This paper describes the applicability of a Hg-electroplated-Pt ultramicroelectrode in the quantification of elemental sulphur in naphtha samples by square-wave voltammetry. A reproducible deposition methodology was studied and is reported in this paper. This methodology is innovative and relies on the quality of the mercury stock solution to obtain reproducible surfaces required for the analyt...

Although chemical agents were not employed as offensive weapons during the past war, nevertheless it was imperative to pursue vigorously investigations on the treatment of chemical warfare casualties. Inasmuch as a number of chemical warfare agents contain arsenic, attention was focused on the synthesis of compounds capable of antagonizing the local and systemic effects of arsenical vesicants. ...

The extent of the oxidation of the sulfur of the amino acid, cystine, by the animal organism has been the subject of frequent study (1, 2). It has been shown that the sulfur of cystine administered in moderate quantities is oxidized readily and excreted in bhe urine chiefly as sulfate sulfur. Variable recoveries of the sulfur of cystine when fed are frequently obtained, owing presumably to t,he...

This study was conducted to determine the effect of dietary fructan supplementation on growth performance, nutrient digestibility, meat quality, fecal microbial flora, and fecal noxious gas emission in finishing pigs. A total of 96 finishing pigs [(Yorkshire×Landrace)×Duroc] with an average BW of 73.1±2.5 kg were used in a 6-wk study. Pigs were randomly allotted to 1 of 3 dietary treatments: 1)...

Diphosphopyridine nucleotide reacts chemically with a number of reagents, including alkali (l), cyanide (2, 3), bisulfite ions (2, 3), dihydroxyacetone (4), dithionite ions (5), hydroxylamine (6), mercaptans (7), and aromatic amines (8). All of these reagents are nucleophilic agents which react on a positive center. It is generally assumed that these reactions involve the addition of the nucleo...

In the process of improving gas turbine engines (GTE), increasing resource and efficiency, there is a constant increase in temperature pressure working fluid. Turbine elements are subjected to high thermomechanical loads continuous exposure from aggressive environment. These impacts especially significant for blades first stages turbine, located area highest temperatures. One most serious types...
