Previous experiments have mainly focused on the substrate choices of Aurelia spp. planulae. However, substrate preferences for the proliferation and immigration of polyps have not been reported. We monitored the propagation and immigration of Aurelia aurita(s. l.) polyps on two natural and nine artificial substrates at constant temperature(20±0.5°C) and salinity(30±0.5) in beakers and a glass aquarium in the laboratory, respectively. The results showed that, among artificial substrates, the highest number for polyp proliferation and immigration was found on nets, rigid polyvinyl chloride plates(RPVC), and wood. The lowest density of polyps was present on iron plates. Among natural substrates, the asexual reproduction rate of polyps on Patinopecten yessoensis(Jay, 1857) shells was significantly higher than Azumapecten farreri(Jones & Preston, 1904). On the account of the distinction in the roughness, chemical properties and biofilms of these material surfaces, bare artificial or natural substrates discriminatively affect the proliferation and the immigration of Aurelia spp. polyps at laboratory. These observations suggest that, even in the natural environment, different materials and texture may influence the composition and the abundance of the fouling communities and the assemblages of polyps and, indirectly, have effects on the amounts of released medusae.展开更多

Furthermore, the re- gional characters of Nanzheng County were investigated to analyze the feasibility and necessity of relocation with lots of data and evaluation was made on relocation of Nanzheng County. In addition, the existing problems of relocation were concluded and the prospect of the county was discussed, which is of significance for relocation in Nanzheng County and even southern Shaanxi Province.展开更多

Increasingly, however, immigrants and their descendants adjust and soon participate in and with the new culture（s）. At the same time, those who encounter ＂The Other＂ through the contact with immigrants, have also to adapt, to learn, and to realize considerable changes in themselves in that process. Recently, a new German novelist, Renate Ahrens, has created several major works in which she reflects on this intricate phenomenon typical of our times. The present study might well be the first critical analysis of her last two novels, Zeit der Wahrheit （Time of Truth, 2005） and Fremde Schwestern （Alienated Sisters, 2011）, which prove to be outstanding and first-rate literary treatments of the theme of＂The Other＂ in an intercultural context. As Ahrens illustrates in both novels, each individual carries a heavy baggage imposed on them by the own family history, and so in both cases the confrontation with ＂The Other＂ serves exceedingly well to break open the shell of self-isolation and self-alienation. Love finally overcomes ancient conflicts and paves the way for new integrative forces supporting the formation of the ＂global village＂ we all are really living in.展开更多

It discusses the origin of the short story in general and preconditions for the popularity of the new genre the Iranian literature of the 20th century, and also about the first successful collection of short stories that introduced it to the public. Also the development process of the short story and principle factors in every stage of its emergence as an independent genre of prose, as well as the thematic range are the main aspects among others to be analyzed in the article. It is historically documented that the Islamic state was established in 1979 after the fall of the Shah. And the very event had big impact not only on the social and political life of the country, but also on the cultural and literary life of the Iranians of the time. The significance of the revolution was such that it divided the literature to be known as the ＂pre-revolution＂ and ＂post-revolution＂ periods. Therefore this article is aimed to observe how this historic event had influenced the short story in particular and the distinct features of the works created during the two periods. The next period which stands out in the development of the short story is during the late 90s and the beginning of the 2000, where the genre experienced aesthetic innovations and experiments with new forms and styles. The distinct feature of the period is mainly in its topics it deals, among other the effects of the globalization and popular culture brought forth, isolated individual, urbanization, climate change and its destructive outcome and the social conflicts resulting from them. Such global issues caused the established writers to look out of their borders and open up to the concerns of the planet, and by doing so establishing new schools of thought and style among the writers of short story in modem Iranian literature. Finally the article will overview the role of the Iranian contemporary female short story writers, children＇s literature and the works of the immigrant Iranian authors that continue the traditions of the Persian literature outside Irma.展开更多
