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

The aim of this work is to study the histology of this cladoceran by light microscopy so as to expand the knowledge of this species. The parthenogenetic females were fixed in formaldehyde 4%. Sections were cut 3 μm thick and stained with Hematoxylin and Eosin. The intestine has simple cuboidal epithelium with apical projections and the cells have 1 or 2 nucleoli in their nuclei. Two compound eyes were found and no naupliar ocelum. The ovary is saccular and it is presented in a pair at both sides of the intestine with follicles in different states of development. The striated muscle with notorious microfibrills is recognized in antennas, antennules and trunk appendices. This article may represent the first detailed description of the histology of this species.展开更多

A discrete SEIT model with age and infection age structures is formulated to investigate the dynamics of the disease spread. The basic reproduction number R0 is defined and used as the threshold parameter to character- ize the disease extinction or persistence. It is shown that the disease-free equilibrium is globally stable if R0 〈 1, and it is unstable if R0 〉 1. When R0 〉 1, there exists an endemic equilibrium, and the disease is uniformly persistent. The stability of the endemic equilibrium is investigated numerically.展开更多
