An analysis is presented for both ground- and satellite-based retrievals of total column ozone and nitrogen dioxide levels from the Washington, D.C., and Baltimore, Maryland, metropolitan area during the NASA-sponsored July 2011 campaign of Deriving Information on Surface COnditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ). Satellite retrievals of t...

Abstract As nitrogen source is a necessary element in structure and cell metabolism, studying of nitrogen source and its effect on growth and different behave of photosynthetic organisms has received much attention. In this study, the comparative effects of three nitrogen sources (KNO3, NH4Cl and KNO3+NH4Cl) have been studied on physiological properties of two Dunaliella species, as ...

Nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. Analyses included total nitrogen (TN), non-casein nitrogen (NCN), non-proteinnitrogen (NPN), casein nitrogen (CN) and proteolysis index (PI). Yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°C. TN, CN and PI contentsof yoghurt milk samples with high Somatic Cell SC...

A 4 days study was conducted to determine the effects of Different concentration of bioaugmentor bacterial strain Bacillus licheniformisi, B. subtilis, B. polymyxa, B. laterosporus and B. circulans (Protexin Aquatech, UK) on adjustment of parameters of water quality as TAN, NO2-N, NO3-N and turbidity from the effluent of Common Carp ponds. Effects of time and concentration were studied as a com...

This work focuses on the prediction of the two main nitrogenous variables that describe the water quality at the effluent of a Wastewater Treatment Plant. We have developed two kind of Neural Networks architectures based on considering only one output or, in the other hand, the usual five effluent variables that define the water quality: suspended solids, biochemical organic matter, chemical or...

We measured total dissolved reactive nitrogen in precipitation samples collected at Uljin, a Korean coastal site upwind of the southern East Sea/Sea of Japan (EJS), selected as a representative study site of atmospheric deposition over the northwestern Pacific margin. NO−3 was found to be the most abundant nitrogen species, followed by NH+4 and dissolved organic nitrogen (DON). Air-mass back-tr...
