A steady‐state, one‐dimensional model kinetic equation with a simple external force and a Lorentz collision term is solved by the approximation methods of moment expansions, by a neoclassical type of asymptotic expansion, and by other simple expa

The survival of very low birth weight newborn infants ofor = 1000 gms cared for in the University of South Dakota School of Medicine/Sioux Valley Hospital Neonatal Intensive Care Unit was analyzed for the 12 year period of 1981-1992. Survival has inc

This study presents findings from 35 interviews with mothers of infants who were monitored for apnea following discharge from the same neonatal intensive care unit. The interviews took place at a mean of 28 weeks following discontinuation of the infa

In order to provide information to assist in the design and planning of workplace air-sampling facilities, we have studied the variations in time and space of aerosol concentrations in a small room containing a glove-box and a heated phantom. Aerosol

Three types of reinforcing material that are used in herniorrhaphy were tested by biaxial straining to obtain their load-extension properties. Steel mesh was by far the stiffest material, followed by porcine skin, then Mersilene mesh, when tested by

The variations in aerosol concentration around a small room and around a phantom have been measured. Even in the steady state the average concentrations at different positions around the room can differ by an order of magnitude. The measured concentr

The results of personal air samples taken in plutonium and uranium handling areas at Harwell Laboratory during 1986 have been examined on a statistical basis. It has been shown that the distribution of the concentrations shown by samples is of log-no

Infrared reflectance spectra are reported for oriented single crystals of MAMC and PAMC with the electric vector parallel to the anionic sheets for temperatures from 50 to 295K. Single-crystal Raman spectra were also obtained at similar temperatures.
