Prevotella bivia is associated with pelvic inflammatory disease. A 77-year-old man developed a rapidly growing chest wall abscess due to P. Bivia within days. He underwent surgical resection of the infected area; his postoperative course was un-eventful. This is the first case of chest wall abscess due to P. Bivia infection. Its correct diagnosis cannot be underestimated be-cause fulminam infections can occur in aged or immunocompromised patients if treated incorrectly. Prompt, appropriate surgical management, and antibiotic therapy affect treatment outcome. 相似文献

谈谈"一流博士从何而来"的问题 总被引:4,自引:4,他引:4
博士生培养问题是教育中的大问题,为培养出一流博士,应注意:(1)“一流的学生、三流的老师”现象说明了某些“博导”们的学识与功力面临着急需充实和提高的任务,尤其是科学史与方法论修养更为重要;(2)充分珍重和爱护博士生的“自我发现”至关重要;(3)对论文作品,与其计较其是否进入SCI,不如多加考虑那些认真负责刊物的审稿意见,如能收集到滞后反映则更好;(4)要鼓励博士生养成爱读科学史与科学名人传以及钻研名家原创性著作的兴趣及习惯. 相似文献

高山峡谷与丰富的生态环境特色是太鲁阁国家公园重要的自然资产,是以常为国人进行自然探知、环境教育与游憩休闲的场域。然而藉由人类的系列活动,包括道路的开辟、高冷蔬果的种植以及人造结构物的兴建等,大大的改变了高山地区的生态环境。本研究调查太鲁阁国家公园园区海拔1200m以上高山地区土地资源利用情形,针对已被利用的高山环境以不同时期的遥测影像分析,以了解其变化情况。研究显示土地资源的利用是与地貌条件及交通易达性有密切相关;开发区概以公路两侧,并以西段通往梨山、雾社之大禹岭为最。国家公园成立后的开发受到限制是以变异性不大,未来国家公园对园区内自然保育与生态环境维护仍应持续以积极的态度面对,并建构长期监测机制及技术,以做为未来对已开发区之土地经营管理之参考。 相似文献

China is a nation with many different nationalities. Each has its own history, language and tradition, and maintains its own distinct customs and style of dress. In China, as in other countries, there is evidence that some kind of dramatic art existed during the earliest periods. Chinese dance dates back to nearly 5,000 years. In order to understand Chinese drama, we must first try to find out what their dramatists are trying to do and inquiry into the early origin of drama in China. This paper will introduce three area of discussion that involves drama and dance. They are (1) the historical tale where mythological stories are portrayed in dances, (2) the traditional dances, and (3) a specific development of drama and dance called Peking opera. 相似文献

采用长周期、高Q值的扭秤,并选择恒温、隔振、电磁屏蔽以及外界引力干扰小的实验环境,从而有效克服传统扭秤实验中扭丝的滞弹性和热弹性等影响,采用扭秤周期法在 105×10-6相对精度上测量万有引力常数G。为了进一步提高G的测量精度,还系统研究了精密扭秤实验的各种系统误差及其对G的影响 相似文献
