    The effect of temperature, time and hydrogen ion concentration on the colorfastness of a household dye on selected cotton fabrics
    Green, Susan Elaine (Virginia Polytechnic Institute and State University, 1979)
    A liquid household dye and two fabrics, a cotton drill and a crease resistant cotton muslin, were used to pursue the following objectives: (1) to develop a dyeing procedure for improving the colorfastness of a household dye; (2) to evaluate the effects of temperature, time, and pH (hydrogen ion concentration) of the dyebath on the colorfastness properties of the household dye selected; (3) to evaluate the effects of after treatments of acetic acid and copper sulfate; and (4) to evaluate the dyed samples for colorfastness to light, washing, and crocking. Dye results were evaluated by the use of the Gray Scale for Color Change and the AATCC Chromatic Transference Scale. Colorfastness ratings were statistically analyzed. Major findings of the research included the following: 1. The cotton drill fabric had higher colorfastness ratings for lightfastness, washfastness, and dry crocking than did the crease resistant cotton muslin. For wet crocking, both fabrics had considerable color transference. 2. A dyebath temperature of 210°F produced significantly higher ratings for lightfastness and washfastness in both fabrics tested. 3. The aftertreatment of 1% copper sulfate solution resulted in significantly higher lightfastness ratings for both fabrics tested. 4. There was no significant difference in the dyeing times of 10 minutes and 30 minutes, although the time of 30 minutes produced slightly higher ratings.

    Sticks and stones: a Blue Ridge Mountain retreat
    Green, Susan Elaine (Virginia Polytechnic Institute and State University, 1988)
    Given a sloping wooded site in the Blue Ridge Mountains of North Carolina, the problem of the thesis project was to design a retreat that would fit the environment and the people that would inhabit it. It was a searching for the interdependence between the landscape and the building. Equally important was a search for a structure that would give architectural integrity to the house. The design process included a time of discovery and clarification of values and priorities. Two additional steps during the schematic design were processes architect Charles Moore referred to as"mapping" and"collecting''. These processes help to establish relationships between the inhabitants and things they recognize. Structural elements of post and beam construction gave a sense of order in the design layout and helped to organize the spaces within the form of the house. A system of equidistant columns formed by four wood posts also provided the physical linkage between the building and the site. Native field stone was used for the large piers that supported the columns as well as for the perimeter walls of the living room structure. The inner landscape of the house, the pathways, the rooms and the machines within them, developed from the basic idea that the building would grow from a central axis or “spine” that originated from the outside at the street's edge, extended across the site,and moved into the building to become the main artery of the structure as well as the connection between outside and inside.
