This document specifies an architecture and a gateway-to-gateway protocol for the implementation of fibre channel fabric functionality over an IP network. This functionality is provided through TCP protocols for fibre channel frame transport and the distributed fabric services specified by the fibre channel standards. The architecture enables internetworking of fibre channel devices through gat...

Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation i...

Pumped by a narrow band Nd(3+)-doped fibre laser, a grating-free three-wavelength Raman fibre laser has been demonstrated. More than 1.3W output power at the third Stokes line of 1230 nm, a bandwidth of 1.8nm and a slope efficiency of ~28% was measured. A four-wavelength Raman fibre laser was also demonstrated using a different resonator that consisted of a 4% fibre end reflector, a dielectric ...

A theoretical model of a single piezoelectric fibre pull-out is developed to study the interaction between fibre deformation, pull-out stress and corresponding electrical field. Computer simulation of the stress–displacement curve of the fibre pull-out process is presented. Numerical examples show that the piezoelectric fibre pull-out behaviour can be both described and affected by its electric...

Experimental study on the influence of fibre content on crack behaviour and propagation in synthetic-fibre reinforced beams has been reported in this paper. The tensile behaviour of metallic fibre concrete is evaluated in terms of residual flexural tensile strength values determined from the load-crack mouth opening displacement curve or load-deflection curve obtained by applying a centre-point...

From the known statistics of fibre-fibre contacts in random fibre networks, an analytic estimate is obtained for the variance of local porosity in random fibre suspensions and evolving filtrate networks. The variance of local porosity, and hence the distribution of projected areal density, seems to depend on fibre geometry only through the cube of mean diameter. Also, the coefficient of variati...

Definition of dietary jibre Dietary fibre is defined as the remnants of vegetable cell walls which are not hydrolyzed by alimentary enzymes of man (Trowell, 19-72 a,b; Cummings, 1973). Dietary fibre appears to be identical with unavailable carbohydrate (celluloses and hemicelluloses) and lignin (Southgate, 1969). Food tables do not report the constituents of dietary fibre by direct analysis; cr...

High cereal fibre intake is associated with reduced risk for type 2 diabetes, but wheat fibre had little or no effect on glycaemic control or oral glucose tolerance in clinical trials lasting 4-12 weeks. To explain this discrepancy, we hypothesised that colonic adaptation to increased wheat fibre intake takes many months but eventually results in increased SCFA production and glucagon-like pept...

The structural changes of phalloidin-rhodamin labelled F-actin at relaxed and contracted skeletal muscle fibre containing phosphorylated myosin and at contracted state after dephosphorylation were investigated by measuring of polarized fluorescence of the fluorophore. The mechanical properties (isometric tension development) of fibre were studied in parallel. At submaximal concentration of Ca i...

This paper describes an investigation of the influences of chlorine dioxide treatment on fibre surface lignin. The fibre surface characteristics and the interfacial behaviour of the sisal fibre/phenolic resin composites were also studied by SEM, AFM, and XPS. The results show that the surface of the untreated fibre contains a large amount of lignin with granular structure and non-granular struc...
