This paper studies the influence factors and the influence mechanism which effect adoption intention of online customized marketing system, which is based on TRI model and the theory of resistance to marketing persuasion as the main framework of the research model from two aspects of technical and marketing characteristics. According to empirical study based on 303 Chinese users, we found that the user’s optimism, creativity and system inadaptability directly influence on the adoption intention in terms of technology attribution, marketing supply appeal, marketing supply fitness, perceived controlling and perceived pressure influence on the adoption intention in terms of marketing attribute, meanwhile, recommendation fitness are influenced by customized label, customized participation and explanation of recommendation. Marketing supply attractiveness is influenced by product attributes, novelty and form of customized supply. And users’ concern about security of system has no significant influence on users’ adoption of online customized marketing system. The people at different education are different significantly in their adaption attention. Finally management suggestion for operators was given.

Objective: The aim of the study was to investigate the effect of zinc-bearing palygorskite (Zn-Pal) on rumen fermentation by in vitro gas-production system. Methods: In trial, 90 incubators were evenly divided into five groups: control (0% Zn-Pal), treatment I (0.2% Zn-Pal), treatment II (0.4% Zn-Pal), treatment III (0.6% Zn-Pal), and treatment IV (0.8% Zn-Pal). The contents of zinc for treatments were 0, 49, 98, 147, 196 mg/kg, respectively. The main chemical composition and microstructure of Zn-Pal was investigated by X-ray diffraction. The physicochemical features were evaluated by Zeta potential analysis, cation-exchange capacity, ethylene blue absorption and specific surface area (the Brunauer–Emmett–Teller method). In vitro gas production (GP) was recorded at 3, 6, 9, 12, 18, 24, 36, 48, 60, and 72 h incubation. Incubation was stopped at 0, 6, 12, 24, 48, and 72 h and the inoculants were tested for pH, microbial protein yield (MCP), NH3-N, volatile fatty acids (VFAs), lipopolysaccharide (LPS). Results: The results showed that the GP in the treatment groups was not significantly different from the control groups (p>0.05). Compared to the control group, pH was higher at 24 h, 48 h (p<0.05), and 72 h (p<0.01) (range 6 to 7). The concentration of NH3-N in the three treatment groups was higher than in the control group at 24 h (p<0.01), meanwhile, it was lower at 48 h and 72 h (p<0.01), except in the treatment IV. The concentration of MCP in treatment I group was higher than in the control at 48 h (p<0.01). Compared with control, the LPS concentration in treatment III became lower at 12 h (p<0.05). Total VFAs in treatments were higher than in the control at 24 h, 48 h (p<0.05). Conclusion: These results suggest that the addition of Zn-Pal can improve the rumen fermentation, especially when adding 0.2% Zn-Pal.

Differential die-away technology applied to detect special nuclear materials

Lianjun Zhang,Mengjiao Tang,Chen Zhang,Yulai Zheng,Yong Li,Chao Liu,Qiang Wang,Guobao Wang Korean Nuclear Society 2023 Nuclear Engineering and Technology Vol.55 No.7

Differential die-away analysis (DDAA) technology is a special nuclear material (SNM) active detection analysis technology. Be a nuclear material shielded or not, the technology can reveal the existence of nuclear materials by inducing fission from an external pulsed neutron source. In this paper, a detection model based on DDAA analysis technology was established by geant4 Monte Carlo simulation software, and the optimal sensitivity of the detection system is achieved by optimizing different configurations. After the geant4 simulation and optimization, a prototype was established, and experimental research was carried out. The result shows that the prototype can detect 200 g of ²³⁵U in a steel cylinder shield that's of 1.5 cm in inner diameter, 10 cm in thickness and 280 kg in weight.

Xanthate-modified baker’s yeast (XMBY) was successfully synthesized by grafting xanthate groups onto the surface of baker’s yeast and was used for the simultaneous adsorption of cadmium (Cd2+) and methylene blue (MB) from aqueous solution. Scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and Fourier transform infrared spectroscopy (FTIR) were used to characterize the synthesized adsorbent. The results indicated that the sulfur groups were successfully introduced onto the surface of the baker’s yeast and participated in the adsorption processes. The kinetic and isotherm data showed good correlations with the pseudo-second-order model and the Langmuir model, respectively. The equilibrium time and the maximum values obtained from the two models were 40 min, 239.8mg/g for Cd2+ and 300 min, 64.45mg/g for MB, respectively. The thermodynamic analysis (G<0, H>0, S>0) demonstrated that the adsorption processes of Cd2+ and MB onto the XMBY were endothermic and spontaneous. In the binary-component solution (Cd2+ and MB), the adsorption capacity for MB was almost unaffected by the presence of Cd2+ and interestingly, the adsorption capacity for Cd2+ increased in the presence of MB. Overall, these results indicated that XMBY could be a promising adsorbent for the treatment of wastewater containing both Cd2+ and MB.

Continuous Passaging of a Recombinant C-Strain Virus in PK-15 Cells Selects Culture-Adapted Variants that Showed Enhanced Replication but Failed to Induce Fever in Rabbits

Classical swine fever virus (CSFV) is the etiologic agent of classical swine fever, a highly contagious disease that causes significant economic losses to the swine industry. The lapinized C-strain, a widely used vaccine strain against CSFV, has low growth efficiency in cell culture, which limits the productivity in the vaccine industry. In this study, a recombinant virus derived from C-strain was constructed and subjected to continuous passaging in PK-15 cells with the goal of acquiring a high progeny virus yield. A cell-adapted virus variant, RecCpp80, had nearly 1,000-fold higher titer than its parent C-strain but lost the ability to induce fever in rabbits. Sequence analysis of cell-adapted RecC variants indicated that at least six nucleotide changes were fixed in RecCpp80. Further adaption of RecCpp80 variant in swine testicle cells led to a higher virus yield without additional mutations. Introduction of each of these residues into the wild-type RecC backbone showed that one mutation, M979R (T3310G), located in the C-terminal region of E2 might be closely related to the cell-adapted phenotype. Rabbit inoculation revealed that RecCpp80+10 failed to induce fever in rabbits, whereas RecCpp40₊₁₀ caused a fever response similar to the commercial C-strain vaccine. In conclusion, the C-strain can be adapted to cell culture by introducing specific mutations in its E2 protein. The mutations in RecCpp80 that led to the loss of fever response in rabbits require further investigation. Continuous passaging of the C-strain-based recombinant viruses in PK-15 cells could enhance its in vitro adaption. The non-synonymous mutations at 3310 and 3531 might play major roles in the enhanced capacity of general virus reproduction. Such findings may help design a modified C-strain for improved productivity of commercial vaccines at reduced production cost.
