Construction Of A Polyphosphate Kinase Gene Deletion In Yersenia Spp., Shan Desai Apr 2011

Construction Of A Polyphosphate Kinase Gene Deletion In Yersenia Spp., Shan Desai

Undergraduate Student Symposium

The goal of this experiment is to study the bacteria, Yersinia pestis, Yersenia enterocolitica, and Yersenia pseudotuberculosis, and the possible role of the enzyme polyphosphate kinase (PPK) in pathogenicity, motility, and gene expression. PPK is an enzyme that produces inorganic polyphosphate, which is universal and found in all forms of life from prokaryotic bacteria to eukaryotic mammals. The PPK enzyme has been shown to be required for motility and virulence of several pathogenic bacteria. Yersinia spp. are diverse bacteria that cause diseases ranging from gastrointestinal diseases to bubonic plaque; however, the role of PPK is unknown. …

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos Apr 2011

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos

Undergraduate Student Symposium

Bilingualism has been linked to enhanced cognitive abilities and these enhanced abilities are believed to be mediated by the same frontal lobe system that controls language output in bilinguals. Moreover, recent research suggests that this bilingual advantage may be moderated by degree of balance between the two languages such that those who are equally proficient in their two languages show the best performance on cognitive tasks compared to unbalanced bilinguals and monolinguals. For instance, results from one study revealed that balanced bilinguals showed significantly fewer errors on the Wisconsin Card Sorting Test (WCST) than unbalanced bilinguals. Thus, the purpose of …

Chemical Interactions Between Staphylococcus Aureus And Candida Albicans Within Mixed Species Biofilms, Rachel Comito, Fiorella Diaz, Martin Herrera, Ariel Jordan Apr 2011

Chemical Interactions Between Staphylococcus Aureus And Candida Albicans Within Mixed Species Biofilms, Rachel Comito, Fiorella Diaz, Martin Herrera, Ariel Jordan

Undergraduate Student Symposium

Biofilms are communities of microbes that grow and function together in order to gain protection from environmental stressors. Staphylococcus aureus and Candida albicans are two of the most common microbes found to grow as biofilms within medical facilities and are among the leading causes of infectious disease. Previous studies found that S. aureus and C. albicans grow together synergistically within biofilms and that S. aureus actually secretes some chemical that drastically improves candidal biofilm growth. The current project is focused on better characterizing the mechanism of this chemical interaction. One aspect of the project examines when S. aureus secretes this …

Budding Brain, Kurshaad Cheenibas, Smit Patel, Adam Adbulhafid, Patrick Cao

Undergraduate Student Symposium

Mathematics is used to illuminate the world around us by describing what we see through various models. Models can range from simple linear models of gravity and line weaver Burk to complex models such as models of storms. Simple models are easy to use but lack the accuracy in prediction that more complex model provide. The difference between this dynamic model and statistical model are descriptive while dynamic model are predictive. Descriptive model make sense of data and predictive model use the data you have to make prediction. This research seeks to uncover cross disciplinary nature of dynamic model and …

A Cardiac Arrhythmogenesis Model: Spiraling Out Of Control, Rajeswari Murugan Apr 2011

A Cardiac Arrhythmogenesis Model: Spiraling Out Of Control, Rajeswari Murugan

Undergraduate Student Symposium

Arrhythmic Sudden Cardiac death accounts for up to 5 million cases per year across the world. Cardiac arrhythmia is an abnormal activity in the heart that can lead to sudden cardiac death resulting from ventricular fibrillation. The electrocardiogram (ECG) reading during an arrhythmia indicates rapid contractions of the heart. This phenomenon is due to the development of a re-entrant circuit of electrical activity that repetitively stimulates the heart. The heart presents a spatio-temporal complex system, where the tissue biophysics and structure leads to reaction diffusion type models. These models portray the re-entrant wave patterns observed during arrhythmia. Fibrillation is characterized …

The Study Of Lagenidium Giganteum Crinkler Genes, Alexa Vyain, Tulsi Patel

Undergraduate Student Symposium

Lagenidium giganteum is an entomopathogenic oomycete that is known to infect and kill the larvae of mosquitoes. Due to this characteristic, the organism has been deemed a potential alternative to chemical insecticides. This information is significant when the world issue of mosquito control is considered. The human death toll now reaches one million per year by mosquito-borne diseases, and the research on potential alternatives to chemical insecticides is quite minimal. Only seven L. giganteum protein-coding gene sequences have been reported to date, and the objective of this project is to accelerate the gene research of L. giganteum and identify the …

Tmnt: Dynamic Models Of Cancer And Hiv, Christina Gobin, Emily Nguyen, Fayssa Salomon, Arash Nasajpour Apr 2011

Tmnt: Dynamic Models Of Cancer And Hiv, Christina Gobin, Emily Nguyen, Fayssa Salomon, Arash Nasajpour

Undergraduate Student Symposium

Differential equations are used to build dynamic mathematical models for systems and nonlinear phenomena, which dynamically change with time. Ordinary differential equations describe a relation that contains functions of only one independent variable, and one or more of their derivatives with respect to that variable. Applications of those models are found in biological systems. In one study, homogeneous mathematical models are used to describe the interactions between cancerous cells and the immune system. Modeling using differential equations will allow better understanding of the behavior and spreading of those malignant cells. The models will investigate the dynamics of populations of cancer …

The Impact Of Psychological Stress On An Acute Stress Challenge: An Investigation Into Biochemical, Social And Personality Correlates, Tatiana Viena, Isabelle Barbu Apr 2011

The Impact Of Psychological Stress On An Acute Stress Challenge: An Investigation Into Biochemical, Social And Personality Correlates, Tatiana Viena, Isabelle Barbu

Undergraduate Student Symposium

Stress exposure activates a variety of physiological coping systems. While acute stress responses are considered important for healthy coping, overexposure to stress results in an alteration of the functioning of the stress (HPA) axis, leading to a variety of deleterious psychological and physiological effects. For that reason, understanding and explaining these mechanisms is essential. Here, we sought to determine whether chronic psychological (examination) stress would result in a decreased ability to mount an acute stress and immune response. We also assessed locus of control and social support measures. Thirty subjects participated in 2 sessions (baseline and examination week) in which …

Singles View Other Singles As Sexy: The Influence Of Relationship Status On Judgments Of Attractiveness, Jenna Wells Apr 2011

Singles View Other Singles As Sexy: The Influence Of Relationship Status On Judgments Of Attractiveness, Jenna Wells

Undergraduate Student Symposium

Previous studies on whether people find single or non-single opposite-sex targets more attractive are inconsistent (e.g., O’Hagen et al., 2003; Bressan & Stranieri, 2008; Uller & Johansson, 2003); these effects may vary according to social and hormonal factors (e.g., Gangestad et al., 2004). We propose that participants’ own relationship status may influence their judgments of the attractiveness of single and non-single people. In the present study, 43 participants each rated the attractiveness of ten “profiles,” using a between-participants design. Each profile consisted of a photograph and short personal description of a young opposite-sex adult. Half the profiles were depicted as …

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella Apr 2011

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella

Undergraduate Student Symposium

This paper focuses on the poetic techniques of two Beat poets, Lenore Kandel and Allen Ginsberg, whose impressionistic, caustic poetry is in some ways representative of the entire Beat movement. Kandel's poems ring with overt sexual overtones, seemingly unconcerned with respect to morality or grace, invoking instead shocking and disturbing images. In her poetry is an intrepid protest of violence and conformity through the paradoxical use of violent description. Like the other Beat poets, she often refused to compromise in either structure or content, adopting a flowing, free-verse form. Allen Ginsberg's poetry employs the same modes: free verse, shocking context, …

The Language Of Mathematics: Proof Without Words, Bryan Candela Apr 2011

The Language Of Mathematics: Proof Without Words, Bryan Candela

Undergraduate Student Symposium

Mathematics is the language of the sciences. Unlike most other scientific laws, mathematical laws are by nature unbiased and irrefutable, and as such, tend to be accepted as truth in a way that other scientific laws cannot. While understanding the proofs of many well-known mathematical facts requires a high level of mathematical maturity, there are also many (perhaps not so intuitive) facts whose proof can be easily understood by anyone. The goal of this project is to show the use of mathematics as a language in the hope of providing insight into the beauty of mathematics.

A Look Into Abstinence Only Sex Education Vs. Comprehensive Sex Education, Katrin Scheurer Apr 2011

A Look Into Abstinence Only Sex Education Vs. Comprehensive Sex Education, Katrin Scheurer

Undergraduate Student Symposium

For almost two decades between the years of 1990 and 2010, many schools in the US were educating their young people on sex via abstinence only programs. Abstinence only sex education means that when students are taught in school about sex that they are taught abstinence is the only way (Barnett & Hurst, 2003). In comprehensive sex education the students would be taught more information about different contraceptives, sexual health and sexual decision making (Barnett & Hurst, 2003). In February, 2010, after years of federal funding for abstinence only sex education, President Obama cut this budget by $170 million. The …

Standardization Of A Technique For Quantification Of Glutathione Concentration In Human White Blood Cells: A Biomarker For Autism?, Luis Puchi, Reina Miranda Apr 2011

Standardization Of A Technique For Quantification Of Glutathione Concentration In Human White Blood Cells: A Biomarker For Autism?, Luis Puchi, Reina Miranda

Undergraduate Student Symposium

Glutathione is an unusual tripeptide ubiquitous in scientific literature for its antioxidant capacity and its relevance as an indicator of oxidative stress. Glutathione’s role within cellular homeostasis is well documented, but the entirety of glutathione’s biochemical role within the human body remains fervently researched. Deficiencies in glutathione have been linked to patients suffering from a wide spectrum of disorders including, cancer, cardiovascular diseases, and autism (Pastore, Federici, Bertini, & Piemonte, 2003). Much of the research on glutathione centers on the relationship between the reduced (GSH) and oxidized (GSSG) versions of the tripeptide. Fluctuations which lower the ratio of GSH to …

The Real Within The Dream, Jessica Furth, Christopher Garcia, Natasha Matijasevic Apr 2011

The Real Within The Dream, Jessica Furth, Christopher Garcia, Natasha Matijasevic

Undergraduate Student Symposium

Latin American modernist authors were inspired by European surrealists to craft their own experimental style, magical realism. In his short story, “The Night Face Up” ("La Noche Boca Arriba"), Argentine author Julio Cortázar employs magical realism to alter the reader’s perception of the “real” and the “dream” world. The story opens with an unnamed protagonist who gets into a motorcycle accident. The remainder of the story alternates between scenes from his hospital bed and scenes from a presumed dream, where he is a Motecan warrior running from the Aztecs. The reader is expected to believe that the hospital scene constitutes …

Exploring The Formation Of Novel Organic Compounds In Urban Atmosphere, Melanie Campbell Apr 2011

Exploring The Formation Of Novel Organic Compounds In Urban Atmosphere, Melanie Campbell

Undergraduate Student Symposium

It has been reported that the atmosphere surrounding Shanghai and other eastern Asian cities contain a surprisingly large amount of formaldehyde and other carbonyl compounds as well as amines, which are the byproducts of industrial sources. In theory, formaldehyde can react with primary or secondary amines and these additional carbonyl compounds containing acidic protons to form novel organic compounds, such as organic salts, through a process known as a Mannich reaction. In this research project, different types of Mannich reactions were performed in the lab by using several organic precursor compounds, some readily found in the atmosphere in Shanghai, to …

Experimental And Numerical Determination Of Phase Synchronization Between A Chua System And An External Periodic Signal, Yaneve Shemesh Apr 2011

Experimental And Numerical Determination Of Phase Synchronization Between A Chua System And An External Periodic Signal, Yaneve Shemesh

Undergraduate Student Symposium

We present our first experimental results in relation to the phase synchronization of a single sinusoidal function to a Chua oscillator. We approached the synchronization process with real time observation. We were able to observe that a Chua oscillator will stay phase synchronized if the periodic signal has the appropriate amplitude and frequency, i.e., falls inside a synchronization tongue (Arnold Tongue). These early results will be compared in the future with numerical simulations.

The Distribution Of Two Sea Pens (Pennatulidae) In The Sw Gulf Of California, Mexico With Reference To Predation, Angelica M. Garcia Apr 2011

The Distribution Of Two Sea Pens (Pennatulidae) In The Sw Gulf Of California, Mexico With Reference To Predation, Angelica M. Garcia

Undergraduate Student Symposium

Sea pens (Pennatulidae) are sessile, benthic cnidarians that inhabit soft sediment, and rely on filter feeding to obtain energy. They have a central stalk (rachis) which contains secondary polyps for feeding. Since no previous data has been collected on their distribution, abundance or size in the SW Gulf of California, Mexico, benthic surveys were conducted at depths of 11.0 - 32.6 m near Isla San Fransiscito and El Pardito. Two species (Stylatula elongata and Ptilosarcus undulatus) were observed. The average height ± s.d. (tip to sediment surface) of S. elongata was 9.5 ± 3.8 cm (n=37) and was …

A Tale Of African Dust: Cross-Oceanic Transport And Climatic Impact, Calista Ming Apr 2011

A Tale Of African Dust: Cross-Oceanic Transport And Climatic Impact, Calista Ming

Undergraduate Student Symposium

Aerosols are believed to partially counteract greenhouse warming effects and can also cause harm to human health, although the detailed mechanisms are not fully understood. A major reason for this is the lack of knowledge of the composition, origin and evolution of these aerosols. In order to better understand these issues, field research was carried out at Ragged Point, Barbados, during the summer of 2010. The sampling site is the eastern most point in the Caribbean region and the first land contact for dust aerosols that originate in Africa and travel transatlantic to the Caribbean and Floridian regions. Aerosol samples …

Providing Attorneys For Children In Dependency And Termination Of Parental Rights Proceedings In Florida: The Issue Updated, Michael J. Dale

Faculty Scholarship

Florida's system for providing protection and safety to children in the State's child welfare system has changed over the past decade. Regretfully, the changes do not appear to have had a significant impact in two areas: increasing the safety and protection of children in the system' and providing children with independent attorneys to advocate on their behalf. Investigations, lawsuits, grand juries, amendments to court rules, and newspaper articles continue to demonstrate the myriad failures in the Florida system. Two notorious examples hi-lite the shortcomings: the cases of the foster child, Rilya Wilson, who disappeared in 2001, and Gabriel Myers, who …
