Notes: Abstract A new method was developed to determine simultaneously the thermal conductivity, thermal diffusivity, specific heat, and calorific intensity of the organ or tissue of a living body either in vivo or in vitro with a thin hot probe. By using the method, the thermophysical properties and calorific intensities of a human palm and in vivo liver and a kidney, heart, brain, and foreleg and hindleg muscles of an anesthetized canine were measured. It is concluded that there are no significant differences in the thermophysical properties of organ or tissue of a living body either in vivo or in vitro. The measured thermophysical properties are in good agreement with those reported in the literature.

Notes: The recently synthesized metal-encapsulated porphyrazine compound, [Sn(t-Bu)2]4-star-Ni(porphyrazine)-S8, shows very interesting structural and optical absorption features compared with other metal-centered porphyrazines, e.g., metal phthalocyanines (Pc). Using self-consistent-field local density theory, we studied the ground-state and excited-state electronic structure of this molecule and compared it with its metal phthalocyanine analog NiPc. The theoretical optical spectra including oscillator strengths are in good agreement with experimental absorption and show that the characteristic transitions at the so-called Soret band in NiPc are red-shifted in the new compound. © 1994 John Wiley & Sons, Inc.
