he North Taymyr ice-marginal zone (NTZ) is a complex of glacial, glaciofluvial and glaciolacustrine deposits, laid down on the northwestern Taymyr Peninsula in northernmost Siberia, along the front of ice sheets primarily originating on the Kara Sea shelf. It was originally recognised from satellite radar images by Russian scientists; however, before the present study, it had not been investigated

Cutting tool spontaneous failure such as, edge fracture and chipping are common phenomena in the metal cutting process, especially when difficult workpiece materials which have poor cutibility are met in the machining process. The tool failures are often caused by high mechanical and thermal stresses acting in it. Monitoring stresses acting in a cutting edge during machining process can provide mo

A method for studying PCB desorption behaviour from sediments using supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) is presented. Four sediments were investigated and extracted with supercritical carbon dioxide employing increasingly harsher extraction conditions ranging from 40 degrees C and 12MPa to 100 degrees C and 36.5 MPa. To ensure quantitative extractions, the

At moderate Reynolds numbers (10(4) a parts per thousand currency sign Re a parts per thousand currency sign 10(5)), the performance of lifting surfaces is strongly affected by the potential for laminar boundary layer separation and subsequent reattachment and the use of high-quality, low-turbulence wind tunnels is essential in characterising flight at comparatively small scales (where the wing ch

The aim of this study was to examine biochemical changes in cell wall carbohydrates and extensin proteins during long-term storage of carrots (Daucus carota L. cv. Nerac). During the storage period of 6 months, cell wall fractions were isolated from the carrot at various times for carbohydrate and protein analysis. Signs of extensin cross-linking and its concomitant insolubilisation in the cell wa

This article presents data from an on-going project comparing L1 and L2 acquisition of Swedish syntax. Within the L1 group, normal as well as specifically language impaired (SLI) children are included; the L2 group consists of pre-school immigrant children. The analyses of the data are made within a second language acquisition perspective with a focus on word order. One basic issue within second l

With the aim to improve our understanding of the structural basis for protein self-association and aggregation, in particular in relationship to protein refolding and amyloid formation, folding-related processes for human cystatin C have been studied. Using NMR spectroscopy together with chromatographic and electrophoretic methods, a self-association process resulting in dimer formation for protei
