Life Behind Glass: Bioreactor Studies On The Salt-Water Adaptation Of Scenedesmus Dimorphus, Joshua Hartranft, Alex Fedai, Sahar Ataya

Undergraduate Research Posters 2016

Algae has considerable promise as source for liquid biofuel because of high productivity and because algae farms do not compete with food crops for arable land. Freshwater algae is preferred over saltwater algae because of the higher lipid content in the former. Unfortunately, freshwater algae “farms” would require a vast amount of fresh water, and given the scarcity of fresh water, this is not a viable long-term solution. Therefore, the adaption of a fresh-water species of algae to a salt-water environment is a potential solution. In this study, it was shown that the growth rate of the freshwater algae S. …

Glycerolipid Analysis Of Adaptation To Saline Changes In The Culture Conditions Of Algae, Scenedesmus Dimorphus, By Gc-Ms, Tyler Fitzgerald, Satya Girish Chandra Avula, Chandana Mannem

Undergraduate Research Posters 2016

Since fossil fuels are decreasing over time an alternative energy source will be soon required. The algae, Scenedesmus dimorphus, grows in freshwater and is known for its fast growth of glycerolipid content which is used for biodiesel production. After the algae is grown in optimal conditions, the released fatty acids and glycerolipids are transformed into fatty acid methyl esters (FAMEs) which are used as biodiesel. The FAMEs were quantitatively determined by gas chromatography mass spectrometry (GC-MS) to determine the total glycerolipid content in the different algae samples. The samples that were analyzed include freshwater controls and saline adapted samples. Analysis …

Design And Fabrication Of A Microfluidic Device Using A 3d Printer, Aaron Smith

Undergraduate Research Posters 2016

The goal of this work was to design and implement a microfluidic mixer-based chemical reactor using a 3-D printer. Microfluidic devices are very useful for processes that use expensive reactants or require a high level of control, and we hypothesize that the ability to develop a prototype using a 3-D printer would lower their costs and help overcome some of the limitations of soft-lithography based devices. One-level and two-level designs were made using SolidWorks® software, and various stages of the model were printed on Objet® and FDM® printers. The Objet printer offers the advantage of printing a prototype using a …

Scalable Assembly Of Nanoparticles Onto Templated Substrates, John Juchnowski

Undergraduate Research Posters 2016

Anisotropic nanoparticles, such as carbon nanotubes and noble metal nanorods, have excellent electrical, mechanical, and thermal properties. This work examined techniques for the nanopatterning of silicon substrates for the subsequent deposition of anisotropic nanoparticles in order to exploit their properties in macroscopic applications. Argon-ion-sputter induced rippling of Si (100) as well as a microparticle mask were examined as methods for templating a silicon substrate. For the ion-sputter

Light Scattering Characterization Of Elastin-Like Polypeptide Trimer Micelles, Ilona Tsuper, Daniel Terrano, Adam Maraschky

Undergraduate Research Posters 2016

Elastin-Like Polypeptides (ELP) can be used to form thermo-reversible vehicles for drug delivery systems. The ELP nanoparticles are composed of three-armed star polypeptides. Each of the three arms extending from the negatively charged foldon domain includes 20 repeats of the (GVGVP) amino acid sequence. The ELP polymer chains are soluble at room temperature and become insoluble at the transition temperature (close to 50 oC), forming micelles. The size and shape of the micelle is dependent on the temperature and the pH of solution, along with the concentration of the Phosphate Buffered Saline (PBS) solvent. The technique of Depolarized Dynamic Light …

Light Scattering Study Of Mixed Micelles Made From Elastin-Like Polypeptide Linear Chains And Trimers, Ilona Tsuper, Daniel Terrano, Adam Maraschky

Undergraduate Research Posters 2016

Temperature sensitive nanoparticles (E20F) were generated from a construct of three chains of Elastin- Like Polypeptides (ELP) linked to a negatively charged foldon domain. This ELP system was mixed at different ratios with a single linear chain of ELP (H40L) which was deprived of the foldon domain. The mixed system is soluble at room temperature and at a transition temperature will form swollen micelles with the hydrophobic linear chains hidden inside. This system was studied using Depolarized Dynamic Light Scattering (DDLS) and Static Light Scattering (SLS) to model the size, shape, and internal structure of the mixed micelles. The mixed …

Feasibility And Effects Of Accelerometer Based Feedback On Paretic Upper Extremity Amount Of Use In The Home Setting In Subjects Chronic Post-Stroke, Nathan Pohl, Amber Kuehn, Mishgan Abdullah

Undergraduate Research Posters 2015

Purpose : to (1) evaluate the feasibility of using accelerometers in the home to quantify how much subjects chronic post-stroke (PS) use their upper extremities (UE), (2) measure differences between amount of UE movement in subjects PS and a healthy control group (HC), (3) determine the effects of accelerometer based feedback on paretic UE use in subjects PS, and (4) determine if those effects are retained over time. Methods : Six subjects PS wore accelerometers for 3 weeks with two feedback sessions given during week two. Seven HC subjects wore accelerometers for one week. Accelerometer based outcome measures included relative …

Effects Of Accelerometer Based Feedback On Clinical Measures And Paretic Upper Extremity Amount Of Use In Subjects Chronic Post-Stroke, Amber Kuehn, Nathan Pohl, Mishgan Abdullah

Undergraduate Research Posters 2015

Purpose/Hypothesis: To determine the effects of accelerometer based feedback on clinical measures of paretic upper extremity (UE) recovery in people post-stroke and examine the relationship between these changes and paretic UE amount of use (AOU) measured by an accelerometer. Subjects: 7 people chronic post-stroke (5 males, 2 females; aged 62.03 ± 11.33 years) with an Upper Extremity Fugl-Meyer score range of 10-63 were included for this poster. Materials/Methods: Subjects wore wrist accelerometers for 3 weeks in the home. Clinical measures (Motor Activity Log, Stroke Impact Scale, Chedoke Arm and Hand Activity Inventory, and the ABILHAND) were assessed weekly. Data analysis …

Sound And The Moving Image:Critical Characteristics For Spectator Response, Kara Rader, Rafeeq I. Roberts, Matt Egizii, Jeffery Allen

Undergraduate Research Posters 2013

The prevailing wisdom in the film and video production industries is that audio information outweighs visual information when it comes to spectator responses, but there are few empirical studies to support this claim. In previous research, four critical characteristics of sound have been identified: (1) Music, (2) visual/sound contradictions (defined as sound that is inconsistent with audience expectations based on visual information), (3) multi-channel sound, and (4) sound quality. Building on our previous research into music and film, we have found that many researchers have looked into the question of how music affects emotions (Eschrich et al., 2008; Have, 2008; …

Role Of Programmed Proteolysis During Meiosis, Vincent Matthews, G. Valentin Borner Ph.D.

Undergraduate Research Posters 2013

Meiosis is the process which forms gametes and spores for reproduction in eukaryotic cells. During the pachytene phase of meiosis I, a protein structure, called the Synaptonemal Complex (SC), forms between homologous chromosomes and creates a scaffold for genetic recombination. In yeast, the Zip1 protein is a major structural component of the SC. At restrictive temperature for meiosis, ZIP1 is required for completion of meiotic divisions. At permissive temperature ZIP1 is required for proper chromosome segregation. We observed that chemical inhibition of the proteasome, with MG132, results in arrest at prophase of meiosis I. Based on these results, we questioned …

Adaptation Of Scenedesmus Dimorphus To Brackish Water, Dustin Bowden, Joanne M. Belovich

Undergraduate Research Posters 2013

Microalgae is a promising biofuel feedstock for replacement of conventional transportation fuels. Microalgae does not require arable land for cultivation, and the biofuel production rate per acre of land is an order of magnitude greater than that needed for crop-based production methods. Though microalgae to biofuel processes are attractive, none have proven commercially successful due to the high costs of algae dewatering. Moreover, the scarcity of fresh water in many parts of the world prevents development of this process because of competition with drinking water supplies. Our lab has developed an efficient dewatering method using an inclined gravity settler. It …
