大学生社会主义核心价值观宣传教育探讨——以接受视阈为研究视角

接受视域下探讨社会会主义核心价值观宣传教育,有其充分的理论依据,是有效应对"西化"分化"的需要,有助于正确处理社会主义核心价值观与各种非核心价值观的关系,是应对网络不良信息影响的需要.宣传教育要有实际效果,必须了解宣传的对象,找准切入点和着力点;因势而谋,及时回应、回答和解决理论到实践提出的问题;应势而动,采取贴近学生喜闻乐见的宣传方式.     

产教融合视角下高职院校“双师型”教师团队建设的创新机制

"双师型"教师是高职院校教师队伍专业化的必然选择,包括"双师型"的专业教师与"双师型"的教师团队,前者是"双师型"教师队伍的个体特征而后者是队伍的团体特征。随着我国职业教育产教融合的不断深入,高职院校师资队伍的专业化水准显著提升,专业化团队的重要性和必然性凸显。因为只有高水平、专业化的"双师型"团队才能承担科技创新、人才培育和服务社会的整体功能。实现这一目标,必须深化高职院校管理体制和机制的改革,构建知识共享的产教融合平台,建立多元化教师引进和专业发展机制,构建分层分类的教师评价体系。

Application of the ISCST3 model for predicting PCDD/F concentrations in agricultural soil in the vicinity of a MSWI plant in China

Based on the Industrial Source Complex Short-Term Version 3 （ISCST3） model, a simplified modeling approach was developed to predict concentrations of congeners of polychlorinated-p-dioxins and dibenzofurans （PCDD/Fs） of agricultural soil, within a radius of 3 kin from a municipal solid waste incinerator （MSWI） plant after its 4-year operation in Hangzhou, China. Comparisons were made between the measured and estimated congener-specific concentrations and the international-toxic equivalent （I-TEQ） values of soil samples with respect to distance from the stack. The results indicate that the predictions of soil PCDD/F concentrations and K-TEQ values were generally lower than their observations, and that the higher the degree of underestimation seems, the greater the further downwind one gets. Nevertheless, most of the predictions were in good agreement with the trend of measured ones and were within a factor of ten for samples located within 1 kin of the plant. Besides, analysis of contributions of various deposition pathways confirms that in addition to wet particle deposition, the dry gaseous deposition is essential for realistic prediction of PCDD/F depositions to soil, especially for tetra- and penta-chlorinated dioxins.

Heterogeneous UV/Fenton catalytic degradation of wastewater containing phenol with Fe-Cu-Mn-Y catalyst

The heterogeneous UV/Fenton process with the appropriate amount of Fe-Mn-Cu-Y as catalyst was developed and various operation conditions for the degradation of phenol were evaluated. The results indicated that by using the heterogeneous UV/Fenton process, the CODcr removal rate reached almost 100% for wastewater containing phenol. Compared with the homogeneous process, the developed catalyst could be used at wider pH range in the UV/Fenton process. Comparison of various heterogeneous process showed that heterogeneous UV/Fenton process was best. The heterogeneous UV/Fenton process with Fe-Mn-Cu-Y catalyst is highly efficient in degrading various organic pollutants.

Impact of individual acid flue gas components on mercury capture by heat-treated activated carbon

Elemental mercury capture on heat-treated activated carbon (TAC) was studied using a laboratory-scale fixed bed reactor. The capability of TAC to perform Hg⁰ capture under both N₂ and baseline gas atmospheres was studied and the effects of common acid gas constituents were evaluated individually to avoid complications resulting from the coexistence of multiple components. The results suggest that surface functional groups (SFGs) on activated carbon (AC) are vital to Hg⁰ capture in the absence of acid gases. Meanwhile, the presence of acid gas components coupled with defective graphitic lattices on TAC plays an important role in effective Hg⁰ capture. The presence of HCl, NO₂, and NO individually in basic gases markedly enhances Hg⁰ capture on TAC due to the heterogeneous oxidation of Hg⁰ on acidic sites created on the carbon surface and catalysis by the defective graphitic lattices on TAC. Similarly, the presence of SO₂ improves Hg⁰ capture by about 20%. This improvement likely results from the deposition of sulfur groups on the AC surface and oxidation of the elemental mercury by SO₂ due to catalysis on the carbon surface. Furthermore, O₂ exhibits a synergistic effect on Hg⁰ oxidation and capture when acid gases are present in the flue gases.
