The former is found to mark accusative, genitive and dative cases. The latter, on the other hand, renders the functions of contrastive focus marking, converb marking, declarative clause marking in the affirmative perfective, and coordination. After a thorough description of their functions, it is attempted to propose as to whether the various roles rendered by the two forms relate to distinctive homophonous morphemes or to a single morpheme. The required data for this study were collected from native speakers primarily through elicitation, and this method was supplemented by recording free narratives. 展开更多

Superoxide dismutase (SOD) activity in the leaves of transgenic tobacco plants with betaine aldehyde dehydrogenase (BADH) gene was about 36% higher than that in the control plants (parent plants), activities of per-oxidase (POD) and catalase (Cat) increased by about 62% and 88% respectively. Activities of ascorbate peroxidase (AsSPOD), dehydroascorbate redutase (DAsAR) and glu-tathione reductase (GR) in ascorbate-glutothion pathway located at chloroplasts increased by 67.7%, 47.9% and 38.8% respectively. These results indicated that the H2O2 produced by SOD catalyzing superoxide anion radicals (O2-) could be fully decomposed, and could not derive to form the strongest toxicant radicals · OH. This is the first report to elucidate quantitatively that the activities of two kinds of antioxidative enzymes decomposed radicals and active oxygen were matched. Photoinhibition tolerant capacity of the transgenic tobacco plants was 35% higher than that in the parent plants. Increment of photoinhibition tolerant 展开更多

This article first outlines the principle of a cognitive semiotics,and in this framework presents a sign classification taking into consideration the crucial importance of time.It then offers a stratified interpretation of the Lotmanian concept of semiosphere,and continues with a study of the contradiction holding between cultural and socio-functional meanings.This leads to an analysis of ethnic passions and ethnic identity,and finally to a new analysis of homo metonymicus,and the two underlying cognitive structures based on the genitive and the dative schemas,that orient the human imaginary,for better or for worse. 展开更多

The hydration of TBP has been studied by Karl-Fischer titration and IR spectroscopy. Recently, Ruddy found by tritium tracer technique that the species, such as TBP·H2O, (TBP·H2O)2, (TBP·H2O)4 and TBP·2H2O were present in the organic phase when TBP was equilibrated with water. 展开更多

Many pyrrolizidine alkaloids are known as antitumor agents, but they induce some lesions. Several crystal structures for these compounds have been reported. In order to understand the relationship between structure and pharmacologic function of these compounds, the crystal structures of several pyrrolizidine alkaloids have been determined in our laboratory. 展开更多

XPS studies on the structure of three important members of heteronitro-tricyclic compounds have been reported by the present authors before. Experimental results have confirmed the existence of N→B, N→Si and N→Ti dative bonds in these compounds respectively.
