A Long Observation of NGC 5548 by BeppoSAX: the High Energy Cut-off, Intrinsic Spectral Variability and a Truly Warm Absorber [PDF]
, 2000 NGC 5548 was observed by BeppoSAX in a single long (8 day) observation from 0.2 to 200 keV. We find (1) the spectral variation of the source is produced by a change of the intrinsic power law slope; (2) a high energy cut-off at $E_c= 115^{+39}_{-27}$ keV

The Nascent Red Sequence at z~2 [PDF]
, 2008 We present new constraints on the evolution of the early-type galaxy color-magnitude relation (CMR) based on deep near-infrared imaging of a galaxy protocluster at z=2.16 obtained using NICMOS on-board the Hubble Space Telescope.

Depressed clad hollow optical fiber with fundamental LP01 mode cut-off
, 2006 We propose a depressed clad hollow optical fiber with fundamental (LP01) mode cut-off suitable for high power short-wavelength, especially three-level, fiber laser operation by introducing highly wavelength dependent losses at longer wavelengths. The cut-

Modelling Dust Evolution in Galaxies with a Multiphase, Inhomogeneous ISM [PDF]
, 2016 We develop a model of dust evolution in a multiphase, inhomogeneous ISM including dust growth and destruction processes. The physical conditions for grain evolution are taken from hydrodynamical simulations of giant molecular clouds in a Milky Way-like ...

Evaluation of cut slope stability in the Lesser Himalaya of Nepal
GeologijaA spatial inventory of cut slopes in the central and western Lesser Himalaya of Nepal was prepared and characterised to evaluate their stability. The stability of these cut slopes is governed by the geotechnical properties of rock/soil together with ...

FIELD TEST OF SLOPE FAILURE DURING SLOPE CUTTING WORK
Doboku Gakkai Ronbunshuu C, 2009 道路拡張工事や急傾斜地対策工事では，重力式擁壁などの対策工を設置して最終的な安定性を向上させることが多い．しかし，これらの施工中には，法面勾配を従前よりも一時的に急勾配とする切土掘削作業や，床付けに伴う法尻部の掘削作業など，法面全体が不安定化するような作業が行われており，労働災害となる事例が多く報告されている．本報告では，高さ5m，斜面勾配45°の実物大盛土斜面にて切取り工事中の斜面崩壊を再現する実験を実施し，斜面下部の掘削切取りによる斜面崩壊メカニズムの解明，ならびに施工中の安全を担保する計測機器の最適配置位置の検討を行った．
