We investigated the influence of insulin concentration within the insulin pump on the metabolic and plasma free-insulin changes induced by a 6-h nocturnal interruption of continuous subcutaneous insulin infusion (CSII) in five C-peptide-negative insulin-dependent diabetic patients with low circulating levels of anti-insulin antibodies. We compared the changes in blood glucose, plasma free fatty acids, 3-hydroxybutyrate, and free insulin during the interruption from 2300 to 0500 h of the Nordisk Infuser loaded with either U-100 or U-20 regular insulin. The decrease in plasma free-insulin levels was slower, resulting in a significantly delayed and smaller increase in blood glucose levels (2.4 +/- 1.6 vs. 7.6 +/- 2.9 mM, P less than .025) when the pump contained U-100 instead of U-20 insulin. Although the increases in levels of plasma free fatty acids were similar in both tests, the rise in plasma 3-hydroxybutyrate levels tended to be reduced with U-100 insulin (414 +/- 139 vs. 639 +/- 67 microM, P less than .10). Thus, our observations indicate that U-100 insulin gives some protection against the metabolic deterioration due to the interruption of CSII so that diabetic patients may be able to remain without the pump for longer periods with concentrated rather than diluted insulin.

The O'okiep Copper District is underlain by voluminous 1035-1210 Ma granite gneiss and granite with remnants of metamorphosed supracrustal rocks. This assemblage was intruded by the 1030 Ma copper-bearing Koperberg Suite that includes jotunite, anorthosite, biotite diorite and hypersthene-bearing rocks ranging from leuconorite to hypersthenite. New sensitive high-resolution ion microprobe age data demonstrate the presence of 1700-2000 Ma zircon as xenocrysts in all of the intrusive rocks, and as detrital zircon in the metasediments of the Khurisberg Subgroup. These data are consistent with published Sm-Nd model ages of c. 1700 Ma (T-CHUR) and c. 2000 Ma (T-DM) of many of the intrusives that support a major crust-forming event in Eburnian (Hudsonian) times. In addition, U-Th-Pb analyses of zircons from all major rock units define two tectono-magmatic episodes of the Namaquan Orogeny: (1) the O'okiepian Episode (1180-1210 Ma), represented by regional granite plutonism, notably the Nababeep and Modderfontein Granite Gneisses and the Concordia and Kweekfontein Granites that accompanied and outlasted (e.g. Kweekfontein Granite) regional tectonism [F-2(D-2)] and granulite-facies metamorphism (M-2); (2) the Klondikean Episode (1020-1040 Ma), which includes the intrusion of the porphyritic Rietberg Granite and of the Koperberg Suite that are devoid of regional planar or linear fabrics. Klondikean tectonism (D-3) is reflected by major east-west-trending open folds [F-3(D-3a)], and by localized east-west-trending near-vertical ductile folds ['steep structures'; F-4(D-3b)] whose formation was broadly coeval with the intrusion of the Koperberg Suite. A regional, largely thermal, amphibolite- to granulite-facies metamorphism (M-3) accompanied D-3. This study demonstrates, inter alia, that the complete spectrum of rock-types of the Koperberg Suite, together with the Rietberg Granite, was intruded in a short time-interval (<10 Myr) at c. 1030 Ma, and that there were lengthy periods of about 150 Myr of tectonic quiescence within the Namaquan Orogeny: (1) between the O'okiepian and Klondikean Episodes; (2) from the end of the latter to the formal end of Namaquan Orogenesis 800-850 Ma ago.

Spring, W. Zeitschrift fuer Anorganische Chemie (1901), 27, 308; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). Schiff obtained a value of 4.41 for the specific gravity of cuprous iodide, while a redetermination by the author gives 5.631. The importance of this lies in the fact that cuprous iodide is now seen to be formed from the elements with contraction, whereas Schiff's figure called for twenty-four percent expansion.

Zeitschrift fuer Physikalische Chemie, Stoechiometrie und Verwandtschaftslehre (1894), 15, 65-78; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). Many metals, when heated to temperatures considerably below their melting points, exhibit properties characteristic of the liquid state. For examination in this respect, the metals were turned into cylinders with ends as perfectly plane as possible, and placed end to end in an iron holder, pressure being applied by a screw. They were heated in this condition in a hot air bath, filled, if necessary, with an indifferent gas. Cylinders of aluminium, bismuth, cadmium, copper, tin, gold, lead, zinc, antimony, and platinum were employed, and in the first experiment two cylinders of the same metal were used. The temperature was kept for from 4 to 8 hours at from 200° to 400°, and it was found that, except in the case of antimony and platinum, the cylinders had alloyed so perfectly that they could be turned with one end fixed in a lathe, whilst if broken in a vice the fracture did not take place along the original surface of separation. Pairs of different metals were next employed, usually copper or lead with some of the other metals, with the result that, at the junction, an alloy of considerable thickness was formed, 18 mm. in the case of zinc and copper, and 15 mm. in the case of cadmium and copper. In the case of lead and tin, a cavity in the end of one metal was filled with mica, so that contact only took place at the edge. An alloy was formed to the thickness of 15 mm., of which 9 mm. were in the tin and 6 mm. in the lead. By the use of cylinders of copper and zinc, in which, owing to a central cavity, contact only took place at the edges, it was found that the surface of the copper above the cavity was coloured by a yellow alloy resembling that formed when copper is subjected to the action of zinc vapour, and which was not due to diffusion from the edges (see also Abstracts, 1893, ii, 168). For the explanation of these results, which are most marked with soft and non-crystalline metals, the author points out the assumption suffices, that the molecules of solids, like those of fluids, do not all move with the same velocity.

Spring, W. Zeitschrift fuer Anorganische Chemie (1896), 13, 19; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). The presence of lithium, sodium, potassium, magnesium, strontium, calcium and barium chlorides; of potassium bromide; and of sodium and potassium nitrates has no effect upon the color of a layer of water, twenty-six meters thick. Light is absorbed by these solutions but the amount is not strictly proportional to the concentration. It is probable that the absorption is a function of the electrolytic dissociation. The author suggests that the transparency of metals may be a function of the conductivity. Reprinted with the permission of the American Chemical Society. Copyright © 2010.
