FAST RADIO BURSTS AS STANDARD CANDLES FOR COSMOLOGY

Fast radio bursts as standard candles for cosmology

Recently, fast radio bursts (FRBs) have become a thriving field in astronomy and cosmology.Due to their extragalactic and cosmological origin, they are useful to study the cosmic expansion and the intergalactic medium (IGM).In the literature, the dispersion measure Furniture (DM) of FRB has been considered extensively.It could be used as an indirec

Finite element analysis in defining the optimal shape and safety factor of retentive clasp arms of removable partial denture

Bacground/Aim.Retentive force of removable partial denture (RPD) directly depends on elastic force of stretched retentive clasp arms (RCAs).During deflection RCA must have even stress distribution.Safety factor is the concept which can be applied in estimating durability and functionality of RCAs.This study was based on analyzing properties of clas
