The lower reaches of the River Ure, on flanks Pennine Hills in northern England, contain sedimentary and erosional landforms that are a record fluvial activity during deglaciation valley-glacier retreat at end last (Devensian) glacial period, subsequent post-glacial Holocene. Terraces channels, most which now relict features well above altitude present river, attest to impacts massive meltwater...

We use graceful labellings of paths to give a new way of constructing terraces for cyclic groups. These terraces are then used to find cyclic solutions to the three table Oberwolfach problem, OP(r, r, s), where two of the tables have equal size. In particular we show that, for every odd r ≥ 3 and even r with 4 ≤ r ≤ 16, there is a number Nr such that there is a cyclic solution to OP(r, r, s) wh...

Terracing is one of the oldest means of saving soil and water. The objective of this paper is to provide information on the different types of terraces and their functioning, and to describe advantages and disadvantages of terraces regarding their efficacy to stop or reduce soil erosion. Existing literature and information shows that terraces can considerably reduce soil loss due to water erosi...

The formation of epitaxial graphene on SiC(0001) surfaces is studied using atomic force microscopy, Auger electron spectroscopy, electron diffraction, Raman spectroscopy, and electrical measurements. Starting from hydrogen-annealed surfaces, graphene formation by vacuum annealing is observed to begin at about 1150°C, with the overall step-terrace arrangement of the surface being preserved but w...

The Miño River is one of the main Atlantic basins Iberia and preserves extensive Pleistocene deposits. However, there presently limited information concerning first human occupation history this region. Existing research undertaken across region has identified a significant number Large Flake Acheulean (LFA) sites with African affinities. These are associated former fluvial environments now pre...
