Mechanisims of Vortex Oscillation in a Fluidic Flow Meter

By: Mohammed Al-Muqbel and Peshala Gamage | Mentor: Dr. Hansen Mansy

Flow meters are devices capable of measuring the amount of fluid transported through piping networks. Example applications include accurate measurements of flow in chemical processing plants and fluid consumption by end-users (e.g. water, fuel, natural gas, etc.) by customers, which is a core issue in fluid-handling engineering. Some flow meters contain no moving parts (Royle and Boucher 1972), which is desirable since moving parts wear over time, leading to compromised meter accuracy. Read more

Temperature Effects on Greenhouse Gas Production From Treatment Wetland Soils Along a Nutrient Gradient

By: Kyle Dittmer and Havalend Steinmulle | Mentor: Dr. Lisa Chambers

It is generally accepted that increased temperatures are positively correlated with microbial respiration rates, causing greater greenhouse gas (GHG) emissions (CO2 and CH4) from wetlands. The goal of this study was to understand the potential for interacting effects of temperature and nutrient concentrations on GHG emissions from wetland soils. Complementary field studies and a laboratory study were completed within Cell 1 of the Orlando Wetlands Park (Christmas, FL). Read more

The Brothers: A Study of the Social Structure Between Two Captive Cheetahs

By: Cheniene Clemens | Mentor: Frank Logiudice

Cheetahs (Acinonyx jubatus) are easily differentiated among other species of Felids. They exhibit unique physiological features, as well as displaying a social structure that has not been observed with other species of Felid. Coalitions of male cheetahs are seen both in the wild and in captivity, while female cheetahs remain solitary. This paper is a compilation of a twelve-week observational study of the two male cheetahs at the Central Florida Zoo in Sanford, Florida. Read more

Earthseed Planted: Ecofeminist Teachings in Octavia Butler's Parable of the Sower

By: Delia Shahnavaz | Mentor: Farrah Cato

Earthseed Planted: Ecofeminist Teachings in Octavia Butlers Octavia Butler's Parable of the Sower is set in a world where patriarchal supremacy has stifled not only womankind, but also the natural environment of the Earth. By exploring the innate connection between the desecrated Earth and the strangled matriarchy, this paper draws direct links to Butler's world and ecofeminist theory by Vandana Shiva and others, ultimately concluding that Butler's "Earthseed" serves as a representation of a world in which ecofeminism reigns supreme.

Microgravity Experiments on Accretion in the Protoplanetary Disk

By: Addison Brown and Stephanie Jarmak | Mentor: Dr. Joshua Colwell

Microgravity Experiments on Accretion in the Protoplanetary Disk We present the results of an experimental investigation of low-energy collisions between cm-scale and smaller particles in the protoplanetary disk to better understand conditions conducive to the growth of planetesimals, the km-sized building blocks of planets. The COLLIDE (Collisions Into Dust Experiment) and PRIME (Physics of Regolith Impacts in Microgravity Experiment) programs involve cm-scale projectiles impacting a target bed of unconsolidated granular material in microgravity environments on Space Shuttle missions and parabolic airplane flights, respectively.
