The fibers used in concrete are mainly materials that require additional production, which negatively affects their cost and environmental friendliness. Therefore, the issue of effectiveness use natural fibers, extraction does not mechanized becomes relevant. One these is sisal fiber. main purpose this work was to study effect adding on structure properties environmentally friendly concretes wi...

The ability to accurately identify fibres is of importance to conservators, allowing the most appropriate methods of treatment to be employed. Our research has concentrated on the development of an ATR FT-IR spectroscopic technique for the characterisation of cellulosic (plant) fibres. Six species of fibre were examined, taken largely from the bast group (flax, hemp, jute and ramie), along with...

The issue of scalability is key to the success of massively parallel processing. Due to their distributed nature, message-passing multicomputers are appropriate for achieving scalar performance. However, the nzessagepassing programming model lacks programmability due to difficulties encountered by the programmers to partition and schedule the computation over the processors and to establish eff...
