BACKGROUND/AIMS We have performed ileocolon interposition for reconstruction (IR) after total gastrectomy in order to reduce postoperative symptoms such as heartburn, reflux esophagitis and nutritional disturbance. After IR, however, the frequency of diarrhea increased in the postoperative period. We therefore investigated whether post-IR diarrhea could be(More)
This paper discusses side acoustic radiation in leaky surface acoustic wave (LSAW) resonators on rotated Y-cut lithium tantalite substrates. The mechanism behind side radiation, which causes a large insertion loss, is analyzed by using the scalar potential theory. This analysis reveals that side radiation occurs when the guiding condition is not satisfied,(More)
