Science. 1977 Jun 03;196(4294):1104-6. doi: 10.1126/science.196.4294.1104.

Attenuation of seismic waves indicates that the earth is not perfectly elastic. Dispersion accompanying absorption gives frequency-dependent "elastic" moduli, a fact that must be taken into account when inverting seismic data. Normal mode data are reinverted after correcting for...

The two largest earthquakes of the past 40 years ruptured a 1600-kilometer-long portion of the fault boundary between the Indo-Australian and southeastern Eurasian plates on 26 December 2004 [seismic moment magnitude (Mw) = 9.1 to 9.3] and 28 March...

Line profiles of rovibrational transitions of CO embedded in p-H(2) crystals were studied by high resolution midinfrared diode laser spectroscopy. The line profile analysis for the R(0)(parallel), R(0)(perpendicular), P(1)(parallel), and P(1)(perpendicular) transitions shows that spectral line shapes are well...

A transition from hierarchical pore structures (macro- and meso-pores) to uniform mesopores in monolithic polymethylsilsesquioxane (PMSQ, CH(3)SiO(1.5)) gels has been investigated using a sol-gel system containing surfactant Pluronic F127. The precursor methyltrimethoxysilane (MTMS) undergoes an acid/base two-step reaction, in...

Numerical study on spectral properties of tungsten one-dimensional surface-relief gratings for spectrally selective devices.

J Opt Soc Am A Opt Image Sci Vis. 2005 Sep;22(9):1805-13. doi: 10.1364/josaa.22.001805.

Spectral properties of one-dimensional tungsten gratings with various depths and widths of grooves were investigated by means of finite-difference time-domain simulation with a multi-Lorentz model. Shallow gratings showed a strong absorption peak due to surface plasmon polaritons when the...

The profiling of impurities in methamphetamine (MA) using headspace solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) is described. The extraction of the impurities with an SPME fiber was examined under varying conditions. Optimal chromatograms were obtained when...

Degradation of N-hydroxy-3,4-methylenedioxymethamphetamine in aqueous solution and its prevention.

N-Hydroxy-3,4-methylenedioxymethamphetamine (N-OH-MDMA) is a lesser known psychedelic drug that has recently circulated in the Japanese illicit drug market. From the instability of the similarly structured N-hydroxy-3,4-methylenedioxyamphetamine (N-OH-MDA) in neutral-to-basic aqueous solution, it was presumed that N-OH-MDMA would also degrade...
