概要: The traditional elastoplastic constitutive equation with a single smooth yield surface is extended so as to describe the dependency of the direction of a plastic stretching on a stress rate or a stretching. Besides, the loading criterion for the extended constitutive equation is formulated. Further, it is shown that a direction of plastic stretching cannot be arbitrary but has to fulfill an inequality under the loading criterion. 続きを見る

概要: In order to determine the optimal condition for propagation of Quercus acutissima, shoot propagation, root formation and somatic embryo propagation have been tested using several elite clones. Concerning shoot propagation the concentration of BAP supplemented was effective. The kind and concentration of auxins added affect root formation. The concentration of sucrose is important for embryo propagation. However, it becomes evident that these sensitivities are dependent on individual clones. 続きを見る

概要: By some significant institutional incentives and technological improvements, agriculture in Vietnam has made a remarkable progress in its intensity and productivity for the last decade. It resulted in a significant change in agricultural production and rural economy. Nowadays, although Vietnam becomes the third largest rice exporting-country in the world, the farmer’s living standards have not much been improved due to the present unfavorable price condition of rice and relatively high price of input materials. Environmental problems also become to be a new issue particularly in the advanced areas in the Mekong delta region where a highly intensive cultivation of rice in continuous triple cropping system has been practiced. Recent researches showed that diversified farming seems to be better for smalllscale farmers, and through integrated farming systems development approaches rice-based agro-ecosystems can be turned to more profitable farming for a sustainable agriculture and rural development. Introduction of appropriate farming practices can make better uses of lands, water and other resources at lower costs and maintain the sustainability of the environment. Integration of non-rice crops, livestock, aquaculture and other activities into rice systems can become a new approach to farmers. The present paper is aimed to review the outlines of the recent activities in research, extension and training for sustainable agriculture and rural development in Vietnam. 続きを見る

概要: A 40-day experiment was conducted to determine the effects of feeding level on growth and feed conversion efficiency in silver sea bream with an average initial body weight of 86 g. The fish were fed a commercial feed at different feeding rates from 1.0 to 2.5% (with 0.5% increments) of body wet weight per day (w/day) at 23.1±1.1℃. Each feeding rate was administered to groups of 20 fish. Growth rate, as measured by the percent body weight increase, and condition factor increased with increasing ration. Feed efficiency was better at 1.5% ration. There was no difference in feed efficiency between fish fed 2.0 and 2.5% w/day, under the applied meal programme. Based on the growth and feed efficiency data, optimum feeding rate was estimated to be 1.22% w/day. 続きを見る

概要: Pot experiments were conducted in sand culture to evaluate the effect of irradiance on the utilization of nitrate by soybean (Glycine mM: (L.) Merr. cv Orihime) during the podfilling period. Different irradiant conditions were obtained by shading the plant stands with a cheesecloth. At 55%ambient light the dry matter, the seed yield, and the nitrogen utilization were reduced in a nitrate nutrition but those were only slightly affected in an ammonium nutrition. When 0 and 2 milimolar nitrate were applied, the reduction in carbon exchange rates, leaf nitrate reductase activity and leaf nitrogen concentration took place earlier in high irradiance than in low irradiance, but the irradiant conditions did not affect the final dry matter production, the seed yield and the nitrate utilization. An increase in irradiance was required for a greater dry matter and seed production and higher nitrate utilization when 10 milimolar nitrate was applied. A decrease in irradiance lowered the nitrate uptake rather than its assimilation, which ultimately led to a lower utilization of a high level of nitrate applied. 続きを見る

概要: Flounder, Paralichthys olivaceus larvae of different ages (1, 9, 18 and 27 days after hatching) were exposed for 120 h under food deprivation at various salinities (0, 4, 8, 12, 16, 20, 32, 36, 40, 44, 48 and 52). Mortalities were recordid every 24 h. Salinity levels at which 50% larvae survived over the entire test period (120 h) were 16-36 for l-day-old larvae, 16 and 20 for S-day-old, 8-32 for 18-day-old and S-20 for 27-day-old larvae. The greatest overall survival was recorded at 16 for 1 and g-day-old larvae and 12 for 18 and 27-day-old larvae. The results suggest that flounder larvae can better withstand abrupt decrease rather than increase in salinity below ambient levels, and that the salinity tolerance of the larvae varies with age and exposed time. 続きを見る

概要: We established enzyme-linked immunosorbent assay (ELISA) which can detect 0.4-4 ng/ml of IgE by an avidin-biotin method, and 2-20 ng/ml of IgG or 5-50 ng/ml of IgM by direct ELISA methods. The ELISA methods were applied to measure serum immunoglobulin titers of Brown Norway rats intraperitoneally immunized with various amounts of fl-lactoglobulin using an alum adjuvant. Induction of antigen-specific IgG was predominant at high antigen doses such as 100 and 1000 pg/rat, but markedly decreased at low antigen doses such as 1 and 10 ,ug/rat. Induction of antigen-specific IgE was not so affected by antigen dose, but was much weaker than IgG induction and was temporal. 続きを見る

概要: The gene coding for y-polyglutamate production stimulating factor (psf) from Bacillus subtilis (natto) plasmid pUH1 was cloned and sequenced in Bacillus subtilis host. The activity of y-glutamyltranspeptidase (r-GTP) in B. subtilis host, which was introduced the psf gene was relatively high level, while its activity in E. coli host could not be detected. The nucleotide sequence of psf gene was determined and an open reading frame encoding a plypeptide composed of 420 amino acid residues (Mr, 49, 356) was identified. The putative -35 and -10 sequences, TTCAAA and TATTAT, were observed as the consensus sequence for the promoter recognized by the σ^<43> RNA polymerase of B. subtilis, and the ribosome binding site, whose sequence was AACGAG, was complementary to the binding sequence of B. subtilis 16s rRNA except for one base. The amino acid sequence of psf with the segment of putative protein C403 of staphylococcal plasmid pE194 indicates homology, whereas that with E. coli and mammalian r-GTPs does not show any similarity at all. 続きを見る

概要: Leaf photosynthetic rate, leaf conductance, specific leaf area, stomata1 size and stomata1 density of triploid and diploid cultivars of Cmtomeria japonica D. Don were measured in order to clarify gas exchange characteristics of triploid C. japonica. Cultivar cv. Measa (diploid : 2x), cv. Ayasugi (2x) and cv. Hinode (triploid : 3x) were used for the measurements. The photosynthetic rate on a leaf area basis was 50% higher in the triploid than in the diploids. Photosynthetic rate on a leaf weight basis was not significantly different among the cultivars. Specific leaf area (SLA) in the diploids were 30% higher than in the triploid. Mesophyll width in the triploid was 57% higher than in the diploids. In the leaf conductance measurement, 5.2 times more conductance in the triploid than in the diploids was observed. Stomata1 density in the triploid was 27% lower than the diploid. The difference in leaf conductance between the triploid and the diploids was mainly caused by difference in stomata1 conductance. Both of the stomata1 size and mesophyll width in the triploid were 40 to 60% higher than in the diploids. The difference in the photosynthetic rate on a leaf area basis and in the leaf conductance values between the triploid and the diploids were induced by the deference in mesophyll and stomata1 cell size in proportion to the ploidy level. 続きを見る
