The title compound, C(26)H(22)N(4)O(2)·2CH(3)OH, was synthesized and characterized by (1)H NMR spectroscopy and X-ray structure analysis. There is one half-mol-ecule in the asymmetric unit with a centre of symmetry located at the centre of the benzene ring. The two bridged naphthyridine ring systems are in an anti-parallel orientation. In the crystal structure, O-H⋯N, C-H⋯O and C-H⋯N inter-acti...

Even though ICT convergence is a well-established and adopted concept, there is no consensus about the underlying software engineering approach to convergent ICT systems. Telecom engineers and software engineers traditionally use different approaches when developing services and applications. A main question is whether or not the differences are justified and should be maintained in the context...

Drawing from literacy studies and research in media education, this article contends that a series of conceptual gaps need to be bridged order have better understanding how these traditions can contribute redefining the field digital social work. The work should move towards more critical-oriented dimension so internet not simply considered (as it is often case), as mere tools improve professio...

The sliding tubule model of ciliary motion requires that active sliding of microtubules occur by cyclic cross-bridging of the dynein arms. When isolated, demembranated Tetrahymena cilia are allowed to spontaneously disintegrate in the presence of ATP, the structural conformation of the dynein arms can be clearly resolved by negative contrast electron microscopy. The arms consist of three struct...
