The Biodegradability of Corn Produced Plastic

Plastic is the product most commonly disposed of inappropriately. Not only does plastic take centuries to disintegrate into the earth, but it secretes toxic chemicals in the process. The pur…

The Biodegradation of Styrofoam through the Use of Superworm Gastrointestinal Flora

Styrofoam poses a huge global threat due to its toxicity. Unfortunately, it is accumulating in the environment because it takes thousands of years to decompose. The purpose of this experimen…

The Birthday Paradox: An Application to the USA's No-Fly List

Data coincidences are an important aspect of our digital age. An example of this is the US No Fly List. Over 90,000 names are on the No Fly List. Given that more than 8 million people fly ea…

The Brachiaria humidicola in the Soils of Puerto Rico and Its Contribution to the Environment

The purpose of this investigation is to demonstrate that Brachiaria humidicola, a pasture that grows in cattle farms, provides great benefits both to the environment and agriculture. The pro…

The Braille Sleeve

It is known that people with sensory disabilities suffer from vision and hearing impairment. That is why I have worked out a device that helps the disabled be able to communicate with people…

The calculation of surface area and volume of k-balls inscribed in a regular prism and pyramid.

The purpose of this project was to find relation between the volume of a prism and a truncated pyramid with regular n-sided polygon base and to show that the surface area and volume of the k…

The Cancer Breathalyzer, Part II: Chemical Strips that Detect Chemicals in Breast, Colorectal, and Prostate Cancer Breathprint

Energy: Sustainable Materials and Design
