abstract. topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. graph theory is a delightful playground for the exploration of proof techniques in discrete mathematics and its results have applications in many areas of sciences. one of the us...

Various definitions for the QCD Debye mass and its evaluation are reviewed in a non-perturabtive framework for the study of screening of general static sources. While it is possible to perturbatively integrate over scales ∼ T and thus construct a 3d effective theory, the softer scales ∼ gT and ∼ gT are strongly coupled for temperatures < ∼ 10 GeV and require lattice simulations. Within the effe...

The present article aimed to describe the foundations and adequacy of the Grounded Theory (GT) to the construction of the substantive theory on the phenomenon of oral health care of institutionalized elderly people. GT is a methodology that allows formulating orderly abstractions from the real life data. Through this referential is possible to elaborate a relevant and functional theory in order...

We present a non-perturbative solution of large N matrix models modified by terms of the form g(TrΦ4)2, which add microscopic wormholes to the random surface geometry. For g < gt the sum over surfaces is in the same universality class as the g = 0 theory, and the string susceptibility exponent is reproduced by the conventional Liouville interaction ∼ eα+φ. For g = gt we find a different univers...

Contemporary middleware platforms provide a high degree of flexibility and configurability to support a large class of distributed systems found in a variety of domains, such as avionics, automotive, financials, healthcare and defense. Realizing the quality of service (QoS) properties of these systems requires mapping the domain-specific QoS requirements of these systems to the right set of con...

With the rapid increase in electronic and mobile commerce over the last few years, the academic literature on online and mobile customer behaviour has been fairly plentiful with a great deal of quantitative studies testing variations of existing customer behaviour theories. However, little attention has been given to qualitative studies in the field, which seek to explore new aspects of online ...

In this paper we describe an experiment in which we cast Generic Tasks into the mold provided by KEW. The result was advantageous for both GT theory and KEW GT bene tted by being formalized, and by gaining a computer implementation. KEW bene tted by having its strategy vindicated on a new target theory, and having its software more thoroughly tested. The experiment also exposed a weakness in th...

There are many challenges and criticisms attached to the conduct of research, none the least of which is a notion that much of the research undertaken in professional disciplines such as nursing may not have clinical and/or practical relevance. While there are a plethora of qualitative research methods that individuals must consider when designing research studies, one method stands out Grounde...

A Cognitive radio ad hoc network (CRAHN) is an ad hoc network of primary user (PU) nodes and secondary user (SU) nodes, wherein the SU nodes use the licensed channels of the PU nodes when not in use. As the availability of the PU channels fluctuates with time, communication topologies spanning the SU nodes have to be dynamically and frequently reconfigured. Given the complete knowledge of the a...
