Genesis of dewatering structures and its implications for melt-out till identification

Dewatering structures are a common feature used to identify melt-out till, and the lack of such structures in till could preclude deposition by melt-out.To assess the conditions under which melt-out till can be deposited without forming dewatering structures, I use geotechnical data and a quasi-two-dimensional model of geothermal melt-out. Critical discharge determined from geotechnical data su...

Stephen J. Hegner, 490317-0498, Bilaga till Ansökan Om Fft, Sida 1 Update Support in Component-based Database Systems

Modern database schemata are often large and complex, and a single user typically is afforded only limited access through a window, known as a view. The problem of supporting updates systematically through such views has long been known to be a difficult problem. Traditionally, the approach has been to limit the allowed updates to those which avoid or substantially limit so-called update anomal...

Metal complex of pioglitazone hydrochloride (PLZ) drug with Ni(II) ion is synthesized and characterized using analytical data, molar conductance, IR, UV-Vis, magnetic, mass spectral and XRD studies. From the analytical data, the complex is proposed to have general formula [(C 19 H 19 N 2 O 3 S)+ 2 Ni]2Cl-. The conductometric titration using monovariation method reveals that complex is L 2 M typ...

Optimizing Strip-Till and No-Till Systems for Corn

Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...
