The mass of nutrients (nitrogen, phosphorus, potassium, and calcium) imported during 1984 and 1985 to the North Inlet Estuary, Georgetown County, South Carolina, by precipitation and runoff was compared with that imported by a colonial-nesting wading bird, the white ibis (Eudocimus albus). From late March through late June of both years, breeding ibises imported nutrients to the North Inlet Est...

The intracellular concentrations of sodium, chloride, phosphorus and potassium under normal conditions in pavement epithelial (PE) cells of brown trout (Salmo trutta) gill were 66, 51, 87 and 88 mmol l-1 respectively. The concentrations of these elements under identical conditions in mitochondria-rich (MR) cells were not significantly different, except for that of chlorine, which was lower in M...

Many microorganisms accumulate phosphor as polyphosphates. This paper highlights the great importance of filamentous microorganisms. So far the ability to store phosphorus in volutin granules by filamentous microorganisms has not been evaluated. The aim of this research was to prove the ability to store phosphorus in volutin granules as well as to show the meaning of potassium and magnesium ion...

application of sewage sludge as a cheap and waste material is increasing for supporting plant essential elements especially in the soils of arid and semiarid regions. in the present greenhouse research, the effect of ardabil municipal sewage sludge on n, p, k, pb, cr, ni and cd concentrations in soil and plant and also spring wheat yield and growth indices was studied as a randomized complete b...

the present study aimed at estimating the amount of carbon storage and its relationship with other physical and chemical soil properties in four land-use systems including intact, protected, exploited and garden-uses areas in the northern zagros region in west azarbaijan province, iran. thirty sample plots were identified and within each plot, soil samples were taken in each land use and each s...

in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...

Creatinine plays a key role in the function and maturation of fetal kidneys throughout pregnancy. It is important to identify other markers that may help in the diagnosis of renal dysfunction. Our aim was to determine the profile of and the correlation between biochemical markers to be used to assess renal function and maturation of the fetus in the amniotic fluid during pregnancy and to determ...
