A Microeconomic Mechanism for Economic Growth
Journal of Political Economy, 1991This paper constructs a dynamic general equilibrium model in which economic growth is explained by the evolution of the division of labor. The relationships among the accumulation of human capital, the evolution of the division of labor, endogenous comparative advantage, trade dependence, the market structure, and economic growth are investigated.

Growth Mechanisms and Growth Kinetics of Filamentous Microorganisms
Critical Reviews in Biotechnology, 1991Filamentous microorganisms are of major biotechnological importance, being responsible for production of the majority of secondary metabolites, particularly antibiotics. Two main groups are involved, filamentous fungi and filamentous actinomycetes, particularly the streptomycetes.

Nature, 1962
FUNCTIONAL activity of the hair follicle is known to be a cyclical phenomenon in many species1,2, involving periods of active growth and periods of apparent inactivity. The mechanism controlling this cycle is cutaneous, since hair-growth occurs in vitro3–5. The nature of this control mechanism is unknown.

A mechanism of microbial cell growth
Biotechnology and Bioengineering, 1972AbstractPresently empirical expressions, especially the Monod equation, are used to quantitatively relate microbial growth rate to limiting substrate concentration in the solution. In this paper microbial growth is postulated to occur by a mechanism involving a mass transfer or assimilation process.

Abstract The direction of DNA chain growth in thymine-depleted bacteria was determined by comparing the rate of release of radioactive label by Escherichia coli exonuclease I from pulse-labeled DNA chains to that of uniformly labeled DNA of the same size.

Growth Mechanisms of “Katie's Floeberg”
Arctic and Alpine Research, 1978The growth mechanism of the grounded ice feature on Hanna's Shoal, located at approximately 162 deg W, 72 deg N in the Chukchi Sea, has been analyzed using Landsat I and II satellite imagery. The primary mechanism of growth was deduced to be the formation of large wedges of ice against the upstream edge of the feature. These wedges of piled ice form in

Regulation Mechanisms of Hair Growth
2015The dorsal resting hair of C3H mice at various ages was shaved, thus activating the hair into the anagen stage. New hair growth after shaving was not uniform in the various age groups. Furthermore, an increasing delay in hair regrowth was observed as the mice became older (20, 66, 188, and 312 days).

Mechanisms of genesis and growth of calculi
The American Journal of Medicine, 1968Abstract The purpose of this discussion is to examine some of the stone-forming mechanisms at the basic level. An attempt is made to consider three persistent root questions: (1) What is the physicochemical mechanism by which stone material is synthesized or put together?

Mechanisms of reduced and compensatory growth
Domestic Animal Endocrinology, 2000Growth is an integrated process, resulting from the response of cells dependent on the endocrine status and nutrient availability. During feed restriction, the production and secretion of growth hormone (GH) by the pituitary gland are enhanced, but the number of GH receptors decreases.
