1.6 W continuous-wave Raman laser using low-loss synthetic diamond

Low-birefringence (Δn<2x10−6), low-loss (absorption coefficient <0.006cm−1 at 1064nm), single-crystal, synthetic diamond has been exploited in a CW Raman laser. The diamond Raman laser was intracavity pumped within a Nd:YVO4 laser. At the Raman laser wavelength of 1240nm, CW output powers of 1.6W and a slope efficiency with respect to the absorbed diode-laser pump power (at 808nm) of ~18% were measured. In quasi-CW operation, maximum on-time output powers of 2.8W (slope efficiency ~24%) were observed, resulting in an absorbed diode-laser pump power to the Raman laser output power conversion efficiency of 13%

Growth, reproduction, mortality, and pathologic changes in rats fed gamma-irradiated potatoes

For two years a colony of albino rats was fed diets one-third of which consisted of potatoes which received, for sprout-inhibition purposes, a dose of up to 40 kilorads of irradiation from reactor fuel elements. There were no effects of the irradiation treatment on growth, reproductive performances through four generations, hematology, nor on pathologic changes of these rats. The higher mortality of first-generation males and second-generation females fed the diets containing irradiated potatoes is not believed to be attributable to the irradiation treatment per se. Irradiation was not a factor in the unusually high incidence of a necrotizing arteritis resembling "peri-arteritis nodosa" in the first- and second-generation animals.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32435/1/0000517.pd

Thermospheric composition changes seen during a geomagnetic storm

The largest magnitude winds observed using the instruments on board the Dynamics Explorer 2 (DE-2) satellite were measured during the large geomagnetic storm that occured on the 24th of November 1982. Neutral temperatures exceeded 2000 K during this strom, these high temperatures, combined with the very large observed winds and the very full instrumental coverage available in both hemispheres, make it a unique event to study. In this paper we present results obtained using these DE-2 data and a time dependent simulation of the event made using the National Center for Atmospheric Research Thermosphere/Ionosphere General Circulation Model (NCAR-TIGCM). In general, the agreement between model calcuations and the data is very good, implying that most of the important physical processes controlling the energetics and dynamics of the thermosphere are reasonably well represented in the model. The modelled summer hemisphere changes in the mass mixing ratio of N2([Psi]N2) are in very good agreement with the DE-2 data, and the overall global pattern of [Psi]N2 in the model is also in good agreement with the averaged data in both hemispheres. This agreement allows us to study the physical processes occurring in the model with confidence that they are the same as those occuring in the "real" thermosphere. This short paper describes model-experiment comparisons for the November 24, 1982 geomagnetic storm, but does not include the processes responsible for these changes. A full description of them is available in the set of papers/1,2,3,4/.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29808/1/0000154.pd

Effect of Immunoglobulin Therapy on the Rate of Infections in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation or Treated with Immunomodulatory Agents.

Multiple myeloma (MM) is associated with a significant risk of infection due to immune dysfunction. Infections are a major cause of morbidity and mortality in MM patients. There are few data available regarding the prevalence of infection in MM patients, especially in conjunction with newer generations of immunomodulatory drugs (thalidomide, bortezomib, lenalidomide) or post autologous stem cell transplantation (ASCT). Intravenous immunoglobulin (IVIG) has been used successfully to reduce infection rates in the stable phase of MM, with limited data in other stages

Modelling of time-dependention outflows at high geomagnetic latitudes

In a recent paper, Gombosi and Killeen (1987) applied a highly parameterized thermospheric Joule heat source as a boundary condition in the time-dependent, ion outflow model of Gombosi et al. (1985) to show that episodic ion outflows at high geomagnetic latitudes could result from low altitude ion frictional heating. To delineate more realistically the time-dependent thermosphere/ionosphere environment, we extend this previous study by using output from the Thermospheric General Circulation Model (TGCM) of the National Center for Atmospheric Research (NCAR) as input to the same hydrodynamic polar wind code for a set of case studies which follow the thermal forcing history of individual, ionospheric, convecting flux tubes. Using derived, time-varying frictional heating rates such as those experienced by these flux tubes, we show that transverse ion heating below 500 km can provide sufficient energy to perturb the velocity distribution of the major ion species. The time-dependent flux tube heating results in localized regions of field-aligned O+ upflows. These results demonstrate that localized heating, generated from thermosphere/ionosphere interactions, may initiate heavy ion upwellings which, through further energization at higher altitudes, could evolve into the transient ion outflows as seen by the Dynamics Explorer 1 satellite.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27472/1/0000513.pd

Hanford Tank Farms Waste Certification Flow Loop Test Plan

A future requirement of Hanford Tank Farm operations will involve transfer of wastes from double shell tanks to the Waste Treatment Plant. As the U.S. Department of Energy contractor for Tank Farm Operations, Washington River Protection Solutions anticipates the need to certify that waste transfers comply with contractual requirements. This test plan describes the approach for evaluating several instruments that have potential to detect the onset of flow stratification and critical suspension velocity. The testing will be conducted in an existing pipe loop in Pacific Northwest National Laboratory’s facility that is being modified to accommodate the testing of instruments over a range of simulated waste properties and flow conditions. The testing phases, test matrix and types of simulants needed and the range of testing conditions required to evaluate the instruments are describe

Modelling of composition changes during F-region storms: a reassessment

A recalculation of the global changes of thermospheric gas composition, resulting from strong heat inputs in the auroral ovals, shows that (contrary to some previous suggestions) widespread increases of mean molecular mass are produced at mid-latitudes, in summer and at equinox. Decreases of mean molecular mass occur at mid-latitudes in winter. Similar results are given by both the `UCL' and `NCAR TIGCM' three-dimensional models. The computed composition changes now seem consistent with the local time and seasonal response observed by satellites, and can broadly account for `negative storm effects' in the ionospheric F2-layer at mid-latitudes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29311/1/0000375.pd
