The preparation method of a polymer composite and the filler loading are amongst the factors that influence the properties of the final composites. This article studies the effect of these factors on the thermal stability and thermal degradation kinetics of poly(methyl methacrylate) (PMMA)/mesoporous silica (MCM-41) composites filled with small amounts of MCM-41. The PMMA/MCM-41 composites were prepared...
This paper presents a study on how to improve a distributed information collecting system in which information is collected by a multi-agent system constituted by communicating agents, assuming the hypothesis that some agents of this system can deliberately (liar agents) or in good faith (defective agents) produce or communicate incorrect information. To ensure the coherence of the information system...
In this paper, Reactive Multi-Agent Systems handle complex assignment problems as decentralized negotiating problems. Each agent locally acts in order to make the system reach a satisfying configuration. We address here, the designing problem: how to accurately communicate the problem to agents, and increase their ability to coordinate? We identify two main aspects to consider: (1) how to express...
In the present paper the chromosome complement (n = 13; 2n = 26) of the common leech Haemopis sanguisuga (L.) (Annelida: Hirudinea: Hirudinidae) was analyzed using banding techniques and fluorescent in situ hybridization (FISH) with three repetitive DNA probes [ribosomal DNA (rDNA), (TTAGGG)n and (GATA)n]. FISH with the rDNA probe consistently mapped major ribosomal clusters (18S–28S rDNA) in...
