Decoration of disclinations by solidification-induced band texture and focal-conic texture for a low-molar-mass liquid crystal

Two decoration techniques, solidification-induced band texture decora tion and focal-conictexture decoration, have been established to exhibit the director field of disclinations in a low-molar-mass methacrylate liquid crystal. The disclinations with strength s = 1/2 and s = ±1 are observed by the two decor ation methods. For the solidification-induced band texture decoration, the molecular orientation is perpendicular to the direction of the band. While for focal- conictexture decoration, it has been proved by the results of IR dichroism that the direction of the director is parallel to the direction of the focal-conic. Therefore, the sketch map of the molecular director filed can be mapped according to the morphological pattern of the solidification-induced band textureor focal-conic texture.

蝗虫体内无机物的百分含量

动物体的鲜重(FM)、干重(DM)、灰分重(AM)及其比值在不同分类群和不同生态型的动物类群中变化很大,其中 DM/FM 和 AM/DM 比值反映了动物体水、无机矿物质和有机物三者之间的比例,是了解动物体化学组成的两个重要参数.我们在进行直翅目蝗总科昆虫整体痕量元素含量分析的同时,测定和计算了35种蝗总科昆虫的AM/DM 比值,现将结果以及其它主要动植物类群的有关资料一并介绍如下.     

用于CIMSERC网络性能评价的NPES设计与实现

分析建模的方法用于CIMS网络性能评价是有其局限性的。本文介绍的是一个基于仿真方法的CIMSERC网络性能评估模拟器——NPES的设计与实现。该NPES可作为进行CIMSERC网络性能评价的“实验床”和评估工具.CIMSERC网络的基本结构是二个互连的基于Ethernet的TCP/IP网,设计中用于观测和评价的性能指标包括:网络系统的吞吐量、利用率、以及信息包传输延迟等。CIMSERC的NPES用SIMAN和FORTRAN语言混合实现。     

Photon emission of phagocytes in relation to stress and disease.

Phagocytes, the first-line cells of the body's defence mechanisms against invading pathogens, kill microorganisms by means of lysosomal degradative enzymes and highly toxic reactive oxygen intermediates. The reactive oxygen compounds are produced, in a process called the 'respiratory burst', by the NADPH oxidase complex in plasma membranes, and by myeloperoxidase in phagolysosomes after degranulation. These processes generate electronically excited states which, on relaxation, emit photons, giving rise to phagocyte chemiluminescence (CL). This paper describes the conditions for the measurement of CL, and reviews the activity of phagocytes from individuals undergoing stress or disease. The capability of phagocytes to emit photons reflects remarkably well the pathophysiological state of the host. In many cases even the magnitude of the stress, the presence of a pathogen in the body, or the activity of the disease can be estimated. Physiological changes, e.g. in the reproductive cycle, can also be predicted.
