电针应力点加夹脊穴治疗下腰伤病46例

分析脊柱生理弯曲解剖结构,结合下腰伤痛多发生在腰骶部的临床表现,提出主穴应力点位于腰骸部劳损组织。作者认为,引起下腰伤痛的病变组织,正好位于应力点。针刺夹脊穴腰段疼痛区,兴奋脊神经后支,血行痛止,以治其标。电针应力点,以针代刀,松解劳损组织,松则不痛,以治其本。介绍电针应力点加夹脊穴治疗下腰伤痛46例,有效率为89％。

我国公共图书馆治理模式研究——比较视角下的政策观念诠释

国家新出台的一系列政策就公共图书馆体制机制重大问题提供了一个全新的治理模式。通过宏观和微观两种视角,对我国图书馆领域新旧政策、观念的比较可见,传统公共图书馆体制机制的障碍主要有行政权力垄断、资源配置方式单一、城乡发展失衡、公共服务目标不明确、责任关系不清、法人治理结构不完善等。在系统解读和诠释新政策内涵的基础上,可以得出我国公共图书馆治理模式应为“党委领导、政府负责、社会协同、公众参与”的公共治理模式。

“长吉诗派”论

李贺的诗在中唐诗坛独树一帜,被人称之为“长吉体”。对其发展轮廓和轨迹作一勾勒,探讨其形成缘由。它的发展,首先是由李贺诗之特质所决定,而这一特质成为一种具有典型意义的抒情范式。从这个意义上审视,“长吉诗派”在后世之发展与延续,是李贺人生悲剧在后世重演的结果。     

Design and fabrication of an surface acoustic wave resonator based on AlN/4H-SiC material for harsh environments

Surface acoustic wave (SAW) sensors and micro-electromechanical system (MEMS) technology provide a promising solution for measurement in harsh environments such as gas turbines. In this paper, a SAW resonator (size: 1107 μm× 721 μm) based on the AlN/4H-SiC multilayer structure is designed and simulated. A MEMS-compatible fabrication process is employed to fabricate the resonator. The results show that highly c-axis-oriented AlN thin films deposited on the 4H-SiC substrate are obtained, with that the diffraction peak of AlN is 36.10° and the lowest full width at half maximum (FWHM) value is only 1.19°. The test results of the network analyzer are consistent with the simulation curve, which is very encouraging and indicates that our work is a significant attempt to solve the measurement problems mainly including high temperature stability of sensitive structures and the heat transmission of leads in harsh environments. It is essential to get the best performance of SAW resonator, optimize and characterize the behaviors in high temperatures in future research.     

Simulation study on fluctuant flow stress scale effect

INTRODUCTION With the continuous development of science and technology, especially the rapid progress of electronic industry and micromachine, microparts are needed more and more, and their technical requirements are higher and higher (Geiger et al., 1994; 1996; Geiger and Engel, 2002). However, traditional processing technologies, like cutting, etc., do not meet these requirements. Traditional plastic forming technology has merits like high production rate, excellent me-chanical proper…     

Enhanced production of elastase by Bacillus licheniformis ZJUEL31410： optimization of cultivation conditions using response surface methodology

Sequential methodology based on the application of three types of experimental designs was used to optimize the fermentation conditions for elastase production from mutant strain ZJUEL31410 of Bacillus licheniformis in shaking flask cul- tures. The optimal cultivation conditions stimulating the maximal elastase production consist of 220 r/min shaking speed, 25 h fermentation time, 5% (v/v) inoculums volume, 25 ml medium volume in 250 ml Erlenmeyer flask and 18 h seed age. Under the optimized conditions, the predicted maximal elastase activity was 495 U/ml. The application of response surface methodology resulted in a significant enhancement in elastase production. The effects of other factors such as elastin and the growth factor (corn steep flour) on elastase production and cell growth were also investigated in the current study. The elastin had no significant effect on enzyme-improved production. It is still not clear whether the elastin plays a role as a nitrogen source or not. Corn steep flour was verified to be the best and required factor for elastase production and cell growth by Bacillus licheniformis ZJUEL31410.
