Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...

The chlorophyll a:b ratio was shifted in Chlorella vannielii by varying the illuminance under which the cells were cultured-the ratio increased from 2.9, 3.0, 4.0, and 4.8 to 6.2, respectively, at 100, 300, 900, 2,700 and 6,000 foot candles. The 6,000-foot candle cells retained an optimal growth rate at the chlorophyll a:b ratio of 6.2 which was the upper limit of normal growth. Comparisons wer...

The young journal Electrochemical Science Advances copublished by Wiley-VCH and Chemistry Europe has had a great start. Its constitution reflects the increasing interest in electrochemical research development. content is therefore devoted not only to fundamental electrochemistry but (importantly) consequential applications like generation storage of electricity, photovoltaics, corrosion, senso...

devices originally described by Clark and Bargeron1 in 1959 provide a simple, rapid and reproducible means of detecting and localizing intracardiac shunts. Their clinical application has been well documented in the past five years.25 This paper will describe a modification of the platinum electrode and its application and a modification of the method of hydrogen gas administration. The advantag...

A method has been developed for the continuous monitoring of oxygen tension in solutions and gases. The oxygen is reduced at a platinum surface which is covered with a plastic membrane. The silver-silver oxide reference electrode is also included under the membrane. Drift is less than 10 per cent for a period of days, and temperature compcnsation is possible. A number of uses to which it has be...

Several oxovanadium (IV) complexes of pyradoxamine (PM), pyridoxol (P), pyridoxal (PL), and glycinehydroxamate (GX) were obtained as a result of potentiometric data analysis using SUPERQUAD at I = 0.15 M NaCl and T = 25°C. Protonated, unprotonated and hydroxospecies were detected in solutions. No polymeric species of oxovanadium(IV) were found under the experimental conditions used. Differentia...
