We are reporting a series of eight patients ranging in age from 3 to 10 years who sustained plantar-flexion injuries of the foot, resulting in injuries to the tarsometatarsal (TMT) interval. All injuries were identified within 3 days and treated with

We have conducted a number of experiments in order to ascertain the temperature dependence of the rate of energy transfer between rare earth ions in solids. The mechanism of such dependence is peculiar to each donoracceptor pair. We report typical ex

In this paper we investigate the fundamental and general features of the energy transfer processes that take place in laser-type crystals. We start by looking at the basic problem of energy transfer in solids and setting the proper framework for its

A new laser crystal Lu3Sc2Ga3O12:Nd3+ with ordered garnet structure is developed. Its stimulated emission at 1.0622 μm wavelength (4F3/2 4I11/2 generating channel) with laser-diode and Xe-flashlamp pumping at room temperature is excited. For prospec

Several NASA programs designed to monitor the Earth's atmosphere from space utilize infrared detectors which operate at or below 4.2 K for optimum performance. At present, the detectors are maintained at cryogenic temperatures by a stored volume of l

The potential for using high-temperature superconductive elements, screen-printed onto ceramic substrates, as thermal bridges to replace the currently employed manganin wires is studied at NASA-LaRC. Substrate selection is considered to be the most c

Currently, research is being conducted on the optical properties of materials associated with the development of solid-state lasers in the 2 micron region. In support of this effort, a mathematical model describing the energy transfer in a holmium la

The processes that take place in the excited states of a trivalent Thulium (Tm) ion in an Yttrium Aluminum Garnet (YAG) crystal, being relevant to the use of this system for laser applications, have been the object of several studies. We have reexami
