Re-appraisal and extension of the Gratton-Vargas two-dimensional analytical snowplow model of plasma focus evolution in the context of contemporary research

, 2013
Recent resurgence of interest in applications of dense plasma focus and doubts about the conventional view of dense plasma focus as a purely irrotational compressive flow have re-opened questions concerning device optimization.

On the failure of neutron yield scaling in the dense plasma focus

Physics of Plasmas, 2023
The observed scaling of neutron yield in the dense plasma focus (DPF) as the fourth power of the current in the plasma was the principal driver of the growth of DPF research in its early days. Subsequent discovery of failure of this scaling law was also the principal reason for its abandonment by major laboratories.

Prominence seismology using the period ratio of transverse thread oscillations [PDF]

, 2015
The ratio of the period of the fundamental mode to that of the first overtone of kink oscillations, from here on the "period ratio", is a seismology tool that can be used to infer information about the spatial variation of density along solar magnetic ...

Atmospheric Influence on the Structural and Mechanical Properties of TiN Coating Deposited on NiTi Shape Memory Alloy via Mather-Type Dense Plasma Focus [PDF]

Journal of Advanced Materials in Engineering
Introduction and Objectives: Nickel-titanium alloys have poor hardness and tribological properties. There is a possibility of loosening caused by wear while using these alloys for medical applications such as artificial bone joints.

Oxidative Stress, Atherogenic Dyslipidemia, and Cardiovascular Risk

Biomedicines, 2023
Oxidative stress is the consequence of an overproduction of reactive oxygen species (ROS) that exceeds the antioxidant defense mechanisms. Increased levels of ROS contribute to the development of cardiovascular disorders through oxidative damage to ...

Dense Plasma Focus Modeling

, 2016
The mechanisms for pinch formation in Dense Plasma Focus (DPF) devices, with the generation of high-energy ions beams and subsequent neutron production over a relatively short distance, are not fully understood. Here we report on high-fidelity 2D and 3D numerical magnetohydrodynamic (MHD) simulations using the LA-COMPASS code to study the pinch ...
