However, reducing the gas-to-liquid ratio to enhance gas phase methane purity introduced gas-phase controlled mass transfer which constrained removal efficiency.
Viewed together, the lactation duration allometries raises the possibility that both the claim that energy transfer is constrained by the structure of the internal resource distribution networks and the claim that natural selection has maximized the rate of resource transfer may be wrong.
The departure of allometries for total development time and its individual components from the predictions of the MTE has serious implications for at least one of two key claims of the MTE that energy transfer is constrained by the structure of the internal resource distribution networks, and that natural selection has maximized the rate of resource transfer within the body.
Of course, energy can be provided by transcutaneous transfer, using electro-magnetic coupling with an external source; but with the exception of cochlear implants, where a simple and miniaturized device can be used, transcutaneous energy transfer is very constraining for the patient, who accepts this only in specific cases such as artificial hearts [5], where immediate survival is at stake.
Similarly, high-resolution neuroanatomy makes predictions about information transfer and transformation, constraining models of neural processing.
If alanine and pyruvate transfer are also constrained, the model predicts an aspartate/malate shuttle.
In this study system, pollen transfer is probably constrained by pollinator limitation in large patches and by mate limitation in small patches, decreasing seed production by 34% on average [ 35].
Gene transfer may be constrained for the same reasons as in the case of mitochondria: if compartmentalization of function (and thus the presence of the symbiont) is important, the major constraining factor for transfer is the ease of importability of proteins (targeting, import and assembly) into the compartment [ 1, 13].
This dependency can promote the persistence of a phylogenetic signal in the face of significant gene transfer when the transfer process reinforces host preferences imposed through constraining core functions.
The iSS884 model was used to evaluate the metabolism of xylose by constraining it to experimental oxygen transfer rates.
