Background and objectives: Astragalus is one of the most abundant genera of flowering plants in Iran.There are a few reports on phytochemical investigation of this valuable genus.Saponins, flavonoids and polysaccharides have been reported as the most important metabolites in Astragalus species.In the present research, we aimed to identify the forem
Abstract We report a sensing platform for surface-enhanced infrared absorption (SEIRA) spectroscopy, based on Fano metamaterials (FMMs) on dielectric nanopedestals.FMMs consist of two parallel gold (Au) nanorod antennas, with a small horizontal coupler turbo air m3f24-1 attached to one of the nanorod antenna.When placed on SiO2 dielectric nanopedes
In this study, the key findings of evaluating laser beam welding parameters on the multi-layered structure of 6061 aluminum alloys fabricating by accumulative roll bonding process are reported, considering fostering mechanical properties concerning the influence of filler metal and welding 100w products speed on the weld bead quality by taking into
One of the authorities of the Constitutional Court (MK) is to resolve disputes over general election results.In the 2024 presidential election, the presidential candidate pair Anies Baswedan-Muhaimin and the Ganjar-Mahfud sofia barclay sexy pair filed a lawsuit with the Constitutional Court.This study uses normative research.The results show that m
As low-cost, widely distributed and easily accessible renewable clean energy, solar energy has attracted more and more attention.Direct absorption solar collectors can convert solar energy into heat, but their efficiency is closely related to the absorption performance of the working fluid.In order to improve the absorption efficiency of direct abs
