Mineral carbonation, which precipitates dissolved carbon dioxide(CO_(2)) as carbonate minerals in basaltic groundwater environments, is a potential technique for negative emissions. The Leizhou Peninsula in southwest Guangdong province has extensive basalt, indicating a promising potential for CO_(2) storage through rapid mineralization. However, understanding of the basic geological setting, potential, and mechanisms of CO_(2) mineralization in the basalts of the Leizhou Peninsula is still limited. The mineralization processes associated with CO_(2)storage at two candidate sites in the area are investigated in this paper: Yongshi Farm and Tianyang Basin(of the dried maar lake). Petrography,rock geochemistry, basalt petrophysical properties, and groundwater hydrochemistry analyses are included in the study. Numerical simulation is used to examine the reaction process and its effects. The results show that basalts in the study areas mainly comprise plagioclase, pyroxene, and Fe–Ti oxides, revealing a total volume fraction exceeding 85%. Additionally, small amounts of quartz and fayalite are available, with volume fractions of 5.1% and 1.0%, respectively. The basalts are rich in divalent metal cations, which can form carbonate minerals, with an average of approximately 6.2 moles of metal cations per 1 kg of rock. The groundwater samples have a pH of 7.5–8.2 and are dominated by the Mg–Ca–HCO3 type. The basalts demonstrate a porosity range of 10.9% to 28.8%, with over 70% of interconnected pores. A 20-year geochemical simulation revealed that CO_(2) injection dissolves primary minerals, including anorthite, albite, and diopside, while CO_(2)mineralization dissolves precipitation secondary minerals, such as calcite, siderite, and dolomite. Furthermore, a substantial rise in pH from 7.6to 10.6 is observed in the vicinity of the injected well, accompanied by a slight reduction in porosity from 20% to 19.8%. Additionally, 36.8% of the injected CO_(2) underwent complete min

World Journal of Gastroenterology 1999年第5期5卷 435-439页

INTRODUCTIONPromoting hepatocyte growth factor (pHGF) extracted from the sucking pig liver is a series of polypeptides with molecular weight less than Mr 10000 and has specific biological activities to stimulate the rat hepatocyte DNA synthesis after 1/3 partial hepatectomy and promote recovery of rat hepatic injuries induced by endotoxin and D-aminogalatose. These properties are similar to the results reported by Labrecque[1]. pHGF can effectively cure clinical acute fulminant hepatitis, chronic hepatitis and other hepatic injuries by significantly reducing serum alanine aminotransferase (sALT), eliminating jaundice and increasing the survival rate of fulminant hepatitis[2,3].

A Time Domain Computation Method for Dynamic Behavior of Mooring System

A quasi-steady time domain method is developed for the prediction of dynamic behavior of a mooring system under the environmental disturbances, such as regular or irregular waves, winds and currents. The mooring forces are obtained in a static sense at each instant. The dynamic feature of the mooring cables can be obtained by incorporating the extended 3-D lumped-mass method with the known ship motion history. Some nonlinear effects, such as the influence of the instantaneous change of the wetted hull surface on the hydrostatic restoring forces and Froude-Krylov forces, are included. The computational results show a satisfactory agreement with the experimental ones.

IT is well known that oocytes, in general condition, can be penetrated by sperm rather thanround spermatids. In 1993, Ogura injected round spermatid nuclei into hamster oocytes anddemonstrated that the spermatid nuclei could transform into pronuclei with DNA synthesis andthat their chromosomes mingled with oocyte chromosomes immediately. In order to avoid themechanical damage to the oocytes, an alternative method, cell-to-cell fusion, was used. Ap-proximately 20%—40% and 30% of round spermatids could be fused with oocytes by

事件抽取是一项重要的信息抽取任务,现有的事件抽取方法大多假设一个句子中仅出现一个事件,然而,在真实的场景下,重叠事件是难以避免的。文中提出了一种基于联合学习的语言粒度融合的重叠事件抽取方法。该方法设计了基于token数目逐层递增和逐层递减的策略,对不同语言粒度的片段进行表示,在此基础上,构建了渐进式语言粒度融合的句子表示。通过引入事件信息感知,建立了基于门控机制的语言粒度和事件信息融合的句子表示。最后,通过联合学习词间的片段关系和角色关系,实现对事件触发词、论元、事件类型和论元角色的判别。在FewFC和DuEE1.0-1数据集上进行了实验,所提LGFEE模型在事件类型判别任务上的F1值分别提高了0.8%和0.6%,在触发词识别、论元识别、论元角色分类任务上也获得了较高的召回率和F1值,验证了其有效性。
