Current-Carrying Capacity and Transition State of Superconducting Solenoids
Montgomery and Chandrasekhar and Hulm suggested models for predicting Im and Hm of high-field superconducting solenoids. Montgomery's model for predicting the degradation effect of superconducting solenoids leads to a unique coil quenching characteristics if geometrically similar solenoids are considered. Experiments do not verify these predicted results. Chandrasekhar and Hulm's model leads to one unique coil quenching characteristic for all solenoids with identical wire type and turn distance; coils with identical load factor should display identical values im and Hm. An analysis of the surface currents in an ideal superconducting infinitely long solenoid demonstrated possible forms of shielding currents. Experiments with Pb coils with and without NbZr and compensation agree with results expected from this analysis, but contradict Chandrasekhar and Hulm's model. Measurements of individual turn resistances show behavior of a soft superconductor solenoid in the intermediate state.

Mass Systematics Involving Low-Lying Excited States
Technical report. From Abstract : "A step phenomenon in the nuclidic mass excess surface associated with magic numbers N, Z = 8 and 20 is shown to exist, whereas only breaks occur at higher magic numbers. Excited states are included which reveals possible smooth trends within Shell-Model subshells."

Chemical Binding in the Water Molecule
From Introduction : "This analysis partitions the electron density and the electronic pair density of the molecule into components corresponding promoted atomic states, to quasiclassical coulombic interactions of these promoted states, and to interactions resulting from the sharing of electrons between atoms."

Mass Spectrometric Evidence for the Pyridoxal-Leucine Reaction Mechanism
From Abstract : "The mass spectrum of leucine-dn, prepared by the reaction of pyridoxal with excess leucine in D2O medium, has been established using the crucible source techniques. ... The reaction can be used for the selective α, β-deuteration of amino acids other than leucine.

Reinvestigation of the CC Stretching and CH3 Rocking Assignments In Isopropyl and tert-Butyl Halides
From report: "In a series of paper (1-3) Sheppard has analyzed the vibrational spectra of simple alkyl halides. During the course of an investigation of the spectra of similar alkyl thiocyanates certain anomalies appeared in the assignments of the CC stretching and methyl rocking vibrations in isopropyl and tert.-butyl halides."

High Purity Calcium
Technical report. From Introduction : "For more than a century, methods employed in preparing calcium were based largely on electrowinning and the most successful were based on [Sir Humphrey] Davy's process. ... In general, the metal was of adequate quality for the industrial applications of the time, and although by 1940 some strides had been made in the purification of calcium, interests in the better grades of the metal were limited essentially to experimental work of academic concern."

Electromotive Force of Transfer Systems Containing Membranes
Report describes a few experiments designed to test the analysis of some systems where chemical energy can be converted to electric energy. From Abstract: "If a chemocouple is defined as an isothermal closed circuit, composed of two or more homogeneous ionic aqueous phases separated by two or more barriers of different sets of ionic transport numbers, we find that a spontaneous electric current flows in the closed circuit."

The Sparker, a Divice to Overcome the Multipactor Difficulty in Starting the Oscillator of a Cycloton
"Evacuated electrical oscillating cavities frequently are found to exhibit a strong loading due to electron (or iron) multiplications, the so-called multipactor effect. This effect tends to prevent the buildup of dee voltage in cyclotrons. In conventional cyclotrons driven from external oscillators having their own resonant tank circuits the difficulties are usually slight, but in cyclotrons using a simple dee system as the tank circuit difficulties are encountered in getting the oscillator to break into full oscillation."
