Where the exchange of goods and services were concerned, it seems that the writers had a tendency to select "variation in the expression of a given meaning" (Halliday 1994: 342) as a politeness strategy in order to ask the recipient to perform an action.
The total oxidation of methane was studied over a Pd-Pt/Al2O3 catalyst with selected variations of typical gaseous emission components of natural gas engines being oxygen, methane, water, carbon dioxide, higher hydrocarbons, CO, NOx, and SO2.
Two selected variations in the hESC lines, the deletions of the GRB10 gene in HS293 and the MLLT1 gene in HS401, were verified by designing PCR amplicons within the deleted segments.
The user interface allows searching for somatic mutations or copy number alteration across different samples and cancer studies selecting variations occurring in user-defined gene list or in 22 predefined groups cancer-specific genes.
In each of these two families, the co-occurrence of transmembrane helices or C2/C2 (BZF finger) domains with a selected variation on the RING finger has been subjected to strong selection pressure in order to preserve their unique domain architectures during evolution.
Firstly, we compare the selected variation operators in pairs, each operator with a modification of itself, in which we remove those elements related to the Pareto efficiency.
The production of cultivars generally entails considerable human involvement although in a few cases it may be as little as simply selecting variation from plants growing in the wild (whether by collecting growing tissue to propagate from or by gathering seed).
Patterns are thought to arise from the local recombination landscape, influencing the degree to which neutral variation experiences hitchhiking with selected variation.
The quite recent estimate for the age of MRCA for each island could be due to a founder effect followed by the effect of genetic drift in small populations [ 5], as well as by fixation of selected variation.
