Secondary Tetanus Antitoxin Responses in Mice Elicited Prior to Irradiation

Description: The pioneer study by Benjamin and Sluka in 1908 on inhibition of antibody formation by X-rays revealed the importance of the temporal relationship between exposure to radiation and injection of antigen. X-radiation delivered three days before injection of beef serum inhibited precipitin formation in rabbits. A similar exposure to X-rays delivered three days after injection of the antigen failed to repress production of specific antibody. These observations were partially confirmed in 1915 when … more

Radiation - Induced Mammary Gland Neoplasia in the Rat

Description: In discussing this subject, data on radiation induced mammary gland neoplasia in the rat indicating that direct interaction between the radiation and target tissue is necessary for maximum neoplasia induction will be presented mainly. Other types of radiation induced neoplasia, in which little or no information on the mechanisms involved is available, will be discussed briefly. In particular, investigations on radiation induced mouse lymphoma will be reviewed, in which neoplasia appears to be a… more

Hydrides Of Germanium, Tin, Arsenic And Antimony

Description: Volatile hydrides may be prepared from ether solutions by the reaction of the appropriate chlorides with lithium hydroaluminate. In this general method, it is necessary to work with strictly anhydrous reagents and solvents because of the great reactivity of lithium hydroaluminate toward water. The procedures described here are believed to be much more convenient because the reducing agent employed is potassium hydroborate, which is relatively insensitive toward water. Since only aqueous solutio… more

Fast Pulse-Amplitude Discriminators

Description: Pulse-amplitude discriminators are useful in nuclear counting to separate signals of greater amplitude from a background of unwanted or noise signals of lesser amplitude. As used here, the term "fast" implies circuits capable of responding to pulses between a nanosecond and a microsecond in duration. An ideal discriminator would produce for any incoming signal whose amplitude is greater than a threshold bias level, an output pulse of constant amplitude, duration, and delay with respect to the i… more

Contribution of Neutral Pions to Photon-Proton Scattering

Description: "The correction to photon-photon scattering processes due to the existence of the particles other than electrons is reported. The correction is of the same order in the electric charge as the lowest order term in the perturbation expansion in quantum electrodynamics, although the relevant corrections to the electron-photon and electron-electron scattering are all of higher order."

Hamiltonian Dynamics of Relativistic Particles

Description: "The canonical (hamiltonlan) formulation of a relativistic dynamical theory is outlined, and the existence and explicit construction of general hamiltonian theories of relativiatic interacting particles are discussed. These hamiltonian theories are shown to contain certain elements of arbitrariness which are eliminated in manifestly coveriant formulations."

Containment in Cusped Plasma Systems

Description: "A survey of the current theoretical picture of plasma containment in cusped magnetic configurations is presented together with a mention of the points of contact which exist or might soon be made to exist with experiment. A theory of containment was developed which is applicable to the whole range of plasma densities from a tenuous plasma in an essentially vacuum magnetic field to a fully developed plasma which completely excludes the magnetic field from its interior. Also presented are cursor… more

Alternating Direction and Semi-Explicit Difference Methods for Parabolic Partial Differential Equations

Description: "The energy method is applied to study the stability of two types of difference approximations to parabolic partial differential equations, the alternating direction methods Douglas, Peaceman, and Rachford, and a new semi- explicit method. Each difference scheme is proved to be unconditionally stable. These results apply to parabolic equations with variable coefficients, defined in cylindrical domains with an essentially arbitrary bounded base."

The Effect of Temperature on the Width of a Small-Amplitude, Solitary Wave in a Collision-Free Plasma

Description: "Adlam and Allen and Davis, Lust, and Schluter have studied nonlinear plane-waves, propagating normal to the magnetic field, in a cold plasma. One solution of particular interest is a solitary wave, or single pulse. We present a method for solving the analogous problem for a plasma with finite temperature, in the limiting case where the amplitude of the wave is small and where, consequently, the width of the waver is very large."

Nuclear Track Image Intensifier

Description: "Design and fabrication techniques were improved so that the large area image intensifier now performs well in image intensifier systems for photographing nuclear tracks. Two successful samples meeting most of the objectives were completed and started in circulation among members of the AEC Image Intensifier Committee for evaluation in systems to record nuclear tracks. Except for a reported long decay in the P-15 phosphor performance was quite good. Resolution, gain, and background requirements… more

On Certain Finite Difference Schemes for the Equations of Hydrodynammics

Description: "We will consider two finite difference schemes for the solution of the Navier-Stokes equations in one space dimension. The first is a method used by Lax and Wendroff. The second method is based on an approximate solution of the centered, implicit difference equations. Since this approximate solution is obtained by successive substitutions, we will refer to this second method as an iterative method."

Separation of Beryllium from Fission Products in a Nitrate Medium - Preliminary Experiments Using Solvent Extraction

Description: Preliminary experiments using acetylacetone in the presence of ethylenediaminetetraacetic acid to separate major quantities of beryllium from fission products are reported. Using 2M beryllium solutions, decontamination factors of the order of 10/sup 3/ were obtained with trace quantities of the more important fission products. This is sufficiently encouraging for the work to be repeated at higher activity levels.

The Inclusion of Grey Slabs in the Finite Difference Neutron Diffusion Approximation

Description: An analysis of the behavior of the asymptotic flux on either side of a strongly absorbing grey slab in an otherwise uniform medium, with an arbitrary distribution of sources, leads to a method of accounting for the effect of the slab within the framework of the diffusion approximation. It is necessary to introduce a new parameter, the linear extrapolation distance at the surface of the slab in an anti-symmetrical neutron distribution.

Gamma Activities in Irradiated Beryllium Oxide

Description: The major long lived activity induced in irradiated Pechiney and Brush BeO specimens is due to Se-46 arising from scandium present to the extent of about 1 p.p.m. The Brush specimens showed additional activities due to Fe-59 and Co-60 and to Cr-51. The levels of Cr-51 found are considerably higher than would be expected on the basis of stated chromium impurity levels suggesting that the chromium is introduced during handling of the samples on site. Approximate values of the dose rate are includ… more
