An Analog Macroscopic Technique for Studying Molecular Hydrodynamic Processes in Dense Gases and Liquids Jerry Dahlberg1, Peter T. Tkacik1, Brigid Mullany1, Eric Fleischhauer1, Hossein Shahinian1, Farzad Azimi1, Jayesh Navare1, Spencer Owen1, Tucker Bisel1, Tony Martin1, Jodie Sholar1, Russell G. Keanini1 1Department of Mechanical Engineering, University of North Carolina at Charlotte An experimentally accessible analog method for studying molecular hydrodynamic processes in dense fluids is presented. The technique uses particle image velocimetry of vibrated, high-restitution grain piles and allows direct, macroscopic observation of dynamical processes known and predicted to exist in strongly interacting, high density gases and liquids.
Study of the DNA Damage Checkpoint using Xenopus Egg Extracts Jeremy Willis*1, Darla DeStephanis*1, Yogin Patel1, Vrushab Gowda1, Shan Yan1 1Department of Biology, University of North Carolina at Charlotte Xenopus egg extract is a useful model system to investigate the DNA damage checkpoint. This protocol is for the preparation of Xenopus egg extracts and DNA damage checkpoint inducing reagents. These techniques are adaptable to a variety of DNA damaging approaches in the study of the DNA damage checkpoint signaling.
