Antibody Formation by Transplanted Bone Marrow, Spleen, Lymph Node and Thymus Cells in Irradiated Recipients

Description: The role of the marrow as a site for antibody formation has been considered for many years. In 1912 Ludke reported the appearance of antibody in cultures of marrow cells obtained from previously immunized rabbits. Specific agglutinins for killed typhoid bacilli and lysins for ox red cells and sheep red cells were detected in the culture media 2 to 5 days later. However, the cultured cells failed to produce antibody when these antigens were added to the media. Similar findings by Reiter, Przygod… more

Crystal Structure of a Sodium Cobalt Molybdate

Description: The cobalt and molybdenum positions had been derived from a three-dimensional Patterson function based on complete data out to λ-1 sin θMo≈ 1. From the separation of the separation of the Mo atoms it was thought that the structure contained free, unlinked MoO4 -2 ions, and this, together with the observed density and analyses for Co and Mo, suggested that the composition was probably Co2(MoO4)3. The paucity of structural information on complex oxide systems and the interesting properties, both … more

Draft of physics sections to 100-N technical manual

Description: The information presented is a collection of most of the physics information available for the New Production Reactor. The details of some of the physics information, particularly those dealing with exposure and temperature effects, are by no means to be considered the final word since there has been no experimental verification of these effects. However, the gross physics characteristics described are felt to be reasonable representations of the expected physics behavior of N Reactor and shoul… more

Effects of Low Levels of X-Rays and Irradiation from C14 and H3 on Cell Population Kinetics in the Root Tip of Tradescantia

Description: Reciprocal labelling in double-labelling experiments with H3- and C14- thymidine showed that when H3- thymidine (1μc/ml for 0.5 hr) was given first in the labelling sequence followed by a 4 hr interval before the C14- thymidine treatment, that passage of cells into and out of DNA synthesis was normal. When C14 was first in the sequence, the rate at which cells entered DNA synthesis was decreased. This was attributed to a radiation effect produced by the β-rays from the C14. The rate at which ce… more

Electrical Design of Electrostatic Deflectors for Sector-FocusedCyclotrons

Description: The new sector-focused cyclotrons have more energetic and better focused beams at the extraction radius than do ordinary cyclotrons. While the first characteristic requires a more intense electric field, the second permits this field to extend over a smaller volume. By tailoring the electrode geometry to these characteristics of the beam, the required deflector gap and electrode surface become smaller, and a higher gradient can be held without sparking. A different compromise between radioactiv… more

Fast Analysis System for Bubble Chamber Data

Description: A type of precision measuring instrument, a flying spot digitizer, for the analysis of bubble chamber data is described. When the flying spot encounters a bubble image, it is attenuated typically 25 to 75% depending on the directness of hit and the bubble chamber photographic and operating parameters. The width of the bell-shaped attenuation curve is approximates the sum of the spot and bubble image diameters, or 40 to 50 mu . The high precision of the FSD derives from the fact that it is possi… more
