The present study aimed to explore the association between parent-children relationship and internet addiction with the mediating effect of self-concept among Chinese adolescents. The Chinese Parent-Children Relationship Diagnostic Test, the Chinese revised edition of Tennessee Self-concept Scale, and the Chinese Internet Addiction Scale were administered to 300 junior and high school students aged 13-18 years (in grades 7-12). Results indicated that parent-children relationship was positively related to self-concept and was negatively related to internet addiction, while self-concept was negatively related to internet addiction among adolescents. Moreover, the association between parent-children relationship and internet addiction was partially mediated by self-concept. Findings of the present study suggested that parent-children relationship exerted not only direct effect but also indirect effect on internet addiction through self-concept. Limitations of the study are considered and implications of the findings for reducing adolescents' internet addiction are discussed., Author(s): Simin Huang [sup.1] , Yaqi Hu [sup.1] , Qing Ni [sup.1] , Yi Qin [sup.1] , Wei Lü [sup.1] Author Affiliations: (1) grid.412498.2, 0000 0004 1759 8395, Shaanxi Key [...]

As a benchmark triple‐conducting cathode, BaCo0.4Fe0.4Zr0.1Y0.1O3−δ (BCFZY) has been widely investigated for protonic ceramic fuel cells (PCFC) in recent years. However, the reported electrochemical performance of BCFZY cathode differs, which is determined in this work to originate from the thermal expansion mismatch between BCFZY and electrolyte. Accordingly, two strategies for enhanced thermo‐mechanical compatibility are examined: impregnation and thermal expansion offset. In contrast to the impregnation of BCFZY nanoparticles on electrolyte backbones that only helps improve electrochemical performance, negative thermal expansion oxide Sm0.85Cu0.15MnO3−δ (SCM)‐offset BCFZY exhibits superior durability and activity simultaneously. Specifically, the polarization resistance decay rate of the SCM‐offset BCFZY is only ~0.2%/100 h, compared with ~18.75%/100 h for "impregnated BCFZY." Moreover, pure SCM generates moderate cathodic performance (area‐specific resistance = 0.11 Ω cm2, 700 °C), X‐ray diffraction and transmission electron microscopy reveal an in‐situ formed intergranular Ba2Cu3SmO7−δ phase at the boundaries of BCFZY and SCM. Thus, SCM can serve as a "three‐effect" additive, i) offset thermo‐expansion, ii) strengthen electrode structure and adhesion, and iii) provide acceptable oxygen‐reduction‐reaction activity, being favorable for superior performance. A PCFC using a SCM‐offset BCFZY cathode achieves the highest power density (1455 mW cm−2) yet recorded for PCFCs with BCFZY‐based cathodes. [ABSTRACT FROM AUTHOR]

Consumptive thirst such as dry mouth and polydipsia, frequent urination polyuria, fear of heat and hyperhidrosis and loss of other body fluids, yin deficiency and internal heat expression, and irritability and other abnormal emotional symptoms are common. The Synopsis of Golden Chamber need to be further explored for the treatment of miscellaneous diseases. The dialectical thought has a high clinical application value. Lily disease treatment recommendations in the Synopsis of Golden Chamber are explored. The symptoms of lily disease are varied and uncertain, which are caused by the scattering and wandering aimlessly of heat pathogen. The pathogenesis of lily disease can be examined through external symptoms such as bitter taste in mouth, red urine, and faint and rapid pulse. Diabetes is also closely related to yin deficiency and internal heat, and the pathogenesis of the two is similar. Mental symptoms are common characteristics of lily disease and diabetes. The method taken from the Synopsis of Golden Chamber and Baihe-like prescriptions for the treatment of diabetes are effective. By identifying different patterns, symptoms, and indicators, we can select lily bulb, common anemarrhena, rhizome, figwort root, unprocessed rehmannia root, and other drugs to treat diabetes, in order to improve our understanding of lily disease and provide new ideas for diabetes treatment.
