High energy density physics deals with behavior of matter under extreme conditions of pressure and temperature. Several fields of research involve high energy density: astrophysics, geophysics, inertial confinement fusion (ICF), explosive and impact loading of materials, Z-pinch devices, etc. All of these fields involve one common feature: i.e., concentration of an intense source of energy in a...

We examine in vivo ejection of noncondensed DNA from tailed bacteriophages into bacteria. The ejection is dominantly governed by the physical conditions in the bacteria. The confinement of the DNA in the virus capsid only slightly helps the ejection, becoming completely irrelevant during its last stages. A simple calculation based on the premise of condensed DNA in the cell enables us to estima...

An upgraded spectral motional Stark effect diagnostic has been installed on the gas-dynamic trap (GDT) experiment to enable spatially resolved measurement of |B|. A new low-noise charge-coupled device detector, combined with enhancements of the diagnostic neutral beam, allows single-shot profile measurements. Previously only single-point motional Stark effect measurements were possible, and det...

The diamagnetic flow due to the radial pressure and temperature gradients and the E × B flow due to the radial electric field induce different turbulent momentum fluxes in a tokamak. As a result, when the diamagnetic and E × B flows cancel giving zero net toroidal rotation, there will still be finite momentum transport. This may be particularly important near the plasma–wall boundary where a st...

The possibility of quasi-stable trapping of charged particles of hundreds keV to MeV energy on the frontside Earth magnetosphere is explored in by numerical modeling of the single particle orbits in the geomagnetic field utilizing empirical Tsyganenko magnetic field model. Due to solar wind pressure the remote magnetic field lines on the frontside of the magnetosphere exhibit two minima in the ...

In this paper, an analytical model for quantum confinement electron density in two-dimensional well, has been investigated. order to obtain the exact AlGaN/GaN HEMTs parameters such as density, wave function, band gap, polarization charge, effective mass and dielectric constant, hydrostatic pressure temperature effects are taken into account. It found that decreases with increasing increases pr...

The close confinement of sows in barren environmental conditions gives rise to major public concern for their welfare. Such concern has resulted in EU legislation to ban individual confinement systems for the majority of gestation, and strong pressures to find alternatives to the farrowing crate for lactating sows. Many alternative loose housing systems for dry sows exist, and have been in wide...

Rolling vortices and chaotic swirling are the most visually compelling aspect of smoke. Standard numerical simulation techniques for the animation of smoke suffer from a loss of these vortex patterns due to numerical damping. The majority of methods in computer animation use techniques such as vorticity confinement [3] to re-capture them. In this work, a Lagrangian method is presented which exp...
