Great skill is necessary at every stage, but especially during faceting, because the angles of the facets must be exact in order to yield maximum brilliancy, and their sizes must be accurately regulated to preserve symmetry.
By adjusting the ratio of fluorine to titanium (RF), the structure of TiO2 products can be accurately regulated.
The hydraulic motor can be accurately regulated by controlling the pump displacement and fluid flows to change the pitch angle through the gear set.
Both spatial and temporal expression were accurately regulated in the ZRS3′del+LACZ/+ lines compared with ZRSwt+LACZ/+, initiating expression at the appropriate stage, ∼E10.5 (Fig. 3B,C), in both fore and hind limb and continuing to E11.5 (Fig. 3D,E).
Here, we extend this observation and show that the amounts of total ethanolamine phospholipids are accurately regulated and sustained at a remarkably constant level under conditions of complete or partial absence as well as upon excess of plasmalogens in vitro and in vivo.
This process needs to be accurately regulated and coordinated to ensure the generation of the proper number of terminally differentiated cells for each of the many neuronal cell types that compose the mature CNS (Iijima & Yokoyama, 2007; Valenciano et al, 2009; Vecino et al, 2004).
Iron homeostasis in normal cells is accurately balanced and tightly regulated by a coordinated functioning of several systems that are responsible for the uptake, intracellular storage, and removal of iron from cells [ 1]; in cancer cells, however, this balance is frequently and consistently compromised [ 2, 3].
As Watt emphasises, not all phenotypic plasticity is accurately portrayed as genetically controlled "switches" that regulate plastic responses.
To compensate the fluctuation of pumping efficiency, target poisoning and sputtering parameters, the flow rate of the reactive gas was rapidly and accurately regulated via a set of piezo valves and an optical emission monitor (OEM).
