Highest possible setting

Moreover in a classical factorial design, in the case of linear relationships, only two conditions for each independent variable should be tested at the lowest and highest possible setting. If the dependent variable is a function of three independent variables (A, B, and C), each of which can take on two possible values or levels, then to test all possible variable combinations the number of experiments is equal to the number of levels, N, raised to the power of the number of independent variables, n, e.g. N" = 23 = 8 (Figure 10.5 and Table 10.2). 

The World Health Organization (WHO) is the UN s specialized agency for health. It was established in 1948. WHO s objective, as set out in its constitution, is the attainment by all people of the highest possible level of health. Health is defined in WHO s constitution as a state of complete physical, mental and social well-being and not merely as the absence of disease or infirmity. 

There are several parameters which need to be optimised for the achievement of fhe highest possible CT enhancement with minimal line-shape distortion. With optimal settings, HS and other adiabatic pulses usually give the highest enhancements (close to the theoretical limits of 21 for perfecf ST inversion), when compared to other methods such as DFS and Even without detailed optimisation, it is usually found... 

The objective of the die is to achieve the desired shape within set limits of dimensional uniformity at the highest possible production rate. However, nonuniformities can arise in the Anal part and are classifled according to their geometry. The first type of nonuniformity is in the machine direction, or direction of flow [z direction, part (a) in Figure 7.55]. These arise due to time variations of inlet temperature, pressure and composition of the melt. The second type of part nonuniformity is in the crossmachine direction [perpendicular to the z direction, part (b) in Figure 7.55]. These are generally due to improper die design. 

Suppose the user thinks that the prior qm ought to have values near a definite set of number Qm, called biases. Suppose also that the user wants to express this suspicion with the highest possible conviction. Then the user asserts that there is no spread possible about the Qm, or... 

The engineering objectives of die design are to achieve the desired shape within set limits of dimensional uniformity and at the highest possible production rate. This chapter discusses both objectives, but the question of die-formed product uniformity deserves immediate amplification. To understand the problem, we must distinguish between two types of die-formed product nonuniformity (a) nonuniformity of product in the machine direction, direction z [Fig. 12.2(a)], and (b) nonuniformity of product in the cross-machine direction, direction x [Fig. 12.2(b)]. These dimensional nonuniformities generally originate from entirely different sources. The main source of the former is the variation... 

In the modem type of electrolyzers the electrodes are set closer together approximately 14—20 mm apart. The cathodes are corrugated and the anodes are shaped according to the corrugations. In this way it was possible to raise current density to some 15 A/sq. dm. In order to achieve the highest possible current efficiency a part of the electrolyte is continually removed from the electrolyzer, resaturated with sodium chloride and returned to the bath. The voltage across the electrolyzer amounts to 3.5 to 3.8 V. Electrolyzers for 12 000 to 24 000 A have been constructed for which less floor space was needed. These modem electrolyzers require 230 to 240 kw-hr. of direct, current and 153 kg of NaCl to produce 100 kg of 100 per cent Bodium hydroxide. 

The physical meaning of the term /i jj, is the current density achieved if all surface reactions are exergonic (i.e. the highest possible turnover frequency per site). The term jxxmii is dependent on the number of active sites per area and potential independent surface reactions. This means that / miii is dependent on the catalyst material. However, if similar surfaces are compared (e.g. a set of 110 rutile oxide surfaces), the number of active sites per area only varies with a few presents, as the lattice constants are very similar, and y limit can effectively be considered material independent, unlike exchange current density. In that case, trends in fy°ER should correlate with trends in activity, ya. 

Each type of specimen offers a unique set of challenges in obtaining 3D structural information at the highest possible resolution. The best resolutions achieved by 3D EM methods to date, at about 3-4 A, have been obtained with sever thin, 2D crystals, in large part because of their excellent order.
