The Road Environment and Urban Bicycling: Psychophysiological and Behavioral Responses and their Implications for Transportation Planning

  • Principal Investigator Dillon Fitch-Polse, Ph.D.
  • University of California, Davis
The three-part research study focuses specifically on the relationship between the road environment and bicycling behaviors. Results demonstrate that large scale changes to road environments may be needed to influence bicycling perceptions, attitudes, and behavior.

Understanding and Advancing THF Co-Solvent Enhanced Lignocellulosic Fractionation (CELF) Pretreatment when Integrated with Enzymatic Hydrolysis and Fermentation

  • Principal Investigator Abhishek S. Patri
  • University of California, Riverside
Co-solvent Enhanced Lignocellulosic Fractionation (CELF) has been developed as an advanced pretreatment technology to achieve high sugar yields from biomass at low enzyme loadings. In this thesis, the reasons behind increased digestibility of Alamo switchgrass after CELF were investigated in comparison to research benchmark dilute sulfuric acid (DSA) pretreatment.
