This paper describes the optimization of existing technology for fabrication superconducting films and high-quality tunnel junctions on a magnetron sputtering facility. To expand frequency range to 1.1 THz obtain limiting parameters elements, regimes production Nb, NbN, NbTiN were optimized. These are used fabricate superconductor-insulator-superconductor Nb/Al--AlN/NbN junctions. Al required c...

Cooperative business processes supporting the collaboration of companies and organizations are of increasing importance as they help to reduce the complexity of cooperation scenarios and optimize time and costs. More and more organizations use Internet technology such as Web services to support their cooperative business processes. Web services are an emerging technology to encapsulate services...

daniels, porteny and urrutia et al make a good case for the idea that that public decisions ought to be made not only “in the light of” evidence but also “on the basis of” budget impact, financial protection and equity. health technology assessment (hta) should, they say, be accordingly expanded to consider matters additional to safety and cost-effectiveness. they also complain that most hta re...

Microquasars are X-ray binary stars with the capability to generate relativistic jets. It is expected that microquasars are γ-ray sources, because of the analogy with quasars and because the theoretical models predict emission at such energy range. In addition, from observational arguments, there are two microquasars that appear as the possible counterparts for two unidentified high-energy γ-ra...
