- An isothermal process means that the temperature of the gas does not change during the expansion or compression. An isobaric process means that the pressure of the gas does not change while in an isovolumetric (isochroic) process the volume remains constant.

Isometric exercise An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term isometric combines the Greek words Isos (equal) and metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied.

Glossary of Geophysical Terms (A,B,C) Comprised of a real and imaginary part. Complex resistivity (CR). A geophysical effect, also the basis of the CR method, in which polarization within the medium results in the voltage and applied current being out of phase – that is, their ratio is complex. Also known as spectral IP.

Mathematical Relationships in Science Inverse-square law. In physics, an inverse-square law is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity.

Fifteenth Amendment to the United States Constitution In the twentieth century, the Court began to interpret the amendment more broadly, striking down grandfather clauses in Guinn v. United States (1915) and dismantling the white primary system in the Texas primary cases (1927–1953).

- with F evol as the volumetric elastic deformation (a diagonal tensor) and the isochoric elastic deformation gradient. Isochoric deformation means that the volume ratio is kept constant during deformation, so the isochoric elastic deformation is computed by scaling it by the elastic volume ratio.The elastic volume ratio is defined by.t turns out to be convenient for some classes of hyperelastic materials to split the strain energy density into volumetric (also called dilatational) and isochoric (also called distortional or volume-preserving) contributions.

The Isochoric Process Definition: An isochoric process is a thermodynamic process in which the volume remains constant. Since the volume is constant, the system does no work and W = 0. This is perhaps the easiest of the thermodynamic variables to control, since it can be obtained by placing the system in a sealed container which neither expands nor contracts.

Confined or artesian groundwater The potentiometric surface is an imaginary surface above the aquifer, to which water from an artesian aquifer would rise in a pipe. The term potentiometric surface means head- or potential-indicating surface and is preferable to the term piezometric surface, which is found in some literature.

Rotation around a fixed axis Physical quantities: Mass moment of inertia. In classical mechanics, moment of inertia, also called mass moment of inertia, rotational inertia, or the angular mass, (SI units kg m2), is a measures of an object’s resistance to changes to its rotation.

What Is Isobaric Process? Adiabatic process - a process with no heat transfer into or out of the system. Isochoric process - a process with no change in volume, in which case the system does no work. Isobaric process - a process with no change in pressure. Isothermal process - a process with no change in temperature.

isoelectric an electrophoretic method for separating proteins in gels which depends on the fact that the net charge on the protein varies with the pH of the surrounding medium. At the isoelectric point the protein has no net charge and will not therefore migrate further in an electric field. The polyacrylamide gel is cast in a narrow tube that provides a pH gradient from top to bottom.

- The driving-point admittance of the body of the instrument, characterizes linear-interactions between the string and the body in both directions: meaning energy transferred from both string to body and body to string. (3) where for a given frequency , the ratio between the Fourier Transform of the velocity and force is known. A physical explanation of the driving-point admittance is to view the admittance as a measure of how readily force exerted at the contact point at a certain frequency results in motion at that same frequency [23].

Effective Isotropic Radiated Power (EIRP) EIRP is Effective Isotropic Radiated Power, also called the Equivalent Isotropic Radiated Power. In antenna measurements, the measured radiated power in a single direction (that is, for a fixed and ) is known as the EIRP. Typically, for an antenna radiation pattern measurement, if a single value of EIRP is given, this will be the maximum value of the EIRP over all measured angles.

Infinitesimal strain theory In continuum mechanics, the infinitesimal strain theory is a mathematical approach to the description of the deformation of a solid body in which the displacements of the material particles are assumed to be much smaller (indeed, infinitesimally smaller) than any relevant dimension of the body; so that its geometry and the constitutive properties of ...

- The rotational constant of the ground vibrational state B ′′ and centrifugal distortion constant, D ′′ can be found by least-squares fitting this difference as a function of J. The constant B ′′ is used to determine the internuclear distance in the ground state as in pure rotational spectroscopy.itric oxide, NO, is a special case as the molecule is paramagnetic, with one unpaired electron. Coupling of the electron spin angular momentum with the molecular vibration causes lambda-doubling with calculated harmonic frequencies of 1904.03 and 1903.68 cm −1. Rotational levels are also split.
