Journal of Environmental Sciences 2003年第2期15卷 241-248页

作者： chun-yen-chang (Department of Horticulture, “National chung Hsing University”, Taichung, Taiwan, China) Department of Horticulture National Gung Hsing University Taichung Taiwan Republic of China.

This study tries to discuss the relationship between landscape structure and organisms in the perspective of landscape architecture. The research hypotheses were then proposed as (1) there are relationships between landscape structure indexes and birds' diversity in the rural areas of Taiwan; (2) the relationships between landscape structure and birds' diversity will be different in different hierarchical levels. In order to increase the bird species, landscape planners could tries to increase the density of water bodies, but decrease the farms and human planted woods. Decrease the density of constructed and human planted grasslands. Increase the area of un-worked acres, natural grasslands, and the area of water bodies and circular the water bodies and natural forest. In order to increase birds' diversity, landscape planners could decrease the concentration of paved areas. Concentrate the human planted trees to increase the core areas of woodlands. Increase the area of natural grassland circular. In order to increase the total number of birds in the planning areas, landscape planners could scattered the paved areas and lengthen the constructed areas. Decreases the core region of the constructed areas. Increase the area of un-worked acres and water bodies. Decrease the disturbance of both the interior area of natural and human planted woodlands and try to increase the density of water bodies.;The analysis results showed that the small grain size indexes are more suitable for the rural areas of Taiwan to capture the influential factors of bird communities. The high fragmentation of land usages in Taiwan lessens the influences of the regional landscape pattern.

Chinese Journal of Biomedical Engineering 2024年第02期33卷 85-92页

作者： ZHONG chang-rui FU chun-hua Longyan First Affiliated Hospital of Fujian Medical University The Second Hospital of Longyan

Objective: To explore the effect of platelet-rich plasma(RPR) in stimulating the transformation of pro-inflammatory(M1) macrophages into antiinflammatory(M2) under the adenosine-monophosphate-dependent protein kinase(AMPK) signaling pathway. Methods: Rat peritoneal macrophages(RAW264.7) were cultured and randomly divided into 8 groups: blank control group, LPS group, RPR group A, RPR group B, LPS+RPR(12 h) group, LPS+RPR(24 h) group A, LPS+RPR(24 h)group B, LPS+RPR(24 h) group C. RPR was prepared based on blood donors. The expressions of AMPK signaling pathway-related proteins(AMPK, ULK1, m TOR) and macrophage markers(i NOS, Arg-1) in the blank control group, LPS group, LPS+RPR(12 h)group and LPS+RPR(24 h) group were observed and compared. The expressions of macrophage markers in LPS+RPR(24 h) B and C groups were compared, and the expressions of AMPK and TGF-β in RPR A and B groups were compared. Results: The gray values of AMPK and ULK1 in LPS cells decreased significantly, while those in LPS+RPR(12 h) and LPS+RPR(24 h) A cells increased significantly. The gray values of AMPK and ULK1 in LPS+RPR(24 h) A cells were higher than those in LPS+RPR(12 h)cells(P<0.05). The m TOR gray value of LPS cells was significantly higher than that of LPS+RPR(24 h) A cells, and the m TOR gray value of LPS+RPR(24 h) A cells was significantly lower than that of LPS+RPR(12 h) cells(P<0.05). The expression of i NOS in LPS cells was significantly decreased, the expression of i NOS in LPS+RPR(12 h) and LPS+RPR(24 h) cells was significantly increased, and the expression of i NOS in LPS+RPR(24 h) cells was higher than that in LPS+RPR(12 h) cells(P<0.05). The expression of Arg-1 in LPS cells was significantly decreased, the expression of Arg-1 in LPS+RPR(12 h) and LPS+RPR(24 h) A cells was significantly increased, and the expression of Arg-1 in LPS+RPR(24 h) A cells was higher than that in LPS+RPR(12 h)cells(P<0.05). The i NOS expression level of LPS+PRP(24 h) C cells was significantly higher

One-step conversion of methane and formaldehyde to ethanol over SA-FLP dual-active-site catalysts: A DFT study

Chinese Chemical Letters 2024年第4期35卷 544-548页

作者： Tao Ban Xi-Yang Yu Hai-Kuo Tian Zheng-Qing Huang chun-Ran chang Shaanxi Key Laboratory of Energy Chemical Process Intensification School of Chemical Engineering and TechnologyXi'an Jiaotong UniversityXi'an 710049China Shaanxi Key Laboratory of Low Metamorphic Coal Clean Utilization School of Chemistry and Chemical EngineeringYulin UniversityYulin 719000China

One-step conversion of methane and formaldehyde into ethanol is a 100% atom-efficient process for carbon resources utilization and environment protection but still faces eminent challenges due to the lacking of efficient catalysts. Therefore, developing active and stable catalysts is crucial for the co-conversion of methane and formaldehyde. Herein, twelve kinds of “Single-Atom”-“Frustrated Lewis Pair”(SA-FLP)dual-active-site catalysts are designed for the direct conversion of methane and formaldehyde to ethanol based on density functional theory(DFT) calculations and microkinetic simulations. The results show that the SA-FLP dual active sites can simultaneously activate methane at the SA site and activate formaldehyde at the FLP site. Among the twelve designed SA-FLP catalysts, Fe1-FLP shows the best performance in the co-conversion of methane and formaldehyde to ethanol with the rate-determining barrier of 1.15 e *** is proved as the main product with the turnover frequency of 1.32 × 10^(-4)s^(-1)at 573 K and 3 *** work provides a universal strategy to design dual active sites on metal oxide materials and offers new insights into the effective conversion of methane and formaldehyde to desired C_(2) chemicals.
