[ Method ] Nosema bombycis was used to feed wild type and mutant drosophila, and the morphological observation of Nosema bombycis in drosophila body fluid was also analyzed by calcofluor white M2R fluorescent staining. [ Result] Nosema bombycis could infect drosophila, and the number of Nosema bombycis in the infected mutant drosophila was higher than that in wild type drosophila. [ Conclusion ] Nosema bombycis can infect drosophila, which provides primary reference for studies on the infectivity of Nosema bombycis to other hosts and also lays a foundation for further study on the infection mechanism of Nosema bombycis.展开更多

[Method] The feasibility of using sewage to cultivate Navicula tenera was preliminarily investigated based on the consideration of regional characteristics; and a series of culture conditions including the nutrient source of nitrogen（N）, phosphorus（P）, iron（Fe）, silicon（ Si ） and the salinity in medium for culturing Navicula tenera, were optimized by single factor test and orthogonal design.[Result] The optimized conditions for cultivating Navicula tenera using sewage are as follows： the water from Xiaoerlou Artificial Lake of Nanjing University of Technology as basic solvent; 360 mg/L urea; 150 mg/L N2HPO4 · 12H2O; 50 mg/L ferric citrate; 2 000 mg/L Na2SiO3 · 9H2O; 2.0 mol/L salinity. Navicula tenera was strongly adaptive to sewage and could well uptake the nutrient sources in the sewage. Under the optimized conditions, the culture cost decreased, and meanwhile the biomass of Navicula tenera reached 4. 766 g/L which is 3.57 multiples over original medium and 1.9 multiples over optimized medium No. 1.[ Conclusion] This study laid a foundation for the combination of culturing Navicula tenera in large scale and sewage treatment.展开更多

(Holotype HNUL 03080902, adult male, SVL: 38.2 mm), from Sangzhi County, Hunan Province, is described. Megophrystuberogranulatus is closely related to both Megophrys kuatunensis and Megophrys minor. Characters of the new species that differentiatethis species from close relatives are skin granulated with big tubercles on the dorsal sides of both thigh and tibia, thebigger inner metacarpal tubercle, upper eyelid wider than the interorbital space, hind limbs longer, overlapping of the left andright calcaneal parts.

In recent years, more and more domestic scholars begin to think about the situation of China and explore the grammar teaching method. This article will review the explicit grammar instruction and implicit grammar teaching research, collect and analyze the integration of explicit grammar instruction and implicit grammar teaching strategy and its advantages in the grammar teaching.展开更多

The results showed that the gross energy consumption, metabolic energy and excrement energy varied by season, increasing as temperature decreased. There was significant difference in gross energy consumption, metabolic energy, excrement energy between adults and nonages. There was also a trend that food digestibility of pheasants increases as temperature increases. In the same season, the food digestibility of adults was better than that of nonages. Throughout spring, summer, autumn and winter, the metabolic energy of 4-year adults were 305.77±13.40 kJ/d, 263.67±11.89 kJ/d, 357.23±25.49 kJ/d and 403.12±24.91 kJ/d, respectively, and the nonages were 284.86±17.22 kJ/d, 284. 66±15.16 kJ/d, 402. 26±31.46 kJ/d and 420. 30±31.98 kJ/d, respectively. The minimum metabolic energies were 247.65±21.81 g, 265.86±26.53 g, respectively for each group, detected between 4-year adults and 1-year nonages. Further study is needed to determine whether 29.6 C is the optimal temperature for the Elliot's pheasant.展开更多

Ten participants were interviewed. An analysis of their interview transcripts, using the constant comparative method, discloses the following reasons why they do not register as members： no added benefits to current employment, difficulty in filling in the application forms, high cost of membership and lack of ambition to become accountants. The findings of this study provide insights to the professional accounting bodies and academics on the accounting graduates＇ lack of interest to become accountants.展开更多

First, with the endeavor of Chen Zhongfan, Dean of Chinese Department, PKFHNC gathered lots of leading scholars both from old school and new school during May Fourth Movement; second, these leading scholars＇ diversified academic thoughts, political ideas, and educational experiences encouraged students to think freely and critically; finally, their deep concerns about the future of China society, academic disciplines, and women＇s liberation and education caused all superficial changes and differences of PKFHNC to form an united spiritual power, which promoted this group of female students＇ development deeply.展开更多

Some transitioned from face-to-face instruction to online instruction. The aim of this study is to investigate the perceptions of both the instructors and the students as regards second language acquisition through online education at a rural university. The study was implemented in the context of teaching and learning English as a second language in an online education environment. The course material is based on The Net Languages Learning Platform, which is available at http：//ide.yok.gov.tr/, and the course level is general English pre-elementary. Both quantitative and qualitative methods were used in this study. For quantitative data collection, a questionnaire was employed to understand the reasons for low student attendance on online courses. For qualitative research method, observation was carried out, and interviews are designed as data collection techniques. Purposive selection was used for selection of the participants. The findings revealed that online education needs to be modified. The students are eager to improve their second language competencies; however, they do not want to waste their time on an easy course level.展开更多
