Nature of the Karakawa moor, Iwami-cho, Tottori Prefecture : topography, geology and vegetation

The Karakawa moor situated in the mountainous area of eastern part of Tottori Prefecture west Japan was investigated geologically and vegetationaty as the basic study for conservation of natural environments. The 26 hand orger drillings revealed the buried topography under the moor. There are small ridge and two shallow valleys under the moor. The formation of moor was promoted by deposition of dam upped sediments at the junction of these two valleys, The sediments are composed of gravel, silt and clay, volcanic ash and black organic soil (peat) in ascending order. The volcanic ash is considered as secondary deposits and identified as mixture of Aira Tn ash (ca.25ka) and Daisen Uh ash (ca.20 ± α ka) by means of thermomagnetic and also EDX analyses. From the results of fossil pollen analysis, the black organic soil is divided into three pollen zones in ascending order as follows; A zone (145-130 cm depth: Castanea & Castanopsis, Taxodiaceae &Cupressaceae, Betula, Cryptomeria), B zone (130-90 cm depth: Castanea & Castanopsis, Taxodiaceae & Cupressaceae, Cyclobalanopsis, Aesculus), C zone (90-35 cm depth: Taxodiaceae & Cupressaceae, Castanea & Castanopsis, Aesculus, Tsuga). the vegetation of the moor was inbestigated phytosociologically in 1980-1981 and 1988-1989. As the result of the studies, 5 communities were recognized. The following 3 communities with 2 sub-communities as a typical moor vegetation among them were discussed with the comparison of a secular change. 1) Eriocaulon miquelianum - Rhyncospora fauriei community 2) Hosta montana - Arundinella hirta community 　(2-1) Rhynchospora fauriei - A.hirta sub-community 　(2-2) Carex dispalata - A.hirta sub-community 3) Lythrum anceps - C.dispalata community (1) is an oligotrophic community favored by pudding water flowing from percolating underground water. (3) is an eutrophic community confined to the area near the stream.departmental bulletin pape

Competitive Reconfiguration of Adsorbed Species on Heterogeneous Solid Surfaces*

application/pdfThe competitive reconfiguration behavior of adsorbed species has been studied on the heterogeneous solid surfaces of Cr_2O_3, Ag and MgO by using the transient response method, and the characteristic anomalous transient behavior has been observed depending on the catalysts. 0n Cr_2O_3, in the temperature range 131〜163℃, the reduction of surface removing surface oxygen works to increase the degree of coordinated unsaturation of the surface sites, and the adsorption of oxygen on the reduced surface decreases the degree of it inducing the rapid desorption of CO_2 and CO_2 preadsorbed. 0n Ag, in the temperature range 80〜120℃, the desorption of CO_2 adsorbed on the oxidized surface is accelerated when H_2 is adsorbed on the surface. 0n MgO, the single gas adsorption of CO or CO_2 obeys a Langmuir isotherm on the same active sites such as coordinatively unsaturated surface O^2 ions or paired surface ions Mg^O^, in the temperature range 290-320℃. The desorption response of CO is extremely affected by the second component CO_2 mixed in the gas phase, while the desorption of CO_2 is not influenced by the ambient gas. The adsorbed CO is retained on the surface by the attraction force of adsorbed CO_2, and its amount decreases with increasing concentration of coexisting CO_2. The temperature programmed desorption spectra of the CO retained on the surface give a single peak and satisfy the first order desorption kinetics.departmental bulletin pape

Binary Neutron Star Mergers: Mass Ejection, Electromagnetic Counterparts, and Nucleosynthesis

We release dynamical ejecta data from binary neutron star merger simulations.  The outflows are extracted at a fixed coordinate sphere with radius 300 G/c^2 Msun (= 443 km). Only material unbound according to the geodesic criterion is considered to be part of the dynamical ejecta. See [1] for more details. Included data: `Table2.txt`: Table 2 of the paper in machine readable format `tabulated_nucsyn.h5`: nucleosynthesis yields from pre-computed parametrized trajectories. The first three indices of each dataset are Ye, entropy, and expansion timescale tau. For example `Y_final[iYe, ientr, itau, iiso]` gives the final abundance of isotope `iiso` with `A[iiso]` and `Z[iiso]` for a trajectory with initial Ye = `Ye[iYe]`, initial entropy `s[ientr]`, and expansion timescale `tau[itau]`. `[model].tar`: ejecta data for individual simulations. The naming convention is the same as in the paper. For each model we provide: `outflow.txt`: angle integrated outflow rate and cumulated ejecta mass. Data are given in units with Msun = G = c = 1 (eg, the conversion factor for time to seconds is 4.9258e-6). `hist_entropy.dat`: histogram of the ejecta as a function of the entropy (in kb) `hist_vinf.dat`: histogram of the ejecta as a function of the asymptotic velocity (in units of c) `hist_ye.dat`: histogram of the ejecta as a function of the electron fraction Ye. `profile.txt`: time integrated ejecta profiles as a function of the polar angle. `hist_vinf_theta.h5`: histograms of the ejecta as a function of the asymptotic velocity and the polar angle. `hist_ye_theta.h5`: histograms of the ejecta as a function of the asymptotic velocity and the polar angle. `hist_ye_entropy_tau.h5`: histograms of the ejecta as a function of Ye, entropy, and expansion timescale tau. Additionally we distribute: Initial data generated with LORENE and associated EOS tables. EOS tables used for the evolution Parameter file used for each simulation For the multidimensional histograms the indices are ordered as specified in the file name, ie the file `hist_ye_theta.h5` tabulates the ejecta mass as a function of Ye (first index) and polar angle theta (second index).
