Elementy japońskich wierzeń i obrzędów w mandze Mieruko-chan. Dziewczyna, która widzi więcej Tomoki Izumiego
No full textThe aim of the article is to reflect on religious themes in contemporary Japanese comics. The manga Mieruko-chan by Tomoki Izumi is analyzed. The themes include the Japanese tradition of horror, derived from folk beliefs, as well as Shintō and Buddhist rituals. The author draws attention to religion as an important element of creating cultural reality and its function that makes it more attractive.The aim of the article is to reflect on religious themes in contemporary Japanese comics.

Two-Step Transformation of Aliphatic Polyketones into pi-Conjugated Polyimines
No full textThe chemo- and stereo-selective two-step transformation of aliphatic polyketones composed of 3,3-dimethylpentane-2,4-dione units was achieved to generate pi-conjugated polyimines. Upon treatment with hydrazine, discrete oligoketones with 4-8 carbonyl groups afforded ethylene-bridged oligoisopyrazoles in 80-89% yields. These oligoisopyrazoles underwent stereoselective oxidation at the ethylene bridge to give fully pi-conjugated oligo(isopyrazole-3,5-diyl-trans-vinylene)s in 73-87% yields. Oxidation of the oligoimines drastically changed their absorption and metal-coordination behaviors. Finally, this two-step transformation was applied to polydisperse polymers. Imine formation proceeded almost quantitatively, even for longer polyketones, including docosamer. Subsequent oxidation of the polyimines furnished a virtually insoluble material that showed broad and red-shifted solid-state absorption over the whole visible region resulting from extended pi-conjugation
Supramolecular Conformational Control of Aliphatic Oligoketones by Rotaxane Formation
No full textConformational control of aliphatic oligoketones bearing two 1,3-diketone subunits is achieved by molecular recognition with pillar[5]arene. Pillar[S]arene binds to aliphatic ketones, with association constants K of similar to 10 M-1, to form pseudorotaxanes. The pseudorotaxanes are locked by BF, complexation at the 1,3-diketone sites through quasi-solid-state reactions. X-ray crystallography reveals linear conformations for the axis molecules. The effect of supramolecular conformational restriction is evaluated using an alkyl-linked dyad chromophore system that shows solvatochromism upon intramolecular aggregation

This article appeared in Tokiyoshi Umeda, Yuuki Hashimoto, Hiroyoshi Mizukami, Tomoki Shirakawa, Akihiko Fujii, and Katsumi Yoshino, Appl. Phys. Lett. 85, 3139 (2004) and may be found at https://doi.org/10.1063/1.1804234.Photovoltaic properties of heterostructure devices of titanium oxide (TiO2) and conducting polymer thin films have been studied. Normal photovoltaic properties were stably observed upon the visible light irradiation of the wavelength range corresponding to the absorption of a conducting polymer, and unique photovoltaic properties were also observed upon the ultraviolet (UV) light irradiation of the wavelength range corresponding to the absorption of TiO2. UV light irradiation caused marked increases in the short-circuit current at the visible-wavelength range and in the open-circuit voltage. These properties have been discussed by considering the enhancement of the built-in field which originates from the hole accumulation caused by the trap levels in the TiO2 layer or TiO2 ∕ conducting polymer interface.

<Review Articles>R.D .Hill. Rice in Malaya : A Study in Historical Geography. Oxford University Press. 1975

Rice in the prehistoric and early historic cultures of Southeast Asia is described in the first two chapters, which cite archaeological and historical evidence for the age and area of origination of rice cultivation and its spread to the Malay Peninsula. Rice cultivation had become widespread throughout the peninsula by the beginning of the nineteenth century, and chapter 3 illustrates the cycle of operations involved in shifting, semipermanent and permanent cultivation at that time. It also describes land tenure and the gradual changes in the concept of land as real property in Malayan society. As a means to understand the diversity of development of rice cultivation, the author proposes that four major regions of rice cultivation emerged between the nineteenth and the early twentieth century. The first is the northern region centered upon Kedah, the colonized lands of Penang and Province Wellesley, and Kelantan, Trengganu. Perak, apart from the tin-mining areas in the south, is also included and offers a fine example of development under British rule. Second, the southern region includes the plain of Malacca, which is largely non-Minangkabau in its techniques, tradition and law, together with the contrasting Minangkabau lands of Negri Sembilan. The third region, which includes southern Perak, the whole of Selangor and Pahang, comprised the 'marches' areas, where rice-growing was of little importance. The fourth region, that of the hill peoples, was only partly known during the nineteenth century. The remaining chapters focus mainly on the northern and southern centers of rice cultivation, dealing with the traditional or common cultivation methods and their distribution; acreages of paddy fields, with many statistical data on land-ownership and the races engaged in rice-growing; the socioeconomic background; and schemes for expansion of rice cultivation, the motives behind them and the fates they met. The discussion on the expansion of cultivated area in relation to the regional pattern of economic development in a colonized area indicates that large-scale development succeeded more often under Malay initiative than British. Finally, the author proposes a typological scheme which comprehends all the spatial patterns of rice-growing in the Malay Peninsula. The scheme could be used to classify the ecotypically varied pattern of rice-growing, but difficulty remains in its application to evolutional development, because multi-ancestral and different types of rice-growing were introduced into the peninsula in different ages and in different areas. On the origin and dispersion of cultivated rice in the Malay Peninsula and adjacent areas, a more detailed and precise theory should be provided by recent studies in this field. Throughout this volume, the author has successfully combined geographical and historical approaches in depicting rice in Malaya
