The increasing population of south Florida is creating a need for greater waste-water disposal capacity. The people of Florida are dependent on ground water for drinking, irrigation, and other uses. The emphasis on preservation of surface-water quali

Differential scanning calorimetry (DSC) and thermal optical analysis (TOA) were applied as part of a series of characterization methods to solid chemically crosslinked polyethylene insulation. The DSC was used to study the melting and recrystallizati

Binary mixtures of liquid crystals have been studied for a variety of reasons. For many applications a mixture will extend the mesophase temperature region particularly to cover ambient temperatures. Mixtures are sometimes used to investigate the exi

Use of a thermomechanical analyzer, TMA, affords a rapid, precise method for determining linear expansion coefficients and linear expansivities of cross-linked polymeric insulation material. Completed cable samples were dissassembled and insulation s
