TL;DR: The authors compared the professional activities of retired professors from liberal arts colleges, a comprehensive university, and a major research university and found that a large majority of faculty continue to perform professional roles and that strength of ties to colleagues and professional organizations outside the institution are correlated with professional activity at all types of institutions.
Abstract: This study compares the professional activities of retired professors from liberal arts colleges, a comprehensive university, and a major research university. Results show that a large majority of faculty continue to perform professional roles and that strength of ties to colleagues and professional organizations outside the institution are correlated with professional activity at all types of institutions. Major differences among institutions are: (1) liberal arts college and research university faculty show consistency between pre- and postretirement professional activity levels, whereas comprehensive university faculty do not; (2) university faculty show higher levels of participation in a number of professional activities than do liberal arts college faculty; (3) rated importance of “research or other creative work” is related to professional activity for comprehensive university faculty and rated importance of “consulting” and “university service” are related to professional activity for research university faculty.

TL;DR: In this paper, the McNabb-Foster equations were applied to the data reported earlier by Lauf and Altstetter for the diffusion of oxygen in dilute niobium alloys.
Abstract: The McNabb-Foster equations, solved using a finite difference approach, have been applied to the data reported earlier by Lauf and Altstetter for the diffusion of oxygen in dilute niobium alloys. It was assumed that the substitutional alloy atoms acted as traps for the oxygen. Ratios of the release coefficient to the trapping coefficient,p/k, were calculated at various temperatures by computer-assisted curve fitting. Trapping energies obtained from plots ofp/k vs 1/T agree fairly well with those reported earlier using the Oriani model, but differ somewhat from those obtained using a recent model proposed by McLellan. The merits and limitations of the models with respect to the treatment of experimental data are discussed. Initial fractional trap occupancies were also calculated for these alloys and plotted against 1/T, and the results are also discussed.

TL;DR: In this paper, a comprehensive study is made of the global and limit behavior of integral curves in the three-dimensional phase space for the system of nonlinear ordinary differential equations governing the structure of combustion shock layers.
Abstract: A comprehensive study is made of the global and limit behavior of integral curves in the three-dimensional phase space for the system of nonlinear ordinary differential equations governing the structure of combustion shock layers An important general result is a list of admissible routes for the integral curves representing the four combustion types Most noteworthy is a theorem on the nonexistence of strong deflagrations A special aspect of this study suggests the significance of the stoichiometric parameters for a reaction and the need to distinguish between first-order and higher-order reactions It is thought that the detailed information on the various possible modes of combustion for the different reactions will be of use in the search for efficient energy conversion by combustion processes
