Natural fibers (NFs) have recently been the center of attention among researchers due to their low cost, availability, ease manufacture, and potential environmental friendliness as reinforcing agents in composites. The present work deals with mechanical behavior palm fiber-reinforced epoxy-based composites different weight percentage (Wt.%) ratios, ranging from 6% 31.6%. Glass hybrid were also ...

The cat hindlimb contains several long, biarticular strap muscles composed of parallel muscle fascicles that attach to short tendons. Three of these muscles--sartorius, tenuissimus, and semitendinosus--were studied by dissecting individual gold-stained fibers and determining the surface distribution of acetylcholinesterase-stained end-plate zones. In each muscle, fascicles were composed of musc...

Equine digital flexor muscles have independent tendons but nearly identical mechanical relationship to the main joint they act upon. Yet these muscles have remarkable diversity in architecture, ranging from long, unipennate fibers (‘short’ compartment of DDF) to very short, multipennate fibers (SDF). To investigate the functional relevance of the form of the digital flexor muscles, fiber contra...

Most marine mammals are hypothesized to routinely dive within their aerobic dive limit (ADL). Mammals that regularly perform deep, long-duration dives have locomotor muscles with elevated myoglobin concentrations that are composed of predominantly large, slow-twitch (Type I) fibers with low mitochondrial volume densities (V(mt)). These features contribute to extending ADL by increasing oxygen s...

2014 The mechanical properties of random short carbon fiber composites have been studied experimentally in relation with the electrical properties (continuity) in three different states : 1) fibers in a hard expoxyde matrix, 2) fibers in a well formed gel, 3) fibers sediment in a viscous liquid. Although there is no precise correlation between the electrical percolation threshold and the contin...
