to·pol·o·gy

 (tə-pŏl′ə-jē)
n. pl. to·pol·o·gies
1. Topographic study of a given place, especially the history of a region as indicated by its topography.
2. Medicine The anatomical structure of a specific area or part of the body.
3. Mathematics
a. The study of certain properties that do not change as geometric figures or spaces undergo continuous deformation. These properties include openness, nearness, connectedness, and continuity.
b. The underlying structure that gives rise to such properties for a given figure or space: The topology of a doughnut and a picture frame are equivalent.
4. Computers The arrangement in which the nodes of a network are connected to each other.

In conjunction with the results obtained by other authors, the greatest recombination rate determined in our study coincided with regions 21q22.13 to 22.2 of the distal region of chromosome 21 (Graphic 5), in chromatin areas associated to DSCR2 where we observed a high degree of chromatin decondensation and methylation of different Lysine residues of H3 in a way that the structure ofthe meiotic functional apparatus would correlate with the topologic and epigenetic state ofthe chromatin associated to DSCR where, as we have shown, chromatin undergoes structural remodeling, very possibly induced by fine epigenetic control.
Thus, what the students learnt in terms of the definition and examples of topologic space were specified as well as possible misconceptions.

Square data were imported into MapInfo Professional version 6.5 GIS software, and topologic links for each WS% category were generated using Queen's contiguity up to the seventh-order lag.
The weights of the best matching and the units in its topologic neighborhood are then updated towards x(n) with rule [w.sub.i] (n+1) = [w.sub.i] (n) + a(n) [h.sub.i,b](n) (x(n) --[w.sub.i](n)), where i [??] [V.sub.M] and 0[pounds sterling]a(n) 1 [pounds sterling] is a scalar valued adaptation gain.
Whereas connectivity is based on topologic distance--meaning that all routes between nodes are considered to be the same length--valued graph analysis uses actual route distances.
The descriptors that have been used for QSAR analysis include hydrophobicity [log [K.sub.ow], CLogP, (octanol/water partition coefficient calculated by Hansch's method), and MLogP (octanol/water partition coefficient calculated by Moriguchi's method)], size [MW (molecular weight) and MgVol (molar volume calculated by McGowan's method)], polarizability [CMR, (molar refractivity calculated by Hansch's method), AMR (calculated by Ghose and Crippen's method), and PolarizG (polarizability calculated by Glen's method)], and constitutional descriptors [TPSA (topologic polar surface area), HBA (number of hydrogen-bond acceptors), nCL (number of chlorines), and nBR (number of bromines)] (Table 3) (Abraham and McGowan 1987; Ghose and Crippen 1987; Glen 1994; Leo et al.
Using a largely programmatic process, the data was migrated from the collection environment to the final data model--including attributation and topologic building.
The topologic scheduling begins when the relations' assignment is finished.
