Pure Substances

Since there appears to be no definite information as to the electrical properties of pure elemental substances which are not metals, an attempt has been made to provide the necessary data in the case of sulphur. This element was chosen as being capable of easy purification, and because it can exist in a variety of forms, from the comparison of the electrical behaviour of which some information was expected to be obtained. The experimental work was begun in 1886, and some preliminary results were published by one of the authors and Mr. J. A. Pollock in the ‘Philosophical Magazine’ for 1890.

Mechanical And Electrical Properties

This article illustrates the development and preliminary results of SELINE, a self-opening neural interface. The advantages of this innovative neural interface are: higher selectivity due to its three-dimensional structure and efficient anchorage system to the nervous tissue. The device is made of polyimide that is a lightweight, flexible and biocompatible polymer. The electrode has been microfabricated using lithographic techniques; electrical and mechanical tests have been performed to evaluate the integrity of the device. Successful results have been obtained in the development of the electrode with excellent mechanical and electrical properties.

A New Technique

ABSTRACTA new technique for growth of exactly two monolayers of CaF2 on Si(111) substrates is demonstrated. This technique takes advantage of the tendency of CaF2 to form thick islands at Si step edges on vicinal substrates once a two-monolayer thick wetting layer is deposited. A comparison of I-V characteristics for epitaxial CaF2 layers grown on on-axis versus off-axis substrates demonstrates the advantages of this technique. In addition, preliminary results for electron tunneling through the CaF2 structure is shown using the ballistic electron emission microscopy (BEEM) technique.

Bipolar Type

ABSTRACTElectrical and crystal properties of seeded lateral epitaxial Si are evaluated as a function of distance from seeding area with the aid of a micro-probe RHEED and MOSFET fabrication. the results indicate that the quality of a grown layer is as good as that of bulk Si Crystal for most of the epitaxial layer. However, at the SiO2 edge, electrial properties are somewhat poor due to the existence of dislocation and residual stress.Element devices useful for SO structures are fabricated. Electrical properties of MOSPET's with double active areas indicate that surface and bottomregions of the epitaxial layer are all of device worthy quality.Insulated control gate bipolar type transistors are proposed and some preliminary results are shown.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

AbstractThe records of sunspot number, sunspot areas and sunspot locations gathered over the centuries by various observatories are reanalysed with the aim of finding as yet undiscovered connections between the different parameters of the sunspot cycle and the butterfly diagram. Preliminary results of such interrelationships are presented.

Right Ascension

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.
