Four groups of three ram lambs were fed, in group pens, the following diets from 4 to 19 wk of age: 1) control (6 mg Cu/kg and 1 mg Mo/kg); 2) control plus 10 mg Cu/kg; 3) control plus 10 mg Mo/kg and 4) control plus 10 mg/kg of both Cu and Mo. Copper and Mo were added to the diet as copper sulfate and sodium molybdate. The main ingredients of the diets were alfalfa hay (20%), oats (20%) and co...

We have established the optimal conditions for use of sodium borohydride as the reducing agent before the direct determination of mercury in water, urine, and blood by atomic absorption spectroscopy. We evaluated the effects of pH, temperature, and cupric sulfate concentration on the direct determination of both organic and inorganic compounds of mercury. Accurate and precise quantification of ...

This paper compares the performance in terms of delay and power of Multi Walled Carbon Nanotubes (MWCNT)based interconnects at 22nm technology node. Similar analysis is carried out for copper based interconnect and results are compared with MWCNT at different interconnect lengths. This analysis shows that due to low resistance and inductance MWCNT bundle interconnect is of lower delay and power...

BACKGROUND Penicillamine, once considered the cornerstone of treatment for Wilson disease (WD), is rather expensive and toxic, and often causes neurological worsening. Zinc sulphate, aiming at the treatment of free-copper toxicosis, has emerged as effective, safe and cheap alternative. AIM To assess the effect of withdrawal of penicillamine from maintenance treatment with penicillamine and zi...

In 2007, it was shown that the shipping of lead (Pb) through Esperance Port in Western Australia resulted in contamination and increased Pb concentrations in children. A clean-up strategy was implemented; however, little attention was given to other metals. In consultation with the community, a cross-sectional exposure study was designed. Thirty-nine children aged 1 to 12 years provided samples...

Urinary arsenic species have been determined for approximately 3000 urine samples obtained from residents of a community surrounding an arsenic-emitting copper smelter. Levels of inorganic, monomethylated and dimethylated arsenic species ranged from less than 1 microgram/L (the instrumental detection limit) to 180 micrograms/L seen for dimethyl arsenic. Comparison of a subsample of this populat...

An 83-year-old woman taking isoniazid (INH) suddenly developed a headache, palpitations, and skin eruptions with itching while eating raw tuna. The symptoms were compatible with those of histamine intoxication. When given fresh raw tuna to eat, no such reactions were evoked in this patient. The episode was speculated to be due to two conditions; eating spoiled raw tuna and at the same time bein...

We have investigated the structures, electronic structures and magnetic properties of the triazine-based g-C3N4 (gt-C3N4) monolayer doped with B, Al, and Cu atoms based on density functional theory using ab initio calculations. The B atom prefers to be situated at the center of the triazine ring, whereas the Al and Cu atoms tend to be located above the center of the triazine ring. The doping at...

Increased portability, versatility and ubiquity of electronics devices are a result of their progressive miniaturization, requiring current flow through narrow channels. Present-day devices operate close to the maximum current-carrying-capacity (that is, ampacity) of conductors (such as copper and gold), leading to decreased lifetime and performance, creating demand for new conductors with high...

WHO reports estimate poisoning as one of the most common causes of increased morbidity and mortality rate world-wide. Various agents such as pesticides, drugs have been used for intentional and accidental poisoning in different countries. In the Indian scenario, pesticides are the most commonly used poisoning agents. To assess the prevalence and mortality incidence rate due to various poisoning...
