Compared with the control (non-interplanting), the properties of soil humus in agroforestry system were ameliorated, with a higher level of humification and resynthesis of organic detritus. The soil microbial population and enzymatic activities were both higher under the influence of villous amomum. Both the nutrient supplying and nutrient conserving capacities of the soil were improved. This agroforestry system exhibited an advantage of improved soil fertility as well as an accelerated growth of Chinese fir, it was, therefore, a sustainable management system suited for Chinese fir in South China.展开更多

Data were collected by the way of a self-administered questionnaire with the study sample comprising students from bachelor degree programs. The results of the study offer an important view regarding the motivation for attending cultural tourism among Turkish students. The paper ends with both practical implications for the cultural tourism organizers and some theoretical contribution to the research of cultural tourism.展开更多

Twenty-one 5th graders participated in this study forty minutes per week, lasting for sixteen weeks. They were required to co-create English picture books of Pinghu through thematic task-based activities. Research data required for the study were collected through the pre-/post-tests of vocabulary and cultural knowledge, a participants' feedback questionnaire as well as semi-structured interviews. The results of this study showed that after experimental instruction, EFL 5th graders significantly improved their recognition of the connection between English word sounds and word meanings, word meanings and word forms, word forms and word meanings, as well as spellings. Moreover, their local cultural knowledge was improved significantly as well. Furthermore, based upon the 5th graders' responses to questionnaire and semi-structure interview, most of them developed a very positive attitude towards the activities of co-creating local picture books and their interest, self-confidence in English writing, and English learning behavior. Based on the findings, some suggestions were offered for the pedagogical applications and future studies.展开更多

A laboratory experiment was set-up, with a semi-arid control soil and the same soil but artificially contaminated with diesel oil, to follow changes in the dominant species of the microbial community in the hydrocarbon-polluted soil via proteomics. Analysis of the proteins extracted from enriched cultures growing in Luria-Bertani (LB) media showed a change in the microbial community. The majority of the proteins were related to gIycolysis pathways, structural or protein synthesis. The results showed a relative increase in the complexity of the soil microbial community with hydrocarbon contamination, especially after 15 days of incubation. Species such as Ralstonia solanacearum, Synechococcus elongatus and different Clostridium sp. were adapted to contamination, not appearing in the control soil, although Bacillus sp. dominated the growing in LB in any of the treatments. We conclude that the identification of microbial species in soil extracts by culture-dependent proteomics is able to partially explain the changes in the diversity of the soil microbial community in hydrocarbon polluted semi-arid soils, but this information is much more limited than that provided by molecular methods.展开更多
