The first-order transition from the monoclinic α-phase to the orthorhombic β-phase in K_2ZnBr_4 and Rb_2ZnI_4 is investigated by X-ray diffraction. The structure of β-phase is confirmed to be isostructural with disordered β-K_2SO_4. Although structures of α and β-phases are different so much with each other, the transformation proceeds without cracking or deforming the crystal.

Morale and the evolution of norms

This paper provides theoretical insights into the diversity of economic performances within organizations. Diverse morale and the evolution of norms interact in nontrivial ways. Individuals can acquire and internalize their norms through socialization. The process by which norms evolve exhibits generalized increasing returns. There are two steady states with different effort levels. If the norm, which is enforced by altruism, persists in the limit, everyone chooses the high effort level and high morale is sustainable. On the other hand, if the norm, which is enforced by envy, is persistent, everyone chooses the low effort level and the performance decays in the long run.

Culture, effort variability, and hierarchy

This article investigates how culture affects economic outcomes in a behavioral model of the firm hierarchy which consists of a principal and an agent. In a society with two cultural orientations, the agent has to adopt the principal’s culture to work. Coordination requires an additional cost if the agent has to change cultures. Effort is not subject to contract. Given effort variability, different coordination costs can generate different effort levels among firms. There are effort complementarities between the parties, which enforce a multiplicity of possible equilibrium outcomes. Even though culture may cause the inefficient outcomes, market forces cannot reduce the freedom to preserve cultural identity.

Dynamical Susceptibility of Proton in a Two-Morse Potential

Dynamical susceptibility for a proton tunneling system is investigated by using the linear response theory and the mean field approximation. The double-minimum self-potential is constructed by a two-Morse potential, whose parameters are fixed to represent O?H stretching mode. Quantum mechanical calculations give a dynamic susceptibility showing a pronounced soft mode. The phase transitions for KDP and DKDP are described qualitatively, if an effective interaction between protons and a phenomenological damping factor are introduced. The temperature dependence of the dynamical susceptibility is discussed.

Numerical study on production processes of vibrationally excited molecules in hydrogen negative ion sources

Production processes of vibrationally excited hydrogen molecules and their effects on H- production are studied theoretically by using a set of particle balance equations in a steady-state hydrogen plasma. For vibrational excitation, three processes, i.e., fast-electron collisional excitation, neutralization of moleculer ions, and atom-surface recombination, are taken into account. Enhancement of vibrational excitation including vibrational distribution and H- production is obtained as a function of three different excitation processes.

Although optimizing the magnetic filter position and the plasma grid potential is one of the most effective factors to enhance H- yield, details concerning their roles are not now clarified well. In this article, spatially resolved measurements of the electron energy distribution function, plasma fluctuations, and plasma parameters are presented. On the basis of these experimental results, we will discuss the roles of both the magnetic filter and the plasma grid biasing voltage Vb on enhancement of H- production and extraction of H- ions.

To investigate electron energy dependence of pure H- volume production, we have recently designed a double-plasma-type negative ion source. In this source, both energy and density of fast electrons are well controlled. With the use of this source, the effect of fast electrons on H- production, i.e., the so-called two-step process of H- production, is discussed.

Effects of cesium vapor injection on H- production in a tandem source are studied theoretically and parametrically as a function of different surface processes. Model calculation is done by solving a set of particle balance equations in steady-state hydrogen discharge plasmas. By including H- surface production processes caused by H atoms or positive hydrogen ions, enhancement of H- production observed experimentally is reproduced in the model.

8-[(E)-Styryl]-1-azaazulenes stereospecifically react with dimethyl acetylenedicarboxylate to form trans-7H-6a-azacyclobuta[j]cyclopent[cd]azulene (3), which undergoes thermal rearrangement into 3-[(E)-styryl]3H-2a-azacyclopent[cd]azulene and 3a,4-dihydro-3H-2a-azadicyclopent[cd, ij]azulene (7), or isomerization into 3H-2a-azacyclopenta[ef]heptalene by silica gel. Compound 7 is oxidized during the course of reaction to yield 11-oxo-2aH-7,10b-methano-2a-azacyclopenta[ab]cycloundecene, compound 3 forming 5a,6-dihydro-3H-2a-azadicyclopenta[ef, kl]heptalene upon reaction with acetylene. The formation of 3 could be accounted for in terms of a symmetry-allowed thermal [_π2_s+_π2_a+_π6_a] cycloaddition.

X-ray study of the dielectric anomaly at 161K of thiourea

The dielectric constant has a sharp peak at 161K in the ferroelectric phase and obeys a global Curie-Weiss law in a wide temperature range including the modulated phase. Excess X-ray scatterings are observed in the ferroelectric phase, which suggest that discommensurations remain as domain walls. The dielectric constant as a function of applied electric field indicates the oscillatory interaction between the discommensurations above 161K. The dielectric anomaly at 161K is attributed to a change of the interaction from oscillatory to exponential damping in the ferroelectric phase.

The mean spacing of the ferroelectric domain walls was estimated from the peak position of the X-ray diffuse scattering. The mean distance depends on the sample thickness along the ferroelectric axis. The anomalous maximum of the dielectric constant at 161K is discussed from the experimental results about the size effect and the electric field effect.

The structural transitions from the normal phase I to the incommensurate phase II, the commensurate phase III and the commensurate phase IV were reinvestigated. Sometimes additional supperlattice reflections were observed around the III-IV transition. The successive transition is explained by a phenomenological free energy. Based on the model, the condition for appearance of the intermediate phase between phases III and IV is discussed.

The effect of intrauterine transplantation (IU group) as a potential immunologically privileged site on the diabetic state of the recipient was compared with that of conventional intraperitoneal transplantation (IP group) using Fischer 344 rats. Islets were isolated from the pancreata of normal rats and transplanted into the uterus and peritoneal cavity of the isogenic rats with experimental diabetes, which were treated with estradiol benzoate and progesterone. Although all the rats in both groups became normoglycemic within 4 days after transplantation, all of those in the IU group relapsed into a diabetic state up to the 20th day after transplantation. On the other hand, 6 of 8 rats in the IP group remained normoglycemic throughout the experimental period. Weight gain and diminution of urinary glucose excretion in the IU group were significantly lower than those in the IP group (P<0.01). The glycosylated hemoglobin level in the IU group did not differ significantly from that in the IP group, but the serum level of fructosamine in the IU group was significantly higher than that in the IP group (P<0.01). These results indicate that the response to fluctuations of blood glucose of islets in the uterine cavity is less than that of islets in the peritoneal cavity. Histologically, islets were observed to be aggregated in the uterine cavity, however the number of cells decreased markedly with time. Although this study demonstrated that blood glucose was normalized by transplantation of islets into the uterine cavity of diabetic rats, long-term survival of the islets in this location was not obtained.

Time characteristics of luminescence from quantum well have been examined using time-correlated single photon counting method. The decay time of the luminescence from single quantum well is shorter than that of bulk samples. The rapid decay is considered to reflect the enhancement of recombination due to localization of carriers. The decay time of the luminescence from multi quantum well is longer than that of the single quantum well and depends on wavelength. This dependence is explained by assuming the well size fluctuation.

The decay time of luminescence from a multi-quantum well has been measured at 20K by using a CW mode-locked dye laser and a synchroscan-streak camera. The decay time is found to increase when an electric field is applied. The increase is considered to be attributable to the field-induced carrier separation. The present results are compared with those reported by other researchers.

Multilayered manganese oxide films were prepared on a platinum electrode by potentiostatic oxidation of aqueous Mn^<2+> ions in the presence of n-tetra-alkylammonium compounds. Alkylammonium cations were intercalated between manganese oxide layers to balance the negative layer charge. Effects of several preparative parameters such as the size of alkylammonium molecules, counteranions, and bath composition on the structure of products were investigated. The interlayer distance of the products increased with increasing alkyl chain length up to C4, and the change became obviously small among C4?C6 compounds. The multilayer formation was achieved only when the manganese concentration was lower than 10 mM, and the highest crystallinity was obtained from a bath composed of 2 mM manganese sulfate and 50 mM alkylammonium chloride. At low concentrations of alkylammonium (<10 mM), a product intercalated with hydrated protons was formed, in which the protons were generated by anodic oxidation of Mn<2+> with H_2O.

Theoretical phase diagrams for {N(CH_3)_4}_2CuBr_4 crystal are constructed using the phenomenological approach developed earlier for {N(CH_3)_4}_2MCl_4 family crystals. Expressions for thermodynamic potentials of the phases presented on the experimental phase diagram, and for boundaries between these phases are derived. The theoretical temperature-pressure phase diagram is plotted and is found to be in agreement with the experimental diagram. The approximations and assumptions made when constructing theoretical diagrams are discussed.

SDS-PAGE analysis of Dirofilaria immitis extracts demonstrated the complexicity of protein components of microfilariae, similar to that of adult male and female worms. Immunoblotting analysis using sera from microfilaremic and amicrofilaremic dogs with D. immitis infection suggest that antigenic components in the low molecular weight region may be related to the anti-microfilarial mechanism of the host.

Bone mineral density (BMD), distribution of its density and bone histomorphometric parameters were evaluated in lumbar vertebra of normally growing miniature pigs. The fourth lumbar vertebra (L4) of the Gottingen miniature pig were used in this cross-sectional study in vitro. The BMD of the miniature pig was similar to that of humans in tendency of gender differences and some growth patterns during puberty. In these regards this animal appears useful as a model for human bone study. However, the trabecular and cortical BMDs of lumbar spine were extremely high value (399.43 ± 26.36 mg/cm^3 in female trabeculae

A two dimensional electrostatic particle simulation was done to study the extraction of positive (negative) ions from a volume plasma source. The simulation model is a rectangular system which consists of an extraction grid (left wall), a plasma grid, and a grounded wall (right wall). Upper and lower boundaries are connected by the periodic boundary condition. Full dynamics of charged particles are followed. Positive (negative) ions are extracted from the plasma region through a slit in the plasma grid to the extraction grid. Electrons are reflected by the magnetic filter and confined in the region to the right of the magnetic filter. Simulation results are compared with the Child-Langumuir law where the extracted ion current is proportional to the three-halves power of the potential of the extraction grid. In the case of the positive ion extraction, simulation results agree quite well with the Child-Langumuir law. Whereas, in the case of the negative ion extraction, simulation results agree with the law only for the lower value of extraction grid potential.

The spatial growth of the instability and the nonlinear interaction between a small cold beam and a warm background plasma are examined by means of particle simulation. Up to the first maximum in the amplitude oscillation of the wave, quantitative measurements confirm the predictions based on the single wave model: the magnitude of the growth rate, monochromaticity of the unstable mode, the maximum wave amplitude, and the phase space orbits of the beam electrons. After the first maximum of the wave amplitude, the spatial dependence of the wave amplitude cannot be explained by the single wave model predictions and the wave power is anomalously overdamped by a factor of 0.1 smaller than the predicted value in the first minimum. The extended single wave model equations suggest that this anomalous phenomenon is caused by weak collisions of the order of ν/ωp~10-3 within the background plasma.

Energy metabolism in the Wistar rat brain was studied by means of in vivo nuclear magnetic resonance spectroscopy after heating. The 31P-spectra were recorded at 10 minutes after heating the brain to 44 or 45℃ (cortical temperature) for 30 minutes on 6 rats in each group. Thereafter, the 31P-spectra were repeatedly recorded until 1 hour after heating. The 31P-spectra showed no significant changes of pH and high-energy phosphate levels occurred for 1 hour after heating of the brain to 44℃ for 30 minutes. However, those determined 10 minutes after heating the brain to 45℃ for 30 minutes showed a statistically significant reduction of the PCr/Pi ratio without accompaning a pH shift and change in ATP concentration. No further changes occurred thereafter for 1 hour after heating of the brain. The heat-induced PCr/Pi ratio reduction observed in this study reflected mitochondrial dysfunction and not a decline in cerebral blood flow. The present study has demonstrated at least part of the heat-induced damage of the brain occurred at mitochondrial level in vivo, while cerebral enerfy metabolism was found to be preserved up to cortical brain temperature of 44℃.

四国西部、幡多半島東岸地域の後期漸新世~前期中新世の清水層・在岬層の混在相は、火山礫岩や火山性砂岩、含火山岩礫泥岩などの火砕岩を含む。火砕岩は、中期始新世の石灰岩を伴うことがある。火砕岩の多くは、土石流や乱泥流などの堆積物重力流に由来する。火砕岩中の火山岩は、アルカリ岩系の火山岩であり、アルカリ玄武岩、粗面安山岩、粗面岩およびコメンダイトからなる。アルカリ玄武岩や粗面安山岩には緑泥石や方解石で充填された発泡痕を有する。アルカリ玄武岩にはカンラン石仮像が含まれる。火山岩類はかなりの程度の変質作用を被っており、ほとんどの苦鉄質鉱物は、緑泥石などの粘土鉱物やFe-Ti酸化鉱物で置換されている。変質過程での移動が少ないと考えられる元素を使ったいくつかの判別図から、火山岩は海洋島起源のプレート内アルカリ岩と推定される。後期漸新世~前期中新世のある時期に四国西部の収束域で海山の衝突があったと考えられる。

Fluorescence spectra due to nitrogen laser excitation were measured for silk cloths colored with some red and purple natural dyes. Identification of these dyes on silk was made possible by the use of laser-induced fluorescence method, since the respective dyes are characterized by their fluorescence spectra. Moreover, it became possible to identify each dye even on faded cloths in this experiment. Results gained by reflection spectra were compared with those obtained by laser-induced fluorescence method.

Amination of 8-amino-3-phenyl-1-azaazulene gave 1,8-diamino-3-phenyl-1-azaazulenium salt (2). Reactions of the salt (2) with triethyl orthoformate and acetic anhydride gave 1-phenyl-2a,3,5-triazabenz[cd]azulene derivatives (3a and 3b). The compound (3a) was also obtained by the reaction of 2 with diethyl ethoxymethylenemalonate in the presence of potassium carbonate. The reaction of 2 with ethyl pyruvate gave 4-acetyl-1-phenyl-2a,3,5-triazabenz[cd]azulene (3c). The structure of 3c was deduced by X-Ray structure analysis. Reaction of 2 with acetylenic esters in the presence of potassium carbonate gave 2a,3-diazabenz[cd]azulene derivatives (10a, b).

Electron spin resonance (ESR) spectra have been measured in X-ray-irradiated CdS-doped glass as functions of X-ray dose and effective X-ray energy. The intensity of the ESR signal is proportional to X-ray dose up to 40 Gy. CdS-doped glass is more sensitive than a commercial alanine dosimeter. The intensity of the ESR signal decreases with decreasing effective X-ray energy for energies lower than 33 keV. Thermal stability was also studied. The ESR signal is relatively stable at room temperature.

The reaction of 1-methyl-1-azaazulen-2(1H)-one (1a) with dimethyl acetylenedicarboxylate (DMAD) or dibenzoylacetylene (DBA) in refluxing acetonitrile gave 1,2-disubstituted azulene (2), 2-methylcyclopent[de]isoquinolin-3(2H)-ones, 1-methyl-1-azacyclopent[cd]azulen-2(1H)-ones, and 3-substituted 1-methyl-1-azaazulen-2(1H)-ones, whereas in refluxing t-butylbenzene, compound 2 and 6,8-etheno-1-methylcyclohepta[b]pyrrol-2(1H)-one were obtained as major products. The reactions proceeded periselectively depending on the temperature. 2-Hydroxy-1-azaazulene behaved as 1-azaazulen-2(1H)-one and the reaction with DMAD gave similar result as for 1a. The reaction of 2-amino-1-azaazulene with DMAD gave methyl 2,4a-dihydro-2-oxo-1,4a-diazabenz[a]azulene-4-carboxylate and tetramethyl 4,5-dihydro-1H-1,11-diazacyclohept[a]azulene-2,3,4,5-tetracarboxylate. The reaction of 2-mercapto-1-azaazulene with DMAD gave tetramethyl 4,4a-dihydro-4a-azabenz[a]azulene-1,2,3,4-tetracarboxylate in moderate yield. The reaction mechanisms of these reactions are discussed.

The successive phase transitions of mixed crystal systems of LiRbSO_4-LiNH_4SO_4 were studied by X-ray diffraction, dielectric measurement, thermal analysis and SHG detection as functions of temperature and ammonium concentration x. Although the ammonium ion is almost of the same size as the rubidium ion, a small amount of ammonium reduces the transition temperatures and the incommensurate and the fivefold commensurate phases of LiRbSO_4 fade out for x>0.1. With further replacing rubidium by ammonium, the antiferroelectric phase of LiRbSO_4 does not appear and the phase sequence is similar to LiNH_4SO_4 for x>0.25. The phase diagram and the modulated structure are discussed in reference to an Ising model with long range interactions.

The evolution of laser photo-detached and background electrons in a glow discharge plasma containing negative ions was followed using a two-dimensional particle-in-cell simulation code. Emphasis was placed on the short timescale (20 ns after photo-detachment for the parameters of a typical glow discharge plasma) behaviour because this is the timescale of the recently developed laser Thomson scattering technique combined with photo-detachment. A plasma consisting of background electrons, positive argon ions (Ar^+) and negative oxygen ions (O^-) was treated. The loss of photo-detached electrons from the photo-detachment region quickly forms a potential structure in a short time of 2 ns. The potential traps the remaining photo-detached electrons. The profile of the trapped photo-detached electrons is hollow. The loss of the photo-detached electrons from the photo-detachment region is compensated by the bulk electrons coming from the ambient plasma

Isotope effect on H^-/D^- volume production is studied by measuring both VUV emission and negative ion density in the source. In a double plasma type source, under some discharge conditions, extracted D^- currents are nearly the same as H^- currents, although VUV emission intensity (corresponding to production of vibrationally excited molecules) in D_2 plasmas is slightly lower than that in H_2 plasmas. Considering the factor √<2> due to mass difference, D^- ion density in the extraction region of the source is higher than H^- ion density. In another experiment with a rectangular arc chamber, axial distributions of H^-/D^- ion densities in the source are measured directly using a laser photodetachment method. Relationship between H^-/D^- production and plasma parameter control with using a magnetic filter (MF) is discussed. Furthermore, relative intensities of extracted negative ion currents are discussed compared with the negative ion densities in the source. Production and control of D_2 plasmas are well realized with the MF including good combination between the filament position and field intensity of the MF. Extracted H^- and D^- currents depend directly on negative ion densities in the source.

Effects of cesium vapor injection on H^- production in a tandem volume source are studied numerically as a function of plasma parameters. Model calculation is performed by solving a set of particle balance equations for steady-state hydrogen discharge plasmas. Here, the results with a focus on gas pressure and electron temperature dependences of H^- volume production are presented and discussed. Considering H^- surface production caused by both H atoms and positive hydrogen ions, enhancement of H^- production and pressure dependence of H^- production observed experimentally are qualitatively well reproduced in the model. For enhancement of H^- production, however, so-called electron cooling is not very effective if plasma parameters are initially optimized with the use of a magnetic filter.

2-Chlorocyclohepta[b]pyrroles reacted with o-phenylenediamine to give 2-(2-aminoanilino)cyclohepta[b]pyrroles (2a,b) in good yields. Treatment of 2a and 2b with polyphosphoric acid afforded cyclohepta[1',2': 4,5]pyrrolo[1,2-a]benzimidazole (4a) in good yields. Treatment of 2b with acids gave 6-(ethoxycarbonyl) derivatives (4b) of 4a and 12H-5,13-dihydrocyclohepta[1',2': 4,5]pyrrolo[2,3-b][1,5]benzodiazepin-12-one (5).

The pass-wear durability and recording characteristics of Co-γFe_2O_3 perpendicular magnetic recording thin-film disks were measured by using a MIG-type ring head with a gap length of about 0.2μm in contact sliding use. Co-γFe_2O_3 perpendicular magnetic anisotropy films were pre- pared by annealing CoO/Fe_3O_4 multilayers deposited onto an NiO underlayer in air at 280-350℃ The Co-γFe_2O_3 perpendicular hard disk had no protective overcoat layers. The head wear was drastically improved by introducing a liquid lubricant. Reproduction demagnetization did not occur, and no damage or scratches were found after more than eighteen million passes. A D_<50> of 180 kFRPI and a low-density reproduced voltage of 143 nV_<p-p>/{turu-pm- (m/s)) were obtained for a Co-γFe_2O_3 disk with an optimized film thickness and perpendicular coercivity. It is con- eluded that the Co-γFe_2O_3 perpendicular disks are suitable for ultra-high density recording media used in contact re- cording without an overcoat layer.

Results which focus on comparing operation in hydrogen and deuterium are presented. Measurements of plasma parameters, including electron density, electron temperature, electron energy distribution function and extracted negative ion current, have been made in the source and extractor regions of an electron beam excited negative ion source. For the same operating conditions, negative ion current is found to be higher in deuterium than in hydrogen.

Pulse modulation of a negative ion volume source was investigated, both with and without a magnetic filter for various operating conditions. Without a magnetic filter, afterglow negative ion peak is observed, which was reported by some authors. Variation of afterglow peak was discussed as a function of gas pressure, discharge power, and extraction voltage. With a magnetic filter, on the other hand, there is no remarkable afterglow peak and the negative ion current during the discharge pulse exceeds all the afterglow currents for the present experimental conditions. Finally, comparison of afterglow negative ion peak (no magnetic filter case, i.e., temporal filter) with negative ion current during the discharge pulse (with magnetic filter case, i.e., spatial filter) was discussed.

The effect of laser irradiation on photodarkened CdS-doped glass has been investigated as a function of the wavelength of laser light, using electron spin resonance (ESR) and time-resolved luminescence. When the wavelength of laser light is tuned to 500 nm, the intensity of the ESR signal associated with photodarkening decreases, as does the decay rate of luminescence. This indicates laser-induced reversion of photodarkening.

A model for incommensurate transitions proposed by Chen and Walker [Phys. Rev. B 43 (1991) 5634] has been extended to describe a sub-lattice model which possesses supersymmetry. If a zone boundary mode freezes, a superstructure with supersymmetry can appear and may transform into a superstructure without supersymmetry at lower temperature. Although both superstructures belong to the same space group, the transition is either second or first order one with accompanying a definite anomaly in specific heat and susceptibility.

The static susceptibility of a quantum system is considered to discuss the structural phase transition. The linear response theory is applied with assuming a mean field treatment for the interaction between unit cells. The energy eigen state is solved exactly for the Schrodinger equation of a single particle within a two-Morse type self-potential. The parameter dependence of the transition temperature is discussed analytically, which will give a general insight into the structural phase transition. The pressure-temperature phase diagram for KDP-type crystal is constructed theoretically.

Thermoelectric materials (β″-alumina) for the alkali metal thermoelectric converter (AMTEC) have been synthesized with the use of a thermal plasma reactor based on the forced constricted type plasma jet generator. It is reconfirmed that the powder mixing ratio (i.e. the ratio between α-Al_2O_3, Na_2CO_3 and MgO), jet power and substrate position, strongly affect the synthesis of β″-alumina. Besides these, the synthesis of β″-alumina is also enhanced in the high-temperature region by oxygen injection. Those dependences are correlated with jet temperature and particle heating. The metal electrode of molybdenum is also prepared by spraying Mo powders. Porosity of the prepared films could be well controlled by varying the pressure.

The production of hydrogen negative ions H^- in a pure volume source has been studied. In our double plasma negative ion source, both energy and density of fast electrons are well controlled. Using this source, enhancement of H^- production has been achieved. The extracted H^- current in the double plasma operation is higher than that in the single plasma operation when observed under the same discharge power. Measurements of plasma parameters in the source and in the extractor regions have been carried out for both cases. Enhancement of H^- production is achieved by optimizing plasma parameters for a so-called two-step process of H^- volume production.

To understand H^-/D^- negative ion formation mechanism, isotope effects of plasma production and H^-/D^- production in volume negative ion sources are studied. Axial distributions of H^- and D^- densities in the source are measured directly by laser photodetachment method. In particular, experimental results concerning dependence of H^-/D^- density distributions on plasma parameters are presented and discussed. Isotope effect of plasma production in H_2 and D_2 discharge is observed. H^- and D^- densities have different spatial distributions, respectively, corresponding to those different plasma parameter conditions.
