kinetics

 [kĭ-net´iks; ki-net´iks]
the scientific study of the turnover, or rate of change, of a specific factor in the body, commonly expressed as units of amount per unit time.
chemical kinetics the scientific study of the rates and mechanisms of chemical reactions.
urea kinetics the movement of urea in the body and its excretion through the kidneys or dialysis apparatus; see also urea clearance.

ki·net·ics

(ki-net'iks),
The study of motion, acceleration, or rate of change.

Etymology: Gk, kinesis + L, icus, like
1 the study of the forces that produce, arrest, or modify the motions of the body. Newton's first and third laws of motion are especially applicable to kinetics. Newton's first law states that bodies at rest stay at rest and bodies in motion keep moving unless they are acted on by an unbalancing force. Newton's third law states that every action force has a reaction force that is equal in magnitude but opposite in direction. These two laws apply to the forces produced by muscles that act on joints. The reaction forces of the muscles contribute to equilibrium and the motion of the body. Compare kinematics.
2 the study of the rate of chemical and biochemical reactions as in chemical kinetics and enzyme kinetics. It may also refer to the fate of pharmaceuticals upon administration to an organism in terms of absorption, distribution, metabolism and excretion (pharmacokinetics).

ki·net·ics

(ki-net'iks)
The study of motion, acceleration, or rate of change.

kinetics

the study (and measurement) of forces and moments (torques). linear kinetics the study of forces but not torques or moments. angular kinetics the study of torques or moments but not linear forces.

kinetics,

n 1. area of study that examines the effects of outside influences on the movement of material bodies.
2. the study of the interrelationships that exist between body parts and how those connections influence movement.

ki·net·ics

(ki-net'iks)
The study of motion, acceleration, or rate of change.

kinetics

(kənet´iks),
n the study of the forces that produce, arrest, or modify the motions of the body. Kinetics is the application of Newton's first and third laws of inertia to body dynamics. The reaction forces of the muscles contribute to the equilibrium and motion of the body.

kinetics

the scientific study of the turnover, or rate of change, of a specific factor in, or position of the body, commonly expressed as units of amount per unit time.

chemical kinetics
the scientific study of the rates and mechanisms of chemical reactions.
locomotion kinetics
study of the rates and mechanisms of the movement or progression of animals.

The aim of this study is to estimate patient nutritional parameter nPNA individually by the on-line DIAMON prototype, by formal urea kinetic modelling, and by modified direct dialysis quantification.
Our sample size was limited, as urea kinetics have only been routinely performed at our institution since June 2000.
The mean value of the patient characteristics, the urea kinetics, and the prehemodialysis serum concentrations of urea, creatinine, total p-cresol, free p-cresol, and albumin with their minimum-maximum ranges are listed in Table 1.
