INTRODUCTION AND METHODS Dynamic fluorescence quenching is a technique that may overcome some of the limitations associated with measurement of tissue partial oxygen tension (PO2). We compared this technique with a polarographic Eppendorf needle electrode method using a saline tonometer in which the PO2 could be controlled. We also tested the fluorescence(More)
The effects of adding fly ash to soil were evaluated in some common soil tests. When fly ash and soil are mixed and compacted immediately, the fly ash causes the mixture to have a higher dry unit weight, by filling in voids with ash particles. As a soil-fly ash mixture sits uncompacted, flocculation and agglomeration of the soil particles occurs as the fly(More)
