How Hitler Controlled the Press
Adolf Hitler advocated total control of the press for many years before he was elected Führer. Almost immediately after he assumed power in 1932, Hitler began writing new laws and regulations that totally exorcised all freedoms from the German press. This study follows the path that Hitler took to control the German press from 1920 until the end of World War II. It utilized translations of documents and statements by men whom Hitler appointed to control the press and books written by experts in the fields of communications as well as men who prosecuted Nazi war criminals after World War II. The study found that the control of the press was indeed a very necessary ingredient in Hitler's climb to power and remained crucial during his reign as Führer.

Microprocessor-controlled scanning densitometer system
An Automated Scanning Densitometer System has been developed by uniting a microprocessor with a low energy x-ray densitometer system. The microprocessor controls the detector movement, provides self-calibration, compensates raw readings to provide time-linear output, controls both data storage and the host computer interface, and provides measurement output in engineering units for immediate reading. The densitometer, when used in a scanning mode, is a precision reference instrument that provides chordal average density measurements over the cross section of a pipe under steady-state flow conditions. Results have shown an improvement over the original densitometer in reliability and repeatability of the system, an a factor-of-five improvement in accuracy.

Automated controlled-potential coulometer for plutonium determination
The automated controlled-potential coulometer for the determination of plutonium described in this report is the second in a series of automated instruments designed to determine plutonium and uranium contents in nuclear fuel cycle materials. The measurement precision of the instrument is 0.1% relative standard deviation at the 5-mg plutonium level. A highly selective method of analysis was developed, involving reduction of plutonium to Pu(III) in a 5.5 M hydrochloric acid-0.015 M sulfamic acid electrolyte; oxidation of diverse ions, but not Pu(III); addition of phosphate complexant to reduce the Pu(III)-Pu(IV) potential; and oxidation of Pu(III) to Pu(IV) as the measurement step. Construction details of the mechanical and electrical systems of the instrument and control-system software are described, along with instrument preoperational adjustments and tests and sample analysis operations.

Cue-Controlled Relaxation: Saving Time Versus Efficacy
Cue-controlled relaxation is looked at to determine whether a component is efficacious as the entire procedure. Subjects were 40 male and 40 female undergraduates. Subjects were randomly assigned to one of four conditions: cue-controlled relaxation, progressive muscle relaxation, breathing exercises with a paired. cue word, on a presentation of the cue word without being paired. It was hypothesized that cue-controlled relaxation would be superior to a component of cue-controlled relaxation. It was determined that cue-controlled relaxation is not more efficacious than a particular component. Data suggests the majority of anxiety reduction takes place when the treatment focuses on the same modality from which the subject receives the most information about their anxiety. Implications and suggestions for further research are presented.

Controlled-source audiomagnetotellurics in geothermal exploration. Topical report
Theoretical and field tests indicate that the controlled-source audiomagnetotelluric (CSAMT) method provides an efficient means of delineating the shallow resistivity pattern above a hydrothermal system. Utilizing a transmitter overcomes the main limitation of conventional AMT: variable and unreliable natural source fields. Reliable CSAMT measurements can be made with a simple scalar receiver. Calculations for a half-space show that the plane wave assumption is valid when the transmitter is more than 3 skin depths away in the broadside configuration and more than 5 skin depths away in the collinear configuration. Three dimensional numerical modeling results for a bipole source 5 skin depths away compare well with those for a plane wave source, showing that the method is valid. Comparisons between 2D and 3D model results show that a 2D MT program can be used to interpret CSAMT data. A CMAST survey at the Roosevelt Hot Springs KGRA produced apparent resistivity contour maps at four frequecies: 32, 98, 977, and 5208 Hz. These maps show the same features as a first-separation dipole-dipole resistivity map. Detailed CSAMT data was also collected at 10 frequencies on two profiles. Two-dimensional MT modeling (TM mode) of the resulting pseudosections yields models similar to those derived by …

Design and evaluation of a microcomputer-controlled remote pipetter system
A remote pipetter has been designed and evaluated. The system is suitable for use in either a hot-cell or a glove-box environment and, therefore, is applicable in any situation where operating personnel must be separated from hazardous materials. The principle of operation for the pipetter is the displacement of liquid via a calibrated, screw-driven plunger. Variably sized aliquots of 1 to 1000 ..mu..L can be delivered. A steppng motor is used to move the plunger, and its position is verified with a linear variable differential transformer. The unit is controlled by a microcomputer. Besides the required operation sequences and error checking, a self-calibration check has been designed into the software. Measured accuracies and precisions of aliquot delivery are 0.4 and 0.2%, respectively.

Controlled-air incineration of alpha-bearing solid wastes
The Los Alamos Scientific Laboratory is completing a study of controlled-air incineration (CAI) as a technique for volume reduction and stabilization of combustible transuranic-contaminated solid wastes. To demonstrate feasibility, a process has been assembled and operated on synthetic and contaminated combustibles. This paper summarizes the CAI project history, process design, provisions for radioactive operation, experimental results to date, and future plans. Achievements include operation at the design feed rate as well as combustion of separate feed compositions including cellulosics, polyethylene, polyvinyl chloride (PVC) and latex rubber. Refractory life has been satisfactory to date, with studies continuing. The offgas cleanup system has proven to be extremely effective; the final high-efficiency filters showing virtually no pressure drop increase. The ability of the system to process high concentrations of PVC has been demonstrated with no chloride-induced degradation detected. Chloride and sulfate removal from the offgas has been excellent with concentrations reaching 8 and 10 ppM maximum, respectively, in the process condensate.

Computer-controlled on-line gamma analysis for krypton-85
/sup 85/Kr will be evolved from spent nuclear fuel during both the voloxidation and dissolution processes, so a reliable method for on-line analysis of /sup 85/Kr in the off-gas system is needed. Tritium, /sup 14/C, and /sup 129/I were trapped, and the activity of /sup 85/Kr was then measured using a Li-drifted Ge detector. Equipment used to carry out this analysis is described; the PET computer is used. The /sup 85/Kr evolution rate was correlated with the fuel dissolution rate; the close correlation permits one to monitor the fuel dissolution process. 11 figures. (DLC)

A computer-controlled automated test system for fatigue and fracture testing
A computer-controlled system consisting of a servohydraulic test machine, an in-house designed test controller, and a desktop computer has been developed for performing automated fracture toughness and fatigue crack growth testing both in the laboratory and in hot cells for remote testing of irradiated specimens. Both unloading compliance and dc-potential drop can be used to monitor crack growth. The test controller includes a dc-current supply programmer, a function generator for driving the servohydraulic test machine to required test outputs, five measurement channels (each consisting of low-pass filter, track/hold amplifier, and 16-bit analog-to-digital converter), and digital logic for various control and data multiplexing functions. The test controller connects to the computer via a 16-bit wide photo-isolated bidirectional bus. The computer, a Hewlett-Packard series 200/300, inputs specimen and test parameters from the operator, configures the test controller, stores test data from the test controller in memory, does preliminary analysis during the test, and records sensor calibrations, specimen and test parameters, and test data on flexible diskette for later recall and analysis with measured initial and final crack length information. During the test, the operator can change test parameters as necessary. 24 refs., 6 figs.

The Effectiveness of Skin Temperature Biofeedback with versus without Cue-Controlled Training
This study compared biofeedback assisted cue-controlled skin temperature training with skin temperature biofeedback training in subjects attempting to raise the digital skin temperature of their dominant hand. In addition to classification according to training, the subjects were also divided into two diagnostic groups. One group was composed of subjects with cold hands and Raynaud's disease while the other group consisted of nonRaynaud's disease cold handed subjects. The treatment and diagnostic groups were compared along the dimensions of amount of posttreatment digital skin temperature change and degree of generalization of digital skin temperature control to a cold room challenge task.

J-controlled crack growth as an indicator of hydrogen-stainless steel compatibility
The J-integral was evaluated as a parameter to characterize fracture of stainless steels and as a measure of hydrogen damage. C-shaped specimens of type 304L, 316, and 21-6-9 stainless steels were tested in high pressure helium and hydrogen. The critical force for crack initiation (Jm), and tearing resistance (dJ/da) were decreased by hydrogen in all three alloys. The J-integral appears useful as a measure of hydrogen compatibility because it is sensitive to both test environment and microstructure.

Portable, remotely operated, computer-controlled, quadrupole mass spectrometer for field use
A portable, remote-controlled mass spectrometer was required at the Nevada Test Site to analyze prompt post-event gas from the nuclear cavity in support of the underground testing program. A Balzers QMG-511 quadrupole was chosen for its ability to be interfaced to a DEC LSI-11 computer and to withstand the ground movement caused by this field environment. The inlet system valves, the pumps, the pressure and temperature transducers, and the quadrupole mass spectrometer are controlled by a read-only-memory-based DEC LSI-11/2 with a high-speed microwave link to the control point which is typically 30 miles away. The computer at the control point is a DEC LSI-11/23 running the RSX-11 operating system. The instrument was automated as much as possible because the system is run by inexperienced operators at times. The mass spectrometer has been used on an initial field event with excellent performance. The gas analysis system is described, including automation by a novel computer control method which reduces operator errors and allows dynamic access to the system parameters.

Los Alamos Controlled Air Incinerator for hazardous chemical and mixed radioactive wastes
The Los Alamos Controlled Air Incinerator (CAI) is currently the only radioactive waste incineration facility in the US permitted to treat polychlorinated biphenyls (PCBs). The CAI was developed in the mid-1970's as a demonstration system for volume reduction of transuranic (TRU) contaminated combustible solid wastes. It has since undergone additions and modifications to accommodate hazardous chemical wastes in response to a need within the Department of Energy (DOE) to treat mixed radioactive/chemical wastes. An overview of these additions which include a liquid feed system, a high intensity liquid injection burner, and an activated carbon adsorption unit is presented here. Also included is a discussion of the procedures required for Toxic Substances Control Act (TSCA) and Resource Conservation and Recovery Act (RCRA) permitting of the CAI.

Remote controlled underground mining system preliminary design and concept plans. Final report
The proposed mining technique has the potential to mine coal from underground horizontal or pitching seams in the 9-foot thickness range at an estimated cost ranging from $7.987 to $10.152 per ton. The estimate is established on conclusions drawn from: (1) the anticipated mining rate, in terms of tons per hour, that the mining system's hardware is expected to achieve as an average; (2) the approximate cost of the mining hardware amortized on a production service life expectancy of 4,000,000 tons; (3) logistics pertinent to continuous mine production, requiring the operation of two Mining Rigs simultaneously with operating crews totaling to 9 men per shift; (4) the angle of the mine bores into pitching seams extend, whenever possible, to no more than 30/sup 0/ from the horizontal; (5) mine bores extend to maximum feasible or permissible length. A bore length of 2500 feet is considered feasible; and (6) gas recovery from the mine bores can be accomplished with relative ease. The value of this, however, has not been determined since its handling as a recoverable requires investigation on hardware assemblies necessary to its processing, and the volume that must exist to invite a commercially attractive effort.
