Spreading informationthrough a network of devices is core activity for most distributed systems. Self-stabilizing algorithms information spreading are one the key building blocks enabling aggregate computing to provide resilient coordination in open complex This article improves general block literature by making it perturbations, establishes its global uniform asymptotic stability, and proves ...

In general, acid aggregates are not used in combination with asphalt concrete because of their poor compatibility the binder, which typically results a scarce water stability concrete. present study, feasibility new approach based on granite fine aggregate alkaline limestone coarse and Portland cement filler has been assessed. The mineral chemical compositions these three materials have first a...

Land management affects soil structure and many other properties processes. Our objectives were to evaluate organic C (SOC), aggregate size distribution, aggregate-associated C, as affected by long-term land slope. A chronosequence of 38 on-farm sites with low high (5–18%) slopes was selected 5–40 yr management. The classified business usual (BAU) cropland (BAU-Crop), BAU pasture (BAU-Past), ne...

Article history: Received 16 September 2012 Received in revised form 4 September 2013 Accepted 17 October 2013 Available online 23 October 2013 In this paper we revisit the evidence recently provided by Philippon (2009) about the relationship among bond market's Q, stock market's Q and aggregate investments for the US. Specifically, we analyze the stability of the relationship between aggregate...

INTRODUCTION: The percentage of water stable aggregates (WSA) is a measure of resistance to breakdown by water and mechanical activities. Water stable aggregates improve soil water and air movement. Macro-aggregates (diam. > 250 m) are considered as a secondary soil structure associated with pores, microbial habitat, and physical protection of organic matter (Christensen, 2001; Carter, 2004). A...
