Student-centered and project-based collaborative learning strategy is highly emphasized in education, especially in STEM fields. Despite its many advantages in supporting learning and professional growth, negative factors that influence collaboration cannot be ignored. By far one of the most frequently mentioned factors is unequal contribution from teammates, which leads to frustrations in the process and […]
CSIV-04: 2D Ratcheting of Cold Atoms
Brownian motion was originally discovered as a biological phenomenon, when botanist Robert Brown observed rapid oscillatory motions of pollen grains in water under a microscope. This phenomenon was originally thought only to be present in living organisms, but further research showed that Brownian motion was observed in all physical systems, from particles of smoke to […]
CSIV-05: Role of Hypoxia on Chick Retinal Pigment Epithelium Reprogramming
The retina is one of the most important tissues since an injury to the retina can lead to irreparable visual loss. Therefore, studying the process of retinal regeneration is important for understanding how the retina can be healed after an injury. The embryonic chick has been identified as a model for retinal regeneration, as until […]
B35: Sedimentation Trends in Acton Lake
Acton Lake is a reservoir in Hueston Woods State Park that was created in 1956 by the damming of Four-Mile Creek. Early on, high levels of erosion and agricultural runoff contributed to high sedimentation rates. In 1992, the USDA began encouraging farmers in the Acton Lake watershed to adopt conservation tillage. The goal of this […]
CSI-02: The Effect of Ambient Noise Within a Vehicle on the Audibility of Safety Sirens
Reaction time while driving is crucial, and even one second can be the difference between life and death. As safety vehicles use sirens to alert civilians, the ability of the public to respond appropriately to such signals will depend on the audibility of sirens. This project aims to evaluate the impacts of sound damping from […]
A04: Differential Expression of Cysteine Proteases in Carica papaya
Papain-Like Cysteine Proteases (PLCPs) are a family of protein degrading enzymes with similar structures and functions, thirty-three of which are found in Carica papaya (C. papaya). Papain, the namesake of the enzyme family, is extensively used in industry and harvested from the latex of un-ripened C. papaya fruits. In addition to its industrial importance, papain, […]
A05: Distinguishing Species-Specific Pollen Differences in Genus Vasconcellea of the Papaya Family
Palynology, or the study of pollen/spores is a functional field that informs physical and evolutionary relationships of plants. This field helps augment historical, archeological, and environmental studies dealing with plant identification based on pollen morphology and can infer global plant diversity and evolutionary patterns in pollen and pollen/pollinator interactions. Previous work on pollen morphology in […]
A08: Non-maternal Adult- And Subadult-Infant Interactions in Wild Woolly Monkeys
BackgroundIn many primates, males and/or non-lactating females are attracted to young infants and some may provide nonparental care (alloparenting) or engage in other forms of infant handling (holding, carrying, playing, and inspecting). The way in which these interactions play out may differ depending on varied factors (e.g. relatedness to the infant, dominance relationships, group dynamics, […]
A13: The Effect of Education Level on HPV Immunization Status in the United States: A Cross-sectional Study
The Human Papillomavirus (HPV) vaccine effectively prevents up to 90% of HPV related cancers, including most cervical, oropharyngeal, anal, penile, vaginal, and vulvar cancers in the United States. Despite the proven efficacy of the HPV vaccine, only around 50% of eligible youth have been vaccinated. Multiple previous studies found that parental education achievement was an […]
A15: Depression and Sleep Disorders in Adults Aged 20+: A Cross-Sectional Study
Sleep disorders are the second most common cause of depression in the United States. When prolonged, sleep disorders not only cause psychiatric disorders, but also hypertension, heart attacks and strokes. Currently, there are no studies confirming the relationship between sleep disorders and depression using the National Health and Nutrition Examination Survey (NHANES) data from 2017-2018. […]
