As Marc Shell notes, however, hypothesis is inherently bound up with money. To make a hypothesis is to ask for credit that may be called in later, when a conclusion is reached and meaning exhausted. When Plato criticized the sophists, he simultaneously expressed anxiety about coinage—that is, as a division between symbolic and material value Was not even Socratic dialectic. . . pervaded by the monetary form of exchange Was not dialectical division a kind of money changing, and dialectical hypothesizing a kind of hypothecation, or mortgaging (Shell 2). 

Stress calculations are carried out by the finite element method. Here, the commercial finite method code ABAQUS (Hibbit, Karlsson, and Sorensen, Inc.) is used. Other codes such as MARC, ANSYS are also available. To calculate the stresses precisely, appropriate meshes and elements have to be used. 2D and shell meshes are not enough to figure out stress states of SOFC cells precisely, and thus 3D meshes is suitable for the stress calculation. Since the division of a model into individual tetrahedral sometimes faces difficulties of visualization and could easily lead to errors in numbering, eight-comered brick elements are convenient for the use. The element type used for the stress simulation here is three-dimensional solid elements of an 8-node linear brick. In the coupled calculation between the thermo-fluid calculation and the stress calculation a same mesh model have to be used. Consequently same discrete 3D meshes used for the thermo-fluid analysis are employed for the stress calculation. Using ABAQUS, the deformations and stresses in a material under a load are calculated. Besides this treatment, the initial and final conditions of models can be set as the boundary conditions and the structural change can thus be treated. 

It is interesting to read what "captains of industry," such as the chairmen of prominent multinational companies, have to say about sustainable development. Sir Marc Moody-Stuart, former chairman of the Committee of Managing Directors of the Royal Dutch/Shell Group of Companies, stated in 1999 in Ref. [5] what sustainable development meant for his company "balancing our own legitimate commercial interests with the wider need to protect and enhance the environment and contribute to social progress and stability."... 

Solvent can be removed from the marc by heating with heat supplied by the outside shell, injecting steam, or pulling a vacuum on the extractor. Solvent-free marc is dumped out the bottom of the extractor. Extractors capable of vacuum operation are available to handle 70-450 kg (150-1000 lbs) of raw material. Much larger capacity is available for nonvacuum systems, up to 6800 kg (15,000 lb) loads. 

Recently, a combination of closed-shell singlet, open-shell broken symmetry singlet and spin triplet DFT calculations was used to probe the reaction coordinate for nitrite reduction catalyzed by mARC. Regarding an oxyl radical transfer mechanism (Figure 2.36), the computed reaction barrier (AH was found to be 14 kcal moF. This reaction is approximately thermoneutral since Mo(v) dioxo species are very unstable toward proton-ation. However, protonation of the equatorial oxo is expected to lead to an overall increase in the exergonic nature of this reaction (Figure 2.36). However, if the 0 oxygen of N02 that is coordinated to the Mo(iv) ion is... 

After having received his PhD in 1985 at KU Leuven, Marc F. A. Hendrickx was the second researcher to join the theoretical chemistry group of this university as a permanent member of the academic staff. Since then, the main focus of his research activities has been on the study of properties of a wide variety of transition metal compounds. His recent research activity is mainly directed toward applying quantum chemical methods on small transition metal-containing clusters. Their frequently complicated open-shell electronic structures are studied in relation to their magnetic and spectroscopic properties.
