Industrial Convergence of Marine Ranching and Offshore Wind Power:Concept and Prospect

China is a major maritime country. The booming marine ranching and offshore wind power industries are becoming important components of Chinese marine economy. The industrial convergence of marine ranching and offshore wind power is a representative innovation of modern high-efficiency agriculture industry and new energy industry, which plays a great significant role in accelerating the shift in driving forces for economic development. Nonetheless, such a program has not yet been established in China now. In this paper, current advances of marine ranching and offshore wind power industries are discussed. Then the necessity, concept,prospects, scientific problems, technological difficulties, and research contents of industrial convergence are presented in detail. The focus of such study is to provide new insights on how to build the new model of modern marine ranching with the purpose of realizing sustainable fishery output and clean energy production

用高速阴影技术研究K9玻璃中的失效波

用高速阴影摄影技术研究了爆轰加载下K9玻璃样品中波的传播和压缩区内损伤破坏的物理图象和规律。实验中观测到冲击波阵面后有一个移动速度为2.1mm/μs～2.2mm/μs的黑色阴影区边界，即失效波(Failure wave)；实验发现只有当冲击载荷接近材料的HEL时，在冲击波 和失效波之间的区域才有少量的微裂纹成核和长大，而在冲击载荷较低时却没有观察到；同时实验中观测到失效波萌生于被撞击面，并在两块玻璃的交界面上观测到失效波的再生。这些结果表明失效波的产生基本与冲击相变无关，主要与玻璃样品表面的初始损伤有关

On the strategies and approaches of high-quality development of coastal ecological farm and ranch in the Yellow River Delta

The Yellow River Delta is rich in natural resources and has a unique ecosystem.The ecological protection and high-quality development in the Yellow River Delta have become a national strategy.Under the severe constraints of resources and environments as well as the serious degradation of ecosystems,the ecological protection and high-quality development of the Yellow River Delta urgently need the guidance and support of scientific and technological innovation.The implementation of coastal ecological farm and ranch is considered to be one of the important ways to achieve high-quality development.In order to create new models of green,low-carbon and circular coastal ecological farm and ranch in the Yellow River Delta,this paper analyzed the existing problems in coastal ecological farm and ranch,and put forward the high-quality developmental concepts and targets.At present,the unoptimized macroscopical planning,the incomplete industrial system,the imperfect innovation system,and the unstrengthened policy support of coastal ecological farm and ranch have restricted the high-quality development of coastal ecological farm and ranch in the Yellow River Delta.Furthermore,multi-driven high quality development approaches were raised as follows.Firstly,optimizing the macroscopical planning driven by watersalt scenario,that is,identify the complexity of the water-salt scenario and plan the layout reasonably;analyze the dynamics of the water-salt scenario and accomplish digital management.Secondly,highlighting the chip function driven by seed industry,that is,improve biodiversity based on native species protection;strengthen the cultivation of improved seed to enhance the driving force of industry;promote seed breeding to improve the coverage of seed industry.Thirdly,promoting model innovation driven by farm-aquaculture interaction,that is,connect land and sea to optimize industrial spatial layout;integrate farm and ranch,and establish linkage between Three Industries.Fourthly,realizing the intelligent upgrading of industry driven by equipment development,that is,build unmanned farms in saline and alkaline land;realize less populated farms and ranches on the tidal-flat area;create shallow sea intelligent ranches.Fifthly,innovating the collaborative paradigm driven by research-industry linkage,that is,integrate innovative elements to solve the problem of disconnection between industry and scientific research;financing through multiple channels to enhance innovation vitality.Finally,achieving industrial upgrading driven by governance policy,that is,integrate research and development resources and improve innovation ability;implement integrated development and strengthen the whole industrial chain;forward-looking layout of special research projects and innovative development modes.Therefore,stakeholders could construct new developmental models of coastal ecological farm and ranch in the Yellow River Delta with match of water-salt scenarios,integration of farm and ranch,and linkage of Three Industries,to realize the coordinated development of mechanization,intelligence,digitization and systematization.Our study is helpful to provide a reference for the high-quality development of coastal ecological farm and ranch in the Yellow River Delta

ultrasensitivedetectionofhaircortisolbasedonportableramanspectrometeranddoublelayerpapermicrodevice

Cortisol in the human hair is a clinical biomarker of long-term social-and-work-related mental stress, which is of high morbidity rate in the current modern society. This study developed a sensitive hair cortisol assay, featuring surface- enhanced Raman spectroscopy, immunoreaction, and a double-layer paper microdevice. The first layer of the paper microdevice was used to remove the hair residue in the hair extract by filtration (sample pretreatment). The second layer was used for competitive immunoreaction and detection. Standard cortisol antigen immobilized in the second layer and the free cortisol in hair extract competed to bind the spiked Raman-active cortisol monoclonal antibody solution. The hair cortisol can be quantitated by the intensity of Raman signal of monoclonal antibody bound on the paper. We found the Raman signal decreased as the cortisol concentration increases in hair samples. The relative Raman intensity measured was linearly proportional to the logarithmic value of the cortisol concentration in hair samples we measured. The detection of limit (LOD) was 1 pg/mL with the portable Raman spectrometer. The RSD of measurement was 8.38% (n=6). In addition, we used LC-MS to measure two real samples as a comparison with our method as above. The results are 0.771 and 0.153 ng/mL by LC-MS method and 0.63 and 0.247 ng/mL by the proposed method. It can be observed that the results are in same order, demonstrating the validity of the proposed method. In addition, 48 samples can be measured in a single chip. These results showed that this method is sensitive, specific, and suitable for large-scale screening of hair cortisol samples
