Human auditory perception of pulses of radiofrequency (RF) energy is a well-established phenomenon that is dependent upon the energy in a single pulse and not on average power density. RF-induced sounds can be characterized as the perception of subtle sounds because, in general, a quiet environment is required for the sounds to be heard. The sound is similar to other common sounds such as a cli...
Study Design. Quasiexperimental study. Objective. To investigate whether radiofrequency treatment can preclude the need for spinal surgery in both the short term and long term. Background. Radiofrequency is commonly used to treat lumbosacral radicular pain. Only few studies have evaluated its effects on surgical indications. Methods. We conducted a quasiexperimental study of 43 patients who had...
Tantalum oxide is a compound with attractive properties and important applications in optoelectronis. It has a high refractive index and a good thermal and chemical stability. Tantalum oxide thin layers have been deposited by laser ablationpulsed laser deposition (PLD) and radiofrequency assisted pulsed laser ablation (RF-PLD) starting from a Tantalum metallic target in oxygen atmosphere. In th...
