In this model, from the wave records the average of two neighboring wave periods for the extreme crest or trough was defined as the period of the Stokes wave by the up and down zero-crossing methods. Then the input wave amplitude was deduced by substituting the wave period and extreme crest or trough into the expression for the fifth-order Stokes wave elevation. Thus the corresponding formula for the wave velocity can be used to describe kinematics beneath the extreme wave. By comparison with the published numerical models and experimental data, the proposed model is validated to be able to calculate the extreme wave velocity rather easily and accurately.展开更多

Ulysses is Joyce's optimum work, which takes 3 Dublin characters' experience in one day as the main line to show the paralysation and crisis of the whole Western society, people's emptiness on their minds, loneliness on their feelings and labefaction on their spirits, also, it showed the inextricable perplexity. To treat the theme of inextricable perplexity, this paper is trying to set about the inextricable Catholic Church and identity problems, with the ideas of Alick West-the outstanding English Marxist literary critic of the 20th century.展开更多

This paper reviews the historical context of the political events from 1933 to 1945, the circumstances for the betrayal, and arrest of the group in hiding, the saving of Anne Frank's diary and its publication after her death at the Bergen-Belsen concentration camp in March 1945. Further, the paper reconstructs the beginnings of the heritage site as a small museum at 263 Prinsengracht in 1960 as well as the management issues and capacity problems that led to a larger museum complex including an educational center in 1999. During the years of 2007-2010, when the annual visitation of the museum surpassed one million, the Anne Frank House decided to introduce a high quality 3D version of the Secret Annex on the Intemet. In the final part of the paper, trends in museum management and the more frequent uses of a digital documentation of heritages sites are reviewed.展开更多

For this purpose, groups of eight ferrets (6 to 7 months old) were injected with 0.5 mL of vaccine specimens containing 3.75, 7.5 or 15.0 μg of virus hemagglutinin. Administration was intramuscular and given either as a single dose or as two doses 14 days apart. All vaccine specimens manifested immunogenicity in ferrets for single (HI titer, from 51 ± 7 to 160 ± 23) and double (HI titer, from 697± 120 to 829 ± 117) administrations. To assess the protective effects of the vaccine, ferrets from the vaccinated and control groups were infected intranasally with pandemic virus A/California/7/09 (H1N1) pdm09 at a dose of 106 106/0.5 mL. Fourteen days post-infection, the ferrets inoculated with single or double vaccines containing 3.75, 7.5 or 15.0 ~g of hemagglutinin per dose showed no signs of influenza infection, weight loss, or body temperature rise, and no premature deaths occurred. The number of vaccinated ferrets shedding the virus via the upper airway, as well as the amount of virus shed after infection, was significantly reduced in comparison with animals from the control group. Based on our results, we suggest that a single vaccination at a dose of 3.75 or 7.5 μg hemagglutinin be used for Phase I clinical trials.展开更多

The inlet guide vanes with different outlet angle are designed, which are mounted on the casing and located at the upstream of the impeller of the prototype fan. Both steady and unsteady flow simulations arc performed. The steady flow is simulated by the calculations of Navier-Stokes equa- tions coupled with RNG k-epsilon turbulence model, while the unsteady flow is computed with large eddy simu- lation. According to the theoretical analysis, the inlet guide vanes with outlet angle of 60° are regarded as the op- timal inlet guide vanes. The static characteristic experiment is carried out in a standard test rig and the aerody- namic noise is tested in a semi-anechoic room. Then, performances of the fan with optimal inlet guide vanes are compared with those of the prototype fan. The results show that there is reasonable agreement between the simu- lation results and the experimental data. It is found that the static characteristics of small axial flow fan is im- proved obviously after installing the optimal inlet guide vanes. Meanwhile, the optimal inlet guide vanes have effect on reducing noise at the near field, but have little effect on the noise at the far field.展开更多
