ABSORPTION CHANGES IN BACTERIAL CHROMATOPHORES. II. A NEWCHLOROPHYLL-LIKE PIGMENT FROM THE OXIDATION OF CHROMATOPHORES FROMRHODOSPIRILLUM RUBRUM

Description: Evidence is presented which points to (at least) two bound forms of bacteriochlorophyll present in chromatophores of Rhodospirillum rubrum, both of them readily converted to unbound bacteriochlorophyll (abs. max. 770 mu) when the chromatophores are extracted with acetone or ethanol. Controlled oxidation of the chromatophores with Ir(IV) or with Zn(II) and ferricyanide preferentially destroys the more strongly absorbing pigment (abs. max. 880 mu) but brings about only a slight decrease in the ma… more

Advanced reactivity measurement facilities. A description and performance evaluation

Description: The Advanced Reactivity Measurement Facilities, ARMF-I and ARMF-II, are nearly identical critical facilities and are used almost exclusively for measuring reactor physics parameters, such as reactor-spectrum cross sections and resonance integral cross sections. They are, therefore, designed to (a) have large statistical weights for fuels and poisons, (b) be mechanically stable enough to produce reproducible reactivity measurements, and (c) have sensitive instrumentation capable of measuring ver… more

Applied Mathematics Division Summary Report, July 1, 1962 Through June 30, 1963

Description: Summaries of the computer programs initiated or modified are listed, and the programs developed for the GUS digital computer complex are described. Information included in bulletins or newsletters on computers is indicated, and the new routines for the IBM-704, IBM-1401, and GEORGE are listed. The computer equipment (including GEORGE) presently available for computations is briefly described. An automatic data processing system (CHLOE) was developed for spark chamber photograph analysis. It use… more

Atomics International contribution to 19th High Temperature Fuels Committee. Preliminary information, Section II

Description: A description of the fuel elements for SNAP 1OA, SNAP 2, and SNAP 8 was presented at the 17th High Temperature Fuels Committee Meeting, and some of the experimental results obtained in the program were reviewed at the last meeting. This report present some of the more recent detailed findings of the research and development effort on SNAP fuel element materials.

Boiling Studies for Sodium Reactor Safety: Part 2, Pool Boiling and Initial Force Convection Tests and Analyses

Description: Abstract: In fulfillment of the general objective of developing information on two-phase flow required in the safety evaluation of sodium cooled reactors, pool and forced-convection boiling of sodium were studied both experimentally and analytically.

A BRIEF DESCRIPTION OF THE ROVER-TYPE REACTOR, ITS INHERENT SAFETY PROBLEMS AND TEST PROGRAMS

Description: The Rover type reactor is described briefly, and the problems of Rover flight safety are considered. The safety program is described in some detail, and launch pad accidents and post-operation disposal of the reactor are considered. A poison system will be used during reactor assembly and launch.

Calculations on Cylindrical Metal Vacuum Chambers in Pulsed Magnetic Fields

Description: It has been suggested that metallic vacuum chambers might be suitable for pulsed magnets operating at audio frequencies, with pulse widths nominally 1/360 sec. In the present note calculations are given for a simple model of such a system, in order to estimate the effects of field attenuation and eddy current losses. The results of the calculation may be summarized briefly as follows, where the results apply to a cylindrical chamber of non-maeyletic stainless steel, 3.0 cm in inside diameter an… more
