National prestige and economic interest : Dutch diplomacy toward Japan 1850-1863

This thesis discusses Dutch diplomacy with respect to Japan in the period 1850-1863, predominantly on the basis of Dutch primary sources that were not widely known or not published until present. The political and economical importance of the Netherlands East Indies made Asian Affairs always essential for the Netherlands. Moreover only the Netherlands as Western power maintained a centuries long relationship with Japan. How special this relationship was showed particularly when Japan was in the process of being opened up in the middle of the nineteenth century. Dutch diplomacy at this crucial moment in time has been portrayed as rather passive and neutral. This study, however, examines The Hague’s diplomatic initiatives from the theory of Dutch imperialism, and reaches the opposite conclusion. The Netherlands engaged in an autonomous and positive diplomacy toward Japan in order to promote its prestige and profit, and in doing so it played an important role among the larger Western powers. Although The Netherlands judged by its size has often been ranked among the small countries of Europe, this thesis evaluates it as a middle-sized power on account of its political and economic interests as a prominent colonial power in Asia.LEI Universiteit LeidenIsaac Alfred Ailion Foundation, the Canon Foundation, Japan Society for the Promotion of ScienceColonial and Global Histor

Survey observations of emission-line stars in the Orion region

Survey observations were conducted for H alpha-emission stars in the Orion region using the Kiso Schmidt telescope and partly the CTIO Curtis Schmidt telescope. In the area of about 25 square degrees, a total of 236 H alpha-emission objects, mostly supposed to be T Tau type stars, have been detected among which 155 are new ones including 6 non-stellar objects. Celestial coordinates and V-magnitude are measured for the detected objects. Eye estimation of the H alpha-emission intensity is also made at three epochs in a time span of about two years, where notable variation of H alpha intensity was found in 68 out of 236 objects. Besides a remarkable concentration along the northern dark cloud complex, a loose concentration is noticed near the Orion Belt region, fairly well coinciding with the distribution of the Orion OBIb association members. A comparison with the Av-map is also made to see the relationship between the distribution of emission-line objects and that of interstellar dust

Out-of-plane dielectric constant and insulator-superconductor transition in Bi_2Sr_2Dy_{1-x}Er_xCu_2O_8 single crystals

The out-of-plane dielectric constant of the parent insulator of the high-temperature superconductor Bi_2Sr_2(Dy,Er)Cu_2O_8 was measured and analysed from 80 to 300 K in the frequency range of 10^6-10^9 Hz. All the samples were found to show a fairly large value of 10-60, implying some kind of charge inhomogeneity in the CuO_2 plane. Considering that the superconducting sample Bi_2Sr_2(Ca,Pr)Cu_2O_8 also shows a similar dielectric constant, the charge inhomogeneity plays an important role in the insulator-superconductor transition.Comment: RevTex4 format, 5 pages, 3 figures, submitted to J.

Inhibitory effect of ferulic acid and isoferulic acid on the production of macrophage inflammatory protein-2 in response to respiratory syncytial virus infection in RAW264.7 cells.

We investigated the effect of ferulic acid (FA) and isoferulic acid (IFA), which are the main active components of the rhizoma of Cimicifuga heracleifolia (CH), an anti-inflammatory drug used frequently in Japanese traditional medicine, on the production of macrophage inflammatory protein-2 (MIR-2) in a murine macrophage cell line, RAW264.7, in response to respiratory syncytial virus (RSV) infection. Following the exposure of cells to RSV for 20h, the MIP-2 level in condition medium was increased to about 20 ng/ml, although this level in mock-infected cells was negligible. In the presence of either FA or IFA, RSV-infected cells reduced MIP-2 production in a dose-dependent manner. These data suggest that FA and IFA might be responsible, at least in part, for the anti-inflammatory drug effect of CH extract through the inhibition of MIP-2 production

One-sided jet at milliarcsecond scales in LSI+61303

We present Very Long Baseline Interferometry (VLBI) observations of the high mass X-ray binary LSI+61303, carried out with the European VLBI Network (EVN). Over the 11 hour observing run, performed 10 days after a radio outburst, the radio source showed a constant flux density, which allowed sensitive imaging of the emission distribution. The structure in the map shows a clear extension to the southeast. Comparing our data with previous VLBI observations we interpret the extension as a collimated radio jet as found in several other X-ray binaries. Assuming that the structure is the result of an expansion that started at the onset of the outburst, we derive an apparent expansion velocity of 0.003 c, which, in the context of Doppler boosting, corresponds to an intrinsic velocity of at least 0.4 c for an ejection close to the line of sight. From the apparent velocity in all available epochs we are able to establish variations in the ejection angle which imply a precessing accretion disk. Finally we point out that LSI+61303, like SS433 and Cygnus X-1, shows evidence for an emission region almost orthogonal to the relativistic jet.Comment: 7 pages, 4 figures, LaTeX, uses aa.cls.
