Atom-probe tomography, transmission electron-microscopy, x-ray diffraction, and firstprinciples calculations were employed to study the (i) compositional evolution of GPII-zones and "!-precipitates, and (ii) solute segregation at !-Al/"!-interfaces in Al-4 wt. % Cu alloys. GPII zones are observed for aging at 438 K for 8 h, whereas higher aging temperatures, 463 K for 8 h and 533 K for 4 h, rev...

Th e aim of the research was the comparison of economic feasibility of most common conventional and organic farm production in Slovenia. Th e methodology of an integrated deterministic technologic-economic simulation system KARSIM 1.0 (DSM) application for cost analysis and decision-making support on farms is described in this article. Th e direct simulation model result is an individual conven...

We measured the effects of a diet in which D-β-hydroxybutyrate-(R)-1,3 butanediol monoester [ketone ester (KE)] replaced equicaloric amounts of carbohydrate on 8-wk-old male C57BL/6J mice. Diets contained equal amounts of fat, protein, and micronutrients. The KE group was fed ad libitum, whereas the control (Ctrl) mice were pair-fed to the KE group. Blood d-β-hydroxybutyrate levels in the KE gr...

Partially deuterated Ca3Al2(SiO4)3 x(OH)4x hydrates prepared by a reaction in the presence of D2O of synthetic tricalcium aluminate with different amounts of amorphous silica were characterized by Si and Al magic-angle spinning nuclear magnetic resonance (NMR) spectroscopy. The Si NMR spectroscopy was used for quantifying the non-reacted silica and the resulting hydrated products. The incorpora...

It is of great importance to clarify the atomic structure and strength of interfaces between metal and Si substrate in an electronic device. While interaction between atoms near the interface is complicated, ab initio molecular dynamics makes it possible to analyze such properties of interface. In this study, in order to evaluate structure and strength of Si/Al interface, evaporation process of...
