In this study, the effects of blast furnace slag (BFS) and calcite on rheological properties self-compacting concrete (SSC) in meso macro scales were investigated. During preparation replicate samples, while BFS was replaced with cement at rate 10%, 20%, 30%, 40% by weight, added to 15%, 25% weight. The (plastic viscosity yield point) mini-slump flow values paste prepared determined. fresh cons...

Der Beitrag stellt auf Basis einer ersten empirischen Untersuchung den Status Quo des Geschäftsprozessmanagements (GPM) in der kommunalen Wirtschaftsförderung dar. Obwohl GPM in der öffentlichen Verwaltung ein Instrument von wachsender Bedeutung darstellt, wurde der Bereich kommunaler Selbstverwaltung hierzu bislang wissenschaftlich nicht evaluiert. Die vorliegende qualitative Voruntersuchung b...

In this paper we show how the abstract behaviours of higherorder systems can be modelled as final coalgebras of suitable behavioural functors. These functors have the challenging peculiarity to be circularly defined with their own final coalgebra. Our main contribution is a general construction for defining these functors, solving this circularity which is the essence of higher-order behaviours...

SUMMARY We present a new solution to the tree drawing problem that integrates an excellent tree drawing algorithm into one of the best text processing systems available. More precisely, we present a T E X macro package called TreeT E X that produces drawings of trees from a purely logical description. Our approach has three advantages: labels for nodes can be handled in a reasonable way; portin...

This paper discusses the " tricks of the trade " that legislatures in formerly de jure segregated states might use to maintain racial funding disparities in existence before Brown and whether such ploys might be vulnerable to legal challenges. The first section provides an overview of modern school finance formulas and explains how legislatures in de jure segregated states might use state aid p...

Abstract Some have argued it is possible to infer different groups’ contributions ethnic residential segregation from their individual neighborhood preferences. From this perspective, natives tend be more segregation-promoting than non-natives, since they prefer neighborhoods where are the majority. It remains unclear, however, whether holds when one evaluates within a dynamic perspective. Usin...
