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

Hanford contribution for the nineteenth high temperature fuels committee meeting, November 16, 17, 18, 1964, Los Angeles, California

Description: The irradiation performance of Zircaloy-2 clad thorium-uranium fuel elements under water-cooled power reactor conditions continues to be excellent. Fuel swelling continues to be no more than that required to accommodate the fission product atoms. Measured fuel swelling is less than one percent at 3.1 {times} 10{sup 20} fissions/cc (9,300 MWD/T). The addition of iron and aluminum to metallic uranium fuel elements has been shown to markedly decrease fuel swelling. The improved swelling performanc… more

SPARK-GAP-TRIGGER AMPLIFIER

Description: Short over-all time delay, low time jitter, and excellent long-term reliability are among the desirable features designed into a pulse generator that produces a 2-MW output pulse 30 nsec after the application of a 1-V signal at its 50-ohm input connector. The 10-kV output pulse can be used to trigger simultaneously several spark gaps of the type used in spark-chamber pulse modulators. The 10{sup 8} power gain of the spark-gap-trigger amplifier is achieved by four stages of amplification package… more

Criticality-Accident Dosimetry Studies

Description: Experiments were carried out to (1) explore possibilities for developing a less expensive device than the Hurst threshold detector unit (TDU) for monitoring possible accidental critical reactions in uranium-processing facilities, (2) to study the precision and accuracy of the TDU, and (3) to evaluate the ORNL film badge in mixed neutron-gama radiation fields.
