Iron was deposited at room temperature in ultra-high vacuum (5 × 10−8 Torr) onto single-crystal films of copper oriented with (001) parallel to their plane. A shutter was moved between source and substrate so that iron deposits in which there were thickness gradients were obtained. Transmission electron micrographs an…

Single suspension insulator units of several types as well as multi-unit strings were studied in a large refrigerated chamber. Rime ice of various densities was deposited on these insulators. The increase of leakage currents, the reduction of flashover voltages, and the alteration of voltage distributions along insula…
Cells in a -wild population of a species belonging to the diatom germs Mastogloia may form frustules of 2 strikingly different morphologic types during their vegetative life cycle. Total conversion from coarsely structured morphologic form to a more finely structured form takes place during a single division; hence no…
The antiferromagnetic structure of Mn 5 Si 3 at low temperatures (Néel point 68 °K) has been determined by neutron diffraction using single crystals. The magnetic structure is complicated, and the model proposed consists of a modulated non-collinear spin structure propagated through the crystal in three hexagonally re…

In the orthorhombic modification of TeO 2 (tellurite) each tellurium atom is surrounded by four oxygen atoms at an average distance of 2.0 Å, similar to the tetragonal TeO 2 (paratellurite). The coordination polyhedron is a slightly distorted trigonal dipyramid, with both axial positions and only two of the three equa…

Phase relations were studied in the system ZrO 2 ‐MgO with emphasis on the range 1350° to 1600°C. A phase relation was determined from samples, using precision lattice parameters, X‐ray diffraction line intensities, and petrographic observations, and from dynamic observations of the phases present using high‐temperatu…
Abstract The stoichiometry, equilibrium, and kinetic properties of a terminal deoxynucleotidyltransferase isolated from calf thymus gland are described. The reaction catalyzed may be written dXTP + d(pY)m (Mg++)/→ d(pY)m(pX)n + nPPi and the ratio of polymer nucleotide to monomer at equilibrium (pH 7.0, 35°) is about 9…

The CO 2 Acceptor Gasification Process is discussed in light of the required properties of the CaO acceptor. Equilibrium data for reactions involving the CO 2 and sulfur acceptance and for sulfur rejection fit the process requirements. The kinetics of the reactions are also sufficiently rapid. Phase equilibrium data i…
The 0.1 M Na-pyrophosphate solution extracted some of the Fe-, Al-organic matter products in Podzol B and some Acid Brown Wooded B horizons, but it dissolved a low proportion of the free Fe in the B horizon of some Gleysolic soils. It did not dissolve the inorganic amorphous or crystalline Fe and Al substances tested.…
