Secondary module reduced

Terms such as stolon, primary and secondary stem, and branch, have often been used without careful attention to the role of the apical cell in formation of each of these features. Consequently, a primary stem in one taxon may equate to a stolon in a second, and a branch in a third, while a secondary stem may be the continuation of the primary stan but with a different orientation, a new primary module, or a secondary module (a branch ). This lack of clarity reduces the information content of these terms and makes structural comparisons between taxa difficult or meaningless, especially for determination of homology in cladistic analysis. [Pg.290]

Design arrangements for reduced-temperature secondary systems (sometimes referred to as injection circuits) include fixed provisions for minimum dilution rates. Conventional system-balancing devices with three-port automatic modulating valves to regulate mixed water temperatures and, hence, heat output are used. Automatic safety controls must prevent excessive temperatures occurring in the coil circuits, as floor fabrics or finishes could be damaged very rapidly. [Pg.408]

The outline of this paper is as follows. First, a theoretical model of unsteady motions in a combustion chamber with feedback control is constructed. The formulation is based on a generalized wave equation which accommodates all influences of acoustic wave motions and combustion responses. Control actions are achieved by injecting secondary fuel into the chamber, with its instantaneous mass flow rate determined by a robust controller. Physically, the reaction of the injected fuel with the primary combustion flow produces a modulated distribution of external forcing to the oscillatory flowfield, and it can be modeled conveniently by an assembly of point actuators. After a procedure equivalent to the Galerkin method, the governing wave equation reduces to a system of ordinary differential equations with time-delayed inputs for the amplitude of each acoustic mode, serving as the basis for the controller design. [Pg.357]

As in the liver, drugs that undergo renal P-gp transport are susceptible to interactions resulting from modulation of P-gp- Inhibition of renal P-gp may lead to the development of unexpected toxicities or improved clinical efficacy secondary to increased drug exposure. Clarithromycin was found to increase the bioavailability of and reduce the renal clearance of digoxin in a group of healthy volunteers, resulting... [Pg.241]

If a second redox protein is present under the conditions represented by Eq. 3 or 5, secondary protein-protein ET reactions can occur, again subject to thermodynamic and kinetic constraints. In this situation, however, the constraints can be modulated by having the higher potential (under oxidizing conditions) or lower potential (under reducing conditions) protein present in stoichiometric excess, thereby favoring removal of electrons from (or entry of electrons into) the appropriate protein in the initial reaction with exogenous flavin. [Pg.2583]

The mechanisms responsible for the contractile responses to AmB have not been identified. Theoretically, the drug can act either directly on the vascular smooth muscle or through release of secondary mediators. A large number of studies have examined putative indirect mechanisms of action. Those studies have revealed that neither renal denervation nor angiotensin II receptor blockade prevent the renal vasoconstriction or the reduction in GFR [87, 88]. Although Cutaia et al [89] demonstrated a toxic effect of AmB on endothelial cells, endothelin does not appear to be involved in the acute responses to AmB [88, 90] and reduced nitric oxide synthesis, consequent to endothelial injury is not involved in modulation of AmB-induced renal vasoconstriction [88]. [Pg.330]
