This paper is concerned with solution procedures for the p-median problem: the wellestablished heuristic of Teitz and Bart, and the GRIA (Global/Regional Interchange Algorithm) technique developed more recently by Densham and Rushton. A computational scheme is presented which facilitates efficient implementations in both cases. The mathematical basis for the computational scheme is explained co...

1. The incorporation of [32P]phosphate into phospholipids was measured in slices cut from the pial surface of guinea-pig cerebral cortex; incorporation into the phosphorus of some water-soluble precursors of phospholipid was measured under similar conditions. 2. Slices subjected to overall electrical stimulation at a frequency of 5pulses/sec. differed from control slices in their pattern ofphos...

The facility is located in Colorado Springs and consists of three BART-eligible dry-bottom, wallfired boilers (Units 5, 6, and 7). These boilers fire a variety of coal types, including coal from the southern Powder River Basin, ColoWyo coal (from northwestern Colorado), 20-Mile Foidel Creek coal (northwestern Colorado), and West Elk coal (western Colorado). Due to equipment limitations, these b...

A 53-year-old male patient was referred for evaluation of recurrent erosions of inguinal and anogenital areas, both lower legs and the oral mucosa. In addition, almost all nails and several teeth were lacking, and the residual teeth showed enamel defects. History revealed congenital absence of skin of large parts of the lower legs and widespread blistering in early childhood. Antigen mapping sh...
