While this dismal description may strike us as mostly true at the level of the industry, at the firm level there are many barriers we need to understand that would allow the individual firm to grow faster. Thus the challenge is not necessarily that growth decreases over time universally, but is the issue of what firms can do to overcome growth barriers faster than their competitors.

Fig. 3. Curve ihustrating the activation energy (barrier) to nucleate a crystalline phase. The critical number of atoms needed to surmount the activation barrier of energy AG is n and takes time equal to the iacubation time. One atom beyond n and the crystahite is ia the growth regime.

A skin woundprotectant is a nonirritating antimicrobial-containing preparation appHed to small cleansed wounds it provides a protective physical barrier and a chemical (antimicrobial) barrier that neither delays healing nor favors the growth of microorganisms. 

Here, D is the diffusion constant for heat or material and the kinematic viscosity of the liquid. A consequence of the existence of such a diffusive surface barrier is that the diffusion length = D/F is to be replaced by in all formulas, as soon as growth rate V the more important become the hydrodynamic convection effects.
