Model and simulation investigation of the whole process of high-current vacuum arc burning

AIP Advances, 2021
With the development of the power industry and the increase in the capacity of power systems, vacuum switches have been developed rapidly. The distribution characteristics of the vacuum arc can reflect the working conditions of the vacuum switch.

Analysis of Application of Plasma Ignition in Closed Vessel Tests

Energies, 2021
This paper presents the results of a comparative investigation into the effects of the ignition method on the ballistic properties of three types of propellants: a single-base propellant, a double-base propellant and a low vulnerability (LOVA) propellant,

Micafungin Concentrations in the Plasma and Burn Eschar of Severely Burned Patients [PDF]

Antimicrobial Agents and Chemotherapy, 2012
ABSTRACT Micafungin concentrations in plasma and burn eschar after daily intravenous infusion (1 h) of micafungin (200 to 300 mg) were investigated for six patients with severe burns. Micafungin treatment was initiated more than 72 h after the burn injuries.

Closed Vessel Investigation of Propellant Ignition Process with Using Capillary Plasma Generator [PDF]

Problemy Mechatroniki, 2015
Previous published results of closed vessel investigations indicated that classical primers (electric or percussion with black powder bedding) when used with LOVA propellants cause unstable burning, deflagration or even lack of ignition. Capillary Plasma

A kinetic study of fusion burn waves in compressed deuterium–tritium and proton–boron plasmas

Frontiers in Physics
We present particle-in-cell simulations with Monte Carlo collisions of fusion burn waves in compressed deuterium–tritium and proton–boron plasmas. We study the energy balance in the one-dimensional expansion of a hot-spot by simulating Coulomb collisions,

Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Fast ion relaxation in ITER mediated by Alfvén instabilities

Nuclear Fusion
We address the critical issue for future burning plasmas of whether high-energy fusion products or auxiliary heating-beam ions will be confined for a sufficiently long time to compensate for thermal plasma energy losses.

Nonlinear equilibria and transport processes in burning plasmas

New Journal of Physics, 2023
In this work, we put forward a general phase space transport theory in axisymmetric tokamak plasmas based upon the concept of zonal state (ZS). Within this theoretical framework, the ZS corresponds to a renormalized plasma nonlinear equilibrium ...

Quantitative characterization of helium in the ITER-like co-deposition layer by laser-induced breakdown spectroscopy

Nuclear Materials and Energy, 2023
As a product of the D-T burning plasma in tokamak fusion reactors, helium (He) ash would be retained in plasma-facing components like the first wall and divertor, harming the stable operation of burning plasma. The quantitative monitoring of He retention
