In this paper we study the L(2, 1)-labeling problem on oriented planar graphs with particular attention on the subclasses of oriented prisms, Halin and cactus graphs. For these subclasses more accurate results are presented. keywords: L(2, 1)-labeling, oriented graph coloring, digraphs, prisms, Halin graphs, cacti.

il-22 is a member of il-10 cytokine family which is believed to play an important role in inflammatory responses. il-22 has similarities with il-10 including conserved sequences with il-10. il-22 receptor is also comprised of two chains known as l-22r1 and l-10r2; supporting the speculation that the two cytokines may have similar effects. the aim of this study was to shed some light on the biol...

We reexamine radiative corrections to πl2 and Kl2 decays. We perform a matching calculation, including vector and axial vector resonances as explicit degrees of freedom in the long distance part. By considering the dependence on the matching scale and on the hadronic parameters, and by comparing with model independent estimates, we scrutinize the model dependence of the results. For the pseudos...

Intellectual control over software development projects requires the existence of an integrated set of explicit models of the products to be developed, the processes used to develop them, the resources needed, and the productivity and quality aspects involved. In recent years the development of languages, methods and tools for modeling software processes, analyzing and enacting them has become ...
