Aspects of Japans Recent Relations with Asia

(Weste paper): deals with Japan's return to trading with the countries of Southeast Asia in the early 1950s and the responses of the United States and British governments. (Hirano paper): provides an overall picture of the Japanese history textbook disputes with China and South Korea in 1982 and 1986, and the repercussions of these diplomatic rows in Asia and beyond. The paper also sheds light on the internal discussion of these topics in the Japanese Diet and in government circles. (Tozawa paper): deals with the phenomenon of religious-based parties in India and Japan joining coalition governments in the 1990s. In India, the religious-based party, Bharatiya Janata party, formed (with allies) the government in 1998. In Japan the religious-based party, Komeito, joined the coalition government led by the Liberal-Democratic party in 1999.history, international relations, export trade (Japan), Great Britain, China, South Indian National Congress, Bharatiya Janata party, Komeito, Soka Gakkai, Liberal-Democratic party, religion, Buddhism, Hinduism, religion-based party, coalition government

San Francisco: 50 Years On - Part One

Dingman argues that the San Francisco settlement signaled the emergence of a new Pacific maritime order in which the United States Navy is the dominant naval force relying on significant bases in Japan. In particular, he focuses on the Yokosuka naval base whose retention was called for by the navy and became an important element in Washington's approach to the peace negotiations. Tozawa deals with the attitudes of the Yoshida government and the opposition parties to the peace negotiations and later to the ratification of the San Francisco Peace Treaty and the United States-Japan Security Pact. The points of difference were: whether Japan should negotiate with all the victors or with individual countries; whether Japan should observe disarmed neutrality; whether amendment to the Constitution was necessary. Cortazzi presents the perspective of a junior official in the United Kingdom Liaison Mission from October 1951. He gives an account of the activities of the British delegation to the San Francisco Conference and the conversations of Herbert Morrison and Robert Scott, especially with Prime Minister Yoshida. Lowe argues that British ministers and officials looked backward, influenced by economic, strategic and public opinion factors, the last referring to prisoners-of-war who had been treated harshly in Southeast Asia. The Labour government was worried over a probable revival in Japanese economic competition, referring particularly to textiles, shipping and the potteries. The British views of the treaty were much more critical of Japan than the USA. Foreign Secretary Herbert Morrison, anxious that the British contribution to the ultimate treaty should be properly acknowledged, agreed to be in San Francisco at the last moment for the signing of the peace treaty.San Francisco Treaty, Attlee Government, Herbert Morrison, Robert Scott, John Foster Dulles, Yoshida Shigeru, USA, Japan, United Kingdom Liaison Mission (Tokyo), United States -Japan Security Pact, British delegation to the San Francisco Peace Conference, Ratification, new Pacific maritime order, United States Navy, Yokosuka naval base.

Magnetoelectric Properties of (Ca1−x_{1-x}Srx_{x})2_2CoSi2_2O7_7 Crystals

We have investigated the magnetoelectric properties of (Ca$_{1-x}$Sr$_{x}$)$_2$CoSi$_2$O$_7$ ($0\leq x\leq 1$) crystals with a quasi-two-dimensional structure. In Ca$_2$CoSi$_2$O$_7$ ($x=0$), a canted antiferromagnetic transition occurs at 5.6 K. The transition temperature $T_{\rm N}$ is increasing with increasing Sr concentration, and the rises of the magnetization and dielectric constant become larger. Since the dielectric constant shows large change at $T_{\rm N}$ and the magnetocapacitance effect is observed below $T_{\rm N}$, a coupling between the magnetism and dielectricity is strong in (Ca$_{1-x}$Sr$_{x}$)$_2$CoSi$_2$O$_7$. The positive magnetocapacitance is reduced by Sr substitution, and is not observed in $x\geq 0.5$. Namely, the compound of $x\geq 0.5$ does not show the magnetic-field-induced electric polarization. On the other hand, the negative magnetocapacitance is enhanced by Sr substitution.Comment: 4 pages, 2figures, proceeding of International Conference on Magnetism 200

Fusion of Sendai virus with the target cell membrane is required for T cell cytotoxicity

INFECTION of mice with viruses can generate cytotoxic T lymphocytes (CTL) which show restricted specificity for target cell lysis. Specific lysis requires that the virus used to prime the target cells must be of the same type as that used to sensitise the CTL, and that both target and CTL cells must express the same major histocompatability complex (MHC) gene product(s). The nature of the viral gene product(s) and their interaction with the MHC gene product(s) have been the subject of recent stud1−5. Previously we used Sendai virus to show that lysable target cells can be obtained using membrane vesicles which contain only the viral glycoproteins, indicating that these may be the specific viral gene products involved in target formation5. Sendai virus contains two glycoproteins—the haemagglutinin-neuraminidase (HANA) which promotes attachment of virus to cells and the fusion protein (F) which is involved in subsequent virus cell fusion7−9. Both activities are necessary for insertion of these viral glycoproteins into the plasma membrane of the cell10. In this letter we suggest that the insertion of the viral glycoproteins into the cell membrane is an essential step in target cell formation since we can show that virus containing an inactive fusion protein precursor (F0) cannot elicit T cell cytotoxicity unless the fusion activity is generated by proteolytic cleavage of the precursor. Sugamura et al. 6 have suggested that it is primarily the F glycoprotein of the Sendai virus envelope which is essential for the formation of the target antigen, as virus lacking the functional activities of F following trypsin digestion was inactive in priming target cells for T cell killing. However, we show that proteolytic inactivation of either of the two glycoproteins (F or HANA) of virus used to prime target cells will abolish the cytotoxic response
