Application of X-ray Diffraction Methods and Molecular Mechanics Simulations to Structure Determination and Cotton Fiber Analysis
… for single-crystal structure determinations, fiber diffraction analyses, and in conjunction with molecular modeling of Cellulose IIII. Although each technique is different in its sampling, data acquisition, data treatment, and identification, the common denominator has been the use of x-rays. …

A Modified AISC P -M Interaction Curve for Square Concrete Filled Tube Beam -Columns
… a parametric study is performed using fiber analysis which has been acknowledged as an excellent tool for estimating the sectional strength of CFT members. The axial load at the maximum moment is also evaluated from the fiber analysis. The maximum moment and the axial load at the …

Experimental database, analysis and design of noncompact and slender concrete-filled steel tube (CFT) members
… the experimental test results and additional FEM analysis that address the gaps in the experimental database. The current AISC 360-10 P-M interaction equations are updated using the results from comprehensive parametric studies (conducted using the benchmarked FEM model). Effective stress-strain …

Investigation of organic composition of potential plants as alternative fiber in paper making industry
… have a high potential to become an alternative fiber. The objective of this work was to analysis the chemical composition which are pineapple leaf, corn stalk and Napier grass; to investigate the properties of hand sheet made from those crops; to determine the influence of different pulping …

Nonlinear inelastic analysis of concrete-filled steel tubular slender beam-columns
… new numerical models for the nonlinear inelastic analysis of thin-walled rectangular and circular CFST slender beam-columns incorporating the effects of local buckling, concrete confinement, geometric imperfections, preloads, high strength materials, second order and cyclic behavior. In the …

The effect of three levels of a soy polysaccharide fiber on plasma lipids, fecal fiber, and apparent fiber digestibility
… to four complete liquid diets at four different fiber levels; one without added soy polysaccharide fiber which served as a control. All subjects were rotated. through four, eleven day controlled feeding periods. Complete fecal samples were collected and composited from the last five days of each …

Defining the Role of Elastic Fibers in Tendon Mechanics
… function. Elastin, the main component of elastic fibers, has unique mechanical properties including high extensibility, fatigue resistance, and elasticity; these properties are important for elastin-rich tissues such as blood vessels and the lungs that experience constant cyclic loading. In …

Upgrading biomass by hydrothermal and chemical conditioning
… cellulose hydrolyzed intermediates. Van Soest fiber analysis is incapable of distinguishing those new cellulose-derived polymers from naturally present lignin. Slagging and fouling are two major problems that result from biomass combustion or co-firing with coal, especially for the biomass with …

Identification of quantitative second-harmonic generation imaging metrics for collagenous tissue
… SHG imaging (FT-SHG) to measure the collagen fiber orientation quantitatively. Recently, I expanded this approach by adapting new parameters on two-dimensional (2D) images and significantly broadening the three-dimensional (3D) analysis of 3D-SHG images. Ultimately, these parameters such as …

Characterization of Ultra-High Performance Concrete Tension Behavior Using Different Test Methods
… resulting from the presence of discrete steel fibers in its composition. Furthermore, it exhibits exceptional compressive strength and durability. These remarkable properties are a result of the optimized gradation of cementitious materials, chemical admixtures, and steel fibers that compose …
