The cost effective replacement of halogenated materials for the wiring of buildings
نویسنده
چکیده
The wiring of buildings is an emotive subject. Hitherto the unchallenge domain of PVC, the status quo is under threat from many directions. Change is in the air and from all points of view the questions are daunting. PVC is by far the largest wire and cable segment (in Europe 700 kta of compound) and building wire is approximately 50% of this volume. Industrial power cables (e.g. 1 kv) is the second largest category. Low smoke zero halogen materials, which in Europe are the only commercial alternative to PVC, have made significant inroads into the power cable market but with exceptions rather more limited progress in building wire applications. Building wires fall into three categories:

Modified Tension Band Wiring in Adult Distal Humeral Fracture Types A2 and C1
Background: Distal humeral fractures accounts for approximately 2% of all fractures and nearly one-third of humeralfractures in adults. In this regard, Modified Tension Bind Wiring (MTBW) technique was used for the fixation of the distalhumeral fractures type A2 and C1 (AO) to evaluate the early movement and complications of the patients.Methods: This study was conducted on 25...

In the combination of 5-fluorophenyl-1, 3, 7, 9-tetra methylpyrido [2, 3, d, d, 5, 6 dipyrimidine -2, 4, 6, and 8 tetron, there are 4 rings, respectively, ring that is attached to the halogen ring A and, respectively, a ring The lower and the right to the left of the ring A are called C, B, and D. Calculations and studies show that the amount of aromatics in halogen-ring A in all cases has the ...
متن کاملDetermination of Optimum Insulation Thickness for Building Walls in Iran Using Life Cycle Cost Analysis
Air-Conditioning (AC) systems are responsible for a considerable portion of the energy consumption in buildings located in high cooling load requiring regions of Iran. In addition, the heat flow through the buildingschr('39') external walls plays a major role in cooling load estimations for the countrychr('39')s hot regions. Therefore, application of insulation materials in external walls has g...
