With reference to the characteristics of online supply chain finance, this paper establishes a credit rating index system for the loan enterprise in the online supply chain finance that is based on the third-party B2B e-commerce platform. The system applies the multi-level gray evaluation model based on the Theil index to make a comprehensive evaluation on the credit of the loan enterprise and tests the model’s feasibility through the analyses of numerical example. The evaluation model overcomes the subjectivity of weight distribution to index and presents the degree (from excellent to poor) of indices on each hierarchy distinctly so as to enable banks to take risk control specifically in operation.

Objective: The gastrointestinal tract of sheep contain complex microbial communities that influence numerous aspects of the sheep's health and development. The objective of this study was to analyze the composition and diversity of the microbiota in the gastrointestinal tract sections (rumen, reticulum, omasum, abomasum, duodenum, jejunum, ileum, cecum, colon, and rectum) of sheep. Methods: This analysis was performed by 454 pyrosequencing using the V3-V6 region of the 16S rRNA genes. Samples were collected from five healthy, small tailed Han sheep aged 10 months, obtained at market. The bacterial composition of sheep gastrointestinal microbiota was investigated at the phylum, class, order, family, genus, and species levels. Results: The dominant bacterial phyla in the entire gastrointestinal sections were Firmicutes, Bacteroidetes, and Proteobacteria. In the stomach, the three most dominant genera in the sheep were Prevotella, unclassified Lachnospiraceae, and Butyrivibrio. In the small intestine, the three most dominant genera in the sheep were Escherichia, unclassified Lachnospiraceae, and Ruminococcus. In the large intestine, the three most dominant genera in the sheep were Ruminococcus, unclassified Ruminococcaceae, and Prevotella. R. flavefaciens, B. fibrisolvens, and S. ruminantium were three most dominant species in the sheep gastrointestinal tract. Principal Coordinates Analysis showed that the microbial communities from each gastrointestinal section could be separated into three groups according to similarity of community composition: stomach (rumen, reticulum, omasum, and abomasum), small intestine (duodenum, jejunum, and ileum), and large intestine (cecum, colon, and rectum). Conclusion: This is the first study to characterize the entire gastrointestinal microbiota in sheep by use of 16S rRNA gene amplicon pyrosequencing, expanding our knowledge of the gastrointestinal bacterial community of sheep.

Ag/AgCl/activated carbon (AC) plasmonic photocatalysts were prepared by precipitation and photoreduc-tion method. The as-prepared plasmonic photocatalysts were characterized by XRD, SEM, BET, EDS, UV–visDRS, XPS and PL. The results show the composite photocatalysts are successfully obtained and obviouslyexhibit surface plasmon resonance and effectively enhance the separation of h+/e . The photocatalyticdegradation rate of tetracycline (TC) could reach 97.3% in 60 min under visible light irradiation and cycledexperiments show stably photocatalytic activities. The active species analysis displays holes andsuperoxide radicals are the main reactive species. Photocatalytic kinetic indicates that the degradationprocesses obey pseudo first order kinetic equation.

In this work, a new binary microwave dielectric ceramic system of (1 − x)CeO2–xCaF2 (0.2 ≤ x ≤ 0.6) was fabricated at medium sintering temperatures. The compositional eff ects of on the sintering behavior, phase compositions, microstruc- tures, and microwave dielectric properties of the samples were studied. High relative density levels (> 95%) were achieved in the (1 − x)CeO2–xCaF2 samples at the sintering temperatures ranging from 1100 to 1350 °C. An increase in the content of CaF 2 resulted in a decrease in the dielectric constant, an increase in the Q × f level, and a negative shift of the τf value. The optimal microwave dielectric properties of εr = 11.3, Q × f = 53,000 GHz, and τf = − 102 ppm/°C were obtained in the sample of (1 − x)CeO2–xCaF2 with x = 0.6 when sintered at 1300 °C.
