The performance of the steel scale (SS)-CaO composite on the combustion of coke nuts and in-situ reductionof SO2 and NO emission was investigated. Combustion experiments show that SS-CaO compositeaccelerates coke combustion and reduces SO2 and NO emissions concurrently. X-ray diffraction (XRD),scanning electron microscopy (SEM), and electron spin resonance (ESR) were used to investigate thecatalysis mechanism. Results show that SS and CaO have synergistic effect in in-situ denitration. Theincrease of SS and CaO fraction in the composites improve the denitration and sulfur fixation performance,respectively. The denitration activity is mainly attributed to the Fe2O3 in SS and Ca2Fe2O5 formedduring combustion. The desulfurization is due to the sulfur fixation with CaO. The increasing fraction ofCaO in the composites leads to the agglomeration of ash particles. 2%CaO is confirmed as the optimumaddition for catalytic combustion and emission reduction. This work sheds light on the cheap and effectivecatalysts that are potentially useful for iron ore sintering.

A RIF Based Mapping of RDB2RDF

Ying Chen,Zhuoming Xu,Yuyan Ni,Guangxu Cao,Shiqing Zhang 보안공학연구지원센터 2014 International Journal of Database Theory and Appli Vol.7 No.6

Mapping RDB to RDF (i.e., RDB2RDF) is the key to constructing the Semantic Web, hence has been an active research field during the last decade. Many technically heterogeneous RDB2RDF tools resulted in non-interchangeable and unreusable RDB2RDF mapping descriptions. In 2009, the W3C RDB2RDF Incubator Group Report once strongly suggested that the RDB2RDF mapping language be expressed in rules as defined by the W3C Rule Interchange Format (RIF) Working Group, because rules are an effective way to express mappings between information models, and RIF, as part of the infrastructure for the Semantic Web, is now a standard for exchanging rules among Web rule systems. This paper addresses the issue of RIF-based RDB2RDF mapping and proposes a database semantics-driven, RIF Production Rule Dialect (RIF-PRD) based mapping description approach. The work includes defining a set of generic RIF-PRD mapping rules for RDB2RDF, developing a prototype mapping engine called RIFD2RME (stands for RIF-based RDB2RDF Mapping Engine), and conducting case study experiments with the prototype. The experimental results indicate that the proposed mapping approach is achievable and effective.

A kind of core cross-linked ‘‘semi-amphiphilic” polymer assemblies for controlled release of corrosion inhibitors and autonomous corrosion alarm

Ying Cao,Aoqi Zhu,Jianmin He,Jianhua Wu,Mingjin Xue,Yiting Xu,Birong Zeng,Guorong Chen,Lizong Dai 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.115 No.-

A novel kind of core cross-linked assemblies formed from a ‘‘semi-amphiphilic” block copolymer, poly(syringaldehyde methacrylate)-block-poly (dopamine methacrylate-co-methyl methacrylate-costyrene)(PSMA-b-P(DMA-co-MMA-co-St)), was designed and served as the carrier for anti-corrosiveand corrosion detective molecules. Different from the core cross-linked micelles formed by the amphiphilicpolymers in water, the core cross-linked assemblies in this research were formed from the ‘‘semiamphiphilic”block copolymer, which took advantage of the different compatibility between epoxy andthe blocks in the polymer, leading to the self-assembly behavior happening in the organic resin, whilethey shared the advantages of traditional core cross-linked micelles with the properties of being stable,stimuli-responsive and multifunctional. The pH-responsive properties of the assemblies and their complexationwith Fe3+ caused by the corrosion of the steel were confirmed by UV spectrophotometry andXPS analysis of the corrosive products. The controlled release of corrosion inhibitors was fully reflectedby the expansion of the capacitor ring and the increase of the coating resistance (Rc) with the extensionof the immersion time, which was got via fitting the electrochemical impedance spectroscopy (EIS) datawith the equivalent electric circuits. Ultimately, the anti-corrosive mechanism of smart coating with thefunctional core cross-linked assemblies were also illustrated.

The intestinal barrier function disrupted in sepsis, while little is known about the variation in different phases of sepsis. In this study, mouse models of sepsis were established by caecal ligation and puncture (CLP). The H&E staining of sections and serum diamine oxidase concentration were evaluated at different timepoint af-ter CLP. TUNEL assay and EdU staining were performed to evaluate the apoptosis and proliferation of intestinal epithelium. Relative protein expression was assessed by Western blotting and serum concentrations of pro-inflammatory cytokines was mea-sured by ELISA. The disruption of intestinal barrier worsened in the first 24 h after the onset of sepsis and gradually recovered over the next 24 h. The percentage of apop-totic cell increased in the first 24 h and dropped at 48 h, accompanied with the prolif-erative rate of intestinal epithelium inhibited in the first 6 h and regained in the later period. Furthermore, the activity of nuclear factor kappa B (NF-κB) presented similar trend with the intestinal barrier function, shared positive correction with apoptosis of intestinal epithelium. These findings reveal the conversion process of intestinal barrier function in sepsis and this process is closely correlated with the activity of NF-κB signaling.

Peng Cao,Lan-Ying Liu,Xue-Ting Cai,Xiao-Ning Wang,Jie-Ge Huo,Zhong-Ying Zhou 셀메드 세포교정의약학회 2012 셀메드 (CellMed) Vol.2 No.2

Fever in cancer patients is often due to the following causes: evil qi and toxity stagnancy, disorders of qi and blood, deficiencies of zang and fu organs, and the disorder of yin and yang. The treatments given to cancer patients with a fever are according to five: (a) Excessive inner heat and toxicants: remove heat and the toxicant, induce purgation. We use Cheng-Qi-Tang plus Qing-Wen-Bai-Du-Yin. (b) Tangle of damp and heat, and qi stagnancy: remove damp and heat, smooth the qi channel. We use Gan-Lu-Xiao-Du-Dan or San-Ren-Tang. (c) Obvious blood and heat stagnancy: remove heat and blood stasis. We use Xue-Fu-Zhu-Yu-Tang. (d) Deficiency of spleen qi, inner heat caused by a yin deficiency: nourish spleen qi and yin to remove the inner heat. We use Bu-Zhong-Yi-Qi-Tang or Xiao-Jian-Zhong-Tang. (e) Prominent yin deficiency and hectic fever: replenish yin and remove inner heat. We use Qing-Hao-Bie-Jia-Tang or Chai-Qian-Mei-Lian-San. The pathogenesis of fever in cancer patients is complicated. We can see both deficiency and excess in one differentiation. Therefore, we must make sure of it, then we can get the most effective treatment.

An Agricultural Land Contractual Management Transfer Prediction Model Based on Analytic Hierarchy Process and Logistic Regression

Hai-ying Cao,Ling Wu 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.10

In the field of application prediction, there are two kinds of common methods to establish the prediction model: prediction model established by artificial data analysis relying on expert experience, and prediction model achieved by statistical model exploiting data analysis. However, the prediction accuracy of the model based on expert is restricted by the experiences, while the model based on statistical analysis is limited by the quality and scale of the training data. In view of the advantages and disadvantages of these two kinds of models, this paper presents a prediction model by integrating Analytic Hierarchy Process and Logistic Regression. The proposed prediction model uses the Analytic Hierarchy Process, which are based on the training data and expert experience to obtain the rank of predominant factor in a specific domain, and exploits the logistical regression model to learn the weights of each influencing factor. Finally, the linear combination of the two models is used to obtain the prediction model. Further, we take agricultural land contractual management transfer prediction as an example to test the proposed hybrid prediction model.

Flexural Behavior of Anchor Horizontal Boundary Element in Steel Plate Shear Wall

Ying Qin,JinYu Lu,Li-Cheng-Xi Huang,Shi Cao 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.3

Steel plate shear walls (SPSWs) have been increasingly used in lateral load resisting system since the post-buckling strength of web plates was realized and considered in practical design. Diagonal tension field is formed in the web plate to resist the lateral force induced by winds and earthquakes. The force is anchored by the surrounded horizontal boundary elements (HBEs) and vertical boundary elements (VBEs) and eventually transferred to the ground. Therefore, the response of HBEs, especially anchor HBEs, is essential to ensure that SPSWs could exhibit the required strength, ductility, and energy dissipation capacity. This paper presents the results of theoretical studies into the flexural behavior of the anchor HBEs of SPSWs and can be regarded as an extension to the previous work by Qu and Bruneau (2011) and Qin et al. (2017). The boundary effect was considered to reflect the actual stress state at the HBE-to-VBE connection, which assembled the method by Qin et al. (2017). Furthermore, more proper distributions of the vertical component of tension field for the positive and negative flexure cases, respectively, were proposed comparing to the work by Qu and Bruneau (2011). The hand calculation approach for the plastic flexural capacity of the anchor HBEs was given by the summation of the contributions from the flanges and the web. The developed equations are compared with previous data and good agreement was found between them. Meanwhile, comprehensively discussions are conducted to evaluate the influence of key parameters on the flexural behavior of anchor HBE. It was found that the plastic flexural capacity of anchor HBE decreases from unity to the minimum as a result of the increase in shear force, axial force and vertical stresses. Moreover, the flexural response of anchor HBE is most vulnerable to the change in shear force. This indicates that boundary effect is significantly important and cannot be ignored in the analysis. The research in this paper provides basis for the capacity design of anchor HBE.

Transcriptome-wide characterization of the WRKY family genes in Lonicera macranthoides and the role of LmWRKY16 in plant senescence

Cao Zhengyan,Wu Peiyin,Gao Hongmei,Xia Ning,Jiang Ying,Tang Ning,Liu Guohua,Chen Zexiong 한국유전학회 2022 Genes & Genomics Vol.44 No.2

Background: Lonicera macranthoides is an important woody plant with high medicinal values widely cultivated in southern China. WRKY, one of the largest transcription factor families, participates in plant development, senescence, and stress responses. However, a comprehensive study of the WRKY family in L. macranthoides hasn't been reported previously. Objective: To establish an extensive overview of the WRKY family in L. macranthoides and identify senescence-responsive members of LmWRKYs. Methods: RNA-Seq and phylogenetic analysis were employed to identify the LmWRKYs and their evolutionary relationships. Quantitative real-time (qRT-PCR) and transgenic technology was utilized to investigate the roles of LmWRKYs in response to developmental-, cold-, and ethylene-induced senescence. Results: A total of 61 LmWRKY genes with a highly conserved motif WRKYGQK were identified. Phylogenetic analysis of LmWRKYs together with their orthologs from Arabidopsis classified them into three groups, with the number of 15, 39, and 7, respectively. 17 LmWRKYs were identified to be differentially expressed between young and aging leaves by RNA-Seq. Further qRT-PCR analysis showed 15 and 5 LmWRKY genes were significantly induced responding to tissue senescence in leaves and stems, respectively. What's more, five LmWRKYs, including LmWRKY4, LmWRKY5, LmWRKY6, LmWRKY11, and LmWRKY16 were dramatically upregulated under cold and ethylene treatment in both leaves and stems, indicating their involvements commonly in developmental- and stress-induced senescence. In addition, function analysis revealed LmWRKY16, a homolog of AtWRKY75, can accelerate plant senescence, as evidenced by leaf yellowing during reproductive growth in LmWRKY16-overexpressing tobaccos. Conclusion: The results lay the foundation for molecular characterization of LmWRKYs in plant senescence.
