In this paper, the effect of a new low-VOC coalescent on film formation assessed through AFM, dirt pick-up resistance of semi-gloss paints, and leaching of flat paints is presented.
These galls, therefore, may be considered coalescent galls, specially induced by distinct species.
Efficiency tests were conducted by adding 90 g of latex to a container, adding the appropriate level of coalescent to be tested, and adjusting with water to 100 g total.

The best methods for inferring the effects of selection and gene flow on new species formation, and distinguishing those effects from other processes (such as mutation), are based on the concept of the coalescent: the pattern of merging or coalescence of alleles backward in time from the present to a common ancestral allele at some time in the past (Kingman, 1982; Hudson, 1990).

The starting point was the coalescent-free PUD resin SAPICI Bluepur 2937; the challenge was to identify - for the formulation of the final product that is used by the applicators - a sustainable and non-glycolic coalescent originated from biological and renewable sources able to combine environmental aspects with high technical properties, characteristics and durability for the final paint.

Comparing likelihood and Bayesian coalescent estimation of population parameters.
In genetics, coalescent theory is a retrospective of population genetics that traces all genes in a sample from a population to a single ancestral copy shared by all the members of the population.

We use analytical approaches based on coalescent theory that allow the co-estimation of divergence times among populations and the migration rates among them (the isolation-migration model; Hey & Nielsen 2004).
