Abstract:

<p>This paper concerns the influence of moving an auxiliary limiting cylinder in X-Y directions on the electrostatic field and corona onset voltage of the dual electrode system employed in the electrostatic filtration process resulting in a “Tri-electrode” system. The Tri-electrode system is applied in order to control the field around the ionized wire and on the ground plate. Accurate calculation of the electrostatic field is obtained using the charge simulation method coupled with genetic algorithms. The calculated field values are utilized in computing the corona onset voltage of the

This study was conducted to characterize the alterations in serum ionized calcium induced by contrast media (CM) and to determine the cause of the change. Fresh human blood samples as well as an electrolyte solution (ES) containing 1.2 mM calcium ions were diluted with CM and alterations in ionized calcium were measured using an electrometer. The CM tested were diatrizoate, iopamidol, iohexol, ioxaglate, isotonic saline, Na2-Ca-EDTA and pure meglumine. When CM were mixed with blood, ionic CM produced a greater decrease in ionized calcium than nonionic CM or saline. When mixed with ES, a signif

AbstractFollowing the arguments presented by Mansuripur [Opt. Express, vol. 16, 2008, pp. 14821–14835], we suggest a form for the macroscopic electromagnetic stress tensor appropriate for ionized media. The generalized Lorentz force includes the effects of polarization forces as well as those on the free charge and current densities. The resulting tensor is written in terms of the fields D, B, E, and H. Its expression for a fully ionized medium subject to an external electromagnetic field is discussed, as are the plasma conservation equations. An apparatus is suggested for its experimental dis

The dominant natural electromagnetic (EM) radiation in the extremely low frequency (ELF) range is due to global lightning activity. Radio waves of ELF band traveling along the surface of the ground are able to circle the globe and return to the starting point. Schumann Resonances (SR) are the EM phenomena which occur in the cavity formed by the conducting Earth and the ionosphere, with peak frequencies close to 8, 14, 20, 26 Hz, etc. The spectral characteristics of the SR modes are defined by their resonant mode amplitudes, center frequencies and half-widths.

Some of the core material is entrained and accelerated above the local sound speed, ensuring that shocks are present at the interfaces with the undisturbed cloud.

Deformation of a Gaussian beam is observed when it propagates through a plasma. Self-focusing of the beam may be observed when the intensity of the laser increases the index of refraction of plasma gas. Due to the difficulties in solving the nonlinear partial differential equation in Maxwell's wave equation, a numerical technique has been developed in favor of the traditional analytical method. Result of numerical solution shows consistency with the analytical method. This further suggests the validity of the numerical technique employed.

Abstract:

Abstract In principle, the phenomenological description of electromagnetic wave propagation in plasmas can be regarded as a chapter of the electrodynamics of material media. Plasmas differ from usual materials in several respects, however, which can be traced to the fact that all charge carriers are free. Hence the distinction between polarization and conduction current, which is of fundamental importance for non-ionized media, becomes irrelevant. On the other hand, the influence of the thermal motion of ions and electrons on the propagation of electromagnetic waves cannot always be neglected; as a consequence spatial dispersion, which is a rather exotic phenomenon in ordinary dielectrics or metals, plays an important role in plasmas. Finally, a magnetized plasma is anisotropic, but the resulting birefringence is of a different nature from that of typical crystals. In this chapter, therefore, we will introduce the electrodynamics of plasmas from a macroscopic, or phenomenological, point of view. We will limit ourselves to the case of linear wave propagation, although a plasma is, strictly speaking, a nonlinear medium. Nonlinear effects will be briefly considered in Chapter 11.

Abstract:

Abstract Organic compounds are sensitive to radiation by virtue of the irreversible chemical processes which take place when covalent bonds, in this case mainly C-C, C-O, O-H and C-H bonds, are excited or ionized by irradiation. Frequently, the bonds are ruptured and the reactive fragments then form new compounds, a process known as radiolysis. We have not met this process in our discussion of electronic devices and optics because the inorganic materials which largely make up such devices do not undergo decomposition in this way. The exceptions are radiolytic hydrogen in some Metal-Oxide-Semiconductor structures and radiolytic halogen in some halide salts. Organics in the form of plastics now play an indispensable role in conventional product engineering, examples being moulded structures, packets, fibre-reinforced boards, insulating sheathing, insulating and hydraulic oils, and so on. In more advanced engineering, organics, again mainly polymeric, are also extremely diverse, examples being photoresists, protective, encapsulating and passivating layers, inert binders for pigments and photographic media, active media for sensing light, force or temperature and in the millennium some active electronic switches and light emitters. Further, there is a huge volume and variety of non-polymeric, often finely-divided organic solid which come into our lives as foods, drugs, papers, dyes, explosives, and myriad natural products. Finally, organic liquids play a part in most of the above fields, including drinks, solvents, synthetic intermediates, lubricants, and insulating oils. An unexpected proportion of this diverse list may be exposed to radiation in industrial processes. For example, plant material may be used as a filler in radiation reprocessing, foods are irradiated as a preservation measure, and a toxic material such as dioxin vapour may be irradiated to destroy it. The diversity of the above list of materials makes it clear that, while all are likely to have some reactions in common (e.g. generation of hydrogen), it is a large task to list and categorize accurately the changes in physical parameters or to develop broad prediction schemes in the same way as for silicon devices.

Abstract:

This chapter explains how non-aqueous solvents are used as media for carrying out reactions and as carriers to deliver solutes to their point of use. It looks at the various classes of reaction in which the solvent can participate, such as acid-base reactions that can take place in the gas phase. It also talks about the acid-base reactions in water, which have been extensively studied to provide an insight into the nature of acidity. The chapter discusses acid as a substance that either alone or through reaction with the solvent gives the caution formed in the self-ionization of the solvent. It mentions solvents, such as hexane, acetone, acetonitrile, DMSO, and liquid sulfur dioxide, which do not self-ionize.

Abstract:

Microwave drilling is an advanced machining process in which electromagnetic energy converted into thermal energy with the help of a metallic concentrator is used to create the desired shape in the work material. High strength electric field developed around the tooltip ionizes the dielectric media around the tooltip and results in plasma formation. High-temperature plasma ablates the material just beneath the tool tip to create the desired hole in the workpiece. In the present research work, micro-hole drilling on thermoset and thermoplastic-based composites using microwave energy in the air and transformer oil has been investigated. The drilling characteristics have been investigated in terms of the heat-affected zone, and overcut; a comparison has been made in air and transformer oil. The study revealed that drilling in the presence of dielectric-like transformer oil reduces the defects like HAZ and overcut significantly. It was also observed that thermal damage was more in thermoset-based composites as compared to thermoplastic-based composites.

The primary requirement for transport of radiation through a material media is to have estimates for the absorption coefficients at the appropriate wavelengths. For many applications, the appropriate wavelengths are determined by the temperature of the material in question. In many other cases where the source of radiation is not characterized by the local temperature, one needs a versatile source of radiation continuously covering a wavelength interval appropriate for the problem at hand.

The ability of pulsed lasers to cause breakdown in gaseous media has been observed and studied nearly as long as lasers have been available.

Free electrons that are initially produced absorb laser radiation through a process known as inverse bremsstrahlung. After absorbing enough energy, the electrons collide with other species causing them to ionize and the process is repeated until a cascade ionization occurs. When
