Relaxation time — is a general concept in physics for the characteristic time in which a system changes to an equilibrium condition from a non equilibrium condition. It can measure the time dependent response of a system to well defined external stimuli.… … Wikipedia
relaxation phenomenon — ▪ physics and chemistry Introduction in physics and chemistry, an effect related to the delay between the application of an external stress to a system that is, to an aggregation of matter and its response. It may occur in nuclear, atomic,… … Universalium
Relaxation (physics) — In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium. Each relaxation process can be characterized by a relaxation time τ. The simplest theoretical description of relaxation as function of time t is … Wikipedia
relaxation — 1. Loosening, lengthening, or lessening of tension in a muscle. 2. In nuclear magnetic resonance, r. is the decay in magnetization of protons after the direction of the surrounding magnetic field is changed; the different rates of r. for… … Medical dictionary
Transverse relaxation optimized spectroscopy — (TROSY) is an experiment in protein NMR spectroscopy that allows studies of large molecules or complexes.The application of NMR to large molecules is normally limited by the fact that the line widths generally increase with molecular mass. Larger … Wikipedia
Dielectric relaxation as a chemical rate process — Dielectric relaxation was interpreted as a chemical rate process by Walter Kauzmann. According to Kauzmann, relaxation rates may be arranged in two or more distinct groups: Depending on how rapidly they change with temperature. In one group, we… … Wikipedia
Mindbody relaxation — The goal of mindbody relaxation is to relax both the body and mind. The basic idea is that it s easier to relax your mind if you first relax your body.[1] There are a variety of mindbody relaxation techniques including yoga and meditation.[2]… … Wikipedia
Dielectric relaxation — is the momentary delay (or lag) in the dielectric constant of a material. This is usually caused by the delay in molecular polarization with respect to a changing electric field in a dielectric medium (e.g. inside capacitors or between two large… … Wikipedia
Spin-lattice relaxation time — Spin lattice relaxation time, known as T1, is a time constant in Nuclear Magnetic Resonance and Magnetic Resonance Imaging. It is named in contrast to T2, the spin spin relaxation time.T1 characterizes the rate at which the longitudinal Mz… … Wikipedia
Heart rate — is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). Heart rate can vary as the body s need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep. The measurement of heart… … Wikipedia
Reaction rate constant — In chemical kinetics a reaction rate constant k or λ quantifies the speed of a chemical reaction.[1] For a chemical reaction where substance A and B are reacting to produce C, the reaction rate has the form: Reaction: A + B → C k(T) is the… … Wikipedia
