A semi-empirical formula allowing the extrapolation of the calibration curve towards higher energies. 2. Calibration by means of high energy gamma rays from (n,γ) or (p,γ) reactions produced in accelerators or nuclear reactors. These methods are time consuming, expensive and often inaccurate. ...
It was an absolute dream not to have to move or remove the mask to change the size of the beam of light—all I needed to do was dial in the aperture size I wanted. I did have to change the position closer to my camera for super macro, but apart from that, I did not need to ...
At 2 s after the cease of irradiation, the long-persistent luminescent sheet was kept close to the culture dish. Interestingly, we observe that the survival of P. aeruginosa PAO1 is associated with the X-ray irradiation time of the sheet, and around 39.6% viability can be maintained for...

Room temperature X-ray diffraction data collection forTthSHMT crystals was carried out on a Rigaku HighFlux HomeLab instrument equipped with a MicroMax-007 HF X-ray generator, Osmic VariMax optics, and a DECTRIS Eiger R 4 M detector at Oak Ridge National Laboratory. The data were indexed an...
The calculations from which FIGS. 9 to 12 were derived were carried out using wave optics based on the Kirchhoff formula for propagation of electromagnetic radiation. These involve fairly intensive numerical integration. Both absorption and phase effects are considered. As can be seen, the curves ar...
