Background. Animal studies have suggested that the temperature of the electrode-tissue interface during radiofrequency catheter ablation accurately predicts lesion size. The purpose of the current study was to evaluate the utility of continuous temperature monitoring during radiofrequency catheter ablation in patients with Wolff-Parkinson-White syndrome. Methods and Results. Twenty patients wit...

A new interaction is derived, which is important only when photons penetrate a hot, sparse electron plasma. When photons penetrate a cold and dense electron plasma, they lose energy through ionization and excitation, through Compton scattering on the individual electrons, and through Raman scattering on the plasma frequency. But when the plasma is very hot and has low density, such as in the so...

Laser fusion simulations are carried out for DT and D- He pellets by using a hydrodynamic code including heating from all charged reaction products and neutrons. It is shown that the inclusion of the side reactions and heating from all reaction products in the fuel pellets have an appreciable effect on the plasma temperature, the ICF drive energy requirement, fusion gain and the ignition c...

Background: Radiofrequency has been proven to penetrate deeper than optical light sources independent of skin color allowing a safer treatment for the Asian skin type. Many studies have indicated the efficacy of various types of devices, but have not included a sufficient objective evaluation. Multisource radiofrequency uses multiple phase controlled radiofrequency generators with real time imp...

The problem of targeted delivery and controlled release of a chemical payload in difficult-toaccess microstructured environments such as living tissues or porous soil is considered. Composite microcapsules consisting of the thermo-responsive hydrogel poly-Nisopropylacrylamide (PNIPAM) with dispersed iron oxide nanoparticles have been prepared by w/o emulsion polymerization. The microcapsules ar...

A set of constraints is derived for the operating characteristics of tokamak power reactors which are bulk heated by electron cyclotron resonance heating (ECRH). Four heating modes are considered: ordinary wave heating at the electron cyclotron frequency, 0, and at the second harmonic frequency, 20, and extraordinary wave heating at 0 and at 20. For ordinary wave heating at 1, which appears to ...

Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...

Abstract Helicon plasma sources operating with hydrogen or deuterium might be attractive for fusion applications due to their higher power efficiency compared inductive radiofrequency sources. In recent years, the resonant antenna ion device (RAID) has been investigating physics of helicon plasmas and possibility employing them produce negative ions heating neutral beam injectors (HNBs). Herein...
