[en] Highlights: •Structural equation modeling was applied to examine factors affecting acceptance. •Perceived energy supply benefit was the most important factor. •Perceived environmental benefit had a significant, positive effect on acceptance. •Perceived risks negatively influenced acceptance. •Trust was significantly associated with perceived benefits and risks. -- Abstract: A causal model explaining Chinese university students' acceptance of nuclear power was tested. In our model, we hypothesized that perceived energy supply benefits, environmental benefits, and risks are determinants of Chinese university students' acceptance of nuclear power. We further assumed that trust affects perceived energy supply benefits, environmental benefits, and risk perception. In other words, trust indirectly affects acceptance. Structural equation modeling procedure was employed to test the hypothesized model, based on the data collected via a questionnaire survey of Chinese university students (N = 506). Results revealed that acceptance was mainly influenced by perceived energy supply benefits. In addition, perceived environmental benefits also had significantly positive impact on acceptance. Compared to the impact of perceived benefits on acceptance, perceived risks had a significantly smaller negative influence. Furthermore, trust strongly affected perceived energy supply benefits, environmental benefits, and risk perception. Therefore, emphasizing energy supply benefits of nuclear power seems to improve the level of acceptance when communicating to Chinese university students.
[en] Dried seeds of maize were carried by recoverable satellite under space conditions of 175 km to 253 km from sea level. Various ultrastructure changes of maize leave were observed, including plasmolysis, expansion of vacuoles and cell walls, proliferation of plasmodesmata, variations of grana disc and stroma thylakoid, breath of nuclear membranes, increase in number and enlargement of endoplasm reticulum and variations of other endomembranes
[en] Highlights: • Content analysis was applied to analyze media coverage of nuclear power in China. • The media coverage is consistent with the Chinese government's nuclear policies. • Anti-nuclear opinions were rarely published. • Nuclear accidents always attract high media attention. - Abstract: China has vigorously pursued nuclear power and has developed a series of ambitious nuclear power policies in the past several years. To smoothly implement these policies, the Chinese government wants to mobilize public support because a high level of public acceptance helps legitimize these policies. Considering that news media can influence public opinion, we analyzed the content of news articles related to nuclear power in two Chinese mainstream newspapers, The People's Daily and The Guangming Daily, between 2004 and 2013. The results show that the articles in the two newspapers primarily reflected pro-nuclear or informational statements, whereas anti-nuclear opinions were rarely published. Pro-nuclear arguments most often focused on environmental benefits and safety, which have been frequently emphasized in the Chinese government's nuclear power policies. These findings indicate that the mainstream news coverage of nuclear power is highly consistent with the Chinese government's pro-nuclear policies, which suggests that the government had a significant impact on the content reported by the mainstream media in China. Lastly, this study proposes some policy recommendations for nuclear power development in China.
[en] Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of leptomeningeal metastasis from hepatocellular carcinoma. We herein report a case of leptomeningeal metastasis from hepatocellular carcinoma in a 53-year-old woman with concomitant systemic metastases to the lung, bone, brain, kidney, adrenal gland, subcutaneous tissues, and abdominal pelvis. The neurological symptoms of the patient were relieved after treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy. To our knowledge this is the first report of leptomeningeal metastasis from hepatocellular carcinoma confirmed by cytology. Treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy was effective
[en] Highlights: • Wear rate of nitrided HEAs was lower than that of as-cast HEAs in the same condition. • The wear mechanism of as-cast alloys in air was abrasive wear of oxide particles. • The wear mechanism of the nitrided HEAs in air was adhesive wear and abrasive wear. • The wear mechanism of HEAs in acid rain was abrasive, oxidative and corrosive wear. • The lubrication action of deionized water and acid rain led to the lower wear rate.
