Radioactivity and its relationship to oceanic food chains

Gamma-ray spectra of some primary producers (single-cell plants), filter-feeding herbivores, and carnivores, assigned to trophic levels I, II, and III–V, respectively, were prepared from marine samples taken in the Pacific off Oregon during 1961–1962. These organisms had been exposed in their natural environment to both fission produ cts from fallout and neutron-induced radionuclides from reactors on the Columbia River...

The effect of homogenization at different pressures on the physical properties of an ice cream mixture and the resulting ice cream

Cytolytic T Lymphocytes Specific for Tumors and Infected Cells from Mice with a Retrovirus-induced Immunodeficiency Syndrome.

LP-BM5 retrovirus complex-infected C57BL/6 mice develop immunodeficiency, somewhat analogous to AIDS, termed murine AIDS (MAIDS). After secondary stimulation with syngeneic B-cell lymphomas from LP-BM5-infected mice, C57BL/6 mice produced vigorous CD8+ cytotoxic T lymphocytes specific for MAIDS-associated tumors. An anti-LP-BM5 specificity was suggested because spleen and lymph node cells from LP-BM5-infected mice served as target cells in competition assays, and cells from LP-BM5, but not ecotropic, virus-infected mice functioned as secondary in vitro stimulators to generate cytotoxic T lymphocytes to MAIDS tumors

A study of concept options for the evolution of Space Station Freedom

Two conceptual evolution configurations for Space Station Freedom, a research and development configuration, and a transportation node configuration are described and analyzed. Results of pertinent analyses of mass properties, attitude control, microgravity, orbit lifetime, and reboost requirements are provided along with a description of these analyses. Also provided are brief descriptions of the elements and systems that comprise these conceptual configurations
