Nelson process

The simulations also revealed that flapping motions of one of the loops of the avidin monomer play a crucial role in the mechanism of the unbinding of biotin. The fluctuation time for this loop as well as the relaxation time for many of the processes in proteins can be on the order of microseconds and longer (Eaton et al., 1997). The loop has enough time to fluctuate into an open state on experimental time scales (1 ms), but the fluctuation time is too long for this event to take place on the nanosecond time scale of simulations. To facilitate the exit of biotin from its binding pocket, the conformation of this loop was altered (Izrailev et al., 1997) using the interactive molecular dynamics features of MDScope (Nelson et al., 1995 Nelson et al., 1996 Humphrey et al., 1996). [Pg.44]

The cytoskeleton is involved in the maintenance of cell shape and cytoplasmic processes (e.g., microvilli). In polarized epithelial cells, distinct cyto-cortical cytoskeletal complexes are associated with the apical and basal-lateral domains of the plasma membrane (Rodriguez-Boulan and Nelson, 1989 Mays et al., 1994). [Pg.35]

The range of processes that must be considered in the cycle of metals is described in Fig. 15-10 (Nelson et al., 1977). Both the complexity of metal cycle analysis in a real system and the importance of speciation are well-stated by Andreae (1979) in his overview of the arsenic cycle in seawater ... [Pg.398]

The Wagner-Nelson method of calculation does not require a model assumption concerning the absorption process. It does require the assumption that (a) the body behaves as a single homogeneous compartment and (b) drug elimination obeys first-order kinetics. The working equations for this calculation are developed next. [Pg.91]

By sending legitimate chemists such as Ramsay and Baskerville samples to test, Hunter was following in the footsteps of Emmens, who in 1897 had sent samples and instructions for repeating his process to Sir William Crookes, who was unable to reproduce Emmens s results. In 1898, Emmens launched his Argentaurum Company, which advertised that for each ounce of silver submitted by investors it would return 3/5 of an ounce of gold. Emmens s efforts to start the company failed, though, when his patent application for the process was turned down (Nelson 2000, 58). [Pg.227]

Nelson But we don t see what you do the Ca2+ channel opening and then a local blast of Ca2+ turning on the RyRs in a few milliseconds. In smooth muscle this process is slower and is quite different. This may reflect a fundamentally different arrangement of the Ca2+ channels with respect to the RyR and this may be common in smooth muscle. [Pg.24]

Nelson I think it affects the bursting. There is another clock here. If we add iberiotoxin to bladder strips, the amplitudes and durations of the phasic contractions increase. We also observe a slowing of the phasic contraction frequency. This suggests that it is some sort of slow Ca2+ dependent process that causes longer periods between contractions. The net effect of iberiotoxin is a large increase in force amplitude and duration rise, the frequency goes down. [Pg.206]

This correlation is an extension of the Lockhart-Martinelli correlation. The earlier correlation is limited to low pressures and systems in which no change of phase occurs. Although Lockhart and Martinelli provided for four flow regimes, it is unusual in industrial processes for either phase to be in laminar flow. The Martinelli-Nelson (1948) correlation is specifically for forced circulation boiling of water in which it is assumed that both phases are in turbulent flow. [Pg.256]
