A family outbreak of methaemoglobinaemia following ingestion of sausages made using 'saltpetre' is reported. Saltpetre is a generic term for several potassium and sodium based compounds. On this occasion imprecise ordering led to the use of sodium nitrite rather than the usual potassium nitrate, with extremely serious consequences.
In order to investigate the effect of different ratios of ammonium: nitrate on the photosynthesis and fatty acid composition in canola (Brassica napus L.) under different levels of salinity, an experiment was conducted as a factorial based on complete randomize design at Agricultural Research Center in East Azerbaijan in 2010. The first factor was different ratios of nitrogen sources to ammoniu...
milk thistle (silybum marianum l. gaertner) is an annual or biannual plant of the asteraceae family. this species is important not only as a medicinal plant traditionally, but also as an endemic plant to protect vegetative and natural resources in iran. this experiment was carried out to find the most effective treatments to break milk thistle seed dormancy and improve its cultivation in vast s...
The effect of carbon nanotubes, calcium chloride and potassium nitrate on germination traits Iranian Oak seed (Quercus brantii)
in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...
The existing evidence for the nature of the phase diagram for the binary system sodium nitrate-potassium nitrate is reviewed and in particular whether the system is of the continuous solid solution type, as has often been stated in the last 80 years, or whether this system is of the eutectic type as was earlier believed and has again been asserted recently. Additional evidence from Raman spectr...
Extend abstract Introduction: Guava (Psidium guajava L.) is one of the most important fruit crops of tropical and subtropical regions. Guava (Psidium guajava L.) can be propagated by seed, layering, grafting, cutting or tissue culture. Propagation by seed is used for the production of seedlings usable in breeding programs or rootstock production for grafting. Guava seeds germinate poorly and u...
Potassium borates, which are widely used in welding and metal refining industry, as a lubricating oil additive, cement additive, fiberglass additive and insulation compound, are one of the important groups of borate minerals. In this study the production of a potassium borate mineral via hydrothermal method is aimed. The potassium source of potassium nitrate (KNO3) was used along with a sodium ...
