The distributions and relationships of O_2, CO_2, and dimethylsulfide (DMS) in the Changjiang (Yangtze) Estuary and its adjacent waters were investigated in June 2014. In surface water, mean O_2 saturation level, partial pressure of CO_2 (pCO_2), and DMS concentrations (and ranges) were 110% (89%–167%), 374μatm (91–640 μatm), and 8.53 nmol L^(-1) (1.10–27.50 nmol L^(-1)), respectively. The sea-to-air fluxes (and ranges) of DMS and CO_2 were 8.24 μmol m^(-2)d^(-1) (0.26–62.77 μmol m^(-2)d^(-1)), and -4.7 mmol m^(-2)d^(-1) (-110.8-31.7 mmol m^(-2)d^(-1)), respectively. Dissolved O_2 was oversaturated, DMS concentrations were relatively high, and this region served as a sink of atmospheric CO_2. The pCO_2 was significantly and negatively correlated with the O_2 saturation level, while the DMS concentration showed different positive relationships with the O_2 saturation level in different water masses. In vertical profiles, a hypoxic zone existed below 20 m at a longitude of 123?E. The stratification of temperature and salinity caused by the Taiwan Warm Current suppressed seawater exchange between upper and lower layers, resulting in the formation of a hypoxic zone. Oxidative de-composition of organic detritus carried by the Changjiang River Diluted Water (CRDW) consumed abundant O_2 and produced additional CO_2. The DMS concentrations decreased because of low phytoplankton biomass in the hypoxic zone. Strong correlations ap-peared between the O_2 saturation level, pCO_2 and DMS concentrations in vertical profiles. Our results strongly suggested that CRDW played an important role in the distributions and relationships of O_2, CO_2, and DMS.

Plant photosynthetic capacity directly determines crop yield. Light quality regulates photosynthetic capacity. This review discusses plant responses to far-red light from the phenotypic to the molecular level, focusing specifically on the improvement of photosynthetic capacity by adjustment of photosynthetic electron transport and the path of light energy. Far-red light can also regulate leaf angle and increase plant height and leaf area, via expression of associated genes, to capture more light ***, far-red light regulates plant morphology and photosynthetic capacity. Identifying the mechanism of this regulation may lead to increased crop yields.

Journal of Biosciences and Medicines 2023年第10期11卷 142-155页

作者： Yang Dong Yue’e Huang Danli Li Jieru Liao tingting tan Shupiao Yang Donghui Liu Department of Geriatrics Guangzhou First People’s Hospital Guangzhou China The Construction of Sub-Center for National Standardization Organ Rehabilitation Center Guangzhou China

Objective: This study visualizes and analyzes the current status, hotspots, and frontiers of cardiac rehabilitation for patients with Coronary Heart Disease (CHD) over the past decade (2012.01-2022.12), and explores the future development trend and research direction of the CR for CHD patients in China. Methods: Relevant literature was searched, screened and downloaded from the Web of Science (WOS) database, and bibliometric and visualization analyses were performed using CiteSpace VI software. Results: Through the search and screening of related literature, 2443 English articles were finally included. Among them, most of the Chinese publishers were mainly universities and had less connection with each other, while the foreign publishers were mainly universities and medical institutions in the United States and Europe, and had close connection with each other. The research content of Chinese scholars mainly focuses on the assessment of patients’ life and psychological status, as well as the assessment of cardiac function. Foreign research focuses on physical training assessment, disease perception, etc. Conclusion: Through visualizing relevant research with CiteSpace VI software in the form of a knowledge map, the research frontiers and trends in the field of cardiac rehabilitation for coronary heart disease patients in China and abroad can be discovered more intuitively. Compared with foreign research, the development of cardiac rehabilitation for coronary heart disease patients in China is relatively slow and insufficient, and institutions lack cooperation. In the future, China should accelerate the connection between regions in the field of cardiac rehabilitation and develop a cardiac rehabilitation model suitable for coronary heart disease patients in China with its own characteristics.

社区党组织在联动社区治理主体、共同整合社区治理要素、实现社区治理目标的过程中形塑了“联动枢纽”的角色。这种“联动枢纽”角色是在“使命—责任型”政党的根本要求下形成的,同时它以政党体系为基础的组织资源、以地域为范围的空间资源、以情感为支撑的文化资源和以网络为导向的技术资源作为形塑条件。通过对某社区党组织联动其他社区治理主体供给公共服务的案例研究,发现其在具体运行的过程中呈现出主体联动、内容联动和方式联动等特征。这种“联动枢纽”角色能够有效形成社区治理的整体合力,实现核心引领与具体联动的结合,并且根据社区治理情况变化进行动态调适。未来的优化路径在于构建集专业化、规范化、制度化于一体的“联动枢纽”角色,同时搭建常态化联动治理平台,促进治理资源的有效配置。

采用基于密度泛函理论的平面波超软赝势方法对含氧空位单斜相HfO2的电子结构和光学性质进行了计算。计算结果表明,氧空位缺陷的存在使得HfO2带隙中出现了缺陷态,主要由最近邻Hf原子的5d态组成。随后,结合计算的电子态密度分析了氧空位对HfO2材料介电常数和吸收系数的影响。氧空位存在时,在380～220 nm的紫外波段内出现了较弱的吸收峰。
