In this paper we briefly present our views on composability of models and interoperation of simulations; we introduce our simulation software framework, namely Simulation Modelling Architecture (SiMA), and we present our contributions to the underlying formal model (i.e. discrete event system specification). We also present our simulation construction environment, which supports composability o...

Inspection of the genome sequence of Lactobacillus casei ATCC 334 revealed two operons that might dissimilate the five isomers of sucrose. To test this hypothesis, cells of L. casei ATCC 334 were grown in a defined medium supplemented with various sugars, including each of the five isomeric disaccharides. Extracts prepared from cells grown on the sucrose isomers contained high levels of two pol...

A modified strain-induced melt activation (SIMA) process was applied and its effect on the structural characteristics and hardness of the aluminum alloy Al–12Zn–3Mg–2.5Cu was investigated. Specimens subjected to a deformation of 40% at 300 °C were heat treated at various times (10-40 min) and temperatures (550-600 °C). Microstructural studies were carried out using opt...

The aim of this study is to describe the morphology of the roots and root canals of permanent lower second premolars (LP4s) with fully developed roots of five hominin groups: Homo sp. (ATE9-1 specimen) from Atapuerca-Sima del Elefante locality, H. antecessor (ATD6-4 and ATD6-125) from Atapuerca-Gran Dolina TD6 locality, H. heidelbergensis from Atapuerca-Sima de los Huesos locality, H. neanderth...
