Arachidonic acid (ARA), an important polyunsaturated fatty acid (PUFA), acts as a precursor for eicosanoid hormones, such as prostaglandins, leukotrienes and other biological stone calf puller substances in human and animal bodies.Mortierella alpina is considered to be a potential strain for ARA production.Using agricultural waste as a substrate fo
Influence of plastic tension chord deformation on the shear capacity of prestressed beam elements
The shear strength of prestressed beam elements is of great interest with regard to the evaluation of existing concrete bridges.Accompanying extensive experimental test knipex 88 01 180 series, the adaptation and modification of existing models for the evaluation of the load-bearing capacity also represents an important step.Against this background
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 (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.Several tests
