The purpose of this study is to analyze the concept of language proficiency and notice the difficulty of defining proficiency, especially in differentiating among what is commonly thought to be ‘beginning’, ‘intermediate’, and ‘advanced’ levels. We need to recognize methodological differences among teaching classes of beginning, intermediate and advanced students and apply concepts of accuracy, fluency, comprehensibility, grammaticality, and sociolinguistic appropriateness to an...

Culture influences the teaching of English to speakers of other languages in six basic ways. Each can become a component of instruction. First, the learner has learned how to learn by means of native culture patterns, values, and behaviors. Second, the intercultural educator accommodates to students' culturally derived learning styles and strategies in order to deliver effective instruction. Third, learning a language becomes easier when the whole personality of the learner is engaged. Fourth,...

with a 0.1% Ni-Fe catalyst at 450℃. The surface area of Chestnut-like carbons were 2401 m2/g. Additional specific capacitances of Chestnut-like carbon are significantly higher than those of other activated carbons. Chestnut-like carbon electrodes show approximately 44% retention of the specific capacitance, which is higher than that of the virginity activated carbon. Thus, Chestnut-like carbon electrode can be predicted to yield better performance in the capacitive deionization (CDI) process.

is further enhanced in the case of high relative humidity (RH) and in the presence of NH3. The reaction on Al2O3 under different gas concentration ratios is compared, and it is identified that SO2 and NO2 concentrations make an effect on aerosol production. The heterogeneous reactions of SO2 and NO2 on various coal ash are different. The order of reactivity of the three coal ashes is WH>MHU>Centennial. The secondary particulate matter formed on coal ash is higher than that on single metal oxide.

coal(LRC), which can be directly applied to existing boilers. However, due to the existence of alkali and alkaline earth metals(AAEMs) in molasses, the impregnation of molasses into the coal pores possibly lead to the ash deposited on the surface of the heat exchanger, thus reducing the heat exchange efficiency. Besides, a part of fine particles will emit into the atmosphere, resulting in a series of air pollutions. Thus, the investigation of ash deposition and fine particle formation is a...

The surface discharge induced plasma chemical process(SPCP) was applied to decompose nitric oxide(NO). The operating condition was optimized in order to maximize the NO decomposition efficiency. The highest NO decomposition efficiency obtained was 94.3% at the power consumption of 19.8 W for the frequency of 10 kHz. NO decomposition efficiency increased with increasing residence time or with decreasing initial concentration of NO. As the thickness and melting point of the electrode increased,...

NF-kB inhibitor, TPCK (10 and 20 mM). The levels of MMP-8 were measured with specific immunoassay in the supernatant after 1 through 6 hours. NF-kB activity was measured using Western blotting. LPS stimulation to cord blood significantly raised the level of MMP-8 with the passage of time, while NF-kB inhibitor by TPCK restrained the MMP-8 elevation by LPS stimulation. MMP-8 production by cord blood with LPS stimulation was repressed by NF-kB inhibitor, TPCK. Our data suggests that NF-kB has a...
