Facilitating Biodigester Biogas Production Using a Rumination Model of Bos taurus

Abstract In order to develop resource and time efficient methods of biogas production as an energy source, the biodigestion procedure physically and chemically modified the biodigestion process to mimic the rumination process of Bos taurus. The experimental protocol used manure slurry and the independent variables of a varying mixing times and digestive enzymes to produce biogases. The results demonstrated significant increases in biogas production with both mixing time variation and enzyme additives to manure slurry. […]

Policies to Protect Diminishing Bee Populations in the United States

Honey bees are pollinators that have a strong influence on ecological relationships, ecosystem conservation and genetic variation in plants, with pollination occurring in a variety of ways: wind, animals, self-pollination and sexual reproduction. According to Greenpeace, an estimated 87.5% of flowering plants are pollinated by animals, and can increase fruit or seed in 75% of the world’s food crops ((Greenpeace Research Laboratories Technical Report (Review) 01/2013)). Greenpeace also shows that although grains such as wheat, […]

Technology Inspired by Nature: A New Method to Preserve and Protect the Earth

Technology Inspired by Nature: A New Method to Preserve and Protect the Earth by Jueun Yi Orange County School of the Arts   There it was: a used glass pane from a window, 110 pieces of solar cells, and solders. My mission this summer was to build a 43.25” by 73.75” solar panel for Mr. Danielson. The basic instruction appeared simple enough since my two main tasks for this project was to solder and to […]
