To study the performance of UHPFRC continuous deep beams with openings, experimental and numerical investigations have been carried out. The test program included seven in addition to one similar solid beam. variables were ratio transverse reinforcement position, height, width opening. results showed that failure mode two-span depends mainly on position size opening shear span. occurs diagonal ...

BACKGROUND The assessment of RBE quantity in the treatment of cancer tumors with proton beams in treatment planning systems (TPS) is of high significance. Given the significance of the issue and the studies conducted in the literature, this quantity is fixed and is taken as equal to 1.1. OBJECTIVE The main objective of this study was to assess RBE quantity of proton beams and their variations...

Introduction: In the last few decades, a lot of monte carlo codes have been introduced for medical applications. this is important because through simulation, we are fully independent of the spectral scattering factor that we are not able measure in real terms. The effect of the radiation energy, the dimension of the radiation field, the sensitive volume of the ion chamber on t...
