The interaction force between a rigid silica sphere and a butyl or octyl acetate droplet was measured in an aqueous environment using atomic force microscopy (AFM). The force measurements were performed without added stabilizers and the observed force behavior was found to be dependent on the type of inorganic electrolyte present, where the interfacial tension was constant over the electrolyte ...

The aim of the study was to evaluate the effect of sodium nitrate consumption on egg quality and quantity, and some blood parameters of native breeder hens of West Azerbaijan province. One hundred native hens were used from wk 25 to 32 of age. These birds were divided into two groups. One group was fed the control diet (CD) but the other fed the same diet supplemented with 4.2 g/kg sodium nitra...

D-aspartic acid (DAA), nitrate, and vitamin D3 have received considerable attention in recent years for their potential health-enhancing properties. Using an open-label design, we evaluated the impact of a DAA/sodium nitrate/ vitamin D3 dietary supplement on blood testosterone and nitrate/nitrite, as well as subjective indicators of health, in middle-aged men. Methods: 10 overweight or obese me...

Introduction: Perchlorate reducing bacteria may serve as model organisms for potential life forms that could exist on Mars. Due to the high reduction potential of perchlorate it can be utilized in microbial metabolism as an electron acceptor [1]. Perchlorate was discovered to be present in martain surface materials (~0.5% wt.) using the Wet Chemistry Laboratory and the Thermal and Evolved Gas A...

RATIONALE Because of the threat of bombings using improvised explosives containing ammonium nitrate (AN), law enforcement and intelligence communities have been interested in stable isotope techniques for tracking and discriminating AN sources. Separate analysis of the AN component ions ammonium and nitrate would add discriminatory power to these techniques. METHODS Ammonium ions in dissolved...

Another way of expressing 200 ppm is to say it is 1 pound of sodium nitrite in 5,000 pounds of meat. Effective June 15,1978, the USDA changed the curing procedures of “pumped” bacon as follows: the use of sodium nitrate and potassium nitrate is prohibited; the level of ingoing sodium nitrite shall be 120 ppm (or 148 ppm potassium nitrite); the level of ingoing sodium ascorbate (vitamin C) or so...

abstract regarding to this issue that nitrogen is one of the main essential elements for plant that growth and efficiency of plant is related to it, and on the other hand most of the water and soil resources in iran are alkaline; in order to evaluation of the interactive effect of different concentrations of sodium bicarbonate and nitrogen form on snap bean in hydroponic system, this research w...
