Computer Modelling Of The Interaction Between Cerme-8 J Domain And Cehsp70-1, Grace Thornhill, Cole Easley
Undergraduate Research Conference
Abstract: Rme-81 is a J domain-containing plasma membrane protein that is required for endocytosis in various cells2. The J domain is a characteristic structural motif found mainly in heat shock protein 40 (Hsp40 or DnaJ) and other proteins such as Rme-83. Within the J domain is a tripeptide, the HPD motif, that is required by the J-domain protein to interact with and stimulate the ATPase activity of Hsp70, a major cellular chaperone4. The Rme-8 protein in C. elegans, CeRme-8, has not been identified with a particular Hsp70 partner. CeHsp70-1 is the only cytosolic Hsp70 in C. elegans, therefore, we hypothesize …

Bomb Calorimetry: A New Method Of Cec Determination, Trace Washburn
Bomb Calorimetry: A New Method Of Cec Determination, Trace Washburn
Undergraduate Research Conference
A new method of determining the cation exchange capacity (CEC) of clay minerals was examined. This method involved exchanging the smectite clay with organic cations and using bomb calorimetry to measure the energy of combustion of the material. Because the clay is noncombustible, the energy is completely dependent on the amount of organic present, which is dependent on the CEC of the clay. Two organic cations, tetrapentylammonium and octadecyltrimethylammonium , with similar size but much different shape were used. For clays with lower CECs, using the more symmetric ion yielded better accuracy (4.24%), while for clays with higher CEC, using …
