THE SPARTAN SCHOOL OF INSTITUTIONAL ECONOMICS AT MICHIGAN STATE UNIVERSITY
No full textHeterodox scholarship at Michigan State University (MSU) was influenced by the institutional economics of John R. Commons at Wisconsin. But it was far from monolithic and had many other sources and originality of its own. A case can be made that the center of institutional economics moved across Lake Michigan from Madison to East Lansing and blossomed in the second half of the 20th century with such Wisconsin Ph.D's as Raleigh Barlowe, Warren Samuels, Allan Schmid, Harry Trebing, and others. Equally important in making MSU a center of institutional economics were scholars from other institutional backgrounds such as Paul Strassmann, economic development; Robert Solo, science and technology; James Shaffer, agricultural marketing and consumer behavior; Nicholas Mercuro, law and economics; and others.Institutional and Behavioral Economics,

Carbon nanotube grafted carbon fibres: A study of wetting and fibre fragmentation
No full text26/09/12 meb. Author version, OK to pub.Carbon nanotubes (CNTs) were grafted on IM7 carbon fibres using a chemical vapour deposition method.The overall grafting process resulted in a threefold increase of the BET surface area compared to the original primary carbon fibres (0.57 m2/g). At the same time, there was a degradation of fibre tensile strength by around 15% (depending on gauge length), due to the dissolution of iron catalyst into the carbon;
the modulus was not significantly affected. The wetting behaviour between fibres and poly(methyl
methacrylate) (PMMA) was directly quantified using contact angle measurements for drop-on-fibre systems and indicated good wettability. Single fibre fragmentation tests were conducted on hierarchical fibre/PMMA model composites, demonstrating a significant (26%) improvement of the apparent interfacial shear strength (IFSS) over the baseline composites. The result is associated with improved stress transfer between the carbon fibres and surrounding matrix, through the grafted CNT layer. The improved IFSS was found to correlate directly with a reduced contact angle between fibre and matrix
NEW TERMS IN THE POTENTIAL FUNCTION OF THE

These difficulties led to a reexamination of the paper on the theory of the linear molecule by Shaffer and From this study it became apparent that several permitted terms had been omitted from the cubic and quartic portions of their expression for the potential energy, namely: {hc}\beta_{345}{q}_{3}({r}_{4}{s}_{5}-{r}_{5}{s}_{4}), \quad {hc}\Sigma^{2}_{{i}=1}\gamma_{i 354}{q}_{1}{q}_{3}({r}_{4}{s}_{5}-{r}_{5}{s}_{4}), \quad {hc}\gamma^{\prime}_{4455^{({r}_{4}{s}_{5}-{r}_{5}{s}_{4})^{2}}} and , where the notation is the same as in the original paper. With polar coordinate substitutions the above terms may all be seen to depend upon the phase angle between the degenerate vibrations and . As they have symmetry it seems reasonable to include them in the potential energy expression. The new terms affect the energy of the molecule by contributing to , , and , and by introducing an entirely new constant which is the coefficient of . While the contributions to , and do not affect the interpretation of the spectrum or the experimental values previously obtained for them, the new constant does affect the agreement between theory and experiment; the interpretation and assignment of the bands; and the values obtained for several of the other constants. The experimental value of was found to be . The new terms become important in the accidental degeneracy involving and , which are separated by only . A resonance between these levels is postulated in order to make their observed positions consistent with data from other observed bands. The term has non-zero, off-diagonal matrix elements, connecting the upper levels of these bands, which remove the difficulty about their position, while the Shaffer-Nielsen potential function contains no such terms

A simple technique for constructing optimal complete diallel cross designs
No full textA general construction technique is developed for complete diallel cross designs laid out as nested balanced incomplete block designs with sub-block size two. This technique is applied to balanced incomplete block designs with nested rows and columns to establish several series construction plans. Each of these plans yields a class of universally optimal complete diallel cross designs.
