The influence of heterogeneous environmental regulation on the green development of the mining industry: empirical analysis based on the system GMM and dynamic panel data model

The intensity of environmental regulation (ERI) affects the short-term effect of the level of green mining (GML), and which structure determines the long-term mechanism. Based on the panel data from 2001 to 2015, with the dynamic panel model and system GMM estimation method were employed to test the influence of heterogeneous environmental regulation on green mining and its transmission mechanism. The results show that, there is a “U” type nonlinear relationship between the ERI and GML. The direct effect of command-control-based (CAC) and the market incentive-based (MBI) environmental regulation on green development of mining shows the characteristics of inhibition and promotion. There is a “U” type of indirectly moderating effect between technological innovation and the energy consumption structure on the GML. The technological innovation promotes the green development of the mining industry only after pass the inflection point of MBI, while the CAC plays a significant guiding role in upgrading of the energy consumption structure. There is an inhibition and promotion effect of MBI on the GML in the southeast coastal area, and the CAC is not significantly. Meanwhile, both of the ERI shows no positive effects in the central and western inland region.

泥磷液相催化氧化氮氧化物

采用磷化工行业的固体废物泥磷液相催化氧化氮氧化物。实验结果表明,该方法是可行且有效的。随着温度的升高,泥磷吸收液的脱硝效率提高,当温度达到泥磷熔点时脱硝效率最佳。泥磷吸收液的脱硝效率随固液比的增大而有所下降,而随着NO体积分数和气体流量的增大,泥磷吸收液的脱硝效率呈先升后降的趋势。各因素对脱硝率的影响大小顺序为：气体流量>反应温度>固液比>NO体积分数。在反应温度60 ℃、固液比1∶4、NO体积分数0.03%、气体流量0.3 L/min的最佳工艺条件下,反应160 min的平均脱硝率可达97.38%。     

A bibliometric analysis of biodiesel research during 1991–2015

A bibliometric analysis based on the Science Citation Index Expanded (SCI-EXPANDED) from the Web of Science was carried out to provide insights into research activities and tendencies of the global biodiesel from 1991 to 2015. The document type and language, characteristics of publication outputs, Web of Science categories, journals, countries, institutions, author keyword and most cited articles were emphasized. The results indicated that annual output of the related scientific articles increased steadily. The top six categories focus on different aspects of biodiesel research. Bioresource Technology and Fuel were the two most frequent journals in the field of biodiesel research. The USA took a leading position and had the highest h-index (108) out of 122 countries/territories, followed by China and Brazil. Finally, author keywords and most cited articles were analyzed, indicating that microalgae, Jatropha curcas, vegetable oil and waste cooking oil are the most general raw materials for biodiesel production.     

A Novel Eco-friendly Blood Meal-based Bio-adhesive: Preparation and Performance

In this reported study, a renewable and eco-friendly blood meal-based (BM) bio-adhesive was developed for the plywood fabrication. Polyvinyl alcohol (PVA), sodium dodecyl sulphate (SDS), and triglycidylamine (TGA) were respectively employed as emulsifier, denaturant and crosslinking agent to modify the BM adhesive. Three-ply plywood was manufactured and its wet shear strength was tested. The solid content, residual rate, functional groups, thermal degradation behavior, and cross section micromorphology of the resulting adhesives were characterized in detail. The experimental results showed that PVA prevented the BM agglomeration, SDS unfolded the structure of protein and then TGA reacted with the exposed active groups in the BM protein molecules, forming a cross-linked structure. As a result, the thermal stability of the modified BM adhesive was improved and the cross section of the cured adhesive was more homogeneous, which enhanced the performance of the adhesive. Consequently, the wet shear strength of the plywood bonded by modified BM adhesive markedly increased by 388% to 1.27 MPa. Compared with soy bean meal-based adhesive, a higher protein content and hydrophobic amino acids content of BM are benefit for fabricating high performance bio-based adhesive, which rendered the BM adhesive practical for plywood industrial application.     

The effect of plasma components on hemoglobin release test in red blood cells (RBC)

Electrophoresis release test (ERT) was established by our lab to observe the re-released hemoglobin (Hb) from red blood cells (RBCs) and whole blood. In this study, ERT was performed to study the effects of different plasma components including plasma, serum, albumin, globulin, fibrinogen, glucose, amino acid, vitamin, insulin, hormone, and inorganic ions on re-released Hb from RBC and whole blood samples during ERT. The results showed that plasma, serum, albumin, globulin, compound amino acid, essential amino acid, vitamin C, insulin, hormone, NaCl, KCl, CaCl₂, and NaHCO₃^? decreased re-released RBC Hb; while glucose, vitamin B1, vitamin B2, and vitamin B12 elevated re-released RBC Hb. The differing effects of various plasma components on re-released Hb of RBC may play a significant role in blood conservation.
