Metal implants produce susceptibility artefacts in magnetic resonance imaging. We have explored the effects of scaphoid screw characteristics and orientation on MR susceptibility artefact. Titanium alloy, smallness and longitudinal alignment with the z-axis of the main magnetic field reduce the size of the susceptibility artefact.
The interactions of praseodymium(III) and neodymium(III) with nucleosides and nucleotides have been studied in different stoichiometry in water and water-DMF mixtures by employing absorption difference and comparative absorption spectrophotometry. The 4f-4f bands were analysed by linear curve analysis followed by gaussian curve analysis, and various(More)
Photo-/thermoresponsive surfaces that consist of thin layers of crosslinked poly(N-isopropyl acrylamide) functionalized with photochromic spirobenzopyran grafted from the cyclic olefin copolymer substrates are reported. These films act as intelligent hybrid films whose wettability can be reversibly manipulated by simple incandescent light irradiation or(More)
