The pore sizes of MCM-41 and KIT-1 mesoporous materials could be controlled by the addition of 1,3,5-trimethylbenzene as a complementary chemical or the use of templates with different chain lengths such as ?? and ??. The synthesized mesoporous materials are characterized from X-ray diffraction patterns and N₂adsorption isotherms. With the addition of 1,3,5,-trimethylbenzene, the pore size of synthesized, mesoporous material increased, while the pore size distribution became broad. On the other hand, the mesoporous material synthesized using a template with a larger carbon chain such as ?? showed larger pore size with a narrow distribution.

The conventional computer has the excellent performances in data management and numerical calculation, but it has reached limitation in a field of parallel processing such as image and speech processing. Neural networks have been studied in order to overcome this limitation. Recently, neural processor has been developed up to the level of the chip. Neural networks are composed of the connection of unit cells which have functions of multiplication, addition and transformation. In this paper a neural network is designed in digital method which easily adjusts weights and fabricated with an EPLD device.

The purpose of the research is to study the prediction of heat transfer on flat heat pipe applid to solar energy collector by the numerical study. Numerical analysis was performed by finite element method for the prediction of heat transfer on flat transfer on flat heat pipe. A comparison between the experimental and the numerical results show qualitatively agreement and it was able to predict the performence of flat heat pipe collector. The Biot number, (h_(ev)l)/Ks in order to know the effect of heat transfer on flat heat pipe was show to decrease by increas of heat transfer coefficient in vapor region, and with higher conductivity of container, Ks.

A numerical and experimental study have been performed on the heat transfer in rectangular solid owned heat source. The effects of thermal conductivity k, heat transfer coefficient h, temperature of surrounding fluid To and the rate of heat flow Q were studied numerically by F. E. M. The experiment were studied by given rectangular solid. The results of F. E. M. and experimental are as follows. 1) The F. E. M. to calculate the temperature distribution in rectangular solid showed good agreement with experimental. 2) Thermal conductivity influenced strongly temperature distribution in the solid but heat transfer cofficient influenced only surface. 3) Temperature gradient in the solid was unconcerned by temperature of surrounding fluid and rate of heat flow but temperature in the solid changed at a fixed rate.

Carbon monoxide is generated from the incomplete combustion of carbon-containing materials. Carbon monoxide cause muscle necrosis leading to myoglobinuria and acute renal failure. The hyperbaric oxygen exposure is increased production of active free radicals. Free radicals which promoted peroxidation of unsaturated fatty acids may destroy essential cellular components and itself cytotoxic materials. Superoxide dismutase, one of the protective mechanisms against tissue damage, catalyzed the dismutation of superoxide anion to less toxic product. The author performs the present study to investigate on Mn-SOD and Cu, Zn-SOD immunoreactivities in kidney and heart carbon monoxide (CO) and hyperbaric oxygen (HBO) exposure. The animals were divided CO exposure group, air release after CO exposure group, HBO exposure group and, CO and HBO exposure group. The specimen were sectioned in 16㎛ with cryostate. The Mn-SOD and CuZn-SOD immunohistochemistry was performed in renal corpuscle, proximal and distal convoluted tubules of kidney and, in sarcoplasm and sarcolemma of heart muscle. The results obtained were as follows: 1. The immunoreactivity of Mn-SOD were increased in renal corpuscles and distal convoluted tubules, were similar to control group in proximal convoluted tubules. 2. The immunoreactivity of Cu, Zn-SOD were increased than that of control group in renal corpuscles and distal convoluted tubules, were same that of the control group in proximal convouted tubules. 3. The immunoreactivity of Mn-SOD were increased at all experimental group of sarcoplasms of heart muscle. 4. The immunoreactivity of Cu,Zn-SOD were increased than that of control group in sarcolemma of heart muscle. These results suggest that the immunoreactivity of SOD after CO or HBO exposure is greatly increased in kidney and heart.
