This work presents an experimental and analytical investigation of heat and mass transfer with condensation in a fibrous insulation slab, one side of which is exposed to high temperature and high humidity, and the other side bounded by a cold surface. The analysis carried out is based on a model in which condensation occurs on the cold surface and in the interior of the fibrous insulation, and condensate falls away under gravity. Predicted heat transfer coefficients agreed well with experimental data at atmospheric pressure and temperatures up to 100°C. It was also indicated by the analysis that the convective contribution is appreciable in higher pressure and temperature environments.

We have collected four cases of supergiant cerebral aneurysm, each greater than 6.0 cm in diameter. Two of these cases were saccular aneurysms of the anterior communicating artery and middle cerebral artery, of which the necks were clipped with resection of the aneurysms. Another patient had a fusiform aneurysm of the middle cerebral artery, which was resected accompanied by a reconstructive procedure of cerebral blood flow. The last patient had a fusiform aneurysm of the internal carotid artery. Following internal carotid artery occlusion surgery with superficial temporal artery-middle cerebral artery anastomosis, the aneurysm completely disappeared radiologically within several months.
