The Use of Radioactive Bromide and Chloride to Measure Extracellular Fluid

Description: During the last year we have been attempting to increase our understanding of the significance of the various dilution methods used to measure the extra-cellular fluid. When the dilution methods were first proposed to obtain a measure of the extracellular fluid volume, it was hoped that an agent could be found which would distribute uniformly and exclusively throughout this compartment, which would approach equilibrium rapidly, and which could be measured by simple and accurate procedures. We h… more

Accelerator Development Department Internal Report

Description: In this report we present solutions of the design problem in which a system of quadruple lenses is required to carry a particle beam from given focal lines in the x and y planes to other given focal lines. Particular attention will be given to the case of the anastigmatic lens system which takes a beam from one focal point to another focal point. Since the general problem is almost impossibly complicated a simplification is introduced by breaking the lens system into two parts. The first part o… more

The Deflecting Mode in the Circular Iris-Loaded Waveguide of a RF Particle Separator

Description: The rf particle separator, proposed in 1959 by W.K.H. Panofsky and now in preparation for the Brookhaven Alternating Gradient Synchrotron, required a rf structure which gives a transverse impulse to a passing relativistic particle. In order to produce an accumulative transverse deflection of a traveling charged particle with an electromagnetic field, it is necessary that the field contains a synchronous component and in principle, waveguides and cavities are equivalent with respect to the parti… more

Interactions of High Energy Antiprotons in Hydrogen

Description: In the fall of 1961 an extensive program of investigation of high energy p-p interactions was begun at the Brookhaven AGS. The BNL 20" liquid hydrogen bubble chamber and an electrostatically separated beam were used to obtain a total (to date) of 300,000 exposure with about 15 antiprotons per pulse. The exposures were made at antiproton momenta of 3.25 Bev/c and 3.69 Bev/c in the laboratory. Approximately 80% of the exposures were made 3.69 Bev/c antiprotons. A wide variety of reactions occur i… more

Some Problems in the Interpretation of Exponential Experiments

Description: Buckling measurements at BNL have employed two experimental methods which in principle should yield identical results but in practice show a systematic and significant discrepancy. In this paper the experimental evidence of these errors is reviewed and their source is traced by means of theory to the radial flux transients which perturb the asymptotic neutron spectrum in the exponential assemblies. Some alternate and apparently more precise methods of analyzing the data are examined theoretical… more

Adenosinetriphosphate Cleavage During the G-Actin to F-Actin Transformation and the Binding of Adenosinetriphosphate to F-Actin

Description: Since the discovery of the Straub and Feuer as well as Laki et al. that ATP bound to G-actin is transformed to ADP and inorganic phosphate during polymerization of actin (1, 2), it has become increasingly clear that the chemical changes in the nucleotide are related to the change in the physical state of the protein. Barany, Biro, Molnar and Straub have shown that highly purified actin preparation free of any enzyme which would use ATP, ADP or AMP as a substrate still catalyze the breakdown of … more

The Rearrangement of Diphenyl

Description: We wish to report unequivocal evidence for the water promoted, aluminum chloride induced intramolecular rearrangement of the benzene rings in diphenyl. When diphenyl 1→1,1'-C14, prepared in 80% yield via an Ullmann reaction on iodobenzene-1-C1 14, was heated to 100° for 30 min. with 10 mole % of aluminum chloride and 1 mole % of water, the radioactivity, originally localized at the two connecting carbons had been randomly distributed. Recovered active diphenyl was also shown to be randomized wh… more

The Simultaneous Labeling of Cells in Different Segments of the Mitotic Cycle with Tritiated Thymidine and Colchicine and the Effect of Colchicine on Thymidine Uptake

Description: Treatment of Pisum root meristems with nutrient solutions containing tritiated thymidine (H3-T) and colchicine simultaneously labeled cells in two different segments of the mitotic cycle. Tracings of the serial progression of these differently labeled cells through mitosis resembled sine-cosine curves. When the labeled cells are in interphase the sign of the curves is negative, when they are in mitosis the sign is positive. The concept of the mitotic cycle in terms of trigonometric functions wa… more

The Effect of Mitotic Cycle Duration on Chromosome Breakage in Meristematic Cells of Pisum Sativum

Description: One of the more apparent differences between acute and chronic irradiation is that exposure in the former is generally confined to a small fraction of a single mitotic cycle while in the latter; exposure of mitotically active tissue usually involves at least several cycles. Because of this difference, the number of cells in each stage of interphase would be of primary importance in acute radiation experiments since radiosensitivity is not the same in the G1, S and G2 periods. The duration of th… more

A Proposed Mechanism and Method of Correlation for Convective Boiling Heat Transfer with Liquid Metals

Description: An additive, interacting mechanism of micro and macro-convective heat transfer is proposed to represent boiling heat transfer with net vapor generation to saturated liquid metals in convective flow. Based on this mechanism, a method for calculating boiling coefficients is developed. The correlating is shown to be in fair agreement with early experimental results for convective boiling of potassium and sodium.

Effects of Chronic Excess Salt Ingestion: Possible Implications of the Accelerated Induction of Experimental Hypertension by 2,4-Dinitrophenol

Description: Recently, we reported that the administration of the thyroid hormone, L-triiodothyronine (T3), markedly accelerated the development of experimental hypertension associated with a high-salt intake in intact rate. Earlier, Selye and his associates and Masson, Corcoran, and Page has observed a similar effect from thyroxin in uninephrectomized salt-fed rats. We were aware of the fact that oxidative phosphorylation is uncoupled by the thyroid hormone and were intrigued by the possibility that such u… more

Neutron Diffraction Studies at the Puerto Rico Nuclear Center

Description: A neutron diffraction program was initiated recently at the Puerto Rico Nuclear Center. The two double crystal spectrometers in use were assembled with the aid of staff members of the Brookhaven National Laboratory. The first research problem to be completed was a single crystal structure analysis of CaWO4. Choosing the origin at the 4(a) tungsten site in the tetragonal I41/a cell. the 16(f) oxygen parameters were found to be as follows: x=0.2413 ± 0.0005, y=0.1511 ± 0.0006, z=0.0861 ± 0.0001.… more

On the Generation of an Arbitrarily Autocorrelated Sequence of Random Variables from a Sequence of Independent Random Numbers

Description: For a wide range of statistical experiments, we require a sequence of random variables [unintelligible], which have prescribed mean values μn and variances σn2, with a given autocorrelation ρt. The [unintelligible] are to be generated as a sequence of real functions of independent random numbers [unintelligible], each of which is uniformly distributed in. The reason for this choice of specification for the [unintelligible] is that most computers have standard subroutines which generate such uni… more

Preparation and Some Properties of Krypton Difluoride

Description: The compound KrF4 was prepared by Grosse et al. by passing an electric discharge through the elements at -196°C. Evidence for formation of KrF2 has been obtained by Pimental and Turner by UV irradiation of the elements frozen into an inert gas matrix at 20°K. Using an electron beam to irradiate krypton and fluorine at -150°C, we have prepared KrF2 in 100mg amounts and examined some of its properties.

Gene Structure: Genetic Fine Structure. Remarks.

Description: Though only recently established, this concept has been developing for a long time. More than thirty years ago Dubinin, Serebrovsky, and other, investigating the phenotypes of a number of "achaete-scute" alleles of Drosophilia melanogaster, found that the alleles could be arranged in a definite series accoding to bristle patters, and also that the heterozygotes lacked only those bristles which were affected in common by both participating alleles. They concluded that the serial classification o… more

An Investigation of the Low Frequency Motions in Isotactic and Atactic Polypropylene by Neutron Inelastic Scattering

Description: The vibrational spectra between 1000 and 30 cm-1, derived from measurements of the inelastic scattering of "cold" neutrons, are presented for isotactic polypropylene at samples temperatures below and above both the glass transition and the melting point. A tentative assignment of the observed modes is suggested by comparison with recent calculations by Miyazawa, Ideguchi, and Fukushima of the optically active phases of the fundamental vibrations for an isotactic helical polypropylene chain and … more

Rare Gas Isotope Contents in Mineral Fractions of the Indarch Meteorite

Description: We have measured the rare gas isotopes in mineral concentrates of the Indarch meteorite. We obtained samples from C. Frondel, who crushed some of the meteorite into small particles mainly in the 44 to 88 micron size. He fractionated the minerals into groups according to specific gravity, using heavy liquids and magnetic techniques. The fraction with specific gravity less than 2.4 is approximately 95% tridymite and represents about 1% of the whole stone. The fraction with specific gravity betwee… more
