SIMULTANEOUS EVALUATION OF P-v-T, ISOBARIC SPECIFIC HEAT AND JOULE - THOMSON COEFFICIENT MEASUREMENTS

A method is given in this paper that enables the simultaneous evaluation of P-v-T, isobaric specific heat and Joule - Thomson coefficient (J. T. C) measurements. It gives the ideal gas isobaric specific heat function and a semi-explicit v = v(P, T) equation of state (E. O. S) as results. The results for the vapor phase of R227 are presented also

REMARKS ON SOLUTION METHODS OF VIRIAL-TYPE EQUATIONS OF STATE

The paper gives an unconditionally successful and rapidly converging procedure to solve virial-type EOS for the unknown vapor and liquid densities, and presents methods to improve the convergence of the vapor-liquid equilibrium ratios and of the vapor-liquid rate

Brain macrophages in human cortical contusions as indicator of survival period

The aim of this study was to establish a morphologic time scheme with which cases of cerebral contusion with unknown survival periods can be dated. Our study of 275 cases was limited to qualitative and quantitative changes in macrophages. The appearance of macrophages and their distribution as well as their content of neutral fat, esterified cholesterol, erythrocytes, siderin, hematoidin, and ceroid were correlated with the survival period. For each cytologic criterium, the observation period, distribution-free limits of tolerance, and relative frequency of identification in different survival periods were determined, and the limits of confidence calculated. The findings permit the dating of trauma in cases with unknown survival periods. Moreover, the probability of this dating was calculated
