Effects Of Red Light Intensity On Cultivation & Oxygen Production In Arthrospira Plantensis, Abigail Roberts Dec 2022

Effects Of Red Light Intensity On Cultivation & Oxygen Production In Arthrospira Plantensis, Abigail Roberts

Honors Theses

Maintaining life sustaining resources during long-term space travel has encouraged scientists to turn their attention to the potential benefits of a cyanobacteria named Arthrospira platensis, commonly known as Spirulina algae. This experiment measures the oxygen production and cell population growth of two structurally different Spirulina cultures under two different levels of red light intensities, 8 µmol/m 2Js (high); 3 µmol/m2/s (low). The cell population, oxygen produced, and oxygen produced per cell measurements were observed and recorded at three 24 hour intervals. It was found there was not a significant difference between high and low light intensities when considering the cell …


Simultaneous Determination Of Bpa And Bps Using Uv/Vis Spectrophotometry And Hplc, Jean Eudes Benecyo Jan 2016

Simultaneous Determination Of Bpa And Bps Using Uv/Vis Spectrophotometry And Hplc, Jean Eudes Benecyo

Honors Theses

Bisphenol A (BPA) has been one of the most used plasticizers with more than 4.8 million tons produced in 2012. BPA is also an endocrine disruptor that has been linked to adverse health effects such as cancer, obesity, behavioral and mood changes, lowered fertility, developmental changes and more in humans and other animals. The evidence of the toxicity of BPA, even at very low levels, has caused many countries to limit its use, especially in baby bottles and other baby-related hard plastic items. In these times, BPA has been replaced with other bisphenols, such as Bisphenol S (BPS). BPS is …


Bringing Bpa To Light: Determination Of Bisphenol A In Thermal Receipt Paper Water Samples And Lake Water Samples Using Fluorescence Spectrophotometry, Bailey Chitwood Jan 2015

Bringing Bpa To Light: Determination Of Bisphenol A In Thermal Receipt Paper Water Samples And Lake Water Samples Using Fluorescence Spectrophotometry, Bailey Chitwood

Honors Theses

Bisphenol A (BPA) is a chemical that is commonly used in harder plastic products, in the lining of food cans, and in thermal receipt paper. The usage of BPA in common products has become a concern for humans, especially for infants and young children, because of its effects as an endocrine disrupter. BPA has been linked to diabetes, cardiovascular disease, obesity, and certain developmental disorders. Because of the possible effects of BPA on the development of infants and young children, the use of BPA in baby bottles and other baby products has been outlawed. However, BPA is still used in …


A New Me: A Study In Diet Therapy, Marsha Ellis Jan 1973

A New Me: A Study In Diet Therapy, Marsha Ellis

Honors Theses

Obesity is a major problem in our nation today. It Seems that we are eating too much and exercising too little. We can analyze, discuss, and write about obesity from now through eternity. However all of this is in vain, unless it causes us to lose weight.
