2004 - Digital Video
Digital Video Production

In the video production class, students learned how to put together a promotional video for the Four-Corners, Upward Bound, and Nizhoni programs. The production process included pre-production, production, and post-production. In addition to producing a video, each student wrote a researched an occupation in the television industry, including Producing, Directing, Art Directing, Editing, Creating Special Effects, Lighting, Soundtrack Producing, and Acting.

2004 - Estimated Water Budget
Estimated Water Budget for the C Aquifer for the Little Colorado River Basin, NE Arizona

Groundwater levels in the Little Colorado River Basin are steadily declining, while the population is steadily increasing. Is the regional aquifer beneath the basin is in a state of dynamic equilibrium? Using the hydrologic equation we are attempting to answer this question. We calculated the average annual precipitation for the limited area of the basin that has the potential for direct recharge of the aquifer. We combined this with pumping and discharge data from previous studies. However, much of the required recharge and discharge data are either sparse or non-existent. Therefore, until more and better data become available, our best answer to this question can only be an estimate.

2004 - Web Development
Web Development

This research group developed and published a web site explaining the importance of accessible web development and proper accessible development technique. Poorly developed web pages include an abundance of un-necessary "tags" and a shortage of accessible coding which forces disabled users to try to sift through a large amount of un-necessary information and, in some cases, prevents the users from being able to navigate the site at all. Poorly developed web sites also contribute to slow download speeds, incorrect display of a website, and low rankings on search engines.

2004 - Uranium Estrogenicity
In Vivo Examination of Uranium Estrogenicity

In past studies, heavy metals, such as cadmium, have proven to act as an estrogen-contributing to many effects on the uterus. However, uranium has not been among the heavy metals tested for estrogenicity. Estrogen affects the uterus by increasing its weight and increasing its epithelial cell density. We hypothesize that uranium will effect the uterus by increasing uterine weight and increasing epithelial density. We tested our hypothesis by dosing female ovariectomized mice with uranyl nitrate and estrogen to examine the estrogen sensitive effects on the uterus. Uteri were collected from the mice, weighed, and histologically processed and examined. We found an increase in uterine weight in uranium and estrogen treated mice.

2004 - Microbes
Analysis of Microbes Found in Common Fruits and Vegetables

This experiment was conducted to estimate the number of microorganisms found in samples of broccoli, carrots, tomato, and lettuce from a local grocery store. Potato Dextrose Agar (PDA) was used to demonstrate carbohydrate nourishment and Nutrient Agar (NA) was used to demonstrate protein nourishment of microorganisms. Results after one week showed that the most numerous microorganisms grew from the carrot samples on both types of agar, and the least numerous grew from the tomato samples. Growth on the carbohydrate-based PDA plates tended to be higher than the protein-based NA plates with all vegetable samples.

2004 - Field Guide
Field Guide to the Plants of the Sinclair Wash and their Uses

In this study we collected and identified plants from Sinclair wash and put them into our own field guides. Sinclair wash is a perennial wash on the NAU campus with two habitat types. They are the wash and south-facing slopes. We collected plant specimens, took notes, made sketches, and discussed growth form, flower color, leaf shape and location of the plants. Then we put the dried flowers and information into our field guides. We researched the medicinal and edible properties of each plant. We learned that nearly all the plants we collected are edible or have medicinal uses.
