Geographical information system (GIS) and remote sensing technique is a tool which is used for acquiring data from space, storing, analyzing and displaying spatial data, also can use for investigating...
This study evaluated the effect of acid whey and freeze-dried cranberries on the physicochemical characteristics, lipid oxidation and fatty acid composition of nitrite-free fermented sausage made from...
Making a Better Nitrate Test Kit     Better Nitrate  Test Kit       2015/8/13
The dull black plastic of the device on Joshua Pearce’s desk belies its usefulness. Pearce picks up the box, which has a switch on the side and a small opening on top. A handful of vials sit in a bag ...
High nitrate concentration in groundwater is a major problem in agricultural areas in Iran. Nitrate pollution in groundwater of the particular regions in Isfahan province of Iran has been investigated...
Removal of ammonia nitrogen and nitrate nitrogen by an heterotrophic nitrification-aerobic denitrification strain is an economical and effective method. In this article, a kind of heterotrophic nitrif...
Nitrate-nitrogen content of groundwater are ever-increasing in underneath vegetable growing areas, in this paper, based on field test of cucumber cultivated in Solar Greenhouse in North China, we stud...
Previous studies showed contradictory findings regarding the relationship between nitrate in drinking well-water and abnormal methemoglobin (MetHb) level (>2%) among children. We studied the effect of...
The antioxidant activity of ethanolic seed extract of Hibiscus sabdariffa l. was investigated in toxicity induced by chronic administration of sodium nitrate in wistar rats. Twenty-five adult wistar r...
Significant amounts of ammonia, nitric acid and hydrochloric acid as ammonium particle precursors have been found in urban polluted air. In order to advance understanding the formation and dissociati...
Bench-scale soil column experiments were performed to examine the e ects of soil type and in ltration conditions on the removal eciencies of wastewater nitrites and nitrates during the biological rip...
We measured denitrification rates using a field 15NO3- tracer-addition approach in a large, cross-site study of nitrate uptake in reference, agricultural, and suburban-urban streams. We measured denit...
We measured uptake length of 15NO3- in 72 streams in eight regions across the United States and Puerto Rico to develop quantitative predictive models on controls of NO3- uptake length. As part of the ...
This study was carried out to investigate the NO 3 content of well waters in the Kumluca Region. For this purpose, water samples were taken from 20 wells in the Region on 13 th May 1996. In water sam...
Physico-chemical and mechanical properties of extruded cornstarch-poly(lactic acid) (PLA) with addition of ceric ammonium nitrate (CAN) were investigated. An addition of 0.25% CAN improved bulk densit...
Nitrate poisoning occurs when nitrite is absorbed into the blood, where it changes the red-colored blood pigment, called hemoglobin, to methemoglobin. Hemoglobin carries oxygen from the lungs to the o...
