Fuel Adulteration Detection Using Open-Ended Coaxial Line And Circular Waveguide Techniques, Abdulrahman Alofi, Ahmed Shamseldin, Sharif Iqbal M. Sheikh, Hussein Attia

Faculty Publications

Fuel adulteration, the practice of blending lower-quality substances like kerosene with gasoline, poses significant challenges for ensuring fuel quality and safety. This study investigates two electromagnetic-based methods for detecting such adulteration: the open-ended coaxial line method and the circular waveguide method. The results reveal that the open-ended coaxial line technique is particularly effective in detecting kerosene contamination, identifying levels as low as 10% by measuring changes in the dielectric constant of the gasoline-kerosene mixture. Operating in the frequency range of 0.25–1.25 GHz, this method captures subtle changes in permittivity. In contrast, the circular waveguide method evaluates contamination by monitoring shifts …

The C-Terminal Regions Of Trak Proteins Contain Miro-Independent Mitochondrial Localization Domains, Lili Mitchell, Kathryn E. Reda, Hijab Fatima, Claudia E. Vasquez, Omar A. Quintero-Carmona

Biology Faculty Publications

Current models suggest that MIRO GTPases anchor cytoskeletal motors to the mitochondrial outer membrane (MOM). However, our previous findings indicate that the unconventional myosin, MYO19, interacts with MIRO weakly and that a MIRO-independent MOM-localizing domain interacts more tightly with the MOM. To test the hypothesis that other MIRO interactors may also have MIRO-independent MOM binding, we examined interactions between TRAK proteins (microtubule motor-mitochondria adaptor proteins) and the MOM via quantitative fluorescence microscopy and steady-state kinetic approaches. Using GFP-TRAK truncations expressed in MIRO1-2 double knockout mouse embryonic fibroblasts, we identified a MIRO-independent mitochondrial-binding domain in the C-terminus of TRAK1 and TRAK2, …
