The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatography (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophosphite and phosphate in several p...

in order to investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...

to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...

pushover analysis is a simplified nonlinear analysis technique that can be used to estimate the dynamic demands imposed on a structure under earthquake excitations. one of the first steps taken in this approximate solution is to assess the maximum roof displacement, known as target displacement, using the base shear versus roof displacement diagram. that could be done by the so-called dynamic p...

We show that the A4 discrete symmetry that naturally leads to tri-bimaximal neutrino mixing can be simply obtained as a result of an orbifolding starting from a model in 6 dimensions. This particular orbifolding has four fixed points where 4 dimensional branes are located and the tetrahedral symmetry of A4 connects these branes. In this approach A4 appears after the reduction from six to four d...

Abstract A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes enhance canola productivity. The carried out at Agronomy Research Farm, University Agriculture Peshawar in winter 2016-2017. experiment randomized complete block factorial design. study comprised three factors including (60, 120 180 kg ha-1), phosphorous (70, 100 130...

For a long time, the only acceptable treatment for a white phosphorous burn was to keep it covered with water until a physician extracted the phosphorous. When the water dried up or ran-off, contact with air caused the burn to re-ignite. This is a serious problem, especially under battle conditions where water may by scarce or non-existent, and the ability to remove the victim quickly to a trea...

abstract- to investigate the effects of bio-chemical and organic fertilizers on yield and seeds npk contents of pumpkin (cucurbita pepo var. styriaca), an experiment was conducted at the research farm of kurdistan university in 2009 growing season. treatments were included 1) control, 2) seeds inoculated with free-living n fixing bacteria (nfb), 3) seeds inoculated with phosphate-solubilizing b...

A method is described that accurately and rapidly quantifies the free and total phosphorous content of a commercially available, purified, phytic acid preparation. This allows its use as a standard for phytic acid determinations in foods. The method involves a wet ashing step followed by phosphorous measurement with a 1-amino-2-naphthol-4-sulfonic acid-molybdate reagent in a microplate reader a...
