    Notes: Abstract Coda wave quality factor (Q c ) was investigated by using digital data (100 sample sec−1) recorded by a vertical component short-period station installed for this study. The station was located in the greater Fairbanks area in central Alaska. From several hundred earthquakes recorded by this station in about a year, 27 earthquakes were selected for the above study; 7 of these selected earthquakes were located along the Alaska Wadati-Benioff zone (Pacific plate). The other 20 earthquakes were located in the area of intraplate seismicity (North American plate). The data was filtered using 9 pass-bands with center frequency varying from 1.5 Hz to 16 Hz with octave bandwidth. The values ofQ c obtained from the coda amplitude decay rates measured on the filtered data after corrections due to the recording instrument and source-receiver separation show appreciable frequency dependence. The value ofQ c varies in the range of 253 and 1190 corresponding to the frequency interval from 1.5 Hz to 16 Hz for the study area. This variation is close to that reported by others for the Kanto region of Japan. Moreover, the characteristics ofQ c obtained in the present case seem to be independent of epicentral distance and hypocentral depth.

    Earth-flattening procedure for the propagation of Rayleigh wave (1972)
    Springer

    Notes: Summary The propagation of Rayleigh waves in the earth is investigated in the period range of about 60 to 590 seconds. It has been shown that a set of earth-flattening approximations can be used to transform the heterogeneous spherical earth into plane-layered earth on which the dispersion computations by matrix method can be applied effectively to describe the fundamental mode of spheroidal oscillations involving the crust and the mantly only.

    Notes: Abstract Fermilab experiment E735 located at the CO intersection region of the $$\sqrt s = 1.8$$ TeV $$p\bar p$$ collider analysed over 900 Φ→K + K − events. Measured were the transverse momentum spectrum, the correlation between the average transverse momentum 〈pt〉 and the charged particle multiphcityN c , as well as the probability of Φ production per charged track,N Φ /N c , versusN c . We have also made an estinate of the total inclusive cross section for Φ mesons, $$\sigma (p\bar p \to \phi X) = 7.3 \pm 2.2 mb$$ .

    Inclusive charged pion production in hadron-nucleus interactions at 100 and 320 GeV/c (1994)

    Notes: Abstract An experiment has been performed with the Fermilab 30-inch bubble chamber and Downstream Particle Identifier to study inclusive charged pion production in the high energy interactions of π±,K +,p and $$\bar p$$ with thin foils of magnesium, silver and gold. The laboratory rapidity and transverse momentum distributions are presented separately for π+ and π− production. Comparisons are made with data from hadron-proton interactions and theA dependence of the cross sections in the different kinematic regions is discussed. We investigate the dependence of the cross sections on the number of observed protons ejected from the nucleus. By using our π− A data from two different beam energies, we study the energy dependence of these spectra. Comparisons are made with the VENUS string model Monte Carlo.

    Chemiluminescenz bei der Oxydation von fluorescierenden und nicht fluorescierenden Stoffen durch Wasserstoffperoxyd und Ozon (1929)

    Notes: 1. Wenn zahlreiche fluorescierende oder nicht fluorescierende Farbstofflösungen durch Wasserstoffperoxyd in Gegenwart von Ferrosulfat oxydiert werden, tritt ein Glimmen auf, das im dunklen Raume zu erkennen ist.2. Die Wellenlangen der Glimmerscheinung bei der Oxydation einiger fluorescierender Fnrbstoffe durch ozonisierten Sauerstoff sind gemessen worden.3. Kieselsaure mit etwas adsorbiertem Neutralrot zeigt in einer Suspension in Äthylallrohol bei Behandlung mit ozonisiertem Sauerstoff eine Glimmerscheinung.4. Wenn kleine Mengen eines Farbstoffes, der gutes Glimmen zeigt , rnit einem anderen Farbstoff von schwachem Glimmvermogen gemischt werden, so liefert das Gemisch bei Behandlung mit Ozon ein starkeres Glimmen als der schwächer glimmende Farbstoff allein.5. Steigerung der Temperatur führt zur Verstarkung des Glimmens bei der Oxydation von Reduktionsmitteln durch Ozon oder Wasserstoffperoxyd.6. Zunahme der Konzentration der Reduktionsmittel verursacht eine Steigerung der Glimmintensitat bis zu einem Grenewert. Wird die Konzentration weiter gesteigert, so schwacht sich das Glimmen ab und hört schließlich auf.
