The fiber characteristics (i.e., the fiber type, morphology, and dimension) and polymer melt flow index (MFI) significantly affected mechanical properties of sugarcane fiber/HDPE composites. The length and diameter of sugarcane fibers followed a lognormal distribution before and after compounding. The long fibers had a significant reduction in the dimension and aspect ratio during compounding. ...

Abstract In view of strengthening reinforced PTFE/Al composite system, based on the fiber mechanism and cross-scale theory material, research about material component system design, mechanical property design microstructure optimization was carried out by means theoretical analysis numerical simulation. The properties with different carbon content aspect ratio were studied using short fiber.

TO THE EDITOR: Arentson-Lantz et al. (1) report that 14 days of bed rest (BR) induces a profound decline in muscle strength ( 13%) and fiber cross-sectional area (CSA) ( 24%) in middle-aged adults. More importantly, they report that short-term disuse-induced muscle fiber atrophy is accompanied by a reduction in satellite cell content ( 38%). These results are in sharp contrast with other human ...

The aim of this study was to assess the relationships between human muscle fiber hypertrophy, protein isoform content, and maximal Ca(2+)-activated contractile function following a short-term period of resistance exercise training. Six male subjects (age 27 +/- 2 yr) participated in a 12-wk progressive resistance exercise training program that increased voluntary lower limb extension strength b...

For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...

despite the numerous health effects of the dietary fibers, the amount of the fiber in the diet is generally lower than the recommended value. therefore, increasing the fiber content of the foods particularly those of high consumption can compensate for the shortage of the fiber in the diet. however, it seems a difficult task since increasing the fiber content can have adverse effects on product...

Fiber dimensions and lignin and cellulose content of various highly productive, non-wood plants and agricultural residues were examined to assess their suitability for paper production. Plants like kenaf (Hibiscus cannabinus L.) and giant reed (Arundo donax L.) internodes gave very good derived values, especially slenderness ratio, which is directly comparable to some softwood and most hardwood...

Abstract : The effect of a bond failure and its extent is studied on stress concentration in long fibers as well as stress distribution in short fibers and their surrounding matrix bays. The material is assumed to be a finite width hybrid composite lamina which is subjected to a tensile load of magnitude "P" at infinity. The surrounding matrix is assumed to take only shear (shear-lag theory). T...
