We discuss the first applications of our newly developed Monte Carlo event generator SOPHIA to multiparticle photoproduction of relativistic protons with thermal and power law radiation fields. The measured total cross section is reproduced in terms of excitation and decay of baryon resonances, direct pion production, diffractive scattering, and non-diffractive multiparticle production. Non–dif...
This paper reports the preliminary findings of novel methodologies employed for the detection of charged particles using a presumed axion particle generator. Axions are believed to be light neutral pseudoscalar particles produced through the Primakoff effect. Pseudoscalars are defined as a scalar quantity that changes sign when the sense of the orientation of the coordinate system is changed. I...
A 70-year-old woman had a single-chamber implantable cardioverter-defibrillator (ICD) inserted four years previously for ventricular sustained tachycardia caused by ischaemic heart disease. She was admitted for assessment of grade II dyspnoea and muteness of the ICD. Chest X-ray showed that the generator had been rotated clockwise through almost 180°, and the lead displaced and fully wrapped ar...
(A) Chest X-ray after pacemaker implantation (A). (B) Four days later, chest X-ray showed the displacement of the leads into the right atrium and the superior vena cava, with both the leads being wrapped around the pacemaker generator. (C) A few months later, a repeat chest X-ray showed a similar displacement of both the leads. A 67-year-old woman who underwent pacemaker implantation 4 days ago...
With the aim of clinical applications of X-ray phase imaging based on Talbot-Lau-type grating interferometry to joint diseases and breast cancer, machines employing a conventional X-ray generator have been developed and installed in hospitals. The machine operation especially for diagnosing rheumatoid arthritis is described, which relies on the fact that cartilage in finger joints can be depict...
The intensity of prompt gamma-ray was measured at various depths from chlorine-contaminated silica fume (SF) concrete slab concrete specimens using portable neutron generator-based prompt gamma-ray setup. The intensity of 6.11MeV chloride gamma-rays was measured from the chloride contaminated slab at distance of 15.25, 20.25, 25.25, 30.25 and 35.25cm from neutron target in a SF cement concrete ...
