Yakonska, Viktoriya, STEM Undergraduate Research Symposium
- Abstract / Description

While various prosthetic hand designs are now widely available for the public to access and 3D print, there are few that offer the functionality of a traditional split hook design. For this reason, a design of a freely available split hook prosthesis is generated to be manufactured using a Fused Deposition Modeling (FDM) 3D printing process. This process is the most common and cost-effective form of 3D printing. Having the option to utilize a hook type prosthetic will allow the user to grasp...
Show moreWhile various prosthetic hand designs are now widely available for the public to access and 3D print, there are few that offer the functionality of a traditional split hook design. For this reason, a design of a freely available split hook prosthesis is generated to be manufactured using a Fused Deposition Modeling (FDM) 3D printing process. This process is the most common and cost-effective form of 3D printing. Having the option to utilize a hook type prosthetic will allow the user to grasp objects ranging in sizing. This task is difficult with a prosthetic hand which is designed for the intention of resembling an anatomical hand such as ones offered on the e-NABLE database. Many individuals are financially challenged and are incapable of affording traditional split hook prosthesis, while others do not have access to traditional prosthetic care. This design tries to overcome these challenges. The design provides an easily manufactured, parametric prosthesis that maintains affordability, and availability for all. The design is equally beneficial to users who already own a traditional prosthetic device. With the option of 3D printing the split hook design, the user benefits by owning a secondary prosthesis for environments aversive to the traditional more expensive device.

Water quality problems can arise from excess nutrients and other chemicals. The problematic chemicals may be from septic tanks, surface applications on lawns and agricultural fields, or insufficient waste water treatment practices. The community of San Carlos Park, Lee County Florida provides a good model to examine potential sources and fates of these chemicals.

Show moreWater quality problems can arise from excess nutrients and other chemicals. The problematic chemicals may be from septic tanks, surface applications on lawns and agricultural fields, or insufficient waste water treatment practices. The community of San Carlos Park, Lee County Florida provides a good model to examine potential sources and fates of these chemicals. The community has over 6000 residences, over 90% of which are using septic tanks for wastewater treatment. We are examining whether there is a measurable presence of chemical of emerging concern (as an indicator of presence of human impact), in addition to water quality parameters, in the surface waters along the East Mulloch Drainage District. Nutrients were analyzed at Lee County Hyacinth Control Lab using an automatic analyzer (AQ2 by Seal Analytical) and chemicals including sucralose were analyzed at FIU Southeast Environmental Center using solid phase extraction liquid chromatography. Atrazine, simazine, propazine, and cyanazine were analyzed at FGCU. A comparative analysis was conducted using the results of the samples collected in March 2017 and September 2017, which allowed us to see if there were problematic chemicals in the surface waters of the East Mulloch Drainage District, in San Carlos Park Florida. Our results indicate that sucralose was found in all seven samples we took in March of 2017. Our results also showed that there were significant differences in ammonia, total nitrogen, and nitrate/nitrite levels between March 2017 and September 2017. However, there were no levels of any nutrient that were above the EPA’s acceptable contaminant levels, and the differences observed can be attributed to seasonality.

Markovich, Alyson, Research Day
- Abstract / Description
-
In the acute care setting, patients are sent home from the hospital and are subsequently returning to seek out care, within 30 days. This occurance has created a national quality goal of reducing readmissions. (Rice, Hillstrom, Barnes, Rastogi & Steinkeler, 2016). The protocols in place for efficiency set by the hospital in regard to the instructions given to the patients as they are leaving the facility are one of the issues in patients returning to the hospital (Ashbrook, Mourad & Sehgal,...
Show moreIn the acute care setting, patients are sent home from the hospital and are subsequently returning to seek out care, within 30 days. This occurance has created a national quality goal of reducing readmissions. (Rice, Hillstrom, Barnes, Rastogi & Steinkeler, 2016). The protocols in place for efficiency set by the hospital in regard to the instructions given to the patients as they are leaving the facility are one of the issues in patients returning to the hospital (Ashbrook, Mourad & Sehgal, 2012). These non-specific protocols prove that it is not only imperative to assess the patients feelings and understanding of their disease process, but also their management of care. This could be addressed by nurses empowering the patients about their disease (Akpotor & Johnson, 2018). This evidence-based research will address the nurses and their impact on improving the confidence of patients regarding their disease process and management, in addition to improving the administration of disease management instructions (Ackermann et al., 2016). When addressing this multi-focal issue in the health care system, this research identified vulnerable areas of practice including the ability of nurses to adequately teach patients what they need in order to go home safely. This study should yield information and results that could reduce the rate at which patients are returning to the hospital. A qualitative, evidenced-based literature review supports the evaluation of improving nurses teaching abilities. In order to change the outlook and application of the education given when the patient is returning home, the nurses will be randomly selected on the pilot Designated Education Unit of the Gulf Coast Medical Center. Although the scope of practice for a nurse is hardly defined, one universal truth remains that the art of nursing includes the aspect of caring. Change cannot happen without showing nurses that they can be confident and inspired when caring for their patients. Addressing the problem with nurse empowerment is the beginning of tackling one of healthcare’s most significant reoccurring problems.

We propose to find another proof that π is irrational. Thus far, there are two major arguments. The first--originally due to Lambert--uses the continued fraction representation of the tangent function and some other properties of that very function. As such, Lambert's proof (done rigorously) requires deep results from algebra and analysis. The second is originally due to Hermite and uses elementary calculus. Hence, Hermite's proof can theoretically be understood by students with little...

Ciguatoxin is believed to be a toxin that bioaccumulates and biomagnifies from lower trophic level grazers, however, food web interactions from these organisms are relatively unknown. Small scale grazing experiments can be conducted using agar plating of Gambierdiscus cells with the addition of herbivorous grazers, such as copepods, snails, or small crustaceans. There have been few studies agar plating techniques with Gambierdiscus leaving a gap in knowledge. In this experiment, two Gambierdiscus species are to be used, G. caribeaus and G. silvae, in agar plating techniques to determine the most productive technique.

Archaeologists have questioned whether scallop beds associated with Calusa Native American middens were a product of harvesting for food. A scallop assemblage was recovered from a bed within a Late Archaic (785-745 BC) Calusa midden located on the northern end of Pine Island, Southwest Florida. Two hypotheses were tested: (1) the scallops in the collection represent one population of Argopecten irradians (Atlantic Bay Scallop, ABS), and (2) the scallops were harvested by the Calusa.

Show moreArchaeologists have questioned whether scallop beds associated with Calusa Native American middens were a product of harvesting for food. A scallop assemblage was recovered from a bed within a Late Archaic (785-745 BC) Calusa midden located on the northern end of Pine Island, Southwest Florida. Two hypotheses were tested: (1) the scallops in the collection represent one population of Argopecten irradians (Atlantic Bay Scallop, ABS), and (2) the scallops were harvested by the Calusa. Evidence to support species identification comes from rib count, shell length, and ctenolium teeth. Specimens were consistent with the morphology of ABS, rather than the A. gibbus (Calico Scallop) (Mikkelson, 2008). Ribs number between 17-22, lengths range from 4.1-7.3 cm, and the ctenolium have 3-5 teeth. Nearly half the shells displayed systematic breakage along the ventral edge, suggesting the scallops were harvested. The pristine taphonomic grades of the shell interiors, versus the poorly preserved shell exteriors, support the notion that scallops were removed from the estuarine environment alive, killed, and then deposited on land as refuse, as opposed to being deposited by natural forces. Scallops were clearly harvested as food by the Calusa. Whether the fishery was over exploited has yet to be determined.

Show moreThis research is a review of 5 edible plant species grown in subtropical regions around the world. Each of the following species is agriculturally important in subtropical regions, especially in areas of low affluence: Moringa oleifera, Ipomoea batatas, Manihot esculenta, Cajanus cajan, and Cnidoscolus aconitifolius. These five-plant species, often considered to be “miracle crops” are well-known for having health benefits in the climates in which they thrive. However, there is no information regarding which species is best suited for any given situation. In this study, the primary literature was surveyed for information on the economic value, nutritional value, medicinal value, other ethnobotanical values, productivity, as well as temperature, nutrient and pesticide requirements. Originally, a meta-analysis was planned for these species, however there was not sufficient data for such an analysis. Instead, each species was ranked according to the 8 traits/values listed above to determine which species are best suited for particular situations. I concluded that having a thorough evaluation on these 5 perennial plants will help farmers and backyard gardeners throughout the world know which plant species is most productive in each area based on a series of given information

Show moreChemicals including medications, personal care products (PCPs) pesticides and plasticizers can disrupt the endocrine system. Physiological and morphological changes in mosquitofish Gambusia upon exposure to endocrine-disrupting chemicals can be easily detected since their anal fins are sexually dimorphic. Male anal fins are specialized to deliver sperm to the live-bearing female mosquitofish. We hypothesized that there may be evidence of endocrine disruption in fish collected from surface water in San Carlos Park, Fl because that community relies primarily on septic tanks, and residents have lawns that may be using pesticides. According to the literature, the ratio of the 4th to 6th anal fin rays in females is 1:1. The 4:6 anal fin ratios of female fish was actually found to have an average of 1.3 with all 13 sites being greater than 1.2. The females we examined are being masculinized, which is an indication of an androgenic endocrine disruptor being present. This is of great importance as Gambusia are a model for live-bearing organisms therefore is able to be generalized to a greater population, one that could potentially include humans.

Baerson, Joanna, Arvay, Kaylee, Schuller, Kelly, Research Day, Jansen, Kaylee
- Abstract / Description
-
Health and longevity are strongly positively correlated. Self-rated health (SRH), or perceived health, is a good predictor of mortality in older adults. Although college students typically rate themselves as overall healthy, measures of self-rated health have been correlated with physical health, academic performance, and mental illness, such as depression. This study aims to examine the relationship between self-rated health and projected age of death in a college aged sample.

Oysters collected from the restoration and reference sites were shucked, dried, and ground into a powder for analysis of copper concentration using an X-Ray Fluorescence Spectrometer. In addition, stringers with oyster shells were placed at the sites and were checked monthly for spat (baby oyster) recruitment. Oyster reefs perform important ecosystem functions, as a biogenic structure that provides nursery habitat to young fish and crustaceans, and as a filter feeder that can keep particulates and suspended sediments out of the water column. Copper enters Naples Bay through freshwater runoff via the Golden Gate Canal system, a watershed where copper sulfate is applied as an algaecide to canals, ponds, and golf course hazards. This study aimed to better understand how copper affects oysters and spat recruitment in Naples Bay.

Coliform bacteria which were resistant to high concentrations of a number of antibiotics were isolated from the water samples, including possible E. coli colonies. Bacterial isolates were screened for the presence of class one integrons using PCR for the intI1 gene. Class one integrons can encode genes for antibiotic resistance and their presence is associated with poor waste management. All bacterial isolates tester were negative for the presence of the intI1 gene.

With overuse of antibiotics and poor waste management, aquatic environments have become a breeding ground for antibiotic resistant bacteria containing these integrons. It’s important to track integron activity to help prevent worldwide bacterial resistance. Water samples were taken in the Fort Myers area in triplicates from Dogs Beach, Fort Myers beach, FGCU waterfront, Yacht club, Barefoot Beach and 41 bridge. Descriptions of the area such as animals, people, vegetation and weather were observed at each location. Coliform bacteria were selected from the water samples using EMB agar and antibiotic resistance bacteria were isolated using various degrees of antibiotic agar. Bacterial isolates were sequenced via PCR, identified by agarose gel and compared to intl1 gene from a class one integron. Class one integrons confers antibiotic resistance and their presence is associated with poor waste management. The sample from Fort Myers beach had antibiotic resistant bacteria and the EMB had small traces of E. coli, but all bacterial isolates were negative for the present of the intl1 gene from the class one integron.

Show moreA difficult intubation poses one of the most challenging tasks for anesthesia professionals, representing 27% of all adverse respiratory events, 93% of which are unanticipated. Unanticipated difficult mask ventilation and intubation may result in serious complications. Safe airway management requires a proper and thorough preoperative airway evaluation and a plan to secure the airway, with alternate plans available when the initial plan fails. Pediatric, obese, and obstetric patients undergoing general anesthesia with endotracheal intubation are considered to be at risk of rapid desaturation. As an adjunct to conventional preoxygenation techniques, continuous oxygen administration during the apneic period, termed apneic oxygenation, assists in the maintenance of oxygenation when tracheal intubation is attempted. Nine articles were selected for appraisal in this literature review: 6 randomized control trials, 2 prospective studies, and 1 retrospective study. Multiple apneic oxygenation techniques, including nasopharyngeal catheter, nasal prongs, endotracheal tube, intratracheal catheter, and high-flow transnasal humidified oxygen, demonstrated effectiveness at delaying the onset of hypoxemia during the apnea period. Prolonging the apneic window changes the nature of airway management in patients at high risk of desaturation and when an unanticipated difficult airway arises.

Show moreFlorida Red tide is a natural phenomenon, having been recorded by Spanish explorers as early as the 15th century. However, nutrient inputs from anthropogenic sources in recent years has exacerbated the issue. The dinoflagellate (K. brevis) is responsible for the release of neurotoxins known as brevetoxins. Brevetoxins are sources of respiratory irritation when aerosolized, as well as neurotoxin shellfish poisoning once accumulated in shellfish and ingested. Brevetoxins sorbed to sedimentary particles, which is followed by sinking and burial into the seafloor sediments. These toxins can be persistent in sediments, resulting in their accumulation in sediment and marine organisms. The accumulation rates of brevetoxin in Southwest Florida (SWF) coastal sediments reflects past red tide events, recent urbanization and population growth in this region. The main objective of this study was to determine vertical profiles of brevetoxins accumulated and preserved in SWF coastal-marine sediments.

Show moreSince 1982, stormwater ponds are mandated in Florida to remove more than 80% of the pollutants from the runoff loading into them as well as mimic, through flow regulation, the natural hydro-patterns. However, such ponds are often mismanaged because of questionable aesthetic practices which render them more eutrophic. Most sponsored water quality studies conducted on SW Florida ponds have been conducted on 1.5% of the ponds of Lee and Collier counties. It is unsure whether such studies reflect the real inclusive water quality of all the other ponds since, generally, ponds are studied because of their visual dystrophic state. Thus, this study uses visible aerial Google Earth Pro pictures and utilizes the red, green and blue (RGB) composition of the pictures of the limnetic zone of the ponds to determine their degree of eutrophication. Only 1401 residential ponds out of 4220 (33%) were studied. The RGB measurement was conducted using the software GNU Image Manipulation Program GIMP2. A review of the algorithms used to determine the chlorophyll concentration using RGB pictures was subsequently performed and an algorithm was then selected to be used for our data. A simple linear relationship was then used to convert the algorithm results into chlorophyll a concentrations which were subsequently transformed into Trophic Status Indexes using the proper formula developed for Florida lakes. A histogram was then generated and showed that the vast majority of Collier pond seemed nutrients rich.

Even though not all of the piezometers have been installed, the data base generated by Johnson Engineering which encompassed the 1997-2012 period with up to 27 piezometers was used to compare spatiotemporally the water table elevation across campus. Results show that there is a seasonal fluctuation of the groundwater table with a low elevation during the dry season which contrasts with a high elevation during the wet season. When the seasonality was removed, and the data plotted for a given month over years, odd years of El-Niño and La-Niña were not consistently showing higher water tables elevations and lower water tables elevations respectfully. In September and October, the water table has the same elevation regardless of extraordinary seasonal fluctuations. Finally, the mapping of the average groundwater table elevation over years across campus for the months of September and March showed that water moved swiftly following a NE-SW pattern whilst in March, water moved much less but still kept that same aforementioned direction. Even though the percentage of impervious surfaces increased over time on campus from 0 in 1995 to 13.6% in 2004-2008 and up to 18.3% in 2017, the maps did not suggest that such surfaces altered the groundwater table. However, with more data extracted from the Johnson Engineering database and with 47 additional wells and pond water levels, this assertion might change.
