    Beschreibung: On the occasion of the Great East Japan Earthquake disaster, we rapidly distributed maritime safety information for ships. Attention−seeking for drifting obstacles made up the largest number of the issued navigational warnings, and others were information on the aids to navigation, occurrence of earthquake and tsunami, nuclear accident, etc.

    Beschreibung: Muography consists in observing the differential absorption of muons - elementary particles produced through cosmic-ray interactions in the Earth atmosphere - going through the volcano and can attain a spatial resolution of tens of meters. We present here the first experiment of nuclear emulsion muography at the Stromboli volcano. Muons have been recorded during a period of five months by a detector of 0.96 m2 area. The emulsion films were prepared at the Gran Sasso underground laboratory and were analyzed at Napoli, Salerno and Tokyo scanning laboratories. Our results highlight a significant low-density zone at the summit of the volcano with density contrast of 30-40% with respect to bedrock. The structural setting of this part of the volcanic edifice controls the eruptive dynamics and the stability of the "Sciara del Fuoco" slope, which is affected by recurrent tsunamigenic landslides. Periodical imaging of the summit of the Stromboli volcano such as that provided by muography can become a useful method for studying the evolution of the internal structure of the volcanic edifice.

    Beschreibung: The muon radiography is a novel imaging technique to probe the volcanoes interior, using the capability of high energy cosmic ray muons to penetrate large thicknesses of rock. In this way it is possible to derive a 2D density map along the muon trajectory of volcanic edifices and deduce information on the variations in the rock density distribution, like those expected from dense lava conduits, or low density magma supply paths. This method is applicable also to study geological objects as glaciers, faults, oil underground reservoirs, engineering constructions, where a density contrast is present. Nuclear emulsions are well suited to be employed in this context for their excellent angular resolution; they are compact and robust detectors, able to work in harsh environments without need of power supply. On the other side, a long exposure time is required for a reasonable detector surface (~10 m2) in order to collect a sufficient statistics of muons, and a quasi-real time analysis of the emulsion data is rather difficult due to the scanning time needed by the optical microscopes. Such drawback is on the way to be overcome thanks to a recent R&D program on ultra-fast scanning systems. Muon radiography technique, even if limited to the summit part of the volcano edifice, represents an important tool of investigation, at higher spatial resolution, complementary to the conventional geophysics techniques. The first successful result in this field was obtained by a Japanese group that observed in 2007 the conduit structure of Mt. Asama. Since 2010, other interesting volcanoes have been probed with the same method: Stromboli in 2011, Mt. Teide in 2012 and La Palma in 2014. Here we discuss the muon imaging technique reporting the nuclear emulsion detector design exposed at Stromboli and results of the data analysis.

    Beschreibung: Muography uses muons naturally produced in the interactions between cosmic rays and atmosphere for imaging and characterization of density differences and time-sequential changes in solid (e.g. rocks) and liquid (e.g. melts±dissolved gases) materials in scales from tens of metres to up to a few kilometres. In addition to being useful in discovering the secrets of the pyramids, ore prospecting and surveillance of nuclear sites, muography successfully images the internal structure of volcanoes. Several field campaigns have demonstrated that muography can image density changes relating to magma ascent and descent, magma flow rate, magma degassing, the shape of the magma body, an empty conduit diameter, hydrothermal activity and major fault lines. In addition, muography is applied for longterm volcano monitoring in a few selected volcanoes around the world. We propose using muography in volcanomonitoring in conjunction with other existing techniques for predicting volcanic hazards. This approach can provide an early indication of a possible future eruption and potentially the first estimate of its scale by producing direct evidence of magma ascent through its conduit in real time. Knowing these issues as early as possible buy critically important time for those responsible for the local alarm and evacuation protocols.

    Notizen: The interfacial reactions in the Zr–Si system have been studied by in situ cross-section transmission electron microscopy (TEM) including high-resolution-mode energy-dispersive spectroscopy (EDS) and nanobeam electron diffraction (nanodiffraction). The as-deposited Zr film has a columnar structure and an amorphous interlayer is observed at the Zr/Si interface. The amorphous layer is found to grow during annealing at 400 °C. The growth of the amorphous layer consists of three stages: a rapid increase in the early stage, a gradual increase in the intermediate metastable stage, and saturation in the final stage. The kinetics at each stage are discussed with in situ TEM observation and ex situ EDS analysis. Annealing at 500 °C creates a ZrSi2 layer at the amorphous layer/Si interface. The phase and orientation relationship are determined from the nanodiffraction patterns. The ZrSi2 is found to grow layer by layer into the Si substrate via a ledge mechanism. © 1995 American Institute of Physics.

    Notizen: Recently, we have successfully fabricated large-scale deoxyribonucleic acid (DNA) networks on mica surfaces using a simple fabrication method. This report describes how we fabricated a variety of structures depending on the type of DNA, and controlled these structures using a post-treatment ethanol which we observed using atomic force microscopy. We found that the height of fiber in the DNA network depended on the type of DNA and its original length, and that the fiber height and mesh diameter could be shortened and widened, respectively, with ethanol treatment. © 2000 American Institute of Physics.
