A Floral Assemblage Of The Upper Cretaceous El Gallo Formation, El Rosario, Baja California, Mexico, Reilly F. Hayes, Marisol Montellano-Ballesteros, Gerardo Álvarez-Reyes, René Hernandez-Rivera, David E. Fastovsky

Senior Honors Projects

Over the past eight months, I have collaborated with paleontologists from the Universidad Nactional Autónoma de México to formally describe plant fossils they uncovered in Baja California between their 2013 and 2016 field seasons. We report the first floral assemblage of the dinosaur-aged El Gallo Formation, Baja California, Mexico, a small (82-specimen) collection of plant fossils from fossil soils contained within the 75.84 +/- 0.05 to 74.55 +/- 0.09 million-year-old El Disecado Member of the unit. A compound fruit belonging to the genus Operculifructus, previously reported from the 3.40 to 1.08 million year younger Cerro del Pueblo Formation, Coahuila, …

Solving A Rubik’S Cube: An Analysis Of Problem Solving Strategies, Nicole Kerrigan

Senior Honors Projects

Stumbling upon a difficult problem to solve is inevitable. A difficult problem is defined as a problem in which the solution is not easily discovered for a typical person. These problems can range from real-life situations, such as quitting an addiction or finding a cure for cancer, to recreational puzzles such as a game of chess or a Rubik’s Cube. Due to their complexity, and in some cases lack of information on the subject, it is easy to get frustrated and not try when one encounters such a problem. For this reason, it is imperative to have a skill set …

Do Halogenated Natural Products Bioaccumulate In Narragansett Bay?, Christine Gardiner, Anna Robuck, Rainer Lohmann

Senior Honors Projects

In recent decades, a new family of chemical compounds has begun to garner research attention—halogenated natural products, or HNPs. These chemicals are produced by algae, bacteria, worms, and sponges, and many are structurally similar to harmful manmade compounds, such as polychlorinated diphenyls (PCBs), or brominated flame retardants (PBDEs), which are known to cause cancer, reproduction issues, endocrine disruption, and death. While HNPs are produced naturally, they are still considered pollutants because of their bioaccumulative behavior and apparent toxicity.

Currently, there is limited research on their presence and effects, with a few studies from Europe and the Pacific highlighting their importance …

Rate Acceleration Of Organocatalytic Ring-Opening Polymerization Rough The Application Of Bis- And Tris- ( Io)Urea H- Bond Donors, Samuel S. Spink

Senior Honors Projects

Well-defined and functionalized polymers have a wide variety of applications in biomedical studies. Advancements in the fields of drug delivery, microelectronics, and medical imaging, among other applications, are predicated upon the development of methods for the synthesis of precision polymers. Organocatalytic ring-opening polymerization (ROP) of cyclic monomers is an effective route to the production of polymeric materials, namely polyesters and polycarbonates, whose biodegradable properties make them a viable option in biomedical research. Arguably, H-bond mediated catalysts are among the most selective catalysts for ROP, giving rise to highly functionalized polycarbonates, well-controlled polymerizations, and other custom tailored applications. With respect to …

English Language Learners In The Mathematics Classroom, Julia Mccormick

Senior Honors Projects

Mathematics is often considered a universal language. Most of us have heard this statement from a math teacher at some point throughout our academic careers. However, for students moving to the United States from another country with minimal fluency in English, this is clearly not the case. They may walk into math class, a subject area in which they may have excelled in their native country, and see the words “polynomial”, “coefficient”, and “differentiate” on the board. Regardless of their experiences in their native language, there are disconnects and cultural differences between languages and skills emphasized that prevents mathematics from …

Alternative Process Photography: Beyond Digital And Film, Laura Michaud

Senior Honors Projects

The first permanent photograph was created in 1826 by Joseph Nicéphore Niépce. To do this, he coated light sensitive chemicals on a metal plate and exposed it in a camera obscura (a box with a small hole; a “pinhole camera”). Once the plate was properly exposed to light, he used more chemicals to stop the plate from being light sensitive and make the image permanent on the plate. Throughout the years, many photographers and chemists used many different chemicals, materials, and procedures to create permanent and beautiful images (i.e. Daguerreotypes, Calotypes, Heliographs, etc). With each new process, the previous processes …
