To evaluate terahertz time-domain spectroscopy (THz-TDS) as a promising tool for discriminating pharmaceutical tablets, THz-TDS has been applied for discrimination between pharmaceutical tablets with sound-alike names. Two sets of medicine tablets with sound-alike names, that is, Amaryl and Almarl, Zyloric and Zantac, are examined in this study. Based on the difference in THz absorption spectra, we have succeeded in distinguishing between sound-alike medicine tablets clearly for each set. The results in this study suggest that THz-TDS is a useful tool that is indispensable for medical security maintenance, such as a non-destructive way to prevent mix-up of medicine. © 2013 Springer Science+Business Media New York.

Ordinary Kriging, OK, and Regression Kriging, RK, are the spatial statistical methods that are possible toestimate a horizontal distribution in a study area from discrete data. OK is the method which takes account ofonly spatial auto-correlation structure of the data, while RK is the method which takes account of an interrelationshipbetween spatial auto-correlation structure and some auxiliary variables to minimize the estimation error.Analytical processing for OK and RK methods was performed by the R-Language (R Core Team, 2012)and its some additional libraries. The auxiliary variables required to perform RK method were prepared by aGIS application, Quantum GIS (Quantum GIS Development Team, 2012). The 3-dimensional geographic representationof the estimation maps was performed by the Google Earth (Google, 2012).In this report, OK and RK methods were applied to one of the Earth scientific information, SPM (SupendedParticulate Matter). Then, these methods were considered by comparing two estimation maps, and finallyconsidered qualitatively by displaying these maps in the Google Earth.

The absorption spectra of three kinds of medicines both before and after the expiration date: Amlodin OD (R) (5 mg), Basen OD (R) (0.2 mg) and Gaster D (R) (10 mg) have been measured by terahertz time domain spectroscopy (THz-TDS). All the medicines show some differences in the THz absorption spectra between medicines before and after the expiration dates. X-Ray powder diffraction (XRD) studies of all medicines suggest that the polymorph of the main effective compound is not changed before and after the expiration date. Therefore, the differences in the THz spectra between medicines before and after the expiration dates arise from aging variation of diluting agents and/or from modifications of intermolecular interaction between the effective compounds and diluting agents.

Inyoite was found as fissure fillings in calcium borate minerals, which occur as an irregularly shaped body in the crystalline limestone near the gehlenite-spurrite skarns at the Fuka mine, Okayama Prefecture, Japan. Inyoite occurs as aggregates of tabular crystals up to 1 mm wide, and rarely as euhedral crystals up to 0.5 mm wide in fissures of calcium borate minerals such as nifontovite, pentahydroborite, sibirskite and parasibirskite. The fissure fillings are composed only of inyoite. This is the first finding of inyoite in Japan. The type of occurrence is also different from those in many other localities in the world. Electron microprobe and CHNS / O analyses gave the empirical formula Ca1.99B5.96O5.92(OH)(10).8.08H(2)O on the basis of O = 24. The unit cell parameters are a = 10.616(2), b = 12.068(1), c = 8.404(1) angstrom and beta = 114.01(1)degrees. The mineral is optically biaxial negative with refractive indices alpha = 1.492, beta = 1.506 and gamma = 1.517, giving a calculated 2V = 82 degrees. The Vickers microhardness is 91 kg mm(-2) (10 g load) and the Mohs hardness number is 2.5. The measured density is 1.875 g cm(-3). It is likely that the inyoite at the Fuka mine was formed by a reaction of ground water with calcium borate minerals at a temperature of around 20 degrees C.

Ramsbeckite was found as a vein forming mineral in altered shale at the Hirao mine, Minoo, Osaka, Japan. It occurred as aggregates of euhedral granular crystals up to 0.5 mm across, in association with sphalerite, chalcopyrite, smithsonite, aurichalcite, amorphous manganese dioxide, schulenbergite, brochantite, serpierite, limonite and an unidentified mineral. It was emerald green to blue-green in color with a vitreous luster in hand specimen. An EPMA and CHNS/O analyzer gave the empirical formula (Cu(9.380)Zn(5.54)2Ni(0.034)Co(0.027)Fe(0.020) Mn-0.013)(Sigma 15.016)[(SO4)(3.871)(CO3)(0.166)](Sigma 4.037)(OH)(21.958)center dot 6.06H(2)O on the basis of O = 44. The unit cell parameters were a = 16.106 (3), b = 15.568 (2), c = 7.109 (1), angstrom, beta = 90.23 (1)degrees, and Z = 2. The mineral was optically biaxial negative with refractive indices alpha = 1.676, beta = 1.704 and gamma = 1.707, and 2V(X)(calc) = 37.8 degrees. The Vickers micro-hardness was 162 (144-182) kg/mm(2) ( 10 g load), and the Mohs hardness was 3.5. The measured density was 3.36 g/cm(3). It is likely that ramsbeckite at the Hirao mine crystallized from Cu and Zn-bearing fluids.

Dielectric measurements were carried out on suspensions of montmorillonite clay exchanged with three different counterions: sodium, ammonium, and tetramethylammonium (TMA). Only two dielectric absorption peaks could be identified for the clay sample with the TMA counterion, whereas three peaks were found for the two inorganic counterions. The dielectric process observed at around 10 GHz is due to the orientation of bulk water molecules, judging from the relaxation time and relaxation strength. The relaxation strength of the process occurring at around 10 MHz was compared with the coefficient of adiabatic compressibility obtained from ultrasound velocity measurements. The increase in the relaxation strength with decreasing compressibility indicates that the process at around 10 MHz is caused by the orientation of bound water molecules on the clay samples. The relaxation strength of the process occurring at around 10 MHz for the TMA sample was remarkably small. Furthermore, the network structure of the bound water molecules can be characterized by a property peculiar to the TMA sample, taking into account the value of its Cole-Cole parameter. Results for the relaxation strength of the process occurring at around 100 kHz were compared with those for electrophoretic mobility. This comparison revealed that discrimination between bound ions and ions in the diffuse double layer is important, and both the relaxation and electrophoretic results could be satisfactorily explained by surface polarization of the clay.

Phase relationships for FeS polymorph have been studied at the pressure of 16-20 GPa and temperature of 300-1350 K by in situ X-ray observation using a large volume high-pressure apparatus and a synchrotron radiation. Contrary to Fei's prediction [1], we found the stability field of NiAs-type phase of FeS extending at least to 18 GPa. Results of in situ X-ray observation correspond with the NiAs-hexagonal phase boundary determined by Kusaba et al. [2,3], Assuming the straight NiAs-hexagonal phase boundary, we estimate that the NiAs-hexagonal-liquid triple junction is located at 39.5 GPa and 2300 K.

The syntheses of zinc hydroxyl monophosphate Zn₂(OH)PO₄ were carried out under hydrothermal conditions of 573 K and 200 kg/cm². The crystal data are: orthorhombic, P2₁2₁2, a=8.099(1), =8.325(1) and c=5.966(1) Å. The structure was solved by three dimensional Patterson syntheses and refined by least squares methods to give a final residual index of R=0.042. There are four units of Zn₂(OH)PO₄ in a unit cell and three kinds of zinc atoms with different coordinations, where the first zinc atom is six-coordinated by four oxygen atoms and two hydroxyl groups, the second one is octahedrally coordinated by six oxygen atoms and the third one is five-coordinated by four oxygen atoms and one hydroxyl group forming distorted pyramids. The framework consists of infinite straight chains of Zn–O octahedra along c-axis, connected together by isolated PO₄ tetrahedra and distorted Zn–O pyramids. This compound is a polymorph of tarbuttite.
