ABSTRACT The morphology of the valve of Coscinodiscus wailesii and the development of its siliceous architecture, studied in the SEM and TEM, is compared with valve formation in Thalassiosira eccentrica (Ehrenberg.) Cleve. Though the areolae‐architecture of these two species differs in such that the cribrum is proxima…

Abstract A complete conversion series for mica/smectites was found in a hydrothermal alteration envelope around Kuroko-type ore deposits at the Shinzan area, Akita Prefecture, Northeast Japan. The minerals are an alteration product of volcanic glass of Miocene age and are commonly associated with zeolites and silica m…

This paper deals with a model of silicon oxidation including stress relaxation by viscous flow during growth. Based on a Deal–Grove process and a Maxwellian stress relaxation approach, an integrodifferential equation giving the inverse growth rate dt/deox vs eox is established. Valid in any case of thickness growth ra…

A transmission-line model for surface discharge and the analytical solution of the model have been presented previously. In this paper, an attempt is made to interpret the various properties of surface discharge with this model. The properties discussed are the discharge starting voltage vs the specific capacitance; t…

Abstract Sedimentologic zones that are differentiated by changes in lithology, mineralogy, chemical composition, and crystal morphology observable in scanning electron micrographs occur in Missouri high-alumina clay deposits. These properties and changes suggest that the high-alumina materials originated from Pennsylv…

We present a calculation of the dielectric function for a quasi-two-dimensional electron gas (Q2D) and compare our results with those obtained for two-dimensional (2D) and three-dimensional (3D) electron gases. We also compare our results to those obtained using the Thomas–Fermi approximation. We find that for a Q2D s…

Abstract Some of the dosimetric properties of a high sensitivity thermoluminescence dosemeter material, LiF(Mg,Cu,P), are described. This material, prepared at the Chinese Academy of Medical Sciences, has about 23 times higher sensitivity than that of LiF(Mg,Ti). It is stable and reusable without significant loss of s…

Abstract An interpretation is given of the broadened EPR spectra of Gd 3+ ions, which are frequently observed in polycrystalline ceramics and glasses. A reasonable simulation of the spectra is obtained, when these are regarded as a superposition of a large number of normal EPR powder spectra, each of which can be desc…

SUMMARY Progressive graphitization is measured from X‐ray patterns by the probability P for finding a carbon layer pair reaching the graphite order in the solid. TEM studies show that all carbons (whether graphitizing or not) contain small basic structural units less than 10 Å both in thickness and in diameter which a…
