Jan 01, · On the basis of differences in the signal intensity, SIM allows one to discriminate the dynamics of very proximal or bundled microtubules even if these cannot be resolved optically (Komis et al., ). Although not as effective as STED (see below) or PALM/STORM in superresolving intracellular structures, linear SIM offers several advantages Cited by: Analysis of woven fabric strengths eventually to the fabric. Each level has its own geometrical and mechanical variables which control or influence to varying degrees the fabric behavior. It will be a formidable or even impossible task to include all these variables into a fabric model without simplifica-. Apr 14, · 5 The OSI Reference Model Reasons for Standardization The Open System Interconnection (OSI) Reference Model was specified by ITU, in cooperation with ISO and IEC, and is documented in Recommen- dation X Although the OSI model is applicable in many areas, it is used mostly in the area of communication between computers. KSB is one of the world's leading manufacturers of pumps and valves and also offers a comprehensive range of service activities. The company's products and services are used in process engineering and building services, water and waste water management, and in the energy and mining sectors.
