Recent foodborne illness outbreaks associated with the consumption of low moisture foods such as spices have emphasized concerns over microbial food safety. In-package RF pasteurization method was evaluated for inactivation Salmonella enterica in dried basil leaves. Samples were packed polystyrene bottle provided a steam venting film and either positioned vertically (electrode gap = 16 cm) or h...

Objective: To determine the safety and the efficacy of lumbar spine radiofrequency neurotomy performed in the presence of pedicle screws in patients with chronic low back pain. Methos: Retrospective practice audit. Review of charts of all patients who underwent lumbar radiofrequency neurotomy in the presence of pedicle screws. Patients were tested with a minimum of two controlled medial branch ...

The dynamics of fast gas heating in a high power microwave discharge in air, is investigated in the framework of FDTD simulations of the Maxwell equations coupled with the fluid simulations of the plasma. It is shown that, an ultra-fast gas heating of the order of several 100 Kelvins occurs in less than 100 ns. The main role in the heating is played by the electron impact dissociation of , diss...

The aim of this paper is to determine the possibilities of modern radiofrequency (RF) technology and the usefulness of abdominal and thoracic parenchymatous organs in surgery. Investigation was made on 17 patients with 125 RF energy realized cycles (an average of 7.35 per one pt.) and the average time heating coagulative necrosis of 42.6 minutes (maximum to 80 minutes). There was one complicati...

[Purpose] This study aimed to compare the efficacy of radiofrequency diathermy with that of microwave diathermy in combination with intra-articular injection of hyaluronic acid into the knee of patients with osteoarthritis (OA). [Subjects] A total of 17 patients with knee OA were enrolled. The participants were randomly divided into two groups: a radiofrequency diathermy group (RF group, 9 subj...

PURPOSE The goal of this study is to increase patient safety in parallel transmission (pTx) MRI systems. A major concern in these systems is radiofrequency-induced tissue heating, which can be avoided by specific absorption rate (SAR) prediction and SAR monitoring before and during the scan. METHODS In this novel comprehensive safety concept, the SAR is predicted prior to the scan based on pr...
