Efficiency, of transport

With a typical ablated particle size of about 1 -pm diameter, the efficiency of transport of the ablated material is normally about 50% most of the lost material is deposited on contact with cold surfaces or by gravitational deposition. From a practical viewpoint, this deposition may require frequent cleaning of the ablation cell, transfer lines, and plasma torch. [Pg.112]

When changing the kind of acids with relatively higher lipophilicity, the efficiency of transport is lowered by the leak reaction based on their ease of transfer across the liquid membrane 16). (Table 3) It is noteworthy that 12, which has trimethylene chains, shows selectivity for Li+ much better than 13, which has ethylene chains 17). (Table 4)... [Pg.41]

Highly viscous petroleum oil containing 30% to 80% water can be transported through pipes more efficiently when a 1 1 mixture of washing liquid and antifreeze (i.e., ethylene glycol with borax) is added to the oil in amounts of 0.002% to 0.2% by weight. In addition to increased efficiency of transport, reduced corrosion of pipes can be achieved [893]. [Pg.191]

LHE is the light harvesting efficiency or absorptance, defined as LHE = 1-10" where A is the absorbance, ( )inj is the quantum yield of charge injection, and r is the efficiency of transporting injected electrons in to the external circuit. Equation (3.6.26) can be written as ... [Pg.178]

FDG is readily taken tip by this transport system, although the extent of uptake can be influenced by the concentration of plasma glucose, which competes with FDG for uptake. The efficiency of transport across the blood brain barrier is such that blood flow is generally not limiting for tracer delivery but the potential for a drug to have a direct vascular effect that influences tracer delivery should be considered. [Pg.217]

There is experimental evidence for the dependence of efficiency of transport or chemical processes in biological systems. Many studies have... [Pg.332]

Transport is the process of transferring or conveying something from one place to another. Transportation is the process of transporting. The transportation of people, goods, funds, and information plays a key role in any economy, and the industrial engineer can play a key role in properly balancing the parameters and constraints that affect the effectiveness and efficiency of transportation systems. [Pg.788]

The Prandtl number is a dimensionless number that provides a measure of the efficiency of transport by momentum diffusivity to thermal diffusion ... [Pg.248]

When studying the transport of a poorly charaeterized RNA, a good place to start is with a transport time course. Here, the time course of transport, percentage efficiency of transport at equilibrium, and stability of the microinjected RNA are assessed in comparison to coinjected standard RNAs. The end point of the time course will reflect the steady-state or equilibrium nucleocytoplasmic distribution of the RNA. Because transport varies significantly from ooocyte to oocyte it is usually necessary to perform each time point in triplicate, with at least 5-10 oocytes per trial in order to estimate the standard error. [Pg.579]

Note that the storage of energy is difficult and the locations of energy offer and that of energy demand can be rather distant. This requires high efficiencies of transportation systems and much international cooperation in the future. [Pg.9]

The interaction between the screw and the media handled introduces a behaviour relationship, which must be satisfied for effective operation. The mechanical efficiency of transport is low in comparison to belt conveyors, where the bulk material is less disturbed in transit. [Pg.6]

For high efficiency of transport, the receiving end should contain a significant concentration of the separating component. [Pg.291]

The efficiency of transport of sample solution to the premixed flame is usually between 5% and 10%. Other more elaborate devices, such as the ultrasonic type, do somewhat better and are preferred in some applications, but are seldom used in flame photometry. [Pg.214]

This efficiency of transport term is a function of the conveying conditions through two equipment terms, the dynamic material coefficient (F) and the vibration angle ((3), as well as material-dependent terms. The material dependence will be based on wall and internal friction, material shear strength or cohesion, particle size and density and almost... [Pg.231]

The effective number of electrons transferred increases with the electrode size since the efficiency of transport via convergent/divergent diffusion to or from the electrode decreases. Hence, the species Ox spends more time close to the electrode than is the case when the electrode is very small. Accordingly, there is more time available for the reaction with Z to produce Red that will be able to react further at the electrode, and hence a greater catalytic activity. [Pg.106]

Proposed mathematical model implemented into PTV Visum environment bases on representation of full railway and road transport network of Poland with appropriate transition points. Model uses complete ODO matrixes for segments of demand for freight transport and uses full structure of vehicles for both modes. These elements allow for testing efficiency of transport system of Poland according to different aspects, like environmentally friendliness resulting from emission patterns. Emission levels are implemented into the model as functional dependences gained from on-board surveys (Merkisz et al. 2014, Mierkish Pielecha 2014). [Pg.566]

Once the technology shift has taken place, several additional functionalities are foreseeable. They range from new approaches to provide drivers with adapted vision information to solutions for how available vision information can be transferred between vehicles and infrastructure to extend usability in new ways. The more intelligent transport systems supported by these leaps in development result in an increased efficiency of transports and safety for the drivers of commercial vehicles as well as other road-users. This would have clear positive effects not only for transport and traffic but for the entire society. [Pg.171]
