The partition function Z is given in the large-P limit, Z = limp co Zp, and expectation values of an observable are given as averages of corresponding estimators with the canonical measure in Eq. (19). The variables and R ( ) can be used as classical variables and classical Monte Carlo simulation techniques can be applied for the computation of averages. Note that if we formally put P = 1 in Eq. (19) we recover classical statistical mechanics, of course.

Gusewell (2004) has pointed out that interspecific competition in P-limited habitats might be less than that in N-limited ones, so that species coexistence could be favored under P limitation. For example, there are several forms of P in soils, so that different species can exploit distinct P pools (van Ray and van Diest 1979 Haynes 1992 Nuruzzaman et al. 2006). We have already seen that plant species...

The sensitivity, compactness, automation, and low prices of ion trap instruments made them very popular in biological MS P Limitations of ion traps include low resolution and mass accuracy at high m/z. In addition, in MS/MS mode, the lower end of the fragment mass range cannot be visualized. Recent developments in the linear geometry of ion traps are aimed at improving on those limitations. 

A second possibility consists of experimentally determining the SST limits from measurements at the worst-case conditions (n measurements with standard deviation 9,12,13 gg-p limit is defined as the lower or upper limit of the one-sided 95% confidence interval around the worst-case average result. For example, for resolution, the lower limit will be considered, while for migration time it would be the upper. The confidence intervals are defined as in Equations (16) and (17), when considering the lower or the upper limit, respectively.

In many wetlands NPP and decomposition are most limited by the availability of nutrients, especially N and P. For example, in a review of published data on nutrient limitations in North American bogs, fens, marshes and swamps, Bedford et al. (1999) found that a large proportion of the wetlands were either P limited or limited by both N and P, especially those occurring on organic soils. Only marshes had N P ratios in both live tissues and soils that consistently indicated N limitation, though the soil data suggested that the majority of swamps were also... 

Ascorbic acid ( Vitamin C ). The crystal structure of this substance cannot be said to be established with the certainty and precision we associate with those already described nevertheless, there is no reason to doubt that the structure suggested by Cox and Goodwin (1936) on the basis of p, limited study of the X-ray reflections is essentially correct. The work is described here because this crystal structure presents some very interesting and instructive features. It is also historically interesting because a preliminary study by optical and X-ray methods played a part in the elucidation of the chemical structure of this biologically important substance. (Cox, 1932 a Cox, Hirst, and Reynolds, 1932 Cox and Hirst, 1933.)...
