Abstract

An endurance test for a printed circuit board to ionic migration was carried out for 2000 h in a chamber controlled at 85 [degrees] C and 85%RH. The capacitance C and tan [Delta] between the conductors on the board were measured to find their correlation with ionic migration in the board. The measurement frequency of C and tan [Delta] ranged from 1 to 1000 Hz. The configuration of the test circuit was designed according to IPC-SM-840. The material of the insulating board was fiberglass-reinforced epoxy resin. The distance between the Cu conductors was 0.165 mm, and 70 V dc was applied continuously. In the low frequency region ([is less than] 30 Hz), C and tan [Delta] gradually increase after ~800 h voltage application. During the gradual increase, steeply transient increases in C and tan [Delta] are detected at about the same time when a deposit was seen to have formed on the board between the conductors, although no significant decrease in insulating resistance between the conductors is observed. It was confirmed that the deposit could be detected early from the steep increases in C and tan [Delta] in the low frequency region. In the high frequency region ([is greater than] 30 Hz), on the other hand, gradual slight increases are observed from ~1100 h after voltage application, but no steep increases. The dependence of C and tan [Delta] on frequency at the measurement is due to the low mobility of Cu ions in the water film on the insulating board.

Abstract

Fucoxanthin has a unique structure including an unusual allenic bond and 5, 6-monoepoxide in its molecule. We found that abdominal white adipose tissue (WAT) weights of rats and mice fed fucoxanthin were significantly lower than those fed a control diet. The daily intake of fucoxanthin in mice also caused a significant reductions of body weight. Clear signals of uncoupling protein 1 (UCP1) and its mRNA were detected by Western and Northern blot analyses in abdominal WAT in mice fed fucoxanthin, although there is little expression of UCP1 in WAT in mice fed a control diet. UCP1 expression in WAT by fucoxanthin intake leads to oxidation of fatty acids and heat production in WAT mitochondria. Substrate oxidation can directly reduce WAT in animals. Fucoxanthin intake also significantly reduced blood glucose and plasma insulin. Furthermore, feeding fucoxanthin significantly increased the level of hepatic docosahexaenoic acid (DHA), a most important n-3 functional polyunsaturated fatty acid in biological systems. These multi-functionalities of fucoxanthin indicate that it is an important bioactive carotenoid that is beneficial for the prevention of the metabolicsyndrome. [ABSTRACT FROM AUTHOR]
