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 powder (VPP) was investigated for use as a supplementary cementitious material.High-strength concrete Wheels (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%) to produce different concrete mixtures.Severa

Diversity of the Chemical Profile and Biological Activity of Capsicum annuum L. Extracts in Relation to Their Lipophilicity

Ethanol extracts of two types of pepper (sweet and hot) were separated into fractions with increasing lipophilicity.After drying the extracts and fractions, their chemical composition, anti-radical activity in the DPPH radical system, and cytotoxic activity against Tonneau Cover PC-3 and HTC-116 cells were determined.A detailed qualitative analysis
