The ruff of equatorial emission around the SS433 jets: its spectral index and origin

We present unique radio observations of SS433, using MERLIN, the VLBA, and the VLA, which allow us to, for the first time, properly image and derive a meaningful spectral index for the `ruff' of equatorial emission which surrounds SS433's jet. We interpret this smooth ruff as a wind-like outflow from the binary.Comment: 4 pages, 4 figures, to appear in Proceedings of the 4th Microquasar Workshop, eds. Ph Durouchoux, Y. Fuchs and J.

The Perspectives of Port Integration into the Global Supply Chains – The Case of North Adriatic Ports

Globalization, offshoring and the notable growth of containerization have changed the maritime transport and logistics chains. Ports became integral part of complex supply chains and serve as a logistics centres, add value, link flows and influence the supply chain patterns and processes. The port competitiveness is determined by its in-house strengths such as efficient freight handling and hinterland connections and by its position and links in the global supply chains. The aim of this paper is to investigate the importance of port integration in the supply chains overall and to analyse how North Adriatic Ports are integrated into the supply chains. The analysis is based on the sample of 939 firms aggregated by ports regions and classes level within Section H (Nace Rev.2). The assumption is that if the business cycle of all firms (classes) included in the port supply chain is correlated, it can indicate that the port is integrated in the supply chain. The results of our analysis are ambiguous, where the correlation is rather negative than positive. This paper provides the conceptual framework and outline the significance of this investigation for port operators, shipping lines, forwarders and other stakeholders

From Big Bang to Galactic Civilizations

Each scientific study emerges in its own particular time and marks a new step in the development of human thought.1 Big History materialized to satisfy the human need for a unified vision of our existence. It came together in the waning decades of the twentieth century, in part, as a reaction to the specialization of scholarship and education that had taken hold around the world. While this specialization had great results, it created barriers that stood in contrast to a growing unity among our global communities. These barriers were increasingly awkward to bridge, and, thus, Big History emerged as a successful new framework
