The British Board of Film Classification (BBFC) operates exactly such a scheme in determining which imagery is suitable for a given age rating.
The US National Library of Medicine (NLM) offers this definition, based on the American Psychiatric Glossary: Developmental disabilities are "disorders in which there is a delay in development based on that expected for a given age level or stage of development.
For a given age of geopolymers, any quantity of replacement lowered linear shrinkage and about 10% mass of bauxite was enough to reduce efflorescence.
This allows an adequate prediction of the mass at which Li lines reappear in the spectra of brown dwarfs for a given age, or reversely an accurate determination of the age of a cluster.
Recent studies on North Pacific albacore (Thunnus alalunga) growth obtained age-length data from hard parts and fit the age-length data to a von Bertalanffy growth model, assuming each observation of length is a random sample for a given age.
Whether or not an app is appropriate for a given age group should be a problem that's best left to each platform's app review board, and a universal set of guidelines could only help.
When paired age length samples are collected from fishery data, estimation of the growth function parameters has typically assumed that each length observation is a random sample of fish for a given age (traditional method).
Furthermore, the algorithm incorporates a correction for slant-based sectional length measurements using the Pythagorean theorem and eliminates the need to predict heights for a given age by the use of a linear interpolation procedure.
During the years of socialism after the Second World War until 1989, early childhood education and care service provision became a state responsibility, and were highly centralized and uniform for a given age group.
For a given age-on-arrival and immigrant group, the cohort effect is Δδ c ≡ δ n,t + k,i − δ nti = C t + k − C t, where t is an earlier cohort than t + k.
