This paper explores the effects of adding synthetic reinforcing fibres to highstrength reinforced concrete columns and in particular only to the cover of the columns. An experimental program was conducted where seven circular reinforced concrete columns were tested with varying fibre content-one contained no fibres, two contained fibres throughout the cross-section and four contained fibres only in the outer concrete. The other column properties were kept the same for all the seven columns. All seven columns were tested by the application of a concentric, axial compression force. It was found that although only minor improvements were noticeable for a fibre …

Fouling in membrane filtration processes is problematic but inevitable as it occurs with the retention of contaminants that accumulate on the membrane surface. The causes of fouling are often specific, depending upon feed water constituents, the membrane, and the operation regime. Therefore, it is desirable that a thorough investigation is performed on fouled membrane elements of the affected plant. This technique is known as "membrane autopsy", which identities the cause of poor membrane performance, and hence, gives the opportunity to rectify or mitigate the problem and improve future plant design. In this study, the cause of membrane fouling at a …

This paper explores the effects of adding steel fibres to high-strength reinforced concrete columns and in particular only to the cover of the columns. An experimental program was conducted where seven circular reinforced concrete columns were tested with varying fibre content - one contained no fibres, three contained fibres throughout the cross-section and three contained fibres only in the outer concrete. The other column properties were kept the same for all the seven columns. All seven columns were tested by the application of a concentric, axial compression force. It was found that although only minor improvements were noticeable fora fibre …

The development of highly flexible fibre batteries based on conducting polymers is described. The performance of cells with polypyrrole–hexafluorophosphate (PPy/PF6) and polypyrrole–polystyrenesulfonate (PPy/PSS) is evaluated. Based on the results, fibre batteries consisting of a PPy/PF6 cathode and a PPy/PSS anode are fabricated and tested in an electrolyte of 1M LiPF6 in a mixture of ethylene carbonate and dimethyl carbonate. Capacities in the order of 10 mAh g−1 over 30 cycles were observed. © 2005 Elsevier B.V. All rights reserved.
