A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of suppleme...

Abstract At the Exótica deposit, south of giant porphyry copper deposit Chuquicamata (Atacama Desert, Chile), Cu-rich groundwater seeped out at several locations in open pit (Mina Sur) during sampling 2009–2011. their outflows, these solutions formed blueish and greenish copper-bearing gel-like precipitates. These gels contained atacamite sulfate hydroxides such as devilline, spangolite, posnja...

wilson’s disease (wd) or hepato-lenticular degeneration is a rare autosomal-recessive disorder. a prevalence rate of 30 cases per million and a birth incidence rate of one per 30,000 to 40,000 are often quoted. in 40 to 50% of individuals with wd, hepatic dysfunction is the initial clinical manifestation. with the exception of liver transplantation, treatment of wd is only palliative and intend...

Some years ago a group of experimentalists (l-3) observed that the scouring of cattle on the so called “teart” pastures of England could be traced to the high molybdenum content of the soil and herbage. Feeding molybdenum salts reproduced the symptoms. Subsequently it was found t:hat feeding copper sulfate as a drench prevented or cured the condition. Apparent.ly a similar high molybdenum area ...

Copper and copper alloys have found applications in various industries. One of the main reasons Cu its are utilized widely is that they sufficient corrosion resistance key environments, such as seawater anoxic solutions; however, localized processes might occur presence aggressive anions, oxygen, or an increase solution pH. In critical Cu, susceptibility to corrosion, specifically pitting, must...

copper is a very common element in water resources. for this reason, concerns about the risks and consequences of this element in water contamination are arising. the purpose of this study was to investigate the effects of water-born cuo (copper (ii) oxide) on the rainbow trout, oncorhynchus mykiss gill tissue to establish a suitable biomarker for copper in water resources. samples with 18±3g b...

The objectives of this research are twofold: (a) to review current methods for rapid analysis dissolved protein in water and wastewater (b) introduce a new spectrophotometrical method determination proteins the 10–2500 mg/L range using carbonate-tartrate reagent, phosphomolybdic-phosphotungstic copper sulfate.

Natural dye extracted from Caesalpinia sappan Linn. was applied to a cotton fabric and silk yarn by dyeing process. The dyestuff component of Caesalpinia sappan Linn. was extracted using water and ethanol. Analytical studies such as UV–VIS spectrophotometry and gravimetric analysis were performed on the extracts. Brazilein, the major dyestuff component of Caesalpinia sappan Linn. was confirmed ...
