Reduction parameter

Experimental results for the Slater parameter reductions of Nd3+, Pr34-, and U3+ (Troster et al 1995) in LaCl under pressure up to 8 GPa in comparison with results from the dielectric screening model. All values in cm 1 3... 

As a first application of the model of coke deposition we have described the impact of coke on the cracking reaction. As the cracking reaction is hardly affected by the catalyst but dictated by temperature and residence times, the impact of coke is via the latter parameter (reduction of the hold up of the fluid phases). The results in Figure 9 show that a very good performance description is thus obtained. 

NMR-SIM can be seen as a software tool to analyse separately the effects on a NMR spectrum of different experimental variables such as spin system, pulse sequence and experimental parameters. The simulation program reduces the number of experimental parameters to a minimum to resemble as closely as possible a real experiment. This reduction in the number of variable parameters is a basic principle of scientific research because often the relationship between only a limited number of parameters can be interpreted unambiguously. The parameter reduction also speeds up calculation time. As illustrated in Fig. 4.1 the NMR spectrometer, represented by the magnet and computer, can be replaced by a computer plus software and the NMR sample by a defined theoretical spin system. Such an "ideal spectrometer" is the basis of the NMR-SIM or NMR experiment simulator software tool. 

The dependence of sorption isotherms upon pretreatment is an example of the hystereses which can bedevil models which rely on effective parameter reductions of subtle sub-scale processes. In delicate regimes, models at a... 

Fig. 13. Spondyloptosis with changes in the positional and spinal parameters. Reduction of spondyloptosis with improvement of the positional and spinal parameters. One year after surgery further improvement of the parameters with normalization of the projection of the gravity line. Three years later unchanged positional parameters of the lumbo-sacral hinge, but further alignment at the spinal parameters with complete normalization of the course of the gravity line...

The temperatme dependence of the lattice parameters are shown in Fig. 35d [97L1]. The water decomposition causes a step decrease of the cell parameter. In the terrperature range from 150. .. 250 °C there is a moderate decrease of the imit cell. Above 250 C, the breakdown of the structure is shown by starting of a further steep cell parameter reduction accompanied by peak broadening. 

To account for the material evolutions, guidelines dedicated to the external or internal reinforcements of concrete structures using FRP composites usually introduce substantial durability parameters (reduction factors on FRP tensile properties and on shear characteristics of FRP/concrete bonded interfaces, creep stress levels and fatigue limits) see, for instance, ACI 440.2R-08 (2008) and ACI 440.1R-06 (2006). However, further research is still needed to refine the design codes and better calibrate the durability reduction factors taking into account synergistic effects between various environmental factors. 

Simulation analysis of cyclic voltammograms has typically been done by visual comparison of experimental and simulated data. Many simulations are performed, varying unknown parameters (reduction potentials, rate constants, etc.), until a good visual fit is obtained. An alternative, more rigorous, approach is to make a quantitative comparison of the entire cyclic voltammogram with that predicted by theory. 

Less strict reactivity control requirements due to low power density (reduced power and Doppler reactivity effects) and the lower operating point parameters (reduction of the absolute value of moderator coefficient). 

ABSTRACT In the era of informatization databases and information systems are an essential source of risk analysis and risk assessment of collective water supply systems. The functioning of the water distribution system is associated with the risk of occurrence of undesirable events. The result of these events may be deterioration of the water quality parameters, reduction of water pressure in the water network or total lack of water. 

Hence, the stated above results showed that PHE molecular weight changes at water-isopropanol ratio variation in reactionary mixture could be described quantitatively within the frameworks of irreversible aggregation models and fractal analysis. The indicated ratio change defines interactions polymer solvent change that results to macromolecular coil stracture variations. An interactions polymer solvent weakness, characterized by Flory-Haggins interaction parameter reduction, results to...
