The Bubble regime of electron acceleration in ultra-relativistic laser plasma is considered. It has been shown that the bubble can produce ultra-short dense bunches of electrons with quasi-monoenergetic energy spectra. The first experiment in this regime done at LOA has confirmed the peaked electron spectrum (J. Faure, et al., submitted, 2004). The generated electron bunch may have density an o...
A new technique is described for the isochoric heating (i.e., heating at constant volume) of matter to high energy-density plasma states (>10(5) J/g) on a picosecond time scale (10(-12)sec). An intense, collimated, ultrashort-pulse beam of protons--generated by a high-intensity laser pulse--is used to isochorically heat a solid density material to a temperature of several eV. The duration of he...
Intense ultrashort laser pulses are known to generate high-density, high-temperature plasma from any substrate. Copious emission of hot electrons, from a solid substrate, results in strong electrostatic field that accelerates the ions with energies ranging from a few eV to MeV. Ion spectrometry from laser–plasma is convolved with multiple atomic systems, several charge states and a broad energy...
In HeLa cells the assembly of modified vaccinia virus Ankara (MVA), an attenuated vaccinia virus (VV) strain, is blocked. No intracellular mature viruses (IMVs) are made and instead, immature viruses accumulate, some of which undergo condensation and are released from the cell. The condensed particles may undergo wrapping by membranes of the trans-Golgi network and fusion with the plasma membra...
Abstract My career has included astrophysics and space physics, always with a theoretical emphasis. first papers calculated nuclear reaction rates in dense stars, particularly neutron but I branched out to other areas or astrophysics. However, most of my work was the plasma physics magnetosphere ionosphere Earth. The central theme is Rice Convection Model (RCM). This paper very briefly describe...
The basic physics of nonrelativistic and electromagnetic ion stopping in hot and ionized plasma targets is thoroughly updated. Corresponding projectile-target interactions involve enhanced projectile ionization and coupling with target free electrons leading to significantly larger energy losses in hot targets when contrasted to their cold homologues. Standard stoppping formalism is framed arou...
Abstract Background and Objectives The plasma industry started during World War II with the need for Plasma Derived Medicinal Products (PDMP). About 30 major plasma products are now commercially available, the most important of which are albumin, coagulation factors and immunoglobulin. Demand for these products is still growing, and these products have become particularly important not only in ...
Interaction phenomena of intense ion and laser radiation with matter have a large range of application in different fields of science, from basic research of plasma properties to application in energy science. The hot dense plasma of our neighbouring star the Sun provides a deep insight into the physics of fusion, the properties of matter at high energy density, and is moreover an excellent lab...
Ileal lining cells of the suckling rat possess an "apical endocytic complex" capable of sequestering intact protein from the intestinal lumen. The complex consists of a network of invaginations of the apical plasma membrane, a number of subjacent small vesicles, and a giant supranuclear vacuole. The first two components initially incorporate material from the intestinal lumen and then transfer ...
McCoy cell cultures infected with the agent of ovine chlamydial polyarthritis were examined with the electron microscope. The agent was seen as small dense particles (250 to 450 nm) with an eccentric nucleoid and a multilaminated cell wall, as large (800 to 1,200 nm) granular particles surrounded by two unit membranes and as intermediate particles. Replication, which occurred throughout the cyt...
