The phrase "additional retardation" is correct and usable in written English.
It can be used in contexts related to physics, psychology, or any field discussing delays or slowdowns in processes or movements.
Example: "The experiment showed that the additional retardation of the object was due to increased friction on the surface."
Alternatives: "further delay" or "extra slowdown".
Twelve patients presented with additional mental retardation and/or autistic behaviour.
A multi-process retention model is proposed to account for potential additional sources of retardation for PFAS transport in source zones.
The growth rate and biomass yield of the mutant strain SAA026, carrying two copies of the Ll ldh gene, appeared not to be affected, whereas the strains carrying the Ll ldh gene also on a plasmid (SAW035 and SAW039) showed mild growth retardation (Additional file 1: Figure S1) and signs of a bleaching-like phenotype.
It is seen for the illustrative case of gamma energy 0.1 MeV and mass number 125 that there occurs an additional factor of 107 retardation with each higher multipole order.
Instead additional diagnoses of mental retardation, substance-related disorders or other Axis I disorders and the presence of any organic disease impairing psychiatric evaluation were considered exclusion criteria.
However, this same variant has subsequently been observed in an additional individual with mental retardation [ 64], but not in 320 controls with similar ethnic background.
We describe here a consanguineous Iranian pedigree in which PKD was diagnosed in four generations, but also included cases with additional abnormalities, including mental retardation.
When a sample of these same cells was switched to RM immediately after UV-irradiation, there was only a slight slowing of DNA synthesis, and the normal rate of synthesis was reestablished by 60 min. An additional mmrA mutation, or growth retardation by the addition of valine, blocked both this extra DNA synthesis in RM, and the inhibitory effect of RM on survival.
In cases wherein these additional retention processes are significant, retardation of PFAS in source areas would likely be greater than what is typically estimated based on the standard assumption of solid-phase adsorption as the sole retention mechanism.
When a sample of these cells was incubated in RM after UV-irradiation, there was only a slight slowing of DNA synthesis, and the normal rate of synthesis was re-established by 60 min. An additional mmrA mutation, or growth retardation by valine, blocked both this extra DNA synthesis in RM and the inhibitory effect of RM on survival.
