Dissolved organic nitrogen (DON) and carbon (DOC) often dominate the dissolved nitrogen and organic carbon fluxes from rivers, yet they are not considered to affect coastal water quality because of their assumed refractory nature. The objective of this study was to quantify DON and DOC bioavailability to bacteria in 9 rivers on the east coast of the United States during a 6 d dark bioassay expe...

The objective of this study was to estimate genetic associations of prolificacy traits with other traits under selection in the Finnish Landrace and Large White populations. The prolificacy traits evaluated were total number of piglets born, number of stillborn piglets, piglet mortality during suckling, age at first farrowing, and first farrowing interval. Genetic correlations were estimated wi...

introduction: leptin is a hormone resulting from the obesity gene which could be important in the pathogenesis of the insulin. only limited data concerning the interaction of insulin, glucose tolerance and free leptin are available and no data exist on the potential influence of free vs. bound circulating leptin. we, therefore, studied percentage of free to total leptin in diabetic patients. ma...

improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...

Fifty-seven typical surface soils and 108 deeper soils were collected from five former industrial sites in Beijing and concentrations of total Hg (SigmaHg) as well as pH, total carbon (TC), total nitrogen (TN), total sulfur, and dissolved organic carbon concentrations determined. The mean concentration of SigmaHg in surface soils was significantly greater than background concentrations in the v...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...

Many estuaries are becoming increasingly eutrophic from human activities within their catchments. Nutrient loads often are used to assess risk of eutrophication to estuaries, but such data are expensive and time consuming to obtain. We compared the percent of fertilized land within a catchment, dissolved inorganic nitrogen loads, catchment to estuary area ratio and flushing time as predictors o...

Nutritional assessment was carried out on fifty haemodialyzed patients by demographic, anthropometric, biochemical and dietary indices. The mean age of the patients was 49 years with a male to female ratio of 2.3:1. The duration of dialysis ranged from 6 to 40 months with a mean of 25 months. Fifty percent of the patients were moderately nourished based on their body weight 44%, body mass index...

A proteomic approach was used to analyze protein changes during nitrogen mobilization (N mobilization) from leaves to filling seeds in pea (Pisum sativum). First, proteome reference maps were established for mature leaves and stems. They displayed around 190 Coomassie Blue-stained spots with pIs from 4 to 7. A total of 130 spots were identified by mass spectrometry as corresponding to 80 differ...
