Literature and psychology has been linked together starting from Plato and Aristotle period. In the neuropsychological domain, synaesthesia allows people to combine several perceptions together; while in literature, it magically melts the “voice” of the author’s into the works. To interpret the female voice of the book, this article analyzes the voice of poverty and distress, of pursuing ethnic equality, and of pursuing female independence, on the basis of the psychological perception, synaesthesia, so as to reveal Sandra Cisneros’s feminist voice on the reflections of ethnic Mexican female values by her beautiful naive poetic language, with a pure and innocent tone.展开更多

In order to assess the antifouling efficacy of selected marine organisms, methanolic extracts of these organisms were tested against different fouling bacterial forms and II-instar stage of the barnacle, Balanus amphitrite. Antibiosis, bioactivity and followed by multivariate analyses were carried out to check the efficacy of antifouling effect of the selected marine organisms. Principal component analysis revealed the exemplary antifouling efficacy of the sponge extracts of Stylissa sp. observed followed by Hyrtios sp. against bacterial forms in the laboratory study. De-trended correspondence analysis confirmed that the contribution of antifouling efficacy of the selected sponge extracts was observed to be more towards Bacillus sp., Vibrio sp. and Alteromonas sp. Moreover, the efficacy of Hyrtios sp. extract(20.430 μg m L^(-1)) followed by Stylissa sp.(30.945 μg m L^(-1)) showed higher against barnacle instar compared with other extracts in the bioactivity assay. Bray-Curtis cluster analysis under paired linkage categorized all the sponge extracts into one major cluster with 75% similarity, and one outlier tunicate. More than 80% similarity observed between Hyrtios sp. and Stylissa sp. Fourier transform infrared spectroscopy(FTIR) showed that the contribution of major peaks found in the marine organisms were towards sulfones, sulfoxides, cyanates and ketones.展开更多

The numerical results show that the polarization and Curie temperature will both become large sensitively due to the large values of JB and the small value of ΩB of the defect layers. Meanwhile, the dependence of the crossover values of the exchange interaction JA, the transverse field ΩA of the bulk material on the exchange interaction JB and the transverse field ΩB of the defect layers are shown in 3-Dimensional （3-D） figures for the first time. Moreover, the transition features of the ferroelectric thin film with defect layers are presented.展开更多

A nonlinear time-dependent VIV model is developed in this paper based on a VIV lift force model and the Morison equation. Both the inline vibration induced by the flow due to vortex shedding and the fluid-structure interaction in the transverse direction are included in the model. One of the characteristics of the model is the response-dependent lift force with nonlinear damping, which is different from other VIV models. The calculations show that the model can well describe the VIV of deepwater risers with the results agreeing with those calculated by other models.展开更多

CCHFV is widely distributed in countries around the world.Outbreaks of CCHFV infection in humans have occurred in prior years in Xinjiang Province, China.Epidemiological surveys have detected CCHFV RNA in ticks and animals; however, few isolates were identified. In this study, we identified and isolated a new CCHFV strain from Hyalomma asiaticum asiaticum ticks collected from north of Tarim Basin in Xinjiang, China. A preliminary investigation of infection and antigens expression of CCHFV was performed in newborn mice. The target tissues for CCHFV replication in newborn mice were identified. The analysis of the phylogenetic relationships with other Chinese strains suggested that diverse genotypes of CCHFV have circulated in Xinjiang for years. These findings provide important insights into our understanding of CCHFV infection and evolution as well as disease prevention and control for local residents.展开更多
