Cotton fibres were subjected to cleaning process and then characterized for maturity. Decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and Trichloroethene on the native fibres were carried out. The effects of these on the strength and moisture regain were investigated. The activation energies of the dyeings were also analysed with Durazol Scarlet Red 4 BAS. The r...

The association of cytochrome c oxidase negative fibres (COX-negative) and ragged-red fibres (RR-fibres) with work related trapezius myalgia has been proposed. Hitherto studies have been small or without control groups. The aim of the present study was to investigate the prevalences of RR-fibres and COX-negative fibres in female cleaners with (n=25) and without (n=23) trapezius myalgia and in c...

The number of guided modes in optical fibres is an important aspect of their design and characterisation. Some optical fibres, such as microstructured fibres and Bragg fibres, have no strictly bound modes in the same sense as in conventional step and graded index fibres. All modes in these fibres are leaky so what exactly becomes regarded as a mode becomes important.. We propose a method for co...

BACKGROUND In dystrophic mdx skeletal muscle, aberrant Ca2+ homeostasis and fibre degeneration are found. The absence of dystrophin in models of Duchenne muscular dystrophy (DMD) has been connected to altered ion channel properties e.g. impaired L-type Ca2+ currents. In regenerating mdx muscle, 'revertant' fibres restore dystrophin expression. Their functionality involving DHPR-Ca2+-channels is...

In this research, several series of triarylmethane dyes containing one or more terminal methoxy substituents with a variable tertiary amino groups have been used. These dyes have been applied to different substrates by using various methods including transfer printing and then their fastness properties were measured. These dyes shows exceptionally high light fastness (6-7) on acid modified poly...

1. The ionic dependence of action potentials evoked in giant smooth muscle fibres isolated by enzymatic digestion from the body wall of the marine invertebrate Beroe ovata (Ctenophora) has been investigated using conventional electrophysiological techniques. 2. Differences were observed in the two fibre types studied. The resting membrane potential was —60 ± 135 mV (JV = 25) in longitudinal mus...

white, red and superficial. In common with teleost fish, the different types are well segregated in the body. The white fibres make up the bulk of the body, the red fibres form a band along the lateral edge of the body and the single layer of superficial fibres is confined to a narrow band between the skin and the red fibres. Each fibre type has a distinct histological and biochemical profile w...

An efficient technology for preparing lotus fibres under microwave irradiation was developed. The lotus fibres were characterized by scanning electron microscopy, Fourier transform infrared spectrometry, X-ray diffraction and thermogravimetry. Lotus fibres prepared are a kind of hollow fibres which are composed of a superfine fibre and an external shell. The effect of the treatment time with hy...

The occurrence and distribution of neuropeptide-containing nerve fibres in the human circumvallate papillae were examined by the peroxidase-antiperoxidase immunolocalisation method using surgical specimens that had not been subjected to radiotherapy, and the abundance of neuropeptide-containing fibres was expressed as the percentage of total nerve fibres demonstrated by protein gene product (PG...
