Paramagnetic Suseptibilities and Electronic Structure of AqueousCations of Elements 92 to 95

Description: Magnetic susceptibilities per gram atomic weight of elements 92 to 95 in most of their oxidation states were measured on 0.1 ml of solution which was 0.007 to 0.09 M in heavy element. The values obtained (all paramagnetic) in c.g.s. units x 10{sup 6} were: U(IV), 3690; Np(VI), 2060; Np(V), 4120; Np(IV), 4000; Pu(IV), 1610; Pu(III), 370; Am(III), 720. The results could be interpreted only on the basis of electronic configurations 5f{sup n}, even though susceptibilities were generally lower than … more

N-17, A Delayed Neutron Emitter

Description: The decay scheme of a 4.2 second neutron emitter has been investigated in detail. Chemical and physical evidence shows that it is N{sup 17}, which emits beta rays to a broad excited state of O{sup 17}, which then breaks up into a neutron plus O{sup 16}. The energy spectrum of the neutrons is determined by measuring the energies of the O{sup 16} recoils in a proportional counter. The neutrons have a most probable energy of 0.9 Mev, a 'half width' of less than .5 Mev, and an upper limit of about … more

Biology Seminar : methods of assaying for plutonium in biological materials

Description: From introduction: "Since plutonium is manufactured at the Hanford Works, a study of its effect on biological materials is important. To determine the amount of plutonium deposited in a biological sample, it is necessary to have an accurate method for extracting plutonium from these samples. Some of the different methods for plutonium assay are reviewed and given in this paper."

Friction Coefficients in the Inlet Length of Smooth Round Tubes

Description: Note presenting an experimental study of friction coefficients near the inlet of smooth, round tubes with bellmouth entrances. Four different combinations of approach section and bellmouth entry were used. Results regarding the apparent local friction coefficient, integrated friction coefficient, effect of induced turbulence, laminar inlet zone, developed friction coefficient, and application to discharge coefficients for rounded-entrance flow nozzles are provided.

Analysis for C{sup 14} and S{sup 35} in urine

Description: On June 1, 1948, a fire in the neoprene seal at 100-F Area potentially exposed nine to radioactive. An overnight collection of urine was made from these men and the samples submitted, along with a piece of neoprene seal, to the H.I. Development Laboratory for analysis. It is the purpose of this report to present the results of our investigation as to the type of contamination from the burning neoprene and the amount of contamination found in the urine sample.

Methods of assaying for plutonium in biological materials

Description: Since plutonium is manufactured at the Hanford Works in the 1940s, a study of its effect on biological materials is important. To determine the amount of plutonium deposited in a biological sample, it is necessary to have and accurate method for extracting plutonium from these samples. Some of the different methods for plutonium assay are reviewed and given in this paper dated November 16, 1948.

Analysis of urine samples for iron and S{sup 35}

Description: On August 21, 1948, several smear samples of contamination from the inner rod room at 100-F Area were submitted for beta identification. This contamination was spread as a result of maintenance work on the horizontal rods. Urine sample were deemed advisable for two men who had been exposed while working on the rods. These urine samples were also submitted for beta analyses. The analyses of the smears showed the contamination to consist of primarily S{sup 35} (65%) and Fe{sup 59} (30%)and minor … more

Charts of Compressibility Factors and Charts Showing Quantities Delivered by Commercial Cylinders for Hydrogen, Nitrogen, and Oxygen

Description: Two charts are given for each of the gases hydrogen, nitrogen, and oxygen. The first gives directly the number of standard cubic feet of the gas which a cylinder will deliver. The second chart gives values of the compressibility factor and of the density.

Electronics progress report

Description: The work to determine the feasibility of a pratical solution counter for alphas has been continued through this month. It has developed that the electronic technique using an Amperex mica-window GM tube (1.4 mg./cm{sup 2} mica) is reliable, and it now appears that the problem is mainly one of solution-mounting technique. Two four-input gamma mixers and three two-input B-wall mixers have been given a final check and assembled in cabinets with their associated scalers. These scalars, Instrument D… more

Stability derivatives of thin rectangular wings at supersonic speeds: Wing diagonals ahead of tip mach lines

Description: Report presenting theoretical results for the surface-velocity-potential functions, surface-pressure distributions, and stability derivatives for various motions at supersonic speeds of thin flat rectangular wings without dihedral. The investigation included steady and accelerating vertical and longitudinal motions and steady rolling, yawing, sideslipping, and pitching for Mach numbers are provided.

Two-dimensional compressible flow in conical mixed-flow compressors

Description: Report presenting a general method of analysis developed for the two-dimensional, steady, compressible flow through mixed-flow compressors in which the center line of the passage generates a right circular cone about the axis of the compressor. The two-dimensional, radial-discharge compressor is a special case in which the cone angle is equal to 180 degrees. The general analysis also applies to inward-flow turbines.

Exploratory wind-tunnel investigation of the effectiveness of area suction in eliminating leading-edge separation over an NACA 641A212 airfoil

Description: Report presenting an investigation in the two-dimensional low-turbulence pressure tunnel on an NACA 64(sub 1)A212 airfoil with various extents of permeable surface area between the leading edge and 12.5 percent chord to determine the effectiveness of area suction in eliminating leading-edge separation at high lift coefficients. The results indicated that not only was leading-edge separation prevented, but turbulent separation moving forward from the trailing edge was also delayed.

Calculation of Tunnel-Induced Upwash Velocities for Swept and Yawed Wings

Description: Report presenting a study of tunnel-induced upwash field for a point element of lift in a rectangular tunnel, which is shown to consist of three superimposed fields that, except for relative position, are independent of the lateral or longitudinal location of the lift element in the tunnel. A contour chart is given of the first field. For tunnels that are not rectangular, the corresponding procedure requires the preparation of a chart for each of several spanwise locations of the lifting elemen… more
