Cytochemistry of Delayed Radionecrosis of the Murine Spinal Cord
In the vast field of radiation pathology we find pathologists, anatomists, and even physiologists busily at work, but the radiobiologist is conspicuously absent, although, according to Zirkle (1959), this field is clearly within his domain. Perhaps it is wise to take this broad hint of the scientifically so well equipped radiobiologist and to stay clear from an area in which an incalculable array of variables makes clearcut experimentation a hopeless venture, a priori. Perhaps it would be better if the pathologist, who must study pertinent material, restricts himself humbly to the recording of his observations, refraining from any attempt at interpretation. On the other hand, since seemingly audacious speculation has borne fruit in the past and the value of the information that results, if the speculation proves to be correct, is worth many times the effort, there is obvious justification for a thesis on the mechanism of delayed radionecrosis.

Thin Film Measurements by X-Ray Emission Spectrography
When a beam of X-rays penetrates through a layer of material, the intensity of the beam is reduced by absorption. some of the energy that has been absorbed may be re-emitted as X-ray quanta, by the atoms that absorbed it, at a wavelength characteristic of the emitting atom but longer than the quantum absorbed. Four methods of measuring thin films that use X-ray emission apparatus have been described, each of which is useful over a limited range of thickness, and for certain kinds of samples.

The Quantitative Estimation of the Activity of Beta Particle Emitters

Physical and Chemical Properties of Particles
Electron microscopy is invaluable in determining the organization of the bacterial cell. In Fig. 1 we see an electron micrograph of a thin section of a single cell of Escherichia coli. There are three prominent regions: (1) the bacterial membrane, (2) the centrally located sparse region in which thin fibrils of DNA are located, and (3) the main body of the cell with densely packed particles. All the particles in the latter area are probably ribosomes. This paper will focus attention on the structure and function of ribosomes and nucleic acids directly involved in the protein synthesis in E. coli. In fig. 2 a cell segment containing ribosomes is compared with a purified preparation of 70 Svedberg (S) and 100S ribosomes at the same magnification. Most ribosomes in the bacterium are similar in size to the 70S ribosome: further work on this point is in progress.

The Effects of Non-Uniform Flow and Concentration Distributions and the Effect of the Local Relative Velocity on the Average Volumetric Concentration in Two-Phase Flow
Abstract: A general expression which can be used either for predicting the average volumetric concentration or for analyzing and interpreting experimental data is derived. The analysis takes into account both the effect of non-uniform flow and concentration profiles as well as the effect of the local relative velocity between phases. The first effect is taken into account by a distribution parameter, whereas the latter is accounted for by the weighted average drift velocity.

Survey of Component Requirements and Availability for Gas-Cooled Nuclear Reactor Power Plants
"Helium, nitrogen, carbon dioxide, and other gases suitable as reactor coolants were evaluated. It is shown that because of the helium conservation program, recently authorized by legislation, sufficient helium will become available for domestic power plants and for the requirements of the Euratom group. Tables of thermodynamic properties for helium and molecular nitrogen were computed from the Beattie-Bridgman equation of state. Specific enthalpy, specific entropy, isobaric specific heat, specific heat ratio, compressibility factor, specific volume, and acoustic velocity are tabulated over the range helium and molecular nitrogen are given."

Progress Report on Waste Processing Development Project
The work of the BNL Waste Processing Development Project has been concerned with developing means to accomplish three main objectives in handling radiochemical wastes. One is to reduce the corrosiveness of the waste. At present some wastes must be stored in SS vessels at high cost, since other tankage would not resist corrosion for any length of time. Hanford has solved a part of this problem by storing a neutralized or alkaline waste which can be contained more cheaply in 1020 steel vessels, although neutralization increases its total volume 50 percent over the original acid solution volume. Another aim in waste disposal is to reduce the mobility of the water. Although equipment is checked and double checked, and corrosion resistance is assured by extra thick-walled vessels, the possibility exists that a leak in such storage tanks may develop. At such times the solution may be carried by ground water into populated areas, whereas a relatively immobile waste would remain a local problem. A third and very important consideration is a desirable reduction in total waste volume. Since costs of waste storage are propositional to the volume stored, any reduction in total volume will reduce the total cost.

Effects of Insulin of Hepatic Glucose Metabolism and Glucose Utilization by Tissues
The mechanism whereby insulin lowers the blood glucose concentration is currently under extensive investigation. Despite the general agreement that the addition of insulin increases glucose uptake by various isolated tissues, the question has been raised whether administered insulin produces its blood sugar lowering effect in vivo primarily in increasing glucose uptake. Furthermore, it has been suggested that physiologically-released insulin may not exert the same effects as are produced by administered insulin. Attention has also been focused on whether insulin (exogenous or endogenous) exerts its action mainly or entirely on the liver and to what extent insulin influences glucose uptake and glucose production by the liver. The studies to be reported are a continuation of earlier work and are concerned with the effects of insulin, both exogenous and endogenous, on glucose utilization by the tissues and glucose production by the liver under various dietary condition in the unanethetized, intact dog, using C¹⁴ glucose.

On the Hormonal Regulation of Carbohydrate Metabolism; Studies with C14 Glucose
Earlier studies concerned with the influence of various hormones on carbohydrate metabolism in the dog were presented to this Conference in 1952. These studies dealt with the effects of adrenalectomy and hypophysectomy, and of regimens of anterior pituitary and adrenal hormones. Observations of changes in blood glucose concentration brought about by the administration of insulin, a glucose load, or of a epinephrine played a major part in this earlier work.

Hyperon-Nucleon Scattering
"The hyperon-nucleon scattering is calculated for LAMBDA laboratory energies to 315 Mev. The potentials used were those linear combinations of the nucleon-nucleon potentials as prescribed by global symmetry. The mass difference between the LAMBDA - and SIGMA -hyperon was taken into account in the kinematics. The mass differences between the SIGMA -hyperons and between the nucleons are neglected. Angular distributions and total cross sections are given for all the possible hyperon-nucleon scattering reactions."

The Calculation of Crystal and Counter Settings for the Collection of Crystallographic Data with a Counter-Diffractometer in the Equatorial Plane
Formulas are developed for the angle between any two vectors lying in a plane through the origin of reciprocal space. The application of these formulas for computing the counter and crystal angles for the collection of data with a counter-- diffractometer in the equatorial plane is developed, and a suitable computer program, written in FORTRAN without format suitable for an IBM 1620 computer, is described.

The Motion of a Charged Particle Near a Zero Field Point
"The behavior of charged particles in a plasma-free cusp field, or in a cusp field where there is very little plasma, is studied. The numerical computations described may provide a valid picture of the behavior of particles outside such a body of plasma or in the early stages of creation of such a cusped plasma in the low- beta limit. The computations provide a striking illustration of orbits which neither have constant magnetic moment nor behave so irregularly as to defy explanation."
