In recent years, a reconstruction project for sewer pipelines has been progressing in Japan with the aim of renewing old sewer culverts. However, it is difficult to secure a sufficient base area for shafts in an urban area because many streets are narrow with a complex layout. As a result, construction in such urban areas is generally very demanding. In urban areas, there is a strong requiremen...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

Feeding of fluorinated benzoic acids to fermentations of a Phoma sp. resulted in the biosynthesis of a series of novel fluorinated squalestatins. The feeding studies, isolation, structural elucidation and biological activities of these compounds are reported.

Following the oral feeding of a polyphenolic fraction isolated from green tea (GTP) in drinking water, an increase in the activities of antioxidant and phase II enzymes in skin, small bowel, liver, and lung of female SKH-1 hairless mice was observed. GTP feeding (0.2%, w/v) to mice for 30 days significantly increased the activities of glutathione peroxidase, catalase, and quinone reductase in s...

Intrigued by similar specificities of the hydra feeding receptor and y-glutamyl transferase activity toward GSH, we examined the possibility that these two GSH-bihding activities might reside in the same protein. We find that the two activities differ in specificity toward the y-glutamyl moiety of GSH. The hydra transferase recognizes L-azaserine, L-Glu, D-Glu and L-Gln. The feeding receptor re...

The binding of 4-dimethylaminoazobenzene to proteins and the enzymatic activities of some purine-catabolyzing enzymes during feeding of the carcinogen have been in vestigated by analysis of two liver fractions differing in their cytological composition. At an early stage of feeding dye binding occurred at a faster rate in nonparenchymal cells than in parenchymal cells. Binding in nonparenchymal...
