    Notes: Abstract —We classified tsunamigenic earthquakes in subduction zones into three types earth quakes at the plate interface (typical interplate events), earthquakes at the outer rise, within the subducting slab or overlying crust (intraplate events), and "tsunami earthquakes" that generate considerably larger tsunamis than expected from seismic waves. The depth range of a typical interplate earthquake source is 10–40km, controlled by temperature and other geological parameters. The slip distribution varies both with depth and along-strike. Recent examples show very different temporal change of slip distribution in the Aleutians and the Japan trench. The tsunamigenic coseismic slip of the 1957 Aleutian earthquake was concentrated on an asperity located in the western half of an aftershock zone 1200km long. This asperity ruptured again in the 1986 Andreanof Islands and 1996 Delarof Islands earthquakes. By contrast, the source of the 1994 Sanriku-oki earthquake corresponds to the low slip region of the previous interplate event, the 1968 Tokachi-oki earthquake. Tsunamis from intraplate earthquakes within the subducting slab can be at least as large as those from interplate earthquakes; tsunami hazard assessments must include such events. Similarity in macroseismic data from two southern Kuril earthquakes illustrates difficulty in distinguishing interplate and slab events on the basis of historical data such as felt reports and tsunami heights. Most moment release of tsunami earthquakes occurs in a narrow region near the trench, and the concentrated slip is responsible for the large tsunami. Numerical modeling of the 1996 Peru earthquake confirms this model, which has been proposed for other tsunami earthquakes, including 1896 Sanriku, 1946 Aleutian and 1992 Nicaragua.

    Asperity Distribution of the 1952 Great Kamchatka Earthquake and its Relation to Future Earthquake Potential in Kamchatka (1999)

    Notes: Abstract —The 1952 Kamchatka earthquake is among the largest earthquakes of this century, with an estimated magnitude of M w = 9.0. We inverted tide gauge records from Japan, North America, the Aleutians, and Hawaii for the asperity distribution. The results show two areas of high slip. The average slip is over 3 m, giving a seismic moment estimate of 155×1020Nm, or M w = 8.8. The 20th century seismicity of the 1952 rupture zone shows a strong correlation to the asperity distribution, which suggests that the large earthquakes (M 〉 7) are controlled by the locations of the asperities and that future large earthquakes will also recur in the asperity regions.

    Edge wave and non-trapped modes of the 25 april 1992 Cape Mendocino tsunami (1995)

    Notes: Abstract The 25 April 1992 Cape Mendocino earthquake generated a tsunami characterized by both coastal trapped edge wave and non-trapped tsunami modes that propagated north and south along the U.S. West Coast. Both observed and synthetic time series at Crescent City and North Spit are consistent with the zero-order edge wave mode solution for a semi-infinite sloping beach depth profile. Wave amplitudes at Crescent City were about twice that observed at North Spit, in spite of the fact that the source region was three times farther from Crescent City than North Spit. The largest observed amplitude was due to an edge wave which arrived almost three hours after the initial onset of the tsunami; since such waves are highly localized nearshore, this suggests that the enhanced responsiveness at Crescent City is at least partly due to local dynamic processes. Furthermore, the substantially delayed arrival of this wave, which was generated at the southern end of the Cascadia Subduction Zone, has significant implications for hazard mitigation efforts along the entire U.S. West Coast. Specifically, this study demonstrates that slow-moving but very energetic edge wave modes could be generated by future large tsunamigenic earthquakes in the CSZ, and that these might arrive unexpectedly at coastal communities several hours after the initial tsunami waves have subsided.

    Binding of Cu (II), Tb (III) and Fe (III) to chicken ovotransferrin (1990)

    Notes: Abstract The kinetics of binding of Cu (II), Tb (III) and Fe(III) to ovotransferrin have been investigated using the stopped-flow technique. Rate constants for the second-order reaction, k +, were determined by monitoring the absorbance change upon formation of the metal-transferrin complex in time range of milliseconds to seconds. The N and C sites appeared to bind a particular metal ion with the same rate; thus, average formation rate constants k + (average) were 2.4 × 104 M−1 s−1 and 8.3 × 104 M−1 S −1 for Cu (II) and Tb (III) respectively. Site preference (N site for Cu (II) and C site for Tb (III)) is then mainly due to the difference in dissociation rate constant for the metals. Fe (III) binding from Fe-nitrilotriacetate complex to apo-ovotransferrin was found to be more rapid, giving an average formation rate constant k + (average) of 5 × 105 M−1 s−1, which was followed by a slow increase in absorbance at 465 nm. This slow process has an apparent rate constant in the range 3 s−1 to 0.5 s−1, depending upon the degree of Fe (III) saturation. The variation in the rate of the second phase is thought to reflect the difference in the rate of a conformational change for monoferric and diferric ovotransferrins. Monoferric ovotransferrin changes its conformation more rapidly (3.4s−1) than diferric ovotransferrin (0.52 s−1). A further absorbance decrease was observed over a period of several minutes; this could be assigned to release of NTA from the complex, as suggested by Honda et al. (1980).

    Kinetic study on oxygenation of Lingula unguis hemerythrin using the stopped-flow 02-jump method (1990)

    Notes: Abstract O2-jump experiments with an improved stopped-flow apparatus have been used to study oxygenation and deoxygenation processes in Lingula unguis hemerythrin. With an O2 electrode set in the observation cell, O2 concentration conld be obtained directly. The reliability of this method has been compared with other conventional methods. O2-jump (up and down) experiments were carried out with L. unguis hemerythrin at pH 6.8 (non-cooperative pH) and at pH 7.6 (cooperative pH). At pH 6.8, both O2-jump (up) and O2-jump (down) experiments showed single exponential processes which were consistent with the following scheme: $${\text{Hr + O}}_{\text{2}} \mathop \rightleftharpoons \limits_{{\text{k}}_{{\text{off}}} }^{{\text{k}}_{{\text{on}}} } {\text{HrO}}_{\text{2}} $$ . The value of k on was estimated to be (4.4 ± 0.5) × 105 M−1 s −1, and k off was (15 ± 5) s−1. These values are consistent with those obtained by the temperature-jump method (Zimmer et al. 1986). At pH 7.6, O2-jump (up) experiments showed two relaxation processes, whereas O2-jump (down) experiments showed a single exponential process. The faster process in the O2-jump (up) experiments could be attributed to the same process as that seen in the temperature-jump experiments (Zimmer et al. 1986). The slower process in the O2-jump (up) experiments corresponds to the process obtained in the O2-jump (down) experiments. The results are discussed in terms of a state with intermediate affinity in O2-binding and with the possible existence of a slow step in O2-binding.

    Notes: Particle formation processes in silane plasma have been studied by means of ab initio molecular orbital method and the Derjaguin–Landau–Verway–Overbeek (DLVO) theory. The results from a quantitative comparison between the Si–H bonding energy of negative species and that of neutral ones suggested the presence of the polymerization pathways via negative species. The DLVO theory has been applied to calculate the interaction potential energy between the charged particles. It was found that the heterogeneous aggregation accelerates the particle growth. © 1998 American Institute of Physics.

    Notes: Immunohistochemical detection of 8-hydroxydeoxyguanosine, a marker of oxidative DNA damage, in human chronic cholecystitis Aims: Recent studies suggest that oxidative DNA damage induced during chronic inflammation may play a role in carcinogenesis in some organs. Although gallbladder carcinomas are frequently observed with a background of chronic cholecystitis, little is known about oxidative DNA damage in chronic cholecystitis. The aims of this study were to investigate the expression of 8-hydroxydeoxyguanosine (8-OHdG), a biomarker of oxidative DNA damage, in normal and chronically inflamed human gallbladder mucosa and compare its expression with clinicopathological findings. Methods and results: 8-OHdG expression was immunohistochemically examined using a monoclonal antibody against 8-OHdG in human gallbladder specimens. In normal gallbladder (n=5), no 8-OHdG expression was observed. In contrast, nuclear expression of 8-OHdG was detected in 28 of 31cases (90.3%) in gallbladder epithelial cells with chronic cholecystitis. The positive cells were predominantly observed in the areas of active inflammation with prominent cell infiltration. Quantitative analysis revealed that the number of 8-OHdG+ cells (labelling index) significantly (rs=0.671, P 〈 0.05) correlated with the degree of the activity of mucosal inflammation, while gender, age, and the presence of gallstones did not influence the index. Conclusions: Oxidative DNA damage is common in chronic cholecystitis, suggesting a possible link between chronic inflammation and gallbladder carcinogenesis.
