It sometimes causes macroscopic or microscopic changes in the solid phase, especially modification of crystal type and size, specific surface changes or changing in chemical composition of solid phase, and it is commonly a slow process.
By exploring isomers with identical functional groups, the impact from changing in molecular composition on the observed different performance can be minimized.
The general distribution of these two kinds of sites was very similar (Figures 4a and 4b), with a lower number of sites identified to evolve under positive selection than changing in amino acid composition during the antiviral treatment.
The population, ever changing in numbers and composition through the interplay of births, deaths and migration, is the source of people with 'health conditions', or more precisely 'ill-health conditions': some with disabilities, and some with disease, thus generating the need for clinical health care.
The band ISIS makes its hard rock by a process of slow-cooking: what's inside the music is revealed only over the long haul, as textures and moods keep changing in the long compositions, from a deep bottom-end crunch to pretty melodic hazes.

Although the composition of the neighborhood has been changing in recent years, it still retains an Italian-American identity, and both young and old are involved.
The relative contributions of alcohol solubility and diffusivity to overall permeability are discussed, and changes in permeability, solubility, and diffusivity with changing composition in binary and ternary alcohol mixtures are described.
