Landscape evolution theory suggests that climate sets the scale of landscape dissection by modulating the competition between diffusive processes that sculpt convex hillslopes and advective processes that carve concave valleys. However, the link between the relative dominance of hillslope and valley transport processes and landscape scale is difficult to(More)
This paper illustrates how archaeomagnetic dating can be used for palaeochannel fills within floodplain sequences. The sites investigated are palaeochannels associated with the mediaeval braided/anastomosing channels of an unstable reach of the River Trent at Hemington, north-west Leicestershire. This reach has revealed abundant archaeological remains(More)
Recently Kerr and Pan have proposed development of integrated image separating mixer circuits. To realize the 50 and 100 ohm terminations required by these circuits, a 4.2 K thin film resistor technology is required. It is also desirable to implement each resistor with one or two "squares" of material so that they are electrically short. Existing commonly(More)
CdTe nanocrystals were synthesized in aqueous solution using 1-thioglycerol and 2-mercaptoethanol as surface stabilizers. The nanocrystals were characterized by means of X-ray powder diffraction and UV-vis absorption measurements. The UV-vis absorption spectra exhibit two distinct transition lines. Comparison of the experimental measurements with the(More)
