系部如何做好教材接收与发放工作的探析

结合我院系部发放教材的有益尝试,阐述了系部如何做好教材接收与发放工作,首先,做好发书前的准备工作、安排专人负责,认真核实所到教材品种及数量;其次,安排好学生以专业为单位领取教材次序,发放教材责任落实到人,做到准确有序地发放教材。系部应将教材接收与发放工作纳入科学化、系统化、规范化的轨道,以适应教育教学改革日益发展的需要,为教学提供更好的服务。     

略论“五行”学说的基本内容

"五行"学说在中国哲学史上具有相当重要的地位,但长期以来为人们所忽视,实为一大罕事。从自然界到社会政治、伦理活动,从人体结构到宗教祭祀活动,"五行"学说都无所不及,可见其范围之广,堪称中国古代一个庞大的哲学思潮。这一思潮产生很早,从春秋战国到秦汉,它已成为一种世界观的理论体系,为人们普遍运用,一切事物及其运动变化都以"五行"的作用和属性的相生相胜为基础。因此,探讨"五行"学说的基本内容,具有重要的意义。     

Single cells for forensic DNA analysis--from evidence material to test tube

Abstract: The purpose of this project was to develop a method that, while providing morphological quality control, allows single cells to be obtained from the surfaces of various evidence materials and be made available for DNA analysis in cases where only small amounts of cell material are present or where only mixed traces are found. With the SteREO Lumar.V12 stereomicroscope and UV unit from Zeiss, it was possible to detect and assess single epithelial cells on the surfaces of various objects (e.g., glass, plastic, metal). A digitally operated micromanipulator developed by aura optik was used to lift a single cell from the surface of evidence material and to transfer it to a conventional PCR tube or to an AmpliGrid^® from Advalytix. The actual lifting of the cells was performed with microglobes that acted as carriers. The microglobes were held with microtweezers and were transferred to the DNA analysis receptacles along with the adhering cells. In a next step, the PCR can be carried out in this receptacle without removing the microglobe. Our method allows a single cell to be isolated directly from evidence material and be made available for forensic DNA analysis.     

中药微性状鉴定法

中药微性状鉴定法是近年新提出的一种中药材鉴定方法,通过体视显微镜、生物显微镜和袖珍显微镜等结合适合的电脑软件,观察、拍摄药材表面的细微特征信息,根据药材表面反映出的不同信息特征达到鉴别中药材的目的.该方法不同于显微鉴定法,是性状鉴定法向着微观领域的延伸.
