An Estimation Of Available Cellulosic Biomass In Ten Counties In Northeastern Arkansas From 1999-2011, Thomas Jenkins
An Estimation Of Available Cellulosic Biomass In Ten Counties In Northeastern Arkansas From 1999-2011, Thomas Jenkins
Biological and Agricultural Engineering Undergraduate Honors Theses
The purpose of this research is to explore the possibility of siting a biorefinery that produces cellulosic ethanol in the Delta region of Arkansas, which is the main agricultural area of the state. Four major crops that the state of Arkansas produces on a yearly basis that could potentially be used for cellulosic ethanol production are: corn, rice, sorghum, and soybeans. This research will result in the generation of maps that will be useful in quantifying feedstock produced in the Delta region of Arkansas, which can be used by a biorefinery. An actual site will not be chosen based strictly …
Varying Culture Conditions To Enhance Tissue Formation, Katherine Atkins
Varying Culture Conditions To Enhance Tissue Formation, Katherine Atkins
Biological and Agricultural Engineering Undergraduate Honors Theses
For severe muscle damage, tissue engineering has become a viable option to culture muscle tissues with the ultimate goal of implantation. However, the tissues are typically cultured on permanent scaffolds which would elicit a foreign body response if placed in the body. To avoid this, biological scaffolds are ideal for tissue culture and limiting any negative reactions. A sacrificial scaffold can be used to gather extracellular matrix (ECM), which can then be used as the primary scaffold for culturing tissues for implantation. To reach the ultimate goal of implanting muscle tissue, an understanding of how to produce ECM on a …

The Effect Of Cell Density And Cultivation Period On Skeletal Muscle Extracellular Matrix Accumulation, Ryan Yarnall
Biological and Agricultural Engineering Undergraduate Honors Theses
Traumatic skeletal muscle injuries have led to severe disability disallowing one to perform necessary daily tasks. Different methods are under current research to rebuild muscle tissue and have it function properly. One such method is the use of extracellular matrix, or ECM, retrieved from cells to create biological scaffolds providing structure for myoblast cells to grow into tissue. This research holds promise because it utilizes the body’s own machinery, minimizing risk of a foreign body response. To obtain ECM scaffolding, one viable technique involves the cultivation of cells on polyurethane foams to collect and harvest ECM. This research investigates the …

Structural Characterization Of Engineered Muscular Mimetic, Nadia Bhatti
Biological and Agricultural Engineering Undergraduate Honors Theses
An engineered muscular mimetic (EMM) was synthesized, and its overall structure—porosity, average pore size, and pore alignment—was characterized and compared to actual decellularized skeletal muscle (DSM). The EMM’s porosity was about 20% more and average pore size was about 85% smaller compared to that of the DSM. Unlike the strong horizontal pore alignment in the DSM, no distinct orientation could be identified in the EMM structure.
Minimizing Wash Water Usage After Acid Hydrolysis Pretreatment Of Biomass, Noaa Frederick
Minimizing Wash Water Usage After Acid Hydrolysis Pretreatment Of Biomass, Noaa Frederick
Biological and Agricultural Engineering Undergraduate Honors Theses
Abstract Dilute acid pretreatment, needed to prepare biomass for saccharification, results in the production of a number of byproducts, which inhibit subsequent enzymatic hydrolysis and fermentation steps. In order to improve saccharification yields in the enzyme hydrolysis step, the pretreated biomass is often rinsed with room temperature water to remove these byproducts. High-density poplar was pretreated with 1% dilute sulfuric acid at 140 ºC for 40 minutes. After pretreatment the biomass was washed with water volumes equal to 0, 1 ½, or 3 times the biomass volume. The rinsed biomass was then enzymatically hydrolyzed and the concentrations of byproducts and …
Scaffolding For Human Pluripotent Stem Cell Lineage Specification, Thanh Dai
Scaffolding For Human Pluripotent Stem Cell Lineage Specification, Thanh Dai
Biological and Agricultural Engineering Undergraduate Honors Theses
Current research regarding stem cells is the premise behind this project. These cells have the potential to develop into any kind of cell in the human body. Due to the scarcity of transplantable pancreas and/or pancreatic beta cells, the production of pancreatic insulin-producing cells from human embryonic stem cells (hESCs) has emerged as one of the most attractive cell therapy strategies for insulin deficient diabetes treatment. The aspect of hESC research that the project focused on was the environment or foundation the hESCs grew in. A key step to pancreatic beta cell production from hESC differentiation or growth is establishing …
