in 2007, research was carried out to determine the type and amount of asbestos fibers in a croatian factory with a long history of making asbestos-containing products.since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. in the environment, asbestos fibres are inactive and naturally resist biodegradation. in time, fibres can only be gr...

Nano-indentation instrumented tests are carried out at shallow depths on PAN-based and MPP-based carbon fibres. Indentation moduli obtained by performing the ten different measured orientations with respect to fibre axis. They used identify elastic constants of fibres, assuming a transversely isotropic behaviour, minimising cost function between estimated values. Inconstancies identified in-pla...

Normal ascending aorta functions as an elastic reservoir to enhance arterial flow. It stores energy during systole and dissipates it during diastole. The medial layer of the aorta consisting of elastin, collagen, and smooth muscle cells ensures the elasticity of the aortic wall. The ascending segment of the aorta is more elastic than the descending segment, due to its greater concentration of e...

THE ability to initiate and terminate micturition in a normal fashion and to maintain continence between voidings depends upon an intact corticoregulatory tract and an adequate urinary sphincter (Lapides, 1962). It has been demonstrated (Lapides et al., 1960 a ; Woodburne, 1960) that the urinarysphincter is a tubular structure (Fig. I ) approximately 3 cm. long in both the young male and female...

Elastic fibres play a key role in bodily functions where fatigue resistance and elastic recovery are necessary while regulating phenotype, proliferation migration cells. While vivo created at late foetal stage, major obstacle the development of engineered tissue is that human vascular smooth muscle cells (hVSMCs), one principal elastogenic cells, unable to spontaneously promote elastogenesis vi...

The equine biceps brachii (biceps) initiates rapid limb protraction through a catapult mechanism. Elastic strain energy is slowly stored in an internal tendon and is then rapidly released to protract the forelimb. The muscle fibres are short, have little scope for length change and can therefore only shorten slowly compared with the speed at which the whole muscle must shorten, which makes them...
