Also, contradictory results have been reported that acidic conditions are not required for initiation of solventogenesis (George and Chen 1983).
Viral entry is required for initiation, spread, and maintenance of infection, and thus is a promising target for antiviral therapy.
This apparatus was designed for controlling confining stresses and determining critical hydraulic gradients and critical velocities required for initiation of internal erosion.
Curdlan production was not seen during the cell growth phase and nutrient limitation was required for initiation of curdlan biosynthesis (Lee at al.1997& Jung et al.2001).2001
During both types of transesterification reactions, the minimum time required for initiation of biodiesel yield was 25 min, while below this no prominent phase separation was observed.
This suggests that Ca2+ influx through presynaptic P/Q-type Ca2+ channels with consequent release of glutamate from cortical cell synapses and activation of NMDA-R is required for initiation and propagation of the CSD [62].
Our analysis reveals that a small obstacle curvature in a direction perpendicular to the string axis leads to a considerable reduction in the critical amplitudes required for initiation of whirling motions.
Unlike initiation from the cap structure, the subset of proteins required for initiation from a eukaryotic IRES has yet to be determined.
Deregulated Cln expression inhibits the assembly of pre-replicative complexes (pre-RCs) required for initiation of DNA replication at replication origins [68].
Sulfur metabolism is required for initiation of cell division, but whether or not it can actively promote cell division remains unknown.
Tumor cells move through successive series of coordinated and integrated stages, with formation of protrusive membranous structures including filopodia, invadopodia and lamellipodia required for initiation and maintenance of invasion and migration [2], [3], [4], [5].
