Analyzing Hotel Room Cleanliness On A Microscopic Level, Ahmad Khalid, Kodi Stevens Apr 2011

Analyzing Hotel Room Cleanliness On A Microscopic Level, Ahmad Khalid, Kodi Stevens

Undergraduate Student Symposium

The cost of a hotel room is usually correlated to the quality of the hotel room and the quality of services provided during one’s stay; e.g. the cleanliness of the room and the thoroughness of the cleaning staff. The cleaner a hotel is the more desirable it is. The goal of this experiment was to analyze hotel cleanliness at the microscopic level to determine if pathogenic micro-organisms were present. Samples were taken from telephones, toilet seats, remotes, toilet flushers, bath tubs and doorknobs from five different hotels and grown at room temperature on nutrient agar plates, counted and then isolated. …

The Impact Of Speed Reading On The Generation Of Inferences, Anil Sawh Apr 2011

The Impact Of Speed Reading On The Generation Of Inferences, Anil Sawh

Undergraduate Student Symposium

This experiment explores the effect that speed-reading has on the inferences made while reading texts. More specifically it will compare comprehension and inferences made between participants that read at a normal rate and participants that have been trained to read at a faster rate than normal. Speed-reading courses promise the ability to learn how to take in larger amounts of text and information than normal reading. However, most research has shown that while these courses increase reading speed, comprehension and retention of the material suffers a significant drop (Just, Carpenter, & Masson, 1986). Very little research has examined the effects …

The Effect Of Thimerosal-Containing And Thimerosal-Free Pediatric Flu Vaccine On Gene Expression In Saccharomyces Cerevisiae, Christie Rubio

Undergraduate Student Symposium

Mercury-based preservatives including thimerosal, typically added to some vaccines, may pose health concerns as mercury toxicity has been implicated in many human diseases. In this study, microarray technology and reverse transcriptase-polymerase chain reaction (RT-PCR) were used to examine the potential effects of a typical dose of thimerosal-containing vaccine (TCV) or thimerosal-free (TFV) pediatric flu vaccine on gene expression in Saccharomyces cerevisiae, a model organism that shares roughly 30% of its genome with humans. Yeast were grown in three treatments: standard media (YEPD), YEPD plus TCV, and YEPD plus TFV. Microarray gene expression data were examined for variability both within …


The Effects Of Categorization On Memory, Logan Armstrong Apr 2011

The Effects Of Categorization On Memory, Logan Armstrong

Undergraduate Student Symposium

The purpose of this study was to explore the effects of categorization on our ability to remember events and objects. This is an important question because little research has tested the notion that the ability to categorize helps produce better memory. Morris & Baker-Ward (2007) studied a similar question when they examined whether having the vocabulary to describe an experience affected the ability to remember that experience. Specifically, they tested whether infants who had learned their colors prior to participating in an experiment involving different colored bubbles would recall the experiment better than those who learned the colors after the …


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 …


On Parmenides’ Reality, Nathaniel Dolan Apr 2011

On Parmenides’ Reality, Nathaniel Dolan

Undergraduate Student Symposium

The treatment being submitted here for the Farquhar College of Arts and Sciences Undergraduate Student Symposium began quite simply in the form of a journal entry submitted as one of the required elements of Dr. Toscano’s Introduction to Philosophy (PHIL 1010) in the 2010 fall term. The professor’s review and critique of that original work (which was comparably brief compared to this final edition) produced remarks from Dr. Toscano that motivated me to reevaluate my own interpretations of the proposition on Reality put forth by Parmenides of Elea in the fifth century BCE. Having studied philosophy as a personal interest …


More Than Just A Memory, Sebastian Acosta-Nijamkin Apr 2011

More Than Just A Memory, Sebastian Acosta-Nijamkin

Undergraduate Student Symposium

“More than just a memory” is a film about love and friendship. Ethan is confronted with a tough decision: whether to tell the girl he loves how he really feels, or whether to accept the fact that she loves someone else and that Ethan will only be a friend in her eyes. Throughout the film, Ethan is driving in a car, and flashbacks of the night where he chose to be just a friend keep entering his mind. That night he made a choice -- a choice that would change his life forever. The film is directed by Sebastian Acosta-Nijamkin.


Transcriptome Analysis Of Lagenidium Giganteum, Jennifer L. Grant Apr 2011

Transcriptome Analysis Of Lagenidium Giganteum, Jennifer L. Grant

Undergraduate Student Symposium

Mosquitoes are carriers of numerous diseases for instance, malaria and west-Nile virus. Lagenidium giganteum is a parasitic organism during larval stage that infects and kills mosquitoes. In time, this could be proven to be useful in bioengineering to create an environmentally safe insecticide. Molecular research was performed in order to determine the imperative genes in Lagenidium giganteum that hinder the development in mosquito larvae. A culture of Lagenidium giganteum was used to extract RNA and initiate a transcriptome analysis. Large scale sequencing led to the annotation of 20,000 transcripts. PCR amplification was performed using a Qiagen PCR kit in order …


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 Regression Study Of The Relation Between Rocks And Fish Assemblages, Kaitlyn Brucker Apr 2011

A Regression Study Of The Relation Between Rocks And Fish Assemblages, Kaitlyn Brucker

Undergraduate Student Symposium

The objective of this study is to see if the amount of rock in a given transect is related to the fish that inhabited the area. A regression analysis is conducted to find the relation between the two variables, rocks and fish. Besides finding the model, the analysis includes the confidence interval for the coefficient s, residual plots, predicted intervals of the number of fish for selected values of the amount of the rock, and identifying outliers and influential points by looking at various statistics, such as RESIDUAL, STUDENTIZED RESIDUALS, COVRATIO, and DFFITS.

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 …


Adhesion Of Transferrin To Tisifilcon A Contact Lenses, Darshan Solanki, Stephanie Brinon Apr 2011

Adhesion Of Transferrin To Tisifilcon A Contact Lenses, Darshan Solanki, Stephanie Brinon

Undergraduate Student Symposium

Tear proteins are known to deposit differently on contact lenses of different materials, causing lens wearer comfort to be compromised. We examined the adhesion of transferrin to contact lenses made of tisifilcon A, a rigid gas-permeable silicone hydrogel (FDA Group III). Lenses were incubated 2.0 mg/ml solutions of human holo-transferrin for 1, 2, 3, and 4 days, and protein adhesion was determined by bicinchoninic acid assay. Transferrin adhesion increased from day 0 to day 3 and then dropped after days 4 and 5. This pattern resembled transferrin adhesion to lenses made of polymacon (FDA Group I), alphafilcon (FDA Group …


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 Apr 2011

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 …

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg Apr 2011

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg

Undergraduate Student Symposium

Sugar substitutes are marketed as being healthier than sucrose (table sugar). Within this experiment, information about how table sugar and three different sugar substitutes, Splenda (sucralose-based), Truvia (stevia-based), and Equal (aspartame-based), affect gene expression in yeast was examined. Since the genomes of yeast and humans are approximately 30% similar, the specific genes selected for analysis in yeast overlapped with genes that are expressed in humans. Thus, Saccharomyces cerevisiae (Baker’s yeast) was used as a model eukaryotic organism in order to examine the effects of sugar substitute exposure on gene expression. The yeast was grown under four different conditions: 1) A …

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 …

Synthesis Of Porous Organic Materials For Gas Storage Media, Reena Parikh

Undergraduate Student Symposium

The purpose of this research is to help synthesize porous organic materials as possible gas storage media. Moreover, experimentation and chemical reactions will assist in finding and producing products that will be porous. Their porous nature will enable them to hold a certain volume of gas or act as agents for drug delivery. Earlier research involved a reaction to place an extra ring on the compound NBAIICuOAc. This molecule has two benzene rings, of which have shown to hold a trace amount of methane gas after DMF and H2O have been removed from it. It has been hypothesized …


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 …
