Cost Efficient Method Of Pumping Water For Small, Remote Rural Communities, James Hudson
Chemical Engineering Undergraduate Honors Theses
Many technologies are used for water disinfection. Chlorine, iodine, and ozone are some chemical methods of water disinfection. Filtration, including microfiltration, ultrafiltration, and reverse osmosis, is used to remove bacteria. In addition to chemical and filtration technologies, one can disinfect water using UV irradiation, ultrasonic treatment, electrolysis, solar disinfection, and slow sand filtration.
Currently, there are few solutions being employed in third world settings for communities. The current solutions are either for one household or are part of an existing infrastructure and therefore are not portable. Slow sand filtration is used successfully to provide potable water for individual households. Tablet …

Synthesis And Analysis Of The Antimicrobial Peptoid N-Lfb6, Allen Busick
Chemical Engineering Undergraduate Honors Theses
The increasing presence of drug resistant bacteria has led to research of new methods to combat bacteria. A part of the natural peptide Lactoferricin, LfB6 (RRWQWR-NH2), has been shown to be effective against a variety of gram positive and gram negative bacteria. However, there are several problems associated with peptides. Peptides can quickly degrade in the body which causes larger doses to be effective. Large doses of some peptides are cytotoxic to the host. Peptoids are a class of compounds that can potentially mimic the function of peptides and circumvent the problems associated with them. The backbone of peptoids is …

Non-Natural Protein Mimetics For The Treatment Of Alzheimer's Disease, Jennifer Herrera, Amanada Compean, Jasmine Brown, Melissa Moss, Shannon Servoss
Chemical Engineering Undergraduate Honors Theses
Alzheimer's disease (AD) is a slow degenerative disease that causes memory loss and eventually leads to death. AD is caused by the aggregation of the amyloid-beta protein, found on the outside of brain cells; once the amyloid-beta protein begins to aggregate it forms plaques on the extracellular part of the neural cells. To date there is no AD medication commercially available that breaks up the amyloid-beta aggregates. Current research has found that certain molecules bind to the amyloid-beta protein and prevent aggregation. The purpose of this research project is to engineer a peptoid-based molecule to stop the aggregation of the …

Understanding The Effects Of Hydrophobicity For The Detection Of Methylated Dna By Microchannel Electrophoresis, Micah Fritsche
Understanding The Effects Of Hydrophobicity For The Detection Of Methylated Dna By Microchannel Electrophoresis, Micah Fritsche
Chemical Engineering Undergraduate Honors Theses
DNA methylation is an epigenetic mechanism used for long - term silencing of gene expression. This silencing of gene expression can be involved in the down regulation of genes involved in apoptosis, which is a process of regulated cell death, and this inability to break down cells can ultimately lead to tumor formation in cancer. Methylation of DNA follows a certain pattern through developmental stages of an individual, and this pattern is normally maintained throughout that individual's life. However, in the DNA of older individuals, this methylation is commonly seen to be altered. This altered pattern of methylation can be …

Exploring The Potential For Electromangetophoretic Separation, Thomas Lewis
Exploring The Potential For Electromangetophoretic Separation, Thomas Lewis
Chemical Engineering Undergraduate Honors Theses
Current research in mircofluidic technology is underway to develop automatic micro-analyzing chips for medical diagnostic testing. Diagnostic testing often requires separation of specific biological particles from a sample, and many of these molecules contain electric or magnetic properties. This project investigates the potential for separation in electromagnetophoretic and magnetophoretic microfluidic technology. In electromagnetophoresis, the Lorentz force acting on a current carrying medium in a homogeneous magnetic field creates a pressure gradient in the fluid, resulting in an applied force to particles present in the separation medium. This force causes the particle to have a velocity component that is perpendicular to …

A Study Of Inhomogeneity Effects On Packed High Performance Liquid Chromatography Columns, Tyler House
Chemical Engineering Undergraduate Honors Theses
The packing quality of a High Performance Liquid Chromatography column has significant impact on the resulting separations. In practice, problems in a packing occur through normal usage of a column. Resulting chromatograms from inhomogeneities exhibit varying problems such as extreme tailing and double peaks. Early detection of such problems is critical to fixing problems before their effect harms efficiency, but a fully developed theory of how inhomogeneities affect separations does not exist. The purpose of this work was to experimentally characterize HPLC column inhomogeneities and to begin preliminary simulations of HPLC columns with the computer simulation package STAR-CD. To do …

Ultrafiltration Membrane Process For Pyrogen Removal In The Preparation Of Water For Injection (Wfi), Thet N. Soe
Ultrafiltration Membrane Process For Pyrogen Removal In The Preparation Of Water For Injection (Wfi), Thet N. Soe
Inquiry: The University of Arkansas Undergraduate Research Journal
An artificial kidney process based on ultrafiltration (called hemodiafiltration) more effectively removes blood toxins, particularly those of higher molecular weight, than conventional dialysis. In hemodiafiltration, replacement liquid must be added directly to the patient's blood to replace liquid filtered out of the blood in the ultrafiltration cartridge. This replacement liquid is made up of' "water for injection" (WFI) and other components such as salts and glucose. WFI is produced either by distillation or reverse osmosis and has a cost of $1.00 per liter. A patient with kidney problems would require three hemodiafiltration treatments per week, each requiring 70-80 liters of …

Inquiry: The University of Arkansas Undergraduate Research Journal
Consumption of raw or lightly cooked alfalfa sprouts has been a concern of the U.S. Food and Drug Administration (FDA) in recent years due to connections between sprouts and foodborne illnesses. Researchers have identified, contaminated seeds as the primary source of alfalfa sprouts contamination. Contamination of alfalfa seeds can originate in the field, harvesting, storing, or sprouting. Two pathogens of particular concern on alfalfa seeds are Escherichia coli 0157:H7 (E. coli) and Salmonella. These pathogens are capable of producing biofilms that provide protection for individual cells and allow for survival in otherwise hostile environments, including some disinfectant washes. Other factors …

Extraction Of Silymarin Compounds From Milk Thistle (Silybum Marianum) Seed Using Hot, Liquid Water As The Solvent, J.F. Alvarez Barreto
Inquiry: The University of Arkansas Undergraduate Research Journal
High value specialty chemicals are usually obtained from natural products by extracting with generally regarded as safe (GRAS) solvents. Because organic solvents are quite often used, high operating and disposal costs often occur. When compared to traditional solvents, water can be viewed as an interesting alternative because of its low operating and disposal costs. Milk thistle contains compounds (taxifolin, silychristin, silydianin, silybinin A and silybinin B) that display hepatoxic protection properties. This paper examines the batch extraction of silymarin compounds from milk thistle seed meal in 50'C, 70'C, 85'C and 100'C water as a function of time. For taxifolin, silychristin, …
