in this study , the physical and mechanical properties of polypropylene composites reinforced with bagasse alkaline-sulfite-anthraquinone, soda-anthraqouinone, monoethanolamine-anthraquinone chemical pulps and mechanical pulp (cmp) known as pulp-plastic compostes (ppc) were investigated and the results were compared among ppcs and with polypropylene composites reinforced with bagasse flour know...

[Purpose] This study examined the relationship between toe grip strength and its associated factors by focusing on factors that were suggested to have a relationship with toe grip strength in previous studies, aiming to clarify the factors influencing the toe grip strength of healthy women. [Subjects and Methods] Twelve healthy young women were selected for this study. Their toe grip strength, ...

light weight wood base sandwich panels have some special properties and their most important properties is high mechanical strength with its light weight. these panels can replace instead of traditional structural systems in iran. the purpose of this paper is investigating the mechanical properties of light weight wood base sandwich panels that have made from sunflower stalk wastes and particle...

the current research intends to study the possibility of producing fiber recycled self-compacting concrete (frscc) using demolitions as a coarse aggregate (crushed red brick and crushed ceramic). steel fibers were used in recycled self-compacting concrete (rscc) to improve fresh and hardened properties of this type of concrete. thirty nine concrete mixes were prepared to achieve the aim propose...

a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...

Original scientific paper To enhance underground mining safety, researchers developed high-water and fast-setting cement (HWFSC). HWFSC essentially consists of two components and can be mixed with large quantities of water. To determine its mechanical strength, a series of uniaxial compressive strength tests were conducted on HWFSC specimens with different water-to-solid ratios. Results indicat...

A rationally based procedure has long been needed for assigning design adjustments to Southern Pine lumber treated with waterborne preservative. This paper attempts to develop such a procedure by evaluating a series of models to predict the short-term effects of waterborne preservative treatments on the strength of U.S. Southern Pine lumber. Input data consisted of non-parametric treated to unt...

An improved model for the collision efficiency factor of clusters of oppositely charged spheres has been developed, which accounts for repulsive and attractive interactions that occur at a finite distance from the colliding species, i.e., the so-called "soft" interactions. Trends in measured optimum dosages for rapid aggregation with increasing Debye length (a decrease at particle size ratios b...

OBJECTIVE To characterise and compare the tensile characteristics after multi-proportional blending, to determine the proper blending ratio for new thermoplastic material and to compare its mechanical performance with commercial thermoplastics. METHODS PETG and PC2858 aggregates were blended in five different ratios. Standard specimens of each ratio were molded and tested to determine their m...
