Abstract An approximate method is described for calculating electrostatic fields of rotational symmetry with arbitrary boundary conditions. The method is based on the computation of the surface charge density on the field forming electrodes. Successfully tested by well-known analytical solutions, the method is applied…

The optical properties of Dow Corning-704 and -705 diffusion-pump oils have been measured from 4→24.8 eV using an open-dish technique. These are the first liquids for which optical constants have been obtained above 11.8 eV. In the region above 10.6 eV, the real part of the dielectric constant is structureless. A coll…

Abstract Almandite, a natural garnet, orders antiferromagnetically at T N = 7.5°K. The spin structure has the magnetic symmetry Ia 3 d ′. The oxygen parameters are x = − 0.03398, y = 0.04935, z = 0.15284 at 300°K; they have practically the same values at 4.2°K.

Abstract The photolysis of 1‐( o ‐azidophenyl)‐1 H ‐indazole (IV) has been found to give a mix ture of 6‐dehydroindazolo[1,2‐ a ]benzolriazole (VI) and 2,2′‐di(1‐indazolyl)azobenzene (VII). On the other hand, 1‐( o ‐nilrophenyl)‐1 H ‐indazole (1) was reduced with triethyl phosphite, affording VI and dibenzo[ a,i ] ind…

A laboratory gas circulation pump has been built in which the pump driving force is obtained by the alternate decomposition and regeneration of vanadium dihydride (VH2). This cyclic action is accomplished by alternately heating and cooling the hydride system using hot (50°C) and cold (18°C) water. The particular pump…

Abstract Impact behavior can be predicted for rate‐dependent foams from constant rate of strain response. The response must be factorized into a rate‐dependent modulus function and a strain‐dependent function. In this way the rate‐dependent modulus can vary throughout the impact as the velocity of the impacting object…

Maleylation of about four groups per tetramer of NAD‐free glyceraldehyde‐3‐phosphate dehydrogenase or of enzyme. NAD 2 complex inactivates the enzyme. However, enzyme. NAD 4 complex is inactivated only by maleylation of about 24 groups per tetramer. This shows that the presence of two moles of the relatively loosely b…

Abstract Synthesis of the naturally occurring polyester, D ‐poly‐β‐hydroxybutyrate (PHB) was accomplished by using an optically active monomer. Polymerization of D ‐(+)‐β‐butyrolactone (β‐BL) of 73% optical purity with a catalyst system of Et 3 Al–H 2 O produced a polymer with a similar optical activity and essentiall…

Self‐radiation from α‐decay of 244 Cm causes lattice swelling, phase transformations, and loss of structure in several Cm compounds. In Cm oxides, the percentage swelling at saturation decreases with decreasing symmetry: Swelling in fluorite (fee) CmO 2 (∼0.3%) is approximately twice that in bee C ‐type Cm 2 O 3 ; mon…

The properties of a highly correlated electron gas are discussed in relation to the recent work of Brinkman and Rice and the concept of the spin polaron. Tentative extensions of the theory are proposed for an electron gas in a random field, and these are checked against the observed behaviour of doped semiconductors.…
