Physical Studies of Cell Division: Statistical Fluctuations; Effects Due to X-Radiation, Temperature, and Hydrostatic Pressure

Description: Thesis discussing "a technique for determining the generation times of individual yeast cells...the effect of x-radiation on the generation times of individual cells and their progeny..." and "attempts to synchronize cell division in a population of cells."

Particle Trajectories in Homogeneous Magnetic Field with Linear Time Dependence

Description: Abstract: "Formulas are derived for the trajectory of a charged particle in a magnetic field which is a linear function of time. Graphs of certain functions are presented, by means of which a trajectory with given initial position and velocity may be plotted."

Influence of Fluorine Substitution on the Properties of Metal Chelate Compounds

Description: From introduction: "This is the first of three articles dealing with the influence of fluorine substitution in the ligand on the properties of metal chelate compounds. Although the primary purpose of this project was to study the influence of fluorine substitution on the properties -- particularly light absorption -- of uranyl compounds, copper chelates were chosen for preliminary study as model substances, because they are easily prepared."

The Technology of Large Mercury-Pumped Vacuum Systems

Description: From Abstract: "This paper deals with the vacuum design considerations of large systems involving the application of 8-inch through 32-inch mercury diffusion pumps. The selection, rating, and optimization of pumps are discussed along with the closely allied problem of baffling the pumps. The materials of construction and methods of fabrication to avoid subsequent system contamination are dealt with in detail. System interlocking and its associated instrumentation are illustrated by referral to … more

Suggested Uses of Cycloidal-Trajectory Particle Spectrometers in Nuclear Research

Description: From abstract: "The motion of a charged particle in a region of crossed electric and magnetic fields is discussed... Possible applications of such a system to various problems in nuclear research are suggested and it is shown to be possible in principle to measure the kinetic energy, mass, and ionic charge of various nuclear-reaction products and to separate various short-lived products for rapid examination. Two different devices are proposed. The application of the technique to investigation … more

Gamma Rays from the Interaction of 14-Mev Neutrons with Beryllium

Description: Abstract: "The cross section for the Be-9(n, t')Li-7*-->Li-7 + Y(0.477 Mev) reaction has been measured in the vicinity of 14 Mev by detecting the gamma-rays at scattering angles from 30 to 150 degrees. A time-of-flight technique was used to distinguish the gamma-rays from the high neutron background. The cross section drops from 20 mb at 13.6 Mev to 10 mb at 14.1 Mev and then rises to 30 mb at 14.7 Mev."

Passage of Electrons Through Matter

Description: One of the oldest properties of electrons is their emission of x-rays (discrete and continuous spectra) when impinging on matter. Cloud-chamber tracks show light ionization, and considerable multiple scattering, except for fast electrons. Tracks are long and range indefinite.

The Cloverleaf Cyclotron Three Phase Radiofrequency System

Description: The geometry of the magnetic pole structure in the cloverleaf cyclotron suggests the use of three dees excited by three phase rf placed in the valleys out of the way of the beam. Experience with the model machines indicates that it is desirable to be able to vary the phase angles between the three dee voltages through 30 or 40 degrees and to be able to maintain them at any given value within plus or minus one degree. It is desirable, also, to be able to vary the phase angle independently of the… more

Code Listings for the Floss III - Compatible Programs Including Floss Type 3 and Type 12, Nomac, and Dash N

Description: FLOSS III is a third-generation version of a digital computer program which solves a one-dimensional difference representation of the momentum, energy, continuity, and state equations for turbulent, compressible gas flow in equivalent hydraulic channels. Extensive use of this program has been employed in the design and performance analyses of Pluto-type nuclear heat exchangers, and in the specific case of the Tory II-A test series, agreement was obtained to better than 5% for all experimentally… more

Laboratory Measurement of the Mass and Size of the Copper Atom

Description: An easy experiment for undergraduate students to measure the mass and diameter of a copper atom can be performed with inexpensive apparatus normally available any college physics laboratory. By measuring the density and by copperplating, one can obtain results which are accurate to better than 5%.
