  total nitrogen
The effects of nitrogen and phosphorus supply on chlorophyll biosynthesis, total nitrogen content, and photosynthetic rate were studied.
      
The total nitrogen contents in leaves increased as nitrate concentrations increased.
      
3) When phosphate concentrations increased from 0.125 to 1 mmol/L, the total nitrogen contents in leaves slightly increased; however, continuous increase of phosphate concentrations resulted in the decrease in total nitrogen contents in leaves.
      
Moreover, nitrogen supply levels affected contents of total nitrogen and soluble proteins in leaves, and net photosynthetic rates.
      
The content of total nitrogen and total potassium of litter in gap were 10.47% and 20.73% higher than those under canopy, however, the content of total phosphorus and organic carbon under canopy were 15.23% and 12.66% more than those under canopy.

  tn
Moreover we give some conditions so thatF*(?[t1,...,tn-1]) is the ring of invariants of φ.
      
For any ε >amp;gt; 0, we construct an orthonormal Schauder basis of C(K) consisting of trigonometric polynomials Tn n = 1, 2, .
      
The theorem is then used to characterize a class of entire functions that can be reconstructed from their sample values at the points tn = an + b if n = 0, 1, 2, ...
      
and tn = an + c if n = 0, -1, -2, ..., where a, b, c are arbitrary constants.
      
It is well known that for certain sequences {tn}n∈? the usual Lp norm ∥·∥p in the Paley-Wiener space PWτp is equivalent to the discrete norm ‖f‖p,{tn}:=(∑n=-∞∞|f(tn)|p)1/p for 1 ≤ p = >amp;lt; ∞ and ‖f‖∞,{tn}:=supn∈?|f(tn| for p=∞).

Results showed that shrub rehabilitation and development enhanced accumulation of organic C and total N.
      
The total N and P contents in different organs of aboveground part all descended monotonically in growth season, with the order of leaf>amp;gt;vagina>amp;gt;stem.
      
The change of total N content in roots of the two types of C.
      
The content of total N, ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3--N), especially of NH4+-N and NO3--N, varied widely in different organs, with NH4+-N/NO3--N>amp;gt;1.
      
Organic C, total N, available N and available K content increased gradually, and soil fertility was enhanced.

  total-nitrogen
The levels of total-nitrogen decreased from 3% in the meconium to 0.57% with normal mixed diet or in adults.
      
More than 90% of COD-removal efficiency and over 80% of total-nitrogen-removal efficiency were obtained using three aerobic-anoxic cycles per day at an aeration ratio of 50% and with a hydraulic retention time of 10 h.
      
Accordingly, at higher C/N ratios, these substances caused major increases in effluent total-nitrogen and organic-carbon concentrations.
      
Chlorophyll concentration was strongly linked to the total-nitrogen concentration.
      
Subsequently, net nutrient loads from agriculture continued to increase, reaching an annual load of 2652 tons total-nitrogen and 70 tons total-phosphorus for the River K?vlinge?n.
