Poynting Theorem

The generalized Poynting theorem is applied to the equilibrium system of particles, both inside and outside the system. The particles are bound to each other by means of the electromagnetic and gravitational fields, acceleration field and pressure field. As a result, the correlation is found between the acceleration field coefficient, the pressure field coefficient, the gravitational constant and the vacuum permittivity. This correlation also depends on the ratio of the charge density to the mass density of the particles inside the sphere. Due to the correlation between the given field coefficients the 4/3 problem is solved and the expression for the relativistic energy of the system is refined.

Gravitational Equilibrium

The motion equations of matter in a gravitational field, acceleration field, pressure field, and other fields are considered based on the field theory. This enables us to derive simple formulas in the framework of the gravitational equilibrium model, which allow us to estimate the physical parameters of cosmic bodies. The acceleration field coefficient, η, and the pressure field coefficient, σ, are a function of the state of matter, and their sum is close in magnitude to the gravitational constant, G. In the presented model the dependence is found of the internal temperature and pressure on the current radius. The central temperatures and pressures are calculated for the Earth and the Sun, for a typical neutron star and a white dwarf. The heat flux and the thermal conductivity coefficient of these objects’ matter are found, and the formula for estimating the entropy is provided. All the quantities are compared with the calculation results in different models of cosmic bodies. The discovered good agreement with these data proves the effectiveness and universality of the proposed model for estimating the parameters of planets and stars and for more precise calculation of physical quantities.

Questions And Answers

Abstract Controversy attends use of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) in defining injured workers’ permanent partial disability benefits: States desire an efficient, nonsubjective way to determine benefits for nonscheduled injuries and are using the AMA Guides to define the extent of disability. Organized labor is concerned that use of the AMA Guides, particularly with modifications, does not yield a fair analysis of an injured worker's disability. From its first issue, The Guides Newsletter emphatically emphasized and clearly stated that impairment percentages derived according to AMA Guides criteria should not be used to make direct financial awards or direct estimates of disability. The insurance industry and organized labor differ about the use of the AMA Guides in defining permanent partial disability (PPD). Insurers support use of the AMA Guides because they seek a uniform system that minimizes subjectivity in determining benefits. Organized labor is particularly concerned about the lack of fairness of directly equating impairment and disability, and if the rating plays a role in defining disability, additional issues also must be considered. More states are likely to use the AMA Guides with incorporation of additional features such as an index to PPD.

Having developed a framework for subsuming gravity into relativity, we examine how gravity behaves as a function of the source mass (Earth, Sun, etc.) and distance from that sourcemass.We develop Newton’s inverse‐square law of gravity, and we examine the consequences in terms of acceleration fields, potentials, escape velocities, and surface gravity. Chapter 17 will build on these ideas to show how orbits are used to probe gravity throughout the universe.We also develop a tool for exposing variations in the acceleration field: the tidal acceleration field in any region is defined as the acceleration field in that region minus the average acceleration. This enables us to restate Newton’s lawof gravity as: the acceleration arrows surrounding any point show a net convergence that is proportional to the density of mass at that point. Chapter 18 will use this to develop a frame‐independent law of gravity.
