A new evaluation standard for the dehydrogenation catalysts in the superheated liquid-film states is introduced here. This standard is called as the "ratio of heat recuperation" [39], being defined as the ratio of endothermic reaction heat to the denominator of heat supplied from the external thermo-reservoir to the catalyst layer shown as follows (Equations 13.10 and 13.11) ... [Pg.463]

Third, adequate resources should be made available for reviewing industry submissions and/or for undertaking new evaluations. Since the availability of skilled personnel is limited in some countries, the priority should be on adapting studies from other locations, unless the decision in question has very large resource consequences. [Pg.225]

From the ready-mix producer s point of view, considerations about instability of the air-void system must be linked to a practical measurement of the air content. This raises the question as to how unacceptable spacing factor values can be detected from air content measurement. Since each combination of cement and AEA will produce its own values and the addition of SP will modify the relationship between the air content and air-void spacing, the only way to assess the stability of the AVS in superplasticized concrete is to carry out preliminary test for each cement-AEA-SP combination. It is probable that with several tests of a specific combination of cement-AEA-SP, a relationship between the air content and spacing factor could be estimated with a reasonable degree of precision. But any change of AEA type or brand of cement will make necessary a new evaluation of this relationship. [Pg.530]

The manufacturer must establish the maximum cultivation span for a particular cell in vitro (passage number). The characterization must include the growth rate, morphology, specific yield, and quality of the molecule of interest (Wiebe and May, 1990). The post-production cells (PPCs) must be removed from the bioreactor and tested at least once to evaluate whether new contaminants were introduced or induced by the cultivation conditions. Changes in the culture medium or production scale require new evaluation of the PPCs to determine any effects on the yield and product consistency (Levine and Castillo, 1999). [Pg.355]

Available analysis methods are important for evaluation of the electrocatalytic abilities of electrodes. It is complicated to have a whole estimation system. New evaluation, new technologies, and methods are always needed and also very important for developing new electrode materials. [Pg.346]

The blinded data was the only valid data. However, Eli Lilly ran roughshod over science by breaking the blind in providing its new evaluators data indicating what each of the patients were taking when they were found to have attempted suicide. Thus, when evidence-based ... [Pg.387]

Suzuki, Kato, Fukuda et al. have conducted drop hammer sensitivity tests, friction sensitivity tests, and card gap tests on composite propellants that include nitramine 18 . The authors have conducted safety evaluations in cooperation with engineers from Nippon Oils and Fats Corporation to prove that no detonation propagation exist in composite propellants. We used new evaluating methods 11 131. The outline of our study follows. As new methods were constantly being adopted for the study, our tests were conducted on trial-and-error basis. All of the tests described here are not necessary for the evaluation of the detonating feature in composite propellants. [Pg.318]

In a last filtering step, all duplicate compounds were removed from the dataset. This finally gave 25,017 compounds. After calculating stereoparity values for stereo centers, this dataset was used for the new evaluation study. [Pg.180]

These correction terms involve numerical coefficients (Gear, 1971 see also Allen and Tildesley, 1987) chosen to give optimum stability and accuracy. Ideally, the corrector step would be repeated to improve the accuracy of the estimates at (n+ l)Af but each correction involves a new evaluation of the forces, which is the most time-consuming part of an MD simulation. So in practice just one or two corrector steps are carried out. Other forms of predictor-corrector algorithm exist. A discussion of various MD algorithms has been given by Berendsen and van Gunsteren (1986). [Pg.90]

In the meson-exchange current (MEC) study of two years ago [7], the meson-exchange contribution to Mo was not calculated rather, an effective value was deduced from a least-squares fit to experiment of impulse-approximation predictions for 18 mixed rank-zero and rank-one decays. The major new ingredient which will be presented here is the incorporation of recent new evaluations [9] of the mesonic exchange directly into the calculations and the least-squares fit. [Pg.104]

The equations could easily be written in a simplified form, combining several of the steps. This scheme requires three new evaluations of the force Vt7 per iteration, making it significantly more expensive than the vanilla second-order Verlet method. We may use this fourth-order scheme (now x = 2) to then find a scheme of order... [Pg.110]

After finishing the simulation phase, the ARMS sampled values are used for inferring about the marginal distribution of each unknown variable of interest and any additional information from the approximate functions g is neglected. In the present paper, instead, it is proposed a reasonably accurate approximate function g (due to ASR) which can be improved at every new evaluation of the target FCD (the step 3 of ARMS and MH algorithms). Thus, besides guarantying detailed balance to GGS, a better approximate function is provided. [Pg.64]
