The cell line, RCS-LTC (derived from the Swarm rat chondrosarcoma), deposits a copious extracellular matrix in which the collagen component is primarily a polymer of partially processed type II N-procollagen molecules. Transmission electron microscopy of the matrix shows no obvious fibrils, only a mass of thin unbanded filaments. We have used this cell system to show that the type II N-pro-collagen polymer nevertheless is stabilized by pyridinoline cross-links at molecular sites (mediated by N- and C-telo-peptide domains) found in collagen II fibrils processed nor-mally....

Introduction to Signal Transmission and the Basic Line Circuit To make it suitable for carriage over most telecommunications networks, information must first be encoded in an electrical manner, as anelectrical signal. Only such signalscan be conveyed over the wires and exchanges that comprise ‘transport the mechanism’ of telecommunications networks.Overtheyears,avarietyofdifferentmethodshave been developed forencoding different types of information.

To move signals of that frequency around efficiently within my transmitting station needed what can only be described as plumbing transmission lines made out of thin copper pipes and ceramic insulators—the alternative being expensive, specially constructed, but very high loss, coaxial cable. Yet here we are twenty years later happily shoving similar frequencies down twisted pairs without really thinking about the physics involved! Three factors about radio frequency signals are very important in understanding our problem:...

Dưới sự biến thiên rất nhanh của dòng điện sét, thành phần điện cảm có ảnh hưởng rất lớn đến sự phân bố điện áp trên hệ thống nối đất, hơn nữa có thể xảy ra hiện tượng phóng điện trong đất và ảnh hưởng tương hỗ giữa các thanh dẫn làm cho quá trình tính toán và mô phỏng hệ thống đất gặp nhiều khó khăn. Transmission Line Modeling (TLM) là một phương pháp có thể mô phỏng được quá trình quá độ và các hiện tượng xảy ra trong hệ thống nối đất phức tạp của trạm biến áp (nối đất dạng lưới)....
