Synthetic Amphiphiles As Antibiotic Potentiators, Helena Spikes

Dissertations

Antibiotic resistance has become a massive threat to modern medicine. Bacteria acquire resistance either through genetic mutations or mobile genetic elements, such as plasmids. The growing resistance crisis is exacerbated by over-prescription of antibiotics and improper use. As antimicrobial resistance becomes more widespread, superbugs (bacteria resistant to more than one class of drug) have evolved. Since few new drugs reach clinical trials and even fewer are approved by the FDA, we must find a way to make existing drugs more potent. One technique to accomplish this is by using combination therapy. By administering two or more drugs at a time, …

The Effects Of Segmenting Worksheets And Behavior Specific Praise On Independent Seatwork With Elementary Students, Lauren Peak

Dissertations

While the education system has seen many changes over the years due to COVID-19, one constant is that students must complete independent seatwork at certain times throughout the day. As teachers accommodate the many students in their classroom, an intervention that could increase students’ amount of academic production when doing independent seatwork would be mutually beneficial. For students, the increased contact with learning opportunities would provide the students means to increase fluency for that skill. Examining the effects of segmented and whole worksheets on production would, therefore, create additional learning opportunities.

This study sought to assess the effectiveness of the …

Cell Size Control Mechanisms In The Multiple Fission Cell Cycle Of Chlamydomonas, Dianyi Liu

Dissertations

Size homeostasis is achieved by a balance between cell growth and cell division, but the underlying mechanisms are yet fully understood. Green alga Chlamydomonas reinhardtii (Chlamydomonas) is a unique model for size control. Instead of the canonical binary fission cell cycle, Chlamydomonas uses a multiple fission cell cycle where a prolonged G1 phase is followed by rapid alternative n rounds of S/M (DNA synthesis and mitosis) cycles to produce 2ⁿ daughter cells. Two size checkpoints show size-dependence: the Commitment checkpoint governs a minimum size for a cell to divide at least once, and the S/M checkpoint governs the division …
