Irradiation effects of X-rays (45 min and 90 min) on track etch parameters of Lexan polycarbonate detectors have been studied with respect to structural behavior using Fourier transform infrared spectroscopy (FTIR) spectroscopy. Pre-exposure and post-exposure of X-rays bring significant changes in ...
Chest X-ray is also an approach commonly used by programmes for triage. Therefore, we also considered X-ray in combination with other triage algorithms as a tool to ensure all patients with X-rays suggestive of TB would receive a diagnostic test [26, 27]. We modelled an X-ray algorithm ...
(3) Third, we reanalysed data while excluding all patients who did not have chest X-rays or blood cultures taken, which also gave similar results as in the main analysis. (4) Finally, we conducted an analysis restricted to patients who had an ICD-10 discharge diagnosis of acute LRTI. ...
Advanced environmental control as a key component in the development of ultrahigh accuracy ex situ metrology for x-ray optics The advent of fully coherent free-electron laser and diffraction-limited synchrotron radiation storage ring sources of x-rays is catalyzing the development...

(M) X-rays have a positive impact in the world because it is painless. (E) " Now with the new technology of the ProOne X-Ray machine being used at Edgewater Pediatric Dentistry, you and your child can have a more pleasant –and safer- visit!" (Edge water Dentist). (A) Many child...
Our X-ray burst model calculations are intended to serve as a benchmark for future model comparisons and sensitivity studies, as the complete underlying nuclear physics is fully documented and publicly available. 展开 关键词: nuclear reactions, nucleosynthesis, abundances, X-rays: bursts ...
In recent years, exciting developments have taken place in the identification of the role of cosmic rays in star-forming environments. Observations from ra
Recent observations of characteristic x rays produced by higher-energy (30-80 MeV) alpha particles are compared to previous measurements and to theoretical calculations based on the impulse approximation. These data are found to be in agreement with theory. The effects of choice of fluorescence yield...
After postdoc research at Stanford University, he returned to Lund and started a research group on soft x-rays. Since 1997, he is full professor in biomedical physics at the Royal Institute of Technology (KTH), Stockholm. Here, he has built a cross-disciplinary research group in x-ray ...
