Abstract:

The subject of this research is the soils and soil-geochemical catenae in the area of Yeletsky settlement, located in the northeast of the Komi Republic. Catena were deposited on the mound covered with moss-shrub tundra transect from the interfluve of Usa and Yelets Rivers to a lacustrine depression, complicated by arching permafrost mounds. Within the district of research, the authors laid five soil incisions (EL20-P1, EL20-P2, EL20-P3, EL20-P4 and EL20-P5) that formed a soil-geochemical catena along the slope. Complex land cover found at the periphery. The explored soils were formed on silty

The soil-geomorphic evolution of a hillslope in hummocky moraine terrain in one of the most arid parts of the Palliser Triangle is reconstructed from ca. 12 600 BP to the present. A transect from a moraine plateau into an internally drained basin provided evidence for seven postglacial landscape cycles. Each cycle includes a phase of land-surface instability, marked by erosional and depositional imprints, and a phase of stability, marked by pedologic imprints. Five cycles of slope-wash-dominated erosion left behind four superposed downslope-thickening and downslope-fining sediment mantles and

AbstractA number of Byzantine tetraevangelia dating from between the tenth and twelfth centuries contain sequences of accompanying texts (among which patristic excerpts) that are very similar to those found in manuscripts with catena commentaries. This similarity raises the question of how the paths of such accompanying texts were formed during their transmission. Is it possible to define intermediate sources or relationships between manuscripts despite the complex traditions of such elements? This article first considers some methodological questions and then takes as a case study a tetraevan

Reactions of 1,10-phenanthroline (phen) and 2-(3,4-dichlorophenyl)acetic acid (dcaH) with Mn (CO3) (M = LiI, NaI and MgII; n = 1 and 2) in MeOH yield the mononuclear lithium complex aqua[2-(3,4-dichlorophenyl)acetato-κO](1,10-phenanthroline-κ2 N,N′)lithium(I), [Li(C8H5Cl2O2)(C12H8N2)(H2O)] or [Li(dca)(phen)(H2O)] (1), the dinuclear sodium complex di-μ-aqua-bis{[2-(3,4-dichlorophenyl)acetato-κO](1,10-phenanthroline-κ2 N,N′)sodium(I)}, [Na2(C8H5Cl2O2)2(C12H8N2)2(H2O)2] or [Na2(dca)2(phen)2(H2O)2] (2), and the one-dimensional chain magnesium complex catena-poly[[[diaqua(1,10-phenanthroline-κ2 N,N
