to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with th...

AIM To assess plasma zinc and copper concentration in individuals with Asperger's Syndrome, Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) and autistic disorder, and to analyze the efficacy of zinc therapy on the normalization of zinc and copper levels and symptom severity in these disorders. SUBJECTS AND METHODS Plasma from 79 autistic individuals, 52 individuals with PDD...

Serum and aqueous humour zinc and copper concentrations of 44 patients with glaucoma and cataract were determined. Serum values were found within normal ranges. The highest mean copper concentration was seen in the glaucoma group. In addition there was a significant negative correlation between the aqueous humour levels of zinc and copper in patients with glaucoma. It was concluded that an incr...

SUMMARY The purpose of this study is to compare the level of zinc, copper and the ratio of zinc to copper in serum of patients who are suffering from acute myocardial infarction with healthy men. In 10 ml blood samples from 45 men on the second day of myocardial infarction and 51 healthy men volunteers matched for age, serum zinc, copper, cholesterol and triglycerides were measured. Zinc and c...

The aim of this study was to examine the contamination of game meat with copper and zinc and establish whether the use of alternative (non-lead) ammunition can lead to higher or unsafe levels of copper and zinc in the meat of roe deer, wild boar and red deer. The research project "Safety of game meat obtained through hunting" (LEMISI) was conducted in Germany with the purpose of examining the e...

The extraction and separation of copper(II), zinc(II), cobalt(II), and cadmium(II) were investigated. Both copper(II) and zinc(II) formed ammine-complexes, while cadmium(II) and cobalt(II) formed hydroxide precipitates in an ammonia medium. By the addition of sodium dodecylsulfate (SDS), a copper(II) complex formed an ion-pair (copper-ammine-DS), which was extracted into the SDS phase. However,...

The Sungun copper deposit is located in about 40km north west of Ahar city in the east Azarbaigan province of Iran. The total geological ore deposit is estimated to be 740 million tons. In this study using all information from exploration and geotechnical studies of the area, final pit limits of Sungun copper deposit is designed by the 2-D Lerchs & Grossmann Algorithm. By this method, from 740 ...

OBJECTIVES 1) to determine zinc and copper levels of contamination in the individual component solutions used to prepare the pediatric total parenteral nutrition mixtures in Argentina; 2) to compare zinc and copper amounts prescribed by the physician with the true amount given to a neonate weighing 1.2 kg and to a child weighing 10 kg, who would receive total parenteral nutrition formulas prepa...

We have developed an electroformed copper lining having highly clean and smooth surface (i.e. little outgassing and high conductive copper) for use in accelerator components. The copper lining is produced by periodic current reversal electroforming with a low copper-content acid copper sulfate bath containing the specified amount of chloride ions (PR process). Deposit by PR process has the same...

Metallothionein is a copper- and zinc-binding protein present in most, if not all, tissues of higher eukaryotic species of animals. This review focuses on what is currently known about the characteristics, detection, occurrence, synthesis and turnover of metallothionein, specifically in livestock animals. The function of metallothionein in copper and zinc metabolism, though widely acknowledged,...
