Book Description
An X-ray analysis of the molecular and crystal structure of 2-(4'-amino-5'-azamethenyl pyrimidyl)-3 pentene-4-ol was recently completed. Significant results of this work include the determination of the structural parameters of the pyrimidine ring with an accuracy hitherto unavailable in the chemical literature, and the elucidation of a comprehensive system of hydrogen bonds which, in large part, are responsible for the molecular packing as it exists in the crystal. Each molecule participates in a total of six hydrogen bonds. Two amino hydrogen atoms and one hydroxyl hydrogen atom participate in hydrogen bonds to other molecules and three nitrogen atoms (two in the ring and one in the long side-chain) participate in hydrogen bonds which have the hydrogen atom chemically bound to adjacent molecules.

Book Description
The propagation of electromagnetic waves in a horizontally stratified layer of gyrotropic medium is discussed. Derivation of a comprehensive representation for magneto-ionic coupling coefficients allows interpretation of the physical significance of the coupling. Introduction of an invariant quantity for an inhomogeneous medium becomes an important guide for numerical solutions of the wave equation. Numerical results of magneto-ionic coupling coefficients are presented. Based on region properties, characteristic wave types are defined: for the isotropic region, linearly polarized waves are used; for the anisotropic region, elliptically polarized waves generally are applied.

Book Description
The following paper represents work to date on the deformation method for quadratic programming and thus may be regarded as a sequel to Zahl, S. (1964) A Deformation Method for Quadratic Programming, Research Note AFCRL-63-132. It gives an explanation of a modified Iverson programming language and uses this to give a detailed algorithm for the Zahl Deformation Method of Quadratic Programming.

Book Description
Methods of obtaining the optical constants of a material from the analysis of the reflectivity spectrum are given. Both the Kramers-Kronig integral relations and the classical oscillator theory are discussed and applied to the infrared lattice vibration data of Mg2Sn and CaF2.

Book Description
The mapping of extended, cultural ground targets by an airborne radar is examined using communication theory concepts including those of the antenna transfer function and the target spatial frequency spectrum. Use of the set of transfer functions that correspond to Taylor aperture distributions and specification of the targets directly in terms of their spatial frequency spectra, permits one to examine the antenna images for quality and resolution. The results obtained indicate that resolution for a class of ground targets can be much better than is predicted by the two-point Rayleigh resolution criterion. It is also true that there can be situations in which the shape of the antenna images are quite independent of the radiation pattern. Several types of spatial noise were also included in the input spectrum to investigate noise effects on image quality and resolution. (Author).

Book Description
The results of an experimental study of zone refining of the binary system triphenyl antimony-biphenyl are presented. The isotope Sb124, which is a strong gamma emitter, was employed as a tracer; this allowed a rapid in situ nondestructive analysis, closely spaced experimental points, and the opportunity to study distribution as a function of varying experimental conditions. With the aid of computers (IBM 7090 and IBM 7044) apparent (distribution coefficients) were calculated and the experimental data compared with those predicted from various mathematical models.
