Radiation of electromagnetic fields in uniaxially anisotropic media*

Jakob J. Stamnes、George C. Sherman1976-08-01Journal of the Optical Society of America

The angular spectrum of plane waves representation is obtained for the electromagnetic field radiated by a localized current source in a uniaxially anisotropic medium. The linear medium is homogeneous throughout all space. It may be absorbing and temporally dispersive but is not spatially dispersive. The conductivity…

Dipole Moments and the Smectic C Phase

John W. Goodby、G. W. Gray、D. G. McDonnell1976-08-01Molecular crystals and liquid crystals

Current theories of the smectic C phase depend primarily on the presence of dipole moments. However, certain mesogens have now been prepared which suggest that an alternative view relating to the origin of these tilted lamellar phases will have to be considered.

An electrostatic model for collagen fibrils. The interaction of reconstituted collagen with Ca++, Na+, and Cl−

Shu‐Tung Li、Elton P. Katz1976-08-01Biopolymers

Abstract A model for the electrostatic properties of hydrated collagen fibrils, based on the concept of a “penetrable” protein, has been evaluated through studies of collagen fibrils that had been chemically modified to change their electrostatic properties,. A value of 0.28 ± 0.07 ml/g was found for the intrafibrilla…

Raffinose Metabolism in Escherichia coli K12

Kurt Werner Schmid、Rüdiger Schmitt1976-08-01European Journal of Biochemistry

The utilization by Escherichia coli K12 of raffinose as sole carbon source depends on a new raffinose transport system, an invertase and an alpha-galactosidase specified by the Raf-plasmid D1021. The alpha-galactosidase was purified to homogeneity from a mutant strain with constitutive synthesis of the enzyme. alpha-G…

X-Ray Studies of Polyethylene under High Pressure

Munehisa Yasuniwa、Ryosuke Enoshita、Tetuo Takemura1976-08-01Japanese Journal of Applied Physics

The phase diagram, growth processes of extended-chain crystal and high pressure phase, and the temperature dependency of lattice parameter in polyethylene have been studied under high pressure up to 6000 kg/cm 2 using a new high pressure X-ray diffraction apparatus. The high pressure phase diagram obtained by micro-DT…

High-performance transistors with arsenic-implanted polysil emitters

J. Graul、A. Glasl、H. Murrmann1976-08-01IEEE Journal of Solid-State Circuits

Integrated high-frequency transistors (f/SUB T/>3 GHz) with an arsenic implanted polysil emitter have been investigated. The results are compared with data of bipolar transistors made with the conventional planar technique. It is shown that better emitter efficiency higher current carrying capability, and improved emi…

Some Studies on Tuft Weight Distribution in the Opening Room

Aditya Singh、K R Salhotra、N.S. Kambo1976-08-01Textile Research Journal

A complete individualization of cotton tufts produced in an opening room is not easy, and hence the tuft weight distribution can be largely influenced by the technique used for tuft separation. Various research workers have arrived at different types of tuft weight frequency distribution. The present study describes a…

Crystal Field Induced Spin Rotation Observed by Magnetization Study of Polycrystalline NdCo2

G. Dublon、M. Kroupp、M.P. Dariel 等 4 位作者1976-08-01physica status solidi (b)

Abstract Magnetization measurements of polycrystalline NdCo 2 are reported as a function of temperature (4.2 to 200 K) and magnetic field (0.2 to 26 koe). Anomalies in the temperature dependence of the magnetization are attributed to a [110] to [100] spin rotation around 40 K. Single‐ion crystal field calculations whi…

An Anomalous Behavior of the Longitudinal Magnetoresistance in Semimetals

Katsukuni Yoshida1976-08-01Journal of the Physical Society of Japan

An anomalous longitudinal magnetoresistance which decreases with increasing magnetic field in an appropriate specimen geometry has been investigated for semimetals. An intuitive explanation of this phenomenon is given in terms of geometry of inhomogeneous currents under the influence of a magnetic field. Experimental…

The ligand hyperfine interaction with rare earth ions. II. Calculation of the paramagnetic NMR shift

Bruce R. McGarvey1976-08-01The Journal of Chemical Physics

The isotropic and anisotropic 19F NMR shifts for Yb3+ doped into alkaline earth fluorides is calculated using a covalent model for the spin transfer. The good agreement between theory and experiment is strong evidence for the covalent model being the correct model in the case of Yb3+. The calculations reveal that the…

1. Desmosine and isodesmosine were separated by ion-exchange and paper chromatography, after acid hydrolysis of purified elastin from beef ligamentum nuchae. The fractions obtained by ion-exchange chromatography were clearly mixtures of related compounds. The desmosine fraction could be resolved into seven compounds a…
