The vortex dominated flows in the near field of jets from notched circular nozzles are investigated using direct numerical simulation. The nozzles studied include a normal circular nozzle, a V-shaped notched nozzle, and a...

Child sex tourism is an obscure industry where the tourist‟s primary purpose is to engage in a sexual experience with a child. Under international legislation, tourism with the intent of having sexual relations with a minor is in violation of the UN Convention of the Rights of a Child. The intent and act is a crime and in violation of human rights. This paper examines child sex tourism in the P...

A5 an increasing number of organizations reach across national boundaries, organizational research increasingly addresses the question ofhow national culture influences individual behavior (Erez & Earley, 1993; Hofstede, 1991). Researchers face a choice among numerous definitions of culture and methods for studying it that have been developed in different academic disciplines (Keesing, 1974). A...

In this paper we address the problem of defining social roles in MAS. Social roles provide the basic structure of social institutions and organizations. We start from the properties attributed to roles both in the MAS and the Object Oriented community, and we use them in an ontological analysis of the notion of social role. We thus identify as the main properties of social roles being definitio...

Triple-stranded DNA structures can be formed in living cells, either by native DNA sequences or following the application of antigene strategies, in which triplex-forming oligonucleotides are targeted to the nucleus. Recent studies imply that triplex motifs may play a role in DNA transcription, recombination and condensation processes in vivo. Here we show that very short triple-stranded DNA mo...

As investments in Knowledge Management (KM) initiatives grow, there is an increasing need for coherent and comprehensible principles and practices to guide KM implementation efforts. Academics and practitioners have proposed various KM Maturity Models (KMMM) to formally capture the KM development process by assessing the extent to which KM is explicitly defined, managed, controlled, and effecti...

The dynamic transfer of a conjugated polymer's organization-dependent properties from the solution state to the solid film state was probed by circularly polarized luminescence (CPL) and circular dichroism (CD) spectroscopy. Different supramolecular organizations within films and aggregate solutions of a chiral poly(p-phenylenevinylene) derivative led to opposite CPL and CD spectra. These drama...

Relaxed circular, covalently closed simian virus 40 DNA molecules were associated with the four histones that are present in virions. In electron micrographs the resulting complexes appear twisted, with globular structures (nucleosomes) along the DNA. Incubation with an untwisting extract converts the twisted complexes to relaxed structures. Extraction of the DNA from the relaxed complexes yiel...

We report on the use of the generic programming paradigm in the computational geometry algorithms library cgal. The parameterization of the geometric algorithms in cgal enhances exibility and adaptability and opens an easy way for abolishing precision and robustness problems by exact but nevertheless eÆcient computation. Furthermore we discuss circulators, which are an extension of the iterator...

We examined the structural and functional basis for pacemaking by interstitial cells of Cajal (ICC) in circular smooth muscle of the canine ileum. Gap junctions were found between ICC of myenteric plexus (MyP), occasionally between MyP ICC and outer circular smooth muscle cells, between individual outer circular smooth muscle cells, between them and ICC of the deep muscular plexus (DMP), and be...
