A shock-timing experiment plays an important role in inertial confinement fusion studies,and the timing of multiple shock waves is crucial to the performance of inertial confinement fusion ignition *** present an experimental observation of a shock wave driven by a two-step radiation pulse in a polystyrene *** experiment is carried out at Shen Guang III Yuan Xing(SGIIIYX)laser facility in China,and the generation and coalescence of the two shock waves,originating from each of the two radiation steps,is clearly seen with two velocity *** two-shock-wave coalescence is also simulated by the radioactive hydrodynamic code of a multi-1D *** experimental measurements are compared with the simulations and quite good agreements are found,with relatively small discrepancies in shock timing.

Production and storage-transportation of crude oil can not only give rise to soil pollution but also destroy ecological environment. Degradation of microbes for oily soil was studied with the instnunent, Geofina Hydrocarbon Meter (GHM), by experimental analysis qualitatively and quantitatively in the paper. Analytical result showed that the crude oil could be considerably degraded by eating-oil microbes in oily soil and the number of eating-oil microbes increased while the working hours of oil-well risi...

Objective: To analyze the data of pre-hospital emergency treatment in zhengzhou from 2007 to 2016, and evaluate the current situation of pre-hospital trauma emergency treatment, in order to provide a scientific basis for effective use of first aid resources and enhance success rate of trauma emergency treatment. Methods: Retrospective analysis was conducted based on pre-hospital emergency resources of Zhengzhou Emergency Medical Rescue Center from 2007 to 2016. Results: The total number of pre-hospital emergency treatment cases was 9305687 from 2007 to 2016 in Zhengzhou, of which 418882 were trauma cases. The top five causes of injury were traffic accident injury, cutting injury, beating injury, crushing injury and falling injury. The top five emergency treatments used were oxygen, hemostasis, dressing and fixation, fluid supplementation, analgesics and sputum aspiration. According to different directions of diagnosis, the pre-hospital emergency patients were divided into four groups:emergency treatment group, emergency observation group, admission to general ward group and admission to ICU group. There was no statistical difference in the ages among the four groups (P>0.05). There were significantly statistical differences in gender composition among the four groups, with more males than females (P0.05), but the mortality of the trauma, the average arrival time, and the mean treatment time were significantly different (P<0.01). Conclusions: The number of pre-hospital emergency trauma patients increased year by year, but the constituent ratio changed little. CRAMS score is important for the patients triage. Through the training of primary trauma care, the constituent ratio of death was reduced, and the average treatment time was short

Objective： Light quality has effect on the accumulation of gypenosides in the medicinal plant Gynosternma pentaphyllum in the family Cucurbitaceae, while the squalene synthase （SS） and squalene epoxidase （SE） are the key enzymes for gypenoside biosynthesis, The objective of this study was to elucidate the rela- tionship between light quality and biosynthesis key enzyme involving the regulation of gypenoside accu- mulation. Methods： The content of total gypenosides was measured by colorimetric method and the expression of SS and SE gene was determined by quantitative Real-time PCR in the seedlings of G. pentaphyllum which were grown with different light quality. Results： Light quality showed remarkable impacts on the accumulation of total gypenosides. The highest content of total gypenosides in the plant under red light condition was determined, followed by blue light and white light, while the lowest content was recorded under dark condition, qRT-PCR analysis proved that the expression levels of SS and SE genes were also affected by light quality. The high-level gene expressions of SS and SE were found in the plant under red light condition, followed by blue light, with the least content in darkness. The statistical analysis revealed that the total gypenosides were significantly different in different light treatment and the content of total gypenosides was positively related to the expression of SS and SE genes. Conclusions： Light quality regulates gypenoside accumulation via altering the expression of SS and SE in G. pentaphyllum.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.
