  • 4 Theatres... 

    Ruhland III, James Randolph (Virginia Tech, 2006-04-17)
    Abstract <p> This Project concludes in a folio of drawings. The object of study is a renewal of Blacksburgâ s old Town Hall on Church Street. The proposed new program for the existing structure is a studio theatre, ...
  • 4 urban houses 

    Scott, Keith A (Virginia Tech, 1994)
  • 4 walls + 

    Ebert, Doreen (Virginia Tech, 2000-05-02)
    A higher level of complexity is possible by combining more than one idea as long as the order of the elements is readable in each built condition. Order is possible at any level of complexity. The more complex the greater ...
  • [4+1] cyclopentene annulation in the total synthesis of pentalenene type sesquiterpenes 

    Natchus, Michael George (Virginia Polytechnic Institute and State University, 1987)
  • 45 King: A Story of the Southern Home 

    Deluca, Paul Matthew Webb (Virginia Tech, 2014-07-15)
    The house at 45 King St. in Charleston, South Carolina is more than a home. It is a story of the home. A story told through history, through a vision exhibited in architectural drawings, and through the social heritage ...
  • A 4700-Year Record of Lake Evolution and Fire History for Laguna Limon, Dominican Republic 

    McVay, Jason Lyle (Virginia Tech, 2013-05-23)
    Fire is a primary driver of environmental change that can originate from natural or human ignition. Macroscopic charcoal (>125 "m) deposited into lake sediment is a record of a local fire event, whereas microscopic charcoal ...
