How Math And Music Jams Together, Felicia Bell Apr 2012

How Math And Music Jams Together, Felicia Bell

Undergraduate Student Symposium

For centuries, mathematicians have been trying to analyze and model music. Music can be described and analyzed through quite a few equations which are based on trigonometric functions, derivatives and integration. A wave equation can be used to represent harmonic notes such as a vibrating string from a guitar. A single tone can be described by a sine function, while multiple notes played together can be described by the sum of each single tone. Processing a piece of music as a signal, the theory of Fourier Transform can identify each note and its amplitude or volume.

Loss Of 125i-Sarcosine1, Isoleucine8 Angiotensin Ii Binding In The Brain Of Neurolysin Knock-Out Mice, Jamala D. Swindle, Luz Gonzalez, Andrea Linares, Kira L. Santos

Undergraduate Student Symposium

The brain renin-angiotensin system profoundly affects the cardiovascular system, often with pathological consequences. However, many unresolved questions about its functionality remain. Recently it was shown that a novel, non-AT1, non-AT2 binding site for angiotensin II (Ang II) exists in the mammalian brain. This protein has been identified as the metalloendopeptidase neurolysin (E.C.3.4.24.16). To assess the localization of this binding site in mouse brain, 3 mice deficient in neurolysin as well as 3 wild-type mouse brains were evaluated for radioligand binding with 125I-Sarcosine1,Isoleucine8 Ang II (250 pM) in the presence of receptor-saturating concentrations of …

The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero Apr 2012

The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero

Undergraduate Student Symposium

Porphyrins differ in the nature of their peripheral substitution; β substituted are known as natural porphyrins and meso substituted as synthetic porphyrins. Within the meso substituted porphyrins we studied the H2pOH-TPhP. The UV absorption spectra of this porphyrin is observed and monitored between 350 and 750 nm. The resulting absorption spectra after the creation of the dianion and dication with the respective titrations using NaHCO3/HCl and NaOH/HCl will be explained based on the position of the OH in the phenyl group and contribution to the formation of the respective dication or dianion.

The Proposal: Show Her Who's Boss, Alison Parente

Undergraduate Student Symposium

This essay identifies the romantic and screwball comedy elements within the film The Proposal, while simultaneously relating the motion picture to women's issues. This piece argues that though The Proposal is eclectic in style, it is ultimately a film that proposes nothing new to audiences, and in fact is regressive in nature with respect to its reinforcement of clichéd gender roles and stereotypes.

Porous Compounds As Drug Transfer Agents, Angelo J. Capobianco Apr 2012

Porous Compounds As Drug Transfer Agents, Angelo J. Capobianco

Undergraduate Student Symposium

For a while now there has been an interest in porous compounds to act as transfer agents for other compounds. Porous compounds are defined as such because the molecular structure of these compounds so as there is empty space, or a channel between each molecule of the compound. Therefore, the more molecules that the compound has, the more channels exist and the compound is more porous. The channels in these molecules allow molecules from other compounds, or guest molecules to become locked inside of the porous material. The compound being studied in this experiment is a solid, crystalline compound created …

A Case Of Mistaken Identity In The Pathogenesis Of Type 1 Diabetes, Lynette Miller Apr 2012

A Case Of Mistaken Identity In The Pathogenesis Of Type 1 Diabetes, Lynette Miller

Undergraduate Student Symposium

This paper will review what happens physiologically when the body’s immune system mistakenly attacks the insulin-producing beta cells of the pancreas, resulting in the onset of Type 1 Diabetes Mellitus. The immune system is designed to fight infection and viruses, but in the case of diabetes, it responds inappropriately by targeting normal body cells and tissues. The hormone insulin is produced by specialized islet cells in the pancreas and is essential for glucose metabolism. When the body does not produce insulin, it cannot control blood glucose levels and therefore, patients must rely on subcutaneous insulin injections or continuous infusion with …

Characterization Of The Uv Absroption Spectra Of N-Methylpyrydil Porphyrins, Kevin Winters Apr 2012

Characterization Of The Uv Absroption Spectra Of N-Methylpyrydil Porphyrins, Kevin Winters

Undergraduate Student Symposium

Protonation of phenyl porphyrins induced by THF has been investigated. After ionization, the positive charge was localized in the π-electron system. UV spectras have been studied for the ortho, meso, and para cation positions. Upond acid treatment of N-methyl-2-pyridyl, and N-methyl-3-pyridyl, the soret peak and Q bands showed a shlight red shift, signifying a lowering of energy levels of the excited and unexcited states of the π-electrons. However, the soret peak and Q bands of N-methyl-3-pyridyl showed a slight blue shift. This accounted for the increased solvation of π-electrons at the meso position, which increased the energy level difference between …

Comparative Neurogenesis In The Brain Of The Adult Mayan Cichlid, Ahmed Ali, Kelsey Bragg, Catalina Breton, William Kotkin, Jonathan Romanes

Undergraduate Student Symposium

Neural progenitor cells are the only cells in the adult brain that continue to proliferate, migrate, and integrate into existing neural networks throughout the life-span of all mammals examined to date, including humans. Understanding how neurogenesis (the birth of new neurons) is regulated has exciting therapeutic potential for a wide range of central nervous system diseases. Neural progenitor cells exist in two neurogenic regions of the adult mammalian brain: the dentate gyrus of the hippocampus and the forebrain subventricular zone. In recent studies, postnatal neurogenesis has been reported in several regions of the fish brain including the olfactory bulb, optic …

Population Densities Of Porites Sverdrupi, A Coral Limited To The Mexican Eastern Tropical Pacific, Eduardo Carrera Apr 2012

Population Densities Of Porites Sverdrupi, A Coral Limited To The Mexican Eastern Tropical Pacific, Eduardo Carrera

Undergraduate Student Symposium

Porites sverdrupi is a rare, endemic free living coral that only inhabits the Mexican Eastern Tropical Pacific at depths typically between 20 and 40 meters. Until recently it was considered an ecomorph of the more abundant congener Porites panamensis, so there are few studies focused solely upon this species. The volatility of the populations of corals in this region and a continually decreasing habitat has led some researchers to conclude that P. sverdrupi may be undergoing a natural process of extinction. This study initiates a multi-year analysis of the population trend of P. sverdrupi off the coast of Isla …

The Epistemological Status Of Theoretical Simplicity, Yineth Sanchez Apr 2012

The Epistemological Status Of Theoretical Simplicity, Yineth Sanchez

Undergraduate Student Symposium

In this paper, I argue that theoretical simplicity is not an epistemic virtue. Therefore, we need not prefer the simpler explanation of two competing scientific theories. First, I clarify the concept of theoretical simplicity as it figures into discussions in the philosophy of science. Next, I evaluate the strongest arguments in favor of this view as a criterion of theory selection. Then, I present two instances where theoretical simplicity is not preferable as such a criterion. Lastly, I show that while there may be a number of nonepistemic criteria of theory choice, including simplicity, none of them bears upon truth. …
