制革工业产生了大量的固体和液体形式的废弃物，如高浓度的有机物、盐和重金属（铬化合物），其环境影响一般来说都非常大。为了使制革工业与目前的环境思维更加吻合，人们设计出了各种各样的方法来减少其环境影响。本研究对生皮的脱毛-浸灰方法进行了改进，减少了化学药品的用量，再装料后，将脱毛-浸灰液重新利用几次。因此，本研究的目的就是为了降低脱毛-浸灰工序的经济和环境成本。实验室规模的试验采用了一个为此目的而设计的模拟设备。使用生命周期评价对这种改进方法的环境净利益进行了评价，而该方法的经济可行性则采用现值法进行评价。所产皮革的质量由来自制革行业的专家（制革者）进行评价。在环境方面，当脱毛-浸灰工序的水被循环利用4次时，这种改性方法使环境影响降低24％，COD减少50％，硫化物减少73％。与传统的方法相比，这种改性方法需要在新设备方面进行一些投资，其劳动强度要大一些，但是，却可以节约58％的水和28％的化工材料，并且可以减少58％的废水处理成本。这种改性方法允许重新使用脱毛-浸灰液4次，而对成品革的质量没有明显的影响。可以肯定的是，与传统方法相比，这种改性方法降低了脱毛-浸灰工序的经济和环境成本。

浅水域水下辐射噪声传播会受到海面与海底反射的影响。基于传统单水听器方法进行浅水域船舶水下辐射噪声源级测量相比深水域测量面临三个问题:(1)浅水域声场中复杂的声场分布特征会增加单水听器测量结果的不确定度;(2)浅水域传播损失系数小于深水域,采用球面波衰减系数进行源级修正会带来较大偏差;(3)水听器近水面布放会导致测量结果受到水面镜像反射的影响比深水域更大。本文提出一种工程化的基于多距离声阵实测传播损失的浅水域船舶水下辐射噪声源级推算方法,在浅水域测量船舶水下辐射噪声源级时剥离界面反射的影响,得到自由场环境下船舶水下辐射噪声源特性。利用不少于3个正横距离分析该海域的传播损失系数,并提出剥离水面劳埃德镜像效应的修正公式。为了验证该方法的有效性,使用UW350声源模拟船舶噪声源在千岛湖开展验证试验,试验结果表明,在20 Hz~1 kHz频段内,推算得到的声源级频谱与1m处参考水听器测量声压级频谱平均偏差小于3 dB。

Continued Successful sa Recovery during the Maintenance Stage: Intra-Individual Resource Loss &Gain Predict Relapse

引用

Open Journal of Medical Psychology 2012年第1期1卷 1-7页

作者： Lisa C. Walt ed Stevens Leonard A. jason Joseph R. Ferrari DePaul University.

Objectives: We combine Hobfoll’s Conservation of Resources (COR) theory and key components of self-help group “step work” ideology to investigate how dynamic changes in key intra-individual resource loss and gains (self-esteem, abstinence self-efficacy, existential growth) influence relapse rates in a sample of individuals in the Maintenance Stage of substance abuse recovery. Methods: Participants (n = 579) completed two surveys over a nine month period that assessed baseline and changes in intra-individual loss and gain resources as well as relapse rates over study course. Multiple regression analyses were performed to predict whether baseline and dynamic changes in intra-individual scores predict relapse rates over time. Results: Individuals that reported lower levels of resource gain at baseline, as well as decreased gain trajectories and increased loss trajectories over time were more likely to relapse. Conclusions: Findings support self-help group “step work” models and the application of COR theory for relapse likelihood prediction in a sample of individuals in longer term substance abuse recovery. Research efforts should examine the complex relationship between these dynamic intra-individual resources, social cognition, self-regulation and relapse risk. Future interventions should address the importance of the continual development and protection of these valuable intra-individual resources to prevent relapse.

通过对近年大学生思想政治教育论文的分析和研究,我们可以看出关于大学生思想政治教育的研究发展迅速,研究内容紧跟时代步伐。学者们认真思考社会实践中产生的各种新问题,他们的研究凸现了思想政治教育的功能。但是近年的研究关注宏观问题的研究比较多,对大学生思想政治教育的个案和案例研究较少。另外,关于大学生思想政治教育研究的话语体系和创新研究的质量等还值得研究者们继续努力和探索。

Optimization of PCR-SSCP Reaction System and Reaction Conditions in Crataegus spp.

引用

Agricultural Science & Technology 2017年第3期18卷 398-401页

作者：撒云俐那冬晨山西师范大学生命科学学院山西临汾041000

[Objective] This study was conducted to optimize PCR-SSCP reaction system and conditions for hawthorn （Crataegus spp.）. [Method] The chloroplast DNA and nuclear DNA of hawthorn leaf were extracted with improved CTAB method. Pdmers for the PCR amplification of chloroplast DNA and nuclear DNA were select- ed from eight pairs of candidate pdmers, and the PCR-SSCP reaction system and reaction conditions were optimized. The PCR products were detected by agarose gel electrophoresis, and the denatured PCR-SSCP products were analyzed by native polyacrylamide gel. [Result] Five pairs primers （psbA-tmH, ropB, ropL, rpoC1 and ITS2） were proved to be suitable for PCR-SSCP in hawthorn, including four for chloroplast DNA and one for nuclear DNA. The clear electrophoretogram of PCR- SSCP in hawthorn was obtained by performing electrophoresis in 0.5×TBE buffer, at 4 ℃ and 200 V for 3-4 h, using 6% native polyacrylamide gel （crosslinking ratio at 29：1）, and the PCR product had been mixed with an equal volume of loading buffer containing 1% NaOH （without glycerol） and denatured at 98℃ for 15 min. [Conclu- sion] The results may lay the foundation of SSCP analysis of hawthom.
