In order to remove this contradiction, this phenomenon was studied in depth, theoretically and experimentally, using an experimental setup similar to Faraday’s. Calculations of the induced electromotive force, based on relativity on the one hand and on Faraday’s view on the other were made with the help of measurements of the magnetic field components. Accurate magnetic field measurements are confirmed by analytical calculations. Precise-induced electromotive force measurements confirmed Faraday’s view and contradicted the theory of relativity.展开更多

Acupuncture and moxibustion have been actively involved in combating major epidemics such as malaria, schistosomiasis, and COVID-19. This article conducts a historical review of these three significant cases to elucidate how the acupuncture community has effectively utilized its unique advantages and characteristics through theoretical discussions, clinical practices, experimental research, as well as receiving administrative leadership and political support from the Communist Party of China and government. We provide an objective evaluation of their effectiveness while summarizing historical experiences to serve as a reference for future utilization of acupuncture and moxibustion therapy in epidemic relief efforts. Additionally, propose four suggestions: strengthening Party leadership and enhancing political support;timely summarization of experiences to establish programs and systems;deepening scientific research by integrating experimental findings with clinical practice;focusing on public awareness campaigns and education to solidify grassroots foundations.展开更多

We conclude that it is an indispensible strategy to give priority to the development of urban sectors to promote economic growth and reduce rural poverty, and that the development of low value-added agriculture yields few, if any, benefits in decreasing rural poverty. By first adopting urban-biased policies and promoting industrialization, China has created new sources of economic growth and urban employment opportunities to absorb the surplus rural workforce. Entering labor-intensive industrial sectors for higher incomes has thus become a critical avenue for the rural poor to benefit from economic growth and escape poverty.展开更多

It affects the individuals physically as well as mentally. The advancement in medical knowledge and technology in transplant surgery has steadily increased the number of kidney recipients. This offers hope for the new lease of life and a wide range of perceptions and experiences with self, society and the new organ. There is minimal research on perceptions and lived experiences of kidney transplant recipients. This study explored the perceptions and lived experiences of individuals with a kidney problem living with a kidney transplant in Shanghai, China. Five in-depth interviews were conducted with five clients. The participant’s age ranged from 25 to 45 years. There were three females and two males. Content analysis using NVivo (11.0) software was applied in data analysis. The findings revealed improved quality of life among kidney recipients;however the clients had low knowledge levels on the condition as well as self care practices in the post transplant period. This caused a lot of psychosocial stress in the clients. The post kidney transplant management strategies should include effective education programs to increase awareness on the condition and self care practices so as to reduce factors associated with psychosocial stress in order to improve the quality of life for the clients in the post kidney transplantation period.展开更多

文摘At present,with the steady development of the global economy,more and more countries begin to pay attention to the impact of ecological environment on economic development and human society,so the ecological environment has become a global issue that cannot be ignored in today’s era.Therefore,from the perspective of the ecological philosophy of Diversity&Harmony as well as Interaction&Co-existence,this paper will conduct ecological discourse analysis on the Energy in China’s New Era based on the transitivity system of systemic-functional grammar,and use the Corpus analysis software UAM Corpus Tool 3.3x to label and make statistics on the transitivity system,aiming to explore the distribution characteristics of the transitivity system in this white paper.Through the transitivity analysis of the white paper,this study helps readers to have a deeper understanding of the positive significance contained in the white paper.To a certain extent,it enables readers at home and abroad to understand China’s stance on energy issues and the positive image of China in energy ecology.It also awaken readers’awareness of environmental protection and acquire good habits of resource conservation to be in harmony between human and nature for sustainable development.
文摘When studying the phenomenon of the induced electromotive force, which originates from Faraday’s unipolar inductor, the contrast between Faraday’s view of the magnetic field dynamic lines and the theory of relativity is revealed. In order to remove this contradiction, this phenomenon was studied in depth, theoretically and experimentally, using an experimental setup similar to Faraday’s. Calculations of the induced electromotive force, based on relativity on the one hand and on Faraday’s view on the other were made with the help of measurements of the magnetic field components. Accurate magnetic field measurements are confirmed by analytical calculations. Precise-induced electromotive force measurements confirmed Faraday’s view and contradicted the theory of relativity.

文摘Since the establishment of the People’s Republic of China, both the Communist Party and the government have placed great emphasis on the advancement of traditional Chinese medicine. Acupuncture and moxibustion have been actively involved in combating major epidemics such as malaria, schistosomiasis, and COVID-19. This article conducts a historical review of these three significant cases to elucidate how the acupuncture community has effectively utilized its unique advantages and characteristics through theoretical discussions, clinical practices, experimental research, as well as receiving administrative leadership and political support from the Communist Party of China and government. We provide an objective evaluation of their effectiveness while summarizing historical experiences to serve as a reference for future utilization of acupuncture and moxibustion therapy in epidemic relief efforts. Additionally, propose four suggestions: strengthening Party leadership and enhancing political support;timely summarization of experiences to establish programs and systems;deepening scientific research by integrating experimental findings with clinical practice;focusing on public awareness campaigns and education to solidify grassroots foundations.

文摘Since the People’s Republic of China founded,especially over the last 15 years,maternal mortality rate(MMR)has fallen dramatically.In 2014,China has achieved the target of a reduction of 75%MMR from 1990 to 2015(MDG 5)ahead of schedule.This achievement can be attributed to the improvement of legislation and policy,government commitment and investment on maternal health,extensive international cooperation,implementation of the maternal health program,development of maternal and child health(MCH)service system and development of MCH surveillance systems.Although China has achieved MDG 5,there are many kinds of difficulties and challenges in achieving the post-2015 Sustainable Development Goals(SDGs).Therefore,multi-strategy actions need to be considered to seize the opportunities to further reduce the MMR in the future.

文摘This paper makes an appraisal of the successful experience of China, a country with the largest agricultural population in the world, in the reduction of rural poverty. We conclude that it is an indispensible strategy to give priority to the development of urban sectors to promote economic growth and reduce rural poverty, and that the development of low value-added agriculture yields few, if any, benefits in decreasing rural poverty. By first adopting urban-biased policies and promoting industrialization, China has created new sources of economic growth and urban employment opportunities to absorb the surplus rural workforce. Entering labor-intensive industrial sectors for higher incomes has thus become a critical avenue for the rural poor to benefit from economic growth and escape poverty.

文摘Terminal kidney disease is a life threatening condition and cause for loss of hope to affected individuals. It affects the individuals physically as well as mentally. The advancement in medical knowledge and technology in transplant surgery has steadily increased the number of kidney recipients. This offers hope for the new lease of life and a wide range of perceptions and experiences with self, society and the new organ. There is minimal research on perceptions and lived experiences of kidney transplant recipients. This study explored the perceptions and lived experiences of individuals with a kidney problem living with a kidney transplant in Shanghai, China. Five in-depth interviews were conducted with five clients. The participant’s age ranged from 25 to 45 years. There were three females and two males. Content analysis using NVivo (11.0) software was applied in data analysis. The findings revealed improved quality of life among kidney recipients;however the clients had low knowledge levels on the condition as well as self care practices in the post transplant period. This caused a lot of psychosocial stress in the clients. The post kidney transplant management strategies should include effective education programs to increase awareness on the condition and self care practices so as to reduce factors associated with psychosocial stress in order to improve the quality of life for the clients in the post kidney transplantation period.
