The problem of the steady state flow of suspensions of charged particles near the entrance of a cylindrical tube has been studied. Axial diffusion has been neglected and an analytical solution obtained when the laminar flow is Poiseuille and plug. The effect of the electrostatics on deposition is given and the results compared with the existing numerical solutions.
We study makespan minimization on an m machine flowshop. No idle time is allowed between consecutive Free Run 2
operations on each machine. We introduce an efficient (O(n2)) greedy algorithm, which is shown numerically to perform better than a recently published heuristic.
Studies on the interactions of quartz particles with macrophages have contributed considerably to a better understanding of the mechanisms eventually leading to lung fibrosis. The aim of this study was to compare the effects of a number of test or standard quartz materials on alveolar macrophages from different species. Also Nike Free Running Canada
the geometry of exposure was varied.
A label dosimeter system utilizing a polydiacetylene as a radiachromic element printed on a bar code label and a portable hand-held computer to read the label dosimeter has been developed. Results of an evaluation of the effects of time, temperature, humidity, dose rate, and light on the response of the indicator are presented.
