Show moreThe Smithsonian Marine Ecosystems Exhibit’s mission is, “To inspire appreciation and understanding of the importance and complexity of marine ecosystems and the process of science through engaging exhibits, meaningful education, and the dissemination of Smithsonian Marine Station research.” Starting from the bottom of the food web, the exhibit recreates habitats for their resident organisms. Healthy phytoplankton cultures feed the oysters’ and their reefs’ filter feeding inhabitants like feather duster worms, sponges, and tunicates. Phytoplankton also plays a key role in maintaining water quality by consuming nitrates and phosphorous. This project focused on and tested different light sources in order to maximize phytoplankton production. Successful maintenance of Isochrysis galbana made it possible to replicate and thoroughly test phytoplankton production in relation to the light spectrum. Nannochloropsis oculata and Chaetocerous gracilis were unsustainable and must be further assessed for harmful cellular organisms specific to these species, contamination, and other variables that may be attributing to cell culture crashing.

- Correlation between size and home range of Agama agama africana.
- Abstract/Description
-
Agama agama africana is a lizard originally found in sub-Saharan Africa. Typically, it is found in urban and suburban areas and certain wildlands of Africa. This lizard was first noted in 1983 in Florida by L. D. William and L. Portis. It is believed that the Florida populations of these lizards are a result of intentional release and from damage done to exotic reptile businesses during Hurricane Andrew. Other researchers have documented that this species of lizard has a territory range that...
Show moreAgama agama africana is a lizard originally found in sub-Saharan Africa. Typically, it is found in urban and suburban areas and certain wildlands of Africa. This lizard was first noted in 1983 in Florida by L. D. William and L. Portis. It is believed that the Florida populations of these lizards are a result of intentional release and from damage done to exotic reptile businesses during Hurricane Andrew. Other researchers have documented that this species of lizard has a territory range that it aggressively defends against when other males challenge the territory. The behavior of the lizard was the focus for this study. Data was collected in areas throughout Jensen Beach and Stuart, Florida where populations are prevalent. Five males of A. a. africana were caught, marked with nail polished, and measured. Once released, three of these males and one uncaught male were observed from a distance while their movement and activity were recorded. Measurements were then taken of the lizards’ movement and the total area was calculated using an online irregular polygon calculator. Due to the small sample size, the results were inconclusive for a relationship between lizard size and home range area.

- Burn Wound Covers, Pretreatments, and Immunological and Microbial Concerns.
- Abstract/Description
-
Surgeons can compare three pre-graft methods for treating burn wounds. When using the split-thickness skin graft procedure, many different wound bed covers can be used. The lack of available donor sites can delay skin grafting. During this time, priming the wound bed is the best chance a patient has for full healing. An excised wound bed, an artificial dermal template, and a granulation tissue induced by cellulose sponge are all methods to prepare the wound for a split-thickness skin graft....

The lack of available donor sites can delay skin grafting. During this time, priming the wound bed is the best chance a patient has for full healing. An excised wound bed, an artificial dermal template, and a granulation tissue induced by cellulose sponge are all methods to prepare the wound for a split-thickness skin graft. All three wound bed covers are easy to apply and can be placed on bones and deep wounds, often without pain. Achieving reduced scar formation begins with a well-primed wound bed that can significantly improve the outcome of skin replacement.

Show moreThrough a series of workshops and incentives faculty will learn the benefits of adopting open educational resources (OER) in their classroom in place of costly publisher provided textbooks. Participants will commit to adopting OER in their course for at least three semesters. Indian River State College librarians know the value of OER having only taught credit courses using OER materials. Furthermore, librarians specialize in collecting, storing, describing, and evaluating information. Knowledge of OER and access to over one million library licensed scholarly materials makes a librarian the best person to implement college-wide, innovative OER adoption. This application was successful in receiving the Gladys Williams Wolf Endowed Teaching Chair in Communications on Monday, April 4, 2016.

- Advancements in dental pulp stem cells for potential therapeutic applications.
- Abstract/Description
-
Dental pulp stem cell research has provided new understanding regarding the subtle differences from the more commonly studied mesenchymal stem cells. The ability to differentiate into various types of cells, the ease of extraction, and ability to maintain clonogenic properties in cell cultures have led dental pulp stem cells to be an attractive alternative focus in stem cell therapeutic research. The recent research advancements that have led an endeavor for application in medicine and...

- Accuracy of 3D printed Models vs Traditional Stone Models.
- Abstract/Description
-
3D models are an essential device used in various fields of dentistry. Dental models are used for the fabrication of crowns, dentures, orthodontic treatments, and surgical equipment. Traditionally, 3D models are created from gypsum stone. However, 3D printed resin may provide a higher degree of precision and ease of sharing between professionals. Multiple studies have confirmed the accuracy of the Trios 3Shape 3D scanner, but few studies provide information on the reliability of 3D printers....
Show more3D models are an essential device used in various fields of dentistry. Dental models are used for the fabrication of crowns, dentures, orthodontic treatments, and surgical equipment. Traditionally, 3D models are created from gypsum stone. However, 3D printed resin may provide a higher degree of precision and ease of sharing between professionals. Multiple studies have confirmed the accuracy of the Trios 3Shape 3D scanner, but few studies provide information on the reliability of 3D printers. The purpose of this study is to determine the dimensional accuracy of 3D printed models for future application in dental and orthodontic treatments. Four anonymous participants received an alginate impression and 3D dental scans on the upper and lower dental arches for a resulting sample size of n=4. Prints were made from a Form Labs Form 2 3D printer and an Anycubic Photon 3D printer. These prints, as well as the gypsum model resulting from the alginate impression, were designated specific dental markers in which measurements were taken. Graphs of width and height were constructed after data analysis on Excel. There were no statistically different measurements between models of the same patient. Expected statistical differences were seen between patients, due to being different samples, which helped to validate the width and height measurements as statistically sound. This indicates that the measurements taken from stone models are as accurate as the 3D printed models. 3D printed models would be beneficial for cost reduction for orthodontic treatment and provide immediate surgical guides or dental study models.

The study investigated whether performance in any or all of the four instructional methods was moderated by age or language. Seventy three respondents participated in the study. Participants were enrolled in one of five sections of College Reading Preparatory II (REA0002) offered in the Spring of 2009 at Indian River State College in Fort Pierce, Florida. All five sections of REA0002 were taught by the same professor, a tenured faculty member, chair of the developmental reading department and Associate Professor of Developmental Reading at Indian River State College. The instruction and tests in all five sections of REA0002 were consistent with the research design which insured continuity and consistency in the use of the four instructional methods. All participants received the same treatment and quizzes. During the course of the study, participants first received a pretest, then the treatment or instruction, followed by an instructional quiz, and a delayed post-test was administered at the end of the study. An analysis of the data, which included the pretest, instructional quizzes withfour quizzes independently and then combined for an aggregate score for an immediate post-test, and the delayed post-test, yielded mixed results. The four instructional quizzes independently showed definition instruction to have the highest positive impact on student learning. In a measure of gains from pretest to instructional quizzes immediately after treatment, significant improvement in student learning was found only with word parts instruction. In a measure of performance from pretest to immediate post-test (aggregate score of instructional quizzes) there was a significant gain in students’ vocabulary competence, and from pretest to delayed post-test there was a significant decrement in students’ vocabulary competence. Age and language moderated vocabulary competence. Further tests of equivalency were mixed and should be interpreted cautiously, as there were a very small number of students in the group of 25 years or older and non-native English speakers.
