Opis:
Water stress and provenance could affect the secondary metabolites synthesis and accumulation in herbs. Thus, this study explored the effect of soil water moisture and provenance on the growth of Paris polyphylla Smith var. yunnanensis (PPY). Three provenances (Jinping, Luquan and Weixi in Yunnan, China) of PPY samples were grown in different soil water moisture conditions [0.80, 0.70 and 0.50 field capacity (FC)] during Dec. 2015 to Sep. 2017. Results showed that the highest biomass weight was presented in 0.70 FC for Luquan and Weixi samples. Biomass weight for Jinping provenance presented a decreasing tendency with the decreased soil water moisture and the highest biomass were shown in 0.80 FC. However, quantitative analysis revealed that the total content of polyphyllin increased with decreasing the soil water moisture for Jinping and Weixi samples. The highest total content of polyphyllin in rhizome was inclined to show in Jinping samples, while the stem and leaf tissues were shown in Weixi samples. Additionally, results of ANOVA combined with PCA indicated that the difference among these three provenances were significant. Correlation analysis results revealed that 0.50 FC induced the competitive relationship occurrence for polyphyllin distribution. Thus, 0.70 FC was the most suitable soil-water condition for PPY growth. Besides, provenance collected from Jinping could consider as a good quality germplasm. Consequently, this study might provide a preliminary foundation for irrigation project formulated and provenance screened for PPY cultivation.

Opis:
With the rapid development of shipbuilding industry exhaust world is also very harmful one kind of environmental issues, and the ship marine diesel engine exhaust gas is mainly produced, so in recent years it has developed a diesel engine SCR system. SCR system can control emissions of nitrogen oxides in the exhaust of vessel, furthermore air pollution can be reduced. The main goal of article was using fluent software to correct SCR system selection and flue gas flow under different size best deflector arrangement is simulated. Next goal is further optimize the structure of the SCR system.

Opis:
African swine fever is an acute, febrile and highly virulent porcine disease causing serious economic losses worldwide. The pK205R protein of the African swine fever virus (ASFV) is largely expressed in the early stages of infection, which has given the K205R gene extensive attention. In this study, the ASFV K205R was cloned and expressed in Escherichia coli BL21 (DE3). Expression of histidine-tagged pK205R with a molecular mass of 44 kDa was determined by 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot analysis. Optimisation of culture conditions allowed induction of the recombinant protein with 0.4 mM Isopropyl β-D-thiogalactoside (IPTG) at 37oC for 2 h. The protein existed in cellular supernatant and was purified using a Ni-NTA resin column. The purified protein was used to immunize rabbits four times to enable the production of polyclonal antibodies, and the antiserum titre was detected by ELISA. The results showed that the purified pK205R can react with ASFV positive serum specifically by Western blotting. The pK205R had high antigenicity, which indicated that pK205R could be used as an antigen for detection of ASFV-specific antibodies in ELISA testing, and the recombinant protein could contribute to further research of the action and structure of pK205R.
