Asian Social Science , 2011, DOI: 10.5539/ass.v7n6p199
Abstract: The main purpose of this paper is to discuss some of the interpretations of the term “teacher”, as well as the implications for course content and design, and for the formal qualifications that might be thought appropriate for a “teacher”. It also discusses some problems existing in college English teachers themselves in China, and then calls for the urgent need for teacher training. The teacher plays a very important role in ELT (English Language Teaching) and ELL (English Language Learning). Therefore, if we want to apply creativity teaching in ELT, the first and most important thing to do is arouse the teachers’ creativity. The teachers themselves should try to improve their quality and use some teaching strategies to better their teaching effect and should also have creative mind to arrange active tasks and activities to arouse students’ interests and to cultivate their creativity.

环境科学学报(英文版) , 2012,
Abstract: The widespread distribution of polycyclic aromatic hydrocarbons (PAHs) in groundwater has become an important environmental issue. Knowledge of microbial community changes could aid in identification of particular microorganisms that are capable of degrading PAHs in contaminated aquifers. Therefore, 16S rRNA gene clone library analysis was used to identify the archaeal and bacterial communities in an aquifer sediment microcosm used for anaerobic anthracene degradation under methanogenic conditions. A remarkable shift of the archaeal community structure occurred after anaerobic anthracene degradation, but the types of the abundant bacterial phyla did not change. However, a decrease of both archaeal and bacterial diversity was observed. Bacterial genera Bacillus, Rhodococcus and Herbaspirillum might have links with anaerobic anthracene degradation, suggesting a role of microbial consortia. This work might add some new information for understanding the mechanism of PAH degradation under methanogenic conditions.

World Journal of Condensed Matter Physics (WJCMP) , 2015, DOI: 10.4236/wjcmp.2015.51002
Abstract: SnS/CdS heterojunction is a promising system for photovoltaic application. SnS thin films were thermally evaporated onto CdS/ITO coated glass substrates. The structure of the device was glass/ ITO/CdS/SnS/In/Ag and I-V curves of the fabricated devices were measured under dark and illuminated conditions, respectively. We discussed the relationship of the thickness and annealing temperature of CdS buffer layers with the performance of SnS/CdS heterojunctions. The optimum thickness and annealing temperature of the CdS buffer layers were 50 nm and 350°C, respectively. The best device had a conversion efficiency of 0.0025%.

Abstract: Objective: Percutaneous coronary intervention (PCI) via the radial artery access has more advantages than that of femoral artery access, while radial or (and) brachial artery have tendency to be spasmodic. We sought to investigate the effectiveness and safety of guiding catheter crossing over spasmodic radial or (and) brachial artery segments by the aid of PCI wire and balloon compared with traditional anti-spasmodic approach. Methods: The clinical data of 168 patients with coronary artery disease (CAD) (group A), whose PCI was performed via radial artery access with radial or (and) brachial artery spasm or (and) dissection and guiding catheter passing through spasmodic segments successfully by the aid of PCI guiding wire and balloon were analyzed retrospectively, simultaneously, the other 73 patients (group B) who used conventional approach to cross over the spasmodic radial or (and) brachial artery segments were treated as the control. The success rate, the time consumption and the complication were compared between the two groups. Findings: There was no significant difference in the spasmodic site between the two groups (all p value > 0.05). The success rate in group A was significantly higher than that in group B (168(100%) vs 28 (38.4%), p < 0.0001). As for those of successful crossover in the two groups, the time consumption of guiding catheter crossing over spasmodic segment in group A was shorter than that in group B (p < 0.0001). The incidence of forearm hematoma in group A was lower than that in group B (7(4.2%) vs 14 (

SpringerPlus , 2013, DOI: 10.1186/2193-1801-2-98
Abstract: The standard molar enthalpy of combustion (ΔcHom) and formation (ΔfHom) of quaternary ammonium tetrachlorozincate [n-CnH2n+1N(CH3)3]2ZnCl4 have been determined for the hydrocarbon chain length from even number 8 to 18 of carbon atoms (n) by an oxygen-bomb combustion calorimeter. The results indicated that the values of ΔcHom increased and ΔfHom decreased with increasing chain length and showed a linear dependence on the number of carbon atoms, which were caused by that the order and rigidity of the hydrocarbon chain decreased with increasing the carbon atoms. The linear regression equations are -ΔcHom =1440.50n +3730.67 and -ΔfHom = 85.32n + 1688.22.

Jie Zhang,Bo Long,Shuying Cheng,Weibo Zhang
International Journal of Photoenergy , 2013, DOI: 10.1155/2013/986076
Abstract: Copper zinc tin sulfur (CZTS) thin films have been extensively studied in recent years for their advantages of low cost, high absorption coefficient (≥104?cm?1), appropriate band gap (~1.5?eV), and nontoxicity. CZTS thin films are promising materials of solar cells like copper indium gallium selenide (CIGS). In this work, CZTS thin films were prepared on glass substrates by vacuum evaporation and sulfurization method. Sn/Cu/ZnS (CZT) precursors were deposited by thermal evaporation and then sulfurized in N2 + H2S atmosphere at temperatures of 360–560°C to produce polycrystalline CZTS thin films. It is found that there are some impurity phases in the thin films with the sulfurization temperature less than 500°C, and the crystallite size of CZTS is quite small. With the further increase of the sulfurization temperature, the obtained thin films exhibit preferred (112) orientation with larger crystallite size and higher density. When the sulfurization temperature is 500°C, the band gap energy, resistivity, carrier concentration, and mobility of the CZTS thin films are 1.49?eV, 9.37???·?cm, ?cm?3, and 3.89?cm2/(V?·?s), respectively. Therefore, the prepared CZTS thin films are suitable for absorbers of solar cells. 1. Introduction Cu2ZnSnS4 (CZTS) is one of the promising materials for absorbers in thin film solar cells because of its excellent properties for obtaining high efficiency; that is, it has a direct band gap of 1.51?eV, very close to optimum band gap of semiconductor used for photovoltaic conversion, and high absorption coefficient (≥104?cm?1) [1]. At the same time, it has versatile electrical properties which can suitably be tailored and tuned to the specific need in a given device structure [2–5]. Various methods have been reported to fabricate the CZTS thin films including thermal evaporation [6], sputtering [7], pulsed laser deposition [8], electroplating [9], and hydrazine process [10]. The best efficiencies reported for the pure CZTS solar cells so far have been 8.4% using thermal evaporation and sulfurization [11]. In the study, the CZTS thin films were deposited using a 150°C vacuum thermal evaporation process and subsequent short (5?min) high-temperature (570°C) atmospheric pressure annealing. Though the efficiency of the solar cells is high, the annealing temperature is a little high and it does not correspond to the designing rule of solar cells. Therefore, choosing a lower sulfurization temperature to produce CZTS thin films is important. In our study, we also use thermal evaporation and sulfurization method to produce CZTS thin films.

Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.47019
Abstract: Source and occurrence of Excess Coalbed Methane is a long-term concern research topic in Coal Geology and Structural Geology. Since it is essential to understand the outburst mechanism of coal gas, and to support the coalbed methane development projects as the theoretical basis. We found in the study that, huge imparity is behind the evolutionary trend on molecular structure and the mechanism of influence from different deformation. The thesis demonstrates its probable routes of gas evolution according to distinct deformation mechanisms of coal. In the role of brittle deformation mechanism, a rapidly formed advantage rupture surface along with sliding motion from which has worked on coal. As another result, mechanical energy has transformed into friction and kinetic energy during the process. Kinetic energy increases simultaneously, which brings some results, that the new generated gas molecule. While the chemical structure of coal remains in a steady-state and do not react easily an outburst with gas. Mechanical energy turns into strain energy through its ductile deformation mechanism. The dislocation or lamellar slip made disordered between the constitutional units of aromatic rings and aromatic lamellas, as soon as secondary structural defects created. On another hand, molecular motion accelerates and splits off the small molecular on the side chain, due to the dissociation of aromatic nucleus; CH4? gas molecular was generated and placed in the secondary structural defect of coal, along with a great deal of strain energy in non-steady-state. By breaking away the balance maintaining terms, huge strain energy releases suddenly, small moleculars are free from the secondary structure defect, react outburst with gas. Furthermore to extend the discussion of the conventional physical ideas on coal absorb gas, according to the phenomenon of exceeded CBM, the gas molecular has a significant chance existing in a low bond energy of chemical bonds of coal structure.

Energies , 2012, DOI: 10.3390/en5082708
Abstract: Small-scale bio-energy projects have been launched in rural areas of China and are considered as alternatives to fossil-fuel energy. However, energetic and environmental evaluation of these projects has rarely been carried out, though it is necessary for their long-term development. A village-level biomass gasification project provides an example. A hybrid life-cycle assessment (LCA) of its total nonrenewable energy (NE) cost and associated greenhouse gas (GHG) emissions is presented in this paper. The results show that the total energy cost for one joule of biomass gas output from the project is 2.93 J, of which 0.89 J is from nonrenewable energy, and the related GHG emission cost is 1.17 × 10 ?4 g CO 2-eq over its designed life cycle of 20 years. To provide equivalent effective calorific value for cooking work, the utilization of one joule of biomass gas will lead to more life cycle NE cost by 0.07 J and more GHG emissions by 8.92 × 10 ?5 g CO 2-eq compared to natural gas taking into consideration of the difference in combustion efficiency and calorific value. The small-scale bio-energy project has fallen into dilemma, i.e., struggling for survival, and for a more successful future development of village-level gasification projects, much effort is needed to tide over the plight of its development, such as high cost and low efficiency caused by decentralized construction, technical shortcomings and low utilization rate of by-products.

Abstract: Because plants are sessile organisms, the ability to adapt to a wide range of environmental conditions is critical for their survival. As a consequence, plants use hormones to regulate growth, mitigate biotic and abiotic stresses, and to communicate with other organisms. Many plant hormones function pleiotropically in vivo, and often work in tandem with other hormones that are chemically distinct. A newly-defined class of plant hormones, the strigolactones, cooperate with auxins and cytokinins to control shoot branching and the outgrowth of lateral buds. Strigolactones were originally identified as compounds that stimulated the germination of parasitic plant seeds, and were also demonstrated to induce hyphal branching in arbuscular mycorrhizal (AM) fungi. AM fungi form symbioses with higher plant roots and mainly facilitate the absorption of phosphate from the soil. Conforming to the classical definition of a plant hormone, strigolactones are produced in the roots and translocated to the shoots where they inhibit shoot outgrowth and branching. The biosynthesis of this class of compounds is regulated by soil nutrient availability, i.e. the plant will increase its production of strigolactones when the soil phosphate concentration is limited, and decrease production when phosphates are in ample supply. Strigolactones that affect plant shoot branching, AM fungal hyphal branching, and seed germination in parasitic plants facilitate chemical synthesis of similar compounds to control these and other biological processes by exogenous application.
