Author | Yoshimura, Hiroshi| |
Abstract | The first aim of this paper is to express quantitatively the global standards pattern of change in industrial structure, thereby to show Revised Petty−Clark’s law that includes the back ward bending tendency of the second industry, which means that the composition ratio of the second industry changes to decrease from increase at the ratio of about 40%.And the second is to show implications and examples of application of the standards pattern. Then we will be able to attain successfully the first aim and to show the following implications and examples of application. They are ①the standards stages of economic development based on the standards pattern, ②the difference ratio of industrial structure, which means the degree of gap of the pattern of a nation from the standards pattern, and ③the converging tendency of industrial structure. |
Keywords | industrial structure global standards pattern Petty−Clark’s law standards stages of economic development difference ratio of industrial structure converging tendency back ward bending tendency |

Author | Akatsuka, Kazuya| |
Abstract | 生物学的あるいは生化学的な緩衝液を使用して作製された電子顕微鏡試料と従来の電子顕微鏡用として使用されている緩衝液で作成した試料とで電子顕微鏡像から比較検討した。HEPES緩衝液で作製した試料の電子顕微鏡像は、従来の電子顕微鏡に用いられている緩衝液で作製した試料から得られた電子顕微鏡像と非常によく似た像を示し、このHEPES緩衝液は電子顕微鏡の固定用緩衝液として使用できることが認められたが、その他(PIPES、MOPS緩衝液)の緩衝液ではあまりにも細胞内の可溶性物質が溶出しすぎて使用に耐えなかった。電子顕微鏡学研究において使用されうる固定用緩衝液は細胞内のオルガネラの保持が余りにも良い場合には、その微細構造の解析が困難になり、程々に細胞内の可溶性物質が溶出した方が解析がし易くなると思われ、この様な観点から、今回使用したHEPES緩衝液は生物学的あるいは生化学的な研究から引き続き電子顕微鏡用の試料を作製する際、同じ緩衝液が使用できることが認められた。 |

Title Alternative | 種々の長さのスペーサーをもつハプテン化ボスファチジルエタノールアミンの新しい合成法 |
FullText URL | 062_032_037.pdf |
Author | Ishimori, Yoshio| Yasuda, Tatuji| |
Abstract | The antigenicity of liposomes sensitized with haptenated phosphatidylethanolamine (PE) and the reactivity of the liposomes with complement depended on the length of the spacer between hapten and PE. To establish the optimal conditions for the assay, haptenated PE's with various length of spacers are required. In the previous method, hapten-spacer molecule was first synthesized to which PE was conjugated. Therefore, even different hapten molecules and different length of spacer molecules were used, every combination of hapten and spacer has to be synthesized. A new procedure for preparing hapten-spacer-PE was described here. We first prepared conjugates between PE and various length of spacer molecule, the terminal of which is an amino residue. These molecules react well with activated hapten molecules, giving a good yield of hapten-spacer-PE. |

Abstract | Encapsulation of thiophen and bithiophen in two kinds of hexagonal faujasites (Na-EMT and H-EMT) with various concentration of Cu(2+) ions have been investigated and characterized by means of themoanalytic and spectroscopic methods. From the results, it was found that the progress of polymerization of thiophen and bithiophen in the lattice space depended on Cu(2+) contents, and the encapsulation of thiophen in Na-EMT and H-EMT with Cu(2+) ions yielded polythiophen clusters with electron states of bipolaron. On the other hand, polythiophen clusters synthesized by the encapsulation of bithiophen in H-EMT were found to be mostly polaron states. |

Abstract | Monodispersed porous polymer microspheres having diameter of ca. 50 μm were successfully prepared by suspension polymerization of styrene, polyoxyethylene methacrylate and ethylenegycol dimethacrylate. Monodispersed O/W emulsion was firstly made by SPG membrane emulsification technique, following droplets-swelling method of monodispersed seed emulsion by the addition of secondary emulsion. The effect of solvent used in suspension polymerization on porous structure of prepared polymer microspheres was investigated in this paper by identification with scanning electron microscopy, porosimeter and the performance in gel permeation chromatography. It was found that benzene, 1-butanol and butyl acetate worked as poor solvent for polymer prepared in this study and that polymer microspheres prepared with these solvents had larger pores. Gel permeation chromatography measurements indicates that polystyrene having molecular weight smaller than 50,000-100,000 can be clearly separated by using gel columns packed with polymer microspheres prepared with poor solvents. |

Title Alternative | Consideration for the correlation between basicity of oxide glasses and chemical shift of O1s binding energy in XPS |
FullText URL | 003_145_156.pdf |
Author | Nanba, Tokuro| Miura, Yoshinari| |
Abstract | Binding energy of O1s core electron measured in XPS is a candidate to determine new scale of Lewis basicity of oxide ion in glass. Some mathematical expressions for the basicity or XPS chemical shift, such as charge parameter and optical basicity, are compared with experimental O1s binding energy in binary alkali oxide glasses. The expressions so far in use need some modification in parameters. A new empirical expression introduced in this paper gives new concept and universal scale of basicity. |

Abstract | Many fertilizers are soluble in water, therefore their effect does not last for long time after fertilizing in soils. The nitrogenous fertilizers such as urea transported to groundwater cause serious agricultural contamination and health problems. To solve these problems, sustained release of fertilizer has attracted much attention. In this study, we attempted to prepare polylactide microcapsules with fertilizer by phase separation technique, which was a method of microencapsulation. Polylactide (PLA) was used as a biodegradable polymer bacause the biodegradable polymer has no influence on the soil and the ecosystem. The effect of preparation conditions such as stirring time and fertilizer concentration on morphology of microcapsule and on cumulative percentage released of enclosed urea was also investigated. |

Abstract | Recently, many antitumor agents developed. Irinotecan hycrochloride (CPT) has a great side effect even though it is well effective against the cancer. Drug delivery system (DDS) medicine indicates that the release rate of medicine is constant for a long time. Therefore, in order to materialize the general idea of DDS, we applied microencapsulation technique to prepare biodegradable polymer microspheres (MS) enclosing antitumor drug having no side effect. Polylactide microparticles enclosing antitumor agent were prepared by solvent evaporation method under various operation conditions. The effects of operation parameter on release rate of drug and morphology of microparticles were studied. |

Title Alternative | Chemical Changes of Dredged Soil in Kojima Lake from the Viewpoint of Soil Reaction |
FullText URL | 009_137_140.pdf |
Author | Takemura, Koichiro| Adachi, Tadashi| |
Abstract | While dredged soil is increasing, the processing problem isn't solved. So it is expected to use effectively as the soil material. Although, to use dredged soil, the chemical characteristic must be grasped. It is because acidification cause material (pyrite) can be contained in dredged soil. It causes sulfulic ions when it touches air and has the possibility to become acidification. In this experiment, dredged soil in Kojima Lake was made clear that it contained in pyrite and acidified under the oxidation condition. Accordingly, when using dredged soil as ground resources, it is necessary to use as the soil material such as filling-up reclamation under the deoxidization condition. |

Abstract | Two molecular forms of α-glucosidase were isolated from spinach seeds after storage at 4℃ by CM-cellulose column chromatography and gel filtration. The molecular masses of α-glucosidase A and B were 78 kDa and 82 kDa by SDS-PAGE, and 62 kDa and 70 kDa by gel filtration, respectively. α-Glucosidase A had high activity not only toward maltooligosaccharides but also toward α-glucans. The optimum pH was 4.5-5.5 and about 50% of the activity remained after incubation at 65℃ for 20 min. On the other hand, α-glucosidase B had high activity toward maltooligosaccharides but faint activity toward α-glucans. The optimum pH was 5.0 and no activity was found after incubation at 65℃ for 20 min. The enzymatic and immunological properties of α-glucosidase A and B were similar to those of α-glucosidase. Ⅰor Ⅱ, and α-glucosidase Ⅲ or Ⅳ, isolated from spinach seeds without 4℃ storage, respectively. These findings suggest that the α-glucosidase in spinach seeds is modified to be two molecular forms. |

Abstract | Air pollution caused by suspended particulate matter (SPM) has increased remarkedly in industrial areas, and this has become an emergency issue in the global environment. Atomospheric SPM influences the local ecosystem including various plants and animals. It is necessary to examine the distribution characteristics of such trace metals in fine particulates (especially those with a diameter (φ) of less than 2.1μm). The Environment Agency of the Japanese goverment will complete analysis of the a concentration of suspended particulate matter less than 2.4μm by the end of 1999, and will be examining the relationship between the concentration of suspended particulate matter (0.1-9.0μm) with consideration given to the particle size throughout two years. It became clear that the metals of artificial origin such as Pb, V, Cd, Ni, Cr, existed in fine particulates (0.1 or more 2.0μm). By contrast, the metals of natural origin, such as Ti, Mn, Mg, Sr, mainly existed in coarse Area in Japan. |

Abstract | Pectic polysacchasides from the starch-free cell wall preparation of rice (Oryza sativa) shoots have been extracted in sequence with cyclohexane-trans-1,2-diaminetetra-acetate(CDTA)and Na2CO3. The total amount of polysaccharides extracted with the agents was estimated as approximately 1% of the cell walls. The extracted polysaccharides were fractionated by DEAE-Trisacryl M ion-exchange chromatography yielding five fractions, and the monosaccharide composition and molecular mass were constructed from homogalacturonan and rhamnogalacturoanan containing the "hairy" region with galactosyl and arabinosyl side-chains. The solubilized pectic polysaccharides after treatment with two pectolytic enzymes accounted for 0.4~0.6% of the starch-free cell walls. |

Abstract | A virus causing necrotic spots and necrotic flecks on the leaves of Vanda orchids in Japan was identified as cymbidium mosaic virus(Cymv) on the basis of host range,stabilly in crude sap, particle morphology, serological test and physico-chemical properties. The virus was transmitted by sap inoculation to 12 of 57 species in 6 of 12 families tested, but not by aphid Mizus persicae or through seeds. Systemic infection occurred in all Orchidaceae plants tested and only one in non-orchidaceae (Sesamum indicum). In Tetragonia expansa sap, the infective at a dilution of 10-5 but not at 10-6, after heating at 65℃ for 10 min, and was still active after 1 month aging in vitro. Flexuous rod particles, c. 475×13nm, were observed.In ultrahtin sections of leaf tissues from diseased plants, virus particles were found to aggregate in the cytoplasm. The molecular weight of the protein submit and RNA determined by gel electrophoresis, was 27.8×103 and 2.2×106, respectively. Double-stranded RNAs with estimated molecular weight of 5.4×106, 4.0×106, 3.6×106 and 3.0×106 were isolated from infected plants. |
