A simultaneously physical, psychical, and topographical realm, the dacha world exists as a dimension that is fully present to its inhabitants, a point underscored in dachniki s observations that they felt more alive, more attuned to the world around them, and more human at their dachas. How, then, can this notion of presentism and immediacy be reconciled with the perception that dachas, and leisure life more generally, belong to a dimension that is set apart from everyday life In actuality, these two perspectives are not mutually exclusive but constitute another paradoxical feature of dachas. Specifically, it is these distancing tactics that foster the construction of the dacha world as an enchanted place— another planet. The values and qualities that are believed to characterize the dacha world derive directly from rhetorical tactics that locate it elsewhere, in a state of excep-tionalism separate from the banalities of everyday life. 

Figure 4.11 shows the typical pyrograms of several PP samples in the mass chromatogram mode at m/z = 310. For the sample ML-A, 10 peaks are clearly separated in the mass chromatogram that correspond to the number of possible C22 products. The pentad tacticity of these 10 peaks can be assigned as shown in Figure 4.11 based on the general tendency for elution (the products with the meso-structure elute faster) and the observed peak intensities for the PP samples with various stereospecificities.
