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 …

Modulation of Obesity and its Sequelae by Microbiome/Immune System Interactions
… the role of Segmented Filamentous Bacteria (SFB), a specific constituent of the intestinal microbiota with defined immunostimulatory properties, in the development and maintenance of obesity and in the progression of a particular sequelum of obesity, non-alcoholic steatohepatitis. Our data …

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 …

Classification of building design information
… building elements and components, such as CI /SfB and UDC, were developed to classify documents. A classification/coding system for use with computer aided design has to be able to convey detailed information about the features and properties of components. Previous studies of the use of …

From Flare to Repair: Commensal Bacteria's Influence on Inflammation and Wound Healing
… microbe, segmented filamentous bacteria (SFB), drive neuroinflammation in the absence of regulatory T cell control. These T cells become dysregulated in the gut, gain a license to cross the blood brain barrier, and are re-stimulated by host proteins in the CNS to cause neuroinflammation. …

Understanding ERP adoption and family involvement in UK’s retail small family businesses
… within UK’s retail Small Family Businesses (SFBs). The study is important because some studies posit that family involvement in business could be leveraged for a successful adoption of technology, but others suggest that family involvement could as well be a hindrance to adopting an ERP …

Untersuchungen zur Signaltransduktion Ajoen-induzierter Apoptose in Leukämiezellen
Die vorliegende Arbeit wurde durch den SFB 369 (Teilprojekt B7) unterstützt. Sie sollte auf Basis der bereits vorliegenden Erkenntnisse klären, welcher Mechanismus der Apoptoseinduktion durch Ajoen in HL-60 Zellen zu Grunde liegt. Dirsch et al. 5 zeigten bereits 1998, dass Ajoen Apoptose in humanen …

Studio molecolare dei meccanismi dell'autoincompatibilità gametofitica in pero europeo (Pyrus communis)
… motif, called S-Locus F-box (abbreviated SLF or SFB). Since F-box proteins are best known for their participation to the SCF (Skp1 - Cullin - F-box) E3 ubiquitine ligase enzymatic complex, that is involved in protein degradation through the 26S proteasome pathway, the male determinant is supposed …

Using prophylactics to improve resistance against Enterobacteriaceae in chickens
… treatment hastened the rate and consistency of SFB attachment in the ileum, with birds as young as 4 days old exhibiting SFB colonization. Using FITC-dextran to measure gut permeability, SPORE birds exhibited reduced gut leakiness versus CON. To determine immunometabolic shifts in the ileum, the …
