System driven

It is possible that the driven equipment to which the motor is coupled has a higher vibration level than the motor, resulting in quantum imbalance and more vibrations than when the motor was tested. All attempts must be made, to bring the vibration level of the drive and the driven system within the limits as prescribed in Table 11.3. [Pg.240]

The flow profiles of electrodriven and pressure driven separations are illustrated in Figure 9.2. Electroosmotic flow, since it originates near the capillary walls, is characterized by a flat flow profile. A laminar profile is observed in pressure-driven systems. In pressure-driven flow systems, the highest velocities are reached in the center of the flow channels, while the lowest velocities are attained near the column walls. Since a zone of analyte-distributing events across the flow conduit has different velocities across a laminar profile, band broadening results as the analyte zone is transferred through the conduit. The flat electroosmotic flow profile created in electrodriven separations is a principal advantage of capillary electrophoretic techniques and results in extremely efficient separations. [Pg.199]

Although many terms are generally obvious to engineers, a few selected terms should be reviewed when referring to motor-driven systems. [Pg.615]

Some mechanically driven systems include heated vessels or spraying of the water to enhance the natural evaporation rate. In heating, the energy needed to evaporate the water is equal to that needed to bring the water to the temperature of vaporization plus that energy required for the evaporation, where for constant volume this is... [Pg.1357]

Examples of entropically driven systems will be those employing chirally active stationary phases. [Pg.33]

Deprived of their substrate in severe or prolonged hypoxia, some ATPase-driven systems, including ion pumps, may become impaired. Further, with the decrease in the availability of O2 as its terminal electron acceptor, the mitochondrial transport chain becomes increasingly unable to accept reducing equivalents from cellular metabolic processes. Hence the intracellular pH falls, subjecting the cell as a whole to a reductive stress and favouring those enzyme systems with acid pH optima. [Pg.100]

A typical trajectory has nonzero values of both P and Q. It is part of neither the NHIM itself nor the NHIM s stable or unstable manifolds. As illustrated in Fig. la, these typical trajectories fall into four distinct classes. Some trajectories cross the barrier from the reactant side q < 0 to the product side q > 0 (reactive) or from the product side to the reactant side (backward reactive). Other trajectories approach the barrier from either the reactant or the product side but do not cross it. They return on the side from which they approached (nonreactive trajectories). The boundaries or separatrices between regions of reactive and nonreactive trajectories in phase space are formed by the stable and unstable manifolds of the NHIM. Thus once these manifolds are known, one can predict the fate of a trajectory that approaches the barrier with certainty, without having to follow the trajectory until it leaves the barrier region again. This predictive value of the invariant manifolds constitutes the power of the geometric approach to TST, and when we are discussing driven systems, we mainly strive to construct time-dependent analogues of these manifolds. [Pg.199]

The exact meaning of this condition depends on the details of the external driving and has to be specified on a case-by-case basis. The notion of the TS trajectory is thereby given enough flexibility to offer a guiding concept for the study of different types of driven systems. [Pg.202]

We have outlined how the conceptual tools provided by geometric TST can be generalized to deterministically or stochastically driven systems. The center-piece of the construction is the TS trajectory, which plays the role of the saddle point in the autonomous setting. It carries invariant manifolds and a TST dividing surface, which thus become time-dependent themselves. Nevertheless, their functions remain the same as in autonomous TST there is a TST dividing surface that is locally free of recrossings and thus satisfies the fundamental requirement of TST. In addition, invariant manifolds separate reactive from nonreactive trajectories, and their knowledge enables one to predict the fate of a trajectory a priori. [Pg.231]

Another approach to the pulsatile delivery of drugs with an osmotic pressure driven system has been suggested by Amidon et al. [66], This system provides the option of an immediate bolus dose and a second dose that can be timed to be released at some subsequent point following the administration of the dosage form. One or both of the doses can be composed of multiparticulates, for example, that would themselves be sustained release systems. [Pg.452]

These techniques may be coarsely classified into techniques that mimic human reasoning about toxicological phenomena (Expert Systems) and methods that derive predictions from a training set of experimentally determined data (Data Driven Systems). [Pg.81]

The faster rate of growth of e-waste produced in the developing world than in the developed world likely means that by the year 2018, more e-waste will be produced in places unable to process it properly than in places that can [5]. Where it exists as an efficient and pervasive bottom-up market-driven system, the informal sector may best be reformed by specifically targeting its most dangerous practices. [Pg.276]

In a goal-driven system, the inference engine would start with the first rule because the conclusion of that rule is the recommendation of a solvent. [Pg.222]

With respect to calculations of the electronic structure of molecular clusters and their complexes with oxygen, the PM 3 program of the computer-driven system called MOPAC was used. [Pg.111]

Dynamical chaos in periodically driven systems has become attractive topic in many areas of contemporary physics such as atomic, molecular, nuclear and particle physics. Dynamical systems which can exhibit chaotic dynamics can be divided into two classes time independent and time-dependent systems. Billiards, atoms in a constant magnetic field, celestial systems with chaotic dynamics are time independent systems, whose dynamics can be chaotic. [Pg.331]
