EVALUATION OF INITIAL DEFECT FORMATION CONDITIONS IN WATER-BASED COATINGS APPLIED TO ONE-COMPONENT MODIFIED SILICONE SEALANTS

Masayuki TSUKAGOSHI, Yusuke Kikuchi, Hiroyuki Miyauchi

This study investigates initial cracking in water-based coatings applied over moisture-curing one-component sealants. Under low-temperature conditions, slower sealant curing and coating drying led to water infiltration into the sealant. Curing progressed from the interface between the sealant and the coating, causing shrinkage …

Abdominal nonfunctional paraganglioma in which succinate dehydrogenase subunit B (SDHB) immunostaining was performed: a case report

Takazo Tanaka, Akira Joraku, Sayuri Ishibashi, Keisuke Endo et autres

BACKGROUND: Abdominal nonfunctional paraganglioma is rare. Malignant potential of paraganglioma is assessed by Grading of Adrenal Pheochromocytoma and Paraganglioma score and genetic testing, but genetic testing is not common. We present a case of abdominal nonfunctional paraganglioma whose malignant potential was assessed …

Repetitive Partial Discharge Phenomena on Electrical Motor Coil Windings Under High-Repetition Nanosecond Pulsed Voltages Driven by SiC MOSFET Inverter

Yusuke Kikuchi, Jun Matsusue, Fuma Yamada, Takafumi Okuda et autres

This paper presents new findings on partial discharge (PD) phenomena under high-repetition nanosecond pulsed voltages, essential for the insulation design of electrical motors fed by silicon carbide (SiC) inverters with high-switching frequencies. Here, a twisted pair sample simulating the turn-to-turn insulation of …
