Calcium chromite, CaCr204, was prepared and its purity and stoichiometry were ascertained by chemical analysis and X-ray diffraction methods. The thermal diffusivity, specific heat capacity and thermal conductivity of calcium chromite were measured by Laser Flash method using an Ulvac-Sinku Riko TC 3000 series instrument in the temperature range of 298 to 1100 K. The heat capacity data were utilised to calculate the thermodynamic parameters--enthalpy increments, entropy increments and free energy increments--in the above temperature range.

Pulmonary alveolar proteinosis is a rare type of interstitial lung disease characterised by diffuse involvement and filling of distal air spaces by the amorphous, periodic-acid-schiff positive lipoproteinaceous material. Whole lung lavage is presently the standard mode of management of such cases. A 33-year-old male presented to our centre with cough and breathlessness on exertion. On evaluation he was found to have PAP. He underwent whole lung lavage (WLL) under general anaesthesia using one lung ventilation. We describe the anaesthetic consideration and the challenges faced in such a procedure.
