Formulation And Stoichiometry

Specifically written to meet the needs of the cosmetic chemist and engineer, this reference outlines the latest technologies and issues pertinent to the development novel skin care products including advances in formulation and development, raw materials and active ingredients, compound testing, and clinical assessment.

This book gives a unifying framework for estimating the abundance of open populations: populations subject to births, deaths and movement, given imperfect measurements or samples of the populations. The focus is primarily on populations of vertebrates for which dynamics are typically modelled within the framework of an annual cycle, and for which stochastic variability in the demographic processes is usually modest. Discrete-time models are developed in which animals can be assigned to discrete states such as age class, gender, maturity, population (within a metapopulation), or species (for multi-species models).
