This paper aims to study the effect of coal bottom ash (CBA) as a fine aggregate substitution at high levels on the mechanical properties and microstructure characteristics of concrete. CBA that sourced from a local coal-fired power plant in Vietnam was used to replace the natural sand (NS) in the concrete mixtures at different levels of 0, 30, 50, 70, and 100%.

In kinematic synthesis and analysis of planar mechanisms the designer must define a geometry and set of motions for a design task. This paper will focus on how to determine the forces or torques acting on the planar mechanism by numerical method when acceleration and dynamic properties of the linkage are known.

Natural products have been gaining popularity in recent years as a safe skin-safe alternative solution to synthetic products on the market. In particular, natural ingredients have been found to have skinwhitening properties by inhibiting melanin production and reducing hyperpigmentation. This review provides the analysis of some mechanisms and effectiveness of natural products in achieving even skin tone and reducing the appearance of dark spots.

Resveratrol is a naturally occurring compound with anti-inflammatory properties. However, the protective molecular mechanisms of resveratrol against LPS-induced inflammation have not been thoroughly known. In the present study, we examined the antiinflammatory effect of resveratrol in inflammatory model using murine macrophage-like cell RAW264.7 stimulated with LPS. Resveratrol suppressed the production of inflammatory cytokines in LPS-stimulated RAW264.7 cells with the IC50 value as 17.5 ± 0.7 μM for IL-6, 14.2 ± 1.9 μM for IL-10, and 18.9 ± 0.6 μM for TNF-α.

The results of ultrasonic wave propagation experiments indicated that the presence of steel fibers at a 2% content increased the time of wave propagation. On the other hand, curing conditions, specimen maintenance time, and transmission path distance affected the ultrasonic wave propagation time in high-strength concrete.

To achieve the aim, the first objective is preliminary experiments on preparation of polypropylene blends with silicone elastomer masterbatch and characterize by analysis of mass composition, mechanical properties, and dynamic mechanical properties to investigate any improvement of properties. The silicone elastomer masterbatch will then be substituted with propylene-maleic anhydride graft copolymer waxes or other compatibilizers.
