Test results from a uranium hadron calorimeter using wire chamber readout
(Elsevier, 1987-03-01)
A uranium gas sampling calorimeter has been tested with electrons and pions between 1 and 50 GeV. A comparative evaluation of the response and the resolution for proportional and streamer mode operation of the gas wire ...
The finite element response matrix method for the solution of the neutron transport equation
(Elsevier, 1986)
The finite element response matrix method has been applied to the solution of the neutron transport equation. This method has previously been applied to the neutron diffusion equation for coarse mesh reactor analysis with ...
Intraperitoneal delivery of monoclonal antibodies: Enhanced regional delivery advantage using intravenous unlabeled anti-mouse antibody
(Elsevier, 1987)
Radiolabeled monoclonal antibodies (MAb) delivered intraperitoneally expose cells in contact with peritoneal fluid to considerably higher levels of MAb than if the MAb dose were given intravenously. This regional delivery ...
Alpha-particle emission from contaminants in counter materials
(Elsevier, 1987-04-01)
Energy spectra of surface activities from thorium and uranium contaminants have been investigated for typical counter materials. Soft-tempered stainless steel with a rate of 1.2 +/- 0.1 [alpha]-particles emitted per 100 ...
Exciton Dynamics in thin wires
(Elsevier, 1987-12-01)
When are molecular wires thin enough to show one-dimensional exciton kinetics? What are the characteristics of one-dimensional kinetics? What applications are there? Cylindrical naphthalene wires (5-5000 nanometer radius) ...
Matrix representation of decay schemes
(Elsevier, 1986-01-15)
A matrix representation of the scheme of radioactive decay combines the compactness of a tabular form with the positional information of a graphical "decay scheme". The representation is particularly convenient for generation ...
Response of high resolution drift tubes to relativistic heavy ions
(Elsevier, 1985-11-15)
We report the results of various tests undertaken in a program to develop a drift tube hodoscope for a cosmic ray balloon experiment intended to search for extragalactic antimatter. Included are studies of mechanical ...
Routine synthesis of N-[11C-methyl]scopolamine by phosphite mediated reductive methylation with [11C]formaldehyde
(Elsevier, 1988)
A synthesis of [11C]scopolamine capable of clinical delivery of this agent in high specific activity is described. The precursor [11C]formaldehyde was produced by catalytic oxidation of [11C]CH3OH over metallic silver and ...
Simulations of one-dimensional and fractal luminescence kinetics
(Elsevier, 1988-02)
Exciton and electron-hole recombination reactions were simulated on one-dimensional and fractal networks. Particle distributions depend on dimensionality and electric fields. Geminate vs. non-geminate and pulsed vs. ...
Application of coded apertures in tomographic head scanning
(Elsevier, 1984-03-15)
A circular ring tomograph, designated SPRINT, is under development for single photon emission tomography of the human head. Most data to date have been gathered using a single rotating slit inside the detector ring to ...
