How Akron Affects The Water Quality Of The Cuyahoga River, Allyson Darst Jan 2023

How Akron Affects The Water Quality Of The Cuyahoga River, Allyson Darst

Williams Honors College, Honors Research Projects

The purpose of this study was to analyze whether the city of Akron had negative effects on the Cuyahoga river, and determine if the Cuyahoga River was naturally able to remediate these effects downstream. The pollutants measured in this study include hardness, bromine, residual chlorine, iron, copper, lead, nitrate, nitrite, ammonium chloride, total chlorine, fluoride, carbonate, pH, total alkalinity and cyanuric acid. This study was done using water testing strips (JNW Direct) to test the water at four different locations along the Cuyahoga River downstream (North) of Akron. This study found that the city of Akron does have a negative …


Varying Water Stress In Mimulus Ringens, Sara Stiles Jan 2018

Varying Water Stress In Mimulus Ringens, Sara Stiles

Williams Honors College, Honors Research Projects

A wetland plant’s ability to tolerate flooding is important to determining where that plant can grow. Previous studies have shown the optimal flood tolerance of Mimulus ringens is between -2cm and -6cm (Fraser & Karnezis, 2005). This experiment expands on these previous experiments by testing variation in water levels instead of maintaining the water levels at one height throughout the experiment. The hypothesis of the experiment is that Mimulus ringens that have variation in water levels will show signs of better growth than plants with a constant water level. Contrary to predictions, the results showed the final height, number of …


Application Of Lipid Styryl Dye For Staining Intracytoplasmic Membranes In Gram-Negative Bacteria, Theodore J. Hammer Jan 2015

Application Of Lipid Styryl Dye For Staining Intracytoplasmic Membranes In Gram-Negative Bacteria, Theodore J. Hammer

Williams Honors College, Honors Research Projects

Intracytoplasmic membranes are structures that form within cells which help facilitate a variety of different metabolic processes. This feature of intracellular membranes makes them particularly valuable for studying compartmentalization and cell dynamics in bacteria. In the past, transmission electron microscopy has been the primary method for imaging bacteria with intracytoplasmic membranes. Because transmission electron microscopy takes images of a cell in fixed slices, it’s impossible to follow a cell’s growth and development over time. Fluorescence microscopy is a particularly effective method of measurement that can combat these issues when evaluating live bacterial cells. Here, standard biochemical laboratory procedures were used …
