ABSTRACTGlocalization describes the adaptation of international products around the particularities of a local culture, and extends to areas beyond political campaigns and cultural communication. Chinese continuing resources are effectively influenced by glocalization, which reflects the changing society in China and Chinese overseas communities, as well as the changing practice in Chinese studies all over the world. Glocalization brings unexpected challenges to a library's cataloging service, and a number of issues need to reach our awareness and be solved. We have to face squarely its influence, and look for an appropriate solution in handling Chinese continuing resources under glocalization. 相似文献

地下水控制是大型深基坑工程中的关键技术。结合某周边不规则的深基坑工程,从基坑周边既有工程环境、施工场地条件、基坑地质和含水层特征等多方面综合考虑,对基坑场地内上层滞水和孔隙承压水分别提出控制设计思路,给出排水管路、深井降水网布置设计方法,以及降水井结构设计图,最后评价地下水控制对深基坑周围环境的影响。对于类似建筑,具有一定的参考价值。 相似文献

与科学世界图景中的水概念不同,语言世界图景中水的概念化呈现出自己的特点。通过对以水为关键词的搭配为语料对水进行的概念分析发现,英语中将水概念化为动物、人、有固定外形的物体和无固定外形的物体。尽管其概念化呈现出无序性和非逻辑性,但反映出在英伦民族意识中对水这一概念的初始认识。 相似文献

Mutations and transient conformational movements of the receptor binding domain (RBD) that make neutralizing epitopes momentarily unavailable present immune escape routes for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To mitigate viral escape, we developed a cocktail of neutralizing antibodies (NAbs) targeting epitopes located on different domains of spike (S) protein. Screening of a library of monoclonal antibodies generated from peripheral blood mononuclear cells of COVID-19 convalescent patients yielded potent NAbs, targeting the N-terminal domain (NTD) and RBD domain of S, effective at nM concentrations. Remarkably, a combination of RBD-targeting NAbs and NTD-binding NAbs, FC05, enhanced the neutralization potency in cell-based assays and an animal model. Results of competitive surface plasmon resonance assays and cryo-electron microscopy (cryo-EM) structures of antigen-binding fragments bound to S unveil determinants of immunogenicity. Combinations of immunogens, identified in the NTD and RBD of S, when immunized in rabbits and macaques, elicited potent protective immune responses against SARS-CoV-2. More importantly, two immunizations of this combination of NTD and RBD immunogens provided complete protection in macaques against a SARS-CoV-2 challenge, without observable antibody-dependent enhancement of infection. These results provide a proof of concept for neutralization-based immunogen design targeting SARS-CoV-2 NTD and RBD. 相似文献

Introduction:
Two Italian adults arrived at the Emergency Department referring diarrhea, nausea and vomiting for 4 days; weakness, fatigue and visual hallucinations were also complained of. Patients reported the ingestion of some leaves of a plant, which they supposed to be “donkey ears”, a week before. Physical examination showed hypotension and bradycardia and ECG examination disclosed sinus rhythm and repolarization abnormalities (scooping of the ST-T complex) in both patients and a 2:1 AV block in the man.Materials and methods:
Digoxin concentration was evaluated twice for each patient (at the admission and after 4 hours) by the automated immunoassay system ADVIA Centaur®. Digitoxin concentration was evaluated by liquid chromatography-mass spectrometry (LC-MS/MS).Results:
Despite clinical picture was suggestive of digitalis intoxication, digoxin levels were undetectable. Due to the more severe clinical picture, the male patient was treated with anti-digoxin antibodies (Digifab®) achieving a good clinical improvement and remission of the AV block within two hours. Initial diagnosis was confirmed by LC-MS/MS showing high digitoxin concentrations, but digoxin was undetectable. Patients remained stable and 48 hours later were discharged from the hospital.Conclusion:
Whereas digoxin determination frequently relies on monoclonal antibodies which do not cross-react to digitoxin, polyclonal antibodies constituting Digifab® recognize a large spectrum of cardiac glycosides, including digitoxin. This report emphasizes the primary role of the clinical approach to patients in the emergency setting and how an active communication and a continuous sharing of professional experiences between Laboratory and Clinicians ensure an early and correct diagnosis. 相似文献7.
Using normal adult readers, this study examined the relative involvement of magnocellular and parvocellular processes in reading
English phonologically regular pseudowords and irregular words presented in isolation and in contiguity from left to right.
The data showed that a low temporal frequency visual measure that implied more parvocellular involvement was active in processing
irregular words presented singly and pseudowords presented in contiguity. However, the results failed to show the involvement
of the magnocellular pathway (as implicated by low spatial and/or high temporal frequency visual measures) in reading words
presented in contiguity from left to right. The discrepancy was discussed in terms of the sensitivity of the tasks used in
testing the two pathways. 相似文献

空间隐喻属于概念隐喻的三种分类之一,是认知的基础。时间概念是抽象的,具体的空间方位词可用来描述和衡量时间的变化。文章基于时间的空间隐喻系统,观察大量不规则动词过去式双元音发音位置的变化,分析对比得出:时间的空间隐喻系统在语音方面也有所呈现。这印证了隐喻是一种认知方式并普遍存在于人类的思维中这一观点。 相似文献
