A porous cellulose tape impregnated with a processing solution that includes sodium nitroprusside dihydrate, zinc formate, glycerin and methanol is a highly sensitive means of detecting sulfur ...dioxide in air. When the sample including sulfur dioxide was passed through the tape, sulfur dioxide was absorbed on the surface of the tape, and reacted with zinc nitroprusside to form a stain. The intensity of the stain was proportional to the concentration of sulfur dioxide at a constant sampling time and flow rate, and it could be recorded by measuring the intensity of reflecting light (555 nm). The detection limit was 0.03 ppm for sulfur dioxide with a sampling time of 20 s and a flow rate of 400 ml/min. Reproducibility tests showed that the relative standard deviation of response (n = 8) was 0.97% for 2 ppm sulfur dioxide (TLV-TWA for sulfur dioxide is 2 ppm). No interference was observed from acetylene (0.5%), ethanol (1 vol.%), acetone (1 vol.%), trichloroethylene (1 vol.%), carbon dioxide (99.9 vol.%), carbon monoxide (103 ppm), hydrogen chloride gas (5 ppm), ammonia (40 ppm), nitrogen dioxide (50 ppm), hydrogen sulfide (20 ppm).
The aim of this paper is to clarify characteristics of contemporary Japanese urban exterior space in terms of their spatial composition with surrounding environments. Initially the spaces enclosed by ...building volumes are extracted as 'vacant lands' in the center district of Tokyo, and their spatial articulation are analyzed as 'closure pattern'. Secondly their accesses from streets are analyzed as 'street pattern', and thirdly their functional characteristics are analyzed. Finally 13 spatial types are clarified through the above-mentioned patterns and characteristics. By comparing those types, they are structured in relationship with 5 fundamental models which represent urban agglomeration of the contemporary Japanese city.

(PIN) single crystals (S = 0.2) were investigated over the temperature range from −243°C to 300°C by means of X-ray diffraction. The diffuse scattering associated ...with atomic fluctuation was observed around the (3 0 0), (3 2 0), (3 3 0) and (3 3 3) reflection. The directions of the diffuse scattering were parallel to the 1 1 0 and 1

0. The temperature dependence of the integrated intensity of the diffuse scattering around the (3 2 0) and (3 3 3) was measured. With decreasing temperature, the integrated intensity of the diffuse scattering gradually increased. The temperature dependence of the diffuse scattering intensity in PIN was similar to that in PMN.
The aim of this study is to clarify the sectional composition of Japanese contemporary houses located on the inclined ground in terms of relations between external and internal composition. External ...composition is formed by the direction of the approach in contrast to the slope and the ground connection of the building volume. Internal composition is formed by the sectional arrangement of rooms. Then 4 types and 8 patterns of composition are found. Comparing the types and patterns, almost 3 characters are found, those are emphasis of direction of the slope, contrast between the building and the slope, and abstraction of the special quality of the slope.
To clarify the physiological roles of insulin receptor substrate-1 (IRS-1) in vivo, we made mice with a targeted disruption of the IRS-1 gene locus. Mice homozygous for targeted disruption of the ...IRS-1 gene were born alive but were retarded in embryonal and postnatal growth. They also had resistance to the glucose-lowering effects of insulin, insulin-like growth factor-1 (IGF-1) and factor-2 (IGF-2). These data suggest the existence of both IRS-1-dependent and IRS-1-independent pathways for signal transduction of insulin and IGFs. Moreover, we identified tyrosine phosphorylation of a 190-kDa protein (pp 190) as a novel substrate (IRS-2) for insulin receptor kinase in livers of IRS-1 deficient mice which can bind both P13-kinase and Ash/Grb2.
