Setting and nanostructure of slag-fly ash binders
Slag fly ash binders (SFB) are room temperature hardening binders that have high strength, reasonable setting time, and lower carbon footprint when compared to ordinary Portland cement (OPC). The precursors for SFB are industrial byproducts, namely slag and fly ash. The inexpensive nature of the …

Predicted and observed free-air gravity anomalies for delamination models of the formation of the Siberian Flood Basalts
… for the formation of the Siberian Flood Basalts (SFB) has yet to be discovered and adequately quantified. One theory proposes that thinning of the lithosphere due to delamination triggered the eruption. This model is characterized by a drip of denser material within the mantle, and because it …

Genetic analysis of reproductive and nut traits in almond [Prunus dulcis (Mill.) D.A. Webb]
… polymorphism in the region where the S-RNase and SFB genes are located and considerable differences in the number and locations of long terminal repeat retrotransposons. There are about 50 known S alleles, of which one confers self-fertility. For some of these, complete or partial S-RNase and SFB …

A structural framework for assembly modeling and recognition
… a suitable setting to test their algorithms. The SFB 360 at Bielefeld University is among those projects that pioneered this idea. It aims to develop a robot that - instructed by spontaneous speech and gesture - assembles wooden toy objects. As these parts can be arbitrarily arranged in the …

The Neoproterozoic São Francisco Basin, central Brazil: tectonic evolution, paleoclimate, and mineral systems
The São Francisco Basin (SFB; ca. 950-550 Ma), central Brazil, hosts sediments deposited during most of the Neoproterozoic Era and so is a critical repository of information concerning the evolution of the late pre-Cambrian world. Detailed study and revision of existing stratigraphy reveals that …
