Modeling turkey growth with the relative growth rate.
Growth, development, and aging : GDA, 1999Six sigmoidal growth curves and two growth curves derived from a two-phase relative growth rate model were evaluated, using an experimental body-weight data from male and female turkeys of two genetic lines; a fast-growing (F) line and a randombred control (RBC) line from which the F line was developed. When their root mean square error was compared to

How to optimize lichen relative growth rates in growth cabinets
The Lichenologist, 2016AbstractIn order to improve growth chamber protocols for lichens, we tested the effect of 1) wet filter paper versus self-drained nets as a substratum for lichens, and 2) gradual versus abrupt transitions between dark and light periods. For Lobaria pulmonaria (L.) Hoffm.

Journal of Theoretical Biology, 2018
Growth curve models play an instrumental role to quantify the growth of biological processes and have immense practical applications across disciplines. In the modelling approach, the absolute growth rate and relative growth rate (RGR) are two most commonly used measures of growth rates.

Functional Ecology, 1989
Studies that measure maximum relative growth rates in a large number of plant species must often accept compromises between accuracy of estimation and the number of species that can be studied. In this paper is shown that one can obtain equivalent accuracy in estimating average maximum relative growth rate by using only aboveground tissues as when ...

Relative rates of growth of annoyance of impulsive and non-impulsive noises
The Journal of the Acoustical Society of America, 2002Twenty-nine people judged the relative annoyance of five variable level signals and 29 impulsive and non-impulsive fixed-level signals in an adaptive paired comparison study. Signals were presented for judgment as heard indoors in a facility capable of accurately reproducing the very low-frequency content of sonic booms.

Elasticity: The Relative Contribution of Demographic Parameters to Population Growth Rate
Ecology, 1986over plants grown without competition (P < .05). Plants suffering from both root and shoot competition were not significantly smaller than those suffering from root competition only, but they showed the greatest size variability. In plants competing both above and below ground, root competition accounted for the reduction in mean plant size, but shoot ...

Effect of selection for growth rate on relative growth in rabbits.
Journal of animal science, 2009The effect of selection for growth rate on relative growth of the rabbit body components was studied. Animals from the 18th generation of a line selected for growth rate were compared with a contemporary control group formed with offspring of embryos that were frozen at the seventh generation of selection of the same line.

Temperature Gradient Chamber for Relative Growth Rate Analysis of Yeast
Analytical Biochemistry, 1998Relative growth is often used as a phenotypic measure to distinguish mutant and wild-type yeast or bacterial strains. Differential growth as a function of temperature is a convenient and accurate means of analyzing differences between strains. Slight differences in the genotypes of two strains frequently result in differential growth of the two strains

Method for the determination of the relative spherulite growth rate
Journal of Crystal Growth, 1977Abstract A method of measurement of relative radial spherulite growth rate after completion of the crystallization process has been developed. Two basic characteristics of the crystallization process, spherulite nucleation and growth, are taken into account in the calculation of the theoretical form of boundary shape. The nucleation is represented by
