Metabolism of C¹⁴-Carboxyl-Labeled-3-Hydroxyanthranilic Acid in Normal and Neoplastic Mice

Description: The o-aminophenol, 3-hydroxyanthranilic acid (3-OHAA) is a metabolite of tryptophan normally present in urine in trace quantities. C14-3-OHAA was given to normal mice and mice with either mammary adenocarcinoma, glioblastoma multiforme or ascites tumor to study the influence of these transplantable tumors on metabolism of 3-OHAA.

Spectrophotometric Titration of Milligram Quantities of Barium

Description: Manns et al have published a titrimetric method for barium in which 500 mg of barium acetate were titrated with 0.1 M Versene solution (disodium dihydrogen ethylenediaminatetetraacedic acid). The concentration of dye used by these investigators was such that under tungsten illumination a color change from wine-red to almost colorless was observed at the end-point. The application of this procedure by others to smaller amounts of barium has indicated the use of more dilute titrant and additional… more

The Nuclear Reactor with a Transverse Air Gap

Description: Diffusion theory and transport theory approaches to the problem of a nuclear reactor with a transverse air gap are compared. It is suggested that the differences in results for thin gaps is due to the fact that diffusion theory does not adequately represent the flux distribution in the immediate vicinity of the gap. For mathematical conveniences previous treatments of the gap problem have made use of fictitious image piles which exaggerate the neutron losses. The extent of the error is estimate… more

The Radiation Chemistry of Nitrite Ion in Aqueous Solution

Description: When deaerated solutions of KNO2 at their natural pH are irradiated with γ- or x-rays, the main initial reaction is a formation of hydrogen and hydrogen peroxide. As peroxide builds up, a radiation-induced reaction between nitrite and peroxide sets in, which results in the formation of nitrate. This reaction is slower the higher the nitrite concentration. The kinetics of the nitrite-peroxide reaction were studied in detail by the irradiation of synthetic mixtures, and the results were satisfact… more

Pile Neutron Effects on Coenzyme I Levels in Rat Livers

Description: The majority of radiation experiments conducted with enzyme systems has been done with x-rays and gamma rays. The experiments reported here were carried out to determine what influence the fast and slow neutrons from a nuclear reactor (atomic pile) have on coenzyme level in the livers of rats.

Occurrence of Technetium-98 in Nature

Description: The non-existence of technetium in nature, long considered a fact of axiomatic validity, has become subject to considerable doubt in recent years due to the discovery of technetium in the sun and in S-type stars.

Analytic Spin Functions of a Single Variable

Description: There has been considerable recent interest in the development of spin representations which are operations upon analytical functions. The familiar Pauli spin matrix representation, has been sufficient for the solutions of most problems involving nonrelativistic electron spin, but it is to be hoped that, for some problems, an "analytic" representation could be found which has greater physical significance. The new representations that have been presented all hae spin functions of two or more va… more

Radioactive Anthracene-C14 and Acridine-C14 from the Neutron Irradiation of Acridine

Description: Anthracene-C14 has been produced by neutron irradiation of the nitrogen homolog, acridine. The recoiling carbon 14 entities produced by the N14(n,p)C14 reaction were also found in acridine molecules, where the nitrogen had not undergone neutron capture during the course of irradiation. The ratio of activity as acridine to the activity as anthracene was about 19/1. Of the total activity produced in the samples, 3.5% was found as acridine, and 0.2% was found as anthracene.

The Experimental Application of Neutron Capture Therapy to Glioblastoma Multiforme

Description: The rapid development of the field of atomic energy during the past few years now permits the exploration of applications to medicine involving new concepts in the treatment of cancer. One such has been the study of neutron capture therapy which is being developed at the Brookhaven National Laboratory.

The Mass Spectrum of Lithium Iodide

Description: The mass spectrum of lithium iodide vapor produced from salt heated in an oven in the ion source of an analytical mass spectrometer was investigated as a function of oven temperature. Evidence was obtained for the existence in the vapor of both monomer and dimer. Partial heats of sublimation to monomer and dimer at 0°K were found to be 44.5 ± 7 and 45.0 ± 2 kcal respectively. The heat of dissociation of (LiI)2 into gaseous monomers was found to be 44.0 ± 2.2 kcal. The partial heat of sublimatio… more

Radiation Damage to Water

Description: Water may decompose under radiation to give hydrogen and oxygen gases and small amounts of hydrogen peroxide. The amount of decomposition depends critically on the nature of the radiation, the kind and amount of dissolved materials present, and the temperature. Destruction of dissolved material may proceed to a greater extent than that of the water itself. The basic theory of these effects is briefly outlined. Engineering problems resulting from radiation chemical effects in water are discussed… more

Paper for Glasgow Conference on Nuclear Physics: Cosmotron Results on Pion-Nucleon Interactions

Description: A considerable number of experiments have been performed at the Cosmotron which deal with the interactions between pions and nucleons. Some of these are concerned with the scattering of pions by nucleons, and some with the production of pions in nucleon-nucleon collisions. I will try to give the general results on both pion scattering and pion production, but it will not be possible to describe many experimental details.

Abstract for the Glasgow Meeting - "International Conference on Nuclear Physics": Gamma Transitions and the Shell Model

Description: The study of the interaction of the electromagnetic field with nuclei has proved very fruitful for the elucidation of many details of nuclear structure. The γ-ray transitions observed in either absorption or emission can be divided into three classes, depending on whether the matrix elements of the transition are (1) much larger, (2) approximately equal or (3) much smaller than those expected for single proton transitions which are usually taken as a norm. In class (1) we find (a) the broad tra… more

Effects of Ionizing Radiation on Seeds of Barley

Description: For some time we have been interested in the influence of radiation with different specific ionizations on the relation of the production of genetic changes to survival and seedling injury in irradiated seeds of barley. Our studies have shown that barley seeds subjected to any given dose of thermal neutrons or fast neutrons are much more uniformly affected than seeds treated with any given dose of x-rays or 2 Mev electrons. In addition, it has been demonstrated that when dormant seeds of barley… more

The Relation of Genome Number to Radiosensitivity in Habrobracon

Description: The problem of finding the site of injury from x-radiation is usually resolved to whether the nucleus or the cytoplasm is more radiosensitive. This is not easily determined sines the various cell components are interdependent and therefore cannot be evaluated separately. One approach to this problem is to compare the radiosensitivity of individuals that differ in the number of sets of chromosomes. Thus, by comparing haploids, diploids and polyploids one can determine whether additional genomes … more

Polarographic Determination of Zirconium

Description: In aqeuous solution hydrogen interferes with the discharge of zirconium. Cozzi added methylene blue to effect a separation of potential; however, only a small part of the zirconium participates in the electrode reaction and the wave is poorly defined. Colichman and Ludewig carried out the polarography in anhydrous methanol and thus avoided interference due to hydrogen ions. It has been found that a polarographic determination of zirconium can be carried out in aqueous solution if the zirconium … more

Bacterial Virus: Radiation and Function

Description: One of the materials most extensively studied with the dry state ionizing particle approach described in the preceding papers has been T-1 bacteriophage. It was one of the earliest materials subjected to cyclotron bombardment in the Yale biophysics group (Pollard and Forro, 1951) and a number of workers associated with the group have from time to time returned to it (Pollard and Jane Setlow, 1954). One reason is that investigation of various functional properties of a single material is relativ… more
