    Notes: This paper discusses an algorithm for phase change front identification in continuous casting. The problem is formulated as an inverse geometry problem, and the solution procedure utilizes temperature measurements inside the solid phase and sensitivity coefficients. The proposed algorithms make use of the boundary element method, with cubic boundary elements and Bezier splines employed for modelling the interface between the solid and liquid phases. A case study of continuous casting of copper is solved to demonstrate the main features of the proposed algorithms.

    Description: 125I-labeled fibrinogen or fibrin monomer (FM) were infused into rabbits, and the radioactivity in the blood, certain organs, and urine was followed. In the FM rabbits, a progressive, relatively rapid loss of blood radioactivity occurred which was accompanied by radioactive deposits in the organs and the excretion of radioactivity in the urine. Extraction of radioactive material from homogenized organ tissues of FM-infused rabbits showed that most of it had the characteristics of stabilized fibrin. Administration of EACA did not change any of the measurements in the fibrinogen animals but increased the rate and extent of fibrin deposition in the FM animals. In animals made leukopenic with HN2, fibrin deposition was inhibited. The findings indicate that a major pathway of FM clearance from the blood involves fibrin formation and deposition with subsequent degradation and excretion. The reticuloendothelial system appeared to play a major role in FM clearance, since most of the fibrin deposits were found in the liver, and the highest concentration was in the spleen. A nonenzymatic mechanism of fibrin formation from soluble FM involving leukocytes is postulated.
