PRESTO

Presto, a third-order rate law This multiplication should not be taken as representing a chemical event or as carrying such implications it is only a valid mathematical manipulation. Other similar transformations can be given,2 as when one multiplies by another factor of unity derived from the acid ionization equilibrium of HOC1. (The reader may show that this gives a second-order rate law.) These considerations illustrate that it is the rate law and not the reaction itself that has associated with it a unique order.

The modeling of the internal pore diffusion of a wax-filled cylindrical single catalyst pore was accomplished by the software Comsol Multiphysics (from Comsol AB, Stockholm, Sweden) as well as by Presto Kinetics (from CiT, Rastede, Germany). Both are numerical differential equation solvers and are based on a three-dimensional finite element method. Presto Kinetics displays the results in the form of diagrams. Comsol Multiphysics, instead, provides a three-dimensional solution of the problem. 

Assuming that there are only axial and no radial concentration gradients in the pore due to the negligible size of the pore diameter, the modeled concentration profiles of CO, H2, and H20 in a wax-filled cylindrical pore are given in Figure 12.2 (left, Presto Kinetics). For verification reasons of the underlying model and to obtain a better visual impression of the respective processes in the catalyst pore,...

The data derived from modeling at different conversion degrees (X = 5, 40, and 80%) were also compared to the results obtained from the calculation of the classical Thiele modulus. The calculated (by the Thiele modulus) and modeled (by Presto Kinetics) effectiveness factors showed comparable values. Hence, the usage of simulation software is not required to get a first impression of the diffusion limitations in a Fischer-Tropsch catalyst pore. Nevertheless, modeling represents a valuable tool to better understand conditions within a catalyst pore.

Ready-made Sephadex G-25 columns are available for use with gravity feed (PD-10) or syringe (HiTrap) from Amersham Biosciences. The PD-10 columns with a bed volume of approx 9 mL are very suitable for processing samples of 1-2 mL. Similar cross-linked dex-tran devices, Presto and Kwik columns, are available from Pierce (Rockford, IL).

Many of the trials involved a small number of patients, many times of < 100. The results, therefore, were not reproducible in larger, multicenter trials such as the PRESTO trial.

However, there is still the question of where we are going to put those pesky equivalence limits. In the first case, we will adjust them nice and close to zero, then even our pathetic effort will cause a practically significant difference. For the latter two, we will invent some reason to set them generously wide and hey presto, we are equivalent or non-inferior .

Recently, a new type of machine was introduced to mimic production presses on a small scale. Known under a brand name of Presster — kind of an agglomeration of the words press, presto, and tester — this machine can be classified as a mechanical compaction simulator. 

Ultrafont + makes multicolor easy. You don t have to keep track of bit pairs any more than you have to convert binary to decimal. Just press the f5 key. Presto—the whole screen changes. The normal characters are rather unrecognizable, and the drawing cursor is twice as wide (since eight bits have been reduced to four pixel-pairs, making each dot twice as wide). You have only four dots horizontally per character, but you can easily combine several characters to form larger shapes.
