Optimization of the Conditions for Using Sewage to Cultivate Navicula tenera

[ Objective] This study was to improve the biomass of Navicula tenera, and thus to provide reference for achieving the industrial production of Navicula tenera. [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.

Seasonal variations in the energy budget of Elliot's pheasant (Syrmaticus ellioti) in cage

This study aimed to discuss the energy budget of Elliot's pheasant Syrmaticus ellioti in different seasons, with life and health, good growth and normal digestion of Elliot's pheasant as the tested objects, The energy budget of Elliot's pheasant was measured by daily collection of the trial pheasants' excrement in the biological garden of Guangxi Normal University from March 2011 to February 2012. 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.

Construction and Implementation of Practice Teaching System of English Major in Local Normal Universities

English practice teaching has outstanding superiority over the extension and supplementation of English classroom teaching, and practice teaching is an indispensably important part of college English teaching. To students, cultivation of the ability of practice is vital, affecting students＇ employment and future. To universities, teaching quality has a direct impact on the development prospect of schools and decides the future of schools. Moreover, local normal universities also undertake a more important task to cultivate local high-quality talents teaching primary and junior high schools. These teaching talents undertake the great task of English teaching over primary and junior high school students, and thus the construction and implementation of practice teaching system of English major in normal universities are urgent.

Teachers Are Key Factors of Universities Peking Female Higher Normal College 1917-1922

The successful experiences that cause Peking Female Higher Normal College （PKFHNC） to complete a relatively large scale of talents training task and become the birthplace of modern female intellectuals in early 20th century China in spite of disorder of social circumstance outside and regular educational system inside are as follows. 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.

Study on Current Situation and Countermeasures of English Language Culture Teaching for English Majors in Local Normal Universities

At present, English language teaching for English majors in local normal universities in China has been restricted by many aspects of factors, and the current situation is not optimistic. The main reason for this situation is that the teachers and students of English majors in some local normal universities have some deviation in understanding the English language. The teachers can not have the right attitude towards English language culture teaching,and they make one-sided emphasis on the skill learning of English language majors,but ignore the normal teaching of professional English language culture. To improve this situation and improve the overall level of English majors in normal univerities, it requires us teachers and students to work together, improving the overall level of this course from the two aspects of ＂teaching＂ and ＂learning＂ , in order to help students to truly grasp the English language culture and skillfully use English in daily life and work.

Quantum Chemical Calculations of the Structure,Property and Stability of Penta-coordinated Carbonium Ions Derived from Normal Butane

The structure and energy of the carbonium ions formed upon protonation of butane were studied by the DFT methods. Four stable structures are identified for the protonated form of n-butane, the energy increases in the following order： C2HC3〈C1HC2〈C2HH〈C1HH, and the stability decreases in the following order C2HC3〉C1HC2〉C2HH〉C1HH. The stability of the penta-coordinated carbonium ions may be explained by the electron distribution in the three-center-two-electron bonds. The delocalization of the penta-coordinated carbonium ion CHC with three-center-two-electron bonds on positive charges was stronger than that of the penta-coordinated earbonium ion CHH with three-center-two-electron bonds and its stability was higher than that of the penta-coordinated carbonium ion CHH with three-center-two-electron bonds.

Thinking on Practical Curriculum in Normal Education

In the forefi＇ont of education reform issues, teacher training has got unprecedented attention. College students are the main force future teachers, especially whose professional skill level improvement is the one of the current problems to be solved. The key to solve the problems lies in the rational development of practical education courses. Practical curriculum is a theory of practice, whose law of development expressed as a paradigm of action research. Practical Curriculum development is a prospective co-development law practice combined with theory.

The Correlation Between Mathematics and Music---Practice With the Students of the Pedagogical Faculty in Sarajevo

In contemporary times, the principle of interdisciplinarity has been applied more and more, and based on that, the educational system allows a certain subject not to be confined any longer within the limits set by its name and it also allows the cross-curricular connectedness. Led by that, the authors came up with the idea to examine the possibilities of the application of this principle within the courses of mathematics and music. This paper examines the relationship of correlation-integration-co-ordination, or linking-conjoining-harmonizing. The sample consists of the students at the fourth and fifth year of the Pedagogical Faculty in Sarajevo. The research topic is the correlation between mathematics and music. The research problem is the possibility to successfully realize a class in which mathematical and musical activities correlate. The aim of the research is to come up with some guidelines that would lead to a more successful application of the aforementioned correlation in practice. The conclusion is that we should work more on the possibilities of applying various forms of intercorrelation between subjects, to make the class content even more appropriate to the natural environment in which the child learns in a relaxed manner.
