Walker-Smith, J. A., and Blomfield, J. (1973). Archives of Disease in Childhood, 48, 476. Wilson's disease or chronic copper poisoning? The case history is given of a child who presented at 14 months with ascites and was found to have severe micronodular cirrhosis with biochemical evidence of Wilson's disease, but in view of the severity of the pathology and early age of presentation, the possi...

Strains of Pseudomonas syringae able to grow on minimal medium containing 500 mg/litre of copper sulphate were selected from a collection of streptomycin-resistant strains isolated in New Zealand. From one of these copper-resistant strains a 1.3 kb fragment of DNA was isolated by PCR using primers designed on genes reported to be associated with copper resistance. Sequencing of this fragment re...

Purebred Duroc gilts were fed 0, 15, 30, or 60 ppm of supplemental copper with 100 or 200 ppm of supplemental iron throughout four reproductive cycles. Traits studied included: gestation, lactation, and weaning-to-estrus weight changes; total and live pigs farrowed; total and live pig birth weights and weaned weights at 3 weeks of age; and hemoglobin, hematocri t and plasma copper and iron of s...

1-(2-Pyridylazo)-2-naphthol has been used for extraction concentration of palladium, copper, cobalt and nickel from aqueous solutions and subsequent separation of the chelates obtained, by means of high-pressure liquid chromatography. A technique for determining microamounts of palladium in aqueous solutions in the presence of 100-fold ratio of copper and 80-fold ratio of cobalt has been develo...

The contribution of environmental surface contamination with pathogenic organisms to the development of health care-associated infections (HAI) has not been well defined. The microbial burden (MB) associated with commonly touched surfaces in intensive care units (ICUs) was determined by sampling six objects in 16 rooms in ICUs in three hospitals over 43 months. At month 23, copper-alloy surface...

This study aims to understand the acid-leaching behavior of metals from 2 to 4 mm waste printed circuit boards (WPCBs) containing 22.0% ± 1.1 Cu, 6.7% ± 0.2 Ca, 0.68% ± 0.02 Sn, 0.59 ± 0.01 % Pb, 2.71% ± 0.08 Al, 0.22% ± 0.01 Fe, etc.. Copper leaching was increased for sulfuric acid concentrations up to 1.2 mol/L and hydrogen peroxide concentrations of 10.0 vol% for a pulp density of 100 g/L at...

An experiment was conducted using a total of 420, 1-d-old, Arbor Acres commercial male chicks to compare copper sulfate and tribasic copper chloride (TBCC) as sources of supplemental copper for broilers. Chicks were randomly allotted to 1 of 7 treatments for 6 replicates of 10 birds each and were fed a basal corn-soybean meal diet (11.45 mg/kg copper) supplemented with 0, 150, 300, or 450 mg/kg...

The objective of the present experiments are to determine if sheep could safely consume high amount of PKC in their diets and if sheep's consumption of PKC require a chelating agent to tie up the high copper level in PKC to protect it against toxicity. Two experiments were carried out. Experiment 1, with four treatment groups of animals, using from 30 to 100% PKC, mixed with other feed ingredie...

Polycrystalline copper electrocatalysts have been experimentally shown to be capable of reducing CO2 into CH4 and C2H4 with relatively high selectivity, and a mechanism has recently been proposed for this reduction on the fcc(211) surface of copper, which was assumed to be the most active facet. In the current work, we use computational methods to explore the effects of the nanostructure of the...

© 2009 Ali Enteshari et al. 489 This paper focuses on assessment and design of transmission systems for distribution of digital signals over standard Category-7A copper cables at speeds beyond 10 Gbps. The main contribution of this paper is on the technical feasibility and system design for data rates of 40 Gbps and 100 Gbps over copper. Based on capacity analysis and rate optimization algorith...
