The Effects Of Light Intensity And Cell Structure On The Cultivation Of Arthrospira Platensis, Taylor Barnhart
The Effects Of Light Intensity And Cell Structure On The Cultivation Of Arthrospira Platensis, Taylor Barnhart
Honors Theses
As scientists explore further into space, more cost-effective resources are needed for long-term space travel. An interesting solution is Arthrospira platensis, a filamentous cyanobacteria high in proteins and nutrients, and known for its helical structure. In unfavorable conditions, coiled spirulina cells become straight. Spirulina converts carbon dioxide gas into pure oxygen and the different cell structures stimulate different responses in oxygen production and cultivation. In these experiments, 2.3 L containers of pure coiled spirulina and mixed (coiled and straight) spirulina were placed into 3 incubators with different light intensities: 51μmol/m2/s, 25μmol/m2/s, 12μmol/m2/s. Each experiment length was 72 hours and the …

A Brief Summary Of Insects's Vision And Their Response To Light, Tim Matthews
Honors Theses
Insects have been studied and observed since man first walked this earth. Man's first observation was that some insects were quite palatable. One of Christ's contemporary's, John the Baptist, maintained a diet which consisted of "honey and locusts". The spittings of another insect provided nourishment for the Children of Israel during the Exodus. Even today insects are of primary importance in the ecology. It is only a small minority of the insect population that are nuisances. The vast majority of the insect population is not only beneficial to man but also to the rest of the animal kingdom and to …
