Recently, in polymer technology, there has been an evident change in the production of flexible functional film materials and devices on flexible polymer substrates. The aforementioned products are used in power engineering (light-emitting materials, solar cells), medicine (materials with incorporated drugs and other special ingredients, functionalized membranes, medical transdermal films), electronics (chips, materials for matrix radiation receivers), analytical equipment (active elements of devices for monitoring of optical, electrical, and mechanical characteristics; chemical sensors), consumer products (chips for everyday electronic devices, materials for intelligent packaging,"labels" for information coding, etc.).

北京孔庙和国子监博物馆现存明代进士题名碑77通,其中20通石碑的碑阴处刻有"试官题名",记载着殿试考官的信息。进士题名碑上的试官题名源自宋代,传承于元,结束于明中期,现存可见者均为明代碑刻。题名碑上的试官题名虽已有风化现象,但大多数考官信息仍可辨识,是非常珍贵的科举原始资料,将其与《登科录》比对,可填补永乐朝殿试考官信息。同时,两种材料亦可互相订正,纠正讹误,为研究明代考官制度提供更加准确的资料。 相似文献

This study of National Public Radio's "letters from listeners" segments applies two theoretical frameworks–imagined community and news work–to suggest that the practice of "imagining community" is a distinct practice of journalism. The findings suggest that NPR producers use letters segments to encourage listeners to feel as if they are part of a community. In selecting and packaging those comments, producers construct an imagined community that reflects the producers' own journalistic values, such as balance, accountability, and accuracy. The conclusion suggests that community-imagining might be especially difficult and abstract for large news media organizations serving massive and dispersed audiences. 相似文献

我们应该怎样进行学术研究--关于图书馆学研究的几个问题(三) 总被引：1，自引：0，他引：1
“写什么”与“怎样写”是学术研究的基本问题。要善于在工作中培养“问题意识”,这是学术研究的前提。学术研究首先要详细地占有材料,其次要用“思想”的线把材料串起来,做有“思想”的学术。多读、博学是学术研究的底蕴。 相似文献

社交媒体虚假健康信息特征识别 总被引：3，自引：2，他引：1
[目的/意义] 识别社交媒体虚假健康信息特征,构建社交媒体虚假健康信息特征清单,以期为社交媒体虚假健康信息特征的测度提供一定理论支撑,也为用户和社交媒体平台判别虚假健康信息提供有益参考。[方法/过程] 采集1 004条社交媒体健康数据,利用程序化编码抽取社交媒体虚假健康信息的关键特征,运用卡方检验和方差分析揭示社交媒体虚假健康信息的显著特征,并构建社交媒体虚假健康信息特征清单。[结果/结论] 研究结果表明,社交媒体虚假健康信息特征具有表面特征、语义特征和来源特征3个维度、11个主要特征以及29个子特征。其中,社交媒体上食品安全主题的虚假健康信息在"术语包装"特征上表现得更为显著;"夸大事实"为社交媒体上常见疾病主题虚假健康信息的显著特征;社交媒体上养生保健主题的虚假健康信息具有"元数据缺失"和"假借权威"显著特征。 相似文献

Using a 10 percent random sample of all requests submitted to the Midwest Regional Medical Library during 1968-1969, this study has revealed that physicians constitute the user group making the most requests, that physicians request periodical materials most, that 86.6 percent of materials requested were for periodicals, and that over one-third of materials requested was more than ten years old. It was found that 66.3 percent of requests were filled, that "Pathology, Diseases, and Treatment" was the subject category with the highest percentage of requests, and that this category and Materia Medica were the subjects accounting for over 50 percent of the requests from all users. The subject categories most frequently requested by physicians were found to be the same (Pathology, Diseases, and Treatment and Materia Medica) as for educators and researchers. The most requests from students were in the Materia Medica and "other" subject categories. These findings are significant for drawing up acquisition policy for both the John Crerar Library, which supplies the physical facilities for the MRML, and the borrowing library which submits the requests for users. 相似文献

清代"伊犁九城"主要包括惠远老城(后废弃,迁新址,名惠远新城)、惠宁城、塔勒奇城、绥定城、广仁城、瞻德城、拱宸城、宁远城、熙春城等城址。本文通过区域性的系统调查和考古勘探,结合CORONA卫星影像,基本复原了伊犁九城的建制,补充文献所述及前人研究之不足。伊犁九城总体保存情况较差,但部分遗迹尚存,其中北墙保存情况相对较好。伊犁九城具有较为鲜明的统一性、层级性、联合性等特点。统一性主要体现在方形形制以及城内十字干道的结构布局,还体现在其军事驻防属性上;层级性是在城址规模、建筑上呈现出来;联合性表现为九城之间有隶属关系,在战略上互为掎角之势,形成防御体系。伊犁九城防御体系形成了"双核"的布局模式。 相似文献

C. Trenton Boyd 《Journal of the Medical Library Association》2011,99(1):8-14
Objective:
The objective of this study was to survey holdings of ephemeral veterinary literature.Methods:
WorldCat OCLC catalog, the Library of Congress online catalog, the US National Agricultural Library online catalog, and the Dictionary Catalog of the National Agricultural Library, 1862–1965, were used to determine current library holdings of materials published by veterinary schools that are no longer in existence and veterinary associations that are defunct, veterinary supply catalogs, veterinary house organs, patent medicine publications, and veterinary advertisements. Individual library catalogs were also consulted. In addition, the practice of removing advertisements from bound volumes was examined.Results:
There are many gaps in the cataloged library holdings of primary source materials relating to the history of the education of veterinarians in the United States.Conclusions:
A proactive action plan needs to be designed and activated to locate, catalog, and preserve this primary source material of veterinary medicine for posterity.Highlights
- Veterinary libraries have failed to catalog or retain important primary veterinary source materials.
- Several types of veterinary gray literature, with individual pieces scattered across multiple kinds of libraries, are at high risk for loss from the historical record.
Implications
- Academic, veterinary, medical, and special librarians should be involved in efforts to preserve their institutional, local, and state materials; to identify and locate hidden collections of materials, both in uncataloged collections and in the hands of private collectors; and to mentor new librarians about their role in preserving the history of medicine.
- The results of this survey of primary source materials documenting US veterinary medical education suggest the need for a parallel study of medical education and other health professions education.
- The time is now, not only to digitize important scarce veterinary materials for both preservation and improved access, but also to archive present day institutional output (paper and electronic).
