Using Dialogue to Engage Agricultural Audiences in Cooperative Learning About Climate Change: A Strategy with Broad Implications

Dialogue with stakeholders has been recognized as an effective educational strategy for addressing complex topics such as climate change. We report here on the Carbon, Energy, and Climate fishbowl discussion series developed by Michigan State University Extension to assist the state\u27s agricultural community in understanding and adapting to the changing climate. Facilitated dialogue reduced barriers to communication and promoted cooperative learning for target audiences and the project team, generating useful information on the current status of climate change adaptation within Michigan\u27s agriculture sector and revealing needs to be addressed by future Extension programming. Using a dialogue-based approach such as the one we describe can highlight challenges and opportunities Extension faces in addressing various complex issues with diverse audiences

Measurement of Both Gas and Particle Velocity in Turbulent Two-Phase Flow

A laser-Doppler anemometer was used to measure the velocity of both the gas and particles in a turbulent two-phase flow for conditions when the distribution of the velocities of the two phases overlaps. The velocities from the two phases are separated by comparing the Doppler amplitude to the pedestal amplitude. Results of the measure of the gas-particle flow downstream of a nozzle mounted in a circular pipe are presented

Room temperature high frequency transport of Dirac fermions in epitaxially grown Sb_2Te_3 based topological insulators

We report on the observation of photogalvanic effects in epitaxially grown Sb_2Te_3 three-dimensional (3D) topological insulators (TI). We show that asymmetric scattering of Dirac electrons driven back and forth by the terahertz electric field results in a dc electric current. Due to the "symmetry filtration" the dc current is generated in the surface electrons only and provides an opto-electronic access to probe the electric transport in TI, surface domains orientation and details of electron scattering even in 3D TI at room temperature where conventional surface electron transport is usually hindered by the high carrier density in the bulk
