The volume or weight loss is initially curvilinear. The wear rate per unit sliding distance in the transient wear regime decreases until it has reached a constant value in the steady-state wear regime. Hence the standard wear coefficient value obtained from a volume loss versus distance curve is a function of the sliding distance. [3]
C, which are used to calculate Fm, the "fraction modern". This is defined as the ratio between the 14 C / 12 C ratio in the sample and the 14 C / 12 C ratio in modern carbon, which is in turn defined as the 14 C / 12 C ratio that would have been measured in 1950 had there been no fossil fuel effect.

The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.
Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight.
Members complete annual questionnaires about their current weight, diet and exercise habits, and behavioral strategies for weight loss maintenance. [1] The National Weight Control Registry is coordinated through the Miriam Hospital's "Weight Control and Diabetes Research Center" in Providence, Rhode Island. It was founded and is currently ...
Several formulas exist, having different utility for different purposes. For example, the Boer formula is method of choice for LBM estimation to calculate the dose given in contrast CT in obese individuals with BMI between 35 and 40. [3] A nomogram based on height, weight and arm circumference may be used. [4]
The HP Voyager series calculator are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional ...
