Estimating growth parameters from growth rate data
Oecologia, 1975The time interval over which growth rates are measured modifies the observed growth rates in non-linear growth curves. Growth rates obtained from a sigmoid curve such as the logistic growth equation may appear as if they were derived from the non-sigmoid von Bertalanffy growth equation when the small stage is not represented in the hypothetical growth ...

Age-Related Reference Ranges for Growth Parameters
Methods of Information in Medicine, 1995Abstract:We propose an approach to the computation of age-related reference ranges which guarantees that the proportion of sampled data points covered by the reference band has an arbitrarily specified value. Unlike other approaches in the literature, this method does not have to rely on parametric distributional assumptions.

Estimating Parameters of Growth Curves of Bulls
Journal of Animal Science, 1989Parameters were estimated for nonlinear growth curves for bulls of five straightbred and 20 crossbred breed-types produced in two generations of a diallel. The primary intent of this study was to use the estimates obtained for mature size and maturing rate to define male growth in manner that would be appropriate for use in the Texas Agricultural ...

Parameters for crystal growth of ribosomal subunits
Journal of Cellular Biochemistry, 1982AbstractA systematic analysis of the parameters that control the crystal growth of the large subunit of ribosomes from B stearothermophilus has been carried out. Several parameters have been identified and classified according to their significance. It was found that only biologically active particles can crystallize and that the critical period for ...

Measuring parameters of growth
1995Abstract This chapter deals with the various parameters of growth and how they can be measured. A tissue can grow by: (i) increasing the number of cells; (ii) increasing the size of the cells; or (iii) increasing the amount of intercellular substance. Since the intercellular substance of a tissue is usually a secreted product of the cell,

Parameter heterogeneity in growth regressions
Economics Letters, 2008Abstract This paper explores the appropriateness of pooling many diverse countries together in growth regressions. It is shown that estimates are sensitive to small changes in the sample, and separating OECD and non-OECD countries can result in drastic differences.

Genetic parameters of growth curve parameters in male and female chickens
British Poultry Science, 19991. Individual growth curves of 7143 chickens selected for the form of the growth curve were fitted using the Laird form of the Gompertz function, BW4=BW0xe(L/K)(1-e-Kt) where BWt is the body weight at age t, BW0 the estimated hatching weight, L the initial specific growth rate and K the maturation rate. 2. Line and sex effects were significant for each

Parameters influencing unwanted growth during epitaxial growth of SiGe
2016 27th Annual SEMI Advanced Semiconductor Manufacturing Conference (ASMC), 2016In the advanced nodes of 28nm and below, small defects too can have a significant impact on the final yield results of wafers. As the technology node advances it has become increasingly challenging to control the extent of defects while also ensuring that the desired processing parameters are in place. In this paper we evaluate the influence of various

The estimation of growth yield and maintenance parameters for photoautotrophic growth
Biotechnology and Bioengineering, 1984AbstractMethods are presented for examining the consistency of experimental data for microbial growth where light energy is converted to chemical energy through photosynthesis. True growth yield and maintenance parameters are estimated for several sets of available experimental data.

Practical Methods for Determining Phage Growth Parameters
2009Bacteriophage growth may be differentiated into sequential steps: (i) phage collision with an adsorption-susceptible bacterium, (ii) virion attachment, (iii) virion nucleic acid uptake, (iv) an eclipse period during which infections synthesize phage proteins and nucleic acid, (v) a "post-eclipse" period during which virions mature, (vi) a virion ...
