The problem of error analysis is one which presents itself in any experimental setting. One measures some quantities in an experiment, and through calculation obtains a number which hopefully describes some important facet of Nature. From a series of measured numbers one should be able to divine a ‘rule of Nature’ and gain a true understanding about what is going on around us everyday. Unfortun...

This paper describes a polarized-light imaging interferometer to measure the rotation field of reflecting surfaces. This setup is based on a homemade prism featuring a birefringence gradient. The arrangement is presented before focusing on the homemade prism and its manufacturing process. The dependence of the measured optical phase on the rotation of the surface is derived, thus highlighting t...

objective(s):  denaturing high performance liquid chromatography (dhplc) is a high throughput approach for screening dna sequence variations. to assess oven calibration, cartridge performance, buffer composition and stability, the wave low and high range mutation standards are employed to ensure reproducibility and accuracy of the chromatographic analysis. the purpose of this study was to provi...
