Combination of Microwave Hyperthermia and Radiation Therapy is effective for treatment of tumor. After increasing the temperature the tumor becomes more sensitive to radiation dose. In this paper, the Invasive and Non-invasive microwave antennas were designed and applied on different tissues including malignant tumor, and respective Specific Absorption rate (SAR) patterns and temperature rises were investigated. For invasive antenna, coaxial-slot antennas was investigated and for non-invasive antenna, ...

Abstract In the nuclear power plants, the reservation of safety and before-it-happens prevention of a trouble are important themes. Moreover, in connection with the life extension of a plant, life-expectancy diagnosis has also been an important subject. Although it is technology required in order that a non-destructive test may secure the safety of a power generation plant, Ultrasonic Testing (UT) is applied. However, generally the welding of stainl ess steel piping used widely in the PWR type nuclear powe...

Weld pass sequence generally affects residual stress profiles. In this study, the profiles of a multi pass bead on plate specimen were experimentally and analytically examined. Material used in this study was the low alloy steel SQV2A (JIS G 3120). Phase transformation usually occurs around welded area in SQV2A and also affects the profiles. Five pass bead on plate specimen was fabricated. Residual stress profiles of the specimen were measured by using the strain relief method. Longitudinal residual st...
