    Notes: Abstract The fatigue crack growth behaviour of dissimilar bonded materials was studied using explosively bonded naval brass clad steel plate and roll bonded nickel clad and naval brass clad steel plates. When the residual stresses produced during manufacturing processes were small, the fatigue crack growth rates showed a good correlation with the true ΔK-values evaluated for the dissimilar bonded materials; apparent ΔK-values, determined on uniform material, failed to be a correlating variable. The residual stresses strongly affected the fatigue crack growth rate of the dissimilar materials. Some microscopic and fractographic observations were made on the fatigue-fractured dissimilar materials.

    Notes: Abstract The confluence of the right and left hepatic ducts at the hepatic hilum frequently shows normal anatomic variations. Choledochal cysts (CC) are also accompanied by similar variations, and devices for free drainage of bile are occasionally required in biliary reconstruction. We present a CC that had an aberrant posterior branch of the right hepatic duct draining into the distal common hepatic duct. A capacious hepaticoduodenostomy at the hilum was performed after joining the hilar and aberrant ducts.

    Notes: Abstract Esophageal hiatal hernias (EHH) are probably caused by congenital, traumatic, or iatrogenic factors, although the etiology remains unknown. EHHs may develop after abdominal wall closure for omphalocele or gastroschisis due to the increased intra-abdominal pressure, however, there have been few reports in the literature. We present a case of EHH developing after abdominal wall closure.

    Notes: Abstract We investigated the possible involvement of apoptosis in the increased germ-cell degeneration in undescended testes (UDT). Experimental unilateral cryptorchidism was induced in 21-day-old rats, and both testes were removed for in-situ TUNEL staining of apoptotic cells at 1, 3, 7, 10, and 14 days postoperation. A gradual increase in the incidence of apoptosis was seen at 21–28 days of age in the control testes, followed by a decrease thereafter. After 10 days postoperation, the weight of the UDT was significantly lower than that of the contralateral descended testis (CDT) and the controls. However, the weight of scrotal testes in each group was similar. UDTs demonstrated a markedly increased incidence of apoptosis. By 7 days postoperation, the percentage of seminiferous tubules containing apoptotic germ cells significantly increased in UDTs compared with that in CDTs and controls (P 〈 0.001). Moreover, there was a significant difference in the percentage of seminiferous tubules containing apoptotic germ cells between CDTs and controls (P 〈 0.01). In addition, an increased incidence of seminiferous tubules containing 8–10 and 〉10 apoptotic germ cells from 7, 10, and 14 days postoperation in UDTs was detected. In-situ TUNEL analysis demonstrated spermatocytes to be the main type of germ cells affected in all groups. These findings suggest that spermatogenesis decreases not only in the␣UDT, but also in the CDT, and that the germ-cell degeneration in cryptorchidism took the form of apoptosis.

    Notes: A surface strain measurement approach to understanding of delamination processes of thermal barrier coatings (TBCs) under heat cycle conditions was described in this paper. Heat cycle tests between the high temperature ranged from 1473K to 1073K and the relatively low temperature (573K) was carried out on thermal barrier coated type 304 stainless steel specimens. 8mass%Y〈sub〉〈/sub〉2O〈sub〉〈/sub〉3-ZrO〈sub〉〈/sub〉2 and Al〈sub〉〈/sub〉2O〈sub〉〈/sub〉3 coatings were used for the TBCs. The surface strain behavior during the heat cycle test was measured using a laser speckle strain/displacement gauge (SSDG). It was found that the thermal expansion of a substrate was almost reflected on a surface strain if a delamination wasn't initiated, while the value of a surface strain decreased to the value of the thermal expansion of a ceramics-coating if the delamination of the ceramics-coating was initiated. The state of a subsurface delamination was able to be nondestructively inferred by the surface strain behavior. The delamination life of a ceramics-coating in the specimen with a low-pressure-plasma-sprayed (LPPS)bond-coating was found to be longer than that with an atmospheric-plasma-sprayed (APS) bond-coating. The large roughness of a bond-coating was also found to be effective in improving the delamination life of a ceramics-coating owing to the restriction of a crack propagation parallel to the interface between the ceramics-coating and the bond-coating

    Notes: Abstract We have carried out systematic surveys for small bright-rimmed clouds associated with IRAS point sources in/around HII regions. They are candidate sites for star formation due to radiation-driven implosion.
