Rotation measures in galaxy clusters from background and embedded sources: estimating the cluster magnetic fields
Rotation measures (RMs), derived using polarized radio sources embedded in clusters, are commonly used to estimate magnetic field strengths in intra-cluster media(ICMs). To obtain these field values, assumptions are often invoked that involve: no RM contributions from the RM source, adequate …

A comparison between muscle energy technique and high velocity low amplitude thrust technique on gross trunk rotation range of motion
… of HVLA and MET for increasing gross trunk rotation range of motion (ROM). Ninety volunteers (age range 18-40) were randomly assigned to either treatment (MET or HVLA) or control groups, and blinded pre-, immediately post- and thirty minutes post-active trunk rotation measures were recorded …

Constraining the Magneto-Ionic Environment of Galactic Supernova Remnants
… tools for doing so is the observation of rotation measures (RMs), a quantity describing the effects of Faraday rotation on polarised radiation that depends on the magnetic field threading the volume of electron gas the radiation travels through. By calculating RMs from polarised sources at …

Radio-polarimetric observations of gravitational lenses
… and used contemporary algorithms to estimate rotation measure values of the lens sample. In addition, we proposed a framework for evaluating the performance of fringe-fit methods in the low SNR regime using bootstrap resampling. Our 43 GHz maps of B0218+357 provide the highest-resolution …

Parsec-scale polarization of the jet in quasar 4C 71.07
… number of factors; external and internal Faraday rotation, unresolved changes in jet direction ("wiggles"), asymmetric magnetic field structures and gravitational lensing. Lensing rotates the image, leaving the polarization orientation unchanged, even when the lensing is sufficiently weak that …
