  1. Sustainable Energy on JCCC Campus - Implementation and LimitationsFri, 27 Apr 2018 13:30:00 PDT
    This project is intended to find what has helped JCCC to attain its goals in energy sustainability, what some of the obstacles have been / will be in that pursuit, and how we can overcome them. This will be used as a model to be applied to community colleges in general. In doing so the effectiveness of certain sustainable implementations will be researched. I.E. solar ; LED implementation on campus, and more efficient appliances being installed on campus (blower motors for HVAC system). More...
  2. Using Power Harvesting Techniques to Improve Medical Device ReliabilityFri, 27 Apr 2018 13:30:00 PDT
    Hearing aids are devices used to cope with the effects of hearing loss, usually sensorineural hearing loss. This type of hearing loss makes sounds muffled and it can make it harder to understand different sounds especially in noisy environments. There is 48.1 million people in the US with mild or greater than mild hearing loss. But surprisingly, only 24 percent of people with hearing loss have hearing aids. Hearing aids are inconvenient because of their dependence on batteries, there is a social stigma revolving around them, and a quality hearing aid can cost up to five thousand dollars. These are problems with the hearing aid that I set out to solve in my project. I developed marketing techniques through interactions with Rob Neville, CEO of Savara Pharmaceuticals, as well worked with Dr. Paul Thibado from the University of Arkansas through email to develop energy harvesting circuits. My main interests in his research have to do with the fluctuations of freestanding graphene for the use of clean, limitless, renewable energy to power small devices. I am now making arrangements to work with him during the summer. More...
  3. Suggestive Selling and its Impact on SalesFri, 27 Apr 2018 13:30:00 PDT
    For my first foray into independent study and scientific research, I set out to see whether or not suggestive selling positively impacted sales, as most employers claim. I studied previous research in the field, and then tested the techniques in the stores I work in. Using sales printouts from the test period and the prior year's sales, I used statistical analysis and hypothesis tests to determine if my experimental results were indicative of positive change in merchandise sales and if they coincided with the standing research. Although my personal data did not show a significant difference in merchandise sales, I have been able to designate key areas I can coach my coworkers in to improve their suggestive selling techniques, which may result in a statistically relevant increase in the long term.

  4. The Process of Rendering FractalsFri, 27 Apr 2018 13:30:00 PDT
    Fractals and other figures on the complex number plane plane are beautiful, elaborate, and have interesting unique properties. However, fractals such as the Mandelbrot set are difficult to render efficiently at high resolutions. This poster will cover the process of creating a program in Python to render the Mandelbrot set and other fractals at various resolutions for the purpose of creating an animation. More...

  6. Measuring the Earths CircumferenceFri, 27 Apr 2018 13:30:00 PDT
    For my honors contract in the field of Astronomy, I decided to replicate the Greek scholar Eratosthenes, in his observations and experiment that justify that the earth is spherical. The motivation behind this project is to disprove those who deny the value of science and empirical observations. More than 2000 years ago the Greek scholar Eratosthenes reached the conclusion that the earth was a sphere. He did this using the angle derived from the cast shadow length versus the objects height, taken in two cites a known distance apart, and on the same day. I gathered part of my data by utilized a live web cam at the Pier House 60 hotel in Clearwater, FL and took screen shots when the Sun was at its local zenith. Then using Auto Cad, I took measurements of various objects height and shadow lengths. Knowing these two lengths, even using the arbitrary plot system of Auto Cad, with simple trigonometry you can determine the angle of the sun at that time and location. In conjunction to the data collected from the web cam, I also took measurements at Galileos Pavilion during Suns local zenith the same day. Although the tools at my disposal are much more sophisticated than what Eratosthenes had access to, the application is the same. Accepting that rays of electromagnetic radiation incoming from the sun are parallel. The change in altitude angle of the Sun between two locations, is the angle of the arc distance between the two measurement points. More...
  7. Small World Initiative Antibiotic ResearchFri, 27 Apr 2018 13:30:00 PDT
    Throughout this experiment, we attempted to identify bacteria strains that exhibited antibiotic activity. To do this, we isolated soil bacteria from a soil sample. I chose my soil sample from an unadulterated, natural environment. I did not want a suburban sample influenced by chemicals and fertilizers. I hypothesized that a sample within a natural environment would have more microbial variance, and thus I chose to obtain a sample from a deciduous forest adjacent to a floodplain. We diluted the concentration of our strains with water. We allowed our strains to grow for a few days, and afterwards observed for zones of inhibition that represent a region where the bacteria cannot grow (thus showing antimicrobial activity). We then isolated these potential strains on a master plate. My sample contained 4 potential candidates. Then, we tested these promising samples of bacteria to observe their antimicrobial activity on ESKAPE pathogen relatives. Unfortunately, none of my candidates exhibited antibiotic activity towards the ESKAPE pathogen relatives. Thus, I made a streak plate using a classmates strain. When isolated, I will use staining methods (form of metabolic testing) to determine its cell wall composition. The cell wall composition is an important indicator of what species of bacteria is present. Once the type is identified, we will identify its genetic identity using using PCR analysis via gel electrophoresis and discover its phylogeny (family tree) via an online database with genomic information.

  8. Analysis of a Soil Sample for Antibiotic PropertiesFri, 27 Apr 2018 13:30:00 PDT
    I retrieved my soil from Heritage Park by the playground. I picked this soil because it would potentially have bacteria children commonly carry on them. To find antibiotics in this soil I first put the soil through the dilution process. This made bacteria grow on the agar plates. As I diluted the soil and grew bacteria I watched for zones of inhibition. This is when bacteria secretes an antibiotic to keep other bacteria from touching the colony. When I found twenty different types of bacteria that had an inhibition zone I made a master plate of all of them. Next, I tested for antibiotics by using the Eskape relatives. I tested all the of the Eskape relatives by making a straight line down the middle of the agar plate and adding bacteria to the sides of it to where they touch. If they dont touch after the bacteria has had a day to grow, then the bacteria are producing an antibiotic. None of the bacteria I grew from my playground soil produced an antibiotic. Although I do find it interesting most of the bacteria I grew were cloudy and yellow or orange and sticky. I dont think I picked a good soil sample because the bacteria werent as diverse as I thought. More...
  9. Newly discovered pathogen, Bananateria181, possible inhibitor of Escherichia coliFri, 27 Apr 2018 13:30:00 PDT
    The ESKAPE PATHOGEN research project helps students like me find potential candidates that inhibit the pathogens that are continuing to grow more resistant to the antibiotics we use everyday. The process of serial diluting the soil found from different areas, plating the dilutions on 50% TSA media, and autoclaving the plates, we are able to then try and find potential candidates that inhibit the safe relatives. A potential candidate on the 10-1 plate was further tested using the cavalier method and was found it inhibited the Escherichia coli virus and a streak plate was made. Finding a new antibiotic for this pathogen would mean we can save more lives and help patients with the illness recover faster. The soil sample from this experiment was taken from the hill in the middle of the JCCC campus on the second step. Continuing this research, means hoping to learn more about the E coli virus and to potentially find new ways to create antibiotics that resist this pathogen. More...
  10. Antibiotic ResistenceFri, 27 Apr 2018 13:30:00 PDT
    Antibiotic resistance is no longer a fear for the future, but rather a problem for the present. We are starting to see more and more infections become resilient to the antibiotics that once offered a cure. In order to find new medications to treat common infections, weve partnered with Small World Initiative, which is a student research program that is advancing the search for new antibiotics around the globe. The process begins by collecting a sample of dirt, and diluting it down so that only microscopic organisms are left. Those organisms are then grown on an agar petri dish, and promising candidates are further tested against strains of pathogenic (infection causing) organisms. The goal of this research is to find an organism that inhibits anything from growing around it, this includes the various pathogenic strains. The microbe that I found to do this was collected from clay soil on 2/1/18, when the temperature was at 32 degrees Fahrenheit. After I completed all the steps through the small world initiative project I was able to find such a candidate that inhibited some pathogenic strains, but not others (such as Staphylococcus epidermidis). The Small World Initiative research program allowed me to explore and discover a new possible antibacterial microbe. The data presented follows from start to finish the entire process explained above. More...
