An optical method of experimentally quantifying the coating progress in a laboratory prismatic spouted bed is presented. Microcrystalline cellulose particles with size dp = 0.57 mm are used as core material. Waterborne coating suspensions with methylene blue as a dye are used and sprayed via a two-fluid nozzle in bottom-spray configuration. A high-speed camera with a color filter is positioned in front of the observation window of the three-dimensional plant and records the flow pattern in the process chamber with a certain frequency. With increasing surface coverage, the particles become bluer and darker. The change in brightness is detected by digital image analysis. In the implemented algorithm, the spherical particles are detected, cut from the background and normalized regarding their lighting and area. The detection of coated pixels on the single particles allows the calculation of the coating fraction and coating uniformity after a Kalman filter has been applied to reduce noise. It is shown that the method can be used to determine the time needed to reach the maximum blue value indicating a complete coating of the particle bed. Besides the minimum coating duration, information on the spraying performance (e.g., the time point of a possibly occurring blockage of the nozzle) can be obtained from the data. Two exemplary experiments are presented, showing a connection of the slope of the coating fraction and the uniformity of the coating of the particles in the apparatus that results in the recommendation of a slow liquid injection for obtaining consistent coating layers as desired in many applications.

作者： j. jager T. Keil Electrical Power System Friedrich-A lexander- University Erlangen-Nuremberg Erlangen 91058 Germany

A deregulated power market is making short-circuit currents likely to exceed the thermal or mechanical permissible limits of switchgear. Consequently fault current limiters （FCL） become more necessary in power systems. The use of FCLs has an impact on the protection schemes and functions in power systems. Thus, before FCLs can be applied in the network, the impacts on existing protection system must be understood. Depending on the current limiting technique used, today＇s protection concepts may have to be adapted or revised to ensure proper network protection selectivity. A relationship between fault current limiters and protection schemes should be established by taking into account both protection and network specific issues, such as the impact of different FCL technologies, existing and new protection concepts, selectivity and innovative network. This paper is presenting a frame work for accomplishing this task.

关键词： Fault current limiter first cycle behavior follow current protection system pick-up processing selectivity coordination.

许多眼科疾病在中老年人群中的患病率高于其他年龄组，随着全球老龄化社会的到来，眼科医师面临着年龄相关性眼病疾病谱迅速扩大的挑战，加强年龄相关性眼病的预防对于中老年人的健康有着重要意义。因此，了解年龄相关性黄斑变性（AMD）、青光眼和葡萄膜黑色素瘤易在老年人中发病的原因至关重要。我们先前的动物实验研究表明，正常的老化过程伴随着炎症反应，这种反应增加了眼部疾病发病的风险，而加重炎症反应的环境因素是吸烟。目前已发现炎症参与AMD的发病和进展，并且可能在青光眼、葡萄膜黑色素瘤的病理过程中发挥作用，巨噬细胞和淋巴细胞增加了肿瘤转移的风险。一些实验研究也表明，巨噬细胞在脉络膜／视网膜炎症、眼内肿瘤等疾病中发挥关键作用。巨噬细胞分为M1型和M2型，前者刺激特异性免疫反应，后者可刺激血管的生成。在机体老化过程中，M1型的功能可以向M2型转化，从而可能促进AMD和肿瘤的进展。深入研究巨噬细胞的特性有助于老化过程的干预和年龄相关性眼病的预防。
