Replacement Rates for Human Tissue from Atmospheric Radiocarbon

Science, 1964
Carbon-14, derived from the testing of thermonuclear weapons in the atmosphere of the Northern Hemisphere during 1961-62, has been found in human tissues including the brain in amounts which reflect the atmospheric concentration of carbon-14 as of several months earlier.

Optimum replacement rates in animal breeding

Animal Science, 1974
SUMMARYThe expected annual selection response is a function of selection intensity (i), generation interval (t) and precision (p) of breeding value estimation. These three parameters may, under certain conditions, be reduced to functions of one variable, y, the mean age of breeding animals at culling, which is a simple function of the annual ...

Research on factors of pension replacement rate

The 2nd International Conference on Information Science and Engineering, 2010
Based on the definition of average pension replacement rate and previous researches, the paper divided five systematic modules that can affect pension replacement rate. Then authors analyzed the factors and concrete index of the five modules respectively, and discussed the real factors of pension replacement rate by using mathematical analysis, and ...

Retirement Replacement Rates and Saving Behavior

SSRN Electronic Journal, 2014
We study whether the retirement replacement rate influences households' saving behavior by using the RAND Health and Retirement Study data file. We estimate quantile regressions with the ratio of wealth to permanent income as dependent variable, and age dummies and the retirement replacement rate as main independent variables. Our paper is the first to

Replacement when constant failure rate precedes wearout

Naval Research Logistics Quarterly, 1961
AbstractAssume a component has a constant failure rate during the first τ unit of time following installation. After that, wearout sets in so that failure rate begins to increase sharply. Assume further that replacement is made at the time of component failure or at τ units of time following installation, whichever occurs first. Under these assumptions,
