DURABILITY AND STRENGTH CHARACTERISTICS OF HIGH-STRENGTH CONCRETE INCORPORATED WITH VOLCANIC PUMICE POWDER AND POLYPROPYLENE FIBERS

Durability and strength characteristics of high-strength concrete incorporated with volcanic pumice powder and polypropylene fibers

In this paper, the partial replacement of volcanic pumice Course a pied - Homme - Vetements - Collant - Long powder (VPP) was investigated for use as a supplementary cementitious material.High-strength concrete (HSC) was prepared using two sets of VPP (10% and 20%) incorporated with three sets of polypropylene fiber (PF) (0.20%, 0.35%, and 0.50%) t

Effect of the amount of SiC, number of strokes, and applied load on the reciprocating wear behavior of Al-SiC composites

The wear behavior of Al/SiC composites prepared by stir casting technique is investigated to find out the effects of the weight percentage Solid of SiC, load, and the number of strokes on a shaper machine.Metal matrix composite (MMC) pins are prepared with different weight percentages of SiC (10%, 15%, and 20%).The tests are carried out with differ

Contact-dependent inhibition of HIV-1 replication in ex vivo human tonsil cultures by polymorphonuclear neutrophils

Summary: Polymorphonuclear neutrophils (PMNs), the most abundant white blood cells, are recruited rapidly to sites of infection to exert potent anti-microbial activity.Information regarding their role in infection with human immunodeficiency virus (HIV) is limited.Here we report that addition of PMNs to HIV-infected Measuring Cups cultures of human
