In the mammalian auditory nerve physiological recordings revealed that the spontaneous discharge rate of single auditory fibres correlates with the diversity of input-output functions which may be important for intensity discrimination (e.g., Sachs and Abbas, 1974, Liberman, 1978; Winter et al., 1990). In this study we determined if the spontaneous discharge rate of auditory nerve fibres in the...

Four categories of plant food dominated the diet of chimpanzees in Kibale Forest, Uganda: non-fig tree fruits, fig tree fruits, herbaceous piths and terrestrial leaves. Fruit abundance varied unpredictably, more among non-figs than figs. Pith intake was correlated negatively with fruit abundance and positively with rainfall, whereas leaf intake was not influenced by fruit abundance. Piths typic...

Investigation of the mechanisms of muscle adaptation requires independent control of the regulating factors. The aim of the present study was to develop a serum-free medium to culture mature single muscle fibres of Xenopus laevis. As an example, we used the culture system to study adaptation of twitch and tetanic force characteristics, number of sarcomeres in series and fibre cross-section. Fib...

This study concerns the retinotopic organization of the ganglion cell fibres in the visual system of the frog Xenopus laevis. HRP was used to trace the pathways taken by fibres from discrete retinal positions as they pass from the retina, along the optic nerve and into the chiasma. The ganglion cell fibres in the retina are arranged in fascicles which correspond with their circumferential posit...

Using the filamentous actin marker, FITC-conjugated phalloidin, the major muscle systems of adult male and female schistosomes have been examined. The body wall musculature comprises an outer sheath of circular fibres, within which there is a compact layer of short, spindle-shaped longitudinal fibres and a lattice-like arrangement of inner diagonal fibres. Within the oral sucker and acetabulum ...

The Aravalli ranges run along the Sabarkantha district is the ancient region of India, inhibited by tribals living in close vicinity of enriched forest. The present paper contains various ethnobotanical aspects of some plant species used by the tribals for their day-to day requirement. The paper includes the first hand information collected through tribal informants, medicinemen and tribal peop...

Plant-derived natural fibres hold great potential as renewable and sustainable reinforcing elements in structural composites. However, a broader use of fibre composites requires further improvements their mechanical properties, to reach performance comparable carbon fibre-reinforced polymers. In this study, we exploit discontinuous rheologically modified inks controllably reinforce flax-based l...

Aegagropiles are round-shaped conglomerations of Posidonia oceanica debris commonly found along the coasts Mediterranean Sea. This study presents a detailed description composition aegagropiles in terms their internal organisation different layers (and orientation fibres these layers), proportion constituent elements (fibres and minerals) histological (by way microscopic observations) nature al...

1. The photonic-crystal fibres In conventional optical fibres, electromagnetic modes are guided by a phenomenon of total internal reflection on a core-cladding border. The core refractive index is higher than the refractive index of a cladding which is achieved by adequate doping of a central part of the based material [1]. After over 20 years of intense researches on optical fibres, including ...

Abstract In the current research, waste from woollen yarn production was analysed. Woollen as raw material used for of soft thermal insulation mats. Two types mats were produced in a textile plant: thermally untreated and treated. Properties such fibre composition, structure, conductivity treated studied. During composition analysis waste, quantity long, medium length, short fibres determined. ...
