A mathematical treatment of the dynamic behaviour of a power-transformer winding under axial short-circuit forces
The paper gives the mathematical formulation, and indicates the mathematical solution, of the problem of the dynamic behaviour of a transformer winding under axial short-circuit forces, certain basic physical assumptions being made initially. Various practical tapping arrangements are considered so that there may be e…
Studies of the Glass-formation Range of Silicate Systems
Following a previous report “Studies of the Glass-formation Range of Borate Systems” (This Journal, 69, 282 (1961)), we studied the glass-formation range of silicate systems. Although silicate glasses have long been used, sufficient systematic studies of the glassformation ranges of silicate systems have not yet been…

Reactions (p, 2pxn) sur le thorium 232 de 30 à 120 MeV
On a mesuré les sections efficaces de formation des isotopes 224, 225, 226, 227, 228 de l'actinium dans le thorium 232 bombardé par des protons de 30 à 120 MeV. Dans le domaine de basses énergies (30 à 80 MeV) la formation des Ac est attribuable aux processus (p, αxn) .
Coloration of Yttrium‐Doped CaF2 and SrF2 Crystals by X‐Ray Irradiation
Abstract CaF 2 and SrF 2 crystals are doped with trivalent yttrium ions, and X‐irradiated, which results in similar coloration spectra for both substances. The bands seem to satisfy MOLLWO 's relation v a 2 = const, since the SrF 2 bands are shifted to longer wavelengths compared with the corresponding CaF 2 bands. Th…
Anodic Film Growth by Anion Deposition in Aluminate, Tungstate, and Phosphate Solutions
Films were obtained by anodic treatment of Al, Mg, Ni, Fe, Zn, Bi, Cd, Co, and Cu in and Al, Bi, Cd, Cu, and Zn in . A formation voltage of 30v was applied for 10 min in all cases except Al in where the maximum formation voltage was 100v. The anodic films were studied by electron diffraction and chemical analyses. Fil…
Zur Deutung der Tieftemperatur‐Elektronenbestrahlung von Metallen
Abstract Bei Elektronenbestrahlung von Metallen interessiert der totale Wirkungsquerschnitt σ d ( E ) ( E Elektronenenergie) für Stöße, die zu einer bleibenden Verlagerung der von Elektronen getroffenen Atome (Primäratome) führen. σ d ( E ) wird experimentell aus Widerstandsmessungen bestimmt und kann theoretisch bere…
The Diffusion Coefficients for Hydrogen in β-Zirconium
The diffusion coefficients of hydrogen in β‐zirconium were calculated from experimental hydrogen sorption curves. The results were D ( cm 2 / sec ) = 5.32 × 10 − 3 exp ( − 8320 / RT ) , (760°–1010°C). This relationship was independent of hydrogen concentrations (to 41 a/o H) and oxygen concentrations (to 4.2 a/o O) in…
Magnetic Structure of the Mn5Ge3 Alloy
Abstract Neutron powder diffraction patterns are measured at 50°C and liquid nitrogen temperature. The crystal structure is defined as D8 8 (space group P6 3 /mcm), in agreement with CASTELLIZ 's data [2]. It is found that the atoms in the 4 (d) and 6 (g) positions have magnetic moments of (3 ± 0.1) and (2 ± 0.1) Bohr…
Melting Relations of CaO‐Manganese Oxide and MgO‐Manganese Oxide Mixtures in Air
Melting relations in the systems CaO‐manganese oxide and MgO‐manganese oxide in air have been determined at temperatures up to 1705°C. In the system CaO‐manganese oxide four crystalline phases have stable existence in equilibrium with liquids: lime (approximate composition CaO‐MnO), spinel (approximate composition Mn…
Accelerative effects in radiation-induced graft polymerization
It has been demonstrated that the use of solvent additives can substantially increase the rate of radiation-induced graft polymerization in the systems polyethylene–styrene, polypropylene–styrene, polyvinyl chloride–styrene, nylon–styrene, polyethylenemethyl acrylate, polypropylene–methyl acrylate, nylon–methyl acryla…
Mean Free Path of Hot Electrons and Holes in Metals
The mean free paths and attenuation lengths of hot electrons and holes in metals are calculated by Morte Cario methods. The results are compared with experimental results for electrons in Au,-Ag, Cu, and Pd and holes in Au. (T.F.H.)

Infrared Studies of Saline Sulfate Minerals
The cations Na, K, NH4, Ca, Mg, Mn, and, in certain instances, Ba, Sr, and Pb combine with the anion SO4 to form 58 mineral species. Slightly more than half are hydrous, and several contain Cl, F, or CO3. Infrared absorption spectra of most of the above sulfate s have been obtained with a split beam infrared spectroph…

The temperature dependence of the yield stress of polycrystalline iron
The values of the upper yield, the lower yield and the flow stresses of polycrystalline Armco iron are shown to have very similar dependences on temperature between 78°K and 200°K. The variation with temperature of the component of the upper and lower yield stresses which is associated with the unpinning of locked dis…
X-ray Study and Thermoelectric Properties of the W[sub x]Ta[sub 1−x]Se[sub 2] System
A wide range of compositions of the title system have been prepared with x ranging from 0.10 to 0.99, and x‐ray parameters and pertinent thermoelectric properties such as Seebeck coefficient, electrical resistivity, and thermal conductivity were determined. Particular emphasis was given to the range of x from 0.95 to…
