This paper introduces a new method for a one-step determination of ammonia nitrogen (NH3) in high complex solid and liquid samples from the agricultural and livestock sectors.
A simple and reliable solid phase microextraction/gas chromatography mass spectrometry (SPME/GC MS) method was developed for the single-step determination of PCBs 126 and 153 in rat brain and serum, using liquid/liquid and solid phase extraction (SPE) as reference techniques.
At the end of GA steps, determination of mutation rate is described in detailed.
At the end of GA steps, determination of crossover probability is described in detailed.
Design of each feeder contains the following steps: determination of the feeder-neck connection point on the casting surface, initial feeder design, feeder shape optimization and feeder topology optimization.
I wanted a name that conveyed a sense of step-by-step determination.
All members of the ModuLand method family are based on the following common steps: Determination of influence functions: If a node lies in a module, than its influence on the links of the given module is typically larger than on more distant links of the network.
The level of resolution achieved was suitable for the purpose of this investigation and permitted a relatively simple one-step determination of Tm.
The procedures described in Introduction allow direct one-step determination of components of diesel fuel additives, if they have a characteristic mass spectrum, by using GC-MS in the SIM mode or by other selective detection methods.
