This paper presents an ontological analysis of the EPC (Event-driven Process Chain) business process modeling notation supported in the ARIS Toolset. This ontological analysis provides an interpretation of the modeling elements in EPC diagrams in terms of the UFO foundational ontology. This enables us to define the precise real-world semantics for business(More)
This paper focuses on the issue of ontological interpretation for the ARIS organization modeling language with the following contributions: (i) providing real-world semantics to the primitives of the language by using the UFO foundational ontology as a semantic domain, (ii) the identification of inappropriate elements of the language, using a systematic(More)
In this paper, we provide a semantic foundation for role-related concepts in Enterprise Modelling. We use a conceptual modelling framework to provide a well-founded underpinning for these concepts. We review a number of Enterprise Modelling approaches in light of the concepts described (namely, ARIS, Archimate, DoDAF, RM-ODP and BPMN). This allows us to(More)
Biofilms are highly structured microbial communities that are enmeshed in a self-produced extracellular matrix. Within the complex oral microbiome, Streptococcus mutans is a major producer of extracellular polymeric substances including exopolysaccharides (EPS), eDNA, and lipoteichoic acid (LTA). EPS produced by S. mutans-derived exoenzymes promote local(More)
This paper focuses on the issue of ontological analysis for organizational structure modeling in the ARIS method with the following contributions: (i) an interpretation of the language in terms of real-world entities in the UFO foundational ontology; (ii) the identification of inappropriate elements of the language, using a systematic ontology-based(More)
The effect of adding SO2 on the structure and dynamics of 1-butyl-3-methylimidazolium bromide (BMIBr) was investigated by low-frequency Raman spectroscopy and molecular dynamics (MD) simulations. The MD simulations indicate that the long-range structure of neat BMIBr is disrupted resulting in a liquid with relatively low viscosity and high conductivity, but(More)
The alternative low-spin states of Fe(3+) and Fe(2+) cytochrome c induced by SDS or AOT/hexane reverse micelles exhibited the heme group in a less rhombic symmetry and were characterized by electron paramagnetic resonance, UV-visible, CD, magnetic CD, fluorescence, and Raman resonance. Consistent with the replacement of Met(80) by another strong field(More)
PURPOSE To compare fluid replacement therapy with Hydroxyethyl starch 6% (HES) versus Ringer's lactate (RL) in a rodent model of non-septic renal ischemia. METHODS Forty male Wistar rats were randomized to receive HES 2 ml.kg(-1).hr(-1) or RL 5 ml.kg(-1).hr(-1) that underwent 30 minutes of renal ischemia followed by reperfusion. Twelve hours after kidney(More)
The deprotonation of the push-pull molecule 4-hydroxy-4'-nitroazobenzene leads to a substantial variation in the charge distribution over the donor and acceptor moieties in the D-pi-azo-pi-A system. The extra charge stabilizes the excited state, leading to a drastic red shift of ca. 100 nm in the lambda max of the electronic transition and consequently(More)
