The atom–bond connectivity (𝐴𝐵𝐶) index of a graph 𝐺 is defined as the sum over all pairs of adjacent vertices 𝑢, 𝑣, of the terms,[d (u)+ d (v)− 2]/[d (u) d (v)], where 𝑑 (𝑣) denotes the …
Medical linear accelerators (linacs) are the most frequently applied radiation therapy machines in the locoregional treatment of cancers by producing either high-energy electron …
A new approach combining UV and thermal treatments has been studied for improved UV dosimetry of CR-39 polymeric detector films. Prior to thermal annealing, the detector films …
Monte Carlo method has been used to determine the efficiency for proton production and to study the energy and angular distributions of the generated protons. The ENDF library of …
A systematic study on the measurement of neutron spectra emitted from the interaction of protons of various energies with a thick beryllium target has been carried out. The …
